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 in people's life, apply 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 being linked by lock core and pellet assembly, and lock core is provided with keyhole.Its operating principle is, in the time inserting with the corresponding key of this tapered end, the key flank of tooth and each pellet are corresponding one by one, 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 drive dead bolt to unblank.The lock core of common cylinder lock mostly is integral type, technology unlocking instrument rotates after entering keyhole as straight cuttings such as Unlocking gun, steel disc, screwdrivers, be easy to just can stir the pellet even destroying in lock core, in the short time, just can by force lock be opened, its theftproof performance is poor.
Summary of the invention
Technical problem to be solved by this invention is, a kind of lock core segmented design is provided, and opener is difficult to straight cutting and encounters pellet assembly, technology unlocking difficulty is large, theftproof performance is good tapered end and the combination of 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 distributing along its length, tapered end comprises housing, lock core body and the pellet assembly matching 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, between first paragraph lock core body and second segment lock core body, be provided with the first connector and for rotating the elastic connecting device of reset, between described second segment lock core body and the 3rd section of lock core body, be provided with the second connector and for rotating the elastic connecting device of reset, described elastic connecting device comprises extension spring for connecting adjacent two-phase lock core body, the upper alignment pin of the preceding paragraph lock core body is fixed on in one end of extension spring and the other end of extension spring is fixed on to the lower alignment pin of next section of lock core body, on the first connector and the second connector, is equipped with the deep-slotted chip breaker for accommodating extension spring, the equal separated time A of the keyhole width that the equal separated time B of the first described connector and the keyhole width of second segment lock core body is first paragraph lock core body rotates 90 ° in the counterclockwise direction, and the equal separated time A of the keyhole width that the equal separated time C of the keyhole width of the second described connector and the 3rd section of lock core body is first paragraph lock core body rotates 90 ° along clockwise direction.
As improvement, described second segment lock core body is provided with auxiliary locator, on second segment lock core body, be provided with the mounting groove vertically running through, described auxiliary locator comprises the steel ball that is vertically arranged at the retainer spring in mounting groove and is located at retainer spring two ends, and the upper surface of the soffit of the first connector and the second connector is respectively equipped with the groove for accommodating steel ball end.
Adopt after above structure, the present invention compared with prior art, has advantages of following:
The present invention is in the process of unblanking, operator needs segmentation could continue to unblank clockwise or after being rotated counterclockwise 90 °, 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 be stirred 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 has entered in the first connector, due to the pellet assembly of second segment lock core body and the vertical setting mutually of the pellet assembly of first paragraph lock core body, unlocking tool is difficult to stir the pellet assembly of second segment lock core body, the difficulty of wanting to continue to enter the second connector is larger, cannot stir the 3rd section of pellet assembly in lock core body 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 resetting at lock core body, can utilize the cooperation of the groove that the elasticity of spring and the lower surface of steel ball and the first connector and the upper surface of the second connector be provided with to carry out auxiliary positioning to the first connector, the second connector etc.
The using method that the invention also discloses the combination of a kind of tapered end and key, concrete steps are as follows:
1), key is inserted in the keyhole of lock core body until key body cannot advance;
2), key is rotated counterclockwise in the keyhole that key body after 90 ° continues to insert the first connector, and continue to insert downwards in the keyhole of second segment lock core body, until key body cannot move on;
3), key being clockwise rotated to key body after 180 ° continues to insert in the keyhole of the second connector, and continue to insert downwards the 3rd section of lock core body keyhole in, then be rotated further key and drive lock core body to clockwise rotate 90 °, the afterbody of lock core body drives plectrum to drive dead bolt to unblank.
Adopt after above method, the present invention compared with prior art, has advantages of following:
Be different from the straight cutting key unlocking of prior art, of the present invention unblanking in process, operator is inserting key leading portion until key body cannot advance time, after needing first key to be rotated counterclockwise to 90 °, continue again to insert, until key body is cannot move on time, and then after key is clockwise rotated to 180 °, continue again to insert, being then rotated further key and driving 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.
