Description

Technical Field

[0001] This utility model belongs to the field of LED displays, and more specifically, it relates to a multifunctional LED display. Background Technology

[0002] As a widely used flat panel display device, LED displays play a crucial role in information display in large public spaces. However, most mainstream multi-functional LED screens currently use a wall-mounted installation method, which has significant limitations: because the screen angle is completely fixed, it cannot be adjusted according to the actual viewing position of the audience. Viewers need to sit in a suitable position, otherwise problems such as screen reflection and color distortion may occur, seriously affecting the viewing experience. In terms of screen maintenance, most users still rely on ordinary cleaning cloths for surface cleaning. This simple cleaning method has certain hidden dangers—the surface of LED screens is usually covered with optical coatings and precision circuit structures. The friction of ordinary cloth fibers may cause coating wear or electrostatic damage. Long-term use can easily lead to display spots, brightness decay, and other malfunctions, thus shortening the lifespan of the equipment. Utility Model Content

[0003] To address the aforementioned technical problems, this utility model provides a multi-functional LED display screen, which solves the issues of inconvenient angle adjustment and viewing comfort when using existing multi-functional LED display screens, as well as the risk of screen wear when cleaning with a cleaning cloth.

[0004] This utility model provides a multifunctional LED display screen, achieved through the following specific technical means:

[0005] A multifunctional LED display screen includes a base and a fixed frame. The base has casters at its bottom and a column supporting it. A first rotating support rod is mounted on the top of the column, and a first rotating bracket is rotatably connected to the first rotating support rod. A mounting plate is fixedly connected to the first rotating bracket, and the mounting plate is bolted to the fixed frame. The display screen body is installed and fixed within the fixed frame. A second rotating bracket is located at the rear of the fixed frame, and a second rotating support rod is rotatably connected to the second rotating bracket. A rotating sleeve is mounted on the second rotating support rod, and a component is inserted through the rotating sleeve. An adjusting rod is connected to the fixed frame, forming a rotatable connection. The adjusting rod has two sets of positioning plates, and a rotating sleeve is positioned between the two sets of positioning plates. A threaded rod is fixedly connected to one end of the adjusting rod, and the central axis of the threaded rod coincides with the central axis of the adjusting rod. A rotating handle is provided at one end of the adjusting rod. Guide plates are provided on the upper and lower sides of the fixed frame. A sliding sleeve is slidably connected to the guide plate. A cable tie plate is provided on the sliding sleeve, and an air pipe is inserted through the cable tie plate. One end of the air pipe faces the display screen body, and the other end is connected to an air pump. The air pump is installed and fixed at the rear of the fixed frame.

[0006] Furthermore, a first threaded cylinder is connected to the threaded rod via a helical drive, and limit plates are provided at both ends of the first threaded cylinder; an elongated through hole is provided on the column, through which the first threaded cylinder passes, and the limit plates are secured to the column.

[0007] Furthermore, a push handle is rotatably connected to one side of the base, and the push handle is in the shape of a zigzag line.

[0008] Furthermore, a connecting plate is embedded and fixed on the base, and a semi-circular retaining ring is supported on the connecting plate by a support plate.

[0009] Furthermore, a rotating motor is fixedly installed on one side of the fixed frame, and a first bevel gear is fixedly connected to the output end of the rotating motor. A second bevel gear meshes with one side of the first bevel gear, and a rotating rod is inserted through the center of the second bevel gear, and the two are fixedly connected.

[0010] Furthermore, a third bevel gear is fixedly connected to both ends of the rotating rod, a fourth bevel gear meshes with one side of the third bevel gear, and a lead screw is inserted through the center of the fourth bevel gear; a second threaded cylinder is fixedly connected to the sliding sleeve, and a helical transmission connection is formed between the second threaded cylinder and the lead screw.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. This utility model, by setting an adjusting rod, a threaded rod, a rotating handle, and a first threaded cylinder, rotates the threaded rod by rotating the handle, and the threaded rod and the first threaded cylinder are driven by a screw. Since the first threaded cylinder is limited in the through hole, the adjusting rod can pull the fixed frame, thereby realizing flexible adjustment of the angle of the display screen body, which is convenient for viewing.

[0013] 2. This utility model is equipped with an air pump, an air pipe, a sliding sleeve, and a rotating motor. When the air pump and the rotating motor are started simultaneously, the high-pressure gas generated by the air pump is conducted through the air pipe, and the rotating motor drives the sliding sleeve to move on the guide plate, which in turn moves the end of the air pipe to perform high-pressure spray cleaning on the surface of the display screen without damaging the screen.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] Example:

[0023] As attached Figure 1 To be continued Figure 5 As shown:

