Description

Technical Field

[0001] The utility model belongs to the technical field of sports equipment, and specifically refers to an arm strength exercise device for sports training. Background Technique

[0002] In the field of modern sports training, arm strength exercise devices are common and important training tools. However, for traditional arm strength exercise devices, such as dumbbells or spring arm strength exercisers with fixed resistance, the exercise intensity they provide is often fixed. For beginners, too high an initial intensity may cause injuries, while for athletes with a certain training foundation, the fixed intensity cannot meet their growing strength requirements. Content of the Utility Model

[0003] In view of the above situation, in order to overcome the defects of the prior art, the utility model provides an arm strength exercise device for sports training, effectively solving the problem of fixed exercise intensity.

[0004] In order to achieve the above functions, the technical solution adopted by the utility model is as follows: An arm strength exercise device for sports training, including a support plate, an adjustment component is provided on the support plate, two groups of movable plates are symmetrically provided on the adjustment component, a grip is fixed at the bottom end of the movable plate, a fixed bolt is fixed at the top end of the movable plate, and a strong spring is fixedly connected to the fixed bolt.

[0005] Preferably, the adjustment component includes an embedded groove and a bidirectional lead screw. The embedded groove is arranged in the support plate. Both ends of the bidirectional lead screw penetrate through the support plate and the side wall of the embedded groove and are rotatably arranged on the support plate. Rotating blocks are fixed at both ends of the bidirectional lead screw. Movable adjustment blocks are symmetrically and threadedly connected to the bidirectional lead screw. The movable plate is rotatably arranged on the movable adjustment block.

[0006] Preferably, anti-slip strips are provided on the outer side walls of the rotating block and the grip.

[0007] Preferably, the movable adjustment block closely adheres to the upper and lower walls of the embedded groove and slides relative to the embedded groove.

[0008] Preferably, a limiting plate is fixed on the outer side wall of the movable adjustment block close to the movable plate.

[0009] Preferably, a plurality of suction cups are fixed behind the support plate. The suction cups are vacuum suction cups made of rubber.

[0010] The beneficial effects achieved by the present utility model with the above structure are as follows: By driving the adjustment component to change the compression state of the spring, the exercise intensity is adjusted. If the initial length of the spring is longer and the compression amount is smaller, the elastic force that the user needs to overcome is smaller, and the exercise intensity is lower. When gradually shortening the initial length of the spring and increasing its compression amount, at this time, the user needs to use greater force to complete the same action, and the exercise intensity is increased. It is convenient and effective to adjust the exercise intensity and improve the flexibility of the device. Brief Description of the Drawings

[0016] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some embodiments of the present utility model, rather than all embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0017] In the description of the present utility model, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, it should not be construed as a limitation to the present utility model. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. The following further describes the present utility model in detail with reference to the drawings.

[0018] As Figures 1-4 shown, an arm strength exercise device for sports training proposed by the present utility model includes a support plate 1. An adjustment assembly 2 is provided on the support plate 1 to adjust the exercise intensity. Two groups of movable plates 3 are symmetrically provided on the adjustment assembly 2. A grip 6 is fixed to the bottom end of the movable plate 3, and a fixing bolt 4 is fixed to the top end of the movable plate 3. A strong spring 5 is fixedly connected to the fixing bolt 4. The adjustment assembly 2 includes an embedding groove 7 and a bidirectional lead screw 8. The embedding groove 7 is provided in the support plate 1. The two ends of the bidirectional lead screw 8 penetrate through the side walls of the support plate 1 and the embedding groove 7 and are rotatably provided on the support plate 1. Rotating blocks 9 are fixed to both ends of the bidirectional lead screw 8. Movable adjustment blocks 10 are symmetrically threadedly connected to the bidirectional lead screw 8. The movable plate 3 is rotatably provided on the movable adjustment block 10. Rotating the rotating block 9 drives the bidirectional lead screw 8 to rotate, and the bidirectional lead screw 8 drives the movable adjustment blocks 10 to approach or move away from each other, thereby driving the movable plates 3 to approach or move away from each other. By changing the compression state of the spring, the exercise intensity is adjusted. The movable adjustment block 10 abuts against the upper and lower walls of the embedding groove 7 and slides relative to the embedding groove 7 to limit the movable adjustment block 10. Anti-slip strips 13 are provided on the outer side walls of the rotating block 9 and the grip 6 to increase the friction and prevent slipping out of the hand.

[0019] As Figure 1 、 2 As shown in FIGS. 4, a limiting plate 11 is fixed to the outer side wall of the movable adjustment block 10 close to the movable plate 3 to limit one side of the movable plate 3, so that the movable plate 3 can only be pushed towards the middle direction, avoiding the rotation of the movable plate 3 due to its own elastic restoring force during the process of adjusting the strong spring 5 and ensuring the compression state.

[0020] As Figure 3 shown, a plurality of suction cups 12 are fixed behind the support plate 1. The suction cups 12 are vacuum suction cups 12 made of rubber material, which are convenient to fix the support plate 1 at a suitable position and are more convenient to use.

[0021] When in actual use, the device can be fixed at a suitable position through the suction cup 12, or the device can be directly picked up by holding the handle 6. Pushing the handle 6 drives the movable plate 3 to rotate. The rotation of the movable plate 3 stretches the strong spring 5, and the resistance of the strong spring 5 plays a role in exercising the arm. Rotating the rotating block 9 drives the bidirectional lead screw 8 to rotate, and the bidirectional lead screw 8 drives the moving adjustment blocks 10 to approach or move away from each other, thereby driving the movable plates 3 to approach or move away from each other. The movement of the movable plates 3 changes the compression state of the strong spring 5 to adjust the exercise intensity.

[0022] The above describes the present invention and its implementation manners. Such a description is not restrictive. What is shown in the drawings is only one of the implementation manners of the present invention, and the actual structure is not limited thereto. Generally speaking, if those of ordinary skill in the art are inspired by it and, without departing from the purpose of the creation of the present invention, design similar structural manners and embodiments to this technical solution without creative efforts, they shall fall within the protection scope of the present invention.
