However, the button and the lock tongue of the product and the like are less in integral structural design, so that the production, assembly, installation and use are inconvenient, the structural design is complex, and the production cost is high.

Disclosure of Invention

In order to overcome the defects, the utility model aims to provide a handle lock for the field, which solves the technical problems that the button and the spring bolt structure design in the prior similar products are not good enough to cause inconvenient production, assembly, installation and use and the button and the spring bolt adopt an integrated structure design less. The purpose is realized by the following technical scheme.

A handle lock is characterized in that an inner handle is arranged in an outer handle of the handle lock, and an installation hole is formed in the end face of one end of the outer handle; the inner handle is L-shaped, the inner handle is arranged in an inner corner groove of an outer handle mounting end, the corner of the inner handle is fixed at the corner end of the inner corner groove of the outer handle through a pin, one end of the inner handle extends out of the end face of an inner side notch of the outer handle, a lock tongue at the other end of the inner handle extends out of a door plate hole of the mounting position of the outer handle, an open groove for swinging the inner handle outwards is formed in the outer side of the mounting end of the outer handle, a spring is arranged between the outer handle and the inner handle in the open groove, and a lock groove is formed in one side of the open groove at the lock tongue position of the inner handle. Therefore, the handle lock integrates the button and the spring bolt structure in the existing similar products into a whole in the inner handle, and the functions of the button and the spring bolt can be realized by adopting one inner handle part.

The inner side of the inner handle in the inner corner groove of the outer handle is provided with a first limiting bulge, the outer corners of the outer handle are provided with second limiting bulges, and the first limiting bulge and the second limiting bulge of the inner handle are respectively abutted against the inner wall of the inner corner groove of the outer handle. The structure further improves the limit between the inner handle and the outer handle when the inner handle is operated.

The outer handle is characterized in that a second limiting bulge of the inner handle is arranged at the opening groove of the outer handle, and the outer side surface of the second limiting bulge of the inner handle is flush with and sealed with the groove opening of the opening groove. Thereby facilitating the dust prevention in the handle lock and the pick prevention of the side.

The outer handle is in a shape like a Chinese character [, and the end face of the other end of the outer handle is provided with the mounting hole. The above is an example of a form construction.

The outer handle is L-shaped, and the outer handle is an embodiment of another appearance structure.

And a spring between the inner handle and the outer handle is omitted, and a torsional spring is arranged between the inner handle and the outer handle at the pin. The structural embodiment of the torsion spring instead of the spring is described above.

The utility model has reasonable structural design, convenient production, assembly, installation and use, low production cost and good sealing performance; it is fit for using as the handle and the handle lock of cabinet to and the institutional advancement of like product.
