Description

Technical Field

[0001] This utility model relates to the field of background panel technology, specifically a replaceable background panel structure for display cases. Background Technology

[0002] Replaceable backdrops for display cases are background components that can be easily replaced according to display needs. Common types include electronic screens with replaceable images and replaceable decorative panels. They can also be classified by material into rigid boards, textiles, paper, metal, and other materials. They are mainly used to optimize the visual effect of the display case, highlight the characteristics of the exhibits, and enhance the attractiveness of the display.

[0003] As a platform for displaying items, a display case is divided into multiple rectangular spaces by partitions.

[0004] To ensure a good visual experience, display cases use different colors and various layouts to achieve a comfortable viewing experience. To enhance the aesthetics of the items placed in the individual spaces within each display case, a backdrop is installed in each space to highlight the items. Typically, during the manufacturing and installation process, the backdrop style is fixed to the display case's compartments based on the user's pre-selection. However, users may experience aesthetic fatigue after prolonged use of display cases with fixed backdrops, and it is inconvenient for users to replace the fixed backdrops. Therefore, this paper proposes a replaceable backdrop structure for display cases to address these issues. Utility Model Content

[0005] The purpose of this utility model is to provide a replaceable background panel structure for display cases, so as to solve the problem that in the process of manufacturing and installing display cases, the style of the background panel is selected by the user and then fixed in the partition space of the display case. Users are prone to aesthetic fatigue when using display cases with fixed background panels for a long time, but the background panel fixed to the display case is not convenient for users to replace.

[0006] To achieve the above objectives, this utility model provides the following technical solution:

[0007] A replaceable backdrop structure for a display case includes a backdrop panel and a backing plate assembly. The backing plate assembly is fixedly connected to the outer side of the backdrop panel. The backing plate assembly includes a backing plate body.

The control component includes a rotating shaft. A rotating rod is fixedly connected to the outer side of the rotating shaft. A rotating rod is fixedly connected to the inner side of the rotating shaft. A first positive magnet is fixedly connected to the inner side of the rotating shaft. A transverse assembly is slidably connected to the inner side of the backing plate body. The transverse assembly includes a transverse sliding rod. A transverse positioning rod is fixedly connected to the end of the rod away from the center of the backing plate body. A second positive magnet is fixedly connected to the end of the transverse sliding rod near the center of the backing plate body. A longitudinal component is slidably connected to the inner side of the backing plate body. The longitudinal component includes a longitudinal sliding rod. A longitudinal positioning rod is fixedly connected to the end of the longitudinal sliding rod away from the center of the backing plate body. A second negative magnet is fixedly connected to the end of the longitudinal sliding rod near the center of the backing plate body. The outer side of the positioning pin engages with the inner side of the metal panel. A splicing panel is fixedly connected to the side of the metal panel away from the center of the backing plate body.

[0008] As a further optimization of this utility model, the following features are provided: the thickness of the scene panel is the same as the thickness of the splicing panel; the splicing panel is embedded in a circular through hole in the center of the scene panel; the front and rear ends of the scene panel are on the same plane as the front and rear ends of the splicing panel; and the upper, lower, left, and right sides of the scene panel are on the same plane as the horizontal positioning rod and the vertical positioning rod, respectively.

[0009] As a further optimization of this utility model, there are four positioning pins in total. The positioning pins are evenly arranged in the annular grooves opened on the inner side of the backing plate body. The positioning pins are located outside the range of rotation of the rotating rod around the axis of rotation. The positioning pins are adapted to the four pin holes evenly opened on the inner side of the metal panel.

[0010] As a further optimization of this utility model, the metal panel is fully embedded in the annular groove on the inner side of the backing plate body, and a cross-shaped slot is provided on the inner side of the metal panel to match the rotating rod. The thickness of the metal panel is the same as the thickness of the rotating rod, and the side of the metal panel away from the splicing panel is in close contact with the inner side of the backing plate body.

