Description

Technical Field

[0001] This utility model belongs to the field of electronic tag technology, specifically relating to a fragile electronic tag based on paper substrate. Background Technology

[0002] With the rapid development of the Internet of Things, supply chain management, and anti-counterfeiting traceability technologies, Radio Frequency Identification (RFID) electronic tags have been widely used due to their advantages such as non-contact operation, rapid batch reading, and large data storage capacity. Especially in fields such as product anti-counterfeiting, asset tracking, and ticket management, increasingly higher requirements are placed on the anti-transfer and anti-tampering performance of electronic tags. Fragile RFID tags are an important solution to meet this anti-transfer requirement. Their core design concept is that when the tag is attempted to be peeled off from the surface of the attached object, the tag's antenna or chip connection structure will undergo irreversible breakage or damage, resulting in permanent failure of the tag's function, thus effectively preventing the tag from being illegally and intact transferred to counterfeit or substandard goods. Patent document CN108510042A discloses a fragile electronic tag, which is attached to a paper surface and includes a substrate. The substrate includes an upper face paper layer and a lower first thin film layer. The first thin film layer has a tag antenna and a tag chip, and the tag chip is electrically connected to the tag antenna. At least one fixing area and at least one transfer area are provided under the substrate. The technical solution of this invention sets the tag antenna and tag chip in different areas, and by using different adhesive structures in the fixing area and the transfer area, the tag antenna and tag chip have different bonding states. This allows the tag antenna to break while the transfer area is being destroyed, achieving a fragile tag effect without damaging the paper itself. However, the above patent has the following problems in use: it is not suitable for pasting electronic tags on the surface of columnar objects, affecting the surface quality of the product and making it impossible to fix the electronic tags. Utility Model Content

[0003] Therefore, this utility model aims to solve the problem in the prior art that it is not suitable to stick electronic tags on the surface of columnar objects, which affects the surface quality of the product and makes it impossible to fix the electronic tags.

[0004] Therefore, the technical solution adopted is a fragile electronic tag based on paper substrate, comprising a paper substrate, a chip and an antenna disposed inside the paper substrate, two antennas located on both sides of the chip, the chip and the antennas being connected, an indentation provided in the middle of the paper substrate, one end of the paper substrate being connected to one end of a first flexible strip, the other end of the first flexible strip being provided with multiple serrations along its length, the other end of the paper substrate being connected to one end of a second flexible strip, the other end of the second flexible strip being provided with a fixing block, the fixing block being provided with a channel, the inner wall of the channel being provided with a groove, one end of a spring being connected to the bottom wall of the groove, the other end of the spring being connected to one end of a clamping block, the other end of the clamping block extending into the channel.

[0005] Preferably, the cross-section of the serrations is a right-angled triangle.

[0006] Preferably, the clamping block is rectangular.

[0007] Preferably, the end of the first flexible strip away from the paper substrate is chamfered.

[0008] Preferably, the paper substrate is rectangular.

[0009] Preferably, a tear-off marking line is provided at the middle position of the concave portion.

[0010] The advantages of this utility model are as follows: the paperboard is fitted onto the fixing rod, and the serrated end of the first flexible strip is passed through the channel of the fixing block, so that the clamping block is clamped on the two adjacent serrations, making the electronic tag securely fixed. Since the first flexible strip cannot be pulled out in reverse, the electronic tag can only be removed by tearing the electronic tag from the tear mark in the concave part, thereby making the electronic tag ineffective and improving the scope of use of the electronic tag.

[0011] Other features and advantages of this invention will be set forth in the description which follows, and will be apparent in part from the description, or may be learned by practicing the invention. The objects and other advantages of this invention can be realized and obtained by means of the structures particularly pointed out in the written description and the accompanying drawings.

[0019] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0020] It should be noted that when a component is referred to as being "fixed to" or "set on" another component, it can be directly or indirectly attached to that other component. When a component is referred to as being "connected to" another component, it can be directly or indirectly connected to that other component.

[0021] It should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", and "outer" indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element 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 utility model.

[0022] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0023] This utility model provides a fragile electronic tag based on a paper substrate, such as Figure 1-4As shown, the device includes a paper substrate 1, within which a chip 2 and an antenna 3 are disposed. Two antennas 3 are located on either side of the chip 2, and the chip 2 is connected to the antennas 3. A recessed portion 4 is provided in the middle of the paper substrate 1. One end of the paper substrate 1 is connected to one end of a first flexible strip 5. The other end of the first flexible strip 5 has multiple serrations 7 along its length. The other end of the paper substrate 1 is connected to one end of a second flexible strip 6. A fixing block 8 is provided at the other end of the second flexible strip 6. A channel 9 is provided on the fixing block 8, and a groove 10 is provided on the inner wall of the channel 9. One end of a spring 11 is connected to the bottom wall of the groove 10, and the other end of the spring 11 is connected to one end of a clamping block 12. The other end of the clamping block 12 extends into the channel 9. The cross-section of the serrations 7 is a right-angled triangle, which allows the first flexible strip 5 to be more easily inserted into the channel 9 of the fixing block 8 and prevents it from falling out. The clamping block 12 is cuboid in shape, and the contact surface between the clamping block and the serrations 7 is large, resulting in a more secure fixation. The end of the first flexible strip 5 away from the paper substrate 1 is chamfered. The paper substrate 1 is rectangular. A tear mark 13 is provided in the middle of the recess 4 to facilitate personnel to damage the electronic tag and disable it.

[0024] The working principle and beneficial technical effects of the above technical solution are as follows: When it is necessary to fix the electronic tag to the rod-shaped object, the paper base plate 1 is fitted onto the fixing rod, and the end of the first flexible strip 5 with serrations 7 is passed through the channel 9 of the fixing block 8, so that the clamping block 12 is clamped into the two adjacent serrations 7, making the electronic tag securely fixed. Since the first flexible strip 5 cannot be pulled out in reverse, to remove the electronic tag, it can only be torn from the tear mark 13 of the concave part 4, thereby making the electronic tag ineffective and improving the scope of use of the electronic tag.

[0025] Obviously, those skilled in the art can make various modifications and variations to this utility model without departing from its spirit and scope. Therefore, if these modifications and variations fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.
