Abstract

The invention relates to a double locking-disk type three-way mechanical cipher lock. The cipher lock mainly comprises a turnplate type cipher lock, a spoon type anti-theft lock, a three-way driving wheel, a driving gear, a rack unlocking mechanism, driven shaft mechanisms, a guide sleeve, a latch, a return spring, a rotary handle and the like, wherein the rotary handle is connected with the three-way driving wheel and the driving gear; the three-way driving wheel and the driving gear are fixed opposite to each other and can rotate homodromously; the three-way driving wheel drives the driven shaft mechanisms at the upper and lower ends and on the left side to move so as to make the latch stretch in the vertical direction and the horizontal direction, so that the three-way driving wheel has a three-way closing / opening function; the driving gear drives the rack unlocking mechanism to move leftwards and rightwards in the horizontal direction; and when one of the turnplate type cipher lock and the spoon type anti-theft lock is not opened, the rack unlocking mechanism cannot slide, the rotary handle cannot rotate, and the turnplate type cipher lock and the spoon type anti-theft lock are mutually independent. The cipher lock has the advantages of simple mechanism, reliable lock, easy manufacture, low production cost, high production efficiency and high product percent of pass.

Description

technical field [0001] The invention relates to a coded lock, in particular to a mechanical coded door lock. Background technique [0002] There are various types of mechanical combination locks on the market, and they are widely used in many places such as safes, file cabinets, safe doors, bank doors, warehouse doors, etc. The mechanical code lock generally only has one password, which is easy to be cracked, and only one-way locking in the horizontal direction of the door lock side, the locking direction is single, the internal transmission is unstable, and it is easy to be destroyed; that is, there is only one The locking method and the locking direction are limited to one side only. Contents of the invention [0003] The object of the present invention is to provide a combination lock, which can lock the safe door in multiple directions except the hinge side. [0004] The specific technical scheme is as follows: [0005] A coded lock, comprising a coded lock (1) and ...
