Embodiment

Below in conjunction with accompanying drawing specific embodiment of the utility model is illustrated:

As Fig. 2, shown in Figure 3, pipe joint structure of the present utility model, an end of its pipe joint 3 is established an opening 31, and the other end is an extending end 32, and extending end 32 is mainly a screwed pipe, so that group goes into to desire installed device or assembly; As shown in the figure, the inside of pipe joint 3 is formed with a tubular holding space 4, the lower end of tubular holding space 4 and extension part outlet 321 communicate, tubular holding space 4 is provided with two

necks

41,42 from lower to upper at least, first neck 41 is positioned at the below, and mainly in order to provide O shape ring leak-proof gasket 5 to place, second neck 42 is located at the higher position, mainly put in order to hold belled part 6, the inwall between second neck 42 and the opening also is provided with together circular groove 33 along the wall indent;

This belled part 6 is the endless tube shape of running through up and down, and its underpart is provided with fluting 61 at interval, is intermediate plate 62 between each fluting, and intermediate plate 62 has the elasticity that outwards struts, and intermediate plate 62 inner faces are provided with a metal double wedge 63, and this metal double wedge 63 has downward inclined-plane; In addition, the outer surface of this belled part 6 forms outside protrusion in the upper end that connects intermediate plate 62, and then there is an outward extending flange 64 on the top of this belled part 6, forms the bundle neck space 65 of an indent with this between intermediate plate 62 upper ends and flange 64;

One collar 7, have one can be from lower to upper passage 71 by intermediate plate 62, make it can wholely be inserted in the bundle neck space 65 of belled part 6, and because its upper-end inner diameter is little than the top flange 64 of belled part, and, its bottom diameter is also little than bump on the intermediate plate, make it organize the bundle neck space 65 of belled part after, in bundle neck space 65 be state is established in the work that moves up and down; And there is a lip ring 72 big than the tubular holding space internal diameter of pipe joint on the top of this collar 7, also there is a ring rib 73 its outside, after making the collar 7 and belled part 6 insert the tubular holding space 4 of pipe joint together, must utilize the indent circular groove 33 of the tubular holding space of ring rib 73 embeddings of the collar, make belled part 6 be incorporated into pipe joint apace, and can in the tubular holding space 4 of pipe joint, appropriateness move.

During enforcement, as shown in Figure 4, at first the collar 7 is inserted in from lower to upper the bundle neck space 65 of belled part 6, make the collar 7 must be in bundle neck space 65 appropriateness movable, again with the tubular holding space 4 of the belled part 6 ascending pipe joints 3 of the sheathed collar 7, after the collar 7 entered tubular holding space 4, it is fixing that its outside ring rib 73 embeds within the tubular holding space

hollow toroid groove

33,6 of belled parts because of the collar 7 build-ins in pipe joint 3, and can be in tubular holding space 4 can appropriateness movable.

Therefore, insert the internal diameter passage of belled parts 6 when outer tube 8 after, the constraint that belled part 6 is subjected to the collar 7 limits it and moves down the space, when outer tube 8 continues the Shu Li that the application of forces surpass intermediate plate 62 inner face double wedges 63, and the clamping that is subjected to double wedge 63 after by double wedge 63 is tightened; When outer tube was desired to pull out, belled part 6 was still outwards moved a bit of earlier, and the double wedge 63 engaging-in outer tube epidermises on apparatus inclined-plane make the unexpected slippage of outer tube if the lasting application of force of outer tube is then got profit.Therefore, by belled part 6 outer installment must with the pipe joint 3 mutual chimeric collars 7, not only provide belled part 6 to be able to make up with pipe joint 3 apace, and because belled part 6 can be suitably movable, can be in appropriate moving process after allowing outer tube 8 insert, the engagement of the interior double wedge 62 of outer tube 8 and intermediate plate is more and more tighter, makes outer tube be difficult for slippage.

Shown in Figure 5, another embodiment for pipe joint structure of the present utility model, as shown in the figure, duct ligation head of the present utility model also is formed directly in the head end of filter pipe 100, promptly in the head end of filter pipe 100, form a tubular holding space 4, provide the belled part 6 of the sheathed collar 7 can directly insert use.

It should be noted that at last: above embodiment only in order to the explanation the utility model and and the described technological scheme of unrestricted the utility model; Therefore, although this specification has been described in detail the utility model with reference to each above-mentioned embodiment,, those of ordinary skill in the art should be appreciated that still and can make amendment or be equal to replacement the utility model; And all do not break away from the technological scheme and the improvement thereof of the spirit and scope of model utility, and it all should be encompassed in the middle of the claim scope of the present utility model.
