As shown in fig. 2, the explosion-proof door comprises a door body 1 and an explosion-proof device 2, wherein the door body 1 comprises a first steel plate layer 11, a heat-resistant layer 12, a heat-insulating layer 13, an anti-virus layer 14 and a second steel plate layer 15 which are sequentially arranged from inside to outside. Wherein the outer surface of the first steel deck 11 faces indoors and the outer surface of the second steel deck 15 faces outdoors.
The inner surface of the heat-resistant layer 122 is coated with heat-resistant concrete, so that high temperature generated by explosion is prevented from damaging the explosion-proof door, the heat-insulating layer 13 is internally fixed with heat-insulating nails, so that the explosion-proof door has the functions of heat resistance and heat insulation, and the gas-proof layer 14 is an activated carbon layer which is internally provided with activated carbon, so that toxic gas can be absorbed, and the toxic gas is effectively prevented from leaking;
the explosion-proof device 2 comprises a steel plate 21 and springs 22, the area of the steel plate 21 is smaller than or equal to the surface area of the door body 1, the number of the springs 22 is multiple, the springs 22 are arranged at equal intervals in an array mode, and the steel plate 21 is fixed on the outer surface of the first steel plate layer 11 through the springs 22.
Two relative facial surfaces of first steel sheet layer 11 and steel sheet 21 all are provided with a plurality of stoppers 23, set up in the stopper on first steel sheet layer 11 surface and set up in the stopper on steel sheet surface one-to-one setting, and each is a set of two relative phase blocks one to one, and every group stopper cooperation sets up a spring 22, and inside two stoppers of a set of stretched into respectively at spring 22's both ends to it is fixed with it. The explosion-proof device 2 is arranged, so that the impact power of the explosion generated indoors is weakened by the explosion-proof device 2, the explosion-proof door is difficult to deform, and the undeformed explosion-proof door is more convenient for later rescue.
Referring to fig. 1, the explosion door of the invention is a sliding door, and is characterized in that a guide rail head 3 is integrally arranged at the bottom of a door body 1, a guide rail groove 4 is concavely arranged on the bottom surface opposite to the bottom of the door body 1, the guide rail head 3 and the guide rail groove 4 are arranged in a matching manner, and the guide rail head 3 is transversely moved in the guide rail groove 4 to realize the opening and closing of the explosion door. And when the explosion happens, the arrangement of the guide rail head 3 and the guide rail groove 4 can also lighten the transverse impact force generated by the explosion, and reduce the possibility that the explosion-proof door is directly blown away.
Furthermore, in order to prevent the explosion door from being exploded during explosion, a limiting groove 5 is formed in the middle of the guide rail groove 4 inwards, a moving channel 6 is communicated with the interior of the door body 1 and the interior of the guide rail head 3, a limiting rod 7 is arranged in the moving channel 6, and the lower end of the limiting rod 7 is matched with the limiting groove 5. When the limiting rod 7 is matched with the limiting groove 5, the door body 1 is fixed and cannot transversely move, and the limiting rod 7 and the limiting groove 5 are arranged, so that the explosion-proof door is connected with the ground more fixedly, and the possibility of explosion of the explosion-proof door is greatly reduced.
In order to facilitate opening and closing of the transverse sliding door, a moving groove 8 is formed in the outer surface of the second steel plate layer 15, a pushing block 9 is fixed on the limiting rod 7, the pushing block 9 extends out of the outer surface of the second steel plate layer 15 through the moving groove 8, and the limiting rod 7 moves up and down.
When the door needs to be opened, the push block 9 is moved upwards, the push block 9 drives the limiting rod 7 to move upwards, the bottom of the limiting rod 7 is contracted into the guide rail head 3, and at the moment, the transverse moving door can move transversely, so that the explosion-proof door is opened; when the door needs to be closed, the explosion-proof door is transversely moved, the inner moving channel 6 of the explosion-proof door is communicated with the limiting groove 5, and the limiting rod 7 moves downwards under the action of gravity and finally is matched with the limiting groove 5, so that the explosion-proof door is closed.
When the explosion vent is opened in a translation mode, the limiting groove 5 is not communicated with the moving channel 6, the push block 9 can be loosened, even if the limiting rod 7 moves downwards under the action of gravity, the end part of the bottom of the limiting rod can be blocked by the guide rail groove 4, and the end part of the bottom of the limiting rod 7 is matched with the guide rail groove 4, so that the movement of the explosion vent cannot be influenced.
In order to prevent friction blockage between the guide rail head 6 and the guide rail groove 4, the outer surface of the guide rail groove 4 can be periodically coated with a lubricant, so that the explosion door can keep smooth transverse movement.
The above description is only a preferred embodiment of the present invention, and does not limit the present invention in any way. It will be understood by those skilled in the art that various changes, substitutions and alterations can be made herein without departing from the spirit and scope of the invention as defined by the appended claims.
