Description

Technical Field

[0001] This utility model relates to the field of RFID electronic tag technology, and in particular to an RFID electronic tag device that prevents detachment. Background Technology

[0002] Anti-detachment RFID electronic tag devices are devices that, based on traditional RFID electronic tags, are optimized in physical structure and upgraded in functional design to specifically prevent tags from being maliciously removed, accidentally detached, or illegally tampered with. They can maintain the advantages of non-contact identification and long-distance reading in RFID technology, while ensuring the stable binding of the tag to the identified object through the anti-detachment mechanism, thereby ensuring the continuity and reliability of data tracking.

[0003] Existing anti-detachment RFID electronic tag devices achieve anti-detachment through physical fixation, anti-tamper triggering, material optimization, and device design. Physically, high-strength adhesive and mechanical locking are used to enhance the bonding force. The anti-tamper mechanism includes a circuit loop, which triggers an abnormal signal upon detachment. The materials are selected to be tear-resistant and low-friction, and the structure is adapted to the carrier. The device scans regularly and uses a unique ID to identify detachment, which can prevent accidental detachment and malicious removal. It is suitable for logistics and medical scenarios.

[0004] However, due to the overemphasis on anti-detachment performance at the expense of replaceability, many of them use one-time strong adhesive, embedded injection molding or irreversible buckle fixation. If the label is damaged or needs to be updated after installation, removal will cause the label substrate to tear, the carrier to be damaged, or even the entire structure to be destroyed before replacement, which increases maintenance costs and limits the reuse of the equipment. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides an RFID electronic tag device that prevents detachment, aiming to improve the problem in the prior art where, if the tag is damaged or needs to be updated after installation, removal will cause the tag substrate to tear, the carrier to be damaged, or even require destruction of the entire structure to replace it.

Plastic films are fixedly connected to the four corners of the bottom of the base shell. Hollow columns are fixedly connected to the bottom of multiple plastic films, and suction cups are fixedly connected to the bottom of multiple hollow columns. A protective component is provided at the bottom of the base shell, and an adhesive dissolving component is provided inside the connecting column.

[0010] As a further description of the above technical solution:

[0011] The installation mechanism includes a label base, the bottom of which is fixedly connected to the top inner side of the label housing.

An installation component is provided inside the label housing.

[0012] As a further description of the above technical solution:

[0013] The switch assembly includes multiple hinges, with the top of each adjacent side of the multiple hinges fixedly connected to the left and right sides of the base top plate, the bottom right sides of the two left hinges fixedly connected to the same door panel, and the bottom left sides of the two right hinges fixedly connected to the top right side of the base housing.

[0014] As a further description of the above technical solution:

[0015] The fixing component includes two screws, the outer walls of which are threaded to the middle left side of the door panel. A fixing plate is fixedly connected to the inner left side of the base housing, and the outer walls of the two screws are threaded to the middle left side of the fixing plate.

[0016] As a further description of the above technical solution:

[0017] The protective component includes a waterproof housing, the top of which is fixedly connected to the bottom of the base housing, and a rubber bottom edge is fixedly connected to the bottom of the waterproof housing.

[0018] As a further description of the above technical solution:

[0019] The viscous dissolving component includes a cross, the left and right ends of which are fixedly connected to the inner bottom of the connecting column.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the magnetic rod is attracted to the magnetic base, causing the magnetic rod to slide into the magnetic base. The locking block moves with the magnetic rod and contacts the top plate of the base. The fixed column supports the limiting plate and contacts the magnetic rod. The locking block, the top plate of the base, the fixed column and the limiting plate work together to restrict the movement of the magnetic rod. After the label shell is rotated, the locking block and the top plate of the base work together to achieve a stable connection between the label shell and the base shell, effectively preventing the label shell from detaching from the base shell and ensuring the overall anti-drop performance of the device. At the same time, the label can be replaced better without damaging the label and the carrier.

