[0002] With the wide application of outdoor LED displays in the fields of advertising, activities, on-site displays, etc., users have put forward higher requirements for their portability, flexibility, and operation convenience.

[0003] Traditional outdoor LED displays are generally fixed by fixed brackets. Although the stability during installation can be improved, when it needs to be moved later, the fixed brackets must be removed for transportation and then reinstalled, which greatly reduces its portability. Moreover, the angle needs to be adjusted during the installation of the outdoor LED display, and it is inconvenient to adjust the angle of the fixed brackets. Therefore, there is an urgent need to design an outdoor LED display that is convenient to carry, has high stability, and is convenient for angle adjustment. Summary of the Invention

[0004] In order to design an outdoor LED display that is convenient to carry, has high stability, and is convenient for angle adjustment, the present application provides an outdoor LED display with an adjustment function.

[0005] An outdoor LED display with an adjustment function provided by the present application adopts the following technical solutions: An outdoor LED display with an adjustment function includes a frame, an LED display body arranged on the frame, and a support adjustment mechanism. The support adjustment mechanism includes: A frame body, which is arranged on the frame and is provided with a plurality of installation grooves at intervals; A main support member, one end of which is rotatably installed at the bottom of the installation groove through a first rotating shaft; A sub-support member, the top of which is rotatably installed on the receiving groove through a control mechanism and the bottom of which is rotatably connected to the end of the main support member away from the first rotating shaft through a second rotating shaft. The axes of the first rotating shaft and the second rotating shaft are parallel; the control mechanism is used to control the position of the top of the sub-support member, so that both the main support member and the sub-support member can be rotated into the installation groove for storage, or so that the main support member and the sub-support member are rotated outside the installation groove and form a triangular structure for support.

[0006] By adopting the above technical solutions, when it is necessary to support and place the display screen, the control mechanism adjusts the sub-support member to be close to the main support member, thereby pushing the main support member and the sub-support member to rotate outside the installation groove to form a triangular structure for support, and at the same time making the length direction of the main support member form a certain angle with the height of the display screen, so as to make the support effect on the display screen better.

[0007] When the angle needs to be adjusted, the control mechanism adjusts the position of the top of the secondary support member in the installation groove, while the primary support member supports on the ground without rotating, thereby driving the frame body and the display screen to rotate, so as to adjust the placement angle of the display screen; at the same time, when it needs to be carried and transported, the control mechanism adjusts the position of the top of the secondary support member, so that the secondary support member and the primary support member rotate towards the installation groove, and the secondary support member and the primary support member are both rotated into the installation groove for storage, thereby obtaining a display screen that is convenient to carry, has high stability and is convenient to adjust the angle.

[0008] At the same time, the primary support member and the secondary support member rotate and form a triangular structure, which improves the support and positioning effect on the display screen, and the force exerted by the secondary support member on the control mechanism is a force in an inclined direction, thereby realizing the decomposition of this force into forces in multiple directions, reducing the force on the control mechanism, and further improving the support effect on the display screen, making the display screen more stable.

[0009] Optionally, the control mechanism includes: A plurality of control rods are arranged at intervals on the installation groove along a direction perpendicular to the axis of the first rotating shaft, and a clamping groove for clamping and cooperating with the control rods is formed at the top of the secondary support member; a receiving groove is formed on the side wall of the primary support member close to the installation groove; A positioning assembly for connecting the secondary support member with a certain control rod and for positioning the top of the secondary support member; A support assembly is rotatably arranged on the first rotating shaft and can be rotated into the receiving groove for storage. When the primary support member and the secondary support member support the LED display screen body, the support assembly rotates out of the receiving groove and is connected with the secondary support member and is used for supporting and positioning the secondary support member.

[0010] By adopting the above technical solution, the clamping groove on the secondary support member is clamped and cooperated with a certain control rod, and the positioning assembly is positioned, so that the position of the top of the secondary support member can be adjusted, and the positions and angles of the primary support member and the secondary support member can be adjusted. After the adjustment is completed, the support assembly rotates to the outside of the receiving groove, so that the top of the support assembly is connected with the lower surface of the secondary support member for support, thereby further realizing force decomposition. Moreover, the force exerted by the secondary support member on the control rod is a force in an inclined direction, and this force is decomposed into two forces in the vertical direction and the horizontal direction, thereby greatly reducing the force on the control rod in the vertical direction, making the display screen more convenient to carry, more stable and more convenient to adjust the angle.

