[0023] The utility model will be further described below in combination with embodiments.

[0024] Embodiment 1:

[0025] Please refer to Figures 2-5The fire blocking assembly 4 comprises an outer ring 41, a fire blocking plate 42 fixedly connected inside the outer ring 41, a connecting block 44 fixedly connected to the inner wall of the second shell 3, a first spring 45 fixedly connected to one side of the connecting block 44, and a fire blocking plate 46 fixedly connected to one end of the first spring 45. The outer ring 41 and the fire blocking plate 42 are each provided in multiple groups. A second spring 43 is fixedly connected between every two groups of the outer ring 41. The fire blocking plate 46 is arranged inside the second shell 3. The fire blocking plate 42 serves as a part directly contacting the flame, facilitating the rapid absorption of heat, reducing the temperature of the flame, and preventing the flame from continuing to spread. The multiple groups of the fire blocking plate 42 provide multiple fire blocking barriers. Even if a certain layer of the fire blocking plate 42 fails, the subsequent fire blocking plate 42 can still continue to function, greatly improving the overall fire blocking effect. The second spring 43 connected between every two groups of the outer ring 41 provides additional buffering force, so that the fire blocking plate 42 can still maintain the integrity of the structure and the effectiveness of the function when subjected to strong impact. Through the action of the first spring 45, the fire blocking plate 46 facilitates further blocking of the flame and hot gas flow, thereby increasing the fire blocking effect.

[0026] The first positive screw groove 13 and the second positive screw groove 14 are respectively formed in the inner wall of the mounting ring 1. The mounting ring 1 is provided with a limiting ring 5. The limiting ring 5 comprises a first connecting ring 51 and a second connecting ring 52 fixedly connected to one end of the first connecting ring 51. A reverse screw groove 521 is formed in the outer surface of the second connecting ring 52. The limiting ring 5 is provided with two groups of reverse screw grooves 521. One group of the reverse screw grooves 521 is correspondingly arranged with the first positive screw groove 13, and the other group of the reverse screw grooves 521 is correspondingly arranged with the second positive screw groove 14. Through the corresponding arrangement of the two groups of reverse screw grooves 521 and the first positive screw groove 13 and the second positive screw groove 14, the two groups of limiting rings 5 can be easily screwed into the two ends of the mounting ring 1, so as to facilitate the fixation of the fire blocking plate 42 inside the mounting ring 1. The fire blocking plate 42 can be taken out by unscrewing the limiting ring 5, which is easy to disassemble and maintain.

[0027] The fire blocking plate 42 is in contact with one end of the second connecting ring 52. The first connecting ring 51 extends out of the mounting ring 1, which facilitates the rotation of the first connecting ring 51. The rotation of the first connecting ring 51 drives the rotation of the second connecting ring 52, thereby facilitating the removal of the second connecting ring 52.

[0028] A first screw hole 11 is formed in one end of the mounting ring 1, and a second screw hole 12 is formed in the other end of the mounting ring 1.

The first connecting hole 221 is formed in the outer surface of the first flange 22, and the second connecting hole 322 is formed in the outer surface of the second flange 32. The first flange 22 and the second flange 32 are fixed to the outside through the first connecting hole 221 in the outer surface of the first flange 22 and the second connecting hole 322 in the outer surface of the second flange 32.

[0030] The first flange 22 is fixedly connected to one end of the first shell 2, and the second flange 32 is fixedly connected to one end of the second shell 3. The first connecting hole 221 is formed in the outer surface of the first flange 22, and the second connecting hole 322 is formed in the outer surface of the second flange 32. The first flange 22 and the second flange 32 are fixed to the outside through the first connecting hole 221 in the outer surface of the first flange 22 and the second connecting hole 322 in the outer surface of the second flange 32.

[0031] In use, the two groups of limiting rings 5 are screwed into the two ends of the mounting ring 1 through the corresponding arrangement of the two groups of reverse threaded grooves 521 and the first and second forward threaded grooves 13 and 14, so as to fix the fire barrier plate 42 inside the mounting ring 1. The mounting ring 1 is fixed between the first shell 2 and the second shell 3 under the action of the first and second locking bolts 21 and 31. The first flange 22 and the second flange 32 are fixed to the outside through the first connecting hole 221 in the outer surface of the first flange 22 and the second connecting hole 322 in the outer surface of the second flange 32. The fire barrier plate 42, as the part directly contacting the flame, can quickly absorb heat, reduce the temperature of the flame, and prevent the flame from continuing to spread. Multiple fire barrier plates 42 provide multiple fire barriers. Even if one layer of fire barrier plate 42 fails, the subsequent fire barrier plate 42 can still function, greatly improving the overall fire resistance effect. The second spring 43 connected between each outer ring 41 provides additional buffering force, so that the fire barrier plate 42 can maintain the integrity of the structure and the effectiveness of the function when subjected to strong impact. The fire barrier plate 46 is further used to block the flame and hot gas flow under the action of the first spring 45, so as to increase the fire resistance effect.
