Abstract

The utility model relates to a sporting ball, and provides an improved softball. The sporting ball contains a ball center made of soft wood, rubber or PU materials and a ball skin structure made of leather, and is characterized in that an improved spinning yarn layer obtained by immersing a layer of polymer resin materials is added between the ball center and ball skin. The improved baseball has the main advantages that because the improved spinning yarn layer is more flexible than the original strophism materials and the weight has little change, the obtained improved baseball not only can perform the function of separating various liquid but also has durableness, stable anti-elasticity, hardness-softness and structure, long service life, and is close to the traditional baseball standard; the integral physical property of the baseball is better.

Description

The softball of improved characteristics

Technical field

The utility model relates to a kind of ball for sports, relates in particular to a kind of each class I liquid I, durability of isolating, bounce-back property, keep internal structure more stable, longer service life, more approaching tradition match softball physical characteristic standard, the softball of the improved characteristics that whole physical property maintenance is better.

Background technology

The structure of softball has following two kinds at present: a kind of is the centre of sphere of being made by cork 4, and thread layers 5 in the winding, and after the gluing, wrapping had both become complete softball after leather football shirt 6 needlework are sewed up; A kind of is the centre of sphere of being made by rubber or PU 7, winding yarn not, and directly gluing, wrapping had then both become complete softball after leather football shirt 8 needlework are sewed up.For first kind of softball, as everyone knows, cork and common yarn layer all are to have certain hygroscopic material, in case when being used in this kind softball in the higher regional or rainy environment of humidity, the cork centre of sphere and common yarn layer will make spheroid weight increase because of having stronger hygroscopicity, and then influence the rebound coefficient of ball, in addition, after sucking aqueous vapor, must cause the inner cork springy texture of the centre of sphere, the yarn fragile easy fracture that also becomes, the centre of sphere is deformed, thread layers tearing can't keep original physical characteristics, greatly reduces the service life of softball.For second kind of softball, make the softball of the centre of sphere by rubber or PU material, though rubber or PU material do not absorb water basically, but because it is little to be used to make the rubber or the PU density of material of the softball centre of sphere, inside is fluffy structure, make its inner very many capillary space that distributes, the existence of capillary space has caused the centre of sphere still to have certain moisture.The weight of softball equally also can be because of the suction of spheroid, moisture absorption and is changed, and has influenced the physical characteristic of softball; Simultaneously, in impacting process, because the energy conversion can make the sphere volume amount of stored heat, the variation of high-temperature makes rubber or PU aging easily, and its to lack the common yarn layer firm, reduced the stability of softball to a certain extent, thereby influenced the physical characteristic of softball.

The utility model content

The utility model is to provide a kind of softball of improved characteristics, can isolate each class I liquid I to solve, and durability, keeps internal structure more stable at bounce-back property, longer service life, more approaching traditional softball standard, the technical problem that whole physical property is better.

The utility model will solve the problems of the technologies described above the softball that the technical scheme that is adopted is achieved in that a kind of improved characteristics, contain cork, rubber or the PU material centre of sphere, the football shirt structure that leather is made is characterized in that: add between the centre of sphere and football shirt that last layer has soaked fluoropolymer resin class material (Polymer Resin) and the yarn layer of the improved characteristics that obtains.The yarn layer soaks fluoropolymer resin class material (Polymer Resin), behind the fluoropolymer resin class material (Polymer Resin), through permeate → absorb → form a globality structure from skinning with the yarn layer after condensing, promptly obtain the yarn layer of improved characteristics.The anti-yarn of improved characteristics is coated on the outside of cork, rubber or the PU material centre of sphere, with glue with itself and the football shirt formation softball that bonds together.

Major advantage of the present utility model is: because of the spinning layer of improved characteristics has more suppleness than original prehensile material, and weight does not have great changes, the softball of the improved characteristics that obtains can not only play isolates all kinds of liquid effects, and have more durability, and bounce-back property, soft durometer and structure are more stable, longer service life, more approaching traditional softball standard makes the whole physical property of softball better.

The specific embodiment

In order further to understand structural feature of the present utility model, hereinafter with reference to accompanying drawing specific embodiment of the utility model is further described, description is described as follows:

Referring to Fig. 3, a kind of softball of improved characteristics, contain cork, rubber or the PU material centre of sphere 1, football shirt 2 structures that leather is made is characterized in that: add between the centre of sphere and football shirt that last layer has soaked fluoropolymer resin class material (Polymer Resin) and the yarn layer 3 of the improved characteristics that obtains.After the yarn layer soaks fluoropolymer resin class material (Polymer Resin), fluoropolymer resin class material (Polymer Resin) through permeate → absorb → form a globality structure from skinning with the yarn layer after condensing, promptly obtain the yarn layer of improved characteristics.The anti-yarn of improved characteristics is coated on the outside of cork, rubber or the PU material centre of sphere, with glue with itself and the football shirt formation softball that bonds together.

The above, be the utility model one preferable possible embodiments only, when the scope that can not promptly limit the utility model embodiment with this, the equalization of being done according to the utility model claim changes and modifies such as, all should still belong in the scope that this case contains, give statement earlier in this.

Claims (1)

1, a kind of softball of improved characteristics, contain cork, rubber or the PU material centre of sphere (1), the football shirt that leather is made (2) structure is characterized in that: add between the centre of sphere and football shirt that last layer has soaked fluoropolymer resin class material and the yarn layer (3) of the improved characteristics that obtains.
