Description

Technical Field

[0001] The utility model relates to the technical field of educational demonstration, in particular to a teaching three-dimensional scene demonstration device. Background Art

[0002] Teaching 3D scene demonstration means that in order to help students better understand the learning content, teachers usually place real objects or models on the podium during classroom teaching, so that students can better observe and understand the learning content, deepen their understanding of the text, and improve the quality of students' learning.

[0003] Currently, when teachers demonstrate teaching objects, they usually place the objects on the podium for demonstration. However, in order to facilitate viewing by students in the middle and back rows, the teaching objects need to be lifted to a certain height during the explanation so as to fully demonstrate them. However, the lifting demonstration method is tiring, and the demonstration method of lifting the teaching objects by objects has poor stability and is inconvenient to use.

[0004] Therefore, we propose a teaching three-dimensional scene teaching device to solve the above-mentioned problems. Summary of the invention

[0005] The purpose of the utility model is to provide a teaching three-dimensional scene teaching device to solve the problem that the teacher usually places the teaching object on the podium for display when displaying the teaching object, but in order to facilitate the students in the middle and back rows to watch, it is necessary to lift the teaching object to a certain height during the explanation so as to fully display it, while the lifting display method is tiring, and the display method of lifting the teaching object by an object has poor stability and is inconvenient to use.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a teaching stereoscopic scene teaching device, comprising a fixed base and a support table fixedly installed on one side of the upper end of the fixed base, a storage groove is opened in the middle of one end of the outer wall of the support table, a long block is fixedly installed on the other side of the upper end of the fixed base, a secondary storage groove is opened at the lower end of one end of the outer wall of the long block, and a cover assembly is magnetically connected to the upper end of the long block;

[0007] A lifting mechanism is fixedly installed in the middle of the upper end of the inner cavity of the long block, a load-bearing mechanism is movably installed on the upper end of the lifting mechanism, positioning mechanisms are threadedly connected on both sides of the upper end of the load-bearing mechanism, and circular magnetic grooves are respectively opened at the four corners of the upper end of the long block.

[0008] Preferably, the lifting mechanism comprises an electric telescopic column and a dome block fixedly mounted on the upper end of the electric telescopic column, and an expansion ring is fixedly mounted on the middle part of the outer wall of the dome block.

[0009] Preferably, the load-bearing mechanism comprises an embedded long block and a hollow round block embedded in the middle of the lower end of the embedded long block, and a limiting annular groove is provided in the middle of the inner wall of the hollow round block.

[0010] Preferably, vertical plates are fixedly mounted on both sides of the upper end of the embedded long block, and a threaded groove is provided in the middle of one end of the vertical plate.

[0011] Preferably, the positioning mechanism comprises a long threaded rod and a bearing fixedly mounted on one end of the long threaded rod.

[0012] Preferably, the sealing cover assembly includes a long cover plate and magnetic plug posts fixedly installed at the four corners of the lower end of the long cover plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. When the teacher needs to use the teaching object for demonstration, the long cover plate can be pulled out to disengage the magnetic plugs fixed at the four corners of the lower end of the long cover plate from the inner cavity of the circular magnetic groove, and the embedded long block can be driven out of the inner cavity of the long block by starting the electric telescopic column, and the object to be displayed can be placed on the upper end of the embedded long block, and the pressing plate can be driven to limit and fix the lower ends of the object by rotating the threaded long rod. When displaying the object, the operator can directly rotate the embedded long block so that the embedded long block drives the object to rotate at the upper end of the dome block, and at the same time, it is limited and fixed by the expansion ring around the outer wall of the dome block. By rotating the embedded long block, the object can be displayed at multiple angles, and the teacher does not need to manually lift the object, which is convenient for the teacher to better explain and introduce the object.

[0015] 2. When fixing the object embedded in the upper end of the long block, the teacher can rotate the threaded long rods on both sides of the upper end of the embedded long block. The threaded long rods are threadedly connected to the inner cavity of the threaded groove opened in the middle of the vertical plate. When the thread of the threaded long rod rotates, it will drive the pressure plate forward, thereby allowing the pressure plate to limit and fix the two sides of the lower end of the object.
