Technical Field

[0001] The present application relates to the technical field of sports equipment, and in particular to a device for continuously applying pressure to the tip of a billiard cue stick. Background Art

[0002] In the prior art, it is usually difficult for the pressing device to maintain a constant pressing force during the bonding process between the billiard cue and the leather head, resulting in unstable pressing, which affects the bonding effect and service life.

[0003] In addition, the clamping surface design of the existing clamp is mostly a fixed arc structure, which cannot flexibly adapt to billiard cues of different diameters, and is prone to loose clamping or over-tight clamping, which may damage the billiard cues.

[0004] At the same time, the existing devices often require multiple manual adjustments during the adjustment process of radial clamping and axial pressing, which is complicated and inconvenient to operate and cannot meet the user's needs for ease of operation and efficiency. Therefore, there is a large room for improvement in the existing technology in maintaining pressure stability, adaptability and ease of operation. Summary of the invention

[0005] The present application provides a device for continuously applying pressure to a billiard cue tip. The device for continuously applying pressure according to the present application can overcome at least one or more problems existing in the prior art.

[0006] A device for continuously applying pressure to a billiard cue tip comprises a slide rail, and a pressure holder and a clamp whose fixed positions can be adjusted on the slide rail. The clamp can apply radial pressure to the clamped billiard cue, and the pressure holder can apply axial pressure to the clamped billiard cue.

[0007] The clamp includes two clamping parts, and the clamping distance between the two clamping parts can be adjusted by a fastener; the pressure holder includes a pressure mechanism and a pressure part. The pressure mechanism adjusts the distance between the pressure part and the clamp, and keeps the pressure of the pressure part on the axial direction of the billiard cue unchanged.

[0008] Compared with the prior art, the utility model has the following beneficial effects: the design adjusts the distance between the pressing part and the clamp through the pressing mechanism, ensures that a constant pressure is maintained when the tip and the cue stick are adhered, and improves the stability of the pressing. The clamping part adopts a semi-arc or angled clamping surface and is equipped with a corresponding rubber pad, which can adapt to cue sticks of different diameters. The clamping part can be flexibly moved to adjust the clamping distance through the adjustment of the fastener. The operation of radial clamping and axial pressing is simplified, making the whole process more convenient and efficient.

[0009] In one possible implementation, the clamping portion is a clamping plate, one clamping plate is fixedly connected to the slide rail and is connected to another clamping plate via a fastener, and the clamping distance between the two clamping plates can be changed by adjusting the fastener.

[0010] Further, a slide rail is connected to each side of the clamping center of the clamping plate.

[0011] In another possible implementation, the clamping part is a clamping piece, and two clamping pieces are arranged opposite to each other to form an annular sleeve body with an opening; the two ends of the two clamping pieces away from the opening are respectively connected to the slide rail, and the opening ends are connected by a fastener; by adjusting the fastener, the opening and closing size of the opening can be changed.

[0012] In one possible implementation, semi-circular or angled clamping surfaces are provided on the opposite surfaces of the two clamping parts, and sheet-shaped rubber pads matching their shapes are attached to the clamping surfaces.

[0013] In one possible implementation, the pressing mechanism includes a gun shell, and a holding part adapted to the finger is provided at the bottom of the gun shell; a wrench is rotatably connected to the gun shell on the side of the holding part away from the gripper, a rod-shaped slide rail penetrates through both side surfaces of the gun shell, and two sets of stop components are sleeved on the slide rail in the gun shell; the plate-shaped pressing part at the top of the gun shell is arranged towards the clamping center of the gripper.

[0014] Further, the stop component is composed of a plate-shaped clamping plate and a first spring; a button is slidably connected to the gun shell, the inner end surface of the button abuts against the clamping plate of a set of stop components, and one end of the wrench inside the gun shell abuts against the clamping plate of the other set of stop components; the first spring in the stop component is in a compressed state and abuts against the side of the clamping plate away from the gripper;

[0015] The through hole in the middle of the clamping plate is slightly larger than the outer contour of the slide rail; the clamping plate in one set of stop components is inclined, and the inclined edge of its through hole is stuck on the slide rail to prevent the displacement of the slide rail relative to the clamping plate; the clamping plate in the other set of stop components is perpendicular to the central axis of the slide rail.

[0016] Furthermore, the top of the inclined clamping plate abuts against the convex block inside the gun shell, and the bottom abuts against the inner end surface of the button;

[0017] When the button is withdrawn from the gun shell, the distance between the end surface of the button abutting against the clamping plate and the gripper is less than the distance between the end surface of the convex block abutting against the clamping plate and the gripper, making the clamping plate inclined;

[0018] When the button is inserted into the gun shell, the distance between the end surface of the button abutting against the clamping plate and the gripper is equal to the distance between the end surface of the convex block abutting against the clamping plate and the gripper, making the clamping plate perpendicular to the slide rail;

[0019] At least one limiting block is provided inside the gun shell above the wrench, and the limiting block keeps the adjacent clamping plate perpendicular to the central axis of the slide rail and prohibits the clamping plate from continuing to move towards the gripper side.

