Abstract
The utility model relates to a self-locking type anti-theft lock cylinder. A ring-shaped projection billiard or a movable slice-type billiard is installed in the lock cylinder, one side perpendicular to the ring-shaped projection billiard or a movable slice-type billiard in the lock cylinder is provided with a movable pin, a movable bayonet lock is installed in the billiard hole which is arranged in the casing and positioned on the place corresponding to the ring-shaped projection billiard or a movable slice-type billiard in the lock cylinder, and a spring bayonet lock is installed in the lock cylinder on the side opposite to the movable lock cylinder. When startling a lock improperly, the projection on the ring-shaped projection billiard or a movable slice-type billiard is difficult to be jointed together with the projection of one end of the movable pin, when the lock cylinder is rotated, the lower end of the movable bayonet lock deeps into the hole of the movable pin inside the lock cylinder and locks the lock cylinder, moreover the spring bayonet lock can be locked in the annular neck on the movable bayonet lock and the lock cylinder can be locked deadly, so a lockset is hard to be opened by improper means.
Description
Technical field:
The utility model relates to a kind of lock core, and particularly a kind of self-locking antitheft lock core belongs to hardware machinery lockset manufacturing technology.
Background technology:
In order to improve theftproof performance, some inventors have invented multiple self-locking antitheft lock core, although these lock cores increase at theftproof performance,, also exist deficiency, the one, theftproof performance is poor.The 2nd, the lock design is complicated, and manufacturing cost is high, so effect is not fine.
Summary of the invention:
The utility model purpose has provided a kind of self-locking antitheft lock core.In the common spring hole in lock core common spring is installed, the self-locking antitheft lock core is except the essential characteristic with lock core; Its technical scheme is: an annular protrusion pellet is installed in one of them marble hole in the middle of inner core.Perhaps in inner core, dig the marble hole of a movable chip pellet, a movable chip pellet is installed in the marble hole of movable chip pellet.Side perpendicular to annular protrusion pellet or movable chip pellet in inner core is processed with a movable pin-and-hole, and a removable pin is installed in the movable pin-and-hole.
In overcoat, a movable bayonet lock is installed in the marble hole on the seat relative with this annular protrusion pellet in the inner core or movable chip pellet; Side with respect to this movable bayonet lock in overcoat is installed a spring detent.
Described annular protrusion pellet only is installed in the middle of the inner core, and the external surface of annular protrusion pellet has two annular grooves, and the centre of two annular grooves folds the shape that circularizes projection.Described movable chip pellet only is installed in the middle of the inner core, and a side of movable chip pellet is processed with a groove, and the shape of projection is processed in the centre of groove, and the opposite side of movable chip pellet is processed with a projection that is used for bearing spring.
One end of described removable pin becomes convex, and it is plane that the other end becomes, and an end of removable pin projection is toward annular protrusion pellet or the direction of movable chip pellet; Removable pin can be one or two.
Described movable bayonet lock only is installed in the middle of the overcoat, the rear end mounting spring of movable bayonet lock, and shut with shutoff the rear end of spring, is processed with annular slot on the movable bayonet lock.
Described spring detent only is installed in the middle of the overcoat, the rear end mounting spring of spring detent, and shut with shutoff the rear end of spring.
The characteristics that this self-locking antitheft lock core has are: except the essential characteristic with lock core, be provided with annular protrusion pellet or movable chip pellet and removable pin and also have movable bayonet lock and spring detent in lock core.When technical opening, common spring can technical opening, but, projection in the middle of annular protrusion pellet or the movable chip pellet whether with the high spot of removable pin one end at same relative position, technical opening the people do not know yet, when being rotated further inner core, turn to the other end of removable pin relative with movable bayonet lock the time, because, the projection in the middle of annular protrusion pellet or the movable chip pellet and the projection of removable pin one end do not have relative together, two raised points are misplaced, at this time, the spring of the movable bayonet lock rear end in the overcoat can make the front end of movable bayonet lock be deep in the movable pin-and-hole in the inner core, and inner core is stuck, and can not be rotated further; And after the movable bayonet lock activity of this moment, spring detent is because the effect of spring, the front end of spring detent is deep in the annular slot on the movable bayonet lock, because the effect of spring detent makes the movable bayonet lock can not return, removable pin also can't return, the lock core of this moment can't be realized technical opening by locked.
Operating principle of the present utility model:
When non-opening, common spring reaches ultimate attainment; Annular protrusion pellet or movable chip pellet extends best; One end of movable bayonet lock withstands in the shutoff of annular protrusion pellet rear end, an end of spring detent withstand on movable bayonet lock outer wall on.
When normal unlatching, key inserts in the keyhole, and common spring projection bottom and tartar on the key match, and annular protrusion pellet or movable chip pellet projection bottom and tartar on the key match; The high spot of the projection in the middle of annular protrusion pellet or the movable chip pellet and removable pin one end is at same relative position at this moment, rotate inner core, when the plane of the other end that turns to removable pin and movable bayonet lock cross, because the projection of removable pin one end is in same relative position with the annular protrusion of annular protrusion pellet centre, make the plane of the other end of removable pin concordant with the inner rotary face of inner core; At this moment the front end of movable bayonet lock can slip on the inner rotary face of inner core; Lock core is normally opened.
Or rotation inner core, when the plane of the other end that turns to removable pin and movable bayonet lock cross, because the high spot of the projection of removable pin one end and movable chip pellet centre at same relative position, makes the plane of the other end of removable pin concordant with the inner rotary face of inner core; At this moment the front end of movable bayonet lock can slip on the inner rotary face of inner core; Lock core is normally opened.
Because ingenious, rational in infrastructure, the novel structure, reasonable of this lock core design has better theftproof performance.
