The present invention relates to an electric sliding crimped airtight door, and more particularly, by automatically driving the airtight door to be installed for the purpose of protecting personnel and facilities in a building that requires the blocking of chemical agents or other confidentiality in the NBC situation. An electric sliding crimp airtight door that can be locked or unlocked.

In general, confidential doors are installed in places such as buildings that require the protection of chemical agents or other confidentiality from the NBC, to protect people and facilities inside the building by blocking air from outside.

Since the NBC situation or the inside of a building requiring confidentiality generally forms a positive pressure with a higher air pressure than the outside of the contaminated air, the air moves from the inside of the facility to the outside.

Thus, the airtight door is installed so that the airtight door can be closed outward from the inside of the air flow direction.

On the contrary, in the case of the building where the negative pressure is formed, the door is installed so that the door can be closed from the outside to the inside.

In the case of existing secret doors, if the exterior of the building is contaminated, positive pressure is generated inside the building, which closes the secret door.

At this time, the inside of the building should monitor and control the access of external personnel, conventionally, there was a problem that can be opened from the outside because the lock of the secret door is installed outside the facility.

In addition, in the case of the conventional hermetic door, the locking device is installed on the door, and when the handle is rotated, the flat car is rotated together, and the rotary motion is converted into a linear motion up and down through the rack gear. Is converted back into rotational motion.

And when the locking body is rotated by 90 ° by the rotational movement is installed in the door frame of the airtight door is locked up the inclined portion of the lock groove formed in the inclined portion acting as a wedge to lock the airtight door.

However, when locking the airtight door by rotating the lock body by rotating the handle 90 ° by conventional handle, there is no means to fix the lock body when the lock body reaches 90 °, so the lock body flows down to open the airtight door and is not compressed. As a result, airtightness was insufficient.

In addition, when the locking body rotates on the inclined portion of the locking groove, the cross-sectional area of the locking groove is not wide, so the locking of the door is not perfect, and when the flat car is slightly misaligned, the door fails.

In addition, the conventional hermetic door cannot be controlled remotely because the secret door is locked or unlocked by turning the handle by human force.

The present invention has been made to solve the above problems, and automatically lock the airtight door to be installed for the purpose of protecting personnel and facilities in the building that requires the blocking of chemical agents or other confidentiality in the NBC situation, The purpose of the present invention is to provide an electric sliding crimped secret door which can be operated by a lock door, which is very convenient to operate, and can monitor and control the access of external personnel inside the facility.
