[0002] A smart card is a general term for a plastic card with a microchip embedded in it, usually the size of a credit card. Long-term use can easily cause wear and tear on the outer surface of the smart card, causing damage to the smart card and making it unusable. Reissuing a new card will waste a lot of time and cause certain economic losses, so a protective structure is adopted. The current anti-scratch structure of the smart card includes a protective cover made of soft transparent plastic with an opening at one end. When in use, the smart card is placed inside the protective cover along the opening. Since the opening is open, the smart card may fall during bumps, increasing the trouble for users to find and replace the card.

[0013] The utility model provides an anti-scratch smart card structure, which, when implemented:

[0014] 1. Insert the smart card into the protective cover along the opening of the limiter to prevent the smart card from being scratched. When inserting, the smart card is squeezed into the groove through the inclined surface of the card block, and the card block presses the limit spring.

[0023] In the specific implementation process, Figure 1 - Figure 4 As shown, an anti-scratch smart card structure includes a limiter 1 and a protective cover 2. A through opening 3 is provided on one side of the limiter 1, and the protective cover 2 is fixedly connected to the other side of the limiter 1. A limiting mechanism is fixedly arranged inside the limiter 1, and a supporting mechanism is fixedly arranged inside the protective cover 2; the limiting mechanism includes a limiting spring 5, a card block 6 and an auxiliary spring 9. Grooves 4 are provided on both sides of the upper end of the limiter 1, and card blocks 6 are slidably connected inside the two grooves 4. One end of the card block 6 passes through the upper end of the limiter 1, and a limiting spring 5 is fixed between the two card blocks 6 and the inner top surface of the groove 4. Two slide grooves 8 are provided on one side of the limiter 1, and transmission blocks 7 are slidably arranged inside the two slide grooves 8. One side of the two transmission blocks 7 is fixed It is connected to a transmission plate 10, and a card block 6 is fixedly connected to the other side of the two transmission blocks 7. An auxiliary spring 9 is fixedly arranged between the upper end surfaces of the two transmission blocks 7 and the inner top surface of the slide groove 8. The height and width of the opening 3 are larger than the thickness and width dimensions of most smart cards. The height dimension of the opening 3 is larger than the height dimension of the two slide grooves 8. One end of the protective cover 2 completely wraps the through opening 3 opened on one side of the limiter 1. The outer wall edges of the protective cover 2 are provided with arc surfaces. A slope is provided on one side of the card block 6, and the slope faces the direction of the protective cover 2. The supporting mechanism includes an airbag 11.

[0024] The working principle provided by the utility model is as follows: the smart card is inserted into the protective sleeve 2 along the opening 3 of the limiter 1 to prevent the smart card from being scratched. When inserting, the smart card squeezes the card block 6 into the groove 4 through the inclined surface of the card block 6, and the card block 6 squeezes the limit spring 5. When the smart card completely enters the protective sleeve 2, the limit spring 5 resets and the card block 6 pops out to block the opening 3. When taking out the smart card, the transmission plate 10 is bent upward, and the transmission plate 10 drives the card block 6 to move into the groove 4 through the transmission block 7 to open the opening 3, and then the smart card can be poured out.