[0024] This utility model provides a multifunctional LED display screen, including a base 1 and a fixed frame 7; a pulley 2 is installed at the bottom of the base 1, a column 3 is supported above the base 1, a first rotating support rod 4 is provided at the top of the column 3, a first rotating support 5 is rotatably connected to the first rotating support rod 4, a mounting plate 6 is fixedly connected to the first rotating support 5, the mounting plate 6 is connected to the fixed frame 7 by bolts, and the display screen body 8 is installed and fixed inside the fixed frame 7; a second rotating support 9 is provided at the rear of the fixed frame 7, a second rotating support rod 10 is rotatably connected to the second rotating support 9, a rotating sleeve 11 is provided on the second rotating support rod 10, and an adjusting rod 1 is inserted through the rotating sleeve 11. 2. A rotatable connection is formed between the two. The adjusting rod 12 is provided with two sets of positioning plates 13. The rotating sleeve 11 is positioned between the two sets of positioning plates 13. One end of the adjusting rod 12 is fixedly connected to a threaded rod 14, and the central axis of the threaded rod 14 coincides with the central axis of the adjusting rod 12. One end of the adjusting rod 12 is provided with a rotating handle 15. Guide plates 23 are provided on the upper and lower sides of the fixed frame 7. A sliding sleeve 24 is slidably connected to the guide plate 23. A wire harness plate 25 is provided on the sliding sleeve 24. An air pipe 26 is inserted through the wire harness plate 25. One end of the air pipe 26 faces the display screen body 8, and the other end is connected to the air pump 27. The air pump 27 is installed and fixed at the rear of the fixed frame 7.

[0025] Among them, such as Figure 3 As shown, a first threaded cylinder 16 is connected to the threaded rod 14 via a helical drive. Limiting plates 17 are provided at both ends of the first threaded cylinder 16. A long, narrow through hole 18 is provided on the column 3, through which the first threaded cylinder 16 passes. The limiting plates 17 are then secured to the column 3. If the angle of the display screen body 8 needs to be adjusted during viewing, the threaded rod 14 can be rotated by turning the handle 15. The threaded rod 14 undergoes helical drive within the first threaded cylinder 16. The adjusting rod 12 and positioning plate 13 pull the rotating sleeve 11 and the second rotating support rod 10, which in turn drive the fixed frame 7 to rotate around the first rotating support rod 4 via the second rotating support 9, thereby adjusting the angle of the display screen body 8. During this process, in conjunction with the limiting effect of the limiting plates 17 and the through hole 18 on the first threaded cylinder 16, the first threaded cylinder 16 also moves upward or downward within the through hole 18 to adapt to changes in the height of the second rotating support 9.

[0026] Among them, such as Figure 2As shown, a push handle 19 is rotatably connected to one side of the base 1. The push handle 19 is in the shape of a zigzag line. If it is necessary to move the display screen or adjust its horizontal direction, the bottom of the push handle 19 can be placed on the base 1. With the help of the pulley 2, the entire display screen can be pushed by holding the push handle 19. A connecting plate 20 is embedded and fixed on the base 1. A semi-circular retaining ring 22 is supported on the connecting plate 20 by a support plate 21. After the display screen is moved, the pulley 2 can be locked, and then the push handle 19 can be flipped so that it rests on the semi-circular retaining ring 22, reducing the space occupied.

[0027] Among them, such as Figure 4 As shown, a rotating motor 28 is fixedly mounted on one side of the fixed frame 7. A first bevel gear 29 is fixedly connected to the output end of the rotating motor 28. A second bevel gear 30 meshes with one side of the first bevel gear 29. A rotating rod 31 is inserted through the center of the second bevel gear 30, and the two are fixedly connected. A third bevel gear 32 is fixedly connected to both ends of the rotating rod 31. A fourth bevel gear 33 meshes with one side of the third bevel gear 32. A lead screw 34 is inserted through the center of the fourth bevel gear 33. Figure 5 As shown, a second threaded cylinder 35 is fixedly connected to the sliding sleeve 24, and a helical transmission connection is formed between the second threaded cylinder 35 and the lead screw 34. When it is necessary to clean the display screen body 8, the air pump 27 can be started to generate high-pressure gas, which is transmitted through the air pipe 26. The rotating motor 28 is started, which drives the second bevel gear 30 to rotate the rotating rod 31 through the first bevel gear 29. The third bevel gear 32 drives the fourth bevel gear 33 to rotate the lead screw 34. With the guidance of the guide plate 23 for the movement of the sliding sleeve 24, the lead screw 34 helically drives the second threaded cylinder 35, and the cable tray 25 drives the air pipe 26 from one end of the guide plate 23 to the other end, and the surface of the display screen body 8 is sprayed with high-pressure gas for cleaning.

[0028] The specific usage and function of this embodiment are as follows:

[0029] In this invention, if the angle of the display screen body 8 needs to be adjusted during viewing, the threaded rod 14 can be rotated by turning the handle 15. The threaded rod 14 is spirally driven inside the first threaded cylinder 16. The rotating sleeve 11 and the second rotating support rod 10 are pulled by the adjusting rod 12 and the positioning plate 13. The fixed frame 7 is driven to rotate around the first rotating support rod 4 by the second rotating support 9, thereby realizing the adjustment of the angle of the display screen body 8. When the display screen body 8 needs to be cleaned, the air pump 27 can be started to generate high-pressure gas, which is transmitted through the air pipe 26. The rotating motor 28 is started, which drives the second bevel gear 30 to rotate the rotating rod 31 through the first bevel gear 29. The fourth bevel gear 33 is driven by the third bevel gear 32 to rotate the lead screw 34. With the guidance of the guide plate 23 for the movement of the sliding sleeve 24, the lead screw 34 spirally drives the second threaded cylinder 35. The cable tray 25 drives the air pipe 26 from one end of the guide plate 23 to the other end, and the surface of the display screen body 8 is sprayed with high-pressure gas for cleaning.
