Description

Adjustable lower limb functional rehabilitation device

Technical Field

The utility model relates to the technical field of training equipment, in particular to an adjustable lower limb function rehabilitation equipment.

Background Art

Lower limb functional rehabilitation refers to rehabilitation treatment for motor dysfunction or injury of the lower limbs to help restore or improve the patient's lower limb motor ability and function. The goal of lower limb functional rehabilitation is to promote the recovery and adaptation of the patient's nervous, muscular and skeletal systems, while improving the patient's lower limb strength, coordination, balance and gait control. Patients with hemiplegia caused by cerebrovascular disease, leg movement disorders caused by trauma, lower limb muscle atrophy caused by motor neuron disease, etc. usually require lower limb rehabilitation training as an auxiliary treatment.

The Chinese patent document with the publication number CN212854501U discloses a combined all-round lower limb function exercise rehabilitation device, which includes a rolling ring and a carrying strap. The rolling ring includes a roller, and the roller is a cylindrical structure with a hollow interior and openings at both ends. The two ends of the roller are installed with circular plates, and the center position of the circular plate is provided with a perforation, and the perforation is connected to the inside of the roller. The upper and lower ends of the roller are symmetrically provided with an upper foot fixing belt and a lower foot fixing belt. The carrying strap passes through the interior of the roller, and the two ends of the carrying strap pass through the perforations of the circular plates on both sides. With respect to the above technical scheme, there are the following defects in use: the existing technology completely relies on the user's own strength to exercise, and also requires the upper limbs to cooperate in operation. In the process of lower limb function recovery, soreness and fatigue will occur, which makes it difficult for users to persist for a long time, making the exercise effect less than ideal.

For this purpose, an adjustable lower limb function rehabilitation device is proposed.

As shown in FIG1 , an adjustable lower limb functional rehabilitation device comprises a seat 1, wherein the front and back sides of the seat 1 are both rotatably connected with a rotating column 2, a spacing adjustment component 3 is provided on the surface of the rotating column 2, a connecting column 4 is provided on the surface of the spacing adjustment component 3, a passive exercise component 5 is provided on the surface of the connecting column 4, a locking mechanism 6 for limiting the rotating column 2 is provided on the surface of the seat 1, and a holding mechanism 7 is also provided on the surface of the seat 1. More specifically, a user sits on the surface of the seat 1, and places his feet on the surface of the passive exercise component 5. The passive exercise component 5 drives the feet to move periodically, so that the user's legs are constantly bent and straightened, thereby helping the user to perform passive exercise on the lower limbs. The locking mechanism 6 releases the limit on the rotating column 2, so that the rotating column 2 can rotate freely. At this time, the user's feet are placed under the passive exercise component 5, and the passive exercise component 5, the connecting column 4, the spacing adjustment component 3 and the rotating column 2 are driven to rotate by the leg force, so as to perform active exercise. The length of the device can be adjusted by the spacing adjustment component 3, which is suitable for users with different leg lengths. The holding mechanism 7 can protect the user in exercise.

As shown in Figures 1 and 2, the spacing adjustment component 3 includes a sleeve 301, and the sleeve 301 is slidingly connected to the surface of the rotating column 2, and the end of the connecting column 4 is fixedly connected to the sleeve 301. The right side of the sleeve 301 is threadedly connected with a first adjusting screw 302, and the first adjusting screw 302 is rotatably connected to the rotating column 2, and the right end of the first adjusting screw 302 is fixedly connected with a first knob 303. It should be noted that by rotating the first knob 303, the first adjusting screw 302 is driven to rotate, and under the action of the thread, the sleeve 301 is driven to slide along the surface of the rotating column 2, thereby adjusting the position of the connecting column 4 and the passive exercise component 5, so that the device is suitable for users with different leg lengths.

As shown in Figure 1, the passive exercise component 5 includes an electric push rod 501, and the electric push rod 501 is fixedly installed on the right side of the connecting column 4. The telescopic end of the electric push rod 501 is fixedly connected to an L-shaped shelf 502. The right side of the L-shaped shelf 502 is fixedly connected to a limiting column 503, and the limiting column 503 is movably connected to the connecting column 4. More specifically, the user's feet are placed on the surface of the L-shaped shelf 502, and the electric push rod 501 is driven to periodically extend and shorten its telescopic end, thereby pushing the L-shaped shelf 502 to periodically move left and right, driving the user's feet to move, so that the user's legs are constantly bent and restored, thereby performing passive exercise, and the L-shaped shelf 502 is strengthened and supported by the limiting column 503.

As shown in Figure 3, the left side of the L-shaped shelf 502 is fixedly connected with an anti-slip pad 504, and the bottom surface of the L-shaped shelf 502 is fixedly connected with a soft pad 505, and the anti-slip pad 504 and the soft pad 505 are both made of rubber. It should be noted that by providing the anti-slip pad 504 made of rubber, the user's feet are placed more stably on the surface of the L-shaped shelf 502 and are not easy to slip, and by providing the soft pad 505, the contact with the user's instep is more comfortable.

As shown in Figures 2 and 4, the locking mechanism 6 includes a bent rod 601, and the bent rod 601 is fixedly connected to the side of the seat 1. A second adjusting screw 602 is threadedly connected to the surface of the bent rod 601, one end of the second adjusting screw 602 is fixedly connected to a second knob 603, and the other end of the second adjusting screw 602 is rotatably connected to an insert block 604. An alignment groove 605 is provided on the surface of the rotating column 2, and the inner wall of the alignment groove 605 is movably connected to the end of the insert block 604. More specifically, by rotating the second knob 603, the second adjusting screw 602 is driven to rotate. Under the action of the thread, the second adjusting screw 602 rotates and moves along the surface of the bent rod 601, thereby driving the insert block 604 to move, so that the insert block 604 is separated from the inner wall of the alignment groove 605, and the limit on the rotating column 2 can be released, and the rotating column 2 can rotate freely.

As shown in Figure 1, the holding mechanism 7 includes a guardrail 701, and the number of guardrails 701 is two, and the two guardrails 701 are fixedly connected to the seat 1, and a fixing rod 702 is fixedly connected to the top of the guardrail 701. It should be noted that by setting two guardrails 701, the two sides of the user are protected, and by setting the fixing rod 702, the user can grasp it, which is convenient for exerting force during exercise.

To sum up: the user sits on the surface of the seat 1 and places the feet on the surface of the passive exercise component 5. The passive exercise component 5 drives the feet to move periodically, so that the user's legs are constantly bent and straightened, thereby helping the user to passively exercise the lower limbs. The locking mechanism 6 releases the limit on the rotating column 2, so that the rotating column 2 can rotate freely. At this time, the user's feet are placed under the passive exercise component 5, and the passive exercise component 5, the connecting column 4, the spacing adjustment component 3 and the rotating column 2 are driven to rotate by the leg force, so as to perform active exercise. The length of the device can be adjusted by the spacing adjustment component 3, which is suitable for users with different leg lengths. The holding mechanism 7 can protect the user during exercise, and the goal of facilitating the exercise of the user's lower limbs is achieved during use. The combination of active and passive exercise effectively improves the exercise effect, and it is easier for users to persist in exercise, which is more practical.
