bayonet socket

5031,5041 that matches with described two spacer pins on two thumb wheels, bayonet socket matches with two

spacer pins

5013,5014, be used to drive the core wheel and rotate, also be respectively equipped with on two thumb wheels and can stir the

plectrum

5032,5042 that oblique tongue assembly slides; Two thumb wheels 503,504 and cam 502 are equipped with coaxial square hole, be used to transmit the rotation torsion of handle square rod, one outdoors handle square rod 10 be inserted in thumb wheel 503 square holes of a side outdoors, an interior handle square rod 9 is inserted in a thumb wheel 504 of an interior side, cam 502 square holes.

Lock core gear 6 is provided with the coaxial circular hole 601 that tapered end can be installed, lock core gear 6 both sides end faces be provided with can be hinged with lock housing 1 erection loop 602, be used for and lock housing 1 hinged installation, axially be provided with crank 603 along lock core gear 6 in the gear teeth outside, this crank 603 can slide by the side's of promotion tongue assembly 3, arrives just lockable side's tongue of certain angle by rotating crank 603.

Idler gear 7 is that the

concentric sector gear

11,12 of two different pitch radius is formed, and matches with described lock core gear 6 than long radius sector gear 11, and small radii sector gear 12 matches with described core wheel 501; The axle center of two

concentric sector gears

11,12 is provided with the axis of rotation 702 that can be hinged with lock housing 1; Axis of rotation can be hinged with lock housing 1, therefore, idler gear can be around axis of rotation 702 swings, do not overlap and the certain distance that staggers mutually with small radii sector gear 12 axial centre planes than long radius sector gear 11, such design helps the side's of installation tongue 3 more easily, lean on the end face of lock housing one side to be provided with balanced support pin 1101 so that idler gear 7 swings are more steady than long radius sector gear 11, fault rate is low, increases application life of the present utility model simultaneously.

The tongue assembly side of including, side tongue, the junction plate 8 that is connected with square tongue and can be promoted by described crank 603, junction plate 8 is provided with the breach 801 that matches with crank, when the certain angle that turns to the left side when crank withstands breach 801, side's tongue just can not be withdrawn in the lock housing, when the certain angle on the right of crank turns to withstands breach 801, side's tongue just can not stretch out outside the lock housing, thereby realize the locking of the other side's tongue, junction plate 8 is provided with gathering sill 802, one guide finger 15 passes gathering sill, on the fixedly connected lock housing 1 in its two ends, described idler gear 7 is provided with the deep-slotted chip breaker 701 that slides for guide finger 15.

Operating principle of the present utility model is as follows:

Side's tongue presses down the rotation handle inside and outside door under the situation of withdrawal, drive

plectrum

503 or 504 rotations by the handle square rod, thereby promotes the U type junction plate 13 on the oblique tongue, makes in the oblique tongue indentation lock housing, realizes unblanking; After unclamping handle, under the effect of spring 14, tiltedly tongue resets, and U type junction plate 13 promotes plectrum, and handle is resetted.

Side's tongue is under the situation of withdrawal, carry handle in door, drive plectrum 504 and cam 502 rotations by handle square rod 9, bayonet socket 5041 on the plectrum 504 promotes spacer pin 5014, core wheel 501 is rotated synchronously with plectrum 504, by core wheel 501 and breast wheel 7, the gear pair of breast wheel 7 and lock core gear 6, crank 603 promotion side's tongues on the lock core gear 6 slide to outside the lock housing, realization is locked a door, at this moment can lock lock core gear 6 by key turns, make the crank 603 locking side's tongues on the lock core gear 6, the side's of making tongue can not return back in the lock housing by rotating handle, in the time will in door, opening the door lock of having closed, pass through key rotation lock core, discharge lock core gear 6, press down handle then, handle square rod 9 drives plectrum 504 and cam 502 rotates, make shifting block 5021 on the cam 502 hold out against the upper surface of arc shaped groove 5012, core wheel 501 is rotated synchronously with plectrum 504, plectrum 504 promotes U type junction plate 13 contracts oblique gyrus lingulais, simultaneously, and by core wheel 501 and breast wheel 7, the gear pair of breast wheel 7 and lock core gear 6, crank 603 on the lock core gear 6 pushes back lock housing inside with square tongue 3, realizes opening the door.

Door lock side's tongue is under the situation of withdrawal, on outdoors, carry handle, drive plectrum 503 by handle square rod 10, bayonet socket 5031 on the plectrum 503 promotes spacer pin 5013, core wheel 501 is rotated synchronously with plectrum 503, by core wheel 501 and breast wheel 7, the gear pair of breast wheel 7 and lock core gear 6, crank 603 on the lock core gear 6 is pushed square tongue to the lock housing outside, realization is locked a door, and at this moment can make the crank 603 locking side's tongues on it by key lock lock core gear 6, the side's of making tongue can not return back in the lock housing with handle, because the handle square rod on limit only is connected with plectrum 503 outdoors, does not connect cam 502, therefore can not realize pressing down the function of the side's of opening tongue.

To sum up explanation, but this lock body puts pressure opening/closing side tongue on having realized in the door, the function that outdoors can only the side's of closing tongue can not open, only need exchange

handle square rod

9,10 inserted modes in use, make square rod 10 connect plectrum 503 and core wheel 502, square rod 9 connects plectrum 504, can realize the exchange of left and right opening door.
