Multi-bar clamping groove lock

Abstract

The invention discloses a multi-bar clamping groove lock which comprises a shell, a key, a spring bolt and a latch. The multi-bar clamping groove lock is characterized by further comprising an open key shaft sleeve arranged in a key hole in the middle of the upper side of the shell, a plurality of sheet clamping bars arranged below the key shaft sleeve in the shell and perpendicular to the key shaft sleeve, sheet pull rods arranged among the clamping bars, and a comb-like top leaf spring arranged on the inner bottom face of the shell. The lock is reasonable in structure, small in number of components and convenient to install, and the processing property is highly optimized. After the toothed key is inserted into the key shaft sleeve, as an open groove of the key shaft sleeve has a guidance effect and the key shaft sleeve can rotate flexibly along with the key, unlocking is easy and convenient to achieve by rotating the key. In addition, the key point for unlocking is that circular arc clamps, with different radiuses, of the sheet clamping bars correspond to and are matched with multiple key teeth in tooth number and height, the higher the cardinal number of the match is, the higher the selectivity is correspondingly, and repetitiveness of the lock key is greatly reduced. The lock is simple in structure and mounting process, unlocking is convenient and smooth, and the lock has the effective antitheft property and is favorable to users.

Description

technical field [0001] The present invention relates to a mechanical lock, especially a tumbler lock and a blade lock. Background technique [0002] Existing mechanisms include tumbler locks and blade locks.
