Problems solved by technology

This preload is either due to the deformation of the door panel, or due to the pressure difference between the inside and outside of the door panel, or because the door opener inadvertently pushes and pulls the door panel. The friction force between them is increased, so that the force generated by the electromagnet is not enough to overcome the friction force, resulting in the failure of electronically controlled unlocking

Embodiment Construction

[0024] Hereinafter, the present invention will be described in detail through exemplary embodiments. However, it should be understood that without further description, the elements, structures, and features in one embodiment can also be beneficially combined into other embodiments.

[0025] See figure 1 as well as Figure 4 ,Such as figure 1 with Figure 4 As shown, the locking device of the present invention includes a housing, and a power mechanism 1 and a lock 5 arranged inside the housing. The power output end of the power mechanism 1 is connected to one end of the connecting rod 3, and the other end of the connecting rod 3 is connected to the brake The unit and the brake unit can drive the lock buckle to rotate, and the position of the lock buckle changes, so that the lock tongue is fixed or loosened in the lock buckle to realize the locked or unlocked state. Wherein, the above-mentioned power mechanism 1 may be a motor, a spiral tube, etc., which is not limited here, as lon...

Abstract

The invention provides a buckle device which comprises a power mechanism, a connecting rod, a brake unit and a buckle. The power output end of the power mechanism is connected with one end of the connecting rod. The other end of the connecting rod is connected with the brake unit. The brake unit drives the buckle to rotate. The power mechanism is connected with the connecting rod through a gear to output and transfer power of the power mechanism to the connecting rod. The buckle device overcomes precompression through rigid meshing of the gear.

Description

Technical field [0001] The invention relates to a lock, in particular to a locking device. Background technique [0002] When the door is closed, the bolt of the door lock installed on the door panel enters the groove of the lock device. After the lock catches the bolt, the most common way in real life is to use a key to open, that is, use the key to make the bolt Shrink backwards. However, after the electric control lock device is installed, it can also be opened with electricity to release the lock of the lock device. Even if the lock tongue is not retracted backward, the door can be pushed open. [0003] However, the most frequently encountered and difficult to overcome situation of electronically controlled locks is that the state of the door exerts a pre-pressure on the lock. This pre-pressure is either due to the deformation of the door panel, or the pressure difference between the inside and outside of the door panel, or the door opener inadvertently pushing and pulling th...
