Description
Technical field
The utility model is a kind of pipeline fast joint structure.
Background technique
Along with the development of national economy, every infrastructure obtains unprecedented development, the living standard of the various places people obtains and further develops, and directly results in the energy demand that people are growing like this, comprising: the various life basic power source such as rock gas, transmit these energy, need from origin tubing, transmitted by pipeline, send to destination, in this case, can the height of pipe laying efficiency determine the key point that solve energy demand problem as early as possible.
Existing for carrying the pipeline of Gas Energy Source, owing to producing the restriction with transport, be generally the pipeline being connected into sufficient length between multiple tracheae by joint, joint there is loose joint nut, for fixing with being spirally connected of tracheae, described joint is generally two-way or threeway, need to ensure absolute tightness and splicing firm reliability between tracheae and joint, but the join strength between existing this kind of tracheae and joint is not enough, installation efficiency is low, and tracheae comes off the potential safety hazard such as Leakage Gas existed.
Summary of the invention
It is low that the utility model will solve connection efficiency between existing tracheae and joint, the technical problem of join strength deficiency.
The technical scheme in the invention for solving the above technical problem is:
The utility model discloses a kind of pipeline fast joint structure, comprise tracheae, adaptor tube and locking bed, tracheae passes the center hole on locking bed and realizes removably connecting by the screw threads for fastening of locking bed and adaptor tube, stretch at locking bed between the bulge loop on the end face of adaptor tube and adaptor tube inner ring and be provided with slotted collar, described bulge loop inner ring is provided with the annular slope A extended out, described slotted collar and bulge loop fit one side outer ring be provided with the annular slope B matched with annular slope A; Locking bed and adaptor tube be spirally connected screw time, locking bed extruding slotted collar, the annular slope B of annular slope A to slotted collar of bulge loop inner ring has a relative active force, and impel slotted collar compress and be thoroughly placed in annular slope A, the inner wall tightening of slotted collar lives tracheae.
The inner ring of described slotted collar is provided with at least two ring shape locking latches, described locking latch indentation.
Preferably, described locking latch is elastic steel sheet.
Described locking bed center-hole diameter is less than the race diameter of slotted collar.
The bulge loop inner ring of described adaptor tube is also provided with circular groove, and circular groove is built with seal ring.
Opening is in time closed upon compression for described slotted collar, and the diameter of slotted collar inner ring is less than the external diameter of tracheae, and the height of annular slope B is more than or equal to the height of annular slope A.
The technique effect that the utility model can reach is:
Compared with prior art, pipeline fast joint structure of the present utility model, by screwing locking bed, give slotted collar an extruding force, then by the cooperation of annular slope, the extended distance of slotted collar is slowly diminished, thus make the external diameter of the internal diameter of slotted collar and tracheae more and more close, finally realize the resistance to tracheae by locking latch, principle is simple, easy to operate, installation efficiency is high.
Accompanying drawing explanation
Fig. 1 is the structural representation of the utility model pipeline fast joint structure;
Fig. 2 is the three-dimensional exploded view of the utility model pipeline fast joint structure.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Refer to Fig. 1, Fig. 2, the utility model provides a kind of pipeline fast joint structure, comprise tracheae 1, adaptor tube 2 and locking bed 3, tracheae 1 passes the center hole 4 on locking bed 3 and realizes removably connecting by the screw threads for fastening of locking bed 3 with adaptor tube 2, stretch at locking bed 3 between the bulge loop 5 on the end face of adaptor tube 2 and adaptor tube 2 inner ring and be provided with slotted collar 6, described bulge loop 5 inner ring is provided with the annular slope A7 extended out, and described slotted collar 6 and bulge loop 5 outer ring simultaneously of fit is provided with the annular slope B8 matched with annular slope A7; Locking bed 3 and adaptor tube 2 be spirally connected screw time, locking bed 3 extrudes slotted collar 6, the annular slope B8 of annular slope A7 to slotted collar 6 of bulge loop 5 inner ring has a relative active force, impel slotted collar 6 compress and be thoroughly placed in annular slope A7, the inner wall tightening of slotted collar 6 lives tracheae 1.
The inner ring of described slotted collar 6 is provided with at least two ring shape locking latches 9, described locking latch 9 indentation.
Preferably, described locking latch 9 is elastic steel sheet.
Described locking bed 3 center hole 4 diameter is less than the race diameter of slotted collar 6.
Bulge loop 5 inner ring of described adaptor tube 2 is also provided with circular groove, and circular groove is built with seal ring 10.
Opening is in time closed upon compression for described slotted collar 6, and the diameter of slotted collar 6 inner ring is less than the external diameter of tracheae 1, and the height of annular slope B8 is more than or equal to the height of annular slope A7.
Below use principle of the present utility model is made an explanation:
The utility model, when assembling, first, will be embedded in the circular groove of bulge loop 5 inner ring in seal ring 10, secondly, slotted collar 6 is inserted bulge loop 5 end face of adaptor tube 2, annular slope A7 and annular slope B8 is matched, finally, locking bed 3 and adaptor tube 2 are spirally connected.
When using splicing, screw-thread fit between locking bed 3 and adaptor tube 2 is in relaxation state, then, tracheae 1 is inserted from locking bed 3 center hole 4, tracheae 1 end extends to seal ring less than 10, then locking bed 3 is screwed, there is an extruding force end that locking bed 3 is in adaptor tube 2 to slotted collar 6 exterior edge face, slotted collar 6 is impelled to move vertically and in radial contraction, along with constantly screwing of locking bed 3, the internal diameter of slotted collar 6 is constantly reduced, until locking latch 9 blocks tracheae 1, and tracheae 1 can not be extracted easily, it is namely standard assembling condition.
Pipeline fast joint structure of the present utility model; locking latch 9 has very high join strength with coordinating of tracheae 1; effectively avoid tracheae 1 dropping situations caused because tracheae 1 internal air pressure is too high to occur, add Security, protect civic personal safety as well as the property safety.
Above a kind of pipeline fast joint structure that the utility model embodiment provides is described in detail, apply specific case herein to set forth principle of the present utility model and mode of execution, the explanation of above embodiment is just for helping to understand the technological scheme that the utility model discloses; Meanwhile, for one of ordinary skill in the art, according to thought of the present utility model, all will change in specific embodiments and applications, in sum, this description should not be construed as restriction of the present utility model.
