[0002] As an indispensable part of modern buildings, the efficiency, safety and reliability of the design and installation of air-conditioning systems are directly related to the comfort of the indoor environment and the efficient use of energy. In air-conditioning systems, pipe connection devices play a vital role. They are not only responsible for transporting hot and cold air to every room, but also affect the sealing of the entire system, the cooling / heating efficiency and the convenience of maintenance.

[0003] The history of air conditioning pipe connection devices can be traced back to the beginning of the birth of air conditioning systems. Early air conditioning systems mostly used simple straight pipe connections and were fixed by threads or flanges.

[0009] Optionally, the unlocking mechanism further includes a connecting ring and a torsion spring, the connecting ring is connected to the fixed ring, and two ends of the torsion spring are respectively connected to the connecting ring and the rotating ring.

[0010] Optionally, a shielding mechanism is also included, which includes a spring II and a plate, one end of the spring II is connected to the slot of the pipe II, and the other end of the spring II is connected to the plate, which is used to shield the slot of the pipe II.

[0011] The beneficial effects of the utility model are as follows: 1. The utility model can insert the card block into the card slot through the cooperation of the fixing ring, the card block and the spring I, so that the card block limits the pipe II, thereby quickly splicing the pipe II with the pipe I, and then using the unlocking mechanism to quickly disconnect the pipe II from the pipe I. Not only is the structure simple, the operation is convenient, and time and labor are saved, but also by setting a sealing ring, the sealing between the pipe I and the pipe II can be improved, thereby preventing air leakage.

[0023] See also Figure 2 As shown, it also includes a limiting ring 7; the limiting ring 7 is installed inside the pipeline Ⅰ1. After the pipeline Ⅱ2 extends into the pipeline Ⅰ1, the pipeline Ⅱ2 will contact the limiting ring 7, so that the limiting ring 7 limits the pipeline Ⅱ2 to prevent the pipeline Ⅱ2 from extending too far into the pipeline Ⅰ1.

[0024] See also Figure 2As shown, a sealing ring 8 is also included; the sealing ring 8 is installed in the pipeline Ⅰ1. After the pipeline Ⅱ2 extends into the pipeline Ⅰ1, the outer wall of the pipeline Ⅱ2 will contact the sealing ring 8, so that the sealing ring 8 is used to seal the pipeline Ⅰ1 and the pipeline Ⅱ2 after docking.

[0025] See also Figure 2 As shown, an unlocking mechanism is also included, which includes a lever 9, a rotating ring 10, a connecting ring 11 and a torsion spring 12; the lever 9 is connected to the side of the two clamping blocks 4 that are away from each other; the rotating ring 10 is rotatably connected to the outside of the fixed ring 3, and the rotating ring 10 will contact the lever 9 when rotating, so that the rotating ring 10 squeezes the lever 9 to move, so that the lever 9 drives the clamping block 4 to move, and then the clamping block 4 leaves the clamping slot 6; the connecting ring 11 is connected to the outside of the fixed ring 3; the two ends of the torsion spring 12 are respectively connected to the connecting ring 11 and the rotating ring 10, so that the rotating ring 10 can be reset by the torsion spring 12 after rotation.

[0026] See also Figure 1 and Figure 4 As shown, a shielding mechanism is also included, which includes a spring II 13 and a plate 14; one end of the spring II 13 is connected to the slot 6 of the pipe II 2; the other end of the spring II 13 is connected to the plate 14, and the plate 14 is used to shield the slot 6 of the pipe II 2 to prevent foreign matter from being stuck in the slot 6 of the pipe II 2 and causing subsequent impact on the insertion of the card block 4.

[0027] When in use, move pipe II 2 to the left close to pipe I 1, so that pipe II 2 enters pipe I 1 through fixing ring 3 until pipe II 2 contacts with limiting ring 7 in pipe I 1; after pipe II 2 enters fixing ring 3, pipe II 2 contacts with inclined surface 41 of card block 4, at this time, pipe II 2 uses inclined surface 41 to squeeze card block 4 to move away from each other, spring I 5 stretches, when card block 4 is aligned with card slot 6 on pipe II 2, spring I 5 returns to its original state, spring I 5 drives card block 4 to move to the side close to each other and reset, when card block 4 contacts with pasting plate 14, card block 4 squeezes pasting plate 14 to move to the side close to each other (the elastic force of spring I 5 is greater than the elastic force of spring II 13), spring II 13 is compressed, and pasting plate 14 is pressed to move to the side close to each other. The plate 14 no longer blocks the card slot 6, and the card block 4 is inserted into the card slot 6, so that the card block 4 limits the pipe II 2, so that the pipe II 2 and the pipe I 1 are quickly spliced, and after the pipe II 2 contacts the limiting ring 7 in the pipe I 1, the limiting ring 7 will block the pipe II 2 from continuing to move, so that the limiting ring 7 limits the pipe II 2 to prevent the pipe II 2 from continuing to move and causing the card block 4 to be separated from the card slot 6, and before the pipe II 2 contacts the limiting ring 7, the pipe II 2 will first contact the sealing ring 8, and the sealing ring 8 can be used to seal the pipe I 1 and the pipe II 2, thereby improving the sealing between the pipe I 1 and the pipe II 2, and after the pipe II 2 and the pipe I 1 are spliced, the pipe I 1 and the pipe II 2 can be loosened;

[0028] When it is necessary to disconnect the pipeline Ⅰ1 and the pipeline Ⅱ2 for maintenance, the rotating ring 10 is twisted to rotate, and the torsion spring 12 is deformed. When the rotating ring 10 contacts the lever 9, the rotating ring 10 squeezes the lever 9 to move away from each other, thereby driving the block 4 to move away from each other. The spring Ⅰ5 is stretched to make the block 4 leave the slot 6, so that the block 4 releases the limit on the pipeline Ⅱ2, and when the block 4 is separated from the plate 14, the spring Ⅱ13 returns to its original state, and the spring Ⅱ13 drives the plate 14 to move away from each other. Reset, so that the sticking plate 14 covers the card slot 6 again, thereby preventing foreign objects from getting stuck in the card slot 6, and then pull the pipe Ⅱ2 to the right to make the pipe Ⅱ2 leave the pipe Ⅰ1 and the fixed ring 3, and finally release the rotating ring 10, the torsion spring 12 returns to its original state, and the torsion spring 12 drives the rotating ring 10 to reverse and reset. When the rotating ring 10 is separated from the lever 9, the spring Ⅰ5 returns to its original state, and the spring Ⅰ5 drives the block 4 and the lever 9 to move to the side close to each other and reset. In this way, the pipe Ⅰ1 and the pipe Ⅱ2 can be quickly disconnected for subsequent maintenance.
