Description

Technical Field

[0001] This utility model relates to the field of sports equipment technology, and in particular to a badminton racket. Background Technology

[0002] Badminton, an indoor sport that combines competition and entertainment, is played by two players using rackets to hit a shuttlecock over a net on a designated rectangular court, aiming to land the shuttlecock in the opponent's court. The rules require players to precisely control the power, angle, and landing point of their shots. The shaft of the badminton racket, as a key component for transmitting the power of the shot, needs to have good elasticity and strength. The grip is the part that directly contacts the player and the racket, and its stability and comfort are crucial. The stability of the connection between the two is also related to the accuracy of the player's control at the moment of impact.

[0003] Currently, most badminton rackets on the market use glue to connect the shaft and grip. This method involves applying a special glue to the contact surfaces of the shaft and grip, and then using the adhesive effect after the glue cures to connect the two as one unit. This prevents relative displacement between the shaft and grip during use and meets the basic needs of daily training and ordinary competitions.

[0004] However, under high-intensity professional competition or long-term use scenarios, the drawbacks of this type of connection gradually become apparent: after prolonged use, the glue will age and lose its stickiness due to repeated impact and torque generated by the ball. At the same time, since it is difficult to ensure the uniformity of glue application, it will lead to uneven stress on the connection parts and insufficient bonding strength in some areas. When the athlete makes a powerful smash or fast drive, the connection between the shaft and the grip needs to bear greater stress. The glue fixing method cannot provide sufficient mechanical restraint, causing the connection to loosen, which in turn affects the accuracy and stability of power transmission when hitting the ball. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a badminton racket that aims to improve the existing technology. After long-term use, the racket will age and lose its adhesiveness due to repeated impact and torque from hitting the shuttlecock. At the same time, the unevenness of the glue application is difficult to guarantee, which will cause uneven stress on the connection parts and make it difficult to guarantee the landing point at the moment of hitting the shuttlecock.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a badminton racket, including a shaft, a frame fixedly connected to the top of the shaft, and a wooden handle fixedly connected to the bottom of the shaft via a fixing mechanism. The fixing mechanism is used to fix the shaft and the wooden handle. A conical cap mechanism is provided on the top outer side of the wooden handle. The conical cap mechanism is used to more securely combine the badminton racket handle and the badminton shaft. A racket string is provided inside the frame. The conical cover mechanism includes an outer cover, on the front and back sides of the top of the outer cover, V-shaped grooves are provided, and an inner cover is fixedly connected inside the outer cover. The inner cover has U-shaped grooves on the front and back sides of the top of the inner cover and is engaged with the top of the wooden handle.

[0007] As a further description of the above technical solution: The fixing mechanism includes a tapered hole, which is located in the upper middle part of the front side of the wooden handle. A threaded hole is located in the lower middle part of the front side of the central rod. A fixing screw passes through the tapered hole, and the end of the fixing screw is threaded into the inside of the threaded hole.

[0008] As a further description of the above technical solution: Multiple cable guards are fixedly connected to the inner side of the racket frame, and each cable guard is sleeved on the outside of the racket rope.

[0009] As a further description of the above technical solution: The wooden handle is fixedly connected to an anti-slip base, and the exterior of the anti-slip base is finished with a frosted process.

[0010] As a further description of the above technical solution: The bottom of the wooden handle is fitted with an end plug, and the bottom end of the end plug is provided with a bottom cover sleeve, the bottom end of the end plug being fitted inside the bottom cover sleeve.

[0011] As a further description of the above technical solution: A retaining pin extends through the front side of the bottom cover sleeve, and the rear end of the retaining pin extends through the interior of the end plug.

[0012] As a further description of the above technical solution: The bottom end of the bottom cover sleeve is fitted with a bottom modification insert, and the outside of the bottom modification insert is designed with chamfers.

[0013] As a further description of the above technical solution: The wooden handle has a hexagonal shape, and the bottom of the wooden handle has a hexagonal pyramidal shape.

