Description

Technical Field

[0001] This utility model relates to the field of display screen technology, specifically a multi-level intelligent LED display screen. Background Technology

[0002] LED electronic displays are a type of display that uses controlled semiconductor light-emitting diodes (LEDs). They consist of tens of thousands to hundreds of thousands of LED pixels arranged uniformly. By using different materials, LED pixels of different colors can be manufactured to display various information such as text, graphics, images, animations, market information, videos, and recorded signals. They are widely used in shopping malls, plazas, exhibitions, concerts, and other venues.

[0003] When supermarkets and shopping malls use LED displays as advertising equipment, they usually use embedded splicing screens, which involve splicing multiple LED displays into the wall to form a large screen for displaying advertisements and other information.

[0004] However, because this type of display screen is embedded inside the wall, its sides and back are blocked by the building structure during subsequent inspection and maintenance. Furthermore, the surface of the display screen is relatively fragile, making disassembly and assembly operations very cumbersome. Utility Model Content

[0005] Therefore, the purpose of this utility model is to provide a multi-level intelligent LED display screen to solve the technical problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a multi-level intelligent LED display screen, including a wall and a vertical frame, a fixed seat fixed to the back of the vertical frame, and a movable seat penetrating the outer surface of the fixed seat, with a first spring connected inside the movable seat; a groove is provided on the upper back of the movable seat, a limiting block and a traction block are respectively connected to the upper inside of the fixed seat, and a cable is connected between the limiting block and the traction block, with a second spring connected between the limiting block and the fixed seat.

[0007] By employing the above technical solution, workers push the display screen body into the wall, while the movable seat retracts into the fixed seat. Then, the shapes of the abutment groove and the limiting block cause the abutment groove to push the limiting block upwards, preventing the limiting block from obstructing the retraction of the movable seat. After the limiting block moves upwards, it compresses the second spring. Once the display screen body is inside the wall, the movable seat retracts into the fixed seat. At this point, the second spring loses pressure, driving the limiting block downwards, thus causing the limiting block to abut against the outer surface of the movable seat, preventing the movable seat and the display screen body from shifting outwards. When it is necessary to disassemble the display screen body, workers simply attach a strong magnet to the outer surface of the display screen body. The rear traction block is displaced due to magnetic influence; after the traction block moves forward, it pulls the limiting block through the cable, causing the limiting block to move upward and stop limiting the movable seat; then the first spring can push the movable seat to move, causing the display screen body to automatically extend out of the wall; at the same time, the T-shaped cross-section of the movable seat can prevent the movable seat from sliding out of the fixed seat, firstly to avoid the structure falling off and causing the display screen body to fall to the ground and get injured, and secondly to avoid the cable of the display screen body being torn due to the long travel; after the display screen body extends out of the wall, the staff can inspect and replace the cable at the back of the display screen body, or remove the bolts to inspect and replace the display screen body.

[0008] Furthermore, pulleys are connected to both the top and bottom of the fixed base, and the cable is in contact with the pulleys.

[0009] By adopting the above technical solution, the presence of the pulley facilitates changing the direction of the force transmitted by the cable, transforming the force of the traction rope moving back and forth into the force of the limit block moving up and down, and reducing the wear on the cable.

[0010] Furthermore, the cable is a single-twist steel wire rope.

[0011] By adopting the above technical solution, the single-twist steel wire rope has strong structural strength and tensile strength, which makes it easy to limit the structure by pulling the limit block with the cable when the traction block is displaced.

[0012] Furthermore, the movable seat has a "T" shaped cross-section, and the movable seat is slidably connected to the fixed seat.

[0013] By adopting the above technical solution, the T-shaped cross-section of the movable seat can prevent the movable seat from sliding out of the fixed seat. This prevents the structure from falling off and injuring the display screen body, and also prevents the cables of the display screen body from being torn due to the long travel distance.

[0014] Furthermore, the groove is sloping, and the lower part of the outer surface of the limiting block is rounded.

[0015] By adopting the above technical solution, the movable seat retracts into the fixed seat, and then the shape of the abutment groove and the limiting block causes the abutment groove to push the limiting block upward, thus preventing the limiting block from blocking the retraction of the movable seat.

