Abstract
The invention discloses a spiral long-short oblique wall positioning anti-drilling anti-theft lock. At least two oblique-edged spiral teeth or tumbler hole teeth different in length are formed on a key, at least two oblique-wall spiral grooves different in length are formed in a matched lock cylinder keyhole, tumblers respectively arranged in a lock cylinder can be reset, different keys can be inserted into the keyhole, and a barrier combination tool operates. At least one spiral slot is formed in the lock cylinder key and is provided with inner acute angles and outer acute angles, a spiral anti-drilling strip is disposed in the slot provided with a right inner acute angle, a right outer acute angle, a left outer acute angle and a left inner acute angle, and the lock cylinder is integrated with the anti-drilling strip and cannot be pulled out and drilled. A positioning pin is disposed at the tail end of the lock cylinder, a slide pin in a slide pin hole is connected into a slide groove, a pushing spring disposed at the tail end pushes against the positioning pin, and accordingly when the key is inserted into the key cylinder and pushes away the positioning pin, telescopic positioning of the positioning pin is achieved to achieve the beneficial anti-theft effect.
Description
Technical field
The present invention relates to a kind of theftproof lock, more particularly, he relates to a kind of spiral length skew wall positioned drill-preventive anti-theft lock.
Background technology
Existing theftproof lock on market, key is screw type shape or linear pattern shape with coordinating of lock core keyhole, keyhole inside spin is arranged with pellet or sheet pin or various pellet, between each of keyhole spiral fluted bottom land two wall, width to width between notch two walls is equal, and the length of every groove also equates, but there is the shortcoming that cell wall both sides are parallel and length is equal, make not hinder barrier setting in every groove of keyhole, make the convenient combination robber of various unlocking tools tool launch operating sleeve and unblank.Lock core has at least two separated screw type slots also to exist equal, make to have at least on the key two separated inserting columns to exchange respectively to inject to regulate insurance tooth pitch in slot and unblank, and have the key of two separated screw type inserting column thickness at least with taking easy modification damage with oneself.Be provided with longitudinal setting of lock pin location at lock core tail end, make lock core too thicken growth, be unfavorable for being arranged on thin door leaf.At lock core, anti-drilling anti-framework is set, and the circumferential edge that is only arranged on lock core periphery is along upper, anti-drilling but the inside of lock core keyhole does not obtain.
Summary of the invention
A kind of spiral length skew wall positioned drill-preventive anti-theft lock, is made up of lock body, lock core, pellet, spring, key etc., wherein: in lock core, at least form two skew wall helicla flutes of length such as not, and described skew wall helicla flute is 180 degree helicla flutes; At least form on the key two hypotenuse helical arrangement tooth or the shell hole teeth of length such as not; And described spiral is 180 degree spirals; Described lock core is the marble hole of shape screw type in a row at least, and described marble hole also has the pellet of arranging respectively; Described lock body is provided with the interface marble hole of screw type, and described interface marble hole also has the interface pellet of arranging respectively; Described lock core also has and at least forms cracking of a screw type, and described in crack to be and have interior acute angle and outer interior acute angle; Described lock core also has and is placed in anti-drilling of the screw type of cracking, and described anti-drilling is and has the right face acute angle and the outer acute angle of the right face and left side face acute angle and the outer acute angle of left side face; Described key injects lock core positioner is set.
Described lock core tail end is provided with allocation pin-and-hole, and described dowel hole also has sliding tray, and described dowel hole also has the alignment pin being placed in.Described alignment pin arranges sliding pin hole, and described sliding pin hole also has the sliding pin being placed in, and the link of described sliding pin is placed in sliding tray.Described sliding tray tail end is provided with top spring, and described top spring stretching by top alignment pin.Described anti-drilling is that No. 45 steel are through quenching.
Advantage of the present invention:
1, the groove of keyhole is the length screw type shape such as not, makes different keys can not inject keyhole regulating tooth distance.
2, the groove of keyhole is spiral skew wall type shape, and the skew wall orientation of every groove is on different trough wall surfaces, make the hypotenuse thickness of the every row's tooth of key unequal, and thickness hypotenuse is different from the orientation of thickness hypotenuse, become non-key and can not inject keyhole adjusting insurance tooth pitch, resistance barrier is stolen tool combined transformation type shape reeve keyhole simultaneously.
3, lock core arranges the upper Let of cracking of screw type and has closed anti-drilling, makes in lock core to obtain to the peripheral entirety of lock core anti-drilling, and protection lock core and pellet and alignment pin are not destroyed by lead plug.
4, the lock core limit of cracking is provided with interior acute angle and outer acute angle, and be combined in lock core with acute angle phase Let outside acute angle and the left side in acute angle and the left side outside acute angle and the right side in the left side of anti-drilling setting and crack to be and have the anti-hafnium bar of concave, convex type shape in aggregates, obtain transfering to anti-drilling and more favourable resistance barrier to be destroyed by lead plug.
5, lock core tail end is provided with alignment pin, and alignment pin afterbody is leaned by top spring, make key inject lock core top and move back alignment pin, become alignment pin to shrink to be and have re-entrant angle to bitting top wedge angle, key and various stealing tool can not be matched to joining on lock core top, become loosening and just obtain the coak locating effect of alignment pin a little backward.
