This invention, through the design of the lower connecting arm, upper connecting arm, connecting frame, and the storage slot on the back of the lower connecting arm, achieves the effect of the upper connecting arm being completely folded and hidden within the storage slot. This allows the entire display screen support structure to significantly reduce its volume when not in use, effectively solving the core problems of existing mobile stand-type display screen structures being fixed and occupying too much space, and significantly improving the product's portability and space efficiency for storage and transportation.

Description

Technical Field

[0001] This utility model belongs to the field of display screen technology, and more specifically, it relates to a foldable display screen. Background Technology

[0002] Display screens are important devices used to present various types of information such as text, images, and videos. They are widely used in commercial media, cultural performances, sports venues, information dissemination, news releases, and securities trading to meet diverse environmental needs.

[0003] Currently, there are two main methods for installing displays: one is to fix them to the wall using a bracket, which offers high stability but a fixed position; the other is to use a movable stand to stand them on the ground, offering greater flexibility. However, existing displays using movable stands typically have a fixed stand structure, making them difficult to fold, resulting in excessive space requirements for carrying and use, and insufficient convenience, thus presenting certain limitations. Therefore, in view of this, this study aims to research and improve upon the existing structure and its shortcomings, providing a foldable display screen to achieve greater practical value.

[0028] Example:

[0029] As attached Figure 1 To be continued Figure 8 As shown:

[0030] This utility model provides a foldable display screen, including a movable base 1 and a display screen 4. A connecting seat is provided on one side of the top of the movable base 1, and the connecting seat is connected to a lower connecting arm 2 via a damping pivot. The top of the lower connecting arm 2 is connected to an upper connecting arm 3 via a damping pivot, and the top of the upper connecting arm 3 is connected to a connecting frame 8 via a damping pivot. The connecting frame 8 is rotatably connected to a fixing member 6, and the fixing member 6 is fixedly connected to the back of the display screen 4 by fasteners. A storage slot is provided on the back of the lower connecting arm 2, and the upper connecting arm 3 can be completely folded and hidden in the storage slot. Through the cooperation of three sets of damping pivots and the storage slot, the upper connecting arm 3 and the display screen 4 can be completely folded and stored, greatly reducing the transportation volume and solving the core problems of poor portability and large space occupation caused by the non-foldable nature of existing brackets.

[0031] The center of the fixing member 6 is rotatably connected to the center of the connecting frame 8 via a shaft; a limiting plate 7 is installed between the fixing member 6 and the connecting frame 8, and the limiting plate 7 is fixedly connected to the fixing member 6; a limiting flange is provided on the outer side of the lower half of the limiting plate 7; the limiting plate 7 and the fixing member 6 are rigidly connected to form a rotating base, and the limiting flange acts as a physical stop to precisely constrain the horizontal rotation angle of the display screen 4, prevent cable entanglement, and avoid structural damage caused by excessive rotation.

[0032] The top of the connecting frame 8 is provided with a limiting block, and the limiting block is slidably connected to the outer side of the upper half of the limiting disk 7; the limiting block and the limiting disk 7 slide together to form a dynamic limiting track, which provides real-time mechanical guidance during rotation, enhances the stability of the angle adjustment of the display screen 4, and under the action of the limiting flange, the rotation angle of the display screen 4 can be limited to the range of ±90°.

[0033] The upper and lower ends of the connecting frame 8 are slidably connected to the upper cover 10 and the lower cover 9, respectively, and the upper cover 10 and the lower cover 9 are engaged. One side of the upper cover 10 and the lower cover 9 are provided with a semi-circular disk, and the two sets of semi-circular disks are the same size. The sliding cover can be quickly disassembled and assembled by engaging. The spliced ​​semi-circular disks form a complete protective ring, providing full protection for the rotating parts, preventing dust from entering, and facilitating disassembly during maintenance.

[0034] The outer side cover of the fastener 6 is provided with a shielding plate 11. The shielding plate 11 has a connecting round opening at its center, and the size of the connecting round opening is the same as the size of the two sets of semi-circular plates after splicing. The connecting round opening of the shielding plate 11 is precisely matched with the semi-circular plate of the cover, realizing a seamless connection between the rotating mechanism and the cover, improving the overall dustproof performance, and is especially suitable for outdoor scenes.

[0035] The upper and lower ends of the upper connecting arm 3 and the bottom end of the lower connecting arm 2 are all equipped with protective covers for covering the damping shaft. Protective covers are installed at all key points of the damping shaft to eliminate the risk of foreign objects getting stuck in the shaft gaps, extend the service life of the shaft, and ensure the long-term reliability of the folding action.

[0036] The protective cover consists of a cover body 12 and a cover body 2 13. Both cover body 12 and cover body 2 13 have a locking block at one end inside. The upper and lower ends of the upper connecting arm 3 and the bottom end of the lower connecting arm 2 are provided with locking grooves that connect to the locking blocks. The locking grooves and locking blocks allow for quick and accurate positioning and installation of cover body 12 and cover body 2 13, facilitating their fastening. Cover body 12 has a fastening groove at one end inside, and cover body 2 13 has a corresponding fastener inside, enabling tool-free installation of cover body 12 and cover body 2 13, providing high assembly convenience.

[0037] The bottom of the mobile base 1 is equipped with multiple sets of casters 5, and all casters 5 are nylon casters with brake components. The nylon casters provide low-noise and smooth movement, and the brake components ensure the instantaneous parking stability of the display screen on the ground, making it suitable for smooth ground environments such as shopping malls and exhibition halls.

[0038] Finally, it should be noted that the damping shaft used in this application is a device that exists in the prior art. Its specific composition, principle and selection in actual use are clear to those skilled in the art and are common knowledge in the field, so it will not be described in detail here.

[0039] The embodiments of this utility model are given for illustrative and descriptive purposes only, and are not intended to be exhaustive or to limit the utility model to the forms disclosed. Many modifications and variations will be apparent to those skilled in the art. The embodiments were chosen and described in order to better illustrate the principles and practical applications of this utility model, and to enable those skilled in the art to understand this utility model and design various embodiments with various modifications suitable for a particular purpose.
