AI Technical Summary
The existing double-sleeve sealing joints lack reinforcement devices during use, which may cause the steel pipe to fall off from the joint due to vibration or external factors during the connection, affecting the pipeline sealing.
A double-sleeve sealing joint is designed, and a reinforced structure includes a rotating sleeve, a thread groove, a thread sleeve, an inner groove, a support plate, a spring and a clamp column. Through the cooperation of these components, the reinforcement connection between the steel pipe and the butt nut is achieved.
Through the reinforcement structure, the steel pipes are effectively prevented from falling off during the connection process, ensuring the stability of the pipe seal, and preventing the butt nuts from loosening through the anti-fall structure, improving the reliability of the overall connection.

At this time, the steel pipe is inserted into the rotating sleeve, and then the top plate is pressed at the same time. At this time, the two sets of springs are compressed to drive the two clamping columns to be inserted into the grooves formed in the steel pipe. Then, the threaded sleeve is rotated to move horizontally on the outer surface of the threaded groove. When it is moved to the two top plates, the two clamping columns can be fixed, thereby achieving the purpose of reinforcing the connection between the butt nut and the steel pipe;
[0014] 2. This double ferrule sealing joint has an anti-falling structure. After the two butt nuts are butted together, the two ends of the fastening belt are placed on the top of the two butt nuts respectively, and then the two fixing pins are aligned with the slots and screwed in to fix the fastening belt. After fixing, the fastening belt is pulled up from the middle to divide it into two sections, and the cable tie is passed through the two positioning holes at the bottom and tightened and fixed from the side, thereby preventing the two butt nuts from loosening and falling off.
