Description

Technical Field

[0001] This application relates to the field of label guide technology, and more specifically, to a multifunctional label guide that is compatible with electronic price tags and promotional paper. Background Technology

[0002] Electronic shelf labels are widely used in retail settings such as shopping malls and supermarkets. However, due to limitations in screen color performance and display detail, they still need to be paired with promotional paper to supplement information display during daily promotional activities.

[0003] While existing technologies have developed label rails that support the combined display of electronic price tags and promotional flyers, the promotional flyer mounting structure of these rails generally suffers from design flaws. Because promotional flyers need frequent replacement, the repeated insertion and removal operations cause friction and wear on the clamping components (such as clips) at the mounting points, leading to gradual aging, deformation, and even breakage. After a period of use, the aging mounting structure can no longer provide stable clamping force, resulting in loosening and displacement of the promotional flyers. This not only affects the display of promotional information but may also cause the flyers to fall off and interfere with normal shelf display, causing inconvenience to daily operations in retail settings. Summary of the Invention

The bottom end of the shelf adapter structure is provided with a shelf snap-fit ​​elastic hook that bends toward the main mounting plate. An angle piece hook is provided in the middle of the shelf adapter structure on the side facing the main mounting plate. A shelf adapter expansion groove is provided in the middle of the side of the shelf adapter structure away from the main mounting plate.

[0006] Preferably, a connecting soft material is provided between the angle piece and the rear transparent piece, the connecting soft material enables the angle piece to change angle, and the angle piece and the angle piece hook are detachably connected.

[0007] Preferably, the elastic element between the U-shaped snap-fit ​​strip and the two positioning blocks at its two ends includes a pin, with an outer fixing plate and an inner fixing plate slidably sleeved at both ends of the pin, the outer fixing plate being inserted into the positioning block, the inner fixing plate being inserted into the U-shaped snap-fit ​​strip, and a spring being fixedly connected between the outer fixing plate and the inner fixing plate.

[0008] Preferably, the pin is slidably inserted into the positioning block and passes through the positioning block.

[0009] Preferably, the inner fixing piece can slide axially on the pin, and the outer fixing piece has the ability to slide and rotate on the pin.

[0019] The technical solutions in the embodiments of this application will now be described with reference to the accompanying drawings.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, not all of them. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0021] Example 1, as Figures 1-10 , Figures 16-21 As shown, a multifunctional label guide rail for adapting to electronic shelf labels and promotional paper according to an embodiment of this application includes a main body 1. The main body 1 includes a main mounting plate 11. A rear transparent sheet 12 and a shelf adaptation structure 13 are arranged sequentially from the inside to the outside on the back of the main mounting plate 11. An angle piece 14 adapted to the shelf adaptation structure 13 is provided on the rear transparent sheet 12. An upper slot rib 111 and a lower slot rib 112 adapted to each other are provided on the front of the main mounting plate 11. A friction soft material 113 is provided on the outer side of the upper slot rib 111. An electronic shelf label lower hook 114 is provided on the outer side of the lower slot rib 112. An electronic shelf label upper hook 115 adapted to the electronic shelf label lower hook 114 is provided on the outer side of the top of the main mounting plate 11.

[0022] It is understood that, in specific embodiments of this application, a rear promotional paper can be snapped between the rear transparent sheet 12 and the main mounting plate 11, and an electronic price tag can be installed between the lower hook 114 and the upper hook 115 of the electronic price tag.

[0023] Specifically, a guide rail connecting material 131 is provided between the shelf adapter structure 13 and the main mounting plate 11. The guide rail connecting material 131 enables the shelf adapter structure 13 to have angle change capability. The bottom end of the shelf adapter structure 13 is provided with a shelf snap-fit ​​elastic hook 132 that bends toward the main mounting plate 11. An angle piece hook 133 is provided in the middle of the side of the shelf adapter structure 13 facing the main mounting plate 11. A shelf adapter expansion groove 134 is provided in the middle of the side of the shelf adapter structure 13 away from the main mounting plate 11.

[0024] An angle piece connecting soft material 141 is provided between the angle piece 14 and the rear transparent piece 12. The angle piece connecting soft material 141 enables the angle piece 14 to have the ability to change angles. The angle piece 14 and the angle piece hook 133 can be detachably connected.

[0025] It should be noted that in the specific embodiments of this application, the length of the angle piece 14 is preset to different specifications, and different lengths can be selected according to the actual display needs in order to determine the tilt angle of the guide rail.

[0026] like Figure 21 As shown, in actual use, the shelf clip elastic hook 132 is directly inserted into the corresponding shelf clip slot to complete the basic fixation; the shelf adapter expansion slot 134 can be used to insert accessories such as baffles and dividers as needed to realize flexible division of shelf space.

