Description

Technical Field

[0001] This invention relates to the field of tennis racket technology, specifically to a racket, its manufacturing process, and its applications. Background Technology

[0002] As people's quality of life improves, more and more people choose to exercise in their spare time. However, sports that require physical contact, such as basketball and football, are not friendly to non-sports enthusiasts and are limited by time and venue. As a result, net-hitting ball sports are becoming more and more accepted by people.

[0003] Tennis is a net-based ball sport. Because the tennis ball is relatively heavy, the tennis racket needs to have a certain mass to hit the ball. However, everyone's strength and usage habits are different, so manufacturers cannot customize according to each person's situation. Most people cannot choose a racket that is most comfortable for them, and when some parts of the racket are damaged, the whole racket must be replaced.

[0004] Therefore, a new technical solution is proposed to solve the above problems. Summary of the Invention

[0005] To address the shortcomings of existing technologies, the present invention aims to provide a racket, its manufacturing process, and its application. By detachably connecting the racket body and the racket tube, individual components can be replaced when damaged. Furthermore, the weight of multiple batches of racket bodies and racket tubes can be adjusted, thereby controlling the overall weight and center of gravity of the racket assembled from the two components.

[0006] The above-mentioned technical objective of the present invention is achieved through the following technical solution: a racket, its manufacturing process and its application, comprising a racket body and a racket tube, wherein the racket body and the racket tube are detachably connected by a fixing component, and the racket body and the racket tube are provided with a counterweight component for adjusting their mass and center of gravity.

[0007] By adopting the above technical solution, the racket body can be disassembled using a detachable connection method. The weight of the racket body and the racket tube can be controlled by a counterweight component, thereby controlling the weight of the racket to accommodate players of different strengths. At the same time, the center of gravity of the racket can be controlled by the mass difference between the racket body and the racket tube to accommodate players of different playing styles, thus increasing its applicability.

[0008] The present invention is further configured such that: the fixing component includes a plurality of connecting cylinders fixedly connected to the end face of the paddle tube; the side wall of the connecting cylinder is provided with a plurality of communicating holes; the inner wall of the communicating hole is engaged with an adjusting block; the outer surface of the adjusting block is provided with a locking hole along the direction of the communicating hole; the outer surface of the paddle tube is provided with a plurality of connecting cavities symmetrically distributed along its center line; the connecting cylinder is engaged in the connecting cavity; and the inner wall of the connecting cavity is provided with an adjusting hole communicating with the locking hole; the inner wall of the adjusting hole and the inner wall of the locking hole are engaged with a locking rod; each end of the locking rod is fixedly connected with a locking cylinder; and the locking cylinder is engaged with the inner wall of the opening of the adjusting hole.

[0009] By adopting the above technical solution, using the structure of the connecting cylinder being inserted into the connecting cavity and the structure of the locking rod locking the inner wall of the adjustment hole and the locking hole, the racket body and the racket tube can be detachably connected, which makes it convenient for users to replace damaged parts and reduce maintenance costs.

[0010] The present invention is further configured such that: the fixing component further includes a first locking block and a positioning block fixedly connected to the inner wall of the connecting cavity, the positioning block being engaged with the inner wall of the connecting cylinder, and a second locking block abutting against the positioning block being fixedly connected to the outer surface of the connecting cylinder.

[0011] By adopting the above technical solution, the position of the end point of the connecting tube is positioned by the positioning block engaging with the inner wall of the connecting tube, thereby increasing the connection strength between the racket body and the racket tube. Furthermore, the structure of the second locking block abutting against the positioning block prevents internal stress when the racket body and the racket tube are connected, reduces the generation of torque, and increases the installation accuracy and service life of the racket.

[0012] The present invention is further configured such that: the counterweight component includes a first counterweight assembly disposed on the racket body and a second counterweight assembly disposed on the racket tube, and the center of gravity position is controlled by controlling the weight of the first counterweight assembly and the second counterweight assembly.

[0013] By adopting the above technical solution, the weight of the racket can be controlled by the first and second counterweight components, making it convenient for people of different strengths to use, while also controlling the center of gravity of the racket.

[0014] The present invention is further configured such that: the first counterweight assembly includes a counterweight block fixedly connected to the inner wall of the first counterweight cavity, and a blocking block is engaged on the outer surface of the beater to block the opening of the first counterweight cavity, and the blocking block abuts against one end of the counterweight block.

[0015] By adopting the above technical solution, the weight of the racket body is adjusted by using counterweights of different masses. At the same time, the counterweights are stuck in the first counterweight cavity by using a plug. The friction between the plug and the racket body surface is increased by wrapping the plug with adhesive tape, thereby increasing the installation strength.

