Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically an LED display screen for multi-angle adjustment. Background Technology

[0002] LED displays are electronic displays composed of LED dot matrices. They change the form of the displayed content, such as text, animation, pictures, and videos, by turning red and green LED beads on and off. They use a modular structure for component display control and are mainly divided into display modules, control systems, and power systems. LED screens can realize the conversion between different forms of various information presentation modes and can be used both indoors and outdoors. They have unparalleled advantages over other displays, such as high light intensity, low power consumption, and low voltage requirements.

[0003] LED displays are typically placed on a contact surface using brackets to achieve their intended use. When the contact surface is slightly tilted, the LED display placed on it will also be tilted, causing the displayed content to be skewed and increasing the difficulty for users to view it. Utility Model Content

[0004] To address the shortcomings of existing technologies, where LED displays placed on contact surfaces tend to tilt when the contact surfaces are slightly skewed, resulting in skewed content and increased viewing difficulty for users, this invention proposes a multi-angle adjustable LED display.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a multi-angle adjustable LED display screen, including a support base, a connecting rod provided on the top of the support base, a support rod provided on the top of the connecting rod, the inner wall of the support rod and the surface of the connecting rod being rotatably connected by a damping shaft, a mounting block provided at one end of the support rod, the LED display screen body being fixedly connected to the mounting block by bolts, and an adjustment mechanism provided at one end of the support rod; The adjustment mechanism includes a rotating shell, which is fixedly installed at one end of a support rod. A hiding box is rotatably connected to the inner cavity of the rotating shell. The inner cavity of the hiding box is used in conjunction with a mounting block. A first gear is fixedly installed on the surface of the hiding box. A second gear is rotatably connected to the inner wall of the rotating shell. The teeth of the first gear and the second gear mesh with each other.

[0006] Preferably, a limiting rod is slidably connected to the inner wall of the rotating shell, and the limiting rod is used in conjunction with the teeth of the first gear.

[0007] Preferably, both the hiding box and the mounting block have mating grooves on their tops, and the mating block is slidably connected to the inner cavity of the mating groove.

[0008] Preferably, springs are fixedly installed on the top of the hiding box and the top of the rotating shell, and the other ends of the two springs are fixedly connected to the surfaces of the docking block and the limiting rod, respectively.

[0009] Preferably, a limiting groove is formed on the inner wall of the rotating shell, and a limiting block is fixedly installed on the surface of the first gear, with the surface of the limiting block slidably connected to the inner cavity of the limiting groove.

[0010] Preferably, the inner wall of the support base is rotatably connected to a threaded sleeve, the inner wall of the threaded sleeve is movably connected to a lead screw, a lifting block is fixedly installed on the surface of the connecting rod, and the top of the lead screw is fixedly connected to the bottom of the lifting block.

[0011] Preferably, a guide block is fixedly installed on the top of the support base, and the surface of the guide block is slidably connected to the inner cavity of the connecting rod.

[0012] The advantages of this utility model are: 1. This utility model, by setting an adjustment mechanism, places the support base on the contact surface. If the contact surface is in an inclined state, by rotating the second gear, the first gear is driven to rotate, thereby enabling the hiding box to rotate inside the rotating shell. The hiding box and the rotating shell can remain connected during the rotation, thereby changing the placement angle of the LED display body and keeping the LED display body in a horizontal state, thus avoiding the tilt of the LED display body.

[0013] 2. This utility model uses a threaded sleeve, a lead screw, a lifting block, and a guide block in combination. By rotating the threaded sleeve 12, the connecting rod can be pushed upward through the threaded connection between the threaded sleeve and the lead screw, thereby changing the height of the LED display body and making the use of the LED display body more in line with the user's needs.

[0014] 3. This utility model, through the combined use of the limiting groove and the limiting block, can limit the rotation of the first gear, allowing the first gear to deflect within a suitable range and preventing excessive deflection of the first gear. Attached Figure Description

[0018] 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 scope of protection of the present utility model.

