Abstract

The invention relates to a movable door sill electronic control protecting door. The movable door sill electronic control protecting door comprises a door frame and a door sash, a lower door sill is arranged at the lower portion of the door frame, closing locks are arranged both at the upper portion and the lower portion of the door sash, respectively an upper closing lock and a lower closing lock, and are connected with a rotary hand wheel arranged on the door sash surface, hinges are arranged at both the upper portion and the lower portion of one side of the door sash, respectively an upperhinge and a lower hinge, a load bearing arm is arranged between the upper hinge and the lower hinge, the lower door sill is a movable door sill, and the door sash is an arched door sash. The movable door sill electronic control protecting door is stable and reliable to run and high in resistance grade, the lower door sill is flexible and practical, and peacetime and wartime use switching is quick.

Description

technical field [0001] The invention relates to a protective door structure for civil air defense engineering, in particular to an electric control protective door structure. Background technique [0002] The existing electronically controlled protective doors of civil air defense projects have average door leaf resistance levels, and the door leaves are not stable and reliable enough to operate. The lower threshold is a fixed structure, which makes it inconvenient for people and vehicles to enter and exit at ordinary times, and it is troublesome to switch between peacetime and wartime. Contents of the invention [0003] Purpose of the invention: The purpose of the invention is to overcome the deficiencies in the prior art and provide an electronically controlled protective door with a living threshold that operates stably and reliably, has a high level of resistance, flexible and practical lower thresholds, and is quick to switch between peacetime and wartime. [0004] Te...
