[0008] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0009] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "multiple" means two or more, unless otherwise explicitly specified.

[0010] For ease of description of the first, second, and third directions in the embodiments of this application, the first direction is the left-right direction in the figures, the second direction is the front-back direction in the figures, and the third direction is the up-down direction in the figures. The x-axis arrow direction is referred to as the "right" direction, the y-axis arrow direction as the "up" direction, and the z-axis arrow direction as the "back" direction, but these are not the sole limitations in the actual application of this application.

[0011] like Figures 1-5 as well as Figure 10As shown, this embodiment provides an LED display screen 1, which includes a main body 10, a support component 20, an LED display component 30, an electrical control component 40, and a second connecting component 60. The main body 10 is used for fixed installation with a building; the support component 20 is installed on the main body 10; the LED display component 30 is installed on the support component 20, and the LED display component 30 can be fixed or separated from the support component 20; the electrical control component 40 is used to supply power to the LED display component 30 and control the LED display component 30 to display information; the second connecting component 60 is used to control the fixing or separation of the LED display component 30 from the support component 20; when the LED display component 30 is fixed to the support component 20 via the second connecting component 60, the electrical control component 40 can supply power to the LED display component 30 and control the LED display component 30 to display information. The second connecting component 60 enables the removal of the LED display component 30, facilitating maintenance work on the LED display component 30.

[0012] like Figure 1 As shown, optionally, the electronic control component 40 includes a power cord, a circuit board, and electronic devices disposed on the circuit board.

[0013] like Figures 1-2 As shown, optionally, the carrier component 20 includes a first frame 21 and a circuit support 22; the first frame 21 is used for mounting to the main body 10; the circuit support 22 connects the circuit and supports the LED display component 30.

[0014] like Figures 1-5 As shown, optionally, a first connecting component 50 is also included, which is used for the installation and separation of the support component 20 from the main body 10. The assembly and disassembly of the support component 20 from the main body 10 facilitates the installation and subsequent maintenance of the LED display component 30.

[0015] like Figures 1-5 As shown, optionally, the first connecting component 50 further includes a sliding component 51 and a limiting component 52; the bearing component 20 and the main body 10 are installed or separated via the sliding component 51; the limiting component 52 is used to restrict the stable movement of the sliding component 51. Through the cooperative use of the sliding component 51 and the limiting component 52, the stable installation of the bearing component 20 and the main body 10 can be ensured, preventing damage from impacts caused by shaking.

[0016] like Figures 4-5 As shown, optionally, the sliding assembly 51 includes a groove 51a disposed on the main body 10 and a slider 51b disposed on the support assembly 20. The slider 51b is disposed on the first frame 21, and slides within the groove 51a to install or separate the support assembly 20 from the main body 10. Installation is performed by sliding the slider 51b on the slide rail, preventing it from falling off during installation and causing danger or damage to the support assembly 20.

[0017] like Figures 4-5 As shown, optionally, the limiting component 52 includes springs and moving members 52b disposed on both sides of the slide groove 51a, and a rotating member 52c disposed on the sliding member 51b; the springs provide a force to the moving members 52b to move towards the center of the slide groove 51a, and the rotating member 52c is positioned between the two moving members 52b. The rotating member 52c and the moving members 52b prevent the sliding member 51b from contacting the slide groove 51a. By utilizing the cooperation of the moving members 52b and the rotating member 52c, the contact area of ​​movement is reduced, and friction is further reduced under the action of rotation. This prevents the problem of the bearing component 20 being difficult to remove or insert from the main body 10 during operation, while also reducing wear and preventing noise.

[0018] Optionally, the rotating component 52c is a wheel with its outer edge recessed inward, and the movable component 52b has a hemispherical cross-section on the side near the rotating component 52c, with the side of the movable component 52b near the rotating component 52c positioned in the recess. By placing the movable component 52b within the recess of the rotating component 52c, the supporting assembly 20 can remain attached to the main body 10, ensuring sliding stability.

[0019] The first connecting component 50 also includes a positioning component 53; the positioning component 53 is used to ensure precise installation of the main body 10 and the support component 20. The positioning component 53 is used to fix the support component 20 after installation, preventing misalignment during use that could affect the display of the LED display component 30.

