Description

Technical Field

[0001] The utility model relates to a movable fixing structure, in particular to a tiltable three-dimensional digital sand table display screen fixing structure. Background Art

[0002] The 3D digital sand table integrates geographic information system (GIS) technology, rich map data resources and cutting-edge 3D visualization interactive display technology. It accurately simulates the complex 3D battlefield environment and displays it on an interactive display plane, providing an accurate, efficient and easy-to-operate support platform for military command decision-making, troop training and reporting presentations.

[0003] Existing 3D digital sandbox equipment typically features a large display surface, requiring it to be tilted and flipped for easier viewing and operation. During this tilt and flip process, due to the heavy weight of the display surface, which may be composed of multiple separate screens, applying force directly from the tilt and flip actuator to the display surface can cause deformation or displacement, affecting the display quality or even damaging the screen. Furthermore, this deformation or displacement can interfere with the sandbox frame when it falls back, preventing the screen from being inserted into the display, potentially damaging the equipment or injuring the operator.

[0022] The preferred technical solution of the present utility model is described in detail below with reference to the accompanying drawings and specific implementation methods.

[0023] like Figure 1 As shown, a tiltable three-dimensional digital sandbox display plane connection structure is characterized in that it includes a connecting bracket 1 and a screen support frame 2 detachably installed on both sides of the connecting bracket 1, the connecting bracket 1 is spliced ​​into a closed ring by multiple horizontal beams and vertical beams, and the sandbox interactive display plane 3 is installed on the connecting bracket.

[0024] like Figure 2 As shown, the connecting bracket 1 is provided with a locking screen horizontal beam 10, a locking screen vertical beam 11 and a connecting bracket 12 in the form of a hoop. The connecting bracket 12 is fixed to the locking screen vertical beam 11 through fasteners after being inserted into the locking screen horizontal beam 10. A limited angle piece 13 is provided at the joint of the locking screen horizontal beam 10 and the locking screen vertical beam 11. The two vertical surfaces of the limited angle piece 13 are respectively fixed to the locking screen horizontal beam 10 and the locking screen vertical beam 11 through fasteners.

[0025] Further, such as Figure 3 As shown, the screen support frame 2 has a first bend 21, a second bend 22, and a third bend 23. The first bend 21 and the third bend 23 are arranged perpendicularly. The first bend 21 and the third bend 23 are provided with waist-shaped through holes 200. The side of the connecting bracket 1 can be provided with internal threads, rivet nuts, etc. The first bend 21 is mounted and fixed to the sand table interactive display plane 3 via fixings, and the third bend 23 is mounted and fixed to the connecting bracket 1 via fasteners. By mounting the sand table interactive display plane 3 on one side of the connecting bracket 1 and the tilt and flip actuator on the other side of the connecting bracket 1, the forces acting on the sand table interactive display plane 3 and the tilt and flip actuator are both applied to the rigid structure. During the tilt and flip process, the forces are balanced, and the screen is not easily deformed or displaced. At the same time, the screen support frame 2, which can be detachably mounted on both sides of the connecting bracket 2, provides the connection structure with better sealing and overall rigidity, further preventing deformation and displacement of the sand table interactive display plane.

[0026] like Figure 3 、 4As shown, an integrally formed reinforcing rib 201 is provided on the first bending portion 21, the second bending portion 22, and the third bending portion 23. The reinforcing rib 201 is usually made of a metal sheet that is punched or welded, and then welded to each bending portion. The reinforcing rib 201 extends along the bending length direction of the first bending portion 21 or the third bending portion 23. One end of the reinforcing rib 201 is connected to the first bending portion 21, and the other end is connected to the third bending portion 23, and is usually connected by welding. By adding reinforcing ribs that fit the bending shape to each bending portion, the overall structural rigidity of the screen support frame 2 is further enhanced, thereby preventing deformation and displacement of the interactive display plane of the sandbox, and preventing interference with the sandbox body frame when falling back, which affects the embedding of the display screen.

[0027] like Figure 3 、 4 As shown, the first bend portion 21 is configured as a plurality of independent first bend edges 210, and one end of the reinforcing rib 201 is connected to the first bend edge 210, typically by welding. By providing multiple independent first bend edges 210, the mounting position can be set according to installation requirements, reducing the overall weight of the screen support frame 2 while ensuring connection strength.

[0028] Further, such as Figure 5 As shown, the second bending portion 22 is configured to include a second bending edge 220 and a third bending edge 221, which can enable the screen support frame 2 to adapt to the shapes of both sides of the sandbox interactive display plane 3 and have better sealing and overall rigidity.

[0029] Further, such as Figure 6 As shown, the connecting bracket 1 is provided with a boss 100 on the front side facing the sand table interactive display plane 3 for connecting to the sand table interactive display plane 3, and a push rod bracket 101 is provided on the vertical beam on the back side of the connecting bracket for installing a push rod for controlling the tilt and flipping of the sand table interactive display plane.

[0030] The present application has been described in detail above with reference to specific embodiments. Those skilled in the art will appreciate that, without departing from the technical content of the present invention, various replacements or improvements may be made to the technical solution and its implementation, all of which fall within the scope of protection of the present invention.
