Abstract

The utility model relates to a high-grade inflating ball with a-shaped internal bladder for basketball, volleyball and football. The utility model is characterized in that a hollow internal bladder which is seamed according to ball shape by high intensity cloth such as canvas, nylon cloth, etc. is added between the external side of the inflating internal bladder and the inner side of the ball shell. The position of the-shaped internal bladder which is at the same axis with a gas nozzle and is symmetrical with the ball centre is pasted with a balance weight slice which has the same weight with the gas nozzle, and the outer surface of the inflating internal bladder is coated with a layer of leak proof seal gum. The high-grade inflating ball with a-shaped internal bladder for basketball, volleyball and football has the advantages of high intensity, difficult blowout, good air impermeability, balanced center of gravity and stable flying.

Description

The setting inner bag is senior ball

Affiliated technical field

The utility model relates to a kind of the hollow ball of inflatable bladder that have, the basket, row, the football that specifically promptly have inflatable bladder.

Background technology

Existing various basket, row, football all are provided with inflatable bladder, general inner bag is all made by rubber, its weak point be at first resilient rubber liner be subjected in inflation press and can infinitely expand and unsetting, outwards the power that expands directly acts on the spherical shell layer of outsourcing, spherical shell is popped, jointing line is exposed until the explosion that finally causes ball; The poor air-tightness of next rubber liner, the time one is long, and sufficient gas gradual slow leaks, and needs frequent supplemental inflation, use inconvenience; The gas that is rubber liner is once more chewed in a side, and gas is chewed and gas is bonded in the circle of one on the bladders around chewing and strengthens rubber layer, makes whole ball center of gravity chew a side at gas partially, makes the center of gravity imbalance of ball, and flight is unstable.

Summary of the invention

Arrange the deficiency of unsetting, the easy explosion of inflatable bladder, gas leakage and the crank etc. of football etc. for the hollow ball as basket that overcomes existing inflatable bladder, the utility model provides a kind of setting inner bag senior ball, make it be difficult for explosion, the time of keeping the gas abundance is long, the spheroid gravity balance, flight stability is good.

The technical scheme in the invention for solving the technical problem is: a kind of setting, inner bag are senior ballly to be made up of inflatable bladder outsourcing spherical shell etc., it is characterized in that setting up the spherical shape inner bag of a high strength between the inflatable bladder outside and spherical shell inboard, this inner bag is that high strength bottom weights such as canvas, nylon cloth are made by sphere; Add at the inflatable bladder outer surface and to scribble one deck leakproof seal glue; This setting inner bag and gas are chewed on the same axis with the symmetrical side of the centre of sphere and are pasted with weight stack, and this weight stack is coated with glue bond by abundant canvas or nylon cloth and makes, and its weight is chewed with gas and equated, what be affixed on the setting inner bag inboard or the outside chews the symmetry place with gas.

The utility model has the advantages that: the expansive force of inflatable bladder acts on the strong setting inner bag, and spherical shell is formalized is difficult for explosion, long service life after inner bag is protected; The weight stack of chewing the setting of symmetrical position with gas drops on the centre of sphere center of gravity of ball, and flight stability is good; The inflatable bladder air-tightness that appearance is coated with the last layer fluid sealant is good, do not have the phenomenon of slowly losing heart, behind the sufficient gas service time long, easy maintenance.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 is the utility model front view.1. gas are chewed among the figure, 2. fluid sealant coating, 3. inflatable bladder, 4. weight stack, 5. setting inner bag, 6. spherical shell.

The specific embodiment

In Fig. 1, between inflatable bladder (3) outside and spherical shell (6) inboard, set up high strength setting inner bag (5), on the symmetrical setting inner bag of the same axis of the centre of sphere, is furnished with weight stack (4) chewing (1) with gas, the outer surface of inflatable bladder (3) is coated with and is brushed with one deck leakproof seal glue-line, and the setting inner bag is made by sphere with abundant fabrics such as high strength canvas, nylon cloths.Weight stack is that a slice abundant one or more layers canvas, nylon cloth are coated with glue bond and make, and its weight is chewed with gas and equated.

Claims

1, a kind of have the senior ball of setting inner bag and be made of inflatable bladder outsourcing spherical shell etc., it is characterized in that setting up between the inflatable bladder outside and spherical shell inboard the high strength inner bag that formalizes.

2, setting inner bag according to claim 1 is senior ball, it is characterized in that described weight stack sticks on gas to chew a side symmetrical with the centre of sphere on the same axis.

3, setting inner bag according to claim 1 is senior ball, it is characterized in that being coated with at the inflatable bladder outer surface being brushed with one deck leakproof seal glue-line.

4, setting inner bag according to claim 1 is senior ball, it is characterized in that described setting inner bag made by sphere by abundant strong fabrics such as high strength canvas, nylon cloths.

5, setting inner bag according to claim 1 is senior ball, it is characterized in that described weight stack be one or more layers abundant canvas nylon cloth of a slice be coated with that glue bond makes chew equiponderant cloth sheet with gas or adhesive repeatedly applies the sheet adhesive that becomes to reach to need weight.
