In order to achieve the above object, the utility model provides a following technical scheme: including connecting pipe and water pipeling, the connecting pipe inner wall is seted up jaggedly, the breach inner wall is equipped with the internal thread, a rubber circle has been placed on the breach, be equipped with the external screw thread on the water pipeling, the outer parcel of external screw thread has the one deck waterproof tape, set up flutedly on the connecting pipe, be equipped with the lug on the water pipeling, the lug inboard is equipped with the sealing washer, the parcel has the one deck rubber layer on the lug, be equipped with first locking staple bolt on the connecting pipe, be equipped with second locking staple bolt on the water pipeling, accompany sealed clamping ring between first locking staple bolt and the second locking staple bolt, all be equipped with the screw hole on first locking staple bolt and the second locking staple bolt, be equipped with the assorted nut on the bolt.

Preferably, the first locking hoop and the second locking hoop have equal width.

Preferably, the bolts and the nuts are provided with a plurality of groups, and the distance between every two adjacent groups of bolts is equal.

Preferably, the bolt is in a T-shape.

Preferably, the length of the internal thread is two millimeters shorter than the length of the external thread.

The utility model has the advantages that:

through internal thread and external screw thread cooperation connection, and the external screw thread has still wrapped up in the waterproof sticky tape of one deck outward, can prevent to leak, has increased the rubber circle and has strengthened its leakproofness, can make the leakproofness stronger through the cooperation of recess, rubber layer, sealing washer and lug, and its leakproofness has further been strengthened in the cooperation of sealed clamping ring, first locking staple bolt, second locking staple bolt, bolt and nut, if the inner assembly has broken can also dismantle at any time through bolt and nut and change.

FIG. 1 is a schematic structural view of the municipal water supply and drainage engineering pipeline connecting device of the utility model;

FIG. 2 is a top view of the municipal water supply and drainage engineering pipeline connecting device of the present invention;

FIG. 3 is a schematic view of the structural water pipeline of the municipal water supply and drainage engineering pipeline connecting device of the present invention;

in the figure: the water pipe comprises a connecting pipe 1, a water pipe 2, a rubber ring 3, an internal thread 4, a waterproof adhesive tape 5, an external thread 6, a nut 7, a first locking hoop 8, a sealing press ring 9, a groove 10, a convex block 11, a sealing ring 12, a second locking hoop 13, a bolt 14, a rubber layer 15 and a notch 16.

Detailed Description

The technical solution provided by the present invention is clearly and completely described below with reference to the embodiments and the accompanying drawings.

Referring to fig. 1-3, the present invention provides a technical solution: including connecting pipe 1 and water pipeling 2, connecting pipe 1 inner wall is seted up jaggedly 16, breach 16 is seted up at the front end of connecting pipe 1, breach 16 is a circular shape, breach 16 inner wall is equipped with internal thread 4, a rubber circle 3 has been placed on breach 16, rubber circle 3 is placed in the rear end of breach 16, then when the external screw thread 6 of water pipeling 2 was twisted with internal thread 4 cooperation, gradually extrude rubber circle 3, so strengthened its leakproofness, be equipped with external screw thread 6 on the water pipeling 2, the length of internal screw thread 4 is two millimeters less than the length of external screw thread 6, because rubber circle 3 has certain compliance, after through extruding rubber circle 3, internal thread 4 just in time matches with external screw thread 6, external screw thread 6 wraps up one deck waterproof sticky tape 5 outward, waterproof sticky tape 5 can prevent to leak water, strengthen the leakproofness, the recess 10 has been seted up on connecting pipe 1, be equipped with lug 11 on the water pipeling 2, the groove 10 and the bump 11 are matched for use, the inner side of the bump 11 is provided with a sealing ring 12, the sealing ring 12 is made of rubber material, the bump 11 is wrapped by a layer of rubber layer 15, the rubber layer 15 is matched with the bump 11 and the groove 10 for use, the sealing property of the connection between the connecting pipe 1 and the water pipeline 2 is further enhanced, the connecting pipe 1 is provided with a first locking hoop 8, the water pipeline 2 is provided with a second locking hoop 13, a sealing press ring 9 is clamped between the first locking hoop 8 and the second locking hoop 13, the sealing press ring 9 is made of metal rubber material, the first locking hoop 8 and the second locking hoop 13 are both provided with threaded holes, the threaded holes are movably connected with bolts 14, the bolts 14 are provided with matched nuts 7, after connection, the connecting pipe 1 and the water pipeline 2 are further fixed through the mutual matching of the first locking hoop 8, the second locking hoop 13, the bolts 14, the nuts 7 and the sealing press ring 9, thereby can further strengthen its leakproofness, prevent to leak, if inside subassembly has been bad, can dismantle through bolt 14 and nut 7 and change or maintain, first locking is embraced hoop 8 and second locking staple bolt 13 width and is equal, make first locking embrace hoop 8 and second locking staple bolt 13 and can coincide each other, bolt 14 and nut 7 are equipped with a plurality of groups, can be so that connecting pipe 1 and water pipeling 2 have very strong crushing resistance, can prevent like this that the water pressure is too big, and lead to water pipeling 2 and connecting pipe 1 to break or shift, adjacent two sets of bolt 14 intervals equal, bolt 14 is a T font.
