Description

Technical Field

[0001] This utility model belongs to the field of billiard cue technology, specifically relating to a core structure of the back handle of a billiard cue. Background Technology

[0002] Billiards, as a sport and recreational activity, is very popular, especially among young people. A billiard cue is the tool used to strike the ball. A billiard cue typically consists of a tip, a ferrule, a joint, and a wedge. The tip connects to the joint via the ferrule, and the joint connects to the wedge. The quality of the wedge directly affects the effectiveness of the shot.

[0003] The existing cue handle is prone to bending or even breakage due to external factors, reducing its service life. Therefore, its defects are quite obvious. Chinese utility model patent application number 2021212696461 discloses a cue handle structure. While it effectively resists the bending resistance of the cue handle from external factors and extends its service life, its technical effects reveal that it still suffers from the problem of individual carbon fiber strips being easily damaged. The multiple carbon fiber strips are in a separate structure, which, although convenient for installation and disassembly, also incurs costs, and the overall structure has a certain degree of complexity.

[0004] Therefore, this application proposes a core structure for the back of a billiard cue to solve the aforementioned technical problems. Utility Model Content

[0005] The purpose of this utility model is to provide a core structure for the back of a billiard cue, which solves the technical problems of how to avoid damage to the billiard cue and make it easy to replace, saves the cost of subsequent installation and disassembly, simplifies the design compared with the prior art, and enhances the feel and transmission force of the cue, thereby increasing the consumer's experience and enjoyment.

[0006] A billiard cue back core structure includes a cue and a sleeve fitted on the outside of the cue;

[0007] The cue stick includes a carbon fiber strip and a wooden sandwich structure that is fixedly installed on both sides of the carbon fiber strip.

[0008] The wood sandwich structure includes a carbon fiber strip one that is vertically fixed to the carbon fiber strip two at one end, and wood strips that are respectively attached and fixed on both sides of the carbon fiber strip one. The wood strips are attached and fixed on the carbon fiber strip two.

[0009] The two wooden strips are axially symmetrical about the center line of the carbon fiber strip.

[0010] The two carbon fiber strips are axially symmetrical about the center line of the carbon fiber strip.

[0011] The wooden strips on both sides of the carbon fiber strip are axially symmetrical about the center line of the carbon fiber strip.

[0012] Both the first carbon fiber strip and the second carbon fiber strip are rectangular parallelepipeds. The outer side of the first carbon fiber strip is an arc surface, and its center is the center of the sleeve.

[0013] The two small faces of the carbon fiber strip are arc surfaces, and their centers are the center of the sleeve.

[0014] The second carbon fiber strip is glued to the first carbon fiber strip, and the wooden strip is glued to the second carbon fiber strip and the first carbon fiber strip;

[0015] The outer sides of the first carbon fiber strip, the second carbon fiber strip, and the wooden strip are all glued to the inner side of the sleeve.

[0016] The lengths of the first carbon fiber strip and the second carbon fiber strip are 50-760 mm.

[0017] The positive effects of this utility model are as follows:

[0018] (1) This utility model adopts a structure of two short and one long carbon fiber strips interlaced, which glues the wood of 1 / 4 cylinder together, enhances the stability of the cue stick, effectively resists the influence of external factors on the bending resistance of the cue stick, prevents the cue stick from bending or even breaking, and increases the strength and toughness of the cue stick as well as the transmission of force.

[0019] (2) The present invention has a simple structure. Multiple carbon fiber strips are glued to the wooden strips, which can effectively resist the bending resistance of the billiard cue handle due to external factors such as weather changes, air humidity, and placement location, prevent the billiard cue handle from bending or even breaking, and extend the service life of the billiard cue handle. Although the multiple carbon fiber strips and wooden strips are separate structures, the combination of glue and sleeve sealing makes them less prone to damage and replacement, and can be used for a long time.

[0024] To more clearly illustrate the technical features of this solution, the following detailed implementation method will be used to explain the solution.

[0025] See Figures 1-3 A billiard cue back core structure includes a cue and a sleeve 1 fitted on the outside of the cue;

[0026] The cue stick consists of a carbon fiber strip and a wooden core structure that is fixedly installed on both sides of the carbon fiber strip.

[0027] The wood sandwich structure includes a carbon fiber strip 2 that is vertically fixed to a carbon fiber strip 4 at one end, and wood strips 3 that are respectively attached and fixed on both sides of the carbon fiber strip 2. The wood strips 3 are attached and fixed on the carbon fiber strip 4.
