A mounting box is fixedly connected to the front, back, and bottom surfaces of the box body. A sliding block is slidably connected to the inner wall of the mounting box. A first spring is fixedly connected to the bottom surface of the sliding block. The bottom end of the first spring is fixedly connected to the inner bottom wall of the box body. An L-shaped connecting block is fixedly connected to the side of the sliding block. The side of the L-shaped connecting block is curved. The mounting block is fixedly connected to the front, back, and bottom surfaces of the box body. The mounting block and the mounting box are respectively located on opposite sides of the box body.

[0023] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0024] like Figure 1 - Figure 4 As shown, a fire-resistant cable trough box includes a flame-retardant shell 1, an installation mechanism 2 and a connecting mechanism 3, the installation mechanism 2 is threadedly connected to the inner side of the flame-retardant shell 1, the connecting mechanism 3 is slidably connected to the inner side of the flame-retardant shell 1, the connecting mechanism 3 includes a sealing shell 306 slidably connected to the inner side of the flame-retardant shell 1, the outer surface of the sealing shell 306 is provided with a limiting groove, the outer surface of the sealing shell 306 is slidably connected to the limiting protrusion 302, and one end of the sealing shell 306 is provided with a sealing groove 303. The invention comprises a flame-retardant shell 1, an installation mechanism 2 and a connecting mechanism 3, the installation mechanism 2 is threadedly connected to the inner side of the flame-retardant shell 1, the connecting mechanism 3 is slidably connected to the inner side of the flame-retardant shell 1, the connecting mechanism 3 includes a sealing shell 306 slidably connected to the inner side of the flame-retardant shell 1, the outer surface of the sealing shell 306 is provided with a limiting groove, the outer surface of the sealing shell 306 is slidably connected to the limiting protrusion 302, and one end of the sealing shell 306 is provided with a sealing groove 303.

[0025] In order to assemble the cable trough box, the other end of the sealing shell 306 is fixedly connected to the sealing protrusion 304, and the outer surface of the sealing protrusion 304 is slidably connected to the inner side of the sealing groove 303. The sealing grooves 303 and the sealing protrusions 304 are respectively provided at both ends of the sealing shell 306, which facilitates the connection of two adjacent groups of sealing shells 306 together, thereby improving the sealing between the flame retardant shell 1 and the sealing shell 306. The connecting mechanism 3 also includes a limiting protrusion 302 fixedly connected to the inner wall of the flame retardant shell 1, and the outer surface of the limiting protrusion 302 is slidably connected to the limiting groove provided on the outer surface of the sealing shell 306. The limiting protrusion 302 facilitates the sealing of the sealing shell. The body 306 is limited to prevent the sealed shell 306 and the flame retardant shell 1 from separating. A slide groove 305 is provided at one end of the flame retardant shell 1, and the other end of the flame retardant shell 1 is fixedly connected to the connecting rod 301. The outer surface of the connecting rod 301 is slidably connected to the inner side of the slide groove 305. By sliding the connecting rod 301 into the slide groove 305, the two groups of flame retardant shells 1 are connected together by plugging. The connecting rod 301 adopts a convex structure, and the connecting rod 301 and the sealed shell 306 both adopt an injection molded integrated molding structure. By sliding the connecting rod 301 into the slide groove 305, it is convenient to prevent the two adjacent groups of flame retardant shells 1 from separating.

[0026] It is worth mentioning that sliding the connecting rod 301 into the slide groove 305 facilitates connecting the two adjacent groups of flame retardant shells 1 together. After the cable is laid, the sealing shell 306 is slid into the inner side of the flame retardant shell 1, so that the outer surface of the sealing shell 306 slides along the outer surface of the limiting protrusion 302. The limiting protrusion 302 facilitates the limiting of the sealing shell 306, and the sealing protrusion 304 slides into the sealing groove 303, thereby facilitating the increase of the sealing between the flame retardant shell 1 and the sealing shell 306, facilitating the assembly of the flame retardant shell 1 and the sealing shell 306, thereby improving the assembly efficiency, and the flame retardant shell 1 and the sealing shell 306 facilitate the outer surface of the cable to be covered, thereby increasing the protection of the cable.

[0027] In order to fix the cable trough box, the installation mechanism 2 includes a bolt 203 threadedly connected to the inner side of the flame retardant shell 1, and the outer surface of the bolt 203 is rotatably connected to a sealing gasket 204. The installation mechanism 2 also includes a fixed frame 202 fixedly connected to the inner side of the flame retardant shell 1, and the outer surface of the fixed frame 202 is fixedly connected to multiple groups of partition flame retardant plates 201. The multiple groups of partition flame retardant plates 201 are convenient for separating cables and protecting cables.

[0028] It is worth mentioning that by rotating the bolt 203 so that the bolt 203 is fixed to the wall, the outer surface of the bolt 203 presses the outer surface of the sealing gasket 204, which facilitates the installation and fixation of the flame retardant shell 1 and increases the stability of the flame retardant shell 1.

[0029] Working principle: Slide the connecting rod 301 into the slide groove 305 to connect the two adjacent groups of flame retardant shells 1 together, and then fix the bolt 203 to the wall by rotating the bolt 203. The outer surface of the bolt 203 squeezes the outer surface of the sealing gasket 204 to facilitate the installation of the flame retardant shell 1. Then lay the cable between the partition flame retardant plates 201, and then slide the sealing shell 306 into the inner side of the flame retardant shell 1, so that the outer surface of the sealing shell 306 slides along the outer surface of the limiting protrusion 302. The limiting protrusion 302 is used to limit the sealing shell 306, and the sealing protrusion 304 slides into the sealing groove 303, thereby facilitating the increase of the sealing between the flame retardant shell 1 and the sealing shell 306. The flame retardant shell 1 and the sealing shell 306 are used to cover the outer surface of the cable, thereby increasing the protection of the cable.
