[0027] 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.

[0028] like Figures 1 to 7 As shown, a building HVAC pipe connection joint includes an HVAC pipe body 1, a connecting pipe 2 fixedly installed on one side of the HVAC pipe body 1, a pipe joint 3 snapped onto the outer surface of the connecting pipe 2, fixing blocks 4 fixedly installed at both ends of the HVAC pipe body 1, movable rotating plates 5 rotatably installed on one side of each of the two fixing blocks 4, and mounting blocks 6 fixedly connected to both ends of the pipe joint 3.

[0029] One side of each of the two movable rotating plates 5 is slidably connected with a positioning rod 7 for fixing the movable rotating plate 5. A connecting spring 8 is fixedly connected between each of the two positioning rods 7 and the fixing block 4. One end of each of the two mounting blocks 6 is provided with an embedding groove 10. The other side of the positioning rod 7 is engaged and placed inside the embedding groove 10. One side of each of the two movable rotating plates 5 is threadedly connected with a fastening bolt 11 for fixing the movable rotating plate 5. The other end of each of the two mounting blocks 6 is provided with a threaded groove 12. The interior of each of the two mounting blocks 6 is slidably engaged with two L-shaped locking blocks 13 for fixing the movable rotating plate 5.

[0030] A mounting plate 26 is fixedly installed above the main body 1 of the HVAC pipe and the pipe joint 3. Four brackets 27 are fixedly connected to the lower side of the mounting plate 26. Support recesses 28 for supporting the connection joint of the building HVAC pipe are fixedly installed on the lower side of two brackets 27.

[0031] A rubber sealing sleeve 19 is fixedly connected to the outer surface of the connecting pipe 2, and a rubber sealing sleeve 20 is fixedly connected to the inside of the connecting pipe 2. The rubber sealing sleeve 19 and the rubber sealing sleeve 20 are used to seal the connection joint of the building heating and ventilation pipes. Through the installation and use of the rubber sealing sleeve 19 and the rubber sealing sleeve 20, the two can fit tightly together, so the two rubber sealing sleeves can play a sealing role, which can improve the sealing performance of the heating and ventilation pipe connection joint and prevent the leakage of air, water or other media. Fixing plates 21 are fixedly installed at both ends of the pipe joint 3.

[0032] Both sides of the HVAC duct body 1 are fixedly installed with fixing plates 22. The inside of the two fixing plates 21 and the fixing plates 22 are snapped with first U-shaped plates 23. The side of each of the two first U-shaped plates 23 is snapped with a second U-shaped plate 24 for fixing the first U-shaped plate 23. One end of each of the two first U-shaped plates 23 is threaded with a fastening bolt 25 for fixing the second U-shaped plate 24. The fastening bolt 25 can be used to fix the second U-shaped plate 24, so that the two first U-shaped plates 23 can more stably position the HVAC duct body 1 and the duct joint 3.

[0033] One side of the positioning rod 7 passes through the movable rotating plate 5 and extends into the interior of the movable rotating plate 5. A connecting plate 9 is fixedly provided on one side of each of the two positioning rods 7. Moving the connecting plate 9 can cause the elastic positioning rod 7 to compress, so as to release the fixation on the movable rotating plate 5. This is used for disassembling the HVAC pipe body 1 and the pipe joint 3. One side of the mounting block 6 is snapped into the interior of the movable rotating plate 5. The outer surface thread of the fastening bolt 11 is placed inside the thread groove 12. One side of the L-shaped locking block 13 is snapped into the interior of the fixing block 4. Two L-shaped elastic blocks 14 are fixedly provided on one side inside the HVAC pipe body 1.

[0034] Each of the two L-shaped elastic blocks 14 has a groove 16 on one side. The pipe joint 3 has two L-shaped grooves 15 on one side. One end of the L-shaped elastic block 14 is engaged inside the L-shaped groove 15. The bottom of the pipe joint 3 is fixedly connected to two inclined plates 17. Both ends of the two inclined plates 17 are fixedly connected to rubber convex pads 18. One side of the inclined plate 17 is engaged with the inside of the groove 16. By setting the L-shaped elastic block 14, pressing the L-shaped elastic block 14 allows the two rubber convex pads 18 at the inclined plate 17 to engage with the groove 16 at the L-shaped elastic block 14. This is used to limit the L-shaped elastic block 14 and release the fixation of the HVAC pipe body 1 and the pipe joint 3, and to disassemble the HVAC pipe connection joint.

[0035] The working principle of the building HVAC pipe connection joint provided by this utility model is as follows:

[0036] By snapping the pipe joint 3 onto the connecting pipe 2 of the HVAC pipe body 1, the HVAC pipe body 1 and the pipe joint 3 are initially positioned. Then, the connecting plate 9 is pulled, which compresses the connecting plate 9 and retracts the positioning clamp 7 equipped with the connecting spring 8. Then, the two movable rotating plates 5 are rotated, so that the two movable rotating plates 5 are snapped onto the two mounting blocks 6. Next, the elastic positioning clamp 7 is released, so that the positioning clamp 7 is snapped into the embedded groove 10 of the mounting block 6. Then, the two fastening bolts 11 are tightened, so that the fastening bolts 11 are fixed into the threaded groove 12 of the mounting block 6, so as to fix the HVAC pipe body 1 and the pipe joint 3. Then, the four L-shaped clamps 13 are pushed, so that the L-shaped clamps 13 are fixed into the movable rotating plate 5 and the mounting block 6. In this snap-fit ​​assembly method, the HVAC pipe body 1 and the pipe joint 3 can be conveniently assembled to form a building HVAC pipe connection joint without the need for flanges and bolts, saving time and effort and improving the loading and unloading efficiency of the building HVAC pipe connection joint.

[0037] By utilizing the mounting plate 26, bracket 27, and support recess 28, the building HVAC pipe connection joint can be supported and reinforced, making the building HVAC pipe connection joint safer and more stable to use. With the installation of the pipe joint 3, the two L-shaped elastic blocks 14 at the main body 1 of the HVAC pipe can be snapped into the L-shaped groove 15 of the pipe joint 3 to further fix the main body 1 of the HVAC pipe and the pipe joint 3. Then, the first U-shaped plate 23 is snapped into the fixing plate 1 21 and the fixing plate 22, and then the second U-shaped plate 24 is inserted into the inside of the first U-shaped plate 23. Then, the two fastening bolts 25 are tightened to fix the second U-shaped plate 24, so as to reinforce the connection of the main body 1 of the HVAC pipe and the pipe joint 3 around the perimeter, thereby improving the stability of the building HVAC pipe connection joint.
