Description
Technical field
The present invention relates to a kind of gear drives of door lock.
Background technology
The door lock of conventional gears transmission, assembling structure is all more complicated, causes the volume of lock body big, opening and closing operations are taken
Power, flexibility ratio are poor.
Invention content
In order to overcome the complex structural designs of the gear drive of common door lock in the prior art, the volume of lock body is caused
Greatly, opening and closing operations are laborious, and the problem of flexibility ratio difference, the present invention provides a kind of gear drive of door lock, the gear of the door lock
The structure design of transmission mechanism is compact, it is easy for operation flexibly, reliability is high, service life is long.
The technical solution adopted by the present invention to solve the technical problems is：Including the lock tongue pulling plate in lock body and lock body,
Gear housing is fixed in the bottom of lock body, and driving gear, two intermediate gears and driven gear, driving gear is arranged in gear housing
It is made of upper layer and lower layer, upper layer is interlock ring, and lower layer is gear ring, and the grafting of matching lock core installation is axially arranged on driving gear
The lock core of slot, insertion drives driving gear to rotate by interlock ring, gear ring two intermediate gears of engagement of driving gear, in two
Between gear engage driven gear, the top axial of driven gear fixes two eccentric pins, and eccentric pin is set on lock tongue pulling plate
The driving groove set matches.
It is fixedly connected with gear box cover in the upper end of gear housing, gear box cover is equipped with elongated slot, and eccentric pin is pierced by elongated slot
It is matched outside with the driving groove being arranged on lock tongue pulling plate.
Driving groove includes a straight trough, and the drive block of setting protrusion, the eccentric pin of rotation are spaced on the side side wall of straight trough
Lock tongue pulling plate is driven to be moved forward and backward by drive block.
By above-mentioned specific design, the gear in lock body is run the present invention in gear-box, substantially increases the steady of operation
It is qualitative, have the advantages that it is easy for operation flexibly, reliability it is high, with long service life.
Description of the drawings
Illustrate the detailed content of the present invention below in conjunction with drawings and examples.
Fig. 1 is the decomposition texture schematic diagram of the present invention（Omit gear box cover）.
Fig. 2 is the assembling structure schematic diagram of the present invention.
Fig. 3 is middle gear drive mechanism schematic diagram of the present invention.
Specific implementation mode
As shown, the present invention includes the lock tongue pulling plate 2 in lock body 1 and lock body 1, gear-box is fixed in the bottom of lock body 1
Body 3, interior setting 4, two intermediate gears 5 of driving gear of gear housing 3 and driven gear 6, driving gear 4 is by upper layer and lower layer structure
At upper layer is interlock ring 4a, and lower layer is gear ring 4b, and the inserting groove 4c of matching lock core installation is axially arranged on driving gear 4, is inserted into
Lock core drive driving gear 4 to rotate by interlock ring 4a, the gear ring 4b of driving gear 4 engages two intermediate gears 5, in two
Between gear 5 engage driven gear 6, the top axial of driven gear 6 fixes two eccentric pins 7, eccentric pin 7 and lock tongue pulling plate
The driving groove 8 being arranged on 2 matches.It is fixedly connected with gear box cover 9 in the upper end of gear housing 3, gear box cover 9 is equipped with elongated slot
10, eccentric pin 7 is pierced by outside elongated slot 10 and is matched with the driving groove 8 being arranged on lock tongue pulling plate 2.Driving groove 8 includes a straight trough 8a,
The drive block 8b of interval setting protrusion, the eccentric pin 7 of rotation drive lock tongue by drive block 8b on the side side wall of straight trough 8a
Pulling plate 2 is moved forward and backward.In the operating condition, the shifting block on lock core drives driving gear 4 to rotate by interlock ring 4a, driving gear
4 drive driven gear 6 to rotate simultaneously by two intermediate gears 5, two on driven gear 6 piece eccentric pin 7 and lock tongue pulling plate 2
The drive block 8b of upper setting is matched, and lock tongue pulling plate 2 is driven to move forward or back, and is completed to unlock or is latched.Above-described implementation
Example is only that a kind of preferred embodiment of the gear drive of door lock of the present invention is described, not to the design of invention
It is defined with range, under the premise of not departing from the present invention program, those skilled in the art make technical scheme of the present invention
The various external form variations and modifications gone out should all fall into a kind of protection domain of the gear drive of door lock of the present invention.
