Description

Technical Field

[0001] The present application relates to the technical field of security doors, and in particular to a reinforcement mechanism for security doors. Background Art

[0002] A security door is a door designed specifically to improve security.

When producing the device, the door body 4 and other reinforcement structures can be produced separately. After the processing is completed, the inner core plate 8 is installed to the inside of the door body 4, so that the limiting block 6 is embedded in the inside of the limiting plate 3, thereby increasing the connection between the inner core plate 8 and the door body 4. Contact area and friction, then fix the fixed plate 1 to the top of the door body 4, screw the fixing bolt 101 between the fixed plate 1 and the door body 4, increase the friction between the fixed plate 1 and the door body 4, and fix the fixed plate 1 to the door body 4, and the fixed plate 1 can limit the inner core plate 8, the reinforcement plate 5, the limit block 6 and the limit plate 3 are all made of aluminum alloy, which is light and has high strength, and has excellent anti-warping performance, which can improve the protection effect at both ends and both sides of the door body 4, the fireproof layer 7 is made of fireproof rock wool material, which has good fireproof performance and improves the fireproof effect of the door body 4, and the inner core plate 8 is made of a synthetic material made of special resin and paper pulp material, which has super compressive strength and further improves the protection effect of the door body 4.

[0021] Reference Figure 4 A bolt hole 402 is provided at the top inside the door body 4, and the fixing bolt 101 is threadedly connected to the bolt hole 402. The staff screws the fixing bolt 101 between the fixing plate 1 and the door body 4 to the inside of the bolt hole 402, increasing the friction between the door body 4 and the fixing plate 1, thereby fixing the fixing plate 1 on the top of the door body 4.

[0022] Reference Figure 4 A limiting groove 301 is provided inside the limiting plate 3, and the limiting block 6 is embedded in the limiting groove 301. When installing the inner core plate 8, the limiting block 6 is embedded in the limiting groove 301, which increases the contact area and friction between the inner core plate 8 and the limiting plate 3, and improves the stability of the installation of the inner core plate 8.
