Description

Golf axostylus axostyle with reinforced structure

The utility model is relevant with golf club, particularly about a kind of golf axostylus axostyle with reinforced structure.

The axostylus axostyle (shaft) of general golf club mostly is the tubular body that fiber reinforced composite material (as carbon fiber) is made now, Figure 1 and Figure 2 is two kinds of structures of commonly using for this type of shaft configurations intensity of reinforcement, wherein the former is on axostylus axostyle 70 shafts and establishes some metal fines 71 that extend vertically, the latter then is that radiation-like is embedded into some sheet metals 81 that extend vertically in axostylus axostyle 80 tube walls, this two structure is all very bothersome on making, can't volume production.Moreover, as schematically shown in Figure 3, aforementioned tubular shaft is reeled by a fiber sheet 90 to form, and the superimposed of coiling end can make the axostylus axostyle respective side form structural strength stronger " ridge is leant on (spine) " than thickness portion 91, the preceding phenomenon of taking off two reinforced structures and can't solve this intensity inequality.

Main purpose of the present utility model is promptly providing a kind of golf axostylus axostyle with reinforced structure, and it can strengthen axostylus axostyle intensity equably, and manufactures easily, has concurrently simultaneously and beautifies the ornamental of axostylus axostyle.

Take off purpose for before reaching, the golf axostylus axostyle with reinforced structure provided by the utility model, the body of aforementioned axostylus axostyle is to make with fibrous composite, is the canalis spinalis shape, butt end is carefully held in order to link a bar head in order to a sheathed handle; It is characterized in that: have more at least one on the side face of this axostylus axostyle body in the shape of a spiral around the metal wire that covers and be fixed on the shaft.

Wherein the side face of this axostylus axostyle body has more an outer fibrage that covers that is coated on this metal wire.

Wherein should outer cover fibrage is transparent material.

Wherein the shaft integral body of this axostylus axostyle body all is arranged with the aforementioned metal line.

Wherein the only local figure of this axostylus axostyle body is arranged with the aforementioned metal line.

Wherein the packing of this metal wire coiling has density to change.

Wherein the hand of spiral of this metal wire winding is single rotation direction.

Wherein the hand of spiral of this metal wire winding has opposite two rotation directions, and the line segment intersection of different rotation directions is overlapping, makes this metal wire be the side face that the graticule mesh shape is located at this axostylus axostyle body.

Now lift some preferred embodiments and cooperate graphic being described as follows, wherein:

Fig. 1 is a kind of golf axostylus axostyle of commonly using with reinforced structure;

Fig. 2 is the sectional drawing of the golf axostylus axostyle with reinforced structure commonly used of another kind;

Fig. 8 is the outside drawing of the utility model the 4th preferred embodiment.

Golf axostylus axostyle provided by the utility model mainly by winding metal wire on the axostylus axostyle body to reach the structural strengthening effect, in following each embodiment.The material of aforementioned axostylus axostyle body is carbon fiber (only also can be character other fibre strengthening type composite roughly the same), and its method for making is with to commonly use the carbon fiber axostylus axostyle identical, and appearance is not given unnecessary details; Axostylus axostyle thickness two ends are respectively in order to establish handle and the bar head that connects golf club.

Please consult Fig. 4 earlier, be arranged with a metal wire 21 on the side face of the axostylus axostyle body 11 of the utility model first embodiment, this metal wire 21 is that relative axostylus axostyle body 11 prolongs cloth to the other end with the single hand of spiral by the winding of shaft one end, production method be the carbon fiber lamella when pre-epoxy resin dipping roll into tubulose but be not heated as yet hard solid before, metal wire is wound to the axostylus axostyle body side face that still is wet sticking state with coil winding machine, after treating the hard moulding admittedly of composite heating, metal wire 21 can be incorporated on the axostylus axostyle body 11.See also Fig. 5, the utility model more can be in aforementioned process after being covered with metal wire 21, again on axostylus axostyle body 11 lining one pre-epoxy resin dipping the outer fibrage 31 that covers, outermost layer and temporarily wrapping fixes that (heating removes after finishing with glued membrane, not shown in the figures), when be all fibrous composite outer to cover fibrage 31 and 11 heating of axostylus axostyle body hard solid and after being combined into one, this metal wire 21 can fastened Bao Shu on axostylus axostyle body 11; Again, should outer cover fibrage 31 in this example is to adopt transparent glass fibre, so promptly still can see this metal wire 21, it is harmless that it is ornamental and have a sense.

Around covering this metal wire, axostylus axostyle can obtain uniform structural strengthening by spiral, and stress can immediately axially conduct toward circumference all directions and shaft by metal wire when stressed, effectively prevents to rupture because of bearing excessive external force.In addition, this metal wire has the decorative pattern effect of beautifying the axostylus axostyle surface simultaneously concurrently, and the structural strengthening effect is given visualization, the desire to buy that can stimulate consumer.

Metal wire of the present utility model also can only be set around on the local shaft of axostylus axostyle, sees also Fig. 6, and wherein metal wire 22 only is wrapped on the bending point (kitpoint) of axostylus axostyle body 12 stressed maximums, that is does the emphasis reinforcement at the possible rhegma place of axostylus axostyle.Certainly, can also be set around diverse location on the shaft respectively by several metal wires, form some coiling reinforcement sections.

Please consult Fig. 7 again, this embodiment produces the different reinforcing effect of intensity by the coiling packing that changes metal wire 23: the narrow close coiling of shaft keypoint part mat is obtaining higher structural strengthening power, otherwise the loose coiling of other figure gets final product.

In addition, before being not limited to, takes off the spiral canoe of the utility model metal wire the single rotation direction of all examples, see also Fig. 8, metal wire 24 wherein promptly has opposite two rotation directions (it is contrary around finishing only to turn back with single metal wire), and the line segment intersection that rotation direction is opposite is overlapping, make metal wire 24 form the lattice net blanket and be overlying on axostylus axostyle body 14 surfaces, so that so that higher structural strengthening ability to be provided.
