Description
One. technical field:
The utility model relates to a kind of padlock, particularly relates to a kind of padlock that has composite lock core.
Two. background technology:
Lockset is the patron saint of people's property, if lockset goes wrong, people's property just can not be protected, but one of important means of robber's crime also is to start with from lockset, the one, realize unblanking by destroying, because this method needs bigger tool used in crime, its target is big, and sound of movement is big, so the offender does not generally use; The 2nd, unblank by the so-called master key of self so-called technology and autogamy, because this method is more hidden, be not easy to be found, so the offender often uses.Mostly be rotational structure greatly between lock core and the lock body at present, because the existence of machining error, it is poor to produce certain included angle when making two circles tangent, the existence of this angle difference, cause and to carry out changing joint to one by one pellet shot from a slingshot with foreign matter not as good as the tangent profound son of resistance, thereby on tangent round core face, form a profound sub line, make pellet shot from a slingshot out of control and unblank, the reason that Here it is no key or master key unblanked.
At these situations, people strengthen the intensity and the fastness of lockset on the one hand, improve the anti-pirate of the open performance of lock core on the other hand, as: people develop cross lock core, to strengthen the theftproof performance of lock.But, no matter be that I-shaped lock or the big multipotency of the cross lock craftsman that unblanked opens with technical approach, certainly, some thiefs also can be driven such lock, its reason also is that existing lock core generally all is to rotate to a direction, craftsman or the thief torsional forces when having key turns of unblanking is judged the position and the quantity of pellet shot from a slingshot, thereby opens lockset, makes lockset ineffective.
Three. the utility model content:
The purpose of this utility model: overcome the deficiencies in the prior art, provide a kind of modern design, simple in structure, security performance good, can adapt to the padlock that has composite lock core of large-scale production.
The technical solution of the utility model: a kind of padlock that has composite lock core, contain lock body, lock bridge, lock core and key, described lock core is made up of outer lock core and internal cylinder, wherein, outer lock core is a cylinder, internal cylinder is a semicylinder, internal cylinder is sleeved in the semicircle axially extending bore of outer lock core, the two can endwisely slip mutually, be respectively arranged with corresponding pellet shot from a slingshot hole on described outer lock core and the internal cylinder, described pellet shot from a slingshot is equipped with pellet shot from a slingshot and spring in the hole, offer keyhole on the described internal cylinder, and described internal cylinder one end is provided with plectrum, this plectrum is corresponding with the dead bolt shift fork in the lock body, described dead bolt shift fork is connected with dead bolt, and the circumferential surface of described outer lock core is provided with annular groove, and the external surface of described internal cylinder is provided with stopper slot, this stopper slot is corresponding with spacer pin or banking stop on the outer lock core, makes internal cylinder move axially a section with respect to outer lock core and moves; Described outer lock core is sleeved in the lock body, and described lock body is provided with alignment pin, and this alignment pin matches with annular groove on the described outer lock core, outer lock core can only be rotated and can not move axially.
Be provided with back-moving spring between described outer lock core and the internal cylinder, be provided with back-moving spring between described dead bolt shift fork or dead bolt and the lock body.
A kind of padlock that has composite lock core, contain lock body, lock bridge, lock core and key, described lock core is made up of outer lock core and internal cylinder, wherein, outer lock core is a cylinder, internal cylinder is a semicylinder, internal cylinder is sleeved in the semicircle axially extending bore of outer lock core, the two can endwisely slip mutually, be respectively arranged with corresponding pellet shot from a slingshot hole on described outer lock core and the internal cylinder, described pellet shot from a slingshot is equipped with pellet shot from a slingshot and spring in the hole, offers keyhole on the described internal cylinder, and, described outer lock core one end is provided with ring-shaped lock dead bolt, is provided with annular groove on the circumferential surface of described outer lock core and internal cylinder, also is provided with stopper slot on the external surface of described internal cylinder, this stopper slot is corresponding with spacer pin or banking stop on the outer lock core, makes internal cylinder move axially a section with respect to outer lock core and moves; Described outer lock core is sleeved in the lock body, and described lock body is provided with alignment pin, and this alignment pin matches with annular groove on the described outer lock core, outer lock core can only be rotated and can not move axially.
Be provided with back-moving spring between described outer lock core and the internal cylinder.
The beneficial effects of the utility model:
1. the utility model modern design, adopt brand-new structure and opening ways, its outer lock core can axially move relatively with internal cylinder, one end of the internal cylinder after moving stretches out outer lock core, the plectrum that is provided with on this end inserts the dead bolt shift fork, the dead bolt shift fork is rotated, the dead bolt shift fork drives the dead bolt motion, thereby reach the purpose of unblanking, perhaps, the annular groove of the internal cylinder after moving axially is corresponding with the annular groove on the outer lock core, makes the ring-shaped lock dead bolt turn-off of outer lock core end, reach the purpose of unblanking, this structure and opening ways have improved the anti-pirate of the open performance of lock core greatly.
2. the anti-pirate of the open of the utility model is effective, its outer lock core and internal cylinder plane contact, and link together by pellet shot from a slingshot and spring, plane contact has reduced the gap between the two, prevents that foreign matter from entering, and realizes a heavily anti-pirate of the open; Outer lock core can dally in fixed cover, and torsional forces information is not provided, and makes the keyless person of unblanking can't judge tram between lock core and the dead bolt driving member, realizes the anti-pirate of the open of two-fold; The key of coupling inserts in the keyhole of internal cylinder, and the height of pellet shot from a slingshot is adjusted, and internal cylinder is consistent with the height of the pellet shot from a slingshot at place, the contacted plane of outer lock core, and internal cylinder axially moves under the effect of key, implements then to unblank, and realizes triple anti-pirate of the open.
3. the utility model scope of application is wide, and the selling market is wide, can be adapted to large-scale industrialized production, has good society and economic benefit.
