Abstract
The utility model relates to a self-locking anti-theft lock. An annular groove is machined in an outer surface of an inner core, corresponding to one of the ball holes, and an annular ring is installed in the annular groove. A ball with a V-shaped annular groove is installed on the annular ring of the inner core, a movable pin is installed on one side, perpendicular to the ball with the V-shaped annular groove in the inner core, and a spring bayonet lock is installed in a jacket. When the anti-theft lock is opened abnormally, a V-shaped protrusion at one end of the movable pin is difficult to place in the V-shaped annular groove of the ball with the V-shaped annular groove, when the inner core is turned, the one end of the movable pin is placed in a hole, corresponding to the movable pin, of the annular ring, and the annular ring is driven to rotate. Due to the rotation of the annular ring, the front end of the movable pin in the jacket penetrates through the through hole in the annular ring and goes deeper into a blind hole in the inner core, the inner core is enabled to be stuck, and the technical opening cannot be achieved.
Description
Technical field:
The utility model relates to a kind of lockset, and particularly a kind of self-locking antitheft lockset, belong to hardware machinery lockset manufacturing technology.
Background technology:
In order to improve theftproof performance, in self-locking antitheft lockset in the past, someone has designed a kind of lock with protective sheet and locking groove, and the patent No. is: although 200320113865.6 this lock cores increase on theftproof performance,, also exist deficiency, if adopt first push-tight with respect to the pellet on protective sheet, and then the method for loosening, lockset still can be unlocked, therefore, theftproof performance is poor.Also have the patent No. to be: 200420108679.8 self-locking anti-theft lock, this self-locking anti-theft lock design is loaded down with trivial details, and manufacturing cost is too high, so effect is not fine.Shenyang China first prison patent inventor Mr. Chen Bo has designed the very simple self-locking anti-theft lock of a kind of making on the thinking of self-locking anti-theft lock, its objective is in order to make lock core structure tighter, better improve theftproof performance, and, reduce cost of manufacture, make it become the good product that numerous clients more accept.
Summary of the invention:
The utility model purpose has been to provide a kind of self-locking antitheft lockset.In common spring hole in lock core, common spring is installed, the self-locking antitheft lockset is except the essential characteristic with lock core; Its technical scheme is: on the external surface of inner core, be processed with a cannelure on the position with respect to one of them marble hole, an annular ring is installed in cannelure.
A pellet with V-ring shape groove is installed in the locational marble hole of annular ring in the middle of inner core, and with the rear end mounting spring of the pellet of V-ring shape groove, shut with shutoff the rear end of spring; Be processed with a movable pin-and-hole perpendicular to the side with the pellet of V-ring shape groove in inner core, a removable pin is installed in movable pin-and-hole.
In overcoat, with respect to a spring detent is installed in the locational marble hole of annular ring in inner core.The external surface of described pellet with V-ring shape groove is processed with one with the groove of V-ring shape.One end forming V-shape convex of described removable pin, it is plane that the other end becomes, and, an end in the V-arrangement convex is processed with a circle projection, a spring is installed on removable pin, the round-meshed shutoff of Intermediate Gray is installed in the rear end of removable pin, and on removable pin, the plane end of one-tenth can be movable in the circular hole in the middle of shutoff.Respectively process a blind hole with respect to the both sides with the pellet of V-ring shape groove in described cannelure on the external surface of inner core.
Be processed with the through hole of same diameter on described annular ring with respect to the blind hole position on inner core, and, be processed with a hole on the position with respect to removable pin, when opening not, the end with the plane on removable pin can be movable in this hole.
Described spring detent only is arranged in the middle of overcoat, the rear end mounting spring of spring detent, and shut with shutoff the rear end of spring; When opening not, the lower end of spring detent withstands on annular ring.
The anti-theft device that is made of annular ring, the pellet with V-ring shape groove, removable pin, spring detent can be one, can be also a plurality of.
The characteristics that this self-locking antitheft lock core has are: except the essential characteristic with lock core, be provided with annular ring in lock core, also have spring detent with pellet and the removable pin of V-ring shape groove.When technical opening, common spring can technical opening, but whether the V-arrangement projection of removable pin one end is placed in fully with in the V-ring shape groove on the pellet of V-ring shape groove, and technical opening the people do not know yet, when rotating inner core, due to, the V-arrangement projection of removable pin one end is not placed in fully with in the V-ring shape groove on the pellet of V-ring shape groove, at this time, an end on removable pin can be placed on annular ring in hole on the other side, drives annular ring when inner core rotates and rotates together; And this moment is due to the rotation of annular ring, the pressure of the spring of the movable bayonet lock rear end in overcoat can make the front end of movable bayonet lock pass through hole on annular ring, and be deep in inner core with respect in the locational blind hole of through hole, inner core is stuck, can not be rotated further; Again 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; Pellet with V-ring shape groove extends best; Removable pin is placed in hole on annular ring because the strength of spring makes on removable pin an end with the plane; One end of spring detent withstands on annular ring.
When normal unlatching, key inserts in keyhole, and common spring projection bottom and tartar on the key match, and matches with the pellet projection bottom of V-ring shape groove and tartar on the key; This moment, the V-arrangement projection of removable pin one end was placed in fully with in the V-ring shape groove on the pellet of V-ring shape groove, and an end of removable pin separates in the hole from the annular ring fully, is placed in movable pin-and-hole.
Rotate inner core, because the front end of movable bayonet lock withstands on annular ring, can only make inner core oneself rotation, annular ring can not rotate, and lock core is normally opened.
, novel structure, reasonable ingenious, rational in infrastructure due to this lock core design have better theftproof performance.
