AI Technical Summary
The existing spinal care devices lack a limiting mechanism after adjusting the backplane angle, which leads to the backplane angle being easily affected by human pressure and lack of applicability.
A spinal care device including an adjustment mechanism and a fixing mechanism is designed to adjust the backplate height by a sliding assembly and a rotating assembly, and to prevent changes in the backplate angle using a spring fixing mechanism.
It achieves height adjustment adaptability to different groups of people, ensuring that the back plate maintains a stable angle during use and does not change due to human pressure.

Technical Field
[0001] The utility model relates to the technical field of medical appliances, in particular to a traction device for spinal care and rehabilitation. Background Technique
[0002] The human spine is composed of 33 vertebrae (7 cervical vertebrae, 12 thoracic vertebrae, 5 lumbar vertebrae, and a total of 9 sacral and coccygeal vertebrae) connected by ligaments, joints, and intervertebral discs. The upper end of the spine supports the skull, the lower end is connected to the hip bone, and the ribs are attached in the middle, and it serves as the posterior wall of the chest cavity, abdominal cavity, and pelvic cavity. The spine has the functions of supporting the trunk, protecting internal organs, protecting the spinal cord, and enabling movement. A longitudinal spinal canal is formed from top to bottom inside the spine, and the spinal cord is inside. The spine is the pillar of the body, located in the middle of the back, with the upper end connected to the skull and the lower end reaching the tip of the coccyx. The spine is divided into five sections: cervical, thoracic, lumbar, sacral, and coccygeal. The upper part is long and movable, like a bracket, hanging the chest wall and abdominal wall; the lower part is short and relatively fixed, and the weight and shock of the body are transmitted to the lower limbs through this. The spine is composed of vertebrae and intervertebral discs and is a relatively flexible and movable structure.

[0027] The present invention provides the following technical solutions:
[0028] Embodiment 1
[0029] Please refer to Figures 1-3 , a traction device for spinal care rehabilitation, including a backboard 1 and a base 2. Adjusting mechanisms 3 are provided on the left and right sides of the base 2, and fixing mechanisms 4 are provided on the left and right sides of the front of the base 2;
[0030] The adjusting mechanism 3 includes a sliding component 31 and a rotating component 32. The sliding component 31 is provided on the left and right sides of the base 2, and the rotating component 32 is provided on the top of the sliding component 31.
[0031] The sliding component 31 includes a connecting block 311. The connecting block 311 is fixedly connected to both ends of the backboard 1. A first connection hole 312 is opened on the front of the connecting block 311. Sliding grooves 313 are opened on the left and right sides of the base 2. A sliding plate 314 is slidably connected in the sliding grooves 313. A connecting rod 315 is fixedly connected to the side of the sliding plate 314 close to the backboard 1.
[0032] Both ends of the connecting rod 315 are inserted into the first connection hole 312. By sliding the sliding plate 314 in the sliding groove 313, the height of the backboard 1 can be adjusted to adapt to different types of people.
[0033] The rotating component 32 includes a rectangular groove 321. The rectangular grooves 321 are symmetrically opened on the left and right sides of the top of the base 2. A connecting plate 322 is slidably connected in the rectangular groove 321. A threaded hole 323 is opened on the right side of the connecting plate 322. The connecting plate 322 is rotationally connected to a bidirectional threaded rod 324 through the threaded hole 323. Limit blocks 325 are fixedly connected to both ends of the bidirectional threaded rod 324.
[0034] The bottom of the rectangular groove 321 penetrates through to the inside of the sliding groove 313. The bottom of the connecting plate 322 is fixedly connected to the top of the sliding plate 314. The two threaded holes 323 are mirror-symmetrical. By rotating the bidirectional threaded rod 324, the two sliding plates 314 slide within the sliding groove 313, and the limiting block 325 prevents the bidirectional threaded rod 324 from moving out of the threaded hole 323.
[0035] Embodiment 2
[0036] Please refer to Figures 4-6 , and on the basis of Embodiment 1, the fixing mechanism 4 is further obtained.
[0037] The fixing mechanism 4 includes a first connection port 41. The connection ports are symmetrically opened on the left and right sides of the front of the base 2. The second connection port 42 is correspondingly opened on the front of the sliding plate 314 opposite to the first connection port 41. A plug rod 43 is slidably connected within the first connection port 41. Sliding grooves 44 are opened on the left and right sides inside the front of the base 2. A sliding block 45 is fixedly connected to the surface of the plug rod 43. Second connection holes 46 are symmetrically opened on the left and right sides of the front of the sliding block 45. A guide rod 47 is slidably connected within the second connection hole 46. A spring 48 is sleeved on the surface of the guide rod 47 within the sliding block 45 and the sliding groove 44.
[0038] The first connection port 41 penetrates through to the inside of the sliding groove 44. The rear end of the plug rod 43 is inserted into the second connection port 42. The sliding block 45 is slidably connected within the sliding groove 44. The front end of the spring 48 is fixedly connected to the front inside the sliding groove 44, and the rear end of the spring 48 is fixedly connected to the front of the sliding block 45. The rear end of the plug rod 43 is inserted into the second connection port 42 by the elastic force of the spring 48 to fix the sliding plate 314, preventing the adjusted back panel 1 from changing its bending degree due to pressure during the use of the device.
[0039] During the actual operation process, when this device is in use, by rotating the bidirectional threaded rod 324, the two connecting plates 322 move, and the movement of the two connecting plates 322 moves the sliding plates 314 within the sliding groove 313, thereby adjusting the height of the back panel 1. This operation enables the device to be adjusted for different types of people, with strong applicability. Before adjusting the height of the back panel 1, first pull the plug rod 43 to make the rear end of the plug rod 43 move out of the second connection port 42, then adjust the height of the back panel 1. After adjustment, release the plug rod 43, and the rear end of the plug rod 43 will enter the corresponding second connection port 42 on the front of the sliding plate 314 due to the elastic force of the spring 48, thus completing the fixation of the back panel 1 and preventing the back panel 1 from changing its height due to the pressure released by people.
