Description

Technical Field

[0001] This utility model relates to the technical field of sports equipment, specifically a clamping device for pressing the tip of a billiard cue. Background Technology

[0002] Billiard cues are primarily made of ash and Canadian maple, and come in single-piece, two-section, or 3 / 4-section configurations. The butt is often fitted with mahogany or ebony to adjust the weight, while the tip is made of moderately elastic wood to ensure striking power. The standard billiard cue is 1.4-1.5 meters (approximately 91 centimeters) long and weighs between 450-500 grams. The tip is coated with chalk to enhance friction with the ball, prevent slippage, and ensure accuracy and control. Pressing the tip increases the fiber density, making it harder and reducing the contact time with the ball during impact, thus improving accuracy.

[0003] However, existing clamping devices for cue tip pressing are generally unable to flexibly adapt to billiard cues of different diameters. Furthermore, since the diameter of a single cue is not uniform, clamping can easily become loose or excessively tight, damaging the cue tip and causing inconvenience. Therefore, we have provided a cue tip pressing clamping device to solve these problems. Utility Model Content

[0004] (a) Technical problems to be solved This invention proposes a clamping device for pressing the tip of a billiard cue. Through the cooperation between the cue body, spring, and fixing plate, the sleeve moves from the end with the smaller diameter to the end with the larger diameter. As the diameter of the cue body increases, the fixing plate will contact the outer surface of the cue body, and the spring will be compressed. The closer to the end with the larger diameter, the tighter the fixation. This solves the problem that existing clamping devices for pressing are basically unable to flexibly adapt to billiard cues of different diameters. Moreover, since the diameter of a billiard cue is not the same, when pressing the tip, it is easy to cause the clamp to loosen or be too tight, damaging the billiard cue and making the operation inconvenient.

[0005] (II) Technical Solution To achieve the above objectives, this utility model provides the following technical solution: a clamping device for pressing the tip of a billiard cue, comprising a cue body, a tip fixedly connected to one end of the cue body, a sleeve provided on the outer surface of the cue body, a sliding rod slidably connected inside the sleeve, a fixing plate fixedly connected to one end of the sliding rod, the outer surface of the fixing plate slidably connected to the outer surface of the cue body, a spring sleeved on the outside of the sliding rod, one end of the spring fixedly connected to the outer surface of the fixing plate, and the other end of the spring fixedly connected to the inner wall of the sleeve; The outer surface of the sleeve is threadedly connected to an adjusting cylinder, one end of which is fixedly connected to a threaded cylinder, and the inner wall of the threaded cylinder is threadedly connected to a threaded rod.

[0006] Furthermore, a pressure plate is fixedly connected to one end of the threaded rod, and a contact plate is rotatably connected to the outer surface of the pressure plate. The outer surface of the contact plate is slidably connected to the outer surface of the rubber head.

[0007] Furthermore, the outer surface of the fixing plate is fixedly connected with uniformly distributed rubber strips, and the outer surface of the rubber strips is slidably connected to the outer surface of the cue stick body.

[0008] Furthermore, a rotating plate is fixedly connected to one end of the threaded rod, and a cross rod is fixedly connected to the outer surface of the rotating plate.

[0009] Furthermore, the pressure plate has a sliding groove inside, and the inner wall of the sliding groove is slidably connected to the outer surface of the contact plate.

[0010] Furthermore, the outer surface of the sleeve is provided with a threaded groove, and the inner wall of the threaded groove is threadedly connected to the outer surface of the adjusting cylinder.

[0011] Furthermore, an anti-slip plate is fixedly connected to the outer surface of the contact plate, and the outer surface of the anti-slip plate is slidably connected to the outer surface of the rubber head.

[0012] Furthermore, the six fixing plates are arranged in a group and are symmetrically distributed. The device has a total of three groups of fixing plates.

[0013] (III) Beneficial Effects: Compared with existing technologies, this cue tip clamping device has the following advantages: I. This cue tip pressing clamping device, through the cooperation between the cue body, slide rod, spring and fixing plate, when using the device, the sleeve is placed on the outer surface of the cue body, and the sleeve is moved from the end with the smaller diameter to the end with the larger diameter.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] This utility model provides a technical solution: a clamping device for pressing the tip of a billiard cue. Example

[0020] like Figure 1-6As shown, the cue includes a cue body 1, with a cue tip 2 fixedly connected to one end of the cue body 1. A sleeve 3 is provided on the outer surface of the cue body 1. The sleeve 3 is made of 304 stainless steel, which has high strength and resistance to deformation. The surface is nickel-plated to enhance wear resistance. A slide rod 4 is slidably connected inside the sleeve 3. A fixing plate 5 is fixedly connected to one end of the slide rod 4.

