Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a connection mechanism for installing LED displays. Background Technology

[0002] An LED display screen is a flat panel display composed of small LED module panels used to display various information such as text, images, and videos. Currently, common LED display screen installation and connection mechanisms on the market have many shortcomings. Some connection mechanisms use a fixed installation method, making it difficult to adjust the screen angle according to actual needs and failing to meet the display requirements of diverse scenarios. Some mechanisms with adjustment functions have low adjustment precision, making it difficult to achieve precise angle control, resulting in deviations in the displayed image. In addition, existing installation structures are cumbersome to operate when maintaining and replacing the screen, consuming a lot of manpower and time costs. Therefore, we have launched a connection mechanism for LED display screen installation. Utility Model Content

[0003] The main objective of this invention is to provide a connection mechanism for installing LED displays, which can effectively solve the problems in the background art.

[0004] To achieve the above objectives, the technical solution adopted by this utility model is as follows:

[0005] A connection mechanism for installing an LED display screen includes a mounting base and fixing bolts. A stabilizing plate is fixedly connected to the lower part of the inner wall of the mounting base. An adjusting device is fixedly connected to one side of the lower end of the stabilizing plate. A limiting groove is opened on the lower part of the inner wall of the mounting base, and the limiting groove is located directly below the stabilizing plate.

[0006] The adjustment device includes a drive motor. The output end of the drive motor passes through the stabilizing plate and is fixedly connected to a circular block. Two intermittent columns are fixedly connected to the upper end of the circular block. The intermittent columns are rotatably connected to an inner ring frame. The inner ring wall of the inner ring frame has several intermittent arc grooves. A limit ring is fixedly connected to the middle of the outer ring wall of the inner ring frame. Six connecting frames are fixedly connected around the upper end of the inner ring frame. A connecting shaft block is fixedly connected to the inner side of the connecting frames. An installation component is fixedly connected to the upper end of the connecting shaft block. The drive motor is fixedly installed on one side of the lower end of the stabilizing plate.

[0007] Preferably, the mounting assembly includes a main rod, a fixing plate fixedly connected to the middle of the outer surface of the main rod, side rods fixedly connected to the upper left and upper right of the fixing plate, lower mounting brackets fixedly connected to the lower outer surface of the side rods and the lower outer surface of the main rod, upper mounting brackets sleeved on the upper outer surface of the side rods and the upper outer surface of the main rod, resistance pads fixedly connected to the lower front of the upper mounting bracket and the upper front of the lower mounting bracket, and the bottom of the main rod fixedly connected to the upper end of the connecting shaft block.

[0008] Preferably, the mounting base is fixedly connected to ear plates on all four sides of its outer side, and the display device is fixedly mounted on the upper front end of the adjustment device by three fixing bolts.

[0009] Preferably, the display device includes a frame plate, and the inner frame wall of the frame plate is fixedly connected to a liquid crystal panel, a prism plate, a diffuser plate and a light guide plate from front to back.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] 1. In this utility model, the precise cooperation of the drive motor, intermittent column, and intermittent arc groove is utilized. The drive motor drives the circular block to rotate, causing the intermittent column to mesh with the semi-circular and equidistantly distributed intermittent arc groove, achieving precise intermittent rotation adjustment. Users can adjust the LED display screen to any suitable angle as needed according to different usage scenarios, effectively avoiding display deviation problems caused by improper angle. At the same time, the design of the limiting ring and limiting slide groove restricts the movement trajectory of the inner ring frame, ensuring that it can only rotate stably in the horizontal direction, ensuring that the display screen will not shake or shift during the adjustment process. The six equidistantly distributed connecting frames evenly transmit power, ensuring smooth rotation of the display screen, realizing high-precision and multi-angle flexible adjustment to meet the display needs of diverse scenarios.

[0015] 2. In this utility model, the frame plate of the display device is installed and fixed by the snap-fit ​​structure of the upper and lower mounting brackets in conjunction with the resistance pad. This structure can not only quickly complete the installation and disassembly of the display screen, but also ensure that the friction provided by the resistance pad can ensure that the frame plate is firmly clamped. In addition, the mounting screw holes on the frame plate can be further fixed with fixing bolts to form a double insurance. When maintaining or replacing the display screen, no complicated tools and a lot of manpower are required. Operators can quickly disassemble and install the display screen, which greatly reduces the time and labor costs in the maintenance and replacement process. Attached Figure Description

[0026] Please see Figure 1-6 This utility model provides a technical solution:

[0027] A connection mechanism for installing an LED display screen includes a mounting base 1 and fixing bolts 5. A stabilizing plate 6 is fixedly connected to the lower part of the inner wall of the mounting base 1. An adjusting device 3 is fixedly connected to one side of the lower end of the stabilizing plate 6. A limiting groove 7 is opened on the lower part of the inner wall of the mounting base 1, and the limiting groove 7 is located directly below the stabilizing plate 6.

