DETAILED DESCRIPTION

[0029] See also Figure 1-6 In an embodiment of the present invention, an adjustment device based on a special-shaped LED display screen includes a bottom plate 1, a base 5 is fixedly connected to the bottom plate 1, sliding support rods 2 are symmetrically transmission-connected on both sides of the base 5, a cover shell 3 is installed on the sliding support rod 2, a plurality of guide clamping assemblies are provided in the cover shell 3, an elastic kit 4 is elastically connected in the sliding support rod 2, a pipe connected to the guide clamping assembly is provided in the sliding support rod 2 and the cover shell 3, when the sliding support rod 2 moves relative to the base 5, the guide clamping assembly and the cover shell 3 are elastically slidably matched, when the relative positions of the sliding support rod 2 and the base 5 are fixed, the position between the guide clamping assembly and the cover shell 3 is relatively fixed.

[0030] When in use, the edge of the special-shaped LED display screen can contact with multiple groups of guide clamping components, and the sliding support rods 2 on both sides can move toward one side of the base 5 respectively. The guide clamping components contact and abut against the edges of the special-shaped LED display screen, and then multiple guide clamping components can adaptively slide relative to the cover shell 3 according to the edge curve of the special-shaped LED display screen. When moving to the limit, that is, all the guide clamping components abut against the edges of the special-shaped LED display screen, the sliding support rods 2 are stopped from moving toward the base 5. At this time, the elastic kit 4 can block the pipeline opening, so that the guide clamping components can no longer move relative to the cover shell 3. In this way, the clamping limit that is adaptive to the edge of the special-shaped LED display screen can be achieved. Compared with conventional clamping, the clamping is more stable and more convenient for operators to adjust and trim the special-shaped LED display screen. This clamping method is also more stable than conventional elastic clamping, and more soothing than conventional rigid clamping, and is not easy to be damaged. This clamping limit method is safer and more efficient.

[0031] Among them, Figure 1-Figure 5 As shown, driving rods 52 are symmetrically and rotatably connected on both sides of the base 5, and the driving rods 52 are movably connected to the elastic kit 4 through threaded cooperation. Guide rods 51 are slidably embedded on both sides of the base 5 above the driving rods 52, and the guide rods 51 are fixedly connected to the sliding support rod 2. In this way, after the motor is connected to the end of the driving rod 52, the driving rod 52 can be driven to rotate, thereby driving the sliding support rod 2 to be relatively close to or away from the base 5. The base 5 is convenient for placing special-shaped LED display screens, thereby facilitating the guide clamping components on both sides to clamp and fix the special-shaped LED display screens.

[0032] Among them, the lower surface of the cover shell 3 is open, and the opposite end sides of the two cover shells 3 are both opened, the pipeline includes a second air guide pipeline 31 embedded in the connection between the cover shell 3 and the sliding support rod 2, and a first air guide pipeline 24 embedded in the sliding support rod 2, and multiple groups of third guide grooves 33 are embedded on the upper side of the cover shell 3, the guide clamping assembly is slidably adapted to the third guide groove 33, and a spring is also connected between the guide clamping assembly and the inner wall of the third guide groove 33, and a third air guide pipeline 32 connected with the second air guide pipeline 31 is embedded at the inner side of the cover shell 3 opposite to the third guide groove 33, and the third air guide pipeline 32 is connected to the guide clamping assembly.

[0033] When used in this way, the spring pushes the guide clamping assembly out of the cover shell 3, the openings of the cover shell 3 are opposite, and the lower opening fits the surface of the base 5. When the guide clamping assembly contacts the edge of the special-shaped LED display screen, it will slide relatively into the cover shell 3 after being subjected to force. After the sliding support rod 2 stops approaching the base 5, the elastic kit 4 blocks the port of the first air duct 24 away from the second air duct 31, and the guide clamping assembly can no longer move into the cover shell 3. In this way, the compatibility of the elastic clamping and stable clamping of the guide clamping assembly can be achieved.

[0034] Preferably, an air pipe 35 is connected to the third air guide duct 32, and the air pipe 35 extends along the extension direction of the third guide slot 33. The guide clamping assembly includes a slide bar 36 with a strip structure, and a second slider 38 is fixedly connected to the upper end of the slide bar 36 near the cover shell 3, and the second slider 38 is slidably matched with the third guide slot 33. Guide rails 34 slidably matched with the second slider 38 are symmetrically arranged on both sides of the third guide slot 33. A blind hole 37 is embedded in one end of the slide bar 36 near the cover shell 3, and the blind hole 37 is slidably matched with the air pipe 35. A rubber pad is inlaid at the end of the slide bar 36 away from the cover shell 3. In this way, when the sliding support rod 2 and the cover 3 synchronously drive the slide bar 36 to move toward the base 5, the end of the slide bar 36 can gradually contact the edge of the special-shaped LED display screen, and then the second slider 38 on the slide bar 36 slides on the third guide slot 33, the spring is gradually squeezed, and the air in the blind hole 37 is gradually discharged through the third guide slot 33, the second air duct 31 and the first air duct 24. When the first air duct 24 is blocked, the air in the blind hole 37 cannot be exhausted, so the position of the slide bar 36 and the cover 3 will be relatively limited, and the cooperation of the blind hole 37 and the air pipe 35 will also form a pneumatic vibration reduction structure, which is stable and safer. The end of the air pipe 35 preferably has a piston ring to avoid air leakage, and the cooperation of the guide rail 34 and the side of the second slider 38 is also convenient to avoid falling off, and the guidance is also more stable.

