Abstract
Disclosed is an automatic reset device of an elevator out-car door opening lock switching plate. The automatic reset device of the elevator out-car door opening lock switching plate comprises a movable locking hook (1), a static locking hook (2), a movable locking hook shaft (4), a lock switching rod head (5), a lock switching rod guide slot (6), a lock switching rod (7), a key shaft (8), a lock switching head (9) and a lock switching head slot (10). The key shaft (8) is connected with the lock switching head (9) inside the lock switching head slot (10), the lock switching head is connected with the lock switching rod (7), the lock switching rod (7) is connected with the lock switching rod head (5), the lock switching rod head is movably connected with the movable locking hook (1), the movable locking hook is connected with the static locking hook (2), the lock switching rod (7) is provided with the lock switching rod guide slot (6), a locking hook reset spring (3) is mounted above the movable locking hook, and a lock switching rod reset spring (11) is mounted at the bottom of the lock switching head slot (10). The automatic reset device of the elevator out-car door opening lock switching plate effectively avoids the problem that the lock switching rod cannot reset by self gravity, enables the locking hooks to reset normally and accordingly reduces elevator faults and accidents.
Description
Technical field
The utility model belongs to the add-on security device that elevator emergency is evacuated passenger, is that locking plate automatic reset device is dialled in the outward opening door of a kind of elevator hall specifically.
Background technology
Elevator hall's outward opening door is at present mainly that inner triangle key stirs at layer the unlatching that elevator door latch hook is realized layer door outdoors.When the dialling locking bar and dial bar guide channel vertical precision when not enough of door-opening mechanism, just there will be stuck phenomenon, causing dialling locking bar can not return by self gravitation.Thereby latch hook can not reset, just cause elevator faults or elevator accident.
Summary of the invention
The purpose of this utility model is the defect existing for prior art, providing a kind of solution to dial locking bar can not automatically resetly install, in elevator faults situation, emergency opening elevator place stop layer makes Room outward opening door dial the automatically reset device of locking plate energy behind the door, thereby reduces the generation of elevator faults or elevator accident.
The utility model is achieved by following technical solution: locking plate automatic reset device is dialled in the outward opening door of a kind of elevator hall, comprise movable latch hook (1), static latch hook (2), movable lock hook shaft (4, ) group lock rod head (5), dial bar guide channel (6), dial locking bar (7), key axle (8), dial tapered end (9), dial tapered end groove (10), key axle (8) connects group tapered end (9) of dialling in tapered end groove (10), dial tapered end (9) and connect group locking bar (7), dial locking bar (7) and connect group lock rod head (5), dial lock rod head (5) connection activity latch hook (1), movable latch hook (1) is connected with static latch hook (2), dial upper setting of locking bar (7) and dial bar guide channel (6), in movable latch hook (1) top, latch hook back-moving spring (3) is installed, poking lock head groove (10) bottom is provided with dials locking bar reset tension spring (11).
Owing to adopting technique scheme, locking plate automatic reset device is dialled in elevator hall's outward opening door that the utility model provides can effectively prevent from dialling the problem that locking bar can not return by self gravitation, latch hook can be able to normally be resetted, thereby reduce the generation of elevator faults or elevator accident.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
The movable latch hook of 1-in figure, the static latch hook of 2-, 3-latch hook back-moving spring, the movable lock hook shaft of 4-, 5-dials lock rod head, and 6-dials bar guide channel, and 7-dials locking bar, 8-key axle, 9-dials tapered end, and 10-dials tapered end groove, and 11-dials locking bar reset tension spring.
The specific embodiment
Now with regard to accompanying drawing, the utility model is further described.As Fig. 1, one group of locking bar reset tension spring 11, the normality of keep-spring when static are installed in poking lock head groove 10 bottoms.When with interior triangular form key twisting key axle 8, dial tapered end 9 and upwards rotate, drive to dial on locking bar 7 and move, dial the pressure that lock rod head 5 overcomes latch hook back-moving spring 3, back down movable latch hook 1, throw off with static latch hook 2, realize elevator door opening.Extract after triangular key, group downward pulling force of locking bar reset tension spring 11 just can make to dial after locking bar 7 overcomes it and dials the resistance between bar guide channel 6 and reset, and movable latch hook 1 resets under the effect of latch hook back-moving spring 3 simultaneously, completes elevator hall's outward opening door action.
