Abstract
The utility model discloses a magnetic card lock core and a magnetic card, particularly an anti-magnetic interference safety magnetic card lock core and the special magnetic card thereof, which solves the defects of the original magnetic lock that the code capacity is less, the performance is single, the magnetic interference resisting ability is poor, and the safety rate is low. The anti-magnetic interference safety magnetic card lock core of the utility model is composed of a lock shell, a lock sleeve, a slide lock core, an anti-interference magnet, a slide magnet, a slide positioning pin and a spring. The appearance of the special magnetic card is a rectangle plate. The inner of the special magnetic card is forged with small holes according to the coding sequence, and code magnets are arranged in the small holes. The utility model has the advantages of large code capacity, strong interference resisting ability and higher security, and the special magnetic card is not easy to copy.
Description
The utility model discloses a kind of magnetic card lock core and magnetic card, particularly a kind of diamagnetic interference magnetic insurance magnetic card lock core and special-purpose magnetic card thereof.
At present, safety cabinet, security door and the employed lockset of various vehicle adopt mechanical cylinder lock mostly, this kind lockset mutual opening rate height, and key easily is replicated.Developed multiple magnetic lock in recent years both at home and abroad, but these lockset password capacity are few, performance is single, and safety coefficient is low; A little less than the diamagnetic interference performance, in use easily break down, can not satisfy actual needs.
The purpose of this utility model is to provide strong, the safe and reliable diamagnetic interference magnetic of big, the diamagnetic interference performance of a kind of password capacity to insure magnetic card lock core and special-purpose magnetic card thereof.
The purpose of this utility model is achieved in that
A. diamagnetic interference magnetic insurance magnetic card lock core: constitute by lock housing, lock tube, slip lock core, anti-interference magnet, sliding magnet, slide jaw and spring; Wherein slide and make poroid slideway according to coded sequence in the lock tube of both sides up and down of lock core, anti-interference magnet and sliding magnet are housed in the slideway successively, the anti-interference magnet and the sliding magnet antipode utmost point are to aligned identical; Offer the slip dimple according to coded sequence on the slip lock core; The afterbody of slip lock core is equipped with spring; Offer a pin-and-hole in the lock tube, slide jaw is housed in the pin-and-hole; The position corresponding with slide jaw offers a slip locating slot on the slip lock core;
B. special-purpose magnetic card: outward appearance is a rectangle plate, and aperture has been made according to coded sequence in inside, and password magnet is housed in the hole, and the corresponding utmost point utmost point with sliding magnet of password magnet is to aligned identical.
Adopted the utility model of said structure, the anti-interference magnet in the lock core in use can be eliminated the magnetic interference of inside and outside; Because the password magnet on the magnetic card can make that this lock core cipher capacity is big according to coded sequence with multiple different formal representation, magnetic card is difficult for being replicated, and has higher safety.
Below in conjunction with accompanying drawing the utility model is described further.
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is the profile of A-A in the utility model.
Referring to accompanying drawing, diamagnetic interference magnetic insurance magnetic card lock core is made of lock housing 1, lock tube 2, slip lock core 3, anti-interference magnet 4, sliding magnet 5, slide jaw 9 and spring 6 in the utility model; Wherein slide and make poroid slideway 10 according to coded sequence in the lock tube 2 of both sides up and down of lock core 3, anti-interference magnet 4 and sliding magnet 5 are housed in the slideway 10 successively, magnet 4 and 5 be shaped as cylindrical; The anti-interference magnet 4 and the sliding magnet 5 antipode utmost points are to aligned identical; Offer slip dimple 11 according to coded sequence on the slip lock core 3, slip dimple 11 be shaped as circle; The afterbody of slip lock core 3 is equipped with spring 6; Offer a pin-and-hole 12 in the lock tube 2, slide jaw 9 is housed in the pin-and-hole 12; Position corresponding with slide jaw 9 on the slip lock core 3 offers a slip locating slot 15;
The outward appearance of magnetic card 7 is a rectangle plate, and matrix surface adopts metal thin shell or other material packing to form, and aperture 14 has been made according to coded sequence in inside, and password magnet 8 is housed in the hole 14; The position, hole of the aperture 14 on the magnetic card 7, the slip dimple 11 on the slip lock core 3 and the slideway 10 on the lock tube 2 is adopted same-code to make in proper order and is formed; Password magnet 8 and the sliding magnet 5 corresponding utmost point utmost points are to aligned identical.
During unlatching, in the slip lock core 3 of diamagnetic interference magnetic insurance magnetic card lock core, insert supporting with it magnetic card 7, because the password magnet 8 and the slideway 10 interior sliding magnet 5 antipode utmost points are to aligned identical in the magnetic card 7, the active force of 8 pairs of sliding magnets 5 of password magnet is greater than the active force of 4 pairs of sliding magnets 5 of anti-interference magnet, thereby make sliding magnet 5 be pushed out slip dimple 11 and all enter slideway 10, the lock function of lock core promptly is disengaged; Slip lock core 3 moves forward under the effect of external force, and spring 6 is compressed; When slip lock core 3 moves to certain distance, the slided length restriction of locating slot 15 of slide jaw 9 can not move forward again, the fork that the lock core 3 of sliding simultaneously drives has been finished the stirring of leverage in the outside lock box, thereby has realized open function;
When extracting magnetic card 7 out, the external force that promotes slip lock core 3 disappears, and slip lock core 3 produces under the active force of spring 6 and resets; When making the position at the beginning of resetting to, sliding magnet 5 is pushed into slip dimple 11 under anti-interference magnet 4 effects, and lock core is promptly locked.
