Description

Technical Field

[0001] The utility model relates to the technical field of LED display screens, in particular to an LED display screen which can rotate 360 ​​degrees. Background Art

[0002] As a desktop LED display device for advertising display, it is widely used in businesses due to its good display effect. Its main structure includes a base and an LED display screen that can display text or patterns. During application, it is placed in the display area through the base.

[0003] However, the following problems still exist in actual use:

[0004] (1) The existing display and the back cover are tightly attached to each other without installing bolts or screws. Therefore, when the user lifts the display screen from the back cover, it is difficult to separate the two by hand. Therefore, the user uses tools to lift the display screen. In this way, the force is concentrated during lifting, which can easily cause damage to the display screen, making the entire disassembly process very troublesome.

[0005] (2) Due to structural limitations, existing LED display screens can generally only be used for static display, that is, the display screen cannot be rotated at multiple angles, so its display interface can only face customers in one direction, and accordingly cannot achieve a good display effect. Utility Model Content

[0006] In view of the deficiencies in the prior art, the utility model provides a 360-degree rotatable LED display screen, which can be quickly installed and disassembled to prevent damage to the back shell of the display screen caused by disassembly using tools. In addition, the angle of the display screen can be adjusted in multiple directions to facilitate display to customers in multiple locations, thereby solving the problems raised in the background technology.

[0007] The utility model provides the following technical solution: an LED display screen that can rotate 360 ​​degrees, comprising: a main body, a fixing mechanism is arranged on the surface of the main body, the fixing mechanism comprises: a bidirectional screw, a first support block is threadedly connected to the outer edge of the bidirectional screw, a second support block is fixedly installed on the side of the first support block, support strips are hinged on both sides of the inner wall of the second support block, third support blocks are hinged on both sides of the support strips, a connecting plate is fixedly installed on the side of the third support block, a limiting block is fixedly installed on the side of the connecting plate, a clamping plate is fixedly installed on the side of the limiting block, and a display screen body is fixedly installed on the side of the clamping plate.

[0009] Preferably, the outer edge of the bidirectional screw rod is rotatably connected to the inner wall of the main body, and a turning handle is fixedly mounted on one end of the bidirectional screw rod.

[0010] Preferably, a guide rod is fixedly mounted on the side surface of the inner wall of the main body, and the outer edge of the guide rod is slidably connected to the inner wall of the first support block.

[0011] Preferably, the top of the connecting block is fixedly connected to the bottom of the main body, a motor is fixedly mounted on the side of the first fixed block, a worm is fixedly mounted on the output end of the motor, and an outer edge of the worm is movably connected to an outer edge of the worm wheel.

[0012] Preferably, a bracket is fixedly installed on the top of the base plate, a rotating shaft is rotatably installed on the inner wall of the bracket, a first gear is fixedly installed on one end of the rotating shaft, a gear ring is fixedly installed on the outer edge of the turntable, and the outer edge of the gear ring is meshed with the outer edge of the first gear.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The LED display screen which can rotate 360 ​​degrees drives the two-way screw rod to rotate by turning the handle, thereby drives the first support block to slide on the outer edge of the guide rod, drives the second support block to move by the first support block, thereby drives the support bar angle adjustment, drives the third support block to move by the support bar, thereby drives the connecting plate to move, drives the limit block to move by the connecting plate to fix and disassemble the clamping plate, thereby realizing the installation and disassembly of the display screen body. The setting of this structure can effectively and quickly install and disassemble the display screen, and prevent the use of tools to disassemble and cause the back shell of the display screen to be damaged, thereby achieving the problem that the existing display and the back cover are tightly attached when there are no installation bolts or screws, so that when the user buckles the display screen from the back cover, it is difficult to separate the two by hand, so the display screen is tilted by tools, which is easy to cause damage to the display screen due to the concentrated force during tilting, and then the whole disassembly process is very troublesome.

[0015] 2. The LED display screen which can rotate 360 ​​degrees drives the first gear to rotate by rotating the rotating shaft, thereby drives the gear ring to rotate, drives the turntable to rotate by the gear ring, thereby drives the first fixed block to rotate, drives the rotating rod and the connecting block to rotate by the first fixed block, thereby drives the main body to rotate, drives the worm to rotate by the operation of the motor, thereby drives the worm wheel to rotate, so that the rotating rod drives the connecting block to adjust the angle, thereby drives the main body to adjust the angle, and the angle of the display screen can be adjusted by adjusting the main body. The setting of this structure can effectively adjust the angle of the display screen in multiple directions to facilitate display to customers in multiple positions, thereby solving the problem that the existing LED display screen can generally only be used as a static display due to structural limitations, that is, the display screen cannot achieve multi-angle rotation, so that its display interface can only face customers in one direction, and correspondingly cannot achieve a good display effect.
