Abstract

The invention discloses a wheelchair roll wheel assembly with a shock absorption structure. The roll wheel assembly comprises a front roll wheel component and a rear roll wheel component, wherein the front roll wheel component comprises a front rotating shaft, while the rear roll wheel component comprises a rear rotating shaft; the roll wheel assembly also comprises a supporting cross beam and two first elastic pieces, wherein four sliding holes are formed in the lower part of the supporting cross beam, one ends of the first elastic pieces are rotatably connected with the front rotating shaft, and the first elastics are slidingly connected with the sliding holes. The wheelchair roll wheel assembly with the shock absorption structure has the advantage that four shock absorbing elastic pieces are provided to achieve good shock absorption effect and high load capability.

Description

technical field [0001] The invention relates to a roller assembly, more precisely a wheelchair roller assembly with a shock-absorbing structure. Background technique [0002] The roller assembly of the wheelchair in the prior art relies on the spring to vibrate the wheelchair, but the damping effect of the spring is poor and the load is small, so it is not suitable for obese people. Contents of the invention [0003] The present invention mainly solves the technical problems existing in the prior art, thereby providing a wheel chair roller assembly with a shock-absorbing structure with four shock-absorbing shrapnels, good shock-absorbing effect and large load. [0004] Above-mentioned technical problem of the present invention is mainly solved by following technical scheme: [0005] A wheelchair roller assembly with a shock-absorbing structure, the roller assembly includes a front roller part and a rear roller part, the front roller part includes a front rotating shaft, a...
