The invention relates to a front-rear four-claw equal-force wheelchair tightening and fixing device which comprises two symmetrically-arranged wheelchair fixing steel wire ropes, hooks used for fixing a wheelchair are arranged at the two ends of each wheelchair fixing steel wire rope respectively, and the middle of each wheelchair fixing steel wire rope is connected with a steel wire rope guide mechanism. The steel wire rope guide mechanism is matched with a wheelchair fixing steel wire rope to form a pulley assembly, the pulley assembly is connected with a four-bar mechanism, the four-bar mechanism is matched with a double-end left-right-handed screw rod, the two ends of the double-end left-right-handed screw rod are provided with threaded sections opposite in rotation direction, and each threaded section is provided with a movable nut. And the nut is hinged with one end of the four-bar mechanism. The wheelchair is convenient to operate, and the fixing forces of the four fixing points of the wheelchair are the same, so that in the running process of a vehicle, a wheelchair passenger does not feel uncomfortable due to different fixing forces of the four fixing points of the wheelchair.

    本发明涉及一种前后四爪等力轮椅收紧固定装置,包括两根对称布置的轮椅固定钢丝绳,每根轮椅固定钢丝绳的两端分别设有用于固定轮椅的挂钩,每根轮椅固定钢丝绳的中部连接钢丝绳导向机构,所述钢丝绳导向机构与轮椅固定钢丝绳相配合组成滑轮组件,所述滑轮组件与四连杆机构连接,所述四连杆机构与双头左右旋丝杆配合设置,所述双头左右旋丝杆的两端具有旋转方向相反的螺纹段,每个螺纹段上布置有可移动的螺母,所述螺母与四连杆机构的一端铰接。本发明操作方便,轮椅四个固定点的固定力相同,因此在车辆行驶过程中,轮椅乘坐人员不会因由于轮椅四点固定力不同而产生不适的感受。
