Description

Technical Field

[0001] This utility model relates to the field of sports equipment, and in particular to a swing practice device with a shock absorption mechanism. Background Technology

[0002] Current swing practice devices involve the training ball directly impacting the racket frame during the hitting motion, relying on its elasticity to return to its original position. However, prolonged use can lead to deformation or even damage to the top of the racket frame. Furthermore, the training ball has relatively limited stored elastic potential energy and poor coaxiality with the sliding direction, which cannot guarantee a complete return to its original position. Simultaneously, the kinetic energy generated by the impact causes overall racket vibration, potentially interfering with the user's stable grip. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the technical problems in the prior art and provide a swing practice device with a shock absorption mechanism.

[0004] The technical solution adopted by this utility model to solve its technical problem is: A swing practice device with a shock absorption mechanism, comprising: The racket frame and the racket handle are connected to each other; The ball-hitting simulation mechanism is set inside the racket frame. The ball-hitting simulation mechanism includes a sliding support part and a sliding part. The sliding support part has a top part and a bottom part, which are respectively stationary relative to the racket frame. The sliding part is slidably connected to the sliding support part. During the swing, the sliding part moves toward the top part of the sliding support part and during the return to its original position, it moves toward the bottom part of the sliding support part. It also includes a shock-absorbing mechanism, which is located at the top of the sliding support. The shock-absorbing mechanism includes a rebound pushing part and an elastic element. The rebound pushing part is elastically connected through the elastic element and is used to contact the sliding part. The rebound pushing part has an elastic floating axis and is coaxial with the sliding axis of the sliding part.

[0005] In one possible implementation, the sliding support includes a guide rod disposed between the end and the top of the sliding support. A sliding sleeve is slidably connected to the guide rod, and a training ball is sleeved on the outside of the sliding sleeve. The training ball contacts the rebound push part.

[0006] As one possible implementation, a sliding guide is provided at the top of the racket sliding support, the sliding guide and the sliding part are coaxially arranged, and the rebound pushing part is slidably connected to the racket frame through the sliding guide.

[0007] As one possible implementation, a limiting mechanism is provided between the rebound pushing part and the sliding guide part. The limiting mechanism includes two sets of limiting end faces and a contact part. The two sets of limiting end faces are respectively provided on both ends of the rebound pushing part, and the contact part is provided on the sliding guide part and contacts the limiting end faces. The contact part is located between the two sets of limiting end faces.

[0008] In one possible implementation, the sliding guide includes a sliding seat fixedly connected to the racket frame, the contact part includes a sliding ring disposed in the middle of the sliding seat, and the rebound pushing part includes a floating sleeve that is slidably connected to the inner ring of the sliding ring. Limiting rings are provided at both ends of the floating sleeve, and the limiting end face is disposed on one axial side of the limiting ring.

[0009] As one possible implementation method, the elastic element is a coil spring.

[0010] As one possible implementation, an extension ring is integrally provided on the limiting ring at one axial end of the floating sleeve, and an inlay groove is provided between the extension ring and the limiting ring, with the end of the elastic element fixed into the inlay groove.

[0011] In one possible implementation, a sliding hole is provided in the middle of the spring-loaded push part, one axial end of the guide rod is embedded in the sliding hole, and the spring-loaded push part is slidably connected to the guide rod through the sliding hole.

[0012] As one possible implementation, the racket frame has a frame top and a frame end, with an inlay hole provided at the frame end, and the other end of the guide rod axially connected to the frame top.

[0013] As one possible implementation, the guide rod has a hollow structure, and the part of the guide rod that is embedded in the inlay hole is provided with a support post.

[0014] The beneficial effects of this utility model are: This invention provides a rebound pushing part at the top of the racket frame, which is supported by an elastic element. When the training ball is swung out, it can buffer and reduce the impact on the racket frame, while improving the rebound efficiency of the training ball. The sliding guide can provide a precisely directional rebound force; The contact block can serve as an independent structure to replace the elastic element in contact with the training ball. If the elastic damping mechanism is a metal spring, the contact block can reduce the likelihood of damage to the training ball. The limiting mechanism can prevent the sliding guide from moving freely on the guide rod, which would affect the smooth movement of the training ball. Moreover, if the limiting mechanism moves freely, it will consume additional kinetic energy. The sliding guide mechanism and the limiting mechanism are integrated into one structure, which optimizes the structural complexity and improves stability; Coil springs have a higher degree of coaxiality in their rebound direction and a longer lifespan; The elastic element is connected to the extension ring, so that there is no gap when the elastic element contacts the rebound push part and the training ball, thus improving the transmission efficiency of elastic force. The guide rod end is supported by a sliding hole, which eliminates the need for an additional support mechanism at the end of the guide rod, thus simplifying the structure. Support columns can enhance the strength of the guide rod end and reduce the impact of shear force between the guide rod end and the inlay hole end on the guide rod strength.

