Abstract

The invention relates to a burglarproof lock cylinder and a key matched with the same. The burglarproof lock cylinder and the key matched with the same comprise a lock cylinder body, a lock body, springs, upper marbles, lower marbles and a key body, wherein a key hole is positioned in the lock cylinder on the side faces of marble channels; a magnet perpendicular to the marble channels is arranged on the sides of the marble channels; a steel ball is arranged at the lower end of each lower marble in the corresponding marble channel; a positioning pin hole is formed in the lock cylinder; a positioning pin is arranged on the key; protrusions on the key are positioned at the side part of the key body of the key. The burglarproof lock cylinder and the key matched with the same disclosed by the invention have the advantages of high reliability, high simplicity in processing, low cost, easiness for use, long service life of products and capability of effectively preventing multiple unlocking techniques.

Description

A kind of anti-theft lock and associated key
Technical field
The present invention relates to a kind of anti-theft lock and associated key.
Background technology
The lock core major part of current production be keyhole and hoodle passage at grade, hoodle part is positioned at keyhole, exposes to the open air within naked eyes observable scope.And this part hoodle does not have estrangement each other.When key inserts below hoodle: key spinous process arrives below hoodle predetermined separately by the mode of jack-up hoodle, the mode outwards ejected by key spinous process prize hoodle realizes unblanking.This kind of lockset long history, with low cost, but safety is very low.Wanting to improve security performance, can only be make a price reduction by the probability of technology unlocking with the method reducing keyhole length by increasing hoodle number.Existing tinfoil class on present society, singly hook class, rock class, hit key class and continue to stir hoodle class etc. everywhere technology unlocking method successfully can realize the technology unlocking to this kind of lockset.Some technology unlocking method is even very easy to learn.Bring uneasy and potential safety hazard greatly to society and each family.In addition because the key spinous process of this kind of lock and hoodle are rigid friction.After long-time use, key spinous process and hoodle cause wearing and tearing mutually.Unblank to become difficulty, life of product is limited.
Summary of the invention
Object of the present invention is just to provide that a kind of structure is simple, theftproof performance is strong, easy to use and a kind of anti-theft lock that cost of production is low and associated key.
Technical scheme of the present invention is achieved in that a kind of anti-theft lock and associated key, comprise lock core, lock body, spring, upper hoodle, lower pellet and key, keyhole is positioned on the lock core of hoodle passage side, be provided with perpendicular magnet in the side of hoodle passage, the lower end of the lower pellet in hoodle passage is provided with steel ball.
The another kind of technical scheme of the present invention is: on lock core, be provided with dowel hole.
The present invention more another kind of technical scheme is: be provided with alignment pin on the key.
The present invention more another kind of technical scheme is: spinous process is on the key positioned at the key body side of key.
Advantage of the present invention is: structure is simple, and cost of production is low, use safety, and theftproof performance is strong.

Fig. 2 is that sectional structure schematic diagram is looked on Fig. 1 right side;
Fig. 3 is the structural representation of lock core;
Fig. 4 is the structural representation of key.
Detailed description of the invention:
As shown in Figure 1,2,3, 4, a kind of anti-theft lock and associated key, comprise lock core 1, lock body 2, spring 12, upper hoodle 10, lower pellet 11 and key 3, keyhole 4 is positioned on the lock core 1 of hoodle passage 9 side, be provided with perpendicular magnet 8 in the side of hoodle passage 9, the lower end of the lower pellet 11 in hoodle passage 9 is provided with steel ball 13.
Another embodiment of the invention is: as shown in Figure 2,3, and lock core 1 is provided with dowel hole 7.
More another kind of embodiment of the present invention is: as shown in Figure 4, and key 3 is provided with alignment pin 6.
Further embodiment of the present invention is: as shown in Figure 4, and the spinous process 5 on key 3 is positioned at the key body side of key 3.
When the present invention works, as shown in Figure 1,2,3, 4, after when unblanking, key 3 inserts keyhole 4, the alignment pin 6 on key 3 is inserted in the dowel hole 7 on lock core 1.Rotate key 3, key 3 is along alignment pin 6 unitary rotation.Key spinous process 5 inserts the below of steel ball 13.Steel ball 13 is outwards ejected by key spinous process 5, is outwards ejected by below hoodle 11.Because the thickness of key spinous process 5 part corresponding from lower pellet 11 is different, below hoodle 11 is each different by the length outwards ejected.Make the upper limb of the below hoodle 11 of different length can be in the same plane with the outer rim of lock core 1.Connection between lock core 1 and lock body 2 is disconnected, and lock core 1 is separated with lock body 2.Continue to rotate key 3, lock core 1 is driven by key 3 and rotates in lock body 2, thus realizes unlocking function.
Rotate backward key 3, key spinous process 5 exits for 13 from steel ball, and lock core 1 is oppositely driven by key 3, and the rear lock core 1 that puts in place aligns with hoodle passage 9, and spring 12 is by top hoodle 10 part press-in hoodle passage 9.Upper hoodle 10 is between lock core 1 and lock body 2, and lock core 1 combines with lock body 2.Complete the action of locking.
When meeting tinfoil class, when rocking class and continue to stir hoodle class technology unlocking.Because lower pellet 11 is hidden in hoodle passage 9, due to the stop of the estrangement between hoodle passage 9.Unlocking tool can not enter the below of steel ball 13, more can not carry out pull motion.Can not produce effective friction by dual lock instrument by free rolling steel ball 13.Thus prevent this type of technology unlocking.
When running into single hook class and hitting key class technology unlocking.Due to top hoodle 10 all the time attract by the magnet 8 of side-lower, upper hoodle 10 is close to the side of the hoodle passage 9 at magnet 8 place.Upper hoodle 10 can not drop on the necessary opposite side of this two classes technology unlocking.Thus prevent this type of technology unlocking.
