Some locks are "second" to see if your home is safe?

In order to thoroughly implement the deployment requirements of the Municipal Public Security Bureau on strengthening the construction of community public security prevention and control system, mobilize the masses to raise their awareness of security and actively participate in security activities. During the “11th” holiday period, the Basic Work Office of the Municipal Public Security Bureau will be associated with the Public Security Bureau of the High-tech Zone. In Nanhu Garden, the jurisdiction of the Huahua Road Police Station, a joint security campaign was held to build a security line and build a harmonious community – the police and the people to send technology to prevent the community.

It is reported that this kind of activity will be gradually pushed out in the whole city by the mode of piloting and post-exploration. By encouraging residents to choose economic and practical, preventive effects, good physical defense and technical defense products, the work of science and technology benefiting the people will be truly implemented. Effective.

At the event site, the staff from the Shandong Provincial Security Equipment Special Committee also conducted a technical unlocking demonstration on the spot to remind the residents to upgrade their own door locks in time. "The launch of this activity is an innovative measure to broaden the prevention of ideas, integrate social resources, and implement cross-border cooperation. It aims to explore a new way for the police and the people to work together to maintain social security." Municipal Public Security Bureau Basic Work Office Director Tian Jianke said.

Demonstration

●Demonstration locks

Cross wire locks, padlocks, exterior door locks and lock cylinders are all Class A lock cylinders.

● unlock time

The four lock sequences are open for 34.4 seconds.

The reporter noticed that some lock cylinders only need a tool like a universal key, inserted into the lock hole, and twisted a few times, it will be opened. Some lock cylinders can be opened by using a single hook and other tools to simulate the key unlocking principle. The most surprising thing is that the anti-theft door lock cores that many families use today can be opened with just a lock lock tool. I saw the expert insert the key into the lock cylinder, tapped the key with the wrench's head, and then twisted the key a few times, the lock cylinder was opened.

●Expert analysis

At present, the lock core level on the market is divided into three levels, from low to high, respectively, A, B, and C (super C). Among them, the cross lock and the one-word lock are all A-class lock cylinders, and the general technical unlock can be completed within one minute. Compared with the A-class lock cylinder, the biggest difference of the B-class lock cylinder is that there is one more row of marbles, but the structural principle of the B-class lock core is the same as that of the A-class lock cylinder, and it is easier to open. At present, it is relatively safe to use a double-row vane with a V-shaped side cylinder to lock the C-class lock cylinder, which is difficult to open by technical unlocking.

How to choose a lock with high anti-theft coefficient

● Look at the "teeth" of the key. The more teeth, the deeper the teeth, the more complicated the arrangement, and the better the anti-theft performance.

● Pick the lock on the scale of two, one to the weight, the second to see the lock core. The same material of the lock cylinder, the heavier the weight, the more beads in the lock core, the better the anti-theft function.

● Select the lock core to see the material color, than the color, look at the work. The good quality lock core has a smooth surface and bright color. Among them, the dark yellow color is the copper core, which is relatively strong and has good anti-theft performance. On the contrary, the color of the lock core is dim, and the color is gray and the bubbles are zinc alloy, and the anti-theft performance is general.

●Select the lock core produced by regular manufacturers, the quality is guaranteed.

● Select a lock cylinder with a high level of anti-theft.

Experts suggest that you should pay attention to maintaining the family lock. If you need to unlock or change the lock, you must find the formal unit in the public security organ's record, and check the qualifications of the unlocked personnel. Don't be tempted to believe the information on the small advertisements that are randomly posted at the door, so as to avoid installing unqualified locks or your own keys. It happened when someone was stolen.