[0028] Ear plates 2 are fixedly connected to the outer perimeter of the mounting base 1. The display device 4 is fixedly installed on the upper front of the adjustment device 3 by three fixing bolts 5.

[0029] In this embodiment, the adjusting device 3 includes a drive motor 31. The output end of the drive motor 31 passes through the stabilizing plate 6 and is fixedly connected to a circular block 35. Two intermittent columns 36 are fixedly connected to the upper end of the circular block 35. The intermittent columns 36 are meshed and rotatably connected to an inner ring frame 39. The inner ring wall of the inner ring frame 39 has several intermittent arc grooves 310. A limit ring 32 is fixedly connected to the middle of the outer ring wall of the inner ring frame 39. Six connecting frames 34 are fixedly connected around the upper end of the inner ring frame 39. The inner sides of the connecting frames 34 are all fixedly connected to a common... A connecting shaft block 37 is fixedly connected to an installation component 38 at its upper end. A drive motor 31 is fixedly installed on one side of the lower end of a stabilizing plate 6. A limiting ring 32 is slidably connected in a limiting groove 7. Six connecting frames 34 are distributed in a ring at equal intervals around the connecting shaft block 37. Several intermittent arc grooves 310 are distributed in a ring at equal intervals around the inner ring frame 39. The intermittent arc grooves 310 are all semi-circular structures. The positional dimensions of the two intermittent columns 36 are adapted to the positional dimensions of the intermittent arc grooves 310.

[0030] Through the above scheme: when it is necessary to adjust the angle of the display device 4, the drive motor 31 fixedly installed on one side of the lower end of the stabilizing plate 6 is activated. The output end of the drive motor 31 passes through the stabilizing plate 6 and drives the circular block 35 to rotate. The two intermittent columns 36 at the upper end of the circular block 35 rotate accordingly. Since the intermittent columns 36 are meshed and rotated with several semi-circular and equidistantly distributed intermittent arc grooves 310 on the inner ring wall of the inner ring frame 39, and the positions and dimensions of the two are compatible, when the circular block 35 rotates, the intermittent columns 36 will push the inner ring frame 39 to rotate. The limiting ring 32 in the middle of the outer ring wall of the inner ring frame 39 slides in the limiting slide groove 7. The limiting slide groove 7 is located directly below the stabilizing plate 6. This structure restricts the movement trajectory of the inner ring frame 39, so that it can only rotate in a ring. When the inner ring frame 39 rotates, the six connecting frames 34, which are equidistantly distributed in a ring around the connecting shaft block 37 at the upper end, rotate. This will drive the connecting shaft block 37 and the mounting component 38 fixed on its upper end to rotate synchronously, thereby driving the display device 4 to rotate and achieving multi-angle adjustment. The adjustment device 3, through the cooperation of the drive motor 31 with the intermittent column 36 and the intermittent arc groove 310, achieves precise intermittent rotation adjustment, which can adjust the display device 4 to a suitable angle as needed to meet the viewing needs in different usage scenarios. Through the design of the limiting ring 32 and the limiting slide 7, the stability and accuracy of the rotation of the inner ring frame 39 are ensured, avoiding shaking or deviation during the adjustment process, and enhancing the reliability of the entire connection mechanism. Through the six ring-shaped equidistantly distributed connecting frames 34, the power can be transmitted evenly, making the rotation of the mounting component 38 and the display device 4 more stable, extending the service life of the equipment, reducing maintenance costs, and making it suitable for LED display installation and adjustment work in various environments.

[0031] In this embodiment, the mounting assembly 38 includes a main rod 381. A fixing plate 382 is fixedly connected to the middle of the outer surface of the main rod 381. Side rods 386 are fixedly connected to the upper left and upper right sides of the fixing plate 382. Lower mounting brackets 383 are fixedly connected to the lower outer surface of the side rods 386 and the lower outer surface of the main rod 381. Upper mounting brackets 384 are sleeved on the upper outer surface of the side rods 386 and the upper outer surface of the main rod 381. The lower front of the upper mounting bracket 384 is connected to the lower mounting bracket. The upper front part of the mounting bracket 383 is fixedly connected with a resistance pad 385. The bottom of the main rod 381 is fixedly connected to the upper end of the connecting shaft block 37. The display device 4 includes a frame plate 41. The inner frame wall of the frame plate 41 is fixedly connected with a liquid crystal panel 46, a prism plate 45, a diffuser plate 44 and a light guide plate 43 from front to back. The upper left, upper middle and upper right parts of the frame plate 41 are all provided with mounting screw holes 42. The frame plate 41 is snapped between the upper mounting bracket 384 and the lower mounting bracket 383.

