Accompanying drawing explanation
Below in conjunction with accompanying drawing, the utility model is described in further detail:
Fig. 1 is the utility model embodiment overall structure generalized section;
Fig. 2 is the first example structure schematic diagram of the utility model Elastic lock sleeve;
Fig. 3 is the second example structure schematic diagram of the utility model Elastic lock sleeve.
Embodiment
With reference to Fig. 1 ~ Fig. 3, the utility model be the bilateral locking of a kind of snap ring thin metallic tubd pipe between link, comprise the tapered sleeve 3 be sleeved between two pipelines 1 mutually docked, tapered sleeve 3 both ends open and bilateral symmetry are arranged, one end of tapered sleeve 3 is provided with thread section 31 and is positioned at the taper connection section 32 at middle part, is separately provided with the packing nut 4 that is threaded with thread section 31 and the elastic locking be positioned between packing nut 4 and taper connection section 32 overlaps 2 and O RunddichtringO 5.
Between the thin metallic tubd pipe of this snap ring bilateral locking, tapered sleeve 3 is sleeved on after between two pipelines 1 docked mutually by link, advanced by the rotation be threaded between two ends packing nut 4 with thread section 31 on tapered sleeve 3, force elastic locking cover 2 to tighten up and fix two side ducts 1, simultaneously, this link overlaps 2 pairs of pipelines 1 by the elastic locking of ring-type to carry out around anchor ear, contact between itself and pipeline 1 is that face contacts, can effectively improve pipeline connected after anti-pulling ability, and can avoid damaging pipe extrusion.
As the utility model preferred embodiment, elastic locking cover 2 is metal strip shape annulus, and elastic locking cover 2 is provided with one and runs through the elongated opening 21 that elastic locking overlaps 2 total lengths.
As the utility model preferred embodiment, elastic locking cover 2 is stainless steel annulus.
As the utility model preferred embodiment, elastic locking cover 2 is also provided with at least one and overlaps along elastic locking the half long opening 22 that 2 one end extend to the inside.
As the utility model preferred embodiment, half and half long opening 22 is positioned at same one end of elastic locking cover 2.
Elastic locking cover 2 adopts the stainless steel material identical with tapered sleeve 3 with pipeline 1 to make, can effectively avoid in the Long-Time Service process after pipe joint installation, there is electrochemical corrosion between pipeline 1, elastic locking cover 2 and tapered sleeve 3, effectively can extend the working life of pipeline entirety.
Elastic locking cover 2 is preferably set to the ring-type comprising a usual opening 21 and at least one half long openings 22, elastic locking more can be facilitated to overlap the radial uniform shrinkage of 2, thus realize elastic locking cover 2 and reach good face between pipeline 1 outer wall and contact, thus utilize elastic locking to overlap 2 better contractive effects, reach and anchor ear is carried out to pipeline 1, to significantly improve the anti-pull-out property between pipe after link installation.
As the utility model preferred embodiment, one end taper connection section 32 being close to by elastic locking cover 2 be provided with taper connection section 32 inside the taper groove 23 of fitting.
As the utility model preferred embodiment, the inside of packing nut 4 is provided with conical internal cavity 41, and one end that conical internal cavity 41 is close to by elastic locking cover 2 is provided with the packing hipped end mouth 24 of the laminating conical internal cavity gradient.
As the utility model preferred embodiment, the middle part of tapered sleeve 3 is provided with the middle cover pipeline section 33 connecting two ends taper connection section 32, and the internal diameter of middle cover pipeline section 33 is close to the external diameter of pipeline 1.
At the two ends of elastic locking cover 2, taper groove 23 and packing hipped end mouth 24 are set respectively, screwing in the process of packing by packing nut 4, conical internal cavity 41 inside packing nut 4 is along taper groove 23 packing, promote elastic locking and overlap 2 the other ends withstand taper connection section 32 inner side by packing hipped end mouth 24, the two ends pressurized of elastic locking cover 2, and all by compressing component radially, thus elastic locking of being more convenient for overlaps 2 pressurizeds contractions.
Link between pipe relatively in the past, the elastic locking cover 2 arranged in link between this pipe will carry out the form sealed in the past around compressing pipeline by radial locking ring, change the form of face contact anchor ear pipeline into, increase the area of contact between elastic locking cover 2 and pipeline 1, thus increase tension pull out force, to be more conducive between pipe link in the use in building site.
Between this pipe, link is installed by screwing between the packing nut 4 at two ends and thread section 31, and in packing nut 4 precession process, double thread section 31 does not produce the power of outwards support, can avoid producing tapered sleeve 3 destroying.
Certainly, the utility model is created and is not limited to above-mentioned mode of execution, those of ordinary skill in the art also can make equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
