Description

Technical Field

[0001] This utility model belongs to the field of billiard cue technology and relates to a heavy-duty billiard cue. Background Technology

[0002] As is well known, existing billiard cues are shafts that gradually thicken from the front to the back, with the rear end serving as the grip. The weight of each billiard cue produced by the manufacturer is relatively fixed, but the weight of a cue that suits or is preferred by different users varies. To meet practical needs, existing billiard cues have incorporated weight-bearing structures, such as the heavy-duty billiard cue described in Chinese Patent No. "201220609822.6". The specific structure of this heavy-duty billiard cue is as follows: it consists of a rear section, a lower ring, a middle roller, an upper ring, a front section, a tip, a rubber seat, and a rubber base. The outer side of the rear section has a non-slip grip section, and the bottom of the rear section is fixedly fitted with a rubber base. The top surface of the rear section is fixedly fitted with the lower ring, the bottom surface of the middle roller is fixed above the lower ring, the top surface of the middle roller is fixedly connected to the upper ring, the bottom end of the front section is fixed above the upper ring, the top end of the front section is fixedly connected to the tip, and the tip is fixedly fitted to the top of the tip. The lower and upper rings cushion the impact force and prevent the wood from cracking during powerful shots. The middle wheel connects the front and rear sections of the cue. The ferrule is made of metal or plastic. The rubber base adds weight to the entire cue. This structure, relying on the rubber base for weight addition, lacks adjustable weight, limiting its applicability and resulting in a rigid, fixed design. Summary of the Invention

[0003] The purpose of this invention is to address the aforementioned problems in the prior art by providing a weight-adjustable heavy-duty billiard cue.

[0004] The objective of this utility model can be achieved through the following technical solution: a heavy-duty billiard cue, including a cue body, a weight, and a mounting base. The tail of the cue body has a first receiving cavity, the weight is threadedly installed in the first receiving cavity, the mounting base has an external thread, the mounting base is threadedly installed at the opening end of the first receiving cavity, the end face of the mounting base is in close contact with the end face of the weight, and an internal threaded hole is also formed through the mounting base.

[0005] The aforementioned heavy-duty billiard cue also includes a back plug, the part of which can be threaded into the internal threaded hole.

[0006] The aforementioned heavy-duty billiard cue also includes an extended handle, the end of which is provided with an insertion rod. The insertion rod has an external thread so that it can be threaded into the internal threaded hole.

[0007] In the aforementioned heavy-duty billiard cue, the weight is made of metal.

[0008] Compared with existing technologies, this heavy-duty billiard cue features a threaded installation that allows for detachable connections between the weight and the cue body, as well as between the mounting base and the cue body. When the weight needs to be replaced, the mounting base is rotated to remove it, and then the weight is rotated to remove it, allowing for the replacement of weights of different weights. This enables rapid weight adjustment and has a wide range of applications. The mounting base has an internal threaded hole, which allows for the threaded installation of a back plug and extension handle. Installation and removal are simple and convenient, facilitating the switching between the back plug and extension handle, and enabling flexible adjustment of the billiard cue length. This also makes it widely applicable. Attached Figure Description

[0012] In the figure, 1 is the rod body; 11 is the first receiving cavity; 2 is the weight block; 3 is the mounting base; 31 is the internal threaded hole; 4 is the rear plug; 5 is the extension handle; and 51 is the insertion rod. Detailed Implementation

[0013] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0014] like Figure 1-3 As shown, this heavy-duty billiard cue includes a cue body 1, a weight block 2, and a mounting base 3. The tail of the cue body 1 has a first receiving cavity 11, and the weight block 2 is threadedly installed within the first receiving cavity 11. The mounting base 3 has external threads and is threadedly installed at the open end of the first receiving cavity 11. The end face of the mounting base 3 is in close contact with the end face of the weight block 2, thus reinforcing the installation of the weight block 2. The threaded installation allows for a detachable connection between the weight block 2 and the cue body 1, and between the mounting base 3 and the cue body 1, facilitating the replacement of weight blocks 2 with different weights. The weight block 2 is made of metal and comes in several different weights, such as 5g, 10g, 14g, 21g, and 35g, allowing different users to easily change to different weights, enabling rapid weight adjustment and broad applicability.

[0015] In the above technical solution: the mounting base 3 also has an internal threaded hole 31.

[0016] The above technical solution also includes a rear plug 4, the rod of which can be threaded into the internal threaded hole 31.

[0017] The above technical solution also includes an extended handle 5, the end of which is provided with an insertion rod 51. The insertion rod 51 has external threads, allowing it to be threaded into the internal threaded hole 31. When the extended handle 5 is not needed, the rear plug 4 is threaded onto the mounting base 3. When the extended handle 5 is needed, the rear plug 4 is rotated to remove it from the mounting base 3, and then the insertion rod 51 of the extended handle 5 is threaded onto the mounting base 3. The disassembly and installation process is simple and quick, making it easy to replace the rear plug 4 with the extended handle 5, thus achieving flexible adjustment of the billiard cue length and making it widely applicable.

[0018] This heavy-duty billiard cue features a threaded connection between the weight block 2 and the cue body 1, and between the mounting base 3 and the cue body 1. To replace the weight block 2, simply rotate and remove the mounting base 3, then rotate and remove the weight block 2. This allows for the replacement of weight blocks 2 of different weights, enabling rapid weight adjustment and broad applicability. The mounting base 3 has an internal threaded hole 31, allowing for the threaded installation of a rear plug and extension handle. Installation and removal are simple and convenient, facilitating switching between the rear plug and extension handle, and enabling flexible adjustment of the billiard cue length, further enhancing its applicability.
