[0002] Currently, curved LED displays are generally constructed by splicing together multiple small, straight LED screens. This is primarily achieved by connecting the various small display frames behind the LED panels using curved interlocking mechanisms. However, the individual frames and LED panels themselves are still straight, resulting in a rigid curved screen with noticeable seams. Furthermore, some small screens with significant curvature cannot be directly spliced, posing challenges to LED display installation. Therefore, a curved single-unit display frame and LED display solution are urgently needed. Utility Model Content

[0003] In view of the above problems, embodiments of the present invention are proposed to provide a display frame and an LED display screen that solve the above problems or at least partially solve the above problems.

[0012] Furthermore, the two ends of the two sliding rods are provided with a second arc-shaped sliding groove. The second arc-shaped sliding groove is arranged adjacent to the first arc-shaped sliding groove. The curvature of the second arc-shaped sliding groove is different from that of the first arc-shaped sliding groove. The second arc-shaped sliding groove is provided with a positioning pin that can connect the connecting part.

[0013] Furthermore, the two second arc-shaped slides are respectively provided on both sides of the first arc-shaped slide, and the arc of the first arc-shaped slide and the arc of the two second arc-shaped slides are three arc values ​​of different sizes.

[0014] Furthermore, each of the two sliding rods has a receiving groove at its two ends to accommodate the fastener and the end of the positioning pin, and both the second arc-shaped sliding groove and the first arc-shaped sliding groove are located within the receiving groove.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0027] Please refer to Figure 1 This is an exploded three-dimensional structural diagram of a display screen frame provided by an embodiment of the present utility model. The display screen frame includes two fixed support rods 10, two sliding rods 20, and two first elastic plates 201.

[0028] Please combine Figures 2-4 The two fixed support rods 10 are arranged opposite each other and separated by a gap. The ends of the two fixed support rods 10 are respectively provided with connecting parts 110 extending towards each other. The two sliding rods 20 are respectively connected at both ends to the two connecting parts 110 of the two fixed support rods 10 to form a closed quadrilateral frame. The two ends of the two sliding rods 20 are respectively provided with first arc-shaped sliding grooves 210. Fasteners 30 pass through the first arc-shaped sliding grooves 210 and are connected to the connecting parts 110. The fasteners 30 can reciprocate within the first arc-shaped sliding grooves 210. One side of the two sliding rods 20 along its length direction is an arc-shaped structure 220 that is high in the middle and low at both ends. The two first elastic plates 201 are respectively provided above the arc-shaped structure 220 of the two sliding rods 20, and their ends are respectively connected to the two fixed support rods 10.

[0029] Specifically, the two fixed support rods 10 are arranged opposite each other with a gap between them. Each fixed support rod 10 has a connecting portion 110 extending towards the other fixed support rod 10 at both ends. The connecting portion 110 and the middle part of the fixed support rod 10 are generally integrally connected, but can also be detachably connected by screws, thus forming a U-shaped structure with opposite openings between the two fixed support rods 10. Two sliding rods 20 are respectively located between the two fixed support rods 10, and each sliding rod 20 has its two ends connected to the two fixed support rods respectively. The connecting portions 10 are located on the same side, thereby connecting the two fixed bracket rods 10 and the two sliding rods 20 end to end, forming a closed quadrilateral frame, which can be rectangular or square; each sliding rod 20 has a first arc-shaped groove 210 at both ends, the two first arc-shaped grooves 210 on the same sliding rod 20 have the same curvature and are axially symmetrical about the central vertical axis of the sliding rod 20; each sliding rod 20 has a fastener 30 at both ends, the fastener 30 passing through... The first arc-shaped groove 210 is connected to the connecting part 110 so that the sliding rod 20 and the connecting part 110 are directly connected; each sliding rod 20 has an arc-shaped structure 220 along its length direction, which refers to the side facing the mounting surface of the display screen frame, that is, the side of the sliding rod 20 facing the mounting surface of the display screen frame is not straight, but has a certain curvature. The two first elastic pieces 201 are respectively perpendicular to the middle part of the two fixed bracket rods 10, and the two ends of the two first elastic pieces 201 are perpendicular to the middle part of the two fixed bracket rods 10. The two first elastic pieces 201 are located above the connecting part 110, so that the two first elastic pieces 201 are located above the arc-shaped structure 220 of the two sliding rods 20. At the same time, the two ends of the two first elastic pieces 201 are respectively connected to the two fixed bracket rods 10. The specific connection method includes, but is not limited to, screw connection. The two first elastic pieces 201 have a certain elasticity and can change with the curvature of the arc-shaped structure 220. The two first elastic pieces 201 and the middle part of the two fixed bracket rods 10 together constitute the mounting surface of the LED display screen.The fastener 30 can reciprocate within the first arc-shaped groove 210. If a certain pressure is applied to one end of the sliding rod 20, the fastener 30 will move relative to the sliding rod 20 within the first arc-shaped groove 210. Here, the fastener 30 and the connecting part 110 are actually stationary, while the sliding rod 20 is movable. Specifically, the two ends of the sliding rod 20 can rotate relative to its central axis. This allows different positions of the arc-shaped structure 220 to abut against the first elastic sheet 201 above it, thereby giving it different curvatures. This results in different curvatures on the mounting surface of the display frame, thus enabling the individual LED display to have corresponding curvatures and expanding the applications of the LED display.

