Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of pickleball rackets, in particular to a pickleball racket with an asymmetric composite structure. BACKGROUND

[0002] As the core equipment of pickleball sports, the structural design of a pickleball racket directly affects the ball hitting feel and competitive performance of athletes. Currently, the pickleball rackets on the market generally adopt a rim wrapping type mounting structure. The design idea of this structure is to wrap and fix the edges of the racket face with a hard rim all around, so as to achieve protection of the edges of the racket face, reduce cracking and damage of the racket face due to collision and friction during use, and prolong the service life of the racket.

[0003] However, this rim wrapping type mounting structure has an undeniable technical defect, which seriously restricts the use performance of the racket. On the one hand, due to the material properties and processing technology, the rim and the racket face are usually made of different materials. The rim is mostly made of hard engineering plastic, which has high hardness and rigidity, while the racket face is mostly made of carbon fiber composite material or modified resin material, which has good elasticity and ball hitting feedback. There is a significant difference in physical properties between the two. On the other hand, during actual ball hitting, athletes cannot completely ensure that each ball hitting is precisely applied to the effective area of the racket face. When the ball accidentally contacts the rim at the edge of the racket face, the stress state of the ball will change abruptly due to the mismatch of the hardness and elasticity of the rim and the racket face, which will change the trajectory of the ball, greatly reduce the accuracy of the ball hitting, and affect the competitive performance of athletes.

[0020] Specifically, when the asymmetric composite structure's pickleball racket described in the embodiment is installed, first, the first face 2 is placed on one side of the substrate 1, then the first clamping column 21 is inserted into one end of the fixed cavity 41, and the first pin 22 is inserted into one end of the first spiral groove 42; at the same time, the second face 3 is placed on the other side of the substrate 1, then the second clamping column 31 is inserted into the other end of the fixed cavity 41, and the second pin 32 is inserted into one end of the second spiral groove 43; then by rotating the fixed column 4 in the forward direction, the first pin 22 moves along the first spiral groove 42 until it moves to the other end of the first spiral groove 42, and the second pin 32 moves along the second spiral groove 43 until it moves to the other end of the second spiral groove 43, so that the first face 2 is tightly attached to one side of the substrate 1, and the second face 3 is tightly attached to the other side of the substrate 1, thereby completing the installation of the pickleball racket.

[0021] When the first face 2 and the second face 3 need to be disassembled, only need to reverse rotation of the fixed column 4, so that the first pin 22 moves to one end of the first spiral groove 42, and the second pin 32 moves to one end of the second spiral groove 43, that is, the first face 2 and the second face 3 can be taken out.
