Description

Rotary lock core of lock body and private key

Technical field

The invention belongs to a kind of lockset, rotary lock core of particularly a kind of lock body and private key.

Background technology

Lock is all indispensable apparatus of huge numbers of families and all trades and professions, and it plays the important function of protection family or national wealth safety.The core component of lock is a lock core, and the theftproof performance of lock core is the key index of lock.Existing lock core mainly is made up of lock body, lock core, the plate of unblanking, spring and pellet shot from a slingshot; The plate of unblanking is fixed on the front end of lock core; Lock core is installed in the lock body, and can rotate therein, and keyhole is arranged in lock core; The cross section of keyhole is in-line or cross, and spring and pellet shot from a slingshot are installed in the pellet shot from a slingshot hole of lock body and lock core.The topmost problem that this lock core exists is exactly that theftproof performance is poor, and it is unreliable to use, and the master-hand that unblanks just can open with the slightest effort, and the principal element of opening easily still is the structure problem of lock core.Because pellet shot from a slingshot is the arrangement of axially embarking on journey, therefore, no matter pellet shot from a slingshot is single or double, and the position of pellet shot from a slingshot is all confirmed, grasps the special-shaped unlocking tool of human of certain skill and invades the pellet shot from a slingshot compression that lock core will be embarked on journey, and just can lock be opened.And in-line or criss-cross keyhole are because aretation also helps the use of instrument, and the somebody just can make the lock core rotation with master key even with an iron wire, and lock is opened.Therefore, the theftproof performance difference of lock core is puzzlement people's a big problem always.

Summary of the invention

The technical problem that the present invention will solve is, overcomes existing poor, the unserviceable problem of lock core theftproof performance, and rotary lock core of good, the safe and reliable lock body of a kind of theftproof performance and private key are provided.

The rotary lock core of lock body of the present invention comprises shell, lock core, the plate of unblanking, spring and pellet shot from a slingshot, and its special character is that the keyhole on the lock core is a circular hole; Lock core and shell are fixed together; Reticulate pattern sheath and rotation lock body are installed between shell and lock core, and the plate of unblanking is connected with the rotation lock body through the lock body butt plate, and the through hole that rotates the reticulate pattern sheath is arranged on the circumference of shell; Described spring and pellet shot from a slingshot are installed in the pellet shot from a slingshot hole of rotation lock body and lock core; Spring and pellet shot from a slingshot for radially becoming the row setting, stagger between every row pellet shot from a slingshot, with the pick-proof ability of raising lock core in lock core and rotation lock body in the axial direction each other.

Also be provided with sliding tray and end cap is installed in the outer end of lock core, the slide block of shutoff keyhole is installed in sliding tray, spring is installed, guarantee that the slide block shutoff is on keyhole in the outboard end of slide block.

In the rotation lock body, positioner is installed also, positioner is made up of spring and positioning bead, and the pit that matches with positioning bead is arranged on lock core, makes the rotation lock body be parked in the position of unblanking and closing lock accurately.

Private key of the present invention comprises handle and key bar, and described key bar is cylindrical, and the pit that matches with pellet shot from a slingshot is arranged on key bar, and pit is provided with for radially becoming to be listed as, and staggers each other in the axial direction between every row pit.

The front end of described key bar is conical, so that back down slide block, enters in the keyhole on the lock core.

The invention has the advantages that:

1, pellet shot from a slingshot radially becomes the row setting in lock core and rotation lock body; And stagger each other in the axial direction between every row pellet shot from a slingshot, changed the traditional structure that pellet shot from a slingshot is axially embarked on journey and arranged in the lock core, the pellet shot from a slingshot arrangement of not embarking on journey in the axial direction; Thereby be not easy to take off sled; Just can't open without private key, improve the pick-proof ability of lock core greatly, improve the theftproof performance of lockset.

2, keyhole is a circular hole, and master key and special-shaped unlocking tool can't be played a role, and has further improved the pick-proof ability of lock core, and is safe and reliable.

3, the slide block of shutoff keyhole is set in the outer end of lock core, can prevents that foreign matter from inserting, and increase the difficulty of picking lock.

4, lock core and shell are fixed together, and when unblanking, key and lock core do not change, reticulate pattern sheath and rotation lock body rotation, structure is unique, the scope of application is wide, can be used on any lockset, also can with the use that matches of other lock cores.
