Description

Technical Field

[0001] The present application relates to the technical field of display screens, and in particular to an electronic advertising display screen. Background Art

[0002] An electronic advertising display is a dynamic display device that utilizes LED or LCD technology and is widely used for commercial advertising and public information releases. It can update content in real time and supports multiple media formats, such as text, images, and videos. It has high brightness and clarity, ensuring clear visibility under various lighting conditions. It is suitable for a variety of scenarios, including shopping malls, transportation hubs, stadiums, and outdoor advertising, and is an important tool for modern advertising communication.

[0003] Currently, related electronic advertising display screens lack a modular and adjustable display structure, making it impossible to freely add splicing displays and group display advertising content according to advertising needs, which limits the functionality of the device.

A limiting bolt is movably installed on one end of the limiting frame, and bolt holes are provided inside the positioning block and the limiting frame, and the limiting bolt is threadedly connected to the bolt hole. A protective door is movably installed on one end of the fixed frame, and a maintenance door is movably installed on the other end of the fixed frame, and a door lock is provided on one end of the maintenance door. Limiting blocks are fixedly connected to both sides of the fixed frame, and a support seat is movably installed on the bottom of the limiting block. Both sides of the support seat are fixedly connected to the support frame, and the limiting block is engaged with the support frame. Threaded rods are movably installed on both sides of the support frame.

[0007] Preferably, a threaded hole is provided inside the limiting block, and the threaded rod is threadedly connected to the threaded hole.

[0008] Preferably, a limiting groove is provided inside the support seat, and the fixing frame is embedded in the limiting groove.

[0009] Preferably, positioning pieces are fixedly connected to both sides of the support seat, and sockets are provided inside the positioning pieces.

[0010] Preferably, both sides of the support frames at both ends of the threaded rod are fixedly connected with connecting blocks, and both sides of the connecting blocks are movably installed with limit plates.

[0011] In summary, this application has the following beneficial technical effects:

[0012] Through the setting of splicing screens, limit frames and limit bolts, staff can freely adjust the splicing screens so that the splicing screens can be spliced ​​together to display larger advertisements or separated to independently display more different advertisements, thereby achieving the required advertising display effect. The splicing screens can also be directly pulled upward and disassembled for replacement or reduction in number, thereby reducing energy consumption, meeting more usage needs, and increasing the functionality of the device. The setting of threaded rods, support frames and limit plates enables the fixed frame to be quickly disassembled and maintained as a whole without the need for tools, thereby improving maintenance efficiency.

The support frame 1 is fixed to the support frame 3. The support frame 1 is fixed to the support frame

[0020] A limiting frame 2 is fixedly connected to the inner wall of the fixed frame 1, and a splicing screen 6 is movably installed on the side close to the limiting frame 2. Positioning blocks 601 are fixedly connected to the surfaces on both sides of the splicing screen 6, and the positioning blocks 601 are engaged with the limiting frame 2. A limiting bolt 201 is movably installed at one end of the limiting frame 2, and bolt holes 202 are provided inside the positioning block 601 and the limiting frame 2, and the limiting bolt 201 is threadedly connected to the bolt hole 202. A protective door 10 is movably installed at one end of the fixed frame 1, and a maintenance door 9 is movably installed at the other end of the fixed frame 1, and a door lock 901 is provided at one end of the maintenance door 9. The staff connects the external multimedia equipment to the splicing screen 6, so that the splicing screen 6 plays electronic advertisements to complete the promotion. The protective door 10 is made of tempered glass, which can protect the splicing screen 6 without affecting its normal display. As shown, the staff can connect multiple multimedia devices with multiple splicing screens 6, and then pull the splicing screen 6 according to the advertising playback needs, so that the positioning blocks 601 on both sides of the splicing screen 6 slide inside the limit frame 2, so as to adjust the splicing screen 6, so that the splicing screens 6 can be spliced ​​together to display larger advertisements or separated and independently displayed to display more different advertisements. The staff can also directly pull the splicing screen 6 upward to disassemble it for replacement or reduce the number to reduce energy consumption. After the adjustment is completed, the limit bolt 201 is screwed into the bolt hole 202 inside the positioning block 601, which increases the friction between the positioning block 601 and the limit frame 2, thereby limiting the position of the splicing screen 6. The staff uses a special key to open the door lock 901, and then pulls open the maintenance door 9 to perform maintenance and installation operations of external multimedia devices.

[0021] Reference Figure 1A threaded hole 501 is provided inside the limit block 5, and the threaded rod 301 is threadedly connected to the threaded hole 501. The staff screws the threaded rod 301 into the threaded hole 501, which increases the friction between the limit block 5 and the support frame 3, thereby fixing the fixed frame 1 and the support seat 4.

[0022] Reference Figure 1 A limiting groove 401 is provided inside the support seat 4, and the fixing frame 1 is embedded in the limiting groove 401. When installing the fixing frame 1, the rod structure at the bottom of the fixing frame 1 is embedded in the limiting groove 401, which increases the friction between the fixing frame 1 and the support seat 4 and improves the stability of the connection between the support seat 4 and the fixing frame 1.

[0023] Reference Figure 2 , both sides of the support seat 4 are fixedly connected with positioning parts 7, and the inside of the positioning parts 7 is provided with a socket. Connect the positioning parts 7 with the external structure, and then screw the external fixing bolts between the positioning parts 7 and the external structure and pass through the sockets, so that the support seat 4 can be fixedly installed on the external structure.

[0024] Reference Figure 2 The support frames 3 at both ends of the threaded rod 301 are fixedly connected with connecting blocks 8 on both sides, and limit plates 801 are movably installed on both sides of the connecting block 8. A lock body is installed between the limit plate 801 and the connecting block 8, which can lock the limit plate 801. The limit plate 801 and the connecting block 8 are well connected through a hinge axis. Open the lock body and pull open the limit plate 801, then you can twist the threaded rod 301, close and lock the limit plate 801, and protect the threaded rod 301.

[0025] The implementation principle of an electronic advertising display screen in an embodiment of the present application is as follows: first, the support base 4 is fixedly installed at the advertising position, and then the fixing frame 1 is installed on the top of the support base 4, so that the limit block 5 is embedded in the inside of the support frame 3, and the support frame 3 and the limit block 5 are fixed by the threaded rod 301 to achieve the fixing frame 1 being fixed on the top of the support base 4. The staff loosens the threaded rod 301, and then pulls up to lift the fixing frame 1, and then the fixing frame 1 can be disassembled and maintained as a whole, and the external multimedia device is connected to the splicing screen 6, so that the splicing screen 6 plays electronic advertisements to achieve advertising. Multiple multimedia devices can be connected to multiple splicing screens 6, and then the splicing screen 6 is pulled according to the advertising playback requirements, so that the positioning blocks 601 on both sides of the splicing screen 6 slide inside the limit frame 2, so as to adjust the splicing screen 6, so that the splicing screens 6 can be spliced ​​together to display larger advertisements or separated and independently display more different advertisements.
