Description

Technical Field

[0001] This utility model relates to the field of sports training equipment technology, specifically a barbell rack structure for track and field training with shock absorption and cushioning function. Background Technology

[0002] Track and field training is a comprehensive and systematic process that requires the integration of strength, speed, endurance, technique, and psychological training. Through scientific and reasonable training plans and professional technical guidance, athletes can achieve better results in competitions while reducing the risk of injury. Using barbells is a very important training method for athletes. It can not only enhance strength, explosiveness, and endurance, but also improve core stability, prevent injuries, and enhance coordination. Barbells are used in conjunction with barbell racks.

[0003] Currently available barbell racks only provide simple support and protection for the barbell, aiming to prevent it from falling and hitting the athlete's chest or neck when they are exhausted. However, when the barbell falls and comes into contact with the protective frame on the barbell rack, it will be subjected to a reaction force and its own weight, causing it to bounce up and down between the two protective frames. During this bouncing process, the position of the barbell will shift, and there is still a possibility that the barbell could hit the athlete. Utility Model Content

[0004] The purpose of this invention is to provide a barbell rack structure for track and field training with shock absorption and cushioning function, so as to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: A barbell rack structure for track and field training with shock absorption and cushioning function includes a support frame and a reclining frame. Two hooks are fixedly connected to the top side of the support frame. Two symmetrical shock absorption and cushioning mechanisms for damping and cushioning the barbell are provided on the side of the support frame. The shock absorption and cushioning mechanism includes a cushioning component that slides on the side of the support frame. A limiting component for limiting the barbell is provided on the bottom surface of the cushioning component. The buffer assembly includes a movable plate that slides on the side of the support frame, and a storage shell is fixedly connected to the bottom surface of the movable plate. The limiting component includes two symmetrical arc-shaped guide plates fixedly connected between the two ends of the movable plates at corresponding positions. Each end of the arc-shaped guide plate has a slide rail. A compression member is provided between the two arc-shaped guide plates at opposite positions. The compression member is located inside the storage shell at the corresponding position. A limiting plate is slidably connected inside the slide rail.

[0006] Furthermore, the compression component includes an airbag disposed inside a storage shell at a corresponding position. The airbag is fixedly connected to a connecting pipe that penetrates the storage shell at the corresponding position. A three-way pipe is fixedly connected to the bottom end of the connecting pipe. Both ends of the three-way pipe are fixedly connected to air pipes that are fixedly connected to an arc-shaped guide plate at the corresponding position.

[0007] Furthermore, the arc-shaped guide plate has a T-shaped air hole in its center.

[0008] Furthermore, the arc of the arc-shaped guide plate is greater than 180 degrees, and a sealing gasket is provided on the outer side of the limiting plate.

[0009] Furthermore, the storage shell has a pressure plate slidably fitted inside, and the top surface of the pressure plate is fixedly connected to a telescopic plate that slides through a moving plate at a corresponding position. The top surface of the telescopic plate has an arc-shaped groove, and a buffer pad is fixedly connected inside the arc-shaped groove.

[0010] Furthermore, the support frame has two symmetrical sliding holes through its side. A sliding rod is fixedly connected between the two ends of the sliding hole. A slider is slidably connected to a moving plate at a corresponding position through the outer wall of the sliding rod. A spring is fixedly connected between the slider and the sliding hole at the corresponding position.

[0011] Furthermore, connecting blocks are fixedly connected to the top of both sides of the telescopic plate, and springs are fixedly connected between the connecting blocks and the corresponding movable plates.

[0012] Compared with the prior art, the beneficial effects of this utility model are: The pressure applied to the compression components as the barbell falls causes them to compress and force the gas inside into the two arc-shaped guide plates at corresponding positions. This causes two limiting plates inside the arc-shaped guide plates to extend, thereby securing the end of the barbell and preventing it from shifting position and hitting the athlete when subjected to the opposing forces of the two cushioning components.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0016] Please see Figure 1 - Figure 6 In this embodiment of the present invention, a barbell rack structure for track and field training with shock absorption and cushioning function includes a support frame 1 and a reclining frame 2. Two hooks 11 are fixedly connected to the top side of the support frame 1. The reclining frame 2 is fixedly connected inside the support frame 1. Two symmetrical shock absorption and cushioning mechanisms 3 are provided on the side of the support frame 1 for damping and cushioning the barbell. Each shock absorption and cushioning mechanism 3 includes a cushioning component 31 that slides on the side of the support frame 1. A limiting component 32 for limiting the barbell's position is provided on the bottom surface of the cushioning component 31. Component 31 includes a movable plate 311 that slides on the side of the support frame 1. A storage shell 312 is fixedly connected to the bottom surface of the movable plate 311. The limiting component 32 includes two symmetrical arc-shaped guide plates 321 that are fixedly connected between the two ends of the movable plate 311 at corresponding positions. Slide rails 322 are provided at both ends of the arc-shaped guide plates 321. A compression member is provided between the two arc-shaped guide plates 321 at opposite positions. The compression member is located inside the storage shell 312 at the corresponding position. A limiting plate 323 is slidably connected inside the slide rails 322.