[0020] like Figure 1 As shown, optionally, the positioning component 53 includes a positioning block 53a, which is disposed on the main body 10. When the carrier component 20 is installed with the main body 10, the positioning component can position the carrier component 20, thereby positioning the first connector 70. The positioning of the positioning block 53a ensures the accuracy of the installation and prevents installation deviations.

[0021] like Figures 11-15 As shown, in one embodiment, the first connecting component 50 includes a rotating component 5a and a locking component 5b; the rotating component 5a enables the carrier component 20 to rotate, thereby switching between a vertical placement state and a horizontal placement state, facilitating the installation or removal of the carrier component 20; the locking component 5b can restrict the rotation of the rotating component 5a when the carrier component 20 is placed horizontally, that is, when the rotating component 5a is rotated to a horizontal placement, the locking component 5b can restrict the rotation of the rotating component 5a, thereby facilitating the installation or removal of the carrier component 20.

[0022] like Figures 11-15As shown, optionally, the rotating assembly 5a includes a drive unit 5a1 and a support frame 5a2. The upper side of the support frame 5a2 is rotatably connected to the upper side of the main body. The drive unit 5a1 is used to drive the upper side of the support frame 5a2 to rotate around the rotatable connection position. By driving the support frame 5a2 to rotate via the drive unit 5a1, the support frame 5a2 can be switched between vertical and horizontal placement, thereby facilitating the installation or removal of the load-bearing assembly 20.

[0023] like Figures 11-14 As shown, optionally, the drive unit 5a1 includes a first rotating shaft 511, a first drive member 512, and a second drive member 513 disposed on the main body; the support frame 5a2 can drive the first rotating shaft 511 to rotate via the first drive member 512, and the first rotating shaft 511 drives the support frame 5a2 to rotate via the second drive member 513. Through the conversion from the support frame 5a2 to the first rotating shaft 511 and then back to the support frame 5a2, the driving force required for rotation can be reduced, and the driving difficulty can be reduced.

[0024] like Figures 11-14 As shown, optionally, the first driving component 512 includes a first gear 12n and a first rack 12m. The first gear 12n is disposed on the first rotating shaft 511, and the first rack 12m is disposed on the support frame 5a2. The movement of the first rack 12m can drive the first rotating shaft 511 to rotate via the first gear 12n. Through the cooperation of the first gear 12n and the first rack 12m, the stability during driving can be effectively guaranteed.

[0025] like Figures 11-15 As shown, optionally, the second driving component 513 includes a second gear 13n, a third gear 13m, and an internal gear ring 13x. The second gear 13n is located on the first rotating shaft 511, the gear ring is located on the support frame 5a2, and the third gear 13m is located between the second gear 13n and the internal gear ring 13x. The second gear 13n, the third gear 13m, and the internal gear ring 13x constitute a planetary gear set. The first rotating shaft 511 drives the internal gear ring 13x to rotate via the second gear 13n and the third gear 13m, thereby driving the support frame 5a2 to rotate. This reduces the force required for the first rotating shaft 511 to drive the support frame 5a2 to rotate, making it easier to install and disassemble the load-bearing component 20.

[0026] like Figures 11-12 , Figure 15As shown, optionally, the locking assembly 5b includes a slide rod 5b1, a push block 5b2, a fourth locking groove 5b3, and a fourth elastic member 5b4. The slide rod 5b1 is located on both sides of the support frame 5a2. The push block 5b2 is fixed on the side of the slide rod 5b1 away from the first rotating shaft 511. The fourth elastic member 5b4 can drive the slide rod 5b1 to move closer to the side of the first rotating shaft 511. The fourth locking groove 5b3 is located on the main body 10. When the support frame 5a2 is rotated to a horizontal position, the slide rod 5b1 is fixed in the fourth locking groove 5b3 under the action of the fourth elastic member 5b4, so that the support frame 5a2 is fixed in the horizontal position. When it is necessary to release the slide bar 5b1, that is, when the bearing assembly 20 is installed with the support frame 5a2, the bearing assembly 20 will push the push block 5b2 to move away from the first rotating shaft 511. Then the slide bar 5b1 will disengage from the fourth slot 5b3. The first rotating shaft 511 will then be able to rotate the support frame 5a2 to a vertical position under the action of the first rack 12m.

