As shown in fig. 1-10, a cabin door lock includes a lock cylinder 501, a clutch mechanism, a balance mechanism, a torsion sleeve 301, a rotation sleeve 701, and a lock block 111, where one end of the lock cylinder 501 is provided with a rotation block 503 and the other end is provided with a lock hole 506, a key 1 is inserted into the lock hole 506, the clutch mechanism is composed of a torsion disc 601 and a first spring 604, one end of the torsion disc 601 is provided with a transverse trough 602, and the other end is provided with a torsion block 603, the balance mechanism is composed of a balance block 801 and a second spring 802, the balance block 801 is provided with a first projection 803, a second projection 805, a wedge 806, and a positioning shaft 804, two ends of the second spring 802 are respectively positioned on the positioning shaft 804, the wedge 806 is matched with the torsion block 603, the wedge 806 can move up and down along with the rotation of the torsion block 603, the torsion sleeve 301 is provided with a first through slot 302 and a sliding slot 303, and the rotation, The lock core 501 comprises two keys 1, one is shorter and can only contact with the lock core 502, the other is longer and can contact with the chip replacement 507, the twist sleeve 301 is matched with the rotation sleeve 701 through a third spring 9, the rotation sleeve 701 is matched with the lock block 111 through a fourth spring 10, the lock core 501 is installed in the lock core sleeve 14, the lock core 501 is further provided with a fixture block 504, the lock core sleeve 14 is provided with a groove 505, the fixture block 504 is matched with the groove 505, the twist disc 601 is further provided with a first spring 604, the other end of the first spring 604 is fixed at the bottom of the positioning hole 305 in the twist sleeve 301, still be equipped with blind hole 304 on turning round cover 301, turn round cover 301 through installing pin in blind hole 304 is followed third through slot 703 slides, it is equipped with locating hole 305 to turn round cover 301 one end, third spring 9 one end is installed in locating hole 305, locking piece 111 one end is equipped with position sleeve 113, fourth spring 10 pot head is in on the position sleeve 113, the locking piece 111 other end passes through screw 12 and fixes spring bolt 4 on locking piece 111, still install cylindric lock 112 on the locking piece 111, cylindric lock 112 can follow the cam slot 704 slides, the cover has position sleeve 113 on turning round cover 701, be equipped with the location fender on the position sleeve 113, the location fender is located the cam slot 704 peak.

The specific working process is as follows: the process of unblanking is first step, after the key of unblanking inserts the lockhole, the lock chip piece is arranged neatly, the fixed of lock core and lock sleeve is relieved, 90 in-process of anticlockwise rotation key, the commentaries on classics piece on the lock core drives through the cross slot and turns round the dish rotation, and then turn round the piece on the dish and drive the voussoir compression cover on the balancing piece and fix epaxial second spring, the second lug on the balancing piece slides along the spout of turning round the cover, when first lug descends to the logical inslot of second, turn round the fixed of being relieved between cover and the commentaries on classics cover, will turn round the cover when the third spring that is in compression state resets and follow the third through slot roll-off on the commenta.

And in the second unlocking step, in the process of rotating the knob sleeve by 180 degrees anticlockwise, the knob sleeve rotates along with the knob sleeve under the action of the pin, the knob sleeve rotates to drive the cylindrical pin on the locking block to rotate through the cam groove and extend outwards, the cabin door is opened, and the fourth spring is reset at the moment.

And (3) locking: clockwise rotation turns round 180 in-process of cover, it is rotatory along with turning round the cover together to turn round the cover under the effect of pin to turn round the cover, it is rotatory when will driving the cylindric lock on the locking piece through the cam slot to turn round the cover, the fourth spring is compressed, only need to turn round the cover with the hand and compress inwards this moment, the balancing piece gets back to behind the second slotted position, it will turn round the cover and fix once more to reset under the effect of second spring, the voussoir resets simultaneously and drives and turns round the dish and reset and then drive the lock core and reset, the lock is also followed lock core automatic re-setting, it can not directly extract to need to.

If the unlocking key is lost, the lock core is only required to be replaced at the moment, and the lock is not required to be bought again at high cost. Demolish the lock core, insert and trade the core key, it will trade chip jack-up to trade the core key this moment, 4 first springs bounce turns round the dish, thereby turn round the dish and break away from the balancing piece, the lock core is turned round the dish and is bounced, anticlockwise rotation lock core 90, the lug of lock core is just in time and lock sleeve recess coincidence this moment, and need not dismantle follow-up structure, directly take out the lock core can, then insert new lock core, clockwise rotation 90, the rotor on the lock core and turn round the coincidence of horizontal trench position on the dish this moment, press the lock core gently, it can accomplish and trade the core to extract the key.

Because the twist sleeve needs to be often bounced to do rotation, the lock cylinder sleeve and the twist sleeve of the traditional lock are connected by adopting glue, in order to separate the lock cylinder sleeve from the twist sleeve, the lock cylinder sleeve is connected by adopting an elastic pin, so that the lock cylinder sleeve is more durable, and meanwhile, compared with a traditional single balance block structure, the balance mechanism adopts a double balance block structure, so that the use is more stable.
