Description

Technical Field

[0001] This invention relates to the field of card reader technology, specifically to a confidential scientific research information consulting service card device. Background Technology

[0002] An RFID card is a card that communicates with a reader (also known as a "radio board") via radio waves to identify the holder or item. Therefore, RFID cards have good encryption. In the process of consulting on scientific research information, readers are often used to identify the RFID card held by the person seeking information, thereby determining the identity of the person seeking information and preventing the leakage and theft of scientific research information.

[0003] Existing technologies, such as patent document CN211479099U, disclose an efficient card reading device for patent development consulting services. This device includes a base, a first support rod at the top of the base, a second support rod on one side of the first support rod, rotating rods on both sides of the second support rod, a third support rod movably connected to the rotating rods, a second base plate at one end of the third support rod, a touchscreen on the second base plate, a storage box at the bottom of the base, a printer inside the storage box, and a printer outlet at the bottom of the printer. This invention, through a wireless board and control panel, allows customers to view relevant patent development documents via a touchpad and then print the required documents using the printer. The overall integrated design facilitates the movement of the device.

[0004] The aforementioned and existing related technologies often have the following drawbacks: because the radio board is exposed during operation, it is easy for the radio board to receive radio waves emitted by RFID cards carried by people in the vicinity and to identify the RFID cards, which can easily lead to the information of people in the vicinity being read, posing a certain risk of information leakage.

[0005] To address this, we propose a classified scientific research information consulting service card device. Summary of the Invention

[0006] The purpose of this invention is to provide a confidential scientific research information consulting service card device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: a classified scientific research information consulting service card device, comprising a shell, a display screen fixedly connected inside the shell, a card reader fixedly connected inside the shell, and heat dissipation holes on the surface of the shell; further comprising: a shielding structure disposed on the surface of the shell to prevent misreading by the card reader, the shielding structure comprising a shielding shell fixedly installed on the surface of the shell and a pressure rod for pressing the RFID card tightly against the card reader; a storage structure disposed on the inner wall of the shielding shell for storing forgotten RFID cards, the storage structure comprising a rotating rod rotatably connected to the inner wall of the shielding shell, a semi-circular rod for facilitating the dropping of the RFID card, and a pedal for adjusting the position of the semi-circular rod; and a reset structure disposed on the side wall of the shell for automatically resetting the pedal, the reset structure comprising a fixing rod fixedly installed on the side wall of the shell, a reset plate for supporting the pedal, and a second spring for sliding the reset plate upward.

[0008] The aforementioned components achieve the following effects: By setting up a shielding structure, the card reader can be blocked during operation, preventing it from receiving radio waves emitted by RFID cards carried by nearby personnel. This prevents the information of those nearby from being read, ensuring the confidentiality of scientific research information consultation services. By setting up a storage structure, when the user forgets to remove the RFID card, it will slide into the storage box, which will collect and store the RFID card, preventing loss and improving the security and confidentiality of the device. By setting up a reset structure, the pedal will automatically rotate and reset after the user leaves, facilitating subsequent use for information consultation and improving the practicality of the device.

[0009] Preferably, a fixing plate is fixedly connected to the inner wall of the shielding shell, the vertical interface of the fixing plate is U-shaped, a sliding plate is slidably connected to the inner wall of the fixing plate, a round tube is fixedly connected to the surface of the sliding plate, the round tube is rotatably connected to the pressure rod, a strip plate slides through the shielding shell, a triangular block is fixedly connected to the surface of the strip plate, the inclined surface of the triangular block is slidably connected to the sliding plate, rectangular plates are fixedly connected to both ends of the strip plate, both ends of the pressure rod are conical structures, a positioning plate is fixedly connected to the inside of the shielding shell, and the shielding shell is made of aluminum alloy.

[0010] The above components achieve the following effect: When the user inserts the RFID card into the shielding shell, the RFID card will first contact the conical surface of the pressure rod. The conical surface of the pressure rod can guide the sliding path of the RFID card, making it convenient for the user to insert the RFID card. Under the influence of the gravity of the strip plate and the triangular block, the triangular block will press the slide plate downwards. The slide plate will slide towards the card reader. The round tube will drive the pressure rod to slide with the help of the slide plate. The pressure rod will push the RFID card to stick to the surface of the card reader, making it convenient for the card reader to read the RFID card.

