Description

Technical Field

[0001] The utility model belongs to the technical field of billiard cues and relates to a front rod structure of a billiard cue. Background Art

[0002] As is known to all, the existing billiard cue is a wooden rod body that gradually becomes thicker from the front end to the rear end, and the rear end is the grip end. The billiard cue has high requirements for elasticity. If the common wooden billiard cues on the market need to achieve a certain elastic force, they must use expensive chemical reagents and complex processing technology, or use very scarce wood to solve the problem, which is costly. In response to this situation, a billiard cue has appeared on the market, such as the billiard cue described in Chinese Patent No.: "201520198185.1". The specific structure of the billiard cue is: including a rod body, which includes: a rear section rod; a front section rod, the front end of which has a rod head for mounting a leather head; a guide sleeve, one end of which is connected to the rear section rod, and the front section rod can be slidably inserted in the guide sleeve; and an elastic element, which is arranged in the guide sleeve, and the elastic element is used to provide a forward impulse to the front section rod.

[0003] In the above structure, an elastic element is provided inside the rod to achieve a better elastic effect. However, the structure is complicated and needs to be assembled before use, which is very troublesome. Moreover, as a wearing part, the elastic effect of the elastic element is liable to deteriorate with prolonged use. At the same time, the connection between the tail of the front section rod and the rear section rod made of wood material is thinner due to the opening of the connection hole, and is very prone to breakage. Summary of the invention

[0004] The utility model aims to solve the above problems in the prior art and provides a front rod structure of a billiard cue which can enhance the elasticity of the front rod body and the hardness of the tail of the front rod body.

[0016] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0017] like Figure 1-3As shown, the front rod structure of the billiard cue comprises a front rod body 1, and a cavity 11 is formed at the end of the front rod body 1. The cavity 11 enhances the elasticity of the front rod body 1, reduces the offset of the cue when plugging, ensures the accuracy and flexibility of hitting the ball, avoids the use of scarce wood, and has a simple structure and does not require additional assembly. The cavity 11 can be directly formed integrally on the front rod body 1.

[0018] In the above technical solution: the tail of the front rod body 1 and the rear rod are threadedly connected by screw threads 6. A carbon fiber tube 2 is provided at the tail of the front rod body 1. The carbon fiber tube 2 has the advantages of high strength, long service life, corrosion resistance, wear resistance, etc., and has a long service life. The carbon fiber tube increases the hardness, support and stability of the tail of the front rod body 1, and greatly reduces the breakage of the tail of the front rod body 1.

[0019] In the above technical solution: a front angle 4 is installed at the end of the front rod body 1, an insertion groove is formed on the front angle 4, and a protruding insertion block 16 is formed at the end of the front rod body 1, and the insertion block 16 is inserted into the insertion groove to complete the installation between the front angle 4 and the front rod body 1. The cavity 11 extends to the insertion block 16. A leather head 5 is provided at the end of the front angle 4.

[0020] First embodiment:

The screw thread 6 is located at the tail of the front rod body 1, and the part of the front rod body 1 that matches the screw thread 6 is sleeved with the carbon fiber tube 2.

[0022] Second embodiment:

[0023] An insertion hole is formed in the front rod body 1, and the insertion hole includes a large hole 13 and a small hole 14, and a mounting step 15 is formed between the large hole 13 and the small hole 14. A wooden pin 3 is also included, and the carbon fiber tube 2 is sleeved on the wooden pin 3. The wooden pin 3 is inserted into the insertion hole, and the end of the wooden pin 3 is located in the small hole 14 and fixed to the front rod body 1. The carbon fiber tube 2 is in close contact with the hole wall of the large hole 13, and the end of the carbon fiber tube 2 is in contact with the mounting step 15. The carbon fiber tube 2 is located in the large hole 13 and is not exposed to the outside of the front rod body 1, so as to maintain the consistency of the appearance of the outer surface of the front rod body 1 and prevent the carbon fiber tube 2 from falling. The screw thread 6 is located at the end of the wooden pin 3, and the part of the wooden pin 3 that matches the screw thread 6 is sleeved with the carbon fiber tube 2.
