Description
Technical field
The present invention relates to a kind of theftproof lock, in particular, it relates to a kind of spiral prominence wall, recess positioned drill-preventive anti-theft lock.
Background technology
The patent No.: 200420079009.2 or 200620074427.1 and market on existing theftproof lock, key is spiral-shaped with coordinating of lock core key, key hole slot inside spin is arranged with pellet or lock pin or various difform pellet, at the bottom of each of keyhole helicla flute, between two walls, width to width between notch two walls is equal, become parallel shortcoming on the trough wall surface of spiral fluted both sides, become the space of two parallel slot walls not hinder setting, make various unlocking tools facilitate move operation or facilitate combination tool to overlap to unblank.Lock core has the slot of two separated screw types at least, make to have at least on the key two separated spiral inserting columns can exchange respectively reeve slot allotment examination cover and praise interface tooth pitch and unblank, and have the key of two separated screw type inserting columns at least with taking easy deformed damaged with oneself.At lock core tail end, be provided with longitudinal setting of lock pin location, make lock core too thicken growth, be unfavorable for being arranged on thin door leaf.Lock core arranges the anti-drilling framework of spiral, and is arranged on the periphery of lock core circumference, but is not protected in the inner position of lock core key hole body.
Summary of the invention
The object of the invention is to overcome the deficiencies in the prior art; prevent that technical and violence nature from unblanking; adopting bent assorted cooperation of protruding wall recess with lock core key hole slot on the key; and at keyhole, the trapezoidal anti-drilling post of spiral is set; and lock core tail end arranges alignment pin; hinder the firm protection setting of stealing tool operation and stoping lead plug, and a kind of spiral prominence wall recess positioned drill-preventive anti-theft lock is provided.
For reaching above-mentioned purpose, technical scheme of the present invention is:
Spiral prominence wall, a recess positioned drill-preventive anti-theft lock, be comprised of lock body, lock core, pellet, spring, key etc., wherein: and the helicla flute of at least one protruding wall, recess shape in lock core, and described helicla flute is 180 degree helicla flutes; At least form on the key a protruding mirror recessed mirror helical arrangement tooth or shell hole tooth, and spiral is 180 degree spirals; Described lock core also has at least marble hole of shape screw type in a row, and marble hole also has the pellet of arranging respectively; Described lock body also has the interface marble hole of screw type, and described marble hole also has the interface pellet of arranging respectively; In the protruding wall of described lock core, recess helicla flute, at least form the trapezoidal anti-drill flute of a screw type, and described trapezoidal anti-drill flute is large notch by lock core tail end direction, and described large notch dwindles gradually and extends the small-rabbet that is trapezoidal anti-drill flute to plug face extreme direction, described trapezoidal anti-drill flute also has the trapezoidal anti-drill string of the screw type of being placed in, and described trapezoidal anti-drill string is microcephaly, and described little Certificates closes small-rabbet and increases and extend to large notch gradually, and described large notch is the major part that has trapezoidal anti-drill string; Described key injects lock core positioner is set.
Described lock core tail end also has locating hole, and described locating hole also has the alignment pin being placed in, and described alignment pin also has locating latch and touches face.Described key tooth top also has locating latch and lifts tactile face, and the gradient that locating latch is lifted the face of touching is for touching the gradient of face to joining locating latch.Described lock body also has interface locating hole, and described interface locating hole also has the interface alignment pin being placed in.Described trapezoidal anti-drill string is No. 45 hardened steel.
The advantage that the present invention has anti-theft effect is:
1, the groove of keyhole is the assorted formation of the spiral-shaped song of protruding wall, recess, hinders stealing tool and can not move adjusting insurance tooth pitch and must not open lock in upper and lower, left and right in protruding wall, recess helicla flute.
2, key hole slot at least forms a protruding wall, recess or biconvex wall, concave-concave wall to arranging helicla flute, and protruding or recessed position and standoff distance and direction are arranged different, the shape that is key hole slot is arranged winding complex, non-key is difficult for injecting in key hole slot, and the combination tool change shape of theft and be not easy to inject keyhole and go to use and unblank.
3, lock core arranges spiral-shaped trapezoidal anti-drill string, and trapezoidal anti-drill string Let is combined in the circumference in keyhole, and pellet and the alignment pin of protection lock core are not destroyed by lead plug.
4, the anti-drill string of ladder type that is provided with concentric reducer spiral is pushed up respectively and is combined in lock core and is provided with in the anti-drill flute of the spiral ladder type of large small-rabbet, and the major part direction Let of trapezoidal anti-drill string is combined on the large notch of trapezoidal anti-drill flute of lock core tail end, by plug face end aspect, be provided with the reduced major part that blocks the anti-drill string of ladder type on the small-rabbet of trapezoidal anti-drill flute, and can not lead plug lock core, cannot prize trapezoidal anti-drill string simultaneously.
5, lock core afterbody top arranges alignment pin is housed, and making key must inject the alignment pin on lock core top could compound interface alignment pin, and limit key can not move forward and backward regulating tooth apart from and the effect that obtains.
6, the alignment pin of lock core is provided with locating latch and touches face, and the locating latch of tiltedly lifting the face of touching and lock core that limits key touches the face compound positioning action again that matches, and makes various unlocking tools be inconvenient to operate stir and insure tooth pitch and must not unblank in lock core top again.