[0030] Furthermore, in other preferred embodiments of the present invention, the display screen frame further includes a plurality of second elastic pieces 40, which are spaced apart between the two first elastic pieces 201 and connected at both ends to the two fixed support rods 10 above the arc-shaped structure 220.

[0031] Specifically, the plurality of second elastic plates 40 span between the two fixed support rods 10 and are equally spaced between the two first elastic plates 201. Both ends of the plurality of second elastic plates 40 are detachably connected to the two fixed support rods 10 above the arc-shaped structure 220 via screws or other means. Here, the second elastic plates 40, like the first elastic plates 201, possess a certain degree of elastic bending performance. When the two sliding rods 20 rotate, they can follow the curvature deformation of the mounting surface of the display frame, thereby providing a larger mounting surface for the LED panel above the display frame and helping to improve the reliability of the connection between the LED panel and the display frame.

[0032] Furthermore, in other preferred embodiments of the present invention, the two first elastic sheets 201 and the second elastic sheet 40 comprise manganese steel spring sheets.

[0033] Here, the manganese steel spring not only has excellent bending deformation performance, but also high strength. While ensuring the installation of the curved screen, it can also improve the installation strength of the display screen frame.

[0034] Furthermore, in other preferred embodiments of the present invention, the display screen frame further includes two pressure plates 50, which are respectively disposed above the two fixed support rods 10 to press the two ends of the two first elastic pieces 201 and the plurality of second elastic pieces 40 onto the two fixed support rods 10.

[0035] Specifically, the two pressure plates 50 are respectively disposed above the main body between the two connecting parts 110 of the two fixed bracket rods 10. The specific connection method includes, but is not limited to, fixing by screws. In this way, the two ends of the two first elastic pieces 201 and the plurality of second elastic pieces 40 are pressed and connected to the two fixed bracket rods 10 by the pressure plates 50.

[0036] Furthermore, in other preferred embodiments of the present invention, the two ends of the two sliding rods 20 are also provided with a second arc-shaped sliding groove 230, the second arc-shaped sliding groove 230 is arranged adjacent to the first arc-shaped sliding groove 210, the curvature of the second arc-shaped sliding groove 230 is different from the curvature of the first arc-shaped sliding groove 210, and a positioning pin 60 capable of connecting the connecting part 110 is provided in the second arc-shaped sliding groove 230.

[0037] Specifically, each of the sliding rods 20 has two arc-shaped grooves at its two ends, namely the second arc-shaped groove 230 and the first arc-shaped groove 210. Just as the two first arc-shaped grooves 210 on the same sliding rod 20 have the same curvature and are axially symmetrical about the central vertical axis of the sliding rod 20, the two second arc-shaped grooves 230 on the same sliding rod 20 have the same curvature and are axially symmetrical about the central vertical axis of the sliding rod 20, and the curvature of the second arc-shaped groove 230 is different from that of the first arc-shaped groove 210. In use, either the second arc-shaped groove 230 or the first arc-shaped groove 210 can be selected as the connecting groove for connecting with the first connecting part 110, while the other arc-shaped groove can serve as a positioning groove. The positioning pin 60 can be installed in the positioning groove. For example, in this embodiment, the first arc-shaped groove 210 serves as the connecting groove, and the fastener 30 is installed inside it; while the second arc-shaped groove 230 serves as the positioning groove, and the positioning pin 60 is installed inside it.