[0011] Preferably, a push frame is slidably connected inside the shielding shell, one end of the push frame is provided with a triangular protrusion, a first spring is fixedly connected to the outer wall of the shielding shell, and the other end of the first spring is fixedly connected to the push frame.

[0012] The effect achieved by the above components is as follows: when the push frame is pulled away from the shielding shell, the sliding of the push frame will stretch the first spring, keeping the first spring in a stretched state. When the push frame slides to a certain position, it will contact the inner wall of the shielding shell, thereby preventing the push frame from being pulled out of the shielding shell. Then, the push frame is released, and the push frame will slide quickly towards the RFID card with the help of the elastic force of the first spring. The push frame will hit the RFID card, causing the RFID card to slide out of the shielding shell.

[0013] Preferably, a friction pad is fixedly connected to the outer shell relative to the position of the shielding shell.

[0014] The effect achieved by the above components is that after the RFID card comes into contact with the friction pad, the friction pad will cushion the RFID card with its own friction force to prevent the RFID card from falling off.

[0015] Preferably, the semi-circular rod is fixedly connected to the rotating rod, one end of the rotating rod is fixedly connected to a turntable, the pedal is rotatably connected to the outer shell, a transmission belt is fixedly connected to the surface of the pedal, the other end of the transmission belt is fixedly connected to the turntable, a storage frame is detachably installed on the surface of the outer shell, the storage frame is located below the semi-circular rod, a protective cover is fixedly connected to the surface of the outer shell, the transmission belt is located inside the protective cover, and an inclined plate is fixedly connected to the inner wall of the storage frame. The semi-circular rod, the storage frame, and the inclined plate are all made of aluminum alloy.

[0016] The above components achieve the following effects: after the pedal rotates to a certain angle, the transmission belt will be tightened. As the pedal continues to rotate, the transmission belt will drive the turntable to rotate. At this time, the protective cover can prevent the transmission belt from being touched and affecting its normal operation. The rotation of the turntable will drive the rotating rod to rotate, and the rotation of the rotating rod will drive the semi-circular rod to rotate, thereby adjusting the position of the semi-circular rod. The semi-circular rod will support the RFID card.

[0017] Preferably, a counterweight is rotatably connected to the surface of the turntable, and a baffle is fixedly connected to the outer wall of the shielding shell.

[0018] The effect achieved by the above components is as follows: as the counterweight rotates with the turntable, since the counterweight can rotate along the surface of the turntable, the counterweight will not press against the surface of the outer shell and hinder the normal rotation of the turntable. When the counterweight contacts the baffle, the turntable will stop rotating, and at this time the plane of the semi-circular rod will be horizontal and facing upward.

[0019] Preferably, a hollow plate is rotatably connected to the surface of the outer shell, a connecting plate is slidably connected to the inner wall of the hollow plate, the connecting plate is rotatably connected to the pedal, and a flexible hose is connected to the surface of the hollow plate and the flexible hose is connected to the outer shell.

[0020] The effect achieved by the above components is as follows: the rotation of the pedal will drive the connecting plate to rotate, and the connecting plate will insert into the hollow plate to compress the air inside the hollow plate. At this time, the air inside the hollow plate will flow into the outer shell through the hose, and then the air will be discharged through the heat dissipation holes. Therefore, when the pedal is stepped on, it will accelerate the air flow speed inside the outer shell, thereby dissipating heat from the electronic components inside the outer shell.

[0021] Preferably, the reset plate and the second spring are both sleeved on the arc surface of the fixed rod. The reset plate is slidably connected to the outer shell. The two ends of the second spring are fixedly connected to the outer shell and the reset plate, respectively. A block is fixedly connected to the side wall of the outer shell. A screw is threaded into the block. A rectangular rod is rotatably connected to one end of the screw. The rectangular rod is slidably connected to the outer shell. An elastic strip is fixedly connected to the surface of the rectangular rod. The elastic strip is made of rubber.

