Above-mentioned lockset, Arming Assembly comprises pedestal and the insurance block that is installed in pedestal one side, and lock body is provided with a projection, and pedestal is provided with a retainer spring that is used and pedestal can be located with projection, have a breach on the pedestal, described operating portion places in the breach; The bottom of main dead bolt assembly be provided with one with the safety pole that is used of insurance block, after locking by interior handle, the insurance block be positioned at safety pole under, the insurance block stops main dead bolt assembly to move downward, and can't open the lock with the key; After unblanking by interior handle, the insurance block misplaces with safety pole, and moving downward of main dead bolt assembly is unrestricted.
Above-mentioned lockset, main dead bolt assembly have safety slide and with the safety slide sliding piece of its interlock, the outer end of safety slide sliding piece is provided with backstay, the described portion of locking is positioned between the backstay of the reference column of tongue switching sheet and safety slide sliding piece, one side of last lock section has cooperated the effect of locking with reference column, opposite side has cooperated the effect of opening safety slide with backstay, thereby handle can be unblanked in making.
Above-mentioned lockset, the edge formation one and the last lock section that reference column is used of outer shifting fork piece reach the purpose of locking by rotating outer handle.
Above-mentioned lockset respectively forms one and opens oblique tongue on the inside and outside shifting fork piece, be used to out oblique tongue.
The utility model drives moving of Arming Assembly by the rotation of interior handle, thereby finish main dead bolt assembly is insured, and can not open the lock with the key outdoor, has improved the safety when lockset uses.
The utility model is described in further detail below in conjunction with specification drawings and specific embodiments.
