Abstract
Description
Technical Field
[0001] This utility model belongs to the field of electronic tag technology, and in particular relates to an anti-tampering RFID electronic tag. Background Technology
[0002] RFID tags are the "digital ID cards" for asset digitization in the Internet of Things era. Their diverse technical characteristics and scenario adaptability make them a core tool in fields such as smart manufacturing and smart healthcare.
[0003] The utility model with publication number CN216486472U discloses an RFID electronic tag for tamper-proof use, including an outer protective shell, a storage plate inside the outer protective shell, sliders fixed on both sides of the storage plate, a storage groove inside the storage plate, a connecting post on the front end of the storage groove, a connecting plate fixed on the rear end of the connecting post, and two springs B located inside the storage plate on the rear end of the connecting plate.
[0004] The aforementioned application document suggests adding an outer protective shell to the electronic tag, which provides some protection. However, its overall tamper-proof performance is poor, and it's possible for others to pull the tab and tamper with the tag. Utility Model Content
[0005] The purpose of this invention is to provide an tamper-proof RFID electronic tag that solves the existing problems.
[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:
[0007] This utility model relates to an anti-tamper RFID electronic tag, comprising a mounting box, a transparent cover at the front end of the mounting box, a mounting plate inserted inside the mounting box, a pull ring fixedly connected to the top of the mounting plate, an electronic tag body at the front end of the mounting plate, an anti-tamper fixing mechanism inside the mounting box, and a speed control mechanism on the side of the mounting plate; the anti-tamper fixing mechanism includes a groove and a slot, the groove being formed on the inner side wall of the mounting box, a slider slidably connected inside the groove, a telescopic spring being provided inside the slider, an arc-shaped block being elastically connected inside the slider via the telescopic spring, a threaded rod being rotatably connected to the end of the slider away from the arc-shaped block, a hexagonal groove being formed at the end of the threaded rod away from the slider, a hexagonal prism being inserted inside the hexagonal groove, a rotating block being fixedly connected to the end of the hexagonal prism away from the hexagonal groove, and a slot being formed on the side of the mounting box.
[0008] Furthermore, in the initial state, one-third of the arc-shaped block is located inside the slot, and the arc surface of the arc-shaped block faces the top of the mounting box. The arc-shaped block is stuck in the slot, preventing the mounting plate from moving upward and leaving the mounting box. When the arc surface of the arc-shaped block is squeezed, it will move into the slider.
[0009] Furthermore, the depth inside the slider is greater than the lateral length of the arc-shaped block, and the size of the transparent cover is greater than the size of the electronic tag body. The arc-shaped block can be completely retracted into the slider, and the electronic tag body can be used normally through the transparent cover.
[0010] Furthermore, the threaded rod is threaded to the inner wall of the groove, and the surface of the rotating block is provided with anti-slip texture. When the threaded rod rotates, it can drive the slider to move laterally in the groove, and the anti-slip texture can prevent the hand from slipping when rotating the rotating block.
[0011] Furthermore, the speed control mechanism includes a connecting frame, which is fixedly connected to the side of the mounting plate. A rotating wheel is rotatably connected to the inner side of the connecting frame. A circular groove is formed on the surface of the rotating wheel. A compression spring is provided inside the circular groove. A friction block is elastically connected inside the circular groove through the compression spring.
[0012] Furthermore, the side of the rotating wheel away from the mounting plate abuts against the inner wall of the mounting box. When the mounting plate moves vertically inside the mounting box, the rotating wheel will rub against the inner wall of the mounting box, thus causing it to rotate.
[0013] Furthermore, in the initial state, the friction block is completely inside the circular groove, and the elastic force of the compression spring is greater than the weight of the friction block, so the weight of the friction block will not cause it to move out of the circular groove.
[0014] Furthermore, the friction block is made entirely of rubber, and the end of the friction block away from the compression spring is uneven. When the uneven end of the rubber friction block comes into contact with the inner wall of the mounting box, it will generate greater resistance.
[0015] This utility model has the following beneficial effects:
[0016] 1. This utility model, by setting an anti-disassembly fixing mechanism, achieves the following: when the mounting plate is inserted into the mounting box, the arc-shaped block will automatically lock into the slot, preventing the mounting plate from moving upward and leaving the mounting box. The electronic tag body can be used normally through the transparent cover. Afterward, the rotating block can be removed for storage, preventing other personnel from rotating the threaded rod to drive the arc-shaped block out of the slot, thus preventing other personnel from disassembling the electronic tag body without authorization.
[0017] 2. This utility model, by setting a speed control mechanism, achieves the goal of slowing down the downward movement speed of the mounting plate during the process of inserting the mounting plate into the mounting box through the cooperation of components such as the connecting frame, rotating wheel, and friction block, so as to prevent the mounting plate from moving downward too fast and causing an impact that could damage the electronic tag body.
[0018] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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 skilled in the art without creative effort are within the protection scope of the present utility model.
