Description

Anti-theft magnetic cylinder lock

Technical field

The utility model relates to mechanical cylinder lock.

Background technology

The lockset of prior art mainly contains electronic password lock, Fingerprint Lock, mechanical lock three major types.Wherein mechanical cylinder lock has the characteristics of with low cost, dependable performance and is still most widely used lockset; But it is poor that the shortcoming of standard machinery cylinder lock is a theftproof performance.Minority lawless person in the society often utilizes the characteristics of the easy pirate of the open of mechanical lock, burglary; Some personnel that " suddenly unblank " can open door lock easily, cause resident family uneasy in terror.

Traditional mechanical cylinder lock is to utilize the combination of several pellets shot from a slingshot and the key that is complementary with it and realize opening, and described pellet shot from a slingshot is contained in the pellet shot from a slingshot hole, and the little spring that the compressing pellet shot from a slingshot resets is housed, and can see these pellets shot from a slingshot from lockhole.When normally unblanking, the teeth groove on the key that inserts in the lockhole makes the pellet shot from a slingshot jack-up of correspondence position to bolt no longer flexible lock core can rotate with key and realizes unblanking between flexible lock core and lock body in lock body.The technology of unblanking of so-called " suddenly unblanking " is to determine number number (length) of pellet shot from a slingshot by the feel of stirring in the lockhole after every pellet shot from a slingshot, and uses corresponding unlocking tool, easy lock is opened.

The utility model content

The technical problems to be solved in the utility model is that the defective at prior art exists designs a kind of anti-theft magnetic cylinder lock, its simple in structure, good mechanical property, and anti-pirate of the open dependable performance.

The technical solution of the utility model is, described anti-theft magnetic cylinder lock comprises the rotatable lock core that is contained in the lock body, described lock core and lock body are provided with the corresponding radially pellet shot from a slingshot hole that connects, its design feature is, described radially pellet shot from a slingshot hole is symmetricly set on the both sides of lock core hole in pairs, and every pair radially is equipped with at least two permanent magnet pellets shot from a slingshot respectively in the pellet shot from a slingshot hole and inboard pellet shot from a slingshot is identical towards the pole polarity of lock core hole one end.

Below make and further specifying.

Referring to Fig. 1 and Fig. 2, the utility model comprises the rotatable lock core 2 that is contained in the lock body 1, described lock core 2 and lock body 1 are provided with the corresponding radially pellet shot from a slingshot hole that connects, its design feature is, described radially pellet shot from a slingshot hole 3,31 are symmetricly set on the both sides of lock core hole 4 in pairs (as being provided with four pairs of radially pellet shot from a slingshot holes among Fig. 1 altogether, every pair radially the pellet shot from a slingshot hole respectively by being positioned on the lock core hole 4 shown in Figure 1, following both sides relative two are pellet shot from a slingshot hole 3 radially, 31 form), every pair of pellet shot from a slingshot hole 3 radially, be equipped with two to four permanent magnet pellets shot from a slingshot 5 in 31 respectively, 6 or 51,61 and inboard permanent magnet pellet shot from a slingshot 6,61 is identical towards the pole polarity of lock core hole 4 one ends.

Design principle of the present utility model is, as depicted in figs. 1 and 2, because it is same to the pole polarity identical (N is extremely relative in as Fig. 1) of two relative in the pellet shot from a slingshot hole 3 radially inboard permanent magnet pellets shot from a slingshot 6,61 towards lock core hole 4 one ends, principle according to the permanent magnet homopolar-repulsion, described permanent magnet pellet shot from a slingshot 6,61 is arranged in corresponding pellet shot from a slingshot hole (as shown in Figure 1 and Figure 2) because of repelling mutually, play with the prior art cylinder lock in the identical dowel action of pellet shot from a slingshot, lock core 2 can not be rotated; And for example shown in Figure 3, after magnetic conduction key 7 (as the steel key) inserts in the lock core hole 4, it has blocked the magnetic field effect of above-mentioned mutual repulsion, and under magneticaction, both sides permanent magnet pellet shot from a slingshot 6,61 is sucked in the key teeth groove, removed thus the locking of lock core 2 made it to rotate with key 7 and realized unblanking.This magnetic bullet lock construction makes existing " suddenly unblanking " technology can't open lock of the present utility model at all, and its anti-pirate of the open performance is very reliable.

Two pairs of permanent magnet pellets shot from a slingshot as shown in Figure 4 can be set in the same radial section position of lock core 2 and lock body 1.

Also can with every pair radially the permanent magnet pellet shot from a slingshot in the side opening in pellet shot from a slingshot hole be fixedly mounted in this side opening.

Also the pellet shot from a slingshot in the pellet shot from a slingshot hole can be designed to the structure of the alternate setting of pellet shot from a slingshot group that back-moving spring is housed of permanent magnet pellet shot from a slingshot shown in Figure 5 and prior art.

As known from the above, the utility model is an anti-theft magnetic cylinder lock, has the characteristics of simple in structure, good mechanical property, anti-pirate of the open dependable performance.It can be widely used in various mechanical cylinder locks, as door lock (latch), padlock, drawer-lock, Vehicle lock etc., also can form existing lockset transformation.
