Description

Technical Field

[0001] This utility model relates to the field of display pendants, and in particular to a buckle display pendant with a stable connection structure. Background Technology

[0002] Display hangers are electronic display devices with information transmission and reception capabilities, primarily used in supermarkets, convenience stores, pharmacies, and other similar establishments to display price information. Placed on shelves, they replace traditional paper price tags. Each electronic shelf tag connects to the store's computer database via wired or wireless network, displaying the latest product information on its screen. Electronic shelf tags effectively integrate the shelf into a computer program, eliminating the need for manual price tag changes and ensuring price consistency between the checkout counter and the shelf. Display hangers work with shelf-mounted components, allowing for convenient attachment and secure use.

[0003] Current display mounts typically consist of a housing, a control module, a display screen, and a transparent protective sheet. The display screen is electrically connected to the control module, and both are housed within the housing's cavity. The transparent protective sheet is located on the upper surface of the housing, which has positioning protrusions. These protrusions engage with positioning grooves on the shelf to secure the display mount. While this structure is simple and provides basic information display functionality, it suffers from several drawbacks. During use, the placement of goods can cause the shelf to vibrate, leading to further vibrations in the display mount. The connection structure is not robust enough, and the positioning protrusions can easily detach from the positioning grooves, causing the display mount to fall and become damaged. Furthermore, the product's waterproof performance is poor. Accidental liquid spillage can allow liquid to seep into the housing cavity through the gap between the transparent protective sheet and the housing, damaging the display mount. The product quality is also generally low, with a short lifespan, failing to meet current needs. Therefore, it is necessary to research a new technical solution to address these issues. Utility Model Content

[0004] In view of the above, this utility model addresses the shortcomings of existing technologies. Its main purpose is to provide a buckle display pendant with a stable connection structure. It can effectively solve the problems of existing technologies, such as: during use, the placement of goods sometimes causes the shelf to vibrate, which in turn causes the display pendant to vibrate; the connection structure of the display pendant is not stable enough; the positioning protrusion is easy to detach from the positioning groove, causing the display pendant to fall and be damaged; the waterproof performance of the product is poor; when liquid is accidentally spilled on the display pendant, the liquid can easily flow into the receiving cavity through the gap between the transparent protective sheet and the outer shell, causing damage to the display pendant; the product quality is generally poor and the service life is short.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:
