Abstract: Disclosed is a water-sealed and airtight structure for push window, including: one or more water discharge airtight valves embedded in a water discharge conduit at a lower support of a frame, so as to ensure airtight accommodation between the water discharge airtight valves and the water discharge conduit, thereby forming plural pressure-reducing space with outwardly and gradually reducing pressures in the water discharge conduit, thereby eliminating the problem where water accumulated in the water discharging conduit cannot smoothly discharge outwards due to disturbance caused by exterior air pressure. A magnetic strip, such as a soft rubber magnet, is provided to a second rubber strip at an annular edge of the frame. A magnetic attractive strip, such as a metal strip, is provided to an inner face of a corresponding frame of the inner window such that the second strip is able to automatically align and attach in place prior to closing the inner window as a result of the magnetic attraction between the magnetic strip and magnetic attractive strip, thereby eliminating the problem where the inner window may fall or displace due to loading or aging of the rubber strip, resulting in poor seal. A center partition support is affixed to an outer vertical support of a first window of a dual-leaf push window. The outer face of the center partition support outwardly urges against a first rubber strip of the first window, such that a first rubber strip of a second window would urge against the outer face. The end of the inner face is embedded with a water-seal strip against which an inner face of the second window urges. The top and bottom hollow indents are each provided with a stopping plate, such that after tightly closing the first and second windows, the stopping plates would locate between the first rubber strips of the first and second windows and urge against each other to provide water-sealing effect, thereby eliminating the problem where water seepage is easily found at the center partition support in a duel-leaf push window. The first rubber strip is made by a C-shaped rubber strip and is embedded and wrapped in a groove so as to form a circumferential rubber strip so as to eliminate the problem found in the conventional rubber strip made by horizontal supports and vertical supports that are each embedded in the groove and crossed and connected at the intersections thereby easily resulting in water seepage. A biasing roller serves as an urging roller for evenly distributing plural positions and multi-locks, where the biasing degree of the biasing roller can be adjusted so as to accommodate to the mounting plate that has been affixed to the frame, so as to eliminate the problem found in a conventional urging roller of the multi-locks where the inner window cannot be tightly urged against the frame as a result of imprecise alignment placement of the mounting plate of the frame. As such, this invention ensures optimum water-sealed and airtight effects for both single-leaf and dual-leaf push windows.
