Anti-jamming lifting base device

Abstract

The invention discloses an anti-jamming lifting base device. The device comprises a lifting track base and a lifting rod, wherein the lifting track base comprises a first track sleeve, a second track and a third track; a first through hole is formed in the top of the first track sleeve; four first fixed holes are formed around the first through hole; a locating block and a cover plate are arranged in the first track sleeve; a second through hole is formed in the central position of the cover plate; and four first fixed holes are formed around the second through hole. The device has the beneficial effects of effectively avoiding jamming due to angle deviation and increasing the percent of pass while facilitating operation and has the beneficial effects of easiness in transformation, low cost, and the like.

Description

technical field [0001] The invention relates to a seat body, in particular to a seat body that can be adjusted up and down. Background technique [0002] During the lifting adjustment process of the existing table, the height change and weight of the table are provided by the thread structure, and the lifting rail seat not only protects the internal thread structure and the purpose of aesthetics, but also has the auxiliary effect of stabilizing the lifting process. However, in actual processing During the process, the tightness of each component is not easy to control. For example, there is a gap between the rail sleeves of the lifting rail seat, and the spiral tube fixed by the rail sleeve at the bottom cannot reach a completely vertical state. Therefore, once the screw and the screw When the error of the position of the tube is not on the same vertical straight line, it will be stuck due to the angle deflection during the adjustment of the thread structure, so there have a...

[0002] During the lifting adjustment process of the existing table, the height change and weight of the table are provided by the thread structure, and the lifting rail seat not only protects the internal thread structure and the purpose of aesthetics, but also has the auxiliary effect of stabilizing the lifting process. However, in actual processing During the process, the tightness of each component is not easy to control. For example, there is a gap between the rail sleeves of the lifting rail seat, and the spiral tube fixed by the rail sleeve at the bottom cannot reach a completely vertical state. Therefore, once the screw and the screw When the error of the position of the tube is not on the same vertical straight line, it will be stuck due to the angle deflection during the adjustment of the thread structure, so there have always been problems such as difficult processing, high defective rate and extremely inconvenient operation in the future occur
