Description

Technical Field

[0001] The present invention relates to the technical field of LED screens, and in particular to an LED splicing box structure that can adapt to any curvature. Background Art

[0002] At present, LED (Light Emitting Diode, LED) display screen is a flat panel display composed of small LED module panels. It is used to display various information such as text, images, videos, and recording signals. The high brightness, wide viewing angle and good color reproduction ability of LED display screens are also better than LCD screens. LED screen refreshers are generally used in airports, shopping malls, hotels, high-speed railways, subways, cinemas, exhibitions, office buildings, etc. The target customers have strong consumption power and have huge advertising value.

[0003] Due to different environmental requirements, LED displays will form different curved surfaces according to different requirements. Existing LED displays first install and fix the entire LED splicing frame, and then install the LED module panel to the corresponding LED splicing frame.

[0004] This results in the LED module panels being fixed and non-adjustable, and unable to adapt to any curvature. When changing to a different curved surface, the entire panel needs to be disassembled, and the LED splicing frame also needs to be disassembled and reinstalled into the required shape. This results in a large overall engineering workload, great trouble, and higher cost.

[0060] Reference Figure 6-9 , a plurality of second limiting grooves 552 are provided on the side wall of the positioning rod 551, and the second limiting lock tongue 554 is slidably connected in the corresponding second limiting groove 552, and a second limiting spring 553 is fixedly connected in the second limiting groove 552 and is used to drive the second limiting lock tongue 554 to automatically pop out, and a push plate 646 that can move back and forth and is used to squeeze and shrink the second limiting lock tongue 554 is provided in the second lock groove 641, and a transmission groove 642 is provided in the first rod 61, and a transmission block 647 that is slidably connected is provided at one end of the transmission groove 642, and a transmission groove 642 is provided on one side thereof, which is connected to the second lock groove 641.

[0061] Reference Figure 6-9The second rod 62 is provided with a recovery groove 621 inside, and a recovery rod 63 is provided in the recovery groove 621 for sliding connection and movement up and down. The extended end of the recovery rod 63 passes through the upper inner wall of the positioning groove 64, and the extended end of the recovery rod 63 is provided with a protrusion 631 fixedly connected and used to prevent the recovery rod 63 from separating from the positioning groove 64.

Example 3

[0063] The same points as Example 2 are not described here. The differences from Example 2 are as follows:

[0065] Working principle:

[0066] When in use, first install and fix the LED splicing frame 2, connect and fix the adjustment rod 31 on each group of mounting plates 3 with the corresponding LED splicing frame 2, and then distribute and fix the LED module panels 1 on the corresponding mounting plates 3. Before installation, connect and fix the end of the corresponding second rod 62 with the LED splicing frame 2. At this time, the preliminary installation is completed;

[0067] According to the set shape, the length of the adjustment rod 31 at different positions is controlled, and the corresponding LED module panel 1 reaches the set position, so that the LED module panel 1 can form a set curved surface;

[0068] When the overall curved surface shape needs to be changed, it is only necessary to replace some curved surface parts with matching LED module panels 1 with curved surfaces. After the replacement is completed, it is only necessary to control the length of the adjusting rod 31 so that the multiple LED module panels 1 reach the set position according to the set degree and tilt to the set angle, thereby completing the change of different curved surfaces and being able to adapt to different curvature curved surfaces; and the adjusting rod 31 and the mounting plate 3 are used to replace the original fixed installation method between the LED module panel 1 and the LED splicing frame 2. This flexible installation method can adjust the specific position between the LED module panel 1 and the LED splicing frame 2 at different positions according to different situations, and can also adjust the inclination angle of the LED module panel 1, so that the LED module panel 1 can be controlled to present different shapes according to different needs, making the overall structure more flexible, better controlled and adjusted, and also reducing the cost of the LED splicing frame 2;

[0069] After the LED module panel 1 has been used for a period of time, when the outer surface of one or some of the LED module panels 1 is covered with too much dust, resulting in unclear images, it is only necessary to control the corresponding adjustment rods 31 to contract synchronously to drive the LED module panel 1 to move toward the LED splicing frame 2. As the LED module panel 1 moves, the multiple extrusion rods 6 will be driven to move toward the positioning rod 551, and the extrusion plate 52 will be driven by the first transmission shaft 54 ​​to squeeze in the high-pressure tank 50. At this time, since the valve plate 46 will seal the outlet of the connecting hose 51, the extrusion plate 52 can form a high-pressure environment in the high-pressure tank 50. When the positioning groove 64 on the first rod 61 is fully inserted into the positioning rod 551, the high-pressure value in the high-pressure tank 50 is reached, and the pressurization is completed.

