Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by a person of ordinary skill in the art without creative efforts belong to the protection scope of the present invention.

The utility model provides a water supply and drainage pipe reducing connecting device, includes flexible coupling pipe 2, and flexible coupling pipe 2 both ends are connected with the external screw thread pipe 1 of intercommunication, and the equal rigid coupling in other one end of two sets of external screw thread pipes 1 has the round platform pipe 4 of fuse, and the outer wall of round platform pipe covers there is one deck sealing layer 41, still including with external screw thread pipe 1 one-to-one can dismantle spiro union complex internal thread section of thick bamboo 5, uses its axis to have clamping screw 6 as central annular array spiro union on the internal thread section of thick bamboo 5.

Furthermore, the outer wall of the external thread pipe 1 is fixedly connected with a clamping block 3, and the clamping block 3 is convenient for driving the external thread pipe 1 to rotate.

Further, the shape of the clamping block 3 is a regular hexagon which is convenient to use in cooperation with a wrench.

Furthermore, the fixing screw rods 6 are provided with at least three groups, and the three groups of fixing screw rods 6 are beneficial to keeping the alignment degree of the water pipe 7 and the axis of the internal thread cylinder 5 when the water pipe 7 is fixed.

Further, the section of the sealing layer 41 is in a semicircular corrugated structure, and the sealing layer 41 in the semicircular corrugated structure is beneficial to improving the sealing performance between the water pipe 7 and the circular truncated cone pipe 4.

The utility model discloses an embodiment:

the flexible connecting pipe 2 can adopt a PVC rubber plastic hose, and the fixed screw 6 adopts an outer hexagon bolt;

the two ends of the soft connecting pipe 2 are connected with external threaded pipes 1 which are communicated with each other, the clamping blocks 3 fixedly connected with the outer walls of the external threaded pipes 1 adopt external hexagonal blocks, and the clamping blocks 3 of the external hexagonal blocks are conveniently matched with a spanner;
