Shaftless connection variable combination encryption mechanical key
Technical field
The present invention relates to a kind of key combined, the variable combination encryption mechanical key of particularly a kind of shaftless connection.
Background technology
In recent years, many lockset manufacturers increasingly paid attention to the safety of lock and the research and development of anti-theft, such as machinery
Theftproof lock, electronic intelligence theftproof lock.But almost all of mechanical anti-theft lock is all equipped with the mechanical key of a set of emergency opening
Even if spoon is that is to say, that the theftproof performance of lockset is very high, as long as taking corresponding unlocking key, the peace of this lockset
Full performance is actually zero.This just brings a new problem, if avoiding mechanical key to go adrift or being replicated.Nowadays
Technological constraints under, the duplication of key is easy.Therefore it provides a mechanical key that cannot replicate for key loss or
The stolen potential safety hazard brought has very important significance.
The application for a patent for invention that applicant Yantai Sanhuan Technology Co., Ltd. submitted in 2014 2 months on the 19th, it is special
The entitled variable combination mechanical key of profit, Application No. 201410055233.1, announce and entered examination as to substance.This invention
Patent provides a kind of combined machine key, and concrete structure is the multiple spoons of type parts that can be formed spoon tooth by axle concatenation.Subsequently
Stage continues in R&D process, finds that the structure that axle connects has that structure is relative complex.Then think design one kind without axle
The combined ciphering key connecing.Therefore, in this application, it is directed to this technical research combinative structure of another kind of shaftless connection again.
Content of the invention
It is contemplated that the technological deficiency that the mechanical key being directed to various locks on current market is easily replicated, with
When combined axis connect key presence technical problem, and then provide a kind of reasonable in design, fundamentally realize anti-theft, anti-copying
Shaftless connection variable combination encryption mechanical key.
The present invention is achieved by the following technical solutions:
Shaftless connection variable combination encryption mechanical key, including the shank of the key, it is characterized in that described the shank of the key end
Releasable connection has spoon type part, described the shank of the key end and the phase being combined by several independent spoon type part sequentially grafting
It is to be realized by embedded connected structure that axial direction between adjacent spoon type part, between two adjacent spoon type parts connects, institute
The radial positioning stated between two spoon type parts between the shank of the key end and adjacent spoon type part, adjacent is by alignment pin
Realize;
A kind of scheme of described embedded connected structure: the described the shank of the key axially sequentially connecting and described spoon type part it
Between, and to be dovetail groove by carrying each other or forked tail platform between described adjacent spoon type part to realize embedded grafting
's;
Concrete structure is: the connecting end surface of described the shank of the key offers the dovetail groove with radial direction entry, mutually inserts therewith
The described spoon type part connecing is provided with and can insert along described radial direction entry and embed matching swallow in described dovetail groove
Tail platform;Likewise, the one of spoon type part connecting end surface being mutually inserted offers the dovetail groove with radial direction entry, separately
One spoon type part is provided with and radially entry can insert and embed in described dovetail groove and matching forked tail platform;Institute
State the dovetail key that alignment pin uses closure at the entry of described dovetail groove, described dovetail key is used for limiting described dovetail
Platform moving radially in described dovetail groove.
Another kind of scheme of described embedded connected structure: the described the shank of the key axially sequentially connecting and described spoon type part
Between, and be axial boss by carrying each other between described adjacent spoon type part or axial shrinkage pool is embedded to realize
Grafting;
Concrete structure is: is provided with axial boss in the middle part of the connecting end surface of described the shank of the key, the described spoon type plugging therewith
It is provided with the axial shrinkage pool that can house described axial boss in the middle part of the end face of part;Likewise, the one of spoon being mutually inserted
It is provided with axial boss in the middle part of type part connecting end surface, in the middle part of the end of another spoon of type part, be provided with that can to house described axial direction convex
The axial shrinkage pool of platform;Half-moon groove, the footpath of each spoon of type part are all offered on the axial boss of described each spoon of type part
All offer the dowel hole that can run through described axial shrinkage pool to side, being located by connecting between described spoon type part is logical
After be plugged in simultaneously the alignment pin within described dowel hole and half-moon groove realization;
Described spoon type at least includes two independent spoon type parts, and the design form of described spoon type part can be with angle
Become and turn to differential spoon type part or with height change for differential spoon type part.
The present invention is shaftless to connect variable combination encryption mechanical key, using the combining form of variable spoon type part, reaches and refuses
The function of unlocking absolutely, fundamentally achieves the purpose of key anti-theft, anti-copying, for comparing the spoon type part that axle connects, the application
Technical scheme ensure that by the embedded connected structure of spoon type part the axial direction between spoon type part connects and radially fixed simultaneously
Position, makes overall structure simpler and more direct, parts are more simplified, also enables identical function simultaneously.