[0022] The aforementioned components achieve the following effect: When the user leaves the pedal, the second spring begins to contract, and the reset plate drives the pedal to rotate upward, thus automatically resetting the pedal. When it is necessary to control the rotation speed of the semi-circular rod by adjusting the pedal's reset speed, the screw is rotated. The rotation of the screw drives the rectangular rod to move, and the movement of the rectangular rod compresses the elastic strip. Since the elastic strip is pressed against the surface of the reset plate, it deforms under pressure. When the reset plate slides upward, the elastic strip uses its own friction to slow down the sliding speed of the reset plate. The greater the friction between the elastic strip and the reset plate, the slower the sliding speed of the reset plate, thus preventing the RFID card from falling into the storage box as soon as the user leaves the pedal.

[0023] Preferably, the elastic strip has an arc-shaped cavity, and a rigid plate is embedded in the elastic strip.

[0024] The effect achieved by the above components is that the rigid plate can make the pressure between the elastic strip and the reset plate uniform, thereby making the friction between the elastic strip and the reset plate uniform.

[0025] Preferably, a sealing plate is fixedly connected to the upper surface of the reset plate, and the sealing plate is slidably connected to the outer shell.

[0026] The effect achieved by the above components is that the sliding of the reset plate will cause the sealing plate to slide, and the sealing plate can block the second spring to prevent foreign objects from falling into the second spring and jamming it.

[0027] Compared with the prior art, the beneficial effects of the present invention are: 1. By setting up a shielding structure, this invention can block the card reader during its operation, preventing the card reader from receiving radio waves emitted by RFID cards carried by people in the vicinity, thereby preventing the information of people in the vicinity from being read and ensuring the confidentiality effect when providing scientific research information consulting services.

[0028] 2. By setting up a storage structure, the present invention allows the RFID card to slide into the storage box when the user forgets to take it out. The storage box will collect and store the RFID card, preventing the RFID card from being lost, thereby improving the security and confidentiality of the device.

[0029] 3. By setting a reset structure, the present invention can automatically rotate and reset the pedal after the user leaves the pedal, making it convenient for others to use the device for information consultation in the future, thereby improving the practicality of using the device.

Detailed Implementation

[0032] 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.

[0033] Please see Figure 1-11 This invention provides a technical solution: a classified scientific research information consulting service card device, including a shell 1, a display screen 2 fixedly connected inside the shell 1, a card reader 3 fixedly connected inside the shell 1, and heat dissipation holes 4 on the surface of the shell 1. It also includes: a shielding structure 5 disposed on the surface of the shell 1 to prevent misreading by the card reader 3, the shielding structure 5 including a shielding shell 501 fixedly installed on the surface of the shell 1, and a pressure rod 505 for pressing the RFID card tightly against the card reader 3; and a device for... A storage structure 6 for storing forgotten RFID cards includes a rotating rod 601 rotatably connected to the inner wall of the shielding shell 501, a semi-circular rod 602 for facilitating the dropping of RFID cards, and a pedal 605 for adjusting the position of the semi-circular rod 602. A reset structure 7 is provided on the side wall of the outer shell 1 for automatically resetting the pedal 605. The reset structure 7 includes a fixing rod 71 fixedly installed on the side wall of the outer shell 1, a reset plate 72 for supporting the pedal 605, and a second spring 73 for sliding the reset plate 72 upward.