[0011] As a further optimization of this utility model, the number of the first positive magnet and the number of the first negative magnet are both two. The first positive magnet and the first negative magnet are the same size and shape. The two first positive magnets are symmetrically arranged on the rotating shaft. The straight line from the first positive magnet to the axis of rotation is perpendicular to the straight line from the first negative magnet to the axis of rotation. The first positive magnet and the first negative magnet rotate around the axis of rotation inside the back plate body.

[0012] As a further optimization of this utility model, the number of both the transverse and longitudinal components is two. The two transverse components are symmetrically arranged on the outer side of the backing plate body, and the two longitudinal components are symmetrically arranged on the outer side of the backing plate body. Both the transverse and longitudinal slide rods are pentagonal prism rods. Both the transverse and longitudinal slide rods slide on the inner side of the backing plate body. The transverse and longitudinal slide rods are respectively located at the center positions of the transverse positioning rod and the longitudinal positioning rod.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] In this invention, convenient installation and stable fixation are achieved through the clever synergy of positioning pins, rotating shafts, rotating rods, and metal panels. The core of this design lies in the interaction between the magnets and the cooperation between the positioning pins and the metal panels. The background panel has a smooth overall surface, and the spliced ​​panels blend naturally into the display panel, without affecting aesthetics and fitting tightly against the inner wall of the display case. The positioning pins are evenly distributed on the inner side of the backing panel body, ensuring a stable connection of the metal panels, avoiding mutual interference during installation and disassembly, and guaranteeing accurate positioning. The metal panels fit tightly against the backing panel body, and the "+" shaped slots and rotating rods... The design ensures the rotating rod rotates normally while preventing it from rotating arbitrarily, enhancing stability. The symmetrical layout of the magnets and the control of the magnetic pole direction effectively utilize magnetic force to control the movement of the positioning rod, achieving the fixing and release of the background panel. It is easy to operate and highly stable. The pentagonal prism-shaped slide bar prevents rotation during sliding, ensuring the linear movement of the positioning rod, improving installation accuracy and reliability. The pentagonal slide rail is connected to the rotation range of the magnets, ensuring effective transmission of magnetic force to push the positioning rod to move and fix the background panel. This ensures the efficient operation of the magnetic control system and facilitates the user's replacement of the display case's background panel. Attached Figure Description

[0029] 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.

[0030] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to this application. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of features, steps, operations, devices, components, and / or combinations thereof.

[0031] Please see Figures 1-8 This utility model provides a technical solution:

[0032] A replaceable backdrop structure for a display case includes a backdrop panel 1 and a backing plate assembly 2. The backdrop panel 1 is fixedly connected to the outer side of the backing plate assembly 2. The backing plate assembly 2 includes a backing plate body 21. A positioning pin 22 is fixedly connected to the inner side of the backing plate body 21. A control assembly 23 is rotatably connected to the inner side of the backing plate body 21. The control assembly 23 includes a rotating shaft 231. A rotating rod 232 is fixedly connected to the outer side of the rotating shaft 231. A first positive magnet 233 is fixedly connected to the inner side of the rotating shaft 231. A transverse assembly 24 is slidably connected to the inner side of the backing plate body 21. The transverse assembly 24 includes a transverse slide rod 241. A transverse positioning rod 242 is fixedly connected to one end of the backing plate body 21 away from the center. A second positive magnet 243 is fixedly connected to one end of the transverse sliding rod 241 near the center of the backing plate body 21. A longitudinal component 25 is slidably connected to the inner side of the backing plate body 21. The longitudinal component 25 includes a longitudinal sliding rod 251. A longitudinal positioning rod 252 is fixedly connected to one end of the longitudinal sliding rod 251 away from the center of the backing plate body 21. A second negative magnet 253 is fixedly connected to one end of the longitudinal sliding rod 251 near the center of the backing plate body 21. The outer side of the positioning pin 22 engages with the inner side of the metal panel 26. A splicing panel 27 is fixedly connected to one side of the metal panel 26 away from the center of the backing plate body 21.

