Abstract
Description
Technical Field
[0001] This utility model relates to the field of electronic tag technology, and in particular to a detachable electronic tag that is easy to fix. Background Technology
[0002] Electronic tags, also known as RFID (Radio Frequency Identification) tags, are a non-contact automatic identification technology that uses radio waves to automatically identify specific targets and obtain relevant data without human intervention or direct contact. An RFID system typically consists of three main parts: a tag, a reader, and an antenna.
[0003] Electronic Shelf Labels (ESLs) on supermarket shelves are electronic devices used to display product prices and other information. They are typically connected to a central computer system via a wireless network and can be remotely updated with information including prices, promotional information, and inventory status.
[0004] Electronic tags on supermarket shelves are usually installed using clips. The tags are designed to be inserted into special plastic or metal clips and fixed to the edge of the shelf. This method makes it easy to replace and adjust the position of the tags.
[0005] However, clip-on fastening is not aesthetically pleasing, and after being fixed, the electronic tag will be higher than the edge of the shelf, making it easy for customers to bump into it and fall off when retrieving goods. Utility Model Content
[0006] To address the problems of existing technologies, this utility model provides a detachable electronic tag that is easy to fix, comprising:
[0007] The electronic tag itself;
[0008] The mounting housing is connected to the back of the electronic tag body. The mounting housing is hollow inside, and sliding holes are provided at the top and bottom of the mounting housing. Through holes are provided on the opposite side walls of the mounting housing.
[0009] Two sliders are slidably connected within the sliding holes, respectively.
[0010] Two compression blocks are located inside the mounting housing;
[0011] Two connecting rods are slidably connected in the through hole, and their ends are respectively connected to the extrusion block;
[0012] Each connecting rod is connected to an elastic component. When the elastic component is not under force, it pulls the squeezing block to move, thereby pushing the slider to slide outward of the mounting housing and installing the electronic tag body into the U-shaped groove of the supermarket shelf.
[0013] Furthermore, the slider has a U-shaped structure, and the two side plates of the slider are located inside the mounting housing;
[0014] The extrusion block has a trapezoidal structure, and the connecting rod is connected to the small end of the extrusion block;
[0015] The two inclined sides of each extrusion block are slidably connected to the side plates corresponding to the two sliders.
[0016] Furthermore, the two side plates of the slider have an overall arc shape in their facing sidewalls and ends.
[0017] Furthermore, the connecting rod is connected to the small end of the extrusion block, and the two inclined sides of the extrusion block are also arc-shaped.
[0018] Furthermore, each of the sidewalls where the slider contacts the inner wall of the mounting housing is connected to a first sliding rod, and a first sliding groove is provided at the corresponding position on the inner wall of the mounting housing, with the first sliding rod slidably connected in the first sliding groove.
[0019] Furthermore, a second sliding rod is connected to the side wall of the extrusion block, and a second sliding groove is opened at a corresponding position on the inner wall of the mounting housing, and the second sliding rod is slidably connected in the second sliding groove.
[0020] Furthermore, a limiting block is connected to the end of the connecting rod located outside the mounting housing, and the elastic component is located between the limiting block and the mounting housing.
[0021] Furthermore, the elastic component is a spring, which is sleeved on the connecting rod.
[0022] The beneficial effects of the technical solution provided by this utility model are as follows: In this utility model, a mounting housing is connected to the back of the electronic tag body. Sliders are slidably connected to the top and bottom of the mounting housing. Connecting rods are slidably connected to the opposite side walls of the mounting housing. A pressing block is provided inside the mounting housing. Elastic components are connected to the connecting rods. When the elastic components are not under force, they pull the pressing block to move, thereby pushing the slider to slide outward of the mounting housing and installing the electronic tag body into the U-shaped groove of the supermarket shelf. This allows the electronic tag to be detachably connected to the supermarket shelf, and the electronic tag will not be higher than the edge of the shelf, so that it will not cause interference when customers take goods, and it is not easy to fall off.

[0035] See Figures 1-7 A detachable electronic tag that is easy to fix includes an electronic tag body 1 and a mounting housing 2. The electronic tag body 1 is an existing electronic tag on supermarket shelves, which is a digital device used to display product prices and other information. It is usually composed of the following main components: 1. Display screen: used to display product prices, names, promotional information, etc., usually using electronic ink (E-Ink) or LCD screens; 2. Communication module: responsible for exchanging data with the back-end server and receiving update information. Common communication methods include wireless technologies such as RFID, Bluetooth, Wi-Fi, and Zigbee; 3. Control unit: responsible for processing the received data and controlling the display screen to display the corresponding information, usually a microcontroller or microprocessor; 4. Power management module: since electronic tags may need to work for a long time, effective power management is crucial for extending battery life or reducing power consumption; 5. Housing: protects the internal electronic components from physical damage.
