[0029] The following is combined with Figure 1-6 , the specific implementation methods of the utility model are further described in detail to make the technical solution of the utility model easier to understand and grasp.

[0030] In this embodiment, it should be understood that the terms "middle", "upper", "lower", "top", "right side", "end", "front", "back", "middle", etc. indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0031] In addition, in this specific embodiment, if the connection or fixing method between components is not specifically described, the connection or fixing method can be through bolt fixing or pin fixing, or pin shaft connection and the like commonly used in the prior art, and therefore, it is not described in detail in this embodiment.

[0032] The following is combined with Figure 1-6 This application is described in further detail.

[0033] like Figure 2 , Figure 3 and Figure 5 As shown, a fireproof pipe comprises:

[0034] A pipe body 1, the pipe body 1 includes a plurality of mounting components 11 and a plurality of plates 12 assembled with the mounting components 11, the mounting components 11 include a first mounting member 111 and a second mounting member 112, the first mounting member 111 and the second mounting member 112 are abutted against each other to form a first mounting portion 113 and a second mounting portion 114, the plates 12 are assembled with the first mounting portion 113 and the second mounting portion 114 respectively, of course, in order to better fix the plates 12, after the plates 12 are assembled in the mounting components 11, the stability between the mounting components 11 and the plates 12 can be reinforced by bolt connection. In this embodiment, the mounting components 11 are arranged in a "jin" shape, and the mounting components 11 are integrally formed. In other embodiments, the mounting components 11 are welded. By splitting the pipe body 1, the volume becomes smaller, which is convenient for the staff to move and transport, and also reduces a certain amount of floor space, so that the staff can perform installation operations on site.

[0035] A first protective layer (not shown) is disposed on the surface of the mounting component 11 . The first protective layer is an anti-corrosion layer to prevent the mounting component 11 from being corroded, thereby increasing the service life of the mounting component 11 .

[0036] like Figure 1 and Figure 6 As shown, it also includes a shock absorbing device 2, which is assembled with the tube body 1. The shock absorbing device 2 includes a frame 21 and a box 22. The frame 21 and the box 22 are connected by a connecting block 23, and the connecting block 23 can move relative to the box 22.

[0037] A cylinder 24 and a fixing member 25 are arranged in the box 22. The fixing member 25 is arranged in an I-shaped configuration, which can better cooperate with the cylinder 24 to prevent the fixing member 25 from falling out of the cylinder 24. One end of the fixing member 25 is assembled with the top of the box 22, and the other end is assembled with the cylinder 24. The cylinder 24 is assembled with the connecting block 23, and a spring 26 is arranged in the cylinder 24. When the pipe 1 vibrates, the vibration is transmitted to the connecting block 23 through the frame 21, and then the connecting block 23 transmits the vibration to the cylinder 24. When the cylinder 24 moves upward, the spring 26 buffers the transmitted vibration, reduces the vibration of the pipe 1, and effectively reduces the noise generated by the pipe 1.

[0038] A connecting rod 27 is provided on both sides of the cylinder 24, and a slider 28 is provided on the connecting rod 27. A slide rail 20 cooperating with the slider 28 is provided on both sides of the inner wall of the box body 22, which provides a certain support effect for the cylinder 24 and makes the cylinder 24 move more smoothly; a protrusion 29 is provided on both sides of the inner wall of the box body 22 to cooperate with the slider 28 to prevent the slider 28 from sliding out of the slide rail 20.

[0039] The top of the frame 21 and the bottom of the box 22 are opened, and the frame 21 has a certain elasticity, so that the staff can pull the frame 21 to frame the tube 1, which is convenient and quick.

[0040] A flange 3 is respectively provided at the front and rear ends of the pipe body 1, and the flange 3 is covered on the mounting assembly 11, which can better fix the plate 12 in the mounting assembly 11 to avoid looseness and affect the working effect. In this embodiment, the flange 3 is a galvanized angle steel flange 3, which has a flange 3 plate with good corrosion resistance. Through galvanizing treatment, a zinc layer is attached to the surface of the flange 3, thereby achieving the purpose of corrosion protection.

[0041] like Figure 4As shown, the plate 12 includes a fireproof layer 121, and at least one second protective layer 122 is provided on the surface of the fireproof layer 121. In the present embodiment, the thickness of the fireproof layer 121 is more than 40 mm, and the fireproof layer 121 is rock wool, so that the pipe body 1 has sufficient fire resistance. There are two second protective layers 122, which are respectively arranged at the upper end and the lower end of the fireproof layer 121. The second protective layer 122 is used to protect the fireproof layer 121 to prevent the fireproof layer 121 from being damaged, and the second protective layer 122 is galvanized steel plate, which has good corrosion resistance, high cleanliness, and wide adaptability. In other embodiments, the fireproof layer 121 can also be aluminum silicate wool or fire-resistant glass wool, which will not be described in detail here. Since the plate 12 has its own fireproof layer 121, there is no need for fireproof treatment, which saves manufacturing time. Compared with the existing process of wrapping the air duct body with rock wool and a fireproof board, a galvanized steel plate (i.e., the second protective layer 122) is directly provided on the surface of the fireproof layer 121, thereby avoiding problems such as bulging, deformation and cracking caused by moisture absorption of the fireproof board, and at the same time reducing the weight, effectively reducing the load on the building and saving construction costs.

[0042] The technical effects of this utility model are mainly reflected in the following aspects:

[0043] The fireproof pipe is convenient for transportation and installation by workers.

[0044] Of course, the above are only typical examples of the present invention. In addition, the present invention may have many other specific implementations. Any technical solutions formed by equivalent replacement or equivalent transformation fall within the scope of protection required by the present invention.
