Safety door capable of automatically opening during fire and method

Abstract

The invention discloses a safety door capable of automatically opening during fire and a method. The safety door comprises a door frame mounted on a wall and a door body movably connected with the door frame through a hinge, wherein an intelligent lock locked together with the door frame is mounted on the edge of the middle of the door body, an automatic opening mechanism is installed between thedoor body and the door frame, and an induction mechanism is mounted on the indoor surface of the door body. The automatic opening mechanism comprises a door head seat, a sliding seat, a motor, a leadscrew and a sliding plate, wherein the door head seat is fixed on the top surface, close to the door frame, of the door body through a screw. The safety door and the method have the beneficial effectsthat after any one of temperature, sound and smoke data exceeds a set threshold value, a processor controls the intelligent lock to open the door firstly, the processor controls a motor, the lead screw rotates to drive the sliding plate to horizontally slide leftwards on the sliding seat, in the process that the sliding plate horizontally slides leftwards on the sliding seat, a lantern ring of aconnecting rod rotates around a second rotating shaft, the connecting rod is pushed to rotate around a first rotating shaft, the door body is driven to be opened, the purpose of automatic door openingis completed, and the escape time is prolonged.

Description

technical field [0001] The invention relates to the field of fire protection, in particular to a fire automatic opening safety door and a method thereof. Background technique [0002] Most of the existing anti-theft doors are not equipped with built-in escape doors. The door is the only escape channel. If the door is firmly blocked by the anti-theft door and it is difficult for firefighters to enter through the door, the probability of danger for indoor personnel will be greatly increased. increase, and cannot be opened in an emergency. At present, smart homes are becoming more and more popular, making family life more and more convenient. Many home anti-theft doors are also intelligent anti-theft door locks, which can be opened by fingerprints and passwords. However, with the development of technology, people are not satisfied with this kind of simple intelligence, and hope that the anti-theft door can bring a better experience to users. The anti-theft effect of the existi...

It can be seen that this patent discloses the protection mode of doors and windows. When a fire breaks out, the heated detonator 36 is heated and bursts, so the projectile 35 is driven by the compressed spring 34 along the rectangular punching opening on the spring seat 32 to move away from the ejection device. - One end of the resistance assembly is ejected and hits the transmission slider at the top of the upward bending of the resistance spring sheet 39, so that the transmission slider is driven away from the end of the ejection-resistance assembly by the power from the door closer 2 provided by the transmission rod 46 Sliding, drives the window sash to close, realizes the function of automatic closing in case of fire, prevents fire smoke and dust from entering the room, and buys time for personnel to escape. However, the patent does not involve how to set up a locking structure, nor does it disclose the installation between the door body and the door frame. The automatic opening mechanism drives the opening and closing of the entire door body, and there is no disclosure that the slide plate slides back and forth on the lead screw under the drive of the motor, so that the sliding of the slide plate is controlled and will not break away, nor does it disclose the connection of the present application. The rods rotate around the first and second shafts respectively to drive the door to open or close without affecting the rotation angle of the door

[0005] Therefore, it is desirable to provide a safety door that can be opened automatically when a fire breaks out in the room, especially by mechanical opening, so that the people in the room can leave quickly and prevent the tragedy of people being locked in the room and being burned to death; It should also be noted that if the automatic door opens automatically when a fire breaks out, then in the event of a fire, maybe when a fire breaks out in one room, the door automatically opens, which may cause the fire to continue to extend along the adjacent room where the door is open. , then it will inevitably cause the fire to continue to spread. Moreover, after the door is opened, the fire may become more intense due to the increased air flow, thus causing a larger fire.

At the same time, if a small fire occurs, the door is opened but the corresponding person does not appear, which may lead to people taking advantage of the fire to rob

[0006] For the above-mentioned technical problems, there is currently no effective technical means to solve the above-mentioned technical problems
