Abstract
Description
Technical Field
[0001] This utility model relates to the field of sports equipment technology, specifically to an explosive power training device. Background Technology
[0002] With societal development and increased awareness of healthy living, ball sports such as badminton and tennis have become increasingly popular. However, in actual play, the explosive power required for hitting the ball necessitates coordinated body movements. The ability to generate explosive power from the extremities at the end of the power chain is the most direct requirement and the only way to transfer body power to the racket. This includes actions such as generating power from the fingers, wrist, and forearm pronation.
[0003] Currently, for the aforementioned whip-like explosive power training, there are two types of explosive power training devices on the market: magnetic and elastic. These existing devices have the following drawbacks: 1. Both magnetic and elastic models require a fixed direction of swing for the impact and receiving ends to properly collide and produce a sound to remind the user whether the force applied during the strike is correct; 2. ... Figure 1 As shown, when using the magnetic version, because the magnetic end A and the impact end B are magnetically connected, when the user is training the upward flicking motion, after the swing, the impact end B moves away from the magnetic end A due to centrifugal force, and then stays at the impact end C under the influence of gravity, unable to magnetically return to the magnetic end A. It is necessary to manually lift it to magnetically return the impact end B and the magnetic part A to their original positions. Thirdly, it does not have a structure to adjust the force level, and cannot meet the explosive power training needs of users at different levels.
[0004] Therefore, the applicant hereby proposes an explosive power training device to solve the aforementioned problems. Utility Model Content
[0005] To address the shortcomings of existing technologies, this invention provides an explosive power training device.
[0006] The technical solution of this utility model is as follows:
[0007] This utility model provides an explosive power training device, including a handle, an impact member, an elastic member, and a limiting member; the front end of the handle has an impact groove, and the rear end of the handle has a travel groove that communicates with the impact groove and the external space respectively; the impact member is slidably disposed in the impact groove; the limiting member is fixedly disposed in the travel groove; the elastic member is disposed in the travel groove; the inner end of the elastic member is connected to the impact member; and the outer end of the elastic member is adjustablely connected to the limiting member.
[0008] Furthermore, the impact member includes an impact post, on which a connecting pin is provided, and the inner end of the elastic member is connected to the connecting pin.
[0009] Furthermore, the limiting member includes a limiting plate, the limiting plate having a limiting hole communicating with the outside, and the outer end of the elastic member having multiple limiting blocks along its length direction, the diameter of the limiting hole being larger than the elastic member and smaller than the limiting blocks.
[0010] Furthermore, the limiting member includes a limiting plate, with limiting holes and travel holes respectively opened at both ends of the limiting plate. The limiting holes and travel holes are connected by a guide hole. The outer end of the elastic member is provided with a plurality of limiting blocks along its length direction. The diameter of the limiting hole is larger than that of the elastic member and smaller than that of the limiting block. The diameter of the travel hole is larger than that of the limiting block.
[0011] Furthermore, the elastic element is an elastic rope.
[0012] Furthermore, the surface of the impact component is smooth.
[0013] Furthermore, a metal sheet is fixed on the inner side of the front end of the impact groove.
[0014] Furthermore, a buffer material is fixed on the inner side of the rear end of the impact groove or on the rear end of the impact member.
[0015] Furthermore, the front and rear ends of the handle are transitioned by a bevel or arc surface, and the diameter of the rear end of the handle is larger than the diameter of the front end.
[0016] Furthermore, a storage cover is threaded onto the rear end of the handle.
[0017] The beneficial effects achieved by this utility model are as follows:
[0018] The explosive power training device provided by this utility model allows the user to hold the device and swing it in any direction to accelerate during explosive power training. The impacting parts will directly impact the front end of the impact groove due to centrifugal force. The user can judge the magnitude of the explosive power and whether the way of hitting the ball is correct and effective based on the presence and volume of the impact sound, thereby obtaining feedback on the training effect and making it convenient for the user to make corresponding adjustments.
[0019] Because of the presence of the elastic element, when users are training the upward flicking of the ball, they do not need to manually lift it so that the impact element can be quickly reset, which improves training efficiency and effectiveness.
[0020] By manually stretching the outer end of the elastic element and allowing the appropriate limiting block to pass through the stroke hole and slide into the limiting hole, the training gear can be changed, which can meet the explosive power training needs of users at different levels.

[0026] To facilitate understanding of this utility model by those skilled in the art, the specific embodiments of this utility model are clearly described below with reference to the accompanying drawings. Obviously, the specific embodiments described are merely preferred embodiments of this utility model, and not all embodiments.
