Detailed Description

Example one

As shown in fig. 1-8, the present invention provides a self-fastening type bellows joint structure, which includes a tubular joint, a sealing ring 2 and a threaded sleeve 3, wherein the tubular joint is a straight pipe joint 100, an elbow joint 200, a tee pipe joint 300 or a four-way pipe joint 400.

As shown in fig. 9, fig. 9 shows only a specific structure of a four-way pipe joint 400, the specific structure of the other shape joint is the same as that of the four-way pipe joint, the pipe joint end is a connecting pipe portion, the connecting pipe portion is an annular pipe, external threads 102 are arranged on the outer periphery of the connecting pipe portion, a plurality of deformation grooves 101 are arranged at the outer end of the connecting pipe portion and divide the external threads 102 into a plurality of sections, a seal ring 2 is arranged on the inner peripheral surface of the connecting pipe portion, a screw sleeve 3 is provided with internal threads matched with the external threads 102, and the screw sleeve 3 is in threaded connection with the connecting pipe portion.

This embodiment can carry out firm sealing connection to the bellows. When in use, the corrugated pipe passes through the thread insert 3 and is inserted into the connecting pipe part, so that the wave trough of the corrugated pipe can be clamped at the sealing ring 2. At this moment, the screw sleeve 3 is in an active state, then the screw sleeve 3 is screwed to the external thread 102 on the connecting pipe portion, along with the screwing of the screw sleeve 3, the structure of the external thread 102 on the connecting pipe portion can be inwards compressed on the corrugated pipe, the deformation groove 101 enables the smooth deformation of the structure above, the corrugated pipe is finally compressed along the circumferential direction through the connecting pipe portion, the firmness of corrugated pipe connection is improved, the sealing ring 2 is not prone to deviation and dislocation, leakage is avoided, and the sealing effect can be effectively guaranteed.
