Description

Technical Field

[0001] The utility model relates to the technical field of heating pipeline construction, in particular to a pipe head connecting device for heating pipeline construction. Background Art

[0002] Heating pipes refer to pipes used for heating purposes, and heating pipes refer to pipes that supply hot water or steam for heating. They are usually used in buildings such as residential areas, commercial areas, and office areas. When hot water or steam flows through the heating pipes, it can transfer heat to the air, raising the indoor temperature. Heating pipes can also be zoned according to the different needs of the building, so as to achieve temperature regulation in different areas. Heating pipes are divided into two types: floor heating and hot air heating.

[0003] However, when connecting the pipe heads of the existing heating pipes, it is not convenient to fine-tune the connecting device according to the height of the heating pipe after the connecting device is fixed, which leads to limitations in connecting the pipes. In view of the above problems, the inventors propose a pipe head connecting device for heating pipe construction to solve the above problems. Utility Model Content

The second rotating ring is rotated to cause the second bidirectional screw to drive the two clamping half rings to move toward each other until they fit together and slide on the outer surface of the sliding rod. In cooperation with the sealing plate, the two heating pipe heads can be connected and sealed. Then the pull rod is loosened to reset the spring and allow the groove in the positioning piece to clamp the toothed ring to each other, so that the second bidirectional screw can rotate on its own to prevent the two clamping half rings from separating and causing leakage of the heating pipe head.

[0007] Preferably, a clamping half-ring is provided in the installation frame for movement toward each other, a sealing plate is fixed in the clamping half-ring, a second bidirectional screw is rotatably provided in the installation frame, a second rotating ring is fixed on the top of the second bidirectional screw, the clamping half-ring is threadedly sleeved on the outer surface of the second bidirectional screw, a sliding rod is fixed in the installation frame, and the clamping half-ring is slidably provided on the outer surface of the sliding rod.
