Description of the invention: [Technical field to which the invention pertains] The tree is related to the golf club head, and in particular to the joint structure of the golf club head housing and the bottom plate. [Prior Art] It is known that a golf club head consisting of two or three metal components can be joined by welding or brazing, but 3 is a piece of reinforced plastic or carbon fiber. The non-two H made of resin is combined with a metal element, or a low-light light metal element such as a magnesium alloy or a good alloy is required to be bonded to a general metal element type, but the adhesive is used early, and there is a lack of adhesion. SUMMARY OF THE INVENTION [15] The main object of the present invention is to provide an old-fashioned joint structure, i can be supplied to: ^ = = 尔 尔 # head and bottom genus; · shell or pour point of the light genus The preferred combination strength of the body and the metal base plate. In view of the above, according to the present invention, a golf club head housing and a joint structure of the forehead, the neck has a shaft hole, and the body has a 'part' - a person. The shaft rod is fixedly inserted, and the inner end of the neck is provided with a 4σ technician plate, which is disposed at the bottom end of the casing, and corresponds to the neck joint portion:=two parts; the joint member connects the joint portion of the shell and the bottom plate, It is used to connect the shell to the bottom money. Pressing the mouth #本月的# The head of the ball is directly connected to the bottom plate by the neck and the joint member 20 200819173, and the overall structural strength is better. Further, the head of the present invention adopts the engagement design of the convex portion and the groove at the joint portion between the casing and the bottom plate, so that the strength of the joint is better and the assembly is more convenient. [Embodiment] The second embodiment is described with reference to the following figures: As shown in the first to third figures, the golf club head (10) according to the first embodiment of the present invention comprises: a casing (20) having a The neck (21), the neck (21) has a shaft hole (22), 10 is for the Nalfu shaft (not shown) to be inserted and fixed, and the bottom end of the neck is provided with a joint portion (23). The joint portion (23) of this embodiment is provided with a bottom wall (24) at the inner bottom end of the neck portion, and a through hole (25) having a smaller inner diameter than the shaft hole is provided in the center of the bottom wall. A bottom plate (30) is disposed at a bottom end of the casing (20), and a joint portion (31) is disposed at a position corresponding to the neck portion (23) of the neck portion (21). The joint portion (31) of the embodiment protrudes from the bottom plate (30) by an inclined cylinder, and a screw hole (32) is recessed from the column end. A joint member (40), the joint portion (23) (31) of the joint housing (20) and the bottom plate (30) is used to fix the shell (20) and the bottom plate (30) integrally. The joint member (40) of this embodiment is a bolt, the head portion (41) of which is received at the bottom end of the shaft hole (22) 20 of the neck portion (21), and the body portion (42) passes through the neck portion (21). The perforation (25) is screwed to the bottom plate (3 (^) of the screw hole (32), and the housing (20) and the bottom plate (30) are locked and fixed by screwing. A ball striking panel (50), It is disposed in front of the casing (20) and the bottom plate (30) to form a ball striking surface of the golf club head (10). 5 200819173 A convex portion (26) is provided at the joint end of the casing (20) and the bottom plate (30). The groove (33)' is used to strengthen the bonding strength between the two. In this embodiment, the convex portion (26) is provided in the casing (2), and the groove (33) is provided in the bottom plate (30). a 'protrusion (51) is provided at the joint end of the ball striking panel (50), and a recess (27) (34) is provided at a corresponding position of the shell 5 body (2) and the bottom plate (30). It is to strengthen the bonding strength. In this embodiment, a convex portion (28) is formed below the position of the neck (21) with the groove (27), and the ball striking panel (5... forms a groove (52) at the corresponding position. By this, a double-clamping structure is formed between the hitting panel (5〇) and the neck (21), and the hitting panel (5〇) and the casing (2〇) are strengthened in the neck (21). ) The joint strength of the position is effective to prevent cracks which may occur due to the ball striking stress. The present invention combines the head shell (2〇) and the bottom plate (3〇) into an integral 'fitted convex joint by the joint member (4〇) The embedding action of the portion (26) and the groove (33) greatly enhances the bonding strength between the casing (20) and the bottom plate (3〇), so that the present invention can only be used as an adhesive (Example I5 such as a lyophilized resin). The casing (2〇) is firmly combined with the bottom plate (3〇) without cracking. Also, because of the above-mentioned joint structure of the present invention, the casing (2〇) can use engineering plastic or fiber-reinforced resin (for example, carbon fiber). ) Non-metallic materials, or bismuth magnesium alloys or light alloys with lower melting points such as alloys, and bottom 2 slabs (30) can be made of titanium or stainless steel or heavier tungsten or nickel. Metal material. The ball striking panel (50) can use titanium alloy or stainless steel or aging steel to be more elastic metal material. As shown in the fourth figure, it is a schematic structural view of the second embodiment of the present invention. The head (60) of the embodiment is provided with a screw at the joint portion 6200819173 (72) of the inner end of the neck (71) of the casing (70). (73) 'This embodiment is obtained by placing a nut (74) at the inner end of the neck portion (71), and the joint portion (81) of the bottom plate (80) is provided with a groove (82) having a larger inner diameter and a smaller inner diameter perforation (83), the engagement member (90) is screwed from the bottom plate (80) through the groove (82) and the perforation (83) to the screw hole (73) of the neck portion (71) Although the joint structure of the present invention is designed for a plastic or composite material or a metal head having a low melting point and a metal bottom plate, the structure can of course be applied to a conventional metal shell and metal. The combination of the bottom plate. 7 200819173 [Simple description of the drawings] The first figure is a front view of the first embodiment of the present invention. The second figure is a cross-sectional view taken along line 2-2 of the first figure. The third figure is a cross-sectional view taken along line 3-3 of the first figure. 5 is a schematic view showing the structure of a second embodiment of the present invention.
