Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to an LED display installation and positioning device. Background Technology

[0002] An LED display screen is an electronic display device that uses light-emitting diodes (LEDs) as the light source. An LED is a solid-state semiconductor device that can directly convert electrical energy into light energy and emit light when current passes through it. An LED display screen forms display units by arranging numerous LEDs in a certain array, such as a matrix arrangement. Under the control of the driving circuit, these units light up and turn off the LEDs at different positions according to the input electrical signal, thereby converting the electrical signal into visible optical images and text information.

[0003] One existing method for installing LED displays involves manually drilling holes in walls or other mounting surfaces using an electric drill, then manually hanging the display. However, manual hanging cannot guarantee the horizontal and vertical alignment of the display after installation. If the display is not horizontal or vertical, it will affect the viewing experience and cause inconvenience in subsequent use. Existing technology uses mounting brackets manufactured with high-precision molds and machining processes. These brackets have high flatness and verticality accuracy, providing a more accurate benchmark for display installation and reducing installation errors caused by bracket issues. However, these high-precision brackets are usually custom-designed for specific models and sizes of displays. When different sizes and shapes of displays need to be installed, existing brackets cannot be used for different displays, requiring the design and manufacture of new brackets. This increases inventory costs and management difficulties, further inconveniencing subsequent display installation work. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides an LED display screen installation and positioning device, which aims to improve the existing technology. When it is necessary to install displays of different sizes and shapes, the existing brackets cannot be used to install different displays, which causes inconvenience to the subsequent installation of the displays.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: an LED display screen installation and positioning device, comprising a base, a hollow cube mounted on the top of the base, a motor fixedly connected to the bottom wall of the hollow cube, the output end of the motor penetrating the top of the hollow cube and fixedly connected to a circular block, double-section rotating rods fixedly connected to the left and right sides of the outer wall of the circular block, multiple slide rails fixedly connected at equal intervals to the inner bottom wall of the hollow cube, sliding blocks slidably connected to the outer wall of the slide rails, the other end of the double-section rotating rods fixedly connected to the outer wall of the sliding block, a connecting plate fixedly connected to the adjacent side of the outer wall of the sliding block, a fixing plate fixedly connected to the top of the outer wall of the connecting plate, and a semi-circular fixing block slidably connected to the adjacent side of the outer wall of the fixing plate, and an adjustment mechanism mounted on the top of the base for adjusting the height.

[0006] As a further description of the above technical solution:

[0007] The adjusting mechanism includes an internal threaded ring bracket, which is installed on the top of the base. A threaded rod is rotatably connected to the top of the internal threaded ring bracket, and a bevel gear is fixedly connected to the bottom end of the threaded rod. A fixed square plate is fixedly connected to the left side of the outer wall of the base, and a fixed short rod is rotatably connected to the middle of the fixed square plate. A bevel gear is fixedly connected to the right end of the outer wall of the fixed short rod. A movable ring is threaded to the outer wall of the threaded rod, and the bevel gear meshes with the bevel gear. An internal sliding plate is fixedly connected to the top of the internal threaded ring bracket.

[0008] As a further description of the above technical solution:

[0009] A hollow box is fixedly connected to the top rear side of the base, and a drawer is slidably connected inside the hollow box.

[0010] As a further description of the above technical solution:

[0011] Two handles are fixedly connected to the rear side of the outer wall of the drawer.

[0012] As a further description of the above technical solution:

[0013] A handle is fixedly connected to both the front and rear sides of the outer wall of the base.

[0014] As a further description of the above technical solution:

[0015] The outer wall of the semi-circular fixing block is fixedly connected with an anti-slip plate.

[0016] As a further description of the above technical solution:

[0017] A throttle is fixedly connected to the left end of the outer wall of the fixed short rod.

[0018] As a further description of the above technical solution:

[0019] The base is equipped with casters at all four corners.

[0020] This utility model has the following beneficial effects:

[0021] 1. In this utility model, the circular block at the output end is rotated by turning on the motor. When the circular block rotates, it will drive the double-section rotating rod on the outer wall to rotate. Since one end of the double-section rotating rod is fixedly connected to the outer wall of the sliding block, when the double-section rotating rod rotates, it will pull the sliding block to slide on the slide rail. Finally, when the sliding block slides, it will drive the semi-circular fixing blocks on both sides of the fixing plate to slide and clamp and fix the display screens of different sizes. This avoids the problem that the existing brackets cannot be used to install different display screens when different sizes and shapes of display screens are required, thus avoiding the inconvenience caused to the subsequent installation of the display screens.

