Description

Technical Field

[0001] This utility model relates to the field of outdoor LED display technology, specifically a bottom shell structure for an outdoor LED display. Background Technology

[0002] Outdoor LED displays are a type of display device, consisting of multiple neatly arranged light-emitting diodes. They are modular and easy to maintain, and are widely used in outdoor settings for product promotion.

[0003] In order to solve the problem of inconvenient installation of upper and lower displays, existing technologies include components such as springs and conical blocks inside the display screen. The springs push the conical blocks to fix the inserts, which can connect and fix the upper and lower displays. However, this type of fixing structure cannot stably fix the position of a display screen. When it is necessary to maintain or replace the bottom display screen in a linearly arranged display screen, the upper display screen cannot be fixed when the screen is removed, and it is easy to slip, which reduces the safety and stability during maintenance.

[0004] To address these issues, we provide a base structure for outdoor LED displays. Utility Model Content

[0005] 1) Technical problems to be solved

[0006] This utility model proposes a bottom shell structure for an outdoor LED display screen, which solves the problem of unstable fixation of the display screen through the cooperation between fixing plate one, fixing plate two and fixing shaft.

[0007] (ii) Technical Solution

[0008] To achieve the above objectives, this utility model provides the following technical solution: a bottom shell structure for an outdoor LED display screen, including a frame, on the outside of which the display screen body is mounted, and multiple sets of fixing grooves are opened inside the frame, with a limit plate fixedly installed on the inner wall of the fixing groove.

[0009] A fixing frame is fixedly installed on the inner wall of the frame. A fixing shaft is fixedly installed inside the fixing frame. A rotating mechanism is installed on the outer surface of the fixing shaft. Fixing plate one and fixing plate two are respectively installed on the outside of the rotating mechanism. Clamping plate one and clamping plate two are respectively fixedly installed on the outer surfaces of fixing plate one and fixing plate two.

[0010] A connecting frame is fixedly installed on the outer surface of the second fixing plate, and an insert plate is rotatably connected to the outer surface of the connecting frame.

[0011] Furthermore, the fixing grooves are symmetrically arranged inside the frame, and the limiting plate is installed near the outer side of the fixing grooves.

[0012] Furthermore, the rotating mechanism includes a first fixed ring and a second fixed ring, the outer surface of the fixed shaft is rotatably connected to the interior of both the first and second fixed rings, and the first fixed plate and the second fixed plate are respectively fixedly installed on the outer surfaces of the first and second fixed rings.

[0013] Furthermore, the fixing frame has an L-shaped structure and is made of aluminum alloy, and the fixing frame is arranged diagonally inside the frame.

[0014] Furthermore, the outer surfaces of the first fixing plate and the second fixing plate are slidably connected to the inner wall of the fixing groove, and the first clamping plate and the second clamping plate are slidably connected to the inner wall of the frame.

[0015] Furthermore, the fixed plate has an insertion hole arranged in a straight line inside, and the outer surface of the insertion plate is slidably connected to the inside of the insertion hole.

[0016] Furthermore, a spring is fixedly installed on the outer surface of the second fixing plate, and the other end of the spring is fixedly installed on the outer surface of the insert plate and applies tension to the insert plate.

[0017] (iii) Beneficial effects:

[0018] Compared with existing technologies, the bottom shell structure of this outdoor LED display screen has the following advantages:

[0019] 1. The bottom shell structure of this outdoor LED display screen, through the cooperation between fixing plate one, fixing plate two and fixing shaft, allows fixing plate one and fixing plate two to rotate outside the fixing shaft. Fixing plate one and fixing plate two can drive clamping plate one and clamping plate two to contact the inner wall of the frame. At this time, adjacent frames can be connected and fixed. In this way, the display screen is fixed at the top and bottom and on both sides. Even when the bottom display screen is pulled out, the upper frame is not easy to fall off, which improves the safety during maintenance, realizes the function of stable fixing of each display screen, and reduces the risk of slippage when the display screen is suspended in the air for maintenance.

[0020] Second, the bottom shell structure of this outdoor LED display screen is designed with components such as insert plates and springs. When the first and second fixing plates are fixed to the frame, they are in a vertical state. At this time, moving the insert plate will allow it to enter the interior of the socket. The spring will exert a continuous pulling force on the insert plate, bringing it closer to the first fixing plate, which improves the stability of the insert plate when it is fixed. At this time, the first fixing plate, the second fixing plate, and the insert plate form a triangular support structure, which is more stable when fixed. Attached Figure Description

[0028] 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.

[0029] like Figures 1-5 As shown, this utility model provides a technical solution: a bottom shell structure for an outdoor LED display screen, including a frame 1, a display screen body 2 installed on the outside of the frame 1, a U-shaped support frame installed on the bottom of the frame 1 to facilitate the installation and fixing of the frame 1 on the external bracket, multiple sets of fixing grooves 3 are opened inside the frame 1, the fixing grooves 3 are symmetrically arranged inside the frame 1, a limiting plate 4 is fixedly installed on the inner wall of the fixing groove 3, the limiting plate 4 is installed near the outer side of the fixing groove 3, the fixing groove 3 passes through the back of the frame 1, and the limiting plate 4 is installed at the edge position, thereby forming an installation groove with an opening between the fixing groove 3, the limiting plate 4 and the frame 1.

