Elastic expansion module and lifting device using the same

Abstract

The invention relates to an elastic telescopic module and a lifting device using the module. The lifting device comprises a base, a bracket is arranged on the base, an elastic expansion module is arranged on the bracket, and the elastic expansion module is connected with an adapter. Wherein, the elastic telescopic module includes a first frame body, the inside of the first frame body has a first accommodating space for positioning a first constant force spring, and the inside of the second frame body has a second accommodating space for positioning A second constant force spring. The top end of the second frame body is located below the bottom end of the first frame body. The second accommodating space is fixed on the top of the first frame body, so that the first constant force spring and the second constant force spring are alternately covered, so that the first frame body and the second frame body can move in opposite directions.

Description

technical field [0001] The present invention relates to an elastic telescopic module and a lifting device using the module, especially a device mounted on the rear side of a display, which can make the structure lighter and thinner, prolong the service life of the product, and increase the lifting stroke of the display. Lifting device. Background technique [0002] In addition to adjusting the elevation angle of traditional monitors, most of them add a lifting device to adjust the height, so as to meet the needs of users of different sizes. The general lifting device mainly uses the relative movement of the fixed slide rail and the movable slide rail with fixed specifications to raise or lower the display, and use at least a certain force spring as a source of resilience. In actual use, it is only through the stretching and positioning of a single constant force spring. Since all the supporting force is borne by the constant force spring, the overall volume of the constant ...

AI Technical Summary

Problems solved by technology

[0005] The object of the present invention is to provide an elastic telescopic module and a lifting device using the module, which can solve the problem that the lifting device in the prior art only relies on the stretching and positioning of a single constant force spring, which makes the lifting device limited by the fixed position. The size of the force spring causes the overall volume to be too large and cannot be effectively thinned, and makes the single constant force spring evenly share all the up and down lifting support forces, resulting in shortened service life. It is modular and thinner to meet the use and installation requirements of smaller constant force springs, which is convenient for manufacturing and assembly, and can meet the overall thinner appearance requirements and avoid occupying space
