Wherein: 1. the lock comprises a lock hook, a rotating shaft 2, a lock box 3, a sliding block 4, a protective cover 5, an anti-inserting plate 6, a landing door 7, a door frame 8 and a lock head 9.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

As shown in fig. 1, 2 a construction elevator layer door automatic mechanical lock, including latch hook 1, pivot 2, slider 4 and lock box 3, latch hook 1 is the zigzag mechanism, and latch hook 1 is connected to layer door 7 through pivot 2, fixed connection between latch hook 1 and the pivot 2, and pivot 2 is rotatable to be connected with layer door 7, and the tail end department of latch hook 1 is equipped with slider 4 that can slide from top to bottom, and slider 4 is connected with layer door 7, and the front end department of latch hook 1 is equipped with lock box 3, and lock box 3 connects on door frame 8, is equipped with on lock box 8 with latch hook 1 complex lockhole.

In the technical scheme, a protective cover 5 for protection is arranged outside the lock hook 1, the rotating shaft 2 and the sliding block 4, and the protective cover 5 is connected with the landing door 7 through bolts. The protective cover 5 integrally surrounds and protects the lock hook 1 and the sliding block 4, and only the side surface of the lock box 3 and the surface mounted with the landing door 7 are reserved.

In the above technical scheme, the outward end of the rotating shaft 2 is provided with a polygonal lock head 9, and the protective cover 5 is provided with a hole corresponding to the lock head 9. In this embodiment, the lock head 9 adopts a regular triangle structure.

In the technical scheme, the anti-inserting plate 6 for preventing the thin plate from being inserted to influence the door locking function is arranged beside the lock hole of the lock box 3.

As shown in fig. 3 and 4, the lock hook 1 and the rotating shaft 2 are installed on the landing door 7 and can freely rotate around the rotating shaft 2, the sliding block 4 is installed on the landing door 7 beside the lock hook 1, the protective cover 5 is installed on the landing door 7 to completely shield the lock hook 1 and the sliding block 4, and the lock box 3 is installed on the door frame 8.

The working principle is shown in fig. 5, when the landing door 7 is closed, the lock hook 1 and the rotating shaft 2 insert the hook part of the lock hook 1 into the lock box 3 under the action of self weight, and the landing door 7 cannot be opened upwards, so that the automatic locking function is realized; when the matched cage door is opened, the cage door can drive the sliding block 4 to slide upwards, the sliding block 4 pushes the lock hook 1 to rotate reversely, the hook part of the lock hook 1 exits the lock box 3, and the landing door 7 can be opened upwards, so that the automatic unlocking function is realized.

The rotating shaft 2 and the lock hook 1 are rotated through the triangular key, the hook part of the lock hook 1 can be withdrawn from the lock box 3, and therefore the triangular key unlocking function is achieved.

The above description is only for the preferred embodiment of the present invention, but the scope of the present invention is not limited thereto, and any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope of the present invention should be covered by the present invention.