[0029] Please see Figure 1-6 This utility model is an anti-tampering RFID electronic tag, including a mounting box 1, a transparent cover 2 at the front end of the mounting box 1, a mounting plate 3 inserted inside the mounting box 1, a pull ring 4 fixedly connected to the top of the mounting plate 3, an electronic tag body 5 at the front end of the mounting plate 3, an anti-tampering fixing mechanism 6 inside the mounting box 1, and a speed control mechanism 7 on the side of the mounting plate 3; the anti-tampering fixing mechanism 6 includes a groove 61 and a slot 69, the groove 61 is formed on the inner side wall of the mounting box 1, a slider 62 is slidably connected inside the groove 61, a telescopic spring 63 is formed inside the slider 62, an arc-shaped block 64 is elastically connected inside the slider 62 through the telescopic spring 63, a threaded rod 65 is rotatably connected to the end of the slider 62 away from the arc-shaped block 64, a hexagonal groove 66 is formed at the end of the threaded rod 65 away from the slider 62, a hexagonal column 67 is inserted inside the hexagonal groove 66, a rotating block 68 is fixedly connected to the end of the hexagonal column 67 away from the hexagonal groove 66, and a slot 69 is formed on the side of the mounting box 1.
[0030] As shown in the figure, in the initial state, one-third of the arc-shaped block 64 is located inside the slot 69, and the arc surface of the arc-shaped block 64 faces the top of the mounting box 1. The arc-shaped block 64 is stuck in the slot 69, which prevents the mounting plate 3 from moving upward and leaving the mounting box 1. When the arc surface of the arc-shaped block 64 is squeezed, it will move into the slider 62.
[0031] As shown in the figure, the depth inside the slider 62 is greater than the horizontal length of the arc block 64, and the size of the transparent cover 2 is greater than the size of the electronic tag body 5. The arc block 64 can be completely retracted into the slider 62, and the electronic tag body 5 can be used normally through the transparent cover 2.
[0032] As shown in the figure, the threaded rod 65 is threaded to the inner wall of the groove 61, and the surface of the rotating block 68 is provided with anti-slip texture. When the threaded rod 65 rotates, it can drive the slider 62 to move laterally in the groove 61. The anti-slip texture can prevent the hand from slipping when rotating the rotating block 68.
[0033] As shown in the figure, the speed control mechanism 7 includes a connecting frame 71, which is fixedly connected to the side of the mounting plate 3. A rotating wheel 72 is rotatably connected to the inner side of the connecting frame 71. A circular groove 73 is opened on the surface of the rotating wheel 72. A compression spring 74 is installed inside the circular groove 73. A friction block 75 is elastically connected inside the circular groove 73 through the compression spring 74.
[0034] As shown in the figure, the side of the rotating wheel 72 away from the mounting plate 3 abuts against the inner wall of the mounting box 1. When the mounting plate 3 moves vertically inside the mounting box 1, the rotating wheel 72 will rub against the inner wall of the mounting box 1 and thus rotate.
[0035] As shown in the figure, the friction block 75 is initially completely inside the circular groove 73, and the elastic force of the compression spring 74 is greater than the weight of the friction block 75. The weight of the friction block 75 will not cause it to move out of the circular groove 73.
[0036] As shown in the figure, the friction block 75 is made of rubber, and the end of the friction block 75 away from the compression spring 74 is uneven. When the uneven end of the rubber friction block 75 comes into contact with the inner wall of the mounting box 1, it will generate greater resistance.
[0037] One specific application of this embodiment is as follows: During installation, the mounting plate 3 is inserted into the mounting box 1. Initially, the arc surface of the arc-shaped block 64 is compressed and retracts into the slider 62, compressing the telescopic spring 63. When the mounting plate 3 is fully inserted into the mounting box 1, the slot 69 and the groove 61 coincide. At this time, the telescopic spring 63 rebounds, causing the arc-shaped block 64 to be inserted into the slot 69. At this point, the mounting plate 3 can no longer move upwards and leave the mounting box 1. The electronic tag body 5 can be used normally through the transparent cover 2. The rotating block 68 can be pulled out for storage, preventing other personnel from rotating the threaded rod 65 to move the arc-shaped block 64 out of the slot 69. When it is necessary to remove the electronic tag body 5, the hexagonal prism 6 on the side of the rotating block 68 is removed. 7. Insert the hexagonal slot 66 and rotate the rotating block 68, thereby driving the threaded rod 65 to rotate. The rotation of the threaded rod 65 can drive the slider 62 to move, causing the arc-shaped block 64 to leave the slot 69. Then, the mounting plate 3 can be pulled upward and away from the mounting box 1 by the pull ring 4. During the process of inserting the mounting plate 3 into the mounting box 1, when the insertion speed is fast, the rotating wheel 72 will rotate rapidly due to rapid friction with the inner wall of the mounting box 1. The centrifugal force generated by the rapid rotation of the rotating wheel 72 will move the friction block 75 out of the circular slot 73. At this time, the uneven end of the friction block 75 contacts the inner wall of the mounting box 1, thereby generating greater resistance to prevent the mounting plate 3 from moving downward too fast and causing an impact that could damage the electronic tag body 5.
