Description

Double-seal pipe joint structure
Technical field
This utility model is related to a kind of pipe joint structure, and more particularly, to a kind of connection is reliable, good airproof performance, easy disassembly Double-seal pipe joint structure.
Background technology
Pipe joint is connecting line or pipeline is contained in part on Hydraulic Elements in hydraulic system, is a kind of to lead in fluid The general name of the connector of Lu Zhongneng assembly and disassembly.Typically mainly include:Three kinds of structures such as welding type, bite type and flared type, therein Ferrule-type compression joint is generally applicable to the non-aggressives such as Oil, Water, Gas or Korrosionsmedium, the rule of sealed fitting adapted aluminium-plastic pipe Lattice require relatively flexibly, to be widely adopted in the systems such as oil refining, chemical industry, light industry, weaving, national defence, metallurgy, aviation, ship, It is applied to the hydraulic drive pipeline such as various mechanical engineerings, machine tool.But existing ferrule-type compression joint generally existing junction Sealing ring is easy to wear, leads to sealing poor, the technical problem such as service life is short.
Content of the invention
This utility model mainly there is provided a kind of connection reliability, good airproof performance, high yield rate, the double containment of easy disassembly Pipe joint structure, it is easy to wear to solve junction sealing ring present in prior art, leads to sealing poor, service life is short, The technical problem that dismounting is wasted time and energy etc..
Above-mentioned technical problem of the present utility model is mainly addressed by following technical proposals:A kind of doubly-closed tube Joint design, including pipe joint body and be docked at connecting tube on two ports of pipe joint body, described connecting tube extends to In the port of pipe joint body, pipe joint body port corresponding with connecting tube inner ring surface is at least embedded with two O shapes side by side Sealing ring, O-ring seals swelling is between the mating surface of connecting tube and pipe joint body, and is set with outside the port of pipe joint body Have card cap, connecting tube corresponding with card cap be set with claw, claw be clamped and connected pipe and interworking be connected in card cap.By The inner ring surface of pipe joint body port is at least embedded in two O-ring seals, when one of O-ring seals occur to lose efficacy, O-ring seals are at least also had to can guarantee that the positive sealing between pipe joint body and connecting tube, therefore sealing reliability is high, makes Use life-span length;Clamp connecting tube by card cap crimp jaws, connected mode is simple and reliable, buckle-type connects, easy accessibility.
Preferably, being provided with counterbore in the port of described pipe joint body, O-ring seals are side by side in counterbore.O shape is close Seal is inlaid in counterbore, prevents O-ring seals from deviating from, fixed form is simple and reliable.
Preferably, being provided with outer dop, the outer ring surface of pipe joint body on the corresponding inner ring surface of described card cap medial extremity On be correspondingly provided with annular slot, outer dop slides and is connected in annular slot, card cap outboard end along pipe joint body end face and Inner ring surface extends several inner clip heads of formation inwardly downward, and inner clip head is connected on claw.Card cap passes through outer dop and pipe joint Annular slot interworking on body, inner clip head again with claw interworking, structure is simple, easy accessibility.
Preferably, described claw includes the collar being sleeved in connecting tube that slides, in the set towards connecting tube opening Stretch out on ring end face several ratchets of formation, and card cap compresses ratchet and is inwardly clamped in connecting tube.Claw is active some Connecting tube is clamped, fixed form is simple and reliable after individual ratchet deformation.
Therefore, a kind of Double-seal pipe joint structure tool of the present utility model has the advantage that:1st, using double O-ring seals, Reduce the water leakage ratio of pipe joint, good airproof performance;2nd, adopt inner blocking type structure to connect, without ultrasonic bonding, improve production effect Rate, reduces production cost;3rd, no ultrasound wave welding slag and rosin joint phenomenon, improves the qualification rate of production.
Brief description:
Fig. 1 is a kind of structural representation of this utility model Double-seal pipe joint structure.
Specific embodiment:
Below by embodiment, and combine accompanying drawing, the technical solution of the utility model is described in further detail.
Embodiment:
As shown in figure 1, a kind of Double-seal pipe joint structure of the present utility model, the pipe joint body 1 including L-shaped and docking Connecting tube 2 on 1 two ports of pipe joint body, connecting tube 2 extends in the port of pipe joint body 1, in pipe joint originally The port of body 1 has counterbore 6, is embedded with two O-ring seals 3 side by side, O-ring seals 3 swelling is in connecting tube 2 in counterbore 6 And between the mating surface of pipe joint body 1, it is set with card cap 4 outside the port of pipe joint body 1, connecting tube 2 corresponding with card cap 4 On be set with claw 5, claw 5 is clamped and connected pipe 2 and interworking is connected in card cap 4, on the corresponding inner ring surface of card cap 4 medial extremity Level extends inwardly to form outer dop 7, and on the outer ring surface of pipe joint body 1, correspondence has annular slot 8, and outer dop 7 slides and blocks Be connected in annular slot 8, card cap 4 outboard end along the end face of pipe joint body 1 and inner ring surface extend inwardly downward formation several Inner clip head 9, claw 5 therein includes the collar 51 being sleeved in connecting tube 2 that slides, in the collar towards connecting tube 2 opening Stretch out on 51 end faces several ratchets 52 of formation, and the inner clip head 9 on card cap 4 compresses the inside resilient clamp of ratchet 52 and connecting On pipe 2.
Specific embodiment described herein is only to design of the present utility model explanation for example.This utility model Person of ordinary skill in the field can make various modifications or supplement or adopt class to described specific embodiment As mode substitute, but without departing from of the present utility model spirit or surmount scope defined in appended claims.
