Abstract

A baseball with improved structure is composed of a high-density cork core, several layers of high-elasticity rubber layers, several laminated layers formed by winding the blended wool or other yarns, and a water-proof layer made of plastics, rubber or other similar materials between said laminated layers and ball cover. It has the advantages of preventing the ball volume layer from being affected with damp, further stabilizing the ball body characteristics and maintaining good performance.

Description

modified baseball

The utility model relates to a solid core ball in the field of ball games, in particular to a baseball with an improved structure that can prevent the ball volume layer from being damp and maintain good performance even in a rainy environment.

As shown in Figure 1, the structure of the baseball used in official games is generally composed of a high-density cork core covered with several layers of high-elastic rubber layers, the ball core 10 is formed by winding blended wool yarns of different thicknesses or other spinning yarns. The laminated layers 11 and jerseys 12 are formed; the laminated layers 11 formed by blended wool yarn or other spinning yarns have better water absorption, when the sphere is used in areas with high humidity or in rainy environments , the laminate 11 is likely to increase the weight of the ball due to the increase in water content and affect the rebound coefficient of the ball, causing the pitcher to lose control of the ball due to the change in the weight of the ball and produce an abnormal rebound when the ball is hit or rolled , so that the use performance of the sphere is unstable, and may cause unsafe and unfair use process.

The purpose of this utility model is to improve the shortcomings of the increase in weight of the ball and the abnormal rebound caused by the increase in the water content of the laminated layer when the above-mentioned conventional baseball is used in an area with high humidity or in a rainy (rainy season) environment. To provide a baseball with an improved structure, even when the baseball is in a rainy environment, the ball volume layer can be prevented from getting wet, so that the baseball can maintain good performance.

The purpose of this utility model is achieved by the following technical solutions.

A baseball with an improved structure, which is generally composed of a high-density cork core covered with several layers of high-elastic rubber layers, multiple laminated layers and jerseys formed by winding blended wool threads of different thicknesses or other spinning threads ; It is characterized in that a layer of water-proof layer made of plastic, rubber or other similar materials is added between the laminate and the jersey. The water-proof layer can effectively block the penetration of water liquid or water vapor.

Concrete structure of the present utility model is provided in detail by following embodiment and accompanying drawing thereof.

Fig. 1 is a sectional view of a conventional baseball.

Fig. 2 is a perspective view of the utility model.

Fig. 3 is a sectional view of the utility model.

In order to further understand the structural features of the present utility model, hereby cooperate with the embodiment shown in Fig. 2 and 3, and describe in detail as follows:

As shown in Figures 2 and 3, the utility model generally consists of a ball center 20 composed of a high-density cork core covered with several layers of high-elastic rubber layers, a number of blended wool threads with different thicknesses or other spinning threads wound to form Laminated layer 30 and jersey 40 constitute; The technical feature of the present utility model is, add one deck water-proof layer 50 made of plastics or rubber or other similar materials between this laminated layer 30 and jersey 40, this water-proof layer The layer 50 can effectively block the penetration of water or water vapor.

The utility model can block the contact between the laminated layer 30 and the water liquid (air) by adding a water-proof layer 50 between the laminated layer 30 and the jersey 40, so that the sphere will not accumulate even when it is in an environment with high humidity or rainy days. Layer 30 can also maintain a normal dry state, so that the weight and rebound coefficient of the ball can be maintained within a stable value, so that the baseball can show a normal rebound effect when pitching or controlling the ball and when it is hit or rolled, so that it can reach Safe and fair good performance.

From the above description and the embodiment shown in the accompanying drawings, it can be known that the utility model can achieve a stable elastic coefficient compared with the conventional baseball at present, so that the use of the baseball is safer and more fair. Therefore, the utility model has the advantages of Significant practicability and progress, and it has never been seen before, meets the requirements of a new patent, so a patent application is filed according to law.

The above is only a preferred embodiment of the utility model, and does not limit the utility model in any form. Any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the utility model, All still belong to within the scope of the technical solution of the utility model.

Claims (1)
