[0035] 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. The following description of at least one exemplary embodiment is actually illustrative only and is in no way intended to limit the present utility model or its application or use. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.

[0036] In this embodiment, as Figures 1 to 4As shown, the display device includes: a bracket, a display screen 90, a first hook 10, a second hook 20, and a first adjusting member. The bracket includes a support leg 81 and a crossbar 82 connected to the support leg 81. The display screen 90 includes a housing and a display module disposed on the front side of the housing. The housing includes a frame 91 and a longitudinal beam 92 disposed within the frame 91. The longitudinal beam 92 divides the internal space of the frame 91 into multiple windows 93. The first hook 10 is connected to the longitudinal beam 92 and hooked onto the crossbar 82. The second hook 20 is connected to the frame 91 and hooked onto the crossbar 82. The second hook 20 is provided with a first mounting hole 231. The first adjusting member is movably inserted into the first mounting hole 231 and abuts against the surface of the crossbar 82 to adjust the distance between the first hook 10 and the crossbar 82.

[0037] In this way, the longitudinal beam 92 improves the structural strength of the cabinet, thereby reducing the deformation of the display screen 90 due to gravity when it is hung on the crossbar 82, improving the flatness of the front surface of the display screen 90, and thus improving the display effect. Furthermore, by setting the first hook 10 on the longitudinal beam 92, the middle of the rear side of the display screen 90 can be better connected to the crossbar 82, making the connection between the display screen 90 and the bracket more stable and reliable. The second hook 20 allows the rear end of the display screen 90 to be better connected to the crossbar 82, reducing the possibility of excessive distance between the edge of the display screen 90 and the bracket, thereby improving the flatness of the display surface. Moreover, the first adjusting member allows adjustment of the distance between the first hook 10 and the crossbar 82, thereby adjusting the distance between the frame 91 connected to the first hook 10 and the crossbar 82, making the distance between the frame 91 and the crossbar 82 closer to the distance between the longitudinal beam 92 and the crossbar 82, thus improving the flatness of the front surface of the display screen 90, and further improving the flatness of the display surface and the display effect. Therefore, the technical solution of this embodiment effectively solves the problem in the related art that the display screen is hung on the bracket by hooks, which easily makes the display surface uneven.

[0038] By applying the above embodiments, the first hook 10 and the second hook 20 enable a single bracket to quickly adapt to various models of boxes, achieving broad compatibility and convenient mobile installation.

[0039] In this embodiment, the display device further includes casters mounted on the support leg 81 to facilitate movement of the display device. The display screen 90 also includes a rear cover 94 covering the window 93. There is one longitudinal beam 92 and two windows 93, which are located on opposite sides of the longitudinal beam 92.

[0040] It should be noted that multiple windows 93 refers to two windows 93, three windows 93, four windows 93, or more than four windows 93. In other embodiments, when there are two longitudinal beams 92, the two longitudinal beams 92 divide the internal space of the frame 91 into three windows 93.

[0041] like Figure 2 and Figure 4 As shown, the second hook 20 includes a first plate segment 21, a second plate segment 22, and a third plate segment 23 connected in sequence. The first plate segment 21 is connected to the frame 91, the second plate segment 22 overlaps the top of the crossbar 82, and the third plate segment 23 extends downward. A first mounting hole 231 is provided on the third plate segment 23, and a first adjusting member abuts against the rear surface of the crossbar 82 to adjust the distance between the first hook 10 and the crossbar 82 in the front-rear direction of the housing. This arrangement of the second hook 20 allows for close contact between the second hook 20 and the rear surface of the crossbar 82, improving the reliability of the connection between the second hook 20 and the crossbar 82. The first mounting hole 231 can cooperate with the first adjusting member to adjust the distance between the first hook 10 and the crossbar 82 in the front-rear direction of the housing. This arrangement allows for more precise adjustment of the distance between the display screen 90 and the bracket, effectively solving the problem of slight unevenness of the display surface caused by installation errors.

[0042] In this embodiment, the crossbar 82 includes a first plane and a second plane arranged opposite to each other in the front-back direction, and a third plane and a fourth plane arranged at intervals in the up-down direction. The third plane and the fourth plane are both connected between the first plane and the second plane.

[0043] like Figure 2 and Figure 4 As shown, the second plate segment 22 is provided with a second mounting hole 221. The display device also includes a second adjusting member, which is movably inserted into the second mounting hole 221. The second adjusting member abuts against the top surface of the crossbar 82 to adjust the distance between the first hook 10 and the crossbar 82 in the vertical direction of the housing. The cooperation between the second mounting hole 221 on the second plate segment 22 and the second adjusting member makes it possible to adjust the height of the display screen 90. This design makes it easier to fine-tune the display screen 90 in the vertical direction, thereby facilitating the adjustment of the level of each display screen 90 and the alignment of multiple display screens 90 in the display device in the horizontal direction. Furthermore, by setting the second adjusting member on the second hook 20 connected to the frame 91, the height of the edge of the display screen 90 can be adjusted, thereby improving the adjustment efficiency of the display screen 90. Through fine-tuning the vertical direction of the display screen 90, the display effect of the display device is further optimized.