[0036] The dimensions of the mounting housing 2 are the same as the outer shell dimensions of the electronic tag body 1. The mounting housing 2 is fixedly connected to the back of the outer shell of the electronic tag body 1. The interior of the mounting housing 2 is hollow, and sliding holes are provided at the top and bottom of the mounting housing 2. The sliding holes are elongated sliding holes, and sliders 3 are connected inside the sliding holes. The length and thickness of the sliders 3 match the dimensions of the sliding holes. Through holes are provided on the opposite side walls of the mounting housing 2. Connecting rods 5 are slidably connected inside the through holes. The through holes are circular through holes, and the connecting rods 5 are cylindrical rods that match the diameter of the through holes. Elastic components are connected to the connecting rods 5. Two extrusion blocks 4 are slidably connected inside the mounting housing 2. The ends of the two connecting rods 5 located inside the mounting housing 2 are respectively connected to the two extrusion blocks 4.
[0037] Figure 3 For a schematic diagram of the connection between the easily fixed detachable electronic tag and the U-shaped groove of the supermarket shelf, please refer to [reference needed]. Figure 3In use, press the connecting rod 5 into the mounting housing 2, compress the elastic component, and push the two extrusion blocks 4 to move. The two sliders 3 slide into the mounting housing 2. Then, place the electronic tag into the U-shaped groove on the front side of the supermarket shelf. Release the connecting rod 5, and the elastic component extends, pulling the connecting rod 5 to move outward. This pulls the two extrusion blocks 4 to squeeze the two sliders 3 to slide outward from the mounting housing 2. The two sliders 3 abut against the top and bottom of the U-shaped groove of the supermarket shelf, respectively, thus detachably connecting the electronic tag to the supermarket shelf. The electronic tag will not be higher than the edge of the shelf, so it will not interfere with customers when they take goods, and it is not easy for it to fall off.
[0038] Furthermore, the slider 3 has a U-shaped structure, with its two side plates 7 facing inwards towards the mounting housing 2. The extrusion block 4 has a trapezoidal structure, with the connecting rod 5 connected to the small end of the extrusion block 4. The upper and lower inclined edges of the two extrusion blocks 4 respectively contact the ends of the two side plates 7 of the two sliders 3. When the connecting rod 5 is pressed, the extrusion block 4 is pushed inwards, causing the inclined edge of the extrusion block 4 to be located in the groove of the slider 3. When the connecting rod 5 is released, the elastic component pulls the extrusion block 4 to slide to both sides. Since the large end of the extrusion block 4 faces inwards, during the sliding process of the extrusion block 4, the inclined edge contacts the end of the side plate 7 of the slider 3 and pushes the slider 3 to slide outwards towards the mounting housing 2.
[0039] Additionally, it should be noted that after pressing the connecting rod 5 to push the extrusion block 4 inward, the upper slider 3 will automatically slide into the mounting housing 2 due to gravity, while the lower slider 3 will remain outside the mounting housing 2. Therefore, when installing into the U-shaped groove of the shelf, first use the bottom of the U-shaped groove to hold the lower slider 3 in place, so that the lower slider 3 is inside the mounting housing 2. Then slide it into the U-shaped groove of the shelf. After it has fully slid in, release the connecting rod 5 to expel the two sliders 3 from the mounting housing 2 and lock them into the U-shaped groove of the shelf. When it is necessary to remove them, press the connecting rod 5, and the upper slider 3 will automatically slide into the mounting housing 2. The lower slider 3 will also loosen. The operator can then gently press it down and slide it out of the U-shaped groove of the shelf.
[0040] Furthermore, the two side plates 7 of the slider 3 are generally arc-shaped with their side walls and ends facing each other. The connecting rod 5 is connected to the small end of the extrusion block 4, and the two sides of the extrusion block 4 are also arc-shaped, which makes the extrusion block 4 push the slider 3 more smoothly.
[0041] Furthermore, a first sliding rod 8 is connected to the side wall of the slider 3 that contacts the inner wall of the mounting housing 2. A first sliding groove 9 is provided at the corresponding position of the inner wall of the mounting housing 2 along the moving direction of the slider 3. The first sliding rod 8 is slidably connected in the first sliding groove 9, which can limit the movement stroke of the slider 3 and make the slider 3 more stable when sliding up and down.
[0042] Furthermore, a second slide rod 10 is connected to the side wall of the extrusion block 4, and a second slide groove is opened at the corresponding position on the inner wall of the mounting housing 2 along the movement direction of the extrusion block 4. The second slide rod 10 is slidably connected in the second slide groove, thereby making the extrusion block 4 more stable when sliding.
[0043] Furthermore, the end of the connecting rod 5 located outside the mounting housing 2 is connected to a limiting block 11, and the elastic component is a spring 12, which is sleeved on the connecting rod 5, and the spring 12 is located between the limiting block 11 and the mounting housing 2.
[0044] When the connecting rod 5 is pressed, the spring 12 is compressed. When the connecting rod 5 is released, the spring 12 returns to its initial state, pushing the limit block 11 to pull the connecting rod 5 to move.
[0045] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
