Problems solved by technology

The structure of the door lock with the clutch on the front panel is simple, but the front panel is damaged, and it is easy to open the door lock when the front panel is removed; the lock body of the door lock with the clutch inside the lock body is an electric lock body, and there is a signal on the lock body Cables, power supply lines, the installation of the lock body is more troublesome, and due to the addition of electrical components, the reliability of the lock body is reduced

In the prior art, the inner part of the lock is a force-bearing part that receives the action of opening and closing the door. It is provided with a square force-bearing hole that is completely matched with the square steel. When the front panel is destroyed, the lock body is exposed, and the lock can be driven by turning the square steel. The parts in the body rotate to realize unlocking, so the lock body can be opened easily, and the security of the door lock is not high