[0027] It should be further noted that, in the specific embodiments of this application, a promotional paper card connector 2 is provided on the bottom side of the lower slot rib 112 and the lower clip hook 114 of the electronic price tag. The promotional paper card connector 2 includes a U-shaped connector strip 21 provided on the bottom side of the lower slot rib 112 and the lower clip hook 114 of the electronic price tag. A front transparent sheet 22 is detachably connected to the U-shaped connector strip 21, and two sets of extension pieces 23 are symmetrically rotatably connected to the outer side of the front transparent sheet 22. Two extension pieces 23 are symmetrically provided at both ends of the U-shaped connector strip 21. Two positioning blocks 211 are fixed to the bottom sides of the lower slot rib 112 and the lower clip hook 114 of the electronic price tag, respectively. An elastic element is provided between the U-shaped clip strip 21 and the two positioning blocks 211 at both ends. One end of the elastic element is inserted into the positioning block 211, and the other end of the elastic element is inserted into the U-shaped clip strip 21. The U-shaped clip strip 21 is connected to the two positioning blocks 211 through the elastic element. The U-shaped clip strip 21 has the functions of rotation and reset with the elastic element as the axis.

[0028] Among them, at least two cylindrical protrusions are fixedly connected to the side of the extension piece 23 facing the front transparent piece 22. The two cylindrical protrusions are inserted into the front transparent piece 22. It can be understood that this design allows the extension piece 23 to be fixedly inserted into the side of the front transparent piece 22 when not in use, preventing the extension piece 23 from hanging down and swaying under the front transparent piece 22.

[0029] It should be noted that a positioning groove 223 is provided on the bottom side of the front transparent sheet 22, and the extension sheet 23 is rotatably connected to the positioning groove 223. The positioning groove 223 is limited to the side facing the main mounting plate 11, so that the extension sheet 23 can only be rotated to an angle that is on the same plane as the front transparent sheet 22.

[0030] It should be further explained that a fixed magnetic block 232 is slidably connected to the side of the extension piece 23 away from the front transparent piece 22, and a movable magnetic block 234 is magnetically attracted to the side of the fixed magnetic block 232 away from the extension piece 23. Specifically, the extension piece 23 is provided with a groove 231 along its length, and a slider 233 is fixedly connected to one side of the fixed magnetic block 232. The slider 233 is limited to sliding in the groove 231. It can be understood that with this design, when installing a larger promotional paper (the bottom end of the promotional paper extends beyond the bottom end of the front transparent piece 22), the extension piece 23 can be removed from the front transparent piece 22, and the extension piece 23 can be rotated to the bottom side of the front transparent piece 22. At this time, the fixed magnetic block 232 and the movable magnetic block 234 sliding on it can be used to clamp the promotional paper from both sides. In this way, the bottom end of the promotional paper can be fixed, and the clamping range of the front transparent piece 22 on the front promotional paper can be increased.

[0031] The elastic element between the U-shaped snap-fit ​​strip 21 and the two positioning blocks 211 at both ends includes a pin 212. The two ends of the pin 212 are respectively slidably fitted with an outer fixing piece 213 and an inner fixing piece 215. The outer fixing piece 213 is inserted into the positioning block 211, and the inner fixing piece 215 is inserted into the U-shaped snap-fit ​​strip 21. A spring 217 is fixed between the outer fixing piece 213 and the inner fixing piece 215.

[0032] The pin 212 is slidably inserted into the positioning block 211 and passes through the positioning block 211.

[0033] It should be noted that the inner fixing plate 215 can only slide axially on the pin 212, while the outer fixing plate 213 has the ability to slide and rotate on the pin 212.

[0034] Furthermore, a positioning shaft 214 is non-coaxially fixed to one side of the outer fixing plate 213, and the positioning shaft 214 is slidably inserted into the positioning block 211. A positioning shaft 216 is non-coaxially fixed to one side of the inner fixing plate 215, and the positioning shaft 216 is slidably inserted into the U-shaped snap-fit ​​strip 21.

[0035] It should be noted that a fixing bolt 221 is slidably inserted into the front transparent sheet 22. The fixing bolt 221 passes through the outside of the U-shaped snap-fit ​​strip 21 and is inserted into the front transparent sheet 22, and then passes through the inside of the front transparent sheet 22. The fixing bolt 221 passes through the center of the U-shaped snap-fit ​​strip 21.