[0044] like Figure 2 and Figure 3As shown, the first hook 10 includes a fourth plate segment 11, a fifth plate segment 12, and a sixth plate segment 13 connected in sequence. The fourth plate segment 11 is connected to the longitudinal beam 92, the fifth plate segment 12 overlaps above the crossbar 82, and the sixth plate segment 13 extends downward. The above-mentioned arrangement of the first hook 10 allows the first hook 10 to make close contact with the rear surface of the crossbar 82, improving the reliability of the connection between the first hook 10 and the crossbar 82.

[0045] Preferably, the first hook 10 is a one-piece molded structure. The second hook 20 is a one-piece molded structure.

[0046] like Figure 2 and Figure 3 As shown, the first hook 10 also includes a flange 14 connected to the fourth plate segment 11 or the fifth plate segment 12, with the flange 14 located between the fourth plate segment 11 and the crossbar 82. The flange 14 improves the structural strength of the first hook 10. Furthermore, placing the flange 14 between the fourth plate segment 11 and the crossbar 82 reduces the swaying of the first hook 10 when it is attached to the crossbar 82, reduces the displacement of the display screen 90 in the front-to-back direction during installation, and enhances the stability of the attachment. The fifth plate segment 12 is provided with a third mounting hole 121, and the display device also includes a third adjusting member, which is movably inserted into the third mounting hole 121. The third adjusting member abuts against the top surface of the crossbar 82 to adjust the distance between the first hook 10 and the crossbar 82 in the vertical direction of the housing. The third mounting hole 121, in conjunction with the third adjusting member, allows the first hook 10 to be adjusted in the vertical direction relative to the crossbar 82, thereby enabling the middle part of the display screen 90 to be adjusted in the vertical direction relative to the crossbar 82. This facilitates the adjustment of the level of each display screen 90 and also facilitates the horizontal alignment of multiple display screens 90 in the display device.

[0047] In other embodiments, the first hook 10 further includes a flange 14 connected to the fourth plate segment 11 or the fifth plate segment 12, the flange 14 being located between the fourth plate segment 11 and the crossbar 82. Alternatively, the fifth plate segment 12 is provided with a third mounting hole 121, and the display device further includes a third adjusting member, the third adjusting member being movably inserted into the third mounting hole 121, the third adjusting member abutting against the top surface of the crossbar 82 to adjust the distance between the first hook 10 and the crossbar 82 in the vertical direction of the housing.

[0048] like Figure 2 and Figure 3As shown, there are at least two display screens 90. Two adjacent display screens 90 are spliced ​​together along the vertical direction of one of the display screens 90 to form a display screen group. The fourth plate segment 11 is connected to the two longitudinal beams 92 of the display screens 90 in the display screen group. When there are at least two display screens 90 spliced ​​together along the vertical direction, the fourth plate segment 11 can connect the longitudinal beams 92 of the two display screens 90, thereby hanging the two display screens 90 on the crossbar 82 through the first hook 10, reducing the installation and use of additional structures, and improving the splicing efficiency and hanging efficiency of the display screens 90.

[0049] like Figure 1 and Figure 5 As shown, the display device also includes a system host 71 and a host connector. The system host 71 is electrically connected to the display screen 90, and the host connector is attached to the bezel 91. The system host 71 is connected to the host connector. The system host 71 is directly connected to the display screen 90 via the host connector, which not only simplifies the installation process but also provides a more convenient storage method, facilitating the movement and assembly of the all-in-one display device. The design of the host connector allows the system host 71 to be quickly positioned and installed behind the display screen 90, reducing the need for additional cables and brackets, improving the overall integration of the display device, and also facilitating the maintenance and updates of the system host 71.

[0050] like Figure 1 and Figure 5 As shown, the host connector includes a first connector 40, which includes a first connecting plate 41 and a first support plate 42 connected to the first connecting plate 41. The first end of the first connecting plate 41 is connected to the frame 91, and the second end of the first connecting plate 41 is connected to the longitudinal beam 92. The system host 71 is mounted on the top surface of the first support plate 42. The use of the first connector 40, especially the top surface of the first support plate 42 supporting the system host 71, improves the ease of installation. The connection between the first end of the first connecting plate 41 and the frame 91, and the connection between the second end of the first connecting plate 41 and the longitudinal beam 92, makes the connection between the first connecting plate 41 and the housing more convenient and reliable.

[0051] like Figure 5 As shown, the display device also includes a first fastener. A first elongated hole 421 is provided on the first support plate 42, and the first fastener passes through the first elongated hole 421 to connect with the system host 71. The first fastener passing through the first elongated hole 421 and connecting with the system host 71 allows the connection position between the system host 71 and the first support plate 42 to be finely adjusted as needed, improving the applicability and flexibility of the first connector 40.

[0052] like Figure 1 and Figure 5As shown, the host connector includes a second connector 50, which includes a second connecting plate 51 and a third connecting plate 52 connected to the second connecting plate 51.
