Description

Technical Field

[0001] This utility model relates to the field of LED display installation technology, specifically to an auxiliary positioning device for LED display installation. Background Technology

[0002] An LED display screen is a type of flat panel display composed of small LED module panels. LED stands for Light Emitting Diode. It is a display method that controls semiconductor light-emitting diodes. These diodes are made of compounds of gallium (Ga) with arsenic (As), phosphorus (P), nitrogen (N), and indium (In). When electrons and holes recombine, they emit visible light, thus they can be used to make light-emitting diodes. They are used in circuits and instruments as indicator lights, or to form text or number displays. Gallium arsenide phosphide diodes emit red light, gallium phosphide diodes emit green light, silicon carbide diodes emit yellow light, and indium gallium nitride diodes emit blue light. LED displays are generally used to display various information such as text, images, video, and recorded signals. LED displays require mounting equipment for installation.

[0003] According to the authorized announcement number CN219933436U, a specific LED display installation device is described, including a support rod and a fixing plate above a base. The fixing plate is located above the support rod. The device further includes: a clamping assembly located on the fixing plate, driven by a power source to rotate and adjust its horizontal distance, used to clamp LED displays of different lengths, and clamping the LED displays horizontally and vertically through threaded limits; and an air-guiding assembly located in the middle of the support rod, which enhances wind pressure to guide airflow and disperse wind force. This invention, by setting up the clamping assembly and the air-guiding assembly, allows the clamping assembly to fix and clamp the top and bottom of the LED display according to its length; the air-guiding assembly disperses the force of the wind blowing on the support rod, making it less prone to tilting when supporting the fixing plate.

[0004] Based on the search of the aforementioned patents and the findings of existing equipment, while the aforementioned equipment ensures the stability of LED display installation during application, it does not have an auxiliary centering and positioning structure in actual use. This forces installers to rely solely on visual inspection and manual operation to adjust the position of the display screen to achieve a rough centering effect, making the entire installation process cumbersome and time-consuming. The lack of precise centering of the display screen results in an uneven overall installation effect, affecting the visual quality. Utility Model Content

This solves the problem that the above-mentioned devices do not have an auxiliary centering positioning structure, which leads to installers having to rely solely on visual inspection and manual operation to adjust the position of the display screen to achieve a rough centering effect, making the entire installation process cumbersome and time-consuming. Furthermore, if the display screen is not precisely centered, it will result in an uneven overall installation effect and affect the visual effect.

[0006] To achieve the above objectives, this utility model provides the following technical solution: an auxiliary positioning device for LED display installation, comprising a base, a mounting box, a bidirectional threaded rotating rod, a motor, and a movable placement block. The mounting box is fixedly installed on the top of the base. The bidirectional threaded rotating rod is movably connected inside the mounting box. The motor is fixedly installed on the right side of the mounting box, and the output end of the motor is fixedly connected to the right end of the bidirectional threaded rotating rod. The movable placement block is threadedly connected to the left and right sides of the surface of the bidirectional threaded rotating rod. Positioning and centering mechanisms are fixedly connected to the left and right sides of the back of the mounting box. The positioning and centering mechanism includes a support block, which is fixedly connected to the left and right sides of the back of the mounting box. A bidirectional lead screw is movably connected inside the support block. Movable blocks are threadedly connected to the left and right sides of the surface of the bidirectional lead screw. A centering positioning block is fixedly connected to the top of the movable block. A limit component is provided at the top inside the movable block. An upper fixing component is fixedly connected to the back of the movable placement block.

[0007] In a preferred embodiment of this utility model, the limiting component includes a limiting hole, which is opened at the top inside the movable block. The limiting hole is through-hole, and a limiting rod is slidably connected inside the limiting hole. The left and right ends of the limiting rod are fixedly connected to the support block.

[0008] As a preferred embodiment of this invention, bearings are movably connected to both the left and right sides of the surface of the bidirectional lead screw, and the bidirectional lead screw is movably connected to the support block through the bearings.

