Description

A kind of anti-theft lock device

Technical field

The utility model relates to a kind of theftproof lock, a kind of theftproof lock tapered end that can prevent that especially technical unlocking and key from opening mutually specifically.

Background technology

Present theftproof lock divides two kinds of automatic locking and manual locks, mechanical type cylinder lock, magnetic bullet combination lock is arranged, adopt built-in core-inset type structure, all is made up of tapered end and lock body, and blossom type, cross, intelligent etc. is arranged.Computer KC type, except the Fingerprint Lock, whether antitheft key is at tapered end for theftproof lock, though theftproof lock is various in style, tapered end and lock body are in continuous variation, its real know-why does not but become, just shape and the size that change, as existing blossom type theftproof lock, it is to form by tapered end and lock body, tapered end is by lock core, the tapered end cover, the tapered end guard ring, dead bolt, protect tooth, the eyes buckle, wire nail combines, lock body is by lock, oblique tongue, handle, tiltedly tongue is locked the knob composition, it is characterized in that: though tapered end is the blossom type lock core of four faces, key also is the blossom type of four faces, key is worked in coordination and could be opened with the four sides pellet shot from a slingshot, its shortcoming is that lock core and tapered end overlap and pellet shot from a slingshot has certain clearance, regularization too, the pellet shot from a slingshot accuracy is too poor, producing some keys just can open mutually, can not accomplish that every pellet shot from a slingshot all plays effect, this point is the common drawback that exists of all mechanical locksets just also, opening only needs just can easily open fast according to its lock core and instrument of pellet shot from a slingshot theory structure self-control, and lock is still excellent, do not reach the effect of safe antitheft.

Background technology

Technical problem to be solved in the utility model is that the defective at prior art provides a kind of mechanical type pellet shot from a slingshot combination anti-theft lock end remedying the deficiencies in the prior art, and this anti-theft lock end can prevent effectively that technical unlocking and key from opening mutually.

The technical scheme that its technical problem that solves the utility model adopts is: it is made up of tapered end and lock body, tapered end adopts built-in core-inset type structure, it is by key, lock core, the tapered end cover, the tapered end guard ring, dead bolt, protect tooth, the eyes buckle, wire nail combines, it is characterized in that: key is six equilateral teeth, the centre is the cone shape, the key bit of key is a benchmark with article one tooth, distance with a pellet shot from a slingshot is step-like extension, the increment that removes a key bit is a recessed or convex, the increment of all the other five teeth requires to be provided with two dark or shallow recessed or convexs according to reality, the one side of lock core also is to be six equilateral faces, the centre has a circular port corresponding with the cone in the middle of the key, every tooth size of every core groove depth size and key length of six faces of lock core is corresponding mutually, the pellet shot from a slingshot hole is separately positioned on key and injects the recessed or protruding lock core position of key bit increment in the lock core, with two pellet shot from a slingshot holes of first row is that benchmark is step-like setting and extends to the top, the tapered end cover is the standard setting with the lock core, being arranged to per two pellets shot from a slingshot of horizontally-arranged like this cooperatively interacts, the key bit of key does not but disturb mutually, every pellet shot from a slingshot has all played effect, reach some even if produce, the situation that key can be opened mutually can not appear, when other object enters every pellet shot from a slingshot that lock core also can't be found six faces simultaneously accurately, even there be the instrument similar to enter lock core to key, also can't technical opening, because instrument just equals to have broken away from six pellets shot from a slingshot as long as break away from a pellet shot from a slingshot, this technology is existing lockset gap, regularization, the shortcoming of pellet shot from a slingshot accuracy difference changes into advantage, reaches the effect of safe antitheft.

The beneficial effects of the utility model are: doing in pick-proof, anti-drilling, anti-saw, impact force proof, solved to produce and reached some keys and can open defective with technical unlocking mutually, this anti-theft lock end know-why is applicable to various mechanical locksets, easy to use, simple in structure, safe antitheft.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

Contrast Fig. 7 in Fig. 4, the one side of lock core 2 is six equilateral faces, and the other end overlaps 3 front cavitys from tapered end and inserts; Put tapered end guard ring 4, anti-end breach at lock core 2 injects dead bolt 5, protects tooth 6 on the anti-end breach card of lock core 2, buckles eyes buckle 7, load onto wire nail 8, load onto in the pellet shot from a slingshot hole of lock core 2 and tapered end cover 3 with key 1 as requested and can corresponding mutually pellet shot from a slingshot and spring can freely turn round.

Connect lock body Fig. 6 according to tapered end Fig. 4, dead bolt 5 injects among lock body Fig. 6 dead bolt control mouthfuls 15 and gets final product among tapered end Fig. 4.Lock body by lock, tiltedly tongue, tiltedly tongue handle, indoor tapered end, oblique tongue are locked knob, buckle is formed, owner is controlled by key in outdoor lock, oblique tongue, and owner is in indoor, and tiltedly tongue is by the control of oblique tongue handle, as need lock, the moving oblique tongue of button locks knob and gets final product, indoor tapered end also can be opened or be locked.
