Description

Technical Field

[0001] This invention relates to the field of high jump and long jump training technology, and in particular to a comprehensive high jump and long jump training device. Background Technology

[0002] In the existing technology, long jump and high jump are two sports in sports. High jump is mainly divided into pole vault and running take-off, while long jump is mainly divided into running long jump and springboard long jump. Since the methods of high jump and long jump are different, high jump is often practiced with hurdles, while long jump is practiced with sandpits. Both have limited requirements for the venue and are inconvenient to use. Therefore, in order to facilitate the practice of height adjustment and long jump, it is necessary to design a comprehensive device that can adjust the height and long jump. When high jump or long jump is needed, the device can switch between the two states, so that it is not limited by the specific venue conditions.

[0003] A search revealed Chinese patent application number 201810879873.2, which discloses a comprehensive training device for high jump and long jump in sports training. The device includes a soft-padded frame, a telescopic rod A, a telescopic measuring rod, a sliding groove, a springboard base, and a springboard. The telescopic measuring rod is movably mounted on the top center of the fixed platform via a rotating shaft installed in a structure with rotating shaft seats on both sides. Multiple sets of through holes are formed on both sides of the connecting plate, and the through holes are parallel and evenly spaced. A springboard platform is integrally formed on one side of the top of the springboard base. The springboard base and the springboard are fixed in a square hole in the springboard platform by bolts passing through the springboard and springboard base and inserted into screw holes. The position of the springboard is fixed by the springboard base.

[0004] The high jump and long jump comprehensive training device for sports training mentioned in the above patent has the following shortcomings: During use, although the soft mat can be used to adjust the height, the long length of the soft mat makes it difficult to store, which is inconvenient when the device needs to be moved. Summary of the Invention

[0005] The purpose of this invention is to address the shortcomings of existing technologies by proposing a comprehensive training device for high jump and long jump.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A high jump and long jump comprehensive training device includes a protective component for high jump. The protective component includes a storage base one and a storage base two. An extension plate is welded to the inner wall of one side of the storage base one, and a rotating column is movably connected between the two extension plates. A winding cloth is adhered to the outer wall of the rotating column, and an airbag and a pad are respectively fixed to the bottom of the winding cloth by adhesive. A valve is adhered to one side of the airbag. A vertical plate is welded to the inner wall of the bottom of the storage base two, and a winding column is movably connected between the two vertical plates.

A fixing shell is fixed to the outer wall of one side of the vertical plate by screws, and the same coil spring is engaged between the inner wall of the fixing shell and the outer circumference of the winding column.

[0008] Preferably, a ratchet is fixed to one side of the outer wall of the extension plate, and a rotating rod is movably connected to one side of the outer wall of the extension plate. A support plate is welded to one end of the rotating rod. A T-shaped rod is movably connected to a through hole on the surface of one of the support plates. A ratchet tooth that works with the ratchet is fixed to the bottom of the T-shaped rod by a pin. A height adjustment mechanism is fixed to the top of both support plates.

[0009] Furthermore: a spring is sleeved on the outer circumference of the T-shaped rod, and the two ends of the spring are respectively engaged with the inner wall of one side of the T-shaped rod and the outer wall of the top of the support plate.

[0010] Furthermore: the height adjustment mechanism includes a multi-stage telescopic rod and a placement plate. The multi-stage telescopic rod is fixed to the top outer wall of the support plate, and the placement plate is fixed to the top of the multi-stage telescopic rod by screws. A marking plate is placed on the top of the two placement plates.

Detailed Implementation

[0031] The technical solution of this patent will be further described in detail below with reference to specific embodiments.

[0032] The embodiments of this patent are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this patent, and should not be construed as limiting this patent.

