[0027] For ease of understanding, the following refers to the attached Figures 1 to 2 drawings and describes in detail the specific structure and working principle of the fuse installation device of the present disclosure in combination with embodiments.
[0028] The present disclosure relates to a fuse installation device. Referring to Figure 1 and Figure 2 , the fuse installation device includes a bracket 1 and an abutting rod 2. The bracket 1 is the main body of the fuse installation device, which can provide an installation space for other components. The bracket 1 can be made of metal materials. On the one hand, it has good strength and is convenient for use. On the other hand, it has a long service life. A connecting hole 11 and a receiving groove 12 are provided on the bracket 1. The receiving groove 12 can place the fuse during the installation of the fuse to avoid interference between the fuse and the bracket 1. The abutting rod 2 is located in the connecting hole 11 and can move along the axial direction of the connecting hole 11. The abutting rod 2 further includes a first end and a second end, wherein the second end is located in the receiving groove 12 and can abut the bracket 1 against the fuse during the installation of the fuse to prevent the fuse from moving during the installation process.
[0029] Specifically, when installing the fuse, taking the installation on the exciter as an example, the fuse can be first placed at the position to be installed, and then the bracket 1 is placed on the outer shell of the exciter, so that the fuse can be located in the receiving groove 12 of the bracket 1. Finally, the abutting rod 2 is moved so that the second end of the abutting rod 2 can abut against the fuse. Through the cooperation among the bracket 1, the abutting rod 2 and the outer shell of the exciter, the stability of the fuse at the position to be installed can be ensured, enabling the staff to perform subsequent installation operations and preventing the fuse from moving during the installation process.
[0030] The fuse installation device of the present disclosure can fix the fuse when installing the fuse, preventing the fuse from moving during the installation process, ultimately affecting the installation effect of the fuse and causing potential safety hazards. Moreover, the fuse installation device of the present disclosure has a simple structure, is convenient to carry and use, enabling ordinary staff to promptly perform maintenance, installation, replacement, etc. of the fuse without waiting for professional personnel.
[0031] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , the bracket 1 includes two first extension parts 13 and a second extension part 14 located between the two first extension parts 13. Among them, the two end parts of the second extension part 14 are respectively connected to the end parts on the same side of the two first extension parts 13, thus forming the bracket 1, and the receiving groove 12 is surrounded by the two first extension parts 13 and the second extension part 14. The extending direction of the first extension part 13 can be determined according to the shape of the equipment at the fuse installation position. For example, if the shape of the equipment is horizontally extended, in order to facilitate the cooperation with the equipment, the first extension part 13 can also be extended along the horizontal direction, and the extending directions of the two first extension parts 13 can also be different, which can be specifically determined according to the actual installation situation. The extending direction of the second extension part 14 is opposite to that of the first extension part 13, mainly for connecting the two first extension parts 13.
[0032] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , taking the installation of the fuse in the exciter as an example, in order to cooperate with the outer shell at the fuse installation position of the exciter, the first extension part 13 is set to be extended along the horizontal direction and arranged in parallel with each other, and the second extension part 14 is extended along the vertical direction for connecting the two first extension parts 13, making the bracket 1 in a U shape, thus facilitating the installation of the fuse on the exciter. Of course, in other embodiments, the shapes of the first extension part 13 and the second extension part 14 can also be of other types, which can be specifically determined according to the actual application scenarios and application equipment, and the present disclosure does not limit this.
[0033] In an embodiment of the present disclosure, refer to Figure 1 andFigure 2 , the connecting hole 11 is located at the end of one of the first extension parts 13 that is not connected to the second extension part 14. When installing the fuse, the first extension part 13 without the connecting hole 11 can abut against the fuse. For the first extension part 13 with the connecting hole 11, it is necessary to adjust the position of the abutting rod 2 in the connecting hole 11 so that the second end of the abutting rod 2 can tightly abut against the outer shell at the position where the device is to be installed, thereby enabling the bracket 1 to tightly abut against the fuse, preventing the fuse from moving during the installation process by the staff, and thus enabling the staff to smoothly install the fuse.