[0027] like Figure 13 As shown, optionally, the bearing assembly 20 is provided with a first stop 5c, and the first rotating shaft 511 is provided with a second stop 5d. When the first rack 12m disengages from the first gear 12n, the slide rod 5b1 is positioned directly opposite the fourth slot 5b3, that is, the slide rod 5b1 can be inserted into the fourth slot 5b3. When the first rack 12m disengages from the first gear 12n, the first stop 5c and the second stop 5d contact each other to block the rotation of the first rotating shaft 511, preventing the slide rod 5b1 from not corresponding to the fourth slot 5b3 after the first rack 12m disengages from the first gear 12n, thus preventing the support frame 5a2 from being fixed.

[0028] like Figures 11-12 , Figure 15 As shown, optionally, a third positioning element 5f and a positioning hole 5g are also included. The third positioning element 5f is installed on the side of the push block 5b2 away from the first rotating shaft 511, and the positioning hole 5g is located on the lower side of the main body. After the bearing assembly 20 pushes the push block 5b2 to move away from the first rotating shaft 511 to release the fixation, the bearing assembly 20 will continue to push the push block 5b2 to move away from the first rotating shaft 511 until the support frame 5a2 is rotated to a vertical position. Then, the bearing assembly 20 will push the push block 5b2 again to insert the third positioning element 5f into the positioning hole 5g. Under the action of the third positioning element 5f, the stability of the bearing assembly 20 after it is rotated to a vertical position can be ensured.

[0029] Optionally, the lower end of the third positioning element 5f is tapered to facilitate insertion into the positioning hole 5g for positioning.

[0030] like Figures 11-12 , Figures 14-15As shown, optionally, the first connecting assembly 50 further includes a sliding mechanism 5h, which is used for installing or separating the load-bearing assembly 20 from the support frame 5a2. The sliding mechanism 5h ensures stable installation of the load-bearing assembly 20 and the support frame 5a2.

[0031] Optionally, the sliding mechanism 5h includes a sliding groove 5h2 and a sliding protrusion 5h1. The sliding groove 5h2 is located on the support frame 5a2 and the bearing component 20. The bearing component 20 slides on the support frame 5a2 via the sliding groove 5h2 and the sliding protrusion 5h1, ensuring the stability of the installation.

[0032] Optionally, after the load-bearing component 20 is installed with the support frame 5a2, the sliding groove 5h2 and the sliding protrusion 5h1 are arranged vertically. During the installation or removal of the load-bearing component 20 via the sliding groove 5h2 and the sliding protrusion 5h1, the load-bearing component 20 drives the first rotating shaft 511 to rotate via the first rack 12m and the first gear 12n. The first rotating shaft 511 drives the support frame 5a2 to rotate via the planetary gear set, ensuring stable operation.

[0033] The implementation process of rotating the support frame 5a2: When the bearing assembly 20 is removed, the bearing assembly 20 moves upward along the sliding groove 5h2 via the sliding protrusion 5h1. After the bearing assembly 20 moves upward, the fourth elastic element 5b4 first pulls upward to disengage from the positioning hole 5g, and continues to pull the bearing assembly 20 upward. The first rack 12m on the bearing assembly 20 drives the first rotating shaft 511 to rotate via the first gear 12n. The first rotating shaft 511 drives the support frame 5a2 to rotate via the planetary gear set until the support frame 5a2 rotates to the horizontal position. The rotation of the support frame 5a2 also causes the bearing assembly 20 to rotate to the horizontal position. After the first rack 12m separates from the first gear 12n, the slide rod 5b1 is placed in the fourth slot 5b3 to fix the support frame 5a2. Then the bearing assembly 20 can be taken out. During the installation of the bearing assembly 20, the sliding protrusion 5h1 on the bearing assembly 20 is first placed in the sliding groove 5h2, and then the bearing assembly 20 is pushed to move along the sliding groove 5h2 until the bearing assembly 20 contacts the push block 5b2 and pushes the push block 5b2 to move. The slide rod 5b1 separates from the fourth slot 5b3. Then, the first rack 12m meshes with the first gear 12n. The bearing assembly 20 drives the first rotating shaft 511 to rotate through the first rack 12m and the first gear 12n. The first rotating shaft 511 drives the support frame 5a2 to rotate again through the planetary gear set until the support frame 5a2 is rotated to a vertical position. Finally, the bearing assembly 20 pushes the push block 5b2 to insert the third positioning member 5f into the positioning hole 5g, and the bearing assembly 20 is fixed.

