Description

Technical Field

[0001] This utility model relates to the field of fitness equipment technology, specifically a strength training device that uses an elastic bar as a resistance source. Background Technology

[0002] With rapid societal development and improved living standards, people's demand for fitness and exercise is increasing, going beyond just daily diet and lifestyle. Strength training is an indispensable part of fitness, not only increasing muscle endurance and strength but also promoting fat burning and boosting basal metabolism. As public awareness of strength training grows, home strength training equipment is becoming increasingly popular among young people. Existing strength training equipment primarily uses weights as resistance, which can satisfy various muscle strength training needs. However, these products are often bulky, generate significant inertia during training, are expensive, take up a lot of space, and produce noise and vibration from the collision of the weights, making them unsuitable for home use.

[0003] In response to the above phenomena, a strength training device that uses elastic bars as a resistance source could be provided. It would not only take up little space and be easy to move, but also reduce the noise and vibration caused by the impact of the weights when training various muscles, and reduce the inertial impact during movement recovery. It is worth promoting and applying. Summary of the Invention

[0004] The purpose of this invention is to address the aforementioned shortcomings by providing a strength training device that uses an elastic bar as a resistance source. This device not only reduces noise and vibration, decreases inertial impact, and enhances the exercise experience, but also takes up little space.

[0005] To achieve the above objectives, a strength training device using an elastic bar as a resistance source is designed, comprising a frame 1, pulleys 2, a resistance system 3, a tension rope 4, and a handle 6. The frame 1 is fixedly equipped with pulleys 2 at both the top and bottom. The resistance system 3 includes an elastic bar 3D, the bottom of which is fixedly connected to the frame 1. The top of the elastic bar 3D is connected to one end of the tension rope 4. The tension rope 4 is wound sequentially around the pulleys 2 at the bottom and top of the frame 1. The other end of the tension rope 4 is connected to a handle 6 for stretching training.

[0006] Furthermore, the frame 1 is composed of an upper crossbar 1A, a vertical bar 1B and a lower crossbar 1C. The upper crossbar 1A and the lower crossbar 1C are respectively fixed to the upper and lower ends of the vertical bar 1B. The upper crossbar 1A, the vertical bar 1B and the lower crossbar 1C form an "I" shaped structure.

[0007] Furthermore, the resistance system 3 also includes a pull ring 3A, a fixing block 3B, and a support plate 3C. The bottom end of the elastic rod 3D is mounted on the fixing block 3B. The fixing block 3B is fixedly connected to the upright 1B of the frame 1 through the support plate 3C. A pull ring 3A is mounted on the upper side of the elastic rod 3D. A hook 5 is suspended on the pull ring 3A. One end of the tension rope 4 is connected to the hook 5.

[0008] Furthermore, the elastic rods 3D are symmetrically distributed on the left and right sides, and pulleys 2 are fixed on both sides of the upper crossbar 1A and the lower crossbar 1C of the frame 1, respectively.

[0009] Furthermore, at least two elastic rods 3D are provided on the left or right side, each with a different diameter, and arranged in order of increasing diameter, thereby easily achieving multi-resistance conversion.

[0010] Furthermore, the fixing block 3B is provided with mounting holes of corresponding size, and the elastic rod 3D is installed in the mounting holes according to the corresponding size holes.

[0011] Furthermore, the hook 5 is suspended from a pull ring 3A on the upper side of the elastic rod 3D, or from multiple pull rings 3A on the upper side of the elastic rod 3D, thereby increasing resistance and allowing for free combination.

[0012] Furthermore, the elastic rod 3D is made of nylon composite material, which has good resilience, high fatigue resistance, and is not easy to break.

[0013] Compared with the prior art, this utility model has the following advantages: (1) This utility model uses an elastic bar as a resistance source in traditional strength training equipment, which can not only improve noise and vibration, reduce inertial impact and improve the experience during exercise, but also has the advantages of small footprint, easy to move and can be used at home. (2) The elastic rod of this utility model is made of nylon composite material, which has good resilience, high fatigue resistance and is not easy to break; (3) This utility model can use elastic bars of various specifications. Each specification is symmetrically distributed on the left and right. Each group can be used alone or in combination, so as to easily realize the conversion of multiple resistances. (4) The hook of this utility model can be suspended on one elastic bar pull ring or on multiple elastic bar pull rings on the same side at the same time, thereby increasing the resistance and can be freely combined; In summary, this utility model not only occupies little space and is easy to move, but also reduces noise and vibration caused by the impact of the counterweights when training various muscles, and reduces the inertial impact during movement recovery, thus improving the experience of exercise. It is worthy of widespread application. Attached Figure Description
