Description

Technical Field

[0001] This utility model relates to the field of display rack technology, specifically a modular electronic display advertising display rack. Background Technology

[0002] Existing electronic display advertising stands are mainly divided into two types: large screens fixed to walls and small, floor-standing mobile screens. Large screens fixed to walls are mostly used for long-term displays and are suitable for fixed settings such as shopping malls or exhibition halls; while small, floor-standing mobile screens are often carried by exhibitors for temporary events such as exhibitions. Floor-standing mobile screens typically consist of a main frame and a screen. During transportation, the screen and main frame are fixed together. To ensure stability during transport, the main frame needs to be secured. Since the screen cannot be disassembled and therefore cannot be protected separately, it is easily damaged during transportation. If the display screen is completely disassembled for transport, multiple bolts are needed to fix the screen to the main frame during assembly in the exhibition area. This method of fixing can easily lead to loose bolts or screen misalignment during frequent disassembly and installation, affecting the display effect. Utility Model Content

[0026] To better explain and facilitate understanding of the present invention, a detailed description of the invention is provided below with reference to the accompanying drawings and specific embodiments. This utility model discloses a modular electronic display advertising display stand. The display screen is disposed within a cavity, and an assembly is disposed within the cavity. The assembly includes a door-shaped frame and a back panel. A positioning insert is provided between the frame and the door-shaped frame; a back panel crossbeam is provided on the back panel, and the frame overlaps the back panel crossbeam and is fixed by a fixing bolt. By designing the display screen and the main body of the display stand to be detachably connected, the screen can be individually protected during transportation. Multiple fixing methods are formed for the frame through the sliding locking limit of sliders and tracks, and the insertion locking limit of positioning parts and sockets, combined with the tightening of a fixing bolt, making installation and disassembly convenient and quick.

[0027] The technical solutions of the present invention 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 invention, and not all embodiments. Various changes can be made to the implementation scheme as long as the effects of the present invention can be achieved.

[0028] Those skilled in the art can connect the components in this case sequentially. The specific connection and operation sequence should refer to the working principle described below. The detailed connection methods are well-known technologies in the field. The working principle and process are mainly described below.

[0029] like Figures 1 to 6As shown in the figure, this application proposes a modular electronic display advertising display stand, including a base unit and an electronic screen unit. The base unit includes a display stand 1, and the electronic screen unit includes a display screen 2. A beam arm is provided within the display stand 1, dividing the interior of the display stand 1 into a cavity 3 and a control device receiving cavity 20. The display screen 2 is disposed within the cavity 3. In one configuration, the beam arm is horizontally positioned, so that the cavity 3 and the control device receiving cavity 20 are vertically aligned; alternatively, the beam arm can also be vertically positioned, so that the cavity 3 and the control device receiving cavity 20 are horizontally aligned.

[0030] In addition, such as Figure 6 As shown, an opening 4 is made on the beam arm to connect the cavity 3 and the control equipment cavity 20. The opening 4 is used to introduce the cable in the control equipment cavity 20 into the cavity 3 and plug it into the display screen 2 to realize the connection between the control equipment and the display screen.

[0031] In this embodiment, as Figure 1 As shown, the cavity 3 is equipped with an assembly, and the display screen 2 is fixedly provided with a frame 17 around its periphery. During disassembly and assembly, the frame 17 can be detachably connected to the assembly, so that the display screen 2 can be detachably connected to the display stand 1, realizing separate transportation and rapid assembly at the use site.

[0032] Specifically, the assembly in this embodiment includes a door-shaped frame 6 and a back plate 5. When the display screen 2 is installed, the weight of the display screen 2 is distributed on the door-shaped frame 6 and the back plate 5, avoiding local stress concentration and preventing the risk of deformation of the door-shaped frame and the back plate during use. The back plate 5 has an opening 10 in the middle, which exposes the back of the display screen 2 in the space of the cavity 3. After the back plate of the display stand 1 is removed, the operation of fixing the display screen 2 and the wiring operation can be performed on the rear side of the display stand 1.

[0033] For example, such as Figure 1 As shown, the portal frame 6 is located circumferentially within the cavity 3. The bottom sides of the portal frame 6 are bent inwards to form bottom crossbeams 13 for supporting the frame 17. A positioning insert is provided between the frame 17 and the portal frame 6, allowing the display screen 2 to be positioned by insertion when placed within the cavity 3. The back plate 5 is located inside the portal frame 6, and a back plate crossbeam 7 is provided on the back plate 5. The frame 17 overlaps the back plate crossbeam 7 and is fixed by a fixing bolt 8. By positioning the frame 17 circumferentially within the cavity 3 using inserts, the number of bolts is reduced, improving installation efficiency.

