Based on the embodiment in the utility model, all other embodiments obtained by the ordinary skill in the art without creative labor are within the protection scope of the utility model.

[0028] The utility model embodiment provides a kind of fireproof and smokeproof safety door, including first door body 1 and second door body 2, exemplary, as shown in Figures 1-7 .

[0031] The moving rod 714 is slidingly connected to the inner side of the limiting block 715, the outer side of the moving rod 714 is provided with a limiting block 7161, the inner side of the connecting door plate 4 is fixedly connected with a second spring 77, one end of the second spring 77 is fixedly connected with a blocking block 78, the blocking block 78 is slidingly connected to the inner side of the sliding groove 6, one side of the blocking block 78 is fixedly connected with a fixed block 7163, one side of the fixed block 7163 is fixedly connected with a first spring 7162, and one end of the first spring 7162 is fixedly connected with the limiting block 7161.

[0032] Specifically, the connecting door plate 4 can be used to connect the first door body 1 and the second door body 2, and the first smoke-proof mechanism 71 and the second smoke-proof mechanism 72 can block the smoke generated when a fire occurs, thereby reducing the spread of smoke. Since the first smoke-proof mechanism 71 and the second smoke-proof mechanism 72 have the same structure, they have the same working principle, and therefore will not be described in detail here.

[0033] In addition, the rotation of the rotating disc 8 can drive the rotating rod 712 to rotate and move through the fixed ring block 711, and because the limiting block 715 limits the movement of the moving rod 714, the moving rod 714 can be pulled by the rotation of the rotating disc 8. When the moving rod 714 moves towards the side close to the rotating disc 8, it can press the limiting block 7161 to move to both sides.

[0034] In addition, after the limiting block 7161 moves to a certain distance, the connection between the limiting block 7161 and the moving rod 714 is cancelled, at this time the second spring 77 can push the blocking block 78 to move by elasticity, thereby blocking the door gap and reducing the spread speed of the smoke. The side of the limiting block 7161 close to the rotating disc 8 is provided with an inclined surface.

[0035] The length of the moving rod 714 in the first smoke-proof mechanism 71 is greater than the length of the moving rod 714 in the second smoke-proof mechanism 72, and the length of the blocking block 78 in the first smoke-proof mechanism 71 is less than the length of the blocking block 78 in the second smoke-proof mechanism 72, as shown in Figures 1-7 .

[0036] The inner sides of the first door body 1 and the second door body 2 are fixedly connected with reinforced steel plates 141, the outer sides of the two reinforced steel plates 141 are provided with fireproof gypsum 144, the inner sides of the first door body 1 and the second door body 2 are fixedly connected with aluminosilicate fiber layers 143, the aluminosilicate fiber layers 143 are provided on one side of the reinforced steel plate 141, and the other side of the reinforced steel plate 141 is fixedly connected with a polystyrene layer 142.

[0037] One side of the limiting block 7161 is fixedly connected with a limiting rod 101, one end of the limiting rod 101 penetrates through a fixed block 7163, and the limiting rod 101 is slidingly connected to the inner side of the fixed block 7163.

[0038] Specifically, the moving rod 714 in the first smoke prevention mechanism 71 is different in length from the moving rod 714 in the second smoke prevention mechanism 72, so that the blocking block 78 in the first smoke prevention mechanism 71 and the blocking block 78 in the second smoke prevention mechanism 72 can be smoothly used, and the first smoke prevention mechanism 71 or the second smoke prevention mechanism 72 is not prone to the situation of being unable to be smoothly used due to different lengths and widths of doors.

[0039] In addition, the lengths of the plurality of blocking blocks 78 are different, which can further effectively shield the door gap, and the reinforcing plate 141 can reinforce and strengthen the first door body 1 and the second door body 2, so that the first door body 1 and the second door body 2 are sufficiently solid during use, and the polystyrene layer 142, the aluminum silicate fiber layer 143 and the fireproof gypsum 144 can effectively play a fireproof role, reduce the speed of fire spread, thereby increasing the escape time for people.

[0040] In addition, the limiting rod 101 is provided, so that when the limiting block 7161 moves due to the movement of the moving rod 714, the movement of the limiting block 7161 is not prone to tilting, shaking and the like, thereby increasing the stability of the limiting block 7161 during movement.

[0041] One end of the limiting rod 101 is fixedly connected with a limiting ring block 102, and the diameter of the limiting ring block 102 is greater than the diameter of the limiting rod 101, as shown in Figures 1-7 .

[0042] The inner side of the connecting door plate 4 is provided with a connecting groove 121, the inner side of the connecting groove 121 is provided with a servo motor 122, the output end of the servo motor 122 is fixedly connected with one side of the rotating disc 8 through a shaft coupling, one side of the first door body 1 and the second door body 2 is provided with a smoke detector 11, and the two smoke detectors 11 are electrically connected with the servo motor 122.

[0043] One side of the blocking block 78 in the first smoke prevention mechanism 71 is fixedly connected with an extension block 131, one side of the blocking block 78 in the second smoke prevention mechanism 72 is provided with a hollow groove 132, the extension block 131 is slidingly connected to the inner side of the hollow groove 132, and one side of the blocking block 78 is fixedly connected with a filling block 9.

[0044] Specifically, the diameter of the limiting ring block 102 is greater than the diameter of the limiting rod 101, which can effectively prevent the limiting block 7161 from moving too far due to the elasticity of the first spring 7162 when the moving rod 714 no longer limits the limiting block 7161, so that when the blocking block 78 is accidentally touched in daily life, the moving rod 714 and the limiting block 7161 can be reset smoothly through the movement of the moving rod 714 and the inclined surface on one side of the limiting block 7161, and the limiting block 7161 is not prone to resetting.

[0045] In addition, the servo motor 122 can effectively drive the rotating disc 8 to rotate through its own operation, so as to realize the use of the first smoke prevention mechanism 71 and the second smoke prevention mechanism 72, and the smoke detector 11 can detect the smoke in the environment, so that when a large amount of smoke occurs, the alarm can be sounded and the servo motor 122 can be started.

[0046] In addition, the extension block 131 is provided, so that the plurality of blocking blocks 78 can fill the door gap more comprehensively when filling the door gap, and there is no large gap, thereby further improving the effect of blocking the door gap, and the filling block 9 can further reduce the gap between the door gap.

[0047] The working principle of the fireproof and smokeproof safety door according to the embodiment of the utility model is as follows: when the device is used, the smoke in daily life can be detected by the smoke detector 11, when the smoke in the environment is large, the smoke detector 11 will sound an alarm and start the servo motor 122, the servo motor 122 will drive the rotating disc 8 to rotate when operating, and the rotating disc 8 will drive the rotating rod 712 to move through the fixed ring block 711, and the limiting block 715 will limit the movement of the moving rod 714, so that the moving rod 714 will move towards the side close to the rotating disc 8, thereby canceling the limitation of the limiting block 7161, and at this time the second spring 77 will drive the blocking block 78 to move away from the side of the rotating disc 8 through the elasticity of the second spring 77, thereby realizing the filling and blocking of the door gap, and the blocking of the smoke, and reducing the spreading speed of the smoke, and the polystyrene layer 142, the aluminum silicate fiber layer 143 and the fireproof gypsum 144 can effectively play a fireproof effect, thereby increasing the opportunity and time for people to escape.

[0048] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced equivalently, and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the utility model.
