Through above-mentioned technical scheme, set up the rubber projection on the cavity inner wall and play the effect that increases this cricket and replace ball weight, make cricket replace ball weight more closely match with cricket's weight for the training has more the effect.

Preferably, the exterior of the rubber sphere is coated with an acrylic waterproof coating.

Through the technical scheme, the acrylic waterproof layer coated on the outer surface of the rubber ball body ensures that water is not easy to remain on the surface of the rubber ball body and the rubber ball body is not easy to mildew or crack.

Preferably, a chlorosulfonated polyethylene anti-aging coating is arranged between the rubber ball and the acrylic acid waterproof coating.

Through the technical scheme, the chlorosulfonated polyethylene anti-aging coating coated on the surface of the rubber sphere enables the rubber sphere not to be easy to age and crack.

Preferably, a through hole for installing the inflating nozzle is formed in the rubber ball body, the inflating nozzle is accommodated in the through hole, and a plug for covering the through hole is arranged at the orifice of the through hole.

Through above-mentioned technical scheme, use the end cap to cover the drill way of through-hole for during external dust and impurity are difficult for entering into the charging connector, guarantee that the charging connector can normal use.

Detailed Description

The following detailed description of the embodiments of the present invention is made with reference to the accompanying drawings, so that the technical solution of the present invention can be more easily understood and grasped.

A cricket replacing ball is shown in figure 1 and comprises a rubber ball body 1, wherein the rubber ball body 1 is made of rubber, and the rubber is a high-elasticity polymer material with reversible deformation and is high in elasticity. When the cricket replacing ball is used, even if the cricket replacing ball is hit on the body of a practicer, overlarge damage can not be caused, so that the use safety of the cricket replacing ball is greatly improved, and the potential safety hazard when the cricket replacing ball is used is greatly reduced.

As shown in fig. 1 and 3, a cavity 2 is arranged inside the rubber ball 1, a plurality of rubber studs 6 are uniformly distributed on the inner wall of the cavity 2, the plurality of rubber studs 6 and the rubber ball 1 are integrally formed, and the end portions of the plurality of rubber studs 6 all point to one side of the center of the rubber ball 1. The rubber convex columns 6 are used for increasing the quality of replacing cricket balls by cricket balls, so that the cricket balls are closer to the weight of cricket balls for competition, and a better training effect can be obtained.

A through hole 9 communicated with the cavity 2 is formed on the rubber ball body 1, and the inflating nozzle 3 is arranged inside the through hole 9. When the cricket replacement ball needs to be inflated, the air core on the inflating device is inserted into the inflating nozzle 3, so that the inflating nozzle 3 is in an opening state, then the inflating device is opened to inflate the cavity 2, so that the air pressure inside the cricket replacement ball is increased, and the elasticity of the cricket replacement ball is increased. When the inflation is completed, the air core is pulled out from the inflating nozzle 3, at the moment, the inflating nozzle 3 is closed, and the air in the cavity 2 cannot be discharged to the outside through the inflating nozzle 3. When needing to replace and replace ball to cricket and deflating, only need insert the gas core inside charging connector 3 for charging connector 3 is in the open mode, and the inside air of cavity 2 can be discharged to the external world through charging connector 3 this moment, makes the cricket replace the inside atmospheric pressure reduction with the ball, and the cricket replaces the elasticity of ball and can weaken.

The orifice of the through hole 9 is provided with a plug 10, and the plug 10 plugs the orifice of the through hole 9, so that external dust and impurities are not easy to enter the charging connector 3 and influence the normal use of the charging connector 3.
