The utility model relates to a golf ball head with adjustable balance weight position and weight, particularly a golf ball head which can adjust the balance weight position and the weight according to the needs of users. The utility model is mainly provided with a hollow golf ball head, the rear part points of the lower side in the golf ball head are formed into one or more than one cylindrical main bodies, one end of each main body is provided with an opening, the other end of each main body is provided with a closed end, a screw thread part is arranged in the opening point of each main body, the opening point can be filled with an elastic body with predetermined weight and metal powder with predetermined weight, and the utility model can be fixedly locked, pressed tightly, and sealed by that inner hexagonal screws which are provided with exhaust holes are screwed with the screw thread part; therefore, golf ball head moulds with different balance weight positions manufactured by manufacturers can be saved, the cost of balance weight blocks can also be saved, and users can also make the golf ball head which is in accordance with users' own balance weight position and weight to reach the advantage of club batting and ball waving stability.

Description

The golf club of adjustable balance position and weight

Technical field

The utility model relates to the golf club of a kind of adjustable balance position and weight, especially refers to a kind of device that is used on the golf club.

Background technology

General user in order to reach the stability that swings, can select the suitable club of oneself controlling when hitting golf; Each club manufacturer can produce the club of different counterweights for user's selection according to different swing weights, the existing practice all is the balancing weight that Different Weight is set in the downside of bulb or the suitable position of rear side, and the user can select the bulb of different counterweights according to different demands; When the user selected to be fit to the golf clubs of own counterweight, square stance can reach the stability that swings.

The golf club of existing tool counter weight device is one-body molded mostly, in the bulb body, form the embeded slot of a depression, the balancing weight of weight is decided in the embedded unification of its embeded slot, as No. the 368887th, TaiWan, China patent announcement, or utilize locked assembly balancing weight to be locked in the groove of default bulb body recess, as U.S. Pat .6773360 number.The counterweight of above-mentioned structure, all must use hyperbaric tungsten piece to finish and the combining of bulb, because the tungsten piece is to utilize powder metallurgy to make, manufacturer is if make the tungsten piece of different specific weight at various swing weights, process on last or the cost no matter be, all be sizable burden, the feasible price that has the golf clubs of counterweight on the market remains high always.

Summary of the invention

In view of this design people is actively to set about being engaged in research and development, in the hope of improving above-mentioned shortcoming with golf club of counter weight construction, through constantly test and effort, develops the utility model finally.

Main purpose of the present utility model is to provide the golf club of a kind of adjustable balance position and weight, and it is inexpensive and can be according to user's demand, and custom-made by size meets the balance position of oneself and the bulb of weight, to reach the purpose of the batting stability that swings.

In order to achieve the above object, the utility model takes following technological means to be reached, it includes the golf club of a hollow form, the one or more cylindrical body of place, bulb inner lower rear shaping, this body one end is provided with an opening, the other end is a blind end, inboard, body openings place is provided with the threaded portion, can be provided with and fill the elastomer and the metal dust of preset weight by opening part, the hexagon socket head cap screw by the tool steam vent cooperates solid to be screwed together in the place, threaded portion to give with locking and compress sealing.

The concrete effect that the utility model can obtain includes: club head manufacturer can exempt the bulb of making various different balance positions and different balancing weight weight, to save the cost of making mould and balancing weight, and the user also can ask manufacturer's custom-made by size to meet own required bulb, to reach the advantage of the batting stability that swings.

Main figure number explanation

10 bodies, 11 openings, 12 blind ends

13 threaded portions, 14 elastomer 14A elastomers

15 metal dusts, 16 pads, 17 hexagon socket head cap screws

18 steam vents, 20 bulbs

The specific embodiment

Please referring to shown in Fig. 1-2, the golf club of adjustable balance position of the present utility model and weight, include the golf club 20 of a hollow form, one or more cylindrical bodies 10 of place, bulb 20 inner lower rears shaping, body 10 1 ends of this hollow are provided with an opening 11, end is blind end 12 in addition, body 10 outsides also are provided with threaded portion 13 near inboard, opening 11 place, the elastomer 14 and metal dust 15 of preset weight are set and fill in regular turn by opening 11 places, metal dust 15 wherein is based on hyperbaric tungsten powder, elastomer 14 is the less rubber material of proportion, reaches the purpose of adjustment balance position and weight by the elastomer 14 and the filling of metal dust 15;

One pad 16, be arranged between a metal dust 15 and the hexagon socket head cap screw 17, one hexagon socket head cap screw 17, its inside is provided with the steam vent 18 of axial perforation hexagon socket head cap screw 17, by this hexagon socket head cap screw 17 cooperate solids be locked in 13 places, threaded portion and with together ejection pressing and intrinsic metal dust 15 is compressed with elastomer 14 of pad 16, unnecessary air will see through beyond the steam vent 18 discharge bodies during locking.

The utility model is when assembling, at first getting the elastomer 14 of suitable size inserts in the body 10, insert in the body 10 and with metal dust 15 tungsten powders of required weight again adjacent to elastomer 14 rears, metal dust 15 is provided with a pad 16 with respect to 17 of hexagon socket head cap screws, cooperate solid to screw togather 13 places, threaded portion that are sealed in body 10 with hexagon socket head cap screw 17 again, and by this pad 16 of hexagon socket head cap screw 17 ejections, make pad 16 when compressing metal dust 15, can be with the air of body 10 inside via the gap between pad 16 and the body 10, steam vent 18 by hexagon socket head cap screw 17 inside is expelled to the outside again, because the ratio of metal dust 15 tungsten powders is great, and the center of gravity of golf club is suitably reduced.

Please referring to shown in Figure 3, major part is same as the structure shown in Fig. 1, its difference be in: because the volume of elastomer 14A is greater than the volume of the elastomer among Fig. 1 14, the weight of the metal dust 15 that charges into body 10 inside is reduced, thereby, the center of gravity of the golf club of the center of gravity that can make golf club in Fig. 1 is slightly shifted to rear side, can make golf club can have the effect of different balance positions and weight by replacing of the present utility model.

Please referring to shown in Figure 4, major part is same as the structure among Fig. 3, its difference be in, can be in Fig. 4 with elastomer 14A among Fig. 3 and metal dust 15 location swaps, can make the center of gravity of golf club slightly shift to the place ahead, make golf club have different balance positions and weight effects.

As shown in Figure 5, in the utility model, be same as another embodiment shown in Fig. 1, by overlooking sight, the structures such as hexagon socket head cap screw 17 that two groups of bodies 10, elastomer 14, metal dust 15, pad 16, tool steam vent 18 are wherein arranged, also can be arranged at the symmetric position place at golf club inner lower rear, can reach the balance position of adjustment golf club and the effect of weight equally.

In sum, because the metal dust 15 (tungsten powder) in the utility model does not need to make the tungsten piece as known person with powder metallurgy, and the utility model had not only reduced manufacturing cost but also can be according to user's needs, the tailor-made bulb that meets own balance position and weight obviously the utlity model has remarkable and concrete effect.