[0033] As a further implementation of this solution, the thickness of the background panel 1 is the same as that of the splicing panel 27. The splicing panel 27 is embedded in the circular through hole in the center of the background panel 1. The front and rear ends of the background panel 1 and the front and rear ends of the splicing panel 27 are on the same plane. The upper, lower, left and right sides of the background panel 1 are on the same plane as the horizontal positioning rod 242 and the vertical positioning rod 252, respectively. This design can ensure the flatness of the overall surface of the background panel, so that the splicing panel 27 can be naturally integrated into the background panel 1. The overall aesthetics and display effect will not be affected by the difference in thickness or uneven position. At the same time, it is also conducive to the tight fit between the background panel and the inner wall of the display cabinet partition.

[0034] As a further implementation of this solution, there are four positioning pins 22. The positioning pins 22 are evenly arranged in the annular grooves opened on the inner side of the backing plate body 21. The positioning pins 22 are located outside the range of rotation of the rotating rod 232 around the axis of the rotating shaft 231. The positioning pins 22 are adapted to the four pin holes evenly opened on the inner side of the metal panel 26. This layout can ensure that the metal panel 26 is stably connected to the backing plate body 21. The positioning pins 22 are outside the rotation range of the rotating rod 232, avoiding mutual interference between the positioning pins 22 and the rotating rod 232 when operating, ensuring the smooth installation and disassembly process of the metal panel 26, as well as the accuracy of the positioning of the background plate during the fixing process.

[0035] As a further implementation of this solution, the metal panel 26 is fully embedded in the annular groove opened on the inner side of the backing plate body 21. The inner side of the metal panel 26 has a cross-shaped slot that matches the rotating rod 232. The thickness of the metal panel 26 is the same as the thickness of the rotating rod 232. The side of the metal panel 26 away from the splicing panel 27 is in close contact with the inner side of the backing plate body 21. This design allows the metal panel 26 to fit tightly against the inner side of the backing plate body 21. Its cross-shaped slot cooperates with the rotating rod 232, which can not only ensure that the rotating rod 232 can rotate normally when needed, but also play a certain limiting role on the rotating rod 232 after the metal panel 26 is installed, preventing the rotating rod 232 from rotating arbitrarily, which is conducive to maintaining the stability of the background plate's fixed state.

[0036] As a further implementation of this solution, there are two first positive magnets 233 and two first negative magnets 234. The first positive magnets 233 and the first negative magnets 234 are the same size and shape. The two first positive magnets 233 are symmetrically arranged on the rotating shaft 231. The straight line from the first positive magnet 233 to the axis of the rotating shaft 231 is perpendicular to the straight line from the first negative magnet 234 to the axis of the rotating shaft 231. The first positive magnets 233 and the first negative magnets 234 rotate around the axis of the rotating shaft 231 inside the back plate body 21. By controlling the position and direction of the magnets, the movement of the horizontal positioning rod 242 and the vertical positioning rod 252 can be effectively controlled by magnetic force to achieve the fixation and release of the background plate. The operation is simple and the stability is high.

[0037] As a further implementation of this solution, there are two horizontal components 24 and two vertical components 25. The two horizontal components 24 are symmetrically arranged on the outside of the backing plate body 21, and the two vertical components 25 are symmetrically arranged on the outside of the backing plate body 21. Both the horizontal slide rod 241 and the vertical slide rod 251 are pentagonal prism rods. Both the horizontal slide rod 241 and the vertical slide rod 251 slide inside the backing plate body 21. The horizontal slide rod 241 and the vertical slide rod 251 are respectively located at the center of the horizontal positioning rod 242 and the vertical positioning rod 252. This design allows the horizontal components 24 and the vertical components 25 to slide stably inside the backing plate body 21. The shape of the pentagonal prism rods can prevent unnecessary rotation of the slide rods during the sliding process, ensuring the linearity of the movement of the horizontal positioning rod 242 and the vertical positioning rod 252, thereby accurately fitting with the inner wall of the display cabinet partition and improving the accuracy and reliability of the background plate fixing installation.

