The combination of tapered end and key and using method thereof
Technical field
The present invention relates to field of lockset, is specifically combination and the using method thereof of a kind of tapered end and key.
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, provides a kind of lock core sectional design, and opener is difficult to the combination that straight cutting encounters pellet assembly, technology unlocking difficulty is large, theftproof performance is good tapered end and key.
For solving the problems of the technologies described above, the combination of tapered end provided by the invention and key, comprise tapered end and key, key comprises and is flat the shank of the key and key body, the tow sides of key body are equipped with the different tartar of multiple degree of depth of distributing along its length, tapered end comprises housing, lock core body and the pellet assembly matched with the tartar on key body, lock core body axially offers keyhole along it, described lock core body comprises vertically spaced first paragraph lock core body successively, second segment lock core body and the 3rd section of lock core body, the first connector and the elastic connecting device for rotating reset is provided with between first paragraph lock core body and second segment lock core body, the second connector and the elastic connecting device for rotating reset is provided with between described second segment lock core body and the 3rd section of lock core body, two described elastic connecting devices including extension spring for connecting adjacent two-phase lock core body, one end of extension spring being fixed on the upper alignment pin of the preceding paragraph lock core body and the other end of extension spring being fixed on the lower alignment pin of next section of lock core body, the first connector and the second connector are equipped with the deep-slotted chip breaker for accommodating extension spring, the equal separated time B of the first described connector and the keyhole width of second segment lock core body is that the equal separated time A of the keyhole width of first paragraph lock core body rotates 90 ° in the counterclockwise direction, and the equal separated time C of the keyhole width of the second described connector and the 3rd section of lock core body is that the equal separated time A of the keyhole width of first paragraph lock core body rotates 90 ° along clockwise direction.
As improvement, described second segment lock core body is provided with auxiliary locator, 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 soffit of the first connector and the upper surface of the second connector are respectively equipped with the groove for accommodating steel ball end.
After adopting above structure, the present invention compared with prior art, has following advantage:
The present invention is in the process of unblanking, operator needs segmentation clockwise or could continue after being rotated counterclockwise 90 ° to unblank, and key of the present invention is the two-sided key that common commercially available two sides is equipped with tartar, 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.
In addition, owing to being provided with auxiliary locator, 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.
The invention also discloses the using method of the combination of a kind of tapered end and key, concrete steps are as follows:
1) key body, key to be inserted in the keyhole of lock core body till cannot advance;
2), by key rotate counterclockwise key body after 90 ° to continue 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;
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 the afterbody of lock core body drives plectrum to drive dead bolt to unblank.
After adopting above method, the present invention compared with prior art, has following advantage:
Be different from the straight cutting key unlocking of 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, be then rotated further key and drive lock core body to rotate, 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.
