Description

Composite bat with multi-cavity structure

Technical field:

The utility model relates to the technical field of sports equipment, in particular to a baseball bat.

Background technique:

The traditional baseball bat has a hollow structure, which has insurmountable shortcomings: when the user uses the bat for a long time, the vibration is large, the noise is large, the section rigidity and strength are poor, the elasticity is poor when hitting the ball, and the hitting speed is slow.

From Figures 1 and 2, the hitting zone of a traditional bat has only a single tube 50, and the tube wall 51 is connected as one. When the bat hits the ball, it will produce a considerable vibration. There is no device for absorbing and dispersing vibration, so the vibration will be directly transmitted to the palm of the human body, causing fatigue and easy injury to the hand.

Invention content:

The purpose of the utility model is to overcome the defects of the prior art and provide a composite bat with a multi-cavity structure, which has good structure, small vibration and comfortable use.

In order to achieve the above object, the utility model adopts the following scheme:

Composite bats with a multi-cavity structure include ball bats. The cavities of the bat have multiple cavities, which exist in part or all of the cavities of the bat.

The multi-body cavity is a two-tube or multi-tube structure, and is square, circular, fan-shaped or elliptical; the multi-body cavity and the bat are made integrally or combined and embedded.

Shock-absorbing materials are filled in the cavities in the multi-body cavity.

The multi-body lumen can be fibrous body, plastic body or rubber body.

Compared with the prior art, the utility model designs the cross-section of the bat lumen into a multi-cavity structure, improves the cross-sectional rigidity and strength of the bat, increases the elasticity of the cross-section of the bat, and makes the user more powerful when hitting the ball, thereby improving the strength of the bat. The backlash force enables the user to hit the ball farther, with less vibration and less noise when using this bat.

Detailed ways:

Below in conjunction with accompanying drawing, the utility model is further described:

As shown in Figures 3, 4, and 5, the composite bat of the multi-cavity structure described in the present invention includes a bat 1, and the cavity structure of the bat 1 has a multi-cavity 2, which can exist in the bat 1. Partial or full location of the lumen.

The multi-body cavity 2 is a two-tube or multi-tube structure, and is square, circular, fan-shaped or elliptical. The multi-body cavity 2 can be made of materials such as fiber, plastic or rubber, and the multi-body cavity 2 is embedded with the bat 1. Of course, integral molding is not excluded.

As shown in Figures 6 and 7, the multi-body cavity 2 can be hollow or solid. As shown in Figure 7, the cavity in the multi-body cavity 2 can be filled with shock-absorbing materials, such as PU, EVA and other shock-absorbing materials. Material.

The method of this creation is: first form the main body 1 of the bat structure, as shown in Figure 5, and then use molding or other methods to produce the tube cavity structure monomer 8 (as shown in Figure 6), and its material can be fiber, plastic or other materials , the middle can also be filled with shock-absorbing materials such as PU and EVA, as shown in Figure 7, one or more structural monomers 8 are assembled into the shape of Figure 8, that is, a multi-body cavity 2, and there may be a gap structure 9 in the middle. The shape of the single body 8 and the gap structure 9 can be circular, square, fan-shaped or other shapes, and the multi-body cavity 2 can be made into the striking area of the bat or any part or the whole of the bat.

The utility model can improve the rigidity and strength of the section of the bat, increase the elasticity of the section of the bat, and make the user more powerful when hitting the ball, thereby improving the kickback force of the bat, so that the user can hit the ball more easily when using the bat. Longer distance, less vibration and less noise.
