Cloth-attached and wire-wound combined type ball inner container and sports ball thereof

Technical Field

The utility model relates to a ball product technical field specifically is a paste cloth wire winding combined type spheroid inner bag.

Background

Sports balls are very common sports facilities in daily life, like basketball, football and volleyball, are inflatable sports balls, and the inflatable sports balls need to be inflated with enough air in the use process, so that the pressure in the inner container of the balls reaches a certain value.

The inner container of the inflatable sport ball cannot provide enough binding force to maintain the good roundness of the sport ball, and the inflatable sport ball is often damaged due to the contact with sharp objects in the daily use or playing process, so that the whole inflatable sport ball is damaged and cannot be used after the inner container inside the sports ball is damaged; in addition, because the binding force of the outer covering fabric layer and the rubber layer of the inner containers of some balls is insufficient, the sports ball is easy to deform and bulge when in use; the structural design of the excellent composite middle-layer fabric can not only improve the roundness and bounce index of the sports ball, but also greatly prolong the service life of the product and even reduce the production and manufacturing cost.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a cloth pasting wire winding combined type spheroid inner bag through the improvement to the structure, not only can improve spheroidal intensity, can also guarantee spheroidal elasticity simultaneously, improves the use comfort of sport ball, further reduces the manufacturing cost of spheroid inner bag simultaneously.

In order to achieve the above purpose, the utility model adopts the following scheme: the rubberized fabric and winding combined type sphere inner container comprises a rubber inner container, a winding layer and a rubberized fabric layer, wherein a first winding layer is wound on the outer side of the rubber inner container, and the rubberized fabric layer is laid on the outer side of the first winding layer; the first winding layer is provided with paste or latex, and the cloth pasting layer is bonded with the first winding layer through the paste or latex.

In a further limited technical scheme of the utility model, the cloth-attached and wire-wound composite ball liner is characterized in that the wire winding layer is formed by winding polyester cotton yarn, pure cotton yarn, polyester yarn or nylon yarn; the cloth layer adopts 20, 32 or 40 yarns.

The cloth-attached and wire-wound combined type sphere inner container comprises a cloth-attached body attached to the surface of a first wire-wound layer of the rubber inner container, two inner concave parts are oppositely arranged at the edges of the cloth-attached body, two outer convex parts are oppositely arranged at two sides of the two inner concave parts, the outer convex parts can be embedded into the inner concave parts, and the edges of the outer convex parts and the edges of the inner concave parts of the other cloth-attached body are mutually overlapped to form a reinforced edge; the interior concave part includes two edges the interior concave edge that pastes cloth body limit portion to the inboard setting, form the inner groovy between two interior concave edges, outer convex part includes two edges paste the outer chimb that cloth body limit portion set up to the outside, two outer chimbs form with the arch that the inner groovy matches.

Aforementioned compound spheroid inner bag of cloth winding that pastes, the gross thickness on first wire winding layer and cloth pasting layer is 1.5 ~ 2.5mm, guarantees the elasticity of spheroid inner bag, does not increase the gross thickness of composite bed.

Further, the utility model also provides a sport ball, including the crust and like aforementioned patch wire winding combined type spheroid inner bag, the crust subsides are established at patch wire winding combined type spheroid inner bag surface, sport ball includes but not limited to basketball, volleyball, rugby, football, handball.

The application has the advantages that: the utility model discloses a paste cloth wire winding combined type spheroid inner bag has that the circularity is good, the percentage elongation is low and long service life's characteristics, makes it possess the performance of good ball for the contest. The rubberizing cloth layer in this application scheme is through setting up interior concave part and outer convex part, and laminating is efficient and extravagant cloth, and the overlap portion compares traditional shop's subsides mode significantly reduced, and bladder surface smoothness is high for the spheroid is high at the in-process equilibrium stability, is difficult for taking place to deflect.
