The purpose of this utility model is, a kind of novel little, in light weight, safe and reliable vehicle dual-safety anti-theft lock core of volume that has is provided.

The purpose of this utility model realizes by implementing following technical scheme:

The dual-safety anti-theft lock core is made of assemblies such as lock front stall, lock back seat, lock core, dead bolt, spring and pellets shot from a slingshot.The lock front stall is that a core has garden post cavity, external surface is three layers of step-like Cylinder, hypomere ladder garden column diameter is big, garden, stage casing column diameter is placed in the middle, epimere garden column diameter minimum, on stage casing and hypomere garden post jamb, have the pellet shot from a slingshot slotted eye of 4 perforations altogether vertically and down from last, wherein on the post jamb of hypomere garden, have 3 the horizontal direction of wall.In perpendicular perpendicular to the plane that constitutes by garden post central axis and horizontal direction pellet shot from a slingshot slotted eye, epimere garden post jamb is vertically had two relative rectangular notches, this is divided into two sections to notch with epimere garden post jamb, the top of one section wall is from notch therein, and this section wall along the wall horizontal direction to the place, 4 pellet shot from a slingshot hole sites of aliging forms a breach.

The lock back seat is a Cylinder that mates with the lock front stall, its internal chamber wall is three sections cylinder chamber of large, medium and small diameter, its chamber, big footpath wall is harmonious with the stage casing post jamb of lock front stall, wherein chamber, footpath wall is harmonious with the epimere post jamb of lock front stall, the end face of lock back seat has a dead bolt and stretches out opening, the lock front stall is fixed by screw with lock back seat coupling back, forms a garden post lock core body with garden post inner chamber.

Lock core is a Cylinder, its diameter is slightly less than the intracavity diameter of lock front stall, its length is less than the height of lock front stall, the end face of lock core has cross key socket, is cross inner chamber in its cylinder, on the sidewall of lock core cylinder, cross head position at alignment end face cross, have 4 pellet shot from a slingshot slotted eyes from bottom to top, on the pellet shot from a slingshot slotted eye, a location pintle hook lock is equipped with in the upper end of lock core post jamb.Dead bolt is the Cylinder of a tool crown cap, the diameter of this garden post is slightly less than the opening diameter of lock back seat end face, in the cavity that synthesizes by lock front stall and lock back seat, dead bolt is contained in the cavity of lock back seat, lock core is equipped with in its underpart, be set with spring on the dead bolt, pellet shot from a slingshot is contained in the pellet shot from a slingshot notch and by marble spring and locatees.

Of the present utility model being characterised in that: in the cavity that lock front stall and lock back seat form, the dead bolt of suit back-moving spring is housed in the lock core top, the lock core post jamb is provided with the location pintle hook lock, and on the epimere wall of lock front stall, have 2 vertical notches that can accommodate the alignment pin card, and can make this pin card make the horizontal direction breach on the wall that also can lock lock core that slides along this wall.

Advantage of the present utility model is: owing between the forward and backward seat of lock core and lock the common lock structure that is formed by bullet groove and pellet shot from a slingshot is arranged, thereby has a safety of common lock, and the spring that suit on the dead bolt, pin fastening position breach on alignment pin card on the lock core and the lock front stall wall cooperatively interacts, dead bolt is pinned firmly, second road insurance that Here it is increases had both made pellet shot from a slingshot be opened, and was also of no avail.In addition, also have simple in structurely, lock body is little, in light weight, the axle of all rotations can be locked with axle sleeve, or lock all wheel discs such as vehicle steering etc. by fixed support, and can be used for the locking of bicycle such as bicycle, tricycle etc., also can be used for the locking of lathe.

The utility model has following accompanying drawing:

Fig. 1 is in the section of structure of opening for dead bolt

The section of structure that Fig. 2 is in the lock state for dead bolt

Fig. 3 is lock front stall perspective view.

Mark among the figure: 1 is the lock back seat, 2 are the lock front stall, and 3 is lock core, and 4 is dead bolt, 5 is the dead bolt back-moving spring, 6 is the lock core dowel card, and 7,8,9 is bullet groove, and 10 is pellet shot from a slingshot, 11 is screw, 12 pin fastening position breach terminals for lock front stall epimere wall, 13 are lock body top mouth, 14 are the alignment pin draw-in groove mouth on the lock front stall epimere wall.