[0021] The outer surface of the fixing plate 5 is fixedly connected with uniformly distributed rubber strips 12. The outer surface of the rubber strips 12 is slidably connected to the outer surface of the cue body 1. The rubber strips 12 have a certain degree of flexibility, which will not damage the outer surface of the cue body 1, and can increase the friction between the cue body 1 and the cue body 1, making it easier to fix the sleeve 3. Six fixing plates 5 are arranged in a group and are symmetrically distributed. This device has three groups of fixing plates 5. Each group of six fixing plates 5 forms a multi-point flexible contact with the cue body 1 through the rubber strips 12, avoiding local stress concentration.

[0022] The outer surface of the fixed plate 5 is slidably connected to the outer surface of the cue body 1. A spring 6 is sleeved on the outside of the slide bar 4. The spring 6 is made of high elasticity alloy steel and is quenched and tempered to ensure the springback rate after repeated compression. One end of the spring 6 is fixedly connected to the outer surface of the fixed plate 5. Each slide bar 4 is sleeved with a spring 6. The slide bar 4 can prevent the spring 6 from fatigue bending after repeated use. The other end of the spring 6 is fixedly connected to the inner wall of the sleeve 3. Example

[0023] The outer surface of the sleeve 3 is threaded with an adjusting cylinder 7. One end of the adjusting cylinder 7 is fixedly connected to a threaded cylinder 8. The inner wall of the threaded cylinder 8 is threaded with a threaded rod 9. One end of the threaded rod 9 is fixedly connected to a rotating plate 13. The outer surface of the rotating plate 13 is fixedly connected to a cross rod 14. The cross rod 14 is designed to facilitate the rotation of the rotating plate 13, thereby facilitating the rotation of the threaded rod 9.

[0024] The outer surface of the sleeve 3 is provided with a threaded groove 16. The inner wall of the threaded groove 16 is threadedly connected to the outer surface of the adjusting cylinder 7. When the adjusting cylinder 7 is rotated, it will rotate and move along the inner wall of the threaded groove 16. Since the fixed position of the ball rod body 1 of different diameters is different, the distance between one end of the threaded rod 9 and the tip 2 can be determined by rotating the adjusting cylinder 7. This allows the contact plate 11 at one end of the threaded rod 9 to press the tip 2 when it rotates. When in use, one hand should be held at the connection between the sleeve 3 and the adjusting cylinder 7 to prevent relative rotation between the sleeve 3 and the adjusting cylinder 7 when the threaded rod 9 is rotated. After pressing the tip 2, it can be released normally to press the tip 2 for a certain period of time. Example

[0025] One end of the threaded rod 9 is fixedly connected to a pressure plate 10. The outer surface of the pressure plate 10 is rotatably connected to a contact plate 11. The outer surface of the contact plate 11 is fixedly connected to an anti-slip plate 17. The outer surface of the anti-slip plate 17 is slidably connected to the outer surface of the rubber head 2. The anti-slip plate 17 is made of fluororubber anti-slip layer, which ensures friction and avoids damage to the surface of the rubber head 2.

[0026] The outer surface of the contact plate 11 is slidably connected to the outer surface of the head 2. The inside of the pressure plate 10 is provided with a groove 15. The inner wall of the groove 15 is slidably connected to the outer surface of the contact plate 11. When the threaded rod 9 drives the pressure plate 10 to rotate, the threaded rod 9 gradually moves down, causing the anti-slip plate 17 on the bottom surface of the contact plate 11 to contact the head 2. When the anti-slip plate 17 contacts the head 2 and slightly squeezes the head 2, the friction between the anti-slip plate 17 and the head 2 increases. When the threaded rod 9 continues to rotate, the contact plate 11 will slide on the inner wall of the groove 15, avoiding damage to the head 2 from repeated friction.

[0027] Working principle: In use, sleeve 3 is placed on the outer surface of cue body 1. Sleeve 3 is moved from the end with the smaller diameter of cue body 1 to the end with the larger diameter. As the diameter of cue body 1 increases, the fixing plate 5 will contact the outer surface of cue body 1 and compress it. At this time, spring 6 is compressed and slide rod 4 moves outward. The closer to the end with the larger diameter, the tighter the fixation. This method can be used for cue bodies 1 of different diameters. After sleeve 3 is installed, rotating adjusting cylinder 7 can adjust the distance between threaded rod 9 and tip 2. After adjusting the distance, rotating threaded rod 9 again causes it to rotate inside threaded cylinder 8, which drives pressure plate 10 to move downward. Pressure plate 10 drives contact plate 11 to compress tip 2.

[0028] 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 illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
