The cable built-in type electric lifting stand column comprises a telescopic sleeve and a transmission assembly arranged in the telescopic sleeve, the transmission assembly drives the telescopic sleeve to stretch out and draw back, the telescopic sleeve comprises an inner pipe, a middle pipe and an outer pipe which are sequentially connected in a sleeved mode from inside to outside, and a cable penetrates through the interior of the telescopic sleeve to be arranged. The cable comprises guiding sections guided by the guiding piece, a positioning section positioned by the positioning piece and free sections, the two ends of the positioning section are connected with the two guiding sections through the free sections respectively, and the two guiding sections are connected with the upper end and the lower end of the electric lifting stand column respectively. The cable is pulled by the upper end of the electric lifting stand column to achieve length take-up and pay-off in the telescopic sleeve, and in the take-up and pay-off process of the cable, the positioning section is positioned by the positioning piece so as to limit the positioning section from moving towards the end of the middle pipe. According to the electric lifting stand column, the cables can be effectively prevented from being stacked and extruded, so that the phenomenon that the cables are damaged due to extrusion is avoided, and then the risks of short circuit, electric leakage and the like are reduced.
本发明公开了一种线缆内置式电动升降立柱,包括伸缩套管和设于伸缩套管内的传动总成,传动总成驱动伸缩套管伸缩,所述伸缩套管包括由内而外依次套接的内管、中管和外管,线缆贯穿伸缩套管内部设置,所述线缆包括被引导件引导的引导段、被定位件定位的定位段、以及自由段,所述定位段的两端分别通过自由段与两个引导段连接,两个引导段分别与电动升降立柱的上端和下端连接,所述线缆在电动升降立柱上端拉动下实现在伸缩套管内的长度收放,所述线缆收放过程中,所述定位段被定位件定位以限制其向中管的端部移动。本发明的电动升降立柱,能够有效避免线缆发生堆积挤压,由此避免了线缆因挤压而发生破损的现象,进而降低短路和漏电等风险。
