Description
Technical Field
The utility model relates to a people's air defense door.
Background
The modulus of people's air defense door of present conventional use is not conform to the garage modulus of commonly used, can lead to the local production of raising and a large amount of anti-beams of people's air defense structure roof, can produce the adverse factor or be unfavorable for arranging and influence roof water-proof effects of roof composite line to the net height of basement, probably causes the local seepage of roof. On the other hand, some civil air defense doors need to be provided with vent holes for ventilating fresh air inside the civil air defense engineering or ventilating and diluting toxic air after being invaded by the toxic air inside the civil air defense engineering.
Disclosure of Invention
The utility model aims to solve the above problem, provide a novel people's air defense door, specifically realize by following technical scheme:
a civil air defense door comprises a pair of door plates arranged in a door hole of civil air defense engineering, wherein at least one door plate is provided with a ventilation unit, and the ventilation unit comprises a cantilever rod, a sealing rod, a sleeve and a blocking piece; the door plate is provided with a mounting hole, and the hole wall of the mounting hole is provided with threads; the sleeve is in threaded connection with the mounting hole; the cantilever rod is fixedly connected to the inner side wall of the door panel and is positioned on one side of the sleeve; one end of the sealing rod is fixedly connected to the cantilever rod, the sealing rod horizontally extends to the interior of the sleeve, and the diameter of the sealing rod is smaller than the inner diameter of the sleeve; a retainer ring is fixedly arranged on the inner wall of the outer port of the sleeve, the baffle is fixedly arranged at the end part of the sealing rod and is opposite to the retainer ring, and the diameter of the baffle is larger than the inner diameter of the retainer ring; a limiting ring with the outer diameter larger than that of the mounting hole is arranged on the outer side of the end wall of the sleeve positioned on the inner side of the door plate; the width of door opening is 5500mm, and the height of door opening is 2200mm or 2800 mm.
The civil air defense door is further designed in that the diameter of the middle part of the sealing rod is smaller than that of the two ends of the sealing rod.
The civil air defense door, its further design lie in, the outer wall of door plant is provided with the circular shape seal groove that is located mounting hole periphery side, the outer end of sheathed tube turns over to be connected with the sealing washer, the sealing washer with the seal groove is relative.
The utility model has the advantages that:
the utility model is favorable for the arrangement of the civil air defense engineering roof comprehensive pipeline and the waterproof effect of the roof on the one hand, and avoids causing the local leakage of the roof; on the other hand, the ventilation unit in the ventilation hole has good sealing effect under the normal condition, and when the ventilation is opened, all adjusting parts are always connected to the door plate, so that the loss of related parts of the civil air defense door during long-term use is avoided.
Drawings
Fig. 1 is a schematic view of the overall structure of the embodiment of the present invention.
Fig. 2 is a schematic structural view of the ventilation unit.
Detailed Description
The invention is further described with reference to the drawings and examples in the following description:
a civil air defense door as shown in the drawings comprises a pair of door panels 9 arranged within the aperture of the civil air defense project, the width of the aperture being 5500mm and the height of the aperture being 2200mm or 2800 mm.
The embodiment adopts this structure to be favorable to arranging and roof water-proof effects of civil air defense engineering roof comprehensive pipeline, avoids causing the local seepage of roof.
Further, in the embodiment, at least one door panel 9 is provided with a ventilation unit, and the ventilation unit comprises a cantilever rod 1, a sealing rod 2, a sleeve 3 and a baffle 4; the door plate 9 is provided with a mounting hole, and the hole wall of the mounting hole is provided with threads; the sleeve 3 is in threaded connection with the mounting hole; the cantilever rod 1 is fixedly connected to the inner side wall of the door panel and is positioned on one side of the sleeve; one end of the sealing rod is fixedly connected to the cantilever rod, the sealing rod horizontally extends to the interior of the sleeve, and the diameter of the sealing rod is smaller than the inner diameter of the sleeve; a retainer ring 31 is fixedly arranged on the inner wall of the outer port of the sleeve 3, the baffle is fixedly arranged at the end part of the sealing rod and is opposite to the retainer ring, and the diameter of the baffle is larger than the inner diameter of the retainer ring; and a limiting ring 32 with the outer diameter larger than that of the mounting hole is arranged on the outer side of the end wall of the sleeve 3 positioned on the inner side of the door plate.
In a normal state, the sleeve longitudinally moves in the mounting hole by rotating the sleeve, so that the retainer ring is abutted against the outer ring of the baffle plate, and the baffle plate made of metal has certain elasticity, so that a better sealing effect is formed between the retainer ring and the baffle plate; when needs ventilation, the sleeve is rotated to the direction for the separation blade breaks away from with the retaining ring, thereby makes the inside wind channel that forms of sleeve.
The diameter of the middle part of the sealing rod is smaller than the diameter of the two ends of the sealing rod. The diameter of the middle part of the sealing sleeve just positioned inside is reduced, which is beneficial to reducing wind resistance under the ventilation condition.
In order to further enhance the sealing effect at the vent hole under the normal state, the outer wall of the door panel 9 is provided with a circular sealing groove 91 positioned at the outer peripheral side of the mounting hole, the outer end of the sleeve 3 is connected with a sealing ring 33 in a turning manner, and the sealing ring is opposite to the sealing groove.
The ventilation unit in the ventilation hole has good sealed effect under the normal state, and when opening the ventilation, all adjusting part remain throughout to be connected in the door plant, avoid the people's air defense door to lose in long-term use period relevant part.
