The invention discloses a cable movable support of a telescopic leg and a crane in the technical field of in-vehicle cable arrangement, and aims to solve the problem that in the prior art, when the telescopic leg stretches out and draws back, a cable in the telescopic leg is prone to fatigue and being damaged due to friction. According to the cable movable support of the telescopic leg and the crane, the cable movable support comprises a telescopic structure formed by connecting a plurality of telescopic units, each telescopic unit comprises a first structural arm and a second structural arm, and the first structural arm and the second structural arm are rotationally connected through a first shaft; the first shaft is connected with a buckle, and the buckle is used for connecting a cable; the telescopic structure is fixed to the fixed supporting leg and the movable supporting leg, and when the movable supporting leg drives the telescopic structure to stretch out and draw back, the first structural arm and the second structural arm rotate. The cable is prevented from being scratched during stretching and retracting through the structure of the telescopic unit, stretching and retracting are controlled at multiple positions of the cable through the multiple buckles, large curvature change of the cable is avoided, and then the sheath of the cable is protected in the stretching and retracting process of the cable along with the telescopic leg.

    本发明公开了一种车内电缆布置技术领域的伸缩腿的电缆活动支架及起重机,旨在解决现有技术中伸缩腿伸缩时内部的电缆容易疲劳和摩擦导致损坏的问题。本申请提供的伸缩腿的电缆活动支架及起重机,包括由多个伸缩单元连接构成的伸缩结构,伸缩单元包括第一结构臂和第二结构臂,第一结构臂和第二结构臂通过第一轴转动连接;第一轴与卡扣连接,卡扣用于连接电缆;伸缩结构分别固定于固定支腿和活动支腿,活动支腿驱动伸缩结构伸缩时,第一结构臂和第二结构臂发生转动。通过伸缩单元的结构避免电缆在伸缩时发生剐蹭,通过多个卡扣在电缆多个位置控制伸缩,避免了电缆发生较大幅度的曲率变化,进而在电缆伴随伸缩腿伸缩过程中保护了电缆的外皮。
