Description

Technical Field

[0001] This utility model belongs to the technical field of billiard table accessories, and specifically relates to a billiard table leveling component. Background Technology

[0002] A pool table is an essential piece of equipment for playing billiards. The leveling of the slate on a pool table is very important, as it directly affects the gaming experience and the fairness of the competition.

[0003] Patent CN222384138U discloses a billiard table slate leveling device, including a main support structure, an integrated leveling bolt, and a height adjuster. The lower end of the integrated leveling bolt protrudes downward to form a limiting post. The height adjuster is located between the integrated leveling bolt and the main support structure. The integrated leveling bolt, the height adjuster, and the main support structure are connected sequentially through the limiting post. When leveling the slate, the main support structure is fixedly connected to the main frame of the billiard table, the integrated leveling bolt supports the slate, and the height adjuster makes fine adjustments to the height of the slate through threads. A steel ball is set at the top of the integrated leveling bolt. By adjusting the position of the steel ball, the steel ball contacts the slate when making coarse adjustments to the slate height, and the slate contacts the rubber pad of the integrated leveling bolt when making fine adjustments to the slate height.

[0004] The aforementioned leveling device, when fully supported, allows the rubber pad at the top to contact the stone slab. However, the rubber pad cannot rotate with the stone slab relative to the integrated leveling bolt. When the stone slab is rotated for adjustment, the rubber pad may cause the integrated leveling bolt to rotate together, or the stone slab may rotate directly relative to the rubber pad. This will inevitably affect the smoothness of the stone slab's rotation and may also damage the rubber pad or even scratch the stone slab. Utility Model Content

[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a billiard table leveling component.

[0006] To achieve the innovative objectives of this utility model, the following technical solutions can be used: A billiard table leveling component includes a base, a support rod passing through a connecting hole on the base, a lifting adjustment structure between the base and the support rod, an abutment cap on the top of the support rod, and a rotating component between the abutment cap and the support rod.

[0007] This utility model discloses a billiard table leveling component that can be installed between the lower table body and the slate of a billiard table to support the slate and adjust its height. It mainly consists of a base and a support rod. The base is located on the lower table body, and its flange has screw holes for bolt fixing. The support rod is installed in a vertically penetrating connecting hole in the center of the base. The upper end of the support rod makes contact with the slate through an abutment cap, which is existing technology. The lifting and adjusting structure controls the axial extension and retraction of the support rod relative to the base, thereby supporting the lifting and adjusting of the slate. Furthermore, a rotating component is provided between the top of the support rod and the abutment cap, allowing the abutment cap to rotate freely relative to the support rod. This facilitates rotational adjustment of the slate during installation and avoids sliding friction between the slate and the abutment cap due to relative rotation. In addition, the rotational decoupling of the abutment cap and the support rod ensures that the abutment cap does not rotate with the support rod when the support rod is rotated for lifting and adjusting, thus avoiding friction between the abutment cap and the slate.

[0008] In the above-mentioned billiard table leveling assembly, the abutment cap is cap-shaped and rotatably connected to the top of the support rod, and the rotating assembly is located inside the abutment cap.

[0009] The abutment cap is inserted with its opening facing downwards onto the top of the support rod to ensure radial positioning.

[0010] In the above-mentioned billiard table leveling assembly, the rotating assembly includes a planar bearing, the outer diameter of the steel ring of the planar bearing is adapted to the inner diameter of the abutment cap, and the upper and lower sides of the steel balls of the planar bearing are respectively in rolling contact with the inner top surface of the abutment cap and the upper top surface of the support rod. Alternatively, the rotating assembly may include a plurality of rollers circumferentially distributed on the top surface of the support rod, wherein the axis of the rollers intersects perpendicularly with the axis of the abutment cap, and the inner top surface of the abutment cap rolls in contact with the rollers.

[0011] The rotating assembly can be achieved through a plane bearing. The outer diameter of the steel ring of the plane bearing is adapted to the inner diameter of the abutment cap. The plane bearing and the abutment cap are kept coaxial. The rolling of the steel balls on the plane bearing between the top surface of the support rod and the inner top surface of the abutment cap can support the abutment cap and ensure the smooth rotation of the abutment cap.

