Abstract
The utility model relates to a magnetic card for preventing demagnetization, which mainly solves the problem that the magnetic card has inconvenient carrying caused by that the existing shielding box protects the magnetic card from being demagnetized. The demagnetization prevention magnetic card comprises a magnetic strip and a card, wherein one side of the card is provided with the magnetic strip; a position corresponding to the magnetic strip in the card is inlaid with a shielding piece; a sliding groove is respectively arranged on the card at both sides of the magnetic strip; a shielding push cover is clamped and fixed on the sliding grooves through sliding keys at both sides of the shielding push cover. The shielding piece and the shielding push cover is made of soft magnetic materials with high magnetic permeability; the shielding push cover is matched with the shielding piece embedded into the card to form a shielding chamber composed of soft magnetic materials with high magnetic permeability for shielding external magnetic force. The utility model has the advantages of good shielding effect, convenient carrying and simple design by compared with the past shielding boxes.
Description
Technical field
The utility model relates to a kind of magnetic card, specifically is a kind of anti-demagnetization magnetic card.
Background technology
Magnetic card is easy to be magnetized and demagnetization by other magnetisable material.Because the cavity that the soft magnetic material that magnetic permeability is high constitutes has the effect of shielding magnetic force, so, be used at present prevent that magnetic card from being to utilize the high soft magnetic material of magnetic permeability to make shielding box by the major measure of demagnetization, magnetic card is placed in the shielding box is protected.This kind measure can effectively prevent magnetic card by demagnetization, and that but causes magnetic card carries shortcomings such as inconvenience, manufacturing cost height.
Summary of the invention
The utility model mainly solves existing shielding box protection magnetic card and is not caused magnetic card to carry inconvenient problem by demagnetization, and a kind of anti-demagnetization magnetic card that is convenient for carrying is provided.
The utility model is to adopt following technical scheme to realize: a kind of anti-demagnetization magnetic card, comprise that one side is provided with the card of magnetic stripe, position corresponding with magnetic stripe in the card is embedded with shield blade, have sliding tray respectively on the card of magnetic stripe both sides, the shielding pushing cover fixes on sliding tray by the slide key of its both sides.The shielding pushing cover cooperates connection by the slide key that is provided with sliding tray, cooperate with the shield blade that embeds card, forms a shielding cavity that is made of the high soft magnetic material of magnetic permeability, shields external magnetic force.During use, will shield pushing cover along sliding tray and pull out with card and separate, magnetic stripe breaks away from shielding.Use, the shielding pushing cover of taking off is pushed along sliding tray, it shields external magnetic force with the shielding cavity that the shield blade that embeds card is formed, and the protection magnetic stripe is not by demagnetization.
Shield blade have two lateral bucklings and with the flanging of card upper surface flush.Flanging and shield blade, shielding pushing cover are formed shielding cavity magnetic stripe are wrapped in wherein, the magnetic force that flanging makes up shielding and penetrates from card side, and the shield effectiveness of shielding cavity is better.
Sliding tray is in the inboard of flanging.Flanging and shield blade, shielding pushing cover are formed shielding cavity, the magnetic force that flanging makes up shielding and penetrates from the shielding cavity joint, and the shield effectiveness of shielding cavity is better.
The utility model shield effectiveness is good, compare with shielding box in the past have be convenient for carrying, simplicity of design, practical advantage.

Embodiment
A kind of anti-demagnetization magnetic card comprises that one side is provided with the card 4 of magnetic stripe 6, and position corresponding with magnetic stripe 6 in the card 4 is embedded with shield blade 2, has sliding tray 5 respectively on the card 4 of magnetic stripe 6 both sides, and shielding pushing cover 1 fixes on sliding tray 5 by the slide key 3 of its both sides.
Shield blade 2 have two lateral bucklings and with the flanging 7 of card 4 upper surface flush.Flanging 7 and shield blade 2, shielding pushing cover 1 are formed shielding cavity magnetic stripe 6 are wrapped in wherein, the magnetic force that flanging 7 makes up shielding and penetrates from card 4 sides, and the shield effectiveness of shielding cavity is better.
Sliding tray 5 is in flanging 7 inboards.Flanging 7 and shield blade 2, shielding pushing cover 1 are formed shielding cavity, the magnetic force that flanging 7 makes up shielding and penetrates from the shielding cavity joint, and shield effectiveness is good.
The soft magnetic material that magnetic permeability is high is made shield blade 2 and shielding pushing cover 1, and shield blade 2 embeds the corresponding position of cards 4 and magnetic stripe 6, and the thickness of shield blade 2 is between 0.2mm--1mm.
Shielding pushing cover 1 slide key 3 by setting cooperates connection with sliding tray 5, cooperates with the shield blade 2 that embeds card 4, forms a shielding cavity that is made of the high soft magnetic material of magnetic permeability, shields external magnetic force.During use, will shield pushing cover 1 along sliding tray 5 and pull out with card 4 and separate, magnetic stripe 6 breaks away from shielding.Use, the shielding pushing cover 1 of taking off is pushed along sliding tray 5, it shields external magnetic force with the shielding cavity that the shield blade 2 that embeds card 4 is formed, and protection magnetic stripe 6 is not by demagnetization.
