Abstract

The utility model relates to a table tennis racket rubber characterized in the structure of centrally concave rubber particles. The top end of each rubber particle on the rubber is concave. The rubber with the structure of the rubber particles uses a centrally concave structure and the elastic deformation of elastic materials, and thereby, a negative pressure air chamber is generated at the top end of each of the rubber particles in the process of striking a table tennis ball, and positive pressure and friction force are increased for striking a ball. The problems which obsess people for a long time are solved, and friction force between a ball and the rubber is increased, wherein, the problems which obsess people for a long time refer to small friction force for a pimple in rubber and gradually reduced surface viscosity for a pimple out rubber.

Description

Rubber on table tennis bat with concave colloform

The utility model is the rubber on table tennis bat about a kind of colloform, a kind of rubber on table tennis bat that concave colloform is feature that has of more specifically saying so.

In table tennis, the effect of racket is most important, and it can directly have influence on athletic technology play and games results.For many years, along with the development of table tennis and constantly bringing forth new ideas of various technology play, table tennis bat is also constantly improving, and is photographed the racket that posts band micelle rubber by the hitting the ball with the wooden surface of the racket of beginning, increased spongy layer afterwards again, so that there is positive glueballs to clap and the bat of anti-glueballs now.To adapt to various play, no matter be positive glue or anti-glue, they all have a common purpose, utilize the high resiliency and the high friction property of rubber exactly, make the speed that hits ball fast, rotatory is strong, and it is more aggressive, positive glue be with micelle towards on be bonded on the racket sponge, anti-glue is micelle to be faced down be bonded on the racket sponge, rubber is made many micelles, and just to be attached to purpose on the racket be the rotatory that increases ball for the friction that improves square stance, general positive glue micelle is that the garden column type also has coarse numb line on the top of garden post, however the friction that positive glue is produced does not also reach requirement sometimes, thereby anti-glue appearred again, anti-glue characteristics aspect the friction that utilizes rubber are more outstanding, its reason is the promptly thin rubber layer that has viscosity again of surface table one deck of anti-glue rubber, the ball rotatory that hits with it is stronger, also just produced the technology play that lifts loop drive Just because of this, but anti-glue rubber also has its limitation, its tack retention hour of rubber layer that this exactly surface has viscosity is not very long, viscosity will weaken gradually expose a period of time in air after, this just gives and uses the previous generation to come inconvenience, as we understood in order to keep its viscosity, just often the sportsman is being bonded at new rubber on the racket before fast match.

Order of the present utility model ground is exactly to provide a kind of rubber on table tennis bat that had both had bigger friction and don't friction property is weakened gradually for solving above-mentioned deficiency to people, to solve the defective that little, the anti-glue surface viscosity of positive glue rubber frictional force weakens gradually.

The utility model provides a kind of rubber on table tennis bat with concave colloform, and the top of each micelle all is a spill on the rubber.Described female shapes can be hemispherical, triangle, trapezoidal.

We know, according to physics principle, and the size of the friction between two articles, constitute by two key elements, the one, the coefficient of friction between object, the one, the normal pressure between object, computing formula is that (F represents friction to F=μ N, μ represents coefficient of friction, and N represents normal pressure), coefficient of friction increases, friction also increases, the surface of anti-rubberizing skin made have bigger viscosity, just improved the coefficient of friction of body surface, thereby friction can improve also.According to above-mentioned physics principle, the raising of the friction between two articles is except that the coefficient of friction that improves object, and another key element is exactly the normal pressure that increases between object, this a kind of micelle with concave structure provided by the utility model just.Rely on the strain of rubber, make it in the batting process, ball (4) is with after micelle (5) contacts, air in the micelle center dant can be discharged, form a negative pressure chamber ground, the micelle that is contacted with ball is just as one by one little sucker, like this under the effect of external atmospheric pressure, make ball and micelle produce bigger normal pressure, correspondingly improved the friction between ball and the micelle.

The rubber on table tennis bat that the utility model provides with concave colloform, solved the problem that little, the anti-glue rubber of the positive glue frictional force surface viscosity that perplexs people for a long time weakens gradually, improve the friction between ball and rubber, reached the purpose of the rotary speed that improves the ball that hits.Simultaneously, come convenience for the use previous generation.

Below in conjunction with drawings and Examples the utility model is described further:

Fig. 1 is the partial sectional view after the rubber of the utility model colloform sticks into racket;

Fig. 2 is the racket batting Principle of Process figure of the utility model colloform.

Method according to common making rubber on table tennis bat, wherein make the mould of this rubber, its cope match-plate pattern all has a hemisphere that protrudes at corresponding each micelle capital end, corresponding with the middle template plate hole that forms the micelle post, make rubber (1) with concave semiglobe micelle (5) with this mould, method according to common making table tennis bat sponge, make table tennis sponge (2), method according to common making table tennis clappers, make table tennis bat clappers (3), rubber on table tennis bat, sponge, the clappers of concave structure micelle are pasted into complete table tennis bat.

Claims

1. rubber on table tennis bat with concave colloform, the top that it is characterized by each micelle on the rubber all is a spill.

2. as claims 1 described a kind of rubber on table tennis bat with concave colloform, it is characterized by described female shapes can be half garden shape, triangle, trapezoidal.
