Description

Technical Field

[0001] This utility model relates to the field of LED display cabinet edge banding technology, and in particular to a quick-install edge banding device for LED display cabinets. Background Technology

[0002] LED displays, as efficient, clear, and energy-saving display devices, have been widely used in many scenarios such as outdoor advertising, stadiums, stage performances, and transportation hubs. LED displays are typically composed of multiple cabinets spliced ​​together, and the structural stability, installation efficiency, and aesthetic integrity of these cabinets directly affect the overall performance and user experience of the display.

[0003] A search revealed Chinese Patent Publication No. CN221632177U, which discloses an LED display cabinet edge-wrapping device, relating to the field of LED display cabinet edge-wrapping technology. The device includes an LED display cabinet with edge-wrapping profiles on all four outer walls. Each of the four edge-wrapping profiles and the LED display cabinet has mounting holes for installing the edge-wrapping profiles. Mounting screws are installed in the mounting holes, and silicone plugs are placed inside the mounting screws. A connecting mechanism is provided at the right-angled edges of two adjacent edge-wrapping profiles. This application utilizes the cooperation of the edge-wrapping profiles and other components, and uses mounting screws to install and fix the corresponding edge-wrapping profiles. By installing right-angled plastic parts within two adjacent edge-wrapping profiles, the edge-wrapping of the entire LED display cabinet can be completed. This edge-wrapping design is thin and lightweight, allowing for direct edge-wrapping of already installed screens, thereby improving the efficiency of cabinet assembly.

[0004] The above-mentioned methods can improve the efficiency of cabinet assembly and shorten the assembly time to a certain extent. However, the installation process of the edge-wrapping device is relatively complicated, requiring a high level of skill from the installers. Improper operation can easily lead to a decrease in the connection accuracy between the edge-wrapping device and the cabinet, affecting the overall performance of the display screen. Furthermore, during later maintenance, since the edge-wrapping device is fixed to the cabinet using multiple connectors, disassembly requires removing each connector one by one, which is a complex and time-consuming process, seriously affecting maintenance efficiency. Therefore, a quick-install edge-wrapping device for LED display cabinets is proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a quick-install edge-wrapping device for LED display cabinets, aiming to improve the problems of cumbersome installation process and difficult disassembly during later maintenance of some edge-wrapping devices in the prior art, which affects maintenance efficiency.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A quick-install edge-sealing device for an LED display cabinet includes a mounting cabinet, on the outside of which a display screen is mounted. A connecting mechanism is located inside the mounting cabinet, and the bottom of the display screen is also equipped with the mounting mechanism. The connecting mechanism includes multiple beveled fasteners, the outer sides of which are respectively engaged with the outer sides of the farthest inner side walls of the mounting cabinet. Each beveled fastener has a partially threaded bolt slidably connected inside. Each of the farthest outer sides of the mounting cabinet has a profile component 1, with multiple locking holes 1 on one outer side. Each of the near inner sides of the mounting cabinet has multiple flat fasteners, each with a partially threaded bolt 2 slidably connected inside. Each of the near outer sides of the mounting cabinet has two profile components 2, each with multiple locking holes 2 on one outer side, and a positioning component is engaged on the outer side of each profile component 2.

[0008] Through the above technical solution: the beveled fastener is snapped into the mounting box, the first half-threaded bolt slides inside it and is threadedly connected to the first locking hole of the first profile, the flat fastener is snapped into the mounting box, the second half-threaded bolt slides inside it and is threadedly connected to the second locking hole of the second profile, and the positioning component is snapped into the outside of the second profile. This achieves quick connection and positioning of the first and second profiles with the mounting box, improving the installation efficiency of the edge-wrapping device.

[0009] As a further description of the above technical solution:

[0010] The installation mechanism includes two flexible plates, the tops of which are supported on the bottom of the display screen. A support plate is fixedly connected to the bottom of the flexible plates. Multiple corner positioning blocks are fixedly connected to the outer top of the support plate. A connecting plate is fixedly connected to the closer side of each corner positioning block. Multiple positive adjustment rods are threaded into the connecting plate. An L-shaped pressure plate is rotatably connected to the closer side of each positive adjustment rod.

