Description

Technical Field

[0001] The utility model belongs to the technical field of table tennis, in particular to a novel AB structure sponge suitable for a long rubber playing method of table tennis. Background Art

[0002] Table tennis is a world-popular ball sport that includes offense, confrontation and defense, and the table tennis racket patch is one of the important factors affecting the performance of table tennis players.

[0003] The long-rubber style of table tennis is often based on defense and combined with offense. Therefore, force unloading is essential in high-power confrontations. However, the existing table tennis racket soles are too hard and elastic, and amateur players cannot catch the ball in attack. Therefore, the utility model provides a table tennis racket patch that can improve the performance of the table tennis sole, has shock absorption and force unloading effects, and can help players better catch the ball and attack with increased fault tolerance when playing with long rubber. Utility Model Content

[0004] In order to solve the above technical problems, the utility model provides a table tennis racket patch that can improve the performance of the table tennis baseboard, has shock absorption and force release effects, and can help players better catch the ball and attack with improved fault tolerance when playing with long rubber.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] A novel AB structure sponge suitable for long rubber table tennis playing style, comprising a base plate and a cork structure layer. The base plate is made of hardwood, and a group of cork structure layers are adhered to the top and bottom walls of the base plate. The cork structure layer is used to soften the base plate.

[0007] The two groups of cork structural layers both include cork pads, PET films, and EVA sponge layers. The shape of the cork pads is the same as that of the base plate. The surfaces of the cork pads away from the base plate are adhered to the PET film, the surfaces of the cork pads close to the base plate are adhered to the EVA sponge layer, and the surface of the EVA sponge layer away from the cork pads is adhered to the base plate.

[0008] Preferably, the elastic coefficient of the cork pad is smaller than the elastic coefficient of the sponge, the thickness of the PET film and the EVA sponge layer is between 0.02 mm and 1.0 mm, the material of the EVA sponge layer is EVA sponge or low-hardness polyurethane cotton, and the PET film is extremely thin and rigid. The long rubber single rubber directly contacts the PET film, and after being subjected to point force, it is converted into a regular surface depression, which disperses the force, and the initial rigidity can make the long rubber particles quickly fall over and produce weirdness. The inner EVA sponge layer is soft and rebounds slowly under force and can hold the ball, so that the cork structure layer forms the characteristics of hard outside and soft inside, thereby dispersing the force of the oncoming table tennis ball.

[0009] Preferably, the side wall of the PET film away from the bottom plate in each soft wood structure layer is adhered with granular rubber, and the shape of the granular rubber is the same as that of the bottom plate.

[0010] Preferably, a rectangular parallelepiped-shaped grip is fixedly connected to a part of the outer periphery of the bottom plate, and waist-reducing plates are fixedly connected to the top wall and the bottom wall of the grip, and the waist-reducing plates can facilitate the player to better hold the table tennis racket.

[0011] Preferably, each soft wood structure layer further includes a gap layer, a gap layer is opened in the cork pad, and an air injection hole is provided on the outer periphery of the cork pad.

[0012] Preferably, in another embodiment of the present application, the cork pad, the PET film and the EVA sponge layer can be arranged and combined in different orders without affecting the characteristic of the outer hard and inner soft of the soft wood structure layer.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. By gluing the cork pad on both sides of the bottom plate with glue, the hardness of the bottom plate is softened, and the elastic coefficient of the cork pad is less than that of the sponge, which means that it can not only provide a certain supporting force, but also better absorb the impact of the table tennis ball, reduce the vibration transmission to the player's hand, effectively absorb the impact force generated when hitting the ball, reduce the harm to the wrist and arm, improve the comfort and controllability of the player's long pimple rubber play method, enable the player to better attack and improve the error tolerance rate.

[0015] 2. Through the design of the gap layer, amateur players can inject fillers with different materials or densities (such as gases, liquids or solid materials with specific hardness) into the gap layer according to their own training stages or competition needs, so as to realize the rapid adjustment of the hardness of the table tennis racket, improve the flexibility and adaptability of the table tennis racket, meet the diversified use needs without frequently replacing the patches, improve the convenience of the table tennis racket, and reduce the economic burden of amateur players.

