The two clamping plates 102 at the same end are movably connected to the outer walls of both sides of one end of the pipe body 3 respectively. The pipe body 3 can be clamped and fixed by the two clamping plates 102 at both ends, so that the fixing mechanism 1 can stably clamp and fix the pipe body 3.

[0034] In order to facilitate the installation and fixing of ventilation ducts, Figure 2-3 and Figure 5 As shown, the mounting mechanism 2 includes two mounting plates 201 and an adjusting knob 203.

The adjusting knob 203 is rotatably mounted on the top inner wall in the middle position of the fixed plate 101. A rotating plate 204 is fixedly sleeved on the bottom outer side of the adjusting knob 203. Pulling plates 205 are provided between the top ends of the rotating plate 204 and the middle position of the tops of the two mounting plates 201. The rotation of the adjusting knob 203 causes the rotating plate 204 to rotate. Through the traction of the traction plate 205, the distance between the two mounting plates 201 can be adjusted, so that the ventilation duct can be conveniently adapted to the installation work of installation parts of different sizes.

[0035] In order to make the clamping plate 102 able to stably clamp the pipe body 3, as shown in FIG. Figure 2 and Figure 4 As shown, the fixing mechanism 1 includes a connecting bolt 103, two of which are provided. The connecting bolt 103 is threadedly inserted between the top inner walls of the two clamping plates 102 at the same end. The connecting bolt 103 can connect the tops of the two clamping plates 102 at the same end, so that the clamping plates 102 can stably clamp and fix the pipe body 3.

[0036] In order to keep the mounting plate 201 stable during the movement, Figure 2 and Figure 4-5 As shown, the fixing mechanism 1 includes a movable groove 104, and four movable grooves 104 are provided. The four movable grooves 104 are respectively opened on the inner walls on both sides of the bottom ends of the fixing plate 101, and sliders 206 are fixedly installed on both ends of the top of the two mounting plates 201. The outer walls of the two sliders 206 on the same side are movably connected to the inner walls of the adjacent movable grooves 104. The movable grooves 104 can limit the movement of the sliders 206, so that the mounting plate 201 remains stable during the movement.

Figure 2-3 and Figure 5As shown, the two ends of the top of the rotating plate 204 are rotatably connected to the two traction plates 205 respectively, and the inner walls of the two traction plates 205 on one side away from the rotating plate 204 are rotatably connected to the tops of the two mounting plates 201 respectively. The rotation of the rotating plate 204 can drive the two mounting plates 201 to move relative to or away from each other through the traction action of the two traction plates 205, and the positions of the two mounting plates 201 can be adjusted, so that the device can be conveniently installed and fixed through the mounting plates 201.

[0038] In order to ensure that the fixing mechanism 1 can stably install and fix the mounting mechanism 2 and the pipeline body 3, as shown in FIG. Figure 2 and 4 As shown, the top cross-section of the fixing plate 101 is set as an H-shaped structure, the inner diameter of the clamping plate 102 is the same as the outer diameter of the pipe body 3, and the H-shaped fixing plate 101 can conveniently install and fix the installation mechanism 2, and at the same time, the four clamping plates 102 can stably clamp the pipe body 3.

The two pipe bodies 3 can be conveniently spliced ​​through the connection between the external thread and the adjacent internal thread.

[0040] The specific implementation method is as follows: when installing the heating and ventilation duct, the rotating plate 204 is rotated by rotating the adjusting knob 203, and then the two mounting plates 201 can be driven to move relative to or away from each other under the traction of the two traction plates 205, so that the two mounting plates 201 can be conveniently adjusted according to the position of the installation part, and then the mounting plate 201 can be connected to the installation part by using the fixing bolts to penetrate the mounting holes 202, so that the fixing mechanism 1 and the mounting mechanism 2 can be conveniently installed and fixed, and then multiple pipe bodies 3 are spliced ​​so that the external threads are connected to the adjacent internal threads, and then the pipe body 3 is placed on the top of the fixing plate 101, and then through The two clamping plates 102 at both ends are rotated from an inclined state to a vertical state, so that the two clamping plates 102 at both ends can clamp and fix the outer walls of the pipe body 3 at both ends, and then the tops of the two clamping plates 102 at the same end can be connected and fixed by connecting bolts 103, so that the pipe body 3 can be kept stable inside the fixing mechanism 1, so that the heating and ventilation duct can be kept stable during installation and use, thereby making the installation and disassembly of the ventilation duct more convenient, and improving the installation efficiency of the ventilation duct. This embodiment specifically solves the problem in the prior art that the device cannot be conveniently adjusted according to the size of the installation site, making the installation and disassembly of the ventilation duct inconvenient.
