[0040] See also Figures 1 to 5 This embodiment provides a back panel electronic price label guide rail, including:

[0041] The guide rail fixing mechanism 10, the left end of which is used to be fixedly connected with an external support structure to fix the guide rail; the external support structure can be a wall, a shelf, a horizontal bar, a vertical bar or a desktop. The guide rail fixing mechanism 10 can be configured with different types of guide rail fixing mechanisms 10 according to different external support structures. Preferably, the guide rail fixing mechanism 10 can adopt an adhesive mechanism, and the external support structure is adhered to achieve fixation by the adhesive mechanism. The adhesive mechanism can adopt double-sided tape, nylon Velcro, etc. When the tape is adopted, the adhesive on the surface of the tape is used to make the back of the guide rail adhere to the contact surface between the wall, desktop or shelf to achieve fixation. When the nylon Velcro is used, the A side and the B side of the nylon Velcro can be set on the back of the guide rail and the wall, desktop or shelf correspondingly, and finally the nylon A side and the nylon B side are adhered to achieve fixation. The adhesive mechanism is used for fixation, which has low cost, simple structure, convenient fixing process, only one adhesive plane is needed to achieve fixation, and high compatibility. Preferably, in order to facilitate the subsequent removal of the guide rail or the position of the movable guide rail, the guide rail fixing mechanism 10 can adopt a clamping mechanism, which clamps the external support structure to achieve fixation. The clamping mechanism can refer to an electronic price tag assembly device disclosed in the patent document with announcement number CN214890368U. The layer fixing mechanism in the new type is equivalent to the clamping mechanism, which clamps the layer through the other end of the first clamping part and the second clamping part. The elastic member can allow the second clamping part to push the layer upward, so that the layer is fixed. The fixing mechanism can be firmly clamped on the shelf, reducing the possibility of the shelf fixing mechanism shaking on the shelf, so that the electronic price tag assembly device can adapt to a variety of shelf boards; for example, a high-strength multifunctional price tag guide rail disclosed in the patent document with publication number CN113380132A, the cargo plate fixing plate in the patent document is equivalent to the guide rail fixing mechanism, through the connecting part and the lower spring sheet, the elastic clamping mouth between the upper pressure part and the lower top plate can be realized, the shelf board or cargo board can be clamped, and high-strength clamping can be achieved. It should be noted that, including but not limited to this embodiment, all connections except for the easily deformable connection formed by flexible materials are actually fixed connections. The connection is essentially two hard plastics connected together by hard plastics (such as hard PVC plastics), and the connection will maintain the relative position of the plate-like structure to which it is connected (such as the transparent fixing plate 201, the upper hook plate 202, the lower main hook plate 203, etc. described below).

[0042] It should be noted that the left end and the right end described in the present invention are described based on the cross section of the guide rail. Since the price tag guide rail is a long strip, such as Figure 1 As shown, in the three-dimensional structure, the left end and the right end correspond to the left edge and the right edge, and the upper end and the lower end correspond to the upper edge and the lower edge.

[0043] The price tag fixing mechanism 20, the right end of the guide rail fixing mechanism 10 is connected to the back of the price tag fixing mechanism 20, and the front of the price tag fixing mechanism 20 is used to fix the price tag. It should be noted that the price tag fixing mechanism 20 described in this embodiment is not limited to fixing electronic price tags, and can also be used to fix paper price tags (or thin price tags). The price tag fixing mechanism 20 includes a transparent fixing plate 201, an upper hook plate 202 and a lower hook plate. The transparent fixing plate 201, the upper hook plate 202 and the lower main hook plate 203 are combined to form a C-shaped structure for fixing the price tag; when the price tag fixing mechanism 20 is used to fix an electronic price tag (thick price tag), the upper hook plate 202 and the lower hook plate can be configured in shape according to the thickness of the electronic price tag, that is, the gap between the end of the upper hook plate 202 and the transparent fixing plate 201 should not be less than the upper edge of the electronic price tag, and the gap between the end of the lower hook plate and the transparent fixing plate 201 should not be less than the lower edge of the electronic price tag, and the upper hook plate 202 and the lower hook plate can respectively hook the upper and lower edges of the electronic price tag to fix the electronic price tag. Similarly, when the price tag fixing mechanism 20 is used to fix a paper price tag (thin price tag), the specific shapes and sizes of the upper hook plate 202 and the lower hook plate can be adaptively adjusted, wherein the lower hook plate can appropriately expand the support width, and only needs to be able to support the lower edge of the paper price tag, and the end of the upper hook plate 202 can be bent inward to form a space into which the upper edge of the paper price tag can be inserted, thereby achieving the function of stably fixing the paper price tag.

