Detailed description of the invention
Below in conjunction with specific embodiment, this utility model is done progressive explanation.Should be understood that following example are merely to illustrate this utility model not for limiting scope of the present utility model.
Embodiment 1
Fig. 1 is structure chart of the present utility model.
As shown in Figure 1, a kind of elevator landing door lock linkage structure includes: door lock interlocking bar 100, triangular key portion 200, layer door lock 300 and door lock connector 400, one end of door lock interlocking bar 100 is connected with layer door lock 300, and the other end of door lock interlocking bar 100 is connected with triangular key portion 200 by door lock connector 400.
Triangular key portion 200 includes: triangular key 210 and triangular key connecting plate 220, and triangular key 210 is connected with one end of triangular key connecting plate 220, and the other end of triangular key connecting plate 220 links with door lock connector 400.
Door lock connector 400 includes: connector 410 and connecting hole 420, connector 410 be provided with connecting hole 420 with, connector 410 is connected with door lock interlocking bar 100, and connecting hole 420 is connected with triangular key connecting plate 220.
The main door lock installation structure used on current elevator door, door lock re-packs and is connected on door lock, and triangular key re-packs and is arranged in triangular key.It is respectively at disconnected position owing to door lock re-packs to re-pack with triangular key, and when in layer every fan height change situation or layer door machine installation site higher etc., this structure is likely to cause triangular key to re-pack and door lock re-packs loose contact, and the behavior that occurs to unblank smoothly safely.
This utility model makes door lock and triangular key be in connection status by door lock connector, increases door lock and opens the structure that linkage is more flexible, reliable and secure.
Concrete principle is, directly drives triangular key connecting plate 220 when rotating triangular key 210, by connector 410, kinetic energy is passed to door lock interlocking bar 100, and layer door lock 300 brings up door lock motion by door lock interlocking bar 100 and reach door interlock switch action.
Above detailed description of the invention of the present utility model being illustrated, but this utility model is not limited thereto, without departing from objective of the present utility model, this utility model can also have various change.
