Abstract

The invention provides a wheelchair falling strength testing device comprising a testing platform, a support frame, a driving motor, a cam mechanism, a guide column mechanism, a transmission plate, a nylon belt used for fastening a wheelchair and an infrared counter. The structure of the whole device is simple. The wheelchair is placed on the testing platform and is connected with the nylon belt, the motor is started, and the detection function of the whole device is automatically realized according to the mechanical transmission principle. Through the mechanical movements of the cam mechanism and the guide column mechanism, the automatic up and down movements of the wheelchair are realized, moving the wheelchair by an operator is not needed, thus the manpower is saved, the artificial interference of a test is avoided, and the operation is simple and convenient. In addition, the testing device can automatically count, and the disadvantages of easy wrong and time and labor consuming of manual counting are overcome.

Description

technical field [0001] The invention relates to a test device, in particular to a wheelchair drop strength test device. Background technique [0002] There are nearly 200 million elderly people in my country, and about 6.5 million of them suffer from Alzheimer's disease. In addition, there are more than 40 million diabetic patients in my country, and nearly 4 million of them are complicated with lower limb necrosis. In addition, there are about 500,000 new people with lower limb disabilities caused by car accidents, industrial injuries, and other accidents every year. In the next 50 years, the proportion of the population over the age of 60 is expected to double. At the same time, the number of disabled people caused by various disasters and diseases is also increasing year by year. They have different degrees of loss of ability, such as walking, vision, hands and language, etc. . This is a huge and special group, the weak in society, and needs the care of the whole socie...
