Description

Technical Field

[0001] This utility model relates to the field of electronic tag technology, and in particular to an electronic tag. Background Technology

[0002] Electronic tags are contactless automatic identification devices that use radio frequency technology or other wireless communication methods to store and transmit data. Unlike traditional paper tags that rely on visual reading, they use chips and antennas to achieve wireless data interaction with readers. They are widely used in logistics, retail, security and other scenarios that require efficient information management.

[0003] In existing electronic tags, the tags are glued to the shelf near the goods. Then, a person holds a reader and emits a radio frequency signal of a specific frequency. When the electronic tag enters the signal range, it receives the signal through an antenna and uses electromagnetic induction to obtain energy to activate the chip. The stored information is then sent to the reader through the antenna. The reader receives the data and transmits it to the back-end system for processing.

[0004] However, since the electronic tags bonded with glue are rigidly fixed to the shelves, it may be necessary to forcibly remove and discard the electronic tags in their original positions after the goods are moved, which may lead to a waste of material resources. In addition, the installation and removal of electronic tags are relatively cumbersome, affecting the flexibility and convenience of using electronic tags. Utility Model Content

[0005] The technical problem this utility model aims to solve is that, since the electronic tags bonded with adhesive are rigidly fixed to the shelves, it may be necessary to forcibly remove and discard the electronic tags in their original positions after the goods are moved, which can easily lead to a waste of material resources. Furthermore, the installation and removal of electronic tags is quite cumbersome, affecting the flexibility and ease of use of electronic tags.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an electronic tag, comprising: an electronic tag body, wherein the electronic tag body is internally provided with a chip and an antenna, wherein the antenna receives radio frequency signals and obtains energy through electromagnetic induction to activate the chip, and transmits the stored information to a reader through the antenna; and an adjustment device, wherein the adjustment device is disposed on the electronic tag body, wherein the adjustment device can assist the electronic tag body in quickly fixing on the shelf, and at the same time adjust the fixed height of the electronic tag body.

[0007] Preferably, the adjusting device includes: a rectangular plate, on one side of which a plurality of magnets are fixedly connected, the plurality of magnets being arranged at equal intervals; a plug rod, the surface of which is slidably connected to the inner wall of a hole in the rectangular plate, wherein a spring is fixedly connected between the plug rod and the rectangular plate, wherein one end of the spring is fixedly connected to the rectangular plate and the other end is fixedly connected to the plug rod; a shaft rod, which is slidably mounted on the rectangular plate via a perforated rod, wherein the perforated rod is placed inside the rectangular plate and fixed by the plug rod; and a cylinder, which is fixedly connected to the electronic tag body, wherein the cylinder is sleeved on the surface of the shaft rod, and wherein the cylinder and the shaft rod are fixed by friction.

[0008] The effect achieved by the above components is as follows: By setting an adjustment device, the rectangular plate is first manually moved, causing it to move multiple magnetic blocks. When the rectangular plate moves to a position where it is in contact with the shelf surface, the multiple magnetic blocks attract the metal shelf surface, magnetically fixing the electronic tag body, thus completing the rapid assembly of the electronic tag and the metal shelf. At this time, the insertion rod is manually pulled away from the rectangular plate, and the electronic tag body is manually moved, causing the electronic tag body to move up and down through the cylinder, driving the shaft and the perforated rod. The perforated rod moves up and down along the inside of the rectangular plate. When the electronic tag body moves to the designated position, the inner wall of any hole on the perforated rod coincides with the inner wall of a hole on the rectangular plate. At this time, under the reaction force of the spring, the spring pulls the insertion rod closer to the rectangular plate. The plate is moved to its original position, causing the insertion rod to be moved to the position where it is inserted into the perforated rod, thus fixing the position of the perforated rod and the shaft. This completes the height adjustment of the electronic tag body. At the same time, the electronic tag body is manually rotated, causing the cylinder to rotate around the shaft. The friction and resistance between the shaft surface and the inner wall of the cylinder are used to limit the rotation, so that the electronic tag body is fixed after rotating to a certain angle. This allows for angle adjustment of the electronic tag body, enabling quick assembly with the metal shelf. The installation position, height, and angle of the electronic tag body can be flexibly changed, allowing the electronic tag body to move with the goods. This reduces material waste and cumbersome disassembly and assembly steps when using the electronic tag body, improving the flexibility and convenience of its use.

[0009] Preferably, the surface of the shaft is fixed with a plurality of evenly arranged circular strips, and the inner wall of the cylinder is provided with a plurality of circular grooves, wherein the surface size and shape of the circular strips match the size and shape of the inner wall of the circular grooves.

[0010] The effect achieved by the above components is that by setting the round bar, the round bar can be embedded in the corresponding round groove during the rotation of the cylinder, increasing the friction and resistance between the shaft and the inner wall of the cylinder, and improving the positioning stability of the cylinder and shaft after rotation.

[0011] Preferably, a telescopic rod is fixedly connected to the side of the insertion rod near the spring, wherein the telescopic rod is placed inside the spring, and the other end of the telescopic rod is fixedly connected to the rectangular plate.

