[0002] Sports can improve physical strength and reaction speed, as well as overall health, which is why many people participate in some form of sports.

[0003] Pull-ups are a standard exercise in physical training, primarily testing the development of upper limb muscle strength. They are a key indicator of upper limb strength in men, involving using one's own strength to overcome gravity during a hanging exercise. It is a fundamental method for strengthening the back and an important reference standard for assessing male physique. However, pull-up training is a gradual process. Many beginners or those with poor physical fitness find it difficult to overcome their own weight to complete pull-ups. Ordinary pull-up machines are often ineffective, reducing their practicality. Utility Model Content

[0004] To address the technical problem that many beginners or those with poor physical fitness find it difficult to overcome gravity and complete pull-ups during training, and that ordinary pull-up equipment cannot assist trainees in training, thus reducing the practicality of the equipment, this utility model provides a sports training device for physical education.

[0005] The technical solution adopted by this utility model is as follows: It includes two sets of uprights, each set having a crossbeam fixedly connected to it. Two sets of handles are fixedly installed on one side of each crossbeam, and anti-slip sleeves are fixedly connected to the outside of each set of handles. An auxiliary plate is slidably installed on one side of each set of uprights, and an auxiliary box is fixedly installed on the other side of each set of uprights. An adjusting plate is installed in the auxiliary box, and a spring is fixedly installed at the bottom of the adjusting plate. A sliding plate is fixedly connected to the lower end of the spring. Support rods are fixedly connected to both sides of each upright, and pulleys are rotatably installed on each support rod. A steel cable is slidably installed on the outside of each pulley, with one end of the steel cable fixedly connected to the auxiliary plate and the other end fixedly connected to the sliding plate.

[0006] Furthermore, four sets of limiting blocks are fixedly installed on the inner wall of the auxiliary box. The four sets of limiting blocks are evenly distributed around the inner wall of the auxiliary box. The limiting blocks are set between the adjusting plate and the sliding plate. An adjusting mechanism is provided in the auxiliary box.

[0007] By adopting the above technical solution, the distance the skateboard can move is limited.

[0008] Furthermore, the adjustment mechanism includes a mounting block fixedly installed on the top wall of the auxiliary box. The bottom of the mounting block has a mounting groove, and two sets of sliding seats are slidably connected in the mounting groove. A connecting rod is movably connected between the two sets of sliding seats and the adjustment plate.

[0009] The height of the adjustment plate can be adjusted by adopting the above technical solution.

[0010] Furthermore, a mounting base is fixedly connected to the slide block, one end of the connecting rod is rotatably mounted on the mounting base, and the other end of the connecting rod is rotatably mounted on a hinge seat, which is fixedly mounted on the adjusting plate.

[0011] By adopting the above technical solution, the connecting rod is movably installed between the slide and the adjusting plate.

[0012] Furthermore, a drive motor is fixedly installed on one side of the mounting block, and a bidirectional lead screw is coaxially fixedly connected to the drive shaft of the drive motor. The bidirectional lead screw is rotatably installed in the mounting groove, and the slide block is threadedly connected to the bidirectional lead screw. A control panel is fixedly installed on one side of the column.

[0013] By adopting the above technical solution, the drive motor drives the two sets of slides to move relative to each other.

[0014] Furthermore, a sliding groove is provided on the side wall of the mounting groove, and a slider is slidably connected in the sliding groove. The slider is fixedly installed on the side of the slide block.

[0015] By adopting the above technical solution, the stability of the slide during movement is improved.

[0016] Furthermore, a guide groove is provided on one side of the column, and a guide block is fixedly connected to one side of the auxiliary plate, with the guide block slidably connected in the guide groove.

[0017] By adopting the above technical solution, the stability of the auxiliary plate during the lifting and lowering process is improved.

[0018] The beneficial effects of this utility model are: by combining the column with the crossbeam, handle, auxiliary plate, support rod, pulley, steel cable, auxiliary box, adjustment plate, slide plate and spring, the elastic force of the spring is used to make the auxiliary plate apply an upward push to the trainee, which helps the trainee overcome part of his own weight, assists the trainee who is a beginner or has poor physical fitness to complete the pull-up training, and improves the practicality of the device. By using a mounting block in conjunction with a drive motor, a two-way lead screw, a slide block, a mounting base, a connecting rod, a hinge block, and an adjusting plate, the limiting block restricts the movement distance of the skateboard. The overall elastic force of the spring on the skateboard is adjusted to regulate the amount of thrust applied to the trainee by the auxiliary plate, making the device suitable for trainees of different physical abilities and further improving its practicality.