[0034] like Figure 3As shown, optionally, a gripping part 2 is also included. The gripping part 2 is disposed on the top of the support assembly 20, and the gripping part 2 can be fixed or separated from the support assembly 20. When the gripping part 2 is fixed to the support assembly 20, it facilitates gripping operations during the installation or separation of the support assembly 20. When the gripping part 2 is separated from the support assembly 20, it can prevent the support assembly 20 from being obstructed after installation.

[0035] Preferably, the gripping part 2 and the bearing component 20 are connected by threads.

[0036] like Figures 2-3 As shown, optionally, the second connecting component 60 includes a limiting hole 61 provided in the carrier component 20 and a limiting member 62 provided in the LED display component 30; the limiting member 62 can be rotatably placed in the limiting hole 61 to fix the carrier component 20 and the LED display component 30, and the limiting member 62 can be separated from the LED display component 30 after being rotated in the opposite direction. The cooperation of the limiting hole 61 and the limiting member 62 makes installation and disassembly more convenient.

[0037] Optionally, the limiting component 62 includes a bolt and a nut; the bolt is installed on the LED display assembly 30, and after passing through the limiting hole 61, the nut secures the LED display assembly 30 to the supporting component 20. Using a bolt and nut combination for fixing makes the fixation more stable and prevents accidental detachment of the LED display assembly 30.

[0038] Preferably, the nut is a ram's horn nut. The choice of ram's horn nut makes disassembly more convenient and does not require the use of external tools.

[0039] like Figures 2-3 As shown, optionally, the limiting member 62 includes a round rod that rotates around the LED display assembly 30 and an elongated stop 621 located on the round rod away from the LED display assembly 30; the limiting hole 61 is an elongated hole; when the LED display assembly 30 approaches the support assembly 20, the stop 621 passes through the limiting hole 61, and after rotating the round rod, the stop 621 engages with the support assembly 20, thus fixing the LED display assembly 30 to the support assembly 20. By utilizing the cooperation of the elongated hole and the elongated stop 621, the LED display assembly 30 can be fixed to the support assembly 20 by rotating the elongated stop 621 a certain angle after it passes through the elongated hole, making the operation simple and convenient.

[0040] like Figures 1-3As shown, optionally, a first connector 70 and a second connector 80 are also included; the first connector 70 is used to connect the electronic control component 40 to the carrier component 20; the second connector 80 is used to connect the carrier component 20 to the LED display component 30; when the first connector 70 and the second connector 80 are connected respectively, the electronic control component 40 can control the LED display component 30 to display information. Multiple connections via connectors allow for installation and fixation in different positions, while also facilitating disassembly during maintenance or repair.

[0041] Optionally, both the first connector 70 and the second connector 80 include a connector head a1 and a power supply port a2; the connector head a1 can be inserted into the power supply port a2. The use of the connector head a1 and the power supply port a2 enables quick assembly and disassembly, reducing operational difficulty.

[0042] like Figure 1 As shown, optionally, it also includes a housing 90; the housing 90 is located on the upper side of the supporting component 20, the electrical control component 40 is located inside the housing 90, and an opening is provided on the lower side of the housing 90, with the first connector 70 located at the opening. By placing the electrical control component 40 inside the housing 90, rainwater intrusion can be prevented, and the opening facilitates installation by allowing the first connector 70 to connect.

[0043] Optionally, the lower box 91 is connected to the main body 10 by bolts or by sliding connection via a groove.

[0044] Optionally, a seal is also provided on the carrier assembly 20. When the first connector 70 is connected, the opening on the housing 90 is blocked, and the seal prevents the first connector 70 from communicating with the outside of the housing 90. The seal design ensures that there is no water leakage at the connection point after the carrier assembly 20 and the main body 10 are installed, preventing moisture from entering and affecting information transmission and power supply.

[0045] Optionally, the power supply port a2 is located in the electrical control component 40, and the connector a1 is located in the bearing component 20.

[0046] Optionally, the power supply port a2 is located on the carrier component 20, and the connector a1 is located on the LED display component 30.

