Description

Technical Field

[0001] This utility model relates to the field of billiard cues, and in particular to a composite billiard head cue. Background Technology

[0002] A billiard cue is a tool used in billiards. To accommodate different users, existing billiard cues are divided into a detachable end cue and a head cue. The end cue has a tip for striking the ball, and the end cue is usually connected to the head cue by a threaded connection. When using a billiard cue, the end cue is supported by one hand, while the other hand holds the head cue and applies force.

[0003] The main body of existing billiard cues is generally made of natural wood, such as maple or ash. However, due to the unique characteristics of natural wood, it is difficult to maintain consistency in the finished cue products. Some cues may have good force transmission performance, making it easier for users to hit the ball, while others may have poor force transmission performance, making it difficult for users to hit the ball.

[0004] In view of the above problems, it is necessary to study a composite head cue for billiards, which has the advantage of good consistency in force transmission performance. Utility Model Content

[0005] The purpose of this invention is to provide a billiards composite head cue that has the advantage of good consistency in force transmission performance.

[0006] To achieve the above objectives, the solution of this utility model is: A composite billiard cue stick includes a connecting section and a grip section detachably connected to the connecting section; the connecting section includes a connecting section inner core, a connecting section middle tube, and a connecting section outer sleeve arranged sequentially from the inside to the outside, the connecting section inner core includes at least three connected connecting section sub-cores, the connecting section cores are made of wood and the grain direction of the connecting section cores is arranged along the axial direction of the connecting section, and the connecting section middle tube is made of carbon fiber tube.

[0007] The grip section is made of wood.

[0008] The grip section is made of maple wood.

[0009] The gripping section includes a gripping section inner core, a gripping section middle tube, and a gripping section outer sleeve, which are sequentially arranged from the inside to the outside. The gripping section inner core includes at least three connected gripping section sub-cores. The gripping section sub-cores are arranged along the axial direction of the gripping section and are made of wood. The gripping section middle tube is made of carbon fiber. The gripping section inner core and the gripping section middle tube correspond to the connecting section inner core and the connecting section middle tube, respectively.

[0010] The material of the grip core is maple wood.

[0011] The outer surface of the grip section is covered with a grip leather sleeve.

[0012] The outer surface of the grip section is also covered with a decorative sleeve, with the grip sleeve positioned close to the connecting section and the decorative sleeve positioned away from the connecting section.

[0013] The inner core of the connecting section is fitted with a connecting bolt at the end away from the gripping section, and a connecting nut at the end of the inner core of the connecting section near the gripping section. The end of the gripping section near the connecting section is fitted with a connecting bolt that is screwed into the connecting nut.

[0014] The end of the grip section away from the connecting section is fitted with a soft pad.

[0015] The core of the connecting segment is made of maple wood.

[0016] With the above-mentioned solution, when the user strikes the ball, the composite head cue of this invention mainly transmits the user's force to the tail cue through the connecting section tube. The connecting section tube is made of carbon fiber, which, being an artificial material, allows for good parameter consistency during production, thus ensuring that the composite head cue of this invention has good consistency in force transmission performance. In addition, the carbon fiber tube has good tensile strength and stiffness, enabling the connecting section tube to effectively transmit force to the tail cue, giving the composite head cue of this invention good force transmission performance. Furthermore, the inner core of the connecting section includes at least three interconnected connecting section cores. The connecting section cores are made of wood, and their grain direction is arranged along the axial direction of the connecting section. The small size of the connecting section cores allows for the selection of connecting section cores with nearly identical performance to assemble the inner core of the connecting section, resulting in good consistency in the force transmission performance and hardness of the inner core of the connecting section, further enhancing the consistency of the force transmission performance of the composite head cue of this invention.

[0030] To further explain the technical solution of this utility model, the following detailed description is provided through specific embodiments.

