[0019] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0020] The specific implementation of the present invention is described in detail below with reference to specific embodiments.

[0021] like Figures 1 to 5 As shown, an extremely narrow-edge escape and evacuation automatic door provided by an embodiment of the utility model includes a fixed door 1, an opening and closing component 2 and a movable component 3; the opening and closing component 2 includes an opening and closing motor 21, the end face of the opening and closing motor 21 is connected to a screw structure 22, the outer wall surface of the screw structure 22 is movably connected to a screw nut block 23, the outer wall surface of the screw nut block 23 is fixedly connected to the opening and closing door 24, the movable component 3 includes a storage chamber 31 opened inside the opening and closing door 24, the opening and closing door 24 is fixedly connected to a limiting electromagnet 32, a drying structure 36 and a heating wire 37 through the storage chamber 31, the end face of the limiting electromagnet 32 ​​is movably connected to a limiting iron column 33, the end face of the limiting iron column 33 is fixedly connected to the movable door 34, and the inner wall surface of the fixed door 1 is fixedly connected to a triangular scraper 4.

[0022] The extremely narrow-edge escape automatic door provided by the present invention can dry the surface of the evacuation door by means of the drying structure 36 and the heating wire 37, thereby preventing the evacuation door from icing on the surface in a low-temperature environment and increasing the safety of the evacuation door. By means of the triangular scraper 4, debris adhering to the surface of the movable door 34 can be scraped off when the movable door 34 is opened and closed horizontally, thereby avoiding clogging of the fixed door 1. By means of the limiting electromagnet 32 ​​and the limiting iron column 33, the limiting electromagnet 32 ​​can be powered off to release the restriction on the movable door 34, thereby facilitating the movable door 34 to be rotated ninety degrees for opening and closing, thereby increasing the adaptability of the evacuation door during escape and evacuation and avoiding the situation where the evacuation door cannot be opened due to power failure.

[0023] In the embodiment of the present invention, when in use, the opening and closing motor 21 is energized to drive the screw structure 22, so that the screw nut block 23 converts the rotational motion of the screw structure 22 into a linear motion, thereby moving the opening and closing door 24, driving the movable door 34 to open and close in the horizontal direction, so that the evacuation door is in an automatic opening and closing state. In low temperature and cold weather, the heating wire 37 is energized to emit heat, and the drying structure 36 is energized to start, and the air enters through the air inlet filter hole 302, and then the heat emitted by the heating wire 37 is blown to the air outlet hole 301. The surface of the movable door 34 is heated to prevent ice from forming on the surface of the movable door 34, thereby reducing the impact on the opening and closing of the evacuation door. When the movable door 34 is opened and closed in the horizontal direction, it will be affected by the triangular scraper 4 to scrape off the debris stuck on the surface of the movable door 34. In the event of an emergency, the limit electromagnet 32 ​​is powered off and loses its magnetic force, thereby releasing the magnetic adsorption with the limit iron column 33, and the movable door 34 can be pushed to rotate 90 degrees to open and close, thereby preventing the evacuation door from being unusable due to power outages in emergency situations, thereby increasing the efficiency of personnel escape and evacuation.

[0024] like Figure 3 and Figure 4 As shown, as a preferred embodiment of the present invention, the inner wall surface of the fixed door 1 is provided with a fixed slide groove 11, the outer wall surface of the opening and closing door 24 is fixedly connected with a fixed slider 25, and the outer wall surface of the fixed slider 25 is slidably connected to the fixed door 1 through the fixed slide groove 11;

[0025] Specifically, as a preferred embodiment of the present invention, the free end of the opening and closing motor 21 is fixedly mounted on the inner wall surface of the fixed door 1, the outer wall surface of the limiting iron post 33 is movably connected to the opening and closing door 24, and the movable door 34 is movably connected to the opening and closing door 24 via the limiting iron post 33;

[0026] The connection is firm and stable, and the distance of movement of the opening and closing door 24 is limited, so that the opening and closing effect is good. Moreover, through the setting of the movable door 34, it can also be rotated ninety degrees, so that the evacuation door can be opened and closed horizontally or rotated.

[0027] like Figure 1 and Figure 5 As shown, as a preferred embodiment of the present invention, the inner wall surface of the fixed door 1 is fixedly connected to a fixed rod 12, the outer wall surface of the fixed rod 12 is slidably connected to a fixed block 13, and the lower end surface of the movable door 34 is rotatably connected to the fixed block 13;

[0028] Specifically, as a preferred embodiment of the present invention, the drying structure 36 includes a drying motor, the output end of the drying motor is connected to a rotating shaft, the end surface of the rotating shaft is fixedly connected to a drying fan, the lower end surface of the opening and closing door 24 is provided with an air outlet 301, and the upper end surface of the opening and closing door 24 is provided with an air inlet filter hole 302;

[0029] The movable door 34 is supported and its stability during rotation is increased, and it is also limited after rotation. Moreover, through the arrangement of the air inlet filter hole 302, the air outlet hole 301 and the heating wire 37, water stains or ice cubes on the surface of the evacuation door can be dried, thereby reducing the impact on the opening and closing of the evacuation door.

[0030] like Figure 3 As shown, as a preferred embodiment of the present invention, the width of the opening and closing door 24 is greater than that of the movable door 34, the height of the triangular scraper 4 is the same as that of the movable door 34, and the number of the triangular scraper 4 is two groups, which are respectively installed on the front inner wall and the back inner surface of the fixed door 1;

[0031] The force of the triangular scraper 4 can be used to scrape off the debris adhering to the surface of the movable door 34 when it moves horizontally, thereby reducing the probability of the debris being collected into the fixed door 1 and causing blockage.

[0032] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
