The prior art that is close most with the utility model is a kind of tapered end of magnetic padlock.Its structure has: lock core, lock tube, permanent magnet pellet shot from a slingshot and the magnetic key that matches with this tapered end.In cylindrical lock tube, have cylindrical hole, be used for the lock core of packing into along centerline direction.Get through some apertures perpendicular to the direction of center line on lock tube, the axis of these apertures can be parallel to each other, and can also be the different surface beeline that is in certain angle, but they all intersect with the center line of lock tube and be vertical.These apertures are that diametric(al) along lock tube penetrates in other words.Because these apertures are used for installing pellet shot from a slingshot, so be called " the pellet shot from a slingshot aperture is installed ".Said pellet shot from a slingshot is a piece permanent magnet, so be called " permanent magnet pellet shot from a slingshot ".Lock core is that certain thickness drum is arranged, and the cylindrical hole of its external diameter and lock tube adapts, and the key bar diameter of its internal diameter and magnetic key adapts.On lock core, be equipped with the duck eye that several do not penetrate from the external surface of cylindrical lock core to the lock core axis direction, because duck eye does not penetrate the wall of cylinder, so be referred to as " end duck eye is arranged ".Have the number of end duck eye identical with the installation pellet shot from a slingshot aperture bar number on the lock tube, when its position was packed lock tube at lock core, it was corresponding one by one with every the pellet shot from a slingshot aperture to be installed.During installation, lock core is inserted lock tube, the pellet shot from a slingshot aperture is installed one to one and is had under the not alignment situation of end duck eye and put into magnetic bullet, with spacing rivet the pellet shot from a slingshot aperture will be installed and seal, promptly shut the permanent magnet pellet shot from a slingshot.As seen concrete structure joins Fig. 1 and Fig. 2.

Fig. 1 is the lock head structure schematic diagram of existing magnetic padlock.

Fig. 2 is the unblank magnetic key schematic diagram of usefulness of existing magnetic padlock.

In Fig. 1,1 is lock tube, and 2 is lock core, and 3 is the fixed permanent magnet pellet shot from a slingshot, and they are shut motionless by lock core 2 and spacing rivet in lock tube.4 is movable permanent magnet pellet shot from a slingshot, though their limited when mounted rivets are sealed, but when the pellet shot from a slingshot aperture being installed and having that duck eye aligns at the end, because magnetic force permanent magnet pellet shot from a slingshot can fall in the end duck eye, so the space appears between spacing rivet and permanent magnet pellet shot from a slingshot, the height in space with have the dark end of end duck eye identical.Just because this part permanent magnet pellet shot from a slingshot can displacement, thus be called " movable permanent magnet pellet shot from a slingshot ", and another part permanent magnet pellet shot from a slingshot not with have end duck eye corresponding, quilt is shut can not displacement, is called " fixed permanent magnet pellet shot from a slingshot ".Among Fig. 1,5 for the pellet shot from a slingshot aperture is installed, and opens on lock tube 1, and 6 for there being end duck eye, opens on lock core 2.Provided five among Fig. 1 and pellet shot from a slingshot aperture 5 and corresponding five be installed end duck eye 6 is arranged, five permanent magnet pellets shot from a slingshot that end duck eye 6 should be arranged have been movable permanent magnet pellet shot from a slingshot 4, and in addition half bar five of packing in the pellet shot from a slingshot aperture are installed is fixed permanent magnet pellets shot from a slingshot 3.Among Fig. 1,7 is spacing rivet.Every movable one to one permanent magnet pellet shot from a slingshot 4 and fixed permanent magnet pellet shot from a slingshot 3 of installing in the pellet shot from a slingshot aperture 5 is that opposite pole is packed into relatively and installed in the pellet shot from a slingshot aperture 5, and when not having external magnetic field when magnetic key unlocking (useless), the two is corresponding one by one attraction.

Among Fig. 2,8 is the magnetic the shank of the key, and 9 is the magnetic key bar, and 10 is the key permanent magnets, and 11 is big envelope.Magnetic key bar 9 is an elongated cylindrical, its diameter is identical with the internal diameter and the length of the lock core 2 that matches with length, several key permanent magnets 10 of fixed installation in it, concrete number is identical with the number that end duck eye 6 is arranged on the lock core 2 that matches (number of movable permanent magnet pellet shot from a slingshot 4).Seal with big envelope 11 outside of magnetic key bar 9.Distance between the pole orientation of key permanent magnets 10 and each permanent magnets, with having end duck eye 6 corresponding one by one on the lock core 2 that matches, and with relative installation of like pole of movable permanent magnet pellet shot from a slingshot 4.The magnetic key repels movable permanent magnet pellet shot from a slingshot 4 is corresponding one by one mutually as external magnetic field (when using the magnetic key unlocking), makes movable permanent magnet pellet shot from a slingshot 4 leave end duck eye 6, and lock core 2 and related dialing spring rotate under the magnetic key drives, and can unblank.

The tapered end of the magnetic padlock of prior art no longer is to unblank with mechanical means, thus have easy to use, not fragile, secret hold depth advantages of higher.But prior art also has many shortcomings, analogy, because fixed permanent magnet pellet shot from a slingshot 3 and movable permanent magnet pellet shot from a slingshot 4 distances are big, magnetic attraction is little mutually, and movable permanent magnet pellet shot from a slingshot 4 is difficult for whole adhesives when locking, can cause mechanicalness to damage; Because movably permanent magnet pellet shot from a slingshot 4 mutual magnetic force are more or less the same with movable permanent magnet pellet shot from a slingshot 4 and 3 magnetic force of fixed permanent magnet pellet shot from a slingshot, thereby movably permanent magnet pellet shot from a slingshot 4 disturbs greatly each other, and the difficulty that playbacks when locking causes magnetic padlock not handy; Owing to use ferromagnetic material (as sintered neodymium iron boron material), use wire-electrode cutting and processing method to make the permanent magnet pellet shot from a slingshot, not only processing difficulties has also increased cost.

