Abstract

The invention provides a stepless adjustable stretching/retracting device. The device comprises a first support, a second support and at least one folding arm; each of the at least one folding arm comprises a first quadrangular structure and a second quadrangular structure, wherein the first end of the first quadrangular structure is rotationally connected with the first support, the first end ofthe second quadrangular structure is rotationally connected with the second support, and the second end of the first quadrangular structure is rotationally connected with the second end of the secondquadrangular structure through a rotational connection device; and each of the at least one folding arm further comprises a power supporting device, wherein the power supporting device is connected with the corresponding first quadrangular structure to form a triangular structure, and the power supporting device provides power to drive the corresponding first quadrangular structure to rotate, so that the corresponding first quadrangular structure drives the corresponding second quadrangular structure to rotate synchronously. The stepless adjustable stretching/retracting device has a small influence range on surroundings, occupies a small space area and has a large stretching/retracting amplitude, and therefore the convenience and practicability of the stepless adjustable stretching/retracting device in use are greatly improved.

Description

technical field [0001] The invention relates to the technical field of machinery, in particular to a steplessly adjustable telescopic device. Background technique [0002] In recent years, with the development and popularization of computer technology, more and more people use computers to work or study. In order to better maintain the correct office posture and prevent modern occupational diseases, adjustable desks have appeared on the market to meet people's needs for office height adjustment. [0003] At present, the small and medium-sized lifting tables on the market are usually lifted by a single arm. During the lifting process, the desktop will have obvious front and rear or left and right displacements, which will have a large impact on the surrounding area. Moreover, the small and medium-sized lifting tables still have the problem of insufficient lifting height. Contents of the invention [0004] The present invention aims to solve the problems described above. I...
