Abstract
The utility model relates to a lock-manufacturing field, and the utility model is particularly relates to a mechanical puzzle lock which is used for matching products of safes, security doors, etc. in use. The utility model is composed of a digital wheel, a positioning disk and a pin rod lock slice, wherein, a plurality of groups of mark scales are arranged on the positioning disk of the puzzle lock, and the mark scales form corresponding relationship with the scales on the digital wheel. A positioning mark on the positioning disk is composed of a plurality of different color marks or marked by digital numbers, and the marks can be identified by a service life. The safe coefficient of the puzzle lock can be remarkably improved by the implementation of the utility model.
Description
The utility model relates to the lockmaking field, refers more particularly to a kind of matching used mechanical code lock on the products such as strongbox, safety door that is used for.
Mechanical code lock is to be widely used in one of ancillary facility on strongbox, the safety door.Common this mechanical code lock has comprised following several parts: digital wheel, positioning disk, pin rod locking plate etc., the pin rod locking plate is generally three, leaving certain gaps uncovered by the economic plan on it, control its activity by the data code wheel, dial in password by the left-right rotation digital wheel, make three breach alignment on the pin rod locking plate, allow the pin rod on the door insert, realize unblanking.Common combination padlock only is provided with one group of number, utilizes the ad-hoc location on the positioning disk to carry out password confirming, realizes the locking plate location.This password that is made of three groups of numbers more easily is decrypted, and increase the password number and then will increase locking plate quantity, thereby bring the volume of lock to increase.
The purpose of this utility model is to provide a kind of can overcome above-mentioned defective, not changing lock construction and increasing on the basis of cost, increases the secret coefficient of lock.
The utility model is realized by following manner:
The utility model is realized by following manner; Constitute the main body of mechanical code lock by digital wheel, positioning disk, pin rod locking plate, digital wheel is umbrella, have a major axis, the positioning disk center is a circular hole, the major axis of digital wheel is interspersed in the positioning disk center, the pin rod locking plate is installed on the major axis, it is characterized in that: be provided with the witness marker group on positioning disk, form corresponding relation with scale on the digital wheel.Witness marker component on the positioning disk becomes several groups, and the sign in each group perhaps carries out label with number with different color identifications, to help the identification to sign.
The beneficial effect that has following two aspects by enforcement of the present utility model, the secret effect of the first significantly improves: common mechanical code lock has only one group of password, is decrypted easily, after increasing witness marker, formed the combination of multiple cipher, secret coefficient can improve hundreds of times.Even the password of strongbox was revealed, the witness marker that can not find on the positioning disk can not be opened coded lock.It two is that technology is simple: the utility model is that existing machinery formula coded lock is simply transformed, thus all can supporting use to original production technology, very help technological updating of enterprises and user's change voluntarily.
Below with reference to accompanying drawing the utility model is made further detailed description:
As scheming: Fig. 1 is a surface texture schematic diagram of the present utility model, and Fig. 2 is a vertical structure schematic diagram of the present utility model.Among the figure: 1, positioning disk; 2, digital wheel; 3, witness marker group; 4, pin rod locking plate.
Embodiment one:
Constitute the main body of mechanical code lock by digital wheel 2, positioning disk 1, pin rod locking plate 4, digital wheel 2 is umbrella, have a major axis, pin rod locking plate 4 is installed on the major axis of digital wheel, positioning disk 1 center is a circular hole, the major axis of digital wheel 2 is interspersed in positioning disk 1 center, is provided with witness marker 3 on positioning disk 1, forms corresponding relation with scale on the digital wheel 2.Witness marker 3 on the positioning disk 1 is divided into four groups, and each group is made of six different color signs again, to help the identification to sign.Embodiment two:
Constitute the main body of mechanical code lock by digital wheel 2, positioning disk 1, pin rod locking plate 4, digital wheel 2 is umbrella, have a major axis, pin rod locking plate 4 is installed on the major axis of digital wheel, positioning disk 1 center is a circular hole, the major axis of digital wheel 2 is interspersed in positioning disk 1 center, is provided with witness marker 3 on positioning disk 1, forms corresponding relation with scale on the digital wheel 2.Witness marker 3 usefulness numbers on the positioning disk 1 carry out label, to help the identification to sign.