[0036] Therefore, it can be understood that when the U-shaped snap-fit ​​strip 21 rotates around the pin 212, it will drive the inner fixing piece 215 to rotate synchronously in the same direction. Since the inner fixing piece 215 and the pin 212 only have an axial sliding relationship, the pin 212 will also rotate synchronously at this time. The outer fixing piece 213 is fixed to the positioning block 211 through the positioning shaft 214 on it. Therefore, the spring 217 will be subjected to a torsional action. Through this torsion, the U-shaped snap-fit ​​strip 21 has an elastic restoring effect. It can also be understood that when installing the front promotional paper, it is only necessary to rotate the front transparent piece 22 outward. Create an open gap between the front transparent sheet 22 and the main mounting plate 11, insert the front promotional paper, and then release the front transparent sheet 22. Under the reset effect of the spring 217, the front transparent sheet 22 will clamp and fix the front promotional paper. When the bottom edge of the front promotional paper extends beyond the front transparent sheet 22, the extension piece 23 fixed to the side of the front transparent sheet 22 can be removed and rotated to the same angle as the front transparent sheet 22. Then, slide the fixed magnetic block 232 to move it to a position that matches the bottom edge of the front promotional paper, remove the movable magnetic block 234 on it, and open the other side of the front promotional paper. The front promotional paper is attached to the fixed magnetic block 232, thus securing the bottom edge of the paper. However, if the transparency of the front transparent sheet 22 decreases due to wear during long-term use, it can be replaced by removing the fixing bolt 221. Similarly, if the elastic clamping effect of the front transparent sheet 22 decreases, the spring 217 on that side can be compressed by axially displacing the U-shaped clip 21 to one side. This causes the pin 212 on that side to extend into a corresponding positioning block 211, allowing the pin 212 on the other side to be pulled out from the corresponding positioning block 211. Remove the pin 212 on this side, along with the outer fixing piece 213, the inner fixing piece 215, and the spring 217. Then, reverse the movement of the U-shaped clip 21 to remove it from the other positioning block 211. Replace the outer fixing piece 213, the inner fixing piece 215, and the spring 217 that are fixed together. Then, reinstall the U-shaped clip 21 according to the above disassembly steps. This design allows the front transparent sheet 22 to be used with different sizes of front promotional paper, and ensures its clamping force on the front promotional paper and its transparency, thus ensuring the fixation and display effect of the front promotional paper.

[0037] In related technologies, a multi-functional label guide rail adapted to electronic shelf labels and promotional paper is proposed. This guide rail has the dual function of displaying promotional paper and installing electronic shelf labels. However, electronic shelf labels are updated and iterated at a rapid pace, and different models and specifications of electronic shelf labels differ in size, installation interface, etc. In existing designs, if the lower clip 114 and upper clip 115 used to fix the electronic shelf labels adopt a non-adjustable fixing structure, the guide rail will not be able to adapt to different specifications of electronic shelf labels. This will not only affect the stability and clarity of information display due to installation misalignment, but also require supermarkets to frequently replace the entire guide rail to adapt to new shelf labels, significantly increasing equipment replacement costs and operational burden.

[0038] Example 2, according to some embodiments of this application, such as Figure 11 and Figure 12 As shown, an adjustment assembly 3 is provided on the top of the main mounting plate 11. The adjustment assembly 3 includes a tensioning member 31 provided on the top of the electronic price tag hook 115 and a lifting plate 32 provided on the top of the main mounting plate 11. The tensioning member 31 is used to adjust the elasticity between the electronic price tag hook 115 and the main mounting plate 11, and the lifting plate 32 is used to adjust the distance between the electronic price tag hook 115 and the electronic price tag lower hook 114.

[0039] Specifically, the tensioning component 31 includes a vertical baffle 311 fixed to the top of the hook 115 on the electronic price tag. An adjusting bolt 312 slides through the center of the vertical baffle 311. Two guide rods 313 slide through the sides of the vertical baffle 311. A spring 314 is positioned and sleeved at the outward end of the guide rods 313 and the adjusting bolt 312.

[0040] It should be noted that the second spring 314 does not have a displacement effect at the ends of the first guide rod 313 and the first adjusting bolt 312.

[0041] Specifically, adjusting bolt 312 is threadedly connected to lifting plate 32, and guide rod 313 is fixedly connected to lifting plate 32.

[0042] Furthermore, the lifting plate 32 is threaded with an adjusting bolt 321, which passes through the adjusting bolt 321 and is rotatably connected to the main mounting plate 11. A guide rod 322 slides through the lifting plate 32 and is fixed to the main mounting plate 11.

