Embodiment as shown in figure 1 to figure 13 provides a kind of 600 connection structure of pipe fitting, including connection ontology 100, even
It connects ontology 100 to be arranged in tubular construction, the outer wall of connection ontology 100 is equipped with the first card slot 110, the second card slot 120 and the first card
Position portion 130, the first detent portion 130 are set between the first card slot 110 and the second card slot 120；Shell mounting base 200, shell installation
Seat 200 is arranged in tubular construction, and shell mounting base 200 is equipped with the first mounting portion 210 and the second mounting portion 220, the first mounting portion
210 with the first card slot 110 for being coupled and making shape between the inner wall of shell mounting base 200 and the cell wall of the second card slot 120
At seal chamber；Outer cover body 300, outer cover body 300 are arranged in tubular construction, and outer cover body 300 is equipped with third mounting portion 350,
Third mounting portion 350 be used for the second mounting portion 220 be cooperatively connected and make the inner wall of outer cover body 300 with connect ontology 100
Tightening chamber is formed between outer wall；Seal body 400, seal body 400 are arranged in tubular construction and are set in seal chamber, sealing
The both ends of ontology 400 are respectively equipped with sealing 410 and sealing pressure section 420, and sealing 410 is in around the outer of seal body 400
Wall setting, sealing 410 and sealing pressure section 420 are in the outer wall setting of protrusion seal body 400, sealing pressure section 420
Protrusion height is higher than the protrusion height of sealing 410, and pipe fitting 600 can enter seal chamber via tightening chamber and push sealing originally
Body 400 moves in seal chamber, sealing pressure section 420 is made to compress the first detent portion 130, and sealing 410 can compress pipe fitting 600
Inner wall pipe fitting 600 is sealed；And tightening component, tightening component include the tightening ring 510 intracavitary set on tightening, tightening ring
510 outer wall is equipped with tightening mating surface 511, and tightening mating surface 511 is used to compress cooperation with the inner wall of outer cover body 300, tighten
The inner wall of ring 510 is additionally provided with tightening pressure section 512, and tightening pressure section 512 is in the inner wall setting around tightening ring 510, and tightening is supported
Splenium 512 is used to hold tightly the outer wall of pipe fitting 600.
When pipe fitting 600 is by tightening chamber insertion, pipe fitting 600 pushes seal body 400 to move in seal chamber, due to close
Envelope portion 410 compresses the inner wall of pipe fitting 600 and realizes sealing in protrusion setting, sealing 410, when sealing pressure section 420 compresses
It when the first detent portion 130, can not further push, i.e., pipe fitting 600 protrudes into place；And the tightening mating surface 511 of tightening ring 510 with
The inner wall of outer cover body 300 compresses cooperation and is installed, and the outer wall that tightening pressure section 512 holds pipe fitting 600 tightly avoids pipe fitting 600 loose
It is de-, to realize preferably anti-loose technical effect, and it is not necessarily to special dismantling device, structure is simple, easy to operate.
Embodiment as shown in Figure 2, connection ontology 100 are arranged in tubular construction, and two sides can be connected to, to connect two
Pipe fitting 600 (certainly, as needed, when as plug, the inner cavity of connection ontology 100 is not penetrate through setting), the first card slot 110
Set on position in the inner part, the second card slot 120 is set to by the position of end, and the first detent portion 130 is set to the first card slot 110 and the
Position between two draw-in groove 120, the first detent portion 130 are additionally provided with installation guide cone (the one of close second card slot 120 of guide cone
Side is miner diameter end), during installation for shell mounting base 200, the first card slot 110 can be smoothly slid by installing guide cone
It is interior, later, due to the setting in the first detent portion 130, make shell mounting base 200 that can not retreat abjection, the i.e. slot of the first card slot 110
The first mounting portion 210 of shell mounting base 200 is blocked in wall or the first detent portion 130, thus realize shell mounting base 200 with connect
Installation positioning between ontology 100.
Further, the cell wall of the second card slot 120 be additionally provided with sealing bulge loop 160, sealing bulge loop 160 be equipped at least one,
And around the outer wall setting of connection ontology 100.When pipe fitting 600 pushes seal body 400 to move in seal chamber, bulge loop is sealed
160 further function as the effect for reinforcing sealing, play better seal technical effect；Simultaneously, additionally it is possible to play and avoid water pressure
It is the problem of retreating seal body 400, further to enhance sealing technique effect.
Further, the end for connecting ontology 100 is additionally provided with teeth 150.As shown in Fig. 2, the right side of connection ontology 100
Side end is equipped with the outer circle cyclic structure of outwardly convex, and outer circle cyclic structure is equipped with teeth 150, and teeth 150 is for increasing
Add the rubbing action to 600 inner wall of pipe fitting, prevents pipe fitting 600 from deviating from.
Metal can be used for connection ontology 100 or plastic material is made.
As shown in Figure 4 and Figure 6, the first mounting portion 210 is used for and connect the connection of 100 corresponding matching of ontology, the second mounting portion
220 with third mounting portion 350 for being cooperatively connected (be such as clamped, be fitted and connected), and those skilled in the art can be according to specific
Need to be arranged specific mounting structure, to meet actual installation cooperation needs, which is not described herein again.
Embodiment as shown in Figure 2, the radius of the second card slot 120 are in gradual setting, and close to connection 100 end of ontology
The radius of corresponding second card slot 120 is less than the radius close to corresponding second card slot 120 in 100 middle part of connection ontology.
As shown in Fig. 2, the cell wall section of the second card slot 120 is inclined to set namely the second card slot 120 is integrally conical knot
Structure setting, and the miner diameter end of taper is located at the end side of connection ontology 100.So set, pushing sealing in pipe fitting 600
When ontology 400 is mobile, the radius of connection ontology 100 is become larger, so that the sealing 410 and pipe fitting of seal body 400
It is contradicted between 600 inner wall more and more closely, to realize better seal technical effect.When sealing pressure section 420 encounters the
When the right side wall in one detent portion 130, it can not be advanced further namely pipe fitting 600 is installed in place.
Such as Fig. 3, Fig. 4 and embodiment shown in Fig. 7, shell mounting base 200 is additionally provided at least one peep-hole 230, pries through
Hole 230 is through to the inner cavity of shell mounting base 200, peep-hole 230 and the first detent portion 130 and is arranged in predeterminated position relationship.
As shown in Figure 3 and Figure 4, (namely tubulose) is arranged in hollow cylindrical-shaped structure in shell mounting base 200, can in Fig. 4
To see, the inner circle hole wall 202 of the small interior circular hole of the left end setting of shell mounting base 200, the aperture ratio of small interior circular hole connects
The diameter for connecing 130 corresponding position of the first detent portion of ontology 100 is smaller, to prevent the shell mounting base 200 after installation from taking off backward
Out；The hole wall outer fix of small interior circular hole is additionally provided with sliding tapering 201, convenient for assembly.
As shown in figure 3, shell mounting base 200 is additionally provided with step surface 270, a left side for 270 surrounding housing mounting base 200 of step surface
End setting, is additionally provided with half rotary table 280, and half rotary table 280 is equipped with multiple and cooperates for aligning with outer cover body 300, outer cover body
300 are equipped with semicircle orifice 330 corresponding with half rotary table 280.
As shown in figure 3, peep-hole 230 is set to half rotary table 280.Peep-hole 230 is equipped with multiple and pacifies in spacing surrounding housing
Seat 200 is filled to be arranged.
Such as Fig. 3 to embodiment shown in Fig. 7, shell mounting base 200 is additionally provided with the first clamping portion, and outer cover body 300 is equipped with
