Described keyhole is following profound month shape through hole, and its hole wall comprises segmental arc hole wall and the flat segments hole wall that cooperates with the curved surface tartar.
Described lock gall is provided with horizontal cut, be equipped with in the described horizontal cut when being stirred by the cylinder key drive that lock gall rotates on the shifting block of profound month shape, described lock gall shell is provided with the translot corresponding with described horizontal cut, in the described translot elastic collar is housed, the head of described cylinder key bar is provided with the plane of stirring that links to each other with described curved surface tartar.
In the front end of described lock gall chamber the fore-set of unblanking is housed.
Described retaining door is made by carbide alloy.
Described curved surface tartar is a spiral camber.
The cross sectional area at the curved surface tartar section place of described cylinder key bar equates.
Compared with prior art, the present invention has following advantage:
1, the present invention is simple in structure, does not need between the cipher chips at interval, and the lock core cipher sheet quantity of equal length is many, has reduced repetitive rate, and is safe and reliable.
2, lock core key of the present invention is the curved surface tartar to be set on cylindrical, and the section area of key key bar is identical, solid, firm and durable.
3, the present invention adopts shifting block and elastic collar to drive lock gall to rotate, and when non-cooperation key or other instruments entered hard sled, spring collar opened, skid between non-cooperation key or other instruments and the shifting block, and lock gall can not rotate, and effectively prevents illegal unlatching.
