The specific embodiment

The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

with reference to Fig. 1~shown in Figure 3, the asynchronous door lock device of the utility model elevator, it comprises a cutter base plate 16, the movable blades assembly, the fixed blade assembly, coordinate with the fixedly lock 22 on being located at base plate 21 the active lock hook assembly that pins gate, described movable blades assembly is hinged with door cutter base plate 16, described active lock hook assembly is hinged with door cutter base plate 16, described active lock hook assembly comprises and is located at the press mechanism that is provided with movable latch hook 13 tops and is located at the second roller 14 that movable latch hook 13 below drive activity latch hooks 13 rotate, described fixed blade assembly is captiveed joint with door cutter base plate 16, it also comprises block 3, described block 3 is located between movable blades 1 in fixed blade 17 and movable blades assembly in the fixed blade assembly and captives joint with movable blades 1 middle part, described block 3 is provided with the dip plane 3.1 of rolling for the second roller 14 near fixed blade 17 1 side upper ends, described fixed blade 17 lower ends are connected by elastic component 18 with movable blades 1 lower end.Described dip plane 3.1 is clinoplane or inclination cambered surface, is clinoplane in the present embodiment.

Described movable blades assembly also comprises the first axle 2, the second axle 4, the 3rd axle 7, the first roller 5, upper connecting rod 6, lower link 19, described the first axle 2, the second axle 4 and the 3rd axle 7 are all captiveed joint with movable blades 1, described the first roller 5 and the 3rd axle 7 are rotationally connected, described upper connecting rod 6 one ends and lower link 19 1 ends are all hinged with door cutter base plate 16, described upper connecting rod 6 other ends and the second axle 4 are rotationally connected, and described lower link 19 other ends and the first axle 2 are rotationally connected.

Described block 3 is positioned in the middle of the first axle 2 and the second axle 4.

Press mechanism in described active lock hook assembly comprises stage clip fixed block 9, pressure cap 10, stage clip 11 and screw rod 15, described stage clip fixed block 9 is captiveed joint with fixed blade 17, and described screw rod 15 passes movable latch hook 13, stage clip 11, pressure cap 10 from the bottom up successively captives joint with stage clip fixed block 9.

Described movable latch hook 13 away from gib head one end be provided be located at base plate 21 on the electric connector 12 that coordinates of electric switch socket 20.

Described elastic component 18 is extension spring.

In the present embodiment, also be provided with the 4th axle 8 on described door cutter base plate 16, described active lock hook assembly and door cutter base plate 16 hinged referring to, described movable latch hook 13 is rotationally connected away from gib head end and the 4th axle 8.

As shown in Figure 4, when elevator door-motor opens the door (contain a machine normal initiatively open the door and door machine fault sedan-chair in take off two kinds of situations of door), driving link plate assembly 24 and the asynchronous door lock device of the utility model elevator is moved to the left, the first roller 5 rolls downwards along baffle plate 23 under elastic component 18 pulling force effects, and movable blades 1 clamps to fixed blade 17 and shrinks simultaneously.

As shown in Figure 5, continue in fixed blade 17 contraction processes at movable blades 1, the dip plane 3.1 of the block 3 on movable blades 1 contacts with the second roller 14, forces movable latch hook 13 upwards to rotate, the gib head of movable latch hook 13 is upturned, and the square hole that leaves in fixing lock 22 is opened.

As shown in Figure 6, when the door machine is in layer door onlocking zone, the rear movable blades 1 of croquet 25 on movable blades 1 and fixed blade 17 gripping layer door locks no longer shrinks, and movable latch hook 13 stays open state, and the asynchronous door lock device of the utility model elevator continues to move to L.H.flapped door with link plate assembly 24.

As shown in Figure 7; when the door machine is not in layer door onlocking zone; restriction without croquet 25 between movable blades 1 and fixed blade 17 can continue to shrink; until the second roller 14 has rolled the dip plane 3.1 of block 3; the second roller 14 leaves block 3, and movable latch hook 13 rotates under the application force of stage clip 11, and the gib head of movable latch hook 13 falls into again fixedly that the square hole of lock 22 catches on; stoped gate continue open, effectively protect passenger safety.

If break down after the elevator door-closing in-place, the elevator rescue personnel first drop to car layer door onlocking zone and rescue the people, under the croquet 25 on layer door lock is being subject to left propulsive effort effect, croquet 25 contacts with movable blades 1, and force the first roller 5 on the movable blades assembly to roll to left down along the inclined-plane on base plate 21, thereby being clamped to movable blades 1 under the extension spring effect, shrinks fixed blade 17.The dip plane 3.1 of the block 3 on movable blades 1 contacts with the second roller 14, forces movable latch hook 13 upwards to rotate, and movable latch hook 13 is opened.Due to the position-limiting action of croquet 25, movable latch hook 13 can continue to stay open state, and the asynchronous door lock device of the utility model elevator continues to move to L.H.flapped door with link plate assembly 24.

When the asynchronous door lock device of the utility model elevator is closed the door to the right when mobile with link plate assembly 24, the first roller 5 on the movable blades assembly contacts backward upper rolling with baffle plate 23, force movable blades 1 and fixed blade 17 distances increase and open, block 3 leaves the second roller 14, movable latch hook 13 rotates under stage clip 11 application forces, the gib head of movable latch hook 13 falls into fixedly that the square hole of lock 22 catches on, and maintains the lock status at door-closing in-place.
