Abstract

The utility model mainly provides a baseball with characteristics modified, which comprises a ball clothes structure made of a ball center which is formed by covering a plurality of layers of high-elastic rubber outside a high-density corkwood core, an accumulation layer formed by blending woolen yarn with various thickness, a yarn spinning layer and leather. The baseball with characteristics modified is characterized in that the yarn spinning layer is a composite layer, the outer surface of the yarn spinning layer of which is covered with a polymer resin layer. The polymer resin material (Polymer Resin) is soaked by the yarn spinning layer, the polymer resin material (Polymer Resin) self-skins on the outer surface of the spinning yarn after being soaked, absorbed and condensed, to form a polymer resin layer and then form a composite layer structure with the yarn spinning layer, the baseball with the modified characteristics has the advantages that compared with the original winding material, the composite layer structure has better flexibility, and the weight is not greatly changed, not only the baseball can take an effect of isolating various liquid, but also the baseball has better durability, and the counter-elasticity and the hardness and the softness are more stable, the service life is longer, and the baseball with characteristics modified is closer to the standard of the traditional baseball, thus the whole physical property of the baseball is better.

Description

The baseball of improved characteristics

Technical field

The utility model relates to a kind of medicine ball, relates in particular to a kind of each class I liquid I, durability of isolating, bounce-back property, soft durometer are more stable, longer service life, more approaching tradition match baseball physical characteristic standard, the baseball of the improved characteristics that whole physical property maintenance is better.

Background technology

The different formed lamination 2 of wool blend line of the centre of sphere 1, thickness that the used baseball of regulation game at present generally is made of the outer coating of high density cork nuclear several layers high elastic rubber, the football shirt 4 that common yarn layer 3 and leather are made is constituted.As everyone knows, be that Woolen yarn or thread layers all are the extremely strong fibrous materials of hygroscopicity, when making the lamination of baseball with these materials, in case when being used in this kind baseball in the higher regional or rainy environment of humidity, this lamination 2 makes spheroid weight increase because of having extremely strong water imbibition, and then influences the rebound coefficient of ball, causes the spheroid internal loose and deforms, can't keep the baseball original physical characteristics, greatly reduce the service life of baseball.Be to solve the baseball waterproof problem, occurred in the market a kind ofly on original traditional baseball basis, having made improved new baseball.This kind baseball is to add the made water barrier 5 of one deck plastics, rubber or other similar material between lamination and football shirt.Though this kind baseball can effectively intercept the infiltration of water liquid or aqueous vapor, can effectively solve waterproof problem, but after having added this layer watertight composition, making has increased plastics, rubber or other materials on the baseball, because the size of standard baseball and quality are relative fixed, increased other materials such as plastics, rubber again, internal structures such as the inner spiral of baseball, yarn will change to some extent, with the internal structure of traditional baseball gap are arranged; And baseball is after repeatedly hitting, the variations in temperature that spheroid produces through the repeated multiple times strike can make material aging, add this improvement and do not change the winding compactness of yarn, therefore make that baseball keeps that original physical characteristic is indeformable, there is no remarkable effect on the stability of bounce-back property and soft durometer.

The utility model content

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

The utility model will solve the problems of the technologies described above the baseball that the technical scheme that is adopted is achieved in that a kind of improved characteristics, contain by high density cork nuclear is outer and coat the football shirt structure that the different formed lamination of wool blend line, yarn layer and the leathers of the centre of sphere, thickness that the several layers high elastic rubber constituted made, it is characterized in that: the yarn layer is the composite bed of yarn outer surface parcel polymer resins layers.The yarn layer has soaked fluoropolymer resin class material (Polymer Resin), fluoropolymer resin class material (Polymer Resin) through permeate → absorb → form lamination layer structure of polymer resins layers and the formation of yarn layer from skinning at the yarn outer surface after condensing, this lamination layer structure has more suppleness than original prehensile material, and weight does not have great changes, can not only play and isolate all kinds of liquid effects, and have more durability, and bounce-back, soft durometer is more stable, longer service life, more approaching traditional baseball standard makes the whole physical property of baseball 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, the utility model contains by high density cork nuclear is outer and coats football shirt 9 structures that the different wool blend line of the centre of sphere 6, thickness that the several layers high elastic rubber constituted or the formed lamination 7 of other yarns, yarn layer 8 and leather are made.Yarn layer 8 has soaked fluoropolymer resin class material (Polymer Resin), fluoropolymer resin class material (Polymer Resin) through permeate → absorb → form lamination layer structure of polymer resins layers and the formation of yarn layer from skinning at the yarn outer surface after condensing.This layer lamination layer structure has more suppleness than original prehensile material, and weight do not have great changes, can not only play and isolate all kinds of liquid effects, and have more durability, and bounce-back property, soft durometer are more stable, longer service life, more approaching traditional baseball standard makes the whole physical property of baseball better.

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 baseball of improved characteristics, coat football shirt (9) structure that the different formed lamination of wool blend line (7), yarn layer (8) and the leathers of the centre of sphere (6), thickness that the several layers high elastic rubber constituted made by high density cork nuclear is outer, it is characterized in that: the yarn layer is the composite bed of yarn outer surface parcel polymer resins layers.
