[0002] Grinding wheels are mainly used for grinding, polishing, and finishing of materials such as metal, stone, and glass. They are typically used to sharpen various knives and tools. However, in actual use, we have found that traditional grinding wheels are fixed with special nuts, so disassembly and replacement require special tools, which is time-consuming and laborious. Moreover, if the disassembly and replacement tools are lost, the grinding wheel cannot be disassembled or replaced, which greatly affects the user's replacement and use.

[0003] To address the aforementioned problems, this utility model provides improvements. Summary of the Invention

[0021] The following will refer to the appendix in the embodiments of this utility model. Figure 1-4 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example

[0022] A resin grinding wheel with moisture-proof function includes a grinding wheel body 1. A drive shaft 2 is fixedly installed on the output shaft of the grinding wheel body 1. A locking block 3 is provided on one side of the top of the drive shaft 2. A spring 4 is fixedly connected to the side of the locking block 3 facing the drive shaft 2. The end of the spring 4 away from the locking block 3 is fixedly connected to the inner wall of the drive shaft 2. One end of the locking block 3 extends into the inner cavity of the drive shaft 2. A rotating shaft seat 5 is fixedly connected to one side of the top of the drive shaft 2. A rotating pin 6 is slidably installed in the inner cavity of the rotating shaft seat 5. A pad 8 that matches the drive shaft 2 and the locking block 3 is fixedly connected to the top of the rotating pin 6. A torsion spring 7 is sleeved on the surface of the rotating pin 6. The two ends of the torsion spring 7 are fixedly connected to the pad 8 and the rotating shaft seat 5, respectively.

[0023] This utility model adopts a quick-release grinding wheel positioning and locking structure design, using an eccentric cam and a spring buckle locking structure to replace the traditional bolt locking and fixing. It can quickly complete the disassembly and replacement of the grinding wheel in a very short time, improving the speed and efficiency of grinding wheel replacement and providing convenience and assistance for users' work.

[0024] The specific usage process is as follows: When disassembling the grinding wheel 12, the pad 8, which is stuck between the drive shaft 2 and the locking block 3, is rotated outward and moved out. The pad 8 will drive the rotating pin 6 to rotate within the rotating shaft seat 5. At the same time, the pad 8 will twist the torsion spring 7. Simultaneously, the rotating pin 6 will drive the pad 8 to move downward within the rotating shaft seat 5. When the pad 8 rotates 180 degrees to the recessed area on the inner side of the drive shaft 2, the locking block 3, which was originally pushed outward by the pad 8, is pulled downward by the spring 4. The bottom of the locking block 3 adheres to the inner wall of the drive shaft 2. At the same time, the locking block 3 will also drive the limiting slide rod 10 to slide within the movable cavity 9. At this time, the distance between the locking block 3 and the drive shaft 2 will decrease until the sum of the vertical widths of the locking block 3 and the drive shaft 2 is less than that of the grinding wheel 12. With the inner diameter adjusted, the grinding wheel 12 can be removed from the drive shaft 2 and the locking block 3. After the grinding wheel 12 is removed, the pad 8 is released. Under the action of the torsion spring 7, the pad 8 will be driven back to its original position, thereby pushing the locking block 3 upward. At the same time, the locking block 3 will stretch the spring 4, and the locking block 3 will also drive the limiting slide rod 10 to move upward in the movable cavity 9. At the same time, the rotating pin 6 will also move upward in the rotating shaft seat 5 until the pad 8 is locked between the locking block 3 and the drive shaft 2. When installing the grinding wheel 12, follow the above operation process to rotate the pad 8 outward by 180 degrees to shorten the vertical length of the locking block 3 and the drive shaft 2. Then, the grinding wheel 12 is fitted onto the drive shaft 2 and the locking block 3. On block 3, until the grinding wheel 12 is attached to the grinding wheel pad 11, then release the pad 8. Under the action of the torsion spring 7, the pad 8 will be driven back to its original position, thereby pushing the locking block 3 upward. At the same time, the locking block 3 will stretch the spring 4, and the locking block 3 will also drive the limiting slide rod 10 to move upward in the movable cavity 9. At the same time, the rotating pin 6 will also move upward in the rotating shaft seat 5 until the pad 8 is locked between the locking block 3 and the drive shaft 2, thus padding between the locking block 3 and the drive shaft 2. The distance between the drive shaft 2 and the locking block 3 increases, and the vertical length between the drive shaft 2 and the locking block 3 is greater than the inner diameter of the grinding wheel 12. At this time, the side of the locking block 3 will also lock onto the side of the locking block 3, thus locking the locking block 3 onto the side of the grinding wheel 12. Simultaneously, the locking block 3 will also push the grinding wheel 12 upwards until the inner wall of the grinding wheel 12 is locked in the recess at the bottom of the transmission shaft 2. In this way, with the cooperation of the transmission shaft 2 and the locking block 3, the grinding wheel 12 is fixed on the transmission shaft 2, completing the disassembly and replacement of the grinding wheel 12. This achieves quick disassembly and replacement of the grinding wheel and is not limited by tool loss, providing convenience and assistance for users' disassembly and replacement work. Therefore, the design of the quick-release grinding wheel positioning and locking structure adopts an eccentric cam and a spring buckle locking structure to replace the traditional bolt locking and fixing. It can quickly complete the disassembly and replacement of the grinding wheel in a very short time, improving the speed and efficiency of grinding wheel replacement of the grinding wheel machine, and providing convenience and assistance for users' work.