[0034] like Figure 3 and Figure 6 As shown, a gap cavity 14 is formed between the opposite ends of the two bottom crossbeams 13, and the opening size of the gap cavity 14 is adapted to the opening 4.

[0035] The frame 17 includes a frame surrounding the display screen 2 and a crossbeam 16 located inside the frame. The middle part of the crossbeam 16 is fixed to the back plate crossbeam 7 by a fixing bolt 8. In this embodiment, the display screen 2 is positioned by plug-in insertion, and then the crossbeam 16 on the display screen 2 is fixed to the back plate crossbeam 7 by a fixing bolt 8. The positioning and pre-fixing by plug-in insertion combined with the fixing by a single fixing bolt 8 simplifies the installation and fixing steps and improves assembly efficiency.

[0036] Furthermore, leveling bolts 9 are provided on both sides of the back panel crossbeam 7, specifically on both sides of the fixing bolts 8. The top of the leveling bolts 9 abuts against the crossbeam 16. Before fixing the display screen 2, it is necessary to ensure that the leveling bolts 9 are retracted into the back panel crossbeam 7 to prevent them from protruding and causing them to abut against the crossbeam 16, thus affecting the placement of the display screen 2. It should be noted that the fixing bolts 8 are not tightened before leveling. The fixing bolts 8 are tightened only after the ideal level is achieved.

[0037] The plugin in this embodiment has two implementations. These two plugins can be set up independently or used together. The structure and installation relationship of the two plugins are described below.

[0038] In the first embodiment, the plug is disposed between the bottom crossbeam 13 and the frame 17, including a positioning member disposed on the bottom crossbeam 13 and an insertion hole 19 opened at the bottom of the frame 17. When the display screen 2 is placed in the cavity 3, the insertion hole 19 is fitted onto the positioning member during the process of the display screen 2 falling from top to bottom, so as to realize the purpose of the positioning member being inserted into the insertion hole 19 for positioning.

[0039] The positioning component is a post 15, comprising a rigid post 151 and a flexible sleeve 152 wrapped around the rigid post 151. The rigid post 151 is made of stainless steel, and the flexible sleeve 152 is made of rubber. The design of the flexible sleeve 152 allows an elastic buffer layer to be formed between the frame 17 and the rigid post 151. Simultaneously, when the leveling bolt 9 is used for horizontal adjustment, the display screen 2 will swing. At this time, the flexible sleeve 152 is compressed, causing it to deform, and the deformation of the flexible sleeve 152 provides the display screen 2 with room to swing.

[0040] In the second embodiment, the plug is disposed between the side wall of the frame and the frame 17, including a slide rail on the side wall of the frame and a slider 18 disposed on the side wall of the frame 17. When the display screen 2 is placed in the cavity 3, the slider 18 slides into the slide rail.

[0041] The slide includes a first opening 11 and a second opening 12. The first opening 11 is arranged along the depth direction of the cavity 3 and is open at one end. The second opening 12 is arranged along the longitudinal direction of the side wall of the portal frame 6 and communicates with the first opening 11. The arrangement directions of the first opening 11 and the second opening 12 are perpendicular to each other.

[0042] In this embodiment, when the display screen 2 is placed, the slider 18 on the side wall of the frame 17 enters laterally along the first opening 11, and falls into the second opening 12 when it slides above the second opening 12. At this time, the second opening 12 limits the front and rear direction of the slider 18, and when the leveling screw 9 is adjusted horizontally, the slider 18 is adjusted vertically in the second opening 12, which can provide swing space for the frame 17 and the display screen 2.

[0043] In another embodiment, the positioning element and the socket 19, as well as the slider 18 and the slide rail, can be used in combination. It should be noted that the positioning element and the second opening 12 in the slide rail must be on the same circumferential extension line of the frame 17. For example, when installing the display screen 2, the slider 18 on the side wall of the frame 17 first slides into the first opening 11. As the slider 18 falls downward in the second opening 12, the positioning element is simultaneously inserted into the socket 19, forming a double locking.

[0044] In this embodiment, the display screen 2 can be installed by sliding in and locking the slider 18 and the slide rail, as well as by inserting the positioning element and the socket 19, and by tightening a fixing bolt 8, forming multiple fixing methods for the frame 17, and the installation and disassembly are convenient and quick.

[0045] 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.
