Abstract
Description
Technical Field
[0001] This utility model relates to the field of cervical spine rehabilitation and nursing technology, specifically to a cervical spine traction rehabilitation training device. Background Technology
[0002] Cervical spondylosis is a common spinal disease, mainly caused by degenerative changes in the cervical intervertebral discs, cervical osteophyte formation, or alterations in the normal physiological curvature of the cervical spine. This leads to irritation or compression of the cervical nerve roots, spinal cord, vertebral artery, and cervical sympathetic nerves, resulting in a series of symptoms. Symptoms are diverse, including neck pain, stiffness, limited range of motion, shoulder and back pain, numbness in the hands, upper limb weakness, dizziness, headache, and blurred vision. Depending on the location of compression, cervical spondylosis can be classified into cervical type, nerve root type, spinal cord type, vertebral artery type, sympathetic nerve type, and mixed type. Prevention and relief of cervical spondylosis include improving lifestyle habits, such as avoiding prolonged periods of working with the head down, maintaining correct sitting and sleeping postures; appropriate neck stretching, swimming, Tai Chi, and other exercises; and relieving symptoms through physical therapy such as hot compresses, physiotherapy, and massage. In severe cases, medication or surgery may be necessary.
[0003] Traditional traction devices are not convenient for users to adjust their neck rehabilitation training themselves. Patients often need to remove the neck support pad for adjustment, which is not convenient for users to adjust their neck rehabilitation training themselves. They are not suitable for users with different cervical vertebrae lengths. Furthermore, maintaining the same head height for a long time during cervical rehabilitation training can easily cause cervical fatigue, leading to discomfort for patients. In some cases, excessive cervical traction force can even aggravate cervical injuries, causing damage to the patient's cervical spine. Utility Model Content

[0014] As a further embodiment of this utility model, a cushion is provided on the top of the seat plate, and armrests are fixed on both sides of the cushion.
[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0016] (1) In use, the user sits on the seat and rests their neck against the neck support. By simply rotating the lever, the cam drives the first rotating wheel to rotate, causing the rope wound on the first rotating wheel to wind up. Then, through the second rotating wheel and the fixed pulley, the movable pulley is lifted, thereby driving the toothed plate to rise. The toothed plate then drives the L-shaped sliding plate to rise. The toothed plate and the toothed plate mesh, and as the L-shaped sliding plate rises, the extension frame moves upward, causing the neck support to move upward with the extension frame. This precisely generates an upward force on the user's head and neck, thus achieving… The device provides appropriate traction to the user's neck. After rotating the lever to a certain extent, the other hand grasps the push rod and moves it backward. This push rod then drives the L-shaped rod and the limiting rod backward. At this point, the limiting rod abuts against the gear, preventing the gear from rotating. The gear, in turn, prevents the gear plate from moving. This operation allows for continuous traction for the user's cervical spine rehabilitation training without the need to remove the neck support pad for adjustment. This allows users to easily adjust the degree of cervical rehabilitation training themselves, making it more suitable for users with different cervical spine lengths and well meeting their needs.
[0017] (2) After the patient feels discomfort, hold the push rod with one hand and move it forward. At this time, the push rod will drive the L-shaped rod and the limiting rod to move forward. At this time, the limiting rod and the gear will not be in contact. The other hand rotates the rotating rod, which will move the traction mechanism downward. The tension on the user's neck will also disappear, so as to relieve the patient's discomfort in time and avoid the situation of aggravating the cervical spine injury caused by excessive traction force. This will improve the efficiency of the auxiliary rehabilitation of the user's cervical spine and effectively avoid the damage to the patient's cervical spine caused by the cervical traction device.

