Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electronic tags, in particular to a plug-in RFID electronic tag. Background Art
[0002] With the increasing maturity of RFID technology and the diversification of RFID electronic tag application scenarios, in order to meet different usage scenarios, the appearance of RFID electronic tags is becoming more and more diversified. Among them, the RFID electronic tag encapsulates the RFID chip in a pin or a screw, which can be easily fixed on the rough or irregular surface of an object and can also be used as a fastener. In order to ensure smooth communication between the RFID electronic tag chip and the reader, the encapsulation shell of the RFID electronic tag is usually made of non-metallic materials such as PVC or resin, which is not strong enough when used as a fastener. The existing anti-metal RFID tag is based on the RFID electronic tag. A layer of anti-metal material is added, which only solves the problem of failure of the electronic tag when it is attached to the surface of a metal object, but it is impossible to encapsulate the RFID electronic tag inside the metal shell. For example, in the common RFID bolts, the anti-metal RFID tag is attached to the bolt head. Although this type of RFID bolt solves the problem of insufficient strength of the non-metallic RFID electronic tag, the RFID tag is easy to fall off or be damaged by impact during use. Therefore, there is an urgent need for a RFID electronic tag that can encapsulate the RFID electronic tag inside the metal bolt without affecting the normal reading of the RFID electronic tag.

[0021] The material of the metal screw housing 1 is 304 steel, and its size is manufactured in accordance with the relevant national standards for similar standard parts, and can be used interchangeably with ordinary screws of the same category. When the electronic tag does not need to be read, the telescopic column 5 is in a reset state, that is, it is retracted to the inner wall of the bushing 2. When the electronic tag needs to be read, pressing the telescopic column 5 can change the connection position between the hanging rod 4 and the guide groove 7. The telescopic column 5 pops out under the action of the first spring 3. At this time, the RFID electronic tag body 10 is not shielded by the metal screw housing 1 and can be read normally. Press the telescopic column 5 again, and the connection position between the hanging rod 4 and the guide groove 7 returns to the reset state. The first spring 3 is compressed, and the telescopic column 5 is in a reset state again, that is, it is retracted to the inner wall of the bushing 2.
[0022] Further, the guide groove 7 includes a horizontal guide groove 7-1, a reset guide groove 7-2 and an ejection guide groove 7-3, a first pressure head 7-6 is provided at the connection between the reset guide groove 7-2 and one end of the ejection guide groove 7-3, and a second pressure head 7-4 and a reset anchor point 7-5 are provided at the connection between the reset guide groove 7-2 and the other end of the ejection guide groove 7-3;
[0023] Further, the vertex of the first pressing head 7-6 is located below the center line of the horizontal guide groove 7-1, and the vertex of the second pressing head 7-4 is located above the reset anchor point 7-5;
[0024] When the telescopic column 5 is in the reset state, the clamp head 14 of the hanging rod 4 contacts the reset anchor point 1-5, pressing the telescopic column 5. The lower part of the second pressure head 7-4 squeezes the clamp head 14 and presses the clamp head 14 into the pop-up guide groove 7-3. The spring pushes the telescopic column 5 to pop out. The clamp head 14 enters the horizontal guide groove 7-1 along the pop-up guide groove 7-3 and is stuck at the end of the horizontal guide groove 7-1. At this time, the telescopic column 5 is in the pop-up state. When the telescopic column 5 is pressed again, the clamp head 14 slides along the horizontal guide groove 7-1 and contacts the upper part of the first pressure head 7-6 to enter the reset guide groove 7-2, and then returns to the reset anchor point 7-5.
[0025] Furthermore, a card tray 11 is slidably installed in the card slot 13, a second spring 12 is connected between the card tray 11 and the bottom wall of the card slot 13, and the lower part of the package card 9 is fixed to the inner wall of the card tray 11;
[0026] Furthermore, the upper portion of the packaging card 9 is provided with an inclined surface, and one end of the opening 8-1 of the collar 8 is provided with an inclined angle 8-2;
[0027] When the ring 8 is rotated so that the upper end of the card slot is located in the opening of the ring 8, the second spring 12 pushes the card tray 11 to pop the upper part of the packaging card 9 out of the card slot 13. At this time, the packaging card 9 can be taken out with a tool. When the packaging card 9 is inserted again, the ring 8 is rotated so that the bevel 8-2 of the ring 8 squeezes the bevel on the upper part of the packaging card 9 to re-fix the packaging card 9 in the card slot 13.
[0028] By those skilled in the art, the components in this case are connected in sequence. The specific connection and operation sequence should refer to the following working principle. The detailed connection means are well-known technologies in the field. The following mainly introduces the working principle and process.
[0029] Embodiment: When in use, the device can be fixed on relevant equipment or objects in the same way as similar fasteners. When the RFID electronic tag body needs to be read, one end of the telescopic column 5 is pressed, and the connection position of the hanging rod 4 and the guide groove 7 is changed, and the RFID electronic tag body 10 is ejected under the action of the first spring 3. At this time, the RFID electronic tag body 10 is not shielded by the metal screw housing 1 and can be read normally. The telescopic column 5 is pressed again, and the connection position of the hanging rod 4 and the guide groove 7 returns to the reset state, the first spring 3 is compressed, and the telescopic column 5 is in the reset state again, that is, it is contracted to the inner wall of the bushing 2. When the RFID electronic tag body needs to be replaced or destroyed, the ring 8 is rotated so that the upper end of the card slot is located in the opening of the ring 8, and the second spring 12 pushes the card tray 11 to eject the upper part of the package card 9 from the card slot 13. At this time, the package card 9 can be taken out with a tool. When the package card 9 is inserted again, the ring 8 is rotated so that the bevel 8-2 of the ring 8 squeezes the bevel on the upper part of the package card 9 to re-fix the package card 9 in the card slot 13.
