Abstract

The utility model relates to a variable-camber planar code key designed according to the bionic principle. The variable-camber planar code key comprises a circular planar code dial, a clockwise outer spring, an anticlockwise inner spring, a traction steel wire and a rigid key handle. The key can not only change camber and enable a lock core of a matched lock to adopt the concealed design, but also adopt the combination with a planar code, thereby improving the technical theft opening difficulty, and simultaneously effectively reducing the probability of repeated codes.

Description

Variable camber plane sign indicating number key

Affiliated technical field

The utility model relates to a kind of mechanical lock variable camber plane sign indicating number key.

Background technology

At present, known mechanical lock key is by password tooth body and the shank of the key integral type rigid structures dimerous.Key is inserted corresponding mechanical lockhole, and the twisting key both can be opened lockset.But this architectural characteristic of key makes the lock core design of existing machinery lockset directly expose, thereby provides great convenience for technical pirate of the open just.In addition, because the password combination of existing key is a linear array, under the situation of key volume and length limited, its cipher code set resultant is limited, is easy to generate to overlap to open by mistake phenomenon, has reduced the safety of mechanical lock equally.

Summary of the invention

In order to overcome many deficiencies that the existing machinery lock key exists, the utility model provides a kind of variable camber plane sign indicating number key, and this key can not only make the lock core of mechanical lock hidden, increase the technology opening difficulty, and number of password is big, and it is extremely low that coincidence opens by mistake probability.

The technical scheme that the invention for solving the technical problem adopted is: variable camber plane sign indicating number key adopts bionics principle, is made up of rigidity the shank of the key five parts at suitable, counterclockwise two-man act, tractive steel wire and the rear portion at the circular flat combination disk of head, middle part.Supporting with it lockset, be provided with in the lock body wide-angle bending, inner level and smooth and with the rigid conduit of exterior, internal diameter of the pipeline is slightly larger than the outer spring external diameter of key.When variable camber plane sign indicating number key stretched into the lockset rigid conduit, the spring at circular flat combination disk and rear portion thereof can change with the camber of pipeline, and until the plane code-disc hidden lock core in the lockset that coincide, the rigidity the shank of the key of lockset inside and outside is stayed in twisting then; Because of spoon body spring is inside and outside double structure reverse design, under the acting in conjunction of external torsion and tube wall, can effectively torsion be delivered to the plane combination disk of head along the spring of bending, can effectively offset the deformation that single spring produces because of torsion again, make key more smooth and easy in operating process, built-in tractive steel wire plays the shop and helps traction action when key is extracted, prevent that inside and outside spring is influenced and sex change by pulling force.In addition, compare the linear array of password, the planar alignment combined amount of password is its how much multiples, and the probability of coincidence reduces greatly.

The beneficial effects of the utility model are

Can make lock core realize hidden design, not only greatly strengthen technical opening difficulty, and effectively improve the cipher code set resultant.Simple in structure, cost is low, and is easy to operate.
