Description

Technical Field

[0001] This utility model relates to the field of billiard equipment technology, specifically to a billiard cue head structure, a billiard cue, and a billiard ball. Background Technology

[0002] The end of a billiard cue is fitted with a tip, which is usually glued to the front of the cue. The tip is generally made of high-quality leather. Due to its suitable elasticity and friction, the tip can control the impact force when hitting the ball and the spin of the ball in motion.

[0003] Currently, cue tips are typically designed with a convex spherical structure, bearing the force of each shot. Furthermore, the contact between the tip and the cue ball surface is always point contact, making them very prone to damage and requiring frequent replacement. To address this issue, existing technologies incorporate an internally threaded hole at the cue tip and an externally threaded rod at the rear of the tip, creating a detachable structure for easy tip replacement. However, since the cue tip is generally made of wood, frequent disassembly and replacement can cause wear on the wooden threads, easily damaging the internal threads in the internally threaded hole and significantly impacting the cue's lifespan. Utility Model Content

[0004] In view of the deficiencies in the existing technology, the purpose of this utility model is to provide a billiard cue head structure, a billiard cue, and a billiard ball.

[0005] According to the present invention, a billiard cue head structure includes a first connector, an intermediate component, and a second connector. The rear end of the intermediate component is disposed at the end of the rod head via the first connector. The front end of the intermediate component has a second mounting hole. The rear end of the second connector is detachably disposed on the second mounting hole. The front end of the second connector has a mounting surface for mounting the tip. Both the intermediate component and the second connector are made of metal. The circumferential edge of the rear end of the intermediate component forms a limiting sleeve, which extends to the rod head and covers the rod head circumferentially.

[0006] Preferably, the intermediate component and the limiting sleeve are integrally formed.

[0007] Preferably, the end of the limiting sleeve away from the intermediate member extends into a limiting edge in a radially inward direction, and the end of the rod head is circumferentially provided with a groove; The limiting edge extends into the groove.

[0008] Preferably, the intermediate component and the limiting sleeve are welded together.

[0009] Preferably, the intermediate component and the second connector are respectively provided with a first tool slot and a second tool slot in their circumferential directions.

[0010] Preferably, both the first connector and the second connector are screws.

[0011] Preferably, the second assembly hole is a stepped hole, and the rear end of the second connector is a stepped column structure that matches the stepped hole, thereby making the second connector and the intermediate part concentrically arranged.

[0012] Preferably, the limiting sleeve, intermediate component, and second connecting component are all made of copper or aluminum.

[0013] According to the present invention, a billiard cue adopts the aforementioned cue head structure.

[0014] A billiard ball according to the present invention includes the aforementioned billiard cue.

[0015] Compared with the prior art, the present invention has the following beneficial effects: This invention, by adding an intermediate component, allows for easy replacement of the cue tip via a second metal connector and the intermediate component, minimizing damage during disassembly and reassembly. This solves the problem in existing technologies where frequent disassembly and replacement leads to wear on the wooden threads and damage to the internal threads in the internal threaded hole, significantly extending the lifespan of the billiard cue. Furthermore, the first connector fixes the intermediate component to the end of the cue tip, and the limiting sleeve further strengthens the connection between the intermediate component and the cue tip. Once the first connector is secured to the cue tip, disassembly is no longer required, reducing the risk of wear from repeated disassembly and reassembly. Simultaneously, the connection between the limiting sleeve and the intermediate component further enhances the overall stability and practicality. Attached Figure Description

[0017] The diagram shows: Club head 1; Limiting sleeve 2; Limit edge 21; First connector 3; Middleware 4; First tool slot 41; Second connector 5; Second tool slot 51; Pipe tip 6. Detailed Implementation

[0018] The present invention will now be described in detail with reference to specific embodiments. These embodiments will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way. It should be noted that those skilled in the art can make several changes and improvements without departing from the concept of the present invention. These all fall within the protection scope of the present invention.

[0019] Example 1: To address the problem of frequent disassembly of the threaded shaft at the rear end of the cue tip, which leads to easy wear and tear on the wooden threads and shortens the lifespan of the cue, this utility model provides a cue tip structure, including a first connector 3, an intermediate component 4, and a second connector 5, as follows: Figure 1 , Figure 2 As shown, the rear end of the intermediate part 4 is disposed at the end of the rod head 1 via the first connector 3. The front end of the intermediate part 4 has a second mounting hole. The rear end of the second connector 5 is detachably disposed on the second mounting hole. The front end of the second connector 5 has a mounting surface for mounting the tip 6. The mounting surface is preferably a plane, and the tip 6 is preferably bonded to the mounting surface.

