Description

Technical Field

[0001] This invention relates to the field of LED bracket technology, specifically to an LED bracket structure. Background Technology

[0002] In a broad sense, LED brackets refer to structural components used to support, fix, and install LED devices or equipment. In the field of LED displays, LED brackets specifically refer to structural devices used to install and fix display cabinets or modules. They are important supporting components for the normal operation of large LED screens. With the widespread application of LED display technology in daily life, such as outdoor performances, stage events, conference displays, and commercial advertising, LED displays have become an important carrier for information dissemination and visual expression. Since the display screen itself is usually composed of multiple modules and has a large overall size, it must rely on structural brackets for effective support and fixation during use to ensure its stable and safe operation.

[0003] Commonly used brackets for supporting LED displays in outdoor performances generally consist of multiple vertical columns and horizontal connecting beams, forming a stable installation frame structure to bear the weight of the entire screen and ensure that it does not shift or tip over during outdoor operation. Currently, there are two main bracket connection methods commonly used in the market: welding and bolt assembly. Welded structures are usually pre-processed in the factory, with strong integrity, and can be directly positioned and used during installation. However, their one-piece structure makes transportation and handling extremely inconvenient, occupies a lot of space, and cannot be folded when not in use. Bolted assembly structures are more flexible in transportation than welded structures, but their assembly process involves the one-to-one connection and tightening of multiple components, which is time-consuming and labor-intensive, and not conducive to rapid deployment, especially in the case of temporary performances or stage scenery requirements, resulting in low efficiency. Moreover, most existing LED display brackets lack flexibility in structural design. After assembly, the LED display can only be displayed in a fixed orientation, and the orientation of the screen cannot be flexibly adjusted according to different venues, audience viewing angles, or lighting environments, reducing the adaptability of the usage scenarios. The overall structure is bulky, which is particularly inconvenient when facing the needs of temporary and frequent venue changes. Summary of the Invention

[0004] This invention provides an LED bracket structure that solves the problems of the two main connection methods currently used for LED display brackets on the market: welding and bolt assembly. While the welded structure has strong integrity and is easy to install, it is bulky, takes up a lot of space, and is inconvenient to transport and store. The bolt assembly structure is easy to transport and has a certain degree of flexibility, but the assembly is cumbersome and time-consuming, which is not conducive to rapid deployment. In addition, the existing brackets can only be installed on one side, which makes it difficult to adapt to the needs of different venues and audience viewing angles. The overall structure is bulky and not suitable for temporary use scenarios with frequent changes in multiple venues.

[0005] This invention provides an LED support structure, including a C-shaped support platform. Two symmetrically distributed, open-topped bases are slidably mounted on the support platform via an adjustable angle section. Each base is equipped with a mounting mechanism for quick assembly and installation of an LED display screen. The mounting mechanism includes self-locking legs, support rods, support tops, and connecting parts. Several self-locking legs are equidistantly mounted on each base, and a support rod is mounted on the upper part of each self-locking leg. The self-locking legs control the support rod to lie horizontally or be locked vertically depending on whether an LED display screen is being installed. A support top is provided between the rear of the support rod and the base to enhance the stability of the vertically mounted support rod. Each support rod is equipped with a connecting part that engages with the support top. Laterally adjacent connecting parts interlock when unfolded, connecting adjacent support rods together to facilitate LED display screen installation. The adjustable angle section adjusts the orientation of the base to indirectly adjust the display angle of the LED display screen mounted on the support rod.

[0006] In one possible implementation, two angle adjustment parts are provided and are symmetrically distributed on the support. Each angle adjustment part includes an L-shaped guide groove opened on the support. A sliding block that is rotatably connected to the lower end face of the base near the middle of the support is slidably disposed in the transverse section of the L-shaped guide groove. A sliding column that is slidably disposed in the longitudinal section of the L-shaped guide groove is fixedly connected to the lower end face of the base away from the middle of the support.

[0007] In one possible implementation, the base end face is provided with a plurality of positioning holes at equal intervals, the self-locking support foot includes a sliding groove provided on the front and rear opposite sides of the base, the front and rear sliding grooves are slidably connected to a sliding rod by a slider, an L-shaped sliding seat is slidably connected to the outside of the sliding rod, a support column is hinged to the upper end face of the L-shaped sliding seat by a lug, the support rod is fixedly connected to the upper end of the support column, a sliding sleeve is slidably connected to the outside of the support column, a top spring is fixedly connected between the sliding sleeve and the support column, and two positioning pins that cooperate with the positioning holes are symmetrically fixedly connected to the lower end face of the sliding sleeve.

[0008] In one possible implementation, the support top includes an insert groove on the rear end face of the support rod and a crossbeam rod fixedly connected to the rear end face of the base by a fixing block. The lower parts of the left and right groove walls of the insert groove are hinged together with a top rod, and a U-shaped slot is provided on the rear end face of the bottom of the top rod.

