Trampoline bamboo fiber table tennis racket bottom plate

Abstract

The invention relates to a bottom plate of a trampoline-type bamboo-weaving fiber table tennis bat, which is a composite plate synthesized by multi-layer materials. The bottom plate comprises a central thick plate layer provided with longitudinal texture natural woodiness and located in a center layer surface, thin plate layers with transverse texture natural woodiness are respectively fixed on the upper surface and the lower surface of the thick plate layer, the thick plate layer and the thin plate layers on the upper surface and the lower surface of the thick plate layer form a composite type core plate layer, penetrating holes are uniformly arranged on the composite type core plate layer, 1-4 natural bamboo-weaving fiber layers which are crisscross covered are respectively fixed on the upper surface and the lower surface of the composite type core plate layer with the penetrating holes, an upper panel and a lower panel with the longitudinal texture natural woodiness are respectively fixed on the outer surfaces of the upper bamboo-weaving fiber layer and the lower bamboo-weaving fiber layer, and a bat handle is provided with an inner core hollow cavity. The invention has the advantages of non-distortion, light weight, long service life, low cost, favorable ball control effect, powerful bounce, high batting speed and strong hitting effect, satisfies environmentally-friendly requirements, complies with the specifications of International Table Tennis Federation and is suitable for various playing methods, such as short court, middle court, quick attack, arc rotation, and the like.

Description

technical field [0001] The invention relates to a table tennis racket bottom plate, in particular to a trampoline table tennis racket bottom plate with a bamboo fiber structure inside. Background technique [0002] Table tennis has experienced more than a hundred years of development. During this period, changing the small ball to a large ball with a diameter of 40mm and implementing an 11-point scoring system are the most significant reforms. Due to the addition of a round of back-and-forth balls in the reform, it not only improves the stalemate of the confrontation between the players, makes the table tennis match more ornamental, but also promotes the marketization of table tennis. However, a racket with an all-wood base due to the reduction in ball speed and rotation has been brought along therewith, resulting in shortcomings such as inability to adapt, easy deformation, and short service life. Later, carbon, carbon fiber, carbon-aromatic mixed glass fiber, titanium all...

Problems solved by technology

[0004] The purpose of the present invention is to solve the practical problems of existing table tennis rackets such as easy deformation, short service life, high price of reinforcing materials such as carbon-aromatic mixed braided glass fibers, and no environmental protection, so as to provide a table tennis racket that is not easy in quality. Deformation, light weight, long service life, in line with environmental protection requirements, in terms of function, it has good ball control effect, strong rebound force, fast hitting speed, strong whipping effect, and is suitable for near table, middle table, fast attack, arc in operation Spin and other playing methods, the trampoline-style bamboo fiber table tennis racket bottom plate conforms to the regulations of the ITTF, and contributes to the improvement of the technical level of table tennis players
