Description

Technical Field

[0001] The utility model belongs to the technical field of rehabilitation training and relates to an auxiliary weight-reducing device for lower limb rehabilitation training. Background Art

[0002] Stroke is a cerebrovascular disease with extremely high morbidity, mortality and disability rates. It is often accompanied by functional disorders such as balance, cognition, speech, and movement. The most prominent of these is lower limb motor dysfunction. Therefore, stroke patients need to use rehabilitation equipment to assist in relevant lower limb rehabilitation training.

[0003] At present, common limb rehabilitation equipment on the market includes equipment for upper limb rehabilitation and lower limb rehabilitation equipment designed for lower limbs. Most of them use weight-reducing belts to support the user's waist and abdomen to prevent the user from falling during training; however, the weight of the upper body usually exceeds that of the lower body, which makes it difficult for patients to control their center of gravity during rehabilitation training. At the same time, in the early stages of rehabilitation, the lower limbs cannot bear the full weight of the body, resulting in poor rehabilitation training effects. Therefore, we propose an auxiliary weight-reduction device for lower limb rehabilitation training. Utility Model Content

[0004] The purpose of this utility model is to address the above-mentioned problems in the existing technology and propose an auxiliary weight-reducing device for lower limb rehabilitation training. The technical problem to be solved by this device is: how to make the lower limb rehabilitation training device easier for patients to control the gravity borne by their lower limbs and improve the effect of rehabilitation training.

[0005] The purpose of this utility model can be achieved through the following technical solutions:

[0006] An auxiliary weight-reduction device for lower limb rehabilitation training comprises a U-shaped plate and a weight-reduction component, wherein the weight-reduction component comprises a mounting plate, which is fixed to the U-shaped plate, an electric push rod and two limit sleeves fixed above the mounting plate, the electric push rod is located between the two limit sleeves, a lifting block is fixed above the electric push rod and the two limit sleeves, a sliding groove is provided on the lifting block, a bidirectional threaded rod is provided for rotation inside the sliding groove, the end of the bidirectional threaded rod passes through the lifting block, a handwheel is fixed to the end of the bidirectional threaded rod, two fixed columns are threadedly connected to the bidirectional threaded rod, the two fixed columns are both slidably arranged inside the sliding groove, the ends of the two fixed columns are fixed with an armpit support plate, a walking component is provided on the side of the U-shaped plate, and two support components are provided on the walking component.

[0007] The two underarm support plates are symmetrical to each other, and the underarm support plates are U-shaped, with rounded corners formed on the tops of the underarm support plates.

[0008] With the above structure, the U-shaped underarm support plate can limit the position of the rehabilitation person, and at the same time can support the underarms of the rehabilitation person to reduce the pressure on the legs.

[0009] The walking assembly includes a conveying motor and two rectangular tubes, the two rectangular tubes are fixed on the sides of the U-shaped plate, a bottom plate is fixed between the two rectangular tubes, a baffle is fixed above the two rectangular tubes, two conveying rollers are rotatably arranged between the two rectangular tubes, a conveyor belt is arranged on the two conveying rollers, a number of support rollers are fixed between the two rectangular tubes, and the several support rollers are located below the conveyor belt. The conveying motor is fixed inside one of the rectangular tubes, and the output shaft of the conveying motor is connected to one of the conveying rollers through a coupling.

[0010] With the above structure, the conveying motor drives one of the conveying rollers to rotate through the output shaft, and the conveying roller drives the conveyor belt to rotate. Several support rollers can support the conveyor belt, and two baffles can support both sides of the conveyor belt.

[0011] The support assembly includes two internally threaded columns, both of which are fixed on top of the rectangular tube. The interiors of the two internally threaded columns are threadedly connected to externally threaded columns, a rotating ring is fixed on the externally threaded columns, and an armrest is fixed above the two externally threaded columns, with rounded corners on the armrest.

[0012] With the above structure, the rotating ring is rotated, and the rotating ring drives the external thread column to rotate, thereby driving the external thread column to rise, and the external thread column drives the handrail to rise and adjust to the appropriate height.

[0013] Compared with the existing technology, this auxiliary weight-reduction device for lower limb rehabilitation training has the following advantages:

[0014] Through the coordination of the weight-reducing component, the walking component and the supporting component, the armpit support plate clamps and limits the chest and abdomen of the rehabilitation personnel, making it easier for the patient to control the center of gravity of the body. The electric push rod extends to drive the lifting block to rise, and the lifting block drives the two fixed columns to rise. The fixed columns drive the two armpit support plates to rise to the appropriate position to support the rehabilitation personnel's armpits and reduce the pressure on the legs. The armrests are convenient for the rehabilitation personnel to hold and support, making it easier for the patient to control the gravity borne by the lower limbs, thereby improving the effect of rehabilitation training.
