Description

Irregular cylinder lock and key thereof
One, technical field
The utility model relates to a kind of theftproof lock, especially a kind of irregular cylinder lock and key thereof.
Two, background technology
The kind of theftproof lock is more, mainly contain mechanical type, combine three kinds of formulas of electronic type or mechano-electronic, mechanical antitheft lock have firm, stable, inexpensive laudatory title, its kind is a lot of, complex structure, technology is loaded down with trivial details, the known mechanical type general theftproof lock comparatively approaching with the utility model is by the outer ring, lock core, keyhole, bullet groove, the tapered end that pellet shot from a slingshot constitutes and by driver blade, dead bolt, lock body that locking-valve constitutes and the key that is drilled with the pellet shot from a slingshot hole thereof are formed, but because its tapered end outer ring is regularly arranged to the bullet groove straight line of lock core symmetry, the pellet shot from a slingshot hole of key is regularly arranged corresponding with the bullet groove straight line of tapered end, so easily opened by existing master key.
Three, summary of the invention
The purpose of this utility model provides a kind of improved theftproof lock, both can prevent to be opened by existing master key, does not increase cost of manufacture again and changes manufacturing process.
For achieving the above object, the utility model comprises: tapered end that is made of outer ring, lock core, keyhole, bullet groove, pellet shot from a slingshot and the lock body that is made of driver blade, dead bolt, locking-valve and be drilled with the pellet shot from a slingshot hole or the key that is provided with is formed, with the irregular alignment of staggering of tapered end outer ring to the bullet groove of lock core symmetry, the irregular alignment of staggering of the pellet shot from a slingshot hole of key and the bullet groove of tapered end is corresponding.
The utility model is owing to only need the irregular alignment and the pellet shot from a slingshot hole of key is corresponding with it of staggering of tapered end outer ring to the bullet groove of lock core symmetry is unblanked so can prevent master key effectively; Simultaneously because do not change the basic structure and the manufacturing process of tapered end, lock body, key, so make still simple.
Four, description of drawings
Concrete structure of the present utility model is provided by the following drawings.
Fig. 1 is known cylinder lock total structure front view.
Fig. 2 is a cylinder lock head schematic diagram shown in Figure 1.
Fig. 3 is according to the first kind of irregular stagger arrangement key of the hole shape front view that the utility model proposes.

Each sign expression in the accompanying drawing:
1. 7. lock cores, 8. bullet groove, 9. keyholes, 10. keys, 11. pellet shot from a slingshot holes, tapered end 2. lock bodies 3. dead bolts 4. lock bodies, 5. locking-valves, 6. outer rings, 12. pellet shot from a slingshot teeth
Below in conjunction with accompanying drawing the utility model is described in further detail.
Five, the specific embodiment
With reference to Fig. 1, Fig. 2, the scheme of the utility model design comprises known, and tapered end 1 that is made of outer ring 6, lock core 7 keyholes 9, bullet groove 8, pellet shot from a slingshot and the lock body 4 that is made of driver blade 2, dead bolt 3, locking-valve 5 and the key that is drilled with pellet shot from a slingshot hole 11 or is provided with pellet shot from a slingshot tooth 12 thereof are formed.
As Fig. 3, shown in Figure 9, according to the irregular stagger arrangement key of first kind of hole shape that the utility model proposes, be with tapered end 1 outer ring 6 to the bullet groove 8 of lock core 7 symmetries in length and breadth to the irregular alignment of staggering, the pellet shot from a slingshot hole 11 of key 10 is corresponding to the irregular alignment of all staggering in length and breadth with the bullet groove 8 of tapered end 1.
As Fig. 4, shown in Figure 10, according to the irregular stagger arrangement key of second kind of hole shape that the utility model proposes, be with the irregular alignment of vertically staggering of tapered end 1 outer ring 6 to the bullet groove 8 of lock core 7 symmetries, the irregular alignment of vertically staggering of the pellet shot from a slingshot hole 11 of key 10 and the bullet groove 8 of tapered end 1 is corresponding.
As Fig. 5, Fig. 6, shown in Figure 11, described first kind, second kind cross section that is drilled with the key 10 in pellet shot from a slingshot hole 11 is square or selenodont or round.
As shown in Figure 7, according to the irregular key of the third yi word pattern profile of tooth that the utility model proposes, be with the irregular alignment of vertically staggering of two-way pellet shot from a slingshot tooth 12 shown in the unidirectional pellet shot from a slingshot tooth 12 of key 10 or the dotted line, same tapered end 1 outer ring 6 to the bullet groove 8 of lock core 7 symmetries in length and breadth to the irregular alignment of staggering.
As shown in figure 12, the cross section of the irregular key of the third yi word pattern profile of tooth is unidirectional flute profile or two-way flute profile.
