[0031] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0032] A heating, ventilation and insulation device, such as Figures 1-8As shown, the system includes a main body 1 and a main body 2. Both main bodies 1 and 2 have an insulation layer 8 fixedly installed inside. A sealing gasket 9 is fixedly connected to one end of main body 1 near main body 2. A connecting mechanism is provided between the exterior of main bodies 1 and 2. Both main bodies 1 and 2 have an installation mechanism on their exteriors. The connecting mechanism includes an annular connecting plate 10, an annular fixing plate 4, and an annular limiting plate 5. The annular connecting plate 10 is fixedly connected to the outer wall of main body 1. The annular fixing plate 4 and the annular limiting plate 5 are both fixedly connected to the outer wall of main body 2. An annular movable plate 3 is movably installed on the exterior of the annular connecting plate 10.

[0033] Among them, the sealing gasket 9 can fill the gap between the main body 1 and the main body 2, making the connection between the two tighter and avoiding gaps.

[0034] The outer wall of the annular connecting plate 10 has an annular groove 12. Several T-shaped sliders 11 are inserted inside the annular groove 12, and one end of each T-shaped slider 11 is fixedly connected to the annular movable plate 3. An insert ring 35 is fixedly connected to the outer wall of the annular movable plate 3. Several movable grooves 17 are opened on the outer wall of the insert ring 35. A locking block 18 is inserted inside each movable groove 17. Several spring pieces 20 are installed between the bottom end of the locking block 18 and the inner wall of the movable groove 17. A movable ring 16 is movably installed on the side of the annular fixed plate 4 near the annular limiting plate 5.

[0035] Several sliding rods 15 are inserted into the outer wall of the movable ring 16, and one end of each sliding rod 15 is fixedly connected to the annular fixing plate 4. A spring is sleeved on the outside of the sliding rod 15 and located between the movable ring 16 and the annular fixing plate 4. A fixing rod 19 is fixedly connected to the outer wall of the movable ring 16. A fixing hole is opened on the outer wall of the locking block 18, and the fixing hole fits with the fixing rod 19. Several slots 13 and grooves 14 are opened on the outer wall of the annular limiting plate 5, and the slots 13 and grooves 14 fit with the locking block 18. Under the action of the elastic force of the spring piece 20, it can be inserted into the slot 13 to fix the position of the insertion ring 35 in the annular limiting plate 5, thus completing the initial fixation with the main body 1 and the main body 2.

[0036] In use, the main body 1 and the main body 2 are respectively fitted onto the outside of two HVAC pipes to insulate them. The main body 1 and the main body 2 are made of polyurethane foam, which is corrosion-resistant and wear-resistant. The insulation layer 8 inside the main body 1 and the main body 2 is made of rubber, which has excellent insulation performance, effectively insulating the HVAC pipes. When it is necessary to connect the main body 1 and the main body 2 to insulate the two connected HVAC pipes, the insert ring 35 installed on the outer wall of the annular movable plate 3 can be inserted into the annular limiting plate 5, causing each locking block 18 to engage with each groove 14. Then, by rotating the annular movable plate 3 outside the annular connecting plate 10 with the T-shaped slider 11 and the annular groove 12, the insert ring 35 rotates, and each locking block 18 rotates accordingly. The inclined surface of the locking block 18 moves along the inner wall of the groove 14. As the spring 20 gradually contracts into the movable groove 17, it is compressed. With the rotation of the insert ring 35, the locking block 18 enters the annular limiting plate 5 until it rotates to a position close to the slot 13. Under the action of the elastic force of the spring 20, the locking block 18 can be locked into the slot 13, fixing the position of the insert ring 35 in the annular limiting plate 5, completing the initial fixation with the main body 1 and the main body 2. At this time, with the cooperation of the elastic force of the spring, the moving ring 16 moves closer to the annular limiting plate 5 along the slide rod 15, allowing the fixing rod 19 to be inserted into the fixing hole, fixing the position of the locking block 18, thereby further improving the stability of the connection, so that the main body 1 and the main body 2 can be easily connected together without the aid of external tools, effectively improving the work efficiency of heat preservation for multiple connected HVAC pipes.

