A golden nanmu table tennis racket with good rebound effect

technical field

The patent of the invention relates to the technical field of sporting goods, in particular to a table tennis racket made of golden nanmu wood with good rebound effect.

Background technique

Table tennis is China's national game, and it is also a ball sport that is popular all over the world. Table tennis is a skill-based event mainly based on skills and supplemented by physical fitness. In table tennis training or entertainment, different people have different habits of holding rackets, which are generally divided into horizontal and straight. The horizontal is generally good for backhand attack; Good for backhand grip and attack. Therefore, the two sides of the batting plate of a general table tennis racket are glued with a layer of rubber to increase the hitting elasticity when hitting the ball in different ways of holding the racket, so that the ball has sufficient running speed.

Notification number is that the Chinese patent of CN207356506U discloses a kind of table tennis racket, comprises handle, baffle plate, bottom plate, upper elastic rubber, lower elastic rubber, finger hole, head, waist, sliding plate, center of gravity block, hollow groove, cover plate , the first magnet and the second magnet, the front end of the handle is provided with a ball baffle, the inside of the ball baffle is provided with a base plate, the upper part of the base plate is provided with an upper elastic rubber, the lower part of the base plate is provided with a lower elastic rubber, and the ball baffle is provided with a There is a finger hole, and the right side of the finger hole is provided with a spacer, the handle is provided with a waist, and the left side of the waist is provided with a left waist, the right side of the waist is provided with a right waist, the rear end of the waist is provided with a head, and the inside of the handle A hollow groove is provided, and the hollow groove is provided with a sliding plate, the upper part of the sliding plate is provided with a center of gravity block, the inside of the hollow groove is provided with a first magnet, the rear end cover of the sliding plate is provided with a cover plate, and the cover plate is provided with a second magnet. Two magnets.

Although this prior art solution increases the contact area between the hand and the handle by providing finger holes, thereby meeting the requirements of different grip postures, in actual use, the upper elastic rubber and the lower elastic rubber need to be used to improve the grip when hitting the ball. Rebound effect, the elastic rubber is easy to fall off after a long time of use, and it is also easy to age, so the rebound effect of hitting the ball is reduced; on the other hand, pasting the elastic rubber will also increase the manufacturing process steps and costs of the racket. Therefore, develop a kind of inelastic rubber and the good racket of hitting resilience has bigger market prospect.

As a core board layer, it can ensure the overall strength of the table tennis racket. At the same time, it can effectively control the weight of the racket and increase the grip feeling of the entire racket.

Further, the hitting plate is elliptical, and a handle bonding portion for gluing the handle of the racket is extended from one end of the long axis of the elliptical hitting plate.

By adopting the above technical solution, the bonding part of the handle can facilitate the glueing and fixing of the handle of the racket.

Further, the racket handle includes two racket half handles which are respectively glued and fixed to the upper surface and the lower surface of the bonding part of the handle, and the racket half handles are all made of golden nanmu.

By adopting the above-mentioned technical scheme, two racket half handles of golden nanmu can be quickly and firmly bonded and fixed to the bonding part of the handle, thereby improving the production efficiency of the racket while ensuring the firmness of the handle of the racket.

Further, the upper surface and the lower surface of the bonding part of the handle are provided with slots, and the side of the half-shaft of the racket close to the bonding part of the handle is provided with an embedded projection adapted to the slots.

By adopting the above technical solution, the embedding groove can quickly locate the embedding protrusion, and also enables the half handle of the racket to be more closely fitted and stably fixed to the bonding part of the handle.

Further, a sealant layer is provided between the contact surface of the embedding protrusion and the embedding groove.

By adopting the above technical solution, the sealant layer can make the embedded projection and the embedded groove more firmly together, and can also achieve a good sealing and moisture-proof effect, thereby prolonging the bonding strength and service life of the racket handle.

In summary, the patent of the present invention has the following beneficial effects:
