Description

Technical Field

[0001] The invention belongs to an important component of a golf club, and in particular relates to a golf club head. Background Art

[0002] The panel of the head of an existing golf club is directly welded to the bottom, so the entire head is a whole. When hitting a golf ball, the ball is in direct hard contact with the head, and the ball loses a lot of energy, which affects the flight distance of the ball. In order to increase the flight distance of the ball, a golf club head disclosed in application number 202010040965.9 is provided with a crown side groove 20A and a bottom side groove 20B, that is, grooves are opened at corresponding positions of the overall head to improve the flexibility of the face, thereby facilitating the increase of the flight distance of the ball.

[0026] The present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] Reference Figures 1 to 9 The golf club head includes a striking panel 1, a plastic layer 2 and a bottom plate 3. The striking panel 1 and the bottom plate 3 are snap-fitted at the front end. The plastic layer 2 is arranged between the striking panel 1 and the bottom plate 3. The front end of the plastic layer 2 is provided with an opening, which is matched with the inner side wall of the striking panel 1. An air cavity 4 is formed between the plastic layer 2 and the striking panel 1. The bottom plate 3 is provided with an inlet and outlet valve 6 connected to the air cavity. By snap-fitting the front end surfaces of the striking panel 1 and the bottom plate 3, the assembly and matching of the two can be facilitated, and the bottom plate 3 does not deform when the striking panel 1 deforms when striking a ball. By providing the air cavity 4, gas can be injected into the air cavity 4 through the inlet and outlet valve 6, and the air pressure in the air cavity 4 elastically supports the striking panel, so that the striking panel 1 can be uniformly deformed when striking a ball, which greatly improves the flexibility of the striking panel 1, thereby facilitating the increase of the flight distance of the ball.

[0028] like Figures 4 to 6 As shown, the inner wall of the bottom plate 3 is provided with a slot 31, and the inner side of the striking panel 1 is provided with a hook 11, which cooperates with the slot 31, and the hook 11 is distributed on the inner side of the edge of each side of the striking panel 1. The inner side of the striking panel 1 is provided with a vertical edge 15 that is vertically downward, and the vertical edge 15 is perpendicular to the surface of the striking panel 1 used for striking the ball. The vertical edge 15 is arranged along the inner side of the three side edges of the striking panel 1, and there is no vertical edge below the edge of the narrowest side of the striking panel 1, and the vertical edge 15 is U-shaped. The hook 11 is opened on the vertical edge 15, and a gap 16 is formed between the two sides of the hook 11 and the vertical edge 15, so that the hook 11 is independent on the vertical edge 15, so that each hook 11 is conveniently inserted into each corresponding slot 31; multiple hooks 11 are arranged below each side of the striking panel 1, and a hook 11 is arranged separately below the side without the vertical edge 15, so as to facilitate the clamping with the slot 31 at the corresponding position.

[0029] The hook 11 has a hook portion folded outward (away from the center of the striking panel 1), and the inner wall of the slot 31 is provided with a clamping edge. When the hook 11 is engaged with the slot 31, the hook 11 is engaged with the slot 31 so that the hook 11 and the slot 31 are engaged. The striking panel 1 is an integrated structure, and the molding process is convenient.

[0030] like Figure 3 As shown, the front end surface of the plastic layer 2 is provided with a sealing ring 5, and the sealing ring 5 is in close contact with the inner end surface of the striking panel 1. Thus, the sealed space formed by various structures and the air inlet and outlet valves facilitate the adjustment of the air pressure in the space, so that when the ball strikes, the striking panel can be elastically supported and the rebound coefficient can be adjusted.

[0031] like Figure 3 , Figure 6 to Figure 8 As shown, a protrusion 22 is provided on the outer side of the first edge 21 of the plastic layer 2, the first edge 21 of the plastic layer 2 is located at the top of the plastic layer 2, the protrusion 22 cooperates with the card slot 31, and is clamped between the striking panel 1 and the bottom plate 3. The protrusion 22 and the plastic layer 2 are an integral injection molding structure.

[0032] like Fig. 9 As shown, the thickness of the bottom 32 of the bottom plate 3 is greater than the thickness of the top 33 thereof, and a step portion 34 is provided on the inner side of the bottom plate 3, and the inlet and outlet valves 6 are located on the step portion 34. Thus, the center of gravity of the entire ball head is kept at a lower position, which is convenient for use and operation.

[0033] The golf club head also includes a counterweight 7. The step portion 34 is located at the lower part of the base plate 3. The width of the first side 35 of the base plate 3 is greater than the width of the second side 36 of the base plate 3. A club connector 37 is provided on the outer side of the second side 36 of the base plate 3. The first side 35 of the base plate 3 is arranged opposite to the second side 36 of the base plate 3. The step portion 34 is provided with a mounting hole. The mounting hole is opened from one side of the vertical center line of the step portion 34 to the other side. One side of the vertical center line of the step portion 34 is close to the first side of the base plate 3, and the other side of the vertical center line of the step portion 34 is close to the second side 36 of the base plate 3. The length of the mounting hole on one side of the vertical center line of the step portion 34 is greater than the length on the other side of the vertical center line of the step portion 34. The counterweight 7 is embedded in the mounting hole of the step portion 34.

[0034] Since a club connector 37 is provided on the outside of the second side 36 of the bottom plate 3, the center of gravity of the entire golf club head will be biased toward the side where the club connector 37 is located. Therefore, in order to overcome the deviation of the center of gravity from the vertical center line of the golf club head, a counterweight block 7 is provided. Through the reasonable layout of the installation position of the counterweight block 7, the center of gravity of the entire golf club head is located on the vertical center line of the golf club head, and the overall center of gravity is low, which greatly improves the stability when playing. By designing the depth and height of the center of gravity to increase the rebound coefficient, more energy transfer and a more stable high fairway are achieved, thereby improving the speed and controllability of the ball, thereby achieving a longer flight distance and a more accurate fairway.

[0035] like Figure 3 , Figure 7 and Figure 8As shown, the bottom of the plastic layer 2 matches with the inner wall of the bottom plate 3, and the plastic layer 2 is provided with a horizontal plane 23, which is located above the upper end surface 341 of the step portion 34. After the inlet and outlet valves 6 pass through the step portion 34 and the horizontal plane 23, they can be connected with the air cavity 4. Through the matching of the plastic layer 2 and the step portion 34, and the provision of the horizontal plane 23, the inner wall of the plastic layer 2 is also stepped. In the actual production process, in order to ensure the support strength of the gas in the air cavity on the striking panel 1, and to ensure the use strength of the plastic layer 2, the hardness of the material above the horizontal plane 23 is greater than the hardness of the matching part with the step portion 34.

[0036] like Figure 3 to Figure 5 As shown, the striking panel 1 includes a plane 12 and an arcuate edge 13. The arcuate edge 13 is arranged around the plane 12 and folded toward the inside of the plane 12. A groove 14 is arranged inside the junction of the plane 12 and the arcuate edge 13. The sealing ring 5 matches the groove 14. The wall thickness of the groove 14 is smaller than the wall thickness of the plane 12 and the wall thickness of the arcuate edge 13. The vertical edge 15 is located inside the arcuate edge 13. When the striking panel 1 matches the bottom plate 3, the end face of the arcuate edge 13 abuts against the front end face of the bottom plate 3, so that the two are pressed tightly.

[0037] The wall thickness at the groove 14 is smaller than the wall thickness of the plane 12 and smaller than the wall thickness of the arc edge 13, so that when the plane 12 is hit by the ball, under the action of the force, the plane 12 is bent and deformed toward the air cavity 4 side, and through the reasonable setting of the wall thickness, the plane 12 starts to deform toward the air cavity 4 side from the thin wall, so that the entire plane 12 can be deformed evenly, which is convenient for controlling the direction of the ball and for achieving long-distance hitting of the ball. By making the wall thickness at the groove 14 thinner than that at other positions, when the striking panel 1 is deformed, the plane 12 is deformed without pulling the bottom plate 3 to deform, which is conducive to increasing the deformation amount of the striking panel 1, that is, greatly improving the flexibility of the plane 12 and increasing the flying distance of the ball.

[0038] When the golf club head of the present invention is used, gas is injected into the air cavity 4 through the inlet and outlet valves 6. The gas is preferably nitrogen, which can ensure sufficient support force. The nitrogen can protect the corresponding internal parts and components, which is beneficial to improving the overall service life. When the air pressure in the air cavity 4 reaches the corresponding use requirements, the inlet and outlet valves 6 are sealed and the golf club head can be used. When hitting a ball, the plane 12 hits the ball. Since the plane 12 is supported by the gas, the plane 12 can produce a large deformation, so that the ball can be hit from a long distance.

[0039] like Figure 7 to Figure 11As shown, a connector 24 is provided on the lower side of the horizontal surface 23 of the plastic layer 2, a through hole 343 is provided on the step portion 34, the connector 24 is inserted into the through hole 343, a connecting hole 241 is provided on the connector 24, and the inlet and outlet valve 6 can extend into the air cavity 4 after passing through the through hole 343 and the connecting hole 241, and a tapered portion 242 is provided in the connecting hole 241. In order to facilitate the cooperation between the connector 24 and the through hole 343, a stopper is provided in the through hole 343, and the end face of the connector 24 abuts against the stopper.

[0040] By providing a tapered portion 242 in the communicating hole 241 , it is possible to more closely fit with the outer wall of the inlet and outlet valve 6 to prevent air leakage.

[0041] A plug screw 8 is provided at the outer end of the inlet and outlet valve 6, and the plug screw 8 can be tightened on one end of the inlet and outlet valve 6 to achieve the sealing of the inlet and outlet valve 6; when gas needs to be injected into the air cavity 4, the plug screw 8 is unscrewed, and gas is injected through the inlet and outlet valve 6. After the gas injection is completed, the plug screw 8 is tightened to seal the air cavity.

[0042] The above is only a preferred embodiment of the present invention. It should be pointed out that a person skilled in the art can make several modifications and improvements without departing from the inventive concept of the present invention, which all belong to the protection scope of the present invention.
