Description

Special mechanical formula coded lock

The utility model relates to a kind of coded lock, accommodates in safety cabinet, strongbox, door, drawer etc.

The kind of Current Password lock is a lot, and wherein mechanical code lock mostly has the locking poor reliability, is difficult for shortcomings such as escape, preventing decryption difference, and some adopts dial-type password, inconvenient operation; The electronic type coded lock needs power supply and cost too high.

The purpose of this utility model is to provide a kind of reliability height, strong security, simple to operate, escape mechanical code lock easily.

The technical solution of the utility model is as follows: it is made up of button, dislocation cross lock core, jam plate, jump ring sheet, framework, compression spring, the push rod that resets, the push pedal that resets, fan-shaped spacer, wherein button comprises numerical key and reset key, the structure of each numerical key is identical, and each button all has corresponding supporting lock core, jump ring sheet, compression spring and fan-shaped spacer; Lock core and jam plate are formed locking mechanism, have circular hole corresponding and straight line chute on the jam plate with lock core, the dislocation cross lock core is contained on the lock shaft by two in-line locking plate vertical interlaced stack rivetings and constitutes, two end bearings are slidingly matched with panel, the backboard of framework respectively before and after the lock shaft of lock core, and this lock shaft front end is unsteady with button and cooperates; The jump ring sheet riveting of band hook is contained on the framework, and front and back two ends of the lock shaft of lock core all are set with the compression spring; The axle that links to each other with reset key in the button is the push rod that resets, its middle part is a cone, its assembly relation is identical with the lock shaft of lock core, the push pedal that resets is contained between the lock shaft and jump ring sheet of lock core, and it is perpendicular with the push rod that resets, resetting has some apertures in the push pedal, and the lock shaft of each lock core passes the aperture in the push pedal that resets; Fan-shaped spacer is installed on the backboard of framework.The lock shaft end of lock core is square, fan-shaped spacer has square opening and terminal for being slidingly matched with lock shaft in fan heart position, on the fan-shaped spacer be that the center has deep-slotted chip breaker along the fan limit, adopt screw to be connected and fixed by the deep-slotted chip breaker and the framework backboard of fan-shaped spacer with the square opening.

The utility model cooperates and to install mechanical lock additional and carry out safety locking, can realize functions such as antitheft, pick-proof effectively.

Below in conjunction with accompanying drawing in detail the utility model is described in detail

Fig. 1 is a front view of the present utility model;

Fig. 2 is the partial schematic diagram of internal construction of the present utility model;

Fig. 3 is the cross section view of dislocation cross lock core 2 and jam plate 3 connecting portions;

Fig. 4 is a back of the present utility model front view.

Fig. 1 to Fig. 4 has reflected structure of the present utility model, adopt 9 buttons, button 1 wherein shown in Figure 2 is a numerical key, totally 8, the button that links to each other with the push pedal 9 that resets with the push rod 8 that resets shown in the side is a reset key under button 1, and it can make other numerical keys restPose, and with password locking, numerical key is used to input password, therefrom can choose 2～7 any number of combinations code characters of number, and mechanism is realized password locking.Framework 5 is provided with guide rail, and jam plate 3 is tried hard to recommend down moving outside, can be along the guide rail move left and right on the framework 5.When in-line locking plate and the jam plate 3 of dislocation cross lock core 2 are in same plane, and during the dead in line of the straight line chute on in-line locking plate and the jam plate 3, just can make jam plate 3 move left and right, wooden utility model is in opening at this moment.When the axis of the chute circular hole on the jam plate 3 and in-line locking plate was vertical mutually, then jam plate 3 can not move, and promptly the utility model is in lock-out state.The lock shaft that promotes lock core 2 during button in axial direction moves, i.e. the plan-position of conversion in-line locking plate and jam plate 3 relation just can reach that to make initial conditions be to lock to change unlatching into, or to make initial conditions be the purpose that unlatching changes locking into.When pressing digital keys 1, the lock shaft that can promote lock core 2 moves inward, and jump ring sheet 4 will snap in the groove of lock shaft, and axle can not be return.Only press reset key, promote to reset push rod 8, drive the push pedal 9 that resets, the hook of jump ring sheet 4 is withdrawed from the groove of the lock shaft of lock core 2, lock shaft 2 just returns to initial position under the promotion of compression spring 6, promptly realizes resetting.Compression spring 7 cooperates the motion of button.

Fig. 4 is the schematic diagram of framework 5 backboards and fan-shaped spacer 10.Fan-shaped spacer 10 is used for the location and changes password.When changing password, press corresponding digital button, again the fan-shaped spacer 10 of correspondence is revolved and turn 90 degrees, rotate the lock shaft orientation of fan-shaped spacer 10 change lock cores 2, this lock shaft rotates and drives locking plate, the relative position of locking plate and jam plate 3 is changed, can realize the control function of this button like this jam plate 3.Among Fig. 4, corresponding reset key among the framework 5, all the other 8 the corresponding numerical keys of fan-shaped spacer.

The utility model is installed on the door such as case (cabinet).Cooperate control by the utility model with anti-drilling cylinder lock.Press the password that sets, jam plate is in active state, and key moves jam plate again, then opens.Institute is not fixed motionless to jam plate then by password, can't open.

In sum, the utility model is simple to operate, and locking is reliable, and escape is convenient, confidentiality, Preventing decryption is strong, is widely used in safety cabinet, safety box, door, drawer etc., and cooperation adds Installation tool door lock opposite house carries out safety locking, has the specific functions such as antitheft, pick-proof.
