Abstract

The utility model discloses a baseball bat structure, which comprises a batting part made of a wooden material and a holding part made of a PU material connected to the batting part, wherein a hard rod piece in the center of a baseball bat is disposed inside the bating part and the holding part and connects the two parts and the hard rod piece is filled with a foam material; the front end of the batting part forms a baseball head and a counter hole is formed by the batting part from the rear end center to the batting part inside in order for coordination of the hard rod piece; the rear end of the batting part forms an expanded hole and the PU material is filled in the expanded hole when the holding part is formed; and the rear end of the batting part forms a necking on which a fixation sleeve is disposed. According to the baseball bat structure with a good hand feeling, noise is reduced and strength of the whole baseball bat can be increased with low cost.

Description

A kind of bat structure

Technical field

The utility model is about a kind of bat structure, refers to especially a kind of lightweight, batting soft handle, saves the bat structure of material cost.

Background technology

Baseball is that a kind of blackjack ball is main feature, the ball game project that communality, antagonism are very strong; It carries out comparatively extensive in the world, affects greatlyr, is described as the combination of wisdom " sports with "; Particularly prevailing in the U.S., Japan, be called as " national ball game ".Therefore, baseball just starts to promote from children.

Traditional bat processes mainly with timber, and the weight of whole bat is heavier, for striker, if not larger arm strength, can be slack-off because of waist speed of gyration when swinging, the momentum of order batting diminishes, and ball cannot fly farly; In addition, be subject to the limited impact of timber resources, bat timber cost is high; Moreover, for the weak children of strength, use traditional bat training to be difficult to reach and operate effect smoothly.Therefore just there is the bat of aluminium matter, but this bat but cannot compare favourably with wooden bats in feel and the texture of square stance, and the sound of not only batting is large, and the injury of the harder square stance meeting of bat arm is larger, be unfavorable for children or exercise use, this case just produces thus.

Utility model content

The purpose of this utility model is to provide a kind ofly to be had lightweight, batting soft handle, saves the bat structure of material cost.

For achieving the above object, solution of the present utility model is:

, it comprises the driving part of wood materials and the grip part of the PU material that is connected with driving part, driving part with in grip part, be provided with one and be connected the two and be positioned at the hard rod member at bat center, in this hard rod member, be filled with expanded material.

Described driving part front end forms baseball head, and it forms driving part counterbore and coordinate for hard rod member in rear end in mind-set driving part.

The rear end of described driving part forms a necking down, is equipped with a fixed cover on it.

Described fixed cover is coated and is formed by carbon fiber or glass fibre.

The rear end of described driving part forms a reaming, and when moulding grip part, PU material is filled in reaming.

Described grip part is to be formed outside the hard body of rod by PU forming materials.

Expanded material in the described hard body of rod is PU expanded material.

The described hard body of rod is fiberglass pipe or carbon fiber pipe.

Adopt after such scheme, the driving part of being made by wood materials due to bat of the present utility model can be realized bat and bat normally, and soft handle reduces noise simultaneously; The grip part of being made by PU material, can effectively reduce the material cost of bat; And arranging of the hard body of rod is mainly the effect of playing bat support frame, can improve the intensity of whole bat, filling-foam material wherein can have the function of damping and silencing.

In addition, fixed cover arranges the further bonding strength that has improved driving part and grip part.

Accompanying drawing explanation

Fig. 1 is the schematic perspective view of the utility model bat;

Fig. 2 is the structure cutaway view of the utility model bat;

Fig. 3 is the partial enlarged drawing of Fig. 2.

The specific embodiment

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

As shown in Figure 1 to Figure 3, the utility model has disclosed a kind of bat structure, and it comprises driving part 1 and the grip part 2 being connected with driving part 1, driving part 1 with in grip part 2, be provided with one and be connected the two and be positioned at the hard rod member 3 at bat center.

Described driving part 1 is to be made by timber, and its front end forms baseball head, and it forms driving part 1 counterbore 11 and coordinate for hard rod member 3 in rear end in mind-set driving part, separately in the rear end of driving part 1, form a necking down 12.

Described grip part 2 is by PU(polyurethane resin) take shape in outside the hard body of rod 3 and form.

In the described hard body of rod 3, be filled with expanded material 4, this expanded material 4 can be PU expanded material; And the hard body of rod 3 can be fiberglass pipe or carbon fiber pipe.

In addition, be further equipped with a fixed cover 5 in the necking down 12 of driving part 1, fixed cover 5 herein can be coated and be formed by carbon fiber or glass fibre.

When bat is made, first the hard body of rod 3 front portions that are filled with expanded material are embedded in the counterbore 11 of driving part 1, and twine and cover after fixed cover 5 in the necking down 12 of driving part 1 rear end, be placed in the lump mould, grip part 2 is shaped in to the rear portion of the hard body of rod 3, and after simultaneously the necking down of fixed cover 5 and driving part 1 12 is coated, completed being connected of driving part 1 and grip part 2, just completed the making of whole bat.

Certainly, the rear end of above-mentioned driving part 1 also can form a reaming, and when moulding grip part 2, plastic material can be filled in can be realized equally driving part 1 in reaming and be connected with the good of grip part 2.

The bat forming by said structure, the driving part 1 of being made by wood materials can be realized bat and bat normally, and soft handle reduces noise simultaneously; The grip part 2 of being made by PU material, can effectively reduce the material cost of bat; And arranging of the hard body of rod 3 is mainly the effect of playing bat support frame, can improve the intensity of whole bat, filled with foaming material 4 wherein can have the function of damping and silencing; Fixed cover 5 the further bonding strength that has improved driving part 1 and grip part 2 is set.
