Summary of the invention

The purpose of this utility model is to be exactly on the basis of original 200520089803.5 key permutation lock patents, further carries out technological improvement, provide a kind of structure more rationally, good looking appearance, the flexible key permutation lock of lock-opening closing mechanism.

The purpose of this utility model is to realize like this, key permutation lock comprises: bolt plate, the lock end, spring, upper and lower posting, button, slide bar, unlock key and locking closure, slide bar is arranged on the side at the lock end, in the opening from the lock end of the dead bolt in bolt plate, pass and hang on slide bar, several buttons are arranged at lock the end, the boss on two sides exposes respectively from lock the perforate at the end and the opening on locking closure, the locking closure that is provided with lock cap is fastened at lock the end, it is characterized in that: on the inner surface at the lock end, be provided with upper and lower locating piece, upper and lower posting is installed on respectively in upper and lower locating piece, cross section is the middle part that leg-of-mutton driving lever is arranged on slide bar, spring fitting is between the stile and draw-in groove of driving lever, on the inner surface at the lock end, be provided with two alignment pins, utilize the pin-and-hole of one end to hang on alignment pin with the unlock key of button, other end contacts with the inclined-plane on driving lever, in the button hole of button from locking closure, pass.

Compared with prior art, the utility model has retained the feature that original lockset is lightweight, lock body is thin, simple in structure, easy to use, but partial structurtes design is more reasonable, unlock key is arranged on the middle part of lock body, can make to unblank, lock and be convenient, profile is perfect coordination more, and mechanical operation is more flexible; Especially be applicable to very much using on the higher implements of the frequencies of utilization such as diary, file, writing case.
