The invention is applicable to the field of telescopic structures, and provides a multi-stage telescopic rod which comprises cylinders with at least two sizes and sliding seats with at least two sizes. One sliding seat with a matched size and a cylinder with a small size are arranged in a cylinder with a large size; and in addition, the sliding seat located in the large cylinder is fixedly connected with the small cylinder. On the inner wall of each cylinder, a plurality of sliding rods distributed at intervals are fixed along a circumferential direction of the cylinder, rolling wheels are arranged on at least two opposite side surfaces on each sliding seat and are in rolling fit with the sliding rods on the outer sides of the rolling wheels, and the rolling wheels can roll along the sliding rods. According to the multi-stage telescopic rod provided by the invention, a multi-stage telescopic structure adopts a structure characterized by sleeving a telescopic arm by a telescopic arm, the integration is realized, and the product is attractive in appearance and structure and occupies a small space. In addition, a longer stroke is realized, and meanwhile, the problems of shaking and deflecting caused by a long force arm can be effectively solved.
Description
technical field [0001] The invention belongs to the field of telescopic structures, in particular to a multi-stage telescopic rod. Background technique [0002] In the case of limited space and strict requirements on the appearance, and the movement stroke is relatively large, the multi-stage telescopic structure is the most ideal choice. At present, the multi-stage telescopic structure is basically an external superimposed structure. The movement range is achieved, but the appearance is not beautiful, there is no sense of unity, and the space is relatively large, so it is not suitable for occasions with limited space. Contents of the invention [0003] The purpose of the present invention is to provide a multi-stage telescopic rod, aiming to solve the problems of unattractive appearance and large space occupation of the multi-stage telescopic structure in the prior art. [0004] The present invention is achieved in this way, a multi-stage telescopic rod, including cylind...
