DETAILED DESCRIPTION
[0025] The utility model will be further explained in detail in connection with the drawings. These drawings are all simplified schematic diagrams, just illustrate the basic structure of the utility model in the schematic mode, therefore it just shows the structure related to the utility model.
[0026] Reference Figures 1-4 A LED display screen with the support structure, including base 1 and display screen body 3,
[0027] The base 1 top two sides are fixedly installed with the support column 2, the support column 2 is internally provided with the sliding groove 7, the display screen body 3 both sides outer wall is fixedly installed with the slider 13, the display screen body 3 is placed in the inside of two groups of support columns 2, and the slider 13 is slidably installed in the sliding groove 7, the base 1 inside both sides bottom is fixedly installed with the servo motor 8, the servo motor 8 top output shaft is drivenly installed with the screw rod 9, and the screw rod 9 is through the base 1 rear and is installed perpendicularly in the sliding groove 7.
[0028] The slider 13 has a second screw hole 14 vertically through the center, and the lead screw 9 passes through the second screw hole 14.
[0029] In this embodiment, when it is necessary to adjust the height of the display screen body 3, the servo motor 8 is started, and the servo motor 8 drives the lead screw 9 to rotate. Since the slider 13 and the lead screw 9 are connected by a thread through the second screw hole 14, and the slider 13 is restricted to slide up and down in the slide groove 7 of the support column 2, the rotation of the lead screw 9 will drive the slider 13 to move up and down along the slide groove 7, thereby driving the display screen body 3 to achieve height adjustment.
[0030] refer to Figures 1-4 The base 1 has movable seats 4 installed on both sides of the inner wall. The movable seat 4 has a first screw hole 12 vertically through the center of the interior. The screw rod 9 passes through the first screw hole 12. The movable seat 4 has support arms 5 movably installed on both the front and rear sides through the pivot.
[0031] Specifically, the outer sides of the two sets of movable seats 4 are in contact with the inner sides of the base 1, and the contact area between the side wall of the movable seat 4 and the inner wall of the base 1 is provided with a wear-resistant coating to reduce friction.
[0032] Among them, a rotating shaft seat 10 is fixedly installed on both sides of the lower part of the front and rear outer walls of the base 1. A folding arm 11 is movably installed in the rotating shaft seat 10 through a rotating shaft. The other end of the folding arm 11 is movably connected to the support arm 5 through a rotating shaft.
[0033] Specifically, damping devices are provided at the connection points of the folding arm 11 with the pivot seat 10 and the support arm 5, so that the folding arm 11 can maintain a stable state after the angle is adjusted.
[0034] Secondly, rollers 6 are movably installed at the bottom of the support arm 5;
[0035] Specifically, roller 6 is made of rubber and has anti-slip textures on its surface to enhance friction with the ground.
[0036] In addition, the outer walls of the front and rear sides of the base 1 are perforated with holes 15, and the front and rear ends of the movable seat 4 pass through the holes 15.
[0037] In this embodiment, the movable seat 4 can only move along the axial direction of the screw rod 9 under the limit of the through hole 15, and the wear-resistant coating of the contact part between the movable seat 4 and the inner wall of the base 1 effectively reduces the friction resistance, thereby ensuring the smoothness of the movement. When the display screen body 3 is lifted, the support arm 5 will be unfolded or folded according to the connection relationship between the support arm 5 and the movable seat 4, and the folding arm 11 is connected with the support arm 5 and the pivot seat 10 on one side and can be kept stable at a suitable angle by means of the damping device at the pivot thereof on the other side, thereby providing stable and reliable support for the display screen body 3 together with the support arm 5, preventing the display screen body 3 from shaking or toppling over. The rollers 6 at the bottom can assist the support arm 5 to slide during the movement of the support arm 5, and the rubber material and the anti-skid pattern ensure sufficient friction between the support arm 5 and the ground, thereby avoiding accidental sliding of the support structure.
[0038] It is worth mentioning that the threads on the upper and lower outer walls of the screw rod 9 are opposite, and the upper and lower opposite threads are respectively engaged with the inner wall threads of the second screw hole 14 and the first screw hole 12.
[0039] Specifically, the threads on the upper and lower outer walls of the screw rod 9 are opposite, so that when the screw rod 9 rotates clockwise, the opposite threads on the two sides are respectively located in the second screw hole 14 and the first screw hole 12, at this time, the sliding block 13 is pushed to move upward, and the movable seat 4 moves downward in the opposite direction. When the screw rod 9 rotates counterclockwise, the sliding block 13 is driven to move downward, and the movable seat 4 moves upward.
[0040] Working principle: when it is necessary to lift the display screen body 3, the servo motor 8 is started to rotate clockwise, and the screw rod 9 rotates clockwise accordingly. Since the threads on the upper and lower outer walls of the screw rod 9 are opposite, and the upper thread is engaged with the inner wall thread of the second screw hole 14 of the sliding block 13, and the lower thread is engaged with the inner wall thread of the first screw hole 12 of the movable seat 4, under the action of the thread transmission, the sliding block 13 moves upward along the screw rod 9, and the movable seat 4 moves downward along the screw rod 9. The sliding block 13 drives the display screen body 3 to stably rise in the sliding groove 7 of the support column 2, and the downward movement of the movable seat 4 drives the support arm 5 connected thereto to rotate through the pivot, and the rollers 6 at the bottom end of the support arm 5 slide on the ground, and the folding arm 11 also rotates flexibly around the connection pivot between the folding arm 11, the pivot seat 10 and the support arm 5, and is quickly stabilized at a suitable angle under the action of the damping device, thereby providing continuous and stable lateral support for the display screen body 3 during the rising process together with the support arm 5, so as to ensure that the display screen body 3 does not tilt or shake. Conversely, when it is necessary to lower the display screen body 3, the servo motor 8 rotates counterclockwise, and the screw rod 9 rotates counterclockwise accordingly. At this time, the sliding block 13 moves downward, and the movable seat 4 moves upward. The support arm 5, the folding arm 11 and the rollers 6 also operate according to the above linkage principle to ensure that the display screen body 3 descends stably, and the entire LED display screen can always work stably at different heights.
[0041] It can be understood that the servo motor and the display screen body driving mode in the utility model can be driven in the mode of external power line, the servo motor and the display screen body can be programmed and controlled by the master control system, and the control principle is realized by the existing control technology. The model of the servo motor and the display screen body is not limited to a single type and can be the existing type suitable for the utility model in the market.
[0042] The above merely describes a preferred specific implementation manner of the utility model, but the protection scope of the utility model is not limited to this, any skilled person in the art can make equivalent replacement or change according to the technical scheme and the utility model concept of the utility model within the technical range disclosed by the utility model, and all should be covered in the protection scope of the utility model.
