Abstract
The utility model relates to a double-diameter cylinder lock core that is suitable for being installed in any kind of mechanical lock. The utility model is composed of a lock core body, a lock core, a spring, common cylinders, double-diameter cylinders, a key holder and a key. When a lock is unlocked, the key is inserted into the key holder, the key holder is pushed upwards to tightly contact the lock core, holes on the key match with the double-diameter cylinders, and all the common cylinders are just pushed out of the lock core by the double-diameter cylinders; at this time, the key holder is rotated to drive and unlock the lock core. The lock provided with the lock core has the advantage of high security, and the key is difficult to imitate; the lock provided with the lock core can be prevented from being prized and smashed; no matter who, no matter how much time is cost, and no matter which technical method is used, the lock can not be unlocked without the key matching with the original lock core.
Description
The utility model relates to a kind of mechanical lock pellet shot from a slingshot core, specially refers to a kind of two footpaths pellet shot from a slingshot core of being furnished with special key and key holder.
Pellet shot from a slingshot core marble amount in the existing cylinder lock is few, pellet shot from a slingshot displacement is also short, cause the mutual difference of shape of key between the different locks little, sometimes even identical, and directly unblank with the key rotation, the human master key that technology is good when unblanking is constantly aligned the insertion position of key, just can open this cylinder lock in a short period of time.
The purpose of this utility model is key to be completely enclosed within the core in the moment of unblanking for existing all kinds of mechanical locks provide a kind of, and the external world can not handle the safe core of key.
In brief, two footpath pellet shot from a slingshot core is made up of core body, lock core, spring, common spring, two footpaths pellet shot from a slingshot, key holder and key.Common spring is in the same place core body and lock core card during lock-bit.Shift the position onto on when unblanking key being inserted after the key holder, the length of the depth of hole and two footpaths pellet shot from a slingshot match and make whole common spring just be ejected lock core on the key, and with the pop-jump movable lock core of key, core is opened.
Two footpaths pellet shot from a slingshot core of making according to the utility model has following advantage, and the possibility that key repeats is very little, and anyone does not imagine to open this core with technical method, and simplicity of design firmly is fit to be installed in the existing all kinds of mechanical locks.
Fig. 1 is two footpaths pellet shot from a slingshot core cut-away views.
Fig. 2 is the positive diagrammatic sketch of key.
Referring now to Fig. 1, Fig. 2 is elaborated the utility model.Coding (1) indication core body, coding (2) indication lock core, the holder of coding (6) indication key, coding (10) indication hole, the two footpath of coding (11) indication through hole, coding (12) indicating pass through hole, lock core (2) is installed in the cavity top of core body (1), and it can rotate when unblanking.Key holder (6) is installed in the cavity bottom of core body (1), and it can move up and down, and can drive lock core (2) when unblanking again and rotate.Be arranged with many holes (10) on the core body (1), be arranged with many two footpaths through hole (11) on the lock core (2), be arranged with many through holes (12) in the key holder (6), hole (10), two footpaths through holes (11) and through hole (12) correspondence up and down communicate.
Coding (3) indication spring, coding (4) indication common spring, the two footpath of coding (5) indication pellets shot from a slingshot, two footpaths pellets shot from a slingshot (5) are installed in two footpath through holes (11), and spring (3) and common spring (4) are by being installed in the hole (10) in proper order up and down.Because how much all short than the length of two footpaths through holes (11) thicker part branch the length that all two footpaths pellet shot from a slingshot (5) thicker parts divide is, so whole common spring (4) all have the part of varying length to extend in two footpath through holes (11) under the pressure of spring (3), another part is then stayed in the hole (10), common spring (4) is stuck core body (1) and lock core (2) as a result, lock core (2) can not rotate in core body (1), and two footpaths pellet shot from a slingshot core of this moment is a lock-bit.
Coding (13) indication slot, coding (14) indication hole, coding (15) is indicated soft band, coding (16) indication push-and-pull ring, coding (8) indication socket, socket (8) is opened on the cavity lower wall of core body (1), and slot (13) is opened the middle part in key holder (6).Socket during the core lock-bit (8) and slot (13) correspondence communicate.Be arranged with many holes (14) on the key (7), have a soft band (15) connecting a push-and-pull ring (16) on its limit.When wanting to open two footpaths pellet shot from a slingshot core, key (7) is pushed in the slot (13) through socket (8), hole (14) and through hole (12) all align are communicated with push-and-pull ring (16).Promote key holder (6) drive key (7) and move up, soft band (15) is crooked thereupon to be moved, and the bottom of key holder simultaneously (6) is sealed socket (8) gradually.When the lower plane of the last plane of key holder (6) and lock core (2) is adjacent to, the thin end of two footpaths pellets shot from a slingshot (5) has passed through hole (12) and has entered into hole (14), because the depth of each hole (14) all is complementary with its pairing two directly length of pellets shot from a slingshot (5), so all two footpath pellets shot from a slingshot (5) this moments also move on to the last plane that reaches lock core (2) on, the whole common spring of result (4) are just ejected two footpaths through hole (11) by the butt end of two footpath pellets shot from a slingshot (5), key holder this moment (6) drives lock core (2), and two footpaths pellet shot from a slingshot core is opened.
Claims (4)
1, a kind of two footpaths cylinder lock pericardium is drawn together core body (1), lock core (2), spring (3), common spring (4), it is characterized in that also comprising accepting key (7) normal impact and increasing with promotion two footpaths pellets shot from a slingshot (5) of displacement, can be core body (1) in arbitrarily crooked and mobile key (7), increased the vertical mobile and fixedly key (7) and the key holder (6) of sealing socket (8) in the cavity of core body (1).
2, according to claim 1 described two footpaths pellet shot from a slingshot core, it is characterized in that two footpath pellets shot from a slingshot (5) are the cylinders that many hypomeres are thin, epimere thick, epimere length has nothing in common with each other.
3,, it is characterized in that being arranged with many through holes (12) in the key holder (6), there is a slot (13) centre according to the described two footpaths of claim 1 pellet shot from a slingshot cores.
4,, it is characterized in that being arranged with on the key (7) on hole (14) that many depths have nothing in common with each other, the limit and have a soft band (15) to connect a push-and-pull ring (16) according to the described two footpaths of claim 1 pellet shot from a slingshot cores.