[0037] like Figure 6-Figure 8 As shown, the installation mechanism includes a collar 6 and two annular fixing plates 7. Both annular fixing plates 7 are fixed to the outer wall of the main body 2. The collar 6 is sleeved on the outside of the main body 2 and located between the two annular fixing plates 7. The outer wall of the annular fixing plates 7 has several insertion holes 1 and the outer wall of the collar 6 has several insertion holes 2. A fixing nail 21 is inserted into one of the insertion holes 1, and one end of the fixing nail 21 fits into the insertion hole 2. By passing the fixing nail 21 through the corresponding insertion hole 1 and inserting it into the corresponding insertion hole 2, the position of the collar 6 can be fixed.

[0038] A U-shaped block 36 is fixedly connected to the outer wall of the collar 6. A telescopic plate 25 is movably connected inside the U-shaped block 36. A connecting plate 22 is sleeved on one end of the telescopic plate 25. A connecting shaft 28 is inserted into the outer wall of the connecting plate 22 near one end. A telescopic plate 24 is fixedly connected to one end of the connecting shaft 28. A circular plate 27 is fixedly connected to the other end of the connecting shaft 28. A fixing ring 37 is fixedly connected to the outer wall of the connecting plate 22 and located outside the circular plate 27.

[0039] A connecting plate 23 is fitted onto one end of a telescopic plate 24. A mounting plate 26 is movably installed on the end of the connecting plate 23 away from the telescopic plate 24. Screws 34 are inserted into the outer walls of both the mounting plate 26 and the U-shaped block 36. Nuts are fitted onto the outer ends of the screws 34. Fixing bolts are inserted into the outer walls of both the connecting plate 23 and the connecting plate 22. Several screw holes are formed on the outer walls of both the telescopic plate 24 and the telescopic plate 25, and these holes cooperate with the fixing bolts. By rotating the fixing bolts through the connecting plate 22 into the corresponding screw holes, the position between the connecting plate 22 and the telescopic plate 25 can be fixed, thereby adjusting the extension length of the telescopic plate 25. Similarly, the extension length of the telescopic plate 24 can be adjusted. By rotating the two nuts along the screws 34, the position between the telescopic plate 25 and the U-shaped block 36 is compressed, thus fixing the position between them. Similarly, the position between the mounting plate 26 and the connecting plate 23 can be fixed.

[0040] A rotating block 31 is rotatably connected to the outer wall of the circular plate 27 via a shaft. Two telescopic connecting rods 32 are fixedly connected to one end of the rotating block 31. A movable block 30 is fixedly connected to one end of each of the two telescopic connecting rods 32. A spring is sleeved on the outside of each of the two telescopic connecting rods 32. An insert plate 33 is fixedly connected to the bottom surface of the rotating block 31. Several fixing slots are opened through the outer wall of the circular plate 27, and the fixing slots fit into the insert plate 33.

[0041] Specifically, when connecting the main body 1 and the main body 2 to a wall or other installation location, the mounting plate 26 can be rotated by rotating the collar 6 between the two annular fixing plates 2 7, bringing the mounting plate 26 closer to the location to be fixed. After adjustment, the fixing nail 21 can be inserted through the corresponding insertion hole 1 into the corresponding insertion hole 2 to fix the position of the collar 6. The distance between the mounting plate 26 and the installation location can be adjusted by moving the connecting plate 22 along the outside of the telescopic plate 2 25 and the connecting plate 23 along the outside of the telescopic plate 2 24. The placement angle of the mounting plate 26 can be adjusted by rotating one end of the telescopic plate 2 25 with the screw 34 installed on the U-shaped block 36 as the central axis and by rotating the mounting plate 26 with the screw 34 installed on the mounting plate 26 as the central axis. The position of the mounting plate 26 can be adjusted by rotating the movable block 30 away from the center. Moving block 31 causes insert plate 33 to move out of the fixed slot. Telescopic connecting rod 32 and spring 2 are stretched, which releases the fixation between circular plate 27 and fixed ring 37, thereby releasing the fixation between connecting shaft 28 and connecting plate 22. At this time, telescopic plate 24 can be rotated by connecting shaft 28, which drives mounting plate 26 to rotate, further adjusting the angle of mounting plate 26. After adjustment, release moving block 30. Under the action of spring 2, moving block 30 can be moved to the initial position, driving insert plate 33 to be inserted into the corresponding fixed slot, fixing the position between connecting shaft 28 and connecting plate 22. Through the above operation, the angle and position of mounting plate 26 can be flexibly adjusted to adapt to different installation positions, and the main body 1 and main body 2 can be conveniently installed and fixed in the designated position.

[0042] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
