[0029] Reference Figure 1 -6. The utility model provides a multi-layer composite thermal insulation steel pipe, comprising:

[0030] The main unit 100 includes a steel pipe main body 101;

[0031] The installation unit 200 includes a first curved plate 201, which is arranged on the outside of the steel pipe body 101, and the second curved plate 202 is rotatably connected to the first curved plate 201. Rubber pads 203 are arranged on the inner sides of the first curved plate 201 and the second curved plate 202, and an air insulation layer 204 is arranged on the inner side of the rubber pad 203, and an aluminum box reflection layer 205 is arranged on the inner side of the air insulation layer 204. High-temperature resistant glass wool 206 is arranged on the inner side of the aluminum box reflection layer 205, and the high-temperature resistant glass wool 206 is fitted with the steel pipe body 101. Rectangular blocks 207 are symmetrically fixedly connected to the first curved plate 201, and fixed blocks 208 are symmetrically fixedly connected to the second curved plate 202. A limiting component 209 for limiting the second curved plate 202 is arranged in the middle of the rectangular block 207.

[0032] Among them, the limiting component 209 includes two sliding blocks 209a. Sliding grooves 209b are symmetrically formed in the middle of the two rectangular blocks 207. The two sliding blocks 209a are respectively slidably connected to the inner walls of the two sliding grooves 209b. A spring 209c is fixedly connected between the inner wall of the sliding groove 209b and the sliding block 209a. The front end of the sliding block 209a is fixedly connected with a connecting block 209d. The connecting block 209d slidably penetrates through the rectangular block 207. A latch 209e is fixedly connected to the outside of the connecting block 209d. A slot 209f that cooperates with the latch 209e is formed in the fixed block 208. During use, when the sliding block 209a slides, it drives the connecting block 209d, and the spring 209c is compressed. Subsequently, when the second arc-shaped plate 202 is flipped to fit with the first arc-shaped plate 201, the spring 209c rebounds, causing the sliding block 209a to drive the connecting block 209d, and the connecting block 209d drives the latch 209e to insert into the slot 209f on the fixed block 208, thereby completing the installation of the first arc-shaped plate 201 and the second arc-shaped plate 202.

[0033] Further, a handle 210 is fixedly connected to the upper end of the sliding block 209a. The handle 210 slidably penetrates through the rectangular block 207. Anti-slip patterns are provided on the handle 210. By providing the anti-slip patterns, it is convenient to generate friction between the handle 210 and the staff's hand, avoiding the phenomenon of hand slipping when the staff uses the handle 210.

[0034] Further, a limiting block 211 is slidably connected to the rectangular block 207. The limiting block 211 is in a "mountain" shape. By providing the limiting block 211, it is convenient for the limiting block 211 to limit the handle 210, facilitating the staff to install the first arc-shaped plate 201 and the second arc-shaped plate 202.

[0035] Further, T-shaped sliders 212 are symmetrically and fixedly connected to the lower end of the limiting block 211. T-shaped sliding grooves 213 that cooperate with the T-shaped sliders 212 are formed in the rectangular block 207. By providing the T-shaped sliders 212 and the T-shaped sliding grooves 213, it is convenient for the limiting block 211 to drive the T-shaped sliders 212 during movement, enabling the T-shaped sliders 212 to slide in the T-shaped sliding grooves 213 to limit the limiting block 211, facilitating to improve the stability of the limiting block 211 during movement.

[0036] Even further, a first magnet 214 is provided on the inner side of the upper end of the first arc-shaped plate 201, and a second magnet 215 is provided on the inner side of the upper end of the second arc-shaped plate 202. The first magnet 214 and the second magnet 215 attract each other. By providing the first magnet 214 and the second magnet 215, it is convenient for the first magnet 214 and the second magnet 215 to fixedly install the first arc-shaped plate 201 and the second arc-shaped plate 202 under the action of mutual attraction.

[0037] During use, the first curved plate 201 and the second curved plate 202 are installed to the outside of the steel pipe body 101, and then the handle 210 is pulled inward, and the handle 210 drives the sliding block 209a, so that the sliding block 209a drives the connecting block 209d, and the spring 209c is compressed. When the two handles 210 are close to the middle of the rectangular block 207, the limiting block 211 is pushed to the front end, so that the limiting block 211 drives the T-shaped sliding block 212 to slide in the T-shaped sliding groove 213, and the two handles 210 are respectively engaged with the two notches at the front end of the limiting block 211, and then, the handle 210 is released, so that the handle 210 drives the sliding block 209a, and the spring 209c rebounds. Under the constraint of the limiting block 211, the handle 210 is restricted, and then, the second curved plate 202 is turned over, so that the second curved plate 202 simultaneously drives the rubber pad 203 and the air insulation layer 20 4. When the aluminum box reflective layer 205 and the high temperature resistant glass wool 206 are in contact with the first curved plate 201, the limiting block 211 is pushed backward to release the handle 210, and the handle 210 drives the sliding block 209a, and the spring 209c rebounds, so that the sliding block 209a drives the connecting block 209d, and the connecting block 209d drives the pin 209e to be inserted into the slot 209f on the fixed block 208, thereby completing the installation of the first curved plate 201, the second curved plate 202, the rubber pad 203, the air insulation layer 204, the aluminum box reflective layer 205 and the high temperature resistant glass wool 206. The first magnet 214 and the second magnet 215 provided on the first curved plate 201 and the second curved plate 202 can make the first curved plate 201 and the second curved plate 202 more stably installed under the action of mutual attraction between the first magnet 214 and the second magnet 215.
