[0040] The preferred embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0041] like Figures 1 to 4 As shown, a first embodiment of a spinal traction training device includes:

[0042] The main frame 1, as the main support structure of the entire device, includes a bottom 11 supported on the ground and a vertical part 12 extending vertically upward from the bottom. The vertical part 12 extends backward with two frames 13.

[0043] The backing plate 2 stands alongside the main frame 1 and has an opening 21 in the middle.

[0044] The movable rocker arm 3 is hinged to the upper end of the main frame 1, with the front part for the user to grip and the rear part connected to the traction rope;

[0045] The roller mechanism 4, used to adjust the direction of the traction force of the traction rope, is located at the rear of the main frame 1 and includes a roller 41 and a roller fixing rod 42. The roller fixing rod 41 passes through the shaft hole of the roller 41 and is fixed to the main frame 1.

[0046] The traction rope 5, with its upper end fixed to the movable rocker arm 3, passes around the roller 41 and through the opening 21 of the backrest 2, then wraps around the user's crotch and around the user's waist. Preferably, the traction rope splits into two strands at the part that wraps around the front of the user's body.

[0047] The height of the rollers can be adjusted according to different users' needs.

[0048] In one embodiment, each frame 13 is provided with a row of latches, and the height of each latch on one frame corresponds one-to-one with the height of each latch on another frame, forming multiple pairs of latches, each pair of latches being at the same height. When adjusting the height of the roller, the roller fixing rod 42 can select from multiple pairs of latches of different heights according to the user's needs, and the two ends of the roller fixing rod 42 are respectively locked into a pair of latches of the same selected height.

[0049] In another embodiment, each frame 13 is provided with a row of through holes 131. The height of each through hole in one frame corresponds one-to-one with the height of each through hole in another frame, forming multiple pairs of through holes, each pair of through holes being at the same height. When adjusting the height of the roller, the roller fixing rod 42 can be selected from multiple pairs of through holes of different heights according to the user's needs. The two ends of the roller fixing rod 42 are respectively fixed to the frame by means of screws 43 passing through a pair of through holes of the same height selected.

[0050] Preferably, the backrest is designed to conform to the curve of the human back. The height of the backrest can be adjusted according to the user's height, and the height adjustment can be achieved by a slot-type or an electric lifting type.

[0051] The movable rocker arm 3 is ring-shaped, with a mounting position 31 at the rear for fixing the upper end of the traction rope. The backrest is lower than the main frame, and the main frame has an opening AA at a position higher than the backrest.

[0052] This patented spinal traction training device features a backrest designed to fit flush against the human body, made of a rigid yet supportive material such as wood, to conform to the curve of the back and ensure user comfort and stability during traction. The movable rocker arm is made of lightweight, high-strength materials, such as aluminum alloy, and is hinged to the main frame via a flexible pivot, ensuring easy pulling by the user. The traction rope is made of a tough yet flexible material with a degree of elasticity.

[0053] When using, adjust the roller mechanism to the initial preset height according to the user's height, such as... Figure 4 As shown, firstly, the traction rope 5 is fixed at a suitable position at the rear end of the movable rocker arm. Then, the roller mechanism 4 is adjusted to a suitable position for the user. Next, the traction rope 5 is looped around the roller 41 and passed through the opening 21 on the backrest 2. The user stands in front of the backrest, the rope is looped up from under the user's crotch, and then tied around the user's waist. The tightness is adjusted to a comfortable level. Secondly, the traction operation is performed. The user lifts both hands and grasps the front of the rocker arm, slowly pulling downwards. Using leverage, the traction rope moves upwards under the guidance of the rollers, generating a forward traction force on the waist. The user can control the pulling amplitude and force according to their own tolerance. This traction training of the lumbar and sacral spine is achieved through the anterior-posterior action on the user's pelvis, improving the physiological curvature of the lumbar spine. The user can adjust the installation position of the upper end of the traction rope to a suitable position through the opening AA formed by the backrest and the main frame. Thirdly, traction adjustment: During the traction process, medical staff can adjust the direction of the traction force in real time according to user feedback and treatment needs, or the user can adjust the height of the roller mechanism themselves. Users can also stop or adjust the pulling operation as needed based on their own feelings. Finally, to end the operation and after the traction therapy is completed, the user releases the bar and unties the lumbar traction rope.