[0009] In a preferred embodiment of this utility model, the upper fixing component includes a fixing tube, which is fixedly connected to the back of the movable placement block.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] 1. This utility model, by setting a positioning and centering mechanism, has moving blocks threadedly connected to the left and right sides of the bidirectional lead screw surface, and a centering positioning block fixedly connected to the top of the moving blocks. When the bidirectional lead screw rotates, the moving blocks can drive the centering positioning block to center the LED display screen, so that the display screen can be accurately positioned in the center of the installation location, improving the positioning accuracy and precision. This solves the problem that the above-mentioned equipment does not have an auxiliary centering positioning structure, which leads to installers having to rely on visual inspection and manual operation to adjust the position of the display screen to achieve a rough centering effect, making the entire installation process cumbersome and time-consuming. If the display screen is not accurately centered, it will lead to an uneven overall installation effect and affect the visual effect. This invention achieves the effect of centering positioning.

[0015] 2.

[0016] 3. By incorporating bearings, this utility model allows the bidirectional lead screw to be movably mounted to the support block via the bearings, thereby enabling the bidirectional lead screw to rotate smoothly, reducing friction during rotation, and extending the service life of the bidirectional lead screw.

Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] like Figures 1 to 3 As shown, the present invention provides an auxiliary positioning device for LED display installation, including a base 1, a mounting box 2, a bidirectional threaded rotating rod 3, a motor 4, and a movable placement block 5. The mounting box 2 is fixedly installed on the top of the base 1. The bidirectional threaded rotating rod 3 is movably connected inside the mounting box 2. The motor 4 is fixedly installed on the right side of the mounting box 2, and the output end of the motor 4 is fixedly connected to the right end of the bidirectional threaded rotating rod 3. The movable placement block 5 is threadedly connected to the left and right sides of the surface of the bidirectional threaded rotating rod 3. The left and right sides of the back of the mounting box 2 are both fixedly connected to a positioning centering mechanism 6. The positioning centering mechanism 6 includes a support block 61, which is fixedly connected to the left and right sides of the back of the mounting box 2. The support block 61 is movably connected to a bidirectional lead screw 62. The left and right sides of the surface of the bidirectional lead screw 62 are both threadedly connected to a movable block 63. The top of the movable block 63 is fixedly connected to a centering positioning block 64. A limit component 65 is provided at the top of the interior of the movable block 63. The back of the movable placement block 5 is fixedly connected to an upper fixing component 7.

[0023] refer to Figure 1 , Figure 2 and Figure 3 The limiting component 65 includes a limiting hole 651, which is opened at the top inside the movable block 63. The limiting hole 651 is through-hole, and a limiting rod 652 is slidably connected inside the limiting hole 651. The left and right ends of the limiting rod 652 are fixedly connected to the support block 61.

[0024] As a technical optimization of this utility model, by setting a limiting component 65, when the bidirectional lead screw 62 rotates, the limiting rod 652 restricts the displacement of the moving block 63, so that the moving block 63 can only move in a straight line along the direction of the bidirectional lead screw 62, and avoids it from deviating from the correct movement path due to uneven force or other factors.

[0025] refer to Figure 1 , Figure 2 and Figure 3 The left and right sides of the surface of the bidirectional lead screw 62 are movably connected to bearings 8, and the bidirectional lead screw 62 is movably connected to the support block 61 through the bearings 8.

[0026] As a technical optimization of this utility model, by setting a bearing 8, the bidirectional lead screw 62 is movably installed with the support block 61 through the bearing 8, thereby enabling the bidirectional lead screw 62 to rotate smoothly, reducing the friction during the rotation process, and extending the service life of the bidirectional lead screw 62.

[0027] refer to Figure 1 , Figure 2 and Figure 3 The upper fixing component 7 includes a fixing tube 71, which is fixedly connected to the back of the movable placement block 5. A telescopic plate 72 is slidably connected inside the fixing tube 71. A pressure plate 73 is fixedly connected to the top of the front of the telescopic plate 72. A locking component 74 is provided on the back of the fixing tube 71.

[0028] As a technical optimization of this utility model, the position of the pressure plate 73 can be adjusted by setting the upper fixing component 7, the sliding connection structure of the fixing tube 71 and the telescopic plate 72, which can adapt to LED displays of different heights, improve the versatility and applicability of the device, and fix the LED display from above, forming multi-angle and multi-position positioning and fixing of the LED display, ensuring that the display will not shift during installation and ensuring the accuracy of installation.

[0029] refer to Figure 1 , Figure 2 and Figure 3 The locking assembly 74 includes a sliding groove 741, which is formed on the back of the fixed tube 71. A locking screw 742 is fixedly connected to the bottom of the back of the telescopic plate 72. The locking screw 742 is located inside the sliding groove 741, and a locking block 743 is threadedly connected to the surface of the locking screw 742.

