Description
The utility model relates to a kind of easy Coded bullet lock, is made up of common spring lock, Cipher mechanism and alarm mechanism, can be widely used in various doors, cabinet, drawer and vehicle.
Existing Coded bullet lock, of a great variety, purposes is different.As No. 90222188.4 disclosed Coded bullet locks of Chinese patent, comprise billiard mechanism, Cipher mechanism, hoisting mechanism and automatic mess code mechanism, pellet shot from a slingshot is common and special-shaped two groups, the hoisting mechanism of band plectrum and one way valve interrelates billiard mechanism and Cipher mechanism.Its complex structure is difficult to popularization and application.
The purpose of this utility model provides a kind of simple in structure, Coded bullet lock that security performance is good.
A kind of easy Coded bullet lock, itself and corresponding outer lock core pellet shot from a slingshot hole, internal cylinder pellet shot from a slingshot hole are through hole, and the boss shape pellet shot from a slingshot is set in the hole, and the outer lock core outside is with the sleeve of rotatable displacement, and drum surface is provided with and the corresponding open keyhole of boss shape pellet shot from a slingshot.Have only when several boss shape pellets shot from a slingshot and aim at, insert key and can open lockset with open keyhole.The internal and external threads that matches is set respectively on sleeve and the outer lock core.The sleeve outer face is provided with scale, so that aim at password.
This Coded bullet lock has simple in structure, and is of many uses, and the characteristics that security performance is strong only increase major part of sleeve than existing cylinder lock, and cost is low, easily popularizes and carries out.
Accompanying drawing is an example structure schematic diagram of the present utility model.
Referring to accompanying drawing, lock core marble hole is respectively established three row up and down, and the plain cylindrical form pellet shot from a slingshot is set in the internal cylinder 1, and outer lock core 2 is upper and lower to be provided with two and a boss shape pellet shot from a slingshot 4 respectively, is provided with three open keyholes 5 with three corresponding places of boss shape pellet shot from a slingshot on the sleeve 3.But first boss shape pellet shot from a slingshot A double as alarm switch of key insertion end: when being provided with alarm mechanism, if at first sleeve is not rotated in place by password and just inserts key, can make boss shape pellet shot from a slingshot A upwards run into sleeve atresia place, promptly connect the power switch that is provided with alarm.Also can not establish alarm mechanism.The quantity of boss shape pellet shot from a slingshot is generally 1-9 only, the place of need to be keep secret, and the boss shape pellet shot from a slingshot is many more, also pellet shot from a slingshot can be set along the circumferential direction.Sleeve also can be designed to plug-type, have only when sleeve axially and the end face scale on time, can unblank.
The utility model can also also be established a sleeve between inside and outside lock core, or inside and outside lock core all is designed to make it mess code turnably, increases confidentiality.
