Embodiment
Preferred embodiment of the present utility model is illustrated below in conjunction with accompanying drawing, it will be appreciated that described herein excellent
Select embodiment to be merely to illustrate and explain the utility model, be not used to limit the utility model.
Embodiment 1
As shown in Figure 1-2, the utility model provides a kind of elevator cage door locking apparatus, including hook plate 1, hits bow 2 and support
3, one end of support 3 is provided with catch bar 4, and one end of catch bar 4 is provided with skewed slot 5, and the top of support 3 is provided with safety contact
6, the top of safety contact 6 is provided with checking switch 7, and one end of checking switch 7 is provided with hook plate 1, and the top of hook plate 1 is provided with
Restorer 8, the bottom of hook plate 1 is provided with pulley 9, and pulley 9 is provided centrally with central shaft 10, and the outside of central shaft 10 is provided with
Chute 11, the side of hook plate 1, which is provided with, hits bow 2, and the one end for hitting bow 2 is provided with wheel card 12.
Further, restorer 8 is internally provided with spring 13, when 1 rotate counterclockwise of hook plate after, and the compression of hook plate 1 resets
Spring 13 in device 8, restorer 8, which is under pressure, to be deformed upon, after the thrust of catch bar 4 terminates, and the spring 13 after deformation is to hook
Plate 1 applies active force, it is recovered origin-location.
Support 3 is connected with hook plate 1 by safety contact 6 with checking switch 7, and hook plate 1 rotates counterclockwise drive checking and opened
Close 7 and leave safety contact 6, facilitate gate to drive lower open by door machine.
Hook plate 1 is connected with catch bar 4 by skewed slot 5, be easy to hook plate 1 wheel card 12 limitation be moved to the left when, skewed slot 5 with
The contact surface of the active force of hook plate 1 is inclined-plane, is easy to catch bar 4 after active force is applied to hook plate 1, hook plate 1 is with central shaft 10
Do counterclockwise movement in the center of circle.
Pulley 9 is connected with hitting bow 3 by taking turns card 12, when Men Jimen areas, and pulley 9, which is moved to the left, bumps against bow 2 one
The wheel card 12 at end, hook plate 1 does counterclockwise movement with central shaft 10 for the center of circle.
Specifically, when door machine starts, catch bar 4 promotes hook plate 1 to be moved to the left, and pulley 9 is moved to the left on chute 11,
When Men Jimen areas, the pulley 9 of the bottom of hook plate 1 is moved to the left under drive on chute 11, and pulley 9 is moved on chute 11
It more can guarantee that hook plate 1 is steady in moving process, central shaft 10 encounters the wheel card 12 for hitting 3 one end of bow in moving process, pushes away
Lever 4 still to the left, is moved to the left, power is acted on hook plate 1, promotes hook plate 1 with central shaft because wheel card 12 limits pulley 9
