However, the supporting structure of traditional stages is usually a truss or column, which is generally connected by buckles or bolts. This connection method is relatively cumbersome, and the stage is also prone to shifting on top, resulting in poor stability. In addition, due to the different sizes of stages, the traditional supporting structure is not conducive to the rapid expansion or reduction of the stage area, and the usage effect is not ideal.

[0027] The present invention will now be described in further detail with reference to the accompanying drawings. The drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.
[0028] Please refer to Figure 1-7 A stage structure includes four vertically arranged support pipes 1 and a stage body 5 at the top. Each support pipe 1 is provided with two layers of fixing plates 2. Of course, the number of fixing plates 2 can also be multiple layers, the specific number of layers being determined according to actual needs. An upper horizontal bar 4 is provided between every two fixing plates 2 in the upper layer. A trapezoidal boss 44 is integrally provided on the surface of the upper horizontal bar 4. Multiple Z-shaped limiting plates 41 are provided on both sides of the surface of the trapezoidal boss 44. The limiting plates 41 are fixed to the trapezoidal boss by welding. The stage body 5 is surrounded by the limiting plates 41. The inner surface of the trapezoidal boss 44 is in contact with the upper crossbar 4. Since the trapezoidal boss 44 is integrally set with the upper crossbar 4, the overall strength of the upper crossbar 4 can be greatly enhanced, thereby increasing the support for the upper stage body 5. In addition, since multiple limiting plates 41 are set on both sides of the trapezoidal boss 44, a limiting groove is formed between two opposing limiting plates 41. When assembling the stage body 5, the four sides of the stage body 5 are in contact with the surface of the trapezoidal boss 44 in the limiting groove. After assembly, due to the setting of the limiting plates 41, the stage body can be prevented from detaching from the support, thereby improving the overall stability.
[0029] In this embodiment, a lower crossbar 3 is provided between every two fixed plates 2 on the lower layer. Both ends of the upper crossbar 4 and the lower crossbar 3 are provided with slots 42. The upper crossbar 4 and the lower crossbar 3 are inserted into the fixed plate 2 at the slots 42. In addition, the surface of the fixed plate 2 is provided with multiple limiting holes. A vertically penetrating pin 43 is provided in the slot 42. The pin 43 penetrates the fixed plate 2 at the limiting holes. That is to say, the pin 43 vertically passes through the upper and lower crossbars and the fixed plate 2 at the connection, preventing the upper and lower crossbars from detaching from the fixed plate 2, so as to achieve the purpose of limiting and thus providing stable support for the stage panel.
[0030] To prevent the pin 43 from coming loose, the width of the pin 43 gradually increases from bottom to top. After passing through, the wider top ensures that the overall connection remains stable.
[0031] In addition, the height of the upper crossbar 4 is greater than its width, making the whole structure more robust and improving its overall load-bearing capacity.
[0032] In this embodiment, the stage body 5 includes a frame 52 and a stage panel 51 disposed on the frame 52. The inner wall of the frame 52 is provided with an assembly step 54, and the stage panel 51 is fixedly connected to the frame 52 at the assembly step 54.
[0033] The stage panel 51 is made of plywood used in construction, and the plywood is fixed to the assembly steps 54 with nails.
[0034] Of course, the stage panel 51 can also be made of other materials such as thicker stainless steel plates or wooden floors, as long as it can provide a stable platform for people to move around and stand.
[0035] To ensure the strength of the stage body 5, the interior of the frame 52 is also provided with crisscrossing reinforcing rods 53, the ends of which are fixedly connected to the frame 52 by welding.
[0036] Please refer to this again. Figure 8-9 The frame 52 is also provided with through holes 55. Each pair of adjacent stage bodies 5 are fixedly connected at the through holes 55 by bolts to expand the stage area.
[0037] Of course, the corners of the frame 52 and the stage panel 51 can be chamfered as needed. Whether or not chamfering is needed depends on the on-site processing dimensions.
[0038] In this embodiment, the four upper horizontal bars 4 form a 1*2m frame for placing a 1*2m stage body; when the four upper horizontal bars 4 form a 2*2m frame, it is used to place a 2*2m stage body, and two 1*2m stage bodies can also be placed there.
[0039] Please refer to Figure 10 Based on the above embodiments, upper crossbars 4 and lower crossbars 3 can be installed in all four directions of the fixed plate 2, and the stage area can be expanded in this way, which is conducive to stage expansion.
[0040] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the protection scope of this invention.
