The utility model relates to a kind of lock group, especially relates to the lock group of using on a kind of refrigerator.

At present in the prior art, lock group as the refrigerator use, normally by lock core, lock core base, latch hook and lock nose are formed, wherein the key insertion end of lock core has a lock core cylindrical, lock core base comprises lock core base plane and lock core base cylinder, it in the lock core base cylinder lock core base hole, there are equally distributed four splines border, lock core base hole, and lock core is positioned at the lock core base hole, and a hook lock is arranged on the latch hook, hook lock is enclosed within the tail end of lock core, the lock group of this structure exists following defective, one, latch hook is positioned at the tail end of lock core, causes the lock assembling allotment of labor complexity of planting, the cost height, and latch hook is easily frozen by frost, influence is rotated, and simultaneously, easily causes damages such as latch hook during access food, two, purposes is few, is not suitable for using on the refrigerator of dark handle structure.

The purpose of this utility model is to overcome above-mentioned defective, provides a kind of technology simple, economical and practical latch hook external lock group.

The utility model is to realize like this, it is to improve on the prior art basis, comprise: a spline depression certain size, lock core cylindrical place is provided with the pin shape platform of a projection, a pin shape platform part is positioned at the lock core base hole, the hook lock of latch hook is enclosed within lock core cylindrical place, and has a depression and the pin shape platform of projection to be complementary on the hook lock;

The axial length of pin shape platform is near latch hook thickness and spline depression size sum, and the length of pin shape platform circumferencial direction is near the distance between two splines;

Two screwing through hole are arranged in order to the pin core print seat on the lock core base plane;

The lock core tail end is equipped with the opening ring washer;

The lock core base cylinder is positioned at a side on lock core base plane, and latch hook is positioned at the lock core base plane in opening;

There are two recessed rank both sides of the edge, lock core base plane, have an outer cover that matches with the lock core base plane to snap in the recessed rank by elastic claw;

Adopt the utility model, not only simple for assembly process, and realize that latch hook is external, be fit to multiple cabinet and use.

Below in conjunction with accompanying drawing the utility model is described further.