[0011] Optionally, the positioning assembly includes: A positioning rod is rotatably installed on the secondary support member; A positioning piece is arranged on the positioning rod and presses against the control rod for positioning.

[0012] By adopting the above technical solution, the positioning rod rotates to drive the positioning piece to approach and press against the control rod, thereby realizing the fixed connection between the secondary support member and the primary support member. Or, the positioning piece moves away from the control rod, thus realizing the removal of the secondary support member from the primary support member.

[0013] Optionally, the support assembly includes: A first bearing plate, rotatably mounted on a first rotating shaft; A second bearing plate, rotatably mounted on one end of the first bearing plate away from the first rotating shaft through a rotating shaft, and a support groove is formed at one end away from the second rotating shaft. The axes of the rotating shaft and the first rotating shaft are parallel to each other; Support blocks, arranged on the secondary support member and provided with a plurality of arc-shaped convex ribs at intervals along the length direction of the secondary support member; An arc-shaped rod, arranged on the receiving groove; A locking member, used to lock and position the positions of the first bearing plate and the second bearing plate and make the length directions of the first bearing plate and the second bearing plate parallel, so that the support groove is engaged with a certain arc-shaped convex rib to support and position the secondary support member. Or, the support groove is engaged with the arc-shaped rod so that the first bearing plate and the second bearing plate are located in the receiving groove for storage.

[0014] By adopting the above technical solution, after the angle adjustment between the secondary support member and the primary support member is completed, the locking member is unlocked, and the locking member is pulled to drive the first bearing plate and the second bearing plate to rotate relative to each other, so that the first bearing plate and the second bearing plate are taken out from the receiving groove. The second bearing plate is rotated close to the arc-shaped convex rib, and at the same time, the first bearing plate and the second bearing plate are rotated so that their length directions are parallel to each other, so that the support groove is engaged with the arc-shaped convex rib at a suitable position. Finally, the locking member locks and positions the positions of the first bearing plate and the second bearing plate, thereby realizing the support and positioning of the secondary support member and the primary support member.

[0015] When it is necessary to carry and transport, the first bearing plate and the second bearing plate are placed into the receiving groove by the same method, and the locking member is locked so that the support groove is engaged with the arc-shaped rod for positioning. Therefore, when the primary support member is rotated into the installation groove, the support assembly will not interfere with the placement of the primary support member, making the carrying of the display screen more convenient and more stable.

[0016] Optionally, the locking member is a locking screw, and a positioning hole is formed on the second rotating shaft. The locking screw is threadedly connected to the second bearing plate or the first bearing plate and extends into the positioning hole and is used to position the positions of the first bearing plate and the second bearing plate.

[0018] Optionally, the control mechanism includes: The control block is slidably arranged on the installation groove along a direction perpendicular to the axis of the rotating shaft and is rotatably connected to the top of the auxiliary support through a connecting component; The driving part is used to drive the control block to move; The limiting component is used to limit the position of the control block.

[0019] By adopting the above technical solution, the driving part drives the control block to move, and the movement of the control block drives the auxiliary support and the main support to move and rotate simultaneously, so as to adjust the positions and angles of the auxiliary support and the main support. After the adjustment is completed, the limiting component limits the position of the control block, so that the adjustment can be automatically realized, and even controlled by a remote control mechanism, which improves the convenience during control. Moreover, the limiting component limits the position, which further makes the display screen more convenient to carry, more stable and more convenient to adjust the angle.

[0020] The force exerted by the auxiliary support on the control block is an inclined force, which greatly reduces the force on the driving part, thus improving the safety of the driving part, making the display screen more stable, and at the same time, the control block or the auxiliary support can be replaced through the connecting component.

[0021] Optionally, a rotating hole is formed in the auxiliary support, and the connecting component includes: The mounting plate is detachably arranged on the control block; The mounting shaft is arranged on the mounting plate and extends into the rotating hole to realize the rotational connection between the auxiliary support and the control block.

