Description

Technical Field

[0001] This utility model relates to the field of badminton racket technology, specifically to a badminton racket that prevents the shaft from slipping off. Background Technology

[0002] Badminton is a popular sport that cultivates agility, judgment, and reaction speed, while also improving speed, strength, and endurance. It offers both recreational and exercise benefits. However, current badminton racket technology typically involves inserting one end of the racket shaft into the T-joint and then securing it with glue. This method of connection can easily lead to the racket shaft detaching after prolonged use. Therefore, this paper proposes a badminton racket design that enhances the connection strength between the racket shaft and the T-joint to prevent detachment. Summary of the Invention

[0003] The purpose of this invention is to provide a badminton racket that prevents the shaft from slipping off, in order to solve the above problems.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a badminton racket to prevent shaft slippage, comprising a handle, a racket shaft retractably installed within the handle, a racket head connected to the racket shaft, and a T-joint connecting the racket shaft and the racket head; characterized in that one end of the racket shaft is provided with a connecting stud connected to the T-joint; the T-joint is provided with a threaded hole adapted to the connecting stud; and a connecting rubber sleeve is installed between the racket shaft and the T-joint to protect and improve the connection strength.

[0005] Preferably, the connecting rubber sleeve is provided with a mounting through hole that is compatible with the racket shaft, and is installed between the racket shaft and the tee using a tight fit method.

[0006] Preferably, the handle is provided with a telescopic guide groove that guides the racket shaft.

[0007] Preferably, one end of the racket shaft is equipped with a telescopic guide block that is adapted to the telescopic guide groove.

[0008] Preferably, both the telescopic guide block and the telescopic guide groove are polygonal structures.

[0009] Preferably, the handle is also equipped with a locking head for locking the extension and retraction adjustment of the racket shaft.

[0010] The beneficial effects of this utility model are: by rotating the connecting stud on the racket shaft into the threaded hole on the tee, the connection strength between the racket shaft and the tee is improved, and the occurrence of the badminton racket coming off the shaft during the hitting process is reduced;

[0011] By installing a connecting rubber sleeve at the connection between the racket shaft and the tee, not only is the connection between the racket shaft and the tee sealed, preventing liquid from flowing into the connection and causing rust on the connecting stud and threaded hole, but the strength of the connection between the racket shaft and the tee is also further improved, preventing the racket shaft from rotating and detaching from the tee during the hitting process.

[0017] The following description, in conjunction with the accompanying drawings, further illustrates a badminton racket designed to prevent shaft slippage according to this invention.

[0018] It should be noted that all directional indications in the embodiments of the present invention, such as up, down, left, right, front, back, etc., are only used to explain the relative positional relationship and movement of the components in a specific posture as shown in the attached figure. If the specific posture changes, the directional indication will also change accordingly.

[0019] See appendix Figure 1-4As shown, this embodiment of a badminton racket for preventing shaft slippage includes a handle 1, a racket shaft 2 retractably installed within the handle 1, a racket head 3 connected to the racket shaft 2, and a T-joint 4 connecting the racket shaft 2 and the racket head 3. The racket shaft 2 is characterized by a connecting stud 201 at one end, which connects to the T-joint 4; the T-joint 4 has a threaded hole 401 adapted to the connecting stud 201; a connecting rubber sleeve 5 is installed between the racket shaft 2 and the T-joint 4 to protect and enhance the connection strength; and the racket head 3 is secured by rotating the connecting stud 201 on the racket shaft 2. The connection between the racket shaft 2 and the tee 4 is strengthened by inserting it into the threaded hole 401 on the tee 4, reducing the likelihood of the badminton racket coming off the shaft during hitting. The rubber sleeve 5 is installed at the connection between the racket shaft 2 and the tee 4, which not only seals the connection between the racket shaft 2 and the tee 4, preventing liquid from flowing into the connection and causing rust on the connecting stud 201 and the threaded hole 401, but also further strengthens the connection between the racket shaft 2 and the tee 4, preventing the racket shaft 2 from rotating and coming off the tee 4 during hitting.

[0020] See appendix Figure 4 As shown, the connecting rubber sleeve 5 is provided with an installation through hole 501 that is adapted to the racket shaft 2, and is installed between the racket shaft 2 and the tee 4 by means of tight fit; by means of tight fit, the installation through hole 501 on the connecting rubber sleeve 5 is fitted onto the racket shaft 2, thereby facilitating the fixing of the connecting rubber sleeve 5 and preventing the connecting rubber sleeve 5 from sliding along the racket shaft 2 during use.

[0021] See appendix Figure 1 As shown, the handle 1 is provided with a telescopic guide groove 101 that guides the racket shaft 2; one end of the racket shaft 2 is equipped with a telescopic guide block 202 that is adapted to the telescopic guide groove 101; both the telescopic guide block 202 and the telescopic guide groove 101 are polygonal structures; the telescopic guide block 202 on the racket shaft 2 is used to guide the racket shaft 2 to extend and retract along the telescopic guide groove 101, thereby facilitating the adjustment of the racket shaft 2; by setting the telescopic guide block 202 and the telescopic guide groove 101 as polygonal structures, the stability of the racket shaft 2 adjustment is improved.

[0022] See appendix Figure 1 As shown, the handle 1 is also fitted with a locking head 6 for locking the extension and retraction of the racket shaft 2 via a threaded connection. The racket shaft 2 can be locked after adjustment by tightening the locking head 6 onto the handle 1 via the threaded connection. When the locking head 6 is loosened, the racket shaft 2 can be adjusted along the handle 1 via a rope, thus facilitating the adjustment and locking of the racket shaft 2.

[0023] The installation process of this utility model involves first fitting the connecting rubber sleeve 5 through the mounting through hole 501 and the connecting stud 201 onto the racket shaft 2. Then, the connecting stud 201 on the racket shaft 2 is installed into the threaded hole 401 of the tee 4, and the racket shaft 2 is rotated. The racket shaft 2 drives the connecting stud 201 to rotate, installing the connecting stud 201 into the threaded hole 401 of the tee 4, thus connecting the racket shaft 2 and the tee 4. Then, the connecting rubber sleeve 5 is pulled upwards so that half of the connecting rubber sleeve 5 is on the racket shaft 2 and half is on the tee 4, sealing the racket shaft 2 and the tee 4 and further improving the connection strength to prevent the shaft from coming off.

[0024] The above embodiments are illustrative of the present invention and are not intended to limit the present invention. Any simple modifications to the present invention are within the protection scope of the present invention.
