Anti-separation device for movable fan of translating automatic door

Abstract

The invention discloses an anti-separation device for a movable fan of a translating automatic door. The anti-separation device comprises movable fan limiting devices and movable fan supporting devices. The movable fan limiting devices include anti-separation rotating shaft devices and movable fan positioning locking devices. The lower ends of the anti-separation rotating shaft devices are arranged in top vertical frames of movable fans and the upper ends are fixedly connected with automatic door brackets arranged at a case. The upper ends of the movable fan positioning locking devices are arranged at the automatic door brackets and the lower ends are in locked connection with the movable fans. The upper ends of the movable fan supporting devices are fixed in vertical frames correspondingto the anti-separation rotating shaft devices at the bottoms of the movable fans and the lower ends of the movable fan supporting devices are arranged at a ground rail and move along the ground rail direction. Therefore, a problem that the door fan can not be opened or the door fan can not be pushed because the door fan is dragged on the ground at the moment of opening is solved. Moreover, when afire occurs or an emergency occurs, emergency evacuation of the personnel is realized and thus the personnel is rescued from the dangerous environment safely and thus the personal safety is ensured.

Description

technical field [0001] The invention relates to the technical field of translational automatic doors, in particular to a detachment prevention device for a movable leaf of a translational automatic door. Background technique [0002] The emergency evacuation automatic door is a kind of automatic sliding door, which adds the emergency evacuation function on the basis of the ordinary automatic sliding door, that is, the movable leaf and the fixed leaf can realize 90-degree horizontal opening in any state and any position. The basic composition of the ordinary automatic sliding door is two fixed leaves on both sides and two movable leaves in the middle. Therefore, the passage width is close to twice that of ordinary automatic sliding doors. When a fire or other accident occurs in a closed place, people will subconsciously run towards the entrance and exit. In the case of a power failure, ordinary automatic sliding doors cannot work, but emergency evacuation automatic doors can...
