Description
Technical field
The utility model relates to a kind of door lock, is specifically related to EMU toilet door combination lock.
Background technology
The handling characteristics of train closet door is, passenger can know in lavatory have nobody at a distance, and lavatory should be in locking states during unmanned use, when passenger enters in lavatory, opposite house is also needed to carry out the locking cannot opened outside in inside for preventing outside passenger from accidentally entering.Existing lockset is single latch, belongs to closing type lockset, and in the unlatching of lockset or the process of closedown, easy appearance collides and friction, and it is unstable, dangerous that long collision and friction make lockset use.
Along with train continuous speed-raising to 200 kilometer, 300 kilometers even higher, EMU upholstery requires attractive in appearance, light and sound construction therefore to propose new requirement to the design of lavatory door lock.
Summary of the invention
In order to overcome the above problems, the purpose of this utility model is to provide novel EMU toilet door combination lock.
EMU toilet door combination lock described in the utility model, comprises lock body and the handle box set within it, long locking bar, built-in lock, short locking bar; Wherein lock body is flat high rectangular housing, and its inner bottom part installs the handle box can slided along lock body, and long locking bar is fixed on handle box top and is through to lock body top; Built-in lock is fixed on middle part in lock body; Be respectively equipped with rotor A and rotor B in handle box and built-in lock, the bar shaped plectrum that rotor A and rotor B include cylinder rotating shaft and be fixedly connected with rotating shaft, described rotating shaft is arranged in the round tube hole on lock body and also coordinates with it, and spindle central arranges lock core hole; The plectrum both sides of rotor A are respectively arranged with alignment pin, and it is inner and outside that alignment pin lays respectively at handle box; Be positioned at rotor B side in built-in lock and be provided with slideway, slide plate is placed in slideway and also coordinates with it, and the plectrum of rotor B is placed in the track groove on slide plate, and short locking bar is connected with slide plate; Two handles are placed in the lock core hole of rotor A by its up knob core and are arranged on lock body both sides; Built-in lock switch comprises locking knob, has unmanned display board and knob core, wherein locking knob and have unmanned display board to be arranged on knob core two ends, and knob core is placed in the lock core hole of rotor B.
During work, first the handle on lock body is rotated, handle moves rotor A by the handle core ribbon on it and rotates, plectrum in rotor A drives handle box to slide in lock body, thus drive the long locking bar be fixed in handle box to move up and down, complete unlatching and the locking of toilet door thus, the alignment pin of rotor A plectrum both sides plays the effect limiting long locking bar stroke; After passenger enters lavatory, rotate the locking knob inside toilet door, rotor B will rotate thereupon, thus drive slide plate to slide in slideway, the short locking bar be connected with slide plate also will move up and down thereupon in lock body, complete the locking of second lock, to corresponding actions be there is in now corresponding with locking knob outside the toilet door unmanned display board that has, the passenger of outside can learn that there is people the inside, even if do not note observing, also cannot open toilet door from the handle outside toilet door and first lock, bring safety to thus the passenger of the inside.
EMU toilet door combination lock described in the utility model, structure is simple, frivolous, firm, dual fail-safe, combine closely with EMU toilet door exquisiteness, the collisionless when lockset opens and closes, wearing and tearing are few, even if operationally speed up to 200 kilometers even 300 kilometers when, still the state of silent, structural safety can be kept, and all parts are demountable structure, long service life, convenience easy to maintenance, meets the service requirement of high speed motor car completely, provides guarantee also to the safety of passenger.
In order to reach better effect, the utility model can also in the following ways:
1, between rotor B and nearer built-in lock sidewall, be provided with torsion spring, the torque arm at torsion spring two ends is pressed in the corresponding draw-in groove of rotor B and on the sidewall of lock body respectively.Under the effect of torsion spring two ends elastic force, rotor B can obtain fastening in rotary course, is not subjected to displacement, thus it is smooth and easy that the slip of slide plate is stablized more.
2, described long locking bar and short locking bar comprise some sections respectively, and arrange spring between adjacent two sections.Its advantage is, when encountering hard object after long locking bar or short locking bar stretch out, can continue to rotate, make dead bolt have retract stroke, dead bolt is normally stretched out, realize closing the door, and directly can not damage lockset.
3, the top in lock body arranges locating support, and the through hole on it coordinates with long locking bar and short locking bar respectively.Thus limit the lateral displacement of long locking bar and short locking bar, make it move up and down more steady.
4, described EMU lavatory combined door-lock also comprises sensor and display, and described sensor is arranged on short locking bar corresponding position, lock body top.When short locking bar and second lock locking, indicate that passenger enters lavatory, now display passed to by sensor, and display shows people, thus makes passenger at a distance grasp lavatory using state very easily.
5, described EMU toilet door combination lock also comprises fore shaft, coordinates with long locking bar and short locking bar.Fore shaft is fixed on above lock body, enters in the fore shaft matched, thus complete locking when long locking bar and short locking bar extend.The setting of fore shaft reduces the friction of locking bar, reduces fricative noise, adds the application life of lockset.