[0054] Considering that some users find it inconvenient to stand for long periods during traction, in some embodiments the entire device can be laid flat, allowing the user to lie flat on the device for stretching and traction. For example... Figure 7 As shown, the second embodiment of the spinal traction training device includes:

[0055] The main frame 1 includes a horizontal section and a vertical support section. The support section includes a floor stand 140, a reinforcing frame 141, and a silicone sleeve 142. These components are used to place the entire device on a flat surface. The floor stand 140 and the reinforcing frame 141 can be folded and movable for easy storage. The silicone sleeve 142 serves to prevent slippage and reduce noise.

[0056] The backing plate 2 is parallel to the horizontal part of the main frame, and the backing plate has an opening;

[0057] The movable rocker arm 3 is hinged to one end of the main frame 1, with the front part for the user to hold and the rear part connected to the traction rope;

[0058] Roller mechanism 4, located on the back of the main frame, is used to adjust the direction of the traction force of the traction rope;

[0059] The traction rope 5 is fixed to the movable rocker arm 3. It is used to go around the roller of the roller mechanism 4, pass through the opening of the backrest, go around the user's crotch, and then wrap around the user's waist. When the user controls the front of the rocker arm to pull, the traction rope 5 moves under the guidance of the roller and achieves traction training of the user's lumbar and sacral spine by acting on the user's pelvis from front to back.

[0060] Figure 1-4 The illustrated embodiments and Figure 7 The difference in the illustrated embodiment lies in whether the main frame is placed vertically or horizontally. Figure 1-4 It is placed vertically. Figure 7 It is placed horizontally. The main frame 1 can be... Figure 1-4 In this configuration, adding a floor stand 140, a reinforcing frame 141, and a silicone sleeve 142 transforms the device into a horizontally usable state. However, it can also be directly configured for horizontal use. In actual use, the user can replace the backrest 2 as needed. Preferably, the backrest 2 is the same height as the frame, thus allowing the device to be used in both vertical and horizontal positions simultaneously.

[0061] like Figures 8 to 10 As shown, the third embodiment of the spinal traction training device, based on the first embodiment, further includes a traction kit for longitudinal spinal stretching, suspended on the main frame. Specifically, the spinal traction training device includes a main frame 120, a backrest 2, a movable rocker arm 121, a roller mechanism 4, a traction belt 5, a compression spring 110, a chain 111, and a hanging strap 112.

[0062] The main frame 120, as the main support structure of the entire device, includes a bottom 11 supported on the ground and a vertical part 12 extending vertically upward from the bottom. The vertical part 12 extends backward with two vertical frames 13 and has a horizontal frame 107 extending forward at the upper end. The horizontal frame is provided with a hinge position 101 that is hinged to the movable rocker arm 121.

[0063] The backing plate 2 stands alongside the main frame 120 and has an opening 21 in the middle.

[0064] The movable rocker arm 121 is hinged to the frame extending forward at the upper end of the main frame 120. The front part is for the user to grip, and the rear part is connected to the traction belt. It is also provided with a hanging hole B, which is used to hang the compression spring 110. Preferably, the hanging hole B is located directly above the person's standing position.

[0065] The compression spring 110 has hooks at both the top and bottom ends. One end is hooked onto the hook hole B of the movable rocker arm 121, and the other end is hooked onto the chain 111.

[0066] The chain 111 is composed of multiple rings, which allow the user to adjust the hanging height.

[0067] The strap 112 can be worn on the user and its upper end is hooked onto the chain 111.

[0068] The traction kit is used for longitudinal stretching of the user's spine, and its usage method is as follows:

[0069] The user fastens the strap 112 to their upper body, then hooks the upper end of the strap 112 onto a suitable ring on the chain 111, adjusting it to the most comfortable position for traction and stretching. The user can grasp the front end of the movable rocker arm 121 and pull downwards. Because the hinge point between the movable rocker arm 121 and the main frame 120 forms a lever point, when the user pulls down, the rear of the movable rocker arm 121 tilts upwards, and the spring, under pressure, causes the user to move longitudinally for stretching—a very gentle stretching method. The user can also have someone else pull the front of the movable rocker arm 121 for stretching exercises.

[0070] This patented device can be used as training equipment for one step in a set of low back pain treatment and rehabilitation training methods, which specifically include the following steps:

[0071] Step 1: Use a vibration device to relax the femoral and pelvic joints and surrounding muscles and ligaments. For example... Figure 5 As shown, the trainee sits on a stool with hands resting on their thighs and leans forward. The trainee can adjust the seating position to a comfortable one. After adjusting, the feet are placed on the vibration device 300 to relax the femur, pelvic joint, and surrounding muscles and ligaments. This vibration device 300 can also be a common fat-burning machine, with a vibration frequency of 780 times / min and an amplitude of 2mm. The trainee can adjust the machine's setting according to their needs. The vibration relaxation time is 3-5 minutes, but the trainee can adjust the time based on their individual circumstances.

