[0029] To address the problems in traditional polishing processes where fixing and disassembling polishing discs typically relies on bolt connections, which is time-consuming, labor-intensive, and prone to operator fatigue, this utility model provides an easily detachable polishing disc. The technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] Please see Figures 1-5 This utility model provides an easily detachable polishing disc, including a polishing disc body 1. A polishing machine mounting base 2 is provided at the lower part of the polishing disc. A connecting component 3 is located at the bottom of the polishing disc body 1. The connecting component 3 includes an outer sleeve 301 located in the middle of the polishing disc body 1. A locking rod 302 is slidably connected inside the outer sleeve 301. A locking seat plate 3022 is provided at the bottom of the locking rod 302. A receiving groove 303 is formed on the inner wall of the outer sleeve 301 at the locking seat plate 3022. A locking bead 304 is disposed inside the receiving groove 303. A concave groove 3021 is formed at the lower part of the locking rod 302, and the concave groove 3021 is located above the locking seat plate 3022. The lower part of the receiving groove 303 is obliquely arc-shaped to allow the locking bead 304 to roll along the bottom wall of the receiving groove 303 towards the locking rod 302. The upper part of the locking rod 302 is provided with a top plate 305, and limit plates 306 are provided on both sides below the top plate 305. The upper part of the outer sleeve 301 is provided with a limiting groove 307 for the movement of the limit plates 306. A return spring 308 is provided directly below the limit plates 306 in the limiting groove 307, and the return spring 308 is located on the outer periphery of the locking rod 302.

[0031] The loading base 2 is provided with a loading cylinder 4 in the middle; the inner wall of the loading cylinder 4 is provided with a positioning ball groove 401 for connecting the locking ball 304, and the position of the positioning ball groove 401 is matched with the position of the receiving groove 303.

[0032] The polishing disc body 1 is connected to the loading cylinder 4 of the loading seat 2 via the connecting component 3.

[0033] The working principle of the easy-to-disassemble polishing disc provided by this utility model is as follows:

[0034] Installation of polishing disc body 1: Place polishing disc body 1 on top of loading base 2, ensuring that the outer sleeve 301 at the bottom of polishing disc body 1 is aligned with the loading sleeve 4 of loading base 2.

[0035] Press the top plate 305, and the top plate 305 will squeeze the return spring 308 located inside the limit slide groove 307 through the limit plate 306. The return spring 308 will be compressed and deformed. At the same time, the locking rod 302 will move down until the concave groove 3021 moves to the side of the locking bead 304. The locking bead 304 will roll along the receiving groove 303 to the upper side of the locking seat plate 3022.

[0036] Insert the outer sleeve 301 into the loading sleeve 4 so that the locking bead 304 is located next to the positioning ball groove 401;

[0037] When the pressing action on the top plate 305 is released, the return spring 308 is subjected to force and elastically elongates, controlling the locking seat plate 3022 to move upward, and the locking ball 304 abuts against the inside of the positioning ball groove 401 through the receiving groove 303. The outer sleeve 301 is connected and fixed to the loading cylinder 4 through the locking ball 304, thus completing the connection between the polishing disc and the polishing machine.

[0038] To remove the polishing disc body 1, press the locking plate again, the locking seat plate 3022 moves down, the locking bead 304 rolls to the concave groove 3021, remove the polishing disc body 1, and disconnect the connection between the outer sleeve 301 and the loading sleeve 4.

[0039] The radii of the channels on both sides of the receiving groove 303 are smaller than the radius of the locking bead 304. The locking bead 304 rolls within the receiving groove 303 and will not detach or fall off.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