[0029] When in use, the user sits on the seat 1 and only needs to turn the lever 7 by hand. At this time, the cam 6 drives the first wheel 28 to rotate, and the rope 21 wound on the first wheel 28 will be wound up.
[0030] The pulley assembly includes a fixed pulley 12, a movable pulley 13, and a second hook 15. The fixed pulley 12 is fixed at the bottom of the support platform 2, the movable pulley 13 is located below the fixed pulley 12, and the second hook 15 is fixed at the bottom of the movable pulley 13.
[0031] The rope 21 is first wound around the first rotating wheel 28, and then successively wound around the second rotating wheel 9, the fixed pulley 12, the movable pulley 13, and finally fixed to the first hook 14.
[0032] The traction mechanism includes a toothed plate 17, an L-shaped sliding plate 20, an extension frame 22, a Y-shaped connecting frame 23, a hook 24, a hanging ring 25, and a neck support pad 26. The toothed plate 17 is slidably disposed inside the support platform 2. A third hook 33 is fixed to the top of the toothed plate 17. The second hook 15 and the third hook 33 are connected by a rope 27. An L-shaped sliding plate 20 is fixed to one side of the toothed plate 17. The L-shaped sliding plate 20 is slidably disposed inside the support platform 2. An extension frame 22 is fixed to one side of the L-shaped sliding plate 20. The extension frame 22 is located above the support platform 2. The extension frame 22 passes through the bottom of the support platform 2 and is fixed to a Y-shaped connecting frame 23. Hooks 24 are symmetrically fixed to both sides of the Y-shaped connecting frame 23. A hanging ring 25 is hung on the hook 24. A neck support pad 26 is fixed to the bottom of the hanging ring 25.
[0033] Specifically, the movable pulley 13 is then lifted by the second rotating wheel 9 and the fixed pulley 12, thereby driving the toothed plate 17 to rise. The toothed plate 17 drives the L-shaped sliding plate 20 to rise. The toothed plate 17 and the toothed plate 18 mesh. When the L-shaped sliding plate 20 rises, it drives the extension frame 22 to move upward, so that the neck support pad 26 moves upward with the extension frame 22, thereby accurately generating an upward force on the user's head and neck, thereby achieving appropriate stretching of the user's neck.
[0034] Two limiting plates 16 are fixed on the side of the support platform 2 facing the seat plate 1. The two limiting plates 16 are symmetrically arranged, and a gear 18 is rotatably arranged between the two limiting plates 16. The gear 18 meshes with the toothed plate 17.
[0035] An extension platform 29 is fixed on the side of the seat plate 1 away from the winding assembly. A slot 30 is provided on the extension platform 29.

The L-shaped rod 32 is fixed to the limiting rod 19, and the limiting rod 19 slides in the sliding groove.
[0036] When in use, after rotating the lever 7 to a certain extent, the other hand holds the push rod 31 and moves it backward. At this time, the push rod 31 will drive the L-shaped rod 32 and the limiting rod 19 to move backward. At this time, the limiting rod 19 abuts against the gear 18, preventing the gear 18 from rotating. The gear 18 prevents the toothed plate 17 from moving. This operation can continuously traction the user for cervical spine rehabilitation training without removing the neck support pad for adjustment. It is convenient for users to adjust the degree of cervical rehabilitation training themselves, and can be better suited for users with different cervical spine lengths, thus well meeting people's needs.
[0037] Working principle:
[0038] In use, the user sits on the seat 1, resting their neck against the neck support 26. By turning the lever 7, the cam 6 drives the first rotating wheel 28 to rotate, causing the rope 21 wound on the first rotating wheel 28 to wind up. This winds up the rope through the second rotating wheel 9 and the fixed pulley 12, lifting the movable pulley 13, which in turn raises the toothed plate 17. The toothed plate 17 then raises the L-shaped sliding plate 20. The toothed plates 17 and 18 mesh, and as the L-shaped sliding plate 20 rises, the extension frame 22 moves upward, causing the neck support 26 to move upward with the extension frame 22, thus precisely providing upward support for the user's head and neck. The force is applied to provide appropriate stretching for the user's neck. After the hand rotates the lever 7 to a certain extent, the other hand holds the push lever 31 and moves it backward. At this time, the push lever 31 will drive the L-shaped lever 32 and the limiting lever 19 to move backward. At this time, the limiting lever 19 abuts against the gear 18, preventing the gear 18 from rotating. The gear 18 prevents the toothed plate 17 from moving. This operation can continuously traction the user for cervical spine rehabilitation training without removing the neck support pad for adjustment. It is convenient for the user to adjust the degree of cervical rehabilitation training by themselves, which can better suit users with different cervical spine lengths and well meet people's needs.
[0039] After the patient feels discomfort, one hand holds the push rod 31 and moves it forward. At this time, the push rod 31 will drive the L-shaped rod 32 and the limiting rod 19 to move forward. At this time, the limiting rod 19 and the gear 18 are not in contact. The other hand rotates the rotating rod 7, which moves the traction mechanism downward. The tension on the user's neck will also disappear, so as to relieve the patient's discomfort in time and avoid aggravating the cervical spine injury caused by excessive traction force. This improves the efficiency of the auxiliary rehabilitation of the user's cervical spine and effectively avoids damage to the patient's cervical spine caused by the cervical traction device.
