The limitation of novel protected scope.
The utility model provides a kind of cabin door open and close error protection mechanism, is applicable the rotary types such as aircraft boarding door, service door
Hatch door, as shown in figure 1, the cabin door open and close error protection mechanism includes linkage portion 1, limited block 2, lock part 3 and extension spring 4.
Linkage portion 1 is arranged in hatch door, and linkage portion 1 has side a and b, and wherein A ends are cut with scissors by first rotating shaft 11 and hatch door
Connect, the B ends of linkage portion 1 with and hatch door handle linkage connecting rod 9 be rotatablely connected；In the present embodiment, linkage portion 1 is a rocking arm, is shaken
The B ends of arm are cylindrical, and the B ends of rocking arm are provided with pin 12, and the B ends of rocking arm pass through pin 12 and the axis connection of connecting rod 9.
Limited block 2 is fixed in hatch door doorframe.
Lock part 3 is arranged in hatch door and is rotatablely connected by the second rotating shaft 31 with hatch door, and mistake proofing plate 3 is provided with hook
32, hook 32 and the B ends of linkage portion 1 are engaged, and the B ends for hooking linkage portion 1 after hatch door is opened fix it, lock part
The side of 3 close doorframe is provided with glider 33, and glider 33 and limited block 2 are engaged；In the present embodiment, 32 heads of hook
Horn shape block 34 is extended in outward flange to 32 outsides are linked up with, and causes card for hindering linkage portion 1 to cross hook 32 from outside when rotating
Extremely, chute 35 curved and with the second rotating shaft 31 for the center of circle, the length of chute 35 and the two of the rotation of hook 3 are provided with hook 3
Hold extreme position corresponding, cylindrical boss 5 is provided with hatch door, chute 35 and cylindrical boss 5 are engaged, and overall lock part 3 is in three
Angle tabular, wherein one jiao is hook 32, another angle is glider 33, and the one end for going back one jiao and extension spring 4 is mutually fixed, glider 33
For a roller.
The one end of extension spring 4 and hatch door are fixed, and the other end and lock part 3 are fixed, and extension spring 4 applies to lock part 3 and hatch door is opened
Direction identical power.
The operation principle of cabin door open and close error protection mechanism is as follows：
As shown in Figures 2 and 3, after hatch door is closed and is lockable, because hatch door handle drivening rod 9 moves
It is dynamic so that the B ends of linkage portion 1 are located at X position, and X position corresponds to position of the linkage portion 1 when hatch door pins, and due to hatch door at
In closed mode, therefore the limited block 2 on hatch door doorframe overcomes the pulling force of extension spring 4 to extrude the glider 33 of lock part 3, makes locking
The hook 32 in portion 3 turns to Y location, 32 position when hatch door is closed of the corresponding hook of Y location.
As shown in Figures 2 and 4, when needing to open hatch door, hatch door handle is rotated first to unlock hatch door, is rotating hatch door
During handle, connecting rod 9 moves with hatch door handle, drives connected pin 12 to move, and pin 12 drives linkage portion 1
B ends rotate around first rotating shaft 11, when hatch door handle turns to complete unlocked position from complete locked position, the B ends of linkage portion 1
Z location is turned to from X position, Z location corresponds to position of the linkage portion 1 when hatch door unlocks.Hatch door is rotated after hatch door unblock, is rotated
During, the power that the glider 33 of lock part 3 applies to limited block 2 is gradually reduced, while lock part 3 is also relative to second turn
Axle 31 rotates, and cylindrical boss 5 moves in chute 35, and extension spring 2 is also being gradually shortened, sliding when hatch door have rotated certain distance
Animal 33 leaves limited block 2, and extension spring 2 links up with 32 and also turn to Z location from Y location now to be most short, and Z location is simultaneously also right
32 positions after hatch door opening should be linked up with, 32 inward flange is now linked up with and hooks the B ends of linkage portion 1 and it is not rotated, i.e.,
Hatch door can not be pinned after hatch door opens certain distance, hatch door could be only pinned when hatch door is closed, is being protected
Hatch door is demonstrate,proved while lock part 3 can just lock only after normal switching-off, it is therefore prevented that when hatch door is closed, glider 33 with doorframe
The generation of the accident collision damaged condition of limited block 2.
When hatch door is not mounted on doorframe, hook 32 is maintained at Z location in the presence of extension spring 4, if now maloperation
During hatch door handle, the B ends of linkage portion 1 are rotated to 32 upper surfaces of hook and inconsistent with it, positioned at the angle of 32 outer edges of hook
Shape block 34 can prevent the B ends of linkage portion 1 cross hook 32 outward flanges, avoid hook 32 and linkage portion 1 between mutually it is stuck, together
When linkage portion 1 B ends can also overcome the pulling force of extension spring 4 to extrude hook 32, and make oneself first to reach Z location, now link up with 32 again
Z location is reached by the pulling force of extension spring 4, the hook 32 of special shape designs, it is ensured that hatch door (hatch door during installation and debugging
When being not attached to doorframe), hook 32, which will not be driven by linkage portion 1 to reverse rotation and excessive compression extension spring 4, causes its damage,
And Hui Shi error protections mechanism automatic unlocking and again on be locked into correct position, improve reliability.
It is described above, only specific embodiment of the present utility model, but the scope of protection of the utility model is not limited to
In this, any one skilled in the art is in the technical scope that the utility model discloses, the change that can readily occur in
Change or replace, should all cover within the scope of protection of the utility model.Therefore, the scope of protection of the utility model should be with described
Scope of the claims is defined.