[0014] This utility model has the following beneficial effects: 1. In this utility model, the V-shaped groove of the outer cover is adapted to the hand grip angle, and the U-shaped groove of the inner cover is tightly engaged with the hexagonal top of the wooden handle. The double-layer structure of the outer and inner covers works together with the special shape of the wooden handle and the fixing mechanism to achieve a stable connection of the components. This improves the stability of the connection between the racket handle and the shaft in badminton, reduces grip slippage, evenly transmits the hitting force, and enhances the athlete's accuracy in controlling the ball and the durability of the racket at the moment of hitting.

[0015] 2. In this utility model, the conical hole and the threaded hole are aligned on the axis, and the fixing screw passes through both and is threaded together. When tightened, the screw head presses against the conical surface of the conical hole, causing the wooden handle material to be compressed to form an interference fit. At the same time, an axial tensile force is generated to tighten the shaft and the wooden handle. This ensures a stable connection between the shaft and the wooden handle during badminton, disperses the impact force and torque of the shot, prevents the connection from loosening, and improves the reliability of the racket and the control of the shot.

Detailed Implementation

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 2 and Figure 3The present invention provides an embodiment of a badminton racket, including a shaft 1, a frame 2 fixedly connected to the top of the shaft 1, and a wooden handle 3 fixedly connected to the bottom of the shaft 1 through a fixing mechanism 6. The wooden handle 3 has a hexagonal shape and a hexagonal pyramidal shape at the bottom. The fixing mechanism 6 is used to fix the shaft 1 and the wooden handle 3. A cone-shaped cover mechanism 4 is provided on the top of the outer side of the wooden handle 3. The cone-shaped cover mechanism 4 is used to more firmly connect the badminton racket handle and the badminton shaft. A racket string 5 is provided inside the frame 2. The cone cover mechanism 4 includes an outer cover 41, with V-shaped grooves 42 on both the front and rear sides of the top of the outer cover 41. An inner cover 43 is fixedly connected inside the outer cover 41, with U-shaped grooves 44 on both the front and rear sides of the top of the inner cover 43. The inner cover 43 is engaged with the top of the wooden handle 3. Specifically, the cone-shaped cover mechanism 4 achieves a stable connection between the badminton racket handle and the shaft 1 through the coordinated operation of the outer cover 41, V-shaped groove 42, inner cover 43, and U-shaped groove 44. The outer cover 41 is made of high-strength engineering plastic, which has good wear resistance and impact resistance. The V-shaped groove 42 on the front and back sides of its top is used to adapt to the grip angle of the hand when hitting the racket, reducing the sliding friction between the hand and the cone cover. The inner cover 43, which is fixedly connected inside the outer cover 41, is made of polycarbonate material, which has high toughness and rigidity and can disperse stress at the moment of impact. The U-shaped grooves 44 on the front and back sides of the top of the wooden handle 3 correspond to the hexagonal structure on the top of the handle 3. During installation, the inner cover 43 is snapped onto the top of the handle 3. The groove wall of the U-shaped groove 44 fits tightly against the hexagonal side of the handle 3, forming a mechanical limiting structure that restricts the rotation and displacement of the inner cover 43 relative to the handle 3. The double-layer structure design of the outer cover 41 and the inner cover 43 enhances the overall structural strength of the cone cover mechanism 4. The outer cover 41 provides external protection and grip fit, while the inner cover 43 achieves precise snap-fit ​​fixation with the handle 3. During badminton, when the athlete swings the racket to hit the shuttlecock... The impact force and torque generated during the stroke are relatively large. At this time, the inner cover 43 of the cone cover mechanism 4 is tightly engaged with the wooden handle 3 through the U-shaped groove 44, which evenly transmits the hitting force to the center shaft 1 and avoids local stress concentration. The V-shaped groove 42 of the outer cover 41 helps the hand to hold the ball stably and ensures the accuracy of the force direction. At the same time, the high-strength material of the outer cover 41 and inner cover 43 can effectively resist wear and deformation during long-term use and frequent hitting, and maintain the stability of the connection between the handle and the center shaft 1. The wooden handle 3 adopts a hexagonal and hexagonal pyramidal design. The hexagonal shape increases the contact with the hand. Friction facilitates grip; the hexagonal pyramidal bottom design ensures a stable connection between the wooden handle 3 and the fixing mechanism 6. The fixing mechanism 6 securely fixes the shaft 1 to the wooden handle 3. The racket string 5 inside the frame 2 is used to suspend the racket or connect the wrist, preventing the racket from slipping out of the hand. It is fixed by the double-layer structure of the cone-shaped cover mechanism 4. Combined with the special shape design of the wooden handle 3, the connection of the fixing mechanism 6, and the assistance of the racket string 5, the connection between the racket handle and the shaft 1 is strengthened in badminton scenarios, enhancing the athlete's accuracy in controlling the ball at the moment of impact.

