Description
Technical field
The present invention relates to field of lockset, particularly the assembly of a kind of anti-theft key and tapered end and using method thereof.
Background technology
At present, the lockset on market of a great variety, configurations, what wherein apply in the life of people is cylinder lock the most widely.The tapered end of cylinder lock of the prior art is mostly made up of lock body, lock core, the plectrum linked by lock core and pellet assembly, and lock core is provided with keyhole.Its operating principle is, when inserting the key corresponding to this tapered end, the key flank of tooth and each pellet one_to_one corresponding, make the height of each pellet be in the contact surface place of lock body and lock core, then rotational lock core can drive plectrum to drive dead bolt to unblank.The lock core of common cylinder lock mostly is integral type, technology unlocking instrument as the straight cuttings such as Unlocking gun, steel disc, screwdriver enter keyhole after rotate, be easy to just can stir the pellet even destroyed in lock core, just can be opened by lock by force in the short time, its theftproof performance is poor.
Summary of the invention
Technical problem to be solved by this invention is: provide a kind of lock core sectional design, and opener is difficult to the assembly that straight cutting encounters pellet assembly, technology unlocking difficulty is large, theftproof performance is good anti-theft key and tapered end.
The present invention's adopted technical scheme that solves the problem is: the assembly of a kind of anti-theft key and tapered end, comprise key and tapered end, described key comprises flat the shank of the key and key body, and the side of described key body is provided with the tartar of the asymmetrical shape distributed along its length; Described tapered end comprise housing, with the lock core body that matches of tartar on key body and pellet assembly, described lock core body offers keyhole vertically, described lock core body comprises vertically spaced first paragraph lock core body, second segment lock core body and the 3rd section of lock core body successively, being provided with the first connector and the elastic connecting device for rotating reset between described first paragraph lock core body and second segment lock core body, between described second segment lock core body and the 3rd section of lock core body, being provided with the second connector and the elastic connecting device for rotating reset;
Two elastic connecting devices include extension spring, for being connected and fixed the upper alignment pin of upper end and the lower alignment pin for being connected and fixed lower end, the first described connector and the second connector are equipped with the deep-slotted chip breaker for accommodating extension spring;
Between the axis of the axis of the first described connector and the keyhole cross section of second segment lock core body and the keyhole cross section of first paragraph lock core body, angle is in the counterclockwise direction 90 °; Between the axis of the axis of the keyhole of the second described connector and the 3rd section of lock core body and the keyhole cross section of first paragraph lock core body, angle is along clockwise direction 90 °.
Compared with prior art, the invention has the advantages that: the lock core body of the assembly of this anti-theft key and tapered end is sectional design, two connectors and the elastic connecting device for rotating reset is respectively arranged with between each section of lock core body, and angle is in the counterclockwise direction 90 ° (namely the first connector is arranged with the keyhole of second segment lock core body is vertical with the keyhole of first paragraph lock core body) between the axis of the keyhole cross section of the first connector and second segment lock core body and the axis of the keyhole cross section of first paragraph lock core body, between the axis of the axis of the keyhole of the second connector and the 3rd section of lock core body and the keyhole cross section of first paragraph lock core body, angle is along clockwise direction 90 ° (i.e. the keyhole of the second connector and the 3rd section of lock core body and the keyhole of the first connector and second segment lock core body are 180 ° arrange).Unblank in process, operator needs segmentation clockwise or could continue after being rotated counterclockwise 90 ° to unblank.And key of the present invention is common commercially available unidirectional key, tapered end is also as good as with common lock on the surface, but general technology unlocking instrument can only stir the pellet assembly of the first paragraph lock core body in this lock core body, be difficult to enter the first connector, even if technology unlocking instrument enters in the first connector, due to the pellet assembly of second segment lock core body and the pellet assembly of first paragraph lock core body is mutually vertical arranges, unlocking tool is difficult to the pellet assembly stirring second segment lock core body, want that the difficulty continuing to enter the second connector is then larger, the pellet assembly in the 3rd section of lock core body cannot be stirred at all, technology unlocking instrument cannot be played a role, there is good theftproof performance.
As preferably, described second segment lock core body is provided with auxiliary locator, described second segment lock core body is provided with the mounting groove vertically run through, described auxiliary locator comprises the retainer spring be vertically arranged in mounting groove and the steel ball being located at retainer spring two ends, and the lower surface of the first described connector and the upper surface of the second described connector are respectively equipped with the groove for accommodating steel ball end.Like this, rotate in the process resetted at lock core body, the cooperation of the groove that the upper surface of the lower surface of the elasticity of spring and steel ball and the first connector and the second connector can be utilized to be provided with carries out auxiliary positioning to the first connector, the second connector etc.
A using method for the assembly of anti-theft key and tapered end, concrete steps are as follows:
1), by key insert in the keyhole of lock core body till key body cannot advance, now the front end of key body contacts with the end face of the first connector;
2) key being rotated counterclockwise key body after 90 ° continues in the keyhole of insertion first connector, and continue to insert downwards in the keyhole of second segment lock core body, till key body cannot move on, now the front end of key body contacts with the end face of the second connector;
3) key being rotated clockwise key body after 180 ° continues in the keyhole of insertion second connector, and continue to insert downwards the 3rd section of lock core body keyhole in, then being rotated further key drives lock core body to rotate clockwise 90 °, and lock core afterbody drives plectrum to drive dead bolt to unblank.
Compared with prior art, the invention has the advantages that: the straight cutting key unlocking being different from prior art, of the present inventionly unblank in process, operator insertion key leading portion until when key body cannot advance, continue again to insert after needing first key to be rotated counterclockwise 90 °, until when key body cannot move on, and then continue again after key is rotated clockwise 180 ° to insert, then being rotated further key drives lock core body to rotate, and lock core afterbody drives plectrum to drive dead bolt to unblank.Technology unlocking instrument is difficult to imitate this process of unblanking, and technology unlocking difficulty is large, theftproof performance good.
