Description

Technical Field

[0001] This utility model relates to the field of hinge technology, specifically a hinge suitable for the opening structure of LED large screen doors. Background Technology

[0002] In LED large screen performances, since the large screen covers the entire stage, people who need to go on stage can only enter the middle of the stage from the side. This is not only a long journey, but also time-consuming and laborious, and the entrance effect is not good. Therefore, opening a door in the middle of the large screen has become an indispensable part of the application of stage large screen.

[0003] Because the screens are tightly fitted together, existing hinges cannot allow the screens to be opened by pushing, pulling, or rotating like a regular door. Since existing hinges cannot achieve this, some compromise solutions require hinges. One such solution is to directly fix the screen portion (which acts as a door) to a trolley and pull it backward. This is not only unsightly, but also presents significant wiring issues. Utility Model Content

[0004] This invention provides a hinge suitable for the door opening structure of LED large screens, solving the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A hinge suitable for the opening structure of an LED large screen includes a suspension plate, with extension plates at both ends of the suspension plate. A first linear slide groove and a second linear slide groove are provided on the side of the extension plate near the suspension plate. The first linear slide groove and the second linear slide groove are collinear. An arc-shaped slide groove communicating with the second linear slide groove is provided at the end of the second linear slide groove away from the first linear slide groove. Two limiting pins are provided at both ends of the suspension plate, which respectively cooperate with the first linear slide groove and the second linear slide groove. The distance between the two limiting pins is longer than the length of the second linear slide groove.

[0007] As a preferred embodiment of this utility model, the limiting pin is threadedly connected to the suspension plate.

[0008] As a preferred technical solution of this utility model, the end of the protruding plate away from the second linear slide groove is provided with a mounting seat that is perpendicular to the protruding plate.

[0009] The present invention has the following advantages:

[0010] This utility model applies to a hinge suitable for the opening structure of an LED screen. By cooperating with the limiting pin shaft with the first linear slide groove, the second linear slide groove and the arc-shaped slide groove respectively, the LED screen can move horizontally first and then rotate, avoiding the problem of interference between the LED screens on both sides. This allows the LED screen to be pushed, pulled and rotated like a normal door, but without damaging the screen or requiring special wiring harnesses. Attached Figure Description

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] In one embodiment, see Figures 1-4A hinge suitable for the opening structure of an LED large screen includes a suspension plate 3. Extending plates 1 are provided at both ends of the suspension plate 3. A first linear groove 5 and a second linear groove 6 are provided on the side of the extending plate 1 closest to the suspension plate 3. The first linear groove 5 and the second linear groove 6 are collinear. An arc-shaped groove 7 communicating with the second linear groove 6 is provided at the end of the second linear groove 6 furthest from the first linear groove 5. Two limiting pins 4 are provided at both ends of the suspension plate 3, respectively cooperating with the first linear groove 5 and the second linear groove 6. The distance between the two limiting pins 4 is longer than the length of the second linear groove 6. The limiting pins 4 are threadedly connected to the suspension plate 3. A mounting base 2, perpendicular to the extending plate 1, is provided at the end of the extending plate 1 furthest from the second linear groove 6.

[0019] During installation, firstly, the protruding plate 1 is fixed to the base using the mounting base 2, with the upper and lower protruding plates 1 set flush. Then, the suspension plate 3 is removed. The suspension plate 3 has a U-shaped structure. The protruding ends of the suspension plate 3 are placed outside the upper and lower protruding plates 1. The threaded mounting holes at both ends of the suspension plate 3 are aligned with the first linear slide groove 5 and the second linear slide groove 6. First, the two upper limit pins 4 are screwed into the two upper threaded mounting holes. Then, the two lower limit pins 4 are screwed into the two lower threaded mounting holes. At this point, the suspension plate 3 and the protruding plate 1 are assembled. The LED screen that needs to be fixed is then fixed to the upper and lower mounting holes of the suspension plate 3.

[0020] During use, pushing the suspension plate 3 backward moves the rear limiting pin 4 to the rear of the first straight slide 5, and the front limiting pin 4 moves to the rear of the second straight slide 6. At this time, the suspension plate 3 moves to the rear, and the LED screen is positioned at the rear and parallel. The LED screen is now flush and can operate normally. When it is necessary to unfold the LED screens on both sides, pulling the LED screen forward moves the two limiting pins 4 forward along the first straight slide 5 and the second straight slide 6 respectively. At this time, the LED screen remains parallel and moves horizontally. After the front limiting pin 4 moves to the front end of the first straight slide 5, the limiting pin 4 can slide along the arc-shaped slide 7, thereby causing the LED screen to rotate.

[0021] This utility model applies to a hinge suitable for the opening structure of an LED screen. By using the limiting pin 4 to cooperate with the first linear slide 5, the second linear slide 6 and the arc-shaped slide 7 respectively, the LED screen can move horizontally first and then rotate, avoiding the problem of interference between the LED screens on both sides. This allows the LED screen to be pushed, pulled and rotated like a normal door, but without damaging the screen or requiring special wiring harnesses.

[0022] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
