[0019] The utility model will be further described below in conjunction with the accompanying drawings. Figure 1-5 As shown, the utility model provides a double-channel sealed door and window structure, including a window frame 1, a window sash 2 hinged on the window frame 1, a sealing plate 11 is arranged at the rear end of the inner wall of the window frame 1, a sealing strip 12 is attached to the sealing plate 11, an adsorption magnet 13 is arranged in the sealing plate 11, four layers of glass 21 are arranged in parallel on the inner side of the window sash 2, an inert gas layer 22 is arranged between the two outer sheets of glass 21, a sealing component 23 is arranged between the two inner sheets of glass 21, the sealing component 23 includes a PVB interlayer 231, a spacing frame 232 arranged at both ends of the PVB interlayer 231, and a curing sealant 233, and the spacing frame 232 and the curing sealant 233 are connected. The sealants 233 are connected by molecular sieves 234, and both ends of the spacing frame 232 are directly connected to the cured sealant 233. When the window sash 2 is in a closed state, the adsorption magnet in the sealing plate 11 provides adsorption force to tightly adsorb the window sash 2 on the sealing plate 11, and the sealing strip 12 provides the first sealing effect. At the same time, the four layers of glass 21 inside the window sash 2 and the inert gas layer 22 are soundproof and heat-absorbing, and the PVB interlayer 231 is used to seal the inner glass 21. It has the energy-saving effect of hollow glass and the safety advantage of laminated glass, which not only ensures the sealing effect of the glass 21 but also effectively improves the sound insulation and heat insulation capabilities, and is suitable for different application occasions.
