Abstract

The utility model relates to a anti-theft lock, in particular to a irregular marble lock and a key of the lock, which comprises a locking head consisting of an outer ring, a lock core, a keyhole, marble grooves and marbles, a lock body consisting of a transmission tablet, a lock tongue and a lock valve, and the key drilled with marble holes. The symmetric marble grooves from the outer ring of the locking head to the lock core are staggered and irregularly arranged, and the staggered irregular arrangement of the marble holes of the key is corresponding to that of the marble grooves of the locking head. The utility model, having the advantages of preventing the master key from unlocking and not increasing the manufacturing cost and not changing the manufacturing technology, is suitable for the transformation and application in hardware lock plants.

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 the key that is drilled with the pellet shot from a slingshot hole thereof are 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 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 a kind of key front view that the utility model proposes.

Fig. 4 is that first kind of B-B of key shown in Figure 3 is to sectional view.

Fig. 5 is that second kind of B-B of key shown in Figure 3 is to sectional view.

A kind of irregular cylinder lock head A-A that Fig. 6 is shown in Figure 2 and foundation the utility model proposes is to sectional view.

Fig. 7 is that the third B-B of key shown in Figure 3 is to sectional view.

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

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 the pellet shot from a slingshot hole thereof are formed.

As Fig. 3, shown in Figure 6, with the irregular alignment of staggering of tapered end 1 outer ring 6 to the bullet groove 8 of lock core 7 symmetries, the irregular alignment of staggering of the pellet shot from a slingshot hole 11 of key 10 and the bullet groove 8 of tapered end 1 is corresponding.

With reference to Fig. 4, Fig. 5, Fig. 7, described key 10 cross sections that are drilled with pellet shot from a slingshot hole 11 are square or selenodont or round.
