Description

Technical Field

[0001] This utility model relates to the field of sports teaching technology, specifically to a multifunctional stretching equipment for sports teaching. Background Technology

[0002] Physical education encompasses a wide range of activities, including track and field, ball games, gymnastics, martial arts, and swimming. It also covers theoretical topics such as exercise physiology, sports safety, and health knowledge. Its core objective is to enable students to master scientific exercise methods and develop healthy lifestyle habits through systematic learning and practice. Stretching is a crucial component of physical education; whether it's pre-class warm-up, in-class cool-down, or specific training, scientific stretching is indispensable. Using stretching equipment can make stretching more efficient and safer.

[0003] Currently used stretching equipment in physical education often suffers from insufficient adaptability. Due to the significant height differences among students of different ages and developmental stages, the fixed height design of existing stretching equipment forces shorter students to overstretch their limbs when using taller equipment, which can easily lead to joint injuries. On the other hand, taller students cannot fully extend their bodies when using shorter equipment, resulting in a significant reduction in the stretching effect. Utility Model Content

[0004] To achieve the above objectives, this utility model provides the following technical solution:

[0005] A multifunctional stretching equipment for physical education includes:

[0006] The base has a second sleeve connected to its upper part. A lifting plate is slidably connected inside the second sleeve. A triangular block is connected to the inner side of the lifting plate. A toothed groove is opened on the back side of the lifting plate. A first through hole is opened on the back side of the second sleeve. A driving mechanism is provided on the back side of the second sleeve near the first through hole.

[0007] The front end of the lifting plate is connected to a first sleeve, and telescopic rods are slidably connected to both sides of the first sleeve. Eight slots are equidistantly opened on the front side of the telescopic rods. A pulley is connected to the bottom of the telescopic rods, and a nylon rope is slidably connected to the outer side of a pair of pulleys. A pair of second through holes are correspondingly opened on the front side of the first sleeve, and a positioning mechanism is provided on the front side of the first sleeve near the second through holes.

[0008] In one possible implementation, the drive mechanism includes a pair of bearing seats, with a shaft rotatably connected inside the pair of bearing seats. One end of the shaft is connected to a gear that meshes with a toothed tooth, and the other end of the shaft is connected to a knob.

[0009] In one possible implementation, a ratchet is connected to the outer side of the shaft and the inner side of the bearing seat and the knob. A positioning shaft is connected to the outer side of the bearing seat on the left side. A ratchet is rotatably connected to the outer side of the positioning shaft. One end of the ratchet is engaged with the ratchet. A first spring is connected to the back side of the ratchet. One end of the first spring is connected to a side plate. One side of the side plate is fixedly connected to the bearing seat.

[0010] In one possible implementation, a pressure plate is connected to the other side of the shaft.

[0011] In one possible implementation, the positioning mechanism includes a U-shaped plate with a third through hole inside. A rod is slidably connected inside the third through hole. One end of the rod extends into the inside of a slot, and the other end of the rod is connected to a pull plate. A ring is fixedly connected to the outside of the rod and to the front of the first sleeve. A second spring is sleeved on the outside of the rod. One end of the second spring is fixedly connected to the ring, and the other end of the second spring is fixedly connected to the U-shaped plate.

[0012] In one possible implementation, slide rails are connected to both the upper and lower side walls of the first sleeve, and a slider is slidably connected inside the slide rails, with one side of the slider being fixedly connected to the telescopic rod.

[0013] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0014] Rotating the knob counterclockwise facilitates the rotation of the gears, which in turn raises the toothed groove and lifting plate, allowing for easy adjustment of the nylon rope height. Simultaneously, it rotates the ratchet counterclockwise, and the engagement between the ratchet and its teeth helps prevent the gears from rotating in the opposite direction, thus stabilizing the lifting plate height. Pulling the pull plate outwards allows for easy removal of the insertion rod from one side of the telescopic rod, facilitating adjustment of the distance between the two telescopic rods. This allows the equipment to be adapted to different students' heights and body proportions, further enhancing its flexibility. Attached Figure Description

[0023] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0024] This application provides a multifunctional stretching device for physical education, thereby solving the problems in the prior art.

[0025] The technical solution in this application is to solve the above problems, and the overall approach is as follows:

[0026] like Figures 1-5 As shown, a multifunctional stretching equipment for physical education includes:

[0027] The base 7 has a second sleeve 6 connected above it. The second sleeve 6 has a lifting plate 2 slidably connected inside it. The inner side of the lifting plate 2 is connected to a triangular block 1. The back side of the lifting plate 2 has a toothed groove 12. The back side of the second sleeve 6 has a first through hole 10. The back side of the second sleeve 6 is provided with a drive mechanism near the first through hole 10.