[0023] The following is in conjunction with the appendix Figure 1 -Appendix Figure 6 The present invention will be further described below.

[0024] To address the problems existing in the background technology, this application proposes the following technical solution: It includes a column 1, which is configured as two sets. A crossbeam 2 is fixedly connected to each set of columns 1. Two sets of handles 3 are fixedly installed on one side of the crossbeam 2. Anti-slip sleeves 4 are fixedly connected to the outside of each set of handles 3. An auxiliary plate 5 is slidably installed on one side of each set of columns 1. An auxiliary box 6 is fixedly installed on the other side of each set of columns 1. An adjusting plate 10 is installed in the auxiliary box 6. A spring 12 is fixedly installed at the bottom of the adjusting plate 10. A sliding plate 11 is fixedly connected to the lower end of the spring 12. Support rods 7 are fixedly connected to both sides of the column 1. A pulley 8 is rotatably installed on each support rod 7. A steel cable 9 is slidably installed on the outside of the pulley 8. One end of the steel cable 9 is fixedly connected to the auxiliary plate 5, and the other end of the steel cable 9 is fixedly connected to the sliding plate 11.

[0025] Beginners or those with poor physical fitness stand on the auxiliary board 5. The auxiliary board 5 moves downwards under gravity, pulling one end of the steel cable 9. Guided by the pulley 8, the other end of the steel cable 9 pulls the slide plate 11 upwards. The spring 12 between the slide plate 11 and the adjusting plate 10 is compressed and deformed. To return to its initial state, the compressed spring 12 pushes the slide plate 11 downwards. The elastic force of the spring 12 is applied to the auxiliary board 5 through the steel cable 9, creating an upward traction force. When the trainee grips the handles 3 to perform pull-ups, the upward traction force on the auxiliary board 5 helps the trainee overcome part of their own weight, reducing the effort required to complete the pull-up. This is suitable for beginners or those with poor physical fitness. For trainees with better physical fitness, bending their legs prevents their feet from contacting the auxiliary board 5, allowing them to overcome their own weight and complete the pull-up. The device caters to different fitness levels, improving its practicality.

[0026] Furthermore, four sets of limiting blocks 13 are fixedly installed on the inner wall of the auxiliary box 6. The four sets of limiting blocks 13 are evenly distributed around the inner wall of the auxiliary box 6. The limiting blocks 13 are located between the adjusting plate 10 and the sliding plate 11. An adjusting mechanism is provided in the auxiliary box 6.

[0027] Limiting block 13 restricts the movement distance of adjusting plate 10, and slide plate 11 can only move between the bottom of auxiliary box 6 and the base of limiting block 13, thus limiting the deformation of spring 12 of slide plate 11. Adjusting mechanism can make adjusting plate 10 move up and down. It should be noted that spring 12 installed between adjusting plate 10 and slide plate 11 is in a compressed state in the initial state. During the raising and lowering of adjusting plate 10, spring 12 is always in a compressed state and always applies a downward thrust to slide plate 11. When adjusting plate 10 moves upward, the distance between adjusting plate 10 and slide plate 11 increases, and the thrust on slide plate 11 decreases when slide plate 11 moves under limiting block 13. When adjusting plate 10 moves downward, the distance between adjusting plate 10 and slide plate 11 shortens, and the push on slide plate 11 increases when slide plate 11 moves under limiting block 13. Thus, the adjusting mechanism can adjust the amount of thrust applied by auxiliary plate 5 to trainee, making the device suitable for trainees with different physical abilities and further improving the practicality of the device.

[0028] Furthermore, the adjustment mechanism includes a mounting block 14 fixedly installed on the top wall inside the auxiliary box 6. The bottom of the mounting block 14 has a mounting groove 15, and two sets of sliding seats 16 are slidably connected in the mounting groove 15. A connecting rod 18 is movably connected between the two sets of sliding seats 16 and the adjustment plate 10.

[0029] The height of the adjustment plate 10 is adjusted by the relative movement between the two sets of slides 16. When the two sets of slides 16 are relatively close, the slides 16 push the adjustment plate 10 downward through the connecting rod 18, increasing the pushing force of the auxiliary plate 5 on the trainee. When the two sets of slides 16 are relatively far apart, the slides 16 pull the adjustment plate 10 upward through the connecting rod 18, reducing the pushing force of the auxiliary plate 5 on the trainee.

[0030] To further explain, a mounting base 17 is fixedly connected to the slide block 16, one end of the connecting rod 18 is rotatably mounted on the mounting base 17, and the other end of the connecting rod 18 is rotatably mounted on a hinge seat 19, which is fixedly mounted on the adjusting plate 10.