[0012] The effect achieved by the above components is as follows: by setting the telescopic rod, the telescopic rod can limit the insertion rod and provide support inside the spring, reducing the possibility of the insertion rod coming out of the rectangular plate hole during the pulling process. At the same time, it can increase the stability of the insertion rod and reduce the shaking of the insertion rod, which would affect the fixing effect on the multi-hole rod.

[0013] Preferably, an auxiliary frame is fixed to one side of the insertion rod, wherein the edge of the auxiliary frame has an angle.

[0014] The effect achieved by the above components is that by setting up the auxiliary frame, a point of force can be provided for personnel to manually pull the insertion rod and the accessible range can be increased, so that personnel can manually move the auxiliary frame to drive the insertion rod to move, thereby improving the convenience and stability of manually pulling the insertion rod.

[0015] Preferably, a rubber block is fixed to the side of the rectangular plate closest to the electronic tag body.

[0016] The effect achieved by the above components is that by setting up rubber blocks, the rubber blocks can separate the rectangular plate from the electronic tag body, reducing the collision and wear between the two and affecting their service life.

[0017] Preferably, a rubber ring is fixed to the side of the rectangular plate near the magnet block, wherein the rubber ring wraps around multiple magnet blocks, and the surface of the rubber ring is slightly higher than the surface of the magnet blocks.

[0018] The effect achieved by the above components is that by setting rubber rings, the rubber rings can separate the rectangular plate from the metal shelf, reducing the wear and tear caused by direct collision between the rectangular plate and the metal shelf, and at the same time reducing the collision noise.

[0019] Preferably, the rectangular plate has two connecting plates symmetrically fixed to its surface, and the connecting plates are provided with multiple holes.

[0020] The effect achieved by the above components is that by setting up the connecting plate, the rectangular plate can be fixedly installed on the metal shelf in another way using the connecting plate and screws, providing multiple installation methods for the rectangular plate and improving the installation flexibility of the rectangular plate.

[0021] The beneficial effects of this utility model are:

[0022] By setting up an adjustment device, the electronic tag body can be quickly assembled with the metal shelf. At the same time, the installation position, height and angle of the electronic tag body can be flexibly changed, so that the electronic tag body can move along with the goods. This reduces the waste of material resources and the cumbersome steps of disassembly and assembly when using the electronic tag body, and improves the flexibility and convenience of using the electronic tag body.

[0032] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0033] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0034] Figure 1-7 An electronic tag is shown, comprising: an electronic tag body 1, wherein the electronic tag body 1 is internally provided with a chip and an antenna, wherein the antenna receives radio frequency signals and obtains energy through electromagnetic induction to activate the chip and transmit the stored information to a reader / writer through the antenna; and an adjustment device 2, wherein the adjustment device 2 is disposed on the electronic tag body 1, wherein the adjustment device 2 can assist the electronic tag body 1 in quickly fixing it on the shelf, and at the same time adjust the fixed height of the electronic tag body 1.

[0035] Figure 2-7The adjustment device 2 shown includes: a rectangular plate 21, with multiple magnet blocks 22 fixedly attached to one side of the rectangular plate 21, the multiple magnet blocks 22 being arranged at equal intervals; a plug rod 28, the surface of the plug rod 28 being slidably connected to the inner wall of the hole on the rectangular plate 21, wherein a spring 211 is fixedly connected between the plug rod 28 and the rectangular plate 21, wherein one end of the spring 211 is fixedly connected to the rectangular plate 21, and the other end is fixedly connected to the plug rod 28; a shaft rod 26, the shaft rod 26 being slidably mounted on the rectangular plate 21 via a perforated rod 25, wherein the perforated rod 25 is placed inside the rectangular plate 21 and fixedly engaged by the plug rod 28; and a cylinder 213, the cylinder 213 being fixedly connected to the electronic tag body 1. The cylinder 213 is fitted onto the surface of the shaft 26, and the cylinder 213 and the shaft 26 are fixed by friction. Using the adjustment device 2, the rectangular plate 21 is first manually moved, causing it to move multiple magnet blocks 22. When the rectangular plate 21 moves to a position where it is in contact with the shelf surface, the multiple magnet blocks 22 attract the metal shelf surface, magnetically fixing the electronic tag body 1, thus completing the rapid assembly of the electronic tag and the metal shelf. At this point, the insertion rod 28 is manually pulled away from the rectangular plate 21, and the electronic tag body 1 is manually moved, causing the electronic tag body... 1. The cylinder 213 drives the shaft 26 and the perforated rod 25 to move up and down, causing the perforated rod 25 to move up and down along the inside of the rectangular plate 21. When the electronic tag body 1 moves to the designated position, the inner wall of any hole on the perforated rod 25 coincides with the inner wall of a hole on the rectangular plate 21. At this time, under the reaction force of the spring 211, the spring 211 pulls the insertion rod 28 to move towards the rectangular plate 21 for reset, so that the insertion rod 28 is reset to the position of being inserted into the perforated rod 25, fixing the position of the perforated rod 25 and the shaft 26, thereby completing the height adjustment of the electronic tag body 1. At the same time, the electronic tag body can be manually rotated. 1. The cylinder 213 is driven to rotate around the shaft 26. The friction and resistance between the surface of the shaft 26 and the inner wall of the cylinder 213 are used to limit the rotation, so that the electronic tag body 1 is fixed after rotating to a certain angle. This allows the angle of the electronic tag body 1 to be adjusted, enabling the electronic tag body 1 to be quickly assembled with the metal shelf. At the same time, the installation position, height and angle of the electronic tag body 1 can be flexibly changed, so that the electronic tag body 1 can move along with the goods. This reduces the waste of material resources and the cumbersome steps of disassembly and assembly when using the electronic tag body 1, and improves the flexibility and convenience of using the electronic tag body 1.

