Description

Technical Field

[0001] This invention relates to the field of display and advertising equipment technology, and in particular to a display rack and display device. Background Technology

[0002] Display devices, especially display displays, are commonly used in exhibition halls, shopping malls, libraries, museums, and other similar venues. With technological advancements, screen displays have gradually come into focus. The most common display medium in screen display devices is the electronic screen; however, these screens are typically large and fixed to building walls, making them immobile and unsuitable for applications requiring high mobility. Existing technologies also involve other display media, such as promotional posters and projection screens—non-actively emitting display media. However, the display racks supporting these media are often too simple and lack stability.

[0003] Therefore, how to develop a display device that is both mobile and flexible and compatible with common display media is a technical problem that is of common concern and urgently needs to be solved by those skilled in the art. Summary of the Invention

[0004] To address the shortcomings of the existing technologies, this invention discloses two technical solutions. The first technical solution is a display rack, which is not only flexible and stable but also has a strong sense of design and expandability. The second technical solution is a display device based on the first technical solution, which is compatible with different display media.

[0005] The first technical solution of the present invention is as follows:

[0006] A display rack is a square frame structure composed of crossbeams and columns, and a support is provided underneath the display rack.

[0007] Furthermore, the crossbeam includes a crossbeam body and end caps. The crossbeam body is formed by fastening a crossbeam shell and a crossbeam cap together. The end caps are installed at both ends of the crossbeam body. The crossbeam shell, the crossbeam cap, and the end caps form a hollow cavity.

[0008] In a more preferred technical solution, the column includes a slot that extends through the column along its length.

[0009] The joint between the beam and the column is also equipped with a connector.

[0010] Furthermore, the crossbeam includes an upper crossbeam and a lower crossbeam, which are respectively disposed at the upper and lower ends of the display frame.

[0011] The two ends of the beam cover are respectively provided with perforated windows.

[0012] Furthermore, the column includes a first side, a second side, a third side, and a fourth side.

[0013] The first and second sides are used to install and fix the display medium, the third side is provided with the slot, and the fourth side is provided with the mounting hole.

[0014] Furthermore, the card slot includes a first card slot and a second card slot, with the bottom of the card slot being the first card slot and the upper part of the card slot being the second card slot.

[0015] A first limiting part is provided between the first card slot and the second card slot; a second limiting part is provided at the top of the second card slot.

[0016] Furthermore, the display frame also includes a mounting pin, one end of which is inserted into the second slot and the other end of which is inserted into the crossbeam.

[0017] Furthermore, the display frame also includes a fixing strip, the fixing strip having an angular cross-section and including a first fixing surface and a second fixing surface, the fixing strip being installed on the first and second sides of the column.

[0018] Furthermore, the first fixing surface is provided with a snap-fit ​​part, and the second fixing surface is a holeless plane or a plane provided with multiple rows of evenly distributed holes.

[0019] When the second fixing surface is a plane with multiple rows of evenly distributed holes, the holes in the same row have the same size and specifications.

[0020] Furthermore, the second side surface is also evenly provided with multiple rows of grooves, and when the fixing strip is installed on the column, the snap-fit ​​part snaps into the groove.

[0021] Furthermore, the connector includes a first connector and a second connector.

[0022] The first connector is L-shaped and consists of a first connecting surface, a second connecting surface, a third connecting surface, and a fourth connecting surface.

[0023] The first connecting surface and the second connecting surface are aligned vertically and connected vertically to each other on their sides. The bottom edges of the first connecting surface and the second connecting surface are vertically connected to one end of the third connecting surface.

[0024] The fourth connecting surface is aligned left and right with the third connecting surface, and the lower surface of the third connecting surface is perpendicularly connected to the upper side of the fourth connecting surface.

[0025] Mounting holes are provided on the first, second, third, and fourth connecting surfaces.

[0026] Furthermore, the second connector includes a fifth connecting surface and a sixth connecting surface, which are integrally formed.

