Description

Technical Field

[0001] This utility model relates to the field of billiard cue structure technology, specifically a billiard cue forelimb that is simple in structure, beautiful in appearance, seamless, high in strength, and has good striking force characteristics. Background Technology

[0002] As is well known, a billiard cue is usually composed of a forelimb and a butt. The forelimb, as the main striking part, is generally made of solid wood, making it relatively heavy, prone to deformation, and lacking in hardness. It also has poor striking force characteristics (tension and elasticity) and impact absorption characteristics. To solve these problems, the forelimb of existing billiard cues is made of carbon fiber. However, existing carbon fiber billiard cues have obvious seams and are not aesthetically pleasing. Moreover, carbon fiber has a tubular structure, which, although strong, has poor striking force characteristics. Summary of the Invention

[0003] The purpose of this utility model is to overcome the shortcomings of the prior art and provide a billiard cue forelimb that is simple in structure, beautiful in appearance, seamless, high in strength, and has good striking force characteristics.

The filling core layer is a conical rod shape, and the carbon fiber inner reinforcement layer is wrapped around the outside of the filling core layer. The carbon fiber inner reinforcement layer is formed by wrapping the conical rod-shaped filling core layer with a trapezoidal pre-impregnated carbon fiber cloth. The shaping tape layer is wrapped around the outside of the carbon fiber inner reinforcement layer. The shaping tape layer is formed by wrapping the shaping tape around the outside of the carbon fiber inner reinforcement layer. The carbon fiber outer reinforcement layer is wrapped around the outside of the shaping tape layer.

Detailed Implementation

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] As shown in the attached figure, a billiard cue forelimb is characterized in that the forelimb of the billiard cue includes a filling core layer 1, a carbon fiber inner solid layer 2, a shaping tape layer 3, a carbon fiber outer solid layer 4, a front plug 5, and a rear plug 6. The filling core layer 1 is a conical rod shape, and the carbon fiber inner solid layer 2 is wrapped around the outside of the filling core layer 1. The carbon fiber inner solid layer 2 is formed by wrapping the conical rod-shaped filling core layer 1 with a trapezoidal pre-impregnated carbon cloth. The shaping tape layer 3 is wrapped around the outside of the carbon fiber inner solid layer 2. The shaping tape layer 3 is formed by wrapping the shaping tape around the outside of the carbon fiber inner solid layer 2. The carbon fiber outer solid layer 4 is wrapped around the outside of the shaping tape layer 3. The carbon fiber outer solid layer 4 is formed by wrapping the pre-impregnated carbon fiber tape around the outside of the shaping tape layer. The outside of the carbon fiber outer solid layer 4 is polished to form a smooth outer wall. The front and rear ends of the tubular structure formed by the carbon fiber inner solid layer 2, the shaping tape layer 3, and the carbon fiber outer solid layer 4 are respectively sealed inside the carbon fiber inner solid layer 2 by the front plug 5 and the rear plug 6.

[0023] Furthermore, the rear plug 6 is provided with a connection hole 7 for connecting to the rear leg of the billiard cue.

[0024] Furthermore, the filling core layer 1 is filled with foam or a wooden rod.

[0025] Furthermore, the filling core layer is filled by mixing wood chips and adhesive.

[0026] Furthermore, the carbon fiber inner solid layer 2 includes multiple trapezoidal prepreg carbon cloths, which include vertical straight filament carbon cloths and oblique filament carbon cloths, and the vertical straight filament carbon cloths and oblique filament carbon cloths are wrapped sequentially or alternately.

[0027] Furthermore, the multi-layer trapezoidal prepreg carbon cloth also includes transverse straight filament carbon cloth, vertical straight filament carbon cloth, transverse straight filament carbon cloth and oblique filament carbon cloth wrapped sequentially or alternately.

[0028] Furthermore, the oblique carbon cloth includes left-directed oblique carbon cloth and right-directed oblique carbon cloth, which are wrapped sequentially or alternately with vertical straight carbon cloth.

[0029] Furthermore, the shaping layer 3 is formed by winding BOPP tape.

[0030] Furthermore, the carbon fiber outer layer 4 is a pre-impregnated carbon fiber strip, which is formed by sequentially stacking and winding the thin end of the billiard cue towards the thick end or the thick end towards the thin end.

[0031] Furthermore, the width of the prepreg carbon fiber tape is 2-7 mm.

[0032] Furthermore, the stack width of the prepreg carbon fiber tapes stacked and wound in sequence is 0.5-0.8 times the width of the prepreg carbon fiber tapes.

[0033] In manufacturing this invention, firstly, a mandrel with a consistent taper of the billiard cue's forelimb is selected. Then, a trapezoidal pre-impregnated carbon fiber cloth is taken and wrapped around the outside of the mandrel. Multiple layers of trapezoidal pre-impregnated carbon fiber cloth are wrapped sequentially to form a carbon fiber inner solid layer 2. Next, BOPP tape is wrapped around the outside of the carbon fiber inner solid layer 2, forming a shaping tape layer 3. Finally, pre-impregnated carbon fiber tape is wrapped around the outside of the shaping tape layer 3. The pre-impregnated carbon fiber tape is formed by stacking and winding the pre-impregnated carbon fiber tape sequentially from the thinner end to the thicker end of the billiard cue's forelimb. The pre-impregnated carbon fiber tape is wound into layers to form the outer carbon fiber layer 4. The entire wound structure is then moved to a curing device for heating and curing. After curing, the core rod is extracted to form the entire carbon fiber tubular structure. One end of the tubular structure is closed and filled into the filling structure with foam or a mixture of wood chips and adhesive. The tubular structure is then placed on a sander to smooth the outer wall. Finally, the front plug 5 and the rear plug 6 are fixed to the front and rear ends of the tubular structure, respectively. A connection hole 7 is opened on the thickness head, and a threaded tube connected to the rear limb is inserted into the connection hole 7.

[0034] In the process of the above manufacturing method, during the wrapping of multiple trapezoidal prepreg carbon cloth, vertical straight carbon cloth and oblique carbon cloth can be wrapped sequentially or alternately. During the wrapping of oblique carbon cloth, left oblique carbon cloth and right oblique carbon cloth can be wrapped sequentially or alternately with vertical straight carbon cloth respectively.

[0035] Because of the use of the above-mentioned carbon fiber combined tubular structure, the strength of the rod can be guaranteed, while also ensuring an aesthetically pleasing overall appearance without any seam marks. In addition, because the tubular structure is filled with foam, wood rod, or a mixture of wood chips and adhesive, the striking force characteristics of the rod are good. This utility model has the advantages of simple structure, beautiful appearance, no seam marks, high strength, and good striking force characteristics due to the above structure.