[0024] 2. In this utility model, after removing the plastic sheet, pressing the base shell causes the hollow column to drive the suction cup to contact the object. Squeezing the suction cup releases air and achieves adsorption. At the same time, the sticky substance adheres to the object, and the protective component prevents liquid from entering. When separation is required, the adhesive dissolving component reduces the stickiness, and the plastic film is punctured to allow air to enter the suction cup to release the adsorption. This achieves a stable fixation between the base shell and the object, and the fixation can be released through specific operations, thus taking into account both anti-fall-off performance and the convenience of subsequent separation.

Detailed Implementation

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Reference Figure 1 , Figure 2 and Figure 3An embodiment of this utility model is provided: an RFID electronic tag device for preventing detachment, including a tag shell 1 and a base shell 2. A connecting mechanism 3 is provided at the bottom of the tag shell 1. The connecting mechanism 3 is used to fix the card holder with the RFID electronic tag on the base. An adhesive mechanism 4 is provided at the bottom of the base shell 2. The adhesive mechanism 4 is used to fix the base on the object. An installation mechanism 5 is provided on the top inner side of the tag shell 1.

[0035] The connecting mechanism 3 includes two magnetic rods 31, the tops of which are fixedly connected to the bottom of the label housing 1. A locking block 32 is fixedly connected to the top left side of the left magnetic rod 31. A base plate 33 is provided at the bottom of the label housing 1. A magnetic base 34 is slidably connected to the bottom of the magnetic rods 31. The bottom of the magnetic base 34 is fixedly connected to the inside of the base housing 2. Multiple fixing posts 35 are provided inside the magnetic base 34. The bottoms of the multiple fixing posts 35 are all fixedly connected to the inside of the base housing 2. The tops of the multiple fixing posts 35 are all fixedly connected to the same limiting plate 36. A switch assembly 37 is provided on the left side of the base plate 33. A fixing assembly 38 is provided on the left side of the base housing 2.

[0036] Specifically, the base shell 2 is fixed to the object by the adhesive mechanism 4. When the label shell 1 is connected to the base shell 2, the two magnetic rods 31 at the bottom of the label shell 1 move closer to the magnetic base 34, and a magnetic attraction is generated between the magnetic rods 31 and the magnetic base 34, causing the magnetic rods 31 to gradually slide into the magnetic base 34. During this process, the locking block 32 on the top left side of the left magnetic rod 31 moves with the magnetic rod 31 and contacts the left edge of the base top plate 33. Through the action of the locking block 32 and the base top plate 33, the vertical direction of the magnetic rod 31 is restricted. The multiple fixing posts 35 inside the magnetic base 34 limit the movement. Plate 36 forms a support, and limiting plate 36 contacts the top of magnetic rod 31. Through fixing post 35 and limiting plate 36, the movement of magnetic rod 31 in the lateral position is restricted. When magnetic rod 31 is fully inserted into magnetic base 34, by rotating label shell 1, the action of locking block 32 and base top plate 33 restricts the vertical movement of magnetic rod 31, thereby locking label shell 1 and base shell 2. Switch assembly 37 on the left side of base top plate 33 is used to switch base top plate 33. When switch assembly 37 is closed, it will be fixed by fixing assembly 38, achieving the overall anti-drop effect of the device.

[0037] Reference Figure 1 , Figure 4 and Figure 5The adhesive mechanism 4 includes a connecting post 41, the top of which is fixedly connected to the bottom of the base housing 2, an adhesive substance 42 is fixedly connected to the bottom of the connecting post 41, a plastic sheet 43 is fixedly connected to the bottom of the adhesive substance 42, plastic films 44 are fixedly connected to the four corners of the bottom of the base housing 2, hollow posts 45 are fixedly connected to the bottom of the multiple plastic films 44, suction cups 46 are fixedly connected to the bottom of the multiple hollow posts 45, a protective component 47 is provided at the bottom of the base housing 2, and an adhesive dissolving component 48 is provided inside the connecting post 41.

