Abstract
The utility model relates to a keystroke type mechanical cipher safety lock. Some of the existing homogeneous safety locks have complicated structure, and the ciphers of some of the existing homogeneous safety locks can be deciphered by the feeling of hands. In the lock of the utility model, a control plate which can be moved upwards and downwards is arranged in a lock shell, and a plurality of cipher pins provided with grooves are penetrated through the control plate. Frames on both ends of the cipher pins are arranged on a front and a back brackets on both sides of the control plate, and the front ends of the cipher pins are provided with keystrokes extending out of a front panel. When the control plate is moved to a lower position, a lock core which is clamped by the lower end of the control plate can not be rotated. When ciphers are pushed and keystrokes are pressed and the grooves on all cipher pins are aligned with each other, the control plate can be moved upwards along the grooves to enable the lock core to rotate to unlock the lock. A restoring device is also arranged in the lock shell. The utility model has the advantage of simple structure, and the ciphers are not easy to decipher by the feeling of hands.
Description
The utility model belongs to a kind of touch-tone mechanical cipher safety lock.
Mostly existing cipher lock is what circular dial scale was checked numbers, weak point is to be difficult under the dark situation of light sign indicating number, some improved button cipher locks can be with touching password under the dark situation of light, two kinds of this class lock branch electronic type and mechanical types, the former easily is damaged, the latter generally exists structure complicated, or the operation easy break-down, or can be with deficiencies such as feel break a code.
The utility model aims to provide a kind of simple in structure, and cost is low, good confidentiality, not troublesome button-type mechanical coded sign indicating number safety lock.
The technical scheme that realizes above-mentioned purpose is (referring to accompanying drawing 1 embodiment), this safety lock comprises lock housing (12), front panel (10), lock core body (1), can be controlled at the lock core (2) that rotates in the lock core body by key, what be fixed on that the lock core afterbody is used to stir unlocking mechanism dials bar (18), it is characterized in that, in lock housing, be provided with one parallel with front panel, can move up and down and move to lock core can be blocked when the next and make its control panel that can not rotate (7), be provided with fore-stock plate (5) between control panel and the front panel, and be provided with after-poppet plate (6) between the rear board, several code pins (11) are passed control panel with being slidingly matched, the code pins two ends put in the plate hole that the fore-stock plate that is positioned at the control panel both sides and after-poppet plate are opened with being slidingly matched respectively, code pins is provided with code groove (13), each code pins front end correspondence is provided with the code pins split, stretch out front panel and back-moving spring is housed, can promote the button (8) of code pins when moving backward, also be provided with in the lock housing and can all code pins be pushed away neat resetting means forward from afterbody.
The operating principle of this lock is, when control panel is in the alignment reset mode, code groove on some code pins faces the control panel bore edges, another part is then staggering with control panel on the direction of front panel, control panel rides on the outer circle wall of a part of code pins in back, the control panel lower end was blocked the pin core it can not be rotated this moment, was fixed in dialling bar and can't starting unlocking mechanism of lock core rear portion, and safety lock is in the password locking state.When with button with the code pins of groove and control panel dislocation to pusher, the groove of this part pin is alignd (institute is fluted at this moment all aligns with the control panel bore edges) with the control panel bore edges, this moment, control panel can move upward along the code pins groove, the lock core that originally was lockable can rotate under key control, makes the bar of dialling of its afterbody open unlocking mechanism.The code pins of above-mentioned groove dislocation promptly is to form password.After having turned on the key lock, with resetting means all code pins are pushed away together forward again and reset, give and locked insurance with password lock core is locked again this moment.
The utility model has the advantages that: intensity is good, not fragile, owing to press the feel difference of each button little, so overcome the deficiency that some safety locks easily break a code with feel, improved safety factor, and also easy to operate, also can be under the situation a little less than the light with touching to going out password, easy break-down is not simple in structure, and cost is low.

Embodiment 1 (seeing Fig. 1 to Fig. 3)
This routine lock core is located at the bottom of front panel 10, is provided with groove on lock housing inner cylinder lock core top, and control panel 7 lower ends parallel with front panel snap in the lock core groove, and it can not be rotated, and when control panel moved upward, lock core could rotate (referring to Fig. 3).
This example is provided with 4 row's 3 row code pins 11 and corresponding key 8,13 fens two kinds of positions of the code groove of establishing on it, a kind of is to aim at control panel plate hole edge under reset mode, another kind of then forwards to the control plate hole position of staggering, the equal correspondence of code pins 11 front ends is provided with extending panel, back-moving spring is housed, code pins can be pushed to back button 8 when direction pushes away in lock housing, when unblanking, push inward with the code pins of button by password dislocation, the groove of all code pins is all alignd with control panel, and can open lock this moment.
The concrete structure of this routine resetting means is, between after-poppet plate 6 and rear board, establish a restoring board that can move up and down 15, position facing to code pins on the plate is provided with reset hole 16, the code pins afterbody is designed to tapered slope, the reset hole edge leans against on the code pins rear portion tapered slope that is pushed to the position, back, also be provided with one simultaneously and pass front panel, the front supporting plate frame, control panel, the rear carrier plate frame, the control lever 4 that resets of rear board, the bore dia that passes the control lever that resets on control panel and the restoring board is all greater than the control lever diameter that resets, the control lever that resets restoring board can be made progress when being provided with at the position of passing restoring board and rotating jack-up ejector pin 17, when resetting control lever with knob 3 rotations that reset on the front panel, ejector pin 17 upwards rotates and withstands the restoring board bore edges restoring board is moved upward, other reset hole edge on the plate promptly acts on the code pins tapered slope that is in the position, back, it is pushed away forward reset.
