Specific embodiment
As depicted in figs. 1 and 2, a kind of door lock of elevator drawstring door opener described in the utility model, mainly by triangulation chain
Component 1, cable element 2, reset guide device 3 and tightrope unit 4 form.
The triangle lock set 1 is existing common door lock of elevator workpiece, is fixed on the door-plate 6 of elevator.
One end of the cable element 2 is connected with triangle lock set 1, and the other end is equipped with connector 21.
The installation site of the reset guide device 3 is located at the top of the triangle lock set 1, by mounting bracket 31,
Pilot sleeve 32 and compression spring 33 form：Pilot sleeve 32 is fixed on by mounting bracket 31 on the door-plate 6 of elevator, and is oriented to
The central axis of sleeve 32 on the door-plate 6 of elevator along parallel；Compression spring 33 is arranged in the inner cavity of pilot sleeve 32 and it
One end of one end contact pilot sleeve inner cavity.The connector 21 of the cable element other end is slidably arranged on pilot sleeve
Inner cavity in and the conflict of compressed spring and in the pilot sleeve inner cavity the other end；The rope body self-conductance of cable element
It penetrates to one end of sleeve and is connected after passing through compression spring with connector.
The other end of one end self- steering sleeve of the tightrope unit 4 is penetrated and is connected with connector 21, and the other end is then
It is connected with the swing rod 52 of door lock of elevator.
The course of work of the utility model is as follows：
When needing by triangle lock set 1 latch hook 51 of door lock of elevator to be made to make unlocking action, make triangulation chain group with external force
Part rotate, active force by cable element be transferred to connector be allowed to slide in pilot sleeve and make compression spring-compressed store
Energy；Meanwhile active force is also transferred to tightrope unit by connector, it is dynamic that the band driven fork swing of tightrope unit makes latch hook lift completion unlocking
Make.After external force disappears, then compress spring reset conflict connector and be allowed to reset.
When the latch hook of door lock of elevator is made to be used as lift hook action by other external force, which cannot be transferred by tightrope unit
To triangle lock set, therefore triangle lock set, still in original state, will not rotate action.
