Description

Technical Field

[0001] The present invention relates to the technical field of fire doors, in particular to an intelligent linkage type automatic locking structure for indoor building fire doors. Background Art

[0002] Garage fire doors have fire resistance, stability, integrity and thermal insulation, and can effectively contain the spread of fire and high-temperature smoke to other areas when a fire occurs. Fire doors provide a critical time window for personnel evacuation by delaying the spread of smoke, reducing the temperature in the surrounding area, and preventing high temperatures from igniting other combustibles. Currently, double-leaf fire doors are widely used. The current automatic locking fire doors are not easy to prevent obstruction. When there are obstructions such as garbage, it will directly affect the closing of the fire door and increase the spread of fire. At the same time, the heat wave pressure or flames when traditional fire doors are opened and closed can easily cause harm to personnel, making it inconvenient to prompt personnel to evacuate safely. At the same time, it is not easy to ensure the sealing of the wall during installation of traditional fire doors.

[0039] Among them, the rotary door closing member 4 includes: a balanced rotary door 401 and a torsion spring 4011. The balanced rotary door 401 is provided with a rotating shaft in the middle; the balanced rotary door 401 is rotatably mounted on the movable door 201 through the rotating shaft in the middle; the two sides of the balanced rotary door 401 are respectively attached to the inner side of the movable door 201; the limiting strip 2011 is used to limit the movable door 201; the bottom of the rotating shaft in the middle of the balanced rotary door 401 is sleeved with a torsion spring 4011, and the torsion spring 4011 is connected between the bottom of the rotating shaft on the balanced rotary door 401 and the movable door 201; the rotary door closing member 4 also includes: a rotary motor 402, a fixed part on the movable door 201 A rotary motor 402 is fixedly installed, and the output shaft of the rotary motor 402 is fixedly installed on the balanced revolving door 401; the delay control component 5 includes: a delay switch 501 and a switch baffle 502, and the delay switches 501 are fixedly installed on both sides of the track frame 101; the two movable doors 201 are fixedly installed with switch baffles 502; the two switch baffles 502 are respectively located above the two delay switches 501; the two delay switches 501 are respectively electrically connected to the two rotary motors 402, and the delay control component 5 can cooperate with the rotary door closing component 4 to assist in delay control of the rotary door closing component 4 to stop rotation. , ensuring that people have time to pass through in time. At the same time, the rotary door closing member 4 used is a central rotating shaft structure, which can be more suitable for fire prevention work. The balanced revolving door 401 is more balanced, especially for areas with different pressures on both sides, which can improve the stability of the balanced revolving door 401 and ensure that it can be reset by the elastic force of the torsion spring 401. At the same time, the delay control member 5 can be placed on one side of the balanced revolving door 401 to ensure that when people escape, they need to step on the delay switch 501 to control the door opening. When opening the door, stay away from the balanced revolving door 401 to prevent the high temperature and air pressure at the moment the balanced revolving door 401 is opened. Until the flames are ejected and further harm is caused to personnel, it can assist personnel in judging whether there are conditions for escape, avoiding the situation where traditional fire doors can only be opened by pushing them manually. The structural control is simple and reasonable. At the same time, this structure does not require manual pushing of the door, which can avoid burns caused by personnel directly pushing the balanced revolving door 401 after it is baked by high temperature. Personnel can stand and step on the delay switch 501. At this time, the delay switch 501 can control the rotary motor 402 to drive the balanced revolving door 401 to rotate. When there is no dangerous situation such as flame, personnel can quickly pass through the gap formed between the balanced revolving door 401 and the movable door 201 after it rotates.