[0016] The present invention is further configured such that: the second counterweight assembly includes a counterweight cylinder, and a second counterweight cavity is provided on both sides of the inner cavity of the tapping tube, and the counterweight cylinder is fixedly connected to the inner wall of the second counterweight cavity.

[0017] By adopting the above technical solution, the hollow structure of the second counterweight cavity is utilized and sponges of different densities are introduced into it, making it convenient for users to control the quality of the beat tube.

[0018] The present invention is further configured such that the connecting hole is elongated along the direction of the tapping tube and forms a rounded matrix shape.

[0019] By adopting the above technical solution, after weight adjustment, the control blocks with different positions of locking hole and control block edge are inserted into the connecting hole. The position of locking hole relative to control block controls the depth of connecting cylinder inserted into connecting cavity, thereby further adjusting the center of gravity.

[0020] The present invention is further configured such that: the length of the first card block is greater than the length of the second card block and less than the depth of the connecting cavity, and the first card block is fixedly connected to the bottom wall of the connecting cavity.

[0021] By adopting the above technical solution, and utilizing the structural arrangement of the first card block, the second card block, and the connecting cavity, the second card block can abut against and be positioned with the first card block when it is inserted into the connecting cavity and fixed, while ensuring that the second card block does not protrude outside the connecting cavity to enhance aesthetics.

[0022] The invention is further configured as follows: Step 1, casting the racket body using a mold; Step 2, inserting the counterweight cylinder into the second counterweight cavity and controlling the weight of the racket tube; Step 3, positioning the racket tube using the connecting cylinders at both ends of the racket tube, and then bending the racket tube and the counterweight cylinder together; Step 4, inserting a counterweight block of appropriate weight into the first counterweight cavity and blocking the lower opening of the racket body using a plug; Step 5, inserting the adjusting block, with the locking hole at an appropriate distance from the edge of the adjusting block, into the connecting hole; Step 6, pouring glue into the connecting cavity, inserting the connecting cylinders at both ends of the racket tube into the connecting cavity, and using a locking rod passing through the adjusting hole and the connecting hole to complete the fixation of the racket body and the racket tube.

[0023] By adopting the above technical solution, the production technology can be used to complete the manufacturing of tennis rackets, reducing the production steps and saving costs. At the same time, it can separate the production steps from the assembly steps, reduce the factory floor space, and increase production efficiency.

[0024] The present invention is further configured as follows: racket bodies of different materials are prepared by using a mold, and the racket tube and racket body are detachably connected as one unit. At the same time, the weight is adjusted by a counterweight component. The counterweight component includes a second counterweight cavity and a counterweight block. When the racket body and racket tube are disassembled and separated, sponge blocks of different masses are inserted into the second counterweight cavity, and counterweight blocks of different masses are inserted into the first counterweight cavity to complete the weight control. The center of gravity position is then controlled by the density difference between the racket body and the racket tube.

[0025] By adopting the above technical solutions, users can adjust the racket's quality and center of gravity according to their own conditions, increasing the racket's applicability and practicality.

[0026] In summary, the present invention has the following beneficial effects:

[0027] First, the racket's detachable design of the racket body and tube allows for the replacement of damaged parts, reducing maintenance costs.

[0028] Secondly, before use, users can separate the racket body and the racket tube and adjust their weights using the counterweight components to adapt to the strength of different users, increasing the racket's applicability. At the same time, the center of gravity can be adjusted according to the weight of the racket body and the racket tube to suit the playing style of different users.

[0029] Third, the racket body and shaft can be produced first, and then racket bodies and shafts of different qualities can be assembled according to the order requirements to suit people with different strengths and playing styles. This prevents the production of too many rackets of the same type at one time, which would lead to unsold goods and reduce production costs.

[0030] Fourth, by using control blocks of different specifications, the center of gravity of the racket can be adjusted during production assembly and user self-adjustment, reducing the scrap rate of the racket and increasing its applicability. Attached Figure Description

The fixing component also includes a first locking block 19 and a positioning block 18 fixedly connected to the inner wall of the connecting cavity 20. The positioning block 18 is engaged with the inner wall of the connecting cylinder 13. A second locking block 16 is fixedly connected to the outer surface of the connecting cylinder 13 and abuts against the positioning block 18.

