Abstract

The utility model relates to an unlocking key for a mechanical digital lock, which discloses a marble dialing tooth variable-code key. The marble dialing tooth variable-code key is characterized in that a key rod is provided with a plurality of dialing tooth holes; parts or all dialing tooth holes are provided with marble dialing teeth; the marble dialing teeth freely extend relative to the dialing tooth holes and can change positions in different dialing tooth holes; but each dialing tooth hole on the same circumstance on the key rod only can be provided with one marble dialing tooth. The marble dialing tooth variable-code key disclosed by the utility model has a simple structure, the inherent locking and unlocking function of the key can be realized, and in addition, the combined arrangement of the marble dialing teeth and the dialing tooth holes on different positions of the key can be changed by changing the dialing tooth holes of the key and the marble dialing teeth matched with the dialing tooth holes. The unlocking key for the mechanical digital lock is an initiated brand-new key component which combines the functions of setting passwords, unlocking and locking, two marble dialing tooth structures with simple structure are provided, and the unlocking key for the mechanical digital lock is also suitable for more other marble dialing teeth with the same concept. The unlocking key for the mechanical digital lock has the characteristics of high security, is simple to operate, is convenient to use and is suitable to be matched with invisible digital locks on various safety boxes and antitheft doors.

Description

Pellet shot from a slingshot moving tooth variable code key

Technical field

The utility model relates to the key of unblanking of mechanical type digital lock.

Background technology

The traditional mechanical combination padlock exists many critical defects, for example: 1, do not have light not operate; 2, built-in combination padlock exists linkage and steals survey password position or destruction lock inner member easily; 3, the digital disk of external combination padlock very easily destroys; 4, establishing close amount low technical opens easily; 5, reset password difficulty or the like.The previous Chinese patent 200820218876.3 of applicant provides can change password, establish the big mechanical type digital lock of close amount; But it also needs supporting key accordingly; Wherein spring key has only the switching lock function; Reliable when how to guarantee to use, reach the realization key and establish the close enlightenment that has no, still remain further to be studied.

Summary of the invention

In view of the deficiency that prior art exists, the utility model provides a kind of pellet shot from a slingshot moving tooth variable code key, and billiards structure is ingenious, realizes and the good fit of key bar, when realizing opening and closing lock function, can utilize key to carry out cryptographic transformation.

The utility model realizes that the technical scheme that above-mentioned purpose adopted is: pellet shot from a slingshot moving tooth variable code key; Key bar is provided with several moving tooth holes; Partly or entirely in the moving tooth hole pellet shot from a slingshot moving tooth is installed; Freely stretch in the relative moving tooth of pellet shot from a slingshot moving tooth hole, the pellet shot from a slingshot moving tooth can replace in different moving teeth hole, but in the moving tooth hole on the same circumference pellet shot from a slingshot moving tooth can only be installed on the key bar.

Press setpoint distance (setpoint distance is equidistance or equidistance not, as long as corresponding with the digital disk position) and different angles on the said key bar and be provided with several moving tooth holes.

Blind hole or through hole are adopted in said moving tooth hole.

Said pellet shot from a slingshot moving tooth adopts the thin board type structure, and two angles of thin plate struck side are made as fillet, and the thin plate center offers guide runner; Guide runner both sides spring stopper slot; The guide runner bottom is communicated with spring otch is installed, and back-moving spring adopts two ends to have 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; Plug-in mounting alignment pin in the spring center hole, alignment pin is installed on the key bar.

Said pellet shot from a slingshot moving tooth adopts box-frame formula structure, and moving tooth and back-moving spring are installed in the box-frame, and back-moving spring touches with the moving tooth of box-frame slip relatively mutually, and moving tooth relative box-frame under the driving of back-moving spring is flexible, and telescopic section is the circular arc struck side.

Said moving tooth adopts the thin plate that has spring groove.

The utility model variable code Key structure is simple; Not only realized the switching lock function that key is intrinsic; And through to the pellet shot from a slingshot moving tooth of key moving tooth hole and cooperation thereof, can conversion pellet shot from a slingshot moving tooth and the moving tooth hole in the combination setting of diverse location on the key, 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 pellet shot from a slingshot moving tooth structure of two kinds of features simple structure is provided, and the pellet shot from a slingshot moving tooth of other more same designs also can adopt.It has characteristic simple to operation, easy to use, that fail-safe is high, is best suited for the supporting use of stealthy combination padlock on all kinds of safety cabinets and the various security door.

Five, the specific embodiment

Below in conjunction with accompanying drawing the utility model is done further explain, but the utility model is not limited to specific embodiment.

Embodiment 1

Like Fig. 1, the pellet shot from a slingshot moving tooth variable code key shown in 2, press setpoint distance (setpoint distance is equidistance or equidistance not, as long as corresponding with the digital disk position) and 90 degree, 45 degree, 180 degree, 30 degree, 90 degree and 45 degree on the columniform key bar 1 and be provided with 6 through-hole type moving tooth holes 2 (the moving tooth hole is like Fig. 6,7, shown in 8); Partly or entirely in the moving tooth hole pellet shot from a slingshot moving tooth 3 is installed; Freely stretch in pellet shot from a slingshot moving tooth 3 relative moving tooth holes 2, pellet shot from a slingshot moving tooth 3 can replace in different moving teeth hole, and wherein pellet shot from a slingshot moving tooth structure is like Fig. 3, shown in 4; Two angles of pellet shot from a slingshot moving tooth struck side thin plate are made as fillet; The thin plate center offers guide runner 5, guide runner both sides spring stopper slot 6, and guide runner 5 bottoms are communicated with spring otch 7 are installed; Back-moving spring 8 employing two ends have the spring of spring arm; Back-moving spring 8 is installed in the guide runner 5 and spring arm places in the both sides spring stopper slot 6, plug-in mounting alignment pin 4 in the spring center hole, and alignment pin is installed on the key bar 1.
