Abstract

The utility model relates to a lock with double lock cores. The outer side of a lock core of the existing cylinder lock is added with an external lock core which is provided with an external lockhole. The utility model is characterized in that a juncture which spans an internal lock core and an external lock core is provided with a positioning long cylinder which is pushed by a spring; one side of the internal lock core is provided with a positioning groove which is locked with the positioning long cylinder and can not rotate, and so the lock can not be opened by any unlocking tool; one side of the external lock core is provided with a circumference groove, wherein one end of which is an oblique line and the other end of which is a perpendicular line; when the external lock core is rotated, the end of the oblique line of the circumference groove jacks up the positioning long cylinder in order to cause the internal lock core to be positioned at the rotatable position, and then an external lockhole rotates an angle, so that the upper half part of the internal lockhole is all shielded and can not insert unlocking tools such as universal keys or bend hook steel wires to open the lock. A key with a sleeve handle must be used to open the lock. The outer side of the key is sheathed with the sleeve handle of the key, and the key and the sleeve handle of the key can respectively rotate correspondingly to each other. The outer end of key teeth is provided with a rotating shaft, and the inner end of the sleeve handle of the key is provided with an inserting sleeve which can insert the external lockhole. When the lock is opened, the key with the sleeve handle is inserted into the lock. When the external lock core is rotated to the predetermined position, the end of the oblique line of the circumference groove of the external lock core jacks up the positioning long cylinder in order to cause the internal lock core to be positioned at the rotatable position, and meanwhile, one.

Description

Twin-lock core lock
Technical field
The utility model relates to a kind of cylinder lock, can prevent that especially experienced robber from utilizing master key or crotch steel wire to unblank, and is the splendid twin-lock core lock of theftproof performance.
Background technology
At present, the lock core hole of known cylinder lock all exposes, and experienced robber can insert master key or the crotch steel wire is unblanked, and lacks the sense of security.
Summary of the invention
In order to overcome the deficiency that existing cylinder lock can be opened with master key or crotch steel wire.The utility model provides a kind of twin-lock core lock, and its internal cylinder when latched position has location long marble locking to rotate, and any unlocking tool all can't be opened so don't work this moment.Internal cylinder is in when turning the position, angle of exterior lockhole deflection, and the first half of lockhole also just can't inject the unlocking tool of master key or crotch steel wire and so on and open this lock all by shield in making.Thereby improve degree of safety greatly.
The technical scheme that its technical problem that solves the utility model adopts is: set up an outer lock core that is provided with exterior lockhole outside cylinder of spring lock, be provided with a location long marble that promotes with spring at intersection across interior outer lock core, being provided with the locking of locating slot and above-mentioned location long marble in internal cylinder one side can't rotate, and any unlocking tool that don't work this moment all can't be opened.Be provided with circumferential groove in outer lock core one side, groove one end is an oblique line, the other end is a vertical line, when rotating oblique line end jack-up location long marble that outer lock core makes its circumferential groove when making internal cylinder be in rotatable position, exterior lockhole has turned over an angle, the first half of lockhole all is blocked in making, and also just can't inject the unlocking tool of master key or crotch steel wire and so on and open this lock.Need to open this lock and must use the key that has toggle: be with the key toggle in the key outside, can rotate respectively between the two, the outer end of key bit is provided with rotating shaft, and the inner of key toggle is provided with the sleeve that can insert exterior lockhole.Insert the key of band handle during unlatching, when rotating outer lock core to the precalculated position, the oblique line end jack-up location long marble of outer lock core circumferential groove, make internal cylinder be in rotatable position, meanwhile a wherein end of outer lock core arc blind hole contacts with the internal cylinder alignment pin, internal cylinder is driven together by outer lock core and rotates, until opening this lock.
The beneficial effects of the utility model are: thoroughly stopped to utilize the unlocking tool of master key or crotch steel wire and so on to open this lock, theftproof performance is good, and order is simple and reliable for structure.

The specific embodiment
In Fig. 1, this lock is in latched position, and location long marble (3) inserts internal cylinder locating slot (1b) under spring (4) elastic force promotes, and internal cylinder (1) can't be rotated, so do not insert the key that has toggle shown in the figure, any unlocking tool that don't work all can't be opened this lock.Referring to Fig. 3, make internal cylinder (1) be in rotatable position if manage to rotate the oblique line end jack-up location long marble (3) that outer lock core (2) makes its circumferential groove (2b), exterior lockhole this moment (2a) has turned over an angle, the first half of interior lockhole (1a) all is blocked, also just can't injects the unlocking tool of master key or crotch steel wire and so on and open this lock.
When needing to open this lock (referring to Fig. 1, Fig. 2), key axle (5) is inserted earlier in the interior lockhole (1a), swing key toggle (6) then and make the shank of the key sleeve (6a) aligning exterior lockhole (2a) and insertion wherein, key toggle this moment (6) is swung with key shaft end spheroid (5a) center of circle, make the shank of the key locate flat hole (6b) and break away from the key axle flat axle in location (5b), key toggle (6) can freely be rotated along key axial end spheroid (5a) center of circle.Clockwise direction key toggle (6) is during to the precalculated position (referring to Fig. 3), make the oblique line end jack-up location long marble (3) of outer lock core circumferential groove (2b) make internal cylinder be in rotatable position, meanwhile a wherein end face of outer lock core arc blind hole (2c) contacts with internal cylinder alignment pin (1c), internal cylinder (1) is driven together by outer lock core (2) and rotates, until opening this lock.
In the time of need extracting key (referring to Fig. 1, Fig. 3), counterclockwise key toggle (6) drives exterior lockhole (2a) rotation by the shank of the key sleeve (6a) earlier, internal cylinder alignment pin this moment (1c) moves in outer lock core arc blind hole (2c), internal cylinder (1) is not rotated, the other end until outer lock core arc blind hole (2c) contacts with internal cylinder alignment pin (1c), and internal cylinder (1) is driven together by outer lock core (2) and rotates.Until initial latched position (referring to Fig. 2, Fig. 1), the inboard of location long marble (3) is relied on by internal cylinder (1) cylindrical no longer and falls in the internal cylinder locating slot (1b), internal cylinder (1) locking can't be rotated further again, meanwhile, the outside of location long marble (3) promptly with the vertical line end in contact of outer lock core circumferential groove (2b), make outer lock core (2) can't continue counterclockwise to rotate, can extract key toggle (6) this moment.
After the key that has toggle is all extracted (referring to Fig. 4), under the elastic force effect of spring (8), the short pellet shot from a slingshot in location (7) promotes key axle (5) and swings along key axial end spheroid (5a) center of circle, make the flat axle of key positioner (5b is simultaneously referring to Fig. 2), enter the shank of the key and locate flat hole (6b, simultaneously referring to Fig. 2), with key axle (5) locking, make key axle (5) and key toggle (6) be unified into a motionless integral body, be easy to carry.
