Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic tag technology, specifically to an RFID sample tag suitable for waterway engineering testing and inspection institutions. Background Technology
[0002] Testing and inspection in waterway engineering typically includes raw material testing, component testing, and engineering entity testing. Test samples are usually attached with sample tags containing information such as sample name, sample number, sampling location, and sampling time. With the development of RFID technology, its non-contact identification, rapid reading, large-capacity data storage, and high security features provide new solutions for sample management in waterway engineering testing and inspection organizations.
[0003] However, existing RFID tags only rely on a single protective film or a protective film combined with other waterproof layers for waterproofing, or simply provide a seal for the chip. The sealing effect is not ideal, and the chip is easily damaged by moisture, thus reducing the lifespan of the RFID tags. Utility Model Content
[0004] In view of this, the purpose of this utility model is to provide an RFID sample tag suitable for waterway engineering testing and inspection institutions. This RFID electronic tag can provide multiple layers of sealing protection for the chip, so as to solve the technical problems described in the background art.
[0005] This utility model is achieved through the following technical solution:
[0006] An RFID sample tag suitable for water transport engineering testing and inspection institutions includes a panel and a base plate arranged vertically. The base plate and the panel have openings facing upward and downward respectively on opposite sides, and an RFID chip is installed in both openings.
[0007] The bottom end face of the panel is integrally formed with a retaining ring, and the top end face of the substrate is provided with a retaining groove A that engages with the retaining ring, and a sealing ring is installed on the bottom wall of the retaining groove A.
[0008] The slot A divides the top end face of the substrate into two parts, forming an outer ring surface and an inner ring surface. The inner ring surface protrudes upward to form a protrusion. A slot B is provided on the top inner wall of the receiving cavity in the panel, and the protrusion extends into the slot B.
[0009] Furthermore, waterproof layer A and waterproof layer B are respectively fixed on the top and bottom inner walls of the two accommodating cavities, and the shape of the waterproof layer is adapted to the internal space of the accommodating cavity;
[0010] The waterproof layer A and the waterproof layer B are respectively provided with mounting grooves on opposite sides, and the RFID chip is installed in the space formed by the two mounting grooves.
[0011] Furthermore, the bottom of the waterproof layer A is integrally formed with several positioning posts, and the surface of the waterproof layer B is provided with several positioning holes that are inserted and matched with the positioning posts.
[0012] Furthermore, two opposing inner walls of the slot A are respectively protruding to form a locking block, and the side of the locking ring is provided with a plurality of locking grooves C that engage with the locking block.
[0013] Furthermore, the bottom surface of the card block is higher than the top surface of the sealing ring.
[0014] Furthermore, corner protectors are provided at the four corners of the perimeter of both the panel and the substrate.
[0015] Furthermore, the outer surfaces of the panel and the substrate are sprayed with polyurethane to form a polyurethane coating on their outer surfaces.
[0016] The beneficial effects of this utility model are as follows:
[0017] 1. This utility model improves the sealing and waterproof performance of the substrate and the panel for the RFID chip encapsulation by using the retaining ring to cooperate with the slot A and installing a sealing ring at the connection between the retaining ring and the slot A to form a sealing structure, thereby extending the service life of the RFID electronic tag.
[0018] Secondly, the protrusion, in conjunction with the slot B, can further serve to block water and achieve multiple layers of sealing protection, reducing the possibility of moisture entering the receiving cavity through the connection between the retaining ring and the slot A, thereby further improving the sealing effect between the substrate and the panel.
[0019] 2. When the RFID chip is encapsulated in the cavity between the substrate and the panel, the RFID chip is first encapsulated in the two thinner waterproof layers by bonding with the upper and lower waterproof layers, and then encapsulated in the substrate and the panel, thereby further improving the waterproof effect of the RFID chip.

Detailed Implementation
[0027] Typical embodiments embodying the features and advantages of this utility model will be specifically described in the following description. It should be understood that this utility model can have various variations in different embodiments, all of which do not depart from the scope of this utility model, and the descriptions and illustrations therein are for illustrative purposes only and not intended to limit this utility model.
[0028] In the description of this application, the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are used only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the structure referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this application.
[0029] Please see Figures 1 to 4 This utility model provides a technical solution: an RFID sample tag suitable for water transport engineering testing and inspection institutions, including a panel 2 and a substrate 1 arranged vertically. In this utility model, both the panel 2 and the substrate 1 are elongated. The tag can be designed into other sizes and shapes, such as circles, according to the actual needs of the water transport engineering testing and inspection institutions. Adhesive tape or other adhesives can be provided on the substrate 1 to facilitate pasting the tag onto the sample.
[0030] Secondly, considering the special environment of waterway engineering testing (such as high humidity, salt spray corrosion, and possible underwater use), the panel 2 and the substrate 1 are made of polyurethane material with certain flexibility and sealing properties to ensure that the RFID sample tag can maintain good performance in complex environments (the polyurethane material itself has little impact on RFID signals).
