Specific implementation mode
Below in conjunction with the accompanying drawings and specific embodiment the utility model is described in further detail.
As shown in Figs. 1-2, the telescoping tube include include more be nested together, the tube body 1 that diameter is sequentially reduced, the tube body
1 is stainless steel tube.Stainless steel tube lighter in weight, and have preferable bending and torsional strength, be widely used in oil, chemical industry,
The conveyance conduits such as medical treatment, video, light industry, machinery instrument and machine structural parts etc..Two-phase is socketed small interior of diameter in tube body 1
Tube wall is equipped with convex position-arresting ring 2, and the position-arresting ring 2 is integrally formed with tube body 1, so can be improved whole strong
Degree, effectively prevent the section that position-arresting ring 2 is contacted with tube body 1 cracking and influences normal use.And it is straight in two-phase socket tube body 1
The big outer tube body end point of diameter, which is equipped with, can abut the meeting device 3 of position-arresting ring 2, interior tube body from skidding off from outer tube body preventing and
Inside and outside tube body is set to detach.
The meeting device 3 includes the abutting boss for being fixedly attached to outer tube body end point, the abutting boss and inner tube
It is equipped with gap between body, and on abutting the boss separate end face abutted against with position-arresting ring 2 and close to being equipped with annular at interior tube body
Slot 6 is embedded with sealing ring 7 in the annular groove 6, i.e. the internal diameter of sealing ring 7 and the outer diameter of interior tube body is identical, sealing ring 7 it is outer
Diameter is identical as the outer diameter of annular groove 6, and so then the inner peripheral surface of sealing ring 7 is in contact with the tube wall of interior tube body, and sealing ring 7 is outer
Circumferential surface is in contact in the side wall of annular groove 6, thus sealing ring 7 can effectively ensure that the leakproofness between two-phase socket tube body 1.
Wherein, it includes the ring set 4 that ring is located on outer tube body outer wall to abut boss, and the annular being connect with 4 one end of ring set
Boss 5, and the annular convex platform 5 and ring set 4 are integrally formed, and integral strength so can be improved, effectively prevent annular convex platform 5 with
The section that ring set 4 contacts is cracking and influences normal use.Gap is equipped between the annular convex platform 5 and interior tube body, this is empty
Gap is to abut the gap being equipped between boss and interior tube body.4 inner wall of the ring set is equipped with internal thread, and leans on proximal end in outer tube body
Outer wall at head is equipped with external screw thread, and the internal thread can be screwed with external screw thread.Thus ring set 4 can be bolted in outer tube body end
Place can facilitate carry out fast assembling-disassembling between abutting boss and outer tube body in this way, in order to carry out the later stage to more tube bodies 1 of socket
Maintenance and the replacement to tube body 1.
Further, the sealing ring 7 is fixed on through fixed ring 8 in annular groove 6.In the fixed ring 8 with sealing ring 7
Contact position is equipped with the annular flange 9 for being squeezed sealing ring 7, close when annular flange 9 squeezes sealing ring 7
Seal 7 can be squeezed into being expanded such that far from pressure direction in the gap between abutting boss and interior tube body, to realization pair
The closure in gap, thus the leakproofness between two-phase socket tube body 1 can be effectively improved.And be squeezed and 7 energy of sealing ring that expands
Enough provide axial direction larger frictional force, therefore the position of two adjacent tubes 1 can be also relatively fixed.The annular flange
9 are integrally formed with fixed ring 8, so set, integral strength can be improved, effectively prevent what annular flange 9 was contacted with fixed ring 8
It cracks and influences normal use in end face.
The fixed ring 8 is attached by bolt 10 with boss is abutted.In this way, be not only convenient for fixed ring 8 with abut it is convex
Dismounting between platform, in order to later maintenance；Meanwhile ring 8 is fastened and fixed by bolt 10 and abuts boss, it can also adjust fixation
Ring 8 with abut the relative position between boss, to realize that annular flange 9 in fixed ring 8 can generate different squeeze to sealing ring 7
Pressure, to realize better seal effect.
The bolt 10 is constituted by bolt head and with the integrally formed screw rod of bolt head, screw rod outer surface shape
It is equipped with colloid layer at having external screw thread, the external screw thread.The setting of the colloid layer, can be in bolt 10 and the spiral shell abutted on boss
When pit coordinates, colloid layer is filled between screw rod and the gap of threaded hole, can so be increased bolt 10 and be abutted between boss
Frictional force and start bolt 10 needed for driving force, so can effectively prevent bolt 10 loosen and fall off, make bolt 10 connect
Fixed ring 8 with to abut boss more solid and reliable.Wherein the specific thickness of colloid layer coordinates with the diameter of screw rod and with screw rod
Threaded hole size and determine, if because the thickness of colloid layer is blocked up, cause screw rod cannot with threaded hole realize screw-thread fit；
And if the thickness of colloid layer is excessively thin, after rotary screw colloid layer be not enough to filling screw rod and threaded hole between gap, then
Loosen, anticreep effect it is poor.
In addition, the sealing ring 7 is woven by expanded graphite line, sealing ring 7 so may make to can be used for boiling water, height
The media such as temperature, high steam, heat transferring medium, oils, acid, alkali, hydrogen, ammonia, organic solvent, hydrocarbon, cryogenic liquid, make
With in extensive range, and because sealing ring 7 is woven using expanded graphite line, so sealing ring 7 can reach sealing effect with " labyrinth effect "
Fruit.
The telescoping tube of the utility model when in use, two-phase be socketed tube body 1 in outer tube body can by meeting device 3 with it is interior
The relative position of tube body is fixed, and the position-arresting ring 2 on interior tube body outer wall can prevent interior tube body when being stretched out from outer tube body
And it is detached with outer tube body；When needing to carry out scaling operation to interior tube body and outer tube body, it is only necessary to unscrew bolt 10, so that annular
Flange 9 no longer squeezes sealing ring 7, then sealing ring 7 is resilient, the frictional force for the axial direction that such sealing ring 7 generates
Reduce, so interior tube body can carry out scaling operation with respect to outer tube body；When scaling operation completion, fixed ring 8 is consolidated by bolt 10
It is scheduled on and abuts on boss, and tighten bolt 10, so that the annular flange 9 in fixed ring 8 again squeezes sealing ring 7, squeeze
The sealing ring 7 of pressure is squeezed into after expanding in the gap abutted between boss and interior tube body, to make two tube bodies 1 to socket-connect realize compared with
Good leakproofness, while the position of two socket tube bodies 1 can also be relatively fixed.The telescoping tube is easy to operate, light, square
Just, fast, and it is simple in structure, assembly is quick, and good seal performance, there is the very strong market competitiveness, can be widely applied for
Industrial production.
The foregoing is merely the preferred embodiment of the utility model, but the scope of protection of the utility model is not limited to
This, any technical person familiar with the field within the technical scope disclosed by the utility model, technology according to the present utility model
Design is subject to the technical solution obtained by equivalent substitution or change, should all be covered by the scope of protection of the utility model.
