Abstract
The utility model relates to a cross-shaped crutch wheel, in particular to the technical field of vehicles. The cross-shaped crutch wheel is designed for a wheelchair and a minitype ride instead of walk vehicle to climb over obstacles such as steps, etc., and comprises a wheel boss 1, an auxiliary crutch 2, a fixed wheel 3 and a rubber plus material 4, wherein, the wheel boss 1 is positioned at the center part, and the auxiliary crutch 2 is arranged in a cross shape on the wheel boss 1. The outer end of the auxiliary crutch 2 is provided with a fixed wheel 3, and the fixed wheel adopts a languishment structure corresponding to the auxiliary crutch and contacts a staircase table-board in a rolling mode. The outer surface of the crutch 2 and the fixed wheel are spread with the rubber plus material 4, so that the friction can be increased to prevent the slippage, and the working face of the steps can be prevented from damage. When the user goes upstairs and downstairs, the fixed wheel 3 abuts and hooks the staircase, so as to cause the wheelchair or the ride instead of walk vehicle to run smoothly at the staircase.
