Stacked mechanical combination lock

Abstract

A stacked code mechanical combination lock comprises a casing (30) having a rotational core base (1) installed therein. When the rotational core base (1) is rotated towards an unlocking direction, a latch bolt (12) is retracted via a transmission member. A center hole (2) is provided at the center of the rotational core base (1). Two or more code tracks (3) are provided at the rotational core base (1) around the center hole (2). The code tracks (3) communicate with both a front side and a rear side of the rotational core base (1), and are arranged in a radial configuration about a center axis of the center hole (2). Code plates (4) are installed in two or more of the code tracks (3). A middle section of each of the code plates (4) is hinged to the rotational core base (1). An outer protruding piece (5) is arranged at one end of each of the code plates (4) away from the center hole (2), and an inner protruding piece (6) is arranged at another end of each of the code plates (4) towards the center hole (2). A ring (7) is installed at the front side of the rotational core base (1). A dial pin (11) is arranged on the ring (7), and can drive the ring (7) to rotate in relation to the rotational core base (1).

Description

technical field [0001] The invention relates to a mechanical coded lock, in particular to a code-stacked mechanical coded lock. Background technique [0002] At present, combination locks are mainly divided into electronic combination locks and mechanical combination locks. Electronic combination locks are vulnerable to electromagnetic interference and software cracking, and have low reliability. Although the reliability of mechanical locks is relatively high, most of the coded components of the existing mechanical coded locks are independently set, which can be cracked one by one by technical means, and there is still a large hidden danger of technical opening. Contents of the invention [0003] The purpose of the present invention is to provide a code-stacked mechanical code lock, whose code components are stacked and locked after being locked, and can only be unlocked according to the code sequence, and a single code component cannot be technically opened, which can gre...
