The invention relates to the technical field of subway accessories, and discloses a subway pull ring capable of being changed into a rigid member. The subway pull ring comprises a subway cross rod, the outer surface of the subway cross rod is fixedly sleeved with a fixing sleeve, the bottom of the fixing sleeve is fixedly connected with a connecting rod, the bottom of the connecting rod is fixedlyconnected with a connecting ball, the outer side of the connecting ball is movably connected with a ball sleeve, the bottom of the ball sleeve fixedly communicates with a hollow pipe, and the bottomof the hollow pipe is fixedly connected with a pull ring shell. A passenger holds the pull ring seat; when the motor rotates, the motor moves downwards; meanwhile, the pull ring seat slides the sliding seat downwards through the guide rope; the four swinging arms on the outer side of the sliding seat expand outwards; therefore, the bottom plate is pushed outwards, the friction plate on the surfaceof the bottom plate can be attached to the inner wall of the ball sleeve, the friction teeth on the friction plate can be matched with the friction limiting grooves in the ball sleeve, friction forceis increased, it is guaranteed that the ball sleeve and the connecting ball are mutually fixed, it is guaranteed that the subway pull ring can be stressed to become rigid, and passengers are prevented from moving.
本发明涉及地铁附件技术领域,且公开了一种可变化成刚性的地铁拉环,包括地铁横杆,所述地铁横杆的外表面固定套装有固定套,固定套的底部固定连接有连接杆,连接杆的底部固定连接有连接球,连接球的外侧活动连接有球套,球套的底部固定连通有空心管,空心管的底部固定连接有拉环外壳。乘客握住拉环座时,会使其向下位移,同时拉环座通过引导绳将滑座向下滑动,而滑座外侧的四个摆动臂就会向外扩张,从而将底板向外推动,底板表面的摩擦片就会与球套的内壁相互贴合,其中摩擦片上的摩擦齿会与球套内部上的摩擦限槽相互契合,增加摩擦力,从而保证了球套与连接球相互固定住,从而确保地铁拉环受力可变成刚性,防止乘客的耸动。
