DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the utility model will be clearly and completely described in connection with the drawings in the embodiments of the utility model, and in the description of the utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the utility model and simplifying the description, and do not indicate or imply that the devices or elements indicated must have a particular orientation, be constructed and operated in a particular orientation, therefore, it cannot be understood as a limitation on the utility model, obviously, the described embodiments are only a part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the utility model.

[0023] A counterweight badminton racket, as shown in Figure 1 、 Figure 4 、 Figure 5 The utility model discloses a handle of racket's cut structure schematic view.

[0024] As shown in Figure 2As shown, the counterweight 5 is uniformly provided with several blocks 6 along its length direction, and the blocks 6 are provided with counterweight blocks 7. The counterweight blocks 7 are the main source of the counterweight of the inner handle 2. By increasing or decreasing the counterweight blocks 7, the weight of the inner handle 2 can be changed. When the weights of the two side counterweights 5 are different, that is, the number of the placed counterweight blocks 7 is different, the center of gravity of the inner handle 2 will change. On a single counterweight 5, the same number of counterweight blocks 7, but placed in different positions, will also change the center of gravity of the inner handle 2. Therefore, the user can adjust the weight and the center of gravity of the inner handle 2 according to these items to adapt to their own needs, and have more detailed adjustable options, so that the user can adjust the racket handle 1 to a state more suitable for their own hand feeling.

[0025] As shown in Figure 2 , two first button magnets 18 are arranged on the two sides of the counterweight block 7, and two second button magnets 19 are arranged on the two sides of the block groove 6 of the counterweight 5 and are magnetically attracted to the first button magnets 18. Therefore, when the user installs the counterweight block 7, he only needs to embed it into the block groove 6, and the first button magnet 18 and the second button magnet 19 will be magnetically attracted to each other and fit together, thereby stabilizing the counterweight block 7. When it is necessary to disassemble the counterweight block 7, it only needs to overcome the magnetic force of the first button magnet 18 and the second button magnet 19 to pull it out, and the counterweight block 7 can be removed.

[0026] As shown in Figure 3 , Figure 4 , Figure 5 , the bottom of the racket handle 1 is provided with a stabilizing assembly, and the bottom center of the inner handle 2 is provided with an installation groove 8 corresponding to the number of counterweight grooves 4, and the stabilizing assembly is arranged in the installation groove 8. The stabilizing assembly is used to stabilize the counterweight 5 embedded in the counterweight groove 4 and ensure the use effect of the racket. The installation groove 8 is provided with a mounting seat 11 on one side of the middle part of the inner handle 2, and the stabilizing assembly further includes a limiting rotating block 9 and a rotating shaft 10. The rotating shaft 10 is fixed to the mounting seat 11 by embedding, and the limiting rotating block 9 is sleeved on the rotating shaft 10 and is rotatably connected with the rotating shaft 10. When the limiting rotating block 9 is installed, the rotating shaft 10 is first embedded into the limiting rotating block 9, and then the two ends of the rotating shaft 10 are embedded in the mounting seat 11. The limiting rotating block 9 adopts a water drop cross-section shape, and the end towards the outside is a sharp end. An opening 12 is arranged between the installation groove 8 and the counterweight groove 4. The counterweight 5 is provided with a limiting groove 13, and the sharp end of the limiting rotating block 9 extends into the limiting groove 13 through the opening 12.

[0027] As shown in Figure 3 , Figure 4 , Figure 5As shown, the limiting groove 13 is located on the back side of the counterweight 5 near the bottom, and the limiting rotating block 9 can rotate upward or downward. When the handle 1 is in the correct holding position, the limiting rotating block 9 can rotate downward to the top side to be in the horizontal state, and can rotate upward to be completely retracted into the installation groove 8. When the counterweight 5 is embedded into the counterweight groove 4, the tip of the limiting rotating block 9 is embedded into the limiting groove 13, and the top surface of the limiting rotating block 9 is in abutment with the counterweight 5 and is in the horizontal state, thereby limiting the counterweight 5 from being separated from the counterweight groove 4.

[0028] As shown in Figure 4 , Figure 5 , a groove is arranged on the limiting rotating block 9, and a torsion spring 14 is arranged in the groove. The torsion spring 14 is sleeved on the rotating shaft 10, and the two ends thereof are in abutment with the limiting rotating block 9 and the inner handle 2 respectively. Therefore, the torsion spring 14 drives the limiting rotating block 9 to rotate towards the bottom of the inner handle 2, and the limiting rotating block 9 will remain in the horizontal state without other external force. When the limiting rotating block 9 is in the horizontal state, the bottom surface thereof is in the inclined state towards the top of the inner handle 2. Therefore, during the embedding of the counterweight 5, the limiting rotating block 9 is pressed to be retracted into the installation groove 8, so as not to affect the installation of the counterweight 5. When the counterweight 5 is embedded into the limiting groove 13 and the limiting rotating block 9 is aligned, the limiting rotating block 9 is reset under the action of the torsion spring 14, and the counterweight 5 is limited.

[0029] As shown in Figure 5 , a spring 15 is arranged in the counterweight groove 4, and the two ends of the spring 15 are in abutment with the inner handle 2 and the counterweight 5 respectively. The end of the spring 15 in abutment with the inner handle 2 is on the groove bottom of the counterweight groove 4, and can be directly fixed on the inner handle 2. Therefore, under the action of the spring 15, the counterweight 5 embedded into the counterweight groove 4 will have a force to move outward, thereby increasing the pressing effect with the limiting rotating block 9, and increasing the stability of the counterweight 5 to prevent shaking.

[0030] As shown in Figure 4 , Figure 5 , a pressing cap 16 is slidably arranged in the installation groove 8, and the pressing cap 16 is in abutment with the limiting rotating block 9. A limiting ring 17 is fixedly arranged on the installation groove 8, and is used to limit the pressing cap 16 from being separated from the installation groove 8. Therefore, the user can press the pressing cap 16 to move inward, and press the limiting rotating block 9 to rotate to be retracted into the installation groove 8, so as to release the limitation on the counterweight 5. Under the action of the spring 15, the counterweight 5 is popped out, so that the limiting groove 13 is misaligned with the limiting rotating block 9. The user can take out the counterweight 5 to adjust the multiple weights and the center of gravity.

[0031] As shown in Figure 1 , Figure 5As shown, the bottom of the handle 1 is sleeved with a dust cover 20, which can prevent the pressure cover 16 from being touched by mistake, so that the user can use the racket more conveniently.

[0032] It is obvious for those skilled in the art that the present application is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or essential characteristics of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting, and the scope of the present application is defined by the appended claims rather than the above description, and all changes falling within the meaning and scope of the equivalent elements of the claims are intended to be included in the present application.