[0016] Furthermore, the abutment groove abuts against the limiting block, and the limiting block abuts against the movable seat.

[0017] By adopting the above technical solution, the movable seat retracts into the fixed seat; then, through the shape of the abutment groove and the limiting block, the abutment groove pushes the limiting block upward. When the display screen body enters the wall, the second spring loses pressure and drives the limiting block downward, thereby causing the limiting block to abut against the outer surface of the movable seat, preventing the movable seat and the display screen body from shifting outward.

[0018] Furthermore, the traction block is made of iron or magnet, and both the traction block and the limiting block are slidably connected to the fixed base.

[0019] By adopting the above technical solution, the staff only need to attach a strong magnet to the outer surface of the display screen body, and after the traction block moves forward, the limit block is pulled by the cable.

[0020] Furthermore, vertical and horizontal frames are connected inside the wall, a display screen body is installed on the outer surface of the movable seat, and bolts connect the display screen body to the movable seat. A light sensor is installed above the inside of the wall.

[0021] By adopting the above technical solution, workers then fix the vertical frame, horizontal frame, and mounting base into the wall using rivets or welding. Workers connect the main display screen to the movable base using bolts, and then push the main display screen into the wall. Multiple main display screens are then spliced ​​together to form a large display screen, which can display and disseminate information about shops, products, and safety content within the supermarket in the form of images or videos. Simultaneously, a light sensor monitors the ambient light. The controller of the main display screen automatically adjusts the brightness level of the main display screen according to the monitoring structure of the light sensor, corresponding to the brightness of the ambient light. If the ambient light is dim, the brightness of the main display screen automatically adjusts to a dimmer level to avoid excessive brightness affecting the vision of surrounding people; conversely, when the ambient light is bright, the brightness of the main display screen automatically adjusts to a brighter level to prevent strong ambient light from making it difficult for surrounding people to see the content displayed on the main display screen. This is quite intelligent.

[0022] Furthermore, the back of the wall is connected to a building column, and the top of the building column is connected to a building beam.

[0023] By adopting the above technical solution, workers construct walls using wooden frames and plasterboard, connecting them to building columns and beams, and then decorating them with paint according to the style of the surrounding environment, thus creating a more aesthetically pleasing overall structure.

[0024] In summary, the present invention has the following main advantages:

[0025] 1. This utility model, through the arrangement of a fixed base, a movable base, and a first spring, allows the movable base to slide inside the fixed base, facilitating the retraction and extension of the display screen body into and out of the wall. Simultaneously, the first spring ensures that the movable base automatically extends out of the wall after reaching its limit position, allowing workers to easily operate the bolts for assembly and disassembly. Furthermore, the T-shaped cross-section of the movable base prevents it from sliding out of the fixed base, thus preventing structural detachment and the display screen body from falling to the ground and causing injury, and also preventing the cables of the display screen body from being broken due to excessive travel. This design facilitates the disassembly, repair, or replacement of the display screen body and offers a high level of safety.

[0026] 2. This utility model, through the arrangement of a retaining groove, a limiting block, a second spring, a cable, and a traction block, allows the movable seat to retract into the fixed seat when the display screen body is pushed into the wall. At this time, the shape of the retaining groove and the limiting block causes the retaining groove to push the limiting block upward, preventing the limiting block from obstructing the retraction of the movable seat. After the limiting block moves upward, it compresses the second spring. When the display screen body enters the wall, the movable seat retracts into the fixed seat. At this time, the second spring loses pressure and drives the limiting block downward, thereby causing the limiting block to abut against the outer surface of the movable seat, preventing the movable seat and the display screen body from shifting outward. When it is necessary to disassemble the display screen body, simply attach a strong magnet to the outer surface of the display screen body, causing the traction block behind the display screen body to shift due to magnetic influence. After the traction block shifts forward, it pulls the limiting block through the cable, causing the limiting block to move upward and stop limiting the movable seat. Then, the first spring can push the movable seat to move, allowing the display screen body to automatically extend out of the wall. The operation is simple and convenient, and the hidden structure is not easily discovered, thus increasing aesthetics and safety. Attached Figure Description

[0032] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0033] The embodiments of this utility model will be described below based on its overall structure.

