Steel door with anti-seismic function

Abstract

The invention discloses a steel door with an anti-seismic function. The steel door comprises a panel, a sandwich plate and an inner plate, wherein the sandwich plate is arranged between the panel and the inner plate; a first groove is formed in one side, close to the sandwich plate, of the panel; a second groove is formed in one side, close to the sandwich plate, of the inner plate; the outer edge of the inner plate and the first groove are arranged in a press fit manner; an anti-seismic assembly is arranged between the sandwich plate and the second groove; the anti-seismic assembly comprises positioning columns, positioning pins and compression springs; the positioning columns are symmetrically arranged on four groups of outer edges of the sandwich plate; the positioning pins are symmetrically arranged on four groups of inner edges of the second groove; the positioning columns are mounted in the positioning pins in a sliding manner; the compression springs are connected to the outer sides of the positioning pins in a sleeving manner; the anti-seismic assembly is formed by the positioning columns, the positioning pins and the compression springs; before press fit, the positioning pins are inserted into the positioning columns; after the compression springs are completely compressed, press fit is performed; and when the steel door is used, vibration generated during opening and closing or collision is reduced, and the anti-seismic function is realized.

Description

technical field [0001] The invention relates to the technical field of steel doors, in particular to a steel door with an anti-seismic function. Background technique [0002] Steel doors are often used for the entrance and exit of civil protection projects. The classification of civil air defense doors is relatively clear. The door is the door used by the government to mobilize and organize the masses, take anti-airstrike, disaster relief measures, implement rescue and disaster relief activities. [0003] In order to meet the requirements of its own functions, the civil air defense door itself has a large volume and mass, so there will be huge inertia in the process of opening and closing the door, resulting in a large vibration. If there is no buffer and shock absorption, the use of the civil air defense door will be shorten life, and may also cause damage to the wall, therefore, a need for a good cushioning anti-seismic performance of the air defense door.

Problems solved by technology

[0003] In order to meet its own functional requirements, the civil air defense door itself has a large volume and mass, so there will be a huge inertia in the process of opening and closing the door, resulting in a large vibration. If there is no buffer and shock absorption, the use of the civil air defense door will be shortened. service life, and may also cause damage to the wall, therefore, a civil air defense door with good cushioning and earthquake resistance is required
