Description
Technical Field
[0001] This application relates to the field of sports equipment technology, specifically a badminton racket with an adjustable center of gravity. Background Technology
[0002] The badminton racket is the core equipment for playing badminton. Currently, badminton rackets typically have a fixed, integrated head, shaft, and handle, or while detachable, the center of gravity cannot be adjusted. The racket's center of gravity (balance point) is one of the key parameters affecting racket performance. A racket with its center of gravity closer to the head is heavier, resulting in more powerful shots, suitable for offensive playing styles; a racket with its center of gravity closer to the handle is lighter, allowing for faster swing speeds and greater agility, suitable for defensive and control-oriented playing styles.
[0003] Current racket center of gravity adjustment involves fine-tuning the center of gravity by wrapping additional buffer film or attaching weight plates. These methods have the following drawbacks: Inconvenient adjustment: Once the adjustment is completed, it is difficult to change it quickly and steplessly, affecting the feel: The added weight may change the original shape and thickness of the handle, affecting the grip comfort; Inaccurate and unstable: The position and weight of hand-wrapped or attached weights are not accurate, and they may loosen or fall off during strenuous exercise, making them inconvenient to use.
[0004] Therefore, this application provides a badminton racket with an adjustable center of gravity to solve the above problems. Utility Model Content
[0005] This application provides a badminton racket with an adjustable center of gravity, aiming to solve the problems mentioned in the background art where the existing racket center of gravity is adjusted by additionally wrapping a buffer film or attaching weight plates. These methods have the following drawbacks: inconvenient adjustment: once the adjustment is completed, it is difficult to change it quickly and steplessly, affecting the feel; the added weight may change the original shape and thickness of the handle, affecting the grip comfort; inaccurate and unstable: the position and weight of the manually wrapped or attached weight are inaccurate, and may loosen or fall off during vigorous exercise, making it inconvenient to use.
[0006] To achieve the above objectives, this application provides the following technical solution: a badminton racket with an adjustable center of gravity, wherein the badminton racket with an adjustable center of gravity includes an adjustment mechanism; To address the shortcomings of existing racket center-of-gravity adjustments, which rely on methods like wrapping additional cushioning film or attaching weight plates, the proposed adjustment mechanism addresses these issues. These methods suffer from drawbacks such as: inconvenient adjustment (once adjusted, quick and stepless changes are difficult, affecting feel; added weights may alter the original shape and thickness of the handle, impacting grip comfort); and inaccuracy and instability (hand-wrapped or attached weights are inaccurate in position and weight, and may loosen or fall off during vigorous activity). The proposed mechanism includes a handle, one end of which is fixedly connected to a shaft, and the other end of the shaft is fixedly connected to a frame. A weight cavity is provided inside the handle. The racket is equipped with a counterweight block. A groove is formed at the top of the handle, and a threaded groove is formed inside the counterweight cavity. A threaded rod is installed inside the threaded groove, and a knob is fixedly connected to the top of the threaded rod. Rotating the knob causes the threaded rod to rotate, separating it from the threaded groove. This allows the counterweight block to slide within the counterweight cavity, thus changing the racket's center of gravity. A shim is placed over the threaded rod, and the knob causes the threaded rod to connect with the threaded groove, fixing the counterweight block inside the handle. This allows for easy adjustment of the racket's center of gravity according to usage needs, improving the racket's comfort and practicality. The operation is simple, quick, and convenient.
[0007] Preferably, in order to solve the problem of convenient adjustment of the counterweight position, the counterweight is cylindrical, and the top of the counterweight slides in conjunction with the sliding groove. The counterweight and the sliding groove are slidably connected, which can facilitate the adjustment of the counterweight position and make it convenient to use.
[0008] Preferably, in order to solve the problem of conveniently fixing the slide groove, the threaded rod is threadedly connected to the threaded groove, and a gasket is provided inside the slide groove. The gasket is sleeved on the outside of the threaded rod, and the threaded rod is threadedly connected to the threaded groove, which can conveniently fix the slide groove inside the handle and make it easy to use.
[0009] Preferably, in order to solve the problem of user comfort, the slide groove has a T-shaped cross-section, and the knob is located inside the slide groove. The slide groove has a T-shaped cross-section, the knob is located inside the slide groove, and the height of the knob is lower than the height of the slide groove, which can avoid protrusion and improve user comfort.
[0010] Preferably, in order to solve the problem of easy replacement of counterweights, one end of the racket handle is provided with an end cap, which is threadedly connected to the racket handle. The threaded connection between the end cap and the racket handle allows for easy replacement of counterweights of different materials and weights, making it convenient to use.
