Technical Field

[0001] This utility model relates to the field of angle grinder protection technology, specifically an angle grinder protective cover structure. Background Technology

[0002] An angle grinder, also known as a grinding machine or disc grinder, is a primary tool for cutting and polishing. It can cut metal, stone, and other materials. When cutting, a protective cover is usually placed on the grinding disc to prevent waste from flying during grinding and, more importantly, to prevent the grinding disc from breaking during grinding and causing personal injury.

[0003] The existing angle grinder's protective cover is installed near the grinding disc and is connected to the main body of the equipment using a double fixing method of clips and screws. This protective device is prone to wear and breakage due to the impact and debris generated during long-term contact with the machine, and needs to be replaced regularly to eliminate safety hazards. However, the traditional screw-locking structure involves tool operation and thread alignment during disassembly and assembly, which makes the replacement process complicated and time-consuming, and may affect maintenance efficiency.

[0004] Therefore, this utility model provides an angle grinder cover structure to solve the above problems. Utility Model Content

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0026] This utility model provides an angle grinder guard structure, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, the angle grinder guard structure includes an angle grinder body 1, an angle grinder head 2 fixedly mounted on the angle grinder body 1, a grinding disc 3 rotatably mounted on the angle grinder head 2, a mounting cover 4 disposed on the angle grinder head 2, a first protective cover 5 fixedly mounted on the mounting cover 4, a limiting chamber 7 opened inside the angle grinder head 2, and a replacement mechanism disposed inside the limiting chamber 7 for quickly replacing the first protective cover 5.

[0027] The replacement mechanism includes a pin 6 fixedly installed inside the mounting cover 4, a sleeve 8 fixedly installed inside the limiting chamber 7, a mounting block 9 fixedly installed on the inner wall of the limiting chamber 7, a telescopic rod 10 fixedly installed on the mounting block 9, a first spring 11 sleeved on the telescopic rod 10, a pin 12 fixedly installed on the movable end of the telescopic rod 10, a pressing block 13 slidably installed inside the limiting chamber 7, and multiple inclined strips 14 fixedly installed at the bottom of the pressing block 13.

[0028] One end of the first spring 11 is fixedly connected to one side of the mounting block 9, and the other end of the first spring 11 is fixedly connected to one side of the insert block 12. The insert block 12 passes through the sleeve 8. The side surface of the insert post 6 is provided with a slot for the insert block 12 to be inserted into. The inclined surface of the inclined bar 14 is in contact with the inclined surface of the insert block 12.

[0029] When using this angle grinder guard structure, first align the insert 6 on the mounting cover 4 with the limiting chamber 7 and insert it inside. The insert 6 will initially contact the inclined surfaces of the two insert blocks 12. As the insert 6 continues to move downwards, it will push the two insert blocks 12 outwards, thereby compressing the first spring 11. At the same time, the telescopic rod 10 retracts until the slot of the insert 6 moves until the insert blocks 12 are on the same horizontal line. The elastic potential energy of the first spring 11 pushes the two insert blocks 12 into the slot, completing the limiting of the insert 6 and thus completing the installation of the first protective cover 5. Afterwards, start the angle grinder body 1 and turn on the power supply. The grinding disc 3 begins to rotate and grind. When it is necessary to replace the first protective cover 5, the pressing block 13 is manually pressed downwards. The pressing block 13 drives multiple inclined strips 14 to move downwards synchronously. As the inclined strips 14 move downwards and their inclined surfaces come into contact with the inclined surfaces of the insert blocks 12, the two insert blocks 12 are pressed outwards until the insert blocks 12 are removed from the inside of the slot, stopping the restriction on the insert post 6. At this time, the mounting cover 4 and the first protective cover 5 can be removed. The above operation is repeated to achieve quick replacement of the mounting cover 4 and the first protective cover 5. The replacement process is simple and time-saving, improving maintenance efficiency.

[0030] Furthermore, in order to reset the pressing block 13 and the inclined strip 14 after the first protective cover 5 has been removed, as follows: Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, a pad 15 is slidably connected to the side surface of the sleeve 8, and a second spring 16 is sleeved on the side surface of the sleeve 8. One end of the second spring 16 is fixedly connected to the bottom of the limiting chamber 7, and the other end of the second spring 16 is fixedly connected to the bottom of the pad 15. The bottom of the inclined strip 14 is in contact with the top of the pad 15.

[0031] When using this angle grinder cover structure, the pressing block 13 is manually pressed downwards, causing multiple inclined bars 14 to move downwards synchronously, eventually removing the mounting cover 4 and the first protective cover 5. While pressing the pressing block 13, the inclined bars 14 move downwards to press the pad 15, and simultaneously press the second spring 16. After the mounting cover 4 is removed, the elastic potential energy of the second spring 16 presses the pad 15 upwards, and the pad 15 drives the pressing block 13 to return to its initial position, preparing for the next operation.

[0032] In order to protect the grinding disc 3 when the angle grinder body 1 is not in use, such as Figure 1 , Figure 2 and Figure 5 As shown, the inside of the first protective cover 5 is provided with a curved groove 17, and a slider 19 is slidably connected inside the curved groove 17.

[0033] The bottom of the slider 19 is fixedly connected to a second protective cover 18, and the top of the second protective cover 18 is in contact with the bottom of the first protective cover 5.

[0034] When the angle grinder body 1 is not in use and needs to be placed, the slider 19 is manually rotated along the curved groove 17. The movement of the slider 19 drives the second protective cover 18 to move synchronously along the curved groove 17, so that the second protective cover 18 and the first protective cover 5 can protect the grinding disc 3.

[0035] Furthermore, for ease of use of the angle grinder body 1, such as Figure 1 , Figure 2 and Figure 6 As shown, threaded holes 20 are provided on both sides of the angle grinder body 1, and handles 21 are screwed into the inside of the threaded holes 20.

[0036] When using this angle grinder cover structure, the handle 21 is aligned with the threaded hole 20, and the handle 21 is rotated to install the handle 21 on the angle grinder body 1. The angle grinder body 1 has threaded holes 20 on both sides, so the handle 21 can be installed on both sides of the angle grinder body 1 to accommodate different user habits. Then, the grinding disc 3 can be better controlled for grinding through the handle 21.

[0037] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
