Abstract
A flexible security lock is to avoid being unlocked by unconventional key, the flexible security lock this utility model comprises an interior key cylinder, an exterior key cylinder, a lock body and a bolt, the said key cylinders are double or multiple structure which can rotate respectively, the back end of the interior key cylinder rotates with the bolt. This utility model is simple, easy to process, and reliable. It can prevent forcing a revolving force on the lock hole, and make a bit shift between the interior key cylinder and the exterior key cylinder, then insert the tool such as the steel wire to avoid being unlocked by unconventional way.
Description
Technical field:
A kind of flexible lock of the utility model relates to a kind of lockset.
Background technology:
Existing traditional lockset safety is low, and the common master worker that unblanks makes inner key cylinder and exterior key cylinder generation certain displacement amount by lockhole being applied a revolving force, re-uses instrument such as steel wire and stretches into lock core and stir pellet shot from a slingshot.Because inner key cylinder and exterior key cylinder have certain displacement, pellet shot from a slingshot is by in the pellet shot from a slingshot hole of the original inner key cylinder that can not be rebounded after having dialled, lose the effect of locking, stir pellet shot from a slingshot in the inner key cylinder repeatedly by instrument, when all last pellets shot from a slingshot are all dialled pellet shot from a slingshot hole from inner key cylinder, inner core can rotate, and makes the displacement of the relative rotation with outer core of inner core less than 90 degree.Use other instrument filling inner key cylinder and rotation lock inner core just to reach the purpose of unblanking.The skilled master worker that unblanks can open common lockset in this way in 10 minutes.
Summary of the invention:
The purpose of the utility model lock is to propose a kind of lockset of being opened by unconventional key avoided.A kind of flexible lock of the utility model is to be made of inner key cylinder, exterior key cylinder, lock body, dead bolt etc., it is characterized in that described inner key cylinder is two sections or multi-segment structure, can rotate respectively, and described rear end inner key cylinder connects the transmission of dead bolt finger.When running into unconventional unblanking, by lockhole being applied a revolving force, can make leading portion inner key cylinder and exterior key cylinder produce the certain displacement amount, but the rear end inner key cylinder there is not Influence of Displacement, stir the pellet shot from a slingshot of rear end inner key cylinder with instrument after, on, following pellet shot from a slingshot still rebounds in the internal cylinder pellet shot from a slingshot hole, if stretch into inner key cylinder front and back section inner key cylinder is applied a revolving force together, because the slit is very little in the keyhole, there is not the space tool using to stir pellet shot from a slingshot, the utility model is simple in structure, be easy to processing, good reliability has been avoided lockhole is applied a revolving force, make inner key cylinder and exterior key cylinder produce the certain displacement amount, re-use instrument such as steel wire and stretch into the unconventional mode of unblanking that inner key cylinder is stirred pellet shot from a slingshot.
Description of drawings:
Fig. 1 is the side-looking structural representation of a kind of flexible lock inner key cylinder of the utility model.
Fig. 2 is a kind of flexible lock inner key cylinder segmentation place schematic cross-section of the utility model.
The specific embodiment:
According to shown in Figure 1, the inner key cylinder of a kind of flexible lock of the utility model is a two-stage structure 1,2, can rotate respectively, and described rear end inner key cylinder 2 connects the transmission of dead bolt finger.
According to shown in Figure 2, after a kind of flexible lock of the utility model is rotated for fear of the leading portion lock core, uneven or the two-phase lock hole anisotropy of lockhole, use key can't insert the phenomenon that maybe can't open, a spacing ball 3 and one corresponding groove 4 with it can be set on the connection end face of front and back internal cylinder 1,2, and the central angle of described groove 4 is not more than 45 degree, makes when the leading portion inner key cylinder is rotated by external force, rotation amplitude is not more than 45 degree, and 45 degree effects are best.Make the front and back end inner key cylinder displacement longitudinally all be arranged because ball can vertically form tension force to inner key cylinder when turning to the groove limit, make things convenient for pellet shot from a slingshot to be stuck with respect to exterior key cylinder.Also play antitheft effect.
A kind of flexible lock of the utility model can be provided with neck pellet shot from a slingshot up and down in lock core, when unconventional unblanking and to behind revolving force of inner key cylinder, form a displacement between inner core and the outer core, when scratching out the pellet shot from a slingshot of stirring inner core with steel wire, the neck of neck pellet shot from a slingshot up and down is stuck easily, if the head of the neck pellet shot from a slingshot of inner key cylinder is a triangular structure, neck is stuck its head with regard to being easy to enter exterior key cylinder so, has improved antitheft effect.
Claims (4)
1, a kind of flexible lock is to be made of inner key cylinder, exterior key cylinder, lock body, dead bolt etc., it is characterized in that described inner key cylinder is a two-stage structure, can rotate respectively, and described rear end inner key cylinder connects the transmission of dead bolt finger.
2, according to the described a kind of flexible lock of claim 1, it is characterized in that on the connection end face of front and back internal cylinder, being provided with a ball and one corresponding groove with it, the central angle of described groove is less than 45 degree.