[0022] By adopting the above technical solution, after the mounting plate is disassembled, the mounting plate is driven so that the mounting shaft disengages from the rotating hole, thereby replacing the control block and the driving part. During installation, the rotating hole is aligned with the mounting shaft, the mounting plate is pushed so that the mounting shaft extends onto the rotating hole, and the mounting plate is fixed, thereby realizing the rotational connection between the control block and the auxiliary support.

[0023] Optionally, the limiting component includes: The toothed bar is slidably arranged on the frame along a direction close to or away from the control block, and the sliding direction is perpendicular to the sliding direction of the control block. A toothed groove is formed in the control block; The elastic member is connected to the frame and the toothed bar and is used to push the toothed bar close to the control block and make the toothed bar inserted into the toothed groove for positioning.

[0024] By adopting the above technical solution, when positioning is required, the toothed bar is inserted into the toothed groove for positioning under the action of the elastic member. When the control block moves, it drives the control block to move, and the contact between the toothed bar and the toothed groove is in an inclined state, so that it is convenient to push the toothed bar away from the control block under the driving action of the control block, thereby realizing unlocking, which improves the convenience during unlocking and locking.

[0025] Optionally, rolling components are provided on both sides of a plurality of installation grooves on the frame body. A vertical adjustment hole is formed in the frame body along the length direction of the installation groove. The rolling component includes: A fixing screw that passes through the adjustment hole and is threadedly connected to the frame and presses against the frame body for positioning; A rotating seat that is rotatably mounted on the frame body through a rotating member and the bottom extends below the frame. The rotating member presses against the rotating seat to position the rotating seat; A roller that is rotatably mounted on the bottom of the rotating seat and rolls on the ground for support.

[0026] By adopting the above technical solution, multiple rollers roll on the ground for support, so as to cooperate with the main support member to support the display screen. At the same time, the display screen can also be moved through the rollers. After unscrewing the fixing screw to disengage from the frame body, the rotating seat rotates to drive the roller to rotate, so as to realize the adjustment of the position of the frame body. After the adjustment is completed, screw the fixing screw to press against the frame body for positioning.

[0027] Optionally, a plurality of fixing blocks are arranged at intervals on the fixing screw. The head of the fixing screw and the fixing blocks both press against the frame body for positioning.

[0028] By adopting the above technical solution, the fixing blocks increase the contact area with the frame body, improve the positioning effect on the frame body, and at the same time, the plurality of fixing blocks also facilitate the exertion of force when screwing the fixing screw.

[0029] In summary, the present application includes at least one of the following beneficial technical effects: 1. When it is necessary to support and place the display screen, the control mechanism pushes the main support member and the auxiliary support member to form a triangular structure for support; when it is necessary to adjust the angle, the control mechanism adjusts the position of the auxiliary support member to adjust the placement angle of the display screen; at the same time, when it is necessary to carry and transport, the control mechanism adjusts the position of the top of the auxiliary support member so that both the auxiliary support member and the main support member are rotated into the installation groove for storage, thereby obtaining a display screen that is convenient to carry, has high stability, and is convenient to adjust the angle.

[0030] 2. By rotating the main support member and the auxiliary support member to form a triangular structure, the support and positioning effect on the display screen is improved, and the force exerted by the auxiliary support member on the control mechanism is an inclined force, so as to realize the decomposition of this force into forces in multiple directions, reduce the force exerted on the control mechanism, and further improve the support effect on the display screen, making the display screen more stable.

When the control block 61 moves, the inclined toothed groove makes it easier to push the toothed strip 71 away from the toothed groove to unlock the control block 61.

[0056] The working principle of the embodiment of the present application is as follows: The driving member 62 drives the control block 61 to move. The movement of the control block 61 drives the secondary support member 23 and the main support member 22 to move and rotate, so as to adjust the positions and angles of the secondary support member 23 and the main support member 22, thereby realizing the support placement, angle adjustment and carrying and transportation of the LED display screen body. Therefore, the convenience of using the LED display screen body can be improved.

[0057] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited thereby. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
