[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] Example:

[0026] like Figure 1-5As shown, this embodiment of the invention provides a card reader insertion structure, including a card reader body 1. The card reader body 1 has a slot 2 inside, which is mainly used for inserting SD cards. An insertion port 4 is provided on the right side wall of the card reader body 1, and the insertion port 4 corresponds to the slot 2. A sliding groove 5 is provided inside the card reader body 1, and the sliding groove 5 is located on the upper and lower sides of the slot 2. A sliding rod 6 is fixedly connected between the left and right inner walls of the sliding groove 5. A slider 7 is slidably connected to the circumferential surface of the sliding rod 6. A first compression spring 8 is sleeved on the circumferential surface of the sliding rod 6. The compression spring 8 is located to the right of the slider 7. The first compression spring 8 is always in a compressed state, and its elasticity controls the slider 7 to move the connecting plate 11 and the sealing plate 14 to one side of the card reader body 1, so that the sealing gasket 15 blocks the slot 4, preventing particulate matter and paper from entering the interior of the slot 2. This prevents the user from directly inserting the SD card into the slot 2, which could damage the card reader components or cause the card reader to malfunction. Simultaneously, when the SD card is being recognized, the first compression spring 8 also controls the sealing plate 14 to press against the SD card, ensuring... The SD card can contact the card reader components. The card reader body 1 has limit slots 9 at both the top and bottom, and these limit slots 9 are connected to the slide groove 5. A limit block 13 is slidably connected inside the limit slot 9. The limit slots 9 and the limit block 13 primarily limit the connection plate 11, preventing the connecting plate 11 from rotating when the sealing plate 14 blocks the slot 4 or when the sealing plate 14 presses against the SD card. When the slider 7 moves to the rightmost end of the slide groove 5, the limit block 13 moves out of the limit slot 9, facilitating the rotation of the connecting plate 11 and opening the sealing plate 14. To facilitate the insertion of the SD card into the slot 2, a connecting plate 11 is fixedly connected to the side of the limiting block 13 away from the slide groove 5, and the connecting plate 11 is located on the outside of the card reader body 1. A rotating hole 12 is provided inside the connecting plate 11. A rotating rod 10 is fixedly connected to the side of the slider 7 away from the slot 2, and the rotating rod 10 is located inside the limiting groove 9. The end of the rotating rod 10 away from the slider 7 extends into the interior of the rotating hole 12. A sealing plate 14 is fixedly connected to the right side wall of the connecting plate 11, and a sealing gasket 15 is fixedly connected to the side of the sealing plate 14 close to the card reader body 1.

[0027] A positioning hole 16 is provided on the side of the sealing gasket 15 near the card reader body 1. The positioning hole 16 facilitates the positioning of the SD card and allows the clamping block 19 to hold the SD card. When the SD card is inserted, one-quarter of the SD card is located on the outside. Reception slots 17 are provided at the top and bottom of the positioning hole 16 to accommodate the clamping block 19, preventing the clamping block 19 from interfering with the insertion of the SD card into the positioning hole 16. A pressing rod 18 is slidably connected inside the connecting plate 11. The end of the pressing rod 18 located inside the reception slot 17 is fixedly connected to the clamping block 19, and the end of the pressing rod 18 away from the clamping block 19 is fixedly connected to a pressing block 20. The pressing block 20 is located on the side of the connecting plate 11 away from the sealing gasket 15. The pressing block 20 is used for... The control lever 18 drives the clamping block 19 to move, so that the clamping block 19 clamps the SD card inside the positioning hole 16. When the sealing plate 14 is opened, the SD card is pulled out from the inside of the slot 2. When the SD card is completely pulled out, the pressing block 20 is released, and then the SD card can be taken out from the inside of the positioning hole 16. A blocking ring 21 is fixedly connected to the circumferential surface of the pressing lever 18, and the blocking ring 21 is located between the connecting plate 11 and the sealing gasket 15. A second compression spring 22 is sleeved on the circumferential surface of the pressing lever 18, and the second compression spring 22 is located between the pressing block 20 and the connecting plate 11. The second compression spring 22 is always in a compressed state, and the elastic force of the second compression spring 22 is used to move the clamping block 19 back into the storage slot 17 and release the SD card.

[0028] A USB connector 3 is provided on the left side wall of the card reader body 1, and a card reading component is provided on the left inner wall of the slot 2. The card reading component is electrically connected to the USB connector 3. The card reading component is mainly used to read the data inside the SD card. The rotating hole 12 is located on the left side of the connecting plate 11, and the pressing rod 18 is located on the right side of the connecting plate 11. The rotating rod 10 is rotatably connected to the inner wall of the rotating hole 12. The slider 7 is slidably connected to the slide groove 5. The connecting plate 11 is slidably connected to the card reader body 1. The positioning hole 16 is correspondingly set to the slot 4. The pressing rod 18 is a square rod to prevent the pressing rod 18 from driving the clamp 19 to rotate, ensuring that the clamp 19 can move smoothly from the inside of the positioning hole 16 into the storage slot 17. The clamp 19 is adapted to the storage slot 17, and the clamp 19 is made of rubber material.

[0029] Working principle: In use, first pull the sealing plate 14 to move the connecting plate 11 to the right. When the limiting block 13 moves out of the limiting groove 9, rotate the connecting plate 11 and move the sealing plate 14 to the rear of the card reader body 1. Then, insert the SD card into the slot 2 through the insertion port 4. Next, rotate the sealing plate 14 to the right side of the card reader body 1. At this time, the limiting block 13 is aligned with the limiting groove 9. Then, release the sealing plate 14. Under the action of the first compression spring 8, the sealing plate 14 squeezes the SD card. At the same time, the SD card is located inside the positioning hole 16. After the SD card is read, manually squeeze the pressing block 20 to clamp the card. Block 19 clamps the SD card inside the positioning hole 16 under the action of the second compression spring 22. At the same time, it pulls the connecting plate 11 to the right and pulls the SD card out of the slot 2. Then, the pressing block 20 is released, and the clamping block 19 releases the SD card. After that, the SD card can be taken out from the positioning hole 16. After the SD card is taken out, the connecting plate 11 is released, and the sealing plate 14 blocks the insertion port 4 under the action of the first compression spring 8 to prevent granular objects and paper from entering the inside of the slot 2. This prevents the user from directly inserting the SD card into the slot 2, which could damage the card reading components inside the card reader or cause it to become unreadable.
