The invention discloses a telescopic wall leaning wheel which comprises a guide frame, a telescopic rod and a contact wheel. Guide wheels and a ratchet wheel are arranged on the guide frame, the telescopic rod is arranged in the guide frame in a penetrating mode and is limited and guided by the guide wheels, a rack is arranged on the telescopic rod in the length direction, the rack and the ratchet wheel are in matched transmission, an anti-reversing pawl acting on the ratchet wheel is arranged on one side of the ratchet wheel, and the contact wheel is mounted at the outer end part of the telescopic rod. The telescopic wall leaning wheel is limited by the guide wheels, the ratchet wheel drives the rack to enable the contact wheel to stretch out and draw back, stepless adjustment of the telescopic distance can be achieved, limitation of a positioning hole and the like is avoided, the telescopic wall leaning wheel can be better matched with a concave vertical face, and the stability of a platform can be easily improved; and in addition, the ratchet wheel can be locked after stretching out in place through the anti-reversing pawl, a positioning structure does not need to be additionally arranged, the unlocking operation is very simple, use is convenient, and the cost is low.

    本发明公开了一种伸缩靠墙轮,包括导向架、伸缩杆和接触轮,导向架上设置有导向轮和棘轮,伸缩杆穿设于导向架中,并由导向轮限位导向,伸缩杆上沿长度方向设置有齿条,齿条与棘轮配合传动,棘轮的一侧设置有作用于棘轮的防倒退棘爪,接触轮安装于伸缩杆的外端部。上述伸缩靠墙轮依靠导向轮限位并通过棘轮传动齿条使得接触轮伸缩动作,可实现无极调节伸缩距离,不受定位孔等限制,以更好地适配凹立面,便于提高平台的稳定性,另外防倒退棘爪可实现接触轮伸出到位后即锁定,无需再另外增加定位结构,解锁操作也很简单,使用方便,成本低。
