Description

Technical Field

[0001] This utility model belongs to the field of combined platform technology, specifically relating to a positioning frame structure for a movable support. Background Technology

[0002] Most common modular platform support frames use scissor-type horizontal bracing that can be folded up. The advantages of this type of support are its simple structure, space-saving design after disassembly and folding, and ease of storage and transportation. However, it also has the following problems: with only four points directly supporting the platform, it is prone to warping and deformation due to concentrated stress on larger or heavier platforms; due to its foldable nature, there is a lack of constraint on the extent of the support's extension during use, making it difficult to ensure the squareness of the support surface and the accuracy of the support point positions. Furthermore, the support is susceptible to external interference, causing the columns to shift and altering the stress state, thus affecting the safety and stability of the support. Utility Model Content

[0003] To address the positioning and stability issues of movable support frames for modular platforms, this invention provides a positioning frame structure for movable supports. This movable support is used in spatial three-dimensional demonstration stages or modular platforms, achieving reliable integration with the movable support while significantly enhancing the stability of the support structure.

[0004] To achieve the above objectives, the present invention adopts the following specific technical solution: A positioning frame structure for a movable support frame, which supports a three-dimensional simulation stage, wherein the movable support frame, when unfolded, has a column at each of its four corners; the positioning frame structure includes a square frame and four positioning plates. The square frame is a square frame structure, and its external dimensions are consistent with the planar dimensions of the unfolded movable support; a positioning plate is fixedly connected to each of the four corners of the bottom surface of the square frame; The positioning plate is set vertically, with the intersection of the diagonal of the square frame and the center of the corresponding column as the center, and is set perpendicular to the diagonal. The positioning plates correspond one-to-one with the columns and are inserted into each other.

[0005] Furthermore, the positioning plate is a rectangular flat plate structure.

[0006] Furthermore, the height of the positioning insert is 2 / 3 of the width of the positioning insert.

[0007] Furthermore, the column is a tubular column.

[0008] Furthermore, the width of the positioning plate is smaller than the inner diameter of the column.

[0009] Furthermore, the width of the positioning plate is 2mm less than the inner diameter of the column.

[0010] Furthermore, the bottom two corners of the positioning plate are chamfered at 45 degrees.

[0011] Furthermore, the height of the chamfer is 1 / 4 of the height of the positioning insert.

[0012] Compared with the prior art, the technical solution of this utility model has the following beneficial effects: 1. This utility model adopts a square frame to change the way the movable support exerts force on the upper platform, that is, it changes from the four-point support in the existing technology to the square frame support, making its stress state more reasonable, and at the same time avoiding the warping and deformation of the platform caused by uneven force.

[0013] 2. By setting a positioning plate on the square frame, this utility model not only achieves a reliable combination with the movable support below, but also solves the problem of limiting the positioning of the movable support after it is unfolded, locking the column of the movable support, and at the same time greatly enhancing the stability of the support structure.

[0014] 3. In this utility model, the lower end of the positioning plate is chamfered at 45 degrees. The chamfer makes it easier to insert the positioning plate into the movable bracket when assembling the movable bracket.

[0015] 4. The positioning frame structure and movable bracket of this utility model are detachably combined, which not only makes installation and disassembly simple, but also facilitates transportation and storage after disassembly. Attached Figure Description

[0020] For the movable support 1 with scissor-type cross bracing, the positioning frame structure 2 of this utility model needs to solve the following problems: First, change its stress state from point support to frame support; second, strengthen the stability of the support, especially solve the problem of positioning its extension degree.

[0021] like Figure 1 , Figure 2 and Figure 3 As shown, this embodiment of the utility model provides a positioning frame structure 2 for a movable support 1. The movable support 1 is used to support a three-dimensional simulation stage. When unfolded, the movable support 1 has a column at each of its four corners. The movable support 1 is a scissor-type horizontal brace that can be joined together. The positioning frame structure 2 includes a square frame 21 and four positioning plates 22.

[0022] The square frame 21 serves as a transition structure for the stress state at the upper end of the movable support 1. The square frame 21 is a square frame structure, and its external dimensions are consistent with the planar dimensions of the unfolded movable support 1. Using consistent dimensions facilitates reasonable load transfer.

[0023] The positioning plates 22 are used to solve the positioning problem after the movable support 1 is unfolded, and at the same time, to achieve a reliable combination between the square frame 21 and the movable support 1, and to increase the stability of the support. A positioning plate 22 is fixedly connected to each of the four corners of the bottom surface of the square frame 21. The positioning plates 22 correspond one-to-one with the columns and are inserted into each other. The positioning plates 22 are set vertically, specifically centered on the intersection of the diagonal of the square frame 21 and the center of the corresponding column, and are set perpendicular to this diagonal. That is, the surface of the positioning plate 22 is perpendicular to the diagonal of the square frame 21 it is located on. The positioning plate 22 is a vertical rectangular flat plate structure, and the height of the positioning plate 22 is 2 / 3 of its width. When the column is a tubular column, the width of the positioning plate 22 is less than the inner diameter of the column, for example, the width of the positioning plate 22 is 2mm less than the inner diameter of the column. The bottom two corners of the positioning plate 22 are chamfered at 45 degrees, and the height of the chamfer is 1 / 4 of the height of the positioning plate 22. The chamfered structure facilitates the insertion of the positioning plate 22 into the column.

[0024] The positioning frame structure 2 of this utility model consists only of a square frame 21 and a positioning insert 22, making its structure relatively simple. During manufacturing, the square frame 21 can be fabricated first, and then the positioning insert 22 can be welded onto it. The square frame 21 is a square frame structure with an outer side length the same as the support dimensions, both being 1600mm, and is made of 60×40×2mm steel pipe. The positioning insert 22 is a vertical flat plate structure, which can be made of 3mm thick steel plate. After processing, it is welded to the four corners of the bottom surface of the square frame 21. See [reference needed] for details. Figure 2 and Figure 3 After production, it needs to be inspected and its dimensions verified.

[0025] When in use, the positioning frame structure 2 needs to be used in conjunction with the movable support 1. No tools are required for assembly. Simply place the positioning frame structure 2 of this utility model on the unfolded movable support 1 and insert the four positioning plates 22 into the tubes at the top of the four corner columns of the support to complete the assembly. After the assembly is completed, a modular platform or tabletop 3 can be placed on top of it.

[0026] The movable support 1 of the positioning frame structure 2 of this utility model is used to support the three-dimensional simulation platform for space-ground coordinated orbit control. This three-dimensional simulation platform is as follows: Figure 4 As shown, it includes a movable support 1 at the bottom, a positioning frame structure 2 inserted into the movable support 1, a platform 3 supported on the positioning frame structure 2, and a sector plate 4 rotatably mounted on the platform 3.

[0027] Obviously, those skilled in the art can make various modifications and variations to the embodiments of this utility model without departing from the spirit and scope of this utility model. Therefore, if these modifications and variations of this utility model fall within the scope of the claims of this utility model and their equivalents, this utility model also intends to include these modifications and variations.

[0028] In summary, the above are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the scope of protection of this utility model.
