Abstract

The utility model discloses a super elasticity bowling pin relates to the sports goods field, and this super elasticity bowling pin's base top is equipped with taking over a business of a disc, and the side of taking over a business is outside bellied arc, and the center of taking over a business is equipped with the heavy core of a disc. Base that rubber made rebounds after being knocked down down by the bowling with to take over a business elasticity better more easily, takes over a business to set up a heavy core and can make this pin top -heavy, is touched down over more easily, can effectively reduce the degree of difficulty of bowling, makes the bowling campaign promote more easily.

Description

Super bowling pin

Technical field

The utility model relates to sports goods field, in particular to a kind of super bowling pin.

Background technology

Bowling is a kind of indoor sport that spin hits post on duck-board, as much as possible ten pins is knocked down score with a bowling. Existing bowling pin adopts paint wood to manufacture mostly; and surface scribbles one layer of plastic cement protection paint; elastic force is limited; pin cannot significantly rebound after going down; it is difficult to knock other bowling of periphery over; add game difficulty, it is very difficult to arouse the enthusiasm that people are engaged in bowling campaign, thus it is difficult to universal bowling campaign.

Practical novel content

Technical problem to be solved in the utility model is to provide a kind of super bowling pin, the up big and down small truncated cone-shaped base of rubber manufacture and taking over a business of disc are set, and taking over a business the interior heavy core that metal is set, to increase elasticity and the roll capability of pin, reduce the difficulty of bowling campaign.

For achieving the above object, the utility model provides following technical scheme: a kind of super bowling pin, it is characterized in that: described super bowling pin comprises the base of a up big and down small Rotary-table shape, base top is provided with taking over a business of a disc, the side taken over a business is the circular arc of outwardly convex, the center taken over a business is provided with the heavy core of a disc, and heavy core is by metal.

Preferably, described base and taking over a business by elastomeric material manufacture, and base and taking over a business for one-piece construction.

Preferably, big 2 times of the diameter of the diameter proportion core taken over a business described in.

Preferably, the height of described base is 4 times that take over a business thickness.

The useful effect of above technical scheme is adopted to be: the base top of this super bowling pin is provided with taking over a business of a disc, and the side taken over a business is the circular arc of outwardly convex, and the center taken over a business is provided with the heavy core of a disc. The base of rubber manufacture, with taking over a business elasticity better, more easily rebounds after being knocked down by bowling, takes over a business to arrange heavy core and this pin can be made top-heavy, more easily knocked over, can effectively reduce the difficulty of bowling, bowling campaign is more easily promoted.

Accompanying drawing explanation

Below in conjunction with accompanying drawing, embodiment of the present utility model is described in further detail.

Fig. 1 is the structural representation of a kind of super bowling pin of the utility model;

Fig. 2 is the structure sectional view of a kind of super bowling pin of the utility model.

Wherein, 1-base, 2-take over a business, the heavy core of 3-.

Embodiment

The preferred implementation of a kind of super bowling pin of the utility model is described in detail below in conjunction with accompanying drawing.

Fig. 1 and Fig. 2 shows the embodiment of the utility model a kind of super bowling pin: this super bowling pin comprises the base 1 of a up big and down small Rotary-table shape, what base 1 top was provided with a disc takes over a business 2, the side taking over a business 2 is the circular arc of outwardly convex, making 2 to be more prone to roll, knock other pins over, the center taking over a business 2 is provided with the heavy core 3 of a disc, heavy core 3 is by metal, heavy core 3 density is big, pin can be caused top-heavy, it is easy to knocked over.

Composition graphs 1 and Fig. 2, base 1 and take over a business 2 by elastomeric material manufacture, and base 1 and take over a business 2 for one-piece construction, base 1 and take over a business 2 good springiness, be more prone to bullet after being knocked down by bowling and fall other pins. Take over a business big 2 times of the diameter of the diameter proportion core 3 of 2, ensure that the elasticity of 2 is not influenced. The height of base 1 is 4 times that take over a business 2 thickness.

The base 1 of rubber manufacture and to take over a business 2 elasticity better, more easily rebounds after being knocked down by bowling, takes over a business 2 and arranges heavy core 3 this pin can be made top-heavy, is more easily knocked over, can effectively reduce the difficulty of bowling, bowling campaign is more easily promoted.

Above is only preferred implementation of the present utility model; it is noted that for the person of ordinary skill of the art, under the prerequisite not departing from the utility model creation design; can also making some distortion and improvement, these all belong to protection domain of the present utility model.
