Description
Technical field: the utility model relates to a kind of pin tumbler lock, relates in particular to a kind of pin tumbler lock lock core.
Background technology: well-known, the lock core of traditional pin tumbler lock generally by core print seat, be located at a pellet shot from a slingshot mandrel that has keyhole in this core print seat, many springs and a plurality of pellet shot from a slingshot that is located in this core print seat constitutes; Though the lock core of traditional structure is fairly simple, is destroyed by force and opens by special tools such as crowbar, electric drills easily, safety is relatively poor.
Summary of the invention: at the above-mentioned defective that exists in the prior art, the utility model aims to provide a kind of being difficult for by the Prying-resistant and drilling-resistant combined lock core of special tools such as crowbar, electric drill destruction.
To achieve these goals, the utility model by the following technical solutions: it comprises core print seat, is located at the pellet shot from a slingshot mandrel in this core print seat; Described pellet shot from a slingshot mandrel is combined by at least two pellet shot from a slingshot axles, is provided with locating slot on the external cylindrical surface of each pellet shot from a slingshot axle, and the alignment pin that is individually fixed in the core print seat inserts in the corresponding locating slot separately; The end face of innermost that root pellet shot from a slingshot axle is fixed with plectrum.
Be provided with the sheet that skids of band keyhole between adjacent described pellet shot from a slingshot axle, the back side of the sheet that respectively skids is provided with positioning pit; At each pellet shot from a slingshot axial plane the end face of positioning pit is provided with the place kick suitable with this positioning pit, this place kick is pressed in the positioning pit by the retainer spring that is located in the pellet shot from a slingshot axle.
Compared with the prior art, the utility model is owing to adopted technique scheme, on the basis of traditional structure, changed original monolithic pellet shot from a slingshot mandrel into constitute fabricated structure by many pellet shot from a slingshot axles, even if therefore outmost that root pellet shot from a slingshot axle suffers damage of external force, innermost pellet shot from a slingshot axle also can be kept perfectly; Improved the safety of door lock effectively.In addition, owing to be provided with the sheet that skids between adjacent pellet shot from a slingshot axle, even if outmost that root pellet shot from a slingshot axle is destroyed by instruments such as electric drills, it is destroyed that this sheet that skids also can stop other pellet shot from a slingshot axle to continue effectively, the safety that has further improved door lock.
Description of drawings:
Fig. 1 is a structural representation of the present utility model;
Fig. 2 is the A-A sectional view among Fig. 1.
Among the figure: pellet shot from a slingshot axles 3 pellet shot from a slingshot axle 5 plectrums 6 locating slots 7 alignment pins 8 retainer springs 9 place kick 10 positioning pits 11 keyholes 12 in the sheet 4 that skid in the middle of the outer pellet shot from a slingshot axle 2 of core print seat 1
The specific embodiment: the utility model is described in further detail below in conjunction with accompanying drawing and specific embodiment:
In Fig. 1～2, be provided with axis hole in the core print seat 1, be provided with outer pellet shot from a slingshot axle 2, middle pellet shot from a slingshot axle 3 and interior pellet shot from a slingshot axle 5 in this axis hole from left to right successively, keyhole 12 runs through each described pellet shot from a slingshot axle along axis direction; The periphery of above-mentioned each pellet shot from a slingshot axle is provided with some pellets shot from a slingshot hole, and the position corresponding to each described pellet shot from a slingshot hole in the core print seat 1 is provided with pellet shot from a slingshot, and described each pellet shot from a slingshot heads in the corresponding pellet shot from a slingshot hole by the some springs that are located in the core print seat 1 respectively; The external cylindrical surface of each pellet shot from a slingshot axle is provided with locating slot 7, and the alignment pin 8 that is individually fixed in the core print seat 1 inserts in the corresponding locating slot 7 separately; The right side of interior pellet shot from a slingshot axle 5 is fixed with plectrum 6.As can be seen from Figure 1: even if the pellet shot from a slingshot of outer pellet shot from a slingshot axle 2 suffer the destruction by force of external force and lost efficacy, can not open door lock; Because after the pellet shot from a slingshot of outer pellet shot from a slingshot axle 2 was destroyed, whole outer pellet shot from a slingshot axle 2 still was stuck in the axis hole, and middle pellet shot from a slingshot axle 3 and interior pellet shot from a slingshot axle 5 are not destroyed.
In order to prevent to utilize electric drill to destroy the pellet shot from a slingshot mandrel, be equipped with the sheet 4 that skids of band keyhole 12 outside between pellet shot from a slingshot axle 2 and the middle pellet shot from a slingshot axle 3 and between middle pellet shot from a slingshot axle 3 and the interior pellet shot from a slingshot axle 5, the right side of the sheet 4 that respectively skids is equipped with positioning pit 11; Position in the left side of middle pellet shot from a slingshot axle 3 and interior pellet shot from a slingshot axle 5 corresponding to positioning pit 11 is equipped with spring eye, is provided with place kick 10 and retainer spring 9 in each spring eye; Place kick 10 is pressed in the corresponding positioning pit 11 by retainer spring 9, thereby plays the corresponding effect in keyhole 12 positions on keyhole 12 and middle pellet shot from a slingshot axle 3, the interior pellet shot from a slingshot axle 5 on the sheet 4 of determining to skid.As can be seen from Figure 1: even if outer pellet shot from a slingshot axle 2 is destroyed by electric drill, but sheet 4 and middle pellet shot from a slingshot axle 3 coaxial lines owing to skid, therefore touch when skidding sheet 4 when drill bit, this sheet that skids just rotates simultaneously, skids with drill bit, thereby can avoid centre pellet shot from a slingshot axle 3, interior pellet shot from a slingshot axle 5 to be destroyed by drill bit.
