Description

technical field

The invention relates to the technical field of laboratory equipment, in particular to a micro-vibration double-layer intelligent instrument table that can be remotely controlled to lift.

Background technique

With the country's continuous emphasis on scientific research, many laboratories have accelerated the pace of hardware equipment construction, but the laboratory site and space are difficult to meet actual needs. In addition, office occupational diseases are on the rise, which has a lot to do with people sitting for a long time at work. Sitting for a long time will increase the probability of cardiovascular load, waist and neck pain, obesity and other diseases. The height of the traditional desktop remains basically fixed, which cannot meet the most basic physical coordination needs. Therefore, the liftable and three-dimensional design of the experimental table is more important.

Lifting tables that can be adjusted in height according to actual needs can be divided into two types: manual adjustment and electric adjustment from the principle of braking. Chinese patent 201510791931.2 proposes a manual lifting table, which realizes desktop braking and height adjustment through the transmission bin and lifting pulley assembly; the lifting table proposed in Chinese patent 201621132303.X, the operator controls the handle, uses the hole pin to cooperate with the component and reset The spring realizes the adjustment of the height of the desktop; Chinese patent 201710130008.3 proposes a lifting desk, which uses an electric push rod as a part of the X-shaped support frame to provide power for the overall lifting; Chinese patent 201520103957.9 proposes a lifting desk, which is controlled by a clutch Steel ropes and rollers drive the main table to move up and down.

The existing lift tables are basically single-layer structures, and the manual lift tables have limited lifting gears, and the operation will consume a lot of time and energy. In the case of instruments on the table, the manual lift tables are mostly unusable or have certain risks. However, the structure of the existing electric lifting table is cumbersome and requires frequent maintenance. The desktop area is fixed, and the strength and material cannot meet the needs of the laboratory.