[0027] The fifth connecting surface is provided with a mounting hole and a first concave part, and the sixth connecting surface is an arc surface.

[0028] Furthermore, the bracket is provided with wheels at its bottom and a seventh connecting surface at its top, and the seventh connecting surface is provided with mounting holes and a second concave surface.

[0029] The second technical solution of the present invention is a display device based on the first technical solution, which includes a display frame and a display medium.

[0030] When the display device includes multiple display racks, the display device is composed of a new display rack assembled from multiple display racks and a display medium.

[0031] The display medium is set on the display rack or a new display rack.

[0032] Furthermore, the display medium is one of LED screen, LCD screen, projection screen, or promotional poster.

[0033] This invention discloses a display rack and display device with a strong sense of design and compatibility with different display media, such as electronic screens, projection screens, and posters. The technical solution features a wheeled support frame for flexible transport and stable support. Furthermore, this invention has strong scalability; multiple display racks can be combined to form a larger new display rack. Attached Figure Description

[0042] The present invention will now be described in further detail with reference to the accompanying drawings.

[0043] To better illustrate this embodiment, some components in the accompanying drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product; those skilled in the art will understand the omission of certain well-known structures and their descriptions in the drawings. The same or similar reference numerals correspond to the same or similar components.

[0044] In today's society, many occasions require displays or advertising, such as model shows, poster advertisements, and rotating electronic screens. Large electronic screens are generally fixed on the exterior walls of buildings because they take up a lot of space and are easily obstructed from indoors; therefore, they are rarely installed on interior walls. The function of large electronic screens on exterior walls is limited to simple advertising. For conveying rich visual effects or temporary displays on special occasions, large electronic screens are either inadequate or completely incapable.

[0045] The first technical solution disclosed in this invention is a display rack. This technical solution is compatible with different display media and is equipped with a wheeled support for flexible handling and stable support. The display rack also has strong scalability; its size can be adjusted according to the actual size of the display media, or multiple display racks can be combined to form a larger new display rack.

[0046] It should be noted that this technical solution is particularly suitable for transparent display media capable of displaying 3D holographic images, such as transparent LED holographic screens and transparent projection screens. At the same time, this technical solution is also compatible with other display media, such as non-transparent electronic screens and promotional posters.

[0047] Therefore, in the following embodiments, the display medium is a transparent LED holographic screen, which is used as an example to illustrate the technical solution of the present invention in detail.

[0048] Specific embodiments of the present invention are as follows: Example 1

[0049] like Figure 1 , Figure 2 and Figure 3As shown in the figure, this embodiment provides a display frame, which is a square frame structure composed of crossbeams 20 and columns 30, and a support 40 is provided under the display frame.

[0050] In a further technical solution of this embodiment, the crossbeam 20 includes a crossbeam body and an end cap 23. The crossbeam body is formed by fastening a crossbeam shell 21 and a crossbeam cover 22 together. Figure 4 As shown. The end caps 23 are installed at both ends of the crossbeam body, and the crossbeam shell 21, the crossbeam cover 22 and the end caps 23 form a hollow cavity.

[0051] It should be noted that when the display medium installed in this embodiment is an electronic screen, such as a transparent LED holographic screen, the cavity formed by the crossbeam housing 21, the crossbeam cover 22, and the end cover 23 houses the electrical module 11 that fixes and drives the electronic screen (e.g., Figure 2 As shown in the figure, the electrical module 11 can be a drive power supply or other related circuit structure, or a drive power supply and other related circuit structures, and this embodiment will not elaborate further on this point.

[0052] In this embodiment, the crossbeam 20 includes an upper crossbeam and a lower crossbeam, which are respectively disposed at the upper and lower ends of the display frame.

[0053] In this embodiment, a more preferred technical solution is provided, wherein the two ends of the crossbeam cover 22 are respectively provided with perforated windows, such as... Figure 4 As shown, the window not only facilitates heat dissipation for the electrical module 11 inside the cavity, but also serves a decorative purpose.

