[0026] Furthermore, if Figure 2 and Figure 3 As shown, the surface of the fuse barrel body 1 is provided with a rapid heat dissipation mechanism 2, the interior of the rapid heat dissipation mechanism 2 includes a heat conducting plate 201, a heat dissipation through hole 202 and a rapid heat dissipation portion 203, the rapid heat dissipation portion 203 is provided on the surface of the fuse barrel body 1, the rapid heat dissipation portion 203 is composed of a heat dissipation fin 2031, a positioning card 2032 and a heat dissipation dustproof frame 2033, the surfaces of both sides of the fuse barrel body 1 are installed with a heat dissipation dustproof frame 2033, and the interior of the heat dissipation dustproof frame 2033 is installed with a heat dissipation fin 2031, a positioning card 2032 and a heat dissipation dustproof frame 2033 by screws.

Subsequently, when the heat inside the fuse tube body 1 is too high, the heat inside the fuse tube body 1 is dissipated by the action of the heat conduction plate 201, so that the heat enters the heat dissipation dustproof frame 2033 through the heat dissipation through hole 202, and the inside of the fuse tube body 1 is heat-dissipated by the action of the heat dissipation fin 2031. Since the structure of the heat dissipation dustproof frame 2033 is a mesh structure, the heat inside the heat dissipation dustproof frame 2033 can be discharged from the inside of the fuse tube body 1 through the heat dissipation dustproof frame 2033, so as to realize the function of rapid heat dissipation of the fuse tube.

[0028] Furthermore, if Figure 2 and Figure 4 As shown, the inner wall of the fuse tube body 1 is provided with an insulating anti-deformation mechanism 3, the interior of the insulating anti-deformation mechanism 3 includes an insulating layer 301, a fixed cavity 302, an anti-deformation plate 303 and an unsaturated polyester glass fiber layer 304, the interior of the fuse tube body 1 is provided with a fixed cavity 302, the fixed cavity 302 is provided with an unsaturated polyester glass fiber layer 304, the surface of the unsaturated polyester glass fiber layer 304 is bonded to the inner wall of the anti-deformation plate 303, the interior of the fixed cavity 302 is provided with an insulating layer 301, the surface of the insulating layer 301 is bonded to the inner wall of the fixed cavity 302, the interior of the fixed cavity 302 is provided with an anti-deformation plate 303, the surfaces of the anti-deformation plate 303 are respectively bonded to the surfaces of the insulating layer 301 and the unsaturated polyester glass fiber layer 304.

[0029] During implementation, the insulation effect of the fuse tube body 1 is better due to the action of the insulating layer 301 inside the fixed cavity 302, and the overall strength of the fuse tube body 1 is higher due to the joint action of the anti-deformation plate 303 and the unsaturated polyester glass fiber layer 304, thereby increasing the overall strength of the fuse tube body 1 during use, avoiding deformation and damage of the fuse tube body 1 during use, and realizing the insulation and anti-deformation function of the fuse tube.

The anti-dropping pad 4031 and the inner wall of the fixed frame 401 slide with each other. The inner wall of the fixed frame 401 is installed with sealing airbags 4033 at equal intervals. The surface of the sealing airbags 4033 is bonded to the surface of the anti-dropping pad 4031. The inner wall of the fixed frame 401 is installed with extension springs 4032 at equal intervals. One end of the extension spring 4032 is fixed to the surface of the anti-dropping pad 4031.

[0031] During implementation, the fuse tube body 1 is installed on the surface of the mounting frame 101 under the threaded cooperation of the fuse tube body 1 and the mounting frame 101. At this time, the anti-dropping pad 4031 and the sealing pad 402 are driven to move by the joint action of the sealing airbag 4033 and the extension spring 4032 inside the fixed frame 401, so that the anti-dropping pad 4031 drives the sealing pad 402 to move to contact the surface of the fuse tube body 1. Under the joint action of the anti-dropping pad 4031 and the sealing pad 402, the fuse tube body 1 can be more stably installed on the surface of the mounting frame 101, avoiding the phenomenon of the fuse tube body 1 becoming loose during use, so as to realize the function of facilitating the installation of the fuse tube.

[0032] Working principle: When in use, first place the fuse tube body 1 on the surface of the mounting frame 101, and the user rotates the fuse tube body 1, and installs the fuse tube body 1 on the surface of the mounting frame 101 under the threaded cooperation of the fuse tube body 1 and the mounting frame 101.

[0033] Subsequently, the installation position of the heat dissipation fin 2031 is positioned under the action of the positioning card 2032, and the heat dissipation fin 2031 is installed inside the heat dissipation dustproof frame 2033 under the action of the screw. Subsequently, when the heat inside the fuse tube body 1 is too high, the heat inside the fuse tube body 1 is discharged under the action of the heat conduction plate 201, so that the heat enters the heat dissipation dustproof frame 2033 through the heat dissipation through hole 202, and the inside of the fuse tube body 1 is dissipated under the action of the heat dissipation fin 2031. Since the structure of the heat dissipation dustproof frame 2033 is a mesh structure, the heat inside the heat dissipation dustproof frame 2033 can be discharged from the inside of the fuse tube body 1 through the heat dissipation dustproof frame 2033, so as to realize the function of rapid heat dissipation of the fuse tube, so that the inside of the fuse tube body 1 can be directly dissipated when the fuse tube is in use, and the heat dissipation efficiency is higher, thereby ensuring the overall safety of the fuse tube body 1 when in use.

[0034] Subsequently, under the action of the insulating layer 301 inside the fixed cavity 302, the insulation effect of the fuse tube body 1 is better, and under the joint action of the anti-deformation plate 303 and the unsaturated polyester glass fiber layer 304, the overall strength of the fuse tube body 1 is higher, which increases the overall strength of the fuse tube body 1 during use, and avoids the fuse tube body 1 from being deformed and damaged during use, so as to realize the insulation and anti-deformation function of the fuse tube, thereby making the insulation effect of the fuse tube better during use, avoiding the deformation of the fuse tube during use, greatly extending the service life of the fuse tube, and finally completing the use of the fuse tube.

[0035] It is obvious to those skilled in the art that the present invention is not limited to the details of the above exemplary embodiments, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention.
