Lifting cabinet and four-thread synchronous retraction device for same

Abstract

The invention provides a lifting cabinet and a four-thread synchronous retraction device for the lifting cabinet, used for solving the problem that for the existing lifting cabinet, a plurality of winders are needed for rolling lifting ropes, so that the synchronism is low. The key points of the technical scheme are as follows: the lifting cabinet comprises a mounting plate, as well as a winding reel, a motor and guiding mechanisms which are mounted on the mounting plate, wherein the winding reel is fixedly connected with an output shaft of the motor, a winding groove is arranged in the winding reel, the winding groove comprises two winding sections which are connected, two fixing parts used for fixing lifting ropes are arranged in each winding section, the guiding mechanisms are in one-to-one correspondence with the winding sections, the two guide mechanisms guide the lifting ropes in the different winding sections to two opposite sides of the mounting plate, and the two lifting ropesin the same winding section are guided to the same side of the mounting plate. When the lifting ropes are rolled, the winding reel rotates under the output of the motor, the four lifting ropes are rolled synchronously, meanwhile, under the effect of the guiding mechanisms, the lifting ropes are guided to the two sides of the mounting plate and are in the drooping state, thus the synchronous retraction of the four lifting ropes is realized, and therefore, the operation is more stable when the lifting ropes on which heavy objects are hung are lifted.

Description

Technical field [0001] The invention relates to the field of lifting cabinets, in particular to a lifting cabinet and a four-wire synchronous retracting device thereof. Background technique [0002] Lifting cabinet is a kind of storage cabinet that can be lifted and stored. Usually, the lifting cabinet is installed in a higher space. When in use, the inner cabinet with items is lowered. When not in use, the inner cabinet is stowed up. Effective and reasonable use of height space. In the prior art, a lifting cabinet usually includes an outer cabinet and a liftable inner cabinet. A lifting device is installed on the top of the outer cabinet. The lifting device includes a lifting rope connected to the inner cabinet. The existing lifting cabinet uses four The lifting rope is used to lift the lifting cabinet, but multiple reels are required to rewind, which takes up a lot of space and is prone to problems that the lifting cabinet is not smoothly lifted due to the inconsistency of mul...

AI Technical Summary

Problems solved by technology

In the prior art, the lifting cabinet usually includes an outer cabinet body and a liftable inner cabinet body. A lifting device is installed on the top of the outer cabinet body. The lifting device includes a sling connected to the inner cabinet body. The existing lifting cabinet uses four The lifting rope is used to lift the lifting cabinet, but multiple wire reels are required to rewind it, which takes up a lot of space, and it is prone to the problem that the lifting cabinet is not stable due to inconsistent retraction and release of multiple lifting ropes