The utility model is the deficiency that overcomes existing Magnetic lock, by increasing the wall thickness of lock core, change the installation position of permanent magnet pellet shot from a slingshot, install methods such as ferrimagnet pellet shot from a slingshot additional, reach and reduce movable permanent magnet pellet shot from a slingshot 4 with distance between the fixed permanent magnet pellet shot from a slingshot 3, thereby increase the gravitation between them, reduce the purposes that movable permanent magnet pellet shot from a slingshot 4 disturbs each other, and can use permanent-magnet material easy to process and reduce cost.

The Magnetic lock of reflection type magnetic padlock head of the present utility model and prior art is roughly the same, is made of lock tube, lock core, permanent magnet pellet shot from a slingshot and the magnetic key that matches with tapered end.The cylindrical shape lock core can insert in the cylindrical hole in the lock tube, its wall is thicker than prior art, it is to leave inwards from external surface along the radial direction of lock core that several that have on it have end duck eye, per two duck eyes be on same diameter one to one, and the opposite pole permanent magnet pellet shot from a slingshot of relatively respectively packing into is arranged in the end duck eye two of correspondence, the length of permanent magnet pellet shot from a slingshot is less than the degree of depth that end duck eye is arranged, the permanent magnet pellet shot from a slingshot of half number is fixed, as the fixed permanent magnet pellet shot from a slingshot, the permanent magnet pellet shot from a slingshot of second half number is as movable permanent magnet pellet shot from a slingshot, opened some at the center line of the vertical lock tube in lock tube upper edge the pellet shot from a slingshot aperture has been installed, the installation pellet shot from a slingshot apertures different with prior art are not to open along diameter, but open along the radius of lock tube, the number that the pellet shot from a slingshot aperture is installed and position have the end duck eye number identical with what movable permanent magnet pellet shot from a slingshot was housed, the position correspondence.The ferrimagnet pellet shot from a slingshot of packing in the pellet shot from a slingshot aperture is installed is shut with spacing rivet again, and the length of spacing rivet is identical with the length that the pellet shot from a slingshot aperture is installed with the length sum of ferrimagnet pellet shot from a slingshot.

For clear expression structure of the present utility model, provide Fig. 3.

Fig. 3 is the structural representation of reflection type magnetic padlock head.

In Fig. 3, the meaning of label 1～7 is identical with Fig. 1 of prior art, and 12 are the ferrimagnet pellet shot from a slingshot in the installation pellet shot from a slingshot aperture 5 of packing into, and 13 is that ferrimagnet pellet shot from a slingshot 12 is inhaled into the space of leaving between end duck eye 6 backs and the spacing rivet 7.When using the magnetic key unlocking that matches with it, like pole repels mutually, and movable permanent magnet pellet shot from a slingshot 4 is moved outside end duck eye 6 is arranged, and ferrimagnet pellet shot from a slingshot 12 is all released end duck eye 6, and lock core 2 can rotate.The permanent magnet pellet shot from a slingshot can use the permanent magnet of compression moulding material.

The utility model can be implemented like this: lock core 2 is inserted in the cylindrical hole of lock tube 1, punch to centerline direction from the external surface of lock tube 1 in position by prior design, these holes are exactly pellet shot from a slingshot aperture 5 to be installed and corresponding end duck eye 6 to be arranged, the punching degree of depth be as the criterion not penetrate lock core 2 (analogy leaves the thickness of 1mm, and this thickness is at the bottom of the hole of end duck eye 6).Take out lock core 2, the relative opposite side of end duck eye 6 leaves second half number that end duck eye 6 arranged with having of having left, and these have end duck eye 6 fixed permanent magnet pellet shot from a slingshot 3 backs of packing into fixing.The movable permanent magnet pellet shot from a slingshot 4 of again lock core 2 being packed into inserts in the cylindrical hole of lock tube 1.Pellet shot from a slingshot aperture 5 is being installed and is being had end duck eye 6 not have under the alignment case, ferrimagnet pellet shot from a slingshot 12 is being packed into install in the pellet shot from a slingshot aperture 5, with spacing rivet 7 tights shut.Rotary locking cylinder 2 is to a certain position, and ferrimagnet pellet shot from a slingshot 12 can fall into automatically and install the having in the end duck eye 6 of movable permanent magnet pellet shot from a slingshot 4, and lock core 2 can not be rotated by 12 lockings of ferrimagnet pellet shot from a slingshot again.During installation, note the direction relations of movable permanent magnet pellet shot from a slingshot 4, fixed permanent magnet pellet shot from a slingshot 3 and key permanent magnets 10 each magnetic pole.

Owing to there is the end of end duck eye 6 can stay very thinly, the distance of therefore movable permanent magnet pellet shot from a slingshot 4 and fixed permanent magnet pellet shot from a slingshot 3 is satisfying closer from getting, and attraction is big, and when the lock lock, all adhesives easily are difficult for the mechanicalness damage; Can also reduce to make the difficulty of permanent magnet pellet shot from a slingshot with the more weak compression moulding material permanent magnet of magnetic, cost greatly can reduce cost; Because attraction is big between corresponding permanent magnet pellet shot from a slingshot, lock core 2 wall thickness, ferrimagnet pellet shot from a slingshot 12 phase mutual edge distances become big, thereby have reduced the phase mutual interference between the movable permanent magnet 4, make ferrimagnet pellet shot from a slingshot 12 be easy to playback; Owing to,, make lock durable so the mechanical strength of pellet shot from a slingshot increases by 12 lockings of ferrimagnet pellet shot from a slingshot.
