The wheel rotates so that the centrifugal pin contacts the ground under the action of centrifugal force to generate friction to limit the speed. The warm protection belt provided by the present invention not only plays the role of keeping out the cold, but also prevents the patient from slipping out of the wheelchair, and a speed-limiting mechanism is provided to effectively control the speed of the wheelchair and avoid danger.

Description

A wheelchair with a protective belt

technical field

The invention relates to a wheelchair, in particular to a wheelchair with a warm protection belt.

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. For users, wheelchairs are too fast, which is not only prone to danger, And it is not conducive to the recovery of patients.

Contents of the invention

The purpose of the present invention is to provide a wheelchair with a warm protection belt to solve the problem that the wheelchair is too fast to cause danger and is easily affected by cold wind when used outdoors. , At the same time, the patient is prevented from slipping out of the wheelchair, and a speed-limiting mechanism is set to effectively control the speed of the wheelchair and avoid danger.

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

A wheelchair with a warming belt, including a wheelchair body, the front end of the wheelchair body is provided with a warming belt, and the two ends of the warming belt are provided with connecting ropes for fixing the warming belt on the wheelchair body. The wheelchair body A speed-limiting device is also arranged on it, 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 bracket of the wheelchair body, and the driving pulley and The rear wheel of the wheelchair body is set with the rotating shaft, the centrifugal wheel and the small pulley are set with the rotating shaft, the centrifugal pin is set in the radially distributed through groove on the centrifugal wheel, and is connected with the spring whose force points to the rotating axis of the centrifugal 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.

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

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 beneficial effects of the present invention are: the warm protective belt provided by the present invention not only plays the role of keeping out the cold, but also prevents the patient from slipping out of the wheelchair, and a speed-limiting mechanism is provided to effectively control the speed of the wheelchair and avoid danger.

detailed description

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

A wheelchair with a warming belt, comprising a wheelchair body 4, the front end of the wheelchair body 4 is provided with a warming belt 2, and the two ends of the warming belt 2 are provided with connecting ropes for fixing the warming belt 2 on the wheelchair body 4 3. The wheelchair body 4 is also provided with a speed limiting device, which includes a centrifugal pulley 10, a spring 7, a centrifugal pin 8, and a large pulley 5, a small pulley 9 and a driving pulley 6 linked by a belt, wherein the large pulley 5 and the small pulley 9 are installed on the support of the wheelchair body 4, the driving wheel 6 and the rear wheel of the wheelchair body 4 are arranged on the same rotation axis, the centrifugal wheel 10 and the small pulley 9 are arranged on the same rotation axis, and the centrifugal pin 8 is arranged on the centrifugal wheel 10 In the radially distributed through groove, and connected with the spring 7 whose force points to the rotation axis of the centrifugal wheel 10, the rotation of the rear wheel of the wheelchair body 4 drives the centrifugal wheel 10 to rotate through the driving wheel 6, the large pulley 5 and the small pulley 9 in sequence Thereby the centrifugal pin 8 is contacted with the ground under the action of centrifugal force to generate friction and play the speed limiting effect.

A hook 1 for hanging a drainage bag is installed on the side wall of the wheelchair body 4 .

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 4 .

When the present invention is in use, if the user sits on the top and it is cold outside, the warm protection belt can be mounted on and fixed on the wheelchair through the connecting rope; The speed limiting mechanism provided, when the wheelchair speed is too fast, can make the centrifugal pin overcome the active force of the spring and stretch out the centrifugal wheel, and contact with the ground to generate friction, thereby slowing down the wheelchair speed.

The technical solutions and implementation methods listed in the present invention are not limiting, and solutions that are equivalent to or have the same effect as the technical solutions and implementation methods listed in the present invention are within the protection scope of the present invention.