[0043] Therefore, in practical use, the distance between the end of adjusting bolt 312 furthest from the lifting plate 32 and the lifting plate 32 can be changed by rotating adjusting bolt 312. This changes the degree of compression on the guide rod 313 and the spring 314 fitted on adjusting bolt 312. When the end of adjusting bolt 312 furthest from the lifting plate 32 moves away from the lifting plate 32, the vertical baffle 311 and the hook 115 on the electronic price tag can have a longer displacement stroke relative to the lifting plate 32. Conversely, the displacement stroke of the vertical baffle 311 and the hook 115 on the electronic price tag relative to the lifting plate 32 is shortened. The displacement stroke of spring 2 can be varied to accommodate electronic price tags with different clamping thicknesses. At the same time, the design of spring 2 314 enables the hook 115 on the electronic price tag to have elastic displacement, that is, it can form elastic compression when clamping the electronic price tag. The rotation of adjusting bolt 1 312 can also change the force of elastic compression, ensuring the stability of the electronic price tag installation while avoiding damage to the electronic price tag due to rigid force. In this embodiment of the application, it should be noted that the lower hook 114 of the electronic price tag can adopt a fixed structure design, which only serves to lift the bottom of the electronic price tag. In this embodiment of the application, when the height of the electronic price tag changes, the height of the lifting plate 32 relative to the main mounting plate 11 can be changed by rotating the adjusting bolt 321, so that the height of the hook 115 on the electronic price tag changes synchronously to adapt to the snapping effect of electronic price tags of different heights.

[0044] In related technologies, a multi-functional label guide rail adapted to electronic shelf labels and promotional paper uses the aforementioned elastic clamping structure for the electronic shelf labels. During the disassembly of a single electronic shelf label, the hooks 115 on the fixed electronic shelf label will be displaced outward due to the force. This displacement will directly cause the tension of the entire guide rail's elastic clamping system to become unbalanced. The clamping force on all installed electronic shelf labels will decrease simultaneously, which will easily cause other electronic shelf labels to loosen and fall off due to unstable fixing, seriously affecting the safety of use and the stability of display.

[0045] Example 3, according to some embodiments of this application, such as Figures 13-15 As shown, multiple independent snap-fit ​​components 4 are slidably connected within the upper slot rib 111 and the lower slot rib 112. Two independent snap-fit ​​components 4 form a group. Each independent snap-fit ​​component 4 includes a snap strip 41 that slides between the upper slot rib 111 and the lower slot rib 112. An extension compartment 42 is fixedly connected to the outward side of the snap strip 41. A snap-fit ​​plate 43 is elastically inserted into the extension compartment 42. The extension compartment 42 extends outward from both sides of the snap-fit ​​plate 43. Two adjacent snap-fit ​​plates 43 are respectively snapped onto the two sides of one end of the electronic price tag that is snapped onto the lower hook 114 and the upper hook 115 of the electronic price tag.

[0046] Among them, the two ends of the card strip 41 are symmetrically fixed with end sliding blocks 411, and the two end sliding blocks 411 slide on the upper slot rib 111 and the lower slot rib 112 respectively.

[0047] Furthermore, two slide rods 431 are symmetrically fixed to one side of the snap-fit ​​plate 43. The slide rods 431 are slidably inserted into the extension compartment 42. An end limiting piece 432 is fixed to the end of the slide rods 431 inserted into the extension compartment 42. A spring 433 is sleeved on the slide rods 431. The two ends of the spring 433 abut against the end limiting piece 432 and the extension compartment 42, respectively.

[0048] Therefore, in practical use, before installing the electronic price tag onto the lower hook 114 and upper hook 115, the two independent snap-fit ​​components 4 can be pre-positioned to a suitable location. Then, the electronic price tag is installed onto the lower hook 114 and upper hook 115, with the two independent snap-fit ​​components 4 positioned on the left and right sides of the electronic price tag respectively. Then, the snap-fit ​​plate 43 is pulled outwards, causing the inner side of the snap-fit ​​plate 43 to press against the outer side of the electronic price tag mounting location. Due to the elastic force of the spring 433, the snap-fit ​​plate 43 will elastically press against the electronic price tag. Similarly, the snap-fit ​​plate 43 on the other side is also elastically pressed against the electronic price tag. At the installation location of the electronic price tag, this design creates a left-right elastic fixation effect within the lower hook 114 and upper hook 115. Therefore, when it is necessary to remove one of the electronic price tags, the upper hook 115 can be safely moved outwards, and the independent locking components 4 on both sides can be moved to the sides respectively, allowing the electronic price tag to detach from the guide rail. During this process, even if the upper hook 115 moves outwards as a whole, the other remaining electronic price tags are elastically fixed by the independent locking components 4 on both sides and will not loosen. Therefore, this design greatly improves the stability and safety of the electronic price tags on the guide rail.
