Abstract
The utility model discloses a drawing-away type column surface magnetic coded lock core and a key, which is characterized in that a key hole inside the lock core is designed into a column shape, and magnetic marbles are arranged along a radial direction of the lock core between the lock core and a hole sleeve. The key is designed into the column shape correspondingly and simultaneously. In addition, a high-magnetic sheet corresponding to the magnetic marbles is arranged on the key, and the polarity of the magnetic marbles is different from that of a near end of the high-magnetic sheet, that is to say, the magnetic column adopts the drawing-away type design. So the utility model increases the arrangement area of the magnetic marbles and the high-magnetic sheet. In addition, the drawing-away type column surface magnetic coded lock core and a key which have the advantages of simple structure, easy manufacture, low mutual-unlocking rate, high reliability, easy implementation, etc. can be used for various locksets.
Description
The utility model relates to a kind of magnetic padlock and key thereof, specifically a kind of formula cylinder magnetic coded lock core and key thereof of drawing away.
The magnetic padlock of existing design, it as the patent No. 93234492,94216730 magnetic padlock, its key all is a sheet, the end face at lock core is generally all opened in the hole of set dress magnetic marble on the lock core, or the cylinder of lock core, its position that can arrange magnetic marble on lock core is less, therefore, make the magnetic password can not be very complicated, the mutual opening rate height.The magnetic padlock that also has adopts to scold offers meter, and its complex structure is difficult to implement, and open unreliable.
The purpose of this utility model is that raising is a kind of can increase magnetic marble and strong magnetic piece arrangement areas, and lock core that mutual opening rate is low, reliability is high and key thereof.
The utility model is to realize its goal of the invention by the following technical solutions.A kind of formula cylinder magnetic coded lock core and key thereof of drawing away, comprise key, lock core, magnetic marble, strong magnetic piece, lock body, borehole jack, the keyhole of lock core is designed to cylindricality, between lock core and borehole jack, magnetic marble is arranged along the lock core radial arrangement, the key respective design becomes cylindricality, and be provided with on the key and the corresponding strong magnetic piece of magnetic marble, and the polarity of magnetic marble and strong magnetic piece near-end is different.
Simple for implementing, the utility model all is designed to cylinder with keyhole and key thereof.
The utility model can be provided with key core in key, strong magnetic piece is located at the external surface of key core.
When keyhole more greatly and in short-term, also key design can be become hollow cylinder, and in keyhole, be correspondingly provided with core bar.
Because adopt technique scheme, the utility model has ideally been realized its goal of the invention, its mutual opening rate is low, adopts to draw away the formula design, and the reliability height has simple in structurely, and handling ease, and characteristics such as enforcement easily can be widely used on the multiple lockset.
Accompanying drawing is the structural representation of the utility model embodiment 1.
The utility model is described in further detail for the contrast accompanying drawing below.
Embodiment 1:
By accompanying drawing as can be known, the utility model comprises key 1, lock core 5, magnetic marble 6, strong magnetic piece 3, lock body 7, borehole jack 4, keyhole in the lock core 5 is designed to cylindricality, can be designed to cylinder, cylindroid or 3-8 prism (present embodiment is a cylinder), between lock core 5 and borehole jack, magnetic marble 6 is arranged along the lock core radial arrangement, simultaneously with the corresponding key 1 of keyhole (present embodiment also is cylinder) on be provided with magnetic marble 6 corresponding strong magnetic pieces 3 that (present embodiment is to be provided with key core 2 in key 1, strong magnetic piece 3 is located at the external surface of key core 2), and magnetic marble 6 is different with the polarity of strong magnetic piece 3 near-ends; For key 1 and lock core 5 are accurately located, the b place is provided with a breach in the outer face of lock core 5, and corresponding C place at key 1 is provided with one and breach corresponding projections.When key 1 does not insert, because of attracting lock body 7 faces made of iron, magnetic marble 6 is stuck between the lock core 5 and borehole jack 4 that nonmagnetic substance makes, and make lock core 5 not do relative motion with borehole jack 4; But when key 1 inserts, strong magnetic piece 3 on the key 1 just and each magnetic marble 6 on the lock core 5 on the position, align, and polarity is different, all magnetic marbles 6 all are drawn in the pellet shot from a slingshot hole of lock core 5, like this, can make lock core 5 and borehole jack 4 do relative motion, promptly axially and rotatablely move, drive the cooperation of core bar 8 and other mechanisms, realize opening or closing the purpose of locking.
Embodiment 2:
When keyhole more greatly and in short-term, for increasing confidentiality, key design is become hollow cylinder, with core bar 8 corresponding extending in the keyhole, surplus with embodiment 1.
