Anti-theft doors are equipped with anti-theft locks, which can resist abnormal opening under certain conditions within a certain period of time. Doors with certain safety protection performance and meeting the corresponding anti-theft safety level are mainly reflected in the intelligence of their locks, including various types of electronic anti-theft locks that have begun to be widely used, such as fingerprints, passwords, IC card locks, etc. With the advancement of technology, in addition to replacing traditional mechanical locks with smart locks, IoT security doors will also be combined with smart home systems with functions such as security, home appliance control, and elderly and child care, and can realize network alarm, video surveillance, data transmission and remote control. These are all manifestations of intelligence. The door frames and door leaf components of existing anti-theft doors should have smooth and clean surfaces. Although they look more beautiful and smooth, they have a relatively simple structure and usually have the following problems;
[0003] 1. Most anti-theft doors are not sealed enough and cannot prevent smoke. Once a fire occurs downstairs, smoke will gather in the corridor and slowly penetrate into the room through the gap between the fan component and the door frame, causing indoor air pollution;
[0004] 2. If the fire spreads to the door frame and nearby areas of the security door, people inside the room can only close the security door and passively wait for rescue, and cannot take the initiative to extinguish the fire and cool down the room outside the door. Utility Model Content

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technical personnel in this field without creative work are within the scope of protection of the utility model.
[0021] See also Figures 1 to 3 The utility model provides a technical solution: a double fireproof and highly sealed anti-theft door, comprising a door frame assembly 1, the front of the door frame assembly 1 is connected to a door panel 2 through a hinge, a sealing assembly 3 is installed inside the door panel 2, a sealing strip 4 is bonded to the top of the door panel 2, and an operating hole 5 is provided on the back of the door panel 2.
[0022] The door frame assembly 1 includes an outer frame 101 , a smoke alarm 102 is installed on the front of the outer frame 101 , a water pipe 103 is plugged into the top of the outer frame 101 , a nozzle 104 is installed at one end of the water pipe 103 , a water tank 105 is plugged into the bottom of the water pipe 103 , and a groove 106 is provided on the inner wall of the outer frame 101 .
[0023] The sealing assembly 3 includes a sealing plate 301 which is slidably connected to the side of the door panel 2. A connecting rod 302 is welded to one side of the sealing plate 301. The other end of the connecting rod 302 is movably connected to a support rod 303. The other end of the support rod 303 is movably connected to a slider 304. The internal thread of the slider 304 is connected to a screw rod 305. The top of the screw rod 305 is equipped with the output shaft of a motor 306.
[0024] In this embodiment, Figure 1 As shown, the surface of the screw rod 305 is provided with two sets of positive and negative threads, and the screw rod 305 is rotated by the motor 306; it should be noted that the two sets of positive and negative surfaces of the screw rod 305 are respectively threadedly connected to the two sliders 304, which are operated through the operating hole 5 on the back of the door panel 2 to start the motor 306, and the motor 306 can drive the screw rod 305 to rotate forward and reverse.
[0025] In this embodiment, Figure 1As shown, the sealing plate 301, the connecting rod 302, the support rod 303 and the slider 304 are set as a group, and there are two groups of movements in total; it should be noted that when the motor 306 drives the screw rod 305 to rotate forward, the screw rod 305 is driven to rotate forward, the two sliders 304 move closer to the middle, the support rod 303 bends, and the connecting rods 302 at both ends are driven to squeeze toward the two ends, further squeezing the sealing plates 301 on both sides outward and sliding, and when the motor 306 reverses, it drives the sealing plates 301 to slide inward and be stored.
[0026] In this embodiment, Figure 1 As shown, the surface of the sealing plate 301 is provided with a polyurethane coating, and the sealing plate 301 is embedded in the groove 106 and moves; it should be noted that when the sealing plate 301 slides to both sides, one side of the sealing plate 301 will be embedded in the groove 106, tightly fitting with the inner wall of the groove 106, increasing the gap between the door panel 2 and the left and right sides of the outer frame 101, and a polyurethane coating is provided on the surface of the sealing plate 301 to increase the sealing and wear resistance.
[0027] In this embodiment, Figure 1 As shown, there are two sealing strips 4, and the other sealing strip 4 is located at the bottom of the door panel 2; it should be noted that the sealing strip 4 is composed of a number of triangular rubber strips, and sealing strips 4 are provided at the top and bottom of the door panel 2. When the door panel 2 is rotated and closed, the sealing strips 4 block the gaps at the upper and lower ends between the door panel 2 and the outer frame 101.
[0028] In this embodiment, Figure 1 As shown, a water inlet is provided on the surface of the water tank 105, and a small water pump is installed inside the water tank 105; it should be noted that when the distance outside the door panel 2 is close to the fire point, water can be added to the water inlet indoors to start the small water pump in the water tank 105. The small water pump pumps water into the water pipe 103, and the water is sprayed through the nozzle 104 at the other end of the water pipe 103. The nozzle 104 sprays in all directions directly below the door panel 2 to delay the spread of the fire.
[0029] The use method and advantages of the utility model: When the double fireproof and highly sealed anti-theft door is used, the working process is as follows:
[0030] like Figure 1 , Figure 2 and Figure 3As shown, first rotate and close the door panel 2, and the door panel 2 overlaps with the door frame assembly 1. When the door panel 2 is rotated and closed, the gaps at the upper and lower ends between the door panel 2 and the outer frame 101 are blocked by the sealing strip 4. Once a fire occurs outside the door panel 2, the smoke alarm 102 sounds an alarm. The operation is operated through the operation hole 5 on the back of the door panel 2 to start the motor 306. The motor 306 can drive the screw rod 305 to rotate forward and reverse. When the screw rod 305 rotates forward, the two sliders 304 move closer to the middle, and the support rod 303 bends, driving the connecting rods 302 at both ends to squeeze toward the two ends, further squeezing the sealing plates 301 on both sides outward. When the fire starts, one side of the sealing plate 301 will be embedded in the groove 106 and fit tightly with the inner wall of the groove 106, thereby increasing the gap between the door panel 2 and the left and right sides of the outer frame 101, and achieving better sealing to prevent smoke from entering the room through the gap. If the door panel 2 is close to the fire point, water can be added to the water inlet in the room to start the small water pump in the water tank 105. The small water pump will pump water into the water pipe 103, and the water will be sprayed through the nozzle 104 at the other end of the water pipe 103. The nozzle 104 will spray in all directions directly under the door panel 2, thereby reducing the temperature near the door panel 2, delaying the spread of fire, and achieving double fire prevention effects of fire prevention and smoke release.
[0031] The above shows and describes the basic principle, main features and advantages of the utility model. Technical staff in this industry should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model will have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
