Summary of the invention
Purpose of the present invention provides a kind of more safe and reliable theftproof lock in order to solve the weak point of above-mentioned technology.
For this reason, the technical solution used in the present invention is as follows: theftproof lock, comprise lock body, and be provided with flat tongue assembly and oblique tongue assembly in the lock body, tiltedly the tongue assembly comprises shifting block and the oblique tongue rod that has spring, shifting block rotates and stirs oblique tongue rod by handle; Comprise flat dead bolt and one and the vertical pole of flat dead bolt interlock in the flat tongue assembly; It is characterized in that: described shifting block is made up of inside and outside two-layer annulus, links to each other with spring pin with pin-and-hole between the ectonexine, and internal layer annulus and handle are fixedly linked, and outer annulus is fixed with the struck side, matches with oblique tongue rod; Be fixed with an inclined-plane on the described vertical pole, match with spring pin in the shifting block.
Specifically, the mode that the inclined-plane on the vertical pole cooperates with spring pin in the shifting block is such: an end on described inclined-plane, and the outer annulus of its movement locus and shifting block is tangent; The other end on described inclined-plane, the outer annulus of its movement locus and shifting block from.
The movement locus of so-called inclined-plane one end, its implication is as follows: because vertical pole and the interlock of flat dead bolt, the also inevitable motion of thereupon making a certain direction in inclined-plane fixed thereon is so each point on the inclined-plane all has movement locus separately.
After adopting technique scheme, the present invention is under normal situation about using, open the lock with the key, then flat dead bolt indentation, vertical pole links with it, to the motion of a certain direction, the inclined-plane on the vertical pole move to the outer annulus of shifting block from, spring pin is stretched out from pin-and-hole by the effect of spring force, connects the ectonexine annulus of shifting block; At this moment, rotate handle and can make the internal layer annulus drive outer annulus, drive the struck side then and rotate, and further drive oblique tongue rod, open oblique tongue.When shutting with key, flat dead bolt stretches out, and vertical pole links with it, motion round about, and the inclined-plane on the vertical pole moves to the outer annulus of shifting block tangent, and spring pin is pressed in the pin-and-hole, makes the ectonexine annulus lose connection; At this moment, rotation handle then internal layer annulus can only dally, and can not drive outer annulus, and outer annulus still remains static, and tiltedly tongue also can't be opened.
The present invention is under improper situation, when in case flat dead bolt is subjected to the external force effect destroyed, vertical pole can't be subjected to external force and move, and still is in original position, and spring pin still keeps the state of being pressed into, the ectonexine annulus is disjunct, this moment as rotation handle, then the internal layer annulus can not drive outer annulus, can only dally, outer annulus still remains static, and tiltedly tongue also can't be opened.
Vertical pole of the present invention is not limited to moving up and down of vertical direction, also can be the motion of other directions.
Compared with prior art, oblique tongue of the present invention can be subjected to still can maintain the lock status under the ruined situation of external force effect at flat dead bolt, can play good antitheft effect, has promoted the anti-theft effect of theftproof lock.
