In order to improve its shortcomings, the present invention provides a badminton racket that tensions the strings by rotating the racket frame.

[0004] To achieve the above object, the present invention is achieved through the following technical solutions:

[0005] A badminton racket that tensions the racket strings by rotating the racket frame comprises a racket frame, the racket strings are arranged in the racket frame, the lower end of the racket frame is connected to a racket rod, the lower part of the racket rod is provided with a racket handle, the racket frame and the racket rod are hinged via screws, the racket strings comprise transverse threads and longitudinal threads, one end of the transverse threads is connected to the racket frame, and the other end is connected to a clamping ring, the clamping ring abuts against the outer peripheral surface of the racket frame on the racket rod side, one end of the longitudinal threads is connected to the racket frame, and the other end is connected to another clamping ring, the clamping ring abuts against the outer peripheral surface of the racket frame on the racket rod side, a shoulder-shaped protrusion is arranged on the racket rod located on the racket frame side, a latch mechanism for limiting the rotation of the racket frame is arranged on the protrusion, and a connecting line connected to the clamping ring is arranged on the protrusion between the latch mechanism and the racket rod.

[0006] When the present invention is working, when the transverse wire is loose, the clamping ring connected to one end thereof is pulled to connect the clamping ring with the connecting wire provided on the protrusion, and at the same time the pin body in the latch mechanism is pulled out from the blind hole on the outer peripheral surface of the racket frame, so that the racket frame is rotated with the racket rod as the central axis, and the transverse wire outside the racket frame is wound around the racket rod, so as to achieve the purpose of tightening the transverse wire. When the longitudinal wire is loose, the other clamping ring connected to one end thereof is pulled to connect the clamping ring with the connecting wire provided on the protrusion, and at the same time the pin body in the latch mechanism is pulled out from the blind hole on the outer peripheral surface of the racket frame, so that the racket frame is rotated with the racket rod as the central axis, and the longitudinal wire outside the racket frame is wound around the racket rod, so as to achieve the purpose of tightening the longitudinal wire.

[0007] Compared with the prior art, the beneficial effects of the present invention are as follows: since the hinged racket frame cooperates with the connecting wire on the protrusion, when the transverse wire or the longitudinal wire is loose, the clamping ring of the transverse wire or the clamping ring of the longitudinal wire is connected to the connecting wire, and the rotating racket frame winds the transverse wire or the longitudinal wire around the racket rod to tighten the transverse wire or the longitudinal wire. The device has a simple structure, is simple and convenient to operate, can be used in industrial production, and has strong practicality.

DETAILED DESCRIPTION

[0014] The technical solution described in this application is further described below in conjunction with the accompanying drawings and embodiments.

[0015] Example 1: Figure 1-2 As shown, a badminton racket is provided with a racket frame 1, wherein the racket frame 1 is provided with a racket string 2, wherein the lower end of the racket frame 1 is connected to a racket shaft 3, wherein the lower part of the racket shaft 3 is provided with a racket handle 4, wherein the racket frame 1 and the racket shaft 3 are hingedly connected by screws, wherein the racket string 2 comprises a transverse wire 201 and a longitudinal wire 202, wherein one end of the transverse wire 201 is connected to the racket frame 1, and the other end is connected to a clamping ring 5, wherein the clamping ring 5 abuts against the racket shaft 3. On the outer circumference of the frame 1, one end of the longitudinal wire 202 is connected to the racket frame 1, and the other end is connected to another clamping ring 5, the clamping ring 5 is in contact with the outer circumference of the frame 1 on the side of the racket shaft 3, and the racket shaft 3 located on one side of the racket frame 1 is provided with a shoulder-shaped protrusion 301, and the protrusion 301 is provided with a latch mechanism 6 for limiting the rotation of the racket frame 1, and the protrusion 301 located between the latch mechanism 6 and the racket shaft 3 is provided with a connecting line 302 connected to the clamping ring 5. The latch mechanism 6 includes a pin body 601 that passes through the protrusion 301. A shoulder 602 is provided on the pin body 601 between the protrusion 301 and the racket frame 1. A compression spring 603 is sleeved on the pin body 601 between the shoulder 602 and the protrusion 301. One end of the compression spring 603 abuts against the protrusion 301, and the other end abuts against the shoulder 602. A blind hole 101 that matches the pin body 601 is provided on the outer peripheral surface of the racket frame 1 corresponding to the end of the pin body 601. Since the compression spring 603 matches the pin body 601, the compression spring 603 fixes the pin body 601 on the racket frame 1 in normal state, so as to prevent the racket frame 1 from rotating during movement and affecting normal hitting. The latch mechanism 6 is provided with two groups. Due to the existence of the two groups of latch mechanisms 6, the racket frame 1 can be made more firm and stable relative to the racket shaft 3 in normal state.

[0016] During operation, when the badminton racket is used for a long time and causes the transverse wire 201 to be loose, the pin bodies 601 in the two sets of pin structures are pulled out from the corresponding blind holes 101 of the racket frame 1, so that the racket frame 1 can rotate relative to the racket shaft 3, and at the same time, the clamping ring 5 on the racket frame 1 connected to the transverse wire 201 is pulled out to connect it with the connecting wire 302 provided on the protrusion 301 of the racket shaft 3. After the connection is completed, the transverse wire 201 is wound around the racket shaft 3 by rotating the racket frame 1, so as to achieve the purpose of tightening the transverse wire 2. When the badminton racket is used for a long time and the longitudinal thread 202 becomes loose, the pins 601 in the two sets of pin structures are pulled out from the corresponding blind holes 101 of the racket frame 1, so that the racket frame 1 can rotate relative to the racket shaft 3. At the same time, the clamping ring 5 on the racket frame 1 connected to the longitudinal thread 202 is pulled out to connect it with the connecting line 302 provided on the protrusion 301 of the racket shaft 3. After the connection is completed, the longitudinal thread 202 is wound around the racket shaft 3 by rotating the racket frame 1, so as to achieve the purpose of tightening the longitudinal string 2.