[0011] Preferably, in order to solve the problem of convenient use, the handle is covered with a rubber sleeve. The rubber sleeve can improve the grip friction and the comfort of use.
[0012] This adjustment mechanism involves rotating a knob, which causes the threaded rod to rotate, separating it from the threaded groove. This allows the counterweight to slide within the counterweight cavity, thus changing the racket's center of gravity. Alternatively, a shim can be fitted over the threaded rod, and the knob can connect the threaded rod to the threaded groove, securing the counterweight inside the handle. This allows for convenient adjustment of the badminton racket's center of gravity according to usage needs, improving comfort and practicality. The mechanism is simple, quick, and easy to use.

[0015] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.
[0016] Example 1 This embodiment provides a badminton racket with an adjustable center of gravity, such as... Figure 1-4 As shown, the center of gravity adjustable badminton racket includes an adjustment mechanism 1. The adjustable mechanism 1 allows for easy adjustment of the badminton racket's center of gravity according to usage needs, thus improving the racket's comfort and practicality. The operation is simple, quick, and convenient.
[0017] Specifically, the adjustment mechanism 1 includes a handle 11, a racket shaft 12 fixedly connected to one end of the handle 11, a racket frame 13 fixedly connected to one end of the racket shaft 12, a counterweight cavity 14 inside the handle 11, a counterweight block 15 inside the counterweight cavity 14, a sliding groove 16 on the top of the handle 11, a threaded groove 17 inside the counterweight cavity 14, a threaded rod 19 inside the threaded groove 17, and a knob 18 fixedly connected to the top of the threaded rod 19. In use, rotating the knob 18 causes the threaded rod 19 to rotate, separating it from the threaded groove 17. This allows the counterweight 15 to slide within the counterweight cavity 14, thus changing the racket's center of gravity. The shim 20 is then fitted over the threaded rod 19, and the knob 18 causes the threaded rod 19 to connect with the threaded groove 17, fixing the counterweight 15 inside the handle 11. This allows for easy adjustment of the badminton racket's center of gravity according to usage needs, improving comfort and practicality. The operation is simple, quick, and convenient. The threaded rod 19 and threaded groove 17 can use fine threads (such as M4×0.5) to improve locking accuracy and prevent loosening due to vibration. The shim 20 can be made of elastic materials (such as silicone or rubber), deforming during tightening to enhance locking force and provide cushioning.
[0018] Furthermore, the counterweight 15 is cylindrical, and the top of the counterweight 15 slides in conjunction with the slide groove 16. The counterweight 15 and the slide groove 16 are slidably connected, which makes it easy to adjust the position of the slide groove 16 and convenient to use. The counterweight 15 can be made of metal (such as tungsten steel, lead block, stainless steel) or high-density polymer material, and the weight can be selected in stages from 10g to 50g to meet different center of gravity adjustment needs. The outer surface of the counterweight 15 can be provided with anti-slip texture or coating to prevent unexpected sliding in the cavity 14.
[0019] Furthermore, the threaded rod 19 is threadedly connected to the threaded groove 17, and a washer 20 is provided inside the sliding groove 16. The washer 20 is sleeved on the outside of the threaded rod 19. The threaded rod 19 is threadedly connected to the threaded groove 17, which can easily fix the sliding groove 16 inside the handle 11, making it convenient to use.
[0020] The slide groove 16 has a T-shaped cross-section, and the knob 18 is located inside the slide groove 16. The height of the knob 18 is lower than the height of the slide groove 16 to avoid protrusion and improve user comfort. The T-shaped cross-section design of the slide groove 16 can cooperate with the T-shaped protrusion on the top of the counterweight 15 to ensure that the counterweight 15 can only slide along the direction of the slide groove 16, preventing rotation or displacement. A lubricating layer (such as a Teflon coating) can be provided on the inner wall of the slide groove 16 to reduce sliding friction.
[0021] Specifically, one end of the handle 11 is provided with an end cap 21, which is threaded to the handle 11. The threaded connection between the end cap 21 and the handle 11 allows for easy replacement of counterweights 15 of different materials and weights, making it convenient to use. A sealing ring can be provided between the end cap 21 and the handle 11 to prevent sweat or dust from entering the counterweight cavity 14 and affecting its service life.
[0022] Furthermore, a rubber sleeve 22 is provided on the outside of the handle 11. The rubber sleeve 22 provided on the outside of the handle 11 can improve the grip friction and the comfort of use.
[0023] The above are merely preferred embodiments of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
