The fittings body is internally provided with dead ring, and the dead ring is socketed with pipeline；External pressure is provided with outside fittings body
Nut, the external pressure nut are threadedly coupled with fittings body；
The dead ring is hollow round table shape structure.
A kind of double sealing quick coupling described in above-mentioned technical proposal, wherein, the upper bottom of the dead ring is arranged on
Inside fittings body, bottom is concordant with the end face of fittings body.
A kind of double sealing quick coupling described in above-mentioned technical proposal, wherein, the dead ring is one or two.
A kind of double sealing quick coupling described in above-mentioned technical proposal, wherein, the end of the docking of the pipeline is set
Put sealing element.
A kind of double sealing quick coupling described in above-mentioned technical proposal, wherein, the sealing element is rubber circle.
A kind of double sealing quick coupling described in above-mentioned technical proposal, wherein, the dead ring is nylon dead ring.
The utility model has the advantages that：
1st, the utility model can be directed to the pipeline of different-diameter and the pipeline of different spatial is attached, and can set
Count out the series of products of the connectors such as elbow, threeway, four-way, reduced pipe；To pipeline maintenance under special occasions, such as pipe crack, pipe
Road is not easy to shift.
2nd, the utility model, which does not need to open screw thread to taken over road in actual use, can be directly connected to various pipelines, and remove
Sealing element plays the role of sealing function, and the end of Outer Tube and dead ring can also play compensation sealing.Therefore, this practicality is new
Type has the characteristics that high-seal, quick connection, and promoting the use of for it can improve working conditions, improve labor efficiency.
Description of the drawings：
1st, Fig. 1 is a kind of structure diagram of double sealing quick coupling of the utility model.
2nd, Fig. 2 is the cross-sectional structure schematic diagram of dead ring in Fig. 1.
3rd, Fig. 3 is applied and the structure diagram in three-way pipe for the utility model.
Figure number explanation：
1st, external pressure nut, 2, sealing element, 3, fittings body, 4, dead ring, 5, pipeline.
Specific embodiment：
To be easy to understand the technical solution of the utility model, below in conjunction with specific embodiments and the drawings to the utility model
Structure and application be further described.
Embodiment 1：A kind of double sealing quick coupling：
A kind of double sealing quick coupling as depicted in figs. 1 and 2, including fittings body 3, dead ring 4, external pressure nut 1
And it is arranged on the sealing element 2 in fittings body 3；The fittings body 3 is internally provided with two dead rings 4, the dead ring 4 and pipeline
5 sockets；External pressure nut 1 is provided with outside fittings body 3, the external pressure nut 1 is threadedly coupled with fittings body 3；The dead ring 4 is
Hollow round table shape structure, the upper bottom of dead ring 4 are arranged on inside fittings body 3, and the bottom of dead ring 4 and the end face of fittings body are put down
Together, the dead ring 4 is nylon dead ring, and the sealing element 2 is rubber circle.
Embodiment 2：A kind of double sealing quick coupling：
When the pipe fitting of the utility model is used for three-way pipe, a kind of double sealing quick coupling as shown in Figure 3,
It needs to be respectively arranged with pipe fitting on the pipeline sealed 5, which includes fittings body 3, dead ring 4, external pressure nut 1 and setting
Sealing element 2 in fittings body 3；Only setting is there are one dead ring 4 for 3 inside of the fittings body, 5 sets of the dead ring 4 and pipeline
It connects；External pressure nut 1 is provided with outside fittings body 3, the external pressure nut 1 is threadedly coupled with fittings body 3；During the dead ring 4 is
Empty round-like structure, the upper bottom of dead ring 4 are arranged on inside fittings body 3, and the bottom of dead ring 4 is concordant with the end face of fittings body 3,
The dead ring 4 is nylon dead ring, and the sealing element 2 is rubber circle.
The use process of the utility model is：Include fittings body 3, tight according to Fig. 1, structure quick coupling shown in Fig. 2
Gu ring 4, external pressure nut 1 and sealing element 2.Pipeline 5 is then twisted by dead ring 4 by the screw thread between external pressure nut 6 and fittings body
Tightly fix.For dead ring according to its inner wall shown in Fig. 2 in Cylinder Surface, outer wall and the fittings body inner wall contacted therewith are in circle
Bore curved surface.Dead ring is pushed to promote inwards when external pressure nut is tightened in this way, at the same time the reduced diameter of dead ring, makes
