Description

Technical Field

[0001] This utility model relates to the field of billiard cue technology, and in particular to a cue handle structure. Background Technology

[0002] The buttstock of a billiard cue is the core component for grip and weight distribution. It is typically made of hardwood or composite materials and achieves a balance between aesthetics and function through precision machining and inlay work. Its design employs a segmented structure, including the connecting thread and grip. High-end buttstocks incorporate carbon fiber stabilizers or metal decorative rings to enhance torsional rigidity. The surface finish is either piano lacquer or a matte UV coating, providing both moisture resistance and a smooth feel.

[0003] Most existing billiard cue butts are made of wood or semi-wood. Wood contains moisture. If the billiard cue is stored in an unsuitable environment or is not properly maintained, the moisture in the wood will be lost. This will not only reduce the weight of the billiard cue, but also cause the butt to crack, bend and deform. This will affect the feel and accuracy of the billiard cue, and in severe cases, it will render the billiard cue unusable. Therefore, we propose a new butt structure for billiard cues. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a new cue handle structure.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a cue handle structure, comprising an outer carrier and a sealed inner ring, wherein the sealed inner ring is fixedly connected to the upper end face of the outer carrier, and further comprising:

[0006] The ash wood stick is fixedly connected to the outer carrier, and the upper end face of the ash wood stick is closely attached to the lower end face of the sealing middle ring. The ash wood stick is fixedly connected with a connector, and the upper end face of the connector penetrates through the sealing middle ring. The lower end face of the ash wood stick is chiseled with a first slot, and the upper inner wall of the first slot is chiseled with a first circular groove.

[0007] A maple stick is fixedly connected to the outer carrier. The upper part of the maple stick is inserted into the first slot. A metal connecting rod is fixedly connected inside the maple stick. The upper part of the metal connecting rod is fixedly connected into the first circular groove. A second slot is carved on the lower end face of the maple stick.

[0008] The first bakelite sheet is fitted onto the upper part of the maple stick and is located between the maple stick and the ash stick.

[0009] A sealing rod, wherein the sealing rod is fixedly connected to the outer carrier and the upper part of the sealing rod is inserted into the second slot;

[0010] The second bakelite piece is fitted onto the upper part of the sealing rod and is located between the maple rod and the sealing rod.

[0011] Preferably, the growth rings of the ash wood stick and the maple wood stick are arranged at a 90-degree angle.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] This solution replaces the traditional tubular core with a sealing core with a sealing head, thus sealing the upper part of the outer carrier. This helps prevent the ash wood stick from directly contacting the air and causing moisture loss. By placing a first bakelite sheet between the ash and maple sticks, moisture exchange between the two sticks is prevented from causing moisture loss within the wood. By placing a second bakelite sheet between the maple stick and the sealing rod, the lower side of the maple stick is sealed, further preventing the wood within the entire shaft from directly contacting the air and causing moisture loss. This helps prevent wood cracking and deformation that could affect the shaft's performance, thereby improving the accuracy of the shaft during use, reducing shot deviation, increasing bending resistance, and suppressing cracking caused by moisture loss.

[0014] This device, by placing ash and maple sticks at a 90-degree angle where their annual rings intersect, can increase the strength of the club during impact, making the club less prone to deformation and vibration. This, in turn, helps reduce shot deviation and improves the feel and accuracy of the shot. Maple has good elasticity, while ash has high hardness, providing a localized hardening effect. The cross-shaped arrangement of the wood grain refers to the texture of the internal and external structures, and its function is to suppress unidirectional natural bending by artificially intervening in the direction of the wood grain.

[0019] The following description is intended to disclose the present invention so that those skilled in the art can implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0020] like Figures 1-3 The illustrated club handle structure includes an outer carrier 1 and a sealed inner ring 2, the sealed inner ring 2 being fixedly connected to the upper end face of the outer carrier 1, and further includes:

[0021] Ash wood rod 3 is fixedly connected to the outer carrier 1, and the upper end face of ash wood rod 3 is closely attached to the lower end face of the sealing middle ring 2. A connector 4 is fixedly connected inside ash wood rod 3, and the upper end face of connector 4 penetrates through the sealing middle ring 2. A first slot 6 is carved on the lower end face of ash wood rod 3, and a first circular groove 5 is carved on the upper inner wall of the first slot 6.

