Abstract
The utility model relates to a door lock which comprises a housing, a lock core, a lock bolt, a supporting plate, a movable contact and an inner handle. The utility model is characterized in that the utility model also comprises a crank drive plate transmission mechanism and a thorn groove and pawl type self-locking mechanism and adopts a torsional spring to provide automatic locking power for the lock bolt; the utility model is additionally provided with a locking plate and a locking pressure spring. The utility model has the advantages of portable slide of the lock bolt, good self-locking function, accurate self locking, convenient unlocking, labor saving, reliable automatic locking power providing and reliable internal locking performance.
Description
The utility model relates to a kind of door lock.
When being used for door lock by outer tapered end or inner lock head or interior external-open of interior handle realization door lock or locking, theftproof lock or Automatic anti-theft lock that prior art is produced, its transmission mechanism realize inside and outside the locking.Transmission mechanism all adopts crank-link mechanism or pinion and rack.Because this transmission mechanism one is to float to be fixed in the lock body, when locking or automatically locking, be prone to resistance and roll, make the disabler that automatically locks; The 2nd, the power of locking is big, and the spring of locking is prone to fracture and makes the inefficacy of locking.
The purpose of this utility model provides the good Automatic anti-theft lock of a kind of function that automatically locks.
To achieve these goals, the technical solution adopted in the utility model: a kind of Automatic anti-theft lock comprises housing, is fixedly connected with dead bolt supporting plate, lock core, armature contact, the interior handle of dead bolt; Crank dial transmission mechanism: inside and outside crank is fixedlyed connected with rotating shaft, lock core in the interior handle respectively, and dial is provided with inside and outside crank shifting block, sour jujube groove, torsion spring, dial by the axle two ends respectively with interior handle in rotating shaft, lock core be slidingly connected; Be provided with the seat axle on housing, be equipped with torsion spring on it, two fixing feet of torsion spring are supported on respectively on housing, the dead bolt supporting plate; Be fixedly connected with the self-locking plate axle on the dead bolt supporting plate with fixedly self-locking plate, torsion spring, self-locking plate is provided with ratchet.
Below in conjunction with drawings and Examples the utility model is described in further detail.
Fig. 1 removes the structural representation of back shroud for the utility model embodiment.
Fig. 2 looks partial sectional view for the right side of Fig. 1.
As shown in Figure 1, 2, the utility model Automatic anti-theft lock comprises housing 1, is fixedly connected with dead bolt supporting plate 7, lock core 19, armature contact, the interior handle 21 of dead bolt; Crank dial transmission mechanism: inside crank 23, outside crank 20 are connected with rotating shaft 22, lock core 19 keys in the interior handle 21 respectively, and dial 12 is provided with inside crank shifting block 25, outside crank shifting block 26, be used for realizing opening door lock and inside and outside unblank fixed; Dial 12 is provided with torsion spring 13, when being used for locking a door automatically dead bolt is automatically locked; Dial 12 by the axle two ends respectively with interior handle 21 in rotating shaft 22, lock core 19 be slidingly connected; Housing 1 is provided with seat axle 9, is equipped with torsion spring 8 on it, is used for automatically locking when dead bolt is locked, and two fixing feet of torsion spring 8 are supported on respectively on housing 1, the dead bolt supporting plate 7; Riveted joint has self-locking plate axle 18 on the dead bolt supporting plate 7, is used for fixing self-locking plate 5, torsion spring 6, and self-locking plate 5 is provided with ratchet 10, with the sour jujube groove 11 common lock dials 12 on the dial 12; Be provided with thimble 3, stage clip 4 in the hollow armature contact 2, be used to automatically lock; Dead bolt supporting plate 7 is provided with keyway 16, places the key axle 17 of keyway 16 to be fixedly connected on the housing 1, is used for the dead bolt guiding, and the bent axle 14 on the dial 12 places the triangle slotted eye 15 on the dead bolt supporting plate 7, is used for realizing unblanking and supporting role.
During use: 1. door lock locking: under the external force effect of closing the door, the reaction compressive force that thimble 3 is subjected to doorframe is pressed in the hollow armature contact 2, promote self-locking plate 5, to ratchet 10 disengaging sour jujube grooves 11, thereby locking is disengaged, door lock reaches when closing position, and dead bolt ejects under torsion spring 8,13 effects and enters doorframe latch plate hole and realize that door lock automatically locks.Thimble 3 ejects homing under the elastic force effect of stage clip 4, self-locking plate 5 is also replied state to be locked under torsion spring 6 effects.
2. turn the key in the lock: key is inserted lock core 19 turn clockwise, at this moment lock core 19 drives outside crank 20 rotations, because the effect of inside and outside crank shifting block 25,26, outside crank 20 drives dial 12 and rotates, making dial 12 drive dead bolt by bent axle 14 through triangle slotted eye 15 slides, makes the dead bolt retraction; A few can unblank screw key, when reaching lockset position of coupler, and lockplate 5 lock dials 12, opening the door is held.
3. interior handle opens the door: handle 21 in being rotated counterclockwise with hand, making rotating shaft 22 drive inside crank 23 rotates, the inside crank shifting block 26 of arm 24 on dial 12 of dialling of inside crank 23 drives dial 12 rotations, thereby make the triangle slotted eye 15 on the bent axle 14 effect dead bolt supporting plates 7 drive 7 slips of dead bolt supporting plate, make the dead bolt withdrawal, in the rotation handle a few promptly realize unblanking after putting in place, self-locking plate 5 lock dials 12 unblank to be held simultaneously.
Good effect of the present utility model is
1. adopt crank driver plate transmission mechanism, driver plate does not have the dead point in rotation process, rotates without hindrance Roll, it is light that dead bolt is slided, and automatic locking function is good.
2. adopt sour jujube groove and pawl type self-locking mechanism, so that self-locking is accurate, release is convenient, release Power is little.
3. adopt torsion spring that the power that automatically locks of main dead bolt is provided, it is reliable that the power of locking provides.
4. set up lockplate, locking stage clip, made the outer dependable performance of internal lock.
