Description

Lock body rotating lock cylinder and private key

Technical field

The invention belongs to a kind of lockset, particularly a kind of lock body rotating lock cylinder 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 lock core, and the theftproof performance of lock core is the key index of lock.Existing lock core mainly consists of lock body, lock core, the plate of unblanking, spring and pellet, the plate of unblanking is fixed on the front end of lock core, lock core is arranged in lock body, and can rotate therein, keyhole is arranged in lock core, the cross section of keyhole is in-line or cross, and spring and pellet are arranged in the marble 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, the principal element of easily opening or the structure problem of lock core.Because pellet is axial arrangement in a row, therefore, no matter pellet is single or double, and the position of pellet all determines, the people who grasps certain skill invades with special-shaped unlocking tool the pellet that lock core will embark on journey and compresses, and just lock can be opened.And in-line or criss-cross keyhole, due to aretation, also are conducive to the use of instrument, and the somebody even just can make the lock core rotation with an iron wire with master key, and lock is opened.Therefore, the theftproof performance of lock core is poor is puzzlement people's a large problem always.

Summary of the invention

The technical problem to be solved in the present invention is, overcomes existing poor, the unserviceable problem of lock core theftproof performance, and good, the safe and reliable lock body rotating lock cylinder of a kind of theftproof performance and private key are provided.

lock body rotating lock cylinder of the present invention comprises shell, lock core, the plate of unblanking, spring and pellet, its special character is, keyhole on lock core is circular hole, lock core and shell are fixed together, reticulate pattern sheath and rotation lock body are installed between shell and lock core, unblank plate by the lock body butt plate with the rotation lock body be connected, the through hole that rotates the reticulate pattern sheath is arranged on the circumference of shell, described spring and pellet are arranged in the marble hole of rotation lock body and lock core, spring and pellet are setting radially in column in lock core and rotation lock body, mutually stagger in the axial direction between every row pellet, to improve the pick-proof ability of lock core.

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, in the outboard end of slide block, spring being installed, guaranteeing that the slide block shutoff is on keyhole.

In the rotation lock body, positioner also is installed, positioner consists 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 accurately the position of unblanking and shutting.

Private key of the present invention comprises handle and key bar, and described key bar is cylindrical, and the pit that matches with pellet is arranged on key bar, and pit is setting radially in column, and mutually staggers 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 lock core.

The invention has the advantages that:

1, pellet in lock core and rotation lock body central diameter to setting in column, and mutually stagger in the axial direction between every row pellet, changed the traditional structure of the axial arrangement in a row of pellet in the lock core, pellet is arrangement in a row not in the axial direction, thereby be not easy to take off sled, just can't open without private key, greatly improve the pick-proof ability of lock core, improve the theftproof performance of lockset.

2, keyhole is 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 while unblanking, key and lock core do not turn, 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.