[0072] Step 2: Use a vibration device to relax the spinal joints, lower back muscles, and ligaments. For example... Figure 6 As shown, the trainee sits on the vibration device 300 with both feet placed at the front, body upright, and hands placed on the thighs and knees. The vibration relaxation time is 5-10 minutes, and the trainee can adjust the vibration relaxation time according to their own situation.

[0073] Step 3: Use the device of this invention to relax the joints, muscles, and ligaments connecting the pelvis and spine. For example... Figure 4As shown, after the trainee fixes one end of the traction rope to the upper part of the device, the height of the rear roller of the main frame is adjusted according to the user's height. Then, the traction rope is passed around the roller and extended out of the backrest opening. The trainee stands in front of the backrest, passes one end of the traction rope under the crotch and ties it to the waist. The trainee can grasp the front of the movable rocker arm with both hands, and the waist is pressed firmly against the backrest. The traction rope can be adjusted to a suitable position through the opening AA of the main frame. Then, the user can pull down the movable rocker arm with both hands. According to the lever principle, the rear of the movable rocker arm tilts upward, pulling the traction rope. The front of the traction rope tied to the trainee's waist is pulled downward, and the trainee's waist is pulled forward. The trainee can apply the force according to their own situation. The number of pulls is generally 30-50 times. The trainee can also adjust the number of pulls according to their own situation to relax the joints, muscles and ligaments connecting the pelvis and spine.

[0074] Or, such as Figure 7 As shown, firstly, the trainee fixes the traction rope 5 to a suitable position at the rear end of the movable rocker arm. Then, the roller mechanism 4 is adjusted to a suitable position for the user. Next, the traction rope 5 is looped around the roller 41 and passed through the opening 21 on the backrest 2. The user lies flat on the backrest 2, and the traction rope 5 is looped up from under the user's crotch and tied around the user's waist, secured, and adjusted to a comfortable tightness. Secondly, the traction operation is performed. The user raises both hands and grasps the upper front part of the rocker arm at a suitable position, slowly pulling downwards. The lever action causes the traction rope to move under the guidance of the rollers, generating traction force on the lower back. The user can control the amplitude and force of the pull according to their own tolerance. Through the action on the user's pelvis, traction training of the lumbar and sacral spine is achieved, improving the physiological curvature of the lumbar spine. Thirdly, traction adjustment: During the traction process, medical staff can adjust the direction of traction force in real time according to the user's feedback and treatment needs, or the user can adjust the height of the roller mechanism themselves. The user can also stop or adjust the pulling operation as needed based on their own feelings. Finally, to end the procedure, after the traction therapy is completed, the user releases the bar and unties the lumbar traction rope.

[0075] Step 4: Perform spinal stretching traction using the patented product CN201920087842.3 or CN201920087831.5. Two methods of use are provided:

[0076] Firstly, the user adjusts the number of weights according to the required intensity, puts straps on both feet, lies face down on a flat bed with their head facing one end of the stretching frame, and grips the support bar with both hands, pulling forward. The body moves towards the stretching frame, and the weights are lifted upwards by the straps and traction ropes. Conversely, if the user exerts no force, the weight will cause them to move backwards back to their starting position. This process is repeated to stretch the user's lumbar spine. The user can also choose the appropriate height of the support bar based on the degree of lumbar deformity to achieve the best fitness and rehabilitation effect. Alternatively, a head strap can be attached to the hanging hole of the support bar to pull the user's cervical spine.

[0077] Secondly, the user adjusts the number of weights according to the required intensity, puts straps on both feet, lies face down on the sliding support board with their head facing one end of the stretching frame, and holds the leverage bar with both hands, pulling forward. The sliding support board slides towards the stretching frame, lifting the weights upward through the straps and traction ropes. Conversely, if the user exerts no force, the sliding support board slides back into its original position under the weight of the weights. This process is repeated to stretch the user's lumbar spine. The user can also choose the appropriate height of the leverage bar based on the degree of lumbar spine deformation to achieve the best fitness and rehabilitation effect. The stretching and traction is generally performed 50 times, but the user can adjust the number of repetitions according to their own condition.

[0078] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent transformations or improvements made on the basis of the technical solution of the present utility model should be included within the protection scope of the present utility model.