[0009] In one possible implementation, the connecting part includes an installation groove formed on the support rod and communicating with the upper part of the mounting groove. The front and rear walls of the installation groove are rotatably connected to rollers via a rotating shaft. A connecting plate is fixedly connected to the outside of the two rollers. A number of snap-fit ​​grooves are equidistantly formed on the rear end face of the connecting plate away from the middle of the support. A number of snap-fit ​​posts that cooperate with the snap-fit ​​grooves are fixedly connected at equal intervals on the front end face of the connecting plate near the middle of the support.

[0010] In one possible implementation, a torsion spring is fixedly connected between the reel and the mounting groove, and an elastic cable is fixedly connected to the upper end of the top rod. The upper end of the elastic cable is divided into two parts, which pass through the mounting groove and are respectively wound and fixed to the outside of the reel.

[0011] In one possible implementation, a rectangular groove is provided on the U-shaped slot, a spring telescopic rod is fixedly connected in the rectangular groove, and a wedge block is fixedly connected to the lower end of the spring telescopic rod.

[0012] In one possible implementation, L-shaped rods are hinged to the upper surfaces of the two bases that are close to each other, and the rear end face of the transverse section of the L-shaped rods is also provided with several identical snap-fit ​​grooves at equal intervals.

[0013] In one possible implementation, the front face of the support is symmetrically provided with two rows of insertion holes. Each insertion hole group consists of several insertion holes that are equidistantly opened on the front face of the base and communicate with the L-shaped guide groove. The front face of the sliding block is also provided with the same insertion holes, and a pin is inserted into one of the insertion holes.

[0014] In one possible implementation, the front side of the outer wall of the positioning post is an inclined surface that gradually approaches its own axis from top to bottom.

[0015] As can be seen from the above technical solutions, the present invention has the following advantages: In this invention, when not installed, the support rod can be laid horizontally and stored in the base, achieving compact folding and centralized storage, significantly reducing the volume occupied. During installation, the support rod is vertically locked by the self-locking feet in the mounting frame mechanism. The top of the support rod and the connecting part support the rear of the support rod and quickly splice adjacent support rods together, achieving rapid assembly. This allows installers to complete the structure without using a large number of tools, greatly reducing the time required for assembly and facilitating rapid deployment.

[0016] In this invention, the controllable deflection of the base is achieved through the coordinated operation of components such as the L-shaped guide groove, sliding block and sliding column in the corner adjustment part, which improves the flexibility of the LED display screen in various application scenarios, enhances the visual experience, adapts to various different scenario requirements, realizes "one frame for multiple uses, one screen for multiple occasions", and expands the application range of the installation.

[0031] To make the above-mentioned objects, features, and advantages of the present invention more apparent and understandable, specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of the present invention. However, the present invention can be practiced in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0032] Please see Figure 1 and Figure 2 This invention provides a technical solution: an LED bracket structure, including a C-shaped support 1. Two symmetrically distributed bases 3 with open tops are slidably mounted on the support 1 via an adjustable angle part 2. Each base 3 is equipped with a mounting bracket mechanism for quick assembly and installation of an LED display screen. The mounting bracket mechanism includes self-locking legs 4, support rods 5, support tops 6, and connecting parts 7. Several self-locking legs 4 are equidistantly installed in each base 3. Each self-locking leg 4 has a support rod 5 mounted on its upper part. The self-locking legs 4 are used to adjust the mounting position according to whether an LED display screen is being installed. The LED display screen controls the support rod 5 to be placed horizontally or locked vertically. The rear of the support rod 5 on the base 3 and the base 3 are provided with a support top 6 to enhance the stability of the vertical support rod 5. Each support rod 5 is equipped with a connecting part 7 that is linked and cooperates with the support top 6. When the horizontally adjacent connecting parts 7 are unfolded, they will interlock to connect the adjacent support rods 5 together to facilitate the installation of the LED display screen. The support rod 5 is provided with mounting holes. The angle adjustment part 2 is used to adjust the orientation of the base 3 in order to indirectly adjust the display angle of the LED display screen installed on the support rod 5.

[0033] Please see Figure 2 , Figure 3 and Figure 4 In this embodiment, the base 3 has several positioning holes 8 equidistantly opened on its end face. The self-locking support leg 4 includes a sliding groove 41 opened on the front and rear opposite sides of the base 3. The two sliding grooves 41 are slidably connected to a sliding rod 42 by a slider. An inverted L-shaped slide block 43 is slidably connected to the outside of the sliding rod 42. A support column 44 is hinged to the upper end face of the L-shaped slide block 43 by a lug. The support rod 5 is fixedly connected to the upper end of the support column 44. A sliding sleeve 45 is slidably connected to the outside of the support column 44. A top spring is fixedly connected between the sliding sleeve 45 and the support column 44. Two positioning posts 46 that cooperate with the positioning holes 8 are symmetrically fixedly connected to the lower end face of the sliding sleeve 45. The front side of the outer wall of the positioning post 46 is an inclined surface that gradually approaches its own axis from top to bottom.

