[0002] Fire doors are specifically designed to prevent the spread of fire and smoke during a fire, maintaining their structural stability, integrity, and thermal insulation for a certain period of time. Fire doors are typically installed in fire compartments, evacuation stairwells, vertical shafts, and other locations within a building. Their primary function is to provide escape opportunities in the event of a fire, isolate the source of the fire as much as possible, and slow the spread of the fire.

[0003] Chinese patent publication number CN212478987U discloses a highly sealed fire door. This fire door's sealing performance is enhanced by installing a fitting strip inside a groove. A sealing layer is provided on the side of the fitting strip, and expanded graphite is provided inside the sealing layer. The expanded graphite expands when heated, further enhancing the fire door's sealing performance in a fire scene.

[0004] In the above patent, the fire door may be damaged by external forces such as impact or explosion impact in a fire scene. There is a problem that the structure of the fire door is easily damaged after being hit, which in turn causes the fire to spread. Therefore, it does not meet the existing needs, and a highly sealed and anti-collision double-leaf fire door is proposed. Utility Model Content

[0005] The purpose of the present utility model is to provide a highly sealed and anti-collision double-leaf fire door, by arranging baffles at the upper and lower sides of the door body, installing a movable anti-collision plate on one side of the door body, and providing an installation room above the door frame. A motor and a connecting piece are arranged inside the installation room, and the connecting piece is connected to the anti-collision plate. When a fire occurs, the motor drives the connecting plate to move, and then drives the anti-collision plate to move to the inside of the baffle. The door frame and the door body form a stable whole, so that the fire door has the ability to prevent collision, which can solve the problems in the prior art.

[0006] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a highly sealed and anti-collision double-leaf fire door, comprising a door body and an installation chamber, wherein the installation chamber is located above the door body, a door frame is provided on the outside of the door body, a solid expansion strip is provided between the door body and the door frame, the solid expansion strip is connected to the door body, a boss is provided on the side of the door body, a sealing strip is provided on the side of the boss, an anti-collision plate is provided below the installation chamber, a screw is provided inside the installation chamber, a bearing seat is provided at one end of the screw, the bearing seat is sleeved on the screw, and a motor is provided at the other end of the screw, and the motor and the bearing seat are both fixed on the inner wall of the installation chamber.

[0007] Preferably, a handle and a baffle are provided on the side of the door body, the baffle is L-shaped, and one end of the baffle is connected to the door body.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] To solve the problem that the fire door is easily damaged after being hit in the fire, which may cause the fire to spread, please refer to Figure 1-4 The utility model provides an embodiment: a highly sealed and anti-collision double-leaf fire door, comprising a door body 1 and an installation chamber 3, the installation chamber 3 being located above the door body 1, a door frame 2 being provided on the outside of the door body 1, a solid expansion strip 201 being provided between the door body 1 and the door frame 2, the solid expansion strip 201 being connected to the door body 1, a boss 103 being provided on the side of the door body 1, a sealing strip 104 being provided on the side of the boss 103, an anti-collision plate 4 being provided below the installation chamber 3, a screw 302 being provided inside the installation chamber 3, a bearing seat 303 being provided at one end of the screw 302, the bearing seat 303 being sleeved on the screw 302, a motor 301 being provided at the other end of the screw 302, and the motor 301 and the bearing seat 303 being fixed on the side wall inside the installation chamber 3.

[0022] A handle 101 and a baffle 102 are provided on the side of the door body 1. The baffle 102 is L-shaped. One end of the baffle 102 is connected to the door body 1. There is a gap between the baffle 102 and the door body 1 that can accommodate the anti-collision plate 4. A groove 105 is provided on the contact surface between the door body 1 and the door frame 2. The solid expansion strip 201 is located inside the groove 105. The material of the solid expansion strip 201 is heat-sensitive plastic.

[0023] When the two door bodies 1 of the double-leaf fire door are closed, the sides of the two bosses 103 are in contact, and the sealing strip 104 blocks the gap between the door bodies 1, thereby improving the sealing ability of the fire door; when the fire spreads to the front of the double-leaf fire door and the fire door is in a closed state, the door body 1 is in contact with the door frame 2, and the solid expansion strip 201 expands due to heat to block the gap between the door body 1 and the door frame 2, thereby improving the sealing ability of the fire door, which can effectively prevent the circulation of smoke and further reduce the risk of suffocation and poisoning caused by inhalation of toxic smoke.

[0024] A through slot 309 is provided below the installation chamber 3, and a track 308 is provided on one side of the through slot 309. The track 308 is connected to the installation chamber 3 and is located inside the installation chamber 3. A support 305 is provided in the middle of the screw 302, and a connecting member 306 is provided on the side of the support 305. A pulley 307 is provided inside the connecting member 306, and the pulley 307 is connected to the axis of the connecting member 306. A mounting plate 304 is provided below the connecting member 306, and the mounting plate 304 is located inside the through slot 309. The upper end of the mounting plate 304 is connected to the connecting member 306, and the lower end of the mounting plate 304 is connected to the anti-collision plate 4.

[0025] When a fire occurs, the starting motor 301 drives the screw 302 to rotate, and then the connecting piece 306 moves along the track 308, thereby driving the anti-collision plate 4 to move to the gap between the baffle 102 and the door body 1. At this time, the door frame 2, the door body 1 and the anti-collision plate 4 form a stable whole, so that the fire door has the ability to resist impact, enhances the internal structure stability of the double-leaf fire door, prevents the problem of fire spreading due to the damage of the fire door, and further improves the reliability of fire prevention of the fire door in a fire scene.

[0026] Working principle: When a fire breaks out, close the double-leaf fire door. At this time, the door body 1 is in contact with the door frame 2. The gap between the door body 1 and the door body 1 is blocked by the sealing strip 104, and the gap between the door body 1 and the door frame 2 is blocked by the solid expansion strip 201 due to heat expansion, which can effectively prevent the circulation of smoke in the fire scene; at the same time, the anti-collision plate 4 moves to the gap between the baffle 102 and the door body 1, and the door frame 2, the door body 1 and the anti-collision plate 4 form a stable whole, so that the fire door has the ability to withstand external impacts, thereby stabilizing the internal structure of the fire door and preventing the spread of fire due to the destruction of the fire door.
