Abstract

The utility model relates to a lock core with two keys, the current lock core is single key type, which can be easily hitched or unclenched so as to be not safe, the utility model aims at designing a lock core with two keys consisting of three layers of a core shell, a main lock core and a safe core. The safe core(6) is arranged inside the main lock core(9), one of the two cores must be bigger than the other one. The marbles in the lock core must be arranged at least three routes, which are unlocked by two sheet of keys respectively, the subsidiary length sum of the first, the third and the forth route must be bigger than the thickness sum of the main lock core and the safe core, so that when the lock is in B key state, to protect the safe core and the main lock core do not rotate. The utility model has the advantages of good function of preventing hitching and unclenching, safe reliability, and the utility model is suitable for important safe place and appliance of vehicle doors, safes and vault doors.

Description

Double key lock core

The utility model relates to a kind of improving technology Double key lock core of articles for daily use lock.

As everyone knows, lock is the indispensable product of people's articles for daily use, and existing lock all is single lock core, often exists the defective that the easy quilt cover of lock core is opened, and very dangerous, people wish to have a kind of firm lock that quilt cover is opened, pried open that is difficult to.

The purpose of this utility model provides a kind of Double key lock core for overcoming above-mentioned weak point, and it is antitheft, pick-proof, performance are good, safe and reliable.

The utility model is this realization, Double key lock core be two different key operated same lock core, this lock core overcomes the easy quilt cover of general lock core greatly and opens, the defective of prying open, about the increasing diameter of the general lock core of the diameter of its main lock core is twice, its pick-proof performance is greatly improvement especially, Double key lock core is compared one deck lock cores that increase more with conventional lock cylinders, key operated by two, two lock cores, two lock core common points are in a lockhole, two ways and four ways are fixed length cylindricality (or rectangle) pellet shot from a slingshot in the Double key lock core, one way is indefinite eldest son, but but also random length of three way fixed length, if three way fixed length, the thread form of so big or small key is identical, if random length size spoon thread form is different.A way, three ways in the lock core, four way length sums must be greater than the wall thickness sum of main lock core and safe core, and the side is protected when B lock point sky spoon state, and safe core and main lock core can not rotate.Double key lock core mainly is made of for three layers safety core, main lock core, core ectosome, has four tunnel cylindricality pellets shot from a slingshot, the collaborative unlatching (lock core must be made of pellet shot from a slingshot more than three tunnel) of finishing A, B lock point key.The angle difference of A, B lock point can cause 45 degree, 135 degree etc.

Below in conjunction with Figure of description the utility model is described in detail

Fig. 1: be the empty spoon view of the utility model lock point

Fig. 2: for the little spoon of the utility model skewer is gone into view

Fig. 3: for the utility model large spoon skewer is gone into view

Double key lock core of the present utility model, it is by core ectosome (1), spring (2), four ways (3), shutoff tin bar (4), three ways (5), safe core (6), one way (7), two ways (8), main lock core (9), core housing 10 is formed, this lock is established safe core, main lock core, three layers of core ectosomes, lock core must small one and large one, in core housing (10), be provided with main lock core (9), in the main lock core (9) of core housing (10) central authorities, be provided with safe core (6), pellet shot from a slingshot is made of pellet shot from a slingshot more than three tunnel in the lock core, one way (7), two ways (8), three ways (5), four ways (3) are arranged in the lock core, two ways (8) and four ways (3) are fixed length cylindricality (rectangle) pellet shot from a slingshot in Double key lock core, one way (7) is indefinite eldest son, three ways (5) but but also random length of fixed length, if three way fixed length, the thread form of that big or small key is identical, different as the big small spoon tooth open form of random length, way (7) in the lock core, three ways (5) but but also random length of fixed length, if three way fixed length, the thread form of that big or small key is identical, different as random length size spoon thread form, way (7) in the lock core, three ways (5), four ways (3), the length sum must be greater than the wall thickness sum of main lock core (9) and safe core (6), the side is protected when B lock point sky spoon state, and safe core (6) and main lock core can not rotate.Four kinds of states of lock core coexistence, the empty spoon of A lock core state (as Fig. 1), little spoon skewer is gone into state (as Fig. 2), the large spoon skewer is gone into state (as Fig. 3), the empty spoon state of B lock point (figure slightly), the empty spoon of an A point state be empty spoon end-state, inserts little spoon after, the small spoon tooth flower overlaps equals a way, rotatable first floor lock core (being safe core) is to B lock point, extract little spoon out at B lock point, insert large spoon again, when large spoon inserts, the horizontal bolt of one way is between safety core and main lock core, on the safe core on a way and the main lock core three ways add up the cover flat large spoon tartar, could rotate main lock core, could rotate main lock core, reach the purpose of unblanking, large spoon must be inserted by little topic and turn to A lock point after B lock point is extracted out when locking, and comes to an end in the whole process side of locking.

Double key lock core of the present utility model is widely used in important safety places such as security door, automotive door, safety cabinet, national treasury gate and apparatus, its applicability is strong, and safe effect is good.