[0054] This implementation example Figure 5 As shown, the column 30 includes a slot 35 (not shown in the figure), which extends through the column 30 along its length.

[0055] In this embodiment, the column 30 includes a first side 31, a second side 32, a third side 33, and a fourth side 34.

[0056] In this embodiment, the first side 31 and the second side 32 are used to install and fix the display medium. The third side 33 in this embodiment is provided with the aforementioned slot 35. The fourth side 34 in this embodiment is provided with the mounting hole 71 (not shown in the figure).

[0057] In a further technical solution of this embodiment, the card slot 35 includes a first card slot 351 and a second card slot 352. Specifically, as follows... Figure 5 As shown, the bottom of the card slot 35 is the first card slot 351, and the upper part of the card slot 35 is the second card slot 352.

[0058] A first limiting part 353 is provided between the first slot 351 and the second slot 352. The first limiting part 353 is two protrusions symmetrically arranged in the middle of the two side walls of the slot 35. Specifically, as shown in the figure... Figure 5 As shown.

[0059] The second slot 352 is provided with a second limiting part 354 at its top. The second limiting part 354 is two protrusions symmetrically arranged at the top of the two side walls of the slot 35, as shown in the figure below. Figure 5 As shown.

[0060] This implementation example Figure 2 As shown, the display frame also includes a mounting pin 70, one end of which is inserted into the second slot 352 and the other end is inserted into the crossbeam 20, specifically into the insertion interface 25 at both ends of the crossbeam housing 21.

[0061] In this embodiment, the second slot 352 is used to position and engage the mounting pin 70 when installing the crossbeam 20 and the column 30; in this embodiment, the first slot 351 is used for wiring, storing exposed electrical wires or other aesthetically pleasing wires in the first slot 351, thereby making the entire display frame look neater and more beautiful.

[0062] This implementation example Figure 2 and Figure 6 As shown, the display frame also includes a fixing strip 50. The fixing strip 50 has an angular cross-section and includes a first fixing surface 51 and a second fixing surface 52. The fixing strip 50 is installed on the first side surface 31 and the second side surface 32 of the column 30.

[0063] Specifically, the first fixing surface 51 is provided with a snap-fit ​​part 511, and the second fixing surface 52 is a holeless plane or a plane with multiple rows of evenly distributed holes.

[0064] In this embodiment, when the second fixing surface 52 is a plane with multiple rows of evenly distributed holes, the holes in the same row have the same size and specifications, specifically as follows: Figure 6 As shown.

[0065] It should be noted that a row of holes near the first fixing surface 51 is used for mounting screws to fasten the fixing strip 50 to the column 30. The other holes are designed to avoid obstructing the pixels of the LED holographic screen, and the size of the holes matches the pixel size of the LED holographic screen.

[0066] In a more preferred embodiment, the second side 32 of the column 30 is further provided with multiple rows of grooves 321, such as... Figure 5As shown, when the fixing strip 50 is installed on the column 30, the snap-fit ​​part 511 snaps into the groove 321.

[0067] This implementation example Figure 2 and Figure 3 As shown, a connector is also provided at the joint between the crossbeam 20 and the column 30.

[0068] In this embodiment, the connector includes a first connector 60 and a second connector 80.

[0069] Specifically, such as Figure 7 As shown, the first connector 60 is L-shaped and consists of a first connecting surface 61, a second connecting surface 62, a third connecting surface 63, and a fourth connecting surface 64.

[0070] The first connecting surface 61 and the second connecting surface 62 are vertically aligned and connected vertically to each other on their sides. The bottom edges of the first connecting surface 61 and the second connecting surface 62 are vertically connected to one end of the third connecting surface 63. The fourth connecting surface 64 is horizontally aligned with the third connecting surface 63, and the lower surface of the third connecting surface 63 is vertically connected to the upper side of the fourth connecting surface 64.

[0071] Mounting holes 71 are provided on the first connecting surface 61, the second connecting surface 62, the third connecting surface 63 and the fourth connecting surface 64.