[0033] Example 1:

[0034] A comprehensive training device for high jump and long jump, such as Figures 1 to 8 As shown, a protective assembly for high jump is included. The protective assembly includes a storage base 1 and a storage base 2 5. An extension plate 10 is welded to the inner wall of one side of the storage base 1, and a rotating column 16 is rotatably connected between the two extension plates 10. A winding cloth 6 is glued to the outer wall of the rotating column 16, and an airbag 13 and a pad 4 are respectively fixed to the bottom of the winding cloth 6 by adhesive. A valve 12 is glued to one side of the airbag 13. A vertical plate 15 is welded to the inner wall of the bottom of the storage base 2 5, and a winding column 14 is rotatably connected between the two vertical plates 15. The end of the winding cloth 6 away from the rotating column 16 is wound around the outer circumference of the winding column 14. A fixing shell 24 is fixed to the outer wall of one side of the vertical plate 15 by screws, and the same coil spring 23 is engaged between the inner wall of the fixing shell 24 and the outer circumference of the winding column 14.

[0035] When a high jump is required, the storage base 2 5 is pulled along the storage base 1 1. During the movement of the storage base 2 5, the winding cloth 6 wrapped around the outer circumference of the winding column 14 is unwound laterally. After connecting the manual air cylinder or air pump to the valve 12, air is injected into the airbag 13 through the valve 12. The airbag 13 expands after inflation, and the expanded airbag 13 protects the trainee after the high jump to prevent accidents. After the high jump training is completed, the storage base 2 5 is lifted, and the rebound force of the coil spring 23 causes the winding cloth 6 to be rewound around the outer circumference of the winding column 14. The winding column 14 is used to wind the winding cloth 6 and the deflated airbag 13, thereby reducing the footprint of the entire device and improving its portability.

[0036] When long jump training is required, the airbag 13 is in the deflated state, and the pad 4 supports the ground. The cavity formed between the pad 4 and the rolled cloth 6 can contain the deflated airbag 13. The pad 4 increases the friction between the rolled cloth 6 and the ground, preventing the rolled cloth 6 from slipping relative to the ground. When long jumping, the trainee stands on the storage seat 1 and jumps onto the rolled cloth 6. The rolled cloth 6 can increase the friction of the shoes, preventing the trainee from slipping.

[0037] Furthermore, a ratchet 17 is fixed to one side of the outer wall of the extension plate 10 by bolts, and a rotating rod 18 is rotatably connected to one side of the outer wall of the extension plate 10. A support plate 21 is welded to one end of the rotating rod 18. A T-shaped rod 20 is slidably connected to a through hole on the surface of one of the support plates 21. A ratchet tooth 28 that works with the ratchet 17 is fixed to the bottom of the T-shaped rod 20 by a pin. A spring 22 is sleeved on the outer circumference of the T-shaped rod 20. The two ends of the spring 22 are respectively snapped into the inner wall of one side of the T-shaped rod 20 and the top outer wall of the support plate 21. A height adjustment mechanism is fixed to the top of the two support plates 21.

[0038] When trainees need to perform high jump training, the rotating rod 18 is rotated along the outer wall of one side of the extension plate 10. Taking advantage of the characteristic that the ratchet 28 can only rotate in one direction along the outer wall of the ratchet 17, the rotating rod 18 stops rotating when the support plate 21 is rotated to be parallel to the horizontal plane. At this time, the height adjustment mechanism rotates to be perpendicular to the horizontal plane. The height adjustment mechanism is used to adjust the height of the high jump. When the trainee jumps, he / she takes off from the side of the receiving seat 1. Since the ratchet 28 cannot rotate in the opposite direction along the ratchet 17, the height adjustment mechanism is prevented from shaking after the trainee takes off and comes into contact with him / her, thus ensuring the stability of the height adjustment mechanism during the high jump.

[0039] Furthermore, the height adjustment mechanism includes a multi-stage telescopic rod 7 and a placement plate 19. The multi-stage telescopic rod 7 is fixed to the top outer wall of the support plate 21 by bolts, and the placement plate 19 is fixed to the top of the multi-stage telescopic rod 7 by screws. A marking plate 11 is placed on the top of the two placement plates 19.

