Embodiment 1

[0058] Such as figure 1 , 2 , 9-12 shown.

[0059] A single power source hydraulic auxiliary synchronous lift table, which includes a desktop 1, two hydraulically driven lifting legs 2, and a pneumatic (hydraulic) dynamic telescopic rod or pneumatic (mechanical) tension and compression spring mechanism 7 as a driving lifting leg 2 follow-up power source legs 3 and base 4, such as figure 1 , 2 As shown, the lifting leg 2 is composed of a hydraulic cylinder and a piston rod. The rod chamber of the first hydraulic cylinder communicates with the rodless chamber of the second hydraulic cylinder through a flexible hydraulic tube 6, and the rod chamber of the second hydraulic cylinder The rod chamber communicates with the rodless chamber of the first hydraulic cylinder through the flexible hydraulic tube 6; when the power source leg 3 rises ( figure 2 ) or drop ( figure 1 ) drives the desktop 1 to rise or fall, and the rise or fall of the desktop 1 drives the piston rods of eac...

Embodiment 2

[0065] Such as image 3 , 4 shown.

[0066] The difference between this embodiment and Embodiment 1 is that as the power source leg 3 that drives the lifting leg 2 to go up and down, a separate hand crank lifting mechanism, a foot pedal lifting mechanism or a human mechanical power transmission mechanism 8, a hand rocker lifting mechanism, Pedal elevating mechanism or manpower mechanical force transmission mechanism 8 can adopt the same structure as adopting on the existing lifting table. The rest are all the same as in Example 1.

Embodiment 3

[0068] Such as Figure 5-6 shown.

[0069] The difference between this embodiment and Embodiment 1 is that as the power source leg 3 that drives the lifting leg 2 to lift, it adopts a separate motor lifting mechanism or a motor force transmission mechanism 9, and the motor lifting mechanism or motor force transmission mechanism 9 is the same as the existing lifting table. The structure adopted above is identical, all adopts motor 10 as power source. The rest are all the same as in Example 1.

Abstract

A single-power-source hydraulic auxiliary synchronous lifting table is characterized by comprising a table top (1), at least two hydraulic-driven lifting legs (2) and a power source leg (3) used for driving the lifting legs to follow up; each lifting leg (2) is composed of a hydraulic cylinder and a piston rod, a rod cavity of the first hydraulic cylinder is communicated with a rodless cavity of the second hydraulic cylinder, a rod cavity of the second hydraulic cylinder is communicated with a rodless cavity of the third hydraulic cylinder, a rod cavity of the third hydraulic cylinder is communicated with a rodless cavity of the fourth hydraulic cylinder, in the same way, a rod cavity of the last hydraulic cylinder is communicated with a rodless cavity of the first hydraulic cylinder. Whenthe power source leg ascends or descends, the table top (1) is driven to ascend or descend; the table top (1) ascends or descends to drive the piston rods of the hydraulic cylinders to extend or contract, so that the lifting legs (2) synchronously ascend or descend. The lifting table is simple in structure, low in cost, convenient to manufacture and good in multi-table-leg synchronous lifting performance.

Description

technical field [0001] The present invention relates to a kind of furniture, especially a desk that can be raised and lowered, specifically a single power source hydraulic auxiliary synchronous lift desk. Background technique [0002] People use various desks when they are working and studying. It is easy to cause cervical spine, lumbar spondylosis and other diseases when using ordinary traditional desks for a long time to sit and work and study. Properly changing the posture of standing and using desks can effectively prevent cervical spine. Spondylosis, lumbar disease, etc. Scientific research shows that the harm of sitting for a long time is even greater than the harm caused by smoking, and insisting on standing for a long time can consume a certain amount of extra calories, maintain body shape and weight, and help the overall health of the body. In order to suit users of different body heights, the existing lifting desks have been designed with various manual, double or ...