[0034] Example 1:

[0035] A multi-level intelligent LED display screen, such as Figures 2-4 As shown, the structure includes a wall 1 and a vertical frame 4. A fixed seat 8 is fixed to the back of the vertical frame 4. A movable seat 9 penetrates the outer surface of the fixed seat 8. The movable seat 9 has a "T"-shaped cross-section and is slidably connected to the fixed seat 8. A first spring 11 is connected inside the movable seat 9. A groove 12 is formed on the upper back of the movable seat 9. The groove 12 is sloping. A limit block 13 and a traction block 16 are connected to the upper interior of the fixed seat 8. The lower part of the outer surface of the limit block 13 is rounded. The groove 12 abuts against the limit block 13, and the limit block 13 abuts against the movable seat 9. The traction block 16 is made of iron. Made of materials or magnets, the traction block 16 and the limiting block 13 are slidably connected to the fixed base 8. A cable 15, which is a single-twist steel wire rope, connects the limiting block 13 and the traction block 16. A second spring 14 connects the limiting block 13 and the fixed base 8. When the operator pushes the display screen body 6 into the wall 1, the movable base 9 retracts into the fixed base 8. Then, due to the shapes of the groove 12 and the limiting block 13, the groove 12 pushes the limiting block 13 upward, preventing the limiting block 13 from blocking the retraction of the movable base 9. After the limiting block 13 moves upward, it compresses the second spring 14. When the display screen body 6 enters the wall 1, the movable seat 9 retracts into the fixed seat 8. At this time, the second spring 14 loses pressure and drives the limiting block 13 to move downward, thereby causing the limiting block 13 to abut against the outer surface of the movable seat 9, preventing the movable seat 9 and the display screen body 6 from moving outward. When it is necessary to disassemble the display screen body 6, the operator only needs to attach a strong magnet to the outer surface of the display screen body 6, causing the traction block 16 behind the display screen body 6 to be displaced by the magnet. After the traction block 16 moves forward, it pulls the limiting block 13 through the cable 15, causing the limiting block 13 to move upward and ending the disassembly. The movable seat 9 is then positioned; subsequently, the first spring 11 pushes the movable seat 9 to move, causing the display screen body 6 to automatically extend from the wall 1. At the same time, the T-shaped cross-section of the movable seat 9 prevents it from sliding out of the fixed seat 8, thus preventing the structure from falling and injuring the display screen body 6, and also preventing the cables of the display screen body 6 from being torn due to the long travel distance. After the display screen body 6 extends from the wall 1, the staff can inspect and replace the cables behind the display screen body 6, or remove the bolts 10 to inspect and replace the display screen body 6.

[0036] See Figures 1-4 In the above embodiment, a vertical frame 4 and a horizontal frame 5 are connected inside the wall 1. A display screen body 6 is installed on the outer surface of the movable base 9. Bolts 10 connect the display screen body 6 and the movable base 9. A light sensor 7 is installed at the top inside the wall 1. A building column 2 is connected to the back of the wall 1. A building beam 3 is connected to the top of the building column 2. Workers construct the wall 1 using a wooden frame and plasterboard, and connect it to the building column 2 and the building beam 3. They then decorate it with paint according to the style of the surrounding environment to create a more aesthetically pleasing overall structure. Afterwards, workers fix the vertical frame 4, horizontal frame 5, and fixed base 8 by riveting or welding and then install them into the wall 1. Workers connect the display screen body 6 to the movable base 9 using bolts 10. Finally, workers push the display screen body 6... Inside the wall 1, multiple display screens 6 are spliced ​​together to form a large display screen, which can display and disseminate information such as shops, products, and safety content in the supermarket in the form of images or videos. At the same time, the ambient light is monitored by the light sensor 7. Then, the controller of the display screen 6 automatically adjusts the brightness level of the display screen 6 according to the monitoring structure of the light sensor 7, corresponding to the brightness of the ambient light. If the ambient light is dim, the brightness of the display screen 6 is automatically adjusted to a dimmer level to avoid the brightness of the display screen 6 being too high and affecting the vision of the surrounding people. Conversely, when the ambient light is bright, the brightness of the display screen 6 is automatically adjusted to a brighter level to avoid the ambient light being too strong and the surrounding people not being able to see the content displayed on the display screen 6. It is quite intelligent.

