Description

Ball inner container with double ball head structure and indoor ball thereof

Technical Field

The utility model relates to a ball inner bag for sports, specific ball inner bag of double-ball-head structure that says so belongs to rubber ball technical field.

Background

Sports balls generally include an outer casing and an inner bladder disposed within the outer casing. The ball head and the ball are arranged on the inner container, and the ball inner container can be repeatedly inflated and deflated. The inner container in the prior art is made of rubber materials through a high-temperature vulcanizing and curing mode. The inner wall and the outer wall of the inner container are smooth except for the exhaust lines, and the surface layer is also provided with stripes specially used for attaching woven fabrics or leather materials and the like.

For some ball inner containers of indoor balls needing fillers inside at present, materials such as silk floss and the like need to be filled into the ball inner containers through the cut after the ball inner containers are manufactured so as to reduce the elasticity of the balls, but the final sealing process adopting the working procedure not only influences the air tightness of final products, but also greatly improves the labor and manufacturing cost. The traditional single ball head design still has problems in the stability of ball operation.

SUMMERY OF THE UTILITY MODEL

The utility model aims to solve the technical problem that, overcome prior art's shortcoming, provide a ball inner bag of two bulb structures, through the adjustment to the ball inner bag structure, improve the defect that the ball inner bag exists in the manufacturing process, improve spheroid operation stationarity to reduce simultaneously and make and cost of labor.

In order to solve the technical problem, the utility model provides a ball liner with double ball head structure, which comprises a ball liner blank made of rubber, wherein the ball liner blank is provided with at least one pair of symmetrical through holes, one of the through holes is provided with an inflation ball head, and the other through hole is provided with a filling ball head; an inflation ball is filled in the inflation ball head, and a solid ball is filled in the filling ball head.

The utility model discloses a further inject technical scheme, aforementioned double-bulb structure ball inner bag, just it is the same with packing the bulb to aerify the bulb, and the same bulb of aerifing gives the bladder with packing the bulb and provides the counter weight, makes the ball can fly stably when using, improves the experience sense of using.

Aforementioned double-bulb structure ball inner bag, aerify the bulb and fill the bulb and all have the arc bonding sheet that matches with the laminating of ball courage blank inner wall, improve the connection effect of bulb and ball courage, guarantee the sealed effect of through-hole behind the installation bulb, effectively prevent the possibility that gas leakage from appearing in bulb connection installation department.

According to the ball inner container with the double-ball-head structure, the anti-blocking filter unit is arranged at the port of the inflatable ball head inside the ball blank, and after the filler is filled in the ball inner container, when the ball inner container is inflated and deflated, the risk of blocking caused by the filler on the ball head can be effectively reduced.

Aforementioned double-bulb structure ball inner bag, the through-hole of packing the bulb is greater than aerify the through-hole of bulb, make things convenient for the packing of later stage packing and the installation of packing the bulb, improve the convenience of ball inner bag processing.

Further, this application still provides an indoor ball, including ball inner bag, filler and spheroid crust, the ball inner bag adopts as aforementioned first ball inner bag of two bulb structures the intussuseption of ball inner bag is filled and is reduced elastic filler, the cladding of spheroid crust is in the ball inner bag outside.

The utility model has the advantages that: the utility model discloses an improvement to traditional ball bladder structure, change traditional unilateral ball head structure's ball inner bag into the ball inner bag of two side ball head structures, make things convenient for the ball inner bag to carry out filling of filler, it is balanced simultaneously through the configuration of both sides bulb, can also improve the steady of sports ball flight when using that this kind of ball bladder made, the two bulb structures of reasonable use, not only can guarantee spheroidal stability, can also promote the off-the-shelf yields of ball bladder, finally and reduce manufacturing and cost of labor by a wide margin.

Detailed Description

Example 1

The embodiment provides a ball liner with a double-ball-head structure, which is structurally shown in fig. 1 and fig. 2 and comprises a liner blank 1 made of rubber, wherein the liner blank is provided with a pair of symmetrical through holes, an inflatable ball head 2 is arranged at one through hole, a filling ball head 3 is arranged at the other through hole, and the through hole for installing the filling ball head is larger than the through hole for installing the inflatable ball head; an inflatable ball is filled in the inflatable ball head, and a solid ball is filled in the inflatable ball head; the inflation ball head and the filling ball head are the same and are both provided with arc-shaped bonding sheets 4 which are attached and matched with the inner wall of the bladder blank. The ball head that aerifys is equipped with at the inside port of bladder blank and prevents stifled filter unit 5, and after the bladder intussuseption was filled and is reduced elastic filler, when filling the gassing to the bladder, prevent stifled filter unit's filter media and can effectively reduce the filler and cause the risk of jam to the ball head.

Example 2

The embodiment discloses an indoor ball, which comprises a ball inner container, fillers and a ball outer skin, wherein the ball inner container is of a double-ball-head structure as in embodiment 1, the fillers made of silk floss are filled in the ball inner container, and the ball outer skin is coated on the outer side of the ball inner container.

The bladder of this embodiment has made things convenient for the filling operation of bladder through the setting of double-end structure, has promoted the maneuverability of bladder when filling to double-bulb structure can reach the balanced purpose of bladder counter weight, makes the ball more steady in the use operation, has improved the flight stability of ball.

In addition to the above embodiments, the present invention may have other embodiments. All the technical solutions formed by adopting equivalent substitutions or equivalent transformations fall within the protection scope claimed by the present invention.
