Technical Field

The invention relates to the field of elevator manufacturing, in particular to an automatic lock catch of an ultrathin elevator lock.

Background

With the rapid development of science and technology, the requirements of elevators are stricter and stricter, the space reserved for the call box by the elevator is smaller and smaller, and therefore the lock installed in the call box is also smaller and smaller. The existing elevator lock catch has the disadvantages of complex structure, large occupied volume and unreasonable design, and can not meet the development trend of the existing elevator.

Disclosure of Invention

The invention provides an automatic lock catch of an ultrathin elevator lock, which aims to solve the technical problems that the existing elevator lock catch is complex in structure, large in occupied volume and unreasonable in design and cannot meet the development trend of the existing elevator.

The technical scheme adopted by the invention for solving the technical problems is as follows: the automatic lock catch of the ultrathin elevator lock comprises a crank arm ratchet wheel, a lock column and a linkage assembly, wherein the linkage assembly is communicated with the crank arm ratchet wheel, and the linkage assembly can drive the crank arm ratchet wheel to be clamped on the lock column.

Further: the crank arm ratchet wheel is rotatably installed on the fixed lock shell, a notch with an opening at the right side is formed in the upper portion of the crank arm ratchet wheel, clamping teeth are arranged on the left side of the crank arm ratchet wheel, and the clamping teeth and the rotating center of the crank arm ratchet wheel are coaxially arranged.

Further: the linkage mechanism comprises a limiting wrench, a torsional spring, a guide rod and a guide sleeve, wherein the limiting wrench is rotatably installed in the lock shell, the right arm of the limiting wrench is clamped in the clamping teeth, the torsional spring is installed at the rotating joint of the limiting wrench and the lock shell, the deformation force of the torsional spring can prevent the limiting wrench from rotating anticlockwise, the left part of the guide rod is fixedly connected with the upper arm of the limiting wrench, the guide sleeve is installed in the lock shell, and the guide sleeve is inserted into the guide sleeve and can slide along the horizontal direction.

The automatic lock catch of the ultrathin elevator lock has the advantages that through the arrangement of the crank arm ratchet wheel and the limiting wrench, compared with the lock catch in the prior art, the structure is more compact, the space utilization rate is higher, the space of a lock body is saved, meanwhile, the right arm of the limiting wrench is clamped in the clamping teeth of the crank arm ratchet wheel, the locking effect can be prevented from being influenced by the free rotation of the crank arm ratchet wheel, meanwhile, the arrangement of the clamping teeth enables the crank arm ratchet wheel to have a plurality of clamping positions, and the practicability is strong.

Drawings

The invention is further illustrated with reference to the following figures and examples.

Fig. 1 is a schematic structural view of an automatic shackle of an ultra-thin elevator lock according to the present invention.

In the figure, the device comprises a crank arm ratchet wheel 1, a lock column 2, a lock shell 3, a lock shell 4, a notch 5, a latch 6, a limit spanner 7, a torsion spring 8, a guide rod 9 and a guide sleeve.