[0038] As a further implementation of this scheme, the second positive magnet 243 and the second negative magnet 253 are the same size and shape. The second positive magnet 243 and the second negative magnet 253 maintain a distance from the first positive magnet 233 or the first negative magnet 234, respectively. The pentagonal slide where the second positive magnet 243 and the second negative magnet 253 are located is connected to the space within the rotation range of the first positive magnet 233 and the first negative magnet 234. This arrangement is conducive to the effective transmission of magnetic force. When the rotating shaft 231 drives the first magnet to rotate, the second positive magnet 243 and the second negative magnet 253 can be accurately moved by the repulsive force of the same pole magnetic force, thereby pushing the horizontal positioning rod 242 and the vertical positioning rod 252 to move, realizing the fixing function of the background plate and ensuring the efficient operation of the entire magnetic control system.

[0039] Workflow: When using this backdrop panel on a display case, and when it needs to be moved, select a backdrop panel slightly smaller than the space of the display case's partition. Use a strong magnet to approach the splicing panel 27, causing the metal panel 26, which is fixedly connected to the splicing panel 27, to be attracted by the strong magnet and detached from the groove on the inner side of the backing plate body 21. This exposes the control component 23 hidden under the splicing panel 27 and the metal panel 26. Then, after placing the backdrop panel in an appropriate position inside the display case's partition, rotate the rotating rod 232 in the groove of the backing plate body 21, causing the rotating rod 232 to rotate 90°. 32. The first positive magnet 233 and the first negative magnet 234 fixedly connected to the inner side of the backing plate body 21 are rotated by the rotating shaft 231. Originally, when the rotating shaft 231 is not rotating, the two first positive magnets 233 on the rotating shaft 231 are magnetically attracted to the second negative magnets 253 in the two longitudinal components 25 in the longitudinal direction, and the two first negative magnets 234 on the rotating shaft 231 are magnetically attracted to the second positive magnets 243 in the two transverse components 24 in the transverse direction. This ensures that the two transverse positioning rods 242 and the longitudinal positioning rods 252 are tightly attached to the four sides of the backing plate body 21. When the rotating shaft 231 rotates, the first positive magnet 233 and the first negative magnet 234 fixedly connected to the inner side of the rotating shaft 231 are rotated. After the positive magnet 233 and the first negative magnet 234 rotate 90°, the position of the first positive magnet 233 corresponds one-to-one with the position of the second positive magnet 243, and the position of the first negative magnet 234 corresponds one-to-one with the position of the second negative magnet 253. Therefore, due to the principle of repulsion between like magnetic forces, both the second positive magnet 243 and the second negative magnet 253 move away from the center of the rotating shaft 231. Consequently, the second positive magnet 243 and the second negative magnet 253 push the horizontal positioning rod 242 and the vertical positioning rod 252 towards the inner wall of the display case partition where the background panel is located, and press against it, so as to... This achieves the fixed placement of the background panel. Finally, the metal panel 26 and splicing panel 27 are reinstalled on the inner side of the backing plate body 21. At the same time, the pin holes on the inner side of the metal panel 26 correspond one-to-one with the positioning pins 22 in four directions and are re-engaged. After the metal panel 26 is installed, the rotating rod 232, which rotates 90°, is still engaged and restricted on the inner side of the metal panel 26. The metal panel 26 is fixed and restricted by the positioning pins 22, thereby ensuring the stability of the repulsive force between the first positive magnet 233 and the first negative magnet 234 on the second positive magnet 243 and the second negative magnet 253, respectively, and preventing the rotating rod 232 from rotating back, thus realizing the effective replacement of the display case background panel.

[0040] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
