[0049] The display device in the embodiment of the present application rotates the LED display screen 200 on the supporting body 100, so that when the LED display screen 200 needs to be maintained, it is only necessary to rotate the LED display screen 200 to display the back side of the LED display screen 200 in front of the staff, and there is no need to perform post-maintenance on the LED display screen 200 from the back side of the supporting body 100 through the gap of the supporting body 100, which reduces the difficulty of post-maintenance of the LED display screen 200 and facilitates maintenance.

[0050] In one embodiment, see Figure 3 The display device includes two LED display screens 200, and the two LED display screens 200 are rotatably installed on the front and rear sides of the supporting body 100. Among them, since the LED display screen 200 is rotatably installed on the supporting body 100, it is not necessary to perform rear maintenance on the LED display screen 200 on the front side of the supporting body 100 from the rear side of the supporting body 100, so that an LED display screen 200 can be installed on both the front and rear sides of the supporting body 100, thereby realizing the double-sided display requirement, which has more application value. It can be understood that in other embodiments of the present application, according to actual application requirements, the above-mentioned display device may also include an LED display screen 200 and a poster, and the LED display screen 200 and the poster are rotatably installed on the front and rear sides of the supporting body 100, respectively, and this is not the only limitation here.

[0051] In one embodiment, see Figure 3The display device includes two covers 300, which are respectively covered on the front sides of the two LED display screens 200, and the two covers 300 are respectively rotatably connected to the front and rear sides of the support body 100. When the front LED display screen 200 needs to be maintained, it is only necessary to rotate the front cover 300 to open it, and then rotate the front LED display screen 200 to open it, which is simple to operate. When the rear LED display screen 200 needs to be maintained, it is only necessary to rotate the rear cover 300 to open it, and then rotate the rear LED display screen 200 to open it, which is simple to operate.

[0052] In one embodiment, see Fig.10 and Fig.11 The first side 210 is rotatably connected to the support body 100 via a hinge structure 400. Specifically, the hinge structure 400 includes a first hinge 410, a second hinge 420 and a rotating shaft 430. The first hinge 410 is mounted on the support body 100, the second hinge 420 is mounted on the first side 210 of the LED display screen 200, the rotating shaft 430 sequentially penetrates the first hinge 410 and the second hinge 420, the first hinge 410 is rotatably connected to the rotating shaft 430, the second hinge 420 is rotatably connected to the rotating shaft 430, and when the LED display screen 200 is pushed to rotate, the second hinge 420 rotates relative to the first hinge 410.

[0053] Specifically, the first hinge 410 and the second hinge 420 have the same structure. The first hinge 410 includes a connecting portion 411 and a rotating portion 412. The connecting portion 411 is locked on the support body 100 by screws. The connecting portion 411 and the rotating portion 412 are integrally connected. The rotating portion 412 is cylindrical and is sleeved on the rotating shaft 430.

[0054] See also Fig.11 A limiting head is formed at one end of the rotating shaft 430, and the rotating shaft 430 is sequentially inserted into the first hinge 410 and the second hinge 420, and the limiting head axially abuts against the side of the second hinge 420 away from the first hinge 410, and the other end of the rotating shaft 430 is fixedly sleeved on the locking member 440, and the locking member 440 axially abuts against the side of the first hinge 410 away from the second hinge 420, so that the axial position of the rotating shaft 430 can be limited by the limiting head and the locking member 440.

[0055] In one embodiment, see Figures 4 to 6A lock structure 500 is connected between the second side 220 and the supporting body 100. The lock structure 500 includes an opening member 540. The lock structure 500 can be unlocked by turning the opening member 540. That is, when the LED display screen 200 needs to be maintained, the lock structure 500 can be unlocked by turning the opening member 540 manually or with a tool, thereby easily pushing and rotating the LED display screen 200. The operation is simple and labor-saving.

[0056] In one embodiment, see Figure 5 and Figure 6 The lock structure 500 further includes a lock tongue 510, a lock buckle 520 and a locking member 530. The lock tongue 510 is mounted on the second side 220 of the LED display screen 200; the lock buckle 520 is rotatably mounted on the support body 100 and has an unlocking position and a locking position; the locking member 530 is rotatably mounted on the support body 100 and is connected to the opening member 540; the lock tongue 510 can be buckled into the lock buckle 520 in the unlocking position under the action of an external force and drive the lock buckle 520 to rotate to the locking position; the locking member 530 is used to keep the lock buckle 520 in the locking position; the locking member 530 can be driven to rotate by the opening member 540 to release the lock buckle 520.

