DESCRIPTION OF THE EMBODIMENTS

The present disclosure is described in more detail hereinafter with reference to the accompanying drawings and a specific embodiment.

Embodiment

As shown in FIG. 1 and FIG. 2, in this embodiment, a split-type assembled billiard cue includes a cue rear section 1. The cue rear section 1 includes a first rod body 11, a second rod body 12, a connecting pin 10 for fixation with a cue front section 2, and a counterweight 13. The connecting pin 10 is fixed at a head end of the first rod body 11, and a tail end of the first rod body 11 is fixed with a head end of the second rod body 12. The first rod body 11 is provided therein with a placement cavity 113 extending along a length direction of the first rod body 11, and the counterweight 13 is arranged in the placement cavity 113. The counterweight 13 is configured to adjust the counterweight at the center of the billiard cue. The material or configuration of the counterweight 13 can be selected according to the requirements. For example, in this embodiment, the cylindrical counterweight 13 is adopted, and selectively, ribs 131 may be formed at intervals on the peripheral wall of the counterweight 13 along a length direction of the counterweight 13. As shown in FIG. 3, the ribs 131 extend along the circumferential direction of the counterweight 13 in an annular shape, thereby helping to hold and improving the aesthetic appearance.

The fixation of the connecting pin 10 with the head end of the first rod body 11 may be common threaded connection, embedded fixation, etc. In this embodiment, the embedded fixation structure is adopted. As shown in FIG. 5, a mounting opening 111 communicating with the placement cavity 113 is formed at the end face of the head end of the first rod body 11, and the tail end of the connecting pin 10 is embedded in the mounting opening 111. In this embodiment, the configuration of the connecting pin 10 is designed. As shown in FIG. 4, the connecting pin 10 includes, for example, a main body 102, a threaded stud 101 at a head end of the main body 102, and an insertion post 103 at a tail end of the main body 102. A shaft diameter of the main body 102 is larger than those of the threaded stud 101 and the insertion post 103. The threaded stud 101 is configured for threaded connection with the cue front section 2. The insertion post 103 is embedded and fixed in the mounting opening 111 at the head end of the first rod body 11. The structure of the connecting pin 10 is designed to facilitate assembly and abutting against the cue front section 2. Furthermore, a decorative pattern 104 may be formed at the peripheral wall of the main body 102. The specific shape of the pattern 104 may be selected as needed. In addition, a first anti-slip convex ring 105 is formed at the peripheral wall of the main body 102 behind an area where the pattern 104 is located. For example, convex strips may be distributed at interval in the circumferential direction to form the first convex ring 105, thereby facilitating holding and applying a force.

Likewise, the fixation of the counterweight in the placement cavity may be threaded connection, embedded fixation, clamped fixation, or the like. Preferably, the counterweight 13 is clamped and fixed for example. In this embodiment, the placement cavity 113 extends to the end face of the tail end of the first rod body 11, and a protrusion 114 for limiting a position is formed by radially protruding outwards at the wall of the placement cavity 113 adjacent to the opening at the tail end. The protrusion 114 extends in the circumferential direction in an annular shape. The mounting opening 111 communicating with the placement cavity 113 is formed at the end face of the head end of the first rod body 11, and the mounting opening 111 is configured for the counterweight 13 to be inserted into the placement cavity 113. For example, the diameter of the mounting opening 111 is larger than the diameter of the counterweight 13 in this embodiment. For this, the counterweight 13 may be inserted into the placement cavity 113 via the mounting opening 111 until the tail end of the counterweight 13 abuts against the protrusion 114. Moreover, the tail end of the connecting pin 10 is fixed in the mounting opening, and the tail end of the connecting pin 10 abuts against the head end of the counterweight 13. Furthermore, the tail end of the connecting pin 10 cooperates with the protrusion 114 to clamp the counterweight 13 in the placement cavity 113, thereby facilitating assembly and disassembly, as shown in FIG. 1, FIG. 2, and FIG. 3.

The abutting of the tail end of the first rod body 11 against the second rod body 12 is similarly embedded fixation, threaded connection, or the like. In this embodiment, the tail end of the first rod body 11 and the second rod body 12 are connected via embedded fixation. Specifically, for example, the second rod body 12 is cylindrical, and the tail end of the first rod body 11 is embedded and fixed in the first cylindrical opening 123 at the head end of the second rod body 12, as shown in FIG. 1 and FIG. 2.

In order to improve the aesthetic appearance, in this embodiment, decorative holes 110 communicating with the placement cavity 113 are formed at intervals at the peripheral wall of the first rod body 11. As shown in FIG. 5, the decorative holes 110 have an arc-shaped configuration for example, and are distributed at intervals along the peripheral wall of the first rod body 11, thereby improving the aesthetic appearance. Furthermore, decorative grooves 122 are distributed at intervals at the peripheral wall of the tail end of the second rod body 12. A depth of the decorative grooves 122 may be selected as needed, such as communicating or not communicating with the cavity of the second rod body 12. The decorative grooves 122 as shown in FIG. 6 do not communicate with the cavity of the second rod body. The arc-shaped decorative grooves 122 are distributed at intervals along the length direction of the second rod body where they are located. Of course, as shown in FIG. 7, the decorative grooves 122 do not communicate with the cavity of the second rod body, and the decorative grooves 122 are distributed at intervals along the circumferential direction of the second rod body.

Furthermore, a first plug 14 for plugging may be mounted via embedded fixation or threaded connection in the cavity of the second rod body in front of the distribution area of the decorative grooves 122, and a second plug 15 for sealing may be mounted arranged in a second cylindrical opening 124 which is behind the distribution area of the decorative grooves 122 and located at the end face of the tail end of the second rod body 12. The second plug 15 is also fixed via embedded fixation or threaded connection for example. The first plug 14 is provided for helping to reduce impurities entering the cavity of the second rod body, and the second plug 15 can improve the aesthetic appearance while playing a sealing role.

Also, second anti-slip convex rings 121 are formed at intervals along a length extension direction at the peripheral wall of the second rod body 12. For example, a second convex ring 121 is formed at the head end of the second rod body; and second convex rings 121 are formed at intervals at the tail end of the second rod body 12 and the area of the decorative grooves 122 is located between two second convex rings 121. The structure of the second convex ring 121 is consistent with the structure of the first convex ring 105. Moreover, a third anti-slip convex ring 112 is formed at the peripheral wall of the tail end of the first rod body 11. The structure of the third convex ring 112 is consistent with the structure of the first convex ring 105.
