Description

Rehabilitation equipment vehicle and speed regulating wheel thereof Technical Field The utility model relates to the technical field of medical rehabilitation equipment, in particular to a rehabilitation equipment vehicle and a speed regulating wheel thereof. Background Medical rehabilitation equipment vehicles are commonly used for assisting walking of old, weak or mobility-impaired people. When the medical rehabilitation device vehicle is used, the moving speed of the medical rehabilitation device vehicle is usually required to be adjusted according to the condition of a user, the normal speed is relatively low, in order to realize speed regulation, a speed reducing structure which is pressed against a tire is usually added on a vehicle frame, the speed is reduced by the friction force of the speed reducing structure on the tire, and therefore the speed regulation is carried out, but the tire is easy to damage, and the adjustment operation of the speed reducing structure is relatively troublesome. Disclosure of utility model The utility model aims to overcome the defects and shortcomings in the prior art and provides a rehabilitation equipment vehicle and a speed regulating wheel thereof. One embodiment of the present utility model provides a flywheel for a rehabilitation device vehicle, comprising: The hub is internally provided with a shaft hole, a first bearing and a second bearing which are sequentially arranged along the axial direction of the shaft hole are arranged in the shaft hole, and an outer ring of the first bearing and an outer ring of the second bearing are connected with the inner wall of the shaft hole; The frame connecting piece is used for being assembled with a frame of the rehabilitation equipment vehicle, is arranged on one side of the hub and is abutted against the inner ring of the first bearing; The speed regulation assembly comprises a fixing screw, an adjusting knob and an elastic compression piece, wherein the fixing screw is rotationally arranged on the frame connecting piece, the fixing screw penetrates through the shaft hole and sequentially penetrates through the inner ring of the first bearing and the inner ring of the second bearing, the adjusting knob is in threaded fit with the fixing screw, the hub is arranged on one side, far away from the frame connecting piece, of the hub, and the elastic compression piece is arranged between the adjusting knob and the hub.