[0034] like Figures 3-7As shown, a fixing plate 502 is fixedly connected to the inner wall of the shielding shell 501. The vertical interface of the fixing plate 502 is U-shaped. A sliding plate 503 is slidably connected to the inner wall of the fixing plate 502. A round tube 504 is fixedly connected to the surface of the sliding plate 503. The round tube 504 is rotatably connected to the pressure rod 505. A strip plate 506 slides through the shielding shell 501. A triangular block 507 is fixedly connected to the surface of the strip plate 506. The inclined surface of the triangular block 507 is slidably connected to the sliding plate 503. Rectangular plates 508 are fixedly connected to both ends of the strip plate 506. Both ends of the pressure rod 505 are conical structures. A positioning plate 511 is fixedly connected to the inside of the shielding shell 501. Made of aluminum alloy, when the user inserts the RFID card into the shielding shell 501, the RFID card will first contact the conical surface of the pressure rod 505. The conical surface of the pressure rod 505 can guide the sliding path of the RFID card, making it easier for the user to insert the RFID card. Under the influence of the gravity of the strip plate 506 and the triangular block 507, the triangular block 507 will press the slide plate 503 downward. The slide plate 503 will slide towards the card reader 3. The round tube 504 will drive the pressure rod 505 to slide with the help of the slide plate 503. The pressure rod 505 will push the RFID card to stick to the surface of the card reader 3, making it easier for the card reader 3 to read the RFID card. A push frame 509 is slidably connected inside the shielding shell 501. One end of the push frame 509 has a triangular protrusion. A first spring 510 is fixedly connected to the outer wall of the shielding shell 501. The other end of the first spring 510 is fixedly connected to the push frame 509. Pulling the push frame 509 away from the shielding shell 501 causes the push frame 509 to slide, stretching the first spring 510 and keeping it in a stretched state. When the push frame 509 slides to a certain position, it will contact the inner wall of the shielding shell 501, thus preventing the push frame 509 from being pulled out of the shielding shell 501. Then, releasing the push frame 509 causes it to slide quickly towards the RFID card with the help of the elastic force of the first spring 510. The push frame 509 will impact the RFID card, causing it to slide out of the shielding shell 501. A friction pad 512 is fixedly connected to the outer shell 1 relative to the shielding shell 501. After the RFID card contacts the friction pad 512, the friction pad 512 will cushion the RFID card with its own friction, preventing the RFID card from falling out.

[0035] like Figures 3-4 and Figure 8 as well as Figure 9As shown, the semi-circular rod 602 is fixedly connected to the rotating rod 601. One end of the rotating rod 601 is fixedly connected to the turntable 604. The pedal 605 is rotatably connected to the outer shell 1. A transmission belt 606 is fixedly connected to the surface of the pedal 605. The other end of the transmission belt 606 is fixedly connected to the turntable 604. A storage frame 603 is detachably installed on the surface of the outer shell 1. The storage frame 603 is located below the semi-circular rod 602. A protective cover 609 is fixedly connected to the surface of the outer shell 1. The transmission belt 606 is located inside the protective cover 609. An inclined plate 614 is fixedly connected to the inner wall of the storage frame 603. 602, storage frame 603, and inclined plate 614 are all made of aluminum alloy. After the pedal 605 rotates to a certain angle, it will tighten the transmission belt 606. As the pedal 605 continues to rotate, the transmission belt 606 will drive the turntable 604 to rotate. At this time, the protective cover 609 can prevent the transmission belt 606 from being touched and affecting the normal operation of the transmission belt 606. The rotation of the turntable 604 will drive the rotating rod 601 to rotate. The rotation of the rotating rod 601 will drive the semi-circular rod 602 to rotate, thereby adjusting the position of the semi-circular rod 602. The semi-circular rod 602 will support the RFID card. A counterweight 607 is rotatably connected to the surface of the turntable 604, and a baffle 608 is fixedly connected to the outer wall of the shielding shell 501. As the counterweight 607 rotates with the turntable 604, it will not press against the surface of the outer shell 1 and obstruct the normal rotation of the turntable 604 because the counterweight 607 can rotate along the surface of the turntable 604. When the counterweight 607 contacts the baffle 608, the turntable 604 will stop rotating, and the plane of the semi-circular rod 602 will be horizontal and facing upward. A hollow plate 610 is rotatably connected to the surface of the outer shell 1. A connecting plate 611 is slidably connected to the inner wall of the hollow plate 610. The connecting plate 611 is rotatably connected to the pedal 605. A flexible hose 612 is connected to the surface of the hollow plate 610. The flexible hose 612 is connected to the outer shell 1. When the pedal 605 is rotated, it will drive the connecting plate 611 to rotate. The connecting plate 611 will insert into the hollow plate 610 and compress the air inside the hollow plate 610. At this time, the air inside the hollow plate 610 will flow into the outer shell 1 through the flexible hose 612. Then the air will be discharged through the heat dissipation hole 4. Therefore, when the pedal 605 is stepped on, it will accelerate the air flow speed inside the outer shell 1, thereby dissipating heat from the electronic components inside the outer shell 1.

