Connect, the other end extends to layer door lower end, and described layer door is provided with fixed seat, and push rod is also cross door-plate end socket and fixed seat, institute
State the lower end that fixed seat is arranged on layer door, described door-plate end socket and fixed seat are respectively equipped with the collar, and the collar is set on push rod.This
Kind of the personnel be easy in pit of design open layer door, and push rod only need to be caught up one to push away, need not any loaded down with trivial details item, just may be used
Safety opening door lock, open layer door.
Further, a kind of above-mentioned door lock assembly for layer door manually opened 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, with less power
Just door lock can be opened；In addition, this design slow down the push rod friction overall with the collar, its service life can be improved.
Further, above-mentioned a kind of door lock assembly for layer door manually opened 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 uniformly, and operation is more smooth.
Further, above-mentioned a kind of door lock assembly for layer door manually opened in pit, described raised cross section is in
Semicircle.This design makes to be in linear contact lay between projection and push rod, or superfine face contact, and the promotion of push rod can be made lighter
Pine.
Further, above-mentioned a kind of door lock assembly for layer door manually opened 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 for layer door manually opened in pit, described push rod is provided with limited block,
Limited block is arranged on above fixed seat, is provided with spring between limited block and fixed seat.This design having moved up and down to push rod
To position-limiting action, spring can prevent push rod from opening by mistake door lock the active force of push rod and cause danger.
Technique scheme can be seen that the present invention and has the advantages that：One kind of the present invention is used for pit
The door lock assembly of interior manually opened layer door, structure is simple, be easily achieved, and is easy to the human users in pit, only need to catch push rod
Up one push away, need not 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；In addition, operating more stable, safety, and do not produce abnormal sound.
