Abstract

The invention discloses a labor-saving hand push wheel which comprises a hug and an outer ring. The hub is connected with the outer ring by a plurality of connecting rods, the connecting rods are radially uniformly distributed, a plurality of elliptical protrusions are arranged on the surface of the outer ring and are uniformly distributed on the surface of the outer ring, and a protective cover is arranged on a side surface of the outer ring and is in the shape of a hollow circular truncated cone. Compared with the traditional hand push wheel, the labor-saving hand push wheel has the advantages that the labor-saving hand push wheel is simple in structure and convenient to operate, and labor can be saved when the labor-saving hand push wheel is operated.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to a labor-saving push wheel for installation on wheelchairs. Background technique [0002] Wheelchairs are an important tool for rehabilitation. Wheelchairs are not only a means of transportation for physically disabled and handicapped people, but more importantly, they use wheelchairs to perform physical exercises and participate in social activities. Hand push wheel is to be installed on the wheelchair and is used to promote the running wheel that wheelchair advances, but the hand push wheel on the existing wheelchair is inconvenient to push and operate, more laborious. Contents of the invention [0003] In order to overcome the above disadvantages, the present invention provides a labor-saving hand wheel, including a hub and an outer ring, the hub and the outer ring are connected by a number of connecting rods, the connecting rods are evenly distributed in the radial direc...
