Description

Technical Field

[0001] This utility model relates to the field of racket technology, specifically to a carbon fiber tennis racket frame structure. Background Technology

[0002] Carbon fiber tennis racket frame structures commonly come in elliptical and near-circular shapes, as well as innovative designs such as square and hexagonal. Traditional round frames allow for even power distribution and smooth power transfer during shots. They are mainly made of carbon fiber, while some high-end rackets use more advanced materials such as nano-ultra-rigid carbon fiber. Carbon fiber has the characteristics of high strength and low weight, providing good control and faster swing speed, and its strength is sufficient to withstand high-intensity impact forces.

[0003] The existing carbon fiber tennis racket frame structure still has the following problems when used: The raw material cost of carbon fiber tennis rackets is relatively high. Because its existing frame structure usually adopts a fully enclosed one-piece frame design, it requires more carbon fiber raw materials, which makes its price much more expensive than tennis rackets made of other materials. In addition, although the overall carbon fiber material has high structural strength, it is brittle. It is prone to cracking when frequently and forcefully swung or subjected to large high-frequency impact vibrations. Some tiny cracks may not be easily detected, and continued use will lead to accelerated damage. Utility Model Content

[0024] Please see Figures 1-4In this embodiment of the utility model, a carbon fiber tennis racket frame structure includes a frame body 1, which is made of carbon fiber. The frame body 1 includes an outer frame 11, and an inner frame 16 is fixedly connected between the inner sidewalls at both ends of the upper part of the outer frame 11. A first groove 12 matching the outline of the outer frame 11 is opened at the middle position of the outer surface of the outer frame 11, and a second groove 17 is opened at the middle position of the top of the inner frame 16. It adopts a combined frame structure design, which includes an outer frame 11 and an inner frame 16, both of which are made of carbon fiber. However, the outer frame 11 has a first groove 12 matching the outline of the outer frame 11 at the middle position, and the inner frame 16 has a second groove 17 at the middle position of the top of the inner frame 16. Compared with a fully integrated closed frame structure, it requires less carbon fiber material, resulting in a lower overall cost and a significant price reduction.

[0025] The outer frame 11 and the inner frame 16 are coated with a ceramic coating. Multiple aluminum alloy reinforcing blocks 4 are fixedly connected at equal intervals to the two ends of the first groove 12, matching the outline of the outer frame 11. An aluminum alloy reinforcing seat 5 matching the outline of the outer frame 11 is also fixedly connected to the bottom of the first groove 12. A protective coating is added to the surface of the outer frame 11 and the inner frame 16 of the racket frame. This coating is a ceramic coating with high wear resistance and impact resistance, which enhances the surface strength of the racket frame. At the same time, the multiple aluminum alloy reinforcing blocks 4 are fixedly connected at equal intervals to the two ends of the first groove 12, matching the outline of the outer frame 11, and the aluminum alloy reinforcing seat 5 matching the outline of the outer frame 11 is also fixedly connected to the bottom of the first groove 12. This reduces the possibility of damage to the racket frame when it is frequently and forcefully swung or subjected to large high-frequency impact vibrations.

[0026] Multiple first tennis racket strings 13 are installed in a top-to-bottom equidistant manner inside the racket frame 1, and multiple second tennis racket strings 14 are installed in a horizontally equidistant manner inside the racket frame 1. The multiple first tennis racket strings 13 and multiple second tennis racket strings 14 are arranged in an alternating manner. The first groove 12 has first through slots at both ends for assembling the first tennis racket strings 13, and the bottom ends of the first groove 12 and the second groove 17 have second through slots for assembling the second tennis racket strings 14. The tennis racket strings play the role of providing elasticity, cushioning and shock absorption, and controlling the direction and spin of the ball during tennis.

[0027] The top of the outer frame 11 is fixedly connected to the mounting mechanism 3. The mounting mechanism 3 includes a connecting seat 31 fixedly connected to the top of the outer frame 11. A mating assembly seat 32 is fixedly connected to the middle of the top of the connecting seat 31. A connecting bolt 33 is fixedly connected to the center of the top of the mating assembly seat 32. The overall frame structure can be fitted with the tennis racket grip structure through its connecting bolt 33.

[0028] An auxiliary reinforcement mechanism 2 is provided between the bottom end of the connecting seat 31 and the top end of the inner frame 16. The auxiliary reinforcement mechanism 2 includes two sets of first reinforcement beams 21 that are symmetrically fixedly connected between the bottom end of the connecting seat 31 and the top end of the inner frame 16. Each set of first reinforcement beams 21 consists of two beams that are symmetrically arranged. The same second reinforcement beam 22 is fixedly connected between the four first reinforcement beams 21, which plays an auxiliary reinforcement role in the overall frame structure.

[0029] Multiple pressure relief holes 15 are equidistantly provided at the bottom of the inner frame 11. Matching holes 6 are provided between the outer walls of the upper and lower ends of the aluminum alloy reinforcing seat 5 to facilitate the flow and pressure relief of gas within the frame 1.

[0030] The working principle of this utility model is as follows: The overall frame structure can be fitted with the tennis racket grip structure through its connecting bolts 33. At the same time, a protective coating is added to the surface of the outer frame 11 and the inner frame 16 of the frame. This coating is a ceramic coating with high wear resistance and impact resistance, which enhances the surface strength of the frame. In addition, multiple aluminum alloy reinforcing blocks 4 are fixedly connected at equal intervals to the two ends of the first groove 12, matching the contour of the outer frame 11. An aluminum alloy reinforcing seat 5 matching the contour of the outer frame 11 is also fixedly connected to the bottom end of the first groove 12. Under frequent and forceful swings or large high-frequency impact vibrations, the possibility of damage to the frame can be reduced. The tennis racket strings play a role in providing elasticity, buffering and shock absorption, and controlling the direction and spin of the ball during tennis. In addition, the overall frame structure is provided with an auxiliary reinforcement mechanism 2, which plays an auxiliary reinforcement role in the overall frame structure.
