Description

Technical Field

[0001] The utility model relates to the technical field of table tennis racket rubbers, in particular to a rubber structure used for table tennis rackets. Background Art

[0002] In the prior art, table tennis racket rubber is an important component of table tennis racket, which is a kind of rubber glued to the bottom plate of table tennis racket. The selection of suitable table tennis rubber in combination with different playing styles plays a vital role in the performance of players and the outcome of the game. Table tennis racket rubber is generally divided into two categories: granular rubber and anti-rubber. Granular rubber is divided into positive rubber, raw rubber and long rubber. Positive rubber refers to granular rubber whose length is equal to the radius of the cross section of the particle. Long rubber is longer than the radius, and raw rubber is shorter than the radius. Among them, long rubber has a good arc prevention effect. Various table tennis playing styles are combined with looping, and long rubber can well restrain these playing styles. Both positive rubber and raw rubber have good rebound and stability, low friction and other characteristics. Because of its long and soft particles, long rubber often plays a more strange ball, rebounds quickly and is difficult to add rotation. Anti-rubber refers to a rubber with a smooth surface, and the particles of the rubber face inward. Its characteristics are strong rotation force, stable hitting, and easy control. It is suitable for looping or looping combined with fast attack. Because of its stable hitting and good ball control, it is also the first choice for beginners. The rubber column on the base skin of traditional table tennis rackets is a cylindrical structure, and its elasticity depends on the length and diameter of the rubber column. Since the cross-sectional modulus of the cylinder has no variable factors, it is difficult and technically demanding to achieve the change of the ball trajectory, and it is easy for the opponent to master, which reduces the difficulty of table tennis confrontation and the challenge of playing.

[0003] The Chinese utility model patent with application number: 202321235942.9 discloses a table tennis racket rubber structure, including a rubber body, the rubber body also includes a rubber plate, the bottom of the rubber plate is fixedly connected to an elastic plate, the bottom of the elastic plate is fixedly connected to a rubber sponge, the inner cavity of the rubber plate is provided with an X-shaped pillar, the two ends of the X-shaped pillar are respectively fixedly connected to the top and bottom of the inner cavity of the rubber plate, the top of the rubber plate is fixedly connected to cylindrical particles, the surface of the rubber plate is provided with a protective mechanism, and the protective mechanism also includes a protective cover.