[0035] like Figure 6-10As shown, the sliding support rod 2 includes a rod body 21, a first slider 22 is fixedly connected to the lower end of the rod body 21, a first guide slot 11 slidably adapted to the first slider 22 is embedded in the upper end of the bottom plate 1, the first guide slot 11 extends from the sliding support rod 2 to one side of the base 5, the first air guide duct 24 is embedded in the rod body 21, an end hole 25 is embedded in the outer periphery of the lower end opening of the first air guide duct 24, a one-way sealing plug 28 is elastically connected to the lower end opening of the first air guide duct 24, the one-way sealing plug 28 is movably fitted with the opening of the first air guide duct 24 through a spring connected to the end hole 25, a sliding through hole 26 is penetrated on the lower side of the rod body 21, the elastic kit 4 is slidably connected to the sliding through hole 26, and second guide slots 27 are symmetrically embedded on the upper and lower sides of the sliding through hole 26, and the second guide slot 27 located on the upper side of the sliding through hole 26 is connected to the first air guide duct 24.

[0036] Preferably, in order to improve the mobility of the rod body 21, a plurality of groups of balls 23 are embedded at the lower end of the first slider 22, and the balls 23 are slidably fitted with the bottom of the first guide slot 11. When in use, when the driving rod 52 rotates and drives the elastic kit 4 to move toward the base 5, the elastic kit 4 drives the rod body 21 to move together, and the first slider 22 slides in the first guide slot 11. At this time, when the first air duct 24 is exhausted, the one-way sealing plug 28 is pushed out of the first air duct 24 by the airflow, and the airflow is discharged. When the edge of the clamped special-shaped LED display is stable, the elastic kit 4 will slide relatively in the sliding through hole 26 and block under the opening of the first air duct 24, so that the one-way sealing plug 28 cannot move away from the first air duct 24, so that the airflow in the first air duct 24 cannot be discharged, and the slide bar 36 cannot move relative to the cover 3, so that the clamping of the special-shaped LED display can be achieved.

[0037] Among them, the elastic kit 4 includes a third slider 41 that is slidably fitted in the sliding through hole 26, and a threaded hole 42 is set through the third slider 41. The threaded hole 42 is movably connected to the driving rod 52 through threaded fitting. The third slider 41 is symmetrically connected with fourth sliders 43 on both sides. The fourth slider 43 is slidably fitted with the second guide slot 27. The fourth slider 43 is located on the side of the lower end opening of the first air guide duct 24 away from the base 5. A spring is connected between the fourth slider 43 and the side of the second guide slot 27 away from the base 5. Preferably, the end of the fourth slider 43 close to the base 5 is inclined. In this way, when the third slider 41 is close to the base 5, even if the one-way sealing plug 28 has not yet completely recovered to fit the opening of the first air duct 24, the inclined surface of the fourth slider 43 facilitates pushing the one-way sealing plug 28, and the sliding cooperation between the fourth slider 43 and the second guide slide groove 27 can prevent the third slider 41 from falling off from the sliding through hole 26, and when the slide bar 36 is completely in contact with the surface of the special-shaped LED display screen, the cooperation between the driving rod 52 and the threaded hole 42 drives the third slider 41 and the fourth slider 43 to continue to slide, so that the fourth slider 43 gradually moves to the bottom of the one-way sealing plug 28, thereby preventing the first air duct 24 from continuing to exhaust, thereby achieving the effect of stabilizing the slide bar 36.

[0038] like Figure 7-10 As shown, the one-way sealing plug 28 includes a thin sheet 2801, and a protrusion 2803 adapted to the opening size of the first air duct 24 is concentrically arranged on the thin sheet 2801 near the opening of the first air duct 24, and a sealing ring 2805 is arranged on the periphery of the protrusion 2803. A groove 2802 is embedded in the edge of one side of the thin sheet 2801 near the first air duct 24, and sliding rods 2804 are symmetrically connected on both sides of the thin sheet 2801 near the surface of the first air duct 24, and the sliding rods 2804 are slidably embedded in both sides of the opening of the first air duct 24.

[0039] In this way, the spring can be connected between the groove 2802 and the end hole 25, so that the thin film 2801 and the protrusion 2803 can be combined to form a one-way ventilation valve. The protrusion 2803 and the sealing ring 2805 can improve the sealing effect, and the sliding rod 2804 can facilitate stable guidance.
