[0003] The display screen in the related technology usually includes a display screen and a mounting frame. Several display screens are provided, and the mounting frame is integrally formed by injection molding. Several display screens are fixedly connected to the mounting frame.

[0004] Regarding the aforementioned technologies, the mounting bracket, as the main support component of the display screen, presents significant technical challenges in its one-piece molding, resulting in high product costs. Summary of the Invention

[0005] In order to reduce the production cost of the mounting bracket while ensuring the stability of the display effect, this application provides a display device that can be used as an advertising machine, conference machine, or home television.

[0006] The technical solution provided in this application for a display device that can be used as an advertising machine, conference machine, or home television set is as follows: A display device usable as an advertising machine, conference machine, or home television includes a horizontal display screen support frame, a vertical display screen support frame, a display screen control box, and a display screen. The horizontal display screen support frame includes a first horizontal support frame and a second horizontal support frame. The first horizontal support frame is fixedly connected to the vertical display screen support frame and is arranged horizontally. The first horizontal support frame has a first mounting groove in the vertical direction, and a first U-shaped bracket is disposed within the first mounting groove. The second horizontal support frame is arranged parallel to the first horizontal support frame and is fixedly connected to the vertical display screen support frame. The second horizontal support frame is arranged horizontally and has a second mounting groove in the vertical direction, and a second U-shaped bracket is disposed within the second mounting groove. The first U-shaped bracket and the second U-shaped bracket are used together to fix the display screen. The display screen is set on one side of the horizontal display screen support frame. The display screen includes a mounting plate and a display panel. Several mounting plates are arranged in two rows. The first row of mounting plates is fixed to the first horizontal support frame by the first U-shaped bracket, and the second row of mounting plates is fixed to the second horizontal support frame by the second U-shaped bracket. A screen fixing bracket is provided on one side of the mounting plate. The side of the mounting plates away from the horizontal display screen support frame is further fixed by the screen fixing bracket. The display panel is set on the side of the mounting plate away from the screen fixing bracket. Several sets of display panels are arranged. Adjacent display panels are fixed by a screen locking component. The display screen control box is electrically connected to the display panel and is used to control the relevant information of the display panel.

[0007] By adopting the above technical solution, the vertical display screen support frame fixes the first horizontal support frame and the second horizontal support frame to a designated position. The first positioning slot facilitates the storage of the first housing U-shaped hanger, thereby fixing the first horizontal support frame through the first housing U-shaped hanger. The second positioning slot facilitates the storage of the second housing U-shaped hanger, thereby fixing the second horizontal support frame through the second housing U-shaped hanger. Thus, the display screen is fixed together by the first housing U-shaped hanger and the second housing U-shaped hanger. The array arrangement of the mounting plates facilitates the fixation of the device. The first column of mounting plates is fixed by the first housing U-shaped hanger. The second row of mounting plates is fixed by the second box U-shaped bracket and the screen fixing bracket. Thus, the mounting plates are fixed together by the first box U-shaped bracket, the second box U-shaped bracket and the screen fixing bracket, which helps to ensure the stability of the mounting plate positioning. Adjacent groups of display panels are fixed by the screen locking component, thereby realizing the self-locking between several groups of display panels, which helps to ensure the stability of the display panels and the quality of use of the display panels. The display control box controls the relevant information of the screen, which helps to reduce the production cost of the fixing frame while ensuring the stability of the display effect.

[0008] Optionally, the screen fixing bracket includes a horizontal connector and a vertical connector. The horizontal connector is arranged in a horizontal direction. One end of the horizontal connector is fixedly connected to a first column of mounting plates, and the side of the horizontal connector away from the first column of mounting plates is fixedly connected to a second column of mounting plates. The vertical connector has a first positioning groove. The horizontal connector passes through the first positioning groove and is fixedly connected to the groove wall of the first positioning groove. The display panel is fixedly connected to the vertical connector.

[0009] By adopting the above technical solution, the horizontal connector fixes the first and second column mounting plates to the designated positions, thereby further securing the mounting plates. The horizontal and vertical connectors are thus fixed together, facilitating the fixation of the vertical connector and its connection to the display panel. This, in turn, allows for the fixation of the display panel using several parts, thereby reducing the production cost of the mounting bracket while ensuring the stability of the display effect.

