Should smart door locks be equipped with top and bottom hooks?

Should smart locks be equipped with top and bottom hooks? After all, some friends have become accustomed to the existence of top and bottom hooks, and psychologically believe that it is safer to install top and bottom hooks. What is the truth? Let's understand the disadvantages of installing top and bottom hooks on smart locks.

In the early days, the design of anti-theft doors was more focused on "anti-prying" design. In addition to the higher security of the key used to open the door, anti-theft doors will also be designed with multiple lock tongues to prevent someone from entering the room by prying the door. At this time, the top and bottom hooks came into being.

Because prying the door is a single-point operation, the anti-theft door manufacturer added two sets of lock tongues on the upper and lower edges of the door, which is the origin of the top and bottom hooks for the entrance door. Later, with the continuous development of the Internet, the threshold for people to obtain knowledge has become lower and lower. Some people began to share the method of unlocking from a technical point of view, but it was used by people with ulterior motives as their own technical method of unlocking. "Prying the door and pressing the lock" is no longer feasible. It has become "no technical content at all", and the sky hook is not so important in the face of technical unlocking, because as long as the lock core is opened, all the lock tongues will be retracted obediently, and the sky hook is no exception.

The development of high-rise buildings has also limited the necessity of sky hooks. As we all know, when a fire occurs in a high-rise building, the number of casualties is very high. When firefighters enter a high-rise building to check the situation, they will use demolition tools to directly demolish the door.

In front of professional demolition tools, anti-theft doors without sky hooks only need to break one lock point to open the door, but the sky hook will have two or more lock points, which will delay the rescue time at this time and lose the safety effect. Domestic fire doors also require that they are not allowed to be equipped with sky locks while being anti-pry.

Now, on smart locks, many lock bodies are driven by internal circuits, which means that electricity is used. The power supply on smart locks is usually battery-powered, which creates certain requirements for battery life. And the electric lock body drives the sky hook, which requires more power, which means it is more power-consuming.

In addition, the push-pull lock body does not support the sky hook in structure, while other lock bodies that support the sky hook will have two more "wings" than ordinary lock bodies, and will be separate models. Therefore, when purchasing the sky hook, you should ask the customer service whether the lock body supports the sky hook.

As for whether the sky hook is necessary, the editor believes that if you live in a high-rise or a community with relatively complete security, there is no need to install the sky hook. If it is not a high-rise residential building, and there is a large flow of people near your home, and the anti-theft door at home also has a sky hook, then try to buy a smart lock that supports the sky hook, without disassembling the sky hook.

People often have an inherent concept that the king lock body plus the sky hook will be safer. The safety here only refers to the safety of preventing violent door breaking, not the safety of preventing theft. The biggest role of the sky hook on the door is to prevent strong impact and strong door breaking, because it is a well-shaped structure with the door frame, which is stronger than the lock with only one side point. However, the sky hook is a special product of my country's national conditions. There is no sky hook product abroad. In the use of mechanical locks, installing a sky hook will indeed increase the degree of safety. However, in the installation of smart locks, the sky hook has become an outdated product.

The sky hook will greatly increase the failure rate of smart locks, shorten the service life of smart locks, and often play a counterproductive role in critical emergency situations. For example, when a fire occurs, the door body is deformed by high temperature evaporation. At this time, even the mechanical lock hole is twisted and cannot be opened. When the fire rescue personnel are ready to force the door in, they are often stuck by the sky hook, resulting in a delay in the opportunity to rescue people.

This is not an isolated case. In so many accidents across the country that require breaking the door for rescue, many people have lost their lives because of a small sky hook. In addition, some foreign imported brands are basically small lock bodies that cannot carry sky hooks.

Therefore, although the sky hook can play a role in ensuring residential safety, considering comprehensively, if a fingerprint lock product with higher security is installed, then the sky hook is not needed.
