Description

Technical Field

[0001] The utility model relates to the technical field of sports equipment, in particular to a billiard cue composed of multiple pieces. Background Art

[0002] At present, the quality of the cue structure directly affects the hitting effect. Traditional cue is made of various logs. Although it is convenient, there are many bending phenomena caused by the irregular texture of the wood itself. Moreover, the expansion and contraction and bending of the wood itself are difficult to control, which has a great impact during use, greatly reducing the performance and quality of the cue. Although the patent document with application number CN200420048952.2 discloses a billiard cue, it is composed of a rod body, a central axis hole is opened on the central axis of the rod body along its length direction, and a rod core is arranged in the central axis hole. The rod core is a fiber rod or a wooden rod covered with a fiber layer, and the rod body is formed by symmetrically laminating two identical wooden strips. Although the patent document ensures the mechanical strength of the rod body by coating the core with fiber material, making the rod body not easy to deform or break, the fiber structure inside natural wood is not balanced and symmetrical, and the rod body is made of two identical wooden strips symmetrically bonded together. The bonding point of the two wooden strips is not convenient for evenly dispersing and transmitting the internal stress of the billiard cue. Therefore, when it is made into a cue, the elasticity and rigidity at various angles of the circumference will vary with the different structures of the billiard cue. Therefore, when hitting the ball with the above-mentioned billiard cue, the force applied to the ball is not balanced, and the ball control is poor. Summary of the invention

[0030] The multi-piece billiard cue of the utility model has a simple structure. The forelimb 2 is composed of a plurality of splicing pieces 4 arranged in sequence along the circumferential direction, and the cross section of each splicing piece 4 is triangular or fan-shaped, and the splicing piece 4 extends from the outer circumference of the forelimb 2 to the central axis of the forelimb 2 along the radial direction of the forelimb 2 to form a cylinder of the forelimb 2, that is, the fitting parts between the plurality of splicing pieces 4 are evenly distributed, and the internal stress can be evenly dispersed and transmitted. In this way, when the billiard cue of the utility model is used to hit the ball, the force at each angle of the circumference of the forelimb 2 is in a balanced state, which can improve the accuracy of the hitting, increase the hitting force, and is not easy to bend and deform, and can also extend the service life.

[0031] Furthermore, the cross-sectional areas of the plurality of splicing pieces 4 are equal, that is, the plurality of identical splicing pieces 4 are arranged in sequence along the circumferential direction, and the plurality of identical splicing pieces 4 are evenly and symmetrically distributed, so that the internal stress can be evenly dispersed and transmitted, thereby increasing the hitting force.

[0032] Furthermore, each of the splicing pieces includes a first splicing block 41, a reinforcing plate 6, and a second splicing block 42 which are sequentially connected along the radial direction of the forelimb 2. The reinforcing plate 6 is used to improve the mechanical degree of the billiard cue. A plurality of the first splicing blocks 41 are sequentially arranged along the circumferential direction, a plurality of the second splicing blocks 42 are sequentially arranged along the circumferential direction, a plurality of the reinforcing plates 6 are sequentially arranged along the circumferential direction, the inner side of the reinforcing plate 6 is connected to the outer side of the corresponding first splicing block 41, and the outer side of the reinforcing plate 6 is connected to the inner side of the corresponding second splicing block 42. That is, each splicing piece 4 is sequentially provided with a first splicing block 41, a reinforcing plate 6, and a second splicing block 42 from the inside to the outside along the radial direction of the forelimb 2, and the reinforcing plate 6 is provided between the first splicing block 41 and the second splicing block 42, so that the billiard cue is not easily deformed or broken. A plurality of the first splicing blocks 41 are arranged in sequence along the circumferential direction, a plurality of the second splicing blocks 42 are arranged in sequence along the circumferential direction, and a plurality of the reinforcing plates 6 are arranged in sequence along the circumferential direction, so that the internal stress of the first splicing block 41 can be evenly transmitted to the second splicing block 42 through the reinforcing plate 6, with good force transmission, strong hitting force, and accurate direction of hitting the target ball.