[0010] Optionally, the vertical connector has a screen positioning groove in the horizontal direction, and the screen positioning component is disposed in the screen positioning groove. The screen positioning component includes a first locking member, a first screen positioning member, and a second screen positioning member. The first screen positioning member has a first fixing groove, and a first rotating shaft is disposed in the first fixing groove. The first rotating shaft is rotatably connected to the groove wall of the first fixing groove. The first rotating shaft passes through the first locking member and is fixedly connected to the first locking member. The first locking member has a locking groove, and the second screen positioning member has a second mounting groove. A first positioning shaft is disposed in the second mounting groove. When the first rotating shaft is rotated to a limited position, the first positioning shaft engages with the locking groove.

[0011] By adopting the above technical solution, when the staff applies force to the first rotating shaft, the first rotating shaft rotates, thereby driving the first locking member to rotate around the first rotating shaft. When the first locking member rotates, it engages with the first positioning shaft through the locking groove on the first locking member, which helps to lock the first screen positioning member and the second screen positioning member, thereby helping to ensure the stability of the connection between the first screen positioning member and the second screen positioning member, thus helping to ensure the stability of the connection between the vertical connecting members, and helping to ensure the stability of the fixed display panel, thus helping to ensure the performance of the display panel.

[0012] Optionally, a forming groove is provided on one side of the second screen positioning component. The forming groove is D-shaped, and a snap-fit ​​piece is provided on one side of the forming groove. The snap-fit ​​piece is integrally connected to the second screen positioning component. When the first positioning shaft is snapped into the snap-fit ​​groove, the first locking member passes through the snap-fit ​​piece and snaps into the snap-fit ​​piece.

[0013] By adopting the above technical solution, the snap-fit ​​piece is set on one side of the forming groove, so that the snap-fit ​​piece deforms under force. When the first positioning shaft snaps into the positioning groove, the snap-fit ​​piece is pressed and deformed. The first locking member passes through the forming groove and snaps into the forming groove, so that the first locking member is fixed to the designated position, which helps to ensure the effectiveness and stability of the device.

[0014] Optionally, a hexagonal groove is provided on one side of the first rotating shaft.

[0015] By adopting the above technical solution, when the staff uses hexagonal bolts to pass through the hexagonal slots, the initial positioning of the first rotating shaft is achieved, which helps to ensure the effectiveness and stability of the hexagonal bolts in fixing the first rotating shaft, thus helping to ensure the stable rotation of the first locking member, and further helping to ensure the stability of the vertical connecting member connection.

[0016] Optionally, the display screen further includes a left frame, a right frame, a top frame, and a bottom frame. When the first positioning shaft is engaged with the slot, the left frame, the right frame, the top frame, and the bottom frame are respectively disposed around the display panel and used to fix the display panel. The left frame, the right frame, the top frame, and the bottom frame are all made of aluminum profiles.

[0017] By adopting the above technical solution, the top frame, bottom frame, left frame, and right frame are respectively set around the display panel and used to snap and fix the display panel. This facilitates multiple positioning and fixing of the display panel. Furthermore, the aluminum profile is lightweight, which helps ensure good connection stability while maintaining low weight. This reduces the weight of the finished product after assembly, thereby lowering the company's logistics and transportation costs. Optionally, the first U-shaped bracket includes a first vertical part, a second vertical part, a first horizontal part, and a first curved part. The first horizontal part is fixedly connected to a first horizontal support frame. The first vertical part is formed by bending the first horizontal part. The first vertical part is fixedly connected to the wall of a first mounting groove. The first curved part is formed by bending the first vertical part at the end away from the first horizontal part. The first curved part abuts against the wall of the first mounting groove. The second vertical part is formed by bending the first horizontal part at the side away from the first vertical part. The second vertical part is fixedly connected to a mounting plate.

[0018] By adopting the above technical solution, the bent part of the first hanger abuts against the wall of the first mounting groove, thereby positioning the bent part of the first hanger. This, in turn, drives the integrally formed vertical part of the first hanger to be fixedly connected to the wall of the first mounting groove, and drives the horizontal part of the first hanger to be fixedly connected to the first horizontal support frame. This achieves stable fixation of the horizontal part, the vertical part, and the bent part of the first hanger, which helps to ensure the effectiveness and stability of the connection. This, in turn, helps to ensure the stability and effectiveness of the second vertical part of the first hanger in fixing the mounting plate, and helps to reduce the production cost of the fixing frame while ensuring the stability of the display effect of the display screen.

