Description

Wheelchair with adjustable seat width

technical field

The utility model belongs to the technical field of medical equipment, in particular to a wheelchair with adjustable seat width.

Background technique

The wheelchairs launched on the market today all adopt the standard sitting width. However, the human body varies from fat to thin. If you sit in a wide wheelchair, tall people may feel crowded and lack comfort, while thin people may feel loose and insecure. If people of different body shapes are to be adapted, wheelchairs will be equipped with different sizes and specifications, which wastes materials and increases production costs.

Contents of the invention

The purpose of the utility model is to provide a wheelchair with an adjustable seat width and a simple structure and low cost.

The wheelchair with adjustable seat width provided by the utility model includes a wheelchair main body, chair wheels, a seat surface and a backrest; the wheelchair main body includes two left and right main body supports 1 and a transverse telescopic support 2 connecting the two main body supports 1; The length of the transverse telescopic support 2 is adjustable; thereby the width of the wheelchair can be adjusted.

In the utility model, the horizontal telescopic bracket 2 includes a main body longitudinal beam 3 and two lateral supports 4; the main body longitudinal beam 3 is arranged under the seat surface structure, which is consistent with the direction of the chair wheel, and the left and right sides of the main body longitudinal beam 3 are respectively provided with There is a pipe sleeve 5; one end of the two lateral supports 4 is respectively arranged in the left and right pipe sleeves 5, and the other end is respectively connected with the two chair main body brackets 1; the lateral support 4 can slide and expand in the sleeve pipes . As shown in Figure 1.

In the utility model, the lateral support 4 is provided with several openings, and the corresponding position of the pipe sleeve 5 is provided with a limit hole; another pin is provided, which can pass through the limit hole and the opening at the same time, and fix the The relative position of lateral support 4 and sleeve 5. as shown in picture 2.

In the utility model, when it is necessary to adjust the sitting width of the wheelchair, the horizontal telescopic bracket 2 is adjusted to a suitable length, and the latch is inserted into the limit hole to fix the relative position of the lateral support 4 and the pipe sleeve 5; thereby adjusting two The distance between the main body supports 1 is the width of the seat surface.

In the utility model, the seat surface and the backrest of the wheelchair adopt elastic cloth art, and the stretching function of the cloth is used to adapt to different wheelchair widths; The strap-type structure can be retracted in length to adapt to different wheelchair widths.

The utility model has the advantages of fewer spare parts, low maintenance cost and simple process; the distance between the control part and the steering part of the steering mechanism can be changed freely, and provides each user with a ride comfort more suitable for himself.

Detailed ways

The wheelchair with adjustable seat width provided by the utility model includes a wheelchair main body, chair wheels and a seat surface; the wheelchair main body includes two left and right main body supports 1 and a transverse telescopic support 2 connecting the two main body supports 1; two main body supports 1 are all welded by aluminum alloy tubes; the horizontal telescopic support 2 is also made of aluminum alloy, and its length is adjustable;

The horizontal telescopic bracket 2 includes a main body longitudinal beam 3 and two lateral supports 4; the main body longitudinal beam 3 is arranged under the seat surface structure, and is consistent with the direction of the chair wheel, and the left and right sides of the main body longitudinal beam 3 are respectively welded with a circular tube shape the pipe sleeve 5; the two horizontal supports 4 are aluminum alloy round tubes, and its outer diameter matches the inner diameter of the pipe sleeve 5; The main body bracket 1 of the chair is welded and connected; the lateral support 4 can slide and expand in the sleeve pipe 5. As shown in Figure 1.

The lateral support 4 is provided with 4 openings, and the distance between each opening is 1 cm. A position limiting hole is provided at a corresponding position on the pipe sleeve 5; Holes are used to fix the relative positions of the transverse support 4 and the pipe sleeve 5. as shown in picture 2.

In the utility model, when it is necessary to adjust the sitting width of the wheelchair, the horizontal telescopic bracket 2 is adjusted to a suitable length, and the latch is inserted into the limit hole to fix the relative position of the lateral support 4 and the pipe sleeve 5; thereby adjusting two The distance between the main body supports 1 is the width of the seat surface.

The seat surface of the wheelchair and the edge of the backrest are connected with the main body bracket 1 of the wheelchair by a strap type connection, and the strap type structure can be retracted in length to adapt to different wheelchair widths.

The utility model has the advantages of fewer spare parts, low maintenance cost and simple process; the distance between the control part and the steering part of the steering mechanism can be changed freely, and provides each user with a ride comfort more suitable for himself.
