Description

Technical Field

[0001] This application relates to the field of sports equipment repair tools, and in particular to a cue tip grinding groove and tip repairer. Background Technology

[0002] In the current technological context, there are numerous publicly disclosed utility models concerning improvements to billiard cue tip grinding devices, such as Chinese utility model publications CN209033698U, CN204582520U, and CN205145575U, and US invention publication US20100311314A1. The devices described in these technical documents generally employ adhesive bonding between the grinding disc and the groove, or the processing of grinding textures on the groove to fix the grinding disc.

[0003] However, these traditional connection methods have drawbacks, especially when the grinding disc is made of a metal material with a high elastic modulus. Due to its inherent large rebound force, the metal grinding disc tends to return to its original flat shape, which makes it difficult to bond the grinding disc during the installation and production process and easy to fall off during use. Summary of the Invention

[0004] In a first aspect, this application provides a grinding groove for a billiard cue tip, including a groove body and a grinding disc. The groove body has an arc-shaped cross-section in the width direction, and the grinding disc covers the support surface of the groove body. The first side of the groove body engages with the first side edge of its adjacent grinding disc.

[0005] In one possible implementation, the first side of the groove faces the grinding disc and is set at an angle to the horizontal plane.

[0006] In one possible implementation, a retaining edge is provided on the first side of the groove, and the first side of the grinding disc is held by the retaining edge and the support surface.

[0007] In one possible implementation, the angle between the first side of the tank and the horizontal plane is α, where α = (180° - central angle of the tank) / 2.

[0008] In one possible implementation, the aforementioned support surface is provided with at least one limiting body that restricts the movement of the grinding disc.

[0009] In one possible implementation, the limiting body is a stop, which is a block-shaped body set on the support surface, and the second side of the grinding disc abuts against the stop.

[0010] In one possible implementation, the limiting body is a baffle that is positioned upward at the outer edge of the support surface.

[0011] In one possible implementation, the limiting body is a screw, which is detachably connected to a screw hole on the support surface, with the outer edge of the top surface of the screw abutting against the grinding disc.

[0012] In one possible implementation, the limiting body is a pressure block, the bottom surface of which is adapted to the contour of the support surface. The pressure block is fixed to the support surface and at least partially presses against the grinding disc.

[0013] Compared with the prior art, this utility model has the following advantages: by setting a first side on each side of the tank, the grinding disc can make close contact with the side of the tank through its own elasticity after the external bending force is removed, which solves the problems of metal incompatibility with adhesive, low bonding yield, and easy damage during use; it supports quick installation / replacement of grinding discs without the use of adhesive, simplifying the installation / replacement process.

[0014] In a second aspect, this application also provides a cue tip repairer, including the aforementioned cue tip polishing groove.

[0015] It should be noted that any of the possible implementations of any of the above aspects can be combined, provided that the solutions do not contradict each other. Attached Figure Description

[0027] The present application will now be described with reference to the accompanying drawings, which illustrate several embodiments of the present application. However, it should be understood that the present application can be presented in many different ways and is not limited to the embodiments described below; in fact, the embodiments described below are intended to make the disclosure of the present application more complete and to fully illustrate the scope of protection of the present application to those skilled in the art. It should also be understood that the embodiments disclosed herein can be combined in various ways to provide more additional embodiments.

[0028] Firstly, the first embodiment of this application provides a grinding groove for the tip of a billiard cue, which can be seen in conjunction with the following: Figures 1 to 3 The grinding groove includes a groove body 10 and a grinding disc 20. The groove body 10 has an arc-shaped cross-section in the width direction. The upper surface of the groove body 10 is a long arc-shaped support surface 11. The grinding disc 20 covers the support surface 11 of the groove body 10. The side of the groove body 10 in the length direction is a first side surface 12. There is a first side surface 12 on each side of the groove body 10. The first side surface 12 of the groove body 10 is engaged with the first side edge 21 (i.e., the long side) of the adjacent grinding disc 20.