[0072] It should be noted that because the first connector 60 is used at the four corners, there are two specifications of the first connector 60. The second specification of the first connector 60 has an axisymmetric structure with the first connector 60 mentioned above, as shown in the figure below. Figure 2 As shown.

[0073] This implementation example Figure 8 As shown, the second connector 80 includes a fifth connecting surface 82 and a sixth connecting surface 83, which are integrally formed.

[0074] The fifth connecting surface 82 is provided with two rows of mounting holes 71, and the back of the fifth connecting surface 82 is provided with a first concave surface 81, wherein the first row of mounting holes 71 penetrates the first concave surface 81.

[0075] The sixth connecting surface 83 is an arc surface.

[0076] In a more preferred embodiment, two brackets 40 are provided, respectively located at both ends of the lower crossbeam. Wheels 42 are provided below each bracket 40. A seventh connecting surface 41 is provided at the top of each bracket 40, and the seventh connecting surface 41 has mounting holes 71 and a second concave portion 411. Specifically... Figure 2As shown.

[0077] The specific connection method in this embodiment is as follows:

[0078] The joint between column 30 and beam 20:

[0079] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, one end of the mounting pin 70 is inserted into the second slot 352 of the column 30, and the other end is inserted into the insertion interface 25 of the crossbeam housing 21 of the crossbeam 20.

[0080] The first connector 60 is installed at the joint between the column 30 and the beam 20. The first connecting surface 61 and the second connecting surface 62 of the first connector 60 are respectively fitted to the third side surface 33 and the fourth side surface 34 of the column. Specifically, the mounting pin 70 is also provided with mounting holes 71, which correspond to the mounting holes 71 on the first connecting surface 61. The first connecting surface 61 is fixed to the mounting pin 70 inside the third side surface 33 using screws or bolts. The mounting holes 71 on the second connecting surface 62 correspond to the mounting holes 71 on the fourth side surface 34, and the second connecting surface 62 is fixed to the fourth side surface 34 using screws or bolts.

[0081] The third connecting surface 63 of the first connecting member 60 is fitted to the upper side of the lower crossbeam housing 21 or the lower side of the upper crossbeam. Specifically, the mounting holes 71 on the third connecting surface 63 correspond to the mounting holes 71 on the upper side of the lower crossbeam housing 21 or the lower side of the upper crossbeam, and the third connecting surface 63 is fixed to the upper side of the lower crossbeam housing 21 or the lower side of the upper crossbeam using screws or bolts.

[0082] The fourth connecting surface 64 of the first connector 60 is fitted to the rear side of the crossbeam housing 21, and the first concave part 81 of the second connector 80 is pressed against the outside of the fourth connecting surface 64.

[0083] Specifically, the mounting holes 71 on the fourth connecting surface 64, the mounting holes 71 on the rear side of the beam housing 21, and the mounting holes 71 on the first concave surface 81 are positioned correspondingly, and screws or bolts are used to fix the fourth connecting surface 64 and the first concave surface 81 to the rear side of the beam housing 21. In this embodiment, the fifth connecting surface 82 is also provided with a second row of mounting holes 71. In this embodiment, the fifth connecting surface 82 is directly fixed to the rear side of the beam housing 21 by screws or bolts through the second row of mounting holes 71. The arc-shaped surface of the sixth connecting surface 83 fits against the edge of the rear side of the beam housing 21, specifically as follows: Figure 3 As shown.

[0084] It should be noted that the second connector 80 is only used to reinforce the joint between the column 30 and the upper crossbeam. The reinforcement at the joint between the column 30 and the lower crossbeam is achieved using the seventh connecting surface 41 at the top of the bracket 40. The seventh connecting surface 41 is structurally similar to the fifth connecting surface 82 of the second connector 80, and also has two rows of mounting holes 71 and a second concave surface 411 on the back.

