The specific embodiment
To shown in Figure 5, door lock of elevator of the present invention is used for elevator door or gate, comprising as Fig. 1: door lock assembly A, the locked component B of locking elevator door, guarantee door-closing in-place assembly C, contact assembly D;
Door lock assembly A comprises pedestal 5, dead bolt 1, dead bolt guide 8,9, closes lock spring 10, is arranged at the lockhole on the two fan elevator doors 2,3 respectively; Dead bolt 1 is arranged on the pedestal 5, and the afterbody of dead bolt 1 connects an end that closes lock spring 10, and the other end that closes lock spring 10 is captiveed joint with pedestal 5; The both sides of dead bolt 1 are respectively equipped with dead bolt guide 8,9, dead bolt guide 8,9 is fixedly set on the pedestal 5, dead bolt guide 8,9 can lead to the sense of motion of dead bolt 1, and dead bolt 1 can only sway and can not move up and down under the restriction of the guiding of dead bolt guide 8,9; Lockhole on the elevator door 2,3 is aimed at the head of dead bolt 1; Door lock assembly A is used for directly locking elevator door 2,3.
Locked component B comprises locking piece 4, locking spring 11, is arranged on the lift car or the control mechanism 411 of stop side; Locking piece 4 is connected with pedestal 5 by axle, and locking piece 4 can be around this axle rotation; The back of locking piece 4 is connected with pedestal 5 by locking spring 11; Control mechanism 411 can make locking piece 4 rotations;
Locking piece 4 comprises guide wheel 41, ratchet 42, and when control mechanism 411 acted on guide wheel 41, locking piece 4 clickwises made ratchet 42 leave the bayonet socket of dead bolt 1, make locked component B release; When control mechanism 411 leaves guide wheel, and locking spring 11 is when acting on guide wheel 41, locking piece 4 left-hand revolutions, make ratchet 42 snap in the bayonet socket of dead bolt 1, this moment, locked component B was in the lock state, and dead bolt 1 is locked, thereby made door lock assembly A keep the positive lock state.
Locked component B is used to keep door lock of elevator to be in the lock state.Control mechanism 411 can be re-pack (or cam mechanism), also can be electromagnetic control mechanism.Control mechanism 411 switches locked component B by controlling the bayonet socket that ratchet 42 left or be pressed into dead bolt 1 between the locking and unlocking two states.Whether the locking of locked component B does not change the state of door lock assembly A, and locked component B does not change the lock-out state of elevator door when elevator moves.
Guarantee that door-closing in-place assembly C comprises the sliding pin 6,7, the sliding pin retracing spring 12,13 that have lockhole, is fixedly set in the block 17,18 on the elevator door 2,3;
The head of pedestal 5 is provided with guide groove, and slidably sliding pin 6,7 is arranged in the guide groove; Sliding pin 6,7 connects sliding pin retracing spring 12,13 respectively;
Guarantee that door-closing in-place assembly C makes door lock assembly A only when the elevator door door-closing in-place, its dead bolt 1 can be realized the locking to elevator door.
Electric switch D comprises the door contact that is arranged on each elevator door 2,3, the lock contact that is arranged at dead bolt 1 head; Electric switch D is used to confirm that elevator door door-closing in-place and dead bolt 1 insert all lockholes realization door lock lockings of elevator door.
Each fan door of elevator door is provided with door contact; The number of the lock contact on the dead bolt 1 equates with the sum of the door contact of elevator door.
Elevator door as shown in Figure 1 is a center opening door, and door contact 14 is set on the elevator door 3, and door contact 14 has two, is door contact 14a, 14b, two door contact 14a, 14b and elevator door 3 insulation but be interconnected.
Door contact 15 is set on the elevator door 2, and door contact 15 has two, is door contact 15a, 15b, two door contact 15a, 15b and elevator door 2 insulation but be interconnected.
Lock contact 16 on the dead bolt 1 has four, is lock contact 16a, 16b, 16c, 16d, locks contact and dead bolt 1 insulation for these four, and 16b is communicated with 16c.
The process that the present invention unblanks, opens the door is as follows:
When elevator cab movement to the flat bed zone, the control mechanism 411 of (or stop side) contacts and pushes open guide wheel 41 with the guide wheel 41 of locking piece 4 on the car at this moment, guide wheel 41 moves to right under the effect of control mechanism 411, makes ratchet 42 leave the bayonet socket of dead bolt 1, realizes the release of locked component B;
Dead bolt 1 is imposed to the right power (as making the dead bolt 1 stressed by modes such as handle or electromagnet are set) on dead bolt 1, dead bolt 1 overcomes the elastic force that closes lock spring 10 and moves right under the effect of external force, leave the lockhole of elevator door 2,3 respectively, and the lockhole of sliding pin 6,7, realize the unlatching of elevator door; Meanwhile door contact 14a, the 14b of electric switch D, 15a, 15b break away from lock contact 16a, 16b, 16c, 16d respectively, are the electric loop of end points thereby disconnect with contact 16a and 16d.
After dead bolt 1 leaves the lockhole of sliding pin 6,7, when elevator door is opened, the guide groove of sliding pin 6,7 on the effect lower edge of sliding pin retracing spring 12,13 pedestal 5 outwards moves two side shiftings of dead bolt 1 (promptly to), and sliding pin 6,7 blocks dead bolt 1 and makes door lock assembly A be held open state simultaneously.Therefore sliding pin 6,7 only can guarantee that dead bolt 1 just can carry out the locking of elevator door when the elevator door door-closing in-place; When elevator door not during door-closing in-place, dead bolt 1 is stopped by sliding pin 6,7 and can not lock elevator door.
The present invention closes the door, the process of locking is as follows:
Elevator door 2,3 cuts out under external force and when moving to certain position, the block 17,18 on the elevator door 2,3 moves inwardly into the afterbody of sliding pin 6,7 and contacts; In the process that elevator door 2,3 continues to move, block 17, the 18 promotion sliding pins 6,7 that move with elevator door 2,3 move inward (promptly close to dead bolt 1) together; When the elevator door door-closing in-place, the lockhole of sliding pin 6,7 heads is just aimed at the head of dead bolt 1 and the lockhole of elevator door 2,3, dead bolt 1 is moved to the left under the effect of closing lock spring 10, dead bolt 1 pass sliding pin 6,7 lockhole and and then insert lockhole on the elevator door 2,3, realize the locking of elevator door; Meanwhile, door contact 14a, the 14b of electric switch D, 15a, 15b contacts conducting with lock contact 16a, 16b, 16c, 16d respectively, and are that end points constitutes the series loop that is communicated with contact 16a and 16d, thereby affirmation door-closing in-place and locking are finished; Elevator operation then, the control mechanism 411 of (or stop side) separates with guide wheel 41 on the car, and locking piece 4 is left-hand revolution under the effect of locking spring 11, and ratchet 42 is snapped in the bayonet socket of dead bolt 1, realizes the locking of locked component B.
The present invention can realize the positive lock of elevator door.