[0046] like Figure 2 , Figure 5 and Figure 9 As shown, the counterweight component includes a first counterweight assembly disposed on the racket body 11 and a second counterweight assembly disposed on the racket tube 12. The center of gravity position is controlled by controlling the weight of the first and second counterweight assemblies. The first counterweight assembly includes a counterweight block 28 fixedly connected to the inner wall of the first counterweight cavity 21. A blocking block 17 is snapped onto the outer surface of the racket body 11 to block the opening of the first counterweight cavity 21, and the blocking block 17 abuts against one end of the counterweight block 28. The second counterweight assembly includes a counterweight cylinder 26. Second counterweight cavities 27 are also disposed on both sides of the inner cavity of the racket tube 12. The counterweight cylinder 26 is fixedly connected to the inner wall of the second counterweight cavity 27.

[0047] like Figure 3 As shown, the connecting hole 15 is elongated along the direction of the drum tube 12 and has a rounded corner matrix shape.

[0048] like Figure 2 and Figure 4 As shown, the length of the first card block 19 is greater than the length of the second card block 16 and less than the depth of the connecting cavity 20, and the first card block 19 is fixedly connected to the bottom wall of the connecting cavity 20.

[0049] like Figures 1 to 9As shown, in step one, the racket body 11 is cast using a mold; in step two, the counterweight cylinder 26 is inserted into the second counterweight cavity 27 and the weight of the racket tube 12 is controlled; in step three, the racket tube 12 is positioned using the connecting cylinders 13 at both ends of the racket tube 12, and then the racket tube 12 and the counterweight cylinder 26 are bent together; in step four, a counterweight block 28 of appropriate weight is inserted into the first counterweight cavity 21 and the lower opening of the racket body 11 is blocked using the plug 17; in step five, the adjusting block 22, which is at an appropriate distance from the edge of the adjusting block 22, is inserted into the connecting hole 15; in step six, glue is poured into the connecting cavity 20, the connecting cylinders 13 at both ends of the racket tube 12 are inserted into the connecting cavity 20, and the locking rod 24 is passed through the adjusting hole 14 and the connecting hole 15 to complete the fixation of the racket body 11 and the racket tube 12.

Then, the adjusting block 22 is inserted into the connecting hole 15. The distance between the locking hole 23 on different adjusting blocks 22 and its edge is used to control the depth of the connecting tube 13 inserted into the connecting cavity 20, thereby adjusting the racket's center of gravity. Finally, the connecting tubes 13 at both ends of the racket tube 12 are inserted into the connecting cavity 20, causing the positioning block 18 to engage with the connecting tube 13. The inner cavity is used to position the two ends of the racket tube 12. Then, the second locking block 16 is slid into the connecting cavity 20 and abuts against the first locking block 19 to prevent torque from being generated during the installation of the racket tube 12. Then, the locking rod 24 is inserted into the adjusting hole 14 and the locking hole 23. The connecting cylinder 13 is fixed to the inner wall of the connecting cavity 20 by the abutment between the locking rod 24 and the inner wall of the adjusting hole 14, achieving initial locking. Then, the weight and center of gravity of the racket are checked. If they are not up to standard, the locking rod 24 is pulled out and the weight is adjusted again. If they are up to standard, the locking rod 24 is pulled out and filling is added to the connecting cavity 20. Fill with water and insert the locking rod 24 into the connecting cavity 20. Secure the two locking cylinders 25 at the two ends of the locking rod 24, and simultaneously engage the outer wall of the locking cylinder 25 with the inner wall of the regulating hole 14 to lock the racket body 11 and the racket tube 12. Then, place the plug 17 into the opening of the first counterweight cavity 21 and secure the inner wall of the plug 17 with the outer surface of the racket body 11. Use adhesive tape to bind the plug 17 and increase the friction between the plug 17 and the racket body 11. Use the plug 17 to block the opening of the first counterweight cavity 21 and prevent the counterweight 28 from falling out.

[0051] Example 2:

[0052] This type of racket, its manufacturing process, and its applications, such as Figures 1 to 4 As shown, it includes a racket body 11 and a racket tube 12.

[0053] like Figure 3 , Figure 4 , Figure 6 , Figure 7 and Figure 8 As shown, the fixing component includes several connecting cylinders 13 fixedly connected to the end face of the racket tube 12. Several communicating holes 15 are provided through the sidewalls of the connecting cylinders 13. Adjusting blocks 22 are engaged with the inner walls of the communicating holes 15.

A blocking block 17 is snapped onto the outer surface of the racket body 11 to block the opening of the first counterweight cavity 21, and the blocking block 17 abuts against one end of the counterweight block 28. The second counterweight assembly includes a counterweight cylinder 26. Second counterweight cavities 27 are also disposed on both sides of the inner cavity of the racket tube 12.

[0055] like Figure 3 As shown, the connecting hole 15 is elongated along the direction of the drum tube 12 and has a rounded corner matrix shape.