[0011] The above technical solution involves a flexible plate supporting the bottom of the display screen and fixing it to the support plate. An adjustment rod is installed on the corner positioning block through a connecting plate. When the adjustment rod rotates, it pushes the L-shaped pressure plate to move, thus achieving stable support and initial adjustment of the connecting mechanism and ensuring the stability of the installation.

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

[0013] Each of the corner positioning blocks is internally threaded with an angle adjusting rod, and a V-shaped pressure plate is rotatably connected to the closer side of the angle adjusting rod;

[0014] Through the above technical solution, the angle adjustment rod rotates within the angle positioning block, pushing the V-shaped pressure plate to move, which can precisely control the position of the angled plastic parts and enhance the fixing effect on the corner position of the edge-wrapping structure.

[0015] As a further description of the above technical solution:

[0016] The bottom of the L-shaped pressure plate is slidably connected to the top of the support plate, and the outside of the V-shaped pressure plate is slidably connected to the top of the flexible plate.

[0017] The above technical solution, where the L-shaped pressure plate slides on top of the support plate and the V-shaped pressure plate slides on top of the flexible plate, ensures smooth movement of the pressure plates during adjustment, improving the convenience and accuracy of the adjustment operation.

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

[0019] The positioning component includes a parallel plastic part, the outer sides of which are engaged with the closer side of the two profile parts 2, and the farther side of each of the two profile parts 2 is engaged with an angled plastic part, the outer sides of which are engaged with the outer sides of the profile part 1.

[0020] The above technical solution involves parallel plastic parts snapping between two profile parts, and angled plastic parts snapping between profile part two and profile part one, filling the gaps in the connection of the profile parts and ensuring the integrity and sealing of the edge-wrapping structure.

[0021] As a further description of the above technical solution:

[0022] The L-shaped pressure plate is externally supported on the outside of the first profile component, the L-shaped pressure plate is externally supported on the outside of the second profile component, and the V-shaped pressure plate is externally supported on the outside of the angled plastic component.

[0023] The above technical solution involves L-shaped pressure plates supporting the exterior of profile component one and profile component two, and V-shaped pressure plates supporting the exterior of the angled plastic component, further reinforcing the position of the profile component and positioning assembly to prevent them from loosening during use.

[0024] As a further description of the above technical solution:

[0025] The other end of the first half-tooth bolt is threaded into the inside of the first locking hole, and the other end of the second half-tooth bolt is threaded into the inside of the second locking hole;

[0026] Through the above technical solution, the threaded connection between the first half-threaded bolt and the first locking hole, and the second half-threaded bolt and the second locking hole, the oblique edge fixing component and the first profile component, and the flat fixing component and the second profile component are firmly fixed, ensuring the stability of the edge-wrapping structure.

[0027] As a further description of the above technical solution:

[0028] By adjusting the positive adjustment rod to push the L-shaped pressure plate to move, the second profile and the first profile are aligned with the outside of the mounting box. By adjusting the angle adjustment rod to push the V-shaped pressure plate to move, the position of the angled plastic part at the connection between the second profile and the first profile is restricted.

[0029] The above technical solution involves adjusting the positive adjustment rod to align the L-shaped pressure plate with profile part two and profile part one, and adjusting the angle adjustment rod to restrict the position of the angled plastic parts with the V-shaped pressure plate, thus ensuring the precise alignment and stable connection of each component of the edge-wrapping device and improving the reliability of the overall structure.

[0030] This utility model has the following beneficial effects:

[0031] 1. In this utility model, by snapping the first profile component onto the outer sides of the mounting box, the first half-threaded bolt slides within the inclined fixing component and is threaded into the first snapping hole of the first profile component, thereby driving the first profile component to be tightly fixed to the mounting box. At the same time, by snapping the second profile component onto the outer sides of the mounting box, the second half-threaded bolt slides within the flat fixing component and is threaded into the second snapping hole of the second profile component, thereby driving the second profile component to be stably fixed to the mounting box. This achieves the effect of quick installation, stable connection, and easy maintenance of the entire edge-wrapping device.

