Description

Technical Field

[0001] The utility model relates to the field of sports equipment, in particular to a sleeve-type racket. Background Art

[0002] Conventional molded racket bodies (such as tennis rackets) are hot-pressed together with the handle. The vibrations generated when hitting the ball are transmitted directly from the source to the handle. Specifically, the racket deforms upon impact, transforming into intense vibrations that are transmitted to the wrist and arm. Prolonged hitting can cause joint and muscle damage. Therefore, rackets require vibration-resistant structural designs. Utility Model Content

[0003] (1) Technical problems solved

[0004] In view of the deficiencies in the prior art, the utility model provides a sleeve-type racket which can play the role of vibration isolation, vibration reduction and buffering.

[0005] (2) Technical solution

[0006] A sleeve-type racket comprises a racket body, a handle of the racket body is sheathed with a sleeve body, a buffer layer is filled between the sleeve body and the handle, and a vibration-damping shrapnel is provided at the joint between the sleeve body and the handle.

[0007] Preferably, an upper cavity and a lower cavity are symmetrically provided in the sleeve body.

[0008] Preferably, the upper cavity and the lower cavity are respectively provided with vibration-damping springs at locations corresponding to the handles.

[0009] Preferably, the cross-sections of the upper cavity and the lower cavity are trapezoidal.

[0010] Preferably, the sleeve body is made of carbon fiber material.

[0011] Preferably, the buffer layer is made of epoxy resin foam material.

[0012] Preferably, the vibration-damping spring is a carbon fiber resin solidified plate or a glass fiber resin solidified plate.

[0013] Preferably, the sleeve body is assembled and fixedly connected to the racket body.

[0014] (3) Beneficial effects

[0015] Compared with the prior art, the present invention provides a new type of sleeve-type racket, which has the following advantages:

[0016] 1. Vibration isolation: The sleeve body of this product separates the handle and the racket body, which reduces the vibration of the system by controlling the transmission of vibration. An additional subsystem is used to separate the vibration source from the object to be reduced, so as to reduce the impact of the vibration source on the isolation object.

[0017] 2. Vibration reduction: The vibration reduction shrapnel of this product uses a control method to reduce the vibration of the system by consuming vibration energy, that is, using various damping to dissipate the vibration energy of the vibrating body to achieve the purpose of reducing the vibration value.

[0018] 3. Cushioning: This product's cushioning layer reduces the system's response to impact (such as acceleration and relative displacement) to below the permissible limit. The designed cushioning layer should be able to store the energy of the impact, so that the sharp shock wave is applied to the arm in a gentle manner, thereby protecting the arm.

[0023] The present invention is further described in detail below in conjunction with the accompanying drawings, wherein the same parts are represented by the same figure numerals. It should be noted that the words "front", "rear", "left", "right", "up" and "down", "bottom" and "top" used in the following description refer to the directions in the drawings, and the words "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively.

[0024] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0025] Design concept: The designed racket handle is equipped with a sleeve-type hand grip structure, and has the functions of vibration isolation, vibration reduction and buffering.

[0026] Example:

[0027] like Figure 1-Figure 3As shown, the present invention provides a sleeve-type racket comprising a racket body 1, a sleeve 3 encased within a handle 2 of the racket body 1, a cushioning layer 4 between the sleeve 3 and the handle 2, and a vibration-damping spring 5 within the sleeve 3 where it meets the handle 2. The sleeve 3 and the racket body 1 are assembled and fixed together at their ends using fixing pins or other means. Vibration from the racket body 1 is transmitted to the handle 2 and then to the sleeve 3. The cushioning layer 4, made of a material with excellent damping properties, dissipates the energy of the transmitted vibration.

[0028] In this embodiment, an upper cavity 6 and a lower cavity 7 are symmetrically provided in the sleeve body 3, and the cross-sections of the upper cavity 6 and the lower cavity 7 are trapezoidal. The upper cavity 6 and the lower cavity 7 are respectively provided with vibration-damping springs 5 corresponding to the handle 2. After being vibrated, they can store the energy of the impact through their elastic variables, so that the vibration wave is gently applied to the arm, thereby playing a role in protecting the arm, similar to the role of a buffer guardrail on the side of the road.

[0029] In this embodiment, the sleeve body 3 is made of carbon fiber, the buffer layer 4 is made of epoxy resin foam, and the vibration-damping spring 5 is a carbon fiber resin solidified plate or a glass fiber resin solidified plate.

[0030] Working principle and process:

[0031] The sleeve body 3 of this product separates the handle 2 and the racket body 1, which reduces the vibration of the system by controlling the transmission of vibration. An additional subsystem is used to separate the vibration source from the object to be reduced to reduce the impact of the vibration source on the isolation object.

[0032] The vibration damping spring 5 of this product uses a control method to reduce the system vibration by consuming vibration energy, that is, using various damping to dissipate the vibration energy of the vibrating body to achieve the purpose of reducing the vibration value.

[0033] This product's cushioning layer (4) reduces the system's response to impact (such as acceleration and relative displacement) to below acceptable limits. The designed cushioning layer (4) should be able to store the energy of the impact, so that the sharp shock wave is applied to the arm in a gentle manner, thereby protecting the arm.

[0034] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
