Abstract
The utility model relates to a magnetic card clamp, in particular to a magnetic card safety clamp. It is composed of a plurality of flexible plastic interlayers, and the utility model is characterized in that a diamagnetic body composite layer is arranged between two adjacent interlayers. The utility model has the advantages that it has simple structure and it is easy in use, besides, it can prevent the magnetic of the magnetic card from being damaged.
Description
Technical field
The utility model relates to a kind of magnetic card folder, especially a kind of magnetic card safety clamp.
Background technology
Along with computer technology rapid development and widespread use, people are doing shopping, are withdrawing the money, checking out, can not be with cash when having a meal, as long as be with several AT magnetic cards just can pay the bill.Yet unfortunately so very how-do-you-do occurs through regular meeting, after you inserted magnetic card, " sir, your magnetic card damaged, asks cash payment to spread out of voice suggestion from computer.”。This phenomenon occurring mainly is because the magnetic of magnetic card is damaged, and therefore invents a kind of impaired magnetic card safety clamp of magnetic that can prevent and is highly profitable.
Summary of the invention
Technical problem to be solved in the utility model is the defective that exists at existing product, provides a kind of and can prevent the impaired magnetic card safety clamp of magnetic, to remedy the deficiency of existing product.
The technical solution of the utility model is achieved in that it comprises multilayer flexible plastic cover interlayer, is characterized in that: be provided with one deck diamagnet composite bed between the adjacent flexible plastic cover interlayer; One end of magnetic card is provided with knot that can be undone by a pull; The diamagnet composite bed is tinfoil layer or copper sheet layer.
The utlity model has advantage simple in structure, easy to use, can prevent that the magnetic of magnetic card is damaged.
Description of drawings
Fig. 1 is a structural representation of the present utility model
Concrete real mode
Below in conjunction with accompanying drawing the utility model is further described:
As shown in Figure 1, the utility model comprises multilayer flexible plastic cover interlayer 1, is provided with one deck diamagnet composite bed 2 between the adjacent flexible plastic cover interlayer; One end of magnetic card is provided with knot that can be undone by a pull 3; Diamagnet composite bed 2 is tinfoil layer or copper sheet layer.According to the attribute of diamagnet and the principle of magnetic shielding; the field weakening that this diamagnet separation layer can effectively produce the magnetic card that is stacked together adjacent; also the radiation interference that produces than high-intensity magnetic field in the external world can be masked simultaneously; separation layer has been eliminated between adjacent magnetic card and the magnetic card completely, the mutual interference mutually of magnetic card and extraneous high-intensity magnetic field, thereby reaches safely, deposits and protect the effect of AT magnetic card.
