The utility model relates to the field of vehicle braking systems, in particular to a subway folding type on-vehicle air braking isolation handle which solves the problems that an existing handle is of an unfoldable straight structure and can only rotate on the horizontal plane, and when the handle is in an isolation state, the tail of the handle protrudes out of the vertical plane of a built-in side wall plate, and the side wall plate needs to be designed to contain the handle. The wall plate fixing device comprises a fixing base, and the fixing base is fixedly connected with a brake isolation valve. The handle is rotationally connected with the fixed seat through a pin shaft; a spring mechanism is further arranged in the handle, and the spring mechanism in the handle is used for keepingthe handle and the fixing base in a fit state all the time. According to the handle, the movement freedom degree of the handle in the vertical plane is increased while it is guaranteed that the original handle has the unchanged rotation movement freedom degree in the horizontal direction, when the handle is in the isolated state, the handle can be folded to be perpendicular to the rail surface andhidden between the built-in side wall plate and the vehicle side wall, and the overall effect of vehicle built-in installation is not affected.
地铁折叠式车上空气制动隔离手柄,涉及车辆制动系统领域,解决现有手柄为不可折叠的平直结构,且只能在水平面转动,当手柄处于隔离状态位时,手柄尾部凸出内装侧墙板的竖直平面,需要对侧墙板设计进而容纳手柄,导致墙板整体效果差等问题,包括固定座,所述固定座与制动隔离阀固定连接;手柄,手柄与固定座通过销轴转动连接;其中,手柄内部还设有弹簧机构,手柄内部的弹簧机构用于保持使手柄与固定座时刻处于贴合状态。本发明的手柄在保证原手柄在水平方向具备旋转运动自由度不变的同时,增加手柄在竖直平面的运动自由度,当手柄处于隔离状态位时,可将手柄折叠至与轨面垂直状态,隐藏至内装侧墙板与车辆侧墙之间,不影响车辆内装的整体效果。