[0033] In the present embodiment, the cross section of the first splicing block 41 is triangular or fan-shaped, the cross section of the second splicing block 42 is trapezoidal or fan-ring, and the cross section of the reinforcing plate 6 is trapezoidal or fan-ring, that is, when the cross section of the first splicing block 41 is triangular, the cross section of the second splicing block 42 is trapezoidal, and the cross section of the reinforcing plate 6 is trapezoidal; when the cross section of the first splicing block 41 is fan-shaped, the cross section of the second splicing block 42 is fan-ring, and the cross section of the reinforcing plate 6 is fan-ring, the configuration is such that the outer side surface of the first splicing block 41 and the inner side surface of the reinforcing plate 6 match each other, the first splicing block 41 and the reinforcing plate 6 are firmly connected, the inner side surface of the second splicing block 42 and the outer side surface of the reinforcing plate 6 match each other, and the second splicing block 42 and the reinforcing plate 6 are firmly connected, so that the force transmission effect among the first splicing block 41, the reinforcing plate 6 and the second splicing block 42 is good.

[0034] Furthermore, the reinforcing plate 6 is a carbon fiber cloth layer or a glass fiber cloth layer. The carbon fiber cloth layer and the glass fiber cloth layer have high mechanical properties, which can improve the mechanical properties of the billiard cue and make the billiard cue less likely to deform and break.

[0035] Furthermore, the front end of the forelimb 2 is provided with a screw hole 21 along the axial direction, and the rear end of the handle 1 extends a screw rod 11 into the screw hole 21. The screw rod 11 is inserted into the screw hole 21, which is convenient for disassembly and not easy to bend and deform. In this embodiment, the screw rod 11 is threadedly connected to the screw hole 21, and the connection is stable.

Such an arrangement makes the splicing piece 4 not easy to deform and break, and the structure is simple. At the same time, the number of splicing pieces 4 and the number of reinforcing plates 6 are the same, so that the multiple splicing pieces 4 and the reinforcing plates 6 are evenly and symmetrically distributed, and the internal stress can be evenly dispersed and transmitted, which can improve the accuracy of hitting the ball and make the hitting force strong.

[0038] In this embodiment, the cross-sectional area of ​​each splicing piece 4 is equal, and the cross-section of each splicing piece 4 is triangular or fan-shaped, and the cross-section of each reinforcing plate 6 is rectangular or fan-shaped, that is, multiple splicing pieces 4 and reinforcing plates 6 are arranged in sequence along the circumferential direction to form a cylinder of the forelimb 2, which is easy to assemble.

One end of the plug-in board 5 is plugged into the first groove 43 of one splicing piece 4, and the other end of the plug-in board 5 is plugged into the second groove 44 of the adjacent splicing piece 4. A plurality of the plug-in boards 5 are distributed in a ring array. The plug-in board 5 is used to improve the mechanical degree of the splicing piece 4, and also makes the connection between two adjacent splicing pieces 4 stable and practical. At the same time, the plurality of the plug-in boards 5 are distributed in a ring array, that is, the plurality of the plug-in boards 5 are evenly and symmetrically distributed, so that when the billiard cue is used to hit the ball, the power of each plug-in board 5 is equal, which can improve the accuracy of the shot.

[0041] In this embodiment, the plug board 5 is a carbon fiber cloth layer or a glass fiber cloth layer. The carbon fiber cloth layer and the glass fiber cloth layer have high mechanical properties, which can improve the mechanical properties of the billiard cue and make the billiard cue less likely to deform and break.

[0042] Furthermore, the plug-in board 5 is a rectangular plate, and the plug-in board 5 is perpendicular to the radial direction of the forelimb 2. In this embodiment, the plug-in board 5 includes a first board surface, a second board surface opposite to the first board surface, and two sets of opposite side walls between the first board surface and the second board surface, and has a simple structure and is not easy to bend and deform. The side wall of the plug-in board 5 is plugged into the first groove 43 of a splicing piece 4, and the other side wall of the plug-in board 5 is plugged into the second groove 44 in the adjacent splicing piece 4, that is, the plug-in board 5 is perpendicular to the radial direction of the forelimb 2, so that more plug-in boards 5 can be embedded in the splicing piece 4, so that the splicing piece 4 is not easy to deform, not easy to break, and the service life is extended, and the connection is stable.

[0043] Example 4

[0044] like Figure 7-8 As shown, different from the embodiment 3, the plug-in board 5 is a rectangular board, and the plug-in board 5 is arranged along the radial direction of the forelimb 2, with a simple structure and not easy to bend and deform.