[0038] Specifically, during use, the base shell 2 is placed on the surface of the object. Pressing the base shell 2 causes the hollow columns 45 at the four corners of the bottom of the base shell 2 to move towards the object. The suction cups 46 at the bottom of the hollow columns 45 come into contact with the surface of the object. By squeezing the suction cups 46, the air between the suction cups 46 and the surface of the object is expelled. The plastic film 44 blocks the top of the hollow columns 45, preventing air from entering and causing the suction cups 46 to adhere to the surface of the object. At the same time, the adhesive substance 42 at the bottom of the connecting column 41 comes into contact with the surface of the object as the base shell 2 is pressed. The plastic sheet 43 protects the adhesive substance 42 before installation. During installation, the plastic sheet 43 is removed, and the adhesive substance 42 adheres to the surface of the object based on its own properties. The function of the disc 46 is to initially fix the base shell 2 to the object. When it is necessary to remove the base shell 2 from the object surface, the adhesive dissolving component 48 inside the connecting column 41 is activated. The adhesive dissolving component 48 acts on the adhesive substance 42, reducing the stickiness of the adhesive substance 42. At the same time, the plastic film 44 is punctured, allowing air to enter between the suction cup 46 and the object surface through the punctured plastic film 44 and the hollow column 45, releasing the suction state of the suction cup 46, realizing the separation of the adhesive substance 42 from the object surface and the separation of the suction cup 46 from the object surface, thereby allowing the base shell 2 to detach from the object surface. The protective component 47 protects the adhesive substance 42 and the suction cup 46 in use, preventing contact with foreign objects from affecting the fixing effect.

[0039] Reference Figure 2 , Figure 3 and Figure 6The mounting mechanism 5 includes a label base 51, the bottom of which is fixedly connected to the top inner side of the label housing 1. A label cover plate 52 is slidably connected to the outer wall of the label base 51. Two fixing grooves 53 are opened on the front and rear sides of the inside of the label housing 1. Pressure plates 54 are slidably connected between adjacent fixing grooves 53. An installation component 55 is provided inside the label housing 1. The switch component 37 includes multiple hinges 371. The top of adjacent sides of multiple hinges 371 are fixedly connected to the left and right sides of the base top plate 33. The bottom right side of the two left hinges 371 is fixedly connected to the same door panel 372. The bottom left side of the two right hinges 371 is fixedly connected to the top right side of the base housing 2. The fixing component 38 includes two screws 381. The outer walls of the two screws 381 are threadedly connected to the middle left side of the door panel 372. A fixing plate 382 is fixedly connected to the left side of the inside of the base housing 2. The outer walls of the two screws 381 are threadedly connected to the middle left side of the fixing plate 382.

[0040] Specifically, the RFID electronic tag is placed on the tag base 51, the bottom of which is fixed to the top inner side of the tag housing 1 to provide support for the electronic tag. The tag cover plate 52 is pushed to slide along the outer wall of the tag base 51 until it covers the electronic tag. The fixing grooves 53 on the front and rear sides inside the tag housing 1 act with the pressure plate 54. By sliding the pressure plate 54 in the fixing grooves 53, the position of the tag cover plate 52 is restricted. The mounting component 55 is activated to stably cover the tag cover plate 52 on the tag base 51, thus fixing the electronic tag inside the tag housing 1. When the tag housing 1 and the base are closed, the tag cover plate 52 is fixed to the tag base 51. When the shell 2 is connected, the base top plate 33 rotates through the hinges 371 on the left and right sides. The left hinge 371 drives the door panel 372 to rotate, so that the door panel 372 fits against the left side of the base shell 2. Rotate the screw 381 of the fixing component 38. The screw 381 moves along the thread in the middle of the left side of the door panel 372 and connects with the thread in the middle of the left side of the fixing plate 382 inside the base shell 2. Through the thread action of the screw 381, the door panel 372 and the fixing plate 382 are fixed. When it is necessary to unlock, rotate the screw 381 in the opposite direction to disengage it from the fixing plate 382.

