Description

Technical Field

[0001] The utility model belongs to the technical field of badminton racket connecting pieces, in particular to an external three-way piece for a badminton racket. Background Art

[0002] The tee of a badminton racket refers to one of the important parts connecting the racket frame and the racket shaft. It is also a key component of a badminton racket. The tee can affect the racket's performance characteristics such as strength, flexibility and control. Therefore, when purchasing a badminton racket, the quality and design of the tee are also one of the important factors to consider.

[0003] For example, the invention with publication number CN211536421U relates to a carbon fiber badminton racket, comprising: a racket frame, a T-shaped fitting, a middle tube and a handle. One end of the middle tube is fixedly connected to the racket frame, the T-shaped fitting is placed inside the tee at the connection between the middle tube and the racket frame, and the handle is arranged at the other end of the middle tube. The handle, racket frame and middle tube are all made of carbon fiber. The utility model uses the T-shaped fitting to be placed directly inside the tee, which can significantly improve the strength and can disperse part of the impact force to the racket frame and the middle tube, making the force more even and more durable.

[0004] The above-mentioned device makes the force on the badminton racket more uniform through the design of the three-way piece. However, after the badminton racket shaft is inserted into the middle tube, it is mostly fixed by glue or bolts. Therefore, it may cause the racket shaft to loosen and fall off after a period of use, thereby affecting the accuracy of hitting the ball. Therefore, a three-way piece for external connection of the badminton racket is proposed to solve the problems raised in the background technology. Utility Model Content

[0005] In order to solve the problems raised in the above background technology, the utility model provides an external three-way component for a badminton racket, which has the advantage of achieving a good fixing effect between the three-way component and the racket shaft.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solution: a badminton racket external three-way component includes a three-way joint, the left and right ends of the bottom of the three-way joint are each provided with a racket frame connection hole, the middle part of the top of the three-way joint is provided with a racket shaft connection hole, and the interior of the three-way joint is fixedly connected with a conical protrusion.

[0007] Preferably, the three-way joint is in a T-shape, and both left and right sides of the outer wall of the three-way joint are in an arc shape, which is used to enhance the hardness of the outer portion of the three-way joint.

[0008] Preferably, the three-way joint is made of aluminum alloy, and the racket frame connecting hole and the racket shaft connecting hole are perpendicular to each other.

[0009] Preferably, the bottom of the conical protrusion is in the shape of an equilateral triangle, and the size of the bottom of the conical protrusion ranges from 5 to 5.5 centimeters.

[0010] Preferably, a gap is left between the conical protrusion and the inner wall of the tee joint.

[0011] Preferably, the diameter of the racket frame connecting hole is 9.1 cm, and the diameter of the top end of the three-way joint is 9 cm.

[0012] Preferably, the exteriors of the racket frame connecting hole and the racket shaft connecting hole are both arc-shaped.

[0013] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0014] The utility model achieves a good effect of fixing the racket rod by cooperating between the three-way joint and the conical protrusion and other structures. The racket rod is inserted into the interior of the three-way joint, and then the bottom of the racket rod abuts against the outer wall of the conical protrusion, so that the glue will not completely enter the interior of the middle rod, so that the amount of glue between the middle rod and the racket rod connecting hole is increased, thereby increasing the friction, thereby preventing the racket rod from loosening or sliding during use, and thereby improving the overall strength and stability of the device.

[0020] The following will be combined with the 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.

[0021] like Figures 1 to 4 As shown, the utility model provides a three-way component for connecting a badminton racket, including a three-way joint 1. The left and right ends of the bottom of the three-way joint 1 are each provided with a racket frame connecting hole 2, the middle part of the top of the three-way joint 1 is provided with a racket shaft connecting hole 3, and the interior of the three-way joint 1 is fixedly connected with a conical protrusion 4.

[0022] The above solution is adopted: the racket rod is inserted into the interior of the three-way joint 1, and then the bottom of the racket rod abuts against the outer wall of the conical protrusion 4, so that the glue will not completely enter the interior of the middle rod, and the amount of glue between the middle rod and the racket rod connecting hole 3 is increased, thereby increasing the friction, thereby preventing the racket rod from loosening or sliding during use, and thereby improving the overall strength and stability of the device.

[0023] like Figures 1 to 4 As shown, the tee joint 1 is in a T-shape, and both left and right sides of the outer wall of the tee joint 1 are in an arc shape, which is used to strengthen the hardness of the outer portion of the tee joint 1 .

[0024] The above solution is adopted: the outer wall of the three-way joint 1 is in an arc shape, which enables the three-way joint 1 to effectively disperse and withstand forces from different directions. Compared with a straight line or a plane structure, the arc structure is less likely to deform when subjected to force, thereby improving the strength and stability of the three-way joint 1. At the same time, the arc design can also reduce air resistance, so that the racket is smoother when swinging, which helps to improve the hitting speed and accuracy.

[0025] like Figures 1 to 4 As shown, the three-way joint 1 is made of aluminum alloy material, and the racket frame connecting hole 2 and the racket shaft connecting hole 3 are perpendicular to each other.

[0026] The above solution is adopted: the three-way joint 1 is made of aluminum alloy material. Its function is that since aluminum alloy material has better rigidity and durability, the three-way piece made of aluminum alloy material can provide a faster ball speed and a more stable hitting feel.

[0027] like Figures 1 to 4 As shown, the bottom of the conical projection 4 is in the shape of an equilateral triangle, the size of the bottom of the conical projection 4 ranges from 5 to 5.5 cm, a gap is left between the conical projection 4 and the inner wall of the tee joint 1, the diameter of the frame connecting hole 2 is 9.1 cm, and the diameter of the top of the tee joint 1 is 9 cm.

[0028] The above solution is adopted: the bottom of the conical protrusion 4 is in the shape of an equilateral triangle, which can effectively prevent the racket shaft from rotating inside the tee joint 1, thereby ensuring that the racket shaft and the racket head always remain in the correct direction, thereby providing a better batting experience. The size range of the bottom of the conical protrusion 4 is between 5 and 5.5 cm. Its function is that if the size of the conical protrusion 4 is less than 5 cm, then the gap left between the conical protrusion 4 and the inner wall of the tee joint 1 will be larger, thereby resulting in a decrease in the wrapping of the tee joint 1 on the racket handle.

[0029] like Figures 1 to 4 As shown, the exteriors of the racket frame connecting hole 2 and the racket shaft connecting hole 3 are both arc-shaped.

[0030] The above solution adopts the arc-shaped outer walls of the racket frame connecting hole 2 and the racket shaft connecting hole 3, which can effectively reduce the sharp edges of the outer walls of the racket frame connecting hole 2 and the racket shaft connecting hole 3, thereby preventing the user's hands from being scratched, thereby improving the comfort during exercise. At the same time, the arc-shaped design can also improve the overall aesthetics of the device.

[0031] The working principle and usage process of the present invention are as follows: the operator inserts the two ends of the racket frame into the two racket frame connecting holes 2 respectively, and uses a fixing ring to fix the two ends of the racket frame to the three-way joint 1, and then inserts the racket rod into the racket rod connecting hole 3 until the inner wall of the racket rod fits with the outer wall of the conical protrusion 4, thereby ensuring the correct position of the racket rod and avoiding the racket rod from being offset or misplaced. Subsequently, the conical protrusion 4 is used to enhance the connection area between the racket rod and the three-way joint 1, thereby increasing the friction force, so that the glue in the three-way joint 1 can better wrap the racket rod, thereby preventing the racket rod from loosening or sliding during use, thereby increasing the overall stability of the device.

[0032] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0033] 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.
