Abstract
Description
Technical Field
[0001] This utility model belongs to the field of sports training equipment, and in particular relates to a hexagonal barbell trainer. Background Technology
[0002] Most sports rely on force exerted in the sagittal plane. Taking short-distance sprinting as an example, at maximum speed, one leg pushes off the ground in a short period (usually 80-120 ms) to apply sagittal force. The magnitude of this force has a significant impact on running speed. Common sagittal plane exercises such as barbell squats and barbell deadlifts are classic structural resistance training. To enhance the safety of practicing these movements, the Smith machine with a fixed trajectory was developed. However, the traditional Smith machine connects to a barbell. Whether it's a Smith machine squat or a deadlift, the distribution of pressure does not conform to the body's center of gravity. In a barbell squat, the pressure is concentrated on the upper back of the neck, and in a barbell deadlift, the pressure is concentrated in front of the body's center of gravity. Both of these exert significant shearing forces on the spine, easily leading to lower back pain. The hexagonal bar 2 allows the person to stand in the center of the barbell (with a hexagonal standing hole 21 in the center). At the same time, the two ends of the hexagonal barbell standing hole are equipped with n-shaped handles 22. Compared to a regular barbell, the shearing force on the spine is smaller when performing structural deadlift exercises. However, if the hexagonal barbell accidentally slips out of the hands while the trainee is standing in the standing hole in the middle of the hexagonal barbell, it can easily cause injury. Utility Model Content
[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a hexagonal barbell trainer that is simple in structure, convenient for training, and safe.
[0004] To achieve the above objectives, the technical solution of this utility model is as follows: A hexagonal barbell trainer includes a training frame, a hexagonal barbell rod, and two shock absorbers. The training frame has two vertically arranged sliding shafts spaced apart in the left-right direction. The hexagonal barbell rod is horizontally arranged in the left-right direction and is vertically slidably connected to the two sliding shafts. The two handles of the hexagonal barbell rod are located between the two sliding shafts. Both ends of the hexagonal barbell rod are provided with barbell plates. The two shock absorbers are respectively arranged on both sides of the training frame and located below the two barbell plates.
[0005] The beneficial effects of the above technical solution are as follows: By combining the hexagonal barbell with the frame in this way, the hexagonal barbell can only move within the vector plane relative to the two sliding axes during training, while the trainee stands in the standing hole in the middle of the hexagonal barbell. This reduces the shear force on the trainee's spine. At the same time, the hexagonal barbell is limited in the forward and backward directions by the two sliding axes, so even if it is released during training, it will not cause any injury to the trainee. In addition, shock absorbers are installed under the two weight plates, so that after the hexagonal barbell is released, the weight plates fall onto the shock absorbers, thus reducing the impact on the ground.
[0006] The training frame described in the above technical solution is a hollow n-shaped frame, and the two sliding shafts are both located in the middle of each side of the training frame.
[0007] The beneficial effect of the above technical solution is that it makes the entire training rack more stable when placed on the ground.
[0008] The shock-absorbing component described in the above technical solution includes a height adjusting component and a buffer pad, with the buffer pad disposed at the upper end of the height adjusting component.
[0009] The beneficial effect of the above technical solution is that the height of the cushioning pad can be conveniently adjusted as needed.
[0010] The shock absorber in the above technical solution also includes a damping component, which is disposed between the height adjustment component and the buffer pad, and is used to adjust the elasticity of the shock absorber.
[0011] The beneficial effect of the above technical solution is that the damping effect of the shock absorber can be adjusted by the damping component.
[0012] The damping component described in the above technical solution includes multiple air damping springs spaced apart between the height adjustment component and the buffer pad.
[0013] The beneficial effect of the above technical solution is that by using multiple air damping springs as damping components, the elastic force can be flexibly adjusted as needed.
[0014] The damping component described in the above technical solution includes five air damping springs, one of which is located in the middle between the height adjustment component and the buffer pad, and the remaining four air damping springs are located at the four corners between the height adjustment component and the buffer pad.
[0015] The beneficial effects of the above technical solution are that it makes the cushioning pad more stable when installed on the height adjustment component, and at the same time, the overall elasticity distribution is more balanced.
[0016] The height adjustment component described in the above technical solution is a double scissor lift platform.
[0017] The advantages of the above technical solution are that it has a simple structure and high structural strength.
[0018] The buffer pad described in the above technical solution includes a base plate and a flexible pad layer disposed on the upper end of the base plate.
[0019] The beneficial effect of the above technical solution is that it can avoid making a loud noise when the barbell plates collide with the cushioning pad.
[0020] The above technical solution also includes a force measuring plate disposed between the two sliding shafts and located below the hexagonal barbell rod.
[0021] The beneficial effects of the above technical solution are as follows: trainees can stand on the force plate to train, and the force plate can monitor the mechanical data during training, so as to make it easier to adjust the training load and monitor the athlete's physical condition.
[0022] In the above technical solution, both ends of the hexagonal barbell are vertically provided with sliding sleeves that are slidably sleeved on the two sliding shafts.
