Problems solved by technology

[0003] In addition, the bottom plates of table tennis rackets in the prior art mostly adopt a solid structure, which makes the overall weight of the table tennis racket heavier, which affects the strength of athletes or table tennis fans when they play.
In addition, although the surface of most table tennis rackets is also made of thermoplastic soft rubber (TPR), most of them are designed with a smooth surface, which cannot effectively increase the friction and rotation speed when hitting the ball, so it is not an ideal plastic table tennis racket.

Embodiment 1

[0035] 1. Specific preparation of raw materials and ratio

[0036] Improved table tennis racket of the present invention, its bottom plate 1 comprises preparation raw material according to weight proportion:

[0037] Modified polypropylene is 85 parts; glass fiber is 14 parts; azodicarbonamide is 0.25 parts; phthalate is 0.5 parts; carbon black is 0.15 parts.

[0038] 2. Preparation method

[0039] The preparation method of the bottom plate 1 of the improved table tennis racket of this embodiment is to use modified polypropylene (CSR-6000G115) as the main material, glass fiber is used as traction, azodicarbonamide is used for foaming, and phthalate Enhanced plasticity, plus carbon black for coloring.

[0040] It specifically includes the following steps: 1), pretreatment: before plasticizing, the modified polypropylene is dried for 6-8 hours, and the temperature range is controlled at 70-80°C during drying; the function of this step is to eliminate the modified polypropylene...

Embodiment 2

[0045] Such as Figure 1-4As shown, the improved table tennis racket of the present invention includes a base plate 1, an elastic panel 2 and a handle 3 positioned on the base plate 1, and the base plate 1 includes a first plane 11 parallel to each other, a second plane 12 and a first plane 12 for connecting the first The outer facade 13 of the plane 11 and the second plane 12, the outer facade 13 is provided with several blind holes 14 extending to the inside of the bottom plate 1, and ribs 15 are formed between adjacent blind holes 14; the inner bottom plate 1 A main rib 16 is arranged along the axial direction of the handle 3, and the ribs 15 and the main rib 16 are connected as an integral structure, and they serve as important bearing force positions for table tennis rackets. As a specific embodiment, the ribs 15 and the main ribs 16 jointly form a fishbone structure. Of course, another situation is also allowed, the main rib 16 is located at the center of the bottom pla...

Embodiment 3

[0049] Such as Figure 5-7 As shown, in order to enhance the adhesion between the racket bottom plate 1 and the elastic panel 2, the bottom plate 1 is provided with a number of evenly arranged concave holes 17, and the concave holes 17 are attached to the elastic panel 2 together. The elastic panel 2 and the handle surface 34 of the present invention are all made of TPR (thermoplastic rubber material) material, through the secondary processing of the abrasive tool, the concave holes 17 are filled with TPR material, so that the elastic panel 2 and the racket bottom plate 1 Combine more closely. Another important improvement point of the present invention: the elastic panel 2 can also be provided with several concave holes 17 arranged evenly. In addition to enhancing the combination of the racket bottom plate 1 and the elastic panel 2, the concave hole 17, please refer to Figure 6 . More importantly, it can effectively improve the friction, rotation speed and rebound speed g...

Abstract

The invention discloses a bottom plate of an improved table tennis bat and the table tennis bat. The bottom plate of the improved table tennis bat adopts a special material, so that the table tennis bat is impact-resistant, ageing-resistant and better in rigidity; the bottom plate of the improved table tennis bat adopts a fish bone structure to realize the partially hollow effect of the bat bottom plate, and the whole weight of the table tennis bat is reduced; a plurality of concave holes are uniformly distributed in an elastic bottom panel and the bottom plate of the table tennis bat, the contact surface between the table tennis bat and a table tennis is enlarged by the concave hole structure, and most important, the friction and the rotating speed which are produced by the bat to the table tennis when the table tennis is hit in the table tennis sport are improved.

Description

technical field [0001] The invention belongs to the field of sports equipment, and in particular relates to an improved bottom plate of a table tennis racket and the table tennis racket. Background technique [0002] There are roughly three types of bottom plates for table tennis rackets: pure wood, carbon and crystal coating. The pure wood racket bottom plate is better to exert force, and the control is relatively stable, but it wastes forest resources and the production efficiency is low. With the extension of use time, the wooden bottom plate is easy to be separated from the elastic panel; the carbon racket bottom plate has better elasticity. However, the vibration is large, the control is difficult, and the ball is not good; the crystal-coated soleplate is between the two, and the control feeling is slightly worse than that of pure wood. With the development of table tennis racket production technology, plastic table tennis rackets have been produced in the prior art. T...
