A dual-power lifting desktop

Abstract

Provided is a dual-powered raising / lowering desktop, comprising a desktop cover panel (1), a support system arranged on the lower end of the desktop cover panel (1), and a drive system used for driving a support assembly; said support system comprises a base (21) and a support assembly arranged between the base (21) and the desktop cover panel (1); the drive system comprises a drive assembly arranged at the middle of the desktop cover panel (1), a rotary shaft (31) in a bearing position and connected to the output end of the drive assembly, a traction component sleeved on the rotary shaft (31), and a traction steel cable (33) positioned on the desktop cover panel (1) by means of a rotary plate (32); the traction component drives the support assembly by means of the traction steel cable (33); in the dual-powered raising / lowering desktop, the traction steel cable (33) is used to drive the support assembly, simplifying the internal structure of the dual-powered raising / lowering desktop, reducing its cost and eliminating the mechanical wear and tear of its geared transmission, thereby reducing the driving force required and the noise produced.

Description

technical field [0001] The invention relates to the field of office furniture, in particular to a dual-power lifting desktop. Background technique [0002] With the development of society, office occupational diseases are on the rise. The height of traditional desks is constant, or the height can be customized during manufacture, but it is still difficult to change the height once it is delivered to use; office personnel work on the desk desktop at the same height for a long time, and it is very easy to cause waist, back, and so on. Occupational diseases of the neck or legs. Because these occupational diseases caused by sitting for a long time have plagued many workers, standing office or standing interactive office became popular in foreign countries at first. This kind of office has many benefits, especially it can solve the occurrence of some lumbar and cervical spondylosis, and it also has the effect of losing weight. According to research reports, this method can also...

Problems solved by technology

However, the transmission method of the traditional lifting table is to drive the supporting component (that is, the support fork) to open or retract through the lifting screw on one side, and the two sides of the lifting table are synchronously driven by the bevel gear and the linkage rod to make it rise and fall synchronously; but its disadvantages The advantage is that the transmission mechanism of this type of mechanical lifting table is complex, heavy, difficult to install and requires high transmission precision, which not only increases the production cost, but also increases the dead weight of the lifting table, which is difficult to carry and transport; in addition, the umbrella under this structure Tooth meshing transmission efficiency is low, resulting in a large transmission kinetic energy loss and an increase in transmission mechanical noise
