Description

Magnetic core pellet shot from a slingshot combination lock

The utility model relates to mechanical anti-theft lock, particularly has the mechanical anti-theft lock of magnetic core and pellet shot from a slingshot combination.

Now, commercially available mechanical anti-theft lock has the reliability and the intensity of quality, but style is various, and structure mostly is similar.And have the lock of magnet configurations, and magnetic core is stuck in the hole between lock housing and the lock core more, because the molecular structure of magnetic core be very regular the two poles of the earth arrangement, and is brittle state, thereby is subjected to the shearing force of external force slightly, just is easy to embrittlement.

The purpose of this utility model provides the lock of a kind of magnetic core and pellet shot from a slingshot tectonic association, and magnetic core directly is not stuck between lock housing and the lock core, does not bear any shearing force.

Technical solution of the present utility model is the lock housing at the existing machinery lock, lock core, the hole that is no less than a row that intercommunication is mutually arranged between lock housing and the lock core, have in the hole on the basis of pellet shot from a slingshot and spring, the utility model particularly has a row hole on a face of key, magnetic core is arranged in the hole, arrange in the hole of intercommunication at one of lock housing and lock core, the blind hole of the Kong Weiyi end sealing of its lock core, magnetic core is arranged in the hole, spring and pellet shot from a slingshot are arranged in the hole of lock housing, and the two diameter of the hole of lock core and the magnetic core all diameter than the hole of lock housing is big.

Of the present utility model being locked in when not inserting key, the pellet shot from a slingshot in the lock housing are subjected to be pushed into the position between lock housing and the lock core under the effect of spring force.At this moment, pellet shot from a slingshot pushes magnetic core in the hole bottom of sealing one end again, thereby lock core can not rotate, and locks locked.After key inserts lock core, magnetic core in the key and the state that is in mutual repulsion mutually after magnetic core in the lock core aligns, under the effect of repulsion, magnetic core in the lock core overcomes the bottom position that spring force leaves the hole, enter into the junction of lock core and lock housing in the pushing pellet shot from a slingshot, because the diameter of lock core and magnetic core is bigger than the diameter in the hole of lock housing, so the magnetic core of lock core only can enter till lock core and the lock housing joint, therefore lock core can rotate, and lock is opened.Hole in the lock core of the present utility model is sealing a side of contact key, and like this, no matter the magnetic core in the hole of lock core is a side who contacts key, or a side of contact lock housing, and the magnetic core of lock core can not run into any shearing force.And magnetic core on the key is to ensconce in the hole, that that is to say that magnetic core only can be by near coal-mine and extraneous the contact, because when key inserts in the lock, a near coal-mine Founder is to a side of the magnetic core of lock core, and the side that lock core contacts with key is sealing side, so during the rotation of key, magnetic core on the key can not be subjected to any shearing force.The utility model is owing to being the lock that refills magnetic core on the basis of mechanical lock, so the utility model possesses the function that mechanical lock is arranged simultaneously.

The utility model is the combination lock with a kind of magnetic core and mechanical billiard Lock structure, has the reliability and the intensity of mechanical cylinder lock, and the good confidentiality of magnetic core lock is arranged again.Behind these two kinds of textural associations, key spoon amount can reach more than 100,000 times.The utility model adopts spring force to promote pellet shot from a slingshot, promotes magnetic core by pellet shot from a slingshot again and resets, and this structure resets with the magnetic force of existing magnet lock and compares, and more not being afraid of dust and metal particle influences the lockset function.It is back and forth movable that magnetic core of the present utility model is only limit in an end blind bore of lock core, and stroke is short, and flexible movements are reliable, and are not subjected to the influence of lock housing size, and processing performance is good.

The utility model has the advantages that the lock with magnetic core and pellet shot from a slingshot tectonic association, magnetic core directly is not stuck between lock housing and the lock core, does not bear any shearing force.

Below in conjunction with accompanying drawing embodiment of the present utility model is described:

Fig. 1 organigram of the present utility model.

According to shown in Figure 1, the utility model is on the basis of existing machinery lock, that is to say the hole that is no less than a row that intercommunication is mutually arranged between lock housing 2, lock core 3, lock housing and lock core, have in the hole on the basis of pellet shot from a slingshot 6, spring 7, the utility model has a row hole on a face of key 1, magnetic core 4 is arranged in the hole, but in a round of lock housing 2 and the intercommunication of lock core 3, the blind hole of the Kong Weiyi end sealing of its lock core 3, magnetic core 5 is arranged in the hole, spring 7 and pellet shot from a slingshot 6 are arranged in the hole of lock housing 2, and the diameter of the hole of lock core 3 and magnetic core 5 is bigger than the diameter in the hole of lock housing 2.After key of the present utility model inserted lock core 3, the magnetic core 4 on the key 1 and the magnetic core 5 in the lock core 3 were in the position of magnetic pole of identical mutual repulsion.

Claims (2)

1, magnetic core pellet shot from a slingshot combination lock, comprise lock housing (2), lock core (3), the hole that is no less than a row that intercommunication is mutually arranged between lock housing (2) and the lock core (3), pellet shot from a slingshot (6) is arranged in the hole, spring (7), it is characterized in that on a face of key (1), having a row hole, magnetic core (4) is arranged in the hole, arrange in the hole of intercommunication at lock housing (2) and one of lock core (3), the blind hole of the Kong Weiyi of its lock core (3) end sealing has magnetic core (5) in the hole, spring (7) and pellet shot from a slingshot (6) are arranged in the hole of lock housing (2), and the hole of lock core (3) and the two diameter of magnetic core (4) all diameter than the hole of lock housing (2) are big.
