Model utility content
The utility model is for the deficiency of above-mentioned technology, provides that a kind of cost of production is lower, favorable sealing property, easy-to-dismount pipe coupling.
For reaching above-mentioned target, the technical solution adopted in the utility model is: a kind of pipe coupling easy to assemble, comprises body, seal member, takes over the compositions such as snap ring, intubate and seal snubber, snap ring snubber; The inner wall of end of described body is provided with ring-shaped step, lays seal member on step, and sealing body member is divided into seal leading portion and seal back segment, by seal snubber restriction fixed position; Seal leading portion is the rubber turn that is provided with the circular-arc inner side surface of convex, the rubber turn that seal back segment is trapezoid cross section, and the delta-shaped region of trapezoid cross section bottom position hollows out processing; Body front end position is provided with adapter snap ring, and this adapter snap ring consists of card base and claw, and card base is fixing by the restriction of snap ring snubber, and claw tilts towards taking over direction of insertion; Snap ring snubber and body are fixed by socket, for limiting the fixing position of taking over snap ring; Body end is also provided with intubate, and when pressing this intubate in body, the front end of intubate can strut the claw of taking over snap ring.
Seal member in the utility model structure comprises that the rubber turn seal leading portion and the bottom position delta-shaped region that are provided with the circular-arc inner side surface of convex pass through the trapezoid cross section rubber turn seal back segment that hollows out processing, as preferably, the diameter of bore of described seal leading portion rubber turn is slightly larger than the diameter of bore of seal back segment rubber turn.
As preferably, described body can be fluid pipeline, can be also the devices such as gas pipeline.
While using the utility model, will take over and insert in body, and take over front end and can strut the claw of taking over snap ring, claw is issued to and blocks the effect of taking over outer wall in elastic restoring force effect, realizes taking over being communicated with the quick of body; Now, the rubber turn seal back segment of trapezoid cross section seals as first, under the effect of the inner side surface of its trapezoid cross section rubber turn hydraulic pressure in body, especially bottom position delta-shaped region in trapezoid cross section is through hollowing out after processing, the tube wall that makes the inner side surface of seal back segment rubber turn and insert to take over contacts more tight, and the extruding force between surface of contact is along with the rising meeting of hydraulic pressure in body strengthens gradually; The seal leading portion that is provided with the rubber turn of the circular-arc inner side surface of convex seals as second, and the inner side surface of rubber turn is forming large size close contact, good seal performance under squeezing action mutually with the tube wall that inserts adapter; When needs dismounting is taken over, intubate to be pressed in body, intubate just can strut the claw of taking over snap ring, takes over snap ring and has just unclamped adapter outer wall, both can by taking over, extract out easily.
By by seal member designs being the rubber turn seal leading portion of the circular-arc inner side surface of convex and the trapezoid cross section rubber turn seal back segment that bottom position delta-shaped region process hollows out processing, two seals is provided, guaranteed the sealing of taking over, and whole seal member is as an accessory, reduce cost of production, simplified assembling procedure.
As preferably, on described inboard wall of tube body and seal snubber, snap ring snubber outer side surface, be respectively arranged with specification matches, position is corresponding groove and projection, to realize both being fixed by socket; On described snap ring snubber inner side surface and intubate outer side surface, be respectively arranged with specification matches, position is corresponding step and barb angles, prevent that intubate from use skidding off.
Compared with prior art, the remarkable advantage of the pipe coupling easy to assemble that the utility model provides is: the utility model is by being to comprise being provided with the rubber turn seal leading portion of the circular-arc inner side surface of convex and bottom position delta-shaped region through hollowing out the trapezoid cross section rubber turn seal back segment of processing by seal member designs, two seals is provided, guaranteed the sealing of taking over, and whole seal member is as an accessory, reduce cost of production, simplified assembling procedure.
Accompanying drawing explanation
Fig. 1 is pipe joint structure cross-sectional schematic of the present utility model.
Wherein: 1 is body, 2 is step, and 3 is seal member, and 4 is seal snubber, and 5 is snap ring snubber, and 6 is intubate, and 7 for taking over snap ring, and 31 is seal back segment, and 32 is seal leading portion.
Embodiment
Be below specific embodiment of the utility model by reference to the accompanying drawings, the technical solution of the utility model is further described.
Consult accompanying drawing, the pipe coupling a kind of easy to assemble that the utility model provides, comprises body 1, and seal member 3 is taken over snap ring 7, intubate 6 and seal snubber 4, snap ring snubber 5 members such as grade.Described body 1 can be a conduit pipeline, can be also that body described in the present embodiment 1 is right-angled bend joint for being communicated with the conduit pipeline devices such as the joint of two conduit pipelines or water tap, valve.
During concrete enforcement, the inner wall of end of body 1 is provided with ring-shaped step 2, on step 2, install seal member 3 is set, described seal member 3 is divided into seal leading portion 32 and seal back segment 31, seal leading portion 32 is for being provided with the rubber turn of the circular-arc inner side surface of convex, the rubber turn that seal back segment 31 is trapezoid cross section, and trapezoid cross section bottom position delta-shaped region is through hollowing out processing.
For fixed constraints is inserted the adapter in body 1, described body 1 front end position is also provided with takes over snap ring 7, takes over snap ring 7 and consists of card base and claw, and card base is fixing by 5 restrictions of snap ring snubber, and claw tilts towards taking over direction of insertion.
In concrete enforcement, on body 1 inwall and seal snubber 4, snap ring snubber 5 outer side surfaces, be respectively arranged with specification matches, position is corresponding groove and projection, to realize both being fixed by socket.
In concrete enforcement, when pressing intubate 6 in body 1, the front end of intubate 6 can strut the claw of taking over snap ring 7; On snap ring snubber 5 inner side surfaces and intubate 6 outer side surfaces, be respectively arranged with specification matches, position is corresponding step and barb angles, prevent that intubate 6 from use skidding off.
While using the utility model structure, will take over and insert in body 1, and take over front end and can strut the claw of taking over snap ring 7, claw is issued to and blocks the effect of taking over outer wall in elastic restoring force effect, realizes taking over being communicated with the quick of body 1; Now, the rubber turn seal back segment 31 of trapezoid cross section seals as first, under the effect of the inner side surface of its trapezoid cross section rubber turn hydraulic pressure in body, especially bottom position delta-shaped region in trapezoid cross section is through hollowing out after processing, the tube wall that makes the rubber turn inner side surface of seal back segment 31 and insert to take over contacts more tight, and the extruding force between surface of contact is along with the rising meeting of hydraulic pressure in body strengthens gradually; The seal leading portion 32 that is provided with the rubber turn of the circular-arc inner side surface of convex seals as second, and the inner side surface of rubber turn is forming large size close contact, good seal performance under squeezing action mutually with the tube wall that inserts adapter.When needs dismounting is taken over, intubate 6 to be pressed in body 1, intubate 6 just can strut the claw of taking over snap ring 7, takes over snap ring 7 and has just unclamped adapter outer wall, both can by taking over, extract out easily.