[0036] like Figure 9 and Figure 10 as well as Figure 11As shown, the reset plate 72 and the second spring 73 are both sleeved on the arc surface of the fixed rod 71. The reset plate 72 is slidably connected to the outer shell 1. The two ends of the second spring 73 are fixedly connected to the outer shell 1 and the reset plate 72, respectively. A block 74 is fixedly connected to the side wall of the outer shell 1. A screw 75 is internally threaded onto the block 74. A rectangular rod 76 is rotatably connected to one end of the screw 75. The rectangular rod 76 is slidably connected to the outer shell 1. An elastic strip 77 made of rubber is fixedly connected to the surface of the rectangular rod 76. When the user leaves the pedal 605, the second spring 73 begins to contract, and the reset plate 72 will drive the pedal 605 to rotate upward, thereby causing the pedal 605 to automatically reset. When the rotation speed of the semi-circular rod 602 needs to be controlled by adjusting the reset speed of the pedal 605, the screw 75 is rotated. The rotation of the screw 75 drives the rectangular rod 76 to move. The movement of the rectangular rod 76 compresses the elastic strip 77. Since the elastic strip 77 is pressed against the surface of the reset plate 72, the elastic strip 77 will deform under pressure. When the reset plate 72 slides upward, the elastic strip 77 will slow down the sliding speed of the reset plate 72 with its own friction. The greater the friction between the elastic strip 77 and the reset plate 72, the slower the sliding speed of the reset plate 72, thus preventing the RFID card from falling into the storage box 603 as soon as the user leaves the pedal 605. The elastic strip 77 has an arc-shaped cavity, and a rigid plate 79 is embedded in the elastic strip 77. The rigid plate 79 can make the pressure between the elastic strip 77 and the reset plate 72 uniform, thereby making the friction between the elastic strip 77 and the reset plate 72 uniform. A sealing plate 78 is fixedly connected to the upper surface of the reset plate 72. The sealing plate 78 is slidably connected to the outer shell 1. When the reset plate 72 slides, it will drive the sealing plate 78 to slide. The sealing plate 78 can block the second spring 73 and prevent foreign objects from falling into the second spring 73 and jamming the second spring 73.