[0022] 2. In this utility model, by rotating the fixed short rod in the middle of the fixed square plate, the second bevel gear on the right end is driven to rotate. When the second bevel gear rotates, it will mesh with the first bevel gear at the bottom of the threaded rod, causing the threaded rod to rotate. When the threaded rod rotates, it will drive the moving ring on the outer wall to adjust up and down to adapt to different installation and positioning heights, thereby achieving the effect of adjusting the installation of the display screen according to different installation positions.

The sliding block 12 slides on the slide rail 16. A connecting plate 17 is fixedly connected to each adjacent side of the outer wall of the sliding block 12. A fixing plate 11 is fixedly connected to the top of the outer wall of the connecting plate 17. A semi-circular fixing block 9 is slidably connected to each adjacent side of the outer wall of the fixing plate 11. The semi-circular fixing block 9 plays a role in sliding clamping. An adjustment mechanism 2 is installed on the top of the base 1. The adjustment mechanism 2 is used to adjust the height. A hollow box 7 is fixedly connected to the rear top of the base 1.

[0032] Specifically, the motor 14 drives the circular block 15 at the output end to rotate. When the circular block 15 rotates, it drives the double-section rotating rod 13 on the outer wall to rotate. Since one end of the double-section rotating rod 13 is fixedly connected to the outer wall of the sliding block 12, when the double-section rotating rod 13 rotates, it pulls the sliding block 12 to slide on the slide rail 16. Finally, when the sliding block 12 slides, it drives the semi-circular fixing blocks 9 on the outer wall of the fixing plate 11 on both sides to clamp and fix the display screens of different sizes.

[0033] Reference Figure 1 , Figure 2 and Figure 5 The adjusting mechanism 2 includes an internal threaded ring bracket 201, which is mounted on the top of the base 1. A threaded rod 203 is rotatably connected to the top of the internal threaded ring bracket 201, and a bevel gear 202 is fixedly connected to the bottom end of the threaded rod 203. The bevel gear 202 engages in rotation. A fixed square plate 208 is fixedly connected to the left side of the outer wall of the base 1, and a fixed short rod 207 is rotatably connected to the middle of the fixed square plate 208. A bevel gear 206 is fixedly connected to the right end of the outer wall of the fixed short rod 207. By rotating the fixed short rod 207, the bevel gear 206 at the right end of the outer wall can be driven. Gear 206 meshes with bevel gear 202, causing the threaded rod 203 to rotate.

[0034] Specifically, by rotating the fixed short rod 207 in the middle of the fixed square plate 208, the bevel gear 206 on the right end is driven to rotate. When the bevel gear 206 rotates, it will mesh with the bevel gear 202 at the bottom of the threaded rod 203, causing the threaded rod 203 to rotate. When the threaded rod 203 rotates, it will drive the moving ring 204 on the outer wall to adjust up and down to adapt to different installation and positioning heights.

[0035] Reference Figure 1 and Figure 2 A handle 5 is fixedly connected to the left end of the outer wall of the fixed short rod 207. The handle 5 can facilitate the rotation of the fixed short rod 207. Universal wheels 4 are installed at the four corners of the bottom of the base 1. The universal wheels 4 at the bottom of the base 1 can facilitate the staff to move the equipment to different places for use.

[0036] Specifically, a handle 5 is fixedly connected to the left end of the outer wall of the fixed short rod 207. The handle 5 can facilitate the rotation of the fixed short rod 207. Universal wheels 4 are installed at the four corners of the bottom of the base 1. The universal wheels 4 at the bottom of the base 1 can facilitate the staff to move the equipment to different places for use.

[0037] Working principle: By turning on the motor 14, the circular block 15 at the output end is driven to rotate. When the circular block 15 rotates, it will drive the double-section rotating rod 13 on the outer wall to rotate. Since one end of the double-section rotating rod 13 is fixedly connected to the outer wall of the sliding block 12, when the double-section rotating rod 13 rotates, it will pull the sliding block 12 to slide on the slide rail 16. Finally, when the sliding block 12 slides, it will drive the semi-circular fixing blocks 9 on the outer wall of the fixing plate 11 on both sides to clamp and fix the display screens of different sizes. This avoids the problem that the existing brackets cannot be used to install different display screens when different sizes and shapes of display screens are required, thus avoiding the inconvenience caused to the subsequent installation of the display screens.

[0038] By rotating the fixed short rod 207 in the middle of the fixed square plate 208, the second bevel gear 206 on the right end is driven to rotate. When the second bevel gear 206 rotates, it will mesh with the first bevel gear 202 at the bottom of the threaded rod 203, causing the threaded rod 203 to rotate. When the threaded rod 203 rotates, it will drive the moving ring 204 on the outer wall to adjust up and down to adapt to different installation and positioning heights, thereby achieving the effect of adjusting the installation of the display screen according to different installation positions.