[0032] Through the above scheme: the mounting component 38 is fixedly connected to the connecting shaft block 37 at the bottom of the main rod 381. When the connecting shaft block 37 rotates with the inner ring frame 39, the main rod 381 rotates synchronously. The fixing plate 382 in the middle of the main rod 381 transmits the rotation of the main rod 381 to the upper mounting frame 384 and the lower mounting frame 383 through the inserted and fixed side rod 386. The frame plate 41 of the display device 4 is snapped between the upper mounting frame 384 and the lower mounting frame 383. The resistance pad 385 provides friction to ensure that the frame plate 41 is firmly clamped. The mounting screw holes 42 of the frame plate 41 can be further fixed with the fixing bolts 5 to form a double insurance. The liquid crystal panel 46, prism plate 45, and diffuser plate 4 The display device 4 is fixed sequentially to the light guide plate 43 on the inner frame wall to form a complete display module. It rotates synchronously with the frame plate 41. The fastening structure of the upper mounting bracket 384 and the lower mounting bracket 383, combined with the resistance pad 385, enables the quick installation and disassembly of the display device 4, facilitating maintenance and replacement. The support structure of the side rod 386 and the main rod 381 enhances the overall rigidity and effectively reduces the shaking of the display device 4. The design of the mounting screw hole 42 allows for the selection of fixing bolts 5 according to actual needs, improving the structural adaptability. The layered arrangement of components such as the liquid crystal panel 46 and the prism plate 45 ensures the uniformity and stability of the display effect. The optical structure remains intact during rotation.

[0033] It should be noted that this utility model is a connection mechanism for installing an LED display screen. First, during the installation stage, the entire connection mechanism is fixed in the required position by the ear plates 2 around the outer perimeter of the mounting base 1. The frame plate 41 of the display device 4 is snapped between the upper mounting bracket 384 and the lower mounting bracket 383. The mounting screw holes 42 on the frame plate 41 can be further fixed with other connecting parts to ensure the stable installation of the display device 4. The internal liquid crystal panel 46, prism plate 45, diffuser plate 44 and light guide plate 43 together constitute the core part of the LED display. When it is necessary to adjust the angle or position of the display device 4, the drive motor 31 in the adjustment device 3 is activated. The drive motor 31 is installed on one side of the lower end of the stabilizing plate 6. Its output end passes through the stabilizing plate 6 and drives the circular block 35 to rotate. The two intermittent columns 36 at the upper end of the circular block 35 rotate accordingly. Since the intermittent columns 36 are meshed and rotated with the intermittent arc grooves 310 of the inner ring wall of the inner ring frame 39, and the position and size of the intermittent columns 36 are adapted to the intermittent arc grooves 310, several intermittent arc grooves The inner ring frame 39 is equidistantly distributed in a ring around the inner ring frame 39. Therefore, when the circular block 35 rotates, the intermittent column 36 will push the inner ring frame 39 to rotate. The limiting ring 32 in the middle of the outer ring wall of the inner ring frame 39 slides in the limiting groove 7, which is located directly below the stabilizing plate 6. This structure restricts the movement trajectory of the inner ring frame 39, allowing it to rotate only in the horizontal direction, ensuring the stability and accuracy of the adjustment process. When the inner ring frame 39 rotates, the six connecting frames 34 around its upper perimeter are equidistant from the connecting shaft block 37. The equidistant ring distribution will drive the connecting shaft block 37 and the mounting assembly 38 fixed on its upper end to rotate synchronously. The bottom of the main rod 381 in the mounting assembly 38 is connected to the connecting shaft block 37. The side rod 386 is inserted and fixedly connected to the fixing plate 382 on the outer surface of the main rod 381. The upper mounting bracket 384 and lower mounting bracket 383 on the main rod 381 and the side rod 386, together with the resistance pad 385, drive the display device 4 to rotate, thereby realizing the adjustment of the angle of the display device 4 to meet different display needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
