Embodiment
Make specific further instruction to the utility model below in conjunction with the accompanying drawings.A kind of attachment structure of telescopic pipes, bag
Outer tube 1 and inner connecting tube 2 are included, the one end relative with inner connecting tube 2 of outer tube 1 is provided with flange 11, and inner connecting tube 2 docks with outer tube 1
One end be provided with sealing ring 21, sealing ring 21 is built-in with sealing ring 22, nut sleeve 3, inner connecting tube 2 is provided with the outer tube 1
On thread circle 4 and clamp ring 5 are installed, clamping device is provided with described nut sleeve 3 or thread circle 4, clamp ring 5 is clamped in
Between nut sleeve 3 and thread circle 4.
Further：The butt hole 31 of described nut sleeve 3 is more than the external diameter of flange 11, in being provided with outer tube 1
Change 7, the middle holding of change 7 is between the flange of outer tube 1 and the butt hole of nut sleeve 3.
Further：Described middle change 7 is split as more than two valves or two valves, and it is in annulus that assembling is docked during use
Shape.
Further：Described clamp ring 5 be ring-type open annular be split as more than two valves or two valves.
Further：Described clamping device is the locking hole 6 being arranged in nut sleeve 3 or thread circle 4, and locking hole 6 squeezes
Clamp ring 5 is pressed to produce enclasping force inner connecting tube is locked.
Further：Described sealing ring 21 is arranged in seal pipe 8, after inner connecting tube 2 installs thread circle 4, seal pipe 8
Connected as one with inner connecting tube 2, the diameter of seal pipe 8 is more than inner connecting tube 2 and the diameter of bore of thread circle 4.Described seal pipe 8 with
Inner connecting tube 2 is fixed as one.
Expansion tube 9 is additionally provided with described inner connecting tube 2.
Operation principle：During installation, user carries out selecting specific real-time mode according to the actual conditions at scene, such as Fig. 4 institutes
Show, when the butt hole 31 of nut sleeve 3 is more than the external diameter of flange 11, in being installed on the surface of outer tube 1 after change 7, then with nut
The installation of set 3, the middle holding of change 7 serve transfer connection between the flange 11 of outer tube 1 and the butt hole 31 of nut sleeve 3
Mode.This embodiment allows for producer when producing outer tube, without nut sleeve to be installed to after outer bushing surface to enter again
Row flange, facilitate user and carry out selection use.And after producer selects installation nut sleeve, then when carrying out flange, nut sleeve 3
Butt hole 31 is less than the external diameter of flange 11, therefore in docking then without change in installing.
And when inner connecting tube produces, it is necessary to by thread circle behind its surface, reproduction forming seal pipe portion separation structure.
Or tube portion split production will be sealed, seal pipe is attached by scene according to actual conditions with inner connecting tube, the mode of connection
It can use and be spirally connected or weld, form weld seam 81 between the two during welding.Certainly, inner connecting tube sheet also can be used directly in seal pipe
Body, by enlarging machining sealing ring 21 on its cylinder, so as to avoid thread circle and inner connecting tube from releasing.In inner connecting tube and outside
When sleeve pipe docks, the installation sealing ring 22 in sealing ring 21, then sealing tube portion is filled in the inside of outer tube, now sealed
Gap between the filling outer tube 1 of circle 22 and inner connecting tube 2, plays the purpose for preventing leak gas leakage.Then adapter surface is pacified inside
Clamp ring is filled, wherein clamp ring is in open annular, and its section can be in arch type, annular, the various shapes such as rectangle, herein not
It is construed as limiting.Therefore after the position of outer tube and inner connecting tube is adjusted, nut sleeve and thread circle are spirally connected, so as to lock
Circle is fixed therebetween.Wherein, when nut sleeve and thread circle are spirally connected, relative position between the two diminishes, and now, is arranged on
Locking hole 6 in nut sleeve 3 or thread circle 4 mutually extrudes with clamp ring 5, because locking hole can be bellmouth, stepped hole etc.,
It can make it that clamp ring generation enclasping force is locked by inner connecting tube, so as to secure the relative distance of outer tube and inner connecting tube, so as to
When avoiding producing high pressure in pipe, outer tube loosens with inner connecting tube.Therefore it is low with production cost, easy for installation, connection jail
Gu the advantages that reliable, therefore can be widely popularized and be used in various metallic conduits.
The advantages of general principle and principal character of the present utility model and the utility model has been shown and described above.One's own profession
The technical staff of industry is it should be appreciated that the utility model is not restricted to the described embodiments, described in above-described embodiment and specification
Simply illustrate principle of the present utility model, on the premise of the spirit and scope of the utility model is not departed from, the utility model is also
Various changes and modifications are had, these changes and improvements are both fallen within claimed the scope of the utility model.