[0047] like Figures 6-9 As shown, optionally, the second connecting component 60 includes a limiting mechanism 6a and a fixing mechanism 6b; the limiting mechanism 6a is used to prevent the LED display component 30 from automatically detaching from the carrier component 20, and the limiting mechanism 6a can prevent the LED display component 30 from automatically detaching after the fixing mechanism 6b accidentally releases the fixing from the carrier component 20, thus preventing the LED display component 30 from being bumped or damaged; the fixing mechanism 6b is used to fix the LED display component 30 to the carrier component 20 to ensure the normal operation of the LED display component 30.

[0048] like Figures 1-5 As shown, optionally, the limiting mechanism 6a includes a limiting block 6a1 provided on the LED display component 30 and a limiting hole 6a2 provided on the support component 20. When the limiting block 6a1 is placed in the limiting hole 6a2, the limiting hole 6a2 prevents the limiting block from disengaging, thereby preventing the LED display component 30 from disengaging.

[0049] like Figures 1-5 As shown, optionally, the limiting block 6a1 is cylindrical and the limiting hole 6a2 is circular. By making the limiting block 6a1 cylindrical and the limiting hole 6a2 circular, it is easier to align the LED display component 30 with the carrier component 20 when fixing them, making the operation simple and convenient.

[0050] Optionally, the limiting block 6a1 is provided with a slot a11, and the limiting hole 6a2 is provided with a block a22. When the limiting block 6a1 is rotated so that the block a22 is placed in the slot a11, the block a22 is separated from the limiting hole 6a2 by the limiting block of the slot a11.

[0051] like Figures 1-5 As shown, optionally, the slot a11 includes a first slot 11a located on the outer edge of the limiting block. The first slot 11a is arranged radially along the limiting block 6a1. A second slot 11b and a third slot 11c are respectively provided at both ends of the first slot 11a. The second slot 11b extends from the first slot 11a toward the bearing component 20 and passes through the side of the limiting block 6a1 closest to the bearing component 20. The third slot 11c extends from the first slot 11a toward the side away from the bearing component 20. The first slot 11a prevents the limiting block 6a1 from easily disengaging from the limiting hole 6a2. The second slot 11b and the third slot 11c can make way for the movement of the locking block a22, allowing the limiting block 6a1 to be installed or disengaged from the limiting hole 6a2.

[0052] Optionally, the included angle of the first slot 11a is between 30 and 180 degrees.

[0053] Preferably, the included angle of the first slot 11a is 90 degrees.

[0054] like Figures 1-5 As shown, optionally, the fixing mechanism 6b includes a first positioning member 6b1 and a second positioning member 6b2. The first positioning member 6b1 is disposed on the LED display component 30 and the second positioning member 6b2 is disposed on the support component 20. When the first positioning member 6b1 moves closer to the second positioning member 6b2 and is fixed, the LED display component 30 and the support component 20 can be fixed.

[0055] Optionally, the first positioning element 6b1 is a strong magnet, which may be a neodymium iron boron magnet; Optionally, the second positioning element 6b2 is a strong magnet, which can be a neodymium iron boron magnet; like Figures 1-5 As shown, optionally, the second positioning member 6b2 can rotate. When the second positioning member 6b2 rotates to the opposite magnetic pole to the first positioning member 6b1, the first positioning member 6b1 and the second positioning member 6b2 are attracted and fixed. When the second positioning member 6b2 rotates to the same magnetic pole as the first positioning member 6b1, the repulsive force of the second positioning member 6b2 causes the first positioning member 6b1 to move away from the second positioning member 6b2, and the first positioning member 6b1 can separate from the second positioning member 6b2.

[0056] like Figures 1-5 As shown, optionally, the second positioning member 6b2 is spherical or ellipsoidal, which can prevent the first positioning member 6b1 and the second positioning member 6b2 from detaching under the attraction of a strong magnet, and can also reduce rotational resistance during rotation, thus ensuring the stability of the second positioning member 6b2 during rotation.

[0057] Optionally, the bearing assembly 20 is provided with a second rotating shaft 6c, and a second positioning member 6b2 is installed on the second rotating shaft 6c, and the axis of the second rotating shaft 6c passes through the center of the second positioning member 6b2; when the second rotating shaft 6c rotates, it drives the second positioning member 6b2 to rotate.

[0058] Optionally, a drive wheel 6d is mounted on the second rotating shaft 6c, and a drive component 6e is provided on the bearing assembly 20, which can drive the drive wheel 6d to rotate.

[0059] Preferably, the drive wheel 6d is a gear; the drive component 6e can be a rack.

