Embodiment

The technical solution of the utility model is further described below in conjunction with accompanying drawing, but described in claimed scope is not limited to.

As shown in Figure 1, Figure 2, Figure 3 shows, a kind of fitting structure easy to assemble, comprise end cap A1, inner end cap 2, pipe box 3, end cap B6 and body 7, described end cap B6 is flexibly connected with body 7, described pipe box 3 is fixed between end cap B6 and body 7, described end cap A1 is flexibly connected with pipe box 3, and described inner end cap 2 is fixed between end cap A1 and pipe box 3; Be provided with seal ring B5 between described pipe box 3 and body 7 surface of contact, to prevent the connecting sewing between pipe box 3 and body 7 from occurring seepage, described seal ring B5 is the sealing of RUBBER O type; In pipe box 3, step end face is provided with seal ring A4, and to prevent from occurring seepage between pipe 8 and pipe box 3, described seal ring A4 is rubbery flat gasket.

Described end cap B6 and body 7 are threaded connection, and described end cap A1 and pipe box 3 are threaded connection, with easy disassembly;

Described inner end cap 2 outer wall is the conical surface, the conical surface is processed with slot to make way 201, and described slot to make way 201 end is arc, ftractures to prevent end; The conical surface is divided into polylith shell fragment 202, described shell fragment 202 is at least 4, to ensure that shell fragment 202 can swing in radial certain amplitude.

The material that described inner end cap 2 adopts is the metallic material that stainless steel or copper etc. have excellent toughness and not easily corrosion, is damaged or corrosion adhesion to avoid it; End cap A1 directly contacts with water etc. with ambient air with end cap B6, therefore selects plastic material, is not easily corroded, if need to change because damaging, replacement cost is also relatively low.

During Product Assembly, as shown in Figure 4, first seal ring B5 is installed in the seal groove on body 7 end face, pipe box 3 and body 7 end face are fitted, pipe box 3 end face also has corresponding seal groove, is pushed down by seal ring B5, is then enclosed within pipe box 3 by end cap B6, tighten with the threaded engagement on end cap B6, pipe box 3 and the sealing between pipe box 3 and body 7 are fixed, end cap A1 and inner end cap 2 bottom surface are set on pipe 8 towards the mouth of pipe of pipe 8 successively, pipe 8 is inserted in pipe box 3, promoting inner end cap 2 by end cap A1 inserts in the gap between pipe box 3 and pipe 8, by the threaded engagement on end cap A1 and pipe box 3, along with end cap A1 tightens gradually, inner end cap 2 is pushed gradually in pipe box 3, the inner end cap 2 of conical surface is subject to the extruding of pipe box 3 inwall, shell fragment 202 front end is shunk gradually, fully contact with pipe 8 outer wall, compress, realize the fixing of pipe 8 and retaining, make pipe 8 end face compression seal circle A4 simultaneously, realize the sealing between pipe 8 and pipe box 3, complete pipe fitting to be connected with pipe 8.When needing dismounting, only need end cap A1 to unscrew, inner end cap 2 resets by shell fragment 202 resilient force and exits, and pipe 8 can be taken out.End cap A1 and end cap B6 outer surface are all processed with radial lines, to increase friction when dismounting, be convenient to firmly turn, being dismounted for multiple times is not fragile, and the operating space needed is very little, easy to use.
