Embodiment 1
[0033] Such as Figure 1 to Figure 5 As shown, a brand-new threaded metal bellows joint includes a connecting pipe body 1 that is threadedly matched with the bellows, and a fixed ring 2 is fixed inside the connecting pipe body 1, and two Both sides are provided with seals 3 . The positioning ring 2 is used to control the connection length and the sealing member 3 realizes a reliable and effective sealing connection effect for the corrugated pipe to be connected, and realizes the effect that the connecting pipe body 1 and the corrugated pipe are not easy to fall off after being connected.
[0034] In a further preferred solution of this embodiment, both ends of the connecting pipe body 1 are provided with an anti-disengagement assembly, and the anti-disengagement assembly includes a fixing piece 6 fixedly installed at the end of the connecting pipe body 1 and a rotatably connected fixing piece 6 The inner anti-off piece 4 is provided with a torsion spring at the rotational con...
Embodiment 2
[0042] A construction method for a brand-new threaded metal bellows joint, comprising the following steps:
[0043] A. First, adjust the adjusting member 12 to push the fixed frame 13 to move along the guide channel 11 to the side close to the central axis of the connecting pipe body 1. During the process, the clamping part 152 of the clamp claw 15 will be affected by the guide channel 11 along the length direction of the guide rail 16. Moving inwardly, the guide portion 151 also moves inwardly along the length direction of the guide rail 16 and compresses the return spring 17;
[0044] B. Secondly, adjust the position of the positioning pin 10 so that it is separated from a set of positioning holes 8 on the side close to the central axis of the bellows, and move to a set of positioning holes 8 on the side away from the central axis of the bellows and align with the positioning holes there. 8, and then the bellows to be connected and the connecting pipe body 1 are threaded unt...
