Description

Technical Field

[0001] The utility model relates to a billiard table, in particular to a rubber edge structure of a billiard table. Background Technique

[0002] A billiard table mainly consists of structures such as table legs, a tabletop, an upper rail, and ball holes. The upper rail consists of structures such as a side rail, a cushion, and a rubber edge. The rubber edge is located on the innermost side of the upper rail. When the hit billiard ball rolls to the edge of the table, the billiard ball touches the rubber edge, and the rubber edge can play a role in rebounding the touched billiard ball. The rubber edges produced by the existing technology are usually strip-shaped, with an L-shaped cross-section, and the structure of the whole rubber edge is the same (as shown in the attachment Figure 10 ). During installation, the rubber edge is adhered to the inner wall of the cushion with glue. When fitting to the position of the ball hole, the rubber edge needs to be curved and fitted in an arc shape, and then the worker holds a tool to cut and polish the rubber edge at the ball hole to make the ball hole reach the standard size (the diameter at the ball hole needs to be between 85 mm and 95 mm, and the rubber edge at the ball hole needs to have a circular arc transition, which is beneficial for the ball to enter the hole). This structure of the rubber edge requires secondary processing by workers. Firstly, it leads to a reduction in production efficiency. Secondly, it has a high requirement for the proficiency of workers. Moreover, manual secondary processing has low precision and is prone to errors. Summary of the Invention

[0003] The purpose of the utility model is to overcome the shortcomings of the existing technology and provide a rubber edge structure of a billiard table that does not require secondary processing by workers, is convenient for installation, improves production efficiency, has high precision, and has a simple structure.

[0004] The technical solution of a rubber edge structure of a billiard table of the utility model is: it includes a rubber edge main body, and arc-shaped fitting parts are integrally formed at both ends of the rubber edge main body respectively.

[0005] Further, the angle θ between the inner wall of the arc-shaped fitting part and the inner wall of the rubber edge main body 1 is 133° - 138°, and the angle θ between the outer wall of the arc-shaped fitting part and the outer wall of the rubber edge main body 2 is 139° - 143°.

[0006] Further, the wall thickness of the arc-shaped fitting part gradually becomes thinner from its root to its head.

[0007] Further, a protruding part is made on the outer wall of the rubber edge main body.

[0008] Further, a right-angle groove or an inclined plane or a concave arc surface is made between the rubber edge main body and the protruding part.

[0009] Further, the cross-section of the rubber edge main body is triangular, or a groove is made on the hypotenuse side of the triangular rubber edge main body.

[0010] The utility model provides a billiard table rubber edge structure with the following beneficial effects: the arc-shaped fitting part and the rubber edge body are integrally manufactured and formed, and no secondary processing is required by workers when the rubber edge body is located at the ball hole mouth. The structure is simple and the installation is convenient, thereby effectively improving production efficiency and reducing the labor intensity of workers. In addition, the mold is directly used for manufacturing and forming, so the manufactured products are uniform and have high product precision, and the proficiency requirements for workers are low during installation.

[0021] The utility model relates to a rubber edge structure of a billiard table, such as Figure 1 — Figure 9 As shown, it comprises a rubber edge body 1, and both ends of the rubber edge body 1 are respectively provided with an integrally formed arc-shaped fitting portion 2.

[0022] Furthermore, the angle θ between the inner wall of the arc-shaped fitting portion 2 and the inner wall of the rubber edge body 1 is 1 The angle θ between the outer wall of the arc-shaped fitting portion 2 and the outer wall of the rubber edge body 1 is 133°-138°. 2is 139° - 143°. The angle θ between the inner wall of the arc-shaped fitting part 2 and the inner wall of the rubber edge main body 1 1 is set to 133° - 138°. When the arc-shaped fitting part 2 is fitted to the arc-shaped corner position of the library edge, the radian is the same and the fitting is smooth; the angle θ between the outer wall of the arc-shaped fitting part 2 and the outer wall of the rubber edge main body 1 2 is set to 139° - 143°, so that the size and radian of the ball hole reach the standard, which is beneficial to scoring goals.

[0023] Furthermore, the wall thickness of the arc-shaped fitting part 2 gradually becomes thinner from its root 3 to its head 4. The root 3 of the arc-shaped fitting part 2 is located at one end of the rubber edge main body 1 and is integrally connected to the rubber edge main body, so the thickness of the root 3 is the same as that of the rubber edge main body 1. The head 4 of the arc-shaped fitting part 2 is far from the rubber edge main body 1, and the thickness gradually becomes thinner from the root 3 to the head 4, so that the hole size formed between two adjacent arc-shaped fitting parts 2 reaches the standard.

[0024] Furthermore, a protruding part 5 is formed on the outer wall of the rubber edge main body 1. The rubber edge main body 1 with this structure is mainly applicable to the billiard table for Chinese billiards.

[0025] Furthermore, a right-angle groove 6 or an inclined surface 7 or a concave arc surface 8 is formed between the rubber edge main body 1 and the protruding part 5.

[0026] Furthermore, the cross-section of the rubber edge main body 1 is triangular, or a groove 9 is formed on the hypotenuse side of the triangular rubber edge main body. The rubber edge main body 1 with this structure is mainly applicable to the billiard table for English billiards.

[0027] The utility model discloses a rubber edge structure of a billiard table. The upper structure of the billiard table includes a rectangular tabletop 11. Two sections of small side rails 12 are respectively arranged on the upper parts of the long sides of the rectangular tabletop 11, and one section of small side rail 12 is respectively arranged on the upper parts of the wide sides of the rectangular tabletop 11. Cushions 13 are arranged on the inner walls of the respective small side rails 12, and corresponding rubber edges are arranged on the inner walls of the respective cushions 13. The upper side rails are composed of the small side rails 12, the cushions 13 and the rubber edges. Ball holes 14 are formed between the respective sections of the upper side rails. Ball pockets 15 are made in the ball holes 14. Mainly, arc-shaped fitting parts 2 are made at positions corresponding to the ball holes 14 at both ends of the rubber edge main body 1. The arc-shaped fitting parts 2 and the rubber edge main body 1 are integrally formed by an extrusion mold. During installation, the rubber edge main body 1 is adhesively fixed to the side wall of the cushion 13 through an adhesive. The inner wall of the arc-shaped fitting part 2 fits with the arc surfaces at both ends of the cushion 13. The arc-shaped fitting part 2 is curved inwards in an arc shape, and its wall thickness gradually decreases from its root 3 to its head 4, and the angle between its outer wall and the outer wall of the rubber edge main body 1 is 139° - 143°. The ball hole 14 formed between two adjacent arc-shaped fitting parts 2 reaches a standard size of 85 mm - 95 mm. Therefore, the installation can be completed without secondary processing of this position by workers. For a rubber edge structure of a billiard table in this solution, the arc-shaped fitting part 2 and the rubber edge main body 1 are integrally formed. There is no need for secondary processing by workers at the position of the ball hole 14 on the rubber edge main body 1. The structure is simple and the installation is convenient, so that the production efficiency can be effectively improved, the labor intensity of workers can be reduced, and the products are directly formed by a mold. The manufactured products are unified and have high product precision, and the proficiency requirements for workers during installation are low.
