Description
Technical Field
The utility model relates to a people's air defense equipment, in particular to explosion-proof people's air defense door.
Background
People's air defense is also called civil defense, which is an international common word and is an activity that governments mobilize and organize the masses, take measures of air attack prevention, disaster resistance and relief, implement rescue actions and prevent and reduce disaster harm. People's air defense door belongs to civil defense protective equipment. When the civil air defense door is impacted by explosion, the pressure born by the hinge and the lock tongue lock is larger, and the impact resistance effect of the traditional civil air defense door is not ideal; moreover, as the whole mass of the civil air defense door is large, the traditional locking mechanism is influenced by the structure, the civil air defense door can be operated by using large force, and the locking effect is not ideal; meanwhile, due to the low use frequency and the influence of low humid environment and dust, the lock bolt is easy to be blocked, and the normal use is influenced.
SUMMERY OF THE UTILITY MODEL
To above problem, the utility model provides an explosion-proof people's air defense door that simple structure is compact, shock-resistant effectual, and easy operation is convenient.
The technical scheme for solving the problems specifically comprises
An explosion-proof people's air defense door which characterized in that: the utility model discloses a civil air defense door body and locking device, wherein locking device includes hand wheel, screw rod and locking Assembly, and the head and the hand wheel connection of screw rod are installed in the cooperation on the screw rod simultaneously, and the free bearing is fixed at the nut lateral wall, and sector gear installs at the civil air defense door originally internally with rotating.
Further, this internal retaining collar that is fixed with of people's air defense door, the screw rod cover is established in the retaining collar, the lateral wall circumference equipartition of retaining collar have with the same bar groove of free bearing quantity, the length direction in bar groove is on a parallel with the axis direction of retaining collar.
Further, the screw rod is including connecting gradually and the first body of rod, the second body of rod and the third body of rod that the diameter becomes big in proper order, the tip of the first body of rod is equipped with the hand wheel installation department that the cross section is regular polygon, the screw has been seted up to the terminal surface of hand wheel installation department, the lateral wall of the second body of rod is equipped with the external screw thread, the second body of rod with be equipped with the tool withdrawal groove between the third body of rod.
Further, the civil air defense door body is round, rectangular or oval.
Compared with the traditional civil air defense door, the utility model has the advantages of simple and compact structure, high strength and good impact-proof effect; the operation is easy and convenient, and the locking effect is good; difficult card is died, can adapt to different operational environment, long service life.
