Technical Field

[0001] This utility model belongs to the field of wheelchair technology, and specifically relates to a leg exercise device for wheelchairs. Background Technology

[0002] Existing wheelchairs consist of a main frame, on which footrests are typically installed for leg support. These footrests are usually fixed to the main frame or are adjustable in angle, making it impossible to train the legs and thus limiting the functionality of the wheelchair. Utility Model Content

[0003] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a leg exercise device for wheelchairs to solve the problems mentioned in the background art.

[0004] The above-mentioned technical objective of this utility model is achieved through the following technical solution:

[0005] A leg exercise device for a wheelchair includes a wheelchair frame, which includes two main side frames connected by an X-shaped folding frame. A pedal connecting rod is hinged to each of the two main side frames, and pedals are hinged to the ends of the two pedal connecting rods. A T-shaped frame is detachably connected to the top of each of the two main side frames. A spring is detachably connected to one end of each of the two pedals, and the other end of the spring is detachably connected to the T-shaped frame. A heating plate is provided on the top surface of each pedal, and a heat-insulating foot cover is detachably connected to each pedal.

[0006] When you step onto the pedal and push forward, the pedal will flip. The spring mechanism then provides a restoring force. Repeating this motion effectively exercises your legs. Simultaneously, a heating plate on the pedal, along with insulated foot covers, keeps your feet warm and promotes blood circulation. The insulated foot covers are located above the heating plate.

[0007] Preferably, the foot pedal includes a pedal body, and a hinge seat is provided at one end of the pedal body, which is hinged to the pedal connecting rod.

[0008] Preferably, a heating plate mounting cavity is formed on the upper surface of the pedal body, and the heating plate is placed in the heating plate mounting cavity.

[0009] Preferably, the heating plate is an electric heating plate, and the inner wall of the heating plate mounting cavity is provided with a wire through hole. The heating plate wire passes through the wire through hole and passes through the heating plate mounting cavity. A control box is provided on the wheelchair frame, and the heating plate wire passes through the pedal connecting rod and the main side frame and then connects to the control box.

[0010] The pedal connecting rod and the main side frame are both made of hollow steel pipes.

[0011] Preferably, the two main side frames have insertion holes on their mating surfaces. The two ends of the crossbar of the T-shaped frame are inserted into the insertion holes, and the two sides of the vertical bar of the T-shaped frame have several first hooks arranged vertically at intervals. The first end of the spring is hooked onto any one of the first hooks. The inner end of the foot pedal has a second hook, and the second end of the spring is hooked onto the second hook. By hooking the first end of the spring onto different first hooks, the tension of the spring can be adjusted as needed.

[0012] Preferably, the insulated foot cover includes a cover body, at least one elastic sleeve is provided on the bottom surface of the cover body, and several blocking blocks are provided on the bottom surface of the foot pedal; the elastic sleeve is snapped onto the blocking blocks.

[0013] Preferably, the bottom surface of the heat-insulating foot cover is provided with an aluminum foil layer to improve thermal conductivity.

[0014] In this application, the temperature of the heating plate is set to 35-40 degrees Celsius. This is prior art and will not be described further here.

[0015] In summary, the present invention has the following main advantages:

[0016] The pedal in this application is connected to a T-shaped frame via a spring. When the foot steps on the pedal and pushes forward, the pedal flips. The spring then provides a restoring force, and repeated movement achieves the purpose of leg exercise. Simultaneously, a heating plate is installed on the pedal, along with insulated foot covers, to keep the feet warm and promote blood circulation. The insulated foot covers are located above the heating plate. Attached Figure Description

[0023] Example

[0024] refer to Figures 1 to 6This embodiment of a wheelchair leg exercise device includes a wheelchair frame 1, which includes two main side frames 2 connected by an X-shaped folding frame. A pedal connecting rod 3 is hinged to each of the two main side frames, and pedals 4 are hinged to the ends of the two pedal connecting rods. A T-shaped frame 5 is detachably connected to the top of each of the two main side frames. A spring 6 is detachably connected to one end of each pedal, and the other end of the spring 6 is detachably connected to the T-shaped frame. A heating plate 7 is provided on the top surface of each pedal, and an insulated foot cover 8 is detachably connected to each pedal.

[0025] When you step onto the pedal and push forward, the pedal will flip. The spring mechanism then provides a restoring force. Repeating this motion effectively exercises your legs. Simultaneously, a heating plate on the pedal, along with insulated foot covers, keeps your feet warm and promotes blood circulation. The insulated foot covers are located above the heating plate.

[0026] The footrest includes a footrest body 9, with a hinge seat 10 at one end, which is hinged to a footrest connecting rod. A heating plate mounting cavity 11 is formed on the upper surface of the footrest body, and a heating plate (electric heating plate) is placed within the cavity. A wire through-hole 12 is provided on the inner wall of the cavity, through which the heating plate wire passes.
