Description

Automatic opening safety door for fire and method

Technical Field

The invention relates to the field of fire fighting, in particular to an automatic opening safety door in a fire disaster and a method thereof.

Background

The current burglary-resisting door is mostly not installed built-in emergency exits, the gate is just the only passageway that can flee, at this moment if the gate is firmly stifled by the burglary-resisting door, fire fighter also is difficult to get into from the gate, so indoor personnel take place dangerous probability and will greatly increased, can not open in emergency, at present, intelligence house is more and more popularized, make family life more and more convenient, a lot of family burglary-resisting doors also all are intelligent security door locks, can pass through the fingerprint, the lock is opened to the password, the vexation of carrying the key has been removed from, however, along with the development of technique, people do not satisfy simple intelligence of this type, hope that the burglary-resisting door can bring better experience for the user. The existing anti-theft door has an excellent anti-theft effect, but under special conditions, the anti-theft door can also cause danger to users, for example, when a fire disaster occurs indoors, the users cannot open the anti-theft door to escape at the first time due to factors such as tension, and further danger is caused.

The patent application number CN109993870A discloses a burglary-resisting door system convenient for fire rescue, which comprises an intelligent door bell module, a display terminal, a wireless network and a sensor module, wherein the intelligent door lock module, an alarm module, the intelligent door bell module, the display module and the sensor module are all electrically connected with a power supply; the intelligent door lock module comprises a fingerprint input module, a password input module and an opening/closing lock module, the opening/closing lock module is internally provided with a fingerprint storage unit and a password storage unit, the fingerprint input module is used for inputting fingerprints of users, the password input module is used for inputting passwords of the users, and the opening/closing lock module is used for judging the correctness of an input result of the fingerprint input module or the password input module and opening/closing the anti-theft door lock. The patent does not relate to the automatic opening mechanism of installation between the door body and the door frame to drive opening and the closure of the whole door body, also do not disclose the slide and make a round trip to slide on the lead screw under the drive of motor, let the slip of slide all receive control, can not take place to break away from, do not disclose the connecting rod still more and rotate around first pivot and second pivot respectively, drive the door body and open or close, can not influence the rotatory angle scheduling problem of its door body.

Patent application number CN207363464U discloses an automatic fire locking structure for windows, which is located on the upper edges of a window frame and a window sash and comprises a four-bar hinge, a door closer and a transmission device; the four-connecting-rod hinge is connected with the window frame and the window sash; the door closer is arranged on the upper edge of the window frame; the transmission device is arranged on the upper edge of the window sash and is connected with the door closer through a transmission rod; the transmission device can provide resistance in a normal state to enable the window sash to keep different positions in an opening state, and can reduce the provided resistance in a fire state to enable the window sash to be closed under the action of the door closer. Therefore, the patent discloses a protection mode of a door and window, when a fire disaster occurs, a heated explosion tube 36 is heated to burst, so that an ejection body 35 is driven by a compressed spring 34 to eject along a rectangular stamping opening on a spring seat 32 to a position far away from one end provided with an ejection-resistance assembly, and strikes a transmission slide block positioned at the upward bent top end of a resistance spring piece 39, so that the transmission slide block slides to the end far away from the end provided with the ejection-resistance assembly through power provided by a transmission rod 46 from a door closer 2 to drive a window sash to close, thereby realizing the function of automatically closing in case of fire disaster, preventing smoke dust from entering a room and striving for time for escape of people, but the patent does not relate to a specific locking structure, does not disclose an automatic opening mechanism arranged between a door body and a door frame so as to drive the whole door body to open and close, nor discloses that a sliding plate slides back and forth on a lead screw under the, let the slip of slide all receive control, can not take place to break away from, the connecting rod that also does not disclose this application is rotatory around first pivot and second pivot respectively, drives the door body and opens or close, can not influence the rotatory angle of its door body.

Therefore, it is desirable to provide an automatically opening safety door, which can be automatically opened when a fire breaks out indoors, particularly, can be opened mechanically, so that people in a room can leave the door quickly, and the tragedy that people are locked in the room and are burned is prevented; however, it is also noted that if the automatic door is automatically opened upon occurrence of a fire, the automatic opening of the door upon occurrence of a fire in one room may cause the fire to continue to spread in an adjacent room extending along the opened door, and the fire may be more intense due to increased air flow after the door is opened, thereby causing a larger fire. Meanwhile, if a small fire occurs, the door is opened but the corresponding person does not appear, which may cause indoor things to be hijacked by people when the fire occurs.

In view of the above technical problems, no effective technical means for solving the above technical problems is available at present.
