Description

Technical Field

[0001] This utility model belongs to the field of splicing LED display technology, and in particular relates to a splicing LED display that is easy to maintain. Background Technology

[0002] A modular LED display is a large-size display system seamlessly assembled from multiple independent LED display units (cabinets). Its core lies in using physical splicing and software control to connect these units into a visually coherent and scalable giant display screen. Each unit is a complete LED module, containing densely packed light-emitting diodes (LEDs) as pixels. Precise splicing technology ensures minimal physical gaps between units. A professional control system drives the display, ensuring seamless and synchronized display across units, providing high brightness, high contrast, and wide viewing angles for full-screen images or videos. It is particularly suitable for large public spaces, control rooms, stage backdrops, and other scenarios requiring ultra-large size, flexible customization, and stunning visual effects.

[0003] When a component of a modular monitor malfunctions, it needs to be repaired or replaced. The current method requires removing the entire modular monitor from the wall and then unscrewing multiple bolts at the back of the monitor to remove the faulty monitor. The entire process is time-consuming and labor-intensive, which is not conducive to efficient monitor repair.

[0004] To address the aforementioned issues, this application proposes an easy-to-maintain splicing LED display. Utility Model Content

[0005] The purpose of this invention is to provide an easy-to-maintain splicing LED display, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an easy-to-maintain splicing LED display, comprising a wall-mounted box and several individual displays located inside the wall-mounted box. The wall-mounted box is provided with a linkage frame that moves back and forth via an adjustment mechanism. The linkage frame has multiple horizontally arranged units, each of which is simultaneously connected to multiple vertically arranged individual displays. The forward movement of the linkage frame causes the individual displays to detach from the front of the wall-mounted box. A mounting bracket is fixed on the linkage frame, and a hanging bracket is fixed on the individual display, which is horizontally inserted into the mounting bracket along its side. A locking hole is provided at the connection between the linkage frame, the mounting bracket, and the hanging bracket along the direction of movement of the linkage frame. A locking pin is fixed to the wall-mounted box via a fixing plate and inserted into the locking hole.

[0008] Furthermore, an inner support plate and a guide plate are formed on the upper inner side of the bracket, and the inner support plate and the guide plate are fixedly installed.

[0009] Furthermore, a baffle is fixed at the end of the linkage frame away from the guide plate.

[0010] Furthermore, the adjustment mechanism includes a bidirectional lead screw that rotates vertically inside the wall-mounted box and two internal threaded sleeves that are threaded to both ends of the bidirectional lead screw. The upper and lower internal threaded sleeves are each provided with a hinged connecting rod between them and the linkage frame.

[0011] Furthermore, the bidirectional lead screw has two parts arranged on the left and right, and the two bidirectional lead screws are synchronously connected by a synchronizing rod. One of the bidirectional lead screws has a screw wheel fixed at its bottom that extends through to the outside of the lower end of the wall-mounted box.

[0012] Furthermore, a guide sleeve corresponding to the lock hole is fixed on the side of the linkage frame near the wall-mounted box, and the guide sleeve is coaxially corresponding to the lock pin.

[0013] This utility model has the following beneficial effects:

[0014] This utility model involves simultaneously installing a row of individual displays with a linkage frame, and then moving the linkage frame back and forth on the wall-mounted box through the cooperation of a two-way screw, an internal threaded sleeve, and a connecting rod. When the linkage frame moves forward, it causes the corresponding row of two-way screws to be misaligned with the other displays, making it easy to remove the individual displays from the linkage frame; when the linkage frame moves backward, it neatly arranges all the displays without removing the entire display, thus facilitating installation, disassembly, and maintenance.

[0015] This utility model features a locking pin and a locking hole that work together while the linkage frame and the single display move back and forth. Then, through the lateral sliding cooperation between the hanger and the mounting base, the single display can be conveniently and stably installed on the linkage frame.

[0016] This utility model, by setting an inner support plate and a guide plate on the hanging seat to cooperate with the hanging frame, allows the front end of the hanging seat to quickly connect with the hanging frame, which is convenient for assembly. The hanging frame automatically cooperates with the inner support plate along the hanging seat under the action of the guide plate, so as to achieve the purpose of automatic alignment of the single display on the linkage frame, which facilitates the installation work.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0030] 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.

[0031] In the description of this utility model, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inner", "around" and other terms indicating orientation or positional relationship are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0032] Please see Figures 1-9 As shown, this utility model is an easy-to-maintain splicing LED display, including a wall-mounted box 1 and several individual displays 3 located inside the wall-mounted box 1. The wall-mounted box 1 is provided with a linkage frame 2 that moves back and forth through an adjustment mechanism. The linkage frame 2 has multiple horizontally arranged individual displays 3. Each linkage frame 2 is simultaneously connected to multiple vertically arranged individual displays 3. The forward movement of the linkage frame 2 causes the individual displays 3 to detach from the front of the wall-mounted box 1. A mounting bracket 21 is fixed on the linkage frame 2. A hanging bracket 31 is fixed on the individual displays 3 and is horizontally inserted into the mounting bracket 21 along the side. A locking hole 22 is provided at the connection of the linkage frame 2, the mounting bracket 21, and the hanging bracket 31 along the direction of movement of the linkage frame 2. A locking pin 111 is fixed on the wall-mounted box 1 through a fixing plate 11 and is inserted into the locking hole 22.

