[0027] The present invention will now be described in detail and specifically through specific embodiments to enable a better understanding of the invention. However, the following embodiments do not limit the scope of protection of the present invention. Example
[0028] This embodiment discloses a lumbar spine rehabilitation training device.
[0029] like Figures 1 to 4 As shown, this embodiment includes a training device body 1, which consists of a lifting frame module 2, two fixed frame modules 3, and matching balance and limiting components. It achieves targeted waist training through mechanical transmission and sliding adaptation. The specific structure is as follows: (I) Core Training Structure: Lifting Frame Module 2 The lifting frame module 2 is located in the middle of the main body 1 of the trainer and is the core of the waist lifting training. It includes an arched plate 21, a lifting component 22, a support base 26, and a limiting frame 27, which work together to achieve stable vertical lifting movement. Arched plate 21: The arched plate 21 has an arc-shaped structure that conforms to the curve of the human waist. When the user lies flat, the waist is in close contact with the arched plate 21, ensuring even force transmission during training. Support rods 23 are provided at the bottom of both sides of the arched plate 21, and support columns 24 are provided on both sides. Support beams 25 are provided at the top of the two support columns 24. The support columns 24 are welded and fixed to the support beams 25 and support rods 23 to form a stable frame structure and prevent deformation during lifting and lowering.
[0030] Lifting assembly 22 includes a boom 221, a motor 222, and a connecting rope 223. The boom 221 and the motor 222 are fixed to one side of the arch plate 21 (the boom 221 can also be fixed to both sides of the arch plate 21 to increase the sense of security when lifting up and down). The rotating shaft of the motor 222 is equipped with a rope take-up wheel 224. The boom 221 is equipped with several cable pulleys 225. The connecting rope 223 (steel wire) passes around the cable pulley 225, with one end fixed to the middle of the support beam 25 and the other end wrapped around the rope take-up wheel 224. During operation, the motor 222 starts and drives the rope winding wheel 224 to rotate, winding or releasing the connecting rope 223. The direction of force is changed through the sling pulley 225, pulling the arched plate 21 vertically up and down. When the connecting rope 223 is wound up, the arched plate 21 rises and lifts the waist, achieving waist extension training; when the connecting rope 223 is released, the arched plate 21 descends, and the waist returns to a natural state. The lifting amplitude and speed can be precisely controlled to adapt to different training needs. The motor 222 is controlled by a remote control. A power strip and a box for the remote control can be installed next to the fixed frame. The power strip supplies power to the motor 222.
[0031] Support and limiting structure: A support seat 26 is provided below the support rod 23. The support seat 26 is welded and fixed to the connecting frame 5 to support the arch plate 21 in the normal state (when not training) and ensure the initial position is stable. Limiting frames 27 are provided on both sides of the support column 24. The limiting frames 27 are welded and fixed to the connecting frame 5 and are symmetrically distributed. They can limit the left and right displacement of the arch plate 21 and ensure that it always rises and falls in the vertical direction, thereby improving the stability and safety of training.
[0032] (ii) Adaptive sliding structure: Fixed frame module 3 Two fixed frame modules 3 are located at the front and rear ends of the lifting frame module 2, respectively, to support the back and legs of the human body. They are designed to slide to accommodate body movement and prevent clothing from being worn. The modules include a fixed plate 31, a movable plate 32, and a sliding assembly. Fixed plate 31 and movable plate 32: Fixed plate 31 is a horizontal support plate with slide rails 34 on both sides of the top; movable plate 32 is positioned above fixed plate 31 to directly support the human body, and has pulley groups 33 fixed on both sides of its bottom, which are slidably connected to the slide rails 34. This sliding design allows the movable plate 32 to slide synchronously with the user's body as they move back and forth during training, completely solving the problem of friction and wear between clothing and the plate, and improving user comfort.
[0033] Sliding assembly and fixing structure: The pulley assembly 33 includes a fixed base 331. A connecting rod 332 is located at the bottom of the fixed base 331. Sliding wheels 333 are rotatably mounted at both ends of the bottom of the connecting rod 332. The sliding wheels 333 are adapted to the slide rail 34 to ensure smooth and unobstructed sliding of the moving plate 32. The fixed plate 31 has supporting legs 35 at its bottom and two fixed legs 36 on both sides. Pressure strips 37 are located on the top of the two fixed legs 36 on the same side. The bottom surface of the pressure strips 37 is located on the top surface of the moving plate 32, and there is a gap between the bottom surface of the pressure strips 37 and the top surface of the moving plate 32 to prevent wobbling during training. A handle can be placed on the moving plate 32 for easy removal, allowing the moving plate to slide out of the fixed plate 31. A stop strip is placed on the fixed plate below the moving plate 32 to prevent the sliding wheels 333 under the moving plate 32 from sliding out of the fixed plate 31.
