[0002] The blast-resistant wall can be widely applied to the safety and defense wall, equipment revetment, search area of explosives and contraband, ammunition compound, personnel and material shelter, observation point, defense firing position, highway inspection station, border inspection station and the like. In the application of the blast-resistant wall, it is usually required to arrange a blast-resistant window on the body. In the prior art, the push-pull type window plate is usually used for closing the blast-resistant window. For example, the Chinese utility model patent with the authorization announcement number CN220869235U discloses an automatic blast-resistant window device applied to the blast-resistant wall.

The gap between the blast-resistant window plate and the sealing mounting plate after the blast-resistant window plate is closed is 1-2mm. After the explosion of the explosive in the workshop, the shock wave, fireball and smoke generated by the explosion will leak from the gap around the blast-resistant window, which threatens the personal safety of the operators outside the blast-resistant window and causes certain safety hazards.
