The utility model solves the deficiencies of the prior art, has the advantages of reasonable structure, good elasticity, soft texture, good wear resistance and anti-impaction capability, does not harm the body of children in exercise, has good safety performance and can advance and extend the age of ball exercise. The size and the weight of the throwing ball can be regulated according to the filling material in the liner, so as to obtain balls of all dimensions with the same size and the different weight or with the same weight and different size.

Description

Throwing ball

Technical Field

The present invention relates to a ball for use in sports, and more particularly to a throwing ball having an inner bladder and a polymer foam surface layer covering the inner bladder.

Background

There are a variety of sports, in which shot is an indispensable competitive and fitness item. It can exercise and enhance physical and psychological quality of people, and enhance the coordination of organs, especially hands of people. However, most of the common shots on the market are made of metal and are hard balls, and the outer surfaces of the shots are hard and are easily damaged even if the shots are slightly touched by people. And the impact force is strong in the process of movement, so that the body of people, especially children, is easily injured. These balls typically adjust their weight by increasing or decreasing their weight by increasing the material of the ball during manufacture, so that the ball size determines its weight, and the weight cannot be changed at will without changing its volume, and the weight of these balls is typically large and not suitable for younger children.

Disclosure of Invention

The to-be-solved technical problem of the utility model is: in order to effectively overcome the defects, the soft throwing ball is provided with the inner container and the polymer foaming surface layer coated outside the inner container, the softness of the ball body is moderate, and the total weight of the throwing ball can be randomly adjusted by adjusting the weight of the inner container, so that the soft throwing ball is suitable for teenagers and children of different ages.

The technical solution of the utility model is that: a throwing ball is provided with an inner container and a high polymer foaming surface layer coated outside the inner container.

In the throwing ball, the inner container is a solid body, and the high polymer foaming surface layer is an integral covering layer formed by directly foaming the polyurethane material at the periphery of the solid inner container.

In the throwing ball, the polymer foaming surface layer can be provided with a filling hole, and the inner container is a solid body formed by filling the filling hole into the ball body.

In the throwing ball, the curvature radius of the solid inner container is equal to the radial thickness of the foaming surface layer coated on the outer side of the inner container.

In the throwing ball, the curvature radius of the solid inner container is half of the radial thickness of the foaming surface layer coated on the outer side of the inner container.

In the throwing ball, the solid inner container can be approximately round or oval.

The utility model has the advantages that: the utility model provides a throw ball, it makes this ball rational in infrastructure by having polymer foaming top layer at solid inner bag outer cladding, has elasticity good, and the texture is soft, and wear-resisting and strong advantage of anti-impact strength can not cause the injury to children's health in the motion, has good security performance, can be in advance with the age that the extension ball was taken exercise. The size and the weight of the throwing ball can be adjusted according to the materials filled in the inner container, so that balls with the same volume and different weights or different weights, volumes and specifications can be obtained.

Fig. 1 is a schematic cross-sectional view of a first embodiment of the present invention;

fig. 2 is a schematic cross-sectional view of a second embodiment of the present invention.

Detailed Description

The present invention will be further described with reference to the accompanying drawings and specific embodiments.

Example 1

As shown in fig. 1, the present invention has an inner container 1 and a polymer foaming surface layer 2 coated outside the inner container 1. Wherein,

the inner container 1 is a solid body which is approximately round or an elliptical solid body. The polymer foamed surface layer 2 is an integral covering layer formed by directly foaming on the periphery of the solid liner 1.

When in processing, the solid liner 1 is lifted by a rope-shaped object 3, the rope-shaped object can be any material capable of bearing weight, then a macromolecule foaming process is adopted, an outer surface layer 2 is formed outside the solid liner 1, and the outer surface layer 2 can be a polyurethane foaming layer. In the foaming forming process, the rope-shaped object 3 and the surface layer can be dissolved into a whole; a small hole can also be left on the surface of the ball body at the rope-shaped object.

The curvature radius of the solid inner container 1 is equal to the radial thickness of the foaming surface layer 2 coated outside the inner container 1.

The utility model discloses an extexine of throwing ball adopts polymer foaming top layer 2, and it is soft material, and elasticity is good, and the texture is soft, and wear-resisting and impact resistance are strong, can not cause the injury to the people when taking exercise, greatly increased its suitability. During manufacturing, the size and the weight of the solid liner 1 can be adjusted according to the filled material, or the thickness of the foaming surface layer 2 can be adjusted, so that spheres with the same volume and different weights or the same weight and different volumes and various specifications can be obtained.

Example 2

As shown in fig. 2, the foamed polymer skin layer 2 may be provided with a hole 3, and the inner container 1 may be a substantially circular solid body formed by injecting the inner container into a sphere through the hole 3.

When in processing, firstly a polymer foaming surface layer 2 is formed, a filling hole 4 is preset on the surface layer 2, the polymer foaming surface layer can be filled with materials through the filling hole 4 so as to adjust the weight of the thrown ball, a nearly circular solid body is formed in the surface layer of the ball body, and finally the filling hole 4 can be blocked, so that the thrown balls with various weight specifications can be obtained. Therefore, the ball exercise device is suitable for teenagers and children of different ages, and can advance and prolong the ball exercise age.

Other structural features and advantageous effects of the throwing ball are the same as those of embodiment 1, and are not described herein again.

Example 3

The radius of curvature of the solid bladder 1 may be about half the radial thickness of the foamed skin 2 coated on the outside of the bladder 1.

Other structural features and advantageous effects of the throwing ball are the same as those of embodiment 1 or embodiment 2, and are not described herein again.

It should be understood, however, that the description herein of specific embodiments is not intended to limit the scope of the invention, but on the contrary, the intention is to cover all modifications, equivalents, and alternatives falling within the spirit and scope of the invention as defined by the appended claims.
