and/or the water stop sealing structure comprises a pushing sealing structure, and the pushing sealing structure is configured to prevent water from flowing out through the water flow channel and prevent the water from not entering the anti-seepage structure of the water outlet connecting piece when the opening structure is opened.
8. The novel explosion-proof water-stopping water pipe joint as claimed in claim 7, wherein the pushing part is a convex edge protruding from the outer side of the water movable rod, the explosion-proof water-stopping section is corresponding to one side of the pushing part facing the water outlet end, and the outer diameter of the explosion-proof water-stopping section is smaller than that of the convex edge to form a structure capable of being embedded into the water outlet connecting piece during installation and use;
Or the pushing part is a convex edge of the water movable rod protruding towards the outer side of the end part of the water outlet end;
or the pushing part is the end face of the explosion-proof water stop section facing the water outlet end.
9. A novel explosion-proof water-stopping water pipe joint as claimed in claim 7, wherein the port of the cylinder body facing the water outlet end is internally provided with internal threads for connecting a water connecting piece,
Or the end part of the cylinder body facing the water outlet end protrudes out of the port of the joint pipe body and is provided with external threads for connecting a water outlet connecting piece.
10. The novel explosion-proof water-stopping water pipe joint as claimed in claim 9, wherein the pushing sealing structure is a sealing gasket which is arranged on the pushing part and can be in sealing abutting connection with the end part of the cylinder body facing the water outlet end and the water supply and outlet connecting piece;
Or the pushing sealing structure is that a step edge is formed on the inner side wall of the cylinder body and is abutted with a pushing part when the water stop movable rod moves, and a sealing gasket which can be in sealing abutment with the step edge and the water supply and discharge connecting piece is arranged on the pushing part;
Or the pushing sealing structure comprises a sealing structure in the cylinder between the inner side wall of the cylinder and the water stop movable rod, and the pushing part is provided with a sealing gasket in sealing abutting connection with the water outlet connecting piece.
