Abstract

The utility model relates to a cylinder lock, which comprises a lock body, a lock tongue, and a lock head, wherein, the lock head is composed of a fixing lock head body and a rotatable lock core; a tooth slot and a cylinder are arranged in the loc head; the different point is that the lock core is divided into two sections or three sections. Each section of the lock core of the utility model can independently and freely rotate, and hence, the lock can not be unlocked by using thin and hard objects with the methods of pulling out and hooking the tooth slot, the normal unlocking method and the various application of the lock are not influenced, and simultaneously, the utility model can prevent being unlocked by a master key made of steel pieces, etc.

Description

A kind of cylinder lock

The utility model relates to a kind of improvement of cylinder lock.

Existing spring lock generally comprises the parts such as lock body, dead bolt, tapered end, tapered end comprises rotating lock core and fixing tapered end, in be provided with row's pellet, only lock core could rotate when all pellets are in ad-hoc location simultaneously, thereby drive the dead bolt motion, will lock unlatching.For this lock, the burglar can use that small objects is drawn, the briar tooth groove, or additional simultaneously twisting resistance, makes pellet shot from a slingshot be in the enable possition and lock is opened.

The purpose of this utility model provides a kind of spring lock, except having traditional spring lock function, can also prevent that the burglar from using thin hard object to draw out this lock.

Scheme of the present utility model is: comprise lock body, dead bolt and tapered end, tapered end is made of fixing tapered end and rotating lock core, in establish teeth groove and pellet, difference is that lock core is two sections or three sections that separate.

In the such scheme, having a pair of in the set pellet in tapered end is the insurance pellet that often is in opening.

Lock core of the present utility model is divided into two sections or three sections, but because every section equal independence and freedom rotation, so the thin hard object employing of use is drawn, the method for briar tooth groove can not be opened, and the various application of its normal open method and lockset are all unaffected.Establish the insurance pellet of a pair of opening in the pellet that arranges, can prevent the unlatching of the skeleton key made with things such as steel discs, face is not affected by it through the key of rationally design, can normally open.

Accompanying drawing is the utility model lock core structure figure.

Lock core 2 among the figure is divided into independently two sections, and every section is all free to rotate, in establish one row pellet 3.Insurance pellet shot from a slingshot 4 is positioned at inner end, and often is in the enable possition.The key that matches therewith can only withstand the pellet shot from a slingshot of front, and is inoperative in the face of insuring pellet shot from a slingshot.As when using the instrument such as skeleton key, can stir the insurance pellet and lock core can not be rotated.1 is tapered end among the figure.

Claims

1, a kind of spring lock comprises lock body, dead bolt and tapered end, and tapered end is made of fixing tapered end and rotating lock core, in establish teeth groove and pellet, it is characterized in that lock core is two sections or three sections that separate.

2, by the described cylinder lock of claim 1, it is characterized in that having in the pellet shot from a slingshot set in tapered end a pair of is the insurance pellet shot from a slingshot that often is in opening.
