Problems solved by technology

The existing evacuation door is manually pulled down by the wrench, and the other end of the wrench moves up, so that the button rod moves up, thereby driving the connecting rod to rotate clockwise, thereby driving the pull rod head to move to the left, and the pull rod head is pulled to the left by the pull rod At the same time, it drives the gear shaft and the lock tongue to move to the left, so that the lock tongue is released from the lock hole, unfixed, and the door is opened. This manual structure cannot be opened quickly in case of a major accident, and requires a certain reaction time. Time will cause serious consequences, and safety cannot be guaranteed, so now a fire exit door quick opening mechanism is needed

Description

Technical field [0001] The invention is a quick opening mechanism for a fire passage door, belonging to the field of fire protection. Background technique [0002] Currently, fire exit doors are quickly opened doors located at the emergency evacuation exits of buildings. Fire doors are installed in the escape passages of large underground squares. The doors are usually closed, strong and well-sealed. Once there is a danger underground, people can open the safety door from the inside to escape. The existing evacuation door manually pulls the wrench downwards, and the other end of the wrench moves upwards to move the button rod upwards, thereby driving the connecting rod to rotate clockwise, thereby driving the rod head to move to the left, and the rod head is pulled to the left through the rod The joint drives the gear shaft and the lock tongue to move to the left at the same time, so that the lock tongue is separated from the lock hole, unfixed, and opened the door. This manual ...
