Abstract

The invention belongs to the technical field of electric push rods, and particularly relates to a multi-section electric push rod which comprises a first-stage rod group, a second-stage rod group anda third-stage rod group. The driving end of the first-stage rod group is connected with the driving end of the second-stage rod group, the first-stage rod group drives the driving end of the second-stage rod group to rotate and enables the second-stage rod group to move in the length direction of the first-stage rod group, and the driving end of the second-stage rod group is connected with the third-stage rod group and drives the third-stage rod group to move in the length direction of the second-stage rod group. When the first-stage rod group drives the second-stage rod group to move in the length direction of the first-stage rod group in a telescopic mode in use, the driving end of the second-stage rod group is also driven to rotate so that the second-stage rod group drives the third-stage rod group to move in the length direction of the second-stage rod group in a telescopic mode simultaneously, the first-stage rod group can drive the second-stage rod group and the third-stage rod group to move in a telescopic mode simultaneously, the stretching or shortening efficiency of the multi-section electric push rod is greatly improved, the structure is small, and the multi-section electric push rod is suitable for furniture and household appliance industries.

Description

technical field [0001] The invention belongs to the technical field of electric push rods, in particular to a multi-section electric push rod. Background technique [0002] An electric push rod is a linear drive device that converts the rotational motion of a drive motor into a linear movement of the push rod. Existing electric push rods are generally single-section electric push rods. When a relatively large stroke is required, the overall size of the single-section push rod needs to be relatively large, resulting in that it cannot be installed in a small installation space. In response to this situation, the existing electric push rod is also designed to be multi-section telescopic, so as to ensure a relatively small space under the premise of a large stroke. However, the existing multi-section electric push rod has a complex structure and is difficult to stretch low efficiency. Contents of the invention [0003] The object of the present invention is to provide a mult...
