Description

Technical Field

[0001] This application relates to the technical field of tools, and particularly to a leather tip grinding head for a billiard cue. Background Art

[0002] There are mainly two technical solutions for existing billiard cue leather tip grinding devices: The first is to use a sharpener similar to a pencil sharpener for rough turning, and then use the arc-shaped file plate of the sharpener for fine grinding. This method can effectively remove excess material and make the shape of the leather tip more regular; the second solution is to use a hand-held electric grinder, cooperating with an arc-shaped grinding head for grinding. The grinding head is usually integrally made of silicon carbide or alumina materials, or the grinding sheet is glued to the arc-shaped grinding head body, which has high efficiency; however, the grinding head of this solution is prone to failure, mainly due to the wear of the grinding particles or the gaps between the particles being filled with leather tip debris, resulting in a relatively high replacement frequency. Summary of the Invention

[0024] The present application will be described below with reference to the accompanying drawings, which show 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 fully explain 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.

[0025] It should be understood that in all the drawings, the same reference numerals denote the same elements. In the drawings, for clarity, the dimensions of some features may be distorted. The terminology used in the specification is only for describing specific embodiments and is not intended to limit the present application. All terms used in the specification (including technical terms and scientific terms) have the meaning commonly understood by those skilled in the art unless otherwise defined. For the sake of brevity and / or clarity, well-known functions or structures may not be described in detail.

[0026] Embodiments of the present application provide a billiard cue tip grinding head. Please refer to Figure 1 and Figure 2 , Figure 1 and Figure 2 , which show the structure of the grinding head from different angles, including a base body 10, a cover body 30, and a rimless grinding disc 20a. One end of the base body 10 is connected to a hand-held electric grinder, and the other end is installed with the rimless grinding disc 20a. The cover body 30 is connected to the base body 10 and presses against the outer edge of the rimless grinding disc 20a. The rimless grinding disc 20a is designed with an arc surface.

[0027] Specifically, one end of the base body 10 is provided with a cylindrical clamping portion 12 for connecting with the clamping port of the hand-held electric grinder; the end far from the clamping portion 12 is provided with a hemispherical placement groove 11, and the sheet-shaped rimless grinding disc 20a adheres to the contour of the placement groove 11. A window is opened in the center of the cover body 30 to allow the head of the billiard cue to pass through, so that the tip can contact the rimless grinding disc 20a pressed by the cover body 30.

[0028] In a possible implementation manner, the outer wall of the cover body 30 is provided with embossed anti-slip textures.

[0029] Preferably, the cover body 30 and the base body 10 are connected by threads.

[0030] Please refer to Figure 3 , Figure 3 , which shows the structure of a rimless grinding disc 20a. The grinding disc is sheet-shaped, spherical crown-shaped, and its surface is provided with grinding textures. Usually, the grinding textures are made of silicon carbide, alumina, or emery materials, and can also be processed by the barbed iron sheet process, suitable for grinding. A plurality of evenly distributed cuts 21 extend from the outer edge of the rimless grinding disc 20a towards the center. The design of the cuts 21 facilitates the planar grinding disc to be bent into a spherical crown shape by stamping.

[0031] Further explanation, the incision 21 is in a "U" shape, and the distance between the open ends is smaller than the distance at the connection.

[0032] Please refer to Figure 4 and Figure 5 , Figure 4 and Figure 5 which show the structures of two types of flanging abrasive discs 20b. The abrasive disc is in a thin sheet shape, in a spherical crown shape, with grinding textures provided on the surface, and a pressing portion 22 that is folded outward is provided at the outer edge, and the pressing portion 22 is arranged as a horizontal thin sheet; several evenly distributed incisions 21 also extend from the outer edge of the flanging abrasive disc 20b towards the center.

[0033] In order to facilitate the folding of the pressing portion 22, several cutting grooves 221 are provided on the outer edge of the pressing portion 22, and the cutting grooves 221 can be in a "|" shape or a "V" shape.

[0034] As Figure 6 shown, one side of the borderless abrasive disc 20a is covered by the placement groove 11 on the seat body 10, and the outer edge of the other side is pressed by the cover body 30. Specifically, an inner edge of the central window of the cover body 30 extends inward to form a sheet-like flange 31. In Figure 6 , this flange 31 is a whole-week ring shape, or can also be a discontinuous structure. The cover body 30 and the seat body 10 jointly clamp the borderless abrasive disc 20a to prevent it from rotating circumferentially. Therefore, when the grinding surface of the borderless abrasive disc 20a fails, the cover body 30 can be quickly unscrewed and a new borderless abrasive disc 20a can be replaced. The borderless abrasive disc 20a is in a flat sheet shape in the storage state, occupies a small space, and when replacing, relying on the shape of the placement groove 11, it can be pressed into a spherical crown shape with fingers, and the operation is convenient.

[0035] As Figure 7 shown, one side of the flanging abrasive disc 20b is covered by the placement groove 11 on the seat body 10, the pressing portion 22 rests on the end surface of the seat body 10, and the flange 31 on the inner edge of the central window of the cover body 30 presses on the pressing portion 22 of the flanging abrasive disc 20b, thereby preventing the flanging abrasive disc 20b from rotating circumferentially.

[0036] Although the exemplary embodiments of the present application have been described, those skilled in the art should understand that various changes and alterations can be made to the exemplary embodiments of the present application without essentially departing from the spirit and scope of the present application. Therefore, all changes and alterations are included within the protection scope of the present application defined by the claims. The present application is defined by the appended claims, and equivalents of these claims are also included.
