Description

Technical Field

[0001] This utility model relates to the field of rehabilitation training technology, and in particular to a multifunctional roller. Background Technology

[0002] Occupational therapy rollers are tools used to train balance and coordination in patients with motor disorders such as hemiplegia and cerebral palsy. They are primarily long, cylindrical objects that can be rolled. Occupational therapy roller exercises relieve muscle spasms, expand range of motion, improve balance and coordination, and promote protective postural responses and head lifting in children with cerebral palsy. Research shows that rollers on the market are generally categorized by size and firmness to achieve the desired rehabilitation goals for patients.

[0003] The published patent document CN218187252U discloses a multifunctional rehabilitation therapy roller, relating to the field of rehabilitation training technology. This utility model includes a bottom fixing plate, with rehabilitation rollers disposed at both ends of the top of the bottom fixing plate, and an adjustment mechanism for adjusting the distance between the two rehabilitation rollers disposed at one end of the top of the bottom fixing plate.

[0004] However, the existing technology has its shortcomings in use. The rehabilitation roller in the existing technology cannot be disassembled, so it is inconvenient for medical staff to disassemble and clean it after long-term use. Moreover, it cannot be replaced when damaged, which will affect subsequent normal use. Therefore, we propose a multi-functional roller. Utility Model Content

[0029] like Figure 1-6 As shown, this utility model provides a multifunctional roller, including a base 7. A limiting groove 15 is provided in the middle of the upper surface of the base 7. Two threaded sliders 9 are slidably connected inside the limiting groove 15. An installation frame 5 is fixedly connected to the upper end of the threaded sliders 9. A rehabilitation roller 10 is arranged inside the installation frame 5. A rotating rod 1 is provided at both ends of the rehabilitation roller 10, passing through the installation frame 5 and rotatably connected to the passing part through the bearing. A frame 2 is fixedly connected to one end of the rotating rod 1. A square block 4 is slidably connected inside the frame 2. One end of the square block 4 is fixedly connected to the rehabilitation roller 10. The square block 4 and the frame 2 are connected by a limiting mechanism.

[0030] Preferably, the upper surface of the base 7 has two limiting slide grooves 14, and two limiting sliders 6 are slidably connected inside the limiting slide grooves 14 and are respectively fixedly connected to the corresponding mounting brackets 5. The limiting sliders 6 can cooperate with the limiting slide grooves 14 to allow the mounting brackets 5 to slide in a limited manner.

[0031] Preferably, the limiting slide groove 15 is provided with a bidirectional screw 16 that passes through the two threaded sliders 9 and is threadedly connected to the through part. The bidirectional screw 16 passes through the base 7 and is rotatably connected to the through part by a bearing. The bidirectional screw 16 can make the two threaded sliders 9 move in opposite directions, thereby making the two rehabilitation rollers 10 move in opposite directions, which facilitates the adjustment of the working distance between the two rehabilitation rollers 10.

[0032] Preferably, one end of the bidirectional lead screw 16 is provided with a mounting cover 8 that is fixedly connected to the base 7. A bidirectional motor 22 is fixedly connected inside the mounting cover 8. The output end of the bidirectional motor 22 is fixedly connected to one end of the bidirectional lead screw 16. The bidirectional motor 22 can enable the bidirectional lead screw 16 to rotate in both directions.

[0033] Preferably, each of the two mounting brackets 5 is fixedly connected to an L-shaped bracket on one side, and a rotary motor 13 is fixedly connected inside the L-shaped bracket. A gear 12 is fixedly connected to the output end of the rotary motor 13. A gear 11 that meshes with the gear 12 is provided on the upper end of the gear 12. The gear 11 is fixedly connected to one end of the corresponding rotating rod 1.

[0034] Preferably, the limiting mechanism includes a movable groove 17 formed on the surface of the square insert 4, a telescopic cylinder 18 is fixedly connected inside the movable groove 17, and a push plate 3 is fixedly connected to the output end of the telescopic cylinder 18 and slidably connected inside the movable groove 17. The push plate 3 can drive the positioning rod 20 to move.

[0035] Preferably, the surface of the telescopic cylinder 18 is fitted with a spring 19, the two ends of which are fixedly connected to the push plate 3 and the inner side of the movable groove 17 respectively. The push plate 3 is fixedly connected to a positioning rod 20 that passes through the square insert 4 and is slidably connected to the through part. The positioning rod 20 is slidably connected to the positioning hole 21 opened in the inner surface of the insert frame 2. The positioning rod 20 can be set to cooperate with the positioning hole 21 to limit the connection between the square insert 4 and the insert frame 2.

[0036] The specific working principle and usage method of this utility model are as follows:

[0037] This utility model provides a multifunctional roller. In use, it is powered by an external power source, and the bidirectional motor 22 causes the bidirectional lead screw 16 to rotate in both directions, so that the two threaded sliders 9 can move in opposite directions. This allows for adjustment of the distance between the two rehabilitation rollers 10, enabling rehabilitation treatment for legs of different diameters. Then, by starting the rotary motor 13, the gear 2 12 drives the gear 11 to rotate, thereby rotating the rehabilitation roller 10 and providing rehabilitation treatment for the patient's leg.

[0038] When the rehabilitation roller 10 needs to be disassembled, push the push plates 3 at both ends of the rehabilitation roller 10 with both hands simultaneously. Under the action of the telescopic cylinder 18, the push plates 3 slide within the movable groove 17, thereby causing the push plates 3 to separate the positioning rod 20 from the positioning hole 21. After separation, the square insert 4 can be removed from the insert frame 2, thus completing the disassembly of the rehabilitation roller 10. This allows the staff to clean the rehabilitation roller 10 or replace any damaged rehabilitation roller 10. For installation, push the push plates 3 as described above, causing the positioning rod 20 to slide into the square insert 4. At this time, the spring 19 is in a compressed state. Then, insert the square insert 4 into the insert frame 2. By releasing the push plates 3, the compressed spring 19 extends and returns to its original position, causing the push plates 3 to slide the positioning rod 20 in the opposite direction, allowing the positioning rod 20 to slide into the positioning hole 21. This places the square insert 4 in the insert frame 2, thus completing the limited installation of the rehabilitation roller 10.

[0039] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are equivalent embodiments of this utility model.
