Detailed description of the invention
See Fig. 1-Fig. 6, the utility model relates to the positive and negative idle-run lamina lock core of a kind of super B level, comprise lock housing 1, middle cover 2 and lock gall 3, described lock gall is arranged in described middle cover, the external diameter of described lock gall and the diameter compatible of described middle cover close, be set in described lock housing in described, the external diameter of described middle cover and the diameter compatible of described lock housing close, one end end face of described lock gall offers key insert port, several blade cavities 31 are offered in described lock gall, blade cavity described in several is communicated with described key insert port, at least one blade 4 is equipped with in each described blade cavity, a shifting block 41 is provided with in the cavity of each described blade, described shifting block is positioned at the upper left quarter (see Fig. 3) of the cavity of its correspondence, upper right quarter (see Fig. 5), lower left quarter (see Fig. 4) or right lower quadrant (see Fig. 6).
Here it should be noted that, after inserting blade in blade cavity, all cavity formations are communicated with key insert port and form keyhole.
Because each blade is provided with a shifting block, and shifting block can be arranged on the upper left quarter of cavity, upper right quarter, lower left quarter or right lower quadrant, after the combination of several blades, the position of shifting block some up some in below, when unauthorized person opens this lock, the shifting block of top and the shifting block of below need be stirred simultaneously, and just lock can be opened after driving corresponding blade to arrive corresponding position, because the shifting block will stirring both sides adds the difficulty of unblanking simultaneously, not easy to operate, in addition, because keyhole is relatively limited, and stir the shifting block of both sides simultaneously, need two steel bars to stir simultaneously, and it is comparatively difficult two steel bars to be inserted keyhole simultaneously, even if, two steel bars are inserted keyhole, because two steel bars are by the space hold in keyhole, it stirs shifting block will be more difficult, thus enhance its theftproof performance.
Preferably, two shifting blocks of two blades of arbitrary neighborhood are respectively in the upper and lower of its each self-corresponding cavity.
