Abstract

The utility model relates to a ball kicking rod which comprises a shaft. The shaft comprises a wood main rod which is provided with a shaft hole and the shaft hole extends scheduled length along an axial center; an inner rod is made of material with higher rigidity than that of wood and is closely arranged in the shaft hole of the main rod; an external coating layer 3 is made of fiber composite material and is covered on and combined with the external surface of the main rod. Therefore, the main rod can play the advantages of wood material, however, the inner rod and the external coating layer can prevent the wood main rod from bending distortion due to humidity and ball controlling stability of the rod can be improved.

Description

The billiard stick of improvement

Technical field

The utility model is relevant with billiard stick, particularly about a kind of billiard stick with improvement axostylus axostyle (Shaft).

Background technology

Press, wood materials is owing to have specific elasticity and toughness, be fit to very much be used for making billiard stick, but it still has some shortcomings and still can't overcome so far, for example wooden club makes moist and flexural deformation easily, moreover then be that the timber that is used for making shaft is taken from natural timber, and same natural timber can form different fibre structures because of becoming long priority and environment difference, therefore after it makes club, the elasticity of each part shaft of this club and rigidity can produce difference with the difference of work fibre structure, and this kind situation can cause considerable influence for the ball-handling of club.

The utility model content

The billiard stick that is to provide a kind of improvement of main purpose of the present utility model, it can be possessed the advantage of wooden shaft but can not be subjected to the influence of environment and flexural deformation, and in other words, it can make wooden club keep its glacing flatness for a long time.

Another purpose of the present utility model is to provide a kind of billiard stick of improvement, and it can improve the stability of ball-handling under the situation that keeps wooden shaft advantage.

For achieving the above object, the billiard stick of a kind of improvement provided by the utility model includes an axostylus axostyle (shaft), and this axostylus axostyle includes:

One wooden mobile jib, it has an axis hole along the axle center definite length extended;

Bar in one is made for high material so that rigidity is more wooden, closely is placed in the axis hole of this mobile jib; And

One outer covering layer, material are fibrous composite; Coating is incorporated into the outer peripheral face of this mobile jib.

Wherein the axis hole of this mobile jib connects mobile jib two ends.

Should interior bar be a hollow lever wherein.

Wherein between 11-11.4mm, the external diameter of butt end is between 19-19.4mm in the external diameter of thin end for this mobile jib; The external diameter of bar is about 6mm in being somebody's turn to do; The thickness of this outer covering layer is between 0.8-1mm.

Description of drawings

The preferred embodiment that develops simultaneously of following conjunction with figs. is further described the utility model, wherein:

Fig. 1 is the front view of the utility model one preferred embodiment;

Fig. 2 is the utility model one preferred embodiment cutaway view on the 2-2 direction in Fig. 1; And

Fig. 3 is the utility model one preferred embodiment cutaway view on the 3-3 direction in Fig. 2.

The specific embodiment

As shown in Figure 1, the billiard stick (10) that the utility model one preferred embodiment is provided, shaft is to be engaged by an axostylus axostyle (shaft) (12) and a pressure pin (butt) (14) to form (annotate: juncture can adopt and be spirally connected or gluing pole mode, because of belonging to known technology, holds and does not describe in detail).The thin front end affixed one first angle (forFule) (16) and a leather point (tip) (18) of this axostylus axostyle (12), the thick rear end of this pressure pin (14) is connected with a pad (bumper) (20).

As Fig. 2, shown in Figure 3, this axostylus axostyle (12) is pushing and drawing shape (taper), and the external diameter of thin end is about 13mm, and the external diameter of butt end is about 20mm.This axostylus axostyle (12) is made of a bar (24) and an outer covering layer (26) in the mobile jib (22),, wherein:

This mobile jib (22) is made by natural wood materials (for example hard woods such as maple, mahogany, walnut), be about 73.66 centimeters (29 inches) in its total length of present embodiment, be pushing and drawing shape, the external diameter of thin end is between 11-11.4mm, and the external diameter of butt end is between 18-18.4mm.The center of mobile jib (22) has an axis hole (28) that runs through two ends along the axle center, and the aperture of this axis hole (28) maintains 6mm approximately.Mandatory declaration be, more than each size and ratio only be a preferred embodiment of the present utility model, its visual border needs and changes.

Bar (24) in being somebody's turn to do, more wooden with rigidity is that the metal of high material-for example or fibrous composite are (as carbon fiber, fiber reinforcement plastic (FRP) etc.)-made, its length and external diameter are corresponding to the axis hole (28) of this mobile jib (22), it is hollow lever (being body) in present embodiment, external diameter is about 6mm, and internal diameter is about 4mm.Should closely be placed in the axis hole (28) of this mobile jib (22) by interior bar (24).

This outer covering layer (26), coating is incorporated into this mobile jib (22) outside, its material is a fibrous composite (carbon fiber for example, glass fibre, fiber reinforcement plastic (FRP) etc.), thickness between 0.8-1mm (in other words, the entire outer diameter of this axostylus axostyle (12), thin end is about 13mm, butt end is about 20mm).(annotate: this outer covering layer (26) is to utilize in the common technology, fiber layer of cloth with pre-epoxy resin dipping holds (rolling) mobile jib (22) side face, or with fibre bundle spiral winding (winding) mobile jib (22) side face, being heated solidify to form again, and this non-the utility model target is so will not describe in detail.)

By as can be known aforementioned, billiard stick provided by the utility model (10), axostylus axostyle wherein (12) can be brought into play the certain elasticity and the toughness of wooden club by this wooden mobile jib (22) at square stance.In addition, axostylus axostyle (12) central authorities insert this interior bar (24) that buries and this outer covering layer (26) that the outside coated, can prevent that this wooden mobile jib (22) is subjected to extraneous climate influence and flexural deformation, make axostylus axostyle (12) can keep its glacing flatness for a long time, simultaneously, the visual actual needs of interior bar (24) and outer covering layer (26) is selected suitable material, for example metal or fibrous composite, and the institutional framework of these materials can make it be consistent according to present manufacturing technology, therefore, to be subjected to fibre structure own to influence the disappearance of its ball-handling property minimum when being reduced to for wooden club commonly used.

Claims