[0034] (III) Balancing and Moving Structure: Base Plate 4, Connecting Frame 5, and Counterweight Assembly 6 Base plate 4 and connecting frame 5: The bottom of the lifting frame module 2 and the fixed frame module 3 are provided with base plate 4, and the bottom of the two are provided with connecting frame 5 and welded and fixed to form an overall stable structure, which improves the overall load-bearing capacity of the trainer and prevents it from tipping over during training.
[0035] Counterweight Component 6: A counterweight component 6 is located on one side of the main body 1 of the trainer, on a different side from the lifting component 22. Its core function is to maintain the balance of the device. The counterweight component 6 includes two extension rods 61, which are welded and fixed to the connecting frame 5. Weights 64 (such as counterweight blocks) can be placed on the extension rods 61. The weight of the weights 64 balances the weight on one side of the lifting component 22, ensuring the overall stability of the trainer. A crossbar 62 is provided at the end of the extension rods 61, and a caster wheel 63 is provided at the bottom of the crossbar 62 to facilitate the movement of the entire trainer and improve ease of use. To maintain the balance on both sides, an extension frame can also be added to the side where the motor 222 is located.
[0036] I. Equipment Installation and Commissioning Placement and Fixation: Place the trainer on a flat ground and adjust its position using the moving wheel 63 at the end of the extension rod 61 to ensure that the base plate 4 is in close contact with the ground and that the support leg 35 and the fixed leg 36 are firmly on the ground without shaking; place an appropriate weight 64 on the extension rod 61 to balance the weight on one side of the lifting assembly 22 and ensure overall stability.
[0037] Component inspection: Check the fit between the arch plate 21 and the support base 26 to ensure stable support when not in operation; test whether the sliding plate 32 slides smoothly and whether the pulley block 33 and the slide rail 34 are stuck; check whether the connecting rope 223 (steel wire) is firmly wound on the rope take-up wheel 224 and whether the sling pulley 225 rotates flexibly; confirm that the gap between the limit frame 27 and the arch plate 21 is uniform and there is no one-sided friction.
[0038] Functional debugging: Start motor 222 and test whether the arch plate 21 rises and falls smoothly and vertically without lateral deviation; adjust the speed of motor 222 to confirm that the lifting speed is controllable; repeat the lifting and lowering process 3-5 times to check whether each welded part and connection part is firm and without looseness or abnormal noise.
[0039] II. Operation Procedure Training preparation: The user lies flat on the trainer, with the back and legs supported on the front and rear movable plates 32 respectively, and the waist aligned with the central arched plate 21. Adjust the body posture to a comfortable and close fit.
[0040] Training mode selection: Rehabilitation training (such as adjunctive treatment for lumbar disc herniation): Start the motor 222 to control the arched plate 21 to slowly rise and fall, which can be combined with manual assistance to adjust the lumbar posture.
[0041] Fitness and fat loss training: Increasing the frequency of lifting and lowering can effectively exercise waist muscles and burn abdominal fat.
[0042] Training process: When training, move your body back and forth, and the moving plate 32 slides synchronously with the slide rail 34 to avoid wear and tear on clothing; if you feel that the arched plate 21 is off-center, turn off the motor 222 in time to adjust it and ensure training safety.
[0043] End of operation: After training is completed, control the arch plate 21 to descend onto the support seat 26 and turn off the motor 222.
[0044] III. Maintenance and Care Daily cleaning: After use, wipe the contact parts such as the arched plate 21, the movable plate 32, and the fixed plate 31 with a damp cloth to remove dust and sweat; regularly clean the slide rail 34 and the pulley group 33 to remove debris and ensure smooth sliding.
[0045] Component inspection: Check the connecting rope 223 (steel wire) weekly for wear and broken wires, and replace it in time if there is any damage; check the welded parts (support column 24, connecting frame 5, limit frame 27, extension rod 61) for firmness, and reinforce them in time if they are loose; check the connection between the motor 222 and the rope take-up wheel 224 to ensure normal transmission.
[0046] Lubrication and maintenance: Apply a small amount of lubricating oil to the sliding wheel 333 of the slide rail 34 and the pulley block 33 every month to reduce friction and wear; avoid getting lubricating oil on clothing or other contact areas, and wipe it clean with a cloth if necessary.
[0047] Storage: When not in use for a long period of time, remove the weight 64 from the extension rod 61, move the trainer to a dry and ventilated place, and cover it with a dustproof cloth; regularly check whether the metal parts are rusted, and apply anti-rust oil if necessary.
