[0024] 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. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: In the prior art, traditional advertising screens in commercial applications typically use fixed support structures. The mechanical positioning devices of these supports mainly achieve rigid connections through bolt fastening, which means that adjusting the device's position requires moving the entire screen. Therefore, operational efficiency is often low when dealing with temporary promotions, exhibition setups, and other similar scenarios. Furthermore, even when no one is present, the advertising screen continues to display content, significantly reducing advertising efficiency.

[0026] Therefore, in order to solve the above problems, simplify the assembly method of the display screen, and improve its mobility, this utility model discloses a push-pull wireless mobile advertising screen device, including a display screen and a mobile carrier, wherein the display screen is mounted on the mobile carrier. (See reference...) Figure 1 The mobile carrier includes a chassis 1; casters 2, which are located at the bottom of the chassis 1; a slot 6, which is located at the top of the chassis 1 and is adapted to connect an external display screen; and a support, which is located at the top of the chassis 1 and is distributed opposite to the slot 6; wherein, a handle 5 is provided on the side of the support away from the slot 6.

[0027] In this embodiment, when assembling the display screen, the user can insert the end of the display screen with the power interface into the slot 6, and at the same time, the support part supports the display screen against it. The inner wall of the slot 6 can limit the display screen. Through the cooperation of the slot 6 and the support part, the display screen is fixed.

[0028] Subsequently, the user can push or pull the chassis 1 using handle 5, causing the casters 2 at the bottom of the chassis 1 to roll, thereby moving the display screen. This method not only simplifies the assembly of the display screen but also improves its mobility, allowing the user to move the screen to areas with high foot traffic, aiming to improve advertising efficiency.

[0029] In a specific embodiment, the support includes a screen support frame 3 and a back plate 4. The top of the screen support frame 3 is connected to the top of the back plate 4. The screen support frame 3 is positioned close to the slot 6 and is adapted to abut against the display screen. The back plate 4 is positioned away from the slot 6 and is connected to a handle 5. Pushing or pulling the handle 5 moves the chassis 1. In use, when the display screen is inserted into the slot 6, the display screen can tilt towards the screen support frame 3 until it abuts against the screen support frame 3. At this time, the screen support frame 3 can provide abutment and support for the display screen, preventing the display screen from shaking in the slot 6 and improving the stability of the display screen. At the same time, the user can push or pull the chassis 1 through the handle 5. The casters 2 at the bottom of the chassis 1 roll due to the force, thereby achieving the purpose of moving the display screen.

[0030] Preferably, the screen support frame 3 is inclined, and there is an angle between the screen support frame 3 and the slot 6. Optionally, the angle is 75 degrees. This inclined setting helps to increase the contact area between the screen support frame 3 and the display screen, so that the display screen can fit the screen support frame 3 more closely and improve the stability of the display screen.

[0031] Meanwhile, the tilted screen support 3 also allows users to view the advertising content displayed on the screen from a more comfortable angle, enhancing the user experience.

[0032] It should be noted that caster 2 can be a swivel caster. The design of the swivel caster allows the chassis 1 to move in any direction, further improving the mobility of the display screen. In addition, caster 2 can also be equipped with a braking device to fix the chassis 1 when needed, preventing the display screen from sliding or tipping over and enhancing safety. For example, caster size 36123H-363-86A can be selected.

[0033] Furthermore, a protective layer is provided on the inner wall of the slot 6. This protective layer can be made of insulating rubber material, which can prevent leakage of electricity in the slot 6 and also play a role in shock absorption, thereby improving the safety of the display screen during use.

[0034] Example 2: Based on Example 1, in order to further improve the stability of the display screen on this device, refer to... Figure 3 The screen support frame 3 is provided with clamping mechanisms on both sides. The clamping mechanisms are adapted to clamp the display screen. The clamping mechanism includes a connecting column 10, one end of which is connected to the screen support frame 3, and the other end is provided with a fixing plate 11. The surface of the fixing plate 11 is provided with a through hole. The clamping column 12 is movably inserted into the through hole and is adapted to abut against both sides of the display screen.

[0035] The display screen is clamped by the clamping posts 12 on both sides of the screen support frame 3 to improve its stability. For example, the surfaces of the clamping posts 12 and the inner walls of the through holes are provided with matching threads. When the display screen is in contact with the screen support frame 3,

[0036] The user can manually rotate the clamping post 12, causing it to move along the threaded path on the inner wall of the through hole until it contacts both sides of the display screen, thus achieving a clamping effect. This method not only improves the stability of the display screen on the device, but also, due to the threaded connection between the clamping post 12 and the inner wall of the through hole, ensures a more uniform clamping force on the display screen, preventing it from shaking or slipping off the device, further enhancing the safety of use.

