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] In the following, the present invention will be specifically described through exemplary embodiments. It should be understood, however, that elements, structures and characteristics of one embodiment may be beneficially incorporated in other embodiments without further recitation.

[0025] see figure 1 as well as Figure 4 ,Such as figure 1 with Figure 4 As shown, the lock 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 brake unit can drive the lock buckle to rotate, and the change of the lock buckle position can make the lock tongue fixed or loose in the lock buckle, so as to realize the locked or unlocked state. Wherein, the above-mentioned power mechanism 1 can be a motor, a spiral tube, etc., which is not limited here, as long ...

Abstract

Disclosed is a locking device, comprising a power mechanism (1), a connecting rod (3), a braking unit and a lock catch (5), wherein a power output end of the power mechanism (1) is connected to one end of the connecting rod (3), the other end of the connecting rod (3) is connected to the braking unit, and the braking unit drives the lock catch (5) to rotate; and the power mechanism (1) is connected to the connecting rod (3) via a gear so as to transmit the power of the power mechanism (1) to the connecting rod (3).

Description

technical field [0001] The invention relates to a lock, in particular to a locking device. Background technique [0002] When the door is in the closed state, the bolt installed on the door panel of the door lock enters the groove of the lock catch device. After the lock catch fixes the dead bolt, the most common thing in real life is to use a key to open it, that is, use a key to make the dead bolt Shrink back. However, after the electronically controlled locking device is installed, the lock catch of the locking device can also be released by energizing and opening, and the door can be pushed open even if the dead bolt does not shrink backward. [0003] However, the most common and insurmountable situation encountered by electric strikers is that due to the state of the door, a pre-load is applied to the lock. 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...