[0044] The back of the transparent fixed plate 201 is provided with a paper clamping mechanism 30, and the paper clamping mechanism 30 is used to fix the information display surface and make the information display surface fit to the back of the transparent fixed plate 201. The paper clamping mechanism 30 can adopt a groove-shaped structure with an upper opening or a left and right opening. By arranging a structural plate on the back of the transparent fixed plate 201, the lower end of the structural plate is connected to the lower end of the transparent fixed plate 201, and the structural plate is relatively parallel to the transparent fixed plate 201, the background cardboard 60 can be inserted from the upper opening or the left and right openings to form the price tag background color. If the structural plate in the above embodiment is open to the left and right, in order to fix the background cardboard 60, the structural plate itself needs a larger area, and the material cost is higher. If it is open to the top, it is necessary to give up the upper space for inserting the background cardboard 60, and the softer background cardboard 60 may not be fixed. Therefore, the structural plate can also adopt a grid structure to reduce the material cost, and the background cardboard 60 can be inserted laterally at any position, but this embodiment still has the problem of inconvenient removal of background jams.

[0045] Therefore, in order to save material costs and stably fix the background cardboard 60, preferably, the paper clamping mechanism 30 includes an upper pressing plate 301 and a lower pressing plate 302, the upper end of the upper pressing plate 301 is connected to the upper end of the transparent fixing plate 201, and the lower end of the lower pressing plate 302 is connected to the lower end of the transparent fixing plate 201. In this embodiment, the lower part of the background cardboard 60 is inserted between the lower pressing plate 302 and the transparent fixing plate 201, and the upper part is inserted between the upper pressing plate 301 and the transparent fixing plate 201. The upper pressing plate 301 and the lower pressing plate 302 only need a smaller length to better fix the background cardboard 60. In order to make the background cardboard 60 fit the back of the transparent fixing plate 201 to present a better background color effect, the upper pressing plate 301 and the lower pressing plate 302 can be configured to be parallel to the transparent fixing plate 201 and the gap is slightly smaller than the background cardboard 60, so as to achieve the above-mentioned purpose. Alternatively, in order to facilitate the insertion of the background cardboard 60 without affecting its fit with the transparent fixing plate 201, the gaps between the upper pressing plate 301 and the lower pressing plate 302 and the transparent fixing plate 201 can be appropriately enlarged, and the lower end of the upper pressing plate 301 and the upper end of the lower pressing plate 302 are both against the back of the transparent fixing plate 201. At the same time, the upper pressing plate 301 and the lower pressing plate 302 are flexibly connected to the transparent fixing plate 201. When the background cardboard 60 is inserted, the upper pressing plate 301 and the lower pressing plate 302 can be appropriately tilted outward, and then rebound and press the background cardboard 60 to achieve fixation. Furthermore, in order to facilitate the insertion of the background cardboard 60, the lower end of the upper pressing plate 301 is bent in the direction away from the transparent fixing plate 201 and the bending part abuts against the back side of the transparent fixing plate 201; and / or the upper end of the lower pressing plate 302 is bent in the direction away from the transparent fixing plate 201 and the bending part abuts against the back side of the transparent fixing plate 201. In this embodiment, when the background cardboard 60 is inserted, there is no need to manually lift the upper pressing plate 301 or the lower pressing plate 302. It only needs to push the background cardboard 60 in. The edge of the background cardboard 60 contacts the bending part of the lower pressing plate 302 and slides downward along the curve of the bending part to the inside for fixation. The same is true for the upper pressing plate 301, which is convenient and quick.