[0020] Reference Figure 5 The fixing mechanism 6 includes a tapered hole 61, which is located in the upper middle part of the front side of the wooden handle 3. A threaded hole 62 is located in the lower middle part of the front side of the central rod 1. A fixing screw 63 passes through the tapered hole 61, and the end of the fixing screw 63 is threaded into the inside of the threaded hole 62. Specifically, a tapered hole 61 is opened in the upper-middle part of the front side of the wooden handle 3, and its diameter gradually decreases from the surface of the wooden handle 3 inward to form a tapered structure; a threaded hole 62 is opened in the lower-middle part of the front side of the middle rod 1, and its axis is aligned with the axis of the tapered hole 61. The internal thread engages with the external thread of the fixing screw 63. The fixing screw 63 passes through the tapered hole 61, and its end is threaded into the inside of the threaded hole 62. When the fixing screw 63 is tightened, the screw head contacts the tapered surface of the tapered hole 61, generating radial pressure, which causes the material around the tapered hole 61 of the wooden handle 3 to be squeezed towards the middle rod 1, forming an interference fit and enhancing the tightness of the connection. At the same time, the axial tensile force generated by the threaded connection pulls the middle rod 1 and the wooden handle 3 together along the axial direction, further improving the fixing effect. The outer cover 41 of the tapered cover mechanism 4 is made of high-strength engineering plastic and has the following properties: With excellent wear resistance and impact resistance, the inner cover 43 is made of polycarbonate material, which has high toughness and rigidity. The double-layer structure formed by the two can disperse the impact force and torque generated during the shot after the fixing mechanism 6 connects the shaft 1 and the wooden handle 3, preventing the connection from loosening due to concentrated force. The hexagonal shape of the wooden handle 3 increases the grip friction. When the hexagonal cone bottom end cooperates with the fixing mechanism 6, it can help to position the installation angle of the shaft 1. The racket rope 5 inside the frame 2 is used to hang the racket or connect the wrist to prevent the racket from slipping out of the hand during the game. Through the threaded connection of the fixing screw 63 in the conical hole 61 and the threaded hole 62 and the conical surface compression, combined with the structural reinforcement of the cone cover mechanism 4, the connection between the shaft 1 and the wooden handle 3 is ensured to be stable in badminton games, improving the reliability of racket use and the control of the shot.

