Specific embodiment
Referring to attached drawing, the utility model is described in further detail.
As shown in Figure 1 and Figure 4, a kind of people's air defense sealed door, including doorframe main body 3 and doorframe is rotatably connected on by free bearing 2
Door-plate 1 in main body 3, in the sliding rail of installation below ground and threshold 5 of doorframe main body 3, the upper surface of threshold 5 is concordant with ground.
The side slide 52 for being fixedly connected on 5 side of threshold is slidably connected in the first sliding groove 41 of sliding rail, and threshold 5 can be along sliding rail vertical
Side moves upwards.
As shown in Figure 2 and Figure 4, threshold 5 includes lower filling block 55, the side slide 52 positioned at lower 55 two sides of filling block, connection
The cross bar 51 of lower filling block 55 and side slide 52, the upper filling block 54 for being connected to 55 top of lower filling block and it is located at lower filling block
First sealing joint strip 53 of 55 upper surfaces.Upper filling block 54 can be just caught in the card slot 12 opened up below door-plate 1, lower filling
The width and length of block 55 be greater than upper filling block 54, conducive to threshold 5 positioning and increase its sealing performance.When threshold 5 is along sliding rail
On move to when being fixed with the card slot 12 on door-plate 1, cooperation reaches sealing effect on the downside of 53 door-plate 1 of the first sealing joint strip.Door simultaneously
Shown in sill 5 and card slot 12(Fig. 3) fix after also have the function of fixed door-plate 1, increase the explosion-proof capabilities of closed guard gate.
As shown in Figure 2 and Figure 5, shown in cross bar 51(Fig. 4) on be fixedly connected with connecting rope 8, can be by connecting rope 8 on the door
The force of sill 5 moves up threshold 5 along sliding rail.Side towards door close plate 1 in doorframe main body 3 be provided be located at it is sealed on door-plate 1
The height of part 11 equal clamping groove 6 is provided with the second sliding slot 61 extended along 6 depth direction of clamping groove, second sliding slot in clamping groove 6
61, towards being tilted inside clamping groove 6 down, slidably connect slide bar 62 in second sliding slot 61.Connecting rope 8 is from top around fixed sliding
It is connected after wheel 7 with the slide bar 62 in the clamping groove 6 in doorframe main body 3.Slide bar 62 and threshold 5 by fixed pulley 7 and connecting rope 8 into
Row linkage.