[0037] Working principle: When the reader 3 is needed to read the RFID card, the user first stands on the pedal 605. The pedal 605 rotates downwards under pressure. During this process, the pedal 605 first squeezes the reset plate 72, causing it to slide downwards along the arc of the fixing rod 71 and stretch the second spring 73. The sliding of the reset plate 72 drives the sealing plate 78 to slide, which blocks the second spring 73, preventing foreign objects from falling into and jamming it. The rotation of the pedal 605 also drives the connecting plate 611 to rotate. The connecting plate 611 inserts into the hollow plate 610, compressing the air inside. The air inside the hollow plate 610 then flows into the outer casing 1 through the hose 612. Air is expelled through the heat dissipation hole 4, thus accelerating the airflow speed inside the housing 1 when the pedal 605 is stepped on, thereby dissipating heat from the electronic components inside the housing 1. When the pedal 605 rotates to a certain angle, it tightens the transmission belt 606. As the pedal 605 continues to rotate, the transmission belt 606 drives the turntable 604 to rotate. At this time, the protective cover 609 can prevent the transmission belt 606 from being touched and affecting its normal operation. The rotation of the turntable 604 drives the rotating rod 601 to rotate, and the rotation of the rotating rod 601 drives the semi-circular rod 602 to rotate, thereby adjusting the position of the semi-circular rod 602. As the counterweight 607 rotates with the turntable 604, since the counterweight 607 can rotate along the surface of the turntable 604, the counterweight... Block 607 will not press against the surface of the outer casing 1 and obstruct the normal rotation of the turntable 604. When the counterweight block 607 contacts the baffle 608, the turntable 604 will stop rotating. At this time, the plane of the semicircular rod 602 will be horizontally upward, and the user can then insert the RFID card into the shielding shell 501. During this process, the RFID card will first contact the conical surface of the pressure rod 505. The conical surface of the pressure rod 505 can guide the sliding path of the RFID card, making it easier for the user to insert the RFID card. After the RFID card is fully inserted, the semicircular rod 602 will support the RFID card. Under the influence of the gravity of the strip plate 506 and the triangular block 507, the triangular block 507 will press down on the slide plate 503, and the slide plate 503 will slide towards the card reader 3. 504, with the sliding of the slide plate 503, will cause the pressure rod 505 to slide. The pressure rod 505 will push the RFID card to stick to the surface of the card reader 3, making it convenient for the card reader 3 to read the RFID card. After use, the push frame 509 is pulled away from the shielding shell 501. The sliding of the push frame 509 will stretch the first spring 510, keeping the first spring 510 in a stretched state. When the push frame 509 slides to a certain position, it will contact the inner wall of the shielding shell 501, thus preventing the push frame 509 from being pulled out of the shielding shell 501. Then, the push frame 509 is released. The push frame 509 will slide quickly towards the RFID card with the help of the elastic force of the first spring 510. The push frame 509 will hit the RFID card, causing the RFID card to slide out of the shielding shell 501.The positioning plate 511 restricts the sliding path of the RFID card. The sliding of the push frame 509 also contacts the conical surface of the pressure rod 505, causing the pressure rod 505 to slide away from the reader 3, preventing it from further squeezing the RFID card and facilitating its sliding out of the shielding shell 501. The RFID card then contacts the friction pad 512, which cushions the card with its own friction, preventing it from falling. A triangular protrusion at the end of the push frame 509 that contacts the RFID card allows for pressing down on a thicker card and pushing it out of the shielding shell 501. When the RFID card is thinner, the flat end of the push frame 509 prevents the card from getting stuck between the push frame 509 and the reader 3.

[0038] When the client leaves pedal 605, the second spring 73 begins to contract, and the reset plate 72 causes pedal 605 to rotate upwards, thus automatically resetting pedal 605. The rotation of pedal 605 pulls the connecting plate 611 again, allowing air to flow into the hollow plate 610 through the one-way valve 613. As pedal 605 continues to rotate, the transmission belt 606 gradually loosens, and the counterweight 607, under its own weight, drives the turntable 604 to rotate in the opposite direction, thus rotating the plane of the semi-circular rod 602 to a vertical position. Therefore, if the client forgets to remove the pedal... When the RFID card is dispensed, it slides into the storage box 603, which collects and stores the RFID card to prevent it from being lost. When someone uses the card reader 3 again, the semi-circular rod 602 rotates back to the flat-up position. The semi-circular rod 602 and the storage box 603 work together to shield the RFID card in the storage box 603, preventing the information of the RFID card from being read. The shielding shell 501 can shield the radio waves emitted by the surrounding RFID cards.

[0039] When the rotation speed of the semi-circular rod 602 needs to be controlled by adjusting the reset speed of the pedal 605, the screw 75 is rotated. The rotation of the screw 75 will drive the rectangular rod 76 to move. The movement of the rectangular rod 76 will compress the elastic strip 77. Since the elastic strip 77 is pressed against the surface of the reset plate 72, the elastic strip 77 will be deformed under pressure. When the reset plate 72 slides upward, the elastic strip 77 will slow down the sliding speed of the reset plate 72 by its own friction. The greater the friction between the elastic strip 77 and the reset plate 72, the slower the sliding speed of the reset plate 72 will be. This will prevent the RFID card from falling into the storage box 603 as soon as the user leaves the pedal 605. During the sliding process of the reset plate 72, the rigid plate 79 can make the pressure between the elastic strip 77 and the reset plate 72 uniform, thereby making the friction between the elastic strip 77 and the reset plate 72 uniform.
