Description

Technical Field

[0001] The utility model relates to a mechanical interlocking structure, which is mainly used for interlocking and fixing a lifting door of a cage to improve the use safety of the cage. Background Art

[0002] The cage refers to a cage-shaped device used to transport people up and down on an elevator. To improve operational safety, most existing cage bottom plates are equipped with a mechanical interlocking mechanism for interlocking the cage door. The hook plate provided on the cage door is fixed by a locking mechanism provided on the cage bottom plate. When the cage door needs to be opened, the locking mechanism of the mechanical interlocking mechanism is manually opened to release the hook plate, that is, to release the fixation of the cage door. After the cage door is opened, the control of the locking mechanism of the mechanical interlocking mechanism is released.

[0003] It often happens during manual operation that the control of the locking mechanism is released when the hook plate has not completely left the locking mechanism of the mechanical interlocking mechanism, which can easily cause the hook plate to be locked again, causing the cage door to reset again, thereby greatly increasing the probability of the operator being pinched by the cage door.

[0004] Therefore, the research purpose of the utility model is to design a mechanical interlocking structure that can automatically form a fixed limit for the locking mechanism after opening, and reset the locking mechanism after the cage door is fully opened, thereby ensuring that the cage door can be fully opened to improve the safety of use.
