Embodiment Construction

[0025] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0026] A kind of civil air defense engineering protective equipment, such as figure 1 and figure 2 , including a door frame installed in the wall to match the wall hole and a door leaf 1 rotatably connected to one side of the door frame. When the door leaf 1 rotates around the hinge axis with the door frame, a connecting ring 11 is provided on the side of the door leaf 1 close to the ground. There are arc-shaped grooves 12 distributed along the connecting ring 11 as the door leaf 1 rotates on the ground, and a driving member for driving the connecting ring 11 to move along the arc-shaped groove 12 is provided in the arc-shaped groove 12 .

[0027] like figure 1 and figure 2 , the driver will drive the connecting ring 11 to move in the arc-shaped groove 12, and the arc-shaped groove 12 is opened along with the rotation path of the door leaf 1. At this tim...

Abstract

The invention discloses protective equipment for civil air defense engineering, achieves the advantage that a door leaf can be automatically opened when needing to be opened, and relates to the technical field of civil air defense engineering. The protective equipment is technically characterized in that when the door leaf rotates around a door frame hinge shaft, a connecting ring is arranged at the end, close to the ground, of the side face of the door leaf, an arc-shaped groove distributed along the connecting ring along with rotation of the door leaf is formed in the ground, and a driving piece for driving the connecting ring to move along the arc-shaped groove is arranged in the arc-shaped groove.

Description

technical field [0001] The invention relates to the technical field of civil air defense engineering, more specifically, it relates to a protective equipment for civil air defense engineering. Background technique [0002] Civil air defense projects are underground protective buildings built separately to protect personnel and material shelters, civil air defense command, and medical rescue in wartime, and basements that can be used for air defense in wartime built in conjunction with ground buildings. Civil air defense doors are the doors of civil air defense engineering entrances. The door is the door of the entrance and exit of the civil protection project. The classification of civil air defense doors is relatively clear. A partition door is a door used to separate two spaces. [0003] Notification number is that the Chinese patent of CN211975062U discloses a kind of protective airtight partition door of underground railway civil air defense engineering, comprises the d...