[0012] As another feasible solution, the rotating component can also be at least three sets of rollers set on the top surface of the support rod. The rollers roll in cooperation with the inner top surface of the abutment cap to achieve the effect of support and rotation. Of course, the rollers can also be set on the inner top surface of the abutment cap.

[0013] In the above-mentioned billiard table leveling assembly, the support rod includes a rod body and a large head located at the upper end of the rod body, and the large head is rotatably connected to the abutment cap. The lower end of the abutment cap is provided with a radially inward protruding annular stamped part. The outer diameter of the large head is adapted to the inner diameter of the abutment cap, but is larger than the inner diameter of the stamped part. The stamped part is inwardly engaged below the limiting step between the large head and the rod body.

[0014] The support rod consists of an integrally connected rod body and a large head. Both the large head and the rod body are cylindrical, but the outer diameter of the large head is larger than that of the rod body. A limiting step is formed on the outer periphery of the bottom surface of the large head. The stamped part below the abutment cap engages inward with this limiting step, achieving axial limiting of the abutment cap. However, the two parts do not contact each other under normal conditions to avoid affecting the smooth rotation of the abutment cap. This stamping part can be stamped after the abutment cap is installed on the large head. The structure is simple, the processing is not difficult, and it also ensures the stability of the axial limiting.

[0015] In the above-mentioned billiard table leveling assembly, the lifting adjustment structure includes an internal thread provided on the wall of the connecting hole and an external thread provided on the rod body of the support rod, wherein the internal thread and the external thread are engaged.

[0016] The lifting and adjusting mechanism is achieved through a thread, and the lifting and lowering of the support rod is realized by controlling the rotation of the support rod relative to the connecting hole.

[0017] In the above-mentioned billiard table leveling assembly, the upper end of the support rod is provided with a rotating structure for rotating the support rod, and the rotating structure is exposed below the abutment cap.

[0018] The rotating structure is used to control the rotation of the support rod. This rotating structure is exposed below the abutment cap, which ensures smooth operation for the user and reduces the space occupied by the external thread arrangement on the rod.

[0019] In the above-mentioned billiard table leveling assembly, the rotating structure includes a rotating part disposed at the upper end of the cue body, or a rotating lever that extends radially at the upper end of the cue body. The rotating part is non-circular or circular with a rough texture on the outer wall. The non-circular part includes one or more of the following shapes: square, hexagonal, octagonal, and elliptical.

[0020] The rotating structure preferably uses a hexagonal rotating part, which acts as a nut fixed to the rod body. The support rod can be easily rotated using a matching wrench. Of course, the rotating part can also be other non-circular shapes, allowing rotation with appropriate tools. Even a circular shape with rough ribs on the outer wall can be rotated by hand under light loads. Alternatively, the rotating structure can be implemented using a rotating lever on the rod body. This lever can be inserted into the rod body, allowing for easy manual rotation by the user.

[0021] In the above-mentioned billiard table leveling assembly, the cue body is also fitted with an anti-loosening nut, which is located between the base and the abutment cap, and its bottom surface is in close contact with the top surface of the base.

[0022] The anti-loosening nut can be screwed down until it fits tightly against the base after the support rod has been rotated and adjusted, increasing the pressure between the external and internal threads, thereby increasing the force required for the support rod to rotate and preventing the support rod from rotating on its own.

[0023] In the above-mentioned billiard table leveling assembly, the top of the abutment cap is provided with an elastic pad, and the elastic pad and the abutment cap are detachable and fixed.

[0024] The elastic pad is preferably made of rubber and is used to make direct contact with the stone slab to avoid damaging the slab. It can also increase the friction with the stone slab. The detachable design makes it easy to install and remove. Of course, in actual implementation, it is also possible to choose not to install the elastic pad to avoid height instability caused by the elasticity of the elastic pad.