[0034] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , a flexible pad 131 is provided on the first extension part 13 without the connecting hole 11. The flexible pad 131 can be made of materials such as rubber and resin, that is, it has a certain elasticity and a certain hardness. The shape of the flexible pad 131 can be adapted to the shape of the first extension part 13. Refer to Figure 2 . In this embodiment, the shape of the first extension part 13 is rectangular. For the convenience of matching with the first extension part 13, the shape of the flexible pad 131 is also rectangular. Of course, in other embodiments, the flexible pad 131 can also be of other shapes, which will not be elaborated here too much. By providing the flexible pad 131, when the first extension part 13 abuts against the fuse, the side with the flexible pad 131 abuts against the fuse to play a certain buffering role, preventing the first extension part 13 from damaging the fuse.
[0035] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , weight-reducing grooves 15 are provided on the first extension part 13 and the second extension part 14. The shape of the weight-reducing grooves 15 can be determined according to the shapes of the first extension part 13 and the second extension part 14 to occupy a larger space on the first extension part 13 and the second extension part 14. By providing the weight-reducing grooves 15, the weight of the bracket 1 can be reduced, enabling the staff to more conveniently carry the fuse installation device for installing, overhauling, and replacing the fuse.
[0036] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2, the connecting hole 11 is a threaded hole, and an external thread capable of cooperating with the threaded hole is provided on the outer wall of the abutting rod 2. The cooperation between the connecting hole 11 and the abutting rod 2 is achieved by threading, which has good stability, avoids loosening of the abutting rod 2 when it does not need to move, and is also convenient for processing the connecting hole 11 and the abutting rod 2. When it is necessary to move the abutting rod 2 in the connecting hole 11, only need to rotate the abutting rod 2 clockwise or counterclockwise to make the abutting rod 2 move forward or backward in the connecting hole 11, so that the abutting rod 2 can press the bracket 1 tightly against the fuse. Of course, in other embodiments, the connecting hole 11 and the abutting rod 2 can also be snap-connected or movably fitted together in other ways known to those skilled in the art, and will not be elaborated here.
[0037] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , a matching portion 21 is provided on the first end of the abutting rod 2. Through the matching portion 21, it can cooperate with a power tool to drive the abutting rod 2 to rotate, so as to realize the movement of the abutting rod 2 relative to the connecting hole 11. The power tool can be a component that can provide power, such as manually provided by a worker, a motor, etc. Taking the power provided manually by a worker as an example, the matching portion 21 can be a connecting rod provided at the first end of the abutting rod 2. The connecting rod penetrates through the first end of the abutting rod 2. When it is necessary to drive the abutting rod 2 to rotate, the worker can hold the connecting rod and drive the abutting rod 2 to rotate. Compared with directly manually driving the abutting rod 2 to rotate, driving the abutting rod 2 to rotate through the connecting rod can be more labor-saving and is also more convenient for the operation of the worker.
[0038] In an embodiment of the present disclosure, refer to Figure 1 and Figure 2 , an arc surface is provided at the second end of the abutting rod 2. In this embodiment, refer to Figure 2 , the second end of the abutting rod 2 is hemispherical. By setting the second end of the abutting rod 2 as hemispherical, when the second end of the abutting rod 2 abuts against the outer shell of the device, it will not cause damage to the outer shell of the device. Of course, in other embodiments, other protective structures can also be provided at the second end of the abutting rod 2. For example, a flexible layer can be provided at the second end of the abutting rod 2. The present disclosure does not limit this.
[0039] The fuse installation device of the present disclosure can be used for the installation of fuses in an exciter. When installing, the fuse can be first placed at the position to be installed, and then the bracket 1 is placed at the position to be installed of the exciter fuse, so that the fuse can be located in the receiving groove 12 on the bracket 1. Then, a first extension 13 of the bracket 1 is abutted against the fuse. Finally, the abutting rod 2 is rotated through the engaging portion 21, so that the second end of the abutting rod 2 can be tightly abutted against the outer shell of the exciter, thereby driving the first extension 13 to be tightly abutted against the fuse. After the abutting is completed, the staff can continue with the subsequent fuse installation. Through the fuse installation device of the present disclosure, the fuse can be fixed during the installation process, ensuring the stability of the fuse during the installation process, avoiding the movement of the fuse during the installation process, affecting the installation effect, and ultimately bringing potential safety hazards. Moreover, the fuse installation device of the present disclosure has a simple structure, is easy to carry, and can also facilitate the staff to install, replace and repair the fuse in a timely manner.
