Loose-leaf notebook anti-theft coded lock based on synchronous belt drive

Abstract

The invention belongs to the technical field of loose-leaf notebook coded locks, and particularly relates to a loose-leaf notebook anti-theft coded lock based on synchronous belt drive. The loose-leafnotebook anti-theft coded lock based on synchronous belt drive comprises a U-shaped fixing plate, a lower fixing plate, a lock mechanism, a baffle, an upper fixing plate and the like, wherein the upper fixing plate and the lower fixing plate are connected through the U-shaped fixing plate; and an anti-theft groove is formed in the end, far away from the U-shaped fixing plate, of the side face ofthe lower fixing plate. The effect of connecting the upper fixing plate and the lower fixing plate through the U-shaped fixing plate is to facilitate installation of a loose leaf and a lock mechanismof a notebook; and the effect of forming the anti-theft groove in the end, far away from the U-shaped fixing plate, of the side face of the lower fixing plate is to be matched with an anti-theft stripon a first protection shell, and therefore when someone wants to steal secrets between the upper fixing plate and the lower fixing plate, gaps between the lock mechanism is shielded by the anti-theftstrip, a tool is isolated to the outer side of the lock mechanism through the anti-theft strip, and the aim of enabling stealing of the secrets in the notebook to be very difficult is achieved.

Description

technical field [0001] The invention belongs to the technical field of combination locks for loose-leaf notebooks, in particular to an anti-theft combination lock for loose-leaf notebooks driven by a synchronous belt. Background technique [0002] At present, most of the existing loose-leaf notebooks use motor-driven switches to open or close, and most of them use traditional digital combination locks. If the combination lock forgets the password, if you want to open the loose-leaf notebook, there is no professional staff present, and at the same time, you are in a hurry. When opening, it is necessary to destroy the combination lock to achieve the purpose of opening the combination lock; at the same time, the locking mechanism of the existing combination lock is simple, and it needs to consume a lot of electric energy when opening or closing. In order to achieve the purpose of saving electric energy, it is necessary to Design an anti-theft combination lock for loose-leaf not...
