Problems solved by technology

The biggest technical difficulty in tailoring is how to accurately measure the user's body size. At present, most of the domestically trained personnel use a tape measure to measure the size of the user according to experience. There are various sizes of measurement. There is no way to help users measure the exact size in a short time
Due to the differences in the professional level of each surveyor, some users are not very satisfied with the customized wheelchair
[0005] The current utility model patent application number is 200920173293.8, which discloses a magnesium alloy portable wheelchair, including: rear handbrake device, back folder, armrest lifting adjustment device, guide wheel device, standing brake, anti-tilt device, big wheel assembly , X-shaped folding bracket, etc.; the main frame of the wheelchair and the frame material of the X-shaped folding bracket are magnesium alloys; Through the bearing support and transmission; through the different installation of two sets of positioning holes on the X-shaped folding bracket, the seat surface of the wheelchair can have two widths; the wheelchair is equipped with a standing brake device; the beneficial effect of the utility model is that the wheelchair is especially suitable It is used by men whose height is between 1.65m and 1.75m; and the wheelchair has a simple structure, adjustable wheelchair width, adjustable wheelchair seat height, adjustable seat inclination angle, adjustable wheelchair footrest height, body frame adopts Magnesium alloy material, the total weight of the car body is light, and the wheelchair tires are non-inflatable tires. This patent is through the different installation of two sets of positioning holes on the X-shaped folding bracket, so that the seat surface of the wheelchair can have two widths, but this structure adjustment seat width is not up to dimensional accuracy

Abstract

The invention discloses a width adjusting device which can connect a first connector and a second connector and adjust the width between the first connector and the second connector. The width adjusting device comprises a first tube, a second tube, a positioning tube, a movable rod and a limit part, wherein the first tube is connected with the first connector, the second tube is connected with the second connector, the first tube can axially move in the second tube, the positioning tube is located in the second tube, the movable rod is located in the positioning tube and can axially move in the same, and the limit part is located on the first tube and the second tube and limits the working travel between the first tube and the second tube. An adjustable wheelchair with the width adjusting device comprises a body. The first connector is the right frame of the wheelchair. The second connector is the left frame of the wheelchair. By the width adjusting device, stepless adjusting can be achieved, and the left frame and the right frame can be adjusted to optional required angles.

Description

technical field [0001] The invention relates to a width adjusting device and its application, in particular to a width adjusting device and an adjustable wheelchair with the width adjusting device. Background technique [0002] The width adjusting device can adjust the width between the first connecting part and the second connecting part, so that the width between the first connecting part and the second connecting part can be adjusted according to different needs. It is more troublesome and there are adjustment levels, which makes the adjusted size accuracy not high. [0003] The wheelchair is an important tool for rehabilitation. It is not only a means of transportation for the physically disabled, but more importantly, it enables them to use the wheelchair to perform physical exercises and participate in social activities. The most important consideration when choosing a wheelchair is the size of the wheelchair, especially the size of the wheelchair. Whether the seat wi...