[0038] Here, since the second arc-shaped groove 230 and the first arc-shaped groove 210 are arc-shaped grooves with different curvatures, when one of the arc-shaped grooves is selected as the connecting groove, the arc-shaped structure 220 can present mounting surfaces with different curvatures, so that the display frame presents multiple different mounting curvatures, thereby improving the application range of the display frame.

[0039] Furthermore, two second arc-shaped grooves 230 are respectively provided on both sides of the first arc-shaped groove 210, and the arc of the first arc-shaped groove 210 and the arc of the two second arc-shaped grooves 230 are three arc values ​​of different sizes.

[0040] Specifically, each of the sliding rods 20 has three arc-shaped grooves at its two ends, namely one first arc-shaped groove 210 and two second arc-shaped grooves 230. The curvature of these three arc-shaped grooves is different. In use, one arc-shaped groove can be selected as the connecting groove as needed, and the fastener 30 is set inside it for connection with the connecting part 110. The other two arc-shaped grooves are used as positioning grooves, and the positioning pins 60 are set inside them. When only one arc-shaped groove is selected as the connecting groove, the arc-shaped structure 220 can present mounting surfaces with different curvatures, so that the display frame presents multiple different mounting curvatures, further improving the application range of the display frame.

[0041] Furthermore, in other preferred embodiments of this utility model, the two ends of the two sliding rods 20 are respectively provided with receiving grooves 240 for accommodating the ends of the fastener 30 and the positioning pin 60, and the second arc-shaped sliding groove 230 and the first arc-shaped sliding groove 210 are both provided in the receiving grooves 240.

[0042] Specifically, the two receiving grooves 240 are respectively located at the two ends of the sliding rod 20. The second arc-shaped sliding groove 230 and the first arc-shaped sliding groove 210 are both located in the receiving grooves 240, and the ends of the fastener 30 and the positioning pin 60 can be accommodated in the receiving grooves 240, so that the ends of the fastener 30 and the positioning pin 60 do not protrude from the surface of the sliding rod 20, thereby avoiding obstacles to the splicing of the two display frames in this direction.

[0043] Furthermore, in other preferred embodiments of the present invention, the front end of the connecting portion 110 is recessed inward, the sliding rod 20 is connected to the recessed portion, and the end of the sliding rod 20 is flush with the non-recessed portion of the connecting portion 110.

[0044] Specifically, the end of the connecting part 110 away from the fixed bracket 10 is recessed towards the center of the frame, and the end of the sliding rod 20 is connected to the recessed part, so that the end of the sliding rod 20 is flush with the non-recessed part of the connecting part 110, that is, the side of the sliding rod 20 away from the center of the frame is flush with the side of the connecting part 110 away from the center of the frame, so that the two display frames can be seamlessly spliced ​​in this direction, improving the splicing effect of the display.

[0045] Furthermore, in other preferred embodiments of this utility model, the display screen frame further includes a reinforcing rod 70, with both ends connected to the two sliding rods 20 respectively, and located at the apex of the arc-shaped structure 220.

[0046] Specifically, the reinforcing rod 70 is located between the two fixed bracket rods 10, and its two ends are respectively connected to the two sliding rods 20. Here, an inwardly recessed groove is provided at the center of the two arc-shaped structures 220, and the two ends of the reinforcing rod 70 are respectively located in the groove. The two first elastic pieces 201 and the plurality of second elastic pieces 40 span over the reinforcing rod 70 and are detachably connected to the reinforcing rod 70 by screws. With this design, the strength and overall integrity of the display frame can be enhanced by the reinforcing rod 70.

[0047] Furthermore, in other preferred embodiments of the present invention, the display screen frame further includes handles 80, and the two handles 80 are respectively connected to the side of the two fixed brackets 10 facing away from the second elastic sheet 40.

[0048] Furthermore, in other preferred embodiments of the present invention, the display screen frame further includes a power supply compartment 90, which is used to house a power supply and other electronic components. The power supply compartment 90 is located at the center of the two sliding rods 20 and is connected to the side of the two sliding rods 20 facing away from the second elastic sheet 40.

[0049] In addition, this utility model embodiment also provides an LED display screen, which includes an LED panel and any of the display screen frames described in the above embodiments.