[0036] Figure 2-7The shaft 26 shown has multiple evenly arranged circular strips 27 fixed to its surface. The inner wall of the cylinder 213 has multiple circular grooves, with the surface size and shape of the circular strips 27 matching the size and shape of the inner wall of the grooves. By setting the circular strips 27, they can be embedded into the corresponding circular grooves during the rotation of the cylinder 213, increasing the friction and resistance between the shaft 26 and the inner wall of the cylinder 213, and improving the positioning stability of the cylinder 213 and shaft 26 after rotation. The insertion rod 28 is close to the spring 21. A telescopic rod 212 is fixedly connected to one side of the plate 21. The telescopic rod 212 is placed inside the spring 211, and the other end of the telescopic rod 212 is fixedly connected to the rectangular plate 21. By setting the telescopic rod 212, the telescopic rod 212 can limit the insertion rod 28 and provide support inside the spring 211, reducing the possibility of the insertion rod 28 coming out of the hole in the rectangular plate 21 during the pulling process. At the same time, it can increase the stability of the insertion rod 28 and reduce the shaking of the insertion rod 28, which would affect the fixing effect of the multi-hole rod 25.

[0037] Figure 2-7 An auxiliary frame 29 is fixed to one side of the inserted rod 28. The edge of the auxiliary frame 29 has an angle. By setting the auxiliary frame 29, a force point can be provided for personnel to manually pull the inserted rod 28 and the accessible range can be increased. This allows personnel to manually move the auxiliary frame 29 to move the inserted rod 28, improving the convenience and stability of manually pulling the inserted rod 28. A rubber block 210 is fixed to the side of the rectangular plate 21 near the electronic tag body 1. By setting the rubber block 210, the rubber block 210 can separate the rectangular plate 21 from the electronic tag body 1, reducing the collision and wear between the two and affecting the service life.

[0038] Figure 2-7 A rubber ring 23 is fixed to the side of the rectangular plate 21 near the magnet block 22. The rubber ring 23 wraps around multiple magnet blocks 22, and the surface of the rubber ring 23 is slightly higher than the surface of the magnet block 22. By setting the rubber ring 23, the rubber ring 23 can separate the rectangular plate 21 from the metal shelf, reducing the possibility of large wear caused by direct collision between the rectangular plate 21 and the metal shelf, and also reducing some of the collision noise. Two connecting plates 24 are symmetrically fixed to the surface of the rectangular plate 21. The connecting plates 24 have multiple holes. By setting the connecting plates 24, the rectangular plate 21 can be fixed to the metal shelf in another way using the connecting plates 24 and screws, providing multiple installation methods for the rectangular plate 21 and improving the installation flexibility of the rectangular plate 21.

[0039] Working principle: First, manually move the rectangular plate 21, causing it to move multiple magnet blocks 22. When the rectangular plate 21 moves to a position where it is in contact with the shelf surface, the magnet blocks 22 attract the metal shelf surface, magnetically fixing the electronic tag body 1, thus completing the rapid assembly of the electronic tag with the metal shelf. Then, manually pull the insertion rod 28 away from the rectangular plate 21 and manually move the electronic tag body 1, causing it to move up and down through the cylinder 213, driving the shaft 26 and the perforated rod 25. This causes the perforated rod 25 to move up and down along the interior of the rectangular plate 21. When the electronic tag body 1 reaches the designated position, the perforated rod 25... When the inner wall of any hole on rod 25 coincides with the inner wall of a hole on rectangular plate 21, the reaction force of spring 211 causes spring 211 to pull the insertion rod 28 toward the rectangular plate 21 for reset movement. This resets the insertion rod 28 to the position where it is inserted into the multi-hole rod 25, fixing the positions of the multi-hole rod 25 and the shaft 26, thus completing the height adjustment of the electronic tag body 1. At the same time, manually rotating the electronic tag body 1 drives the cylinder 213 to rotate around the shaft 26. The friction and resistance between the surface of the shaft 26 and the inner wall of the cylinder 213 are used for limiting the rotation, so that the electronic tag body 1 is fixed after rotating to a certain angle, thereby realizing the angle adjustment of the electronic tag body 1.

[0040] At this time, the person holding the reader emits a radio frequency signal of a specific frequency. After the electronic tag body 1 enters the signal range, it receives the signal through the antenna, obtains energy through electromagnetic induction to activate the chip, and sends the stored information to the reader through the antenna. The reader receives the data and transmits it to the background system for processing.

[0041] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
