The beneficial effects of the utility model are：When inserting connecting pipe in water pipeline connector, hold-down ring, which is located at, to be leaned on
The position of nearly housing I, telescopic section outwards expand under the extruding of connecting pipe, facilitate connecting pipe to access circulating line grafting
Groove, after connecting pipe injects circulating line inserting groove, compress direction of the ring telescopic section away from housing I and tighten, extruding is flexible
Section, makes the circular arc connection-peg of a stretchable sheet constantly inject the circular arc inserting groove of another stretchable sheet, so that telescopic section
Constantly inwardly reduce, compress interconnecting tube road.
Brief description of the drawings
Fig. 1 is structural representation of the present utility model.
Fig. 2 is Fig. 1 A-A to sectional view.
Fig. 3 is structural representation when telescopic section is compresses in Fig. 2.
Embodiment
As shown in Figure 1-2, a kind of hydraulic engineering conduit coupling, including housing I 1, being provided at both ends with for housing I 1 are flexible
Section 2, the inner side of telescopic section 1 are provided with circulating line inserting groove 3, and pipeline inserting groove is V-shaped groove, V-shaped groove to the medial recess of housing I,
Telescopic section 2 includes connecting at least two stretchable sheets 4 of pipe, and stretchable sheet is connected with housing I 1；The one end of stretchable sheet 4 is provided with circle
Arc connection-peg 5, the other end are provided with the circular arc inserting groove 6 to match with circular arc connection-peg 5, and circular arc connection-peg 5 is axially long
Degree is equal with the axial length of stretchable sheet 4；The radius of the outer surface of telescopic section 2 increases along away from the direction of housing I 1, is set outside telescopic section 2
There is hold-down ring 7, telescopic section 2 is connected through a screw thread with hold-down ring 7.
Because the length of telescopic section 2 is more than the length of hold-down ring, when inserting connecting pipe, hold-down ring is located at close to housing
