Abstract

The invention discloses a silicone rubber ball nozzle comprising a ball body and a bulblet. The bulblet is made of silicone rubber and is of a cylindrical structure. The ball body is made of natural rubber and composed of an inner ball body and an outer ball body. The ball body is embedded at a liner. The inner ball body is tightly attached to the inner side of the liner, and the outer ball body is tightly attached to the outer side of the liner. According to the silicone rubber ball nozzle, the bulblet is made of the silicone rubber, the silicone rubber is high in density, abrasion resistance and high-and-low-temperature resistance, and the silicone rubber still has the elasticity and can be normally used in the environment at the temperature of -30 DEG C to 50 DEG C; in use, the ball nozzle will not be damaged when a metal inflation needle is inserted in and pulled out, and therefore the silicone rubber ball nozzle is long in service life and durable; the bulblet is of the cylindrical structure, tightly combined with the ball body and quite convenient to install; through a zigzag structure, it is guaranteed that the bulblet is fixed well.

Description

technical field [0001] The invention relates to a ball mouth, in particular to a silicon rubber ball mouth, and belongs to the technical field of inflatable balls. Background technique [0002] The three major balls of football, volleyball and basketball are all composed of ball pieces, liners and ball mouths. According to different manufacturing methods, they can be divided into adhesive balls, stitched balls and rubber balls; whether it is adhesive balls or stitched balls Or rubber balls, all need to use liner when making, and ball mouth is set on the liner; The liner connection of existing liner is not firm, easy to leak; The ball mouth is made of natural rubber material or neoprene material, time It is easy to deform, harden, and crack when it grows; in addition, every time you inflate, the metal inflation needle is inserted and pulled out of the inflation hole of the ball nozzle, which will cause certain damage to the inflation hole of the ball nozzle. After a long time...
