[0002] Cervical traction is a common physical therapy used to relieve cervical muscle tension and pain. The basic principle is to apply external force to the cervical spine, causing moderate stretching and thereby alleviating symptoms of cervical spondylosis. A cervical traction chair is a device used to provide cervical traction therapy.
[0003] Although the existing cervical traction chairs meet the basic cervical traction needs in terms of functionality during use, there are still some deficiencies in the detailed design. Among them, one of the most obvious problems is the backrest adjustment mechanism. The backrest design of many cervical traction chairs is fixed and cannot be adjusted individually according to the user's waist and back curvature, which makes the user feel insufficient waist and back support during long-term use. Especially when performing long-term cervical traction, the waist and back muscles may need to bear additional pressure, causing discomfort or even injury; secondly, the existing cervical traction chairs are often designed with emphasis on their functionality and therapeutic effects, but there are some deficiencies in practicality. Among them, a significant problem is that some cervical traction mounts cannot be disassembled. When the cervical traction mounts are not needed, they cannot be converted into ordinary chairs, which limits their use scenarios in daily life. Utility Model Content

[0031] The seat 1 is provided with two limiting holes 12, and a limiting rod 13 is movably provided in each limiting hole 12. The upper ends of the two limiting rods 13 pass through the limiting holes 12 and are fixedly connected to a positioning plate 14. One end of the positioning plate 14 is fixedly connected to a traction frame 15, and a traction belt 16 is movably provided on the traction frame 15.
[0032] In this embodiment, when it is necessary to adjust the position of the lumbar pad 11 according to the user's height and back curvature, the user sits on the seat 1 and turns the handle 6 with one hand. The handle 6 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the driving bevel gear 7 to rotate. Since the driving bevel gear 7 is meshed with the driven bevel gear 8, the driving bevel gear 7 drives the driven bevel gear 8 to rotate, and the driven bevel gear 8 drives the screw 3 to rotate. Since the screw 3 is threadedly connected to the adjustment seat 9, the two adjustment seats 9 move at the same time, the adjustment seat 9 drives the adjustment plate 10 to move, and the adjustment plate 10 drives the lumbar pad 11 to move, thereby adjusting the position of the lumbar pad 11.
[0033] More specifically, the position of the lumbar pad 11 can be adjusted by rotating the two screw rods 3 by turning the handle 6. The traction frame 15 is moved, which drives the positioning plate 14 and the two limiting rods 13 to move. The two limiting rods 13 are inserted into the two limiting holes 12. The positioning plate 14 moves to the upper end of the seat 1 to limit the limiting rods 13 and the traction frame 15. At this time, the traction frame 15 is installed on one side of the chair.
[0034] See also Figure 1-5 , as an embodiment of fixing the traction frame 15: one side of the seat 1 is recessed inward to form a fixing chamber 17, a bidirectional screw 18 is rotatably provided in the fixing chamber 17, one end of the bidirectional screw 18 passes through the fixing chamber 17 and is fixedly connected to a handle 19, two fixing seats 20 are threadedly connected to the bidirectional screw 18, one end of each fixing seat 20 passes through the fixing chamber 17 and is fixedly connected to an L-shaped fixing block 21, one end of the fixing block 21 is inserted into the traction frame 15, two transmission rollers 22 are rotatably provided on the traction frame 15, two support plates 23 are fixedly provided on one side of the traction frame 15, two A winding roller 24 is rotatably provided between the support plates 23, and a motor 25 is fixedly provided on one of the support plates 23. The driving end of the motor 25 passes through the support plate 23 and is fixedly connected to the winding roller 24. A traction rope 26 is wound around the winding roller 24, and one end of the traction rope 26 is fixedly connected to the winding roller 24. The traction rope 26 is movably connected to the two winding rollers 24, and the other end of the traction rope 26 is fixedly connected to a mobile frame 27. The traction belt 16 is installed on the mobile frame 27. An L-shaped support frame 28 is fixedly provided on one side of the traction frame 15, and a controller 29 is installed on the support frame 28.
[0035] Specifically, when the traction frame 15 is attached to one side of the chair, turning the handle 19 rotates the bidirectional lead screw 18. The lead screw 18 has two threaded areas running in opposite directions, causing the two fixing seats 20 to move in adjacent directions. The fixing seats 20 then move the fixing blocks 21. The traction frame 15 has two fixing slots on either side, into which the fixing blocks 21 fit, securing the traction frame 15. When the traction chair is no longer needed, the traction frame 15 can be removed, converting it into a standard chair. The controller 29 activates the motor 25, which rotates the winding roller 24. The winding roller 24 winds the traction rope 26 around it. The two drive rollers 22 rotate, and the traction rope 26 drives the moving frame 27 and the traction belt 16 to move, thereby adjusting the position of the traction frame 15. Once adjusted, the user can use the traction belt 16 to traction their cervical spine.
[0036] See also Figure 1-5As an implementation method for fixing the patient's waist and back: straps 30 are fixed on both sides of the adjustment plate 10, one of the straps 30 is provided with two matching Velcros 31, and the other strap 30 is fixed with a connecting ring 32.

[0038] In summary, when the overall equipment is in use:
[0039] When the traction frame 15 needs to be installed on the chair 1, the traction frame 15 is moved, which drives the positioning plate 14 and the two limiting rods 13 to move. The two limiting rods 13 are inserted into the two limiting holes 12. The positioning plate 14 moves to the upper end of the chair 1 to limit the limiting rods 13 and the traction frame 15. At this time, the traction frame 15 is installed on one side of the chair. The handle 19 is turned, and the handle 19 drives the bidirectional screw 18 to rotate. The bidirectional screw 18 has two threaded areas in opposite directions, which causes the two fixing seats 20 to move in adjacent directions. The fixing seats 20 drive the fixing blocks 21 to move. The two fixing grooves on both sides of the traction frame 15 are inserted into the fixing grooves, thereby fixing the traction frame 15. When the entire traction chair is no longer needed, the traction frame 15 can be disassembled, so that the entire traction chair can be used as a normal chair. The controller 29 controls the motor 25 to start, which drives the winding roller 24 to rotate. The winding roller 24 winds the traction rope 26 around the winding roller 24, and the two driving rollers 22 rotate. The traction rope 26 drives the moving frame 27 and the traction belt 16 to move, thereby adjusting the position of the traction frame 15. After the adjustment is completed, the user can use the traction belt 16 to traction the cervical spine.
[0040] When it is necessary to adjust the position of the lumbar pad 11 according to the user's height and back curvature, the user sits on the seat 1 and turns the handle 6 with one hand. The handle 6 drives the rotating rod 5 to rotate, and the rotating rod 5 drives the driving bevel gear 7 to rotate. Since the driving bevel gear 7 is meshed with the driven bevel gear 8, the driving bevel gear 7 drives the driven bevel gear 8 to rotate, and the driven bevel gear 8 drives the screw 3 to rotate. Since the screw 3 is threadedly connected to the adjustment seat 9, the two adjustment seats 9 move at the same time, the adjustment seat 9 drives the adjustment plate 10 to move, and the adjustment plate 10 drives the lumbar pad 11 to move, thereby adjusting the position of the lumbar pad 11.
[0041] When the user's waist and back need to be fixed, one end of one of the straps 30 is passed through the connecting ring 32, and then the two Velcro strips 31 are fixed together to fix the user's waist and back.
