Description

Technical Field

[0001] The present application relates to the technical field of civil air defense doors, and in particular to a suspended plate hinge seat of a civil air defense door. Background Art

[0002] The hanging plate of the civil air defense door refers to the hanging door plate on the civil air defense door, which is usually used for the opening and closing of the civil air defense door in protective engineering. The hanging plate is generally made of steel plate, has a certain strength and protection ability, and can withstand external impact and pressure. When the civil air defense door is closed, the hanging plate will be hung above the door opening and connected to the door leaf through the opening and closing mechanism to play a sealing and protective role. When the civil air defense door needs to be opened, the hanging plate will be separated from the door leaf through the opening and closing mechanism so that the door leaf can be opened freely. The design and manufacture of the hanging plate need to comply with relevant standards and specifications to ensure that it has good protective performance and stability. However, the existing hanging plate hinge seat of the civil air defense door usually adopts an integrated design. When a component in the hinge seat is damaged, the entire hinge seat needs to be replaced, and the maintenance cost is high. Utility Model Content
