Description

Technical Field

[0001] The utility model relates to the technical field of armored doors, in particular to a fireproof and smokeproof sealed armored door. Background Art

[0002] Armored doors are widely used in Europe. Their main feature is that the middle of the door leaf is a solid steel structure (called armored system in China), and the front and back surfaces are covered with a layer of beautiful and easily replaceable finishing materials. The finishing materials can be made of aluminum, copper, glass, composite wood, solid wood, etc. They have many unique advantages and have a stronger protective effect than anti-theft doors. At the same time, based on the non-flammability of the material itself, they also have certain fireproof properties. Combined with the excellent closing effect of the door body itself, they hinder the diffusion of smoke and have a certain fire protection effect.

[0003] However, some of the current anti-theft doors have the same structure as ordinary door bodies, and are connected to the wall panels using a door frame structure. The door frame is directly exposed and is connected to the wall by bolts. When the door frame is directly destroyed, the door structure with extremely strong protective capabilities can be circumvented, and the entire armored door structure can be removed, exposing the door opening.

[0014] 1. Open the frame embedded groove directly on the side wall of the wall door opening, and first use expansion bolts to relatively fix the top frame bar and the bottom frame bar in the embedded groove at the top and bottom of the frame embedded groove, then tilt the two side frame bars so that the connecting groove at the lower end of the side frame bar and the connecting strips at both ends of the bottom frame bar are mutually engaged, and finally rotate the side frame bar so that the connecting groove at the upper end of the side frame bar and the connecting strips at both ends of the top frame bar are mutually engaged, and the expansion bolts are used to relatively fix the connection grooves and the connection between the connection strips, as well as the connection between the side frame bar and the groove structure on both sides of the frame embedded groove, so that the originally exposed The door frame structure connecting the wall and the door structure is completely embedded in the wall at the door opening, and the wall is used to protect the door frame structure, avoiding the possibility of outsiders forcibly dismantling the entire armored door by destroying the door frame, greatly improving the protection capability of the entire armored door. At the same time, the door panel and door frame structure are both made of steel materials, and the sealing structure is made of flame-retardant sealing material, which is combined with the expanded perlite layer to achieve a certain degree of heat insulation effect, so that the entire door structure can be in a sealed state when closed.

Rotate the connecting shaft through the door handle to accumulate elastic potential energy for the coil spring, turn the gear and rub the No. 1 rack and the No. 2 rack to retract the No. 1 and No. 2 bayonet pins into the door panel to achieve the unlocking effect. After the door panel is closed, release the door handle and use the elastic potential energy accumulated by the coil spring to rotate the gear in the opposite direction to pop out the No. 1 and No. 2 bayonet pins and insert them into the buckle grooves at the corresponding positions on the side frame strips to achieve the locking effect. Also install the bayonet structure on the side of the door panel where the hinge is installed to strengthen the connection strength at the hinge between the door panel and the side frame strip to make up for the weak strength of the two metal sheets connected by the hinge alone.