[0025] A limiting slide rod 10 is fixedly connected to one side of the bottom of the card block 3, and a movable cavity 9 adapted to the limiting slide rod 10 is opened on one side of the bottom of the inner cavity of the transmission shaft 2.

[0026] Specifically, the movable cavity 9 and the limiting slide bar 10 are designed so that when the grinding wheel 12 is installed, the locking block 3 moves up and down inside the transmission shaft 2, which also drives the limiting slide bar 10 to move inside the movable cavity 9. This limits the locking block 3, ensures the stability of the locking block 3's movement, and prevents the locking block 3 from detaching from the transmission shaft 2, thus providing convenience for the user's installation work.

[0027] A grinding wheel pad 11 is fitted on one side of the surface of the drive shaft 2, and a grinding wheel 12 is fastened to the surface of the drive shaft 2 by a locking block 3. The grinding wheel 12 is in close contact with the side of the grinding wheel pad 11.

[0028] Specifically, the grinding wheel pad 11 and the grinding wheel 12 are installed on the drive shaft 2 and are positioned between the grinding wheel 12 and the grinding machine body 1. This is to prevent the grinding wheel 12 from damaging the grinding machine body 1 during operation, thus protecting the grinding machine and providing convenience and protection for the user's work.

[0029] A protective cover 13 is fixedly connected to one side of the top of the grinding wheel body 1, and the protective cover 13 covers the grinding wheel 12.

[0030] Specifically, the protective cover 13 is fixed to the main body 1 of the grinding wheel and covers the outside of the grinding wheel 12. This can prevent the sparks generated during cutting from splashing everywhere, protect the user, improve the safety of the user's work, and provide convenience for the user's work.

[0031] The grinding machine body 1 has a base 14 at its bottom and a sleeve seat 16 fixedly installed on the top of the base 14. The grinding machine body 1 is located inside the sleeve seat 16. Sleeves 15 are fitted on both sides of the top of the grinding machine body 1. Fastening bolts 17 are provided through both sides of the top of the sleeves 15. The sleeves 15 are fixedly installed on the sleeve seat 16 by the fastening bolts 17.

[0032] Specifically, the base 14, sleeve 15, sleeve seat 16, and fastening bolt 17 are arranged such that the base 14 is used to install the grinding machine onto the workbench for operation, in order to meet more usage scenarios and needs, and to provide convenience and assistance for users' work. The grinding machine body 1 is installed inside the sleeve seat 16, and then two sleeves 15 are used to sleeve the sleeve seat 16. Finally, the sleeves 15 and the grinding machine body 1 are fixed with fastening bolt 17 to ensure the stability of the grinding machine body 1 during operation.

[0033] The bottom of the drive shaft 2 is provided with an arc-shaped groove that matches the grinding wheel 12, and one end of the drive shaft 2 is provided with a 30-degree inclined surface that matches the pad block 8.

[0034] Specifically, the arc-shaped groove and the inclined surface are designed so that when the grinding wheel 12 is installed, the inner side of the grinding wheel 12 will be inserted into the arc-shaped groove. Then, with the help of the grinding wheel pad 11 and the locking block 3, the grinding wheel 12 is fixed from both sides to ensure the stability of the grinding wheel 12 and provide convenience for the user's work.