[0025] In the above-mentioned billiard table leveling assembly, the elastic pad has a connecting countersunk hole in the middle, the abutment cap has a connecting screw hole at the center of the top, the connecting countersunk hole has a connecting screw, and the lower end of the connecting screw engages with the connecting screw hole.

[0026] The elastic pad is connected to the abutment cap by a connecting screw. The head of the connecting screw is located inside the connecting countersunk hole to prevent the head from protruding and contacting the stone slab.

[0027] Compared with the prior art, the present invention has the following main advantages: 1. This utility model includes a rotating component between the support rod and the abutment cap, allowing the abutment cap to rotate freely relative to the support rod. This facilitates rotational adjustment of the stone slab during installation and avoids sliding friction between the stone slab and the abutment cap due to relative rotation. Furthermore, the decoupling of the abutment cap from the support rod's rotation ensures that the abutment cap will not rotate with the support rod during height adjustment, thus preventing friction between the abutment cap and the stone slab.

[0028] 2. The rotating assembly is achieved through a plane bearing, which supports the abutment cap and ensures its smooth rotation.

[0029] 3. The stamped part below the abutment cap snaps inward to the lower part of the limiting step to achieve axial limiting of the abutment cap. The stamping part is stamped after the abutment cap is installed on the large head, which ensures the stability of the axial limiting. Attached Figure Description

Detailed Implementation

[0032] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0033] Specific implementation examples Figures 1-5 As shown, the billiard table leveling assembly includes a base 1, a support rod 3 passing through a connecting hole 2 on the base 1, a lifting adjustment structure 4 between the base 1 and the support rod 3, an abutment cap 5 on the top of the support rod 3, and a rotating assembly 6 between the abutment cap 5 and the support rod 3.

[0034] Specifically, the billiard table leveling assembly is located between the lower body of the billiard table and the slate. The lifting and adjusting structure 4 is used to control the axial extension and retraction of the support rod 3 relative to the base 1, thereby supporting the lifting and adjusting of the slate. Moreover, a rotating component 6 is provided between the top of the support rod 3 and the abutment cap 5, allowing the abutment cap 5 to rotate freely relative to the support rod 3. This facilitates the rotation adjustment of the slate during installation and avoids sliding friction between the slate and the abutment cap 5 due to relative rotation. In addition, the rotational decoupling between the abutment cap 5 and the support rod 3 also ensures that the abutment cap 5 will not rotate with the support rod 3 when the support rod 3 is rotated for lifting and adjusting, thus naturally avoiding friction between the abutment cap 5 and the slate.

[0035] like Figure 1 , 2As shown in Figure 3, the support rod 3 includes a rod body 8 and a large head 9 located at the upper end of the rod body 8. The abutment cap 5 is cap-shaped and rotatably connected to the large head 9. The rotating assembly 6 is located inside the abutment cap 5. The rotating assembly 6 includes a plane bearing 7. The outer diameter of the steel ring of the plane bearing 7 is adapted to the inner diameter of the abutment cap 5. The upper and lower sides of the steel balls of the plane bearing 7 are respectively in rolling contact with the inner top surface of the abutment cap 5 and the upper top surface of the support rod 3. The lower end of the abutment cap 5 is provided with a radially inwardly protruding annular stamped part 10. The outer diameter of the large head 9 is adapted to the inner diameter of the abutment cap 5, but larger than the inner diameter of the stamped part 10. The stamped part 10 is inwardly engaged below the limiting step 11 between the large head 9 and the rod body 8.

[0036] Specifically, the abutment cap 5 is fitted onto the top of the support rod 3 with its opening facing downwards, ensuring radial positioning. The outer diameter of the steel ring of the plane bearing 7 is adapted to the inner diameter of the abutment cap 5. The plane bearing 7 and the abutment cap 5 remain coaxial. The rolling of the steel balls on the plane bearing 7 between the top surface of the support rod 3 and the inner top surface of the abutment cap 5 supports the abutment cap 5 and ensures its smooth rotation. The support rod 3 consists of an integrally connected rod body 8 and a large head 9. Both the large head 9 and the rod body 8 are cylindrical, but the outer diameter of the large head 9 is larger than that of the rod body 8. A limiting step 11 is formed on the outer circumference of the bottom of the large head 9. The stamped part 10 below the abutment cap 5 engages inwards below this limiting step 11, achieving axial limiting of the abutment cap 5. However, the two do not contact each other under normal conditions to avoid affecting the smooth rotation of the abutment cap 5. The stamped part 10 can be stamped after the abutment cap 5 is installed on the large head 9, ensuring the stability of the axial limiting.

