In recent years, the number of cases of technical burglary burglary has been on the rise. It is estimated that tens of thousands of cases of burglary have been smashed every year in the country. For example, in the residential area of ​​a residential area in Dalian, two households were stolen in the morning. After analyzing the theft elements, they used technology to unlock the burglary, and the value of theft property was more than 100,000 yuan. Another example is that in Nanjing, within one day, eight cases of technical burglary and burglary occurred, and six more occurred the next day. After the police platform and the case, it was found that more than 80 cases of similar cases occurred.
The theft of theft by theft elements is not particularly high. However, there are many loopholes in the design of locks and door structures on the security door, which provides convenience for the theft.
The door is the barrier to the home, and the lock is the heart of the door. The lock is used to ensure that the door is not opened effectively; the lock itself has a problem, and then want to seek safety from such a lock, it is not the same as the fish. In an era when science and technology are very developed, why are locks that are related to the security of thousands of households so vulnerable? The author believes that there are mainly the following reasons:
First, the national lock standard is backward, and the existing standards have not adapted to the current social situation.
GAT73-1994 Mechanical anti-theft lock The public safety industry standard of the People's Republic of China 5.3 anti-destruction function: The opening time of the A-level anti-theft lock technology is not less than 1 minute, and the opening time of the B-level anti-theft lock technology is not less than 5 minutes. Can the lock that can be opened in more than a minute be able to talk about theft?
Technology opening refers to the ability of a professional who resists the use of special tools to open the lock using special tools. As everyone knows: the time required to open the same lock technically depends on the person. For the novice, the opening time is longer. For those with higher levels, the opening time must be shorter. What technical standards are used to measure the time when technology is turned on? When the relevant departments conduct product quality inspection, it is difficult for the quality inspection department personnel to have a technical unlocking master, and the operability of the inspection is lacking. In addition, with the development and progress of the unlocking industry (known as the "Locksmith" in the national standard), new quick-release tools have emerged, and locks that were previously considered to be difficult to open are now easy to open. Such a provision is neither scientific nor rigorous, so it is ineffective.
Clause 5.1.4 of the standard stipulates that: the mechanical anti-theft lock opened by the key, the lock cylinder should not be a single-row marble structure, and may be a multi-row marble structure, a magnetic marble structure, a blade structure, a lever structure or a single-row composite structure. The provisions of this paragraph show that the standard setters do not understand the principle of unlocking and the opening technology, which is misleading when the security door manufacturer chooses to install the lock. The mechanical lock of the magnetic bullet structure is the most unsafe lock. It can be easily opened with a simple tool. How can it be called a mechanical anti-theft lock? Take Hebei Province as an example: In 2004, thefts targeted 13 mechanical locks on the structure of magnetic marbles in just a few days.
Theft of a large number of residents’ property has made the residents who install such locks and security doors fearful every day. After the police solved the case, the Evening News published a message entitled "Deciphering the Keys to Make the Magnetic Locks the Same Form", and immediately set off an uproar in the society. The thief can easily enter the house with the "master key"! What is even more shocking is that there are also expensive domestic brands in the security door where such magnetic locks are installed. At the same time, several security door manufacturers and dealers have also discovered this problem, and immediately declare that they will no longer use such locks; and promise to the user: free replacement of the security door that has been sold to install such locks.
Second, driven by economic interests, lock manufacturers are shoddy to reduce costs.
Under the market economy conditions, lock manufacturers often put economic benefits first. In order to reduce production costs and use low-tech processing equipment, the precision of lock parts is poor, the degree of standardization is low, keys and lock cylinders, lock cylinders The gap with the lock cylinder hole is large, the error of the length of the marble is large, and the key tooth is arranged incorrectly. Some even knock off the part of the lock cylinder that opens the separation surface, so that the key can be opened smoothly. These reasons not only make the difficulty of unlocking the technology greatly reduced, but also greatly increase the mutual opening rate. The mutual opening rate of the lock is an important indicator for assessing the security performance of a lock. If the mutual opening rate is unqualified, it is possible to use the key of the house to open the lock of the other person's home, and even open the locks of several households or open each other. For example, in a college in Hefei Economic and Technological Development Zone, a student opened the door of 20 dormitory rooms with his own bedroom key and started crazy theft. Another example was the residents of Kunyu South Street in Jiangjiatun Community, Yantai City. A key can open the security door of the entire building. Many security door manufacturers do not have their own lock factory. Their locks are all purchased by bidding. Whoever uses the cheapest? With such inferior locks, how can we ensure the security of the security door?
Third, the spread of unlocking technology and the proliferation of unlocking tools have greatly increased the hidden dangers of social security.
