Improved fire-fighting fireproof door convenient to open and close

Abstract

The invention discloses an improved fire-fighting fireproof door convenient to open and close. The improved fire-fighting fireproof door comprises a door frame, wherein a movable door is arranged on the door frame, and a door closer is connected between the movable door and the door frame. According to the improved fire-fighting fireproof door convenient to open and close, a guide structure can form certain supporting and guiding, the opening and closing smoothness of the movable door is guaranteed, and then the movable door can be opened and closed conveniently; an elastic piece is adopted, so that balls can be in contact with the ground all the time even in an uneven ground environment, and the guiding effect is guaranteed; a blocking structure can quickly descend to seal a gap below themovable door, then the sealing performance is improved, and the smoke isolation effect is enhanced; a display board in an indicating structure can reflect light rays, so that a handle can be quicklyfound under the condition of power failure when a fire disaster occurs, and personnel evacuation is facilitated; and a protective structure is used in cooperation with transparent glass, so that the observation effect is guaranteed, meanwhile, the protection effect can be improved, and the practicability is enhanced.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to an improved fire protection door with convenient opening and closing. Background technique [0002] "Fire protection" is to eliminate hidden dangers and prevent disasters (that is, the general term for preventing and solving the man-made, natural and accidental disasters that people encounter in the process of life, work and study). Fire-fighting fire doors refer to doors that can meet the requirements of fire resistance stability, integrity and heat insulation within a certain period of time. It is a fire-resistant partition with certain fire resistance located in fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. On the door frame, the hinge...

AI Technical Summary

Problems solved by technology

In addition to the function of ordinary doors, fire doors also have the function of preventing the spread of fire and smoke. It can prevent the spread of fire within a certain period of time and ensure the evacuation of people. On the door frame, the hinge bears a large force, which leads to certain limitations in the use of the entire fire door, and after the fire door is installed, there will inevitably be a certain gap underneath. When the fire is released, although it can be effectively Insulate the fire and smoke, but some smoke can penetrate through the gap below, so that the use effect of the fire door is average. In the existing fire doors, there is no structure for indicating the door handle. In the case of fire, Usually, the power is cut off. If it is at night, people cannot find the handle immediately, which is not conducive to the evacuation of personnel. At the same time, the transparent glass structure on the movable door is simple. If there is an explosion in the fire, the explosive may break the transparent glass, thereby endangering the corresponding personnel. safety
