Problems solved by technology
However, when the power is off, the automatic control system of the equipment fails, and it can only be controlled manually, so the fast opening and closing of the locking mechanism cannot be realized.
In addition, since the handwheel device is still retained, there is still a risk of damage to the locking mechanism under wartime conditions, and the re-opening of the door leaf cannot be guaranteed.

Abstract
The invention relates to a civil air defense door locking device, a mounting method, a civil air defense door adopting the locking device and a start-stop method. The civil air defense door locking device allows a screwdriver set head to be inserted for operation comprises a worm gear reducer, a hand wheel, a sleeve, the screwdriver set head, a retaining cover and a bearing. The worm gear reducercomprises a reducer cabinet, a worm and a gear. The worm horizontally penetrates through the reducer cabinet, and the two ends of the worm penetrate out of the reducer cabinet. A square groove is formed in the first end of the worm, and the second end of the worm is provided with an integrated section. The hand wheel is rotationally connected with the second end of the worm. The sleeve sleeves a worm section, close to the first end of the worm, of the worm. The screwdriver set head is in pluggable connection with the square groove. The retaining cover covers the first end of the worm in a buckling mode and is fixedly connected with a limit baffle of the sleeve. The bearing is accommodated in a groove and is fixed to the worm through a lock washer and a grooved round nut. The civil air defense door locking device has the advantages of being simple in structure, fast to start and stop, and capable of improving the strength and reliability of the civil air defense door, and can be widelyapplied to civil air defense projects.
Description
technical field [0001] The invention relates to a locking device used on a civil air defense door and a civil air defense door equipped with the device, in particular to a flexible and convenient operation, a safe and stable civil air defense door locking device under the action of a shock wave load and a civil defense door equipped with the device, belonging to The technical field of civil air defense engineering. Background technique [0002] With the rapid development of science and technology, the corresponding technical indicators in the civil air defense engineering design specifications are also gradually improved, and higher requirements are put forward for the various performances of protective equipment. Civil air defense door lock refers to the mechanism used to fix the door leaf on the door frame after the door leaf is closed in place. Whether the working performance of the locking mechanism is reliable, whether the opening and closing is fast and smooth directl...
