The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

As Fig. 1, shown in Figure 2, theftproof lock, comprise lock box, main tongue mechanism, oblique tongue mechanism, inserting-core lock, oblique guiding groove 62 is with in the centre, the upper sliding valve 6 of transverse guidance groove 61, the stretching device up and down that the downslide bolt 7 of same structure constitutes, main tongue mechanism is linked to each other with supporting plate 32 by master latch 31, by tapered end one side an opening groove 321 is set at supporting plate 32, the centre has guiding groove 322, by post 95 guiding that are fixed on the base plate, opposite side has locating slot 323, one main tongue location-plate 33 is arranged under the supporting plate, location-plate 33 1 ends link to each other with fixed leg 12 on being fixed on base plate by spring 34, and be enclosed within on the post 14 by located lateral groove 331, the other end 332 embeds in the transverse groove 511 of guide plate 51 downwards, locating slot 323 on projection (covering among the figure) the embedding supporting plate is arranged at the bottom, upper sliding valve 6, downslide bolt 7 is respectively on supporting plate 32, below, its oblique guiding groove 62 is enclosed within on the post 324 of supporting plate.

Tiltedly tongue mechanism is that oblique tongue 41 is fixed on the leading axle 42, leading axle 42 inserts in the vertical channel 431 of the stator 43 that is fixed on housing, between stator 43 and oblique tongue spring 44 is set, leading axle 42 other ends are sliding part 45 fixedly, leading axle one side is provided with handle rotating shaft 46, the projection 461 of handle rotating shaft places in the fixture 45, and leading axle 42 heads are established

retainer plate

47, and 45 of retainer plate 47 and sliding parts have spring 48.

As shown in Figure 3, Figure 4, locking 2 lock cores is bilateral pair of pellet shot from a slingshot, be fixed on the lock box 1 by locking bar 24, two side keyhole tops are stator 25, stator 25 is fixed on the lock core by spring 26, the centre is a shift fork 22, with be connected transmission mechanism between handle, projection 461 opposite sides of handle rotating shaft 46 have another projection 462, cooperate with the hook 91 of rotatable lamella 9 one sides, rotatable lamella 9 is positioned on the locking closure by axle 92 and by gathering sill 93 and post 95 guiding, opposite side is a pawl 94, cooperate with shift fork 22, shift fork 22 is movably connected on the tapered end by stator 25.

Lock also with common insurance institution 8, tiltedly the tongue link gear.

When locking, when key is inserted a side chain core, promote a side stator, back down the stator of opposite side, therefore the lock core of inserting the key side can drive shift fork 22 and rotate, shift fork 22 promotes location-plates 33 earlier, makes the projection of location-plate 33 leave groove 323 on the supporting plate 32, and shifting block 22 promotes the opening groove 321 of supporting plate 32 again, lock just moves forward, last dead bolt exposes fully, and the projection of location-plate 33 is embedded in the groove 323 on the supporting plate 32, fixedly dead bolt.

When unblanking, when key is inserted a side chain core, promote a side stator, back down the stator of opposite side, therefore the lock core of inserting the key side can drive shift fork 22 counter-rotation, shift fork 22 promotes location-plates 33 earlier, makes the projection of location-plate 33 leave groove 323 on the supporting plate 32, and shift fork 22 drives the opening groove 321 of supporting plate 32 again, lock just moves backward, last dead bolt is fully retracted, and the projection of location-plate 33 is embedded in the groove 323 on the supporting plate 32, fixedly dead bolt.

After unblanking, when not inserting key, shift fork can freely rotate.Rotate with handle, its projection drives intermediate slider and rotates, and rotates thereby drive shift fork, and shift fork promotes location-plate 33 and then dead bolt is locked into.At dead bolt and lock seaming conducting mechanism is set, can sends the sound that door has locked when door lock is good.If do not lock, doorbell then can not emitted such sound.When this moment, door key inserted a side chain core, promote a side stator, back down the stator of opposite side, the lock core of therefore inserting the key side can drive shift fork and rotate, and counter-rotation just can be unblanked again.
