Pneumatic lifting table frame and lifting table

Abstract

The invention discloses a pneumatic lifting table frame and a lifting table. The invention belongs to the field of lifting mechanisms. The lifting table frame comprises a cross beam and stand columns.The lifting table frame further comprises a pressure sensor for detecting the load of the lifting table frame, a controller for receiving signals of the pressure sensor and an adjustable air spring assembly for driving the stand columns to ascend and descend. The adjustable air spring assembly comprises an adjustable air spring body, an air storage tank, a piston rod assembly and a driving piece.The adjustable air spring body is connected with the air storage tank through an air pipe. The controller controls the driving piece. The adjustable air spring body is arranged in one stand column. The driving piece drives the piston rod assembly to do piston motion in the air storage tank. The lifting table frame is high in safety, easy to lift, good in comfort degree, low in damage rate, long in service life, high in stability and high in practicability.

Description

【Technical field】 [0001] The invention relates to the field of lifting mechanisms, in particular to a pneumatic lifting table frame and a lifting table. 【Background technique】 [0002] Desks are indispensable for daily life and office supplies. The height of traditional desks is fixed and cannot be adjusted according to the user's personal situation and actual needs. In terms of diseases, the height-adjustable lifting table can be adjusted according to the user's different body height and other conditions to improve comfort and relieve pain. The driving mode of the currently used lifting table is generally manual or electric, and the manual lifting table is laborious. When the load is too heavy, it is easy to cause deformation and damage to the handle and transmission components. The electric lifting table must be installed in an area with a power socket, and it needs to consume more power when used, resulting in energy waste. At the same time, the noise of the motor and dri...

[0002] Desks are indispensable for daily life and office supplies. The height of traditional desks is fixed and cannot be adjusted according to the user's personal situation and actual needs. In terms of diseases, the height-adjustable lifting table can be adjusted according to the user's different body height and other conditions to improve comfort and relieve pain. The driving mode of the currently used lifting table is generally manual or electric, and the manual lifting table is laborious. When the load is too heavy, it is easy to cause deformation and damage to the handle and transmission components. The electric lifting table must be installed in an area with a power socket, and it needs to consume more power when used, resulting in energy waste. At the same time, the noise of the motor and drive system is too large, and the failure rate High, high cost, the pneumatic lifting table is more and more favored by consumers because of its low cost and low noise. The power source of the pneumatic lifting table is a pneumatic spring. The lifting speed of the table is unstable. If the table load is too large, it will be difficult to rise. If the table load is small, the speed will be too fast, causing damage to people or things around you.
