Inner and outer clutch reversible lock body

Abstract

The invention discloses an inner and outer clutch reversible lock body. The lock body comprises a box body and a dual clutch assembly which is internally arranged between a box cover and a box bottom,wherein mounting holes are formed in the same positions of the box cover and the box bottom; two clutches of the dual clutch assembly are detachably connected with two independently-rotating shiftingblocks correspondingly; a handle drives the clutch connected with the shifting block to rotate synchronously through the condition that a shifting rod penetrates through the corresponding mounting hole to be inserted into the corresponding shifting block to rotate, and the effect that the two clutches in the dual clutch assembly are rotated with relative displacement is achieved; the two clutchesare engaged with latch bolt shifting pieces through third protrusions on the outer surfaces of the clutches, and the clutches drive the latch bolt shifting pieces engaged with the clutches to rotatesynchronously; and the extension ends of the latch bolt shifting pieces are engaged into bolt grooves in the tail ends of latch bolts, and the latch bolt shifting pieces drive the latch bolts to extend out or retract into the box body along with rotation of the corresponding clutches. The lock body is simple in structure, conversion of the door opening direction and independent rotation of the inner handle and the outer handle are achieved, and thus the flexibility of the lock body is improved.