The unlocking technology was originally a special means of a certain department. After the 1990s, due to the lack of laws and regulations, the unlocking technology began to flood. Especially through the large platform of the network, it is easy to unlock the technology and unlock the tools. Just enter the "unlock tool, unlock technology" entry on your computer and you can search for hundreds of related information. In addition to providing unlocking tools on almost every website, locksmith training, sale of unlocking training materials or CD-ROMs, and commitment to non-professionals are also available.
In 2005, China’s tenth batch of national professional standards was officially released by the Ministry of Labor and Social Security. Locksmiths (defined as those engaged in the installation, repair and opening of locks) were formally incorporated into the National Occupational Classification. . From then on, the lock repairman (the “locksmith†in the society) entered the society as an industry recognized and allowed by the state. Among the many employees, the personal qualities are mixed, and some people are free to teach the unlocking technology to non-employees. It is inevitable that the minded person will master this technology. Although the Public Security Bureau of the Ministry of Public Security and the State Administration for Industry and Commerce jointly issued the "Notice on Regulating the Operation of Unlocking Business Units to Strengthen the Management of the Unlocking Industry", the implementation situation is different. The local public security departments are the departments in charge of special industries, but they are also limited to programmatic management. They are not deep and not detailed, and many measures cannot be implemented. Unlocking technology and unlocking tools are indispensable, which will inevitably lead to an increase in social security risks and criminal offences. For example, a criminal named Ling Weiquan in Guangzhou called himself "Guangzhou Lock King", which can open various types of locks in a very short time. Within one year, the criminal gang entered the house to steal more than 200 cases and stole more than 10 million yuan worth of property. Cases like this are not cases in certain areas, but occur frequently throughout the country.
Fourth, the design of the security door structure is unreasonable, leaving the opportunity for theft elements.
In order to attract more customers' favor and achieve unique goals, some security door manufacturers have installed self-collision locks or double-fast locks in recent years. The so-called self-collision lock is when the security door is closed, the three horizontal bolts on the lock body are ejected together with the anti-theft latch on the door to achieve the purpose of locking. The lock hole of this lock has a cylindrical shape and a cross shape. This kind of lock seems to be convenient for the user on the surface, and there are actually huge security risks. Because the lock does not need to open the lock cylinder, the linkage mechanism of the lock body can be directly opened to open the door. The quick-opening tool for this type of lock also came into being, and it took only 20 seconds to open the door; that is, using the key to unlock it did not help. The so-called double-fast lock has a fast locking function, and the handle can be lifted upward by 40 degrees in the outdoor, so that the main locking tongue can be quickly locked, and the trouble of using the key is eliminated. Although this kind of lock has the function of key unlocking, but because the seller does not publicize enough, the user does not know how to use it. This type of security door can be opened by a special tool using a door mirror (commonly known as a cat's eye).
In summary, several main reasons have caused the technology to unlock and steal theft, and the property of the people has been infringed by lawless elements. How to solve this national problem? The author believes that the following work should be done:
First, the relevant state departments will issue new standards for anti-theft locks and anti-theft doors as soon as possible to adapt them to the development of technology unlocking. The technical indicators of the C-class and D-class anti-theft locks are established, and it is mandatory to specify which level of locks are allowed to be installed on the security door. In the revision of the anti-vandal function clause, it is necessary to recruit experienced locksmiths to participate in or solicit their opinions, and fill in the gaps in the relevant departments that do not understand the unlocking technology or the ability to destroy.
Second, the anti-theft lock and security door for mandatory inspection and compulsory certification, the product must comply with national standards and technical regulations. Promote the quality management of products and protect consumer rights. The relevant departments should limit the locks that do not meet the standard and must not be installed and sold on the security door. For units that produce and sell products, they must be severely punished to achieve the effect of killing one hundred and one hundred. Through the corresponding industry associations, we will vigorously promote anti-theft locks with high anti-destructive capabilities and cannot be opened by technology, such as idle locks.
Third, establish an accountability system to achieve the unity of power and responsibility. The designated certification body, testing organization and inspection organization that undertake the certification task shall not be held responsible for the performance of the functional organization or bear the economic loss after the product certification, due to product quality or technical indicators; How much responsibility is to be undertaken. Put an end to the current situation of a lot of relevant management departments, there is no problem with a department.
4. The public security department shall strengthen legislation and severely crack down on units or individuals that illegally teach unlocking technology and illegally produce and sell unlocking tools. Block the sale of forced unlocking tools (also known as violent unlocking tools) website.
If the above work is done well, it will promote the development of China's lock industry and improve the quality of lock products; thus ensuring social stability and safeguarding the legitimate rights and interests of consumers.
