Cam type permanent magnet digital marble mechanical combination lock

Abstract

The invention relates to a cam type permanent magnet digital marbles mechanical combination lock which comprises a copper lock core, a copper lock tongue, a steel plate, M steel digital cam disks (M is greater than 2 and smaller than 20), a set of permanent magnet marbles and a set of permanent magnet codeless marbles. N characters are engraved on an outer cylindrical surface of the steel digital cam disks, and N equally divided and corresponding cams are arranged on an inner cylindrical surface (N is greater than 10 and is smaller than 100), N dislocations form in the interval between the permanent magnet digital marbles and the permanent magnet codeless marbles under the transformation of the cams; when the interval aligns with the interval between the lock core and the lock tongue, the lock tongue thread slides backward under an upward starting force of an unlocking wheel thread shaft, otherwise the lock tongue can not slide. The cam type permanent magnet digital marbles mechanical combination lock has the beneficial effects that: production material range is wide, production cost is low due to few parts, quantity of password is large and the password possesses Mth power of N; moreover, no hand feel and no sound are produced during unlocking, so that professional unlocking can be effectively avoided, therefore a security coefficient is high, and the cam type permanent magnet digital marbles mechanical combination lock is applicable to needs in various occasions.

Description

technical field [0001] The invention relates to a combination lock, in particular to a cam type permanent magnet digital list mechanical combination lock. Background technique [0002] Locks in the prior art have multiple forms, and the prior art generally uses a kind of pin lock with a key (such as figure 1 As shown), this kind of lock needs to use a key to open the lock. The lock is equipped with a lock core, a lock core pin, a lock body pin, a spring, a metal cover, a lock tongue, a lock bow, a lock body, and a key. The key is inserted into the lock core The radius of the pin of the lock core is equal to that of the lock core under the cooperation of the key teeth, so that the key can turn the lock core. The rotating lock core cooperates with the lock tongue to make the lock bow pop out under the action of the spring, so as to achieve the purpose of unlocking. The lock only needs to pry open the metal cover of the pin and take away the lock body pin, lock core pin and s...

AI Technical Summary

Problems solved by technology

The lock only needs to pry open the metal cover of the pin and take away the lock body pin, lock core pin and spring to achieve the purpose of unlocking. In addition, the lock can use a comb-shaped master key to forcibly connect the lock core pin with the lock core cylindrical surface. Cutting can also achieve the purpose of opening the lock, and the lock is easy to lose the key and cause potential safety hazards

In order to solve this problem, the Golden Dot Atomic Lock uses a patented lock that is anti-violence-proof with a master key. The lock uses a key that is inserted longitudinally from the cylinder of the lock cylinder, so that the vertical cylinder of the cylinder perpendicular to the inner cylinder of the key With the vertical movement of the key tooth surface, each vertical lock core pin has a different rotating groove. With the cooperation of the key tooth surface, the vertical movement makes it align with the horizontal lock core pin, and the horizontal lock core pin Under the action of spring force, it will be tangent to the outer cylinder of the lock core, so as to achieve the purpose of unlocking, but there are still defects that the key is not safe
