Electric civil air defense door capable of being locked by password

Abstract

The invention discloses an electric civil air defense door capable of being locked by a password. The electric civil air defense door comprises a door frame device and a door body device, wherein thedoor body device is installed at the middle position of the door frame device, a turning plate is driven by manually rotating of a front hand wheel to rotate to drive bevel gears to rotate, the bevelgears drive a conical gear to rotate to drive threaded rods to rotate, and then locking rods are driven to move, so that the civil air defense door is opened or locked; and when the electric civil airdefense door is used as a password civil air defense door, a fixed plate is driven by electric cylinders to move so as to drive the bevel gears to move, the bevel gears are disengaged from the conical gear, the civil air defense door cannot be opened or closed by rotating the front hand wheel, and the password lock is completed. When the bevel gears are engaged with the conical gear, the bevel gears are driven by a stepping motor to rotate so as to drive the conical gear to rotate, and the threaded rods are driven to rotate to enable the locking rods to move, so that the locking rods lock oropen the civil air defense door, the function of automatically locking or opening the civil air defense door by inputting the password is achieved, the operation is simpler and more convenient, and the safety performance is improved.

Description

technical field [0001] The invention relates to the technical field of civil air defense equipment, in particular to an electric civil air defense door that can be password-locked. Background technique [0002] The civil air defense door is the door of the entrance and exit of the people's protection project. The classification of the civil air defense door is relatively clear. , the role of disaster prevention and mitigation. Most of the traditional air defense doors are opened or locked by the handwheel, which is very time-consuming and laborious, and it is relatively easy to open, and the closing effect is poor. For example, the Chinese invention patent with the patent number 201610287309. The door leaf, seal, single-handle interlocking lock and hinge; the door leaf is a light-weight door leaf, and the door leaf and the door frame are hingedly connected by hinges; the single-handle interlocking lock set on the door leaf includes an outer handle, which is rotated horizont...

Problems solved by technology

Most of the traditional air defense doors are opened or locked by the handwheel, which is very time-consuming and laborious, and it is relatively easy to open, and the closing effect is poor. For example, the Chinese invention patent with the patent number 201610287309. The door leaf, seal, single-handle interlocking lock and hinge; the door leaf is a light-weight door leaf, and the door leaf and the door frame are hingedly connected by hinges; the single-handle interlocking lock set on the door leaf includes an outer handle, which is rotated horizontally through the first horizontal rotation mechanism. The shaft rotation is arranged on the outside of the door leaf; the single-handle linkage locking includes an outer handle and an inner handle arranged on the inside of the door leaf in a manner of rotating around a horizontal axis through the first horizontal rotation mechanism; multiple lock heads, along the circumference of the door leaf They are arranged on the inner side of the door leaf in turn, and each lock head rotates around the horizontal axis; multiple connecting rods are connected from head to tail to form a square with one side open, and the square connecting rods are arranged on the inner side of the door leaf as a whole. One of the connecting rods is rotatably connected with the inner handle, and multiple connecting rods are correspondingly rotatably connected with lock heads

[0003] By studying the above-mentioned existing civil air defense doors, it is found that its sealing effect is poor, and it is very time-consuming and labor-intensive to operate the whole process manually, and it is relatively easy to open, which has potential safety hazards and can only be used as ordinary civil air defense doors. Therefore, it is urgent to invent a safety High-performance password-lockable electric civil air defense door
