Description

Technical Field

[0001] The invention relates to the technical field of rehabilitation for disabled persons, and in particular to a manual rehabilitation wheelchair for disabled persons. Background Art

[0002] A manual rehabilitation wheelchair for the disabled is an auxiliary mobility device designed for people with limited mobility to meet basic travel needs. Traditional manual wheelchairs mainly rely on the user's upper limbs to push the rear wheels or the caregivers to push the rear wheels to move forward. The method of pushing the rear wheels by hand cannot exercise the user's feet, and the method of others assisting in pushing forward by hand cannot provide rehabilitation training for the limbs. Due to the lack of effective rehabilitation training methods, users' long-term reliance on wheelchairs for movement can easily lead to gradual atrophy of limb muscles, stiff joints, and may even further weaken the already limited walking ability. Therefore, a manual rehabilitation wheelchair for the disabled is urgently needed to solve the above technical defects. Summary of the invention

[0003] The purpose of the present invention is to provide a manual rehabilitation wheelchair for the disabled to solve the problem of being unable to perform limb rehabilitation training proposed in the above-mentioned background technology.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a manual rehabilitation wheelchair for the disabled, comprising a seat and a backrest, a backrest welded to the rear end of the seat, a base frame fixedly connected to the bottom end of the seat, two sets of front wheels installed at the front end of the base frame, two sets of rear wheels installed at the rear end of the base frame, a mounting frame fixedly fixed at the middle position of the base frame, a leg rehabilitation component installed at the front end of the mounting frame, and a hand rehabilitation component installed on the outside of the mounting frame; the leg rehabilitation component comprises a group of mounting rods fixedly connected to the middle position of the mounting frame, a fixture fixedly connected to the bottom end of the mounting rod, a Mecanum wheel installed in the fixture, and a group of pedals are installed on the left and right sides of the fixture through bearings; the hand rehabilitation component comprises two groups of rotating rods movably assembled on both sides of the outside of the seat, a hand-cranked wheel is installed on the top of the rotating rod, a large chainring is installed at the center position of the rear wheel, a steering gear group is installed at the bottom of the rotating rod, and the steering gear group is connected to the large chainring of the rear wheel through a chain belt.

[0005] As a further technical solution of the present invention, the diameter of the Mecanum wheel is 30CM, and when the Mecanum wheel moves forward, backward, and rotates up and down in the fixture, the angle between the Mecanum wheel and the fixture does not exceed 15° to adapt to the slope.

[0006] As a further technical solution of the present invention, a plurality of groups of mounting holes are vertically arranged in the mounting rod, and mounting bolts are fixedly connected between the mounting frame and the mounting holes.

[0007] As a further technical solution of the present invention, a slot is provided inside the seat, and five groups of support plates are clamped in the slot, and a cushion or a toilet is placed on top of the support plate.

[0008] As a further technical solution of the present invention, an armrest is fixedly connected to the top of the seat, and a slot is provided on the inner side of the armrest, into which a dining board can be inserted.

[0009] As a further technical solution of the present invention, a hydraulic backrest is placed on the inner side of the chair back, and an adjustable headrest fixed in the chair back is arranged above the hydraulic backrest.

[0010] As a further technical solution of the present invention, the rear end of the hydraulic backrest is fixedly connected to two sets of telescopic cylinders, the telescopic cylinders are installed with locking bolts for adjusting their lengths, and the top of the telescopic cylinders is fixedly connected to the rear end of the adjustable headrest.

[0011] As a further technical solution of the present invention, the adjustable headrest is externally covered with a rain shield, and the rain shield can be folded on the top of the seat back.

[0012] Compared with the prior art, the invention has the following beneficial effects: the manual rehabilitation wheelchair for the disabled not only promotes rehabilitation training of the four limbs at the same time, enables eating or going to the toilet in the wheelchair, reduces the workload of the nursing staff, but also improves the comfort of use;
