Shown in Fig. 1～2, a kind of mortise door lock with gear transmission structure, include lock housing 1, oblique tongue assembly 2, square tongue assembly 3 are installed in the lock housing 1 and can drive oblique tongue assembly 2 or/and square tongue assembly 3 stretches out the gear drive 4 in the outer or withdrawal lock housing 1 of lock housing 1, also include the lock core 6 that is used to the side's of locking tongue assembly 3, gear drive 4 comprises the rack-plate 8 on handle gear assembly 5, the side's of the being anchored on tongue and is installed on the idler gear 7 that is used for transferring power between the two.

As Fig. 3～shown in Figure 6, handle gear assembly 5 comprises core wheel 501, the excircle of core wheel is distributed with some driving cogs, which is provided with coaxial through-hole 5011, also be provided with the deep-slotted chip breaker 5012 that connects with through hole 5011, a cam 502 is installed in the through hole 5011, cam 502 can rotate in through hole 5011, its excircle is provided with shifting block 5021, and this shifting block can rotate in deep-slotted chip breaker 5012; Core is taken

turns spacer pin

5013,5014 is installed on the 501 both sides end faces, core is taken turns 501 both sides end faces and is separately installed with thumb wheel 503,504, two thumb wheels are hinged and can rotation in the core wheel by boss and cam 502, be respectively equipped with

bayonet socket

5031,5041 on two thumb wheels, bayonet socket matches with two

spacer pins

5013,5014, be used to drive the core wheel and rotate, also be provided with on the thumb wheel and can stir the

plectrum

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

Lock core 6 is provided with the coaxial circular hole 601 that tapered end can be installed, and lock core 6 both sides end faces are provided with erection loop 602, is used for and lock housing 1 hinged installation, axially is provided with crank 603 in the gear teeth outside along lock core gear 6, and crank forwards certain angle lockable side tongue to by rotating.

Idler gear 7 is made up of the

concentric sector gear

11,12 of two different pitch radius, matches with above-mentioned rack-plate 8 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 axis of rotation 701, and axis of rotation can be hinged with lock housing 1, and therefore, idler gear can be around axis of rotation 701 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, the purpose of She Zhiing is for convenience of mounting teeth batten 8 like this, than long radius sector gear 11 by being provided with balanced support pin 1101 on the end face of lock housing one side so that idler gear 7 swings are more steady, under the fault rate, increase application life of the present utility model simultaneously.

The tongue assembly side of including, side tongue 3, on above-mentioned rack-plate 8 side's of being riveted on tongues, rack-plate 8 is provided with the breach 801 that matches with crank 603, when crank turns to left side certain angle when withstanding breach 801, side's tongue just can not be withdrawn in the lock housing, when certain angle withstood breach 801 on the right of crank turned to, square tongue just can not stretch out outside the lock housing, thereby realized the locking of the other side's tongue; Have on the rack-plate 8 with idler gear 7 on the tooth bar that matches than long radius sector gear 11, gear pair by core wheel 501, idler gear 7 and rack-plate 8, make the rectilinear motion of the rotation side of the being transformed into tongue of handle, rack-plate 8 is provided with gathering sill 802, one guide finger 15 passes gathering sill, its two ends are fixedly connected on the lock housing 1, and gathering sill 802 slides on guide finger 15, thereby guide finger 15 defines the length that the range of movement side of the qualification tongue 3 of rack-plate 8 stretches out lock housing.

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, the torsion by the handle square rod drives

plectrum

503 or 504 and rotates, thereby promotes the 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 junction plate 13 promotes plectrum, and handle is resetted.

Door lock side's tongue is under the situation of withdrawal, carry the rotation handle in door, drive plectrum 503 and cam 502 rotations by handle square rod 9, 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 rack-plate 8, side's tongue is pushed to the lock housing outside, realizes locking a door, and at this moment can pass through key rotation lock core 6, make the crank 603 locking side's tongues on it, the side's of order tongue can not return back in the lock housing, when opening the door lock of having closed in door, by key rotation lock core 6, make the crank 603 release side's tongues on it, press down the rotation handle then, handle square rod 9 drives plectrums 503 and cam 502 rotates, and makes shifting block 5021 on the cam 502 hold out against the upper surface of arc shaped groove, core wheel 501 is rotated synchronously with plectrum 503, plectrum 503 promotes 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 rack-plate 8, side's tongue is pulled lock housing inside, realizes opening the door.

Door lock side's tongue is under the situation of withdrawal, on outdoors, carry the rotation handle, drive plectrum 504 by handle square rod 10, bayonet socket 5031 on the plectrum 504 promotes spacer pin 5013, 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 rack-plate 8, side's tongue is pushed to the lock housing outside, realization is locked a door, and at this moment can pass through key rotation lock core 6, makes the crank 603 locking side's tongues on it, the side's of making tongue can not return back in the lock housing, because the handle square rod on limit only is connected with plectrum 504 outdoors, does not connect cam 502, therefore can not open door lock side's tongue by pressing down handle.

To sum up explanation, press handle opening/closing side tongue but put on this lock body has been realized in the door, and outdoors handle can only close can not the side's of opening tongue function, only need exchange

handle square rod

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