Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is preferred embodiment described in detail.
As it is shown in figure 1, the elevator door latch fitting that the present embodiment provides, it includes lock 1, clamping block 2, is rotatably arranged at lock
Latch hook 3 on seat 1, particularly, is provided with contact head 30 on latch hook 3, and door lock part also includes to match with contact head 30
Catalyst 4, the unlock piece 5 latch hook 3 and clamping block 2 being departed from and unlock for driving latch hook 3 to rotate, wherein catalyst 4 energy
Enough contact information is fed back to the control system that elevator is properly functioning, after latch hook 3 loses the stress that it is applied by unlock piece 5,
Latch hook 3 hook under the effect of deadweight is located on clamping block 2, and contact head 30 contacts with catalyst 4, and left and right layer door closes, and controls system
System assigns the instruction that car is properly functioning.
Therefore, one side is the most relative with latch hook 3 with clamping block 2 locks；On the other hand according to contact head 30 with contact
The contact information of device 4, thus show that left and right layer door is in fully closed condition, properly functioning for elevator provides safeguard, and prevents
Occur because layer door does not close caused contingency, meanwhile, also play the effect of duplicate protection.
Concrete scheme is as follows:
The offside door slide plate L and offside door slide plate R of elevator move respectively along the direction that layer door is opened or closed and are arranged on
On door slide rail G, clamping block 2 is fixed in any one among offside door slide plate L and offside door slide plate R, and lock 1 is fixing to be set
Put among offside door slide plate L and offside door slide plate R another on.
Concrete, clamping block 2 is fixed on offside door slide plate L, and lock 1 is fixedly installed on offside door slide plate R.
The hook portion of latch hook 3 is arranged down, and clamping block 2 is also in hook-shaped, and the hook portion stretching into latch hook 3 is meshed setting.
Further, the hook portion of latch hook 3 is the most extended and surface is provided with graduated scale, the end face of clamping block 2 and lock
The hook portion of hook 3 be arranged in parallel and with latch hook 3 depth of engagement more than or equal to 7mm.The first, guarantee mutually to hook, anti-locking hook；The
When two, making at a fully engaged, upper and lower latch hook keeps certain spacing, prevents hook dead, and cannot open normally.
Door lock part in this example also includes that the top being arranged on latch hook 3 enables to the return unit 6 that latch hook 3 resets.
Further, return unit 6 includes being positioned at and fixes door slide plate (offside door slide plate R) and the latch hook 3 of setting with lock 1
Between elastic component 60.It is to say, return unit 6 and latch hook 3 whole installation, when door slide plate moves, it is constantly in pressure
Contracting state.
Door lock part also includes being positioned at below latch hook 3 can answer urgent document or dispatch 7 with clamping block 2 departs from by jack-up latch hook 3.
Urgent document or dispatch 7 is answered to include the mounting seat 70 being fixedly installed on layer door frame, be arranged in mounting seat 70 and can transport up and down
Dynamic unloads rod 71 and unloads, with driving, the driving means 72 that rod 71 moves up and down.
Concrete, driving means 72 includes what the lock core of the triangulation chain 720 and triangulation chain 720 promptly opened the door was wholely set
Shifting part 721, wherein shifting part 721 rotates along with the rotation of lock core and can unload rod 71 upwards jack-up.
In this example, answer urgent document or dispatch 7 also include enabling to unloading rod 71 can automatically reset spring 73, when unload rod 71 to
During upper motion, spring 73 is in compressive state；After unloading excellent 71 stress losing shifting part 721, spring 73 recovers deformation, unloads
Lower excellent 71 reset.
As for unlock piece 5, it uses and the coordinating of gate left and right door cutter and roll wheel assembly so that latch hook 3 relatively rotates,
(in conjunction with accompanying drawing, when it unlocks, latch hook rotates counterclockwise), concrete structure is conventional design at elevators field, does not do at this in detail
Carefully state.
Above-described embodiment only for technology of the present utility model design and feature are described, its object is to allow and is familiar with technique
Personage will appreciate that content of the present utility model and implement according to this, protection domain of the present utility model can not be limited with this,
All according to this utility model spirit made equivalence change or modify, all should contain protection domain of the present utility model it
In.
