Description

A wheelchair with a portable table

technical field

The invention relates to a wheelchair, in particular to a wheelchair with a portable table.

Background technique

The wheelchair is an important rehabilitation tool. It is not only a means of transportation for the physically disabled, but also enables them to perform physical exercises and participate in social activities with the help of wheelchairs. At the same time, wheelchairs are often needed during the examination of patients. However, During the examination, patients often carry a lot of items, and these items often have no place to store them.

The existing wheelchair is fixed with a dining table, but it is fixed on the wheelchair by bolts, so it is inconvenient to disassemble. The trouble of disassembling not only increases the workload of the medical staff, but also prolongs the waiting time of the patient, and the inspection efficiency is low.

Contents of the invention

The purpose of the present invention is to provide a wheelchair with a portable table to solve the problem of inconvenient storage of articles carried by patients during the examination process, and to store articles on the portable table safely and conveniently.

The present invention is for solving the deficiencies of the above-mentioned technical problems, and the technical scheme adopted is:

A wheelchair with a portable table, comprising a wheelchair body, the front end of the wheelchair body is provided with a portable table for storing user items, and the portable table is fixed on the On the wheelchair body, the horizontal bar of the L-shaped support is rotated at the bottom of the portable table so that the L-shaped support can be folded and stored at the bottom of the portable table. The connector on the body bracket, the connector includes a U-shaped slot welded on the bottom of the vertical bar of the L-shaped support and cooperates with the U-shaped slot to realize the adjustment of clamping and fixing the vertical bar on the wheelchair body bracket bolt.

The wheelchair body is also provided with a speed limiting device, which includes a centrifugal pulley, a spring, a centrifugal pin, and a large pulley, a small pulley and a driving pulley linked by a belt, wherein the large pulley and the small pulley are installed on the wheelchair body On the bracket, the driving wheel and the rear wheel of the wheelchair body are arranged on the same rotation axis, the centrifugal wheel and the small pulley are arranged on the same rotation axis, and the centrifugal pin is arranged in the radially distributed channel on the centrifugal wheel, and is directed to the centrifugal wheel with the force. The spring connection of the rotating shaft center, the rotation of the rear wheel of the wheelchair body sequentially drives the centrifugal wheel to rotate through the driving wheel, the large pulley and the small pulley, so that the centrifugal pin contacts the ground under the action of centrifugal force to generate friction to limit the speed.

The table top of the portable table is provided with a baffle to prevent items from slipping and a support rod for hanging the pressure extension tube.

The bottom of the portable table is provided with a restriction belt that can fix the L-shaped support on the bottom of the portable table.

A hook for hanging the drainage bag is also provided on the side wall of the wheelchair body.

The restriction band is any one of adhesive bands or ropes fixed at the bottom of the portable table.

The beneficial effects of the present invention are: the present invention has a simple structure and reasonable design, is convenient for patients to store items, reduces the workload of medical staff, and is provided with a support rod to avoid the danger caused by the pressure extension tube being entangled in the wheel of the wheelchair.

Detailed ways

As shown in the figure, the specific implementation method is as follows:

A wheelchair with a portable table, comprising a wheelchair body 7, the front end of the wheelchair body 7 is provided with a portable table 6 for storing user items, and the portable table 6 is formed into an L shape by connecting a horizontal bar and a vertical bar. The support member 3 is fixed on the wheelchair body 7, and the cross bar of the L-shaped support member 3 is rotated and arranged at the bottom of the portable table 6 so that the L-shaped support member 3 is folded and stored at the bottom of the portable table 6. On the vertical bar of the L-shaped support member 3 A connector 2 for installing the L-shaped support 3 on the bracket of the wheelchair body 7 is welded, and the connector 2 includes a U-shaped slot 201 whose bottom is welded on the vertical bar of the L-shaped support 3 and a U-shaped The clamping groove 201 cooperates to realize the adjustment bolt 202 that clamps and fixes the vertical bar on the bracket of the wheelchair body 7 .

The wheelchair body 7 is also provided with a speed limiting device, which includes a centrifugal pulley 14, a spring 11, a centrifugal pin 12, and a large pulley 9, a small pulley 13 and a driving pulley 10 linked by a belt, wherein the large pulley 9 and the small pulley 13 are installed on the support of the wheelchair body 7, the driving wheel 10 and the rear wheel of the wheelchair body 7 are arranged on the same rotation axis, the centrifugal wheel 14 and the small pulley 13 are arranged on the same rotation axis, and the centrifugal pin 12 is arranged on the centrifugal wheel 14 In the radially distributed through groove, and connected with the spring 11 whose force points to the rotation axis of the centrifugal wheel 14, the rotation of the rear wheel of the wheelchair body 7 drives the centrifugal wheel 14 to rotate through the driving wheel 10, the large pulley 9 and the small pulley 13 in sequence Thereby the centrifugal pin 12 is contacted with the ground under the action of centrifugal force to generate friction to play a speed-limiting effect.

The desktop of the portable table 6 is provided with a baffle plate 4 to prevent items from slipping and a support rod 5 for hanging a pressure extension tube.
