Description

Technical Field

[0001] This utility model belongs to the field of display screen control frame, and in particular relates to a stage subtitle display screen control frame. Background Technology

[0002] In current stage performances, in order to provide the audience with a better viewing experience, displays are widely used on stage as an important visual presentation tool. In order to obtain better display effects, a support frame is needed to support and fix the display screen. A display screen control frame is a support device used to fix and support the display screen.

[0003] However, the inventors discovered that traditional subtitle display screen control frames mostly support the screen vertically, causing the screen to always be in a vertical position and making it impossible to adjust the display angle, resulting in a suboptimal display effect. Existing control frames are mostly based on a grid-like frame structure, and these frames are often fixed and cannot be folded, causing inconvenience for transportation and movement, and hindering performance transitions.

[0004] Furthermore, in order to reduce the space occupied by the existing control rack, the support area of ​​the control rack is relatively small. After the display screen is installed and fixed on the control rack, the center of the control rack shifts, which reduces the stability of the control rack. When subjected to external force collision or vibration, the control rack is prone to shaking or tipping over, causing display errors.

[0005] For ease of carrying, the existing control rack adopts a folding structure. However, once folded, the existing control rack cannot stand upright on its own. It needs to be placed at an angle against the wall or supported on the side by other objects, which makes the placement of the existing control rack inconvenient. Summary of the Invention

[0006] This invention solves the problem that existing display screen control frames use a grid-shaped fixed frame structure, which reduces the stability of the control frame after the display screen is fixed and supported, making it prone to shaking or tipping over. It provides a stage subtitle display screen control frame with a foldable support mechanism on the mobile carrier. The support mechanism can expand the support area of ​​the mobile carrier, thereby improving the stability of the control frame. At the same time, it can reduce the space occupied by folding, making it convenient for transfer, transportation and carrying.

[0007] This utility model provides a stage subtitle display screen control frame, including a fixed-size mobile carrier, to ensure that the control frame has a minimum and fixed standing area, so that the control frame can stand up on its own, is easy to place, and does not require external side support.

[0008] This utility model provides a stage subtitle display screen control frame. A rotatable display screen fixing mechanism is installed on the mobile carrier, allowing for convenient adjustment of the display screen's angle to adapt to different display needs and achieve the desired display effect. Furthermore, once adjusted to the correct position, it can be quickly and stably fixed.

[0009] The specific technical solution of this utility model is as follows: a stage subtitle display screen control frame, including a movable carrier with a fixed support area, a display screen fixing mechanism that is mounted on the movable carrier and can rotate relative to the movable carrier, an inclined support rod connected to the display screen fixing mechanism, and a support mechanism that is mounted on the movable carrier and can rotate relative to the movable carrier.

The display screen fixing mechanism and the support rod are triangularly supported by the movable carrier.

[0010] The mobile carrier has a fixed support area, indicating that it is a non-foldable structure. This means the mobile carrier itself can form a standing support structure, meaning that even if other components are folded, it will not affect the mobile carrier's ability to provide support. The control frame can stand upright on its own, making it easy to place without external lateral support. The display screen fixing mechanism can rotate relative to the mobile carrier, meaning that the display fixing mechanism can adjust its tilt angle. After the display screen is fixed, its display angle can be adjusted as needed for a better display effect. The support rod supports the display screen fixing mechanism, and the display screen fixing mechanism and support rod form a triangular support with the mobile carrier. The triangular structure provides better support stability. The support mechanism is hinged to the mobile carrier, allowing the support mechanism to rotate relative to the mobile carrier. The support mechanism can rotate to a support state that is flush with the mobile carrier. This allows the support area of ​​the control frame on the ground or stage to be expanded, thereby improving the standing support stability of the control frame. At the same time, when the support mechanism rotates to other angles relative to the mobile carrier, the space occupied by the control frame can be reduced, making it easier to transfer, move, and carry.

[0020] The beneficial effects of this utility model are as follows: The mobile carrier has a fixed support area, indicating that the mobile carrier is a non-foldable structure, which means that the mobile carrier itself can form a standing support structure. This means that even if other components are folded, it will not affect the mobile carrier's ability to form a support structure. The control frame can stand on its own, making it convenient to place without the need for external side support. The display screen fixing mechanism can rotate relative to the mobile carrier, meaning that the display fixing mechanism can adjust its own tilt angle.

The triangular structure has better support stability. The support mechanism is hinged to the mobile carrier, allowing the support mechanism to rotate relative to the mobile carrier. The support mechanism can rotate to a support state that is flush with the mobile carrier. This allows the support area of ​​the control frame on the ground or stage to be expanded through the support mechanism, thereby improving the standing support stability of the control frame. At the same time, when the support mechanism rotates to other angles relative to the mobile carrier, the space occupied by the control frame can be reduced, making it convenient for transfer, transportation, and carrying.
