Abstract

The utility model relates to a device for adding rubber and sponge elasticity for ping-pong rackets, which is characterized in that the device is a hermetic container containing ping-pong rackets or a rubber and sponge of ping-pong rackets, the hermetic container is a hermetic bag with a locking seal assembly, the hermetic bag is arranged with an opening for putting the ping-pong rackets or rubber and sponge of ping-pong rackets in. The locking seal assembly, via the locking seal of the opening of the hermetic bag, forms an inner hermetic cavity for housing the ping-pong rackets or rubber and sponge of ping-pong rackets. With simple structure and small size, the utility model can be curled and folded for storage and is convenient to carry; additionally, the device is resistant to a pressure and can be conveniently pressurized by an inflation valve; furthermore, the utility model has the advantages of favorable air-tightness and convenient usage but has no harm to people health. After being pressurized storage, the pressure of the tiny air chambers of the rubber and sponge of the rackets is increased, which can greatly raise the elasticity of the ping-pong rackets and improves the competitive performance of athletes.

Description

A kind of increase rubber on table tennis bat and the flexible device of sponge
Technical field
The utility model relates to a kind of device that increases elasticity of table tennis bat, especially a kind of increase rubber on table tennis bat and the flexible device of sponge.
Background technology
General table tennis bat comprises the racket plate and covers its surperficial rubber and sponge.From International Table Tennis Federation be defined in use the big table tennis that diameter is 40mm in the regulation game instead after, big table tennis has significant change on parameters such as elasticity, speed, rotation, volume and weight.For increasing the elasticity of table tennis bat, improve athletic competitiveness, people update the structure of racket plate and develop new material the elasticity of rubber and sponge is improved; What is more adopts the mode of encapsulating, utilizes the volatility of organic glue to be expanded in the stingy chamber in rubber and the sponge, to reach the purpose that increases suppleness of bat.But preceding kind of method cost is bigger, and the technological requirement complexity; Harmful violated solvent often is limited to use back kind method because of glue contains usually.
Summary of the invention
The purpose of this utility model is to provide a kind of simple in structure, easy to use and harmless can increase rubber on table tennis bat and the flexible device of sponge.
For achieving the above object, the utility model is by the following technical solutions:
A kind of increase rubber on table tennis bat and the flexible device of sponge, it is characterized in that: this device is the airtight container that holds table tennis bat or rubber on table tennis bat and sponge, described airtight container is a sealing bag that closes black box with lock, the sealing bag is provided with the oral area that can supply table tennis bat or rubber on table tennis bat and sponge to insert, and sealed black box is by holding the closed cavity of table tennis bat or rubber on table tennis bat and sponge to the sealed sealing formation one of sealing bag oral area.
During use, table tennis bat is put into sealing bag, pressurization is preserved.In addition, also can only rubber and sponge be put into bag pressurization preservation, take out before using, stick on the racket plate.
Technique scheme can also be further improved by following technical measures:
Described airtight container internal pressure value is 0.2--0.5MPa.After the rubber of racket and sponge preserved under this air pressure, elasticity obviously strengthened.
Described sealing bag is provided with the valve cock that communicates with closed cavity.
Described sealed black box comprises airtight pressing plate and following airtight pressing plate, go up airtight pressing plate and be respectively equipped with through hole and bolt with following airtight pressing plate corresponding position, bolt passes from through hole and is furnished with nut, and upper and lower airtight pressing plate compresses the oral area of sealing bag by bolt and nut and closes up.
The oral area of described sealing bag and bolt corresponding position are provided with the circular hole that passes for bolt.
Described airtight pressing plate or down airtight pressing plate mutually pressure surface is provided with sealing strip, sealing strip is made by foam or plastics elastomeric material.
The utility model is simple in structure, and it is little to take up room, and the stored collapsed of can curling is easy to carry; Next is that this device is withstand voltage reliable, and is convenient by the valve cock pressurization; Once more, the utility model air-tightness is good, and is easy to use and harmless, and racket is after the pressurization storage, and stingy chamber air pressure increases in rubber and the sponge, can improve the elasticity of table tennis bat greatly, improves athletic competitiveness.
Description of drawings
