Description

Technical Field

[0001] This utility model relates to the technical field of copper hoop fittings, and in particular to a billiard cue explosion-proof and anti-loosening hoop. Background Technology

[0002] Currently, Chinese patent publication number CN211215363U discloses a cue stick, including a cue stick body and a tip connected to the cue stick body. The cue stick body includes an inner core for reinforcement inside the end that strikes the billiard ball, and a tip or brass band around the outside of the end that strikes the billiard ball. After replacing the brass band on the cue stick, it is usually polished and sanded to clean the glue residue. However, after sanding, the outer diameter of the top of the cue stick will be reduced, and the brass band will not fit tightly. Even after being glued, it is still easy to loosen. Summary of the Invention

[0003] Therefore, in response to the above problems, this utility model proposes a billiard cue explosion-proof and anti-loosening hoop, which solves the technical problem that the outer diameter of the top of the cue will shrink after grinding, the copper hoop will not fit tightly, and it will still easily loosen after being glued.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a billiard cue explosion-proof and anti-loosening hoop, comprising a hoop body, a spacer disposed in the middle of the hoop body, and a cue tip detachably disposed on the top of the hoop body. The outer diameter of the hoop body gradually decreases from bottom to top. The top of the hoop body is provided with a cylindrical groove for inserting the cue tip. The middle of the hoop body is provided with a protruding ring for blocking the cue tip. The bottom of the inner side of the hoop body is provided with an inner groove. The hoop body is provided with a stepped hole at the position of the inner groove. The hoop body is provided with an overflow hole at the position of the cylindrical groove.

[0005] Furthermore, a sloping transition section is provided at the bottom half-circle of the stepped hole.

[0006] Furthermore, the hoop is screwed into the stepped hole with a clamping screw, which includes an outer ring cover plate and a threaded protrusion located on one side of the outer ring cover plate. The outer ring cover plate has a cross groove at the middle of the threaded protrusion.

[0007] Furthermore, after the threaded protrusion engages with the stepped hole, the outer ring cover is located in the middle of the stepped hole.

[0008] By adopting the aforementioned technical solution, the beneficial effects of this utility model are:

[0009] This billiard cue features an explosion-proof and anti-loosening clamp. Because the spacer fits into the inner groove and convex ring of the clamp body, when the clamp body is inserted into the billiard cue head, the spacer will hold the billiard cue head tightly inside the clamp body. The bottom part without the spacer is reinforced with a clamping screw, which can prevent the problem of loosening after the billiard cue head is replaced and polished. Attached Figure Description

[0017] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0018] refer to Figures 1 to 7 This embodiment provides a billiard cue explosion-proof and anti-loosening clamp, including a clamp body 100, a spacer 200 disposed in the middle of the clamp body 100, and a cue tip 300 detachably disposed on the top of the clamp body 100. The outer diameter of the clamp body 100 gradually decreases from bottom to top. The top of the clamp body 100 is provided with a cylindrical groove 1 for inserting the cue tip 300. The middle of the clamp body 100 is provided with a protruding ring 2 for blocking the cue tip 300. The bottom of the inner side of the clamp body 100 is provided with an inner groove 3. The clamp body 100 is provided with a stepped hole 4 at the position of the inner groove 3. The clamp body 100 is provided with an overflow hole 5 at the position of the cylindrical groove 1.

[0019] During the production process, spacers of a specific thickness are selected according to the wear degree of the billiard cue head. Since the spacers fit the inner groove surface and the convex ring part inside the hoop, when the hoop is inserted into the billiard cue head, the spacers will hold the billiard cue head tightly inside the hoop. In addition, the excess glue on the outside of the billiard cue head will overflow through the stepped hole, avoiding the problem of loose fit with the copper hoop after the billiard cue head is replaced and polished.

[0020] When installing the cue tip, spacers are installed on batches of hoops on the assembly line. After the spacers are fixed, adhesive is sprayed into the cylindrical groove at the top of the hoop, and adhesive is also sprayed onto the top surface of the spacers. After completion, the cue tip is directly pressed onto the top of the hoop. Since the wall thickness of the hoop at the cylindrical groove position is less than the wall thickness of the inner groove of the hoop, the stressed part of the cue tip will be squeezed into the hoop. Some material is cut to the outside of the hoop by the top of the hoop, and some excess adhesive inside the hoop will be discharged through the overflow hole. Then the hoop is placed in an external grinder to grind the cue tip. This hoop can be mass-produced. When billiard halls need to replace cue tips or brass hoops, the hoop with the cue tip can be directly installed on the cue tip, saving the step of replacing the cue tip for the user. It is suitable for use in scenarios where the cue tip wears out quickly and needs to be replaced frequently. The worn hoops can be collected and recycled. After a batch is collected, the cue tips can be replaced centrally, reducing the time that store staff spend replacing cue tips during peak working hours.

[0021] The bottom half of the stepped hole 4 is provided with a sloping transition section. When installing the hoop, the club head is first coated with glue, and then the hoop is put on the club head. The glue that overflows from the club head overflows through the bottom of the stepped hole. The sloping transition section can prevent the overflow glue from getting stuck on the right angle surface and causing the problem of being difficult to clean.

[0022] The clamp 100 is screwed into the stepped hole 4 with a locking screw. The locking screw includes an outer ring cover plate 601 and a threaded protrusion 602 located on one side of the outer ring cover plate 601. The outer ring cover plate 601 is provided with a cross groove 603 at the middle position of the threaded protrusion 602. After the threaded protrusion is screwed into the stepped hole 4, the outer ring cover plate 601 is located at the middle position of the stepped hole 4.

[0023] The outer ring cover can cover the stepped hole, improving the aesthetics of the hoop. The cross groove is located at the threaded protrusion position to prevent the outer ring cover from deforming under stress during use. After the hoop is inserted into the top of the cue stick, tightening the threaded protrusion will push against the top of the cue stick, further increasing the loosening performance. Since the depth of the threaded protrusion is the same as the other half of the stepped hole depth, it can be adjusted further to increase the clamping performance, and the outer ring cover will not bulge outward, improving the aesthetics.

[0024] The hoop 100 has cutting blades 400 on both sides, and an elastic sheet 401 is fixed on the top of the cutting blade 400. The cutting blade 400 fits against the outer arc surface of the hoop 100. The bottom of the cutting blade 400 has an L-shaped protrusion 402. The outer side of the hoop 100 has a stepped groove 403 for the L-shaped protrusion 402 to be inserted. The cutting blade 404 is provided at the tip 300 position.

[0025] During use, press the cutting blade downwards. The L-shaped protrusion at the bottom of the cutting blade will engage with the stepped groove on the outside of the clamp. Then rotate the top elastic plate. As the elastic plate pulls the cutting blade towards the center, the cutting blade will perform rapid coarse cutting on the tip located on the outside of the clamp during the rotation of the elastic plate. The stepped groove guides the cutting blade to slide. When pressing the cutting blade downwards, the L-shaped protrusion at the bottom of the cutting blade will fit against the bottom of the stepped groove, preventing the cutting blade from accidentally falling into the clamp. This clamp and cutting blade work together more safely and are less likely to cut your hand compared to existing blades.