[0019] The following is in conjunction with the appendix Figure 1-8 This application will be described in further detail. This application discloses an LED display screen for multi-angle adjustment. (See also...) Figures 1 to 5 A multi-angle adjustable LED display screen includes a support base 1, a connecting rod 2 is provided on the top of the support base 1, a support rod 3 is provided on the top of the connecting rod 2, the inner wall of the support rod 3 is rotatably connected to the surface of the connecting rod 2 through a damping shaft, a mounting block 4 is provided at one end of the support rod 3, the LED display screen body 5 is fixedly connected to the mounting block 4 by bolts, and an adjustment mechanism 6 is provided at one end of the support rod 3. The adjustment mechanism 6 includes a rotating shell 601, which is fixedly installed at one end of the support rod 3. A hiding box 602 is rotatably connected to the inner cavity of the rotating shell 601. The inner cavity of the hiding box 602 is used in conjunction with the mounting block 4. A first gear 603 is fixedly installed on the surface of the hiding box 602. A second gear 604 is rotatably connected to the inner wall of the rotating shell 601. The teeth of the first gear 603 and the second gear 604 mesh with each other. By setting the adjustment mechanism 6, the support base 1 is placed on the contact surface. If the contact surface is in an inclined state, by rotating the second gear 604, the first gear 603 is driven to rotate, thereby enabling the hiding box 602 to rotate in the inner cavity of the rotating shell 601. The hiding box 602 and the rotating shell 601 can maintain connection during rotation, thereby changing the placement angle of the LED display body 5 and keeping the LED display body 5 in a horizontal state, thus avoiding the tilt of the LED display body 5.

[0020] Reference Figure 3 A limiting rod 7 is slidably connected to the inner wall of the rotating shell 601. The limiting rod 7 is used in conjunction with the teeth of the first gear 603. By setting the limiting rod 7, when the first gear 603 rotates, the limiting rod 7 is inserted into the inner cavity of the rotating shell 601, so that the reserved slot of the limiting rod 7 meshes with the teeth of the first gear 603, thereby limiting the angle after rotation. Reference Figure 3 and Figure 4 Both the hiding box 602 and the mounting block 4 have a docking groove 8 on their tops. The inner cavity of the docking groove 8 is slidably connected to the docking block 16. By setting the docking groove 8 and the docking block 16, when the mounting block 4 enters the inner cavity of the hiding box 602, it enters the inner cavity of the docking groove 8 through the docking block 16, thereby fixing the position of the mounting block 4. Reference Figure 4 Springs 9 are fixedly installed on the top of the hiding box 602 and the top of the rotating shell 601. The other ends of the two springs 9 are fixedly connected to the surfaces of the docking block 16 and the limiting rod 7, respectively. By setting the springs 9, the limiting rod 7 and the docking block 16 can be automatically reset under the reaction of the springs 9. Reference Figure 3 and Figure 5 A limiting groove 10 is provided on the inner wall of the rotating shell 601. A limiting block 11 is fixedly installed on the surface of the first gear 603. The surface of the limiting block 11 is slidably connected to the inner cavity of the limiting groove 10. Through the slidable connection between the limiting groove 10 and the limiting block 11, the rotation of the first gear 603 can be limited, so that the first gear 603 can deflect within a suitable range and avoid excessive deflection of the first gear 603. Reference Figure 6 and Figure 7The inner wall of the support base 1 is rotatably connected to a threaded sleeve 12, and the inner wall of the threaded sleeve 12 is movably connected to a lead screw 13. A lifting block 14 is fixedly installed on the surface of the connecting rod 2. The top of the lead screw 13 is fixedly connected to the bottom of the lifting block 14. By setting the threaded sleeve 12, when the height is not sufficient, by rotating the threaded sleeve 12, the lifting block 14 is moved upward through the threaded connection between the threaded sleeve 12 and the lead screw 13, which can push the connecting rod 2 to move upward, thereby changing the height of the LED display body 5. Reference Figure 6 A guide block 15 is fixedly installed on the top of the support base 1. The surface of the guide block 15 is slidably connected to the inner cavity of the connecting rod 2. By setting the guide block 15, the movement of the connecting rod 2 can be guided, and the connecting rod 2 can move up and down while remaining vertical.

[0021] Working Principle: During the installation of the LED display body 5, the mounting block 4 is aligned with the LED display body 5, and bolts are used to fix the mounting block 4 to the LED display body 5. After fixing, the mounting block 4 is inserted into the inner cavity of the concealment box 602. Through the bolt holes reserved in the inner cavity of the concealment box 602, the concealment box 602 can completely enclose the mounting block 4. The base is placed on the contact surface. If the contact surface is in an inclined state, the second gear 604 is rotated, which drives the first gear 603 to rotate, thereby allowing the concealment box 602 to rotate within the inner cavity of the rotating shell 601. The concealment box 602 and the rotating shell 601 remain connected during rotation, thus enabling the LED display to rotate. The placement angle of the LED display body 5 is changed to make it horizontal, avoiding tilting. When the angle does not meet the usage requirements, the LED display body 5 is pushed backward. Through the rotation between the support rod 3 and the connecting rod 2, the angle of the LED display body 5 can be changed. The damping shaft limits the angle after rotation, thereby changing the elevation angle of the LED display body 5. When the height is not sufficient, the threaded sleeve 12 is rotated. Through the threaded connection between the threaded sleeve 12 and the lead screw 13, the connecting rod 2 can be pushed upward, thereby changing the height of the LED display body 5 and making the use of the LED display body 5 more in line with the user's needs.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
