Specific embodiment
It is practical below in conjunction with this in order to make those skilled in the art more fully understand the technical solution of the utility model
Attached drawing in new embodiment, the technical scheme in the utility model embodiment is clearly and completely described, it is clear that institute
The embodiment of description is only the embodiment of the utility model a part, instead of all the embodiments.Based on the utility model
In embodiment, every other implementation obtained by those of ordinary skill in the art without making creative efforts
The range of the utility model protection all should belong in example.
As illustrated in figures 4-5, the anti-towing gear of a kind of elevator door of the present embodiment, including it is set to layer door board 1 and layer
Connecting rod 3 between door door pocket column 2, the elastic component 4 and safety switch 5 being mounted on landing door jamb column 2, elastic component 4
One end is connect with landing door jamb column 2, and the other end is connect with connecting rod 3, and multiple elastic components 4 are evenly distributed on connecting rod 3.Connecting rod 3
Width be less than gap between layer door board 1 and landing door jamb column 2, with guarantee will not when layer door board 1 is mobile
Touching connecting rod 3 leads to maloperation.Elastic component 4 in the present embodiment is spring.
The mounting plate 6 of landing door jamb column 2 is provided perpendicular on landing door jamb column 2, elastic component 4 is far from connecting rod 3
One end is mounted on mounting plate 6, to guarantee that compression and direction of extension and the direction of motion of connecting rod 3 of elastic component 4 are consistent, is protected
Demonstrate,prove the sensitivity of entire anti-towing gear.It is additionally provided on mounting plate 4 and the compression of elastic component 4 and stretching, extension side in the present embodiment
To consistent gag lever post, gag lever post is through setting in elastic component 4.
The anti-towing gear of elevator door in the present embodiment only includes a safety switch 5, and safety switch 5 is mounted on layer
Position of the door door pocket column 2 close to 3 lower end of connecting rod.In this way be arranged the reason of be since the object caused danger is mostly children,
Height is shorter, so safety switch 5 to be arranged close to the position of 3 lower end of connecting rod, to trigger peace in time when 3 activity of connecting rod
Full switch 5.
Safety switch 5 may be configured as multiple in some other embodiment, and multiple safety switches 5 are evenly distributed on layer door door
It covers on column 2, which position of connecting rod 3 no matter is touched in this way, safety switch 5 can be triggered in time, than by single peace
The position that full switch 5 is positioned close to 3 lower end of connecting rod is safer.And it can be by multiple safety switches 5 and multiple elastic components 4
It is arranged alternately, to guarantee the elastic restoring force of connecting rod 3 and trigger the sensitivity of safety switch 5.
The contact of safety switch 5 and 3 distance 5-20mm of connecting rod, retain certain buffer distance, prevent someone deliberately or
Careless touching connecting rod 3 leads to trigger safety switch 5 to force power failure ladder, causes the unnecessary wasting of resources.
Safety switch 5 in the present embodiment is switched using non-automatic-reset.It can be made using non-automatic-reset switch in connecting rod 3
After triggering safety switch 5, layer door board 1 stops door opening action to prevent causing further to injure, and elevator stops, it is necessary to artificial hand
Elevator can just continue to run after dynamic recovery switch, ensure that the safety of elevator operation.
Safety switch 5 is connect with the control system of elevator, can also be attached at elevator management.The triggering peace of connecting rod 3
After full switch 5, it is out of service that elevator control system controls elevator, and sends information at elevator management automatically, and accident treatment is complete
Bi Hou, after manually restoring safety switch 5, elevator control system control elevator is continued to run.
The course of work of the anti-towing gear of the elevator door of the present embodiment described briefly below:
After elevator runs to designated floor, layer door board 1 is opened, if there is children by hand sticker on layer door board 1 at this time
And have little time to recall, it is followed by the gap that layer door board 1 enters between layer door board 1 and landing door jamb column 2.The hand of children
Finger touches connecting rod 3, and connecting rod 3 is mobile to the direction far from children's torso, and compression elastic piece 4 simultaneously triggers safety switch 5, elevator control
It is out of service that system control floor door board 1 processed stops door opening action, elevator, also receives information at elevator management simultaneously, and according to
Actual conditions arrange processing mode such as to start rescue or alarm.After accident treatment, manual reversion safety switch 5, electricity
Ladder can restart to run.
As long as connecting rod is touched in above embodiments and triggers safety switch, the stopping that can causing layer door board to open
And the stopping of elevator, might not limit be children hand, other foreign matters are likely to result in the stopping of elevator.
A kind of anti-towing gear of elevator door of the present embodiment, it is reasonable in design, safety switch is triggered using connecting rod
Such mechanical device is come the risk that prevents clamp hand risk or foreign matter from entering, so as to protect the safety and elevator of passenger
It is reliable for operation, stability is high using safe, reduce the probability that risk occurs.
The above embodiments are only for explaining the technical ideas and features of the present invention, and its object is to allow be familiar with technique
Personage can understand the content of the utility model and implement accordingly, do not limit the protection scope of the present invention,
All equivalent change or modifications according to made by the spirit of the present invention essence, should all cover the protection scope of the utility model it
It is interior.