[0041] Reference Figure 4 , Figure 5 and Figure 6The protective component 47 includes a waterproof housing 471, the top of which is fixedly connected to the bottom of the base housing 2. A rubber bottom edge 472 is fixedly connected to the bottom of the waterproof housing 471. The adhesive dissolving component 48 includes a cross 481, the left and right ends of which are fixedly connected to the bottom of the connecting column 41. A cylindrical block 482 is fixedly connected to the middle of the outer wall of the cross 481. A spherical block 483 is provided on the top of the cylindrical block 482. A dissolving agent bottle 484 is fixedly connected to the outer wall of the spherical block 483. The installation component 55 includes a baffle 551, the front and rear sides of which are slidably connected to the front and rear sides of the label housing 1. A slide 552 is provided on the right side of the label housing 1. The outer wall of the baffle 551 is slidably connected to the inside of the slide 552.

[0042] Specifically, the top of the waterproof outer shell 471 is fixed to the bottom of the base shell 2. The rubber bottom edge 472 of the waterproof outer shell 471 contacts the surface of the object. Through the action of the waterproof outer shell 471 and the rubber bottom edge 472, external liquid is prevented from entering the adhesive mechanism 4, thus protecting the adhesive mechanism 4. The left and right ends of the cross 481 are fixed to the inner bottom of the connecting column 41 to provide support for the cylindrical block 482. The cylindrical block 482 is fixed to the middle of the outer wall of the cross 481. The spherical plug 483 is placed on top of the cylindrical block 482. The dissolving agent bottle 484 is fixed to the spherical plug 483. When the viscous substance 42 needs to be dissolved, the outer wall of 83 pushes the dissolving agent bottle 484, causing the spherical block 483 to push against the cylindrical block 482, causing the spherical block 483 to detach from the dissolving agent bottle 484 and enter the interior of the dissolving agent bottle 484. The internal agent flows out and acts on the viscous substance 42. The front and rear sides of the baffle 551 are slidably connected to the front and rear sides of the interior of the label shell 1. The slide 552 on the right side of the label shell 1 provides a moving path for the baffle 551. When installing the electronic tag, the sliding baffle 551 moves along the slide 552, and the baffle 551 blocks the label cover plate 52.

[0043] Working principle: The RFID electronic tag is placed on the tag base 51. The bottom of the tag base 51 is fixed to the top inner side of the tag housing 1, providing support for the electronic tag. The tag cover plate 52 is pushed, causing it to slide along the outer wall of the tag base 51 until it covers the electronic tag. The fixing grooves 53 on the front and rear sides inside the tag housing 1 act with the pressure plate 54. By sliding the pressure plate 54 in the fixing grooves 53, the position of the tag cover plate 52 is restricted. The installation component 55 is activated, and the baffle 551 in the installation component 55 moves along the tag housing. 1. The slide rail 552 on the right moves, and the baffle 551 blocks the label cover 52. Through the action of the baffle 551 and the slide rail 552, the position of the label cover 52 is restricted, so that the label cover 52 is stably covered on the label base 51, thus fixing the electronic tag inside the label housing 1. After the installation of the electronic tag is completed, the base housing 2 is fixed to the object. The adhesive material 42 at the bottom of the connecting post 41 is protected by a plastic sheet 43 before installation. During installation, the plastic sheet 43 is removed, and the base housing 2 is placed on the surface of the object. Pressing the base shell 2 causes the hollow columns 45 at the four corners of the bottom of the base shell 2 to move towards the object. The suction cups 46 at the bottom of the hollow columns 45 come into contact with the object surface. By squeezing the suction cups 46, the air between the suction cups 46 and the object surface is expelled. The plastic film 44 blocks the top of the hollow columns 45, preventing air from entering and causing the suction cups 46 to adhere to the object surface. At the same time, the adhesive substance 42 at the bottom of the connecting column 41 comes into contact with the object surface as the base shell 2 is pressed. The adhesive substance 42 adheres to the object surface based on its own properties, thus achieving adhesion. The combined action of the material 42 and the suction cup 46 achieves the initial fixation between the base shell 2 and the object. During this process, the protective component 47 protects the adhesive material 42 and the suction cup 46 in use. The top of the waterproof shell 471 is fixed to the bottom of the base shell 2, and the rubber bottom edge 472 of the bottom of the waterproof shell 471 contacts the surface of the object. Through the action of the waterproof shell 471 and the rubber bottom edge 472, external liquids are prevented from entering the interior of the adhesive mechanism 4, thus preventing the adhesive material 42 and the suction cup 46 from contacting foreign objects and affecting the fixing effect.

