Detailed description of the invention
Referring to figs. 1 through Fig. 5, the utility model door lock of elevator embodiment is described further.
A kind of door lock of elevator, comprise active lock hook assembly and fixing jam plate assembly, described lock hook assembly comprises latch hook mainboard 10 and latch hook 8, described latch hook 8 is fixed on latch hook mainboard 10, described fixing jam plate assembly comprises a layer door lock base 2, reset attachment and swivel arm 3, what described swivel arm 3 was rotated by triangular key connecting rod 1 is fixed on layer door lock base 2, described reset attachment is fixed on layer door lock base 2, one end and the reset attachment of described swivel arm 3 are hinged, the other end of described swivel arm 3 is fixed with travel switch 7, described swivel arm 3 is provided with kink 31, described latch hook 8 is provided with electric touch panel 9, when described latch hook 8 offsets with kink 31, electric touch panel 9 and travel switch 7 contact.
The preferred travel switch of the utility model 7 is connected with electric read out instrument, certainly, travel switch 7 also can be connected with buzzer phone etc., layer door lock base 2 is arranged on the doorframe of layer door by welding or fastener, latch hook 8 is arranged on dodge gate by latch hook mainboard 10, when elevator is closed the door, dodge gate band moveable lock hook 8 moves towards swivel arm 3, in the process that latch hook 8 moves, latch hook 8 can contact with swivel arm 3, thus swivel arm 3 is rotated, at this moment reset attachment can produce the power impelling swivel arm 3 to reset, when layer door is not closed completely, certain distance is there is between electric touch panel 9 and travel switch 7, two contacts now on travel switch 7 is in off state, electric read out instrument can not closed by show elevator door, staff just can be learnt by electric read out instrument, thus elevator door is fastened, dodge gate is continued move towards the doorframe of layer door, latch hook 8 can move to kink 31 place of swivel arm 3, latch hook 8 does not contact with swivel arm 3, at this moment reset attachment will make swivel arm 3 rotate, thus kink 31 and latch hook 8 are offseted, and be arranged on swivel arm 3 due to travel switch 7, travel switch 7 also can be followed and rotate together, thus make the contact on travel switch 7 be compressed connection formation closure state by electric touch panel 9, electric read out instrument display layer door is closed, such people just can learn that layer door is closed completely, and now latch hook 8 and kink 31 offset, layer door closure.
The preferred reset attachment of the utility model comprises electromagnet assembly 4, spring bearing 14 and retracing spring 5, what described spring bearing 14 slided is fixed on control assembly, described retracing spring 5 is set on spring bearing 14, one end of described retracing spring 5 is fixedly connected with electromagnet assembly 4, the other end is fixedly connected with the sidewall of spring bearing 14, spring bearing 14 there is a perforate, swivel arm 3 offers aperture, rotary pin shaft 6 successively through hole and aperture, thus makes spring bearing 14 and swivel arm 3 realize hinged.
When door lock of elevator opened by needs time, can by inserting triangular key, triangular key is rotated, triangular key drives triangular key connecting rod 1 to rotate, thus makes triangular key connecting rod 1 drive swivel arm 3 to rotate, and latch hook 8 is threaded off and performs door opening action smoothly, instruction of opening the door can also be sent by sundry elevator control housing, control electromagnet assembly 4 to work, thus drive swivel arm 3 to rotate, latch hook 8 is threaded off.
And electric touch panel 9 is set is fixedly mounted on latch hook 8 by insulcrete 12, electric touch panel 9 and latch hook 8 are come by insulcrete 12 is isolated, thus the electric insulating guaranteeing between layer door and travel switch 7 is situated between and meet national standard requirement.