[0019] Optionally, the second U-shaped bracket includes a second vertical part, a second vertical part, a second horizontal part, and a second curved part. The second horizontal part is parallel to the first horizontal part, and the length of the second horizontal part is less than the length of the first horizontal part. The second vertical part is formed by bending on one side of the second horizontal part and is fixedly connected to the wall of the second mounting groove. The second curved part is formed by bending on one side of the second vertical part and abuts against the bottom wall of the second mounting groove. The second vertical part is formed by bending on the side of the second horizontal part away from the second vertical part and is parallel to the first second vertical part. The length of the second vertical part is less than the length of the first second vertical part.

[0020] By adopting the above technical solution, the bent part of the second hanger abuts against the wall of the second mounting groove, thereby positioning the bent part of the second hanger. This causes the vertical part of the integrally formed first hanger to be fixedly connected to the wall of the second mounting groove, and the horizontal part of the second hanger to be fixedly connected to the second horizontal support frame. This achieves stability of the horizontal part, the vertical part, and the bent part of the second hanger. The length of the horizontal part of the second hanger helps to reduce the weight of the components while ensuring the stability of the connection, thereby reducing the weight of the component assembly and reducing the production cost of the enterprise.

[0021] Optionally, the vertical display screen support frame includes a vertical part, a first inclined part and a second inclined part. The first inclined part is formed by bending on one side of the vertical part. The included angle between the first inclined part and the vertical part is between 130 degrees and 160 degrees. The second inclined part is fixedly connected to one side of the first inclined part. The second inclined part and the first inclined part are symmetrical about the axis of the vertical part.

[0022] By adopting the above technical solution, the first inclined part and the second inclined part are stacked and arranged along the vertical axis. The arrangement between the first inclined part and the second inclined part is conducive to forming a stable triangular structure, which in turn helps to ensure the overall stability of the vertical display screen support frame, and further helps to ensure the stability and effectiveness of the overall connection of the device, and thus helps to ensure the stability of the device in use.

[0023] Optionally, both the first and second inclined portions are rotatably connected to one side of a universal swivel caster.

[0024] By adopting the above technical solution, the installation of omnidirectional optional casters helps to ensure the effectiveness of the device's movement, thereby enabling the device to move in all directions and ensuring the stability and effectiveness of the device's movement.

[0025] In summary, this application includes at least one of the following beneficial technical effects: 1. A vertical display screen support frame fixes the first and second horizontal support frames to designated positions. The first positioning slot facilitates the storage of the first housing U-shaped bracket, thereby fixing the first horizontal support frame. The second positioning slot facilitates the storage of the second housing U-shaped bracket, thereby fixing the second horizontal support frame. The first and second housing U-shaped brackets together fix the display screen. The array arrangement of the mounting plates facilitates the fixation of the device. The first column of mounting plates is fixed by the first housing U-shaped bracket, and the second column... The mounting plate is fixed by the second housing U-shaped bracket and then by the screen mounting bracket. The first housing U-shaped bracket, the second housing U-shaped bracket, and the screen mounting bracket work together to secure the mounting plate, ensuring stable positioning. Adjacent display panels are fixed by a screen locking assembly, achieving self-locking between multiple display panels. This ensures stability and quality of the display panels. Furthermore, the display control box controls relevant screen information, further reducing the production cost of the mounting bracket while maintaining stable display performance.

[0026] 2. When the operator applies force to the first rotating shaft, the first rotating shaft rotates, thereby causing the first locking member to rotate around the first rotating shaft. When the first locking member rotates, it engages with the first positioning shaft through the locking groove on the first locking member, which helps to lock the first screen positioning member and the second screen positioning member, thereby helping to ensure the stability of the connection between the first screen positioning member and the second screen positioning member, thus helping to ensure the stability of the connection between the vertical connecting members, and helping to ensure the stability of the fixed display panel, thus helping to ensure the performance of the display panel.