[0037] like Figure 1 , 2 As shown in Figure 3, the bottom of the base 1 is also provided with an extension tube 20 corresponding to the connecting hole 2. The base 1 is plate-shaped and forms a T-shaped structure with the extension tube 20. The inner wall of the extension tube 20 is smoothly connected to the inner wall of the connecting hole 2. The lifting adjustment structure 4 includes an internal thread provided on the connecting hole 2 and the inner wall of the extension tube, and an external thread provided on the rod body 8 of the support rod 3. The internal thread and the external thread are meshed. The upper end of the support rod 3 is provided with a rotating structure 12 for rotating the support rod 3. The rotating structure 12 is exposed below the abutment cap 5. The rotating structure 12 includes an external hexagonal rotating part 13 provided on the upper end of the rod body 8. A lock nut 15 is also engaged on the rod body 8. The lock nut 15 is located between the base 1 and the abutment cap 5, and its bottom surface is in close contact with the top surface of the base 1.

[0038] Specifically, the lifting and adjusting structure 4 is achieved through a thread. The support rod 3 is raised or lowered by controlling its rotation relative to the connecting hole 2. The extension tube extends the length of the internal thread, increasing the overall support force. The rotating structure 12 is specifically an external hexagonal rotating part 13, which allows for easy rotation of the support rod 3 using a matching wrench. The rotating part 13 protrudes below the abutment cap 5, ensuring smooth operation for the user and reducing the space occupied by the external thread arrangement on the rod body 8. The anti-loosening nut 15 can be screwed down to fit tightly against the base 1 after the support rod 3 has been adjusted, increasing the pressure between the external and internal threads, thereby increasing the force required for the support rod 3 to rotate and preventing the support rod 3 from rotating on its own.

[0039] like Figure 1 , 2 As shown in Figures 4 and 5, the top of the abutment cap 5 is provided with an elastic pad 16, the middle of the elastic pad 16 is provided with a connecting countersunk hole 17, the top center of the abutment cap 5 is provided with a connecting screw hole 18, the connecting countersunk hole 17 is provided with a connecting screw 19, and the lower end of the connecting screw 19 engages with the connecting screw hole 18.

[0040] Specifically, the elastic pad 16 is used to make direct contact with the stone slab to avoid damaging the stone slab, and at the same time it can increase the friction with the stone slab. The elastic pad 16 is connected to the abutment cap 5 by the connecting screw 19. The head of the connecting screw 19 is located in the connecting countersunk hole 17 to prevent the head from protruding and contacting the stone slab.

[0041] Working principle: During installation, the base 1 is placed in the corresponding position on the lower table body and fixed with bolts. The stone slab is placed on the abutment cap 5, contacting the elastic pad 16 at the top of the support rod 3. When rotation adjustment is required, the stone slab can rotate around the corresponding abutment cap 5 as the center. At this time, the abutment cap 5 rotates with the stone slab relative to the support rod 3. When the height needs to be adjusted, the anti-loosening nut 15 is rotated until it contacts the base 1. Then, the rotating part 13 is rotated, and the support rod 3 rotates relative to the base 1. With the cooperation of the external and internal threads, the axial lifting and lowering of the support rod 3 is achieved. The stone slab on the support rod 3 is simultaneously lifted and lowered for adjustment. After adjustment, while keeping the rotating part 13 from rotating, the anti-loosening nut 15 is rotated in the opposite direction until the anti-loosening nut 15 is tightly attached to the base 1. The adjustment is then complete.

Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
