The invention discloses an angle detection type anti-overwinding switch, and belongs to the technical field of lifting appliance hoisting equipment, the angle detection type anti-overwinding switch comprises a shell, a signal output cable is arranged on one side of the upper end of the shell, an angle detection module is arranged at one end in the shell, a sealing gasket is arranged at the lower end of the shell, and a pull rod is arranged in the sealing gasket. When the cover plate is installed, the vertical rods drive the transverse rods to move in the fixing frame, the transverse rods move to drive the sliding plates to move in the fixing frame, the second spring is compressed, then the cover plate is installed at the front end of the shell, meanwhile, the folded plates at the two ends of the cover plate are inserted into the fixing frame through the inserting holes, and the vertical rods are loosened; a second spring elastically stretches to push a plurality of clamping blocks at one end of a sliding plate to enter a clamping groove of the folding plate, the effect of limiting and fixing the folding plate and the cover plate is achieved, the cover plate can be rapidly disassembled, assembled and fixed by arranging a connecting assembly, and an angle detection module, a microswitch and the like in the shell can be conveniently maintained or replaced.

    本发明公开了一种角度检测型防过卷开关,属于吊具起重设备技术领域,包括壳体,所述壳体上端一侧设置有信号输出电缆,壳体内部一端设置有角度检测模块,壳体下端设置有密封垫,密封垫中设置有拉杆,本发明通过设置连接组件,盖板进行安装时通过竖杆带动若干横杆在固定框中移动,横杆移动带动滑板在固定框中移动,弹簧二受到压缩,之后再将盖板安装到壳体前端,同时盖板两端的折板通过插孔插入固定框中,松开竖杆,弹簧二弹伸推动滑板一端的若干卡块进入折板的卡槽中,达到对折板和盖板进行限位固定的效果,通过设置连接组件可快速对盖板进行拆装固定,方便对壳体中的角度检测模块和微动开关等进行维修或更换。
