Description
Technical field
The utility model is related to a kind of plant equipment, especially a kind of protection door lock alarm structure.
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 is mainly for the complex structure existing for prior art, and security is poor, and locking signal is indefinite
Etc. technical problem, there is provided a kind of simple structure, preferably, locking signal clearly protects door lock alarm structure to security.
To achieve the above object, the utility model employs following technical scheme：
Protection door lock alarm structure, including doorframe and the protective door on doorframe, set door lock sensing in doorframe
Device, the bottom of door lock inductor is provided with telescopic push rod, and door latch structure is provided with protective door, and door latch structure includes linkage
Structure and the latch for being connected to linkage structure end, set latch groove on doorframe, latch, latch groove and push rod are located at same level
Highly.
After latch is rotated into latch groove by the control of link gear, push rod is touched, by the upward jack-up of push rod, push rod sets out
Whether door lock inductor produces signal, confirms the complete closing of protective door.
Preferably, linkage structure includes handle, main gangbar and duplicate invoice lever, duplicate invoice lever connecting bolt.
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, latch fixes riveting with duplicate invoice lever.
Preferably, handle is fixed with main gangbar riveting, main gangbar is riveted with the activity of duplicate invoice lever.
Handle drives main gangbar and duplicate invoice lever, and the switch protective door power of applying is passed to slotting by the lock construction that links
Pin.
Preferably, door lock inductor connection alarm lamp and power supply.
Door lock inductor is converted into alarm lamp indication signal after receiving the signal that push rod is touched.
To sum up, the utility model has a simple structure, security preferably, the features such as locking signal is clear and definite.
Brief description of the drawings

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 protection door lock alarm structure is present embodiments provided, as shown in figure 1 and 2, including doorframe and is arranged on
Door lock inductor 2 is set in the protective door on doorframe, doorframe 1, and the bottom of door lock inductor 2 is provided with telescopic push rod 3, is prevented
Door latch structure is provided with shield door, door latch structure includes linkage structure and is connected to the latch 4 of linkage structure end, on doorframe 1
Latch groove is set, and latch 4, latch groove and push rod 3 are located at same level highly.
Linkage structure includes handle 5, main gangbar 6 and duplicate invoice lever 7, the connecting bolt 4 of duplicate invoice lever 7；Latch 4 and duplicate invoice
Lever 7 fixes riveting；Handle 5 is fixed with main gangbar 6 and riveted, and main gangbar 6 is riveted with the activity of duplicate invoice lever 7.Handle 5 is grown up
Strip, the middle part of handle 5 is fixed with main gangbar 6 and is riveted.The afterbody of handle 5 can also increase fixed riveting latch 4.Handle 5
Can be disposed in parallel relation to one another with duplicate invoice lever 7.
Door lock inductor 2 connects alarm lamp 8 and power supply 9.
When using, downward pulling handle 5, handle 5 drives main gangbar 6 to move down, and main gangbar 6 drives duplicate invoice lever
7 rotate, and duplicate invoice lever 7 drives latch 4 to curve upwards, and latch 4 enters in latch groove after curving upwards and touched with push rod 3,
Push rod 3 is compressed in lasting upward motion, behind the predetermined position for reaching, push rod 3 causes that door lock inductor 2 produces sensing letter
Number, alarm lamp 8 sends protective door shutdown signal after receiving induced signal, it is ensured that protective door is closed in place.
Otherwise then protective door is opened.
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.
