Description

Technical Field

[0001] This utility model relates to the field of RFID electronic tag technology, specifically a waterproof RFID electronic tag. Background Technology

[0002] RFID electronic tags, also known as radio frequency tags, transponders, or data carriers; readers, also known as reading devices, scanners, reader heads, communicators, or readers / writers, achieve spatial coupling of radio frequency signals between electronic tags and readers through coupling elements. Within the coupling channel, energy transfer and data exchange are realized according to timing relationships. In the past, electronic tags did not have waterproof functions, making them susceptible to moisture or water during use, which could lead to the electronic tags failing to function properly.

[0003] Patent document CN220271921U discloses a waterproof RFID electronic tag, including a first waterproof membrane, a tag body, a second waterproof membrane, a water-absorbing and waterproof structure, and a sealing and waterproof structure. The tag body is located on the upper surface of the first waterproof membrane. The size of the tag body is smaller than the first and second waterproof membranes. A rectangular first adhesive layer is coated around the tag body on the upper surface of the first waterproof membrane. The second waterproof membrane covers the upper surface of the tag body. This invention further improves the overall waterproof effect of the tag body, thereby extending its service life. Furthermore, in the event of accidental damage to the waterproof membrane, the tag body can be easily separated from the membrane and removed for re-wrapping and reuse, effectively avoiding unnecessary losses and waste. Overall, it has high practicality. However, in this technical solution, the connection between the first and second waterproof membranes is exposed, making it prone to damage and leakage. Summary of the Invention

[0004] In view of the shortcomings of the existing technology, this utility model provides a waterproof RFID electronic tag, which solves the problem of poor waterproof effect mentioned in the background technology.

[0005] Technical solution

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a waterproof RFID electronic tag, including a tag body, the front and rear sides of the tag body are covered with waterproof membranes, the front and rear waterproof membranes are bonded together, the front and rear waterproof membranes are folded backward to form creases, and an adhesive film covering the creases is bonded to the back of the waterproof membranes.

[0007] Furthermore, at least one end and at most three ends of the waterproof membrane on both the front and back sides are connected to each other before bonding.

[0008] Furthermore, the two ends of the waterproof membrane on the front and back sides are connected to form a sleeve, and the label body is placed in the middle of the sleeve.

[0009] Furthermore, the adhesive film has protrusions on all four sides, which do not contact each other, and the protrusions are bent forward to adhere to the waterproof film on the front side.

[0010] Furthermore, it also includes a sealing ring, which is distributed along the edge of the label body. The sealing ring is located on the outermost layer, with part of the sealing ring located on the front side of the label body and part located on the rear side of the label body.

[0011] Furthermore, adhesive layers are provided on both sides of the adhesive film, and a covering layer is provided on the side of the adhesive film away from the label body to prevent the adhesive layers from being exposed.

[0012] Furthermore, the covering layer has an extension and a fracture line of the same size as the label body.

[0013] The beneficial effects of this utility model are as follows:

[0014] 1. This waterproof RFID electronic tag has the tag body placed between two waterproof membranes. The waterproof membranes cover the tag body, and after covering, the tag body is bent backward to form a crease. The crease is covered by an adhesive film, so that the waterproof membrane and adhesive film together form a closed cavity for the tag body, thereby achieving a waterproof effect.

[0015] 2. This waterproof RFID electronic tag has an extension in its cover layer, and the cover layer has a tear the same size as the tag body. This design facilitates the separation of the cover layer from the adhesive film, and the tear allows the cover layer to separate into two parts. One part exposes the adhesive portion, while the other part folds along with the adhesive film. This design makes it easier to fold the adhesive film. Attached Figure Description

[0022] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] See Figures 1-5 A waterproof RFID electronic tag includes a tag body 1, with waterproof membranes 2 covering the front and back sides of the tag body 1. The front and back waterproof membranes 2 are bonded together. An adhesive layer is provided on one side of the waterproof membrane 2. The tag body 1 is connected to the two sides of the waterproof membrane 2 by compression. Alternatively, the waterproof membrane 2 does not have an adhesive layer, but the front and back waterproof membranes 2 are folded backward to form creases 3 by heat pressing. An adhesive film 4 is bonded to the back of the waterproof membrane 2 to cover the creases 3. By folding the waterproof membrane 2 backward to form creases 3 and covering the creases 3 with the adhesive film 4, water leakage from the creases 3 can be prevented.

[0024] The waterproof membrane 2 on both the front and back sides has at least one end and at most three ends connected to each other before bonding. This arrangement can reduce the gaps formed by the connection of the waterproof membrane 2, thereby reducing the possibility of leakage.

[0025] The waterproof membranes 2 on the front and back sides are connected at both ends to form a sleeve. The label body 1 is placed in the middle of the sleeve. This design allows the creases 3 to be located on the corresponding sides, thereby preventing adjacent creases 3 from being squeezed together and causing the edges to curl and leak.

[0026] The four sides of the adhesive film 4 form protrusions 5. The protrusions 5 do not contact each other. The protrusions 5 are bent forward and bonded to the waterproof film 2 on the front side. By setting the protrusions 5, the contact area with the waterproof film 2 can be increased, thereby preventing the adhesive film 4 from falling off.

[0027] It also includes a sealing ring 6, which is distributed along the edge of the label body 1. The sealing ring 6 itself is a plastic film with adhesive material. The sealing ring 6 is located on the outermost layer, with part of the sealing ring 6 located on the front side of the label body 1 and part of the sealing ring 6 located on the rear side of the label body 1. By setting the sealing ring 6, protection can be formed, thereby preventing water leakage.

[0028] Adhesive layers are provided on both sides of the adhesive film 4. A cover layer 7 is provided on the side of the adhesive film 4 away from the label body 1 to prevent the adhesive layer from being exposed. By providing the cover layer 7, it can be separated from the adhesive film 4 during use, thereby ensuring that the adhesive film 4 can adhere to the outside more effectively.

[0029] The cover layer 7 has an extension 8 and a tear 9 of the same size as the label body 1. This design facilitates the separation of the cover layer 7 from the adhesive film 4 and allows the cover layer 7 to be separated into two parts by the tear 9. One part exposes the adhesive part, while the other part is folded with the adhesive film 4. This design makes it easier to fold the adhesive film 4.

[0030] In use, the label body 1 is placed between two waterproof membranes 2, and the label body 1 is covered by the waterproof membranes 2. After covering, the label body 1 is bent to the rear to form a crease 3. The crease 3 is covered by the adhesive membrane 4. Thus, the waterproof membranes 2 and the adhesive membrane 4 together form a closed cavity for the label body 1, thereby achieving a waterproof effect.

[0031] It should be noted that in this paper, relational terms such as first and second are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
