Background technology
Existing at present electronic two door locks of opening electric door mostly are arranged in the mechanism, realize by linking to each other with screw axis the institute of door system is closed, though form that this kind closes is also fairly simple, can only satisfy the requirement of low speed car.Develop rapidly along with socioeconomic, the inter-city passenger rail passenger traffic can not be satisfied the demand of society, inter-city passenger rail passenger traffic public transportization, rapid requirement, pleasant property, reliability and the safety that improve stopping sliding door.The volume of the flow of passengers of intercity passenger traffic is bigger, the corresponding increase of passenger getting on/off flow, therefore to increase the quantity of every joint car door and the aperture of increase door, and along with the high speed of inter-city train, sealing performance, sound insulation value, heat-proof quality, safety, reliability to door system are had higher requirement, and have increased the difficulty of door system technology.
Summary of the invention
The purpose of this utility model is a kind of active multistage locking device that is used for the track train door system of requirement proposition according to high speed inter-city train opposite house locking system security performance, and it can effectively improve the sealing performance and the security performance of door system.
Technical solution of the present utility model, its structure is that an end of power transmission shaft links to each other with little hanger on the driving mechanism by flap, auxilliary locking device is by being bolted on the car body, tumbler gear on the auxilliary locking device links to each other with power transmission shaft by adjusting gear, auxilliary lock is adjusted gear and is joined by tumbler gear and auxilliary lock latch hook, main lock cartridge is put by being bolted on the car body, the tumbler gear that main lock cartridge is put links to each other with power transmission shaft by adjusting gear, main lock is adjusted gear and is joined by tumbler gear and main lock latch hook, main lock latch hook joins by the following end-toothed disc of connecting axle with main lock slipping toothed electromagnetic clutch, and wire rope is connected with the last end-toothed disc of slipping toothed electromagnetic clutch in the main lock.
Advantage of the present utility model: adopt multistage locking device, simultaneously locking car door and mechanism have increased the safety and the reliability of door system.

Accompanying drawing 5 is main lock schematic cross-sections.
Among the figure 1 is flap, the 2nd, and upper bracket, the 3rd, auxilliary locking device, the 4th, power transmission shaft, the 5th, lower carriage, the 6th, main lock cartridge is put, the 7th, auxilliary lock latch hook, the 8th, auxilliary lock tumbler gear, the 9th, auxilliary lock is adjusted gear, the 10th, main lock latch hook, the 11st, main lock tumbler gear, the 12nd, main lock is adjusted gear, the 13rd, main lock is end-toothed disc down, the 14th, the last end-toothed disc of slipping toothed electromagnetic clutch in the main lock, the 15th, slipping toothed electromagnetic clutch, the 16th, wire rope.
The specific embodiment
Contrast accompanying drawing 1,2,3,4,5, its structure is that an end of power transmission shaft 4 links to each other with little hanger on the driving mechanism by flap 1, and join with slipping toothed electromagnetic clutch 15, main lock cartridge is put 6 and is fixed on the car body by lower carriage, the tumbler gear 11 that main lock cartridge is put on 6 links to each other with power transmission shaft 4 by adjusting gear 12, main lock is adjusted gear 12 and is joined by tumbler gear 11 and main lock latch hook 10, main lock latch hook 10 is locked down with the master, and end-toothed disc 13 joins, the main end-toothed disc 14 of locking joins with slipping toothed electromagnetic clutch 15, and wire rope 16 is connected with the last end-toothed disc 14 of slipping toothed electromagnetic clutch.
One end of power transmission shaft 4 links to each other with little hanger on the driving mechanism by flap 1, and also with the both sides that are installed in car body 1 after the auxilliary locking device 3 of car door middle and upper part is connected, the corresponding setting of latch hook on the stopper on the door leaf 5 and the auxilliary locking device 3.
Described auxilliary locking device 3 is fixed on the car body by upper bracket, and the tumbler gear on the auxilliary locking device 3 links to each other with power transmission shaft 4 by adjusting gear, and auxilliary lock is adjusted gear and joined by tumbler gear and auxilliary lock latch hook 7,
During work, the little hanger on the driving mechanism is converted into the rotation of power transmission shaft 4 along the rectilinear motion of short guiding column by flap 1, and the rotation of power transmission shaft 4 drives auxilliary locking device 3 and main lock cartridge and puts 6 and rotate and realize initiatively release and locking functions.
When opening the door, slipping toothed electromagnetic clutch 15 energisings make the last end-toothed disc 14 of slipping toothed electromagnetic clutch and following end-toothed disc 13 break away from engagement, main lock latch hook 10 backward rotation under the drive of power transmission shaft 4, auxilliary simultaneously lock latch hook 7 is backward rotation under power transmission shaft 4 drives also, realizes release, and door is opened.
At closing time, slipping toothed electromagnetic clutch 15 outages, back-moving spring in the slipping toothed electromagnetic clutch resets, main lock end-toothed disc 14 and main lock down end-toothed disc 13 realizes again meshing, this moment, the auxilliary lock adjustment of the rotation drive gear 9 of power transmission shaft 4 rotated, driving auxilliary lock latch hook by auxilliary lock tumbler gear 8 simultaneously rotates and realizes that auxilliary lock compresses the door-plate function, main simultaneously lock is adjusted gear 12, and also next plays rotation in the drive of power transmission shaft 4, driving main lock latch hook by main lock tumbler gear 11 rotates, when door is closed fully, auxilliary lock latch hook 7 and main lock latch hook 10 hook the stopper on the door-plate, the locking function that the last end-toothed disc 14 by slipping toothed electromagnetic clutch and the one way engagement of following end-toothed disc 13 realize guarantees that the reliability of door system and sealing performance meet the demands.
