Description

Technical Field

[0001] This invention relates to the field of billiard cue technology, and in particular to a carbon fiber forelimb, carbon fiber buttstock, and carbon fiber billiard cue with an embedded shape memory titanium alloy. Background Technology

[0002] Billiards has become a popular recreational sport, and the billiard cue is a crucial piece of equipment in the game. Choosing a good cue significantly impacts a player's performance and the outcome of a match. Currently, commonly used wooden billiard cues are susceptible to deformation or cracking due to environmental factors and are difficult to preserve, while metal cues are heavy and prone to fatigue with prolonged use. Existing patents, such as Chinese patent application number 202511046756.4, disclose a hybrid fiber composite billiard cue comprising a front support and a rear handle. The front support includes a first core and a first fiber layer and a first reinforcing layer sequentially stacked on the outer periphery of the first core. The rear handle is detachably connected to the front support and includes a second core and a second fiber layer, a second reinforcing layer, and a protective layer sequentially stacked on the outer periphery of the second core. Both the first and second reinforcing layers comprise a three-dimensional woven structure composed of multiple fibers. This patent document describes how the first and second reinforcing layers are designed as a three-dimensional woven structure composed of multiple fibers, which, in conjunction with the protective layer, the first fiber layer, and the second fiber layer, ensures lightweight and corrosion resistance while also enhancing the mechanical properties of the front support and rear handlebars in multiple directions, thus improving service life and user experience. However, it has limited resistance to deformation and bending, and once subjected to significant deformation and bending, it cannot restore its original straightness.

[0003] Therefore, the defects are very obvious, and a solution is urgently needed. Summary of the Invention

[0004] In order to solve the above-mentioned technical problems, the purpose of this invention is to provide a carbon fiber forelimb, a carbon fiber butt handle, and a carbon fiber billiard cue with an embedded memory titanium alloy.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A carbon fiber forelimb with embedded shape memory titanium alloy includes a tip, a prong, a forelimb body, and a central wheel. The diameter of the forelimb body gradually increases from the front end to the rear end. The prong is mounted at the front end of the forelimb body, the central wheel is mounted at the rear end of the forelimb body, and the tip is mounted on the end face of the prong away from the forelimb body. The forelimb body includes a hollow carbon fiber tube and multiple shape memory titanium alloy rods embedded in the carbon fiber tube in a ring array.

[0006] Furthermore, the cross-sectional shape of the shape memory titanium alloy rod is either circular or non-circular.

[0007] Furthermore, the carbon fiber tube has an insert hole inside, into which the shape memory titanium alloy rod is inserted.

[0008] The present invention also provides a carbon fiber rear handlebar with embedded memory titanium alloy, including a large wheel, a rear handlebar body and a rear wheel. The diameter of the rear handlebar body gradually increases from the front end to the rear end. The large wheel is installed at the front end of the rear handlebar body. A threaded stud is provided on the end face of the large wheel away from the rear handlebar body. The rear wheel is installed at the rear end of the rear handlebar body. The rear handlebar body includes a hollow carbon fiber tube and multiple memory titanium alloy rods embedded in the carbon fiber tube in a ring array.

[0009] Furthermore, the cross-sectional shape of the shape memory titanium alloy rod is either circular or non-circular.

[0010] Furthermore, the carbon fiber tube has an insert hole inside, into which the shape memory titanium alloy rod is inserted.

[0011] The present invention also provides a carbon fiber billiard cue with embedded memory titanium alloy, including the aforementioned carbon fiber forelimb.

[0012] Furthermore, the carbon fiber billiard cue also includes a butt handle mounted at the rear end of the carbon fiber forelimb.

[0013] Furthermore, the rear handlebar includes a large wheel, a rear handlebar body, and a rear wheel. The diameter of the rear handlebar body gradually increases from the front end to the rear end. The large wheel is installed at the front end of the rear handlebar body, and a threaded stud is provided on the end face of the large wheel away from the rear handlebar body. The rear wheel is installed at the rear end of the rear handlebar body. The rear handlebar body includes a hollow carbon fiber tube and multiple memory titanium alloy rods embedded in the carbon fiber tube in a ring array. The threaded stud is threaded to the rear end of the carbon fiber front member.

[0014] The present invention also provides a carbon fiber billiard cue with embedded memory titanium alloy, including the carbon fiber butt handle described above.

[0015] The beneficial effects of this invention are as follows: By combining carbon fiber tubes and shape memory titanium alloy rods, this application enables the carbon fiber billiard cue to have high hardness, high elasticity, and high resistance to deformation. It can withstand large deformation and bending and restore its original straightness, providing the billiard cue with more stable and reliable performance. During the use of the billiard cue, it is more wear-resistant, corrosion-resistant, and has a longer service life. In addition, the hollow carbon fiber tube further reduces the weight of the carbon fiber front limb. Attached Figure Description

[0020] like Figures 1 to 3 As shown, the present invention provides a carbon fiber forelimb with embedded shape memory titanium alloy, which includes a skin head 1, a tip angle 2, a forelimb body 3 and a middle wheel 4. The diameter of the forelimb body 3 gradually increases from the front end to the rear end. The tip angle 2 is installed at the front end of the forelimb body 3, the middle wheel 4 is installed at the rear end of the forelimb body 3, and the skin head 1 is installed at the end face of the tip angle 2 away from the forelimb body 3.

[0021] In this embodiment, the cross-sectional shape of the memory titanium alloy rod 6 is circular or non-circular (e.g., elliptical, regular polygon, or irregular polygon).

[0022] In this embodiment, the carbon fiber tube 5 has an insertion hole 7 inside, and the shape memory titanium alloy rod 6 is inserted into the insertion hole 7. This structural design facilitates the precise and stable insertion of the shape memory titanium alloy rod 6 into the carbon fiber tube 5.

It can withstand large deformation and bending and restore its original straightness, providing the billiard cue with more stable and reliable performance. During the use of the billiard cue, it is more wear-resistant, corrosion-resistant, and has a longer service life. In addition, the hollow carbon fiber tube 5 further reduces the weight of the carbon fiber forelimb.

[0024] The present invention also provides a carbon fiber handlebar with embedded memory titanium alloy, including a large wheel 8, a handlebar body 9 and a rear wheel 10.

[0026] In this embodiment, the carbon fiber tube 5 has an insertion hole 7 inside, and the shape memory titanium alloy rod 6 is inserted into the insertion hole 7. This structural design facilitates the precise and stable insertion of the shape memory titanium alloy rod 6 into the carbon fiber tube 5.

[0027] This carbon fiber buttstock combines a carbon fiber tube 5 with a shape memory titanium alloy shaft 6, giving it high hardness, high elasticity, and high resistance to deformation. It can withstand large deformation and bending and restore its original straightness, providing the billiard cue with more stable and reliable performance. During the use of the billiard cue, it is more wear-resistant, corrosion-resistant, and has a longer service life. In addition, the hollow carbon fiber tube 5 further reduces the weight of the carbon fiber forelimb.

[0028] The present invention also provides a carbon fiber billiard cue with embedded memory titanium alloy, including the aforementioned carbon fiber forelimb.

[0029] In this embodiment, the carbon fiber billiard cue also includes a rear handle mounted at the rear end of the carbon fiber forelimb.

During use, the cue is more wear-resistant, corrosion-resistant, and has a longer service life. Furthermore, the hollow carbon fiber tube 5 further reduces the weight of the carbon fiber front leg.
