[0010] Furthermore, a rubber ring is fixed on the inner wall of the extrusion nut, and the rubber ring is in contact with one side of the counterweight.

[0011] Beneficial effects of the utility model:

[0012] The badminton racket with adjustable center of gravity can squeeze different numbers of counterweights to limit their position when in use. The number of counterweights used can be used to select and adjust the weight of the center of gravity to meet the adjustment requirements of different center of gravity.

[0013] The invention relates to a badminton racket with an adjustable center of gravity. The ring groove cooperates with the counterweight block for positioning installation, and provides a support point for the counterweight block during positioning installation. The limiting column cooperates with the limiting hole to realize the connection and fixation between the counterweight blocks. Later, when the extrusion bolt is rotated to be loosened, the counterweight block can be quickly installed and disassembled through the opening. BRIEF DESCRIPTION OF THE DRAWINGS

[0019] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0020] See also Figures 1 to 4The utility model provides a technical solution: a badminton racket with adjustable center of gravity, comprising a support column 1, a handle 2 being fixed to one end of the support column 1, a ring seat 3 being fixedly installed to the other end of the support column 1, fixing grooves 4 being respectively opened at both ends of the ring seat 3, a counterweight assembly being movably installed inside the fixing groove 4, the counterweight assembly comprising a counterweight block 6, an extrusion nut 5 being movably installed on the counterweight block 6, a fixing column 10 being fixed on the extrusion nut 5, an opening 8 being opened on the counterweight block 6, the fixing column 10 being movably installed inside the opening 8, an opening 9 being opened on the side of the opening 8, the opening 9 being matched with the diameter of the fixing column 10, so as to facilitate the horizontal removal of the counterweight block 6 through the opening 9.

[0021] In this embodiment, a limiting column 7 is fixed to the bottom of the counterweight 6, a limiting hole is opened on the top of the counterweight 6, one end of the limiting column 7 is movably installed inside the limiting hole, an annular groove 13 is opened on the inner wall of the fixing groove 4, the counterweight 6 is movably installed inside the annular groove 13, a threaded hole 12 is opened at the bottom of the annular groove 13, a threaded column 11 is rotatably installed inside the threaded hole 12, the threaded column 11 is fixed to one end of the fixing column 10, a rubber ring is fixed on the inner wall of the extrusion nut 5, the rubber ring is in contact with one side of the counterweight 6, and the rubber ring is deformed under the extrusion of the extrusion nut 5 in the later stage, and the friction with the counterweight 6 is increased after deformation, thereby limiting and fixing the counterweight 6.

[0022] When the device is in use, the counterweight block 6 of appropriate gravity is rotated according to the requirements of the center of gravity and installed in the fixed groove 4 at the corresponding position. When it is necessary to attack and play, the center of gravity can be placed in front of the ring seat 3, and the center of gravity can be placed between the support column 1 and the ring seat 3 when playing defensively. When adjusting the center of gravity, according to the user's usage habits, the center of gravity can be adjusted by rotating the appropriate number of counterweight blocks 6 installed in the fixed groove 4. When the counterweight blocks 6 are installed, the bottom counterweight block 6 is installed in the inside of the ring groove 13, and the ring groove 13 realizes the counterweight. The weight block 6 is positioned and installed. During the positioning and installation, the annular groove 13 provides a limiting support for the counterweight block 6. When the counterweight blocks 6 are stacked and installed, the limiting column 7 enters into the inside of the limiting hole, so that the counterweight blocks 6 at adjacent positions are limited and installed. After the installation is completed, the direction of the opening 9 of the counterweight block 6 is the same as the direction of the racket swing, avoiding the danger of the counterweight block 6 being thrown out when the racket is swung. In addition, when the counterweight block 6 is removed, the extrusion nut 5 loses the extrusion on the counterweight block 6, and the counterweight block 6 moves upward and then moves horizontally, and the movement realizes the rapid disassembly of the counterweight block 6.

[0023] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or basic characteristics of the present invention.
