Description
Technical field
The utility model is related to a kind of plant equipment, especially a kind of protective door linkage lock construction.
Background technology
Protective door is a kind of door that can resist various shock waves or weight collision, general to be made using steel material.
For resistance train go together brought air pressure in tunnel, make internal unit intact, not by the harm of air pressure shock wave.
Tunnel protection door possesses superior explosion-proof performance, and antiknock reaches 0.11Mpa, while to have both fire protecting performance.It is commonly used in railway
Tunnel, such as transverse passage-way, repeater, cavern of transformer station.
One utility model patent of entitled high ferro tunnel protection door, Publication No. CN204691587U, including：Doorframe,
Circumferentially there is the outer installed part of multiple its front side, and the rear side of doorframe circumferentially has installed part in multiple；It is installed on by hinge
The door leaf of doorframe；It is installed on the coordinated type latch lock set between door leaf and doorframe；For detect door leaf whether locking in place
Detection device, it is connected to device of warning；Anti- plume between door leaf and doorframe；It is installed on the chain between door leaf and wall
Anti- to fly system, it includes being installed on the fixed pedestal of door leaf, is installed on the chain of fixed pedestal, and the chain other end is connected to cloth
Put the fixed pedestal on correspondence wall.The product prevent because high ferro in high-speed cruising when, the strong blast of generation and splashing
The rubble for rising, damages, various equipment of the protective door to tunnel cavern to the power equipment and communication equipment in Tunnel room
Play a protective role.When high ferro is stopped transport because of accident in tunnel, the protective door in fire escape plays passenger to tunnel
The function of outer emergency escape.
Utility model content
The utility model opens inconvenience mainly for the complex structure existing for prior art, the technology such as locking is unstable
A kind of problem, there is provided simple structure, opens convenient, the protective door linkage lock construction of locking stabilization.
To achieve the above object, the utility model employs following technical scheme：
Protective door linkage lock construction, including doorframe and the protective door on doorframe, set blocking lock knot on protective door
Structure, linkage lock construction includes handle, main gangbar, a pair of duplicate invoice levers and some latches, and a pair of duplicate invoice levers are parallel to each other to be set
Put, handle is fixed with main gangbar and riveted, activity rivets duplicate invoice lever, the other end of duplicate invoice lever respectively at the two ends of main gangbar
Fixed riveting latch.
Main gangbar and a pair of duplicate invoice levers constitute a quadrilateral frame structure, are fixed on mount structure by activity riveting
On protective door, while having deformation function, drive main gangbar to vertically move up and down by handle, thus change duplicate invoice lever with
Angle between main gangbar.
Preferably, handle growth strip, riveting, the afterbody fixation riveting of handle are fixed in the middle part of handle with main gangbar
Latch.
Handle can be fabricated to strip, can also be fabricated to it is discoid, strip handle compare discoid handle be easier behaviour
Make, in open and close protective door, exert a force more direct.
Preferably, handle is disposed in parallel relation to one another with duplicate invoice lever.
Handle keeps curving for synchronous and same angle with duplicate invoice lever on direction, increases the overall stabilization of blocking lock
Property.
To sum up, the features such as the utility model has simple structure, unlatching convenience, locking stabilization.
Brief description of the drawings
Fig. 1 is integrally-built a kind of view of the utility model embodiment；
Fig. 2 is the integrally-built another view of the utility model embodiment.
Description of reference numerals：1- handles, the main gangbar of 2-, 3- duplicate invoice levers, 4- latches.
Specific embodiment
For a further understanding of the utility model, the utility model preferred embodiment is retouched with reference to embodiment
State, but it is to be understood that these descriptions are simply to further illustrate feature and advantage of the present utility model, rather than to this practicality
The limitation of new claim.
A kind of protective door linkage lock construction is present embodiments provided, as shown in figure 1 and 2, including doorframe and installed in door
Protective door on frame, sets linkage lock construction on protective door, linkage lock construction includes handle 1, and main gangbar 2, a pair of duplicate invoices are moved
Bar 3 and latch 4, a pair of duplicate invoice levers 3 are disposed in parallel relation to one another, and handle 1 is fixed with main gangbar 2 and riveted, the two ends of main gangbar 2
Activity respectively rivets duplicate invoice lever 3, and the other end of duplicate invoice lever 3 fixes riveting latch 4.
The growth strip of handle 1, the middle part of handle 1 is fixed with main gangbar 2 and is riveted, and the afterbody of handle 1 fixes riveting latch
4。
Handle 1 is disposed in parallel relation to one another with duplicate invoice lever 3.
When using, upward pulling handle 1, handle 1 drives main gangbar 2 to move up, and main gangbar 2 drives duplicate invoice lever
3 are rotated, and duplicate invoice lever 3 drives latch 4 to curve downwards, and latch 4 departs from doorframe after curving downwards, and protective door is opened.Otherwise then will
Protective door is closed.
The explanation of above example is only intended to help and understands method of the present utility model and its core concept.Should refer to
Go out, for those skilled in the art, on the premise of the utility model principle is not departed from, can also be to this
Utility model carries out some improvement and modification, and these are improved and modification also falls into the utility model scope of the claims
It is interior.
