the method comprises the steps of selecting a first conversion joint 4 and a first flange 5 which are matched according to the size of an output end of a drainage hose needing to be communicated, connecting the first conversion joint 4 to one end, back to the locking sub-base 1, of the receiving female base 2, connecting the first flange 5 to one end, back to the receiving female base 2, of the first conversion joint 4, selecting a second conversion joint 6 and a second flange 7 which are matched according to the size of an input end of a water pump needing to be communicated, connecting the second conversion joint 6 to one end, back to the receiving female base 2, of the locking sub-base 1, and connecting the second flange 7 to one end, back to the locking sub-base 1, of the second conversion joint 6. In the process of connecting the locking sub-base 1 and the receiving female base 2, the inner insertion tube 13 is inserted into the receiving female base 2, the clamping plate 11 is aligned with the access hole 22 formed in the end face of the receiving female base 2 and inserted into the clamping groove 21, the locking sub-base 1 is rotated according to the direction indicated by the guide sign 24, the clamping plate 11 rotates in the same direction in the clamping groove 21, after the locking sub-base rotates to a set position, the clamping plate 11 abuts against the limiting plate 15, and the clamping plate 11 and the clamping groove 21 complete clamping connection. In the process of rotating the clamping plate 11 in the clamping groove 21, the clamping plate 11 gradually approaches the positioning element 34 penetrating through the second positioning hole and entering the clamping groove 21, and continues to rotate after contacting the positioning element 34, so as to apply an extrusion force to the positioning element 34 to force the positioning element to exit the second positioning hole, so that the positioning element 34 drives the limiting element 33 fixedly connected with the positioning element to move in a direction away from the second positioning hole under the action of the extrusion force, and the elastic element 32 fixedly connected with the limiting element 33 is extruded in the moving process, so that the elastic element 32 is further compressed to generate a larger elastic potential energy, and the positioning element 34 exits the second positioning hole, when the clamping plate 11 continues to rotate to a set position in clamping connection with the clamping groove 21, the first positioning hole 12 on the clamping plate 11 is arranged corresponding to the second positioning hole, at this time, the snap plate 11 does not apply an extrusion force to the positioning element 34, and the elastic element 32 applies an external force to the positioning element 34 in the process of recovering deformation, so that the positioning element 34 sequentially penetrates through the second positioning hole and the first positioning hole 12, and then the positioning element 34 blocks the snap plate 11 to continue rotating, so that the snap plate 11 is further limited, that is, the locking sub-base 1 and the receiving female base 2 are further limited. When water flows through the bearing female seat 2 and the locking sub-seat 1, the connection position of the inner inserting tube 13 and the inner wall of the bearing female seat 2 is sealed by means of the butt joint of the sealing ring 23 arranged on the inner wall of the bearing female seat 2 and the end face of the inner inserting tube 13 and the butt joint of the sealing ring 14 circumferentially arranged on the inner inserting tube 13 and the inner wall of the bearing female seat 2, and impurities in the water flow are filtered by means of the filtering plate 17 arranged on the inner wall of the locking sub-seat 1, so that the water pump is prevented from being abraded.

Adopt the utility model discloses water pump pipeline connecting device utilizes joint board 11 with the joint in chucking groove 21 is connected, and joint board 11 with when chucking groove 21 joint is connected to the set position, positioning element 34 among the auxiliary positioning subassembly with joint board 11's connection realizes right joint board 11's dual spacing, also realizes promptly accept female seat 2 with the dual spacing of relation of connection between the locking sub-seat 1 prevents the operation in-process accept female seat 2 with it is not hard up to appear in the connection between the locking sub-seat 1, has improved the stability of relation of connection between the two.

Finally, it should be noted that: the above embodiments are only used to illustrate the technical solution of the present invention, and not to limit the same; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art will understand that: the technical solutions described in the foregoing embodiments may still be modified, or some technical features may be equivalently replaced; such modifications or substitutions do not depart from the scope of the invention in its corresponding aspects.