[0023] The beneficial effect of the above technical solution is that it makes the sliding installation of the hexagonal barbell on the slide shaft more effective. Attached Figure Description

Detailed Implementation
[0031] The principles and features of this utility model are described below with reference to the accompanying drawings. The examples given are for illustrative purposes only and are not intended to limit the scope of this utility model. The utility model is described more specifically in the following paragraphs by way of example with reference to the accompanying drawings. The advantages and features of this utility model will become clearer from the following description and claims. It should be noted that the drawings are all in a very simplified form and use non-precise proportions, and are only used to facilitate and clarify the illustration of the embodiments of this utility model.
[0032] like Figures 1-4 As shown, an embodiment provides a hexagonal barbell training device, including a training frame 1, a hexagonal barbell 2, and two shock absorbers 3. The training frame 1 has two vertically arranged sliding shafts 11 spaced apart in the left-right direction. The hexagonal barbell 2 is horizontally arranged in the left-right direction and vertically slidably connected to the two sliding shafts 11. The two handles of the hexagonal barbell 2 are located between the two sliding shafts 11. Both ends of the hexagonal barbell 2 are provided with barbell plates 4. The two shock absorbers 3 are respectively arranged on both sides of the training frame 1 and located between the two barbell plates. Below plate group 4, the hexagonal barbell is connected to the frame in this way, so that the hexagonal barbell can only move in the vector plane relative to the two sliding axes during training. The trainee stands in the standing hole in the middle of the hexagonal barbell, which reduces the shear force on the trainee's spine. At the same time, the hexagonal barbell is limited in the front and back directions by the two sliding axes, so even if it is released during training, it will not cause any injury to the trainee. In addition, shock absorbers are set under the two barbell plate groups, so that if the hexagonal barbell is released, the barbell plates will fall on the shock absorbers, which reduces the impact on the ground.
[0033] In the above technical solution, both ends of the hexagonal barbell 2 are vertically provided with sliding sleeves 23 that are slidably sleeved on the two sliding shafts 11, which makes the sliding installation of the hexagonal barbell on the sliding shafts more effective.
[0034] like Figure 1 and Figure 2 As shown, in this embodiment, the two sides of the training frame can be fixed to the ground with expansion bolts, and the two shock absorbers are located on the outside of the training frame, which can also be fixed to the ground with expansion bolts.
[0035] like Figure 3 and Figure 4 As shown, the training frame 1 in the above technical solution is a hollow n-shaped frame, and the two sliding shafts 11 are both set in the middle of each side of the training frame 1, which makes the stability of the entire training frame standing on the ground better.
[0036] like Figure 5As shown, the shock absorber 3 in the above technical solution includes a height adjustment component 31 and a buffer pad 32. The buffer pad 32 is disposed at the upper end of the height adjustment component 31, so that the height of the buffer pad can be conveniently adjusted as needed. Specifically, the shock absorber 3 also includes a damping component 33, which is disposed between the height adjustment component 31 and the buffer pad 32. It is used to adjust the elasticity of the shock absorber 3, so that the shock absorption effect of the shock absorber can be adjusted by the damping component.
[0037] like Figure 5 As shown, the damping element 33 in the above technical solution includes multiple air damping springs 331 spaced apart between the height adjusting element 31 and the buffer pad 32. By using multiple air damping springs as damping elements, the elastic force can be flexibly adjusted as needed. In this embodiment, the elastic force can be adjusted by adjusting the amount of air in the air damping springs.
[0038] like Figure 6 As shown, the damping component 33 in the above technical solution includes five air damping springs 331. One of the air damping springs 331 is located in the middle between the height adjusting component 31 and the buffer pad 32, and the remaining four air damping springs 331 are located at the four corners between the height adjusting component 31 and the buffer pad 32. This makes the buffer pad more stable when installed on the height adjusting component, and the overall elasticity distribution is more balanced.
[0039] The height adjustment component 31 described in the above technical solution is a double scissor lift platform, which has a simple structure and high structural strength.
[0040] like Figure 5 As shown, the buffer pad 32 in the above technical solution includes a base plate 321 and a flexible pad layer 322 disposed on the upper end of the base plate, which can avoid making a loud noise when the barbell plate group hits the buffer pad; preferably, the flexible pad layer 322 is a rubber pad, which has good durability. Specifically, the flexible pad layer can be made of multiple layers of rubber pads similar to the material of car tires.
[0041] like Figure 2 As shown in the figure, in this embodiment, a force plate 5 (similar to a digital display scale, which will not be described in detail here) can be set at the lower inner end of the training frame where the trainee stands. Specifically, the force plate is placed below the standing hole. At this time, the trainee stands on the force plate for training. The force plate is used to measure the changes in the trainee's own weight and the downward pressure of the barbell during training. The trainee can adjust the elasticity of the damping component according to the measurement data of the force plate.
[0042] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model in any way. Those skilled in the art can readily implement this utility model based on the accompanying drawings and the above description. However, any modifications, alterations, or equivalent variations made by those skilled in the art without departing from the scope of the utility model's technical solution, utilizing the disclosed technical content, are considered equivalent embodiments of this utility model. Furthermore, any equivalent changes, alterations, or variations made to the above embodiments based on the essential technology of this utility model are still within the protection scope of this utility model's technical solution.
