Embodiment

Illustrated embodiment is described further to the technical solution of the utility model below in conjunction with the accompanying drawings.

The utility model emergency door stairs, its structure includes the four consistent vertical ladders of section length, respectively upper section vertical ladder 1, on Save vertical ladder 2, in lower section vertical ladder 3 and lower section vertical ladder 4, upper section vertical ladder 1 upper section vertical ladder 2 be connected by cutting with scissors mounting mechanism, in upper section The lower section vertical ladder 3 with of vertical ladder 2 be connected by cutting with scissors mounting mechanism, in lower section vertical ladder 3 be connected with the lower vertical ladder 4 that saves by cutting with scissors mounting mechanism, respectively The flip angle for locking hinge vertical ladder two-by-two in mounting mechanism provided with rotation preventive mechanism is cut with scissors, as shown in Figure 1, Figure 2, shown in Fig. 3, Fig. 4, Fig. 5.

The hinge mounting mechanism is as shown in fig. 6, rotation preventive mechanism therein is the card wheel 9 in rotating shaft, and the axial direction of the card wheel 9 is moved The dynamic latch that can make in card wheel 9 be engaged neck on pivoted housing or with the exact separation on pivoted housing.

Each vertical ladder includes left and right handrail 5 and pedal 6, the equi-spaced apart of pedal 6 and is installed in rotation on left and right help On hand 5, it can be made to close between left and right handrail 5 and (be existed together a plane with left and right handrail 5) varus of pedal 6 manually, manually Pedal 6, which is turned up, can make it vertical on left and right handrail 5, can be real by link gear connection between each pedal 6 of four section vertical ladders Existing synchronous varus and valgus, as shown in Fig. 1 Fig. 2, Fig. 3, Fig. 4, Fig. 5.

The link gear is steel wire rope draw-off mechanism, as shown in fig. 7, then being driven by pushing pedal turnover clamp pin 10 Pedal turns down the compression spring 12 of clamp 11, thus pull steel wire rope 14 will translate into outside each pedal 6 it is vertical with handrail 5, to avoid saving The upset of vertical ladder between section and the change for causing steel wire rope 14, steel wire rope 14 pass through at the rotation of handrail 5 of the section with section vertical ladder Middle wiring 13 is attached, as shown in Figure 6.

The most higher level pedal 6 of upper section vertical ladder 1 is fixedly mounted on left and right handrail 5 in varus shape and as fixed plate, this is consolidated It is respectively equipped with left and right hook 7 on the inside of fixed board, fixed plate inner hollow is simultaneously deposited and has safety rope；The left and right handrail 5 of upper section vertical ladder 1 Top and the bottom of left and right handrail 5 of lower section vertical ladder 4 are equipped with roller 8, and the roller 8 passes through manually adjustable telescoping mechanism Inside handrail 5, as shown in Fig. 2, Fig. 5.

Occupation mode of the present utility model is：

1st, when on the shelf, four section vertical ladders overturn overlapping (and locking) into " door leaf " shape successively, and being installed in doorframe to make Used for door, the varus of each pedal 6 closure now, each roller 8 is retracted in handrail 5.

2nd, when fire occurs for building, the four section vertical ladders of " door leaf " shape can be removed from doorframe and deploys to be deformed into such as figure Four section vertical ladders, are hooked on building windowsill or balcony, out of most higher level's pedal 6 by " one " font Emergency Ladder shown in 2 with hook 7 Take out safety rope to be bundled in survivor, survivor goes downstairs along Emergency Ladder and can escaped, and each pedal 6 now turns up, respectively Roller 8 is retracted in handrail 5.

3rd, usually house when, change the bulb or take object as that need to ascend a height, the four of " door leaf " shape section vertical ladders can be taken from doorframe Under, by upper section vertical ladder 1, upper section vertical ladder 2 overturns (and locking) for " one " font with, and lower section vertical ladder 3 and lower section vertical ladder 4 are turned over by It is " people " font that locking state is formed between " one " font, two section " one " font vertical ladders to turn (and locking), as shown in figure 3, this When each pedal 6 turn up, each roller 8 is retracted in handrail 5.

4th, when coming earthquake, the four section vertical ladders of " door leaf " shape can be removed from doorframe, makes the overlapping upper He of section vertical ladder 1 In upper section vertical ladder 2 with it is overlapping in be turned into " triangle " shape of locking state and as steady between lower section vertical ladder 3 and lower section vertical ladder 4 Solid triangle shock-absorbing area, as shown in figure 4, the varus of each pedal 6 now, each roller 8 is retracted in handrail 5.

5th, when needing transhipment large item, the four section vertical ladders of " door leaf " shape can be removed from doorframe, upper section is straight by The lower section vertical ladder 3 with of ladder 2 overturns (and locking) for " one " font, and upper section vertical ladder 1 is downwardly turned over and saved on (and locking) Cheng Yuzhong Vertical ladder 2 is vertical, and lower section vertical ladder 4 is downwardly turned over and saves that vertical ladder 3 is vertical under (and locking) Cheng Yuzhong, as shown in figure 5, respectively stepping on now The varus of plate 6, each roller 8 manually stretch out outside handrail 5 by regulation.
