[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] Reference Figure 1-Figure 2 , The utility model provides an embodiment: a welding machine protection device that is easy to load and unload, including a base 18, a welding machine body 1 is fixedly connected to the top of the base 18, a connecting block 2 is fixedly connected to the top of the welding machine body 1, a card slot 3 is opened inside the connecting block 2, a protective door 5 is arranged on one side of the welding machine body 1, and a connecting plate 4 is rotatably connected to the top of the protective door 5, a connecting column 6 is fixedly connected to one side of the connecting plate 4, and a card block 11 is rotatably connected to the connecting column 6. A connecting rod 10 is rotatably connected to one end of the connecting rod 10. The outer wall of the limiting plate 7 is slidably connected to the inside of the connecting column 6, and a supporting assembly is arranged inside the connecting column 6. The supporting assembly includes a telescopic rod 8 and a spring 9, and the spring 9 is sleeved on the outer wall of the telescopic rod 8. One end of the telescopic rod 8 and the spring 9 is fixedly connected to one side of the connecting plate 4, and the other end of the telescopic rod 8 and the spring 9 is fixedly connected to one side of the limiting plate 7. The outer wall of the connecting column 6 is slidably connected to the inside of the connecting block 2, and the outer wall of the card block 11 is embedded in the card slot 3;

[0028] Specifically, when the protective door 5 needs to be disassembled, the operation process is very simple. It is only necessary to separate the connecting column 6 from the connecting block 2 together with the protective door 5 and the connecting plate 4. In this process, the connecting column 6 is locked by embedding the internal card block 11 into the card slot 3 to ensure stable connection. It is worth mentioning that the design of the card block 11 is ingenious. Both sides of it are inclined, making the disassembly process easier. Just pull it out gently to separate the connecting column 6 from the connecting block 2. This design makes the disassembly of the protective door 5 simple and quick, greatly improving the efficiency of repair and maintenance. Inside the connecting column 6, the other side of the card block 11 is connected to the limit plate 7 through the connecting rod 10. This design allows the connecting column 6 to rotate internally during the disassembly process, ensuring the smooth separation of the card block 11 from the card slot 3. At the same time, the limit plate 7 is connected to the card block 11 through the connecting rod 10, so that the card block 11 is more stable when embedded in the card slot 3 and is not easy to slide out. In the entire disassembly process, the spring 9 plays a key supporting role. It supports the limiting plate 7 through tension to ensure that its position inside the connecting column 6 is stable. This design makes the disassembly process of the protective door 5 smoother and also improves the overall safety of the protective door 5.

[0029] Reference Figure 3 A fan 12 is fixedly connected inside the welding machine body 1, a heat dissipation port 13 is provided inside the welding machine body 1, a limit groove 14 is symmetrically arranged on the top of the welding machine body 1, a frame 15 is provided on the top of the welding machine body 1, the outer wall of the frame 15 is slidably connected inside the limit groove 14, a dustproof net 16 is fixedly connected inside the frame 15, and a handle 17 is fixedly connected to one side of the frame 15;

[0030] Specifically, during the operation of the welding machine body 1, heat dissipation is a crucial link. In order to ensure the safe and stable operation of the welding machine body 1, the welding machine body 1 can effectively inhale external air through the fan 12 when working, so as to take away the heat generated inside the welding machine body 1. After the fan 12 inhales the external air into the welding machine body 1, the air will circulate inside the welding machine to take away the heat. Subsequently, the heat will be discharged through the heat dissipation port 13 to ensure that the temperature inside the welding machine remains within an appropriate range. In this way, not only the normal operation of the welding machine is guaranteed, but also the risk of overheating of the equipment is reduced. During the welding process, a certain amount of smoke will be generated. In order to prevent the smoke from causing harm to external operators, we designed a dust net 16. After the smoke is filtered by the dust net 16, the pollutants will be effectively removed, thereby ensuring the safety of the operator. When the service life of the dust net 16 expires and needs to be replaced, the operator only needs to hold the handle 17 and pull out the frame 15 to easily replace the dust net 16.

[0031] Working principle: When using the welding machine protection device that is easy to load and unload, when the protection door 5 needs to be removed first, just directly separate the protection door 5 together with the connecting plate 4 to directly separate the connecting column 6 from the connecting block 2. The connecting column 6 is locked by embedding the internal card block 11 into the card slot 3. Since both sides of the card block 11 are inclined surfaces, it only needs to be pulled out for disassembly. One side of the card block 11 rotates inside the connecting column 6, and the other side of the card block 11 is limited inside the connecting column 6 through the connecting rod 10 and the limiting plate 7. Then, the limiting plate 7 is supported by the tension of the spring 9. , and then the limit plate 7 is connected to the block 11 through the connecting rod 10 so that the block 11 is not easy to slide out when it is embedded in the card slot 3. Then, when the welding machine needs to dissipate heat during work, the fan 12 draws external air into the welding machine body 1, and takes away the heat generated when the welding machine body 1 is working through the air, and then discharges it through the heat dissipation port 13. The smoke generated during welding is filtered and discharged through the dustproof net 16, and thus will not cause harm to external operators. When the dustproof net 16 needs to be replaced, only the frame 15 needs to be pulled out through the handle 17 to replace the dustproof net 16.

[0032] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
