Abstract

The utility model closes a sports gas-filled ball, whose structure has one more layer of airtight obstructing material than that of the traditional ball. The additional layer is arranged between an inner liner and a layer of friction spun yam. The obstructing material is balloon and plastics which are vulcanized into a sealed glue layer, which can obstruct effectively the loss of the air inside the ball, so that the air-pressure inside the ball can be stabilized in a long term.

Description

A kind of inflatable ball

Affiliated technical field

The utility model relates to a kind of motion inflatable ball, belongs to the athletic sports appliance technical field.

Background technology

Existing motion inflatable ball major part is, comprise an inflatable inner bag from inside to outside successively, one twines the layer that twines of inner bag outside, one centers on plies in the rubber that twines the layer outside, and being covered on the exodermis of outer casing in the rubber, but the poor air-tightness of its inner bag and whole ball can not keep the inner liner pressure of inflatable ball for a long time, need often inflation, very inconvenient.

Summary of the invention

The utility model purpose is to provide a kind of motion inflatable ball, and the air pressure of the inner bag of motion inflatable ball is stablized for a long time, effectively intercepts the gas loss of the inner bag of motion inflatable ball.

For achieving the above object,, provide a kind of motion inflatable ball according to the technical solution adopted in the utility model.Can comprise an inflatable inner bag from inside to outside successively, one twines the layer that twines of inner bag outside, one centers on plies in the rubber that twines the layer outside, and be covered on the exodermis of outer casing in the rubber, in the inner bag of ball and twine layer or layer of cloth between set up one deck barrier, this barrier is balloon, plastics, is sulfided into sealant layer.

The beneficial effects of the utility model are: adopt the motion inflatable ball of this structure, than the structure one deck of manying air-tightness barrier of traditional ball, the air that this barrier can effectively intercept in the spheroid runs off, thereby stablizes the gas pressure in the spheroid for a long time.

Description of drawings

The utility model is described in further detail below in conjunction with drawings and Examples.

Fig. 1 is traditional ball section of structure;

Fig. 2 is the utility model section of structure.

The specific embodiment

As shown in Figure 1 and Figure 2, traditional ball structure is cutd open, be followed successively by from inside to outside to comprise an inflatable inner bag (1), one twine the inner bag outside twine layer (2), one in the rubber that twines the layer outside plies (3), and be covered on the exodermis (4) of outer casing in the rubber.Patent of the present invention is, at the inner bag (1) of traditional inflatable ball ball and twine and increase one deck air-tightness barrier (5) between the layer (2), strengthens the gas leak preventing effect.This motion inflatable ball, can comprise an inflatable inner bag (1) from inside to outside successively, one twine the inner bag outside twine layer (2), one centers on plies (3) in the rubber that twines the layer outside, and be covered on the exodermis (4) of outer casing in the rubber, in the inner bag of ball and twine and set up one deck barrier (5) between the layer, barrier is balloon, plastics, is sulfided into sealant layer (5).

Adopt the motion inflatable ball of this structure, comprise basketball, vollyball, football, rugby etc., than the structure one deck of manying air-tightness barrier of traditional ball, the air that this barrier can effectively intercept in the spheroid runs off, thereby stablizes the gas pressure in the spheroid for a long time.

Claims (2)

1. inflatable ball, can comprise an inflatable inner bag from inside to outside successively, one twines the layer that twines of inner bag outside, and one centers on plies in the rubber that twines the layer outside, and be covered on the exodermis of outer casing in the rubber, it is characterized in that: in the inner bag of ball and twine and set up one deck barrier between the layer.

2. a kind of inflatable ball according to claim 1 is characterized in that: described one deck barrier is balloon, plastics, is sulfided into sealant layer.