[0057] Before the second side 220 of the LED display screen 200 is locked with the supporting body 100, the lock buckle 520 is in the unlocked position. The LED display screen 200 is driven to rotate by external force, driving the lock tongue 510 to move toward the lock buckle 520 and lock in the lock buckle 520. The LED display screen 200 is rotated continuously, and the lock tongue 510 drives the lock buckle 520 to rotate from the unlocked position to the locked position, and the lock buckle 520 in the locked position is locked by the locking member 530, so that the second side 220 of the LED display screen 200 remains locked on the supporting body 100. When the LED display screen 200 needs to be rotated to open, the opening member 540 is pushed by external force, and the opening member 540 drives the locking member 530 to rotate to release the lock buckle 520, so that the lock tongue 510 and the lock buckle 520 can be driven to rotate from the locked position to the unlocked position by rotating the LED display screen 200, and the lock tongue 510 is separated from the lock buckle 520, so that the LED display screen 200 can be rotated to open.

[0058] In one embodiment, see Figure 5The lock buckle 520 is formed with an opening slot 521, and when the lock tongue 510 rotates to a position corresponding to the opening slot 521, it can be inserted into the opening slot 521. The lock structure 500 also includes a lock frame 550, which is fixed to the support body 100. The lock buckle 520 is rotatably arranged on the lock frame 550 through a first mounting shaft 560. A first torsion spring 570 is mounted on the first mounting shaft 560, and the first torsion spring 570 is connected to the lock buckle 520. The first torsion spring 570 is used to keep the lock buckle 520 in the unlocked position, so that the lock tongue 510 can be accurately inserted into the opening slot 521 of the lock buckle 520.

[0059] In one embodiment, see Figure 6 The locking member 530 is rotatably mounted on the lock frame 550 via the second mounting shaft 580, and a second torsion spring 590 is mounted on the second mounting shaft 580. The locking member 530 has a first position and a second position. When the locking member 530 is in the first position, the lock buckle 520 is locked in the locking position, and the second torsion spring 590 is used to keep the locking member 530 in the first position; the opening member 540 is rotatably mounted on the lock frame 550, and the opening member 540 is in contact with the locking member 530. The opening member 540 is used to rotate to push the locking member 530 to rotate from the first position to the second position to release the lock buckle 520. Specifically, the locking member 530 and the lock buckle 520 can be clamped and limited by clamping.

[0060] The lock structure 500 is a common door lock structure, which will not be described in detail herein. It can be understood that in other embodiments of the present application, the lock structure 500 may also be other types of automatic locks, which are not limited to the only ones herein.

[0061] In one embodiment, see Figures 4 to 6A aligning assembly 600 is provided between the supporting body 100 and the second side 220 , and the aligning assembly 600 is used to lift the second side 220 upward when the LED display screen 200 is rotated and covered so that the second side 220 is aligned with the first side 210 up and down. In actual application, the first side 210 and the second side 220 are two opposite sides of the LED display screen 200 in the horizontal direction. When the LED display screen 200 is rotated to open, the first side 210 of the LED display screen 200 is hinged to the supporting body 100, and the second side 220 of the LED display screen 200 is not supported. Under the action of gravity, the second side 220 of the LED display screen 200 will fall relative to the first side 210, so that the LED display screen 200 is tilted. As a result, when the LED display screen 200 is rotated to cover, the lock tongue 510 and the lock buckle 520 are not accurately aligned, and the lock tongue 510 cannot be locked into the lock buckle 520. The setting of the alignment component 600 in this embodiment can lift the second side 220 of the LED display screen 200 downward through the alignment component 600, so that the second side 220 is aligned with the first side 210 up and down, so that the LED display screen 200 is not tilted, and the lock tongue 510 can be accurately buckled into the lock buckle 520, thereby realizing the rapid locking of the LED display screen 200.

[0062] In one embodiment, see Figure 5 and Figure 6 The alignment component 600 includes an alignment member 610 and a matching member 620. The alignment member 610 is mounted on the supporting body 100, and the matching member 620 is mounted on the second side 220 of the LED display screen 200. The alignment member 610 includes a guide portion 611 and a support portion 612 connected to each other. The guide portion 611 is arranged obliquely relative to the horizontal direction. The guide portion 611 is used to guide the matching member 620 from bottom to top to the support portion 612. The support portion 612 is arranged horizontally and is used to support the matching member 620 introduced by the guide portion 611. When the LED display screen 200 is rotated and covered, the matching piece 620 on the LED display screen 200 first passes through the guide part 611. If the second side 220 of the LED display screen 200 falls, the guide part 611 will guide the matching piece 620 from bottom to bottom so that the second side 220 of the LED display screen 200 is lifted up. When the guide part 611 lifts the second side 220 of the LED display screen 200 to be flush with the first side 210, the second side 220 of the LED display screen 200 is supported by the support part 612 to ensure that the LED display screen 200 remains in a flush state, thereby ensuring that the lock tongue 510 and the lock buckle 520 are accurately buckled.