[0037] Example 2:

[0038] Based on the above embodiment one, the following settings are now adopted to increase the stability of the structure.

[0039] See Figure 3 and Figure 4 In the above embodiment, pulleys 17 are connected to the top and bottom of the fixed base 8. The cable 15 is in contact with the pulleys 17. The presence of the pulleys 17 facilitates changing the direction of the force transmitted by the cable 15, converting the force of the traction rope moving back and forth into the force of the limit block 13 moving up and down, and reducing the wear on the cable 15.

[0040] The implementation principle of this utility model is as follows: First, the workers construct the wall 1 using a wooden frame and gypsum board, and connect it with the building columns 2 and building beams 3. They then select paint to decorate it according to the style of the surrounding environment, thus forming a more aesthetically pleasing whole. Afterwards, the workers fix the vertical frame 4, horizontal frame 5, and fixing seat 8 by means of rivets or welding, and then install them into the wall 1 for fixation.

[0041] Workers connect the display body 6 to the movable seat 9 using bolts 10. Then, they push the display body 6 into the wall 1, while the movable seat 9 retracts into the fixed seat 8. The shapes of the abutment groove 12 and the limiting block 13 cause the abutment groove 12 to push the limiting block 13 upward, preventing the limiting block 13 from blocking the retraction of the movable seat 9. After the limiting block 13 moves upward, it compresses the second spring 14. When the display body 6 enters the wall 1, the movable seat 9 retracts into the fixed seat 8. At this time, the second spring 14 loses pressure and drives the limiting block 13 downward, so that the limiting block 13 abuts against the outer surface of the movable seat 9, preventing the movable seat 9 and the display body 6 from moving outward.

[0042] Multiple display screens 6 are spliced ​​together to form a large display screen, which can display and disseminate information such as store information, products, and safety content in supermarkets and shopping malls in the form of images or videos. At the same time, the ambient light is monitored by a light sensor 7, and then the controller of the display screen 6 automatically adjusts the brightness level of the display screen 6 according to the monitoring structure of the light sensor 7 to correspond to the brightness of the ambient light. If the ambient light is dim, the brightness of the display screen 6 is automatically adjusted to a dimmer level to avoid the brightness of the display screen 6 being too high and affecting the vision of the people around. Conversely, when the ambient light is bright, the brightness of the display screen 6 is automatically adjusted to a brighter level to avoid the ambient light being too strong and making it difficult for the people around to see the content displayed on the display screen 6. It is quite intelligent.

[0043] When it is necessary to disassemble the display screen body 6, the operator only needs to attach a strong magnet to the outer surface of the display screen body 6. Since there is no part of the LED display screen that can be attached, the magnetism of the strong magnet has no effect on the display screen body 6. Instead, it causes the traction block 16 behind the display screen body 6 to be displaced by the magnetism. After the traction block 16 moves forward, it pulls the limiting block 13 through the cable 15, causing the limiting block 13 to move upward and stop limiting the movable seat 9. At the same time, since the fixed seat 8 is equipped with a pulley 17, the presence of the pulley 17 makes it easy to change the direction of the force transmitted by the cable 15, converting the force of the traction rope moving back and forth into the limiting block. The force of the up-and-down movement of the 13 reduces the wear on the cable 15; then the first spring 11 can push the movable seat 9 to move, so that the display body 6 can automatically extend out of the wall 1; at the same time, the cross-section of the movable seat 9 is T-shaped, which can prevent the movable seat 9 from sliding out of the fixed seat 8, firstly to avoid the structure falling off and causing the display body 6 to fall to the ground and get injured, and secondly to avoid the cable of the display body 6 being torn due to the long stroke; after the display body 6 extends out of the wall 1, the staff can inspect and replace the cable behind the display body 6, or remove the bolt 10 to inspect and replace the display body 6.
