Description

Lock is opened in dislocation

Technical field

The invention belongs to a kind of mechanical lock, relate in particular to a kind of tapered end of cylinder lock.

Background technology

Cylinder lock invention has had more than 160 year so far, based on it basic structure and the various locksets that design still are widely used in life now.Comprise rotary lock core in the lock body of cylinder lock, two pellets shot from a slingshot are arranged in the pellet shot from a slingshot hole of lock body and lock core, during locking, the contact surface of two pellets shot from a slingshot does not overlap with the contact surface of lock core and lock body, and pellet shot from a slingshot stops lock core to rotate; When lock left, the contact surface of two pellets shot from a slingshot overlapped with the contact surface of lock core and lock body, and lock core can rotate in lock body.The shortcoming of this lock construction is and can applies a revolving force to lock core, stirs pellet shot from a slingshot then and technical opening.Based on it basic structure and the various locksets that design as Chinese patent ZL 99115581.5 disclosed cylinder locks, are controlled lock core by the combining structure of pellet shot from a slingshot and locking side column; Chinese patent ZL 01266248.8 disclosed cylinder lock is controlled lock core by the pellet shot from a slingshot and the combining structure of card key.The improvement structure of these cylinder locks, though increased the technical opening difficulty, when being in the open and close state because of lock core, since the effect of side spring force, the stressing conditions difference of pellet shot from a slingshot, thus still can stir pellet shot from a slingshot and technical opening.Comprehensively as mentioned above, the difference of cylinder lock pellet shot from a slingshot stressing conditions when opening or locking states, and this moment, pellet shot from a slingshot can be stirred in the pellet shot from a slingshot hole, was that existing cylinder lock can be by the main cause of technical opening.

Summary of the invention

The purpose of this invention is to provide a kind of: when pellet shot from a slingshot can be stirred in the pellet shot from a slingshot hole, the stressing conditions that is locked in opening or locking states pellet shot from a slingshot was identical; When opening lock, pellet shot from a slingshot can not be stirred, thereby prevents the cylinder lock head of technical opening.

For achieving the above object, technical scheme of the present invention is: lock is opened in a kind of dislocation, comprise lock body and the lock core that can in lock body, rotate, outside, the middle ware of lock core have locking ring across lock body, a plurality of pellets shot from a slingshot hole is arranged on lock core, lock body, the locking ring, from marble spring, last pellet shot from a slingshot, following pellet shot from a slingshot, differential pellet shot from a slingshot, lock core marble are outside to inside arranged, rotatable lamella is arranged on the lock core in the pellet shot from a slingshot hole, with the rotatable lamella opposite position rotation slot is arranged on the locking ring, have error angle between rotation slot and the rotatable lamella.The length of differential pellet shot from a slingshot equates that with the differential of key tooth flower the quantity of the differential pellet shot from a slingshot in each pellet shot from a slingshot hole is corresponding with key tooth flower degree of depth grade, and the length of all lock core marbles is identical.In the return slotted eye of lock body and locking ring, return pin and return spring are arranged.

When above-mentioned cylinder lock head was in locking states, locking ring was by last pellet shot from a slingshot prevention activity.After lock core was inserting any key that with original key the identical keys base is arranged but be not complementary with lock core, locking ring was by last pellet shot from a slingshot or pellet shot from a slingshot prevention activity down; And the contact surface of lock core and lock body overlaps with the contact surface of certain differential pellet shot from a slingshot, though lock core can rotate, but because the rotation of rotatable lamella is subjected to the restriction of rotation slot, so rotate in the error angle that can only between rotation slot and rotatable lamella, exist, thereby can't rotate the opening mechanism that drives lockset in a wider context.After inserting original key, the contact surface of all going up pellet shot from a slingshot, following pellet shot from a slingshot overlaps with the contact surface of locking ring and lock body, no longer stops the activity of locking ring, and lock core is after rotating error angle, drive locking ring by rotatable lamella and rotate, then drive the opening mechanism of lockset then by locking ring.When lock core drives the locking ring rotation, owing to have error angle between rotatable lamella and the rotation slot, so lock core is different with the rotational angle of locking ring, when the home position is got back in the lock core rotation, return pin promotes locking ring and gets back to the home position under the effect of return spring.

Adopt said structure, when not rotation of lock core, lock core marble hole and lock marble hole are on the same axis, though it is movable in the pellet shot from a slingshot hole to stir pellet shot from a slingshot, but because the pellet shot from a slingshot in each lock core marble hole is identical, and locking ring does not have, can't be in stress yet, so can't determine to go up the residing position of pellet shot from a slingshot, also just can't be by technical opening.When lock core is rotated an error angle, thereby the rotation strip of lock core begins the time spent of doing of power that locking ring is applied, at this moment since lock core marble hole and lock marble hole not on same axis, thereby can't stir pellet shot from a slingshot activity in lock marble hole, so can technical opening yet.

Adopt said structure, as another kind of improvement the of the present invention, can design the mechanical strength of the mechanical strength of rotation strip less than the pellet shot from a slingshot that stops the locking ring activity, then lock core is being carried out brute force when rotarily opening, rotation strip is damaged prior to the locking pellet shot from a slingshot, and lock core can dally, but locking ring still can not rotate, also just can not drive the opening mechanism of lock, prevent that so effectively brute force from rotarily opening.