[0031] Meanwhile, the outer surfaces of the panel 2 and the substrate 1 are sprayed with polyurethane to form a polyurethane coating on their outer surfaces. The coating thickness is no more than 0.1 to 0.2 mm, thereby providing excellent waterproof, moisture-proof and weather-resistant properties for RFID sample tags.
[0032] Corner guards 9 are provided at the four corners of the periphery of the panel 2 and the substrate 1. The corner guards 9 are made of flexible material to reduce the risk of damage to the label during transportation and storage.
[0033] Please see Figure 4 and Figure 5 The substrate 1 and the panel 2 have openings facing upward and downward respectively on opposite sides of receiving cavities 3. An RFID chip 4 is installed in both receiving cavities 3. The RFID chip 4 is a high-performance, low-power RFID chip with a large capacity data storage function. It can record detailed information of the sample, such as name, specifications, source and testing date. The information recorded on the RFID chip 4 can be viewed through a reader. The application of the RFID chip 4 is relatively mature in the existing technology, and will not be described in detail here.
[0034] Secondly, in order to ensure the stable transmission of RFID signals in complex environments, special materials that are corrosion-resistant and high-temperature resistant are selected for the antenna to adapt to the working environment of waterway engineering testing and inspection institutions.
[0035] Please see Figure 2 , Figure 4 and Figure 5 The bottom end face of the panel 2 is integrally formed with a retaining ring 21, which has a rectangular ring structure. The top end face of the substrate 1 is provided with a rectangular ring groove A11 that engages with the retaining ring 21. The retaining ring 21 and the groove A11 are interference-fitted. The panel 2 can be fixed together with the substrate 1 by inserting the retaining ring 21 into the groove A11. A sealing ring 5 is installed on the bottom wall of the groove A11. The shape of the sealing ring 5 is adapted to the bottom space of the groove A11 to improve the sealing performance of the panel 2 and the substrate 1 for the encapsulation of the RFID chip 4.
[0036] Please see Figure 2On the two inner walls opposite to each other of the card slot A11, card blocks 15 are respectively protruding. The side of the card ring 21 is provided with several card slots C23 that engage with the card blocks 15. The card blocks 15 and the card slots C23 are also interference fit, which further improves the stability of the connection between the substrate 1 and the panel 2, thereby ensuring the packaging effect of the RFID chip 4.
[0037] The bottom surface of the locking block 15 is higher than the top surface of the sealing ring 5. The locking block 15 can limit the upward movement of the sealing ring 5, so that the sealing ring 5 is stably installed at the bottom of the slot A11.
[0038] Please see Figure 2 and Figure 4 The card slot A11 divides the top end face of the substrate 1 into two parts to form an outer ring surface 12 and an inner ring surface 13 respectively. Adhesive can be applied to the outer ring surface 12 to fix the substrate 1 to the panel 2 and ensure the encapsulation effect.
[0039] The inner ring surface 13 protrudes upward to form a protrusion 14. A slot B22 is provided on the top inner wall of the receiving cavity 3 of the panel 2. The top of the protrusion 14 extends into the slot B22. The cooperation between the protrusion 14 and the slot B22 can further play a role in blocking water and reducing the possibility of moisture entering the receiving cavity 3 through the connection between the retaining ring 21 and the slot A11, thereby further improving the sealing effect between the substrate 1 and the panel 2.
[0040] Please see Figures 4 to 6 Waterproof layer A6 and waterproof layer B7 are respectively fixed on the top inner wall of the cavity 3 in panel 2 and the bottom inner wall of the cavity 3 in substrate 1. The shape of the waterproof layer is adapted to the internal space of the cavity 3. The waterproof layer is made of polyurethane or epoxy resin material.
[0041] The waterproof layer A6 and the waterproof layer B7 are respectively provided with mounting grooves 8 on opposite sides. The RFID chip 4 is installed in the space formed by the two mounting grooves 8. When the RFID chip 4 is encapsulated in the receiving cavity 3 between the substrate 1 and the panel 2, the RFID chip 4 is encapsulated in two thinner waterproof layers by the upper and lower waterproof layers being bonded to each other, thereby further improving the waterproof effect of the RFID chip 4.
[0042] Please see Figure 5 and Figure 6The bottom of the waterproof layer A6 is integrally formed with several positioning posts 61, and the surface of the waterproof layer B7 is provided with several positioning holes 71 that are inserted and cooperate with the positioning posts 61. The positioning posts 61 cooperate with the positioning holes 71 so that the waterproof layer A6 and the waterproof layer B7 can be inserted and fixed together, and the positioning posts 61 are conducive to the positioning and installation of the RFID chip 4.
[0043] Finally, it should be noted that the above embodiments are only preferred embodiments of this utility model and should not be used to limit the scope of protection of this utility model. Any non-substantial changes and substitutions made by those skilled in the art based on this utility model shall fall within the scope of protection claimed by this utility model.
