Abstract
The utility model provides a lock head of an improved magnetic card lock, which is composed of a lock core component, a transmission component, an auxiliary component compliance magnetic sheet, and a reed. A pin-slot type clutch is arranged between the lock core component and the transmission component. The lock core component is composed of a lock core plate, a lock sheet, a left baffle sheet, a right baffle sheet, a short magnetic column, a long magnetic column and a lock core seat. A key card and a code changing card are arranged on both sides of the lock core plate. The code changing card is provided with a semicircular orientable keyway. Two circular arc grooves with different depth are arranged on a transmission disk. A code changing notch is arranged on the large circumference, and a handle and an end cover are screwed as integration. The utility model has the advantages of reasonable structure and high safety.
Description
The utility model relates to a kind of magnetic card lock tapered end, also is the outer handle of the spherical door lock of magnetic card.
Existing magnetic card lock tapered end is a lot, and conclusion is got up, and a kind of is that coding is many, and safety performance is good, but its structure is all unreasonable; Another kind is that structure is more reasonable, but can not become sign indicating number, and coding is few, and safety is relatively poor.More than two kinds all exist safety not high, prized problem such as effect is not ideal enough easily.
The purpose of this utility model is at the deficiencies in the prior art, provides a kind of safe, the change sign indicating number magnetic card lock tapered end of function admirable.
The utility model is achieved in that
The utility model is by the lock core assembly, and drive disk assembly and the attached part paramagnetic sheet that helps, reed are packed into jointly and constituted in the shell of an integral body, and wherein the lock core assembly is loaded on lock core base and is formed by cylinder plate, locking plate, left and right sides catch, length magnetic post and location, reposition element.In two sides of cylinder plate, to set up key card and become the sign indicating number card, the polarity that magnetizes in the key card is identical with magnetic column polarity in the cylinder plate and repel each other, and becomes the magnetic column polarity suction mutually on the contrary mutually in magnetize polarity and the cylinder plate in the sign indicating number card.Drive disk assembly is made of azimuth circle, two-way torsion spring, driver chuck, handle shell, end cap, is provided with two arc grooves at the driver chuck inner chamber, also is provided with a long rabbet and and becomes sign indicating number card designator on big circumference, can indicate the action when becoming sign indicating number.The change sign indicating number is arranged with the semi-circular orientation key and is pickled with grains or in wine, and can avoid positive and negative to misplug.Handle and end cap have an overall structure with after being threaded.
The utility model compared with prior art, handle and end cap are an overall structure, difficult quilt is prized, jam plate is provided with a lot of magnetic column lockholes, safe probability height, each parts design is rational in infrastructure, and is multiple functional.
Accompanying drawing 1 is the utility model structure diagram.
Accompanying drawing 2 is the utility model driver chuck structural representation.
Accompanying drawing 3 becomes sign indicating number card structure schematic diagram for the utility model.
Accompanying drawing 4 is the utility model handle shell mechanism sketch.
Below in conjunction with accompanying drawing the utility model being done one elaborates.
As shown in Figure 1, the utility model is reached by lock core assembly, drive disk assembly, paramagnetic sheet (6) Reed (7) is jointly packed into and is consisted of in the shell (10) of an integral body, and wherein the lock core assembly uses logical Normal plug-in type, it is by cylinder plate (3), locking plate (5), left and right sides catch (2) (4), length magnetic post (8) (9) and location, reposition element are loaded in the lock core base (1) by screw and form left and right sides catch (2) (4) be used for the length magnetic post (8) (9) of cylinder plate (3) is carried out blocking function, in cylinder plate (3) Two sides, set up key card (11) and become code card (12), in the key card (11) magnetize polarity with Magnetic column polarity in the lock core utmost point (3) is identical and repel each other, and becomes magnetize polarity and lock in the code card (12) Magnetic column polarity in the central layer (3) is inhaled mutually on the contrary mutually.
Drive disk assembly of the present utility model by azimuth circle (13), two-way torsion spring (15), driver chuck (16), Handle shell (10) and end cap (17) form, and wherein driver chuck (16) inner chamber is provided with two arc grooves (19) (20), as shown in Figure 2, can be for key card in use by predetermined direction revolution and fixed The position is provided with a long rabbet (21) at big circumference, becomes code card designator (22), can indicate to become code The time action, and show from the change code window of handle shell (10), at driver chuck (16) also Be provided with spring and collude (14), adapter sleeve (18).
As shown in Figure 3, change code card of the present utility model (12) is provided with semi-circular orientation keyway (23).
As shown in Figure 4, handle shell (10) has the structure of a globality with after end cap (17) is connected with screw thread (24) (25), has two change sign indicating number card plugs (26) different in size and key card socket (27) on handle shell (10).
Adopted cotter way formula clutch between lock core assembly of the present utility model and drive disk assembly, at ordinary times, clutch always is in the position of " closing ", so short magnetic post (9) is subjected to the effect of paramagnetic sheet (6), the magnetic post has fastened locking plate (5), lock also is in the close position, when using the key card of setting, and orders about cylinder plate (3) displacement, like this, just clutch push to from the position, will turn round when refusing to be added on outer handle, just immediately lock has been opened.
In the use, magnetic card can be made key card, control card and change sign indicating number card, and the key card control card is child and parent card, becomes the sign indicating number card and is encrypted card.
Embodiment:
Establish 22 magnetic column lockholes in cylinder plate, calculate according to theory, its system coding has 70.5 ten thousand, and assembly coding has 4,200,000, and random coded has 55.88 hundred million, and as seen this product mutual opening rate is low, the height of safe probability.
Claims (3)
