Description
Technical field
The utility model relates to the elevator technology field, discloses a kind of elevator door locking device specifically.
Background technology
In existing elevator door lock, the spacing of elevator lock sharp-crested is by door lock stay bearing plate below spacing adjusting screw(rod) to be set, the continuous then up-and-down movement of regulating spacing adjusting screw(rod) is finished with the restriction lock sharp-crested anglec of rotation, as Fig. 1, its structure is complicated, cost is high, the adjusting accuracy is more undesirable, rate of breakdown is higher, thereby in case operation does not keep off the spacing adjusting screw(rod) of easy shake-up elevator door is opened under unnecessary situation, caused potential safety hazard.
Summary of the invention
The purpose of this utility model is to solve the defective that exists in the prior art, provides that a kind of installation is simple, safe in utilization, maintenance and inspection are convenient, effectively prevent the elevator door locking device that elevator door is opened that is caused by maloperation.
The utility model is achieved in that a kind of elevator door locking device, comprise croquet frame, door lock stay bearing plate, layer door contact, interlocking switch, lock sharp-crested, door lock main shaft, it is characterized in that: described door lock stay bearing plate is provided with at least two position-limited levers, described position-limited lever lays respectively at the both sides of door lock main shaft, the described lock sharp-crested back side is provided with limiting stopper, and the position of described limiting stopper is positioned at above or below the position-limited lever.
Described layer door contact is provided with movable sliding, and described layer door contact links to each other with described lock sharp-crested with screw by movable sliding, and when locking sharp-crested with the door lock main axis rotation, a layer door contact slides up and down by sliding tray.
Described position-limited lever is positioned at the both sides of door lock main shaft and staggers up and down on level attitude.
Described door lock stay bearing plate is provided with 2～4 position-limited levers.
Described lock sharp-crested and limiting stopper are connected as a single entity.
Described position-limited lever is perpendicular to the door lock stay bearing plate.
The outer surface of described position-limited lever is provided with the elastic caoutchouc packing ring.
2 of described position-limited levers are one group and cooperate with limiting stopper and to form a stop gear, when the lock sharp-crested drives the limiting stopper rotation during to a sideway swivel with the door lock main shaft, when limiting stopper contacts the position-limited lever of door lock main shaft one side, thereby because stopping of position-limited lever makes the stop motion of lock sharp-crested limit the rotational angle of locking sharp-crested; Equally, when the limiting stopper contrarotation contacts the position-limited lever of door lock main shaft opposite side, thus the rotational angle of this side of lock sharp-crested stop motion restriction lock sharp-crested.
The beneficial effects of the utility model are: the setting of position-limited lever and limiting stopper, make the anglec of rotation of lock sharp-crested the time obtain restriction with the door lock main axis rotation, the maloperation that has been produced when having avoided artificial manual regulation to lock the sharp-crested anglec of rotation, use more safe and reliable, and simple in structure, maintenance and inspection of the present utility model are convenient, cost is low, are easy to promotion and application.

Among the figure: 1, spacing adjusting screw(rod); 2, croquet frame; 3, door lock stay bearing plate; 4, layer door contact; 5, interlocking switch; 6, lock sharp-crested; 7, door lock main shaft; 8, position-limited lever; 9, limiting stopper; 10, sliding tray; 11, screw.
The specific embodiment
According to Fig. 1, the structure of prior art elevator door lock is that a spacing adjusting screw(rod) 1 is set below door lock stay bearing plate 3, and by the anglec of rotation that the lifting of regulating spacing adjusting screw(rod) 1 comes control lock sharp-crested 6, structure is complicated, the adjusting accuracy is more undesirable.
According to Fig. 2～5, the utility model comprises croquet frame 2, door lock stay bearing plate 3, layer door contact 4, interlocking switch 5, lock sharp-crested 6, door lock main shaft 7.Lock sharp-crested 6 links to each other with door lock main shaft 7, and croquet frame 2 is fixed on lock sharp-crested 6 and the end that door lock main shaft 7 links to each other, and door lock main shaft 7 is welded on the door lock stay bearing plate 7, locks on the sharp-crested 6 layer door contact 4 is housed.Described door lock stay bearing plate 3 is provided with to 2～4 position-limited levers 8, preferred 2, described position-limited lever 8 lays respectively at the both sides of door lock main shaft 7, described lock sharp-crested 6 back sides are provided with limiting stopper 9, described lock sharp-crested 6 is connected as a single entity with limiting stopper 9, the position of described limiting stopper 9 is positioned at above or below the position-limited lever 8, and limiting stopper 9 is positioned at the position-limited lever top in this example, as Fig. 3.Described position-limited lever 8 is positioned at the both sides of door lock main shaft 7 and staggers up and down on level attitude.Described position-limited lever 8 is perpendicular to door lock stay bearing plate 3.The outer surface of described position-limited lever 8 is provided with the elastic caoutchouc packing ring.Described layer door contact 4 is provided with movable sliding 10, and described layer door contact 4 links to each other with described lock sharp-crested 6 with screw 11 by movable sliding 10, and when lock sharp-crested 6 rotated with door lock main shaft 7, layer door contact 4 slided up and down by sliding tray 10.Sliding tray is set on the layer door contact 4 guarantees that the contact can slide up and down, the contact is fully contacted with interlocking switch 5.Thereby guarantee the unimpeded of circuit.
The utility model in use, when lock sharp-crested 6 drives limiting stopper 9 rotations during to a sideway swivel with door lock main shaft 7, when limiting stopper 9 contacts the position-limited lever 8 of door lock main shafts 7 one sides, thereby because stopping of position-limited lever 8 makes 6 stop motions of lock sharp-crested limit the rotational angle of locking sharp-crested 6, as Fig. 4; Equally, when limiting stopper 9 contrarotations contact the position-limited lever 8 of door lock main shaft 7 opposite sides, thus the rotational angle of lock sharp-crested 6 stop motions restriction lock sharp-crested 6 these sides, as Fig. 5.By the angle of rotation that position-limited lever 8 limits lock sharp-crested 6 is set, need not extra manual operation, make lock sharp-crested 6 reach the unlatching and the closure of automatic guidance elevator door, improved safety in utilization.
