The invention discloses a vehicle-mounted hidden telescopic ladder stand which comprises a ladder assembly, the ladder assembly is of a straight plate I-shaped ladder structure, ladder step limiting blocks are arranged at the bottom of the ladder assembly, are of a right trapezoid structure and are fixedly arranged on the two sides of the bottom of the ladder assembly through bolts, and ladder step handles are further arranged at the bottom of the ladder assembly. A single-side pulley combination is arranged at the top of the ladder assembly, an inner-layer sliding rail assembly is arranged on the outer side of the single-side pulley combination in a sleeving mode, a ladder roller combination is further arranged at the lower end of the inner-layer sliding rail assembly, and a ladder base plate is further arranged at the front end of the ladder roller combination, so that the telescopic ladder stand is locked firmly and reliably, noise is not generated in the whole vehicle running process, and releasing is convenient and fast. Due to the fact that the positioning safety pin is further arranged, accurate positioning can be achieved in the unfolded state, parts of all the parts do not shake, the safety insurance function is achieved in the initial state, double insurance is achieved through the safety insurance device and the locking device, and it is guaranteed that the crawling ladder cannot be automatically opened in the running process of the vehicle.
本发明公开了一种车载隐藏式伸缩爬梯,包括梯子总成,梯子总成为直板工字梯结构,梯子总成底部设置有梯步限位块,梯步限位块为直角梯形结构,通过螺栓固定设置在梯子总成底部的两侧,梯子总成底部还设置有梯步拉手,梯子总成顶部设置有单边滑轮组合,单边滑轮组合外侧套有内层滑轨总成,内层滑轨总成下端还设置有梯子滚轮组合,梯子滚轮组合的前端还设置有梯子垫板,使得伸缩爬梯锁定紧固、可靠,在整车行驶过程中不产生噪音,并且释放方便,快捷,由于还设置有定位安全销,可在展开状态实现精准定位,并且使各部位零件无晃动,在初始状态具有安全保险功能并与锁紧装置实现双保险,保证车辆在行驶中爬梯不会自行打开。
