Description

Technical Field

[0001] The utility model relates to the field technology of billiard cue nose angle, in particular to a billiard cue nose angle structure with a barb. Background Art

[0002] With the development of society and the improvement of people's living standards, leisure sports have become increasingly popular and an important part of people's cultural life. Leisure sports not only relieve stress and relax excessive tension, but also promote individuality and the pursuit of taste and interest. Billiards is a very popular leisure sport.

[0003] Billiards, also known as table tennis or pinball, is a ball sport. It's a recreational sport in which players use a cue longer than 91.4 cm to strike the cue ball against the target ball according to certain rules. Billiards requires a billiard cue, a striking tool made of high-quality wood or carbon fiber. The cue tapers in front and thickens in the back, and can be either long or short. Generally, a cue should be no shorter than 91 cm. A cue that's too long is difficult to control and affects both aiming and hitting, so it's important to choose a cue that suits your needs. The cue is round, tapering in front and thickening in the back, and is straight. The length ranges from 1.3 to 1.5 meters, with a cue head (the thin end) diameter of approximately 9 to 12 mm. A billiard cue consists of a tip, horn, front section, upper ring, middle wheel, lower ring, back section, grip, and rubber tip.

[0004] Current billiard cue horns generally consist of a body and a protrusion. The protrusion extends outward from one end of the body and is inserted into a through-hole at the front end of the horn. The hollow cavity of the horn is filled with PU foam. Although this structure is simple, it suffers from poor structural stability. Over time or when subjected to external force, the horn can easily fall off the horn, resulting in poor product quality, a short service life, and a poor user experience, which cannot meet current needs. Therefore, it is necessary to develop a new technical solution to improve the above-mentioned problems. Utility Model Content

[0005] In view of this, the present invention aims to address the deficiencies in the prior art, and its main purpose is to provide a billiard cue nose structure with a barb, which can effectively solve the problems in the prior art of poor stability of the connection structure between the nose of the billiard cue and the PU foam in the front section, the nose easily falling off from the front section after long-term use or when subjected to external force, resulting in poor product quality, short service life, and poor user experience.

[0006] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0007] A billiard cue nose structure with a barb comprises a body, a boss and a barb; the boss extends outward from one end surface of the body, and the outer diameter of the boss is smaller than that of the body; the barb extends outward from the tail end of the boss, and the outer diameter of the barb is smaller than that of the boss.

[0008] As a preferred embodiment, the barb includes a main body and a boss that are integrally connected. The main body extends outward from the tail end of the boss. The boss is arranged at the tail end of the main body. The outer diameter of the boss is larger than the outer diameter of the main body, and the outer diameter of the boss is smaller than the outer diameter of the boss.

[0009] As a preferred solution, the main body is a cylindrical structure.

[0010] As a preferred solution, the boss is a cylindrical structure.

[0011] As a preferred solution, the tail end of the boss is provided with a chamfer, which can effectively increase the bonding area, make the product bonded more firmly, and improve the quality of the product.

[0012] As a preferred solution, the boss is a cylindrical structure, and the boss is embedded in one end of the front section of the billiard cue with a hollow structure and is adapted to the one end of the front section of the billiard cue.

[0013] As a preferred solution, the outer side surface of the convex column is provided with a plurality of grooves for increasing the bonding area.

[0014] As a preferred solution, the groove is an annular groove, which further increases the bonding area and enhances the stability of the connection structure.

[0015] As a preferred solution, the multiple grooves are evenly spaced axially on the outer side surface of the boss, further increasing the bonding area and enhancing the stability of the connection structure.

[0016] As a preferred solution, the other end surface of the body is provided with a bump for increasing the bonding area with the leather head.

[0017] Compared with the prior art, the present invention has obvious advantages and beneficial effects. Specifically, it can be seen from the above technical solution that:

[0018] By setting a front corner including a main body, a boss and a hook, the boss is extended outward from one end surface of the main body, and the outer diameter of the boss is smaller than the outer diameter of the main body, and the hook is extended outward from the tail end of the boss, and the outer diameter of the hook is smaller than the outer diameter of the boss. The front corner of this structure can effectively enhance the contact area between the front corner and the PU foam filled in the front section by setting the hook, thereby increasing the bonding area between the front corner and the PU foam, and enhancing the stability of the front corner installed and fixed in the hollow cavity of the front section. The hook can increase the pulling force of the PU foam on the front corner. Even if it is used for a long time or is impacted by external force, the front corner is not easy to fall off from the front section, which greatly improves the quality of the product, extends the service life of the product, enhances the user experience, and meets existing needs.

[0019] In order to more clearly illustrate the structural features and effects of the present invention, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments. BRIEF DESCRIPTION OF THE DRAWINGS