[0037] In addition, the design of the clamping post 12 makes it easy for users to adjust the position of the clamping post 12 according to the size of the display screen, so as to adapt to different sizes of display screens, thereby improving the versatility and practicality of the device.

[0038] Example 3: Based on Examples 1 and 2, in the prior art, fixed bracket structures typically use a fixed power supply to power the display screen. This method not only limits the movement range of the display screen but also makes it inconvenient to replace or maintain the power supply. To solve the above problems, refer to... Figure 1 and Figure 2 The screen support frame 3 and the back plate 4 are provided with an angle, wherein a battery compartment 8 is provided in the angle, the battery compartment 8 is suitable for placing a power source, and a power connector 7 is provided inside the slot 6, the power connector 7 is electrically connected to the power source in the battery compartment 8 through a wire. The chassis 1 is provided with a wiring channel connecting the slot 6 and the battery compartment 8, the wiring channel being adapted to the wire.

[0039] In this embodiment, the user can place the power bank into the battery compartment 8 and connect the wires. When the display screen is inserted into the slot 6, the power connector 7 will connect to the power port of the display screen, thereby transferring power from the power bank to the display screen through the wires, providing power support for the display screen. This simplifies the wiring process of the display screen and avoids the cumbersome and inconvenient nature of external power cords, making the use of the display screen more convenient.

[0040] In addition, in order to improve the stability of the power bank in the battery compartment 8, the battery compartment 8 is provided with barrier walls 9 on both sides. The two ends of the barrier walls 9 are respectively connected to the screen support frame 3 and the back plate 4. The barrier walls 9, in cooperation with the screen support frame 3 and the back plate 4, can surround the power bank in the battery compartment 8 to prevent the power bank from falling out of the battery compartment 8.

[0041] It should be noted that, in order to facilitate the access of the power bank, the height of the barrier 9 is one-third of the height of the power bank.

[0042] In summary, based on Embodiments 1 to 3, the operating steps of this push-pull wireless mobile advertising screen device are as follows:

[0043] First, check the integrity and function of each component of the device. Confirm that the chassis 1, casters 2, slots 6, screen support frame 3, back plate 4, handle 5, clamping mechanism, battery compartment 8, and power connector 7 are undamaged or deformed. Test the omnidirectional rotation flexibility of casters 2 and the effectiveness of the braking device to ensure stable and controllable movement. Check whether the threaded fit between the clamping post 12 and the through hole is smooth, whether the barrier wall 9 of the battery compartment 8 is secure, and the compatibility between the power connector 7 and the power interface of the display screen.

[0044] Next, install the power bank into the battery compartment 8, ensuring the wires are connected to the power bank. Simultaneously, utilize the angled structure between the screen support frame 3 and the back panel 4, along with the barrier wall 9, to restrain the power bank and prevent it from falling off during movement.

[0045] Next, install the display screen. Hold the end of the display screen with the power connector with both hands, align the power connector with the power plug 7 in the slot 6, and slowly insert it until it is fully engaged. At this time, the display screen will adhere to the screen support frame 3 tilted at 75 degrees due to gravity, ensuring that the screen support frame 3 is in full contact with the back of the display screen to provide stable support.

[0046] Subsequently, the display screen is secured using a clamping mechanism. The clamping posts 12 on both sides of the screen support frame 3 are rotated, moving them along the threaded path within the through holes towards the display screen until the left and right clamping posts 12 respectively contact the edges of the display screen. The self-locking characteristic of the threads applies a uniform clamping force, ensuring that the display screen remains stable and does not wobble or shift on the device.

[0047] Next, adjust the device position according to the usage scenario. The user holds handle 5 and pushes the chassis 1 to make the casters 2 roll to the target area. The 360-degree rotation characteristic of the casters allows for flexible steering. Once the device reaches the designated position, the caster brake device is activated to prevent accidental slippage.

[0048] When the battery is low during use, it can be resolved by replacing the power bank in the battery compartment 8.

[0049] Finally, after use, first turn off the power to the display screen, loosen the clamping post 12, and lift the display screen vertically upwards to disengage it from the power connector 7 in the slot 6. Move the device to the designated storage area, clean the dust from the screen surface and inside the slot 6, check the wear and tear of each component, and replace any damaged clamping post 12 or caster 2 in a timely manner to ensure reliability for the next use.