[0032] 2. In this utility model, with the cooperation of the corner positioning block and the connecting plate, the positive adjustment rod can be stably installed and play an adjustment role. With the cooperation of the positive adjustment rod and the support plate, the bottom of the L-shaped pressure plate slides along the top of the support plate and is precisely supported on the outside of profile part one and profile part two. With the cooperation of the corner positioning block and the flexible plate, the corner adjustment rod pushes the V-shaped pressure plate to slide along the top of the flexible plate and is stably supported on the outside of the angled plastic part. This solves the problem that the connection is prone to displacement during edge wrapping installation, affecting the integrity and sealing of the edge wrapping structure, and improves the installation quality and usage stability of the LED display cabinet edge wrapping device.

Detailed Implementation

[0044] 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.

[0045] Reference Figures 1 to 8The present invention provides an embodiment of a quick-install edge-wrapping device for an LED display cabinet, comprising a mounting cabinet 1, which is an aluminum alloy die-cast cabinet with high strength and precision. A display screen 2 is installed on the outside of the mounting cabinet 1. The display screen 2 is the core display component of the LED display screen and is responsible for displaying image and video information. Its installation stability directly affects the display effect and service life. A connecting mechanism 3 is provided inside the mounting cabinet 1, and an installation mechanism 4 is provided at the bottom of the display screen 2.

[0046] The connecting mechanism 3 includes multiple inclined fasteners 31. The inclined fasteners 31 serve as the intermediate fixing structure connecting the mounting box 1 and the profile part 33. The external parts of the multiple inclined fasteners 31 are respectively snapped into the inner far side walls of the mounting box 1. The internal parts of each inclined fastener 31 are slidably connected with a half-threaded bolt 32. The half-threaded bolt 32 connects the inclined fasteners 31 and the profile part 33, and fixes the two into one by threaded connection, thereby stably installing the profile part 33 on the outside of the mounting box 1. The outer far side of the mounting box 1 is snapped with the profile part 33. The profile part 33 serves as the edge-wrapping body on the outer far side of the mounting box 1. Through the connection with the inclined fasteners 31 and the half-threaded bolts 32, the edge-wrapping structure on both sides of the box is formed.

[0047] Multiple locking holes 34 are provided on the outer side of the profile component 33. The locking holes 34 provide threaded connection points for the semi-threaded bolts 32, so that the semi-threaded bolts 32 can stably connect the inclined fastener 31 to the profile component 33. Multiple flat fasteners 35 are locked on both sides of the interior of the mounting box 1. The flat fasteners 35 are used to connect the mounting box 1 and the profile component 37. Their exteriors are locked on both sides of the interior of the mounting box 1 to provide a mounting carrier for the semi-threaded bolts 36. The interiors of the flat fasteners 35 are slidably connected to the semi-threaded bolts 36. The semi-threaded bolts 36 connect the flat fasteners 35 and the profile component 37. The profile component 37 is fixed to both sides of the exterior of the mounting box 1 through threaded connection to ensure the integrity of the edge-wrapping structure.

[0048] Two profile parts 37 are snapped onto the outer sides of the mounting box 1. Profile parts 37 serve as the edging structure on the outer sides of the mounting box 1, forming a complete edging with profile parts 33. They also provide mounting points for the parallel plastic parts 391 and the angled plastic parts 392. Multiple locking holes 38 are provided on the outer side of profile parts 37. The locking holes 38 provide threaded connection positions for the semi-threaded bolts 36, enabling the semi-threaded bolts 36 to firmly connect the flat fixing part 35 to the profile parts 37. A positioning component 39 is snapped onto the outer side of profile parts 37. The other end of the semi-threaded bolt 32 is threaded into the inside of the locking hole 34, and the other end of the semi-threaded bolt 36 is threaded into the inside of the locking hole 38.

