The vertical hinged door is a most common door opening mode in the present life, and the principle is that a door body is hinged on a door post, so that the door body can rotate around the door post, and then the door is opened and closed by providing a driving force through a door opener. According to the principle, one end of the vertical hinged door is in a free state similar to a cantilever structure and is easy to push, in order to limit the free state of the tail end of the vertical hinged door, a bolt lock is generally arranged at the bottom of the tail end of the vertical hinged door, and after the door body is closed, the bolt is inserted into a base hole or directly inserted into the ground to lock the door body. The scheme can only limit the movement of the tail end of the vertical hinged door, and manual operation is needed for opening and closing the door every time, so that the scheme is very inconvenient.
In the existing electric latch lock, the stroke of the latch is generally not adjustable after being set, when stones or other obstacles on the ground are encountered in the locking process, the motor is blocked, sediment, stones or other objects can be inevitably entered into a base hole on the ground, and the motor can be damaged due to frequent blocking. Secondly, after long-term use, the cantilever end of the door body can deform due to the dead weight of the door body, so that the tail end of the door body sinks, and the door can be closed seriously. In addition, the bolt lock mostly does not have a self-locking function, and after normal locking, the bolt can be pried off and unlocked by a tool, so that the safety is low.