[0028] The front end of the lifting plate 2 is connected to the first sleeve 3. The two sides of the first sleeve 3 are slidably connected to the telescopic rods 4. The front side of the telescopic rods 4 is provided with eight slots 15 at equal intervals. The bottom of the telescopic rods 4 is connected to the pulleys 5. The outer side of a pair of pulleys 5 is slidably connected to the nylon ropes 8. The front side of the first sleeve 3 is provided with a pair of second through holes 17. The front side of the first sleeve 3 is provided with a positioning mechanism near the second through holes 17.

[0029] In some examples, the drive mechanism includes a pair of bearing seats 20, with a shaft 26 rotatably connected inside the pair of bearing seats 20. One end of the shaft 26 is connected to a gear 14, which meshes with a toothed groove 12. The other end of the shaft 26 is connected to a knob 13. Rotating the knob 13 counterclockwise facilitates the rotation of the gear 14, which in turn facilitates the lifting of the toothed groove 12 and the lifting plate 2, thereby facilitating the adjustment of the height of the nylon rope 8.

[0030] In some examples, a ratchet 19 is connected to the outer side of the shaft 26 and the inner side of the bearing seat 20 and the knob 13. A positioning shaft 23 is connected to the outer side of the left bearing seat 20. A ratchet 25 is rotatably connected to the outer side of the positioning shaft 23. One end of the ratchet 25 is engaged with the ratchet 19. A first spring 24 is connected to the back side of the ratchet 25. One end of the first spring 24 is connected to a side plate 21. One side of the side plate 21 is fixedly connected to the bearing seat 20. When the shaft 26 rotates, it drives the ratchet 19 to rotate counterclockwise in sync. The cooperation between the ratchet 19 and the ratchet 25 helps to prevent the gear 14 from rotating in the opposite direction, thus stabilizing the height of the lifting plate 2.

[0031] In some examples, a pressure plate 22 is connected to the other side of the shaft 26. When the knob 13 needs to be rotated clockwise, the pressure plate 22 can be pressed down to separate one end of the drive ratchet 25 from the ratchet 19, making it convenient to rotate the knob 13.

[0032] In some examples, the positioning mechanism includes a U-shaped plate 18 with a third through hole 27 inside. A rod 28 is slidably connected inside the third through hole 27. One end of the rod 28 extends into the slot 15, and the other end of the rod 28 is connected to a pull plate 9. A ring 29 is fixedly connected to the outside of the rod 28 and to the front of the first sleeve 3. A second spring 30 is sleeved on the outside of the rod 28. One end of the second spring 30 is fixedly connected to the ring 29, and the other end of the second spring 30 is fixedly connected to the U-shaped plate 18. Pulling the pull plate 9 outward and simultaneously squeezing the second spring 30 facilitates the removal of the rod 28 from one side of the telescopic rod 4, thereby facilitating the adjustment of the distance between the two telescopic rods 4. Then, the pull plate 9 is released, and the elastic force of the second spring 30 drives the rod 28 to be inserted into the telescopic rod 4, completing the fixation.

[0033] In some examples, the upper and lower side walls of the first sleeve 3 are connected to slide rails 11, and sliders 16 are slidably connected inside the slide rails 11. One side of the sliders 16 is fixedly connected to the telescopic rods 4. The cooperation between the slide rails 11 and the sliders 16 helps to improve the stability of the telescopic rods 4 on both sides.

[0034] This invention allows for easy rotation of the gear 14 by rotating the knob 13 counterclockwise, which in turn facilitates the lifting of the toothed groove 12 and the lifting plate 2, thereby enabling easy adjustment of the height of the nylon rope 8. Simultaneously, it drives the ratchet 19 to rotate counterclockwise. The cooperation between the ratchet 19 and the ratchet tooth 25 helps prevent the gear 14 from rotating in the opposite direction, thus stabilizing the height of the lifting plate 2. At the same time, pulling the pull plate 9 outwards makes it easy to remove the insertion rod 28 from one side of the telescopic rod 4, and then easily adjust the distance between the two telescopic rods 4. This allows the equipment to be adapted to different students' heights and body proportions, further improving the flexibility of adaptation.

[0035] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
