Abstract

The present invention relates to a wheelchair pedal driven to lift by a rack. A pedal tube is fixedly mounted on a frame of a wheelchair; a pedal is mounted on the lower end of the pedal tube; a telescopic tube is coaxially sleeved by the pedal tube; a rack is arranged on the upper part of the telescopic tube in the pedal tube; the pedal is fixedly mounted on the lower end of the telescopic tube; a mounting seat is fixedly arranged on the part, corresponding to the part with the rack of the telescopic tube, of the pedal tube; a straight gear is horizontally mounted in the mounting seat; and the straight gear is meshed with the rack arranged on the telescopic tube in the pedal tube, so that the telescopic tube lifts when the rack is meshed with the straight gear, and the pedal is driven to lift in the pedal tube. The entire structural design is scientific; the idea is ingenious; the technical problem of the existing pedal is overcome; and the market prospect is very broad.

Description

technical field [0001] The invention belongs to the field of wheelchairs, and relates to the improvement of wheelchair pedals, in particular to a wheelchair pedal for lifting and lowering driven by a rack. Background technique [0002] Wheelchairs are commonly used medical rehabilitation equipment provided to participating patients or elderly people, and are also special tools for walking. Most of these wheelchairs are equipped with pedals, which are convenient for the above-mentioned people to use. Most of the current pedals are installed at the bottom of the pedal tube, and the pedal itself can rotate inwards to reduce the obstacles to people's feet and legs. [0003] Through searching, it is found that there are many published patent documents related to the application of the present invention, and the following three are close: [0004] 1. A novel wheelchair pedal (CN202682221U), comprising a pedal, a leg support tube, and a spring positioning device. The pedal is inst...
