Abstract
A mechanical lock cylinder capable of preventing technical unlocking comprises a lock body device, a lock cylinder device and a key. The lock body device and the lock cylinder device are installed in a combined mode to form a lock head, a spring mechanism is arranged in the lock body device and the lock cylinder device in a matched mode, and the key is inserted into the lock cylinder device to trigger the spring mechanisms to unlock a lock. The spring mechanism is a double-spring mechanism which combines lock body springs with lock cylinder springs together and comprises a set of large spring mechanism bodies matched with the key and a set of small spring mechanism bodies which are arranged in large springs and matched with the key; the large spring mechanism bodies are matched with the key in a face contacting mode, and the contact faces are hook faces; the small spring mechanism bodies are matched with the key in a point contacting mode, and the contact points are hole grooves. The mechanical lock cylinder has the advantages that a curve spring lock structure and a common spring lock structure are combined, the antitheft capacity is high, the relative structure is simple, the economic cost is low, and technical unlocking and a master key can be effectively prevented.
Description
Technical field
The invention belongs to lockset apparatus field, particularly relate to a kind of mechanical lock structure of anti-technology unlocking.
Background technology
Existing cylinder lock is of a great variety, but common cylinder lock is unblanked by single key distribution type, and anti-theft capability is poor, and technology unlocking and master key problem emerge in an endless stream.Although can increase anti-theft capability by the degree of depth of superposition marble amount and pellet card master, its structure cannot keep out existing technology unlocking and master key is unblanked, easy stolen lock.On the basis of cylinder lock development, now invention has a kind of cylinder lock of large billiard mechanism, pellet face and key groove distribution type is utilized to unblank when unblanking, by increasing the complexity of pellet curved surface, its anti-theft capability is higher than common spring lock, but this lock also cannot keep out technology unlocking, just unlocking difficulty improves.
In order to anti-technology unlocking and master key, superior automobile or security door adopt very complicated lock core structure usually, improve input cost accordingly, not only bother but also expensive.The work of the applicant's long campaigns lock core tectonic sieving, understand very dark to the anti-theft capability of lockset, how can design a kind of structure is not very complicated lock cylinder structure, can be effectively antitheft, reach anti-technology unlocking and the master key of real meaning, reduce lockset input cost again simultaneously, common superior automobile or security door can be suitable for.
Summary of the invention
The object of the invention is the problem in order to solve the anti-technology unlocking of common common cylinder lock and master key ability, a kind of mechanical lock combining the anti-technology unlocking of curve list and common spring antitheft structure feature is provided, solves the problem of technology unlocking and master key from technical difficulty.
To achieve these goals, the technical solution adopted in the present invention is the mode large for existing curve lock cylinder technology combined with common little lock cylinder technology, arranges little pellet structure in the large pellet of curve.When unblanking, must when pellet curved surface and little marble hole groove all mate greatly, lock core just can be activated, and technology unlocking and master key all cannot solve obstruction when both exists simultaneously simultaneously.