[0033] Furthermore, an inner support plate 211 and a guide plate 212 are formed on the upper inner side of the hanger 21. The inner support plate 211 and the guide plate 212 are fixedly installed. In this embodiment, when the hanger 31 and the leftmost side of the hanger 21 are connected, there is still a large space for front and back movement, which facilitates the connection between the two. The presence of the guide plate 212 tightens the hanger 31 on the hanger 21 backward, so that the two fit tightly together and ensure a reliable connection of the structure.

[0034] Furthermore, a baffle 213 is fixed at the end of the linkage frame 2 away from the guide plate 212. The baffle 213 serves as a blind positioning function. In practical use, the single display 3 cannot directly observe the specific position of the hanger 31 in the hanger 21 during installation. When the hanger 31 abuts against the baffle 213, it indicates that the hanger 31 is installed in place, thus achieving a blind positioning function.

[0035] Furthermore, the adjustment mechanism includes a bidirectional lead screw 4 that rotates vertically inside the wall-mounted box 1 and two internal threaded sleeves 41 that are threaded to both ends of the bidirectional lead screw 4. The upper and lower internal threaded sleeves 41 are each provided with a hinged connecting rod 42 between them and the linkage frame 2.

[0036] In this embodiment, the vertically arranged internal threaded sleeve 41 has a better vertical compressive strength, avoiding drooping and tilting after the linkage frame 2 and the single display 3 are extended, thus ensuring the stability of the mechanism.

[0037] Furthermore, to ensure the stable operation of the linkage frame 2 and the single display 3, two bidirectional lead screws 4 are arranged on the left and right sides. The two bidirectional lead screws 4 are synchronously connected by a synchronizing rod 43. One of the bidirectional lead screws 4 has a screw wheel 44 fixed at its bottom, which extends to the outside of the lower end of the wall-mounted box 1. Specifically, the synchronizing rod 43 is connected to the two bidirectional lead screws 4 through a bevel gear pair. Under the action of the bevel gear pair and the bidirectional lead screws 4, when the screw wheel 44 rotates, the two bidirectional lead screws 4 rotate synchronously.

[0038] Furthermore, a guide sleeve 23 corresponding to the lock hole 22 is fixed on the side of the linkage frame 2 near the wall-mounted box 1. The guide sleeve 23 is coaxial with the lock pin 111. The part where the guide sleeve 23 and the lock pin 111 meet is chamfered. The chamfer serves to guide the insertion of the lock pin 111 and the lock hole 22, ensuring accurate insertion.

[0039] Understandably, this utility model uses a linkage frame and a two-way lead screw mechanism to drive the entire row of individual monitors to move back and forth on the wall-mounted box: when moving forward, the monitors are staggered for easy removal of individual units; when moving backward, they are neatly arranged, avoiding overall disassembly and facilitating maintenance. Simultaneously, the use of locking pins and locking holes, combined with the lateral sliding of the bracket on the mounting base, enables convenient and stable installation of individual monitors. The design of the inner support plate and guide plate on the mounting base allows the bracket to quickly assemble and automatically align, further simplifying the installation process.

[0040] One specific application of this embodiment is as follows: Figure 1 The single monitors 3 on the left and right sides shown are in the installation state, and at the same time, the corresponding Figure 4 , Figure 5 The state shown; Figure 1 The single monitor 3 in the middle position is in a protruding state, and at the same time, it corresponds to... Figure 3 The state shown;

[0041] When the single display 3 needs maintenance, turn the corresponding bottom screw wheel 44. After the screw wheel 44 rotates, it drives the two double-acting screws 4 to rotate synchronously through the synchronizing rod 43. This causes the two internally threaded sleeves 41 arranged vertically to move closer to each other. Then, under the action of the connecting rod 42, the linkage frame 2 and the single display 3 are pushed forward. During the pushing process, the locking pin 111 disengages from the locking hole 22 until it is pushed out to the position. Figure 1-2 The state of the single monitor 3 shown in the middle is as follows: Hold the single monitor 3 to be repaired and move it horizontally to the left. The bracket 31 will fall off along the side of the bracket 21. Disconnect all the connectors on the single monitor 3 and take out the single monitor 3.

[0042] Installation of single monitor 3: Align the single monitor 3 horizontally with the installation position and place it on the left side. Place the bracket 31 on the leftmost side of the mounting base 21. Then slide the single monitor 3 to the right. Under the action of the guide plate 212, move the bracket 31 to the inside of the inner support plate 211 and abut against the baffle 213. At this time, the mounting base 21 and the bracket 31 are in a fully fitted state. The locking hole 22 on the bracket 31 and the linkage frame 2 are coaxially aligned. Drive the bidirectional screw 4 in the opposite direction. The linkage frame 2 and the single monitor 3 move towards the wall-mounted box 1. The locking pin 111 passes through the linkage frame 2, the mounting base 21, the bracket 31, and the inner support plate 211, thereby completing the final locking of the single monitor 3 on the linkage frame 2.
