a wheelchair

Abstract

The invention discloses a wheelchair, which comprises a main body frame, a chair back arranged on the main frame, a lifting mechanism and a belt conveying mechanism, the chair back includes a mounting seat fixed to the main body frame, and the mounting seat is symmetrically arranged on Both sides of the main body frame also include a chair back rod, which is rotationally connected with the mounting seat through a rotating shaft provided at its lower end, a driven gear is fixedly arranged on the rotating shaft, and a driven gear is fixedly arranged on the rotating shaft. A self-locking motor is fixed on the frame, and a driving gear is fixedly arranged on the output shaft of the self-locking motor. Shaped backrest belt; there is also a scraper mechanism on the path of the conveying mechanism. The lifting mechanism of the present invention has a stronger lifting force, and has a very strong self-locking function, which prevents the defect of falling; the back of the chair can be tilted slowly before the conveyor belt is started, and assists the patient to lie on the conveyor belt; and by setting The scraper mechanism effectively removes the dirt on the surface of the conveyor belt.

Description

technical field [0001] The invention relates to a wheelchair, in particular to a wheelchair which can conveniently transport a patient from the wheelchair to the bed. Background technique [0002] At present, the wheelchair is an important tool for rehabilitation, and it is also a means of transportation for many people with leg injuries or disabilities. However, when the existing wheelchair is in use, it is difficult for the user to move from the wheelchair to the bed, and the help of an outsider is often needed to achieve the above purpose. [0003] Based on the above problems, the applicant has developed a seat with handling in the early stage, see Figure 1 to Figure 2 , which includes a main frame 1, on which a chair back 2 is arranged, the chair back 2 includes a back board 20 matched with the main frame, one end of the back board 20 is rotated, and the other end is buckled on the main frame 1 . [0004] The main frame 1 is provided with a roller connecting plate 3, ...

AI Technical Summary

Problems solved by technology

[0005] The above structure has the following defects: 1) The lifting force of the lifting mechanism is not strong, and the torque requirement for the motor is relatively high. In addition, the self-locking ability of the lifting mechanism is poor, and it is easy to happen when the roller connecting plate is not buckled on the bed. board drop problem;

[0006] 2) There is no effective means of lifting the patient's back. Before the conveyor belt is started, the patient can only lie on the conveyor belt slowly by himself;