[0031] Example 1: Cooperate Figures 1 to 9As shown in Embodiment 1 of this utility model, the billiard composite head cue of this utility model includes a connecting section 1 and a gripping section 2 detachably connected to the connecting section 1. The connecting section 1 is used to connect the end of the billiard cue, and the gripping section 2 is used for the user to grip. The connecting section 1 includes a connecting section inner core 11, a connecting section middle tube 12, and a connecting section outer sleeve 13, which are sequentially arranged from the inside to the outside. The connecting section inner core 11 includes at least three connected connecting section sub-cores 111. The connecting section sub-cores 111 are made of wood and are arranged along the axial direction of the connecting section 1 with the grain direction. The connecting section middle tube 12 is made of carbon fiber. When a user strikes the ball, the composite head of this invention primarily transmits the user's force to the tail stick through the connecting section tube 12. The connecting section tube 12 is made of carbon fiber, a man-made material that allows for excellent parameter consistency during production, thus ensuring the composite head of this invention exhibits consistent force transmission performance. Furthermore, the carbon fiber tube possesses excellent tensile strength and stiffness, enabling the connecting section tube 12 to effectively transmit force to the tail stick, resulting in a superior composite head of this invention. The cue has excellent force transmission performance. Furthermore, the inner core 11 of the connecting section includes at least three interconnected connecting sub-cores 111. The connecting sub-cores 111 are made of wood, and their grain direction is aligned with the axial direction of the connecting section 1. The small size of the connecting sub-cores 111 facilitates the selection of connecting sub-cores 111 with nearly identical performance to assemble the inner core 11, resulting in good consistency in the force transmission performance and hardness of the inner core 11. This further enhances the consistency of the force transmission performance of the billiard composite head cue of this invention. In addition, the grain direction of the connecting sub-cores 111 is aligned with the axial direction of the connecting section 1, thus ensuring high strength for each connecting sub-core and resulting in high strength for the assembled inner core 11.

[0032] In Embodiment 1 of this utility model, the grip section 2 may include, from the inside out, a grip section inner core 21, a grip section middle tube 22, and a grip section outer sleeve 23. The grip section inner core 21 includes at least three connected grip section sub-cores 211, which are arranged along the axial direction of the grip section 2 and are made of wood. The grip section middle tube 22 is made of carbon fiber. The grip section inner core 21 and the grip section middle tube 22 correspond to the connecting section inner core 11 and the connecting section middle tube 12, respectively. When the user strikes the ball, the billiard composite head of this utility model mainly transmits the user's force to the connecting section 1 through the grip section middle tube 22. Since the grip section middle tube 22 is made of carbon fiber, it can effectively transmit the force to the connecting section 1. In addition, the small size of the grip segment core 211 makes it easy to select grip segment cores 211 with nearly identical performance to assemble the grip segment inner core 21, thereby making the force transmission performance and hardness of the grip segment inner core 21 more consistent.

[0033] In one embodiment of this utility model, the outer surface of the grip section 2 may be fitted with a grip leather sleeve 3 for the user to hold. The grip leather sleeve 3 improves the user's grip feel and friction, making it easier for the user to apply force. In addition, the outer surface of the grip section 2 may also be fitted with a decorative sleeve 4 to improve the overall aesthetics; the decorative sleeve 4 is positioned away from the connecting section 1, while the grip leather sleeve 3 is positioned close to the connecting section 1 for the user to hold.

[0034] In Embodiment 1 of this utility model, the connecting segment core 111 and the gripping segment core 211 can both be made of maple wood. Maple wood has the characteristics of high hardness and resistance to deformation, thus making the connecting segment core 11 and the gripping segment core 21 less prone to deformation, and consequently, making the connecting segment 1 and the gripping segment 2 less prone to deformation. The connecting segment outer sleeve 13 can be made of wood to improve the overall texture of the connecting segment outer sleeve 13; similarly, the gripping segment outer sleeve 23 can also be made of wood.

[0035] In the first embodiment of this utility model, the end of the inner core 11 of the connecting section away from the gripping section 2 is fitted with a connecting bolt 5 for connecting the tail rod, the end of the inner core 11 of the connecting section near the gripping section 2 is fitted with a connecting nut 6, and the end of the gripping section 2 near the connecting section 1 is fitted with a connecting bolt 7 that is screwed to the connecting nut 6 (the connecting bolt 7 is connected to the inner core 21 of the gripping section), so that the gripping section 2 and the connecting section 1 can be detachably connected by a threaded connection.

[0036] In the first embodiment of this utility model, the end of the grip section 2 away from the connecting section 1 may be fitted with a soft pad 8 (such as a rubber pad or leather pad). The soft pad 8 can protect the end of the grip section 2 away from the connecting section 1 and prevent the end of the grip section 2 away from the connecting section 1 from directly contacting the ground.

[0037] Example 2: Cooperate Figures 10 to 12 As shown, the difference between Embodiment 2 and Embodiment 1 lies in the grip section 2. Specifically, in Embodiment 2, the grip section 2 is made of wood (i.e., the grip section 2 is made of wood as a single piece). The grip section 2 can be made of maple, which has high hardness and is not easily deformed, thus making the grip section 2 less prone to deformation.

[0038] The above embodiments and figures are not intended to limit the product form and style of this utility model. Any appropriate changes or modifications made by those skilled in the art should be considered as not departing from the patent scope of this utility model.
