Mechanical lifting table and lifting adjusting method

Abstract

The invention discloses a mechanical lifting table and a lifting adjusting method. The lifting table comprises a table top, a table case and two table legs; each table leg comprises a fixing leg and a lifting leg which is mounted on the fixing leg and can go up and down; the table case and / or the table top are / is fixed to the top end of each lifting leg; a left-right synchronous telescopic mechanism is mounted in the table case, the left end and right end of the left-right synchronous telescopic mechanism are connected with the corresponding lifting leg through symmetrically arranged lifting leg lifting mechanisms; the left-right synchronous telescopic mechanism comprises a vertically arranged first wheel shaft which is mounted in the table case, a gear which is fixedly mounted on the first wheel shaft, and two racks which are meshed with the gear in a transmission mode, wherein of the two racks which are arranged in the length direction of the table case, one is connected with one of the two lifting leg lifting mechanisms, and the other one is connected with the other one of the two lifting leg lifting mechanisms; a drive mechanism which drives the gear to rotate horizontally is further mounted in the table case; guide rails are arranged between the lifting legs and the fixing legs. The mechanical lifting table needs no motor and is convenient to adjust, good in synchronicity and high in adaptability.

Description

technical field [0001] The invention relates to a mechanical lift table and a lift adjustment method, belonging to the field of lift tables. Background technique [0002] With the development of society and the advancement of science and technology, the requirements for desks and chairs in modern offices have changed from simply meeting the requirements of office work to comfortable and healthy office work. The height of the traditional desk cannot be adjusted in time according to the height of the office staff and the working status of the office staff, so there is an urgent need for a desk that can automatically adjust the height according to the height of the office staff, office habits and work status. [0003] Although there have been electric height-adjustable desks on the market, because the electric adjustable desk needs an external power supply, it is inconvenient to use and move. There are also mechanical height-adjustable desks on the market, but basically there ...

AI Technical Summary

Problems solved by technology

The height of the traditional desk cannot be adjusted in time according to the height of the office staff and the office status of the office staff, so there is an urgent need for a desk that can automatically adjust the height according to the height of the office staff, office habits and office status

[0003] Although electric height-adjustable desks have appeared on the market, because electric adjustable desks require an external power supply, it is inconvenient to use and move

There are also mechanical height-adjustable desks on the market, but basically there is a problem of poor synchronization of the legs when lifting and lowering, which often leads to the problem that the two table legs cannot be synchronized
