Split-type assembled billiard cue

Abstract

A split-type assembled billiard cue including a cue rear section. The cue rear section includes a first rod body, a second rod body, a connecting pin for fixation with a cue front section, and a counterweight. In this solution, the first rod body and the second rod body, in combination with the connecting pin, form the cue rear section. The counterweight is placed in a placement cavity of the first rod body. The first rod body or the first rod body, when damaged, can be replaced separately, thereby reducing the subsequent maintenance cost.

What is claimed is:

A split-type assembled billiard cue, comprising a cue rear section, wherein the cue rear section comprises a first rod body, a second rod body, a connecting pin for fixation with a cue front section, and a counterweight; the connecting pin is fixed at a head end of the first rod body, and a tail end of the first rod body is fixed with a head end of the second rod body; the first rod body is provided therein with a placement cavity extending along a length direction of the first rod body; and the counterweight is arranged in the placement cavity. 
     
     
         2 . The split-type assembled billiard cue according to  claim 1 , wherein the placement cavity extends to an end face of the tail end of the first rod body; a protrusion for limiting a position is provided at a wall of the placement cavity adjacent to the tail end; a mounting opening communicating with the placement cavity is formed at an end face of the head end of the first rod body; the mounting opening is configured for the counterweight to be inserted into the placement cavity; a tail end of the connecting pin is fixed in the mounting opening; and the tail end of the connecting pin cooperates with the protrusion to clamp the counterweight in the placement cavity. 
     
     
         3 . The split-type assembled billiard cue according to  claim 1 , wherein the second rod body is cylindrical, and the tail end of the first rod body is fixed in a first cylindrical opening at the head end of the second rod body. 
     
     
         4 . The split-type assembled billiard cue according to  claim 1 , wherein decorative holes communicating with the placement cavity are formed at intervals at a peripheral wall of the first rod body. 
     
     
         5 . The split-type assembled billiard cue according to  claim 1 , wherein ribs are formed at intervals on a peripheral wall of the counterweight along a length direction of the counterweight. 
     
     
         6 . The split-type assembled billiard cue according to  claim 1 , wherein the second rod body is cylindrical, and decorative grooves are distributed at intervals at a peripheral wall of a tail end of the second rod body. 
     
     
         7 . The split-type assembled billiard cue according to  claim 6 , wherein a first plug for plugging is arranged in a cavity of the second rod body in front of a distribution area of the decorative grooves, and a second plug for sealing is arranged in a second cylindrical opening which is behind the distribution area of the decorative grooves and located at an end face of the tail end of the second rod body. 
     
     
         8 . The split-type assembled billiard cue according to  claim 1 , wherein the connecting pin comprises a main body, a threaded stud at a head end of the main body, and an insertion post at a tail end of the main body; the threaded stud is configured for threaded connection with the cue front section; and the insertion post is connected with the head end of the first rod body. 
     
     
         9 . The split-type assembled billiard cue according to  claim 8 , wherein a decorative pattern is provided at a peripheral wall of the main body, and a first anti-slip convex ring is provided at the peripheral wall of the main body behind an area where the pattern is located. 
     
     
         10 . The split-type assembled billiard cue according to  claim 1 , wherein second anti-slip convex rings are arranged at intervals at a peripheral wall of the second rod body along a length extension direction of the second rod body; and a third anti-slip convex ring is arranged at a peripheral wall of the tail end of the first rod body.
