Summary of the invention

The purpose of this utility model: in order to overcome the defect of prior art, the utility model provides a kind of case and bag puzzle lock for zipper, and its password of conveniently resetting is easy to use, simple to operate.

The technical solution of the utility model: a kind of case and bag puzzle lock for zipper, include housing, latch hook mechanism, cipher lock mechanism, lock core assembly and password reset mechanism, housing is provided with the lockhole inserted for slider of zipper fastener, latch hook mechanism includes corresponding lockhole position and is arranged on the latch hook body in housing, for driving the latch hook body to the actuator that departs from lockhole one lateral movement and for ejecting the first return unit of slider of zipper fastener, cipher lock mechanism includes locating shaft, cipher wheel, cam ring, described cipher wheel and cam ring are linked, cipher wheel, cam ring all is set on locating shaft, outside the sheathed cam ring of cipher wheel, the lock core assembly includes plug body, driving member, be axially arranged with slotted eye along locating shaft on driving member, driving member and plug body are linked, the locating shaft sidewall is provided with some convex tendons, cam ring is provided with the jack be complementary with convex tendon, also be provided with the second return unit for the cam ring that resets on described locating shaft, it is characterized in that: described password reset mechanism includes for promoting the impeller of cam ring along the axial slippage to the inside of locating shaft, be provided with the retaining part in described housing, the retaining part, at least one of them is elastic body to impeller, described retaining part is provided with for stoping the retaining projection of impeller along the axial slippage laterally of locating shaft.

Adopt technique scheme, when needs replacement password, by impeller by cam ring along axially slippage to the inside of locating shaft, now, cam ring separates with cipher wheel, can carry out the password replacement, the retaining projection arranged can stop impeller along axially slippage laterally of locating shaft, so just do not need to promote impeller always, after the replacement password completes, impeller axially can be promoted to overcome the retaining power of retaining projection laterally along locating shaft, make cam ring, impeller resets, also can pass through actuator, through driving member, the second return unit overcomes the retaining power of retaining projection, make cam ring, impeller resets, therefore, the case and bag puzzle lock for zipper of this structure, its password of conveniently resetting, easy to use, simple to operate.

Further setting of the present utility model: on described impeller, corresponding retaining raised position is provided with spacing preiection, and described retaining projection, spacing preiection all are circular-arc setting.

Adopt above-mentioned further setting, the spacing preiection of setting, so only need spacing preiection to coordinate and get final product with the retaining projection, thereby can dwindle the moving displacement of impeller, and then dwindle the volume of puzzle lock for zipper; Circular-arc retaining projection, spacing preiection can reduce mutual wearing and tearing between the two, long service life.

Further setting more of the present utility model: described retaining part is elastic body, and described retaining part and housing are wholely set.

Adopt above-mentioned further setting again, the retaining part set-up mode of this structure, easy to process, cost is low.

Further setting of the present utility model: described impeller one end extends on the lateral surface of housing.

Adopt above-mentioned further setting again, can conveniently be operated impeller, use convenient.
