Description

Basketball

Technical field

The present invention relates to sports goods technical fields, more particularly, to a kind of basketball.

Background technique

Common basketball, from the inside to the outside successively include rubber inner layer, winding layer, PU outer layer, and be additionally provided on the ontology into Gas nozzle.Wherein, the quantity and quality that twine yarn directly affect the quality of basketball.For example, twine yarn is less, twine yarn not enough uniformly, It is poor with yarn quality, it can make basketball easily deformable then not round enough, finally affect feel, hit rate of basketball etc..

Summary of the invention

The object of the present invention is to provide a kind of basketballs, it has the characteristics that cost is relatively low, is unlikely to deform.

The technical scheme adopted by the invention is that: basketball, the ontology including basketball, the ontology successively include rubber from the inside to the outside Glue internal layer, winding layer, PU outer layer, and it is additionally provided with suction nozzle on the ontology,

It is described to be set inside the body a spherical and hollow plastic casing, it is uniformly distributed on the plastic casing several ventilative Hole, and be uniformly connected at least 6 connecting tubes, the outer end of connecting tube on the outer surface of the plastic casing and be uniformly connected to this On the inner surface of rubber inner layer, and the equal length of all connecting tubes in the ontology cavity radius and the plastic casing it is outer The difference of surface radius；

The suction nozzle is 2, and 2 suction nozzles are located at the surface and underface of the ontology, and suction nozzle passes through it In a connecting tube be connected to the inside of the plastic casing, the inner end opening of corresponding connecting tube is equipped with check valve.

Clinker Cowhells material layer and foamed cotton layer are additionally provided between the winding layer and PU outer layer from the inside to the outside.

The invention has the advantages that compared with the prior art: cost is relatively low, is unlikely to deform.Basketball of the invention passes through Several nylon ropes are set in inside, effectively reduce the probability of basketball deformation, without use it is more twine yarn, thus simultaneously Reduce material cost and preparation cost.

Detailed description of the invention

Present invention will be further explained below with reference to the attached drawings and examples:

Specific embodiment

Embodiment, as shown in Fig. 1 to Fig. 3: basketball, the ontology 10 including basketball.The ontology 10 successively includes from the inside to the outside Rubber inner layer 11, winding layer 12, PU outer layer 13.Winding layer 12 mostly uses nylon to carry out twining yarn.Air inlet is additionally provided on the ontology 10 Mouth 20.

Further say:

The inside of the ontology 10 is equipped with a spherical and hollow plastic casing 30.It is uniformly distributed on the plastic casing 30 several Air hole 31, and at least 6 connecting tubes 40 are uniformly connected on the outer surface of the plastic casing 30.For example, 6 connecting tubes 40 It is connected to surface, underface, front, the dead astern, front-left, front-right of the plastic casing 30.Connecting tube 40 1 As include internally positioned nylon tube and the plastic tube that is wrapped in outside nylon tube, to make it have enough pulling force and sealing Property is preferable.The outer end of connecting tube 40 is uniformly connected on the inner surface of the rubber inner layer 11, and the length of all connecting tubes 40 Degree is equal to the difference of the cavity radius of the ontology 10 and the appearance radius surface of the plastic casing 30.

Suction nozzle 20 is 2.2 suction nozzles 20 are located at the surface and underface of the ontology 10, and suction nozzle 20 The inside of the plastic casing 30 is connected to by a connecting tube 40 therein, the inner end opening of corresponding connecting tube 40 is set There is check valve 50.That is, the inside for being inflated to the plastic casing 30 then enters the inside of the sphere 10 when inflation.

In this way, the sphere is unlikely to deform under the pulling force effect of the more connecting tubes being uniformly arranged 40, it can be ensured that it is justified Shape then twines yarn without more, greatly reduces preparation and material cost.Meanwhile symmetrically arranged suction nozzle 20, and Inflation and inevitable chronic leakage carry out inside plastic casing 30, it is ensured that the stabilization of basketball center of gravity.

Optimization:

Clinker Cowhells material layer 14 and foamed cotton layer 15 are additionally provided between the winding layer 12 and PU outer layer 13 from the inside to the outside.In this way, making Feeling is better for basketball, and less easily-deformable.

The above description is only a preferred embodiment of the present invention, is not intended to limit the scope of the invention, all utilizations Equivalent structure or equivalent flow shift made by description of the invention and accompanying drawing content is applied directly or indirectly in other correlations Technical field, be included within the scope of the present invention.
