[0039] The principle and structure of the present invention will be described in detail below with reference to the drawings and embodiments.

[0040] Such as Figures 1 to 3As shown in the figure, the present invention provides a portable display device, which includes at least one display box. Each display box includes: a box body 3, a screen assembly 1, a control box 8, and a support assembly 2. The support assembly 2 can be folded and stored in the box body 3 or unfolded and installed on the box body 3, and can form a support body with the box body to support the screen assembly 1. The screen assembly 1 is composed of multiple sub-screens 11 arranged in an array after being unfolded. Two adjacent or longitudinally adjacent sub-screens 11 are connected by a hinge, so that the screen assembly 1 can be folded or unfolded. The folded screen assembly 1 can be directly placed in the box body 3. After the box body 3 is placed horizontally, the support assembly is installed on the box body 3, and the unfolded screen assembly 1 can be installed on the support assembly 2 for display. In a specific embodiment, two screen assemblies 1 and two support assemblies 2 are placed in each box body 3 in a one-to-one correspondence. When in use, the two support assemblies in a single box body are installed side by side, the two screen assemblies 1 are installed on the two support assemblies, and a display unit is formed through a connection assembly; when a larger display surface is needed, multiple box bodies 3 are arranged side by side and close to each other, and the adjacent support assemblies 2 and screen assemblies 1 are connected by a connection assembly to form a display surface with a larger display area. By using the box body as the main carrier, the transportation is more convenient. At the same time, after unfolding, they can be jointly assembled into the same large screen, greatly increasing the display surface, so that more people can view the specific picture when demonstrating relevant information at a temporarily set-up site.

[0041] The present invention further includes a screen protection box 4. After the screen assembly 1 is folded, it is placed in the screen protection box 4 to prevent the screen from directly contacting other components in the box body 3, thereby protecting the screen. And the screen protection box 4 is placed in the box body and fixed by the support assembly 2. In a specific embodiment, there are 4 sub-screens 11 in each row of each screen assembly 1, and 8 sub-screens 11 in each column. Hinges can be provided only between two adjacent sub-screens in each column.

[0042] As Figures 4 to 8As shown, the box body 3 includes a main body 31 with an opening on one side and a box cover 32 covering the opening. The support assembly 2 specifically includes: a telescopic rod 22, a cross beam 23, a steel wire 27 and a telescopic rod support frame. One end of the telescopic rod 22 is inserted into the inner bottom surface of the main body. There is an insertion seat 311 corresponding to the telescopic rod on the main body, and it is perpendicular to the inner bottom surface of the main body 31. The other end of the telescopic rod 22 is provided with a cross beam 23 perpendicular to the telescopic rod 22. The cross beam 23 can be hooked and fixed to the screen assembly 1, and is abutted against the back of a row of horizontally arranged sub-screens 11 at the upper edge of the screen assembly. Both ends of the cross beam 23 are connected between two adjacent sub-screens 11 of this row of sub-screens 11, so that the horizontal expansion of the screen assembly 1 remains straight and prevents an included angle from appearing between two adjacent sub-screens 11. The telescopic rod support frame specifically includes: a collar 24 and a plurality of collar support rods 25. The collar 24 is sleeved on the telescopic rod 22 and can slide along the telescopic rod 22. One end of the collar support rod 25 is hinged to the collar 24, and the other end is inserted into a groove 312 provided on the inner bottom surface of the main body 31 corresponding to the collar support rod 25, so that the collar support rod 25 can be kept stable without deviation. Among them, the telescopic rod can be telescopically adjusted in length, so that the height of the cross beam connecting the screen assembly can be adjusted, and it is used to fix a larger area screen assembly.

[0043] As Figures 9 to 11 shown, in a specific embodiment, after the screen assembly 1 is unfolded, a hanging strip 28 with hooks 281 is installed around the upper edge of its back. The hooks 281 can be hooked on the cross beam 23, and then the screen assembly is fixed by screws passing through the cross beam and the hanging strip, which is convenient for installation and prevents the screen from being damaged.

