With the above design, it can meet the projection requirements of the digital sand table through the splicing design of two projection screens, and at the same time avoid the load caused by any projection screen to the power equipment during the lifting or rotating process due to its excessive weight If it is too large, it will cause damage to related equipment.

As an improvement of the present utility model, in the fixed bracket, the side connected to the electric shaft is the fixed side, and the other two sides are the connecting side; The end parts of the connecting side parts are attached to each other, and the adhering surfaces and the vertical plane form an acute angle with each other. With the above-mentioned design, the two fixing brackets can be spliced together through the mutual fit design, so that the two fixing brackets can be spliced more smoothly, so that the splicing stability of the projection screen inside it is also improved, and then improved. The shaping effect of the digital sand table on the projection screen.

As an improvement of the present invention, the projections of the physical sand table on the horizontal plane are located inside the projection on the same horizontal plane when the projection screen is in the horizontal direction. By adopting the above-mentioned design, it can prevent the projector unit from interlacing with the physical sand table when projecting onto the projection screen, thereby affecting the display effect and the like.

The above-mentioned lifting sand table that can realize multi-angle display can realize the display of the physical sand table and the digital sand table at the same time. In the specific use process, it can directly project the digital sand table on the physical sand table through the projector unit, so that the two are integrated At the same time, it can also enable the projector group to project the digital sand table onto the projection screen, so that the physical sand table and the digital sand table can be displayed from different perspectives in the same space, so that it can be used for displays with complex functions or perspectives. A more comprehensive introduction to the object; the projection screen and the fixed bracket can be lifted and lowered under the drive of the electric slide table, so that the observer can observe the content of the digital sand table from different angles, and it can also make the display effect dynamic When the digital sand table needs to be projected directly on the physical sand table, the projection screen and the fixed bracket are selected towards the vertical surface driven by the electric rotating shaft, so as to avoid affecting the projection effect of the projector unit on the physical sand table.

The lifting sand table that can realize multi-angle display by adopting the above technical solution can display objects with complex structures or functions at multiple angles in the same space, so that it can be displayed in more detail than the original sand table. Displays to meet the needs of exhibitors and visitors.

Detailed ways

The following specific embodiments are used to further illustrate the present utility model. It should be understood that the following specific embodiments are only used to illustrate the present utility model and are not intended to limit the scope of the present utility model. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to the directions in the drawings, and the words "inner" and "outer ” refer to directions towards or away from the geometric center of a particular part, respectively.

Example 1

As shown in Figures 1 and 2, a lifting sand table capable of multi-angle display includes a sand table support frame 1, a solid sand table table 2 is provided at the bottom of the sand table support frame 1, and a sand table support frame 1 is provided at the top. A plurality of projector units 3 are arranged, and the projection direction of the projector units 3 faces the solid sand table platform 2; two projection screens 4 are arranged in the sand table support frame 1, which are respectively fixed in the fixed brackets 5, and the two fixed brackets They all adopt "凵"-shaped structures, and their openings are opposite to each other. An electric sliding table 6 is respectively arranged on any pair of opposite side end faces of the sand table support frame 1, which corresponds to the fixed bracket 5 one by one; an electric rotating shaft 7 is fixedly arranged on each electric sliding table 6, It extends along the horizontal direction, and the fixed bracket 5 is fixed on the electric rotating shaft 7 .

With the above design, it can meet the projection requirements of the digital sand table through the splicing design of two projection screens, and at the same time avoid the load caused by any projection screen to the power equipment during the lifting or rotating process due to its excessive weight If it is too large, it will cause damage to related equipment.
