Description

A kind of gear latch mechanism with anti-theft device

Technical field

This utility model is related to a kind of gear latch mechanism with anti-theft device.

Background technology

The door lock of conventional gears transmission, its assembling structure are all more complicated, cause the volume of lock body greatly, and opening and closing operations are taken Power, flexibility ratio is poor, theftproof performance is also weaker.

Utility model content

In order to overcome the complex structural designs of the gear drive of common door lock in prior art, the volume of lock body is caused Greatly, opening and closing operations are laborious, and flexibility ratio is poor, the problem that theftproof performance is weaker, and this utility model provides a kind of tooth with anti-theft device Wheel latch mechanism, the structure design of the gear latch mechanism with anti-theft device is compact, easy for operation flexibly, theftproof performance is strong, Reliability is high, long service life.

This utility model solves the technical scheme adopted by its technical problem：Draw including the dead bolt in lock body and lock body Plate, the side plate of lock body are provided with lock core mounting hole, and the lower section of dead bolt arm-tie arranges driving gear and driven gear in the lock body, main Moving gear is made up of upper and lower two-layer, and upper strata is gear ring, and for interlocking ring, on driving gear, axially arranged coupling lock core is installed for lower floor Inserting groove, the lock core of insertion drive driving gear to rotate by interlocking ring, the gear ring engagement driven gear of driving gear, passive tooth Two pin-and-holes of eccentric setting on wheel, arrange driving groove on dead bolt arm-tie, above dead bolt arm-tie arrange positioning seat, positioning seat upper band There are two eccentric pins, eccentric pin to be fixedly connected through driving groove with two pin-and-holes, eccentric pin forms transmission with driving groove Coordinate, sliding in the lock body arranges theft protection plate, and the end bosses of theft protection plate are engaged with lock core mounting hole, theft protection plate is by being hinged on Plectrum in lock body drives, and plectrum is pressed on torsion spring.

Driving groove includes a straight trough, the drive block that interval setting is protruded on the side side wall of straight trough, the eccentric pin of rotation Dead bolt arm-tie is driven to move forward and backward by drive block.

This utility model by above-mentioned specific design, with structure design is compact, easy for operation flexibly, theftproof performance By force, reliability height, the advantage of long service life.

Fig. 2 is assembling structure schematic diagram of the present utility model.

Fig. 3 is the location diagram of this utility model theft protection plate and lock core mounting hole in normal state.

Fig. 4 is the location diagram of this utility model theft protection plate and lock core mounting hole under anti-theft state.

Specific embodiment

As illustrated, this utility model includes that the dead bolt arm-tie 2 in lock body 1 and lock body 1, the side plate of lock body 1 are provided with lock Core installing hole 3, the lower section of dead bolt arm-tie 2 arranges driving gear 4 and driven gear 6 in the lock body 1, and driving gear 4 is by upper and lower two Layer is constituted, and upper strata is gear ring 4a, and lower floor is to interlock ring 4b, the inserting groove 4c that axially arranged coupling lock core is installed on driving gear 4, The lock core of insertion drives driving gear 4 to rotate by interlocking ring 4b, the gear ring 4a engagement driven gears 6 of driving gear 4, passive tooth Two pin-and-holes 5 of eccentric setting on wheel 6, arrange driving groove 7 on dead bolt arm-tie 2, arrange positioning seat 8, positioning above dead bolt arm-tie 2 Two eccentric pins 9 are carried on seat 8, eccentric pin 9 is fixedly connected through driving groove 7 with two pin-and-holes 5, eccentric pin 9 and biography Dynamic groove 7 forms transmission and coordinates, and slides and arrange theft protection plate 10 in lock body 1, end bosses 13 and the lock core mounting hole 3 of theft protection plate 10 It is engaged, theft protection plate 10 is driven by the plectrum 11 being hinged in lock body 1, and plectrum 11 is pressed on torsion spring 12.Driving groove 7 is included always The drive block 7b that interval setting is protruded on the side side wall of groove 7a, straight trough 7a, the eccentric pin 9 of rotation are driven by drive block 7b Dead bolt arm-tie 2 is moved forward and backward.Under in working order, the shifting block on lock core drives driving gear 4 to rotate by interlocking ring 4b, actively Gear 4 drives driven gear 6 to rotate simultaneously, is connected on driven gear 6 two eccentric pins 9 with setting on dead bolt arm-tie 2 Drive block 7b be engaged, drive dead bolt arm-tie 2 to advance or retreat, complete to unlock or locking.Under anti-theft state, if lock core It is damaged violently or takes away, then plectrum 11 promotes theft protection plate 10 to slide under the pressure of torsion spring 12, the end bosses of theft protection plate 10 13 one end for blocking at once lock core mounting hole 3, prevent from inserting standby lock core opening door lock.Embodiment described above is only right A kind of preferred implementation of the gear latch mechanism with anti-theft device of this utility model is described, not the structure to utility model Think and scope is defined, on the premise of without departing from this utility model scheme, those skilled in the art are to of the present utility model Various external form modifications and improvement that technical scheme is made, all should fall into a kind of gear latch mechanism with anti-theft device of this utility model Protection domain.
