Abstract

The utility model relates to a double-control double-lock antitheft coded lock which is an antitheft device and solves the defects of other techniques. The double-control double-lock antitheft coded lock is formed by connecting a mechanical lock and a common program-controlled lock, wherein the mechanical lock is sleeved by a primary lock core, a secondary lock core and a tertiary lock core by levels along the shaft diameter; a primary lock disc, a secondary lock disc and a tertiary lock disc are sleeved on the shaft diameter of the primary lock core; the middle parts of the primary lock disc, the secondary lock disc and the tertiary lock disc are respectively provided with circular holes corresponding to the primary lock core, the secondary lock core and the tertiary lock core; the periphery of each circular hole is provided with trough lines with different angles; the periphery of the lock disc is provided with lock sockets with different positions as well as a plurality of imaginary lock sockets simultaneously; a protective sleeve is sheathed outside the lock core, and a lock seat is sheathed outside the protective sleeve; a mechanical key is a rectangle, and two sides of the key are respectively provided with two toggle forks; one end of the key is provided with a rope hole and the other end thereof is a plug; and the program-controlled lock is a common electronic lock. The double-control double-lock antitheft coded lock has easy operation and good safe performance and is economic and durable.

Description

Two control twin-lock anti-theft puzzle locks

One, technical field:

The utility model relates to a kind of anti-theft device, especially two control twin-lock anti-theft puzzle locks.

Two, background technology:

Oil tank that present oil field is used and the lock on the casing, because backward in technique, theftproof performance is poor, and stolen phenomenon often takes place.

Three, summary of the invention:

The purpose of this utility model provides a kind of simple in structure, two control twin-lock anti-theft puzzle locks that theftproof performance is good, it has solved the shortcoming that other technology exists, the purpose of this utility model is to realize like this, it is to be formed by connecting by mechanical lock and general Program-controlled lock, mechanical lock is nested by the diameter of axle step by step by one-level lock core, secondary lock core and three grades of lock cores, is carved with password and password angle line respectively at an end of one-level lock core, secondary lock core and three grades of lock cores; At the center of one-level lock core cipher dish is groove shape keyhole; Two round key holes that symmetry is arranged on the circumference of secondary combination disk; Two round key holes that symmetry is arranged on the circumference of three grades of combination disk; On the one-level lock core diameter of axle, overlapping one-level, secondary and three grades of lock collars, the centre of one-level, secondary and three grades of lock collars and one-level lock core, secondary lock core and three grades of lock cores have corresponding circular hole respectively, in each circular the not equal angular line of rabbet joint is arranged, inequipotential lock socket is arranged on the circumference of lock collar, also have several illusion lock sockets simultaneously; Protective sleeve is enclosed within outside the lock core, and lock is enclosed within outside the protective sleeve; Mechanical key is a cuboid, stirs fork by two respectively in the both sides of key; One end of key has the rope hole, and the other end is a plug.Program-controlled lock is common electronic lock.

During work, carry out Program-controlled lock then after earlier mechanical lock being pinned, mechanical lock lock fork is pinned by Program-controlled lock; During unlatching, earlier good password is opened mechanical lock, open electronic lock, stir mechanical lock lock hand fork handle then, can open.

The utility model is easy to operate, and safety performance is good; Economy and durability.