[0031] When the slide 16 moves, it drives the mounting base 17 to move. The mounting base 17 drives the connecting rod 18 to move. The connecting rod 18 pushes or pulls the hinge seat 19 to move. The hinge seat 19 drives the adjusting plate 10 to move up or down. Through the setting of the mounting base 17 and the hinge seat 19, the connecting rod 18 is movably installed between the slide 16 and the adjusting plate 10. The interior of the auxiliary box 6 and the adjusting plate 10 and the sliding plate 11 are all rectangular. The four sides of the adjusting plate 10 and the sliding plate 11 are in contact with the inner wall of the auxiliary box 6. The inner wall of the auxiliary box 6 plays a guiding and limiting role in the movement of the adjusting plate 10 and the sliding plate 11, so that the adjusting plate 10 and the sliding plate 11 will not flip during the movement, ensuring stable movement.

[0032] To further explain, a drive motor 20 is fixedly installed on one side of the mounting block 14, and a bidirectional lead screw 21 is coaxially fixedly connected to the drive shaft of the drive motor 20. The bidirectional lead screw 21 is rotatably installed in the mounting groove 15, and the slide block 16 is threadedly connected to the bidirectional lead screw 21. A control panel 24 is fixedly installed on one side of the column 1.

[0033] The control panel 24 is electrically connected to the drive motor 20. When the drive motor 20 is working, it drives the bidirectional lead screw 21 to rotate. The bidirectional lead screw 21 pushes the two sets of slides 16 to move relative to each other. The control panel 24 controls the start, stop, speed and direction of the drive motor 20, which makes it easy to adjust the auxiliary force of the auxiliary plate 5 on the trainee during training and improves the ease of use of the device. The drive motor 20 adopts Y2-100L1-4, but other models that meet the requirements can also be used.

[0034] Furthermore, a sliding groove 22 is provided on the side wall of the mounting groove 15, and a slider 23 is slidably connected in the sliding groove 22. The slider 23 is fixedly installed on the side of the slide block 16.

[0035] The slider 23, in conjunction with the slide groove 22, guides and limits the movement of the slide block 16, preventing the slide block 16 from flipping over when the bidirectional lead screw 21 rotates, thus improving the stability of the slide block 16 in the mounting groove 15 and thereby improving the stability of the adjusting plate 10 during the adjustment process.

[0036] To further explain, a guide groove 25 is provided on one side of the column 1, and a guide block 26 is fixedly connected to one side of the auxiliary plate 5. The guide block 26 is slidably connected in the guide groove 25.

[0037] The guide block 26, together with the guide groove 25, guides and limits the movement of the auxiliary plate 5, thereby improving the stability of the movement of the auxiliary plate 5 during the trainee's pull-up.

[0038] The drive motor 20 and control panel 24 of the sports training device for sports teaching in this utility model are both purchased from the market and are existing technologies. Skilled personnel in this industry only need to install and operate them according to the accompanying instruction manual, without requiring creative labor from those skilled in the art. The electrical connections between the electrical components and the controller programming all adopt conventional technologies. This utility model does not involve improvements to the circuit connections and control programs.

[0039] For specific operation, please refer to the following instructions: For trainees with good physical fitness, when performing pull-ups, grip the handles 3 with both hands, bend your legs so that your feet do not touch the auxiliary board 5, and overcome your own weight to complete the pull-up exercise; For beginners or those with poor physical fitness, stand on the auxiliary board 5. The auxiliary board 5 moves downwards under gravity, pulling one end of the steel cable 9. Guided by the pulley 8, the other end of the steel cable 9 pulls the slide plate 11 upwards. The spring 12 between the slide plate 11 and the adjusting plate 10 is compressed and deformed. The elastic force of the spring 12 is applied to the auxiliary board 5 through the steel cable 9, exerting an upward force on the auxiliary board 5. The traction force of the auxiliary plate 5 helps the trainee overcome part of their own weight when they grip the handle 3 to do pull-ups, reducing the force required to complete the pull-up and assisting the trainee in completing the pull-up training. The drive motor 20 is controlled by the control panel 24. When the drive motor 20 is working, it drives the bidirectional lead screw 21 to rotate. The bidirectional lead screw 21 pushes the two sets of slides 16 to move relative to each other. The slides 16 pull or push the adjustment plate 10 to move up and down through the connecting rod 18, reducing or increasing the pushing force of the auxiliary plate 5 on the trainee, and assisting trainees with different physical abilities to complete the pull-up training.
