DETAILED DESCRIPTION

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0022] Reference Figure 1-Figure 4 A portable foldable LED display includes a display screen 1. The display screen 1 is equipped with a base 2. The base 2 adopts a stable material and structural design to provide reliable support and effective side protection for the entire display screen 1.

[0023] A connecting rod 3 is fixedly connected to the base 2. A rotating base 4 is rotatably mounted on the connecting rod 3. A disassembly plate 5 is fixedly connected to the top of the base 4. A loading plate 6 is fixedly connected to the disassembly plate 5. The display 1 is fixedly mounted on the loading plate 6. The rotating design of the rotating base 4 allows the loading plate 6 to be smoothly adjusted, allowing the user to fine-tune the angle of the display 1 as needed. The disassembly plate 5 is preferably, but not limited to, bolted to the rotating base 4. This arrangement makes the overall assembly of the device convenient and easy, and also facilitates subsequent maintenance of the loading plate 6.

[0024] The base 2 is provided with an adjustment structure for adjusting the tilt angle of the loading plate 6. The setting of the adjustment structure meets the user's use angle requirements in different scenarios and improves the flexibility of the overall use of the device.

[0025] The adjustment structure includes a concave seat 7 slidably arranged on the base 2, a concave seat 2 8 fixedly connected to the bottom of the loading plate 6, an inner rod 9 fixedly connected to both the concave seat 1 7 and the concave seat 2 8, a rotating seat 2 10 is rotatably sleeved on the inner rod 9, and the same traction rod 11 is fixedly connected to the opposite side walls of the two rotating seats 2 10; through the coordinated action of the concave seat 1 7, the concave seat 2 8 and the traction rod 11, the horizontal movement of the concave seat 1 7 is converted into the rotation of the concave seat 2 8, and the concave seat 2 8 drives the loading plate 6 to adjust the angle.

[0026] The base 2 is provided with a driving member for driving the concave seat 7 to slide horizontally.

[0027] The top of the base 2 is provided with a slide groove 12 for the horizontal sliding of the concave seat 7. The setting of the slide groove 12 ensures the stability of the horizontal movement of the concave seat 7 and prevents the concave seat 7 from shaking, which affects the service life of the device.

[0028] The drive assembly comprises a pair of vertical plates 13 fixedly connected to the top of the base 2. One vertical plate 13 and the base 2 are rotatably connected by a lead screw 14, while the other vertical plate 13 is fixedly connected to the base 2 by a slide rod 15. The provision of slide rod 15 ensures stable horizontal movement of the concave seat 7 along the axis of the lead screw 14, preventing deflection caused by the threaded connection between the lead screw 14 and the transmission plate 16. Transmission plates 16 are fixedly connected to both vertical side walls of the concave seat 7. One transmission plate 16 is threadedly connected to the lead screw 14, while the other transmission plate 16 is horizontally slidably connected to the slide rod 15.

[0029] One end of the lead screw 14 extends to the outside of the base 2 and is fixedly connected with a rotary block 17. The rotary block 17 is arranged in a hexagonal shape, which is in line with ergonomic design and reflects the humanization of the device.

[0030] A groove 19 is defined on one side of the loading plate 6 near the display screen 1. A fastening bolt 18 is threadedly connected to the groove 19 and the second concave seat 8. The provision of fastening bolt 18 allows the loading plate 6 to be removed from the second concave seat 8 for replacement, thereby accommodating the subsequent installation of display screens 1 of various sizes. The provision of groove 19 provides space for fastening bolt 18, preventing it from obstructing the installation of the display screen 1.

[0031] The functional principle of this utility model can be explained through the following operation modes:

[0032] First, the display screen 1 is fixed on the carrier plate 6. The display screen 1 is the core component of the entire device and is used to display information.

[0033] The tilt angle of the loading plate 6 is adjusted by adjusting the structure. This step ensures that the display screen 1 can be adjusted according to the user's viewing needs, providing an optimal viewing experience. Specifically, the operation is as follows: rotating the rotary block 17 drives the lead screw 14, which drives the transmission plate 16 to move horizontally. The transmission plate 16 drives the concave seat 7 to slide horizontally within the slide groove 12. The traction rod 11 and the inner rod 9 work together to rotate the loading plate 6, achieving the adjustment of its tilt angle.

[0034] Folding and carrying: When the device needs to be moved or carried, the rotary block 17 is rotated in the reverse direction, and the rotary block 17 drives the lead screw 14 to rotate. After the reverse operation, the loading plate 6 and the display screen 1 are both at the 0° level, so that the entire device is in a folded state. This design makes the device more portable and convenient for storage and transportation.

[0035] The design of this portable foldable LED display device fully considers the user's portability, viewing experience and stability requirements. Through a series of adjustment and fixing mechanisms, the display can provide a stable and comfortable viewing experience in various environments.

[0036] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
