Description

Jack type cipher lock and private key

Technical field

The utility model belongs to a kind of lockset, the particularly a kind of jack type cipher lock and private key of unblanking with master key of preventing.

Background technology

Lock core of the prior art has many kinds, and the lock core of single-row billiard is arranged, and the lock core of many row's pellets shot from a slingshot is also arranged, but no matter is the lock core of single-row billiard or the lock core of many row's pellets shot from a slingshot, can open it with master key for the people with the skill of necessarily unblanking.This provides opportunity for some lawless persons, and the offender who has pretends to be the household technician that please unblank to open door lock and steal, and what also have acquires some skill of unblanking, and steals then.Thereby existing lockset can not play antitheft effect fully, gives a kind of sense of insecurity of people.

Coded lock also is a kind of lockset, and it mainly is made of the turning cylinder that has dial, pipe spreader, active rotating disk, driven rotating disk, handle, inserted link etc.Wherein, pipe spreader is sleeved on the turning cylinder, initiatively all have gap on rotating disk and the driven rotating disk, initiatively rotating disk is installed in the rotation the tip of the axis, driven rotating disk is installed on the pipe spreader, on active rotating disk and driven rotating disk boss or straight pin is arranged all, and facilitating the use initiatively, rotating disk drives driven dial rotation, a plate is arranged on the described inserted link, and hinged by a disk and handle.Gap on active rotating disk and driven rotating disk overlaps, and is positioned at plate when below, and handle can rotate, and inserted link could withdraw from from jack, and Men Caike opens.This coded lock is because relatively simple for structure, and theftproof performance is not good, and when the offender often can rely on rotation scale, sound and sense of touch that active rotating disk and driven rotating disk contact with plate opened it, and anti-theft effect is difficult to satisfactory.

Summary of the invention

The technical problems to be solved in the utility model is, overcomes the problem that is opened easily that existing password is latched in, and provides a kind of theftproof performance good and prevent jack type cipher lock and the private key opened with master key.

The utility model jack type cipher lock has a shell that has dial, lock shaft is housed in the enclosure, its special character is, rotation lock collar, combination disk and end face combination disk are housed on lock shaft, the key hole that mutual correspondence is arranged on rotation lock collar, combination disk and end face combination disk, the shelves stake of mutual promotion also is housed on rotation lock collar, combination disk and end face combination disk, has in the enclosure and the corresponding pellet shot from a slingshot of key hole hole, spring and pellet shot from a slingshot are housed in the pellet shot from a slingshot hole.

In order to open above-mentioned jack type cipher lock, the utility model also has a private key that matches and use with it, it has a columnar key body, in key body, be equipped with and the corresponding inserted link of key hole that rotates on lock collar, combination disk and the end face combination disk, utilize inserted link to stir rotation lock collar, combination disk and end face combination disk and rotate, make its key hole corresponding mutually, and promotion pellet shot from a slingshot, make it be in the enable possition, rotate private key and drive the lock shaft rotation, lock can be opened.

Advantage of the present utility model is:

1, in lock core, is provided with rotation lock collar, combination disk and the end face combination disk of jack, constitute the first line of defence of unblanking, if no unlocking cipher, then can't be with the jack on rotation lock collar, combination disk and the end face combination disk to last, each combination disk all constitutes barrier one, and any key or rod-like articles all can not be inserted in the lock core, prevent that him from unblanking by the human master key, and decoding the time does not have any especial sound and sense of touch, thereby password is not easy to be cracked, and is difficult to improper means unlatching.

2, in lock core, be provided with some groups with private key on the pellet shot from a slingshot that matches of inserted link, constitute the defence line, second road of unblanking, if there is not private key, pellet shot from a slingshot just can not be in the position of unlatching, lock shaft just can't rotate, lock core also can't be opened.

3, coded lock and cylinder lock are combined, constitute twice and unblank have private key not have password not drive lock in the defence line, had password not have private key also not drive lock, theftproof performance is splendid, and is solid and reliable, practical, is a kind of relieved lockset that makes us.

4, be convenient to install, of many uses, both can be used for also can be used on various vehicles and the motorcycle on various security doors, the safety cabinet, and manufacture craft is simple, low production cost.