[0063] In one embodiment, during the rotation and closing process of the LED display screen 200, the guide portion 611 is first guided and matched with the matching piece 620. When the matching piece 620 rotates to the position corresponding to the support portion 612, the lock tongue 510 begins to align and lock with the lock buckle 520. That is, it is necessary to ensure that the matching piece 620 enters the support portion 612 and the LED display screen 200 is flush from top to bottom before the lock tongue 510 begins to mate with the lock buckle 520.

[0064] In one embodiment, see Figure 5 and Figure 6 The straightening member 610 includes a mounting portion 613, a supporting portion 612 and a guiding portion 611, wherein the mounting portion 613, the supporting portion 612 and the guiding portion 611 are all plate-like structures and are connected in sequence, the mounting portion 613 is fitted and locked on the supporting body 100, the supporting portion 612 is a horizontal plate member perpendicular to the mounting portion 613, the guiding portion 611 is an inclined plate connected to the supporting portion 612, and the guiding portion 611 is an inclined plate extending from bottom to top to the supporting portion 612. When the LED display screen 200 is rotated, the matching member 620 moves upward from the bottom end of the guiding portion 611 and moves to the supporting portion 612.

[0065] In one embodiment, see Figure 5 and Figure 6 The matching piece 620 is a universal roller. When the LED display screen 200 is rotated and covered, the universal roller rolls from bottom to top on the guide part 611 and rolls horizontally on the support part 612. The rolling setting can reduce the friction between the matching piece 620 and the straightening piece 610, which is conducive to guiding the matching piece 620 to slide on the guide part 611 and the support part 612.

[0066] In one embodiment, see Figure 6 The alignment component 600 further includes a mounting member 630 , which is fixed on the LED display screen 200 , and the matching member 620 is rotatably mounted on the mounting member 630 .

[0067] In one embodiment, see Figure 7 and Figure 8 A limit assembly 700 is connected between the LED display screen 200 and the supporting body 100 to limit the rotation angle range of the LED display screen 200. In practical applications, due to the heavy weight and large volume of the LED display screen 200, if the LED display screen 200 is rotated at an excessive angle, the LED display screen 200 may collide with the cover 300 or other structures, or the entire display device may deviate from its center of gravity and fall over. The setting of the limit assembly 700 can limit the rotation angle of the LED display screen 200 to prevent the LED display screen 200 from rotating at an excessive angle.

[0068] In one embodiment, see Figure 8 The limiting assembly 700 includes a limiting member 710 and a limiting rod 720. The limiting member 710 is mounted on the supporting body 100, and an arc groove 711 is formed on the limiting member 710. The limiting rod 720 is mounted on the LED display screen 200, and the limiting rod 720 is slidably limited in the arc groove 711. Specifically, the center of the arc groove 711 is located on the rotation center axis of the LED display screen 200. When the LED display screen 200 rotates relative to the supporting body 100, the limiting rod 720 slides in an arc in the arc groove 711. When the limiting rod 720 slides to the opposite ends of the arc groove 711, the limiting rod 720 is limited, thereby limiting the rotation angle of the LED display screen 200.

[0069] In one embodiment, see Fig. 9 , Fig.10 and Fig.12 , two first profiles 230 are respectively installed on opposite sides of the back of the LED display screen 200, and the limiting rod 720, the mounting member 630 and the locking tongue 510 are all installed on the first profile 230. Among them, through the arrangement of the first profile 230, it is only necessary to install the limiting rod 720, the matching member 620 and the locking tongue 510 on the first profile 230, and it is not necessary to install the matching member 620 and the locking tongue 510 on the back of the LED display screen 200, which simplifies the design of the LED display screen 200. In addition, before the first profile 230 is assembled on the back of the LED display screen 200, the mounting member 630 can be locked on the supporting body 100 by screws, so that the first profile 230 can also be installed on the supporting body 100 and carried together with the supporting body 100. After the first profile 230 is fixed on the LED display screen 200, the screws can be removed so that the mounting member 630 and the matching member 620 can move relative to the straightening member 610.

[0070] In one embodiment, see Figure 4 The supporting body 100 includes an inner frame 110, an outer frame 120 and a plurality of connecting members 130.
