[0002] When installing air conditioners in the existing market, in order to connect the connecting pipes of the air conditioner to the outside world, the connecting pipes of the air conditioner are generally connected to the installation pipes of the outside world to achieve the effect of normal ventilation. Therefore, when connecting the pipes, the pipe connecting device is used. When connecting the pipes in the existing market, the connecting pipe at the top of the flange is generally connected to the pipe on one side, and the other pipe is connected to the connecting pipe at the top of the other flange. After that, a flange gasket is installed between the two flanges. Finally, the connection of the two flanges is completed by tightening the bolts and nuts, thereby completing the connection of the pipes. When the above-mentioned pipe connection is connected, in order to ensure the indoor space layout and beauty, the pipe is generally installed at the top corner of the room. When the pipe is installed at the top corner, it will appear that when the flange connection is performed, the perforation on one side of the outside of the flange is close to the wall. When the screw and the nut are fixed, the nut is generally controlled to rotate by a wrench to complete the tightening. However, since the size of the wrench is generally fixed, when the space environment is relatively limited, it will make it very inconvenient to control the wrench to rotate the nut.

[0028] The inner fastening mechanism includes a gear nut 6 and a screw rod 4 , and the outer fastening mechanism includes a screw rod 4 and a square nut 5 . The inner fastening mechanism is controlled by the rotating mechanism 3 to perform a rotational fastening operation.

[0029] The flange mechanism 1 comprises a flange plate 11 and a connecting pipe 12, and the two are installed as one body, and the outer side of the flange plate 11 is provided with 7 holes distributed at equal angles;

[0030] An annular sliding groove 8 is also embedded on the outer side of the flange 11 . The sliding groove 8 is provided to facilitate the subsequent rotating mechanism 3 to slide stably on the outer side of the flange 11 .

[0031] The outside of the flange gasket 2 is also provided with 7 through holes distributed at equal angles, and the sizes of the through holes are the same as those of the outside of the flange plate 11 .

[0032] The rotating mechanism 3 comprises:

[0033] The connecting cover 31 is annular in structure, a slip ring 32 is integrally mounted on one side of the bottom, and gear blocks 33 are distributed at equal angles on the inner side of the top of the connecting cover 31;

[0034] The outer side of the connection cover 31 is provided with four reserved holes 9 distributed at equal angles, and the inside of the reserved holes 9 is provided with fastening bolts 7 for connection with the flange 11;

[0035] The square nut 5 is arranged in a polygonal structure, and its size is smaller than the circular size of the outer side of the gear nut 6, and the meshing teeth on the outer side of the gear nut 6 mesh with the tooth block 33;

[0036] When the connecting cover 31 rotates, it can mesh with the meshing teeth outside the gear nut 6 to achieve the effect of driving the gear nut 6 to rotate.

[0037] Working principle: When using the HVAC pipe connection device, when connecting pipes, first control the connecting pipe 12 on a flange mechanism 1 to engage with the inside of one pipe, and the connecting pipe 12 outside the other flange mechanism 1 to engage with the inside of another pipe. Then, place the flange gasket 2 in the middle of the two flanges 11, control the perforations on the flange gasket 2 to correspond to the positions of the perforations on the two flanges 11, and then insert the screw 4 into each perforation. Then, the two sides of the screw 4 at the outer position are respectively threadedly connected to the square nuts 5, and then the gear nut 6 is threadedly connected to the screw 4 at the inner position. Then, first, the square nut 5 can be rotated by a wrench to complete the rotation and tightening work;

[0038] Then the staff only needs to control the connection cover 31 to rotate from the outside, so that the slip ring 32 on the inside of the connection cover 31 rotates in the slide groove 8. When the connection cover 31 rotates, the tooth block 33 on the inside thereof rotates. When the tooth block 33 rotates, it meshes with the external meshing teeth on the gear nut 6, so that the gear nut 6 rotates. At this time, by controlling the position of the screw rod 4, the tightening work on the inside can be completed. After rotating to the appropriate position, the tightening bolt 7 is controlled to pass through the reserved hole 9 on the outside of the connection cover 31 and the inner wall of the slide groove 8 for tightening, thereby achieving the connection work of the two pipes.