[0021] Reference Figure 3 and Figure 4 Multiple cable sheaths 7 are fixedly connected to the inner side of the frame 2, and the multiple cable sheaths 7 are respectively sleeved on the outside of the string 5; the outside of the wooden handle 3 is fixedly connected to the anti-slip base 8, and the outside of the anti-slip base 8 is frosted; the bottom of the wooden handle 3 is fitted with an end plug 9, and the bottom end of the end plug 9 is provided with a bottom cover sleeve 10, and the bottom end of the end plug 9 is fitted inside the bottom cover sleeve 10; a fixing pin 11 passes through the front side of the bottom cover sleeve 10, and the rear end of the fixing pin 11 passes through the inside of the end plug 9; the bottom end of the bottom cover sleeve 10 is fitted with a bottom modification insert 12, and the outside of the bottom modification insert 12 is chamfered. Specifically, the multiple grommets 7 fixed inside the frame 2 are made of high-strength nylon, which is wear-resistant and cut-resistant. These grommets 7 are fitted over the string 5. When the shuttlecock hits the frame 2, the grommets 7 isolate the string 5 from direct contact with the frame 2, reducing wear on the string 5 under friction and extending its lifespan. Simultaneously, their smooth inner walls reduce the resistance of the string 5, ensuring stable racket tension during impact. The anti-slip base 8 on the outside of the handle 3 is made of thermoplastic elastomer (TPE) material, with a frosted surface forming micro-protrusions. When the anti-slip base 8 comes into contact with the skin, the protrusions increase the roughness of the contact surface, increasing friction and preventing the racket from slipping during grip. The elastic properties of the TPE material absorb vibrations during hand movements, improving grip comfort and stability. The end caps 9 at the bottom of the handle 3 are made of hard rubber, providing good cushioning and shock absorption. Yes, the end plug 9 is engaged with the bottom of the wooden handle 3, which can seal the internal space of the wooden handle 3 to prevent moisture and dust from entering; its bottom end is engaged with the inside of the bottom cover sleeve 10 to form a positioning fit. The bottom cover sleeve 10 is made of aluminum alloy, and the fixing pin 11 that runs through the front is made of stainless steel. The rear end of the fixing pin 11 is inserted into the end plug 9. Through interference fit and mechanical limit, the end plug 9 and the bottom cover sleeve 10 are firmly connected to prevent the parts from loosening during movement. The bottom modification insert 12 engaged with the bottom end of the bottom cover sleeve 10 is made of polyoxymethylene (POM) material. Its external chamfer design can reduce the scratches of the edge corners on the user, and at the same time facilitate installation and disassembly. The bottom modification insert 12 and the bottom cover sleeve 10 cooperate to further enhance the structural strength of the end of the handle, distribute the stress on the bottom of the handle when hitting the ball, and achieve the effect of extending the service life of the racket and improving the grip comfort and control of the shot in badminton.

