Description

Technical Field

[0001] The utility model relates to the technical field of civil air defense doors, in particular to a steel structure hanging rail type folding and sliding civil air defense door. Background Art

[0002] Civil defense, also known as civil defense, is an activity in which the government mobilizes and organizes the masses to take anti-air raid, disaster relief measures, implement rescue operations, and prevent and reduce disaster hazards. Among them, civil defense doors belong to civil defense protection equipment and are the doors at the entrances and exits of civil defense projects. Nowadays, most civil defense doors are open sideways, but the current civil defense doors are basically in an unused open state. After opening sideways, the civil defense doors will occupy a large area. In order to reduce the area occupied by the opening of the civil defense doors when not in use, a push-pull and translational opening and closing method will be adopted. However, the current push-pull and translational civil defense doors occupy a large horizontal area, and it is necessary to reserve a wide enough wall space on both sides of the door to open it.

[0003] The existing publication number is CN 215408265 U, which specifically discloses a translationally sliding opening and closing civil defense door, which includes a bottom track, a left door and a right door are slidably connected to the upper surface of the bottom track, a hole is opened on the right end surface of the left door, and a sliding block is slidably connected to the right end surface of the left door, a lock hole is opened at the end of the sliding block away from the left door, and a sliding handle is fixedly connected to the surface of the end of the sliding block away from the lock hole, a sliding groove is opened in the middle of the front surface of the left door, a lock groove is opened on the left end surface of the right door, a knob is rotatably connected to the front surface of the left end of the right door, a lock column is slidably connected to the front inner surface of the lock groove, an emergency switch is provided in the middle of the rear surface of the right door, and support plates are fixedly connected to the left and right ends of the bottom track, and the end of the support plate away from the bottom track is fixedly connected to the top track.

[0004] The existing public civil air defense doors are left-right rotating double-opening type or left-right track push-pull type. The rotating double-opening civil air defense door occupies a larger axial area when opened and closed, and the left-right track push-pull type occupies a larger horizontal wall area when opened.
