Description

Technical Field

[0001] This utility model relates to the field of billiard cue technology, and in particular to a billiard cue adapter and a billiard cue front limb structure. Background Technology

[0002] Billiard cues come in two structural forms: one-piece cues and two-piece cues. Two-piece cues mainly consist of a front section and a handle. The front section is threaded to the handle via screws, or the front section is connected to the handle via a connector. Existing patents, such as Chinese patent application number 200320118073.8, disclose a cue connection structure including at least two sections. A connecting post protrudes from the front end of the rear section, while a connecting hole is recessed on the rear end of the front section. A connector made of resin material is placed between the two sections. The connector consists of a base and a sleeve. The connecting post of the rear section passes through the base of the connector and extends into its sleeve, where it is fixed. The sleeve is inserted into the connecting hole on the rear end of the front section and is fixedly connected to it. The connecting post and sleeve are threaded together, and the sleeve and connecting hole are bonded together with adhesive. The connector sleeve disclosed in this patent document is glued and fixed inside the connection hole with adhesive. Once assembled, it cannot be disassembled, so it is impossible to match two-section clubs of different specifications (such as the forelimb and the handle) by replacing the connector. Therefore, the drawback is very obvious, and a solution is urgently needed. Utility Model Content

[0003] In order to solve the above-mentioned technical problems, the purpose of this utility model is to provide a billiard cue adapter and a billiard cue front leg structure.

[0004] To achieve the above objectives, the present invention adopts the following technical solution:

[0005] A billiard cue adapter includes a cylindrical body and a limiting ring integrally connected to the peripheral wall of one end of the body. The body is axially connected with an internal threaded hole and a screw hole. The screw hole is recessed from the bottom wall of the internal threaded hole. The peripheral wall of the body is provided with an external thread.

[0006] Furthermore, a conical surface is provided at the other end of the main body, and the conical surface is located on the side of the external thread away from the limiting ring.

[0007] Furthermore, the peripheral wall of the main body is provided with a smooth contact surface, which is located between the external thread and the limiting ring.

[0008] Furthermore, the screw hole can be an internal hexagonal hole, a Torx hole, a slotted hole, or a cross hole.

[0009] This utility model also provides a billiard cue forelimb structure, including a forelimb cue and the aforementioned billiard cue adapter. The small-diameter end of the forelimb cue is provided with a tip, and the middle of the large-diameter end of the forelimb cue is recessed with a mounting hole. The inner wall of the mounting hole is provided with an internal thread. The main body is detachably installed in the mounting hole. The external thread and the internal thread are threadedly connected, and the limiting ring abuts against the large-diameter end face of the forelimb cue.

[0010] Furthermore, the forelimb rod is provided with a counterweight hole, which is recessed from the bottom wall of the mounting hole, and a counterweight block is detachably installed in the counterweight hole.

[0011] Furthermore, the counterweight hole is a threaded hole, and the counterweight block is a counterweight screw that is threadedly connected to the threaded hole.

[0012] The beneficial effects of this utility model are as follows: In practical applications, the main body of the billiard cue adapter is first aligned with the internally threaded mounting hole on the large-diameter end face of the forelimb cue. Then, a screwdriver is inserted into the screw hole to screw the billiard cue adapter, thereby installing the billiard cue adapter on the large-diameter end of the forelimb cue through the external thread. The limiting ring abuts against the large-diameter end face of the forelimb cue to ensure the positional accuracy and stability of the billiard cue adapter installed on the forelimb cue. The internal threaded hole of the billiard cue adapter can be connected to the stud thread of the billiard cue handle, so that the forelimb cue is connected to the billiard cue handle via the billiard cue adapter, thereby assembling a billiard cue. This cue adapter facilitates the assembly and disassembly of the cue stick and the cue handle. The assembly of the cue stick and the cue handle is secure. Furthermore, depending on the diameter of the stud on the cue handle of different specifications, cue adapters with different inner diameter threaded holes can be replaced, allowing the same cue stick to be assembled and used with cue handles of different specifications. This improves the compatibility and versatility of the cue stick, increases its utilization rate, and reduces operating costs. Attached Figure Description

[0019] To facilitate understanding by those skilled in the art, the present invention will be further described below with reference to embodiments and accompanying drawings. The content mentioned in the embodiments is not intended to limit the present invention.

[0020] like Figures 1 to 4 As shown, the present invention provides a billiard cue adapter, which includes a cylindrical body 1 and a limiting ring 2 integrally connected to one end of the cylindrical body. The body 1 is axially connected with an internal threaded hole 3 and a screw hole 4. The screw hole 4 is recessed from the bottom wall of the internal threaded hole 3. The peripheral wall of the body 1 is provided with an external thread 5.

[0021] This utility model also provides a billiard cue forelimb structure, including a forelimb cue 8 and the aforementioned billiard cue adapter. The small-diameter end of the forelimb cue 8 is provided with a tip 9, and the middle of the large-diameter end of the forelimb cue 8 is recessed with a mounting hole 10. The inner wall of the mounting hole 10 is provided with an internal thread 11. The main body 1 is detachably installed in the mounting hole 10. The external thread 5 is threadedly connected to the internal thread 11, and the limiting ring 2 abuts against the large-diameter end face of the forelimb cue 8.

[0022] In practical applications, first align the main body 1 of this billiard cue adapter with the mounting hole 10 with internal thread 11 on the large-diameter end face of the forelimb 8. Then, insert a screwdriver into the screw hole 4 to screw the billiard cue adapter, thereby installing the billiard cue adapter on the large-diameter end of the forelimb 8 through the external thread 5. The limiting ring 2 abuts against the large-diameter end face of the forelimb 8 to ensure the positional accuracy and stability of the billiard cue adapter installed on the forelimb 8.
