Description

Technical Field

[0001] The utility model belongs to the technical field of locks, and in particular relates to a handle-hidden lock. Background Art

[0002] At present, the locks available on the market generally include a lock case, a cover plate, a handle inserted into the lock case, and a rotating block concentrically assembled with the handle. The lock case and the cover plate are detachably connected by a plurality of first screws, the handle and the rotating block can rotate relative to the lock case, and the handle is equipped with a reset torsion spring. An inner core passing through the cover plate is concentrically movably provided on the rotating block, and pins passing through the rotating block are movably provided on the upper and lower parts of the rotating block. The rotating block of this lock is manufactured in one piece, and the pin installation process is relatively cumbersome and the structure is complex, resulting in a higher thickness of the rotating block, which in turn increases the thickness of the lock case, increases the consumption of raw materials, and increases the cost.