[0022] Maple stick 7 is fixedly connected to the outer carrier 1. The upper part of the maple stick 7 is inserted into the first slot 6. A metal connecting rod 8 is fixedly connected inside the maple stick 7. The upper part of the metal connecting rod 8 is fixedly connected to the first circular groove 5. A second slot 10 is carved on the lower end face of the maple stick 7.

[0023] The first bakelite sheet 9 is fitted onto the upper part of the maple stick 7, and the first bakelite sheet 9 is located between the maple stick 7 and the ash stick 3.

[0024] The sealing rod 12 is fixedly connected to the outer carrier 1, and the upper part of the sealing rod 12 is inserted into the second slot 10.

[0025] The second bakelite piece 11 is sleeved on the upper part of the sealing rod 12, and the second bakelite piece 11 is located between the maple rod 7 and the sealing rod 12.

[0026] In operation, this solution uses a sealing core 2 with a sealing head to replace the traditional tubular core, thereby sealing the upper part of the outer carrier 1. This helps to prevent the ash wood stick 3 from directly contacting the air and causing moisture loss. By placing a first bakelite sheet 9 between the ash wood stick 3 and the maple stick 7, it helps to prevent moisture exchange between the ash wood stick 3 and the maple stick 7 and causing moisture loss in the wood. By placing a second bakelite sheet 11 between the maple stick 7 and the sealing rod 12, the lower side of the maple stick 7 is sealed. This helps to prevent the wood in the entire shaft from directly contacting the air and causing moisture loss. This helps to prevent the wood from cracking and deforming, affecting the use of the shaft. This helps to improve the accuracy of the shaft during use, reduce the amount of ball offset, increase the bending resistance, and inhibit cracking caused by moisture loss.

[0027] It is worth mentioning that the joints of the splint 4 and the ash wood stick 3, the joints of the ash wood stick 3 and the metal connecting rod 8, the joints of the metal connecting rod 8 and the maple wood stick 7, and the joints of the maple wood stick 7 and the sealing rod 12 are all coated with adhesive. On the one hand, this can facilitate the stability of the joints, and on the other hand, the adhesive can prevent the loss of moisture.

[0028] The sealing rod 12 is made of bakelite material, which helps to prevent moisture loss and improve the sealing effect.

[0029] Specifically, the growth rings of the ash wood stick 3 and the maple wood stick 7 are set at a 90-degree angle to each other.

[0030] During operation, due to the presence of annual rings and wood grain on the wood, practical testing revealed that pressing the shaft parallel to the annual ring grain direction makes it less prone to deformation, while pressing it perpendicular to the annual ring grain direction makes it more prone to deformation. Therefore, this device, by placing ash wood stick 3 and maple wood stick 7 at a 90-degree angle to each other along their annual ring grain direction, can increase the strength of the shaft upon impact, making it less prone to deformation and vibration. This, in turn, helps reduce the amount of deviation during the shot, improving the feel and accuracy of the shot. Maple wood has good elasticity, while ash wood has high hardness, providing a localized hardening effect. The cross-shaped arrangement of the wood grain refers to the texture of the internal and external structures, and its function is to suppress unidirectional natural bending by artificially intervening in the direction of the wood grain.

[0031] Working principle of this utility model:

[0032] In this solution, a sealing middle ring 2 with a sealing head is used instead of a traditional tubular middle ring to seal the upper part of the outer carrier 1, thereby preventing the ash wood stick 3 from directly contacting the air and causing moisture loss. A first bakelite sheet 9 is placed between the ash wood stick 3 and the maple wood stick 7 to prevent moisture exchange between the ash wood stick 3 and the maple wood stick 7 from causing moisture loss in the wood. A second bakelite sheet 11 is placed between the maple wood stick 7 and the sealing rod 12 to seal the lower side of the maple wood stick 7.

[0033] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope. All such changes and modifications fall within the scope of protection claimed by this utility model, which is defined by the appended claims and their equivalents.
