Description
Technical field
The present invention relates to the technical field of elevator, particularly to a kind of door lock dress of manually opened layer door in pit
Put.
Background technology
During elevator maintenance, personnel's pit to be entered, but due to door-opened elevator width and the shadow of height
Ringing, the personnel in pit cannot touch door-lock opening layer door safely by pit ladder, makes the personnel in pit stranded, may
The life security of personnel in pit can be threatened, during it addition, personnel are operated by pit ladder, there is the phenomenon of operating difficulties,
And the operation on pit ladder, itself there is also danger.
Summary of the invention
The purpose of invention: the present invention discloses a kind of door lock assembly of manually opened layer door in pit, it is simple in pit
Personnel open layer door, and push rod only need to be caught up one to push away, it is not necessary to any loaded down with trivial details item, just can safety opening door lock,
Open layer door.
Technical scheme: in order to realize object above, the invention discloses a kind of door of manually opened layer door in pit
Locking device, including latch hook, tapered end, door-plate end socket and layer door, also includes the push rod being vertically arranged, wherein push rod one end and tapered end phase
Connecting, the other end extends to layer door lower end.The personnel that this design is easy in pit open layer door, and push rod only need to be caught past
Upper one pushes away, it is not necessary to any loaded down with trivial details item, just can safety opening door lock, open layer door.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, described layer door is provided with fixing seat,
Push rod is also cross door-plate end socket and fixing seat.Effect that is spacing and that guide is played in this design, it is ensured that push rod contacts smoothly, pushes up
Unblank head, and prevent push rod double swerve, operate more stable, safety, and do not produce abnormal sound.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, described fixing seat is arranged on layer
The lower end of door.This design fixes push rod from the two ends of push rod respectively, two fixing point length spaced apart, the most steady
Fixed.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, described door-plate end socket is with fixing
Seat is respectively equipped with the collar, and the collar is set on push rod.This design can ensure that when personnel promote push rod, and push rod can be at set
Ring slides smoothly；And when naturalness, push rod, under the effect of collar frictional force, can keep resting state.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, described collar medial wall sets
There is one group of projection.This design can reduce the contact area of the collar and push rod, can suitably reduce frictional force, use less power
Just door lock can be opened；It addition, this design slow down the friction that push rod is overall with the collar, its service life can be improved.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, described one group of projection is ringwise
Array-like is distributed on the medial wall of the collar.This design makes force distribution uniform, operates more smooth and easy.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, the cross section of described projection in
Semicircle.This design makes in linear contact lay between projection and push rod, or superfine face contact, and the promotion that can make push rod is lighter
Pine.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, described push rod bottom is provided with handle
Hand.This design facilitates operator to grasp and operates, and operating position is more eye-catching, and operating handle is preferable.
Further, above-mentioned a kind of door lock assembly of manually opened layer door in pit, described push rod is provided with limited block,
Limited block is arranged on above fixing seat, is provided with spring between limited block and fixing seat.Push rod has been moved up and down by this design
To position-limiting action, the active force of push rod is possible to prevent push rod to open by mistake door lock and causes danger by spring.
Technique scheme is it can be seen that there is advantages that one of the present invention is for pit
In the door lock assembly of manually opened layer door, simple in construction, be easily achieved, it is simple to the human users in pit, only need to catch push rod
Up one push away, it is not necessary to any loaded down with trivial details item, just can safety opening door lock, open layer door；Operating position is eye-catching, and required dynamics is fitted
In, operating handle is preferable；It addition, operate more stable, safety, and do not produce abnormal sound.