[0020] Both the intermediate part 4 and the second connecting part 5 are made of metal, such as copper, stainless steel, or aluminum. The second connecting part 5 uses screws. When the cue tip 6 is worn and needs to be replaced, simply remove the second connecting part 5 from the intermediate part 4 and replace it with a new second connecting part 5 and cue tip 6 to complete the replacement of cue tip 6. Since both the intermediate part 4 and the second connecting part 5 are made of metal, they are not easily damaged during repeated disassembly and disassembly, which greatly increases the service life of the billiard cue.

[0021] like Figure 1 As shown, a limiting sleeve 2 is formed at the circumferential edge of the rear end of the intermediate member 4. The limiting sleeve 2 extends onto the club head 1 and covers it circumferentially. Specifically, the limiting sleeve 2 extends a limiting edge 21 in a radially inward direction from the end away from the intermediate member 4.

[0022] Furthermore, such as Figure 5As shown, the end of the club head 1 is circumferentially provided with a groove, and the limiting edge 21 extends into the groove, so that the limiting sleeve 2 can be stably held at the end of the club head 1. The limiting sleeve 2 is also made of metal, such as copper, stainless steel, aluminum, etc. The intermediate part 4 is welded to the limiting sleeve 2, and the intermediate part 4 and the limiting sleeve 2 form a whole to form an overall wrap and protection for the end of the club head 1, which can effectively avoid damage caused by external wear.

[0023] This utility model first fixes the intermediate part 4 to the end of the rod head 1 through the first connecting part 3, and then makes the connection between the intermediate part 4 and the rod head 1 more secure through the limiting sleeve 2. The first connecting part 3 is preferably a metal screw. After the first connecting part 3 is fastened to the rod head 1, it does not need to be disassembled. Moreover, the connection between the limiting sleeve 2 and the intermediate part 4 makes the connection between the intermediate part 4 and the rod head 1 more secure, which increases the stability of the overall structure.

[0024] For ease of assembly, the intermediate component 4 and the second connecting component 5 are respectively provided with a first tool slot 41 and a second tool slot 51 in their circumferential directions. Both the first tool slot 41 and the second tool slot 51 are designed for easy disassembly using tools; for example, both the first tool slot 41 and the second tool slot 51 are flat-mouthed slots. Figure 2 As shown, the second connector 5 can be easily removed from the intermediate part 4 by placing a wrench on the flat groove. In practical applications, two wrenches can be used, one on the first tool slot 41 and the other on the second tool slot 51, which can easily remove the second connector 5 from the intermediate part 4 and avoid the torque being transmitted to the first connector 3, making the billiard cue head structure more practical.

[0025] like Figure 1 As shown, the second assembly hole is a stepped hole with three spaces of different outer diameters at the front, middle and rear ends. The three spaces are concentrically connected in sequence, and the outer diameters gradually increase. The front and middle parts of the second assembly hole form the first stepped hole, which facilitates the fixing of the rear end of the first connector 3. In order to facilitate assembly, the cross-section of the middle space of the second assembly hole can be a regular hexagon, which, together with the regular hexagonal structure of the screw tail end, forms an anti-rotation structure. Therefore, it is only necessary to drive the intermediate part 4 to rotate relative to the rod head 1 to assemble the first connector 3 to the end of the rod head 1, thereby achieving a stable connection between the rod head 1 and the intermediate part 4.

[0026] Furthermore, the middle and rear ends of the second assembly hole form a second stepped hole structure, and the rear end of the second connector 5 is a stepped column structure that matches the second stepped hole, thereby enabling the second connector 5 and the intermediate part 4 to be arranged concentrically, so as to achieve accurate positioning of the second connector 5 on the intermediate part 4 during assembly.

[0027] This utility model also provides a billiard cue with a cue head structure that extends the service life of the cue.

[0028] This utility model also provides a billiard ball, including a billiard cue.

[0029] Example 2: The difference between this embodiment and embodiment 1 is that the intermediate component 4 and the limiting sleeve 2 are integrally formed structures, such as... Figure 3 , Figure 4 As shown, to increase the stability of the connection between the rod head 1 and the intermediate part 4, the limiting sleeve 2 and the end of the rod head 1 can be bonded together.

[0030] Taking Example 1 as an example, the working principle of this utility model is as follows: like Figure 1 , Figure 2 As shown, when the tip 6 is worn and needs to be replaced, take two wrenches, place one wrench on the first tool slot 41 and the other on the second tool slot 51. Twist the wrench on the second tool slot 51 to drive the second connector 5 to rotate the tip 6 relative to the intermediate part 4. Since the wrench on the first tool slot 41 bears the torque, the first connector 3 and the rod head 1 are not under force or are almost not under force, so the second connector 5 and the tip 6 can be removed from the intermediate part 4. Then, assemble the second connector 5 with the new tip 6 onto the intermediate part 4 to complete the replacement of the tip 6.