[0046] In the aforementioned embodiment, the paper clip mechanism 30 is used to fix background paper with different colors, so that the background color of the price tag can be flexibly configured to facilitate sales activities. In actual business activities, in addition to using the background color as a striking mark, it is often necessary to add personalized information for explanation, such as discount information, product attribute information, product inventory information, etc. In this case, it is necessary to provide an additional information display surface. Therefore, based on the aforementioned embodiment, the transparent fixing plate 201 is further extended downward, and the lower hook plate is set in the middle of the transparent fixing plate 201. Figure 1As shown, after the transparent fixing plate 201 extends downward, the lower pressing plate 302 is still at the lower back of the transparent fixing plate 201, and the lower hook plate does not extend with the transparent fixing plate 201. Of course, the position of the lower hook plate is not the middle position of the transparent fixing plate 201, and its specific height position needs to match the price tag used. As a result, two information display areas are formed on the front of the transparent fixing plate 201. The area between the upper hook plate 202 and the lower hook plate is still used to fix the price tag, that is, the price tag information display area, and the area below the lower hook plate is an additional information display area. In this example, the height of the background cardboard 60 that can be loaded is increased. After the background cardboard 60 is inserted into the paper clamping mechanism 30, the upper part overlapping with the price tag information display area is the background color of the price tag, and the lower part overlapping with the additional information display area can be used as an information display area. By adding specific information to the information display area of ​​the background cardboard 60, the sales information of the product can be supplemented.

[0047] The novel price tag fixing mechanism 20 is composed of a transparent fixing plate 201, an upper hook plate 202 and a lower hook plate. A paper clamping mechanism 30 is provided on the back of the transparent fixing plate 201. Background paperboards 60 of different colors are fixed in the paper clamping mechanism 30 to flexibly configure the background color of the price tag, so as to facilitate eye-catching identification of the goods. In addition, an additional information display area is formed by extending the transparent fixing plate 201 downward, without the need to add a clamping fixing mechanism. The overall structure is simple and convenient to use.

[0048] In some embodiments, a flexible pad 50 is further included, and the flexible pad 50 is disposed on the inner upper surface of the lower hook plate. The flexible pad 50 can be made of flexible plastic material, and the upper surface of the flexible pad 50 can be used to contact with the thick price tag and provide buffering, so as to facilitate the fixing of the thick price tag. At the same time, a gap is left between the right side of the flexible pad 50 and the end of the lower hook plate, and the gap can be used to insert a paper price tag, thereby improving practicality.

[0049] In some embodiments, the guide rail fixing mechanism 10 is flexibly connected to the price tag fixing mechanism 20. This allows the guide rail fixing mechanism 10 and the price tag fixing mechanism 20 to rotate relative to each other at a certain angle, which is convenient for installation. The guide rail fixing mechanism 10 and the price tag fixing mechanism 20 are flexibly connected by a flexible connecting material, so that after the guide rail is fixed to the external support structure, the price tag fixing mechanism 20 can be rotated at a certain angle relative to the guide rail fixing mechanism 10. According to different fixing heights, the front of the price tag fixing mechanism 20 is adjusted to rotate to an angle suitable for observation, thereby improving compatibility and convenience. Furthermore, a bevel pressure plate 40 is also included, the left end of which is connected to the guide rail fixing mechanism, and the right end of the bevel pressure plate 40 can be pressed against the back of the transparent fixing plate 201 as the guide rail fixing mechanism 10 and the price tag fixing mechanism 20 rotate relative to each other. The oblique pressure plate 40 can apply pressure to the background paperboard 60 on the back of the transparent fixed plate 201 , so that the background paperboard 60 and the transparent fixed plate 201 can be more closely fitted, thereby improving the display effect and facilitating observation.

[0050] In some embodiments, the guide rail fixing mechanism 10 includes an upper claw plate 101 and a lower claw plate 102, and the upper claw plate 101 and the lower claw plate 102 are both provided with clamps and the two clamps are arranged in opposite directions. The upper claw plate 101 and the lower claw plate 102 can be used to fix the shelf with a hook and groove structure, making the guide rail more stable.

[0051] In some embodiments, the guide rail fixing mechanism is provided with a groove 70. The shape or position of the groove can be adjusted according to the specific structure of the external support structure. Figure 5 The stability of the guide rail is improved by engaging the groove with the protruding structure of the layer plate.

[0052] In certain embodiments, see Figure 6 , further comprising a protrusion 80, which is disposed on the outer side of the upper hook plate. The protrusion is used to provide a force application point. When removing the price tag, an upward force is applied to the protrusion, and the protrusion drives the upper hook plate to move upward, so that the price tag is separated from the price tag fixing mechanism, which is convenient for removal.

[0053] It should be noted that although the above embodiments have been described in this article, this does not limit the scope of patent protection of the utility model. Therefore, based on the innovative concept of the utility model, changes and modifications to the embodiments described in this article, or equivalent structural or equivalent process changes made using the contents of the utility model specification and drawings, directly or indirectly applying the above technical solutions to other related technical fields are all included in the scope of protection of the utility model patent.
