Novel wheelchair braking and parking control device

Abstract

The invention discloses a novel wheelchair braking and parking control device, and particularly relates to the technical field of wheelchairs. The novel wheelchair braking and parking control device comprises a wheelchair support and a tire, wherein the tire is arranged on one side of the wheelchair support; a supporting plate is fixedly arranged on the rear side of the front end of the wheelchair support; a shell is arranged on one side, which is close to the tire, of the supporting plate; a parking control shifting sheet and a braking and parking shifting sheet are arranged in the shell; and the parking control shifting sheet is located on the top of the braking and parking shifting sheet. Through rotation of the parking control shifting piece, a positioning tooth and a positioning groove on the braking and parking shifting piece are clamped and fixed, the braking and parking shifting piece is extruded while the positioning tooth and the positioning groove are clamped and fixed, so that the lower end of the braking and parking shifting piece moves to the direction of the tire and is contact with the tire, and the tire achieves a parking effect. Since the positioning tooth and the positioning groove are matched according to the principle of engineering mechanics, after the positioning tooth and the positioning groove are clamped, no matter when the tire moves forwards or backwards, the braking and parking shifting piece can not move along with the tire.

Description

technical field [0001] The invention relates to the technical field of wheelchairs, in particular to a novel braking and parking control device for wheelchairs. Background technique [0002] The wheelchair is an important tool for the rehabilitation of patients. Its function is set to serve specific groups of people or the elderly, especially for people with limited mobility. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to Able to use a wheelchair for physical exercise and social activities. Ordinary wheelchairs are generally composed of four parts: wheelchair frame, wheels, brake device and seat. On the basis of ordinary wheelchairs, hand-operated wheelchairs are equipped with hand-operated devices. [0003] The existing common wheelchair brake and parking control devices are composed of multiple components and are controlled separately. The production process is complex, the operation is laborious and inflexi...

AI Technical Summary

Problems solved by technology

[0003] The existing common wheelchair brake and parking control devices are composed of multiple components and are controlled separately. The production process is complex, the operation is laborious and inflexible, and the brake and parking control devices are prone to failure on uneven road conditions and slope sections. Hidden dangers; and equipment composed of multiple components, after a long period of use, it is very easy to cause friction and damage between the components, resulting in control failure and short service life
