CABINET LOCK FOR PLATES OF DIFFERENT THICKNESSES

A cabinet lock is disclosed. The cabinet lock includes an outer lock, an extension rod and an inner lock. The outer lock and the inner lock are separately disposed in two sides of the plate. The outer lock includes an outer decorating housing, a lock head and a lock post. The extension rod can optionally connect with the lock post and extend along an axis of the lock post. The inner lock includes an inner decorating housing, a lock barrel and a bolt. The lock post can optionally connect with the lock barrel through the extension rod. The lock head drives the lock post and the lock barrel for a telescopic movement of the bolt.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

Please refer toFIG. 1, it depicts an application schematic view of a cabinet lock for plates of different thicknesses of the present invention. The present invention provides a cabinet lock1for different thicknesses installed in a plate2. The plate2has a first plate surface2′ and a second plate surface2″ opposite to the first plate surface The cabinet lock1includes an outer lock10, an extension rod20and an inner lock30. The outer lock10and the inner lock30are disposed on two sides of the plate2respectively, and the extension rod20is disposed between the outer lock10and the inner lock30.

With referring toFIG. 2toFIG. 4, they depict a perspective exploded view of an outer lock and an extension rod, an assembly schematic view of an outer lock and an extension rod and an outer lock and an extension rod of the present invention. The outer lock10includes an outer decorating housing11fixed on the first plate surface2′, a lock head12disposed and inserted in the outer decorating housing11and a lock post13connected with the lock head12. In an embodiment of the present invention, the outer decorating housing11has a fastening hole110, and the lock head12is disposed corresponding to the position of the fastening hole110. Moreover, the outer lock10further includes a combination lock14, and the combination lock14is disposed in a lateral side of the lock head12.

The extension rod20is optionally connected with the lock post13and extended along an axis of the lock post13. In the present invention, the lock post13is a polygon column. One end of the extension rod20has a polygon hole200correspondingly, and the extension rod20is sleeved on the lock post13. More particularly, the extension rod20has a head section21having the polygon hole200and an inserting section22extended from the head section21. Preferably, the inserting section22is a polygon column for preventing it from rotational sliding.

The inner lock30includes an inner decorating housing31fixed on the second plate surface2″ of the plate2, a lock barrel32disposed and inserted in the inner decorating housing31and a bolt33disposed in a lateral side of the lock barrel32. In an embodiment of the present invention, the lock barrel32has a slot320, and the lock post13is inserted in the slot320through the extension rod20.

As shown inFIG. 4, the lock post13is optionally connected with the lock barrel32through the extension rod20. The lock head12drives the lock post13and the lock barrel32for a telescopic movement of the bolt33. That is the lock post13can directly connect and drive the lock barrel32for a telescopic movement of the bolt33.

In the present invention, the thickness H1 of the plate2and the thickness B of the inner decorating housing31are not limited and which can be adjusted by demands.

Please further referring toFIG. 5, it depicts an application schematic view of a cabinet lock for plates of different thicknesses of another embodiment of the present invention. The structure of the cabinet lock1in this shown embodiment is the same as the first embodiment. This embodiment differs from the first embodiment in the thickness of the plate2. In theFIG. 5, the thickness H2 of the plate2is thinner than the thickness H1 of the plate2. One end of the extension rod20is sleeved on the lock post13and the other end is inserted in a deeper location of the slot320.

In theFIG. 4andFIG. 5of the present invention, the lock post13of the cabinet lock1is connected with the extension rod20for adjusting the overall thickness of the cabinet lock1in a lock1of different thicknesses of the plate2.

Please also refers toFIG. 6, it depicts an application schematic view of a cabinet lock for plates of different thicknesses of further another embodiment of the present invention. The cabinet lock1of this embodiment differs from the first embodiment in the thickness H3 of the plate2. Another difference is that the cabinet lock1does not have the extension rod20. In the embodiment shown inFIG. 6, the lock post13of the cabinet lock1is directly inserted in the slot320.

In theFIG. 6of the present invention, the lock post13of the cabinet lock1does not connect with the extension rod20. The lock post13of the cabinet lock1is directly inserted on the lock barrel32for the cabinet lock1installed in a thinner plate2.