[0049] Specifically, the edge-wrapping device's core components include a mounting housing 1 and a display screen 2. An internal connecting mechanism 3 is provided, and a mounting mechanism 4 is located at the bottom of the display screen 2. The connecting mechanism 3 is crucial for achieving the edge-wrapping. Multiple beveled fasteners 31 are respectively engaged with the farthest two side walls inside the mounting housing 1. The internally slidingly connected semi-threaded bolts 32 are threadedly connected to the locking holes 34 on the profile 33, stably fixing the profile 33 engaged with the farthest two sides outside the mounting housing 1, forming the main edge-wrapping body on both sides of the housing. Simultaneously, multiple flat fasteners 35 engaged with the nearth two sides inside the mounting housing 1 have internally slidingly connected semi-threaded bolts 36, threadedly connected to the locking holes 38 on the profile 37, fixing the two profiles 37 engaged with the nearth two sides outside the mounting housing 1, forming a complete edge-wrapping with the profile 33. The positioning component 39 engaged with the outside of the profile 37 further ensures the stability of the connection.

[0050] The positioning component 39 includes a parallel plastic part 391, which connects the two profile parts 37 to the closer side, ensuring that they remain parallel during installation and preventing misalignment. It also fills the gap between them. The outer sides of the parallel plastic part 391 are snapped onto the closer side of the two profile parts 37. The far side of each profile part 37 is snapped onto an angled plastic part 392, which connects the profile part 37 to the connection point of the profile part 33. The angled structure adapts to the connection angle of the two, achieving corner sealing and positioning, and ensuring the integrity of the edge. The outer sides of the angled plastic part 392 are snapped onto the outer sides of the profile part 33.

[0051] Specifically, the positioning component 39 includes a parallel plastic part 391 and an angled plastic part 392. The outer sides of the parallel plastic part 391 are engaged with the closer side of the two profile parts 37, which can connect the two and ensure the parallel state during installation, prevent displacement and fill gaps. The far side of the two profile parts 37 is engaged with the angled plastic part 392, which is engaged with the outer sides of the profile part 33, and can connect the connection between the profile part 37 and the profile part 33. By adapting the connection angle, the corner sealing and positioning are achieved, ensuring the integrity of the edge wrapping.

[0052] Reference Figure 1 and Figure 9 The installation mechanism 4 includes two flexible plates 41. The flexible plates 41 support the bottom of the screen display 2 and use their own flexibility to buffer the pressure and vibration of the screen display 2, protecting the screen display 2 from hard impacts. The top of the two flexible plates 41 is supported on the bottom of the screen display 2. The bottom of the flexible plates 41 is fixedly connected to a support plate 42. The support plate 42 supports the flexible plates 41 and the corner positioning block 43, distributing the weight of the screen display 2 evenly and ensuring the stability of the overall installation mechanism 4.

[0053] Multiple corner positioning blocks 43 are fixedly connected to the top outer side of the support plate 42. The corner positioning blocks 43 provide the installation base for the connecting plate 44 and the corner adjusting rod 47, and at the same time play an auxiliary positioning role for the corner position of the screen display 2. The connecting plate 44 is fixedly connected to the closer side of the multiple corner positioning blocks 43. The connecting plate 44 connects the corner positioning blocks 43 and the positive adjusting rod 45, providing an installation carrier for the positive adjusting rod 45, and transmitting the adjusting force of the positive adjusting rod 45 to the L-shaped pressure plate 46. Multiple positive adjusting rods 45 are connected to the internal threads of the connecting plate 44. The positive adjusting rods 45 push the L-shaped pressure plate 46 to move through the rotation of the threads, thereby realizing the position adjustment of profile part 1 33 and profile part 2 37, ensuring that they are aligned with the outside of the mounting box 1.