[0085] At this point, the specific connection method is as follows: the mounting holes 71 on the fourth connecting surface 64, the mounting holes 71 on the rear side of the lower crossbeam housing 21, and the mounting holes 71 on the second concave surface 411 are positioned correspondingly, and screws or bolts are used to fix the fourth connecting surface 64 and the second concave surface 411 to the rear side of the lower crossbeam housing 21. The seventh connecting surface 41 is directly fixed to the rear side of the lower crossbeam housing 21 using screws or bolts through the second row of mounting holes 71, specifically as follows... Figure 2 and Figure 3 As shown.

[0086] Installation of fixing strip 50:

[0087] In this embodiment, the cross-section of the fixing strip 50 is angular, such as... Figure 6 As shown, the first fixing surface 51 of the fixing strip 50 is provided with a snap-fit ​​part 511, and multiple rows of grooves 321 are evenly provided on the second side surface 32 of the column 30. During installation, the first fixing surface 51 of the fixing strip 50 is attached to the second side surface 32 of the column 30, and the snap-fit ​​part 511 is engaged in the grooves 321 of the second side surface 32.

[0088] The second fixing surface 52 of the fixing strip 50 is set on the first side surface 31 of the column 30, but a display medium is also provided between the second fixing surface 52 and the first side surface 31. The purpose of the fixing strip 50 is to reinforce the installation of the display medium.

[0089] In this embodiment, the display medium is an LED holographic screen, which is composed of multiple luminous LED pixels. To avoid obstructing the LED pixels of the LED holographic screen, the second fixing surface 52 of the fixing strip 50 has holes that are uniformly distributed according to the size of the LED pixels. Since the LED pixels are arranged in rows, the holes on the second fixing surface 52 are also evenly distributed in multiple rows, and all holes are of the same size.

[0090] It should be noted that the row of holes near the first fixing surface 51 is slightly larger than the other pixel holes and is used to install screws. Its function is to fasten the fixing strip 50 to the display medium on the column 30.

[0091] In other alternative technical solutions, such as when the display medium is a poster, the second fixing surface 52 can be set as a flat surface without holes, and the form of the second fixing surface 52 can be changed according to the characteristics of the display medium. Example 2

[0092] The difference between this embodiment and embodiment 1 is that this embodiment is a display device that includes embodiment 1. Specifically, this embodiment includes a display frame and a display medium.

[0093] In this embodiment, the display device may include a single display rack or multiple display racks.

[0094] When the display device includes multiple display racks, the display device is composed of a new display rack spliced ​​together from multiple display racks and a display medium.

[0095] In this embodiment, the display medium is set on the display rack or a new display rack.

[0096] The multiple display racks are assembled as follows:

[0097] This embodiment illustrates the splicing method by splicing two display racks.

[0098] Remove the column 30 at the target splicing point of the two display frames, the first connecting piece 60 at the splicing point of the column 30 and the upper and lower crossbeams, and the bracket 40. At the same time, remove the end cap 23 at the target splicing point of the upper and lower crossbeams.

[0099] It should be noted that, in this embodiment, the fifth connecting surface 82 of the second connector 80 is provided with two rows of mounting holes 71, and each row is provided with multiple mounting holes 71. In this embodiment, each row is provided with an even number of mounting holes 71, such as 4 mounting holes 71.

[0100] When assembling two display racks, the upper crossbeams and lower crossbeams at the target splicing points are aligned. Second connectors 80 are installed at the aligned points of the two upper and two lower crossbeams. Specifically, two rows of mounting holes 71 on the fifth connecting surface 82 are evenly distributed at the splicing points of the two upper and two lower crossbeams and are secured with screws or bolts. This allows the two display racks to be assembled into a larger new display rack.

[0101] It should be noted in this embodiment that the splicing method for more than two display racks is the same as described above. However, in the splicing scheme of more than three display racks, one or more additional supports 40 can be set at the lower crossbeam to increase the support and stability. The specific details will not be elaborated in this embodiment.

[0102] The display medium in this embodiment is not limited to LED screens or holographic screens; it can also be any of other LED screens, LCD screens, projection screens, promotional posters, or other existing display media.

[0103] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
