Description

Technical Field

[0001] This utility model relates to the field of billiard cue technology, specifically a diameter circumference comparison measuring device for billiard cues. Background Technology

[0002] A billiard cue is a striking tool, generally made of wood, tapering from front to back, and no shorter than 91cm. A cue that is too long is difficult to control and affects aiming and striking; therefore, it's important to choose a cue suitable for your skill level. The shaft is round, tapering from front to back, straight, and between 1.3m and 1.5m in length, with a tip (thin end) diameter of approximately 9-12mm. The quality of the tip directly affects the shot. A high-quality leather tip is elastic, controlling the impact force and preventing slippage. To prevent slippage, apply anti-slip powder to the tip after three or four shots. Regularly trim and polish the tip to maintain its optimal condition. The cue head is usually made of hard metal or plastic, and the tip is glued to it for protection.

[0003] When using modern billiard cues, the shaft and handle section need to be fixedly connected. The traditional joint structure has insufficient concentricity, which leads to misalignment after installation, affecting the accuracy of the shot. At the same time, when the handle section or shaft is lost and a replacement cue is needed, constant measurement is required, making the replacement of parts quite troublesome. Utility Model Content

[0004] The purpose of this invention is to provide a diameter circumference comparison measuring device for billiard cues, in order to solve the problems mentioned in the background art. When using current billiard cues, the cue body and handle section need to be fixedly connected. The traditional joint structure has insufficient concentricity, which leads to misalignment after installation, affecting the accuracy of the shot. At the same time, when the handle section or cue body is lost and a replacement cue is needed, continuous measurement operations are required, which makes the replacement operation more troublesome.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A diameter circumference comparison measuring device for a billiard cue includes a main docking block, with a blocking outer ring fixedly disposed on the outer side of the main docking block. Both the main docking block and the blocking outer ring are made of copper. A measuring outer ring is fixedly sleeved on the outer side of the main docking block, with the outer side of the measuring outer ring flush with the outer side of the blocking outer ring. A through hole is horizontally formed at one end of the main docking block, located along its central axis. Both ends of the through hole are open. A second main docking block is horizontally connected to one end of the main docking block. The material of the second main docking block is the same as that of the main docking block, and one end of the second main docking block is horizontally connected to one end of the main docking block. The mating assembly features a second blocking outer ring fixedly mounted on the outer side of the second mating block. A second measuring outer ring is horizontally fixedly fitted onto the outer side of the second mating block. The dimensions and material of the second measuring outer ring are consistent with those of the first measuring outer ring. An extension tube is horizontally fixedly connected to one end of the second mating block. One end of the extension tube is fixedly connected to the center of one end of the second mating block and horizontally inserted into the inner side of the through hole. A mating through hole is horizontally formed at one end of the second mating block, located along the inner central axis of the second mating block and the extension tube. An external thread is fixedly mounted on the outer side of the extension tube, and internal threads are evenly distributed on the inner side of the through hole.

[0007] In a preferred embodiment of this utility model, the main docking block is made of copper and is cylindrical in shape, while the outer blocking ring is fixedly arranged in a ring shape on the outer side of the main docking block near the center line.

[0008] In a preferred embodiment of the present invention, the measuring outer ring is arranged in a tubular structure and is fixedly sleeved at one end of the outer side of the docking main block, with one end of the measuring outer ring docked at one end of the blocking outer ring.

[0009] In a preferred embodiment of this utility model, the through hole is horizontally opened at the center of one end of the main docking block one, and the other end of the through hole extends outward through the other end of the main docking block one to form an opening. One end of the main docking block two and one end of the main docking block one are both set to a completely flat state.

[0010] In a preferred embodiment of this utility model: the second blocking outer ring is fixedly disposed on the outer side of the second docking main block near the center position. The material of the second blocking outer ring is consistent with the material of the second docking main block. One end of the second measuring outer ring is disposed at one end of the second blocking outer ring, and the outer side of the second measuring outer ring is flush with the outer side of the second blocking outer ring.

[0011] In a preferred embodiment of this utility model, the material of the extension tube is consistent with that of the docking main block two, and the internal threads are evenly arranged on the inner side of the through hole near one end. The extension tube is fixedly connected to the inner side of the mating internal threads by the fixed external threads.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention connects a main docking block one end to the center of the handle of a billiard cue, and a measuring outer ring one end to the handle. A main docking block two end is fixedly connected to the center of the end of the cue stick, and a measuring outer ring two end to the end of the stick body. An extension tube extends beyond the outside of the stick body. During splicing, the extension tube is inserted into the opening of a through hole. Rotation of the stick body causes the extension tube to rotate, connecting the external fixing thread and the mating internal thread for a secure connection. The outer ring 1 is perfectly aligned with the outer ring 2 at one end, ensuring a perfect fit between the handle joint and the shaft. Since the through hole and extension tube are both located at the absolute center of the connecting blocks 1 and 2, perfect concentricity is achieved after assembly. When needing to add handle joints or shafts later, the thread size of the outer ring 1 or 2 can be used to match the joints. The modular structure makes installation more convenient, and the high concentricity and specified dimensions of the connection structure result in better concentricity after installation, facilitating subsequent joint matching.
