technical field

The invention relates to a wheelchair, in particular to a multifunctional wheelchair.

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 solve the problem of inconvenient storage of items carried by patients during the examination process, and provide a multifunctional wheelchair, which can store items on a 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:

The wheelchair body is also provided with a speed limiting device, and the speed limiting device 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 On the bracket of the body, 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 aligned with the force pointing to the centrifugal The spring connection of the rotation axis of the wheel, 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 centrifugal wheel is located above the line connecting the lowest end of the front wheel and the rear wheel of the wheelchair body.

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

The bottom of the portable table is provided with a restriction belt that can fix the support rod 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.

Both the slot block I and the slot block II are connecting blocks provided with a through slot matching with 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 is simple in structure and reasonable in design, convenient for patients to store items, and reduces the workload of medical staff. At the same time, a suspension rod is provided 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 multifunctional wheelchair, comprising a wheelchair body 7, the front end of the wheelchair body 7 is provided with a portable table 8 that is convenient for storing user items, and the portable table 8 is installed on the wheelchair body 7 through a connecting piece at the bottom thereof. The connectors include a draw-in block 16 that cooperates with the handles on both sides of the wheelchair body 7 and a support rod 3 that cooperates with the brackets of the wheelchair body 7 legs. One end of the support rod 3 is hinged at the bottom of the portable table 8, and the other end passes through the draw-in block. II2 realizes that the support rod 3 is clamped on the bracket of the wheelchair body 7 legs.

The wheelchair body 7 is also provided with a speed limiting device, and the speed limiting device includes a centrifugal wheel 10, a spring 13, a centrifugal pin 12 and a large pulley 15, a small pulley 11 and a driving pulley 14 linked by a belt, wherein the large Belt pulley 15 and small belt pulley 11 are installed on the support of wheelchair body 7, driving wheel 14 and the rear wheel of wheelchair body 7 are arranged on the same rotation axis, centrifugal wheel 10 and small belt pulley 11 are arranged on the same rotation axis, and centrifugal pin 12 is arranged on centrifugal wheel 10 In the through groove distributed radially on the top, it is connected with the spring 13 whose force points to the rotation axis of the centrifugal wheel 10. The rotation of the rear wheel of the wheelchair body 7 drives the centrifugal wheel 10 through the driving wheel 14, the large pulley 15 and the small pulley 11 in sequence. Rotate so that the centrifugal pin 12 contacts with the ground under the action of centrifugal force to generate friction and play a speed-limiting effect.

The centrifugal wheel 10 is located above the line connecting the lowest ends of the front wheel and the rear wheel of the wheelchair body 7 .

The desktop of the portable table 8 is provided with a baffle plate 5 to prevent items from slipping and a suspension rod 4 for suspending the pressure extension pipe.

The bottom of the portable table 8 is provided with a restriction band 9 that can fix the support rod 3 on the bottom of the portable table 8 .