[0044] The connecting components specifically include: multiple first connecting pieces 71 that connect two adjacent supporting components 2, and multiple second connecting pieces 72 that connect two adjacent unfolded screen components 1. Among them, the first connecting pieces 71 connect to the ends of the crossbeams 23 of two adjacent supporting components 2. Both ends of each crossbeam 23 are connected to positions between two adjacent sub-screens 11. By connecting the first connecting pieces 71 through the crossbeams 23, the sub-screens in a row at the upper edge of multiple display boxes arranged side by side are horizontally connected, so that each row of sub-screens in the entire display surface formed by the screen components of multiple display boxes remains stable and straight. The second connecting pieces 72 are arranged longitudinally and are connected between two adjacent screen components 1, and are located on two adjacent columns of sub-screens on the back of two adjacent screen components. Every two adjacent sub-screens 11 in a column of sub-screens 11 are connected by one second connecting piece 72, so that each column of sub-screens in the entire display surface formed by the screen components of multiple display boxes remains stable and straight. In specific connection, a connecting buckle is provided on the back of each sub-screen 11 in a column of sub-screens at the edge. Four connecting holes corresponding to the connecting buckles are provided on each second connecting piece 72. The second connecting piece 72 is sleeved on the connecting buckle and slides along the direction of the shrinking of the connecting hole, so that the second connecting piece 72 tightly adheres to the backs of several sub-screens 11 at the same time. Each second connecting piece 72 connects four adjacent sub-screens at the same time. Every two sub-screens located in the same column are on one screen component, so that two adjacent screen components are completely connected together.

[0045] As Figures 12 to 14 As shown in the figure, in the present invention, multiple pulleys 61 and support feet 62 are provided on the side of the main body facing away from the opening. Among them, there are 2 pulleys 61, which are respectively arranged near two diagonals of the bottom surface of the main body, and a switchable braking device is provided on the pulley to lock the pulley to prevent rotation. There are 2 support feet 62 in total. One end of the support foot 62 is hinged and installed on the outer wall of the main body, and the other end is provided with a caster, which can be rotated to the two sides of the main body 31 respectively and then extended out of the main body 31 to support the main body 31, so that the main body 31 is horizontally placed and remains stable as the base of the supporting component 2, thereby ensuring the stability of the entire device. A notch concave corresponding to the pulley 61 is provided on the box cover 32, which can ensure the stability of multiple stacked boxes 3 during transportation and is convenient for transporting the boxes.

[0046] As Figure 15 As shown in the figure, one end of the steel wire 27 is detachably connected to one end of the crossbeam 23 on which the telescopic rod 22 is installed, and the other end is connected to the support foot 62 after the main body is rotated and opened, forming a stable triangle to improve stability.

[0047] As Figure 16As shown, in specific use, multiple display boxes are horizontally placed side by side. At the same time, the support feet provided on the bottom surface of the main body are rotated outwards to support the main body. Two telescopic rods are vertically inserted into the insertion positions on the bottom surface of the main body. A collar is sleeved on the telescopic rod and supported by the collar support rod. The screen assembly is unfolded, and a screen edge is installed on the horizontal upper edge of its back. The screen assembly is fixed by connecting the screen edge and the cross beam on the telescopic rod through buckling and screws. Then, adjacent two cross beams are connected by the first connecting piece to integrate the support components, and adjacent two screen components are connected by the second connecting piece to stably splice multiple screen components while ensuring flatness, providing a good display picture.

[0048] As Figure 17 shown, the present invention further includes a platform support rod 33, and each box cover 32 corresponds to two platform support rods 33. The support foot 62 is provided with a through hole through which the platform support rod 33 passes. The other end of the platform support rod is connected to the inner side of the box cover 32 and can be hinged to the box cover 32 for convenient storage. When in use, the platform support rod 33 passes through the through hole of the support foot to support the box cover 32 to form a platform. One side of the box cover 32 is supported by two platform support rods 33, and the other side is directly placed on the collar support rod 25. Moreover, the height of the box cover 32 is flush with the bottom of the unfolded screen assembly, so that the unfolded screen assembly can just be placed on the box cover 32.

[0049] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
