Description

Technical Field

[0001] This utility model relates to the field of polishing technology, to polishing discs, and particularly to a quick-change polishing disc structure. Background Technology

[0002] A polishing pad is a tool used to polish the surfaces of materials such as metal, plastic, and wood. It is typically used to remove scratches, oxide layers, or other imperfections from the material surface to achieve a smooth and shiny finish.

[0003] For example, the patent with authorization announcement number CN218891694U provides a floating polishing head, wherein a high-resilience base layer is provided on the bottom of the polishing turntable, and a polishing pad is detachably provided on the bottom of the high-resilience base layer via Velcro.

[0004] When changing the polishing pad, the size of the polishing pad must be less than or equal to the size of the high-resilience base layer or polishing disc. It cannot be used to fit larger polishing pads, which reduces the compatibility. If a larger polishing pad is required, the polishing disc must be replaced, which is a more complicated operation.

[0036] The preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Those skilled in the art will appreciate that these descriptions are merely descriptive and exemplary and should not be construed as limiting the scope of protection of the present invention.

[0037] It should be noted that similar labels in the following figures indicate similar items; therefore, once an item is defined in one figure, it may not be further defined and explained in subsequent figures.

[0038] This embodiment mainly describes the quick-change polishing disc structure that is easy to install and remove when adapting to polishing pads of different sizes, as detailed below:

[0039] Example 1

[0040] like Figure 1-3 As shown, the quick-change polishing disc structure includes a main mounting disc 1, a magnet 3, and a detachable disc 2. The detachable disc 2 is made of a rigid material. The main mounting disc 1 and the detachable disc 2 are detachably installed via the magnet 3. The main mounting disc 1 is provided with a connecting part 11 for mounting on a polishing machine, and the detachable disc 2 is connected to a polishing pad via Velcro (the polishing machine, Velcro, and polishing pad are not shown in the attached drawings). The diameters of the detachable disc 2 and the polishing pad are basically the same. Preferably, the polishing pad may include sandpaper, sponge, etc.

[0041] In this embodiment, the main mounting plate 1 is provided with a fitting part 12 whose outer size is larger than that of the connecting part 11, and a plurality of pins 13 are provided on the lower end surface of the fitting part 12. The pins 13 are offset from the fitting part 12, that is, the pins 13 are located on the outer ring of the connecting part 11. The detachable plate 2 is provided with pin holes 21 that can be inserted and matched with the pins 13 one by one. When the pins 13 are matched with the pin holes 21, they can restrict the detachable plate 2 from rotating synchronously with the main mounting plate 1.

[0042] Preferably, the pin 13 and the pin hole 21 are interchangeable on the main mounting plate 1 and the detachable plate 2.

[0043] The main loading tray 1, magnet 3, and removable tray 2 are configured in the following ways.

[0044] Scenario 1: For example Figure 2-3 As shown, the main tray 1 has a plurality of mounting holes 14 on the bonding part 12, the magnet 3 is embedded in the mounting holes 14, and the detachable tray 2 is made of a ferromagnetic material that can be attracted by the magnet 3. The detachable tray 2 is attached to the bonding part 12 of the main tray 1 by attracting the magnet 3.

[0045] Scenario 2: The main tray 1 has multiple mounting holes 14 on its bonding part 12 or the detachable tray 2. Magnets 3 are embedded in the mounting holes 14. The detachable tray 2 and the bonding part 12 of the main tray are attracted and bonded by the magnets 3.

[0046] Scenario 3: The main tray 1 is made of a ferromagnetic material that can be attracted by magnets 3, and the detachable tray 2 is equipped with multiple mounting holes 14. Magnets 3 are embedded in the mounting holes 14, and the main tray 1 is attracted and attached to the attachment part 12 of the main tray 1 by magnets 3.

[0047] like Figure 4 As shown, when the outer dimensions of the removable tray 2 are close to or smaller than the outer dimensions of the main tray 1 fitting part 12, the removable tray 2 can adopt a planar structure.

[0048] like Figure 1-3 As shown, when the outer size of the removable disc 2 is larger than the outer size of the mating part 12 of the main disc 1, in order to reduce the probability of deformation of the removable disc 2, the removable disc 2 is provided with a recessed receiving cavity 22, and the pin hole 21 is opened at the bottom of the receiving cavity 22. When the magnet 3 adsorbs and connects the main disc 1 and the removable disc 2, the mating part 12 of the main disc 1 is located in the receiving cavity 22.

[0049] The outer ring of the receiving cavity 22 is provided with an outer edge 23. The upper end face of the outer edge 23 is lower than the upper end face of the cavity wall of the receiving cavity 22, and the lower end face of the outer edge 23 is flush with the lower end face of the receiving cavity 22. Preferably, the cavity wall of the receiving cavity 22 can be used as a reinforcing rib, and the detachable plate 2 can be formed by stamping a sheet of ferromagnetic material or the like.

[0050] In this application, the polishing disc is equipped with a main mounting disc 1 connected to the polishing machine, a detachable disc 2 magnetically connected to the main mounting disc 1, and a polishing pad connected to the detachable disc 2 via Velcro. The rigid material of the detachable disc 2 allows it to be adapted to polishing pads of different sizes by replacing the detachable disc 2 of different sizes, thus improving compatibility. Furthermore, the magnetic connection of the detachable disc 2 makes it easy to install and remove.

[0051] Example 2

[0052] like Figure 5-6 As shown, the structural features that differ from those in Embodiment 1 are that the pin hole 21 on the main mounting plate 1 is divided into a bayonet 21a and a movable opening 21b. A limiting part 21c is left between the bayonet 21a and the outer wall of the removable plate 2, and the movable opening 21b disconnects the limiting part 21c from the outer wall of the removable plate 2, so that the movable opening 21b connects the bayonet 21a and the outer wall of the removable plate 2. The pin 13 on the removable plate 2 is divided into an insertion part 13a that can move in the bayonet 21a or the movable opening 21b, and a stop part 13b that moves in the movable opening 21b. When the polishing machine drives the main mounting plate 1 to rotate, the insertion part 13a can be inserted into the bayonet 21a, and the insertion part 13a abuts against the side wall of the bayonet 21a, or the stop part 13b abuts against the limiting part 21c. Preferably, the direction of the bayonet 21a in the movable opening 21b is opposite to the direction of the polishing machine driving the main mounting plate 1 to rotate.

[0053] Preferably, the size of the movable opening 21b is larger than the size of the stop part 13b, so as to facilitate the installation of the pin hole 21 on the main mounting plate 1 and the pin 13 on the detachable plate 2, and the pin hole 21 and the pin 13 can each be L-shaped.