[0030] As a technical optimization of this utility model, by setting the locking component 74, the position of the telescopic plate 72 can be easily locked to ensure that it will not slide due to external force or its own weight, thus ensuring the fixing effect on the LED display screen. The operator can adjust the position of the telescopic plate 72 according to the actual situation, and lock the telescopic plate 72 in the required position through the threaded connection of the locking screw 742 and the locking block 743, thereby enhancing the adjustability and reliability of the device.

[0031] refer to Figure 1 , Figure 2 and Figure 3 Protective pads 9 are attached to the bottom of the pressure plate 73 and the inner side of the center positioning block 64. The protective pads 9 are made of natural rubber.

[0032] As a technical optimization of this utility model, by setting a protective pad 9, the pressure plate 73 and the centering positioning block 64 are prevented from directly contacting the display screen and causing scratches or damage, thus ensuring the appearance integrity of the display screen during installation. The protective pad 9, made of natural rubber, has a certain elasticity and can buffer the pressure of the pressure plate 73 and the centering positioning block 64 on the display screen to a certain extent, preventing damage to the display screen due to excessive pressure.

[0033] refer to Figure 1 , Figure 2 and Figure 3 The right end of the bidirectional lead screw 62 is fixedly connected to a rotary handle 10, which is used to rotate the bidirectional lead screw 62.

[0034] As a technical optimization of this utility model, by setting a rotary handle 10, it is convenient for operators to manually adjust the bidirectional lead screw 62. When the motor 4 malfunctions or requires fine adjustment, the rotary handle 10 can be used to achieve precise control of the bidirectional lead screw 62, which increases the ease of operation and controllability of the device.

[0035] The working principle and usage process of this utility model are as follows: During use, the operator starts the motor 4, and the output end of the motor 4 drives the bidirectional threaded rod 3 to rotate. Depending on the rotation direction of the motor 4 (forward or reverse), the moving placement block 5 will move accordingly to the left or right, thereby adjusting its spacing to accommodate the width of the LED display screen. After adjustment, the operator places the LED display screen inside the moving placement block 5. Then, the LED display screen needs to be centered. At this time, the operator rotates the wheel handle 10 at the right end of the bidirectional lead screw 62, causing the bidirectional lead screw 62 to rotate. As the bidirectional lead screw 62 rotates, the moving blocks 63 on the left and right sides will drive the positioning and centering blocks to move towards each other along the bidirectional lead screw 62, moving them towards the center of the LED display screen, ultimately pushing the display screen to the centered position. During this process, the moving blocks... The limiting hole 651 and limiting rod 652 at the top of the internal part of the 63 ensure that the moving block 63 moves stably along the axial direction of the bidirectional screw 62, preventing it from deviating. This allows the operator to ensure that the LED display screen is in a centered position, increasing aesthetics. Then, the operator moves the telescopic plate 72 so that the pressure plate 73 on the front of the telescopic plate 72 can contact the top of the LED display screen. After the telescopic plate 72 is adjusted to the appropriate position, by rotating the locking block 743, due to the threaded connection between the locking block 743 and the locking screw 742, the locking block 743 will move along the axial direction of the locking screw 742 and make tight contact with the back of the fixing tube 71, locking the telescopic plate 72 in the current position and fixing the telescopic plate 72. This allows the pressure plate 73 to fix the LED display screen from above, thereby ensuring that the LED display screen is in a stable installation environment.

[0036] In summary, this auxiliary positioning device for LED display installation, through the setting of a positioning and centering mechanism 6, has moving blocks 63 threadedly connected to the left and right sides of the surface of the bidirectional lead screw 62, and a centering positioning block 64 fixedly connected to the top of the moving blocks 63. When the bidirectional lead screw 62 rotates, the moving blocks 63 can drive the centering positioning block 64 to center the LED display, so that the display can be accurately positioned in the center of the installation location, improving the positioning accuracy and precision. This solves the problem that the above-mentioned devices do not have an auxiliary centering positioning structure, which leads to installers having to rely on visual inspection and manual operation to adjust the position of the display to achieve a rough centering effect, making the entire installation process cumbersome and time-consuming. If the display is not accurately centered, it will result in an uneven overall installation effect and affect the visual effect.