[0034] Please see Figure 2 , Figure 3 , Figure 4 and Figure 5The top of the support 6 includes an insert groove 61 opened on the rear end face of the support rod 5 and a crossbeam rod 62 fixedly connected to the rear part of the upper end face of the base 3 by a fixing block. The lower part of the left and right groove walls of the insert groove 61 are hinged together with a top rod 63. A U-shaped slot 64 is opened on the rear part of the lower end face of the top rod 63. A rectangular groove is opened on the U-shaped slot 64. A spring telescopic rod is fixedly connected in the rectangular groove. A wedge block 65 is fixedly connected to the lower end of the spring telescopic rod.

[0035] Please see Figure 2 , Figure 3 , Figure 6 , Figure 7 and Figure 12 The connecting part 7 includes an installation groove 71 that is opened on the support rod 5 and communicates with the upper part of the mounting groove 61. The front and rear walls of the installation groove 71 are rotatably connected to the rollers 72 via a rotating shaft. The two rollers 72 are fixedly connected to the outside of the two rollers 72. The rear end face of the connecting plate 73 away from the middle of the support 1 has several locking grooves 74 equidistantly opened. The front end face of the connecting plate 73 near the middle of the support 1 has several locking posts 75 that cooperate with the locking grooves 74 equidistantly fixedly connected. The rollers 72 and the installation groove 71 are fixedly connected together by a torsion spring. The upper end face of the top rod 63 is fixedly connected to an elastic cable 76. The upper end of the elastic cable 76 is divided into two, passes through the installation groove 71, and is respectively wound and fixed to the outside of the rollers 72. The upper end faces of the two bases 3 are hinged to the side that is close to each other. The rear end face of the transverse section of the L-shaped rod 9 also has several identical locking grooves 74 equidistantly opened.

[0036] The initial state of the mounting mechanism is as follows: Figure 11 As shown, the support rod 5 lies horizontally in the base 3, facilitating its overall movement to the desired position. First, manually lift the support rod 5 to rotate the support column 44 90 degrees around the lug, making the support rod 5 vertical. Then, push the support rod 5 horizontally to indirectly move the L-shaped slide block 43 horizontally. The L-shaped slide block 43 then moves the slider in the slide groove 41 via the slide rod 42, allowing the support rod 5 to move to the appropriate position. Next, push the support rod 5 forward to indirectly move the L-shaped slide block 43 along the slide rod 42. The L-shaped slide block 43 then moves the sliding sleeve. 45 moves forward, and the sliding sleeve 45 then drives the positioning pin 46 to move. The inclined surface at the front of the positioning pin 46 abuts against the edge of the base 3, causing the positioning pin 46 to push the sliding sleeve 45 upward under the action of the inclined surface until the positioning pin 46 moves up to the position flush with the upper end of the positioning hole 8. Then, under the push of the top spring, the sliding sleeve 45 moves down, driving the positioning pin 46 to be inserted into the positioning hole 8. At the same time, the sliding sleeve 45 moves down and is fitted outside the hinge of the support column 44 and the lug, so that the support rod 5, the support column 44 and the L-shaped slide 43 are on the same vertical line.

[0037] Then, manually pull the top rod 63 backward to rotate it out of the mounting groove 61. The top rod 63 then drives the U-shaped slot 64 to gradually move downward until the U-shaped slot 64 is gradually fitted onto the outside of the crossbeam 62. The U-shaped slot 64 first drives the wedge block 65 to abut against the outside of the crossbeam 62. Then, the wedge block 65 is squeezed by the outer wall of the crossbeam 62, which pushes the spring telescopic rod to retract. When the U-shaped slot 64 is completely fitted onto the outside of the crossbeam 62, the wedge block 65 is driven to pass over the crossbeam 62 and abut against the lower outer wall of the crossbeam 62. This allows the rear part of the top rod 63 to be engaged with the crossbeam 62, thereby achieving the rear support and reinforcement of the support rod 5.