[0054] An L-shaped pressure plate 46 is rotatably connected to the side of the positive adjustment rod 45. The L-shaped pressure plate 46 moves under the push of the positive adjustment rod 45 and is supported on the outside of profile part 1 33 and profile part 2 37. An angle adjustment rod 47 is threadedly connected to the inside of the corner positioning block 43. The angle adjustment rod 47 pushes the V-shaped pressure plate 48 to move by rotating, limiting the position of the angled plastic part 392 at the connection of profile part 2 37 and profile part 1 33. A V-shaped pressure plate 48 is rotatably connected to the side of the angle adjustment rod 47. The V-shaped pressure plate 48 moves under the push of the angle adjustment rod 47 and is supported on the outside of the angled plastic part 392. The V-shaped structure matches the angle of the angled plastic part 392, limiting its position at the connection of profile part 2 37 and profile part 1 33. The bottom of the L-shaped pressure plate 46 is slidably connected to the top of the support plate 42, and the outside of the V-shaped pressure plate 48 is slidably connected to the top of the flexible plate 41.

[0055] The external support of the L-shaped pressure plate 46 is on the outside of the profile part 33, the external support of the L-shaped pressure plate 46 is on the outside of the profile part 37, and the external support of the V-shaped pressure plate 48 is on the outside of the angled plastic part 392. By adjusting the positive adjustment rod 45, the L-shaped pressure plate 46 is moved to align the profile part 37 and the profile part 33 on the outside of the mounting box 1. By adjusting the angle adjustment rod 47, the V-shaped pressure plate 48 is moved to restrict the position of the angled plastic part 392 at the connection between the profile part 37 and the profile part 33.

[0056] Specifically, the mounting mechanism 4 is supported by two flexible plates 41 at the top, which buffer pressure and vibration. The support plate 42 fixedly connected to the bottom can evenly distribute the weight of the display 2. Multiple corner positioning blocks 43 fixed on the outer side of the top of the support plate 42 can assist in positioning the corners of the display 2. When the positive adjustment rod 45 connected to the connecting plate 44 fixed to the closer side of the corner positioning block 43 rotates, it can push the L-shaped pressure plate 46 connected to the closer side to move, so that the L-shaped pressure plate 46 is supported on the outside of the profile part 33 and the profile part 37, and the position is adjusted to ensure alignment with the outside of the mounting box 1. When the corner adjustment rod 47 connected to the corner positioning block 43 rotates, it pushes the V-shaped pressure plate 48 connected to the closer side to move, so that the V-shaped pressure plate 48 is supported on the outside of the angled plastic part 392, limiting its position at the connection. The bottom of the L-shaped pressure plate 46 and the outside of the V-shaped pressure plate 48 are slidably connected to the top of the support plate 42 and the top of the flexible plate 41, respectively.

[0057] Working principle: During installation, the mounting box 1 is first used as a base. Multiple beveled fasteners 31 are snapped into the far side walls inside, and flat fasteners 35 are snapped into the near side walls inside. Then, the parallel plastic parts 391 in the positioning assembly 39 are snapped into the near side of the two profile parts 37, and the beveled plastic parts 392 are snapped into the far side of the profile part 37 and the outer sides of the profile part 33, thus fixing the connection between the profile part 33 and the profile part 37. Then, clip the profile part 33 to the far sides of the outside of the mounting box 1, so that the half-threaded bolt 32 slides in the inclined fixing part 31 and is threaded into the clipping hole 34 of the profile part 33 to fix the profile part 33. At the same time, clip the profile part 37 to the near sides of the outside of the mounting box 1, so that the half-threaded bolt 36 slides in the flat fixing part 35 and is threaded into the clipping hole 38 of the profile part 37 to fix the profile part 37.

[0058] An installation mechanism 4 is set at the bottom of the display screen 2, so that the top of the two flexible plates 41 supports the display screen 2 and the bottom is fixed to the support plate 42. The corner positioning block 43 on the outer side of the top of the support plate 42 is equipped with a positive adjustment rod 45 through the connecting plate 44. The positive adjustment rod 45 pushes the L-shaped pressure plate 46, which is slidably connected to the top of the support plate 42, to move, so that it is supported outside the profile part 1 33 and profile part 2 37. At the same time, the corner adjustment rod 47 on the corner positioning block 43 pushes the V-shaped pressure plate 48, which is slidably connected to the top of the flexible plate 41, to move, so that it is supported outside the angled plastic part 392, restricting the position of the angled plastic part 392 at the connection between profile part 2 37 and profile part 1 33.

[0059] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