[0017] Specifically, during the exercise, the athlete lies on the bench 2 and uses a barbell for training. The athlete's hands move the barbell up and down. When the athlete moves the barbell downwards, it contacts the two cushioning components 31 and causes the two shock-absorbing mechanisms 3 to move downwards (because the athlete's arms exert an upward supporting force on the barbell, the force exerted by the barbell on the two shock-absorbing mechanisms 3 is relatively small). However, when the athlete reaches exhaustion during training, the barbell falls from a height. During its fall, the barbell contacts the two cushioning components 31. Due to the athlete's exhaustion, the arms no longer exert an upward supporting force on the barbell, so the barbell falls quickly, exerting a very large force on the two cushioning components 31. This compresses the compressor inside the housing 312 and forces the gas inside into the two arc-shaped guide plates 321 at corresponding positions. This causes the two limiting plates 323 inside the arc-shaped guide plates 321 to be pushed out and move in a circular motion along the center of the arc-shaped guide plates 321. Until the tops of the two limiting plates 323 within the same arc-shaped guide plate 321 contact each other, the arc-shaped guide plate 321 and the two limiting plates 323 form a ring-like structure, so that the end of the barbell is fitted inside the ring (although the barbell will vibrate up and down when it falls and contacts the two buffer components 31, the buffer components 31 can dissipate the force of the falling barbell, so that the up and down jumping amplitude of the barbell when it contacts the buffer components 31 is small). The device uses the pressure applied to the compression component when the barbell falls to compress the gas inside the compression component and force it into the two arc-shaped guide plates 321 at the corresponding positions, so that the two limiting plates 323 within the arc-shaped guide plate 321 extend out, thereby clamping the end of the barbell and preventing the barbell from shifting position and hitting the athlete when subjected to the opposite force of the two buffer components 31. Example 1

[0018] like Figure 5 and Figure 6 As shown, in this embodiment, the compression component includes an airbag 324 disposed inside the storage shell 312 at the corresponding position. The airbag 324 is fixedly connected to a connecting pipe that penetrates the storage shell 312 at the corresponding position. A three-way pipe 325 is fixedly connected to the bottom end of the connecting pipe. Both ends of the three-way pipe 325 are fixedly connected to air pipes 326 that are fixedly connected to the arc-shaped guide plate 321 at the corresponding position. The arc-shaped guide plate 321 has a T-shaped air hole in the middle. The arc of the arc-shaped guide plate 321 is greater than 180 degrees. A sealing gasket is provided on the outside of the limiting plate 323.

[0019] In this embodiment, when the athlete falls due to exhaustion, the barbell is unloaded by the two buffer components 31, preventing it from bouncing excessively due to the reverse force. During the fall, without the support of the athlete's arms, the pressure exerted by the barbell on the buffer components 31 upon initial contact is very high, thus also very high, on the airbag 324. Under this pressure, the gas inside the airbag 324 is released through the three-way tube 325 and the air tube 326. The barbell is pressed into the arc-shaped guide plate 321 at the corresponding position, causing the two limiting plates 323 inside the arc-shaped guide plate 321 to be pushed out. As shown in the figure, both the slide 322 and the limiting plate 323 are arc-shaped. Therefore, after the limiting plate 323 is pushed out, the two limiting plates 323 and the arc-shaped guide plate 321 form a ring-like structure, which makes the barbell clamped in the ring. Although the barbell will still bounce in the four rings, the barbell will avoid large positional changes during the bounce due to the obstruction of the barbell plates. Example 2

[0020] like Figure 3 and Figure 4 As shown, in this embodiment, a pressure plate is slidably sleeved inside the storage shell 312. A telescopic plate 313 is fixedly connected to the top surface of the pressure plate and slides through the moving plate 311 at the corresponding position. An arc-shaped groove is opened on the top surface of the telescopic plate 313, and a buffer pad 314 is fixedly connected inside the arc-shaped groove. Two symmetrical sliding holes 12 are opened through the side of the support frame 1. A sliding rod 13 is fixedly connected between the two ends inside the sliding hole 12. A slider 315 is slidably connected through the outer wall of the sliding rod 13 and is fixedly connected to the moving plate 311 at the corresponding position. A spring 316 is fixedly connected between the slider 315 and the sliding hole 12 at the corresponding position. A connecting block 317 is fixedly connected to the top of both sides of the telescopic plate 313. A spring 318 is fixedly connected between the connecting block 317 and the moving plate 311 at the corresponding position.

[0021] In this embodiment, the impact force generated by the falling barbell is dissipated by the elastic action of spring 316, spring 318 and buffer pad 314, which reduces the amplitude of the barbell's bounce on the two telescopic plates 313. Furthermore, the elastic action of the two springs 316 can reduce the downward travel of the moving plate 311, thereby protecting the athlete over a wider range.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0023] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