[0018] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention. Example

[0019] like Figure 1 , Figure 2 , Figure 3 The swing practice device mainly consists of a racket frame 1, a hitting simulation mechanism, and a shock absorption mechanism. The racket frame 1 is in the shape of a traditional racket, with the top 3 and the bottom 4 of the frame 1 at its two ends. The bottom 4 of the frame is fitted with a racket handle 2 for easy gripping and operation. The hitting simulation mechanism is located inside the racket frame 1.

[0020] The ball-hitting simulation mechanism includes a sliding support and a sliding part, with a shock-absorbing mechanism located at the end of the sliding support. The sliding support includes a guide rod 5. In this embodiment, the guide rod 5 is arranged along the main axis of the racket frame 1, that is, the axis of the guide rod 5 is coaxial with the axis of the racket handle 2. The frame end 4 and frame top 3 are in the same axial position as the top and end of the guide rod 5 (sliding support). A training ball 6 is slidably connected to the guide rod 5, and the training ball 6 can slide freely along the guide rod 5 during the swing and preparation process.

[0021] Specifically, such as Figure 2and Figure 3 A fixing ring 9 is embedded and fixed at the end 4 of the frame. An inlay hole is provided in the fixing ring 9, which extends outward to the end 4 of the frame. One axial end of the guide rod 5 is fixedly embedded in the inlay hole. To ensure structural stability, a support column 10 is provided at the part of the guide rod 5 that is embedded in the inlay hole. The guide rod 5 adopts a hollow structure, which reduces the overall weight while ensuring strength. The other end of the guide rod 5 is connected to the top 3 of the frame through a shock absorption mechanism.

[0022] The training ball 6 is slidably connected to the guide rod 5 through the sliding sleeve 11. The sliding sleeve 11 can slide freely along the guide rod 5, allowing the training ball 6 to reciprocate on the guide rod 5. When swinging, the training ball 6 can simulate the vibration of the racket when hitting the damping mechanism at the end of the frame 4.

[0023] The shock-absorbing mechanism's rebound drive and sliding guide work together to achieve the buffering and rebound function of the sliding part. For example... Figure 2 and Figure 3 The sliding guide includes a sliding seat integrally fixed to the end 4 of the frame, and a sliding ring 7 integrally provided in the middle of the sliding seat. The spring-loaded pushing part is composed of a floating sleeve 8, which forms a sliding contact with the inner ring of the sliding ring 7, so that the floating sleeve 8 can slide smoothly along the axial direction of the sliding ring 7.

[0024] A limiting mechanism is provided between the floating sleeve 8 and the sliding guide. The limiting mechanism includes two sets of limiting rings at both ends of the floating sleeve 8. The axial side of the limiting ring forms a limiting end face, and the sliding ring 7 on the sliding seat serves as the contact part that contacts the limiting end face. The contact part is located between the two sets of limiting end faces, thereby effectively preventing the floating sleeve 8 from sliding excessively out of the normal working range and thus affecting the normal sliding of the sliding sleeve 11 on the analog ball.

[0025] like Figure 2 and Figure 3 The elastic element is a coil spring 13. An extension ring 12 is integrally provided on the limiting ring at one axial end of the floating sleeve 8. An inlay groove is formed between the extension ring 12 and the limiting ring. The end of the coil spring 13 is fixedly installed in the inlay groove to achieve elastic connection.

[0026] In one embodiment, a sliding hole is provided in the middle of the floating sleeve 8, and one axial end of the guide rod 5 is embedded in the sliding hole, so that a sliding connection is also formed between the guide rod 5 and the rebound pushing part, and the rebound pushing part has an elastic floating axis and is coaxial with the sliding axis of the training ball 6.

[0027] When the user grips the racket handle 2 and performs a swing, the sliding sleeve 11 on the training ball 6 slides along the guide rod 5 due to inertia and impacts the floating sleeve 8. The impact force generated during the impact simulates the vibration of the racket during a real shot. When the simulated ball impacts the end of the floating sleeve 8, the coiled spring 13 is compressed and undergoes elastic deformation, absorbing the impact force generated by the training ball 6 and acting as a buffer to reduce the direct impact on the racket frame 1, preventing deformation or damage. Under the action of the spring's elastic potential energy, the rebounding pusher pushes the training ball 6 in the opposite direction, causing it to slide along the guide rod 5 again, thus simulating the return process after a real shot. By repeatedly swinging the racket and hitting the training ball 6, the user can practice their swing and improve their hitting skills.

[0028] In various embodiments of this application, the guide rod 5 can also form a certain angle with the central axis of the racket frame 1 to enable practice of other swing actions and other hitting directions.

[0029] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