[0020] In a possible implementation, the pressing mechanism includes a housing, a sliding rod, and a second spring. The housing is fixed on the slide rail. The sliding rod is slidably connected to the housing and can move along the central axis direction of the slide rail. One end of the sliding rod passes through the housing and is connected to the lifting part. The size of the lifting part is larger than the size of the sliding cavity of the sliding rod in the housing to prevent the sliding rod from slipping out. The other end of the sliding rod is connected to a disc-shaped pressing part.

[0040] It should be understood that in all the drawings, the same reference numerals represent the same elements.

The terms used in the specification are only for describing specific embodiments and are not intended to limit the present application.

For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0041] First embodiment

[0042] Please refer to Figures 1 to 3 , Figures 1 to 3The structure of a continuous pressure device for sticking the tip of a billiard cue is shown from different angles, including a slide rail 10, and a presser and a gripper that can be adjusted and fixed in position on the slide rail 10. The gripper can apply radial pressure to the billiard cue 40 it grips, and the presser can apply axial pressure to the billiard cue 40 it presses.

[0043] Specifically, the gripper includes a single fixed clamp plate 31a, a movable clamp plate 32, and a fastener 35. Semi-circular clamping surfaces 33 are provided on the opposite surfaces of the single fixed clamp plate 31a and the movable clamp plate 32. At least one fastener 35 (a threaded rod with a cap) connects the single fixed clamp plate 31a and the movable clamp plate 32. By adjusting the fastener 35, the movable clamp plate 32 moves towards the single fixed clamp plate 31a, so that the gripper can grip billiard cues 40 with different diameters.

[0044] A sheet-shaped rubber pad 36 matching the shape of the above clamping surface 33 is attached to the clamping surface 33.

[0045] Specifically, the presser includes a gun shell 21 and a pressing plate 213. The end face of the pressing plate 213 at the top of the gun shell 21 is arranged towards the gripper, and a holding part 211 adapted to the finger is provided at the bottom; a wrench 212 is rotatably connected to the gun shell 21 on the side of the holding part 211 away from the pressing plate 213. The above slide rail 10 is a rod-shaped structure and penetrates through both side surfaces of the gun shell 21. Two sets of stop components are sleeved on the slide rail 10 in the gun shell 21; the stop component consists of a plate-shaped clamping plate and a first spring 216; a button 214 is slidably connected to the gun shell 21, and the inner end face of the button 214 abuts against the clamping plate of a set of stop components, and the end of the wrench 212 inside the gun shell 21 abuts against the clamping plate of the other set of stop components; the first spring 216 in the stop component is in a compressed state and abuts against the side of the clamping plate away from the gripper.

[0046] One end of the first spring 216 abuts against the clamping plate, and the other end is fixed inside the gun shell 21.

[0047] Further, the size of the through hole in the middle of the clamping plate is slightly larger than the outer contour of the slide rail 10, mainly reflected in the longitudinal dimension, that is, the dimension in the direction from the button 214 to the pressing plate 213; the clamping plate in one set of stop components is inclined, that is, Figure 3 the normally closed clamping plate 215a therein, and the inclined through hole edge of it is stuck on the slide rail 10 to prevent the displacement of the slide rail 10 relative to the clamping plate; the clamping plate in the other set of stop components is perpendicular to the slide rail 10, that is, Figure 3 the normally open clamping plate 215b therein.

[0048] In order to maintain the inclined state of the normally closed clamping plate 215a, the top of the normally closed clamping plate 215a abuts against the convex block 217 inside the gun shell 21, and the bottom abuts against the inner end face of the button 214.

[0049] When the button 214 exits the gun housing 21, the distance between the end face of the button 214 against the normally closed latch plate 215a and the gripper is less than the distance between the end face of the bump 217 against the normally closed latch plate 215a and the gripper, causing the latch plate to be in an inclined state;

[0050] When the button 214 is inserted into the gun housing 21, the distance between the end face of the button 214 against the normally closed latch plate 215a and the gripper is equal to the distance between the end face of the bump 217 against the normally closed latch plate 215a and the gripper, causing the latch plate to be perpendicular to the slide rail 10.

[0051] At least one limiting block 218 is provided above the wrench 212 inside the gun housing 21. The limiting block 218 keeps the normally open latch plate 215b perpendicular to the slide rail 10 and prohibits the normally open latch plate 215b from moving further towards the gripper side.

[0052] Combined Figure 11 As shown, in use, the billiard cue 40 is clamped in the gripper. By pressing the wrench 212 towards the holding portion 211, at this time, one end of the wrench 212 inside the gun housing 21 pushes the normally open latch plate 215b to move towards the side away from the gripper. Since the force applied acts on one end of the normally open latch plate 215b, the normally open latch plate 215b is in an inclined state and moves towards the side away from the gripper; for the normally open latch plate 215b in an inclined state, the top edge of its through hole is stuck on the slide rail 10. As the normally open latch plate 215b moves, it drives the slide rail 10 to move synchronously relative to the gun housing 21.

