Bookcase capable of ascending and descending quickly

Abstract

The invention discloses a bookcase capable of ascending and descending quickly. The bookcase comprises a bottom plate, and moving wheels are arranged on the lower surface of the bottom plate. The upper surface of the bottom plate is fixedly connected with a lifting bookcase. The lifting bookcase comprises a U-shaped frame and a motor, rotating holes are formed in the two sides, close to the top, of the U-shaped frame, rotating shafts are movably connected to the two sides through the rotating holes, the right end of one rotating shaft, at the right side, in the two rotating shaft is fixedly connected with the left end of an output shaft on the motor, and the left side of a fixed plate is fixedly connected with the right side of the U-shaped frame. According to the invention, the problems that in the actual use process, due to the fact that a chain can drive books in a whole bookshelf to rotate when rotating, the transmission friction force of the chain is relatively large, it is more strenuous to find the books, the books in the bookshelf are all exposed in the air, a large amount of dust is extremely prone to being accumulated on the surface of the books, the workload of book cleaning is increased, and meanwhile inconvenience is brought to readers are solved.

Description

technical field [0001] The invention relates to the technical field of bookcases, in particular to a rapidly lifting bookcase.

AI Technical Summary

Problems solved by technology

[0003] The purpose of the present invention is to provide a bookcase that can be lifted quickly, which improves the traditional device and solves the problem that in the actual use process, the chain will drive the books in the entire bookshelf when it rotates, and the transmission friction of the chain is relatively stronger. Larger, it will be more laborious to find books, and the books in the bookshelf are exposed to the air, and a large amount of dust is easy to accumulate on the surface, which increases the workload of book cleaning and also brings inconvenience to readers.
