Technical Field
[0001] The utility model relates to the technical field of display screen hinge structures, in particular to an LED display screen hinge structure. Background Technique
[0002] The LED screen is a new type of imaging electronic device made by arranging light-emitting diodes in sequence. Due to its characteristics such as high brightness, wide viewing angle, and long service life, it is widely used in products such as outdoor advertising screens. When the LED screen is used in a folded manner, a hinge structure is required to fold two display screens to meet the usage requirements.
[0003] When the existing LED display screen hinge structure is in use, when the hinge is folded, there is a lack of a limit and buffer structure between the hinge plates, so that the hinge plates cannot be effectively buffered and limited when folded and closed, and the hinge structure is prone to impact and wear when closed. Content of the Utility Model
[0004] The technical problem to be solved by the utility model is to overcome the existing defects and provide an LED display screen hinge structure. By setting a limit plate, a limit cylinder, a ball groove, a limit convex ball, a glue groove, a limit rubber sleeve, a column hole, and a limit rubber column, when the hinge plates are folded and closed, the limit rubber sleeve is inserted into the limit rubber column, so that the hinge plates are buffered and limited when folded, and the impact and wear of the hinge plates when closed are avoided, and the problems in the background technique can be effectively solved.
[0005] To achieve the above object, the utility model provides the following technical scheme: an LED display screen hinge structure, including two hinge plates, a rotating sleeve is arranged on the opposite side edges of the hinge plates, a sealing cover is arranged at the upper end of the rotating sleeve, a limit rubber sleeve is arranged on one side surface of the hinge plate, a column hole is arranged in the center of the limit rubber sleeve, a limit rubber column is arranged on the other hinge plate, a limit plate is arranged on the other side surface of the hinge plate, a limit cylinder is arranged between the limit plates, a glue groove is arranged at one end of the limit cylinder, a ball groove is arranged at the other end of the limit cylinder, and a limit convex ball is arranged at a position of the other limit cylinder close to the ball groove.
[0006] Furthermore, a clamping ring groove is arranged at the connection position of the limit rubber sleeve and the hinge plate, and a screw hole is arranged on the hinge plate.
[0007] Furthermore, the limit rubber sleeve is connected to the hinge plate through the clamping ring groove, and the limit rubber sleeve is connected to the limit rubber column through the column hole.
[0008] Furthermore, the limit plate and the hinge plate are of an integral structure, and the limit cylinder is glued to the limit plate.
[0009] Furthermore, the sealing cover is fixedly connected to the rotating sleeve, and there are two rotating sleeves on a single hinge plate.
[0010] The utility model provides a limiting plate, a limiting cylinder, a ball groove, a limiting convex ball, a rubber groove, a limiting rubber sleeve, a column hole and a limiting rubber column, so that when the hinge plate is folded and closed, the limiting rubber sleeve is plugged into the limiting rubber column, so that the hinge plate is buffered and limited when folded, thereby avoiding impact and wear of the hinge plate when closing.

[0015] See also Figure 1-3 The hinge structure of the LED display includes two hinge plates 1. A rotating sleeve 4 is provided on the opposite sides of the hinge plate 1. A sealing cover 3 is provided on the upper end of the rotating sleeve 4. A limiting rubber sleeve 6 is provided on one side of the hinge plate 1. A column hole 12 is provided in the center of the limiting rubber sleeve 6. A limiting rubber column 7 is provided on the hinge plate 1 on the other side. A limiting plate 5 is provided on the other side of the hinge plate 1. A limiting cylinder 8 is provided between the limiting plates 5. A rubber groove 9 is provided at one end of the limiting cylinder 8, and a ball groove 11 is provided at the other end of the limiting cylinder 8. A limiting convex ball 10 is provided on the other limiting cylinder 8 near the ball groove 11.
[0016] like Figure 1-3 As shown, when the hinge plate 1 is folded and closed, the limiting rubber column 7 can be inserted into the inner side of the sleeve 6, so that the two hinge plates 1 maintain a distance between each other after closing and avoid wear of the hinge plates 1. When the hinge plates 1 are in the open state, the limiting cylinders 8 between the limiting plates 5 can limit and block the limiting plates 5.
[0017] A fixing ring groove 13 is provided at the connection position between the limiting rubber sleeve 6 and the hinge plate 1 , and a screw hole 2 is provided on the hinge plate 1 .
[0018] The limiting rubber sleeve 6 is connected to the hinge plate 1 through the fixing ring groove 13 , and the limiting rubber sleeve 6 is connected to the limiting rubber column 7 through the column hole 12 .
[0019] The limiting plate 5 and the hinge plate 1 are an integrated structure, and the limiting cylinder 8 is glued to the limiting plate 5 .
[0020] The sealing cover 3 is fixedly connected to the rotating sleeve 4, and there are two rotating sleeves 4 on a single hinge plate 1.
[0021] As Figure 1 shown, after the sealing cover 3 is opened, lubricating oil can be added to the rotating shaft inside the rotating sleeve 4 to ensure the stable rotation of the hinge plate 1 and reduce noise.
[0022] During use, the hinge plate 1 is fixedly connected to the display screen housing. When the display screen rotates and folds, the limiting rubber posts 7 between the hinge plates 1 are inserted into the hole 12 of the limiting rubber sleeve 6, so that the hinge plates 1 are limited and fixed to each other, avoiding impact and wear of the hinge plates 1. When the hinge plate 1 is opened, the limiting cylinder 8 between the limiting plates 5 can limit the opening to prevent the hinge plate 1 from opening at too large an angle and ensure the opening effect of the display screen.