[0070] After the pressurization is completed, the LED module panel 1 will continue to move. At this time, the second limit lock tongue 554 will automatically pop out due to the elasticity of the spring. The second limit lock tongue 554 is locked and fixed with the second lock tongue. The position of the second transmission shaft 643 is locked by the positioning rod 551, ensuring the stability of the air pressure in the high-pressure tank 50. The end of the positioning rod 551 can push the recovery rod 63 upward, driving the recovery rod 63 to move toward the recovery groove 621. The movement of the recovery rod 63 can squeeze the third limit lock tongue 622 toward the third limit groove. Through the transmission of the linkage part 623, the first limit lock rod 625 can be driven to automatically retract into the first limit groove. At this time, the lock between the first rod 61 and the second rod 62 is automatically released. The continued movement of the LED module panel 1 will push the second rod 62 in The first slide groove 611 slides, so that the extrusion rod 6 automatically turns into a telescopic rod after pushing the extrusion plate 52 to the set position. At this time, as the LED module panel 1 continues to move, the synchronization plate 7 and the side wall of the LED splicing frame 2 are released, pushing the synchronization plate 7 toward the side wall of the LED module panel 1. When the rack on the synchronization plate 7 moves to the synchronization gear 73, the synchronization gear 73 can be driven to rotate through meshing transmission, and the hinge shaft 84 can be driven to rotate through the transmission of the synchronization chain 83 and the transmission chain 76, thereby driving the first hinge plate 81 and the cleaning plate to rotate 180 degrees around the hinge shaft 84, so that the cleaning box 4 is vertically perpendicular to one end of the LED module panel 1. At this time, the cleaning slot 42 is located on the outer surface of the LED module panel 1, and the adjustment rod 31 stops retracting;

[0071] Since the length of the transmission member 461 is fixed, when the LED module panel 1 completes its rotation, the length of the transmission member 461 can just pull the valve plate 46 to separate the guide groove 44 and open the outlet end of the connecting hose 51. At this time, the high-pressure airflow in the high-pressure groove 50 enters the regulating groove 45 through the connecting hose 51, and then enters the regulating pipe 43, enters the cleaning pipe 41 through the regulating pipe 43, and then enters the corresponding cleaning branch pipe 414 in sequence through the connecting pipe 411. Since the aperture of the cleaning hole 413 is small, the air pressure accumulates, and the air pressure can automatically push the regulating pipe 43 to extend. Moreover, due to the design of the position of the cleaning hole 413, the cleaning hole 413 can be flushed by the reaction of the airflow. The force drives the cleaning branch pipe 414 to rotate, so that the multiple cleaning branch pipes 414 rotate in one direction on the outer surface of the LED module panel 1. The high-pressure airflow in the cleaning hole 413 can effectively clean the outer surface of the LED module panel 1. At the same time, the cleaning brush filaments 412 can wipe the outer surface due to the rotation of the cleaning branch pipe 414, thereby improving the overall cleaning efficiency and realizing automatic cleaning of the LED module panel 1. When the cleaning branch pipe 414 moves from one end to the other end, the cleaning is completed and the air pressure is released. At this time, the elasticity of the fourth return spring 47 can automatically cause the cleaning branch pipe 414 to automatically move back to the cleaning slot 42, thereby realizing automatic recovery of the cleaning branch pipe 414 after cleaning.

[0072] After cleaning is completed, the start-up adjustment rod 31 automatically extends, and as the LED module panel 1 moves, the synchronization plate 7 automatically returns to its initial position due to the elasticity of the third reset spring, thereby driving the hinge shaft 84 to rotate through the transmission of the synchronization rack 72, the synchronization chain 83, and the transmission chain 76, so that the cleaning box 4 automatically rotates and returns to its initial position; thus, the automatic reset of the cleaning box 4 is achieved;

[0073] As the LED module panel 1 continues to move outward, the second rod 62 can be driven to move outward inside the first rod 61. When the connecting piece 613 is tightened, the connecting piece 613 at the end of the second rod 62 can pull the transmission block 647 to move. The second transmission shaft 643 is driven to drive the push plate 646 to move outward, so that the push plate 646 automatically squeezes the second limiting lock tongue 554 into the second limiting groove 552. At this time, the lock between the first rod 61 and the positioning rod 551 is released. At the same time, the first limiting lock rod 625 moves to the first limiting groove and automatically pops out to engage with the first limiting groove.

[0074] As the LED module panel 1 continues to move outward, the first rod 61 can be driven to separate from the positioning rod 551. At the same time, the squeezing rod 6 can automatically squeeze the plate 52 to automatically restore its initial position. As the squeezing plate 52 returns to its initial position, air flows into the high-pressure tank 50 through the air inlet 53 to replenish gas for the next squeezing. The one-way valve 531 can prevent gas from being discharged. Then, the length of the hole adjustment rod 31 is restored to its initial position, so that the LED module panel 1 can be restored to its initial position.

[0075] The cleaning box is automatically rotated as a whole, and the cleaning pipe 41 and the cleaning branch pipe 414 automatically move back and forth to automatically clean the outer surface of the LED module panel 1; the cleaning box 4 automatically rotates and recycles after cleaning, and realizes automatic replenishment of high-pressure airflow;

[0076] Since a large curved screen is composed of a large number of LED module panels 1, if each LED module panel 1 uses one or several driving mechanisms to clean the surface of the LED module panel 1, this will bring about a large cost investment, resulting in an overall cost that is too high, and the control system is more complicated; and the design of the synchronization plate 7, synchronization gear 73, synchronization chain 83, extrusion rod 6, extrusion plate 52, high-pressure box 5 and connecting hose 51 can, through structural coordination, utilize the kinetic energy generated by the back and forth movement of the LED module panel 1 to achieve automatic pressurization of the high-pressure box 5, rotation of the cleaning box, automatic release of pressure after rotation, and automatic cleaning of the surface of the LED module panel 1 by the cleaning branch 414; it not only achieves the cleaning of the surface of the LED module panel 1, but also reduces the overall cost, and also replaces manual cleaning of the surface of the LED module panel 1.
