Abstract
Description
Technical Field
[0001] This utility model relates to the field of billiard cue technology, and in particular to an adjustable weighted structure for billiard cues. Background Technology
[0002] In billiards, different players have different hitting habits and power control methods, resulting in varying requirements for cue weight. Adjustable weight structures for billiard cues have emerged to address this need, allowing players to flexibly adjust the cue weight according to their individual requirements. This leads to better feel and power generation during shots, improving accuracy and consistency, and ultimately, enhancing performance. This design is significant for both professional players and billiards enthusiasts, helping them better perform at their best in the sport.
[0003] Currently, some billiard cues on the market adjust their weight primarily by adding a fixed weight block inside the shaft. This involves pre-installing a space at a specific location on the shaft to hold the pre-made weight block, thus increasing the overall weight of the cue. The technical principle is to use simple physical assembly to fix the weight block inside the shaft, allowing the cue to reach a preset weight. This method is relatively simple and direct, and to some extent, it can meet the needs of some users who require a different weight for their billiard cue.
[0004] Existing billiard cues have fixed weight blocks, making them difficult to replace quickly and easily once installed. When players experience changes in game conditions or their own performance, it's hard to adjust the cue weight promptly, hindering the ability to find optimal feel and power points during shots. Furthermore, the fixed weight blocks are difficult to fit snugly inside the shaft, making them prone to displacement during use. This not only affects the cue's balance but also leads to uneven power distribution during shots, negatively impacting the player's performance. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: an adjustable weighting structure for a billiard cue, including an extension rod. A limiting component is provided at one end of the extension rod to limit the weight block. A front rod is provided at the other end of the extension rod, and a cue head is provided at one end of the front rod. A sliding rod is slidably connected inside the extension rod, and a pushing component is provided at one end of the sliding rod to push the weight block to its limit position.

[0014] Optionally, the threaded cap is fitted with the weight block, and the threaded cap is used to limit the movement of the weight block.
[0015] The adjustable weighted billiard cue structure provided in this embodiment of the utility model has at least one of the following technical effects:
[0016] 1. In this utility model, the weight can be easily replaced as needed by removing and installing the threaded cap, thereby adjusting the weight of the billiard cue. The movement of the weight is not only achieved by installing the threaded cap, but also by the cooperation of the push plate and the slide rod, which makes the weight fit tightly with the cue body and the spring achieves the limit. This not only provides the flexibility of weight adjustment, but also ensures the safe fixation of the weight, thereby preventing the weight from shifting during use.

[0029] Reference Figure 1 , Figure 2 and Figure 3 This utility model provides an embodiment of an adjustable weighted billiard cue structure, including an extension rod 1. One end of the extension rod 1 is provided with a limiting component, which is used to limit the weight block 6 to ensure that the weight block 6 can be stably positioned in the required position and will not be displaced during use. The other end of the extension rod 1 is provided with a front rod 2, and one end of the front rod 2 is provided with a cue head 3. The cue head 3 serves as the striking part of the billiard cue and directly contacts the billiard ball, playing the role of transmitting force. A sliding rod 9 is slidably connected inside the extension rod 1, and one end of the sliding rod 9 is provided with a pushing component, which is used to push the weight block 6 to be limited.
[0030] The propulsion assembly includes a push plate 7, the outer wall of which is fixedly connected to one end of a slide rod 9, and the other end of the slide rod 9 is fixedly connected to a limiting plate 10. The push plate 7 can push the weight block 6 toward the extension rod 1 through the sliding action of the slide rod 9. A spring 8 is sleeved on the outer wall of the slide rod 9 near the push plate 7. The limiting assembly includes a threaded cap 4, the inner wall of which is threadedly connected to one end of the extension rod 1. One end of the extension rod 1 has an external thread 5. The spring 8 plays a role in buffering and transmitting thrust when the weight block 6 moves. When the weight block 6 reaches the position, the spring 8 uses the thrust generated by compression to ensure that the weight block 6 is tightly attached to and stable on the outer wall of the threaded cap 4, thereby achieving the limiting.
