Abstract
The utility model relates to a mechanical lock core with a self-locking device, which comprises a lock sleeve (1) and a lock core (2), wherein the lock core (2) is arranged inside the lock sleeve (1); the lock core (2) is divided into front and rear sections (21, 22); and common marbles (27) are arranged on the side walls of the front section (21), the rear section (22) and the lock sleeve (1). The mechanical lock core with the self-locking device is characterized in that semi-circular marble holes (23, 24) are formed in the side walls of the longitudinal same side of the contact parts of the front section (21) and the rear section (22) of the lock core (2) respectively; and the common marbles (26) are arranged in the corresponding position of the lock sleeve (1). With the adoption of the utility model, the problem that a common door lock is easy to unlock is solved; and the lock core is divided into two sections and self-locking marbles and marble holes are arranged between the contact surfaces of the two sections, so that technical opening of a lock body can be avoided completely, the self-locking effect is achieved and a person who wants to unlock the lock does not know where to start.
Description
Technical field
The utility model relates to a kind of lock core, particularly a kind of lock core with self-locking device.
Background technology
The mechanical cylinder lock cost is low, technology maturation and be subject to extensive use.Mechanical cylinder lock is because principle is simple, and structure is uncomplicated, is easy to by technical unlocking, has certain closed end in safety.People have designed the two-part combined lock core for this reason, the lock core that is about in the lock core is divided into two sections, only have when key inserts in the keyhole and is inserted into the position and lock body could be opened, adopt this structure greatly to improve the difficulty of unblanking, but still can be opened from this lock of principle.
Summary of the invention
The purpose of this utility model provides a kind of lock core of self-locking device, and it respectively is designed with semicircular self-locking hole by adopting two segments combined design in the side of two-phase lock core contact.When the person of unblanking unblanks exploratory ground rotational lock core, the semicircular self-locking hole of two-phase lock core can synthesize a complete circular hole, and the pellet that is arranged on the lock tube just can fall into circular hole, and whole like this lock just can automatic locking, unless lock body is all damaged, otherwise can't again lock be opened.
The utility model passes to lower technical scheme and realizes: the utility model is comprised of lock tube and lock core, wherein lock core is arranged in the lock tube, wherein lock core is divided into two sections of front and back, two sections sidewalls with lock tube are equipped with pellet commonly used in front and back, improvements of the present utility model are to be respectively equipped with semicircular marble hole on the sidewall of the vertical homonymy in contact position of the leading portion of lock core and back segment, the opposite side of lock core leading portion is provided with two semicircular marble holes, the lock core back segment is provided with a semicircular marble hole, and the corresponding position on lock tube is provided with common pellet.
Wherein the marble hole of leading portion and back segment staggers under the state that key just commonly used is opened or pinned mutually.If be not with key when unblanking but employing instrument when stirring lock core, must dial first the pellet of leading portion sidewall, then exploratory rotation judges whether pellet is pushed the position, because it only has leading portion to rotate with its instrument when rotating, the semicircle marble hole of its semicircle marble hole and back segment forms a complete circular hole just, pellet on the lock tube sidewall slips under the effect of spring in the circular hole of marble hole composition just, lock core leading portion and back segment are connected as a single entity after slipping into, because back segment still has the pellet shelves to live, this moment, lock core can't rotate again, whole lock core is namely damaged by self-locking, even there is key also can't open.
Adopt the utility model can solve the problem that common door lock is easily pushed aside, it is by being divided into lock core two sections and be provided with self-locking performance pellet and marble hole between two sections contact surface, can prevent thoroughly that lock body from also can be reached the effect of self-locking by technical unlocking, have no way of doing it the person of unblanking.

The specific embodiment
Below in conjunction with accompanying drawing the utility model is further described: the utility model is comprised of lock tube 1 and lock core 2, wherein lock core 2 is arranged on the inside of lock tube 1, wherein lock core 2 is divided into two section 21 of front and back, 22, in front and back two section 21,22 are equipped with pellet commonly used 27 with the sidewall of lock tube 1, wherein be respectively equipped with semicircular marble hole 23 on the sidewall of the contact position homonymy of lock core 2 leading portions 21 and back segment 22,24, corresponding position on lock tube 1 is provided with general pellet 26, the opposite side of lock core leading portion 21 is provided with two semicircular marble holes 24,25, the lock core back segment be provided with a semicircular marble hole 23 wherein the marble hole of leading portion 21 and back segment 22 under the state that key just commonly used is opened or pinned, mutually stagger, consult shown in Figure 1.If be not with key when unblanking but employing instrument when stirring lock core, must dial first the pellet of leading portion 21 sidewalls, then exploratory rotation judges whether pellet is pushed the position, because it only has leading portion to rotate with its instrument when rotating, the semicircle marble hole 24 of its semicircle marble hole 23 and back segment 22 forms a complete circular hole just, pellet 26 on lock tube 1 sidewall slips under the effect of spring in marble hole 23 and 24 circular holes that form just, lock core leading portion 21 is connected as a single entity with back segment 22 after slipping into, because back segment still has the pellet shelves to live, this moment, lock core 2 can't rotate again, whole lock core 2 is namely damaged by self-locking, even there is key also can't open.
For reaching better safe effect, prevent that the thief from constantly souning out, allow it beat a retreat in the face of difficulties, being provided with two semicircular marble holes 24,25, two semicircular marble holes 24, being listed in the both sides of semicircular marble hole 23 in 25 corresponding minutes at the back segment 22 of lock core 1.
Sensitivity when being similarly further enhancing lock and being forced to open attempts to allow the person of unblanking abandon rapidly souning out, and the opposite side of leading portion 21 lock cores of the present utility model is provided with two semicircular marble holes, and back segment is provided with a semicircular marble hole.
