Description

Technical Field

[0001] This utility model relates to the field of LED display technology, and in particular to a conveniently adjustable LED display. Background Technology

[0002] An LED display screen is a display method that controls semiconductor light-emitting diodes to display various information such as text, graphics, images, animations, videos, and recorded signals. It consists of many light-emitting diodes, usually red, green, and blue, and displays characters by turning the lights on and off.

[0003] Traditional LED displays are typically fixed installations, securely mounted on walls or placed on furniture using wall mounts or bases. Once the angle is determined, it is difficult to adjust. Viewers must adapt to the screen's position, rather than the screen adapting to the viewer. This limitation can easily lead to undesirable viewing angles and distances, and prolonged viewing may cause neck and eye discomfort. For family members with different viewing needs or multi-purpose rooms, the lack of flexibility reduces the overall user experience and convenience.

[0004] Therefore, it is necessary to design an easily adjustable LED display screen to solve the above-mentioned technical problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional LED displays, such as fixed angle, inconvenient viewing, lack of flexibility, and reduced user experience and convenience, the purpose of this utility model is to provide an LED display that is easy to adjust.

[0006] Technical Solution: A conveniently adjustable LED display screen includes a display screen, a camera, a protective film, a hinge block, a bracket, a turntable, a mounting base, first screws, limit rings, and nuts. A camera is fixedly connected to the upper part of the display screen, a protective film is fixedly connected to the front part of the display screen, and a hinge block is fixedly connected to the rear part of the display screen. A bracket is rotatably sleeved in the middle of the hinge block, a turntable is rotatably connected to the lower part of the bracket, and a mounting base is rotatably connected to the bottom of the turntable. First screws are inserted into the hinge block and the turntable, and the two first screws are located inside the bracket. Limit rings are threadedly connected to one end of each of the two first screws, and nuts are fixedly connected to the ends of the two first screws that protrude from the turntable.

[0007] Furthermore, it is particularly preferred that the left side of the bracket has a symmetrical annular array of multiple grooves, and the right side of the two limiting rings has a annular array of multiple protrusions. Each groove on the bracket engages with each protrusion on the two limiting rings. The left side of the two limiting rings is fixed with multiple guide blocks, and the lower part of the hinge block and the upper part of the turntable are both provided with multiple snap-fit ​​grooves. Each limiting block slides in the corresponding snap-fit ​​groove.

[0008] Furthermore, it is particularly preferred that the plate also includes an indexing plate, a telescopic rod, and a stud. The indexing plate is fixedly connected to the bottom of the turntable and rotates inside the mounting base. The telescopic rod is slidably connected inside the mounting base, and the stud is threadedly connected inside the mounting base. The stud is rotatably connected to the telescopic rod. A snap-fit ​​plate is fixedly sleeved on the lower part of the indexing plate and engages with the telescopic rod.

[0009] Furthermore, it is particularly preferred that the device also includes a guide frame, a cleaning block, an elastic element, a fixed pulley, a pull rope, and a handle. The guide frames are symmetrically fixedly connected to the front of the display screen. The cleaning block is slidably connected between the two guide frames. An elastic element is connected between the cleaning block and the two guide frames. A fixed pulley is rotatably connected to the top of one guide frame. A pull rope is fixedly connected to the top of the cleaning block. The pull rope passes through the guide frame on the right side and is wound around the fixed pulley. The other end of the pull rope is fixedly connected to the top of the handle.

The turntable 4 is rotatably connected to the lower part of the bracket 3. The mounting base 5 is rotatably connected to the bottom of the turntable 4. First screws 8 are inserted into the hinge block 2 and the turntable 4 respectively. 8 is located inside the bracket 3. The two first screws 8 pass through the right end of the bracket 3 and are threadedly connected to the limiting rings 7. The left side of the bracket 3 is symmetrically arranged with multiple grooves in a ring array. The right side of the two limiting rings 7 is arranged with multiple protrusions in a ring array. Each groove on the bracket 3 meshes with each protrusion on the two limiting rings 7. Three guide blocks are fixedly provided on the left side of the two limiting rings 7. The lower left side of the hinge block 2 and the upper left side of the turntable 4 are each provided with three snap-fit ​​grooves. Each limiting block slides in the corresponding snap-fit ​​groove. Nuts 6 are welded to one end of each of the two first screws 8 that pass through the turntable 4.

[0024] like Figure 1 and Figure 5 As shown, it also includes an indexing plate 9, a telescopic rod 10, and a stud 11. The indexing plate 9 is fused to the bottom of the turntable 4 and rotates inside the mounting base 5. The telescopic rod 10 is slidably connected to the left side inside the mounting base 5, and the stud 11 is threadedly connected to the left side inside the mounting base 5. The stud 11 is rotatably connected to the telescopic rod 10. A snap-fit ​​plate is fixedly sleeved on the lower outer side of the indexing plate 9 and snaps into the telescopic rod 10.

[0025] like Figure 1 and Figure 6 As shown, it also includes a guide frame 12, a cleaning block 13, an elastic element 14, a fixed pulley 15, a pull rope 16, a handle 161, and a rubber block 17. The guide frames 12 are symmetrically installed on the left and right sides of the front of the display screen 1 by screws. The cleaning block 13 is slidably connected between the two guide frames 12. The elastic element 14 is connected between the cleaning block 13 and the two guide frames 12. The fixed pulley 15 is rotatably connected to the top of the guide frame 12 on the right side of the display screen 1. The pull rope 16 is welded to the top right side of the cleaning block 13.

After adjustment, the operator rotates the stud 11 counterclockwise to move the telescopic rod 10 to the right and re-engage it with the indexing plate 9, ensuring that the turntable 4 is accurately positioned and locked at each rotation angle to prevent accidental movement. When the tilt angle of the display screen 1 needs to be adjusted, the operator rotates the two nuts 6 clockwise to move the limit block to the left and slide it in the locking groove. At this time, the protrusion and... When the groove disengages, the bracket 3 becomes loose. Then, the bracket 3 is rotated to change the tilt angle of the display screen 1. After adjustment, the nut 6 is turned counterclockwise to tighten it, causing the first screw 8 to rotate. At this time, the limit block moves to the right and slides in the locking groove. The protrusion engages with the groove, keeping the adjusted angle unchanged. When it is necessary to clean the desktop of the display screen 1, the operator pulls the handle 161 downwards. The pull rope 16 is guided by the fixed pulley 15, causing the cleaning block 13 to slide upwards along the guide frame 12. The elastic element 14 is compressed to its limit, thereby wiping away the dust and stains on the display screen 1. The handle 161 is released, and under the restoring force of the elastic element 14, the cleaning block 13 returns to its original position. The elastic element 14 is compressed and reset, achieving efficient cleaning. When it is necessary to move and disassemble the equipment, the operator loosens the nut 18 counterclockwise to detach the suction cup 20 from the desktop, so that the equipment can be moved and disassembled.