[0027] like Figure 1-5 As shown, the present invention provides an explosive power training device for explosive power training in ball sports such as badminton and tennis; it includes a handle 1, an impact member 2, an elastic member 3, and a limiting member 4; the front end of the handle 1 has an impact groove 11 along its length direction, and the rear end of the handle 1 has a travel groove 12 along its length direction, which is connected to the impact groove 11 and the external space respectively; the impact member 2 is slidably disposed in the impact groove 11; the limiting member 4 is fixedly disposed in the travel groove 12 at one end away from the impact groove 11; the elastic member 3 is disposed in the travel groove 12; the inner end of the elastic member 3 is connected to the impact member 2; and the outer end of the elastic member 3 is adjustablely connected to the limiting member 4.
[0028] The impact component 2 includes a vertically hollow impact column 21, on which a connecting pin 22 is integrally constructed. The inner end of the elastic component 3 is connected to the connecting pin 22, including but not limited to hanging or binding methods. In another embodiment, the impact column 21 and the connecting pin 22 are separate. Specifically, the impact column 21 has a slot for inserting the connecting pin 22. During explosive power training, the user can hold the device and choose any direction to accelerate the swing of the explosive power trainer. The impact component will directly impact the front end of the impact slot due to centrifugal force. The user can judge the magnitude of the explosive power and whether the way of hitting the ball is correct and effective based on the presence and volume of the impact sound, thereby obtaining feedback on the training effect and making corresponding adjustments for the user.
[0029] The limiting component 4 includes a limiting plate 41, on which a limiting hole 411 communicating with the outside is provided. The outer end of the elastic component 3 is provided with a plurality of limiting blocks 31 that are adjustablely connected to the limiting hole 411 along its length direction. These include, but are not limited to, knots, spheres, cubes, and discs, with knots being preferred in this embodiment. The diameter of the limiting hole 411 is larger than the diameter of the elastic component 3, and the diameter of the limiting block 31 is larger than the diameter of the limiting hole 411. By manually stretching the outer end of the elastic component and disengaging the limiting block from the limiting hole, the elastic component is pulled out of the limiting hole while simultaneously stretching the elastic component to select a suitable limiting block and sliding it into the limiting hole to make contact with it. This completes the function of changing training levels and can adapt to the explosive power training needs of users at different levels.
[0030] In this embodiment, the elastic element 3 is preferably an elastic rope; because of the presence of the elastic rope, when the user is training the upward flicking of the ball, there is no need to manually lift it to reset the impact element.
[0031] The impact element 2 has a smooth surface and is preferably made of metal in this embodiment, including but not limited to iron, aluminum, alloys, etc.; to increase the sound generated by the impact so as to remind the user to use it.
[0032] A metal sheet, including but not limited to iron, aluminum, alloy, etc., is fixed on the inner side of the front end of the impact groove 11 to amplify the sound generated by the impact, so as to remind the user.
[0033] The inner side of the rear end of the impact groove 11 or the rear end of the impact member 2 is fixed with a buffer material to prevent sound from being emitted when rebounding. The buffer material includes, but is not limited to, sponge, foam plastic, etc., and sponge is preferred in this embodiment.
[0034] The front and rear ends of the handle 1 are transitioned by a bevel or a rounded surface. In this embodiment, a bevel transition is preferred. The diameter of the rear end of the handle 1 is larger than that of the front end. This reduces the weight of the front end, optimizes the overall weight ratio of the auxiliary grip, and reduces production costs.
[0035] The handle 1 has a threaded cover 5 at its rear end for covering the elastic rope, thus preventing accidental contact with the elastic rope during training.
[0036] The outer periphery of the rear end of the handle 1 is provided with anti-slip texture to prevent the user's hand from slipping.
[0037] The handle 1 is made of plastic, which further reduces the overall weight and makes it easier for trainees to use during training.
[0038] Example 2:
[0039] The limiting member 4 includes a limiting plate 41, with limiting holes 411 and travel holes 412 respectively opened at both ends of the limiting plate 41. The limiting holes 411 and travel holes 412 are connected by a guide hole 413. The outer end of the elastic member 3 is provided with a plurality of limiting blocks 31 along its length direction, which can slide and contact with the limiting holes 411, travel holes 412 and guide holes 413. The limiting blocks 31 include, but are not limited to, knots, spheres, square pieces and round pieces, etc., and in this embodiment, knots are preferred. The diameter of the limiting hole 411 is larger than the diameter of the elastic member 3, the diameter of the limiting block 31 is larger than the diameter of the limiting hole 411, and the diameter of the travel hole 412 is larger than the diameter of the limiting block 31. By manually stretching the outer end of the elastic member and making the appropriate limiting block pass through the travel hole and slide along the guide hole into the limiting hole, the training level can be changed, which can adapt to the explosive power training needs of users at different levels.
