Description
Technical field:
The present invention relates to mechanical field, relate in particular to elevator, particularly a kind of explosion-proof elevator landing door lock.
Background technology:
The environment for use of elevator is complicated, and long-time use, due to friction of motion heat-dissipating, makes the accessory temperature of elevator higher conventionally; Add elevator for the larger occasion of visitors flowrate, therefore higher to the security requirement of elevator accessory, the requirement of explosion proof of especially charged accessory.The layer door lock of elevator is that each floor all needs to arrange, and it is for carrying out reliable locking to the elevator door of some floors.Existing elevator door lock is only realized the locking of layer door, and does not consider the requirement of explosion proof of elevator to cause its safety not high.
Summary of the invention:
The object of the present invention is to provide a kind of explosion-proof elevator landing door lock, described this explosion-proof elevator landing door lock will solve the technical problem that in prior art, elevator landing door lock can not be explosion-proof.
This explosion-proof elevator landing door lock of the present invention is by mounting shell, opening hook, lock pin, latch hook, connecting rod, armature, electromagnetic coil, explosion-resistant enclosure and stuffing-box form, wherein, described armature and electromagnetic coil are all arranged in described explosion-resistant enclosure, explosion-resistant enclosure is arranged in described mounting shell by screw, one end of armature is stretched out from one end of explosion-resistant enclosure and is connected by bearing pin with one end of described connecting rod, connecting rod is connected with mounting shell by axle, between armature and explosion-resistant enclosure, be provided with sliding pair, on armature, be arranged with spring, spring is between explosion-resistant enclosure inner side and electromagnetic coil, described stuffing-box is arranged on the other end of explosion-resistant enclosure by bolt seal, wire is connected with electromagnetic coil by stuffing-box, opening hook front end is provided with opening, the rear end of opening hook is arranged in mounting shell by bearing pin, described lock pin is arranged in the opening of opening hook front end, described latch hook is shaft-like, the middle part of latch hook is arranged in mounting shell by lock shaft, the left end of latch hook is provided with hook, opening hook left side is provided with the joint portion of turning up, the joint portion of turning up coordinates with the hook of latch hook left end, the right-hand member of latch hook is connected with the other end of connecting rod by bearing pin.
Further, connecting rod is rectangular in shape, and the right angle portion of connecting rod is arranged on mounting shell by bearing pin.
Further, in the opening of opening hook, profile exit is provided with arc transition.
Further, the hook of latch hook left end is acute angle.
Further, the angle of the hook of latch hook left end is 60 °.
Operating principle of the present invention is: lock pin is connected with elevator door.Electromagnetic coil does not have in the situation of energising, and armature, due to the effect of spring, makes latch hook hook opening hook, lock pin is limited in the opening of opening hook.When electromagnetic coil is switched on, armature is because the effect of electromagnetic force moves right, and drivening rod clockwise rotates, connecting rod band moveable lock hook rotates counterclockwise, make opening hook depart from latch hook, now lock pin can freely be moved to the left, and the door being connected with lock pin is direction unlatching left also.
The present invention and prior art are compared, and its effect is actively with obvious.The present invention utilizes electromagnet armature to control the rotation of opening hook in elevator landing door lock, realizes the locking of elevator door and unblanks, and electromagnet is arranged on explosion-resistant enclosure inside, and elevator landing door lock can reach requirement of explosion proof, has improved the safety of layer door lock.
Accompanying drawing explanation:
Fig. 1 is the structural representation of a kind of explosion-proof elevator landing door lock of the present invention.
Fig. 2 is locking and the view of unblanking in the present invention.
The specific embodiment:
Embodiment 1:
As depicted in figs. 1 and 2, a kind of explosion-proof elevator landing door lock of the present invention, by mounting shell 12, opening hook 1, lock pin 2, latch hook 3, connecting rod 4, armature 5, electromagnetic coil 8, explosion-resistant enclosure 6 and stuffing-box 9 form, wherein, elevator door (not shown in FIG.) is connected with lock pin 2, described armature 5 one end are shaft-like, described armature 5 and electromagnetic coil 8 are arranged in described explosion-resistant enclosure 6, explosion-resistant enclosure 6 is arranged in mounting shell 12 by screw, armature 5 stretches out from explosion-resistant enclosure 6 one end and is connected by bearing pin with connecting rod 4 one end, between armature 5 and explosion-resistant enclosure 6, be provided with sliding pair along its length, on described armature 5, be arranged with spring 7, spring 7 one end are resisted against explosion-resistant enclosure 6 inner sides, explosion-resistant enclosure 6 other ends are provided with described stuffing-box 9 hermetically by bolt 11, wire 10 is connected with the electromagnetic coil 8 in described explosion-resistant enclosure 6 by described stuffing-box 9, described opening hook 1 front end is provided with slightly the opening that is " V " font, opening hook 1 rear end is arranged on mounting shell 12 by bearing pin, the opening of opening hook 1 front end matches with lock pin 2, latch hook 3 is shaft-like, latch hook 3 middle parts are arranged on mounting shell 12 by lock shaft, latch hook 3 left ends are provided with hook 301, opening hook 1 left side is provided with the joint portion 101 of turning up, hook 301 coordinates with the joint portion 101 of turning up, latch hook 3 right-hand members are connected with the other end of connecting rod 4 by bearing pin, connecting rod 4 middle parts are arranged in mounting shell 12 by bearing pin.