[0022] Working Principle: The badminton racket uses the shaft 1 as its core load-bearing component. Its top end is fixedly connected to the frame 2, and its bottom end is connected to the handle 3 via a fixing mechanism 6. The shaft 1, acting as a bridge between the frame 2 and the handle 3, needs to possess high strength and toughness to transmit hitting power. The handle 3 adopts a hexagonal shape and a hexagonal conical bottom design. The former increases the contact friction with the hand, making it easier to grip; the latter, when used with the fixing mechanism 6, can accurately position and form a stable connection structure. The frame 2 has a racket string 5 inside, used to hang the racket or connect the wrist, preventing the racket from slipping out of the hand during movement and laying the foundation for the coordinated work of subsequent components. The fixing mechanism 6 uses a conical hole 61 and a threaded hole 6... 2. The fixing screw 63 securely fixes the middle rod 1 to the wooden handle 3. During assembly, the tapered hole 61 on the upper front side of the wooden handle 3 is first aligned with the threaded hole 62 on the lower front side of the middle rod 1. The tapered hole 61 has a tapered structure that gradually narrows from the surface of the wooden handle 3 inwards. The threaded hole 62 has an internal thread that matches the fixing screw 63. Then, the fixing screw 63 is passed through the tapered hole 61 and its end is screwed into the threaded hole 62. As the fixing screw 63 is tightened, the screw head contacts the tapered surface of the tapered hole 61, applying radial pressure to the material around the tapered hole 61 of the wooden handle 3, causing the material to be squeezed towards the middle rod 1, forming an interference fit. The threaded connection significantly enhances the tightness of the connection. Simultaneously, the axial tension generated by the threaded connection pulls the shaft 1 and the handle 3 along the axial direction, further improving the fixation effect and ensuring that there is no relative displacement between the two during the shot. The cone-shaped cover mechanism 4 consists of an outer cover 41, a V-shaped groove 42, an inner cover 43, and a U-shaped groove 44, used to further stabilize the connection between the badminton racket handle and the shaft 1. During installation, the inner cover 43 is first snapped onto the top of the handle 3. The inner cover 43 is made of polycarbonate, possessing high toughness and rigidity. The U-shaped grooves 44 on its front and rear sides precisely correspond to the hexagonal structure on the top of the handle 3, and the groove walls of the U-shaped groove 44 fit tightly against the hexagonal sides of the handle 3. This forms a mechanical limiting structure, effectively restricting the rotation and displacement of the inner cover 43 relative to the wooden handle 3. After the inner cover 43 is installed in place, the outer cover 41 is fixed to the outside of the inner cover 43. The outer cover 41 is made of high-strength engineering plastic, which has good wear resistance and impact resistance. The V-shaped grooves 42 on the front and back sides of its top can adapt to the angle of force when the athlete holds the racket, reducing the sliding friction between the hand and the cone cover. The double-layer structure design of the outer cover 41 and the inner cover 43 enables the cone cover mechanism 4 to disperse the impact force and torque at the moment of impact. The inner cover 43 is tightly engaged with the wooden handle 3 through the U-shaped groove 44, which evenly transmits the impact force to the middle shaft 1, avoiding local stress concentration.The V-shaped groove 42 of the outer cover 41 assists in a stable grip and ensures the accuracy of the force direction. Multiple string protectors 7, fixedly connected to the inner side of the frame 2, are made of high-strength nylon, possessing wear-resistant and cut-resistant properties. These string protectors 7 are fitted over the string 5. When the shuttlecock impacts the frame 2, the string protectors 7 act as a buffer and isolation component. On one hand, they prevent direct contact between the string 5 and the frame 2, reducing wear on the string 5 under friction and effectively extending its lifespan. On the other hand, the smooth inner wall of the string protectors 7 reduces the resistance of the string 5 during movement, ensuring a smooth and accurate hit. The stable racket face tension improves the accuracy and power transfer efficiency of the shot. The anti-slip sole 8 on the outside of the wooden handle 3 is made of thermoplastic elastomer (TPE) material. After being treated with a frosting process, a micro-protruding structure is formed on the surface. When the athlete holds the racket, the protruding structure of the anti-slip sole 8 comes into contact with the skin of the hand, increasing the roughness of the contact surface and greatly increasing the friction, preventing the racket from slipping when gripping. At the same time, the elastic properties of the TPE material can absorb the vibration generated when the hand exerts force, reducing hand fatigue and improving grip comfort and stability. The end plug 9 at the bottom of the wooden handle 3... Made of hard rubber, it has good cushioning and shock absorption performance. The end plug 9 is engaged with the bottom of the wooden handle 3, sealing the internal space of the wooden handle 3, effectively preventing moisture and dust from entering and protecting the internal structure of the wooden handle 3. The bottom end of the end plug 9 is engaged with the inside of the bottom cover sleeve 10, forming a positioning fit. The bottom cover sleeve 10 is made of aluminum alloy, and the fixing pin 11 that runs through the front is made of stainless steel. The rear end of the fixing pin 11 is inserted into the end plug 9. Through interference fit and mechanical limit, the end plug 9 and the bottom cover sleeve 10 are firmly connected to prevent the parts from loosening during movement. The bottom end of the bottom cover sleeve 10 is engaged. The modified bottom insert 12 is made of polyoxymethylene (POM) material. Its external chamfered design reduces the risk of scratches from sharp edges, improving safety and facilitating installation and removal. The modified bottom insert 12 works in conjunction with the bottom cover 10 to further enhance the structural strength of the handle's end, distributing stress on the bottom of the handle during impact and ensuring structural stability over long-term use. This improves the overall stability of the racket connection, extends its lifespan, enhances grip comfort and control during shots, and meets the needs of athletes for high-performance badminton rackets.
