Abstract

The invention discloses a three-gear speed-variable manual push wheelchair. The three-gear speed-variable manual push wheelchair comprises two wheelchair racks (103) which are connected together through a crossing support (102), and a backrest (104), a seat cushion (105) and a baffle (106) are arranged between the wheelchair racks (103); each wheelchair rack (103) is provided with a front wheel (107) and a rear wheel (108), and a manual push ring (109) is arranged at the inner side of each rear wheel (108), and is connected with the corresponding rear wheel (108) through a three-gear gearbox (101); each three-gear gearbox (101) is connected with a transmission (111) fixed to the corresponding wheelchair rack (103) through a shift wire (110). By means of the three-gear speed-variable manualpush wheelchair, three-gear speed adjusting can be achieved, thus the maneuverability and the automation of use of the wheelchair can be improved, and meanwhile, speed-variable adjustment is stable and convenient and does not easily break down.

Description

technical field [0001] The invention relates to a three-speed variable-speed manual wheelchair, which belongs to the technical field of variable-speed manual wheelchairs. Background technique [0002] Wheelchairs are a basic means of transportation in the elderly and disabled service system.
