Description
Technical field
It the utility model is related to elevator technology field, and in particular to a kind of elevator door lock device.
Background technology
Door lock of elevator is to ensure the important component that elevator safety uses, and when carriage is not in level position, layer door needs to keep
Closure state, to prevent passenger's back drop road from casualty accident occur.
Elevator is correspondingly provided with a layer door lock per Men Jun layer by layer, ensures that layer door is in closure state by layer door lock.Layer door
Lock generally includes mechanical hook locking component and the electrical equipment of detection machinery hook locking component open or close state.
The many elevator doors lock to circulate currently on the market, it is electric although can ensure that layer door is in the state closed
Gas element uses exposed electrical contact, there is very big security risk.
For example, the patent of invention document of Publication No. CN103818809A discloses a kind of elevator door lock, by exposed
Electrical contact overlap joint outside realizes the detection function of electrical equipment, does not only exist security risk, and the installation and debugging of contact
It is inconvenient.
Elevator door lock common in the art is mutually clamped as shown in Figure 1, rotating latch hook 1 with fixed latch hook 4, locking
Layer door, in the state of layer door lock closes, the fixing electric contacts 3 rotated on the mobile electrical contact 2 and lock installing plate 5 of latch hook 1 are taken
Fetch connection circuit, using completely exposed sheet metal, the shield above sheet metal is only capable of blocking to be come from above fixing electric contacts 3
The thing that drops.
Mobile electrical contact moves from right to left during overlap joint, and lifting and latching with certain with latch hook
Rotation angle, be that right side needs reserved opening in shield, which is enough full to avoid the walking path of mobile electrical contact
Demand of the sufficient finger through touching sheet metal.
When people passes in and out carriage, since, there are gap, layer door lock is to meet the needs of locking a door general position between layer door and gate
In the gap of layer door and gate, maintenance staff and passenger are easy to touch fixing electric contacts by opening when stretching out one's hand upwards,
Since door lock safety return circuit voltage is mostly forceful electric power, it is easy to cause and electric shock casualty accident occurs.
In the prior art, the end of elevator door lock fixing electric contacts uses copper metal, and is parallel to each other equipped with conductive
Metal tabs, the surface of mobile electrical contact is generally using silvering contain, and inside is conductive copper metal block, movement electrical contact
Stent is insulating support.
During to ensure that rotating latch hook latches, mobile electrical contact be able to touch fixing electric contacts, and when mounted, fixed electricity touches
The metal tabs of head with respect to the horizontal plane upwarp certain angle, and the angle is excessive, easily make the argentiferous plating on mobile electrical contact surface
Layer abrasion, insulating support stress is excessive, causes mobile contact life to shorten；If angle too small, mobile electrical contact is be easy to cause
Overlap joint causes open circuit, loses a layer door lock function less than fixing electric contacts.
Above-mentioned door lock is used with inside as copper metal block, and outer surface is the mobile electrical contact containing silvering, and cost is higher,
And metal tabs upwarp angle need be accurately controlled, installation and maintenance replace accessory when it is all very inconvenient.
