Description
Technical field
Elevator safety door lock of the present invention belongs to elevators field, more particularly to a kind of elevator safety door lock.
Background technique
It is required in 5.2.2.1.2 in standard GB/T 7588-2003: when the distance between adjacent two layers gate sill is greater than 11m
When, hoistway safety door should be set therebetween, to ensure the distance between adjacent sill no more than 11m；Hoistway safety door should be installed and use key
The lock that spoon is opened also can be turned off and lock without key after door is opened；Even if hoistway safety door in latching,
Should be able to not have to key to open door inside hoistway yet.And the production that existing safety door lock has does not meet national standard；Have
Just with one common door lock, then plus an electric switch, cannot detect whether lock tongue is effectively closed, to the safety of elevator
Operation leaves hidden danger.
Summary of the invention
It is an object of the invention in place of avoiding the deficiencies in the prior art, and a kind of detectable lock tongue is provided and whether is effectively closed
It closes, and elevator safety door lock that meet national standards.
The purpose of the present invention is what is reached by following measures, box body is set and fixing seat, box body are mounted on door-plate,
Safety contact is provided in fixing seat, threaded fixing sleeve is inserted into door-plate, and the fixed threaded fixing sleeve of thin nut, axis connects
It connects on lock core, bar is made in axis connection unlocking, and rubber sheet gasket is mounted on threaded fixing sleeve, and compression bullet is cased on bolt component
Spring, rotating handle connect bolt component, and lock core connection, which is unlocked, makes bar, and bar connection bolt component is beaten in unlocking.
Safety contact is provided in fixing seat.One of axis is triangle on lock core.
Bolt component can stretch under external force, and compressed spring can be such that bolt component resets.Lock tongue, which shortens, relies on external force
To drive, extends and rely on the effect of compressed spring then to drive.The fixing seat of one contact-carrying is mounted on the doorframe of safety door,
When the lock tongue of free extension elongation insertion fixing seat, safety door is just fastened, and the lock tongue of free extension and contact-carrying are consolidated
Reservation contact, connects the safety return circuit of elevator, elevator can operate normally.When maintenance personal opens in elevator shaft external application triangle key
When opening safety door, the lock tongue of retractable leaves the fixing seat of contact-carrying, and safety door is openable, and safety return circuit disconnects, elevator
It cannot run.When maintenance personal is in hoistway, rotating handle on rotatable door lock, rotating handle drives lock tongue to leave band touching
The fixing seat of point, safety door is also openable, and safety return circuit disconnects, and elevator cannot be run.
The configuration of the present invention is simple, at low cost, easy for installation, wide adaptability.
Detailed description of the invention
Attached drawing 1 is structural front view of the invention.
Attached drawing 2 is the structure left view of the invention.
Attached drawing 3 is structure top view of the invention.
In figure: 1, fixing seat, 2, safety contact, 3, box body, 4, axis, 5, threaded fixing sleeve, 6, rubber sheet gasket, 7, thin
Nut, 8, bolt component, 9, compressed spring, 10, rotating handle, 11, unlock make bar.
Specific embodiment
The present invention will be further explained below with reference to the attached drawings.
As shown in attached drawing 1, attached drawing 2, attached drawing 3, box body 3 and fixing seat 1 is arranged in the present invention and lock core I, box body 3 are mounted on work
On dynamic door-plate, fixing seat 1 is mounted on doorframe and is provided with safety contact 2, and threaded fixing sleeve 5 is inserted into door-plate, and is led to
The fixed threaded fixing sleeve 5 of thin nut 7 is crossed, axis 4 is rotatable in fixing sleeve, and the connection of axis 4, which is unlocked, makes bar 11, axis on lock core
One is triangle, and rubber sheet gasket is mounted on threaded fixing sleeve, and compressed spring 9 is cased on bolt component 8, rotates hand
Handle 10 can drive bolt component 8 mobile.Fixing seat 1 with safety contact 2 is mounted on the doorframe of safety door, and box body 3 is mounted on
On safe door board corresponding with elevator shaft interior wall, it can be rotated with door-plate around door loose-leaf, the portion I is the lock of safety door lock
Core is mounted on safe door board corresponding with elevator shaft exterior wall, and lock core rotation can drive bolt component 8 flexible.Axis 4 is can
The axis of 180 degree rotation, the portion I are inserted into door-plate by threaded fixing sleeve 5, fixed with thin nut 7 afterwards, and bolt component 8 can be
It stretches under external force, compressed spring 9 can be such that bolt component 8 resets, when maintenance personal enters axis 4 in hoistway external application triangulation chain key case
Afterwards, and rotary triangle key, triangle key drive axis 4 to rotate, and axis 4, which drives to unlock, plays the rotation of bar 11, and bar 11 is made in the unlocking of rotation
Drive bolt component 8 mobile, until bolt component 8 is detached from the fixing seat 1 with safety contact 2, safety door is openable, safety return circuit
It disconnects, elevator cannot be run.When maintenance personal rotates rotating handle 10 in hoistway, rotating handle 10 drives bolt component 8
Mobile, until bolt component 8 is detached from the fixing seat 1 with safety contact 2, safety door is also openable, and safety return circuit disconnects, and elevator is not
It can operation.When firmly closed safe door, bolt component 8 shortens compressed spring under external force, when safety door closes in place
Afterwards, bolt component 8 is extended by the effect of compressed spring, is inserted into the fixing seat 1 with safety contact 2, safety door is just fastened, and is connect
Be powered terraced safety return circuit, and elevator can operate normally.
