Detailed Implementation

[0020] like Figures 1 to 5 As shown, a movable structure railing stair accessory includes a first connecting component 10 and a second connecting component 20. The first connecting component 10 and the second connecting component 20 are movably hinged together. In use, the first connecting component 10 and the second connecting component 20 can adjust their relative angles by rotating the hinged structure according to the actual needs of the staircase or railing installation site to adapt to connection requirements in different directions.

[0021] In practical implementation, the first connecting assembly 10 includes a sheet metal stretching arc cover 11, a first sheet metal stamping cover 12, and a first connecting pipe 13. The first sheet metal stamping cover 12 is disposed at the bottom of the sheet metal stretching arc cover 11, and the first connecting pipe 13 is disposed on the lower surface of the first sheet metal stamping cover 12. The upper edge of the first connecting pipe 13 is provided with an annular first pipe connecting ring 131. The first pipe connecting ring 131 is in contact with the edge of the first sheet metal stamping cover 12. The edge of the first sheet metal stamping cover 12 is fixed to the bottom edge of the sheet metal stretching arc cover 11 by welding, and the first pipe connecting ring 131 is fixed to the edge of the first sheet metal stamping cover 12 by welding. Thus, the sheet metal stretching arc cover 11, the first sheet metal stamping cover 12, and the first connecting pipe 13 are sequentially welded and fixed together to form a robust, integrated first connecting assembly 10 with low manufacturing cost, suitable for mass production and engineering installation.

[0022] In practice, the plate stretching arc cover 11, the first plate stamping cover 12, and the first connecting pipe 13 are all integrally stamped structures, formed as a whole through mold processing technology, which further improves the structural strength, assembly accuracy and production efficiency of the components, while reducing processing costs.

[0023] In practical implementation, the second connecting assembly 20 includes a movable connecting arc plate 21, a second plate stamping cover 22, and a second connecting pipe 23. The second plate stamping cover 22 is disposed on the top of the movable connecting arc plate 21, and the second connecting pipe 23 is disposed on the upper surface of the second plate stamping cover 22. The lower edge of the second connecting pipe 23 is provided with an annular second pipe connecting ring 231. The second pipe connecting ring 231 is in contact with the edge of the second plate stamping cover 22. The edge of the second plate stamping cover 22 is fixed to the top edge of the movable connecting arc plate 21 by welding, and the second pipe connecting ring 231 is fixed to the edge of the second plate stamping cover 22 by welding. Thus, the movable connecting arc plate 21, the second plate stamping cover 22, and the second connecting pipe 23 are sequentially welded and fixed together, thereby forming a structurally stable and integrally robust second connecting assembly 20. This structural design is simple, has low manufacturing cost, and is suitable for mass production.

[0024] In practice, the connecting arc plate 21, the second plate stamping cover 22, and the second connecting pipe 23 are all integrally stamped structures, which are integrally processed by molds, effectively reducing the number of parts and assembly steps, and improving the overall strength, stability and manufacturing efficiency of the structure.

[0025] In practical implementation, the side of the plate stretching arc cover 11 is provided with a movable plate groove 111. The size of the movable plate groove 111 is larger than the size of the movable connecting arc plate 21. The movable connecting arc plate 21 is connected in the movable plate groove 111. The middle side of the plate stretching arc cover 11 is provided with a first movable through hole 112, and the middle side of the movable connecting arc plate 21 is provided with a second movable through hole 211. The first movable through hole 112 and the second movable through hole 211 correspond to each other and are hinged together by a connecting shaft passing through the first movable through hole 112 and the second movable through hole 211. Thus, the first connecting component 10 and the second connecting component 20 are movably hinged together. In use, through the above settings, the first connecting component 10 and the second connecting component 20 can be rotated and adjusted within the range of 0 degrees to 180 degrees. The included angle between the components can be flexibly adjusted according to the actual installation requirements of different tilt angles of the stair railing, improving the adaptability and convenience of installation and meeting the application requirements of different engineering environments.

[0026] In summary, the first connecting component 10 and the second connecting component 20 are movably hinged together. The plate stretching arc cover 11, the first plate stamping cover 12, and the first connecting pipe 13 are sequentially welded and fixed together. The plate stretching arc cover 11, the first plate stamping cover 12, and the first connecting pipe 13 are all integrally stamped and formed structures. The movable connecting arc plate 21, the second plate stamping cover 22, and the second connecting pipe 23 are sequentially welded and fixed together. The movable connecting arc plate 21, the second plate stamping cover 22, and the second connecting pipe 23 are all integrally stamped and formed structures. The connecting components of the movable structure guardrail stair accessory of this utility model adopt separate welding and fixed and integral stamping and forming, which simplifies the assembly steps, significantly improves the installation efficiency, reduces labor costs, and has low manufacturing costs.
