Description

Technical Field

[0001] The invention relates to the technical field of badminton rackets, in particular to an integrally formed badminton racket and a manufacturing method thereof. Background Art

[0002] As we all know, badminton rackets are common sports equipment, generally including a racket frame, a racket shaft, a racket handle, and a joint connecting the racket frame and the racket shaft. Traditional badminton rackets are mostly split structures, using aluminum alloy, titanium alloy, carbon fiber and other materials to make the racket frame and the racket shaft, and then connecting the racket frame and the racket shaft through an internal or external joint. The racket handle is mostly made of wood or plastic structure, with an insertion hole opened at its end, and the end of the racket shaft away from the racket frame is inserted after glue injection, thereby realizing the assembly of the badminton racket body, and then wrapping the handle with anti-slip cloth or rubber strips, and opening a threading hole on the racket frame, and the badminton racket can be obtained after threading.

[0003] The manufacturing method of the prior art is not only time-consuming and labor-intensive, but also lacks stability after the racket handle is connected to the racket frame, which leads to problems such as the handle shaking or even falling off after long-term use. In addition, the rackets produced by the existing manufacturing method are not convenient for replacing damaged racket nets separately, which also results in unnecessary waste of resources. For this reason, we propose an one-piece badminton racket and a manufacturing method thereof. Summary of the invention

[0004] The object of the present invention is to provide an integrally formed badminton racket and a manufacturing method thereof, so as to solve the problems raised in the above-mentioned background technology.

[0007] The second molded body includes a second arm, and a second frame and a second handle are respectively provided on both sides of the second arm. A slot for inserting the protrusion is evenly opened on one side of the second frame. A racket net is closely attached to one side of the second frame adjacent to the first frame, and the racket net is mounted on the protrusion.

[0008] The disassembly and assembly mechanism includes a bracket, two rod bodies fixedly connected to the second arm, and two through holes opened in the first arm, and positioning grooves are opened on the adjacent sides of the two rod bodies, one side of the bracket is fixedly connected to the first arm, the internal thread of the bracket is connected to the second bolt, one end of the second bolt is fixedly connected to a push block, the outer side of the push block is tightly attached to two blocks, the two blocks are fixedly connected to the opposite sides thereof, one side of the slider is movably connected to the first arm, and the other side of the slider is fixedly connected to the positioning block.

[0010] Preferably, a first sliding groove is formed on one side of the first support arm, and an inner side wall of the first sliding groove is slidably connected to the sliding block.

[0011] By adopting the above technical solution, the slider can drive the insert block to maintain stable linear movement.

[0012] Preferably, the first handle and the second handle are both fixedly connected to opposite sides thereof with anti-slip rubber blocks arranged at equal distances.

[0013] By adopting the above technical solution, the stability of the user when holding the whole after the first handle and the second handle are assembled can be improved.

[0014] Preferably, the internal thread of the first frame is connected with a second bolt, and one side of the second frame is provided with a threaded hole for screwing the second bolt.

[0015] By adopting the above technical solution, after the second bolt is screwed into the threaded hole, the firmness of the first frame and the second frame after being assembled can be further improved.