[0030] A fixing frame 5 is fixedly installed on the inner wall of the frame 1. A fixing shaft 6 is fixedly installed inside the fixing frame 5. The fixing frame 5 has an L-shaped structure and is made of aluminum alloy. The fixing frame 5 is set diagonally inside the frame 1. The aluminum alloy fixing frame 5 can stably support the fixing shaft 6. One end of the fixing shaft 6 is directly fixed to the outside of the fixing frame 5.

[0031] A rotating mechanism 7 is installed on the outer surface of the fixed shaft 6. A first fixed plate 8 and a second fixed plate 9 are respectively installed on the outside of the rotating mechanism 7. The rotating mechanism 7 can control the rotation of the first fixed plate 8 and the second fixed plate 9. The outer surfaces of the first fixed plate 8 and the second fixed plate 9 are slidably connected to the inner wall of the fixed groove 3. When the first fixed plate 8 and the second fixed plate 9 rotate and open relative to each other, they are in a vertical state. At this time, one side of the first fixed plate 8 and the second fixed plate 9 will contact one side of the limiting plate 4. The limiting plate 4 is used to block the first fixed plate 8 and the second fixed plate 9 from moving back and forth.

[0032] The rotating mechanism 7 includes a first fixed ring 701 and a second fixed ring 702. The outer surface of the fixed shaft 6 is rotatably connected to the interior of the first fixed ring 701 and the second fixed ring 702. The first fixed plate 8 and the second fixed plate 9 are fixedly installed on the outer surfaces of the first fixed ring 701 and the second fixed ring 702, respectively. The first fixed plate 8 and the second fixed plate 9 are connected to the fixed shaft 6 through the first fixed ring 701 and the second fixed ring 702. Under the action of the first fixed ring 701 and the second fixed ring 702, they can be rotated to open and close.

[0033] The outer surfaces of fixing plate 8 and fixing plate 9 are respectively fixedly installed with clamping plate 10 and clamping plate 21. Clamping plate 10 and clamping plate 21 are slidably connected to the inner wall of frame 1. When fixing plate 8 and fixing plate 29 are perpendicular, clamping plate 10 and clamping plate 21 will contact the inner wall of frame 1. Clamping plate 10 and clamping plate 21 can limit the two sides of frame 1. Since the limiting plate 4 limits one side of fixing plate 8 and fixing plate 29, after being limited by clamping plate 10 and clamping plate 21, the adjacent frames 1 can be connected to each other. When disassembling, it is only necessary to rotate fixing plate 8 and fixing plate 29 to disengage from the limiting plate 4, and then the frame 1 can be taken out from the front and back.

[0034] A connecting bracket 12 is fixedly installed on the outer surface of the second fixing plate 9. A plug plate 13 is rotatably connected to the outer surface of the connecting bracket 12. A plug hole 14 is opened inside the first fixing plate 8 and is arranged in a straight line. The outer surface of the plug plate 13 is slidably connected to the inside of the plug hole 14. When the first fixing plate 8 and the second fixing plate 9 are opened vertically, the plug plate 13 is rotated into the inside of the plug hole 14. At this time, the first fixing plate 8, the second fixing plate 9 and the plug plate 13 form a triangular support structure, which improves the stability of the first fixing plate 8 and the second fixing plate 9 when they are perpendicular.

[0035] A spring 15 is fixedly installed on the outer surface of the fixing plate 2 9. The other end of the spring 15 is fixedly installed on the outer surface of the insert plate 13 and applies a pulling force to the insert plate 13. The spring 15 will generate a continuous pulling force on the insert plate 13 that approaches the fixing plate 1 8, which improves the stability of the insert plate 13 when it is fixed, making it more stable when fixed.

[0036] Working principle: During installation, first ensure that the included angle between fixing plate 8 and fixing plate 9 is less than 90°. Then connect the upper and lower frames 1 and insert fixing plate 8 and fixing plate 9 into the adjacent fixing slots 3 respectively. Then rotate fixing plate 8 and fixing plate 9 to fit tightly against the fixing slots 3 and contact one side of the limiting plate 4. At this time, clamping plate 10 and clamping plate 21 will contact the inner wall of frame 1. Adjacent frames 1 are fixed by clamping plate 10 and clamping plate 21. Then insert plate 13 into the insertion hole 14. At this time, spring 15 can generate continuous tension on insert plate 13. Fixing plate 8 and fixing plate 29 are in a stable vertical state. One side of fixing plate 8 and fixing plate 29 is limited by the limiting plate 4. The overall frame 1 is installed. When a set of frames 1 is disassembled, adjacent frames 1 can be fixed and supported by each other.