[0038] Rotating the L-shaped rod 9 to the upright position causes the top rod 63 to extend a certain distance by pulling against each other, which in turn pulls the elastic cable 76 to become taut. Then, the lower end of the elastic cable 76 is pulled to move, and the elastic cable 76 then pulls the two rollers 72 wound around its upper ends to rotate (the two rollers 72 in the mounting groove 71 rotate in opposite directions). The rollers 72 then drive the connecting plate 73 to rotate, causing the connecting plate 73 to extend out of the mounting groove 71. The two adjacent connecting plates 73, after unfolding, drive the locking post 75 and the locking groove 74 to lock together, thus connecting the two adjacent support rods 5 together. When the connecting plate 73 near the L-shaped rod 9 unfolds, it drives the locking post 75 to slide into the locking groove 74 located on the L-shaped rod 9, thus controlling the assembly of the mounting frame mechanism. Then, the LED display blocks are installed on the support rods 5 in sequence through the mounting holes according to the existing installation method for assembly.

[0039] After the LED display screen is used, remove it from the support rod 5. Then, manually turn the top rod 63 upward to rotate it, causing the U-shaped slot 64 to fall off the crossbeam 62. Turn the top rod 63 upward to return it into the mounting slot 61. At the same time, the elastic cable 76 loses the pull of the top rod 63. Then, under the action of the torsion spring, it drives the roller 72 to reverse. The roller 72 then drives the connecting plate 73 to retract into the mounting slot 71. Then, manually pull the sliding sleeve 45 upward to move it up and drive the positioning pin 46 out of the positioning hole 8. Then, push the support rod 5 to move backward. The support plate then drives the L-shaped slide 43 to move backward along the slide rod 42 through the support column 44. Then, manually push the support rod 5 to drive the support column 44 to rotate laterally around the lug, so that the support rod 5 lies horizontally on the base 3.

[0040] In addition, several casters with self-locking function can be installed on the lower part of the support 1 to make the support 1 easier to move.

[0041] Please see Figure 1 , Figure 8 and Figure 9In this embodiment, two angle adjustment parts 2 are provided and are symmetrically distributed on the support 1. The angle adjustment part 2 includes an L-shaped guide groove 21 opened on the support 1. A sliding block 22 is rotatably connected to the lower end face of the base 3 near the middle of the support 1 and is slidably disposed in the transverse section of the L-shaped guide groove 21. A sliding column 23 is fixedly connected to the lower end face of the base 3 away from the middle of the support 1 and is slidably disposed in the longitudinal section (front and rear direction) of the L-shaped guide groove 21. Two rows of insertion hole groups are symmetrically arranged on the front end face of the support 1. Each insertion hole group consists of several insertion holes 24 that are equidistantly opened on the front end face of the base 3 and communicate with the L-shaped guide groove 21. The front end face of the sliding block 22 is also provided with the same insertion holes 24. A pin 25 is inserted into one of the insertion holes 24.

[0042] When it is necessary to adjust the orientation of the LED display screen mounted on the support rod 5, first pull the pin 25 forward to pull it out of the socket 24. Then, manually push the front end of the base 3 away from the middle of the support 1, so that the sliding column 23 moves backward along the longitudinal section of the L-shaped guide groove 21. The base 3 then drives the sliding block 22 to slide along the transverse section of the L-shaped guide groove 21, so that the base 3 deflects and adjusts its position. This allows the front orientation of the two bases 3 to be adjusted separately, thereby indirectly adjusting the display direction of the LED display screen on the base 3. At this time, the sliding block 22 drives the socket 24 on itself to align with another socket 24 on the support 1. Insert the pin 25 into the corresponding socket 24 to limit the position of the sliding block 22 and prevent the base 3 from moving after the position is adjusted.

[0043] By adjusting the two bases 3 to face different positions, two LED displays can be installed in different locations, allowing for the simultaneous installation of two LED displays showing different content (such as...). Figure 10 As shown in b), when the front sides of the two bases 3 are on the same horizontal line, the same LED display screen can be installed together (e.g., Figure 10 (as shown in a) improves installation flexibility.

[0044] When installing the LED display screen, first rotate the support rod 5 to a vertical position and use the self-locking foot 4 to lock and limit the support rod 5 at this time. Then, manually touch the top of the support rod 6 to support the rear of the support rod 5. At the same time, the top of the support rod 6 touches the connecting part 7 to connect two adjacent support rods 5 together. Then, install the LED display splicing blocks onto the support rods 5 one by one. When used in scenarios where the LED display screen needs to be frequently adjusted, first assemble the LED display screen on the support rod 5 on one of the bases 3. Then, push the base 3 to drive the sliding column 23 to slide in the L-shaped guide groove 21, causing the base 3 to deflect, thereby adjusting the display direction of the screen. After use, first remove the LED display screen from the support rod 5. Then, manually reset the top of the support rod 6. Then, control the self-locking foot 4 to release the limit on the support rod 5. Then, manually push the support rod 5 backward and then push the support rod 5 to rotate horizontally, so that the support rod 5 lies horizontally on the base 3, which is convenient for quick folding and storage.