[0040] Example 2, based on Example 1, the flatness detection member 6 includes: a fitting rubber pad 601 and a spring piece 602, the fitting rubber pad 601 is slidably sleeved in a circle of grooves provided on the back of the track frame 101; the fitting rubber pad 601 is a rectangular structure; a circle of spring pieces 602 are fixedly installed in a circle of grooves on the back of the track frame 101, and the circle of spring pieces 602 are elastic steel sheet structures; the inner side of the fitting rubber pad 601 is attached to the spring piece 602; the fitting rubber pad 601 is used to fit the wall; the fitting rubber pad 601 is a soft structure; the flatness detection member 6 also includes: a power connection fixing piece 603, a circle of spring pieces 602 are fixedly installed in a circle of grooves on the back of the track frame 101 The power fixing piece 603 is connected, and the ends of a circle of elastic pieces 602 are respectively aligned with a circle of power fixing pieces 603; the dislocation safety piece 7 includes: an electromagnet 701, a dislocation slider 702 and a tension spring 703. Two electromagnets 701 are fixedly installed on the track frame 101, and the two electromagnets 701, the elastic pieces 602 and the power fixing piece 603 are connected in series with the power supply; two dislocation sliders 702 are slidably installed on the track frame 101, and the two electromagnets 701 magnetically attract the dislocation sliders 702 respectively; a row of slots is provided on the dislocation slider 702; a tension spring 703 is fixedly installed on the bottom of the dislocation slider 702, and the other end of the tension spring 703 is connected to the inner side of the track frame 101; the two electric When the magnet 701 magnetically attracts the two misaligned sliders 702 respectively, a row of slots on the two misaligned sliders 702 are aligned with a row of through holes on both sides of the track frame 101; the row of through holes on both sides of the aligned track frame 101 are respectively used to pass bolts through for installation on the wall. The flatness detection member 6 is used in conjunction with the misalignment insurance member 7 to ensure that the wall surface is flat during the initial installation of the structure, that is, to ensure that the wall surface can better fit the back of the track frame 101, to ensure the sealing of the structure after installation, to reduce the risk of smoke leakage in the event of a subsequent fire, and to carry out comprehensive testing. At the same time, the structure can be installed with insurance, and can only be installed normally after ensuring that the wall surface and the track frame 101 are in fit. The bolts are anchored, otherwise the bolts cannot be installed normally, further standardizing the construction quality of the staff, ensuring the fireproof effect of the structure, and making the structure more reasonable. When the wall surface is uneven, even if glass glue is used to bond the track frame 101 to the wall surface, it will directly melt at high temperature, lose the seal, and aggravate the toxic gas pollution. The leveled wall surface can be completely fitted with a circle of spring pieces 602 and fitted with the electrical fixing piece 603. At this time, the series circuit is turned on, and the electromagnet 701 can magnetically attract the dislocation slider 702 upward and stretch the tension spring 703. At this time, a row of slots on the dislocation slider 702 is aligned with a row of through holes on both sides of the track frame 101, and the bolts can be smoothly inserted.

[0041] The working principle of this embodiment is as follows: First, after the smoke switch 102 detects a fire hazard, the switch of the smoke switch 102 can control the electric push rod 203 to extend, pushing the two movable doors 201 to close. At this time, as the movable door 201 moves, the squeezing protrusion 204 can be driven to squeeze the linkage switch 103. At this time, the driving roller 301 can be driven by the driving motor 302 to rotate in opposite directions. Once there is an obstacle between the two driving rollers 301, it can be pushed to one side by rolling friction. At this time, the two driving rollers 301 will fit together and close. As the two movable doors 201 move, the squeezing protrusion 204 can be driven to squeeze the linkage switch 103. 01 moves and closes, which can drive the positioning column 205 to move to the locking hole 1011. At this time, under the pressure of the spring at the tail of the positioning column 205, the positioning column 205 can be pushed into the locking hole 1011 for safety locking. When there are still people who need to evacuate after the moving door 201 is closed, the switch blocking piece 502 is driven by the moving door 201 to move and no longer blocks the delay switch 501. People can stand and step on the delay switch 501. At this time, the delay switch 501 can control the rotary motor 402 to drive the balanced revolving door 401 to rotate. When there is no flame, etc. In dangerous situations, people can quickly pass through the gap formed between the balanced revolving door 401 and the movable door 201 after the rotation. When the delay switch 501 is delayed, the torsion spring 4011 can elastically drive the balanced revolving door 401 to rotate and reset, closing the movable door 201. When the track frame 101 is attached to the wall, if the wall and the track frame 101 are not flat, with depressions or protrusions, the spring pieces 602 of a circle cannot completely squeeze the rubber pad 601 to elastically adhere to the wall. At this time, the local spring pieces 602 cannot contact the power fixing piece 603. At this time, the series The series circuit cannot be conducted. At this time, the row of slots on the offset slider 702 and the row of through holes on both sides of the track frame 101 are misaligned, and the bolts cannot be inserted. The staff needs to level the wall. After the leveling, the wall can completely fit and squeeze a circle of spring pieces 602, and fit the electrical fixing piece 603. At this time, the series circuit is conducted, and the electromagnet 701 can magnetically attract the offset slider 702 upward and stretch the tension spring 703. At this time, the row of slots on the offset slider 702 is aligned with the row of through holes on both sides of the track frame 101. At this time, the bolts can be smoothly inserted to install the track frame 101 on the wall.
