Door leaf supporting device for civil defense door
The invention discloses a door leaf supporting device for a civil defense door. The door leaf supporting device comprises a door frame fixed to a wall; hinges are installed between the inner walls ofthe two sides of the door frame; door plates are installed on the hinges; buckles are welded to the ends, close to each other, of the door plates; universal wheels are welded to the bottoms of the door plates; guide rails are rotatably connected with the bottoms of the universal wheels; sliding grooves are formed in the tops of the door plates correspondingly; sliding blocks are slidably connectedwith the interior of the sliding grooves correspondingly; a telescopic mechanism is rotatably connected between the two sliding blocks in a butt clamping mode; the telescopic mechanism comprises a sleeve and a sliding rod which are rotatably connected with the two sliding blocks correspondingly; and a fixing bolt is in threaded connection with the outer wall of the end, close to the sliding rod,of the sleeve in a penetrating mode. According to the door leaf supporting device for the civil defense door, the guide rails are arranged on the ground, the universal wheels are connected with the tops of the guide rails, and the universal wheels are welded to the bottoms of the door plates, so that the door plates do not need to be provided with supporting force through the hinges in the openingand closing process, the supporting force only needs to be provided through the universal wheels, and losses of the hinges in the using process are reduced.
本发明公开了一种人防门用门扇支撑装置，包括与墙体固定的门框，所述门框两侧内壁之间均安装有铰链，且铰链上均安装有门板，所述门板相互靠近的一端均焊接有卡扣，且门板底部均焊接有万向轮，所述万向轮底部均转动连接有导轨，所述门板顶部均开有滑槽，且滑槽内均滑动连接有滑块，两个所述滑块之间均对夹转动连接有伸缩机构，伸缩机构包括分别与两个滑块转动连接的套筒和滑杆，且套筒靠近滑杆的一端外壁贯穿螺接有固定螺栓。本发明通过在地面上设置有导轨，导轨的顶部连接有万向轮，万向轮与门板的底部进行焊接，门板在打开与关闭过程中不需要铰链来提供支持力，只需要通过万向轮来提供支持力，减少了铰链在使用过程中的损耗。