[0029] The first side 12 of the groove 10 faces the grinding disc 20 and forms an angle α with the horizontal plane. The preferred angle α is between 0° and (180° - central angle of the groove) / 2. Figure 2 As shown, α equals (180° - central angle of the groove) / 2, ensuring that the first side surface 12 of the groove 10 and the end face of the first side edge 21 of the grinding disc 20 are in close face-to-face contact. The grinding disc 20 is made of stainless steel with electroplated grinding particles on the surface, and has a high elastic modulus. Under the action of its own elastic restoring force, the contact pressure between the first side surface 12 and the end face of the first side edge 21 of the grinding disc 20 increases, thereby improving the snap-fit ​​effect and potentially reducing or avoiding the use of adhesives to prevent the high elastic modulus grinding disc 20 from bending under external force and becoming loosely bonded to the arc-shaped groove 10.

[0030] In order to restrict the movement of the grinding disc 20 in the length direction of the groove 10, a baffle 32 is provided on at least one side of the outer edge of the support surface 11. The baffle 32 is plate-shaped and can be set slightly higher than the support surface 11; or it can be set to block the entire end face of the groove 10.

[0031] like Figure 4In the second embodiment of this application shown, a retaining edge 121 is provided on the first side 12 of the groove 10. The retaining edge 121 extends along the outer edge of the first side 12 in the length direction of the groove 10 and can be continuous or discontinuous. The first side 21 of the grinding disc 20 is held by the retaining edge 121 and the support surface 11.

[0032] like Figure 5 In the third embodiment of this application shown, at least one stop 31 for restricting the movement of the grinding disc 20 is provided on the support surface 11. The stop 31 is a block-shaped body, and the second side (i.e. the short side) of the grinding disc 20 abuts against the stop 31. When grinding, although the cue tip rotates circumferentially, manual rotation inevitably generates a force that pushes the cue outward. The stop 31 can prevent the grinding disc 20 from moving in the length direction of the groove 10.

[0033] like Figure 6 In the fourth embodiment of this application shown, the support surface 11 is provided with at least one screw hole, and the screw 33 is detachably connected to the screw hole. The outer edge of the top surface of the screw 33 abuts against the grinding disc 20, specifically against the second side of the grinding disc 20.

[0034] like Figure 7 In the fifth embodiment of this application shown, the support surface 11 is provided with at least one screw hole, and the screw 33 passes through the grinding disc 20 and is detachably connected to the screw hole. The outer edge of the top surface of the screw 33 abuts against the grinding disc 20, specifically against the inner edge of the through hole of the grinding disc 20.

[0035] like Figure 8 In the sixth embodiment of this application shown, a pressure block 34 is connected to at least one end of the support surface 11. The bottom surface of the pressure block 34 is adapted to the contour of the support surface 11, and the pressure block 34 presses all or part of the grinding disc 20.

[0036] Secondly, the seventh embodiment of this application also provides a tip repair tool; please refer to [link to relevant documentation]. Figure 9 The cue tip repairer includes the aforementioned cue tip grinding groove.

[0037] Assembly Method: The grinding disc 20 body is typically made of metal and has a high elastic modulus, thus exhibiting significant resilience. In traditional methods, the grinding disc 20 is often fixed to the groove 10 by adhesive bonding. However, due to the high resilience of the grinding disc 20, it tends to revert to its original flat shape, often leading to detachment or bonding difficulties. Furthermore, the poor affinity between adhesive and metal also reduces the yield rate. In this invention, a first side surface 12 is provided on each side of the groove 10. When the bending force is removed, the resilience of the grinding disc 20 presses its two sides tightly against the adjacent first side surface 12 of the groove 10. This structure effectively prevents detachment caused by non-adhesion due to resilience deformation. Therefore, this technology can reduce or completely eliminate the use of adhesives.

[0038] Replacement method: After removing the object used for limiting, the grinding disc 20 can be removed from the groove 10 by pushing / pulling it along the length of the groove 10. It should be noted that for models where the grinding disc 20 is clamped by the retaining edge 121, more force needs to be applied when removing it.

[0039] While exemplary embodiments of this application have been described, those skilled in the art will understand that various changes and modifications can be made to the exemplary embodiments of this application without departing from the spirit and scope thereof. Therefore, all changes and modifications are included within the scope of protection of this application as defined by the claims.
