Description

Reclining device for civil air defense door Technical Field The utility model belongs to the technical field of civil air defense doors, and particularly relates to an inclined leaning device for a civil air defense door. Background In the ascending or descending process of the sealing beam structure of the civil air defense door, the sealing beam structure and the door leaf cannot be fixed firmly, so that the sealing beam structure and the door leaf are fixed through a plurality of fixing components, the movable relation between the sealing beam structure and the door leaf is ensured while the sealing beam structure and the door leaf are fixed, the existing fixing components can only be fixed with the door leaf, and the use requirement that the sealing beam structure can not be interfered to move up and down while the sealing beam structure is fixed cannot be met at the same time, so that the inclined leaning device for the civil air defense door is designed to solve the problems. Disclosure of Invention The utility model aims to provide a reclining device for a civil air defense door, which solves the problem that the existing fixing assembly can only be fixed with a door leaf, but cannot simultaneously meet the use requirement of being capable of not interfering with the up-and-down movement of a sealing beam structure while being fixed. In order to solve the technical problems, the utility model provides a reclining device for a civil air defense door, which is provided with a plurality of reclining devices which are respectively arranged at the back of each door leaf at intervals, Each reclining device comprises a reclining seat and side sliding plates arranged on two sides of the reclining seat in a sliding manner, one end of the reclining seat is fixedly arranged on the corresponding back of the door leaf, the other end of the reclining seat is provided with a limiting seat, the limiting seat is in matched limiting with the side sliding plates on two sides, the bottoms of the two side sliding plates are connected with sealing beam structures through connecting assemblies, the sealing beam structures are driven to move up and down through lifting mechanisms, so that the two side sliding plates of each reclining device are driven to slide up and down on the corresponding outer sides of the reclining seat, and the sealing beam structures are driven to be separated from or sealed with a lower frame of a door frame of a civil air defense door. Further, a first limiting inclined plane is arranged on the outer side of the upper portion of the side sliding plate of each reclining device, a second limiting inclined plane is arranged on the inner side of the limiting seat, and the first limiting inclined plane and the second limiting inclined plane are matched and limited. Further, the reclining seat is connected with the back of the door leaf through a fastening bolt.