[0025] Embodiment 1

[0026] As shown in the attached Figure 1 to the attached Figure 3 figures:

[0027] The present utility model provides a new type of AB - structured sponge suitable for the long - pimple rubber play of table tennis, including a bottom plate 1 and a cork - wood structure layer 2. The bottom plate 1 is made of a hard wooden board, and a set of cork - wood structure layers 2 are adhered to both the top wall and the bottom wall of the bottom plate 1. The cork - wood structure layer 2 is used to soften the bottom plate 1;

[0028] The two groups of cork structure layers 2 both include a cork pad 21, a PET film 22, and an EVA sponge layer 23. The shape of the cork pad 21 is the same as that of the base plate 1. The surface of the cork pad 21 away from the base plate 1 is adhered to the PET film 22, and the surface of the cork pad 21 close to the base plate 1 is adhered to the EVA sponge layer 23. The surface of the EVA sponge layer 23 away from the cork pad 21 is adhered to the base plate 1.

[0029] Specifically, the elastic coefficient of the cork pad 21 is smaller than the elastic coefficient of the sponge, the thickness of the PET film 22 and the EVA sponge layer 23 is between 0.02 mm and 1.0 mm, and the material of the EVA sponge layer 23 can be EVA sponge or low-hardness polyurethane cotton. The PET film 22 is extremely thin and rigid. The long rubber single rubber directly contacts the PET film 22, and after being subjected to point force, it is converted into a regular surface depression, which disperses the force, and the initial rigidity can make the long rubber particles quickly fall over and produce weirdness. The inner EVA sponge layer 23 is soft and rebounds slowly under force and can hold the ball, so that the cork structure layer 2 has the characteristics of being hard on the outside and soft on the inside, thereby dispersing the force of the oncoming table tennis ball.

[0030] Specifically, the side walls of the PET film 22 in each group of the cork structure layers 2 away from the bottom plate 1 are adhered with the granular rubber 3 , and the shape of the granular rubber 3 is the same as that of the bottom plate 1 .

[0031] Specifically, in another embodiment of the present application, the cork pad 21, the PET film 22 and the EVA sponge layer 23 can be arranged and combined in different orders without affecting the characteristics of the cork structure layer 2 being hard on the outside and soft on the inside.

[0032] Specifically, part of the outer periphery of the bottom plate 1 is fixedly connected to the rectangular handle 4, and the top wall and the bottom wall of the handle 4 are fixedly connected to the waist plate 5. The waist plate 5 can help players better hold the table tennis racket.

[0033] By gluing cork pads 21 on both sides of the bottom plate 1, the hardness of the bottom plate 1 is softened, and the elastic coefficient of the cork pads 21 is smaller than that of the sponge, which means that it can not only provide a certain support force, but also better absorb the impact of the table tennis ball, reduce the vibration transmitted to the player's hands, effectively absorb the impact force generated when hitting the ball, reduce damage to the wrist and arm, improve the comfort and control of the player's long rubber playing style, and enable the player to attack better and increase the fault tolerance rate.

[0034] Example 2

[0035] During the process of amateur players training their table tennis skills, the demand for the hardness of the table tennis racket will constantly change. However, the hardness of the cork structure layer 2 cannot be adjusted, which not only increases the economic burden on amateur players to replace the patches, but also reduces the practicality and flexibility of the table tennis racket patches. Therefore, Example 2 makes further improvements to Example 1.

[0036] As shown in the Figure 4 accompanying drawings, each group of the cork structure layer 2 further includes a gap layer 24. A gap layer 24 is formed inside the cork pad 21, and an air injection hole (not shown in the figure) is provided on the outer periphery of the cork pad 21.

[0037] Through the design of the gap layer 24, amateur players can inject fillers of different materials or densities (such as gases, liquids, or solid materials with specific hardness) into the gap layer 24 according to their own training stages or game needs, so as to quickly adjust the hardness of the table tennis racket, improve the flexibility and adaptability of the table tennis racket, meet diverse usage requirements without frequently replacing the patches, improve the convenience of the table tennis racket, and reduce the economic burden on amateur players.

[0038] The embodiments of the present invention are given for the purpose of illustration and description. Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and should not be construed as limitations on the present invention. Those of ordinary skill in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