[0060] Preferably, the drive wheel 6d is a friction wheel; the drive component 6e can be a friction rod.

[0061] like Figures 1-5As shown, optionally, the driving member 6e faces the LED display assembly 30. When the LED display assembly 30 pushes towards the supporting assembly 20, it can push the driving member 6e to move, thereby driving the driving wheel 6d to rotate, so that the second positioning member 6b2 rotates to the same magnetic pole as the first positioning member 6b1. A second elastic member 6f is provided on the side of the driving member 6e away from the LED display assembly 30. The second elastic member 6f gives the driving member 6e a force to move towards the LED display assembly 30. The force of the driving member 6e moving towards the LED display assembly 30 can cause the driving wheel 6d to rotate, so that the second positioning member 6b2 rotates to the same magnetic pole as the first positioning member 6b1. 1. The magnetic poles are opposite; the LED display assembly 30 is provided with a clearance hole, and the first positioning member 6b1 is provided in the clearance hole. The first positioning member 6b1 can move axially relative to the clearance hole. When the LED display assembly 30 pushes the driving member 6e to move towards the bearing assembly 20, the first positioning member 6b1 can make way for the second positioning member 6b2 to prevent jamming; a third elastic member 6g is provided on the side of the first positioning member 6b1 away from the second positioning member 6b2. The third elastic member 6g gives the first positioning member 6b1 a force to move towards the second positioning member 6b2, so that the first positioning member 6b1 and the second positioning member 6b2 can keep in contact.

[0062] Optionally, the second rotating shaft 6c is provided with a delaying element (not shown in the figure), which can slow down the driving speed of the driving element 6e when the second elastic element 6f pushes the driving element 6e to move; so that the second positioning element 6b2 is delayed in attracting the first positioning element 6b1 after rotation, ensuring sufficient operation time.

[0063] Preferably, the delaying element can be a liquid retarder installed at the second rotating shaft 6c.

[0064] Preferably, the delaying element is a friction layer provided on the second rotating shaft 6c, which slows down the rotation of the second rotating shaft 6c driven by the driving element 6e through friction.

[0065] Optionally, the fixing mechanism 6b includes multiple sets and surrounds the limiting mechanism 6a.

[0066] Preferably, the fixing mechanism 6b consists of 4 groups.

[0067] Optionally, the connector a1 is located a distance away from the LED display component 30 from the limiting block 6a1, and the power supply port a2 is located inside the limiting hole 6a2, and the power supply port a2 always has a force that moves toward the LED display component 30.

[0068] like Figures 1-5As shown, when disassembly is required, the LED display assembly 30 is adsorbed by a negative pressure suction cup. Then, the LED display assembly 30 is pressed, and the LED display assembly 30 is driven by the driving component 6e to rotate the second positioning component 6b2. When the second positioning component 6b2 rotates to the same magnetic pole as the first positioning component 6b1, the repulsive force of the second positioning component 6b2 causes the first positioning component 6b1 to move away from the second positioning component 6b2. Then, the negative pressure suction cup is dragged to move the LED display assembly 30 away from the supporting component 20. At this time, the periphery of the LED display assembly 30 separates from the other LED display assemblies 30 on the periphery, and the second connector 80 of the LED display assembly 30 separates. During the movement of the LED display assembly 30, the locking block a22 always moves within the third locking slot 11c, so that the locking block a22... 22 will not be obstructed; however, at this time, the LED display component 30 will not separate under the action of the first slot 11a. If no further operation is taken, when the second elastic member 6f causes the second positioning member 6b2 to rotate to the opposite magnetic pole of the first positioning member 6b1, the LED display component 30 will be attracted and fixed by the strong magnet again. In this way, the problem of accidental removal can be prevented. If it is necessary to remove the LED display component 30, the LED display component 30 must first be pulled away from the support component 20 so that the LED display component 30 is not aligned with the adjacent LED display component 30. Then rotate the LED display component 30 so that the card block a22 moves along the first slot 11a to the second slot 11b. Finally, remove the LED display component 30.

[0069] When installation is required, simply reverse the removal process.

[0070] In summary, the present invention provides an LED display screen that, through the arrangement of a rotating component and a locking component, enables the carrier component to be inserted and removed in a horizontally positioned manner, ensuring the stability and convenience of the carrier component's installation and disassembly, and reducing the burden during operation.
