[0017] 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.

[0018] Please see Figure 1 , Figure 2 , Figure 3 and Figure 4 The illustration shows an electronic price tag that is easy to replace quickly. It includes a protective structure 1 for attaching the electronic price tag and a support structure 2 for opening the protective structure 1. The support structure 2 includes an L-shaped rod 201, an L-shaped tube 202, and a base box 203. The two L-shaped rods 201 and the two L-shaped tubes 202 are symmetrically distributed. The horizontal end of the L-shaped rod 201 is inserted into the horizontal end of the L-shaped tube 202 and slidably connected. The L-shaped rod 201 and the L-shaped tube 202 are assembled to form an inverted U shape. The two base boxes 203 are arranged in parallel and their tops are open. The vertical ends of the L-shaped rods 201 and the L-shaped tubes 202 are inserted into the base boxes 203 and are rotatably connected to the inside of the base boxes 203 through a rotating shaft 209. One of the two adjacent rotating shafts 209 is fixedly fitted with a first gear 206, and the other is fixedly fitted with a second gear 207. The first gear 206 and the second gear 207 mesh with each other. The bottom of the base box 203 is equipped with an installation structure 3 that is fixed to the side of the refrigerator.

[0019] It is worth noting that the two bottom boxes 203 are fixed to both sides of the fresh food cabinet by the installation structure 3, while the hook rod 103 in the protective structure 1 is suspended from the horizontal end of the L-shaped rod 201 and the L-shaped tube 202. When in use, the electronic price tag is placed in the closed space of the first snap box 101 and the second snap box 102. When a certain number of electronic price tags need to be replaced, or when they malfunction or run out of power, they can be manually operated by using the cooperation of the L-shaped rod 201 and the L-shaped tube 202, as well as the first gear 206 and the second... The meshing of gear 207 causes the L-shaped rod 201 and L-shaped tube 202 to rotate outward and separate. At the same time, the first snap box 101 and the second snap box 102 will open by rotating the pin 105, making it easy to take out the electronic price tags that need to be replaced one by one. After the replacement is completed, the L-shaped rod 201 and L-shaped tube 202 are brought together again, and the first snap box 101 and the second snap box 102 are closed. In this way, all the protective structures 1 with electronic price tags are in an open state, eliminating the need for manual opening and replacement one by one, saving operation time and improving convenience.

[0020] See Figure 3 and Figure 4The bottom box 203 has two fixedly connected limiting rubber blocks 204 on both sides of the top position. The adjacent sides of the two limiting rubber blocks 204 are provided with arc grooves 205. When the L-shaped rod 201 and L-shaped tube 202 are unfolded to a certain angle, they will press into the arc grooves 205 on the limiting rubber blocks 204 to ensure that the L-shaped rod 201 and L-shaped tube 202 remain stable after being opened to a certain angle, and prevent interference with the replacement operation of electronic price tags due to reclosing.

[0021] Please see Figure 1 and Figure 2 Several protective structures 1 are fixedly connected to the horizontal ends of the L-shaped rod 201 and the L-shaped tube 202. The protective structure 1 includes a first buckle box 101 and a second buckle box 102. The first buckle box 101 and the second buckle box 102 are symmetrically arranged. The second buckle box 102 is sleeved inside the first buckle box 101. The bottoms of the first buckle box 101 and the second buckle box 102 are rotatably connected by a pin 105. The top sidewalls of the first buckle box 101 and the second buckle box 102 are both fixedly connected to hook rods 103. The inner arc-shaped sidewall of the hook rod 103 is fixedly connected to an arc-shaped retaining ring 104.

[0022] It is worth noting that the electronic price tags are placed inside the first snap box 101 and the second snap box 102 for hanging use, which makes it convenient for people to intuitively view the prices of products inside the fresh food cabinet, enhances the display and promotion effect of the mall, and is easily installed by relying on the arc-shaped buckle 104 on the hook rod 103 and the L-shaped rod 201 or L-shaped tube 202, which is simple to operate and further improves the convenience of operation.

[0023] Please refer to Figure 2 The hook rods 103 on the first buckle box 101 and the hook rods 103 on the second buckle box 102 are symmetrically distributed in a staggered manner. The first buckle box 101 and the second buckle box 102 are made of transparent plastic material. The transparent material can display the internal electronic price tag to provide price information and other related product information.

[0024] See Figure 1 , Figure 3 and Figure 4 The mounting structure 3 includes a lead screw 302 and a slide rail 304. The top of the slide rail 304 is fixedly connected to the bottom box 203, and the bottom is slidably connected to two parallel clamping plates 303. The lead screw 302 is horizontally arranged inside the slide rail 304. The two ends of the lead screw 302 rotate and move with the two sides of the slide rail 304. One end of the lead screw 302 passes through one side of the slide rail 304, and the through end is fixedly connected to a knob 301. The clamping plates 303 have threaded holes that match the lead screw 302 inside, and the two threaded holes have opposite thread directions.

[0025] It is worth noting that fresh food display cases are typically designed to be open, with the L-shaped rod 201 inserted into the horizontal end of the L-shaped tube 202 and flexibly installed via a sliding connection to accommodate display cases of different lengths, thus expanding the range of applications and enhancing its practicality. During installation, rotating the knob 301 drives the lead screw 302 to rotate. Since the threads of the two threaded holes are in opposite directions, the two clamping plates 303 can move horizontally in opposite directions, thereby changing the distance between the two clamping plates 303 and allowing the clamping plates 303 to be firmly fixed to the side wall of the fresh food display case. The lead screw 302 has a self-locking function, ensuring the stability of the device during use.

[0026] See Figure 4 The rotating area of ​​the pivot 209 and the base box 203 is fixedly fitted with a damping ring 208. When the L-shaped rod 201 and the L-shaped tube 202 are unfolded to a certain angle, they will press into the arc groove 205 on the limiting rubber block 204 to ensure that the L-shaped rod 201 and the L-shaped tube 202 remain stable after opening to a certain angle, and prevent interference with the replacement operation of the electronic price tag due to reclosing.

[0027] Working principle: The two bottom boxes 203 are fixed to both sides of the fresh food cabinet by the installation structure 3. At the same time, the hook rod 103 in the protective structure 1 is suspended from the horizontal end of the L-shaped rod 201 and L-shaped tube 202. When in use, the electronic price tag is placed in the closed space of the first snap box 101 and the second snap box 102. When a certain number of electronic price tags need to be replaced, or when they malfunction or run out of power, they can be manually operated. By using the cooperation of the L-shaped rod 201 and L-shaped tube 202, as well as the meshing of the first gear 206 and the second gear 207, the L-shaped rod 201 and L-shaped tube 202 are rotated outward and separated. At the same time, the first snap box 101 and the second snap box 102 will open by rotating the pin 105, making it easy to take out the electronic price tag that needs to be replaced in sequence. After the replacement is completed, the L-shaped rod 201 and L-shaped tube 202 are brought together again, and the first snap box 101 and the second snap box 102 are closed.