[0031] Specifically, firstly, the connection between the threaded cap 4 and the extension rod 1 is disengaged by rotating the threaded cap 4. The threaded cap 4, in conjunction with the external thread 5 on the extension rod 1, allows for easy disassembly. When the threaded cap 4 is removed, weight blocks 6 of different weights can be placed inside the extension rod 1 as needed. The weight of the weight block 6 can be adjusted according to personal usage habits and playing style. Then, the threaded cap 4 is reinstalled at one end of the extension rod 1. During the installation of the threaded cap 4, the screwing in of the threaded cap 4 will push the weight block 6 deeper into the extension rod 1. At this time, as the weight block 6 moves, it will apply pressure to the push plate 7, thereby causing the slide rod 9 and the limiting plate 10 to move together, ultimately causing the spring 8 to compress. The thrust generated by the spring 8 during compression ensures that the weight block 6 is firmly attached to the outer wall of the threaded cap 4, completing the limiting operation of the weight block 6. This not only enables the replacement of the weight block 6 but also ensures that the weight block 6 remains stable during use, preventing displacement or loosening of the weight block 6, thereby improving the safety and reliability of the billiard cue.
[0032] Reference Figure 1 and Figure 4 One end of the extension rod 1 is fixedly connected to a threaded post 11, and one end of the front rod 2 is provided with an internal thread 12, which can quickly and firmly connect the extension rod 1 and the front rod 2 together, ensuring the tightness and stability of the connection. One end of the extension rod 1 is fixedly connected to a rubber block 13, which is located at the connection between the extension rod 1 and the front rod 2, and serves to increase friction, reduce the slippage of the connection, and avoid problems caused by unstable connection. One end of the front rod 2 is connected to a limiting hole 14. One end of the spring 8 is fixedly connected to the inside of the extension rod 1, and the other end of the spring 8 is fixedly connected to the outer wall of the push plate 7. The outer wall of the push plate 7 is slidably connected to the inner wall of the extension rod 1. The push plate 7 is used to push the weight block 6 to move. The outer wall of the limiting plate 10 is slidably connected to the inside of the extension rod 1. The limiting plate 10 is used to limit the movement of the weight block 6. The outer wall of the rubber block 13 is slidably connected to the inside of the limiting hole 14. The limiting hole 14 is used to place the rubber block 13. The threaded cap 4 fits against the weight block 6. The threaded cap 4 is used to limit the movement of the weight block 6.
[0033] Specifically, when the threaded post 11 at one end of the extension rod 1 engages with the internal thread 12 inside the front rod 2, a stable connection can be achieved simply by rotating the extension rod 1, reducing the complexity and time-consuming assembly of traditional billiard cues. Simultaneously, during assembly, the sliding motion of the rubber block 13 at one end of the front rod 2 increases the friction between the extension rod 1 and the front rod 2, effectively preventing slippage and avoiding inconvenience or performance issues caused by unstable connections. Finally, when the extension rod 1 and the front rod 2 are fully assembled and fixed, the rubber block 13 moves into the limiting hole 14, further reinforcing the connection and ensuring that the extension rod 1 and the front rod 2 will not slip or loosen arbitrarily. The assembly and friction-enhancing structure ensures the stability of the billiard cue during use and reduces the possibility of loosening, providing a smoother and safer user experience.
[0034] Working principle: When the adjustable weight structure of the billiard cue is needed, the threaded cap 4 is first driven to rotate at one end of the extension rod 1. The threaded cap 4 can be easily installed and removed by the external thread 5. When the threaded cap 4 is removed, different weights 6 can be placed inside the extension rod 1. Then the threaded cap 4 is put back in place. During this process, the installation of the threaded cap 4 will push the weights 6 to move deeper into the extension rod 1. At this time, the movement of the weights 6 will put pressure on the push plate 7, causing the push plate 7 to drive the slide rod 9 and the limiting plate 10 to move, thereby causing the spring 8 to contract. Then, the thrust generated by the contraction of the spring 8 pushes the weights 6 to fit tightly against the outer wall of the threaded cap 4, achieving the limit. Thus, different weights of weights 6 can be replaced.
[0035] Furthermore, the threaded post 11 at one end of the extension rod 1 can be used to quickly assemble the extension rod 1 and the front rod 2 by engaging the internal thread 12 inside the front rod 2. During assembly, the rubber block 13 will slide at one end of the front rod 2, thereby increasing the friction between the extension rod 1 and the front rod 2. When the extension rod 1 and the front rod 2 are fully assembled, the rubber block 13 will move into the limiting hole 14, thus preventing the extension rod 1 and the front rod 2 from sliding freely and affecting their use.
[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
