Abstract
The invention relates to an elevator landing door opening and closing preventer which is composed of a triangular key, an upper stop block, a lower fixed block, a friction plate and a pin shaft. The triangular key is assembled on the upper stop block, through operating the triangular key, interaction of the upper stop block and the lower fixed block can be conducted, and the triangular key and the upper stop block can be detached. The triangular key and the preventer are integrally formed, when a landing door is opened, the elevator landing door opening and closing preventer can be placed on a landing sill groove conveniently, the open state of the landing door can be kept, and the operation is simple; the elevator landing door opening and closing preventer is provided with the friction plate which can increased frictional force, it is guaranteed that after door sheets are stopped by using the elevator landing door opening and closing preventer, the door sheets cannot be closed, and the safety and reliability are achieved.
Description
technical field:
The present invention relates to a kind of elevator door folding interceptor, belong to elevator technology field.
background technology:
Elevator carrying out debugging, overhaul, care work personnel are when needing to enter sedan-chair top, hoistway, elevator door must be opened, after personnel open elevator door, most cases needs that elevator door is held open state to operate.The method in the prior art elevator door being held open state has following several, and first: operating personal hand or pin stop the closedown of elevator door to operate, or have personnel to stop closedown personnel of elevator door to operate; Second: operating personal screwdriver, nipping pliers or other tool insertings enter on the downside of door-plate, utilize the friction force of instrument and sill that elevator door is held open state.To the first situation, if due to human users's error, very easily to crush, even shearing accident; To the second situation, because the friction force in general purpose tool and sill face is very unstable, elevator door cannot be held open state, also be easy to safety misadventure occurs.Owing to not having relevant art standard, technical requirements and operation tool to elevator door being held open state in the prior art, make operating personal carrying out debugging, overhaul, need cannot operate safely and effectively when elevator door being held open state when maintaining, there is very large potential safety hazard.
summary of the invention:
The technical matters that the present invention will connect solution is: provide a kind of at opening elevator layer behind the door, can the trapping layer door elevator door folding interceptor of closing, and triangular key can split with interceptor and is used alone.
In order to solve the problems of the technologies described above, the present invention is achieved by the following technical solutions: a kind of elevator door folding interceptor, comprise triangular key, described triangular key upper end comprises key bar, key bar is cylindrical structural and top is provided with key hole, described triangular key is connected on interceptor, described interceptor comprises stopper and lower fixed block, described upper stopper is that left end is provided with breach and middle part has the square structure of through hole, described lower fixed block is square structure and left end is provided with boss, described upper stopper and lower fixed block are by bearing pin active link, described triangular key is connected in the through hole in the middle part of stopper, and triangular key can be dismantled with upper stopper and be separated, friction lining is provided with bottom described lower fixed block.
As preferably, for the ease of the use of triangular key, in the middle part of described key bar, be provided with butterfly sheet; For the ease of adjusting the angle of inclination of upper stopper, key bar lower end is hemispherical dome structure.
Further, in order to increase the friction force between lower fixed block and sill groove, be fixedly connected with by flathead screw with friction lining bottom described lower fixed block.
Again further, the bottom surface of described friction lining is provided with friction net, and adopt friction web frame below friction lining, increase the friction force of friction lining and sill groove, failure-free trapping layer door closes more, and this structure is simple, easy to use.
Further, be supported on elevator door for the ease of upper stopper, described upper stopper right-hand member is arranged to featheredge structure and featheredge place has U-type groove.
Compared with prior art, the present invention by triangular key and interceptor integrated, open layer this device can be put into behind the door sill groove layer door is held open state time, operate very simple.This device is furnished with the friction lining increasing friction force, and after can guaranteeing to prop up door-plate with this device, door-plate can not cut out, safe and reliable.This device has filled up in prior art defect layer door being held open state and not requiring, uses this device can effective standard operation personnel, removes potential safety hazard.
accompanying drawing illustrates:
Below in conjunction with accompanying drawing, the present invention is further described.
Fig. 1 is the new axonometric drawing of this practicality.
Fig. 2 is k direction view of the present invention.
1, triangular key, 2, upper stoping block, 3, lower fixed block, 4, friction lining, 5, flathead screw, 6, bearing pin, 7, butterfly sheet, 8, key hole, 9, key bar, 10, U-type groove.
detailed description of the invention:
Describe the present invention below in conjunction with the drawings and the specific embodiments:
A kind of elevator door folding interceptor according to Fig. 1 and Fig. 2, comprise triangular key 1, described triangular key upper end comprises key bar 9, key bar 9 is for cylindrical structural and top is provided with key hole 8, described triangular key 1 is connected on interceptor, described interceptor comprises stopper 2 and lower fixed block 3, described upper stopper 2 is provided with breach and middle part has the square structure of through hole for left end, described lower fixed block 3 is for square structure and left end is provided with boss, described upper stopper 2 and lower fixed block 3 are by bearing pin 6 active link, described triangular key 1 is connected in the through hole in the middle part of stopper 2, and triangular key 1 can be dismantled with upper stopper 2 and be separated, friction lining 4 is provided with bottom described lower fixed block 3, be provided with butterfly sheet 7 in the middle part of described key bar 9, key bar 9 lower end is hemispherical dome structure, be fixedly connected with by flathead screw 5 with friction lining 4 bottom described lower fixed block 3, the bottom surface of described friction lining 4 is provided with friction net, described upper stopper 2 right-hand member is arranged to featheredge structure and featheredge place has U-type groove 10.
When using this device to open layer door, both triangular key 1 can be disassembled to be used alone and also can not dismantle triangular key 1 and directly use and open layer door.Open layer behind the door this device put into car door sill or landing sill groove and prop up door-plate, by butterfly sheet 7 clickwise in triangular key 1, upper stopper 2 is raised up to and touches door-plate lower end, this is fixed block 3 and friction lining 4 and sill groove tight friction at present, triangular key 1 is rotated to appropriate location, layer door can be held open state.When needing layer door to close, only needing the butterfly sheet in left-hand revolution triangular key 1 to take out package unit door-plate can close.
It is emphasized that: be only preferred embodiment of the present invention above, not any pro forma restriction is done to the present invention, every above embodiment is done according to technical spirit of the present invention any simple modification, equivalent variations and modification, all still belong in the scope of technical solution of the present invention.