[0040] The multi-stage telescopic bar 7 can extend and retract in multiple stages. When the marking board 11 is placed on top of the placement board 19, high jump training is conducted. The multi-stage telescopic units of the multi-stage telescopic bar 7 have strong damping, which can effectively prevent movement between the multi-stage telescopic units of the multi-stage telescopic bar 7 during the high jump.

[0041] Furthermore, the bottom outer wall of the storage base 1 is fixed with a bracket 3 by bolts, and the bottom of the bracket 3 is rotatably connected with a self-locking universal wheel 2;

[0042] The self-locking casters 2 facilitate the movement of the storage seat 1, thereby expanding the training area.

[0043] Furthermore, the bottom outer wall of the storage base 25 is fixed with a bracket 29 by bolts, and the bottom of the bracket 29 is rotatably connected with a self-locking universal wheel 28;

[0044] The self-locking caster 28 is used in conjunction with the self-locking caster 12 to facilitate the movement of the two as a whole after they are closed together between the storage base 1 and the storage base 25. Both the self-locking caster 12 and the self-locking caster 28 can be self-locked, thus ensuring stability during high jump or long jump.

[0045] In this embodiment, the storage seat 2 5 is first pulled along the storage seat 1, so that the rolled cloth 6 unfolds during the movement of the storage seat 2 5. When the storage seat 2 5 moves to the set position, the self-locking caster 2 8 and the self-locking caster 1 2 are locked. When high jump training is required, the valve 12 is used to inflate the airbag 13. When the airbag 13 expands to a certain extent, the rotating rod 18 is rotated along the extension plate 10. During the rotation of the rotating rod 18, the ratchet 28 rotates unidirectionally along the ratchet 17. When the multi-stage telescopic rod 7 is rotated to be perpendicular to the horizontal plane, the height of the multi-stage telescopic rod 7 is adjusted according to the high jump height. Then, the marking plate 11 is placed on the placement plate 19 and high jump training is carried out.

[0046] When long jump training is required, valve 12 is opened to deflate airbag 13. After airbag 13 is deflated, pad 4 is supported on the ground. Then, T-bar 20 is pulled. When ratchet 28 disengages from ratchet 17, multi-stage telescopic rod 7 is rotated in the opposite direction. When multi-stage telescopic rod 7 is rotated to the lateral position, the length of the long jump can be monitored using multi-stage telescopic rod 7. Self-locking caster 2 8 is used in conjunction with self-locking caster 1 2 to facilitate the movement of the two as a whole after they are closed between storage seat 1 1 and storage seat 2 5. Both self-locking caster 1 2 and self-locking caster 2 8 can be self-locked to ensure stability during high jump or long jump.

[0047] Example 2:

[0048] A comprehensive training device for high jump and long jump, such as Figures 1 to 8 As shown, in order to ensure the stability of the storage base 1 and the storage base 2 5 after they are closed, this embodiment makes the following improvements based on embodiment 1: The top outer wall of the storage base 1 is fixed with a receiving plate 30 by bolts, and a sliding rod 25 is slidably connected to the through hole on the surface of the receiving plate 30. One end of the sliding rod 25 is fixed with a locking plate 29 by a pin. A spring 26 is sleeved on the outer wall of the sliding rod 25, and the two ends of the spring 26 are respectively locked to the inner wall of one side of the sliding rod 25 and the outer wall of one side of the receiving plate 30. The top outer wall of the storage base 2 5 is fixed with a conical locking plate 27 that works in conjunction with the two sets of locking plates 29 by bolts.

[0049] When the storage base 1 and the storage base 2 5 are closed to store the rolled fabric 6, the conical clamping plate 27 moves into the notch formed between the two clamping plates 29. The notch can limit the conical clamping plate 27, thereby ensuring the relative stability between the storage base 1 and the storage base 2 5 and preventing the storage base 1 and the storage base 2 5 from separating from each other during the movement.

[0050] The above description represents a preferred embodiment of the present invention. The scope of protection of the present invention is not limited thereto. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the scope of the technology disclosed in the present invention, combined with existing technology or common knowledge, and within the spirit and principles of the present invention, should be covered within the scope of protection of the present invention.
