Detailed description of the invention
Referring to figs. 1 through Fig. 5, door lock of elevator embodiment of the present invention is described further.
A kind of door lock of elevator, including active lock hook assembly and fixing jam plate assembly, described lock hook assembly includes latch hook mainboard 10 and latch hook 8, described latch hook 8 is fixed on latch hook mainboard 10, described fixing jam plate assembly includes a layer door lock base 2, resetting means and cursor 3, described cursor 3 is fixed on layer door lock base 2 by what triangular key connecting rod 1 rotated, described resetting means is fixed on layer door lock base 2, one end of described cursor 3 is hinged with resetting means, the other end of described cursor 3 is fixed with travel switch 7, described cursor 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, electrically touch panel 9 and travel switch 7 contact.
nullThe preferred travel switch of the present invention 7 is connected with electric display device，Certainly，Travel switch 7 can also be connected with buzzer etc.，Layer door lock base 2 is arranged on the doorframe of layer door by welding or securing member，Latch hook 8 is arranged on dodge gate by latch hook mainboard 10，Elevator is closed the door when，Dodge gate band moveable lock hook 8 moves towards cursor 3，During latch hook 8 moves，Latch hook 8 can contact with cursor 3，So that cursor 3 rotates，At this moment resetting means can produce the power promoting cursor 3 to reset，When layer Men Wei completely closes，Electrically there is a certain distance between touch panel 9 and travel switch 7，Now the two contacts on travel switch 7 is in off state，Electrically display device can be not turned off by show elevator door，Staff just can be learnt by electric display device，Thus elevator door is fastened；Dodge gate continues the doorframe towards layer door move, latch hook 8 can move at the kink 31 of cursor 3, latch hook 8 is not in contact with cursor 3, at this moment resetting means will make cursor 3 rotate, so that kink 31 offsets with latch hook 8, and owing to travel switch 7 is arranged on cursor 3, travel switch 7 also can be followed and rotate together, so that the contact on travel switch 7 is compressed connection by electric touch panel 9 and is formed closure state, electrically display device display layer door has been switched off, so people just can learn that layer door completely closes, and now latch hook 8 and kink 31 offset, layer door closure.
The preferred resetting means of the present invention includes electromagnet assembly 4, spring stack 14 and back-moving spring 5, what described spring stack 14 slided is fixed on control assembly, described back-moving spring 5 is set on spring stack 14, one end of described back-moving spring 5 is fixing with electromagnet assembly 4 to be connected, the other end is fixing with the sidewall of spring stack 14 to be connected, and spring stack 14 has a perforate, cursor 3 offers aperture, rotary pin shaft 6 sequentially passes through hole and aperture, so that spring stack 14 realizes hinged with cursor 3.
When door lock of elevator opened by needs when, can be by inserting triangular key, triangular key is made to rotate, triangular key drives triangular key connecting rod 1 to rotate, so that triangular key connecting rod 1 drives cursor 3 to rotate, makes latch hook 8 thread off smoothly and performs door opening action, enabling instruction can also be sent by sundry elevator switch board, control electromagnet assembly 4 to work, thus drive cursor 3 to rotate, make latch hook 8 thread off.
And electric touch panel 9 is set and is fixedly mounted on latch hook 8 by insulation board 12, make electric touch panel 9 and latch hook 8 be come by insulation board 12 isolation, so that it is guaranteed that the electric insulation between layer door and travel switch 7 is situated between meets national standard requirement.
One end of door lock base is provided with stopper slot 21, the stop screw 11 of slip it is provided with in described stopper slot 21, described stop screw 11 is fixing with cursor 3 to be connected, cursor 3 can drive stop screw 11 to rotate in stopper slot 21 during rotating, and by arranging the length of stopper slot 21, the rotational angle of cursor 3, and then the reliability service of guarantee cursor 3 can be controlled, prevent rotational angle excessive or too small.
Insulation board 12 realizes removably connecting by screw 13 with latch hook 8, when electric touch panel 9 goes wrong and needs repairing or change when, by backing out screw 13, so that insulation board 12 separates with latch hook 8, and electrically touch panel 9 is fixed on insulation board 12, at this moment electrically touch panel 9 also separates with latch hook 8, convenient disassembly.
The above is only the preferred embodiment of the present invention, and protection scope of the present invention is not limited merely to above-described embodiment, and all technical schemes belonged under thinking of the present invention belong to protection scope of the present invention.It should be pointed out that, for those skilled in the art, some improvements and modifications without departing from the principles of the present invention, these improvements and modifications also should be regarded as protection scope of the present invention.
