The utility model is further illustrated by the following examples in conjunction with the accompanying drawings:
example 1: a building heating and ventilation pipeline connecting device, see fig. 1-4, comprises a connecting pipe 1 and a positioning structure 2;
the two positioning structures 2 are respectively arranged at the two ends of the connecting pipe 1;
The positioning structure 2 comprises a half clamping ring A201, a connecting block A203, a half clamping ring B202, a connecting block B204 and a guide rod 205;
The half clamping ring A201 is fixedly arranged at the bottom side of the end part of the connecting pipe 1; the two connecting blocks A203 are respectively fixedly arranged on the outer walls of the two ends of the half clamping ring A201; the half clamping ring B202 is movably arranged at the top side of the end part of the connecting pipe 1; the two connecting blocks B204 are respectively fixedly arranged on the outer walls of the two ends of the half clamping ring B202; the two guide rods 205 are respectively penetrated through the two connecting blocks A203; one end of the guide rod 205 is fixedly connected with the connecting block B204.
According to the utility model, the half clamping ring A201, the connecting block A203, the half clamping ring B202, the connecting block B204 and the guide rod 205 are arranged, so that the space between the half clamping ring B202 and the half clamping ring A201 is increased, the warm-through pipeline port is conveniently inserted into and is in butt joint with the end opening of the connecting pipe 1, and the problem that more efforts are spent on staff due to the fact that the warm-through pipeline port and the connecting piece port need to be completely aligned when being inserted is solved.
Specifically, half of the inner ring side of the half clamping ring A201 and half clamping ring B202 are connected with the end part of the connecting pipe 1. The connection part of the end opening of the heating and ventilation pipeline port connecting pipe 1 is covered by a half clamping ring A201 and a half clamping ring B202.
Further, a limiting block 206 is fixed at the other end of the guide rod 205; the diameter of the limiting block 206 is larger than the diameter of the opening of the connecting block A203.
The utility model has the advantages of limiting the moving guide rod 205 and avoiding the guide rod 205 from being separated by arranging the limiting block 206.
Still further, a sealing strip 2021 is fixedly arranged on the inner ring of the half clamping ring B202; wherein, the sealing strip 2021 is arranged along the inner ring and two ends of the half snap ring B202; clamping grooves B2011 are respectively formed in two ends of the half clamping ring A201, each clamping groove B2011 is L-shaped, a clamping groove A101 is formed in the top side of the outer wall of the end part of the connecting pipe 1, and the clamping grooves A101 are communicated with the two clamping grooves B2011; wherein, sealing strip 2021 is inserted and matched with clamping groove A101 and two clamping grooves B2011.
