Detailed Description

In the following description, numerous implementation details are set forth in order to provide a more thorough understanding of the present invention. It should be understood, however, that these implementation details should not be used to limit the invention. That is, in some embodiments of the invention, details of these implementations are not necessary. In addition, some conventional structures and components are shown in simplified schematic form in the drawings.

In addition, the descriptions related to "first", "second", etc. in the present invention are only for description purposes, not specifically referring to the order or sequence, and are not intended to limit the present invention, but only to distinguish the components or operations described in the same technical terms, and are not to be construed as indicating or implying any relative importance or implicit indication of the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one such feature. In addition, the technical solutions in the embodiments may be combined with each other, but it must be based on the realization of those skilled in the art, and when the technical solutions are contradictory or cannot be realized, the combination of the technical solutions should not be considered to exist, and is not within the protection scope of the present invention.

The utility model discloses a telescopic connection joint, including inner tube body 1 and outer tube body 2, outer tube body 2 suit is in the outside of inner tube body 1, is provided with seal structure between outer tube body 2 and the inner tube body 1, is provided with anti-disengaging structure between inner tube body 1 and outer tube body 2, wherein one end integrated into one piece of inner tube body 1 has joint portion 11, and the one end of outer tube body 2 that is kept away from joint portion 11 is provided with connecting portion 21; the joint part can adopt a thread type joint part, a plug-in type joint part and the like; the utility model discloses a setting of interior body and outer body, interior body can stretch out and draw back for outer body, so, can adjust attach fitting's length to can improve attach fitting's application scope.

The sealing structure comprises a first sealing ring 3 embedded between the outer pipe body 2 and the inner pipe body 1, an annular embedding groove 22 for embedding the first sealing ring 3 is formed in the inner peripheral wall of one end, facing the connecting part 21, of the outer pipe body 2, and the first sealing ring 3 is tightly attached to the inner peripheral wall of the annular embedding groove 22 and the outer peripheral wall of the inner pipe body 1; by adopting such a sealing structure, after the first seal ring is in close contact with the inner peripheral wall of the annular caulking groove and the outer peripheral wall of the inner pipe body, the outer pipe body and the inner pipe body can be reliably sealed.

The anti-falling structure comprises a clamp spring 4, an annular clamping groove 12 is formed in the outer peripheral wall of one end, far away from the joint part 11, of the inner pipe body 1, the clamp spring 4 is clamped with the annular clamping groove 12 in a matched mode, and an annular groove 23 which is open at one end and used for the clamp spring 4 to enter and exit is formed in the inner peripheral wall of the outer pipe body 2; after adopting this kind of anti-disengaging structure, when the relative outer body of body removed including, for example when interior body removed the leftmost end, the joint portion can offset with outer body, for example again, when interior body removed the rightmost end, the jump ring can offset with the interior bottom of annular groove, so, can play the effect of anticreep.
