Description

Technical Field

[0001] This utility model relates to locks, specifically cabinet locks. Background Technology

[0002] One existing cabinet lock has lugs on both the lock seat and the handle. After aligning the two lugs, a padlock is inserted to lock the handle, as disclosed in application number CN 202322691098.7. During packaging and transportation, the lock seat is installed on the cabinet, but the handle is not attached to the lock seat. However, the lugs on the lock seat are fixed and protrude significantly from the outer end face of the lock seat, requiring larger cardboard boxes for transportation.

[0003] In addition, the handle lugs on the handle are also integrally molded on the handle. Since the two lugs block each other, the direction of use of the handle (the direction of opening and closing the lock) is singular and fixed. If the handle of the lock needs to change the operating direction, a separate lock needs to be designed, which is inconvenient to use. Utility Model Content

[0004] The purpose of this invention is to overcome the defects of the existing technology and provide a lock base for a cabinet lock that is easy to package.

[0005] To achieve the above objectives, the present invention provides the following technical solution: A lock base for a cabinet lock includes a lock base body and a plate-shaped lock base lug on the outer end face of the lock base body.
