Abstract

The utility model relates to an improved structure of a ball inner container, in particular to an improved structure of a seamless ball inner container, wherein an inner container with a ball-shaped bag is arranged as a seamless ball main body structure, a yarn layer is coated on the outer surface of the inner container, the outer surface of the yarn layer is provided with an emulsion layer, and a ball covering layer is connected on the outer surface of the emulsion layer, wherein the yarn layer is preset a base point from the outer surface of the inner container and is braided with a plurality of intersections with interlaced knitted lines in a diffusing way towards the periphery, and gaps are formed among the intersections and the knitted lines, and the emulsion layer is filled in the gap of the yarn layer so as to form a complete ball body. A special knotting and braiding mode is adopted to work through the yarn layer, the expansion of the ball inner container can be effectively controlled when the inner container is aerated and expanses, when the inner container is internally expanded and is squeezed by outside, different intersections get same forcing intensity, and deformation and cracking of the inner container are reduced.

Description

Ball inner bag structure-improved

Technical field

The ball inner-tube structure of the relevant a kind of seamless ball of the utility model is meant that especially one has the ball inner bag structure-improved of special knotting weaving manner.

Background technology

The kind of ball has multiple; simply any is to go out spheroid with the elastomeric material straight forming; gas is poured into to be about to spheroid behind the spheroid and to strut into the rubber-like ball; identification requirement based on vision, sense of touch and ball kind; spherome surface has various dimpled grain usually, similarly is that the basketball surface has that countless particles, football surface have a plurality of hexagon coverings and the baseball surface has one continuously and the bent suture of the arc that engages.

In conventional techniques, general sphere structure is made up of inner bag, inseam layer and out-seam layer; The processing procedure of this kind conventional techniques is: be most pieces with cloth cutting at first, it is all identical given shape, then the inner surface of out-seam layer is coated viscose and is attached the inseam layer, then drying the viscose backlash cuts down and merge its sewing joint, turn-over formed a pocket after stitching finished, and sealed and inflate the adjustment shape behind the inner bag of packing into.

In the above-mentioned habitual sphere structure, at two adjacent layer of cloth intersections, it is yielding to have a stressed back of pullling, and causes suture to expose gradually, in the course of time even further the shortcoming of fracture; And the inseam layer of this kind conventional techniques and out-seam layer typically use canvas and make, and are not easy to attach fully firmly when multi-level attaching is binded, and cause the dislocation of out-seam layer and inseam interlayer crooked when being subjected to shearing action easily.

Habitual another kind of sphere structure is made up of inner bag, interior layer and out-seam layer, and fills material prior to being provided with one in the out-seam layer, again layer in inner surface is coated the viscose attaching; Though the habitual spheroid of this kind replaces above-mentioned inseam layer with interior layer, and to fill material increase ball thickness, the raising structural strength is used and is avoided distortion and fracture, but still have and identical shortcoming at the out-seam layer, even because the thickness of suture reduces, so yielding all the better fracture when the suture that approaches is subjected to shearing.

And habitual another sphere structure is made up of inner bag, inseam layer, out-seam layer and exodermis, and above-mentioned exodermis is bonding on the out-seam laminar surface, and in the staggered mode that coincides suture is not exposed; Though the habitual spheroid of this kind increases ball thickness and structural strength with exodermis, but on still having, inseam layer and out-seam layer take off identical shortcoming, and the inner bag inflation is adopted the random number braiding because of the inseam layer, can't effectively prevent the distortion of ball inner bag, therefore, traditional sphere structure truly has necessity of being improved.

Summary of the invention

Main purpose of the present utility model, aim to provide a kind of ball inner bag structure-improved, see through thread layers and adopt specific knotting weaving manner operation, can when the inner bag inflation, effectively control its scope that swells, inner bag is when inside expansion and external compression in addition, each interface point all is identical on the force intensity being subjected to, and makes that inner bag is difficult for producing distortion and breaking.

For reaching described purpose, the utility model ball inner bag structure-improved is provided with one and has the inner bag of spherical capsule bag as seamless ball agent structure, and coat in above-mentioned inner bag outer surface a thread layers is set, and above-mentioned thread layers outer surface is provided with the emulsion layer that a gluing is used, connect a slick and sly smooth-going covering layer in above-mentioned emulsion layer outer surface in addition, wherein, above-mentioned thread layers weaves a plurality of staggered interface points of knitting line that have by basic point of inner bag outer surface to diffusion all around, and between above-mentioned interface point and knitting line, form the space, and filling up the space of above-mentioned thread layers, above-mentioned emulsion layer forms a complete spheroid.

Above-mentioned interface point is to be cross-linked institute by at least four knitting lines to constitute, and controls the percentage elongation and the expansion amplitude of each interface point by this; And above-mentioned covering layer comprises a packed layer and the adjacent exodermis that rearranges of lamellar body by the identical preset shape of most pieces that directly is fitted and connected outside above-mentioned emulsion layer, in a preferred embodiment, above-mentioned exodermis is a hot plastic polyurethanes material, above-mentioned filling material is an ethylene vinyl acetate copolymer material, and above-mentioned thread layers is to be made of 85% Polyester Yarns and 15% cotton yarn blending.

Advantage of the present utility model is to see through thread layers and adopts specific knotting weaving manner operation, can when the inner bag inflation, effectively control its scope that swells, inner bag is when inside expansion and external compression in addition, each interface point all is identical on the force intensity being subjected to, and makes that inner bag is difficult for producing distortion and breaking.
