The paddle includes an upper paddle and a lower paddle, which are respectively located on the upper and lower sides of the spring seat. Drive the paddle to rotate, and the paddle will no longer clamp the lock tongue, so that the lock tongue is no longer locked. When the door is pushed, due to the influence of external force, the lock tongue will automatically retract into the lock body, and it will be pushed back by the spring after the door is opened. In situ, but this structure is cumbersome and the stroke of the paddle is longer when unlocking, which means that the force required for unlocking is greater. If one of the slides is damaged, the entire lock body cannot be used and only There is a single dead bolt, and the anti-theft performance is poor.

Furthermore, the electronic door lock is installed on the door panel. When the square bar seat is in a static state, the dead bolt in the electronic door lock keeps protruding from the outer side of the housing and locked with the door frame. When the square bar seat rotates, it realizes driving The lock tongue, the lock tongue can be retracted to open the door panel, and the rotation of the square seat is realized by the handle. The common way is to turn the handle to realize the rotation of the square seat. When opening the door, you need to turn the handle first and then push and pull the door. It is inconvenient to open, and the door has a direction when opening, and some doors open inward. At this time, the handle needs to be pulled to drive the square seat to rotate and open the door. The change of the door is realized by a special internal structure, which requires a special lock. When changing the opening direction, the door lock needs to be replaced, which brings inconvenience to use and increases the cost of use.

Patent No.: CN107060498A announced the door-opening transmission mechanism of the push-pull electronic door lock. Although it solves the problem that the door can be opened directly after the handle is pulled to rotate the square seat, the panel of this design is not only bulky and loose in structure, but is only suitable for the area of the door panel. Larger doors, less versatility.

Patent No.: CN106837005A announced a push-pull electronic door lock reversing mechanism, which solves the problem of a push-pull electronic door lock that can be directly adapted to various opening door panels regardless of the direction of door opening, inside opening, left opening, and right opening. The reversing mechanism of the door lock, but this design still has a large panel of the reversing mechanism and a relatively loose mechanism, and the above two designs do not take into account the unlocking when the built-in power supply of the push-pull electronic door lock is out of power. After the power supply is out of power, the door lock will not be able to be opened, which causes great inconvenience to the user.