[0053] Because the normally closed latch plate 215a remains in an inclined state and is stuck on the slide rail 10, during the movement of the slide rail 10, the adjacent first spring 216 of the normally closed latch plate 215a will be slightly deformed, causing the normally closed latch plate 215a to be slightly straightened to allow the slide rail 10 to pass through; when the external force is removed from the wrench 212, the latch plates (the normally closed latch plate 215a and the normally open latch plate 215b) are squeezed by the adjacent springs and return to the initial state; by repeatedly pressing the wrench 212, the gun housing 21 drives the pressure plate 213 to gradually move towards the gripper side.

[0054] When the newly replaced tip 41 is bonded to the billiard cue 40, continuous pressing is required for a period of time. When the pressure plate 213 presses against the tip 41, the stop assembly where the normally closed latch plate 215a is located, through the frictional force and the elastic force of the first spring 216, is sufficient to maintain the required pressure and prevent the slight rebound force of the tip 41 from causing the presser to move away from the gripper.

[0055] Second Embodiment

[0056] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5Shows the structure of another holder from different perspectives, including a housing 22, a slide rod 221, a second spring 223, a screw rod 225, and a constant pressure plate 224a. The housing 22 is fixed on the slide rail 10. The slide rod 221 is slidably connected to the housing 22 and can move along the direction of the slide rail 10. One end of the slide rod 221 is connected to the constant pressure plate 224a, and the other end passes through the housing 22 and is connected to the lifting part 222. The size of the lifting part 222 is larger than the size of the sliding cavity of the slide rod 221 in the housing 22 to prevent the slide rod 221 from slipping out. The second spring 223 is in a compressed state, sleeved outside the slide rod 221, and located between the constant pressure plate 224a and the housing 22.

[0057] The slide rod 221 is coaxial with the clamping center of the holder, and one end of the constant pressure plate 224a facing the holder is an arc surface adapted to the leather head 41.

[0058] In one implementation, a screw rod 225 is arranged radially along the slide rod 221 on the side of the housing 22. After the screw rod 225 is screwed in, its inner end face can abut against the side face of the slide rod 221. If the leather head 41 is deformed greatly under pressure, the rebound of the second spring 223 can be restricted by tightening the screw rod 225, thereby reducing the pressure on the leather head 41.

[0059] Third Embodiment

[0060] Please refer to Figure 6 and Figure 7 , Figure 6 and Figure 7 Shows the structure of the third holder from different perspectives, including a housing 22, a T-shaped lead screw 226, a nut sleeve 227, and a moving pressure plate 224b. The T-shaped lead screw 226 is connected to the housing 22 through the nut sleeve 227 and can move along the direction of the slide rail 10. One end of the T-shaped lead screw 226 close to the holder is connected to the moving pressure plate 224b through a spherical joint. The T-shaped lead screw 226 can be self-locking.

[0061] The T-shaped lead screw 226 is coaxial with the clamping center of the holder, and one end of the moving pressure plate 224b facing the holder is an arc surface adapted to the leather head 41.

[0062] Fourth Embodiment

[0063] Please refer to Figure 8 , Figure 8A continuous pressure-applying device for sticking the tip of a billiard cue with a double slide rail is presented. Different from the third embodiment, in the holder, a slide rail 10 is provided on each side of the housing 22 in the press holder along the T-shaped lead screw 226; in the gripper, semi-circular clamping surfaces 33 are provided on the opposite surfaces of the double fixed clamping plates 31b and the movable clamping plate 32; the double fixed clamping plates 31b are respectively connected to a slide rail 10 on both sides of the clamping surface 33; at least one threaded rod with a cap is used as a fastener 35 to connect the double fixed clamping plates 31b and the movable clamping plate 32; by adjusting the fastener 35, the movable clamping plate 32 can be moved towards the double fixed clamping plates 31b.

[0064] The Fifth Embodiment

[0065] Please refer to Figure 9 , Figure 9 The structure of the third gripper is presented. The gripper includes two semi-circular clamping pieces 34 which are oppositely arranged to form an annular sleeve body with an opening; the two ends of the clamping pieces 34 far away from the opening are respectively connected to the slide rail 10, and the opening ends are connected through the fastener 35; by adjusting the fastener 35, the opening size of the opening can be changed, so as to adjust the clamping range of the gripper for the billiard cue 40 (i.e., the clamping of billiard cues 40 with different diameters).

[0066] In some embodiments, as Figure 10 shown, the clamping surface 33 is changed from an arc to a corner surface, that is, two planes are arranged at an angle; the clamping piece 34 in the fifth embodiment can also adopt a corner surface design.

[0067] Although the exemplary embodiments of the present application have been described, those skilled in the art should understand that various changes and modifications can be made to the exemplary embodiments of the present application without substantially departing from the spirit and scope of the present application.
