Description

Technical Field

[0001] The utility model belongs to the field of lifting teeth, in particular to a lifting tooth for a desk. Background Art

[0002] The lifting table can realize standing office. The automatic lifting table is generally powered by electricity. The height of the lifting table can be adjusted by controlling the mechanical device through the motor. The height of the lifting table can also be adjusted by controlling the air pressure rod or hydraulic rod through the compressor. Whether it is sitting or standing for a long time, it will have a bad physiological effect on the human body. Only sitting and standing alternately is the most scientific and healthy way of working. Sitting and standing alternately will lead to a great change in healthy office. However, as people sit and work for longer and longer periods of time, people gradually realize that sitting for a long time is not conducive to improving work efficiency. People begin to try sitting and standing alternately, and gradually lifting tables appear. Using lifting tables to stand and work has become a popular healthy way of working. The most important thing in the lifting table is the lifting table legs that can realize the lifting function. However, the existing lifting table legs are all equipped with a single gear and a single bearing, and the gears are horizontally meshed. Most of them are driven by motors, which are more worn during the lifting process. After long-term use, abnormal noises will occur, resulting in a low service life and poor stability.

[0003] Therefore, a lifting tooth of an office desk is proposed to solve the above-mentioned drawbacks. Utility Model Content
