Abstract
The invention relates to an unlocking key of a mechanical digital lock. The variable-code key with cylinder shifting teeth is characterized in that: a key rod is provided with multiple shifting tooth holes; the cylinder shifting teeth are mounted in partial or all shifting tooth holes, freely stretch/withdraw relative to the shifting tooth holes, and can switch in different shifting tooth holes; and only one cylinder shifting tooth can be mounted in the shifting tooth holes on the same circumference of the key rod. With a simple structure, the variable-code key provided by the invention not only realizes the intrinsic locking/unlocking function of a key, but also can change the combination of the cylinder shifting teeth and the shifting tooth holes on different positions of the key; and moreover, a novel key component integrating the encryption function and the key locking/unlocking function is created, two simple and convenient cylinder shifting tooth structures are provided, and more other cylinder shifting teeth with the same concept are also applicable. The variable-code key is simple to operate, convenient to use and high in security and suitable to be matched with the concealed digital locks of various safety boxes and security doors.
Description
Technical field
The present invention relates to the key of unblanking of mechanical type digital lock.
Background technology
Traditional mechanical type digital lock exists many critical defects, for example: 1, do not have light not operate; 2, built-in combination padlock exists linkage and easily steals survey password position or damage lock inner member; 3, the digital disk of external combination padlock very easily destroys; 4, establishing close amount low technical opens easily; 5, reset password difficulty etc.Chinese patent 200820218876.3 provides can change password, establish the large mechanical type digital lock of close amount, but it needs that also supporting key is arranged accordingly, wherein spring key only has the open locking function, reliable when how to guarantee to use, and realize that key establishes closely without any enlightenment, still remain further research.
Summary of the invention
Deficiency in view of prior art exists the invention provides a kind of marble dialing tooth variable-code key, and billiards structure is ingenious, and realization is good fit with key bar, when realizing the open locking function, can utilize key to carry out cryptographic transformation.
The present invention realizes that the technical scheme that above-mentioned purpose adopts is: marble dialing tooth variable-code key, key bar is provided with several moving tooth holes, partly or entirely in the moving tooth hole cylinder shifting teeth is installed, the relative moving tooth of cylinder shifting teeth hole free-extension, cylinder shifting teeth can replace in different moving teeth hole, but in the moving tooth hole on the same circumference cylinder shifting teeth can only be installed on the key bar.
Press setpoint distance (setpoint distance can be not equidistant or equidistant, as long as corresponding with the digital disk position) and different angles on the described key bar and be provided with several moving tooth holes.
Blind hole or through hole are adopted in described moving tooth hole.
Described cylinder shifting teeth adopts the thin board type structure, two angles of thin plate struck side are made as fillet, the thin plate center offers guide runner, guide runner both sides spring stopper slot, the guide runner bottom is communicated with the spring fitting otch, and back-moving spring adopts two ends with the spring of spring arm, and back-moving spring is installed in the guide runner and spring arm places in the spring stopper slot of both sides, spring center hole interpolation dress alignment pin, alignment pin is installed on the key bar.
Described cylinder shifting teeth adopts box-frame formula structure, and moving tooth and back-moving spring are installed in the box-frame, and back-moving spring touches mutually with the moving tooth that relative box-frame slides, and box-frame is flexible relatively under the driving of back-moving spring for moving tooth, and telescopic section is the circular arc struck side.
Described moving tooth adopts the thin plate with spring groove.
Variable-code key of the present invention is simple in structure, not only realized the open locking function that key is intrinsic, and by the cylinder shifting teeth to key moving tooth hole and cooperation thereof, can the conversion cylinder shifting teeth and the moving tooth hole in the on the key combination setting of diverse location, it has been initiated and has established the brand-new key parts that close function and key open and close lock function are integrated in one, the cylinder shifting teeth structure of two kinds of features simple structure is provided, and the cylinder shifting teeth of other how same designs also can adopt.It has characteristic simple to operation, easy to use, that fail-safe is high, and the invisible digital lock that is best suited on all kinds of safety cabinets and the various security door supports the use.
