Abstract
The utility model discloses a cipher lock with a steel ball sealed hole, which uses the technical proposal that a steel ball is used for sealing a keyhole, a cipher is additionally arranged at the front end of lock head, and a magnetic column pin is arranged on a lock shell; different cipher symbols are provided with the replacement of N and S poles, and thus, the cipher repetition rate of each lock is very low. In addition, a cipher ring is arranged at the front end of a lock body so as to control the steel ball to seal the keyhole mechanism. The utility model solves the problem of the occurrence of the phenomenon of unlocking through blocking the keyhole with foreign matters and by master keys, and thus, enhances the self safety performance of the lock.
Description
The utility model belongs to lock technology field, is specifically related to a kind of technological improvement to existing password lock opening structure.
The insurance function majority of existing machinery formula coded lock is by a cover digital check mark dish and the outside plug type key to be controlled, and the safety lock of this mechanism exposes because of lockhole, is very easy to stop up foreign matter, makes key to insert, and causes a whole set of lockset to be scrapped.
The purpose of this utility model is to provide a kind of steel ball sealing of hole coded lock, is intended to stop to stop up in the not anti-drilling and past lockhole of lockhole the phenomenon generation of foreign matter.
For achieving the above object, the technical solution adopted in the utility model: set up a steel ball sealed key hole at the tapered end front end, the front end face cover interlayer of lock core and lock housing, set up the mechanism arrangement of cipher ring control steel ball, some magnetic pins are set on the lock housing, a thrust spring is all settled in each magnetic pin bottom, each magnetic pin can be along N, S utmost point linear slide, by magnetic pin N, S utmost point permutations, can be combined into the identical or different cipher symbol of magnetic pin end face polarity, be equipped with the magnetic key identical again with quantity on the tapered end, magnetic pin N on the key, the S utmost point settles the polarity cipher symbol that forms corresponding with cipher symbol in the tapered end, and polarity is opposite.
Below in conjunction with accompanying drawing the technical solution of the utility model is further described:
Fig. 1---tapered end phantom
Fig. 2---Key structure schematic diagram
The utility model structure comprises tapered end, key two parts: Fig. 1 illustrates tapered end part sectional structure, lock housing (1) is hollow step cylinder, have some blind holes on the wall circle within it, settle a thrust spring (2) and magnetic pin (3) in each blind hole, lock core (4) is sleeved in the lock housing (1), on lock core (4) cylindrical end face, be processed with some holes nest with corresponding place, lock housing (1) blind hole position, be provided with cipher ring (5) and cipher ring (6) transmission mechanism at the tapered end front end, on the cipher ring inwall, respectively open a breach (7), cipher ring (5) front end is provided with digital calibration and shows, lock core (4) is gone up in the elongated slot through hole clamp (8), steel ball (9) is placed in the keyhole (10), steel ball (9) back pocketed springs (11) and driving lever (12), the hole of lock core tail end is provided with latch in (13), and lock housing and lock core tail end are provided with jump ring (14); Fig. 2 illustrates Key structure: key (15) main body is cylinder, and magnetic pin (16) is settled in perforate on the face of cylinder in the hole, and magnetic pin (16) is identical with magnetic pin quantity in the lock housing (1), and its position is correspondence one by one, and polarity is opposite.When unblanking, split password insert key head on steel ball (9) spring (11) in keyhole, retreat put in place after, corresponding magnetic pin (3) retraction on the lock core firmly one is twisted, lock core rotates, this is an opening.Extract key when locking, the magnetic pin (3) on the lock housing is pushed in lock core (4) the surface holes nest under the effect of spring force, and the control lock core rotates, upset password after, cipher ring blocks steel ball, steel ball is sealing keyhole, this is a closed condition.
The utility model advantage: adopt steel ball sealing its keyhole, be provided with two covers on lock housing and the cipher ring Password, especially the magnetic pin can be combined into very many passwords by permutations in the tapered end Symbol, thereby the password repetitive rate of every lock is extremely low, has set up steel ball sealing key in the lockhole The hole has thoroughly stopped to stop up foreign matter in the past lockhole and electric drill destroys.
Claims (1)
