Description

A kind of magnetic lock

Technical field

The utility model relates to a kind of lockset, especially a kind of magnetic lock.

Background technology

A lot of lock products are arranged on market at present, the lock product also is absolutely necessary in our daily life, at door, car, the application of locking in the various field such as safety cabinet all is very widely, the lock significant feature is exactly antitheft and safety effect, present lock on the market, because the pellet shot from a slingshot in the lock core is arranged in the pellet shot from a slingshot hole, add resetting structure, in like this in key injects keyhole, key flicks pellet shot from a slingshot, carries out release, because the pellet shot from a slingshot hole is exposed in keyhole, so can the pellet shot from a slingshot of locking be flicked by some apparatus of unblanking, therefore present lock is easy to be opened by the people, antitheft and security performance is not very high.

Summary of the invention

The purpose of this utility model is, a kind of simple in structure, safe and reliable magnetic lock is provided.

The utility model is achieved by the following scheme: a kind of magnetic lock, comprise key, lock body, lock core, described lock core is arranged in the lock body, it is characterized in that lock core also is provided with no magnetic padlock core retainer plate outward, the periphery of lock core cover also is provided with metal shell, the surface of lock core is provided with at least one pit, put with the corresponding position of pit at no Magnetic lock cylinder and to be provided with the through hole adaptive with pit, put at no Magnetic lock cylinder and to be provided with the opposite magnet of pair of magnetic in the through hole, be provided with and the suitable magnet of through hole internal magnet in the end of key, the magnetic of key end magnet is greater than the magnetic of through hole internal magnet.

This is arranged on lock core and has partly adopted the structure of atresia lock core (not having the pellet shot from a slingshot hole) with the socket of no magnetic padlock core retainer plate and metal shell, and the opposite magnet of pair of magnetic is set in the through hole of no magnetic padlock core retainer plate, and (magnetic of indication is meant that on the contrary the polarity of two magnet contact surfaces is identical herein, promptly repel mutually), be provided with in the end of key with the through hole internal magnet as adaptive magnet, and the magnetic of key end magnet must be greater than the magnetic of through hole internal magnet, magnet in the through hole could be pushed open like this, because through hole and keyhole are not communicated with, therefore all nonmagnetic unlocking tools have no idea to unblank, owing to can be provided with a plurality of at the lock core pit, and the polarity that the inside is provided with magnet can be crisscross arranged, the magnetic power of every pair of magnet can be done different adjustment, even therefore also very difficult all magnet is flicked of magnetic unlocking tool carried out release, therefore increased safety greatly, because the pair of magnet in this is provided with the inside through hole, the magnet that wherein is arranged in the pit is as pellet shot from a slingshot, another magnet can be adsorbed on the inner surface of metal shell, as a device that resets and lock, simplified the internal construction of conventional lock greatly, reduced and produced required cost.

Of the present utility modelly further be set to: described lock core is roughly cylindrical, one end of lock core is provided with flange, the corresponding end of lock tube and flange is provided with a cavity that is rotatably assorted with flange, on the flange of lock core, be provided with breach, be provided with a projection adaptive in the end of key with breach.

This end that is arranged on lock core is provided with flange, the corresponding end of lock tube and flange is provided with a cavity that is rotatably assorted with flange, on the flange of lock core, be provided with breach, be provided with a projection adaptive with breach in the end of key, like this labyrinth of having simplified original lockhole is set, realize the function of rotational lock core with a simple interface arrangment, simplified technological process simultaneously, reduced cost of processing.

Of the present utility modelly further be set to: an end that is provided with keyhole on lock body also is provided with dust cover, an end of described dust cover opening and lock body clamping, and an end of sealing is provided with one and renovates, and renovates with dust cover hingedly, is provided with torsion spring in its articulated section.

This outside that is arranged on lock body also is provided with a dust cover; also being provided with one on the dust cover renovates; keyhole and extraneous environment are kept apart in being provided with like this; because the utility model is unblanked by this journey; therefore, placement dust or impurity enter keyhole and are necessary, in case dust or impurity enter the words of keyhole; understand wearing and tearing key and lockhole, reduced the life-span of whole magnetic lock.

Said structure has adopted the structure of atresia lock core (not having the pellet shot from a slingshot hole) with the socket of no magnetic padlock core retainer plate and metal shell, rotational structure has also been done and has been simplified convenient processing, and the end that is provided with keyhole at lock body is provided with dust cap, simplify greatly on the overall structure, and increased Product Safety, reduce production costs, prolonged the Chen Pin life-span, expanded the market applicability of product greatly.

The specific embodiment

With reference to figure 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 as can be known, a kind of magnetic lock of the utility model, comprise key 1, lock body 2, lock core 3, described lock core 3 is arranged in the lock body 2, lock core 3 outer sheathed successively from the inside to surface no magnetic padlock core retainer plates 4, metal shell 5, the surface of lock core 3 is provided with five pits 31, on no magnetic padlock core retainer plate 4, be provided with the through hole 41 adaptive with pit 31 with pit 31 corresponding positions, through hole 41 is corresponding one by one with pit 31, on no magnetic padlock core retainer plate 4, be provided with the opposite magnet of pair of magnetic 6 in the through hole 41, be provided with in the end of key 1 and the suitable magnet 6 of through hole 41 internal magnets 6, the magnetic of key 1 end magnet 6 is greater than the magnetic of through hole 41 internal magnets 6, wherein in the through hole 41 near the magnet 6 of pit 31 as pellet shot from a slingshot, another magnet 6 is adsorbed on the metal shell 5, two magnet, 6 magnetic are opposite, constitute a resetting structure, magnet 6 positions that are arranged on key 1 end are corresponding with pit 31 positions, magnetic is opposite with magnet 6 magnetic of close pit 31, and be eager to excel than the magnetic that is adsorbed on magnet 6 on the metal shell 5, when key 1 injected keyhole 32, the magnet pellet shot from a slingshot just can flick like this.Described lock core 3 is roughly cylindrical; one end of lock core 3 is provided with flange 33; lock tube 4 is provided with a cavity 42 that is rotatably assorted with flange 33 with flange 33 corresponding ends; on the flange 33 of lock core 3, be provided with breach; be provided with a projection 11 adaptive with breach in the end of key 1; after finishing, assembling also is provided with dust cover 7 at an end that on lock body 2, is provided with keyhole; one end of described dust cover 7 openings and lock body 2 clampings; one end of sealing is provided with one and renovates 71; renovate 71 with dust cover 7 hinged; be provided with torsion spring in its articulated section; prevent that dust or impurity from entering keyhole and being necessary; in case dust or impurity enter keyhole, can wear and tear key and lockhole have reduced life-span of whole magnetic lock.

Magnet setting in the utility model through hole can be staggered, be that magnetic is staggered, each magnet towards pit is the N utmost point or the S utmost point, the number of pit and position also are free to set, improve the security performance of lock, as long as magnet is arranged to different polarity, the position and the number of pit is done different arrangement settings get final product.

The utility model reaches very high safety requirements with simple structure, has good practicability.
