Description

Technical Field

[0001] The present invention relates to the field of table tennis racket technology, and particularly to a green glue-free table tennis racket. Background Art

[0002] A table tennis racket consists of three parts: a bottom plate, a rubber sheet, and a sponge. The reasonable combination of the three determines the quality of a racket. The rubber sheet is usually adhered and fixed to the bottom plate with glue. Glue can be divided into organic glue and inorganic glue. Organic glue contains substances harmful to human health, such as formaldehyde. Inorganic glue has a higher viscosity and a slower drying time compared to organic glue. Therefore, the replacement time of the rubber sheet is longer, and it is troublesome to clean inorganic glue, so it needs to be handled with extra care when using. Summary of the Invention

[0003] To solve the above problems, the present invention discloses a green glue-free table tennis racket, which includes a bottom plate. Both sides of the bottom plate are fixedly connected with adhesion plates. A groove is sunken in the middle of the adhesion plate, and a rubber sheet is cooperatively arranged in the groove. That is, the lower part of the rubber sheet is covered and fixed on the adhesion plate, and the use of glue can be avoided.

[0004] The side wall of the groove of the adhesion plate is inclined, and the side of the rubber sheet is inclined, and they are cooperatively arranged in the groove with an anti-detachment inclination angle. That is, the convex edge at the edge of the adhesion plate has a larger upper size and a smaller lower size, and the outer side wall of the convex plate is vertical. Through this structure, the adhesion effect of the rubber sheet is further improved.

[0005] Preferably, the rubber sheet includes a silica gel coating on the lowermost layer. The bottom wall of the groove of the adhesion plate is smooth, and the silica gel coating is cooperatively arranged on the bottom wall of the groove. The purpose of setting the silica gel coating is to make the rubber sheet adhere to the adhesion plate by using the intermolecular force, so that the adhesion effect of the rubber sheet can be achieved without using glue.

[0006] Preferably, the rubber sheet includes a rubber layer. A sponge layer is arranged below the rubber layer, and a film layer is arranged below the sponge layer. The silica gel coating is applied on the film layer. The film layer is used for sealing to prevent the gas in the sponge layer from entering the space where the silica gel coating is located and reducing the effect of intermolecular force.

[0007] Preferably, a plurality of through holes are arranged on the edge of the racket, and a fixing buckle structure is arranged in the through holes. The fixing buckle structure includes a plug and a buckle ring. The plug and the buckle ring are in interference fit to clamp the rubber sheets on both sides. The rubber sheets are further fixed, and at the same time, the fixing buckle structure is placed on the edge of the racket to reduce the influence on hitting the ball.

[0008] Preferably, gaskets are arranged at one ends of the plug and the buckle ring respectively. This makes the rubber sheet flat and improves the aesthetics of the racket.

[0009] Preferably, a handle is arranged on the bottom plate.

[0010] The beneficial effects of the present invention are as follows:

[0011] 1. An adhesion plate is added, and the structure of the rubber sheet is optimized, that is, a thin film layer and a silica gel coating are added. Combined with the inclined setting of the edge of the film, the rubber sheet can be tightly attached to the adhesion plate without using glue, which has the advantage of being green and environmentally friendly.

[0012] 2. With this structure, the replacement of the rubber sheet is similar to applying a mobile phone film, which has the advantages of convenience and speed. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further clarified below in conjunction with the drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and not to limit the scope of the present invention. It should be noted that the terms "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the terms "inner" and "outer" respectively refer to the directions towards or away from the geometric center of a specific component.

[0022] Combined with Figure 1 and Figure 2As shown, a green glue-free table tennis racket includes a bottom plate 2, which is a solid wood board instead of an artificial board to achieve the purpose of green environmental protection. Adhesion plates 4 are fixedly connected to both sides of the bottom plate 2. The adhesion plates 4 are a plastic plate and can be fixedly connected to the bottom plate 2 by thermoplastic one-piece molding. The bottom plates are placed together in a mold for injection molding. A groove is set in the middle of the adhesion plate 4, and a rubber 3 is matched in the groove, that is, the lower part of the rubber 3 is accommodated in the groove.

[0023] Combination Figure 4 and Figure 5 As shown, the side wall of the groove of the adhesive plate 4 is inclined, the side edge of the rubber 3 is inclined, and is fitted in the groove at an anti-slip angle, that is, the lower end size of the rubber 3 is larger than the upper end size, and the inclination angle of the side wall of the groove and the inclination angle of the side edge of the rubber 3 are both α, and α is an acute angle, preferably 45°.

[0024] The rubber 3 includes a bottom layer of silicone coating 31, the bottom wall of the groove of the adhesive plate 4 is smoothly arranged, and the silicone coating 31 is matched on the bottom wall of the groove, that is, the rubber 3 is adhered to the adhesive plate 4 by molecular force.

[0025] Furthermore, when replacing and installing the rubber 3, it is necessary to wipe the bottom wall of the groove of the adhesive plate 4 clean, and then attach the rubber 3 to the groove, and the lower part of the rubber 3 is received in the groove, and then use a rolling type tool to roll one side of the rubber 3 to completely expel the air between the two. The process is similar to that of applying a film to a mobile phone.

[0026] like Figure 4 As shown, the rubber 3 includes a rubber layer 34, a sponge layer 33 is arranged below the rubber layer 34, and both the rubber layer 34 and the sponge layer 33 are of conventional structure. A film layer 32 is arranged below the sponge layer 33, and a silicone coating 31 is coated on the film layer 32. The film layer 32 is used for sealing to prevent the air in the sponge layer 33 from entering the silicone coating 31, thereby reducing the molecular force.

When replacing the rubber 3, a thin rod is used to support one end of the latch 6 in advance and press it out. After the rubber 3 is finished, the latch 6 and the buckle ring 7 are replaced and installed. The use of the latch 6 and the buckle ring 7 further improves the effect of the attachment and fixing of the rubber 3.

[0028] One end of the latch pin 6 and the buckle ring 7 is provided with a sealing pad 5. It is used to improve the aesthetics of the racket and reduce the impact on the ball.

[0029] A handle 1 is provided on the bottom plate 2 .