[0044] Next, the label housing 1 and the base housing 2 are connected. The two magnetic rods 31 at the bottom of the label housing 1 move towards the magnetic base 34, generating magnetic attraction between them. This causes the magnetic rods 31 to gradually slide into the magnetic base 34. During this process, the locking block 32 on the top left side of the left magnetic rod 31 moves with it and contacts the left edge of the base top plate 33. The locking block 32 and the base top plate 33 restrict the vertical movement of the magnetic rod 31. Multiple fixing posts 35 inside the magnetic base 34 support the limiting plate 36, which contacts the top of the magnetic rod 31. The fixing posts 35 and the limiting plate 36 restrict the lateral movement of the magnetic rod 31. Once the magnetic rod 31 is fully inside the magnetic base 34, rotating the label housing 1 causes the locking block 32 to further interact with the base top plate 33, further restricting the vertical movement of the magnetic rod 31, thus achieving initial locking between the label housing 1 and the base housing 2. The label housing 1 and the base housing 2 are finally locked together by the switch assembly 37 and the fixing assembly 38. The base top plate 33 is rotated by the hinges 371 on the left and right sides. The two hinges 371 on the left side drive the door plate 372 to rotate, so that the door plate 372 fits against the left side of the base housing 2. The two screws 381 of the fixing assembly 38 are rotated, and the outer wall of the two screws 381 moves along the thread in the middle of the left side of the door plate 372. At the same time, the outer wall of the two screws 381 is threaded to the middle of the left side of the fixing plate 382 inside the base housing 2. The door plate 372 is fixed to the fixing plate 382 by the thread action of the screws 381, the door plate 372 and the fixing plate 382. When it is necessary to remove the device from the surface of the object, the label housing 1 is rotated in the opposite direction to release the restriction on the magnetic rod 31. The external force acts on the label housing 1, so that the two magnetic rods 31 overcome the magnetic force between themselves and the magnetic base 34 and slide out from the magnetic base 34, thereby separating the label housing 1 from the base housing 2.

[0045] Subsequently, remove the base housing 2 from the surface of the object, and rotate the two screws 381 in the opposite direction to detach the outer wall from the middle left side of the fixing plate 382, ​​and at the same time detach it from the middle left side of the door panel 372. At this time, the door panel 372 can be rotated through the two hinges 371 on the left side, and the base top plate 33 can be rotated through the hinges 371 on the left and right sides, thereby opening the base housing 2, activating the adhesive dissolving component 48 inside the connecting column 41, fixing the left and right ends of the cross 481 to the bottom inside the connecting column 41 to provide support for the cylindrical block 482, fixing the cylindrical block 482 to the middle of the outer wall of the cross 481, placing the spherical plug 483 on top of the cylindrical block 482, and fixing the dissolving agent bottle 484 to the outer wall of the spherical plug 483, pushing the dissolving agent... Bottle 484 causes the spherical block 483 to push against the cylindrical block 482. The spherical block 483 detaches from the dissolving agent bottle 484 and enters the interior of the dissolving agent bottle 484. The agent inside the dissolving agent bottle 484 flows out and acts on the viscous substance 42, reducing the viscosity of the viscous substance 42. At the same time, the plastic film 44 is punctured, allowing air to pass through the punctured plastic film 44 and the hollow column 45, allowing air to enter between the suction cup 46 and the object surface, releasing the suction state of the suction cup 46. Through the action of the viscous dissolving component 48 and the air entering the suction cup 46, the viscous substance 42 is separated from the object surface and the suction cup 46 is separated from the object surface, thereby causing the base shell 2 to detach from the object surface, completing the removal of the entire device from the object surface.

Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