[0056] like Figure 2 and Figure 4As shown, the length of the first card block 19 is greater than the length of the second card block 16 and less than the depth of the connecting cavity 20, and the first card block 19 is fixedly connected to the bottom wall of the connecting cavity 20.

[0057] like Figures 1 to 9 As shown, in step one, the racket body 11 is cast using a mold; in step two, the counterweight cylinder 26 is inserted into the second counterweight cavity 27 and the weight of the racket tube 12 is controlled; in step three, the racket tube 12 is positioned using the connecting cylinders 13 at both ends of the racket tube 12, and then the racket tube 12 and the counterweight cylinder 26 are bent together; in step four, a counterweight block 28 of appropriate weight is inserted into the first counterweight cavity 21 and the lower opening of the racket body 11 is blocked using the plug 17; in step five, the regulating block 22, which is at an appropriate distance from the edge of the regulating block 22, is inserted into the connecting hole 15; in step six, the connecting cylinders 13 at both ends of the racket tube 12 are inserted into the connecting cavity 20, and the locking rod 24 is passed through the regulating hole 14 and the connecting hole 15 to complete the fixation of the racket body 11 and the racket tube 12.

[0058] like Figures 1 to 9 As shown, racket bodies 11 of different materials are prepared using molds, and racket tubes 12 are detachably connected to racket bodies 11 as a whole. At the same time, weight is adjusted by a counterweight component, which includes a second counterweight cavity 27 and a counterweight block 28. When racket bodies 11 and racket tubes 12 are disassembled and separated, sponge blocks of different masses are inserted into the second counterweight cavity 27, and counterweight blocks 28 of different masses are inserted into the first counterweight cavity 21 to complete weight control. The center of gravity position is then controlled by the density difference between racket bodies 11 and racket tubes 12.

[0059] First, the racket body 11 is cast using aluminum alloy, carbon alloy, and iron alloy. The weight of the racket body 11 is controlled by the density of different alloys. Then, the counterweight cylinder 26 is inserted into the second counterweight cavity 27, and the racket tube 12 is integrated with the counterweight cylinder 26. The racket tube 12 is positioned using the second locking blocks 16 on the connecting cylinders 13 at both ends. Then, the racket tube 12 and the counterweight cylinder 26 are bent into shape. Then, according to the user's power parameters and the wind of the game, sponges of different densities are pushed into the second counterweight cavity 27, and counterweight blocks 28 of different masses are inserted into the first counterweight cavity 21, thereby controlling the racket body 11 and the racket tube 16. The weight of the racket is controlled by adjusting the weight of the racket body 11 and the racket tube 12. The different weights of the racket body 11 and the racket tube 12 allow for control of the racket's center of gravity, facilitating use. The adjusting block 22 is then inserted into the connecting hole 15. The distance between the locking hole 23 on the adjusting block 22 and its edge is used to control the depth of the connecting tube 13 inserted into the connecting cavity 20, thus adjusting the racket's center of gravity. The connecting tubes 13 at both ends of the racket tube 12 are then inserted into the connecting cavity 20, causing the positioning block 18 to engage with the inner cavity of the connecting tube 13, completing the positioning of both ends of the racket tube 12. Finally, the second locking block 16 is slid into the connecting cavity 20 and engages with the first... A locking block 19 abuts against the racket tube 12 to prevent torque from being generated during installation. Then, the locking rod 24 is inserted into the adjustment hole 14 and the locking hole 23. The connecting cylinder 13 is fixed to the inner wall of the connecting cavity 20 by the abutment between the locking rod 24 and the inner wall of the adjustment hole 14, achieving initial locking. Then, the weight and center of gravity of the racket are checked. If they are not up to standard, the locking rod 24 is pulled out and the weight is adjusted again. If they are up to standard, the two locking cylinders 25 are respectively locked at the two ends of the locking rod 24. At the same time, the outer wall of the locking cylinder 25 is locked with the inner wall of the adjustment hole 14, completing the locking of the racket body 11 and the racket tube 12. Then, the plug 17 is put on. The first counterweight cavity 21 is opened, and the inner wall of the plug 17 is locked to the outer surface of the racket body 11. Then, the plug 17 is tied in with glue to increase the friction between the plug 17 and the racket body 11. The plug 17 blocks the opening of the first counterweight cavity 21 and prevents the counterweight 28 from falling out. When the user needs to replace the racket body 11 or the racket tube 12, or adjust the weight, the locking rod 24 is pushed out to complete the disassembly of the racket body 11 and the racket tube 12. The plastic rod is inserted into the second counterweight cavity 27 or the counterweight cylinder 26 is pulled out. Then the plug 17 is removed and the counterweight 28 is replaced, which increases the practicality.
