Abstract

The utility model discloses a stick tennis, include: the covering layer is internally provided with a hollow cavity, the inner surface and the outer surface of the covering layer are spherical surfaces, and the hollow cavity is enclosed by the inner surface; the inner core layer is provided with a porous structure and is filled in the hollow cavity. This baton tennis adopts inside and outside layered structure, and wherein, the interior sandwich layer has porous structure, and under the hard circumstances of colliding with the health in overburden, the porous structure of interior sandwich layer can produce great deformation, absorbs the impact effectively, plays fine cushioning effect, and is little to sportsman's injury, and the security performance is high, and the overburden can keep the motion characteristic moreover, makes this baton tennis satisfy the match requirement.

Description

Stick tennis

Technical Field

The utility model relates to a sports goods field especially relates to baton tennis.

Background

Stick tennis, also known as lacrosse or tennis, is called the fastest ball game in the world, has been developed rapidly in North America, is popular all over the world, and can be controlled by athletes or enthusiasts through ball bags at the head of a club head, so that the coordination of hands and feet of players, basic technology and team cooperation are taught, and the severity of physical confrontation is not inferior to that of American football games.

Stick tennis belongs to solid spheroid, current stick tennis is in order to keep the motion characteristic and compromise the specification in the aspect of aerodynamic force and weight, generally use harder solid rubber integrated into one piece, because the ball moving speed is very fast, for the sportsman, if the health is hit by stick tennis, the light person is painful, heavy person is injured, though in the official match sportsman need wear the protective equipment, can prevent that many important positions from receiving accidental injury, still some health position do not receive the protection, some enterprising level fans do not wear the protective equipment at all even, therefore, can't fundamentally stop the injury of stick tennis to the sportsman, the injury is the important reason that hinders the sportsman to participate in this motion.

SUMMERY OF THE UTILITY MODEL

The utility model discloses aim at solving one of the technical problem that exists among the prior art at least. Therefore, the utility model provides a stick tennis, it is under the prerequisite that keeps the motion characteristic, and the security performance is high, and is little to sportsman's injury.

According to the utility model discloses stick tennis, include: the covering layer is internally provided with a hollow cavity, the inner surface and the outer surface of the covering layer are spherical surfaces, and the hollow cavity is enclosed by the inner surface; the inner core layer is provided with a porous structure and is filled in the hollow cavity.

The method has the following beneficial effects: this baton tennis adopts inside and outside layered structure, and wherein, the interior sandwich layer has porous structure, and under the hard circumstances of colliding with the health in overburden, the porous structure of interior sandwich layer can produce great deformation, absorbs the impact effectively, plays fine cushioning effect, and is little to sportsman's injury, and the security performance is high, and the overburden can keep the motion characteristic moreover, makes this baton tennis satisfy the match requirement.

According to some embodiments of the invention, the inner core layer is made of rubber foam.

According to some embodiments of the invention, the cover layer is made of rubber.

According to some embodiments of the invention, the outer surface of the inner core layer abuts the inner surface of the cover layer.

According to some embodiments of the invention, the outer diameter of the inner core layer is 1/3 to 2/3 of the outer diameter of the cover layer.

According to some embodiments of the invention, the sum of the weight of the cover layer and the inner core layer is 144-147 g.

Drawings

The above and/or additional aspects and advantages of the present invention will become apparent and readily appreciated from the following description of the embodiments, taken in conjunction with the accompanying drawings of which:

fig. 1 is a schematic cross-sectional view of an embodiment of the present invention;

fig. 2 is a schematic cross-sectional view of a cover layer according to an embodiment of the present invention.

Reference numerals: the coating comprises a covering layer 1, a hollow cavity 11, an inner core layer 2 and a porous structure 21.

Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary only for the purpose of explaining the present invention, and should not be construed as limiting the present invention.

In the description of the present invention, unless explicit filling, enclosing, making, and abutting words should be understood in a broad sense, those skilled in the art can reasonably determine the specific meaning of the words in the present invention by combining the specific contents of the technical solution.

Referring to fig. 1 and 2, the utility model discloses a stick tennis ball, include: the cladding layer comprises a cladding layer 1 and an inner core layer 2, wherein a hollow cavity 11 is arranged in the cladding layer 1, the inner surface and the outer surface of the cladding layer 1 are both spherical surfaces, and the hollow cavity 11 is enclosed by the inner surface; the inner core layer 2 has a porous structure 21, and the hollow cavity 11 is filled with the inner core layer 2.

This embodiment adopts inside and outside layered structure, and under the hard circumstances of colliding with the health at overburden 1, the porous structure 21 of interior sandwich layer 2 can produce great deformation, absorbs the impact effectively, plays fine cushioning effect, and is little to sportsman's injury, hits the health position after, the sportsman does not have obvious pain sense, and the security performance is high, and overburden 1 can keep this baton ball's motion characteristic and traditional baton ball to keep unanimously.

It will be appreciated that the outer surface of the core layer 2 abuts the inner surface of the cover layer 1 to provide a squeezing action, which effectively transfers the force of the cover layer 1 to the core layer 2 and, likewise, the force of the core layer 2 to the cover layer 1.

In addition, referring to fig. 1, the outer diameter of the core layer 2 is 1/3 to 2/3 of the outer diameter of the cladding layer 1, and when the outer diameter of the core layer 2 is 1/2 of the outer diameter of the cladding layer 1, it is possible to maintain good motion characteristics and very high safety.

In some embodiments of the present invention, the sum of the weight of the cover layer 1 and the weight of the inner core layer 2 is 144-147 g, which meets the weight requirement of the competition.
