Fuses are widely used in high and low voltage power distribution systems, control systems, and electrical equipment as short-circuit and overcurrent protectors, and are one of the most commonly used protective devices.
[0003] Existing portable fuses require a mounting bracket for installation. Publication number CN218849410U discloses a fuse fixing structure, including: a first fixing plate, a second fixing plate, a mounting part, a first assembly part, and a second assembly part. The first and second fixing plates are arranged parallel to each other, with a cavity between them suitable for placing the fuse. The two ends of the first and second fixing plates are connected by a connecting part, wherein the connecting part has a connecting hole suitable for connecting the fuse. The mounting part is fixedly mounted on the fixing structure and is suitable for mounting on a housing. At least one first assembly part is provided on the first fixing plate, and a second assembly part is fixedly provided on the second fixing plate corresponding to the first assembly part. The first assembly part and the second assembly part are detachably connected. This device can fix multiple fuses by splicing, thereby simplifying the installation process. However, when using this device, the mounting holes of the fuses are fixed and cannot be fine-tuned. If the fuses and the mounting holes on the mounting bracket do not match well, it will be difficult to install and require more operation time. Therefore, a convenient fuse that can be finely adjusted is needed. Utility Model Content

[0025] Please see Figure 1-4 This utility model provides a technical solution: a convenient fuse, including a fuse assembly component 1 and a mounting hole fine-tuning mechanism. The mounting hole fine-tuning mechanism includes an adjusting block 11, a threaded rod 15, a rotating part 16, a slider 17, a first connecting member 18, a connecting rod 19, and a second connecting member 20. There are two adjusting blocks 11, both of which are slidably connected inside the fuse assembly component 1. The threaded rod 15 is rotatably connected inside the fuse assembly component 1. The rotating part 16 is fixedly connected to the bottom of the threaded rod 15. The slider 17 is threadedly sleeved on the outer surface of the threaded rod 15. The first connecting member 18 is fixedly connected to the surface of the slider 17. There are multiple connecting rods 19, all of which are rotatably connected to the surface of the first connecting member 18. There are multiple second connecting members 20, all of which are fixedly connected to the bottom of the corresponding adjusting block 11. Each second connecting member 20 is rotatably connected to the connecting rod 19.
[0026] Furthermore, the inner wall of the fuse assembly component 1 is provided with a limiting groove 12 to limit the sliding of the adjusting block 11. The top of the adjusting block 11 is provided with a second mounting hole 9 for fixing the fuse. The interior of the fuse assembly component 1 is provided with two rectangular grooves 13, and the adjusting block 11 is slidably connected to the rectangular grooves 13. The interior of the fuse assembly component 1 is provided with a receiving groove 14. The surface of the fuse assembly component 1 is bolted with mounting bolts 3. The surface of the fuse assembly component 1 is provided with mounting screw holes 4 that are adapted to the mounting bolts 3. The interior of the fuse assembly component 1 is threaded with a mounting component 7. The surface of the mounting component 7 is fixedly connected with a fuse body 10. The surface of the mounting component 7 is provided with a first mounting hole 8. The top of the fuse assembly component 1 is provided with a mounting groove 6 for mounting the fuse body 10. The surface of the fuse assembly component 1 is fixedly connected with multiple limiting strips 2. The surface of the fuse assembly component 1 is provided with multiple limiting grooves 5 that are adapted to the limiting strips 2.
[0027] Furthermore, during installation, the first mounting hole 8 on the mounting component 7 is aligned with the second mounting hole 9. The rotating part 16 at the bottom of the fuse assembly component 1 can be rotated. The bottom of the rotating part 16 has a screwdriver adapter hole for auxiliary rotation. Rotating the rotating part 16 drives the threaded rod 15 to rotate, which in turn drives the slider 17 to move on the outer surface of the threaded rod 15. Through the action of the connecting rod 19, the first connecting piece 18 and the second connecting piece 20 drive the two adjusting blocks 11 to move closer or further apart, thereby fine-tuning the distance between the two second mounting holes 9, making it easier to align the first mounting hole 8, which helps with installation and fixation. The limiting strip 2 and limiting groove 5 on the surface of the fuse assembly component 1 can realize the splicing between multiple fuse assembly components 1. Then, the fuse assembly components 1 on both sides can be fixed to the surface of the equipment with bolts.
[0028] Furthermore, the installation hole fine-tuning mechanism allows for adjustment of the distance between the two adjusting blocks 11, thereby changing the position between the two second installation holes 9. This helps to align the first installation hole 8 on the mounting component 7, facilitating the installation and fixing of the fuse body 10. This solves the problem that the fuse installation hole part cannot be fine-tuned, and that if the fuse and the mounting hole on the assembly frame have a low degree of compatibility, it is easy to cause installation difficulties and require more operation time.
