Description

Technical Field

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

[0002] When striking the ball, the buttstock (front section) of the billiard cue bears the force first. Since the diameter of the buttstock is usually small, it requires high hardness and strength to ensure a good feel and prevent breakage. Currently, the buttstock is typically made from a single piece of wood. However, the density of different sections of wood varies, leading to inconsistent quality in the finished buttstock. Furthermore, the wood's structure is easily affected by external conditions such as weather changes, humidity, and placement, making it prone to damage and reduced force transmission. Utility Model Content

[0003] In view of the problems existing in the prior art, the purpose of this utility model is to provide a tailstock structure for billiard cues that can make the quality of the tailstock more uniform and has better hardness, force transmission and feel feedback.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A billiard cue tailstock structure includes a tailstock body, the large end of which has a first elongated hole extending along its length, and the small end of which has a second elongated hole extending along its length, both the first and second elongated holes being blind holes; a first carbon fiber tube is inserted into the first elongated hole, and the first carbon fiber tube abuts against the bottom of the first elongated hole; a balsa wood post is inserted into the second elongated hole, one end of the balsa wood post abuts against the bottom of the second elongated hole, and the other end of the balsa wood post is flush with the opening of the second elongated hole.

[0006] The diameter of the first elongated hole is larger than that of the second elongated hole. This design can further reduce the weight ratio of the tailstock body wood, thereby making the weight of the tailstock more uniform.

[0007] The outer diameter of the first carbon fiber tube is matched with the diameter of the first elongated hole; the outer diameter of the balsa wood column is matched with the diameter of the second elongated hole. This arrangement ensures that the first carbon fiber tube supports the wall of the first elongated hole, and that the balsa wood column supports the wall of the second elongated hole.

[0008] The second elongated hole also contains a second carbon fiber tube, which abuts against the balsa wood post. The second carbon fiber tube is positioned closer to the larger end of the tailpiece body, while the balsa wood post is positioned closer to the smaller end of the tailpiece body. This arrangement allows the balsa wood post to be shorter to ensure a better feel when hitting the ball. Correspondingly, the depth of the first elongated hole can also be made longer. By inserting the second carbon fiber tube, the strength of the tailpiece body segment corresponding to the second elongated hole can be increased.

[0009] The outer diameter of the second carbon fiber tube is matched with the diameter of the second elongated hole. This arrangement ensures that the second carbon fiber tube provides support for the wall of the second elongated hole.

[0010] There is a gap between the bottom of the first elongated hole and the bottom of the second elongated hole.

[0011] By adopting the above solution, this utility model, through setting a first elongated hole and a second elongated hole, and inserting a first carbon fiber tube into the first elongated hole, can ensure the strength and hardness of the tail shaft body corresponding to the segment with the first elongated hole. Similarly, inserting a balsa wood post into the second elongated hole can also ensure the strength of the tail shaft body corresponding to the segment with the second elongated hole, thereby guaranteeing the force transmission performance of the tail shaft. The balsa wood post in this utility model can also absorb shock, improve the force transmission path during impact, enhance the hitting feel, and make the hitting feel more consistent.

[0015] Tail rod body 1; first elongated hole 2; second elongated hole 3; first carbon fiber tube 4; balsa wood post 5; second carbon fiber tube 6; tip 7. Detailed Implementation

[0016] The present invention will now be described with reference to the accompanying drawings.

[0017] Example 1

[0018] like Figure 1 As shown in the figure, this embodiment discloses a tailstock structure for a billiard cue, which includes a tailstock body 1. The larger end (the end with the larger diameter) of the tailstock body 1 has a first elongated hole 2 extending along its length, and the smaller end (the end with the smaller diameter) of the tailstock body 1 has a second elongated hole 3 extending along its length. The first elongated hole 2, the second elongated hole 3, and the tailstock body 1 are coaxially arranged. Both the first elongated hole 2 and the second elongated hole 3 are blind holes, and the diameter of the first elongated hole 2 is larger than the diameter of the second elongated hole 3. There is a gap between the bottom of the first elongated hole 2 and the bottom of the second elongated hole 3, preferably not less than one-twentieth of the length of the tailstock body 1.

[0019] A first carbon fiber tube 4 is inserted into the first elongated hole 2. The outer diameter of the first carbon fiber tube 4 is adapted to the diameter of the first elongated hole 2. One end of the first carbon fiber tube 4 abuts against the bottom of the first elongated hole 2, and the other end of the first carbon fiber tube 4 can extend out of the opening of the first elongated hole 2 for connection with the front shaft of the billiard cue.

[0020] A balsa wood post 5 is inserted into the second elongated hole 3. The outer diameter of the balsa wood post 5 is adapted to the diameter of the second elongated hole 3, and one end of the balsa wood post 5 abuts against the bottom of the second elongated hole 3, while the other end of the balsa wood post 5 is flush with the opening of the second elongated hole 3, forming a plane for installing the rubber head 7. The balsa wood post 5 is a solid body.

[0021] Example 2

[0022] like Figure 2 As shown, the difference between this embodiment and Embodiment 1 is that the second elongated hole 3 is deepened, but the distance between the bottom of the first elongated hole 2 and the bottom of the second elongated hole 3 is still required to be no less than one-twentieth of the length of the tail rod body 1. In addition, a second carbon fiber tube 6 is inserted into the second elongated hole 3, and the outer diameter of the second carbon fiber tube 6 matches the diameter of the second elongated hole 3. This second carbon fiber tube abuts against the balsa wood post, and the second carbon fiber tube is positioned closer to the larger end of the tail rod body, while the balsa wood post is positioned closer to the smaller end of the tail rod body.

[0023] The key to this invention lies in its ability to reduce the weight proportion of wood in the tailstock body 1 by setting the first elongated hole 2 and the second elongated hole 3, thereby making the weight of the tailstock more uniform. By inserting the first carbon fiber tube 4 into the first elongated hole 2, the strength and rigidity of the segment of the tailstock body 1 corresponding to the first elongated hole 2 can be ensured, improving the force transmission performance of the tailstock. Simultaneously, inserting the balsa wood post 5 into the second elongated hole 3 also ensures the strength of the segment of the tailstock body 1 corresponding to the second elongated hole 3. The balsa wood post 5 serves to absorb shock and improve the force transmission path during impact, enhancing the feel of the shot and making the feel of the shot more consistent.

[0024] The above description is merely an embodiment of the present utility model and does not constitute any limitation on the technical scope of the present utility model. Therefore, any minor modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model shall still fall within the scope of the technical solution of the present utility model.
