Description

Technical Field

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

[0002] The cue tip is the core component of a billiard cue, being the only part that contacts the cue ball. Its quality and performance significantly impact the shot's effectiveness. Finding a cue tip that suits your skill level greatly helps improve your game. Traditional cue tips are made of thick cowhide and are a single, one-piece construction; however, because the quality of each cow's hide varies, it's largely a matter of luck, resulting in inconsistent tip quality. In existing patents, the applicant filed a Chinese patent application on December 23, 2019, with application number 201922354436.1, disclosing a hollow cue tip and a billiard cue with the hollow cue tip. The hollow cue tip includes a main body composed of several layers of leather stacked and pressed together. A through hole is located in the center of the main body, extending through both ends. The hollow tip increases the contact area when the ball strikes, reducing the likelihood of mis-hitting or off-target shots. Upon impact, the rebound force generated by the ball against the hollow tip is counteracted by the opposing pressure protrusions in the leather on the inner wall of the through-hole, preventing the rebound force from being transmitted to the cue stick and causing micro-vibrations, thus improving the comfort of holding the cue stick. However, the hollow tip is prone to damage and has a short lifespan. Therefore, its drawbacks are quite 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 tip.

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

[0005] A billiard cue tip includes a cylindrical inner core and a spirally wound multi-layered outer wrapping material strip covering the periphery of the inner core. Adjacent layers of the outer wrapping material strip are glued together, and the outer wall of the inner core is glued to the inner layer of the outer wrapping material strip. The inner core includes multiple layers of leather pieces stacked from top to bottom, and adjacent layers of leather pieces are connected by a resin layer.

[0006] Furthermore, the top surface of the outer wrapping strip forms an arc, which smoothly connects with the edge of the topmost leather piece.

[0007] Furthermore, the bottom surface of the outer wrapping strip is flush with the bottom layer of leather.

[0008] Furthermore, the outer wrapping material is a leather material or a fiber material.

[0009] Furthermore, the bottom surface of the top layer of leather sheet, the top surface of the bottom layer of leather sheet, and the top and bottom surfaces of the middle layer of leather sheet are all recessed with grooves, and the resin layer extends into the grooves.

[0010] Furthermore, the grooves are striped or grid-like.

[0011] Furthermore, the top surface of the top layer of leather has a rough, powder-coated surface.

[0012] Furthermore, the bottom surface of the lowest layer of leather has a glue reservoir.

[0013] Furthermore, the bottom center of the inner core is recessed upwards with an insert hole.

[0014] Furthermore, a counterweight is embedded in the mounting hole, and the depth of the mounting hole is greater than the thickness of the counterweight.

[0015] The beneficial effects of this utility model are as follows: A billiard cue tip includes a cylindrical inner core and a spirally wound, multi-layered outer wrapping material covering the periphery of the inner core. Adjacent layers of the outer wrapping material are bonded together with adhesive, and the outer wall of the inner core is bonded to the inner layer of the outer wrapping material with adhesive. The inner core includes multiple layers of leather sheets stacked from top to bottom, with adjacent layers of leather sheets connected by resin layers. This utility model achieves modular production of the cue tip. During processing, the inner core is composed of multiple layers of leather sheets and multiple layers of resin layers arranged alternately. The outer wrapping material can be pre-treated with relevant chemical solvents and chemicals to increase its roughness and elasticity. Then, the chemically treated and glued outer wrapping material is spirally wound (multiple turns) around the inner core by a machine, which increases the coefficient of friction and elasticity of the cue tip, ensuring a higher coefficient of friction and rebound when hitting the ball, increasing the hitting power and stability, and extending its service life.

[0022] 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.

[0023] like Figures 1 to 4 As shown, the present invention provides a billiard cue tip, which includes a cylindrical inner core 1 and a spirally wound multi-layered outer wrapping material 2 that covers the periphery of the inner core 1. Adjacent layers of the outer wrapping material 2 are glued together, and the outer wall of the inner core 1 is glued to the inner layer of the outer wrapping material 2. The inner core 1 includes multiple layers of leather pieces 3 stacked from top to bottom, and adjacent layers of leather pieces 3 are connected by a resin layer 4. This invention enables modular production of the cue tip. During processing, the inner core 1 is composed of multiple layers of leather sheets 3 and multiple layers of resin layers 4 spaced apart. The outer wrapping tape 2 can be pre-treated with relevant chemical solvents and chemicals to increase its roughness and elasticity. Then, the chemically treated and glued outer wrapping tape 2 is spirally wound around the inner core 1 in multiple layers (multiple turns) by a machine. This increases the friction coefficient and elasticity of the cue tip, ensuring a higher friction coefficient and rebound when hitting the ball, increasing the hitting power and stability, and extending its service life.

[0024] In this embodiment, the top surface of the outer covering strip 2 forms an arc surface 5, which smoothly connects with the edge of the topmost leather piece 3. This structural design facilitates stable ball striking with the leather tip.

[0025] In this embodiment, the bottom surface of the outer wrapping strip 2 is flush with the bottom leather piece 3, which facilitates the assembly of the leather head and the first corner 6.

[0026] In this embodiment, the outer wrapping material 2 is a leather material or a fiber material.

[0027] In this embodiment, the bottom surface of the top layer leather piece 3, the top surface of the bottom layer leather piece 3, and the top and bottom surfaces of the middle layer leather piece 3 are all recessed with grooves, and the resin layer 4 extends into the grooves. The grooves are striped or grid-like. This structural design makes the connection between the leather piece 3, the resin layer 4, and the leather piece 3 firm.

[0028] In this embodiment, the top surface of the top layer of leather sheet 3 is provided with a rough powder-gripping surface. The rough powder-gripping surface improves the powder-gripping power of the leather tip and increases the coefficient of friction when hitting the ball.

[0029] In this embodiment, the bottom surface of the bottommost leather piece 3 is provided with a glue storage groove; when the leather head and the first corner 6 are glued together, the glue storage groove can store a certain amount of glue, which improves the firmness of the connection between the leather head and the first corner 6.

[0030] In this embodiment, the bottom center of the inner core 1 is recessed with an insert hole. When the end cap and the tip 6 are assembled, the end cap is not only glued to the tip 6, but the insert post of the tip 6 is also inserted into the insert hole to provide positioning and guidance for the assembly of the end cap and the tip 6, thereby improving the positional accuracy and stability of the assembly of the end cap and the tip 6.

[0031] In this embodiment, a counterweight is embedded in the mounting hole, and the depth of the mounting hole is greater than the thickness of the counterweight. By installing the counterweight in the mounting hole, not only can it serve as a counterweight, but it can also strengthen the strength of the tip. Furthermore, by increasing or decreasing the number or weight of the counterweight, different counterweight requirements can be changed.

[0032] All technical features in this embodiment can be freely combined according to actual needs.

[0033] The above embodiments are preferred implementations of this utility model. In addition, this utility model can also be implemented in other ways. Any obvious substitutions without departing from the concept of this technical solution are within the protection scope of this utility model.
