Description

Technical Field

[0001] This utility model belongs to the field of container building technology, specifically relating to a connection structure for a double-wing expandable container house. Background Technology

[0002] my country's ongoing urbanization, large-scale infrastructure construction (transportation, energy, water conservancy), and industrial park development have generated a huge demand for efficient, temporary, or semi-permanent building facilities. Frequent natural disasters and public health emergencies place higher demands on rapidly deployable emergency command, medical, and resettlement sites. The double-wing expandable container house is a modular building unit based on the expansion of standard shipping container modules. These standard container modules are typically 20-foot or 40-foot standard containers. Through a sophisticated mechanical structure and control system, the two side walls ("wings") of the double-wing expandable container house are moved outwards horizontally or tilted, allowing it to maintain the dimensions of a standard container during transport. Upon arrival at the usage site, it can expand to one or even two times the original container's internal usable area. To address the connection stability of the container panels and improve the efficiency of assembly and disassembly, a suitable connection structure for the double-wing expandable container house should be provided.

Detailed Implementation

[0021] like Figure 1 As shown, this utility model includes a first hinge assembly for connecting the middle or end of two adjacent square tube frames of an expansion box and a second hinge assembly for connecting the ends of two adjacent square tube frames of an expansion box. The first hinge assembly includes a first U-shaped mounting base 1 and a U-shaped connecting plate 2-1. The second hinge assembly includes a second U-shaped mounting base 3 and a U-shaped clamping plate 4-1. The first U-shaped mounting base 1 and the U-shaped connecting plate 2-1, as well as the second U-shaped mounting base 3 and the U-shaped clamping plate 4-1, are connected by a spring pivot shaft 5. The axis of the spring pivot shaft 5 is parallel to the length direction of the square tube frame of the expansion box.

[0022] In this embodiment, the middle or end of two adjacent expansion box square tube frames are hinged by a first hinge assembly, which includes a first U-shaped mounting base 1 and a U-shaped connecting plate 2-1. The ends of two adjacent expansion box square tube frames are hinged by a second hinge assembly, which includes a second U-shaped mounting base 3 and a U-shaped clamping plate 4-1. In actual use, the expansion box square tube frames include vertical square tube frames 6 and horizontal square tube frames 7. The first hinge assembly can be used for hinged connections between the middle or end of two adjacent vertical square tube frames 6, or between the middle or end of two adjacent horizontal square tube frames 7. The second hinge assembly can be used for hinged connections between the ends of two adjacent vertical square tube frames 6, or between the ends of two adjacent horizontal square tube frames 7.

[0023] like Figure 1As shown, during actual installation, the first hinge assembly connects the middle of two adjacent vertical square tube frames 6, and the second hinge assembly connects the ends of two adjacent vertical square tube frames 6. This requires fixing the first U-shaped mounting base 1 and the U-shaped connecting plate 2-1 to the middle of the two vertical square tube frames 6 respectively, and connecting the first U-shaped mounting base 1 and the U-shaped connecting plate 2-1 via a spring pivot shaft 5. The second U-shaped mounting base 3 is fixedly installed at the end of one vertical square tube frame 6, and the U-shaped clamping plate 4-1 is fixedly installed at the end of the other vertical square tube frame 6. The U-shaped clamping plate 4-1 will clamp onto the horizontal square tube frame 7 of the adjacent box panel. Since the opening of the U-shaped clamping plate 4-1 faces downwards or upwards, it can only be fixedly installed on the horizontal square tube frame 7. Therefore, the second hinge assembly can only be used for hinged connections at the ends of two adjacent expansion box square tube frames.

[0024] In this embodiment, the first U-shaped mounting base 1, the U-shaped connecting plate 2-1, the second U-shaped mounting base 3, and the U-shaped clamping plate 4-1 are all fixedly installed on the vertical square tube frame 6 or the horizontal square tube frame 7 by means of fastening bolts or welding. The U-shaped clamping and fixing results in high structural connection stability, flexible rotation of the spring central shaft 5, and convenient installation, disassembly, and replacement. This can solve the problems of difficult relocation of the double-wing expandable container house and the difficulty of subsequent replacement and maintenance.

[0025] In this embodiment, during actual installation, as follows: Figure 2 and Figure 3 As shown, in this embodiment, the first U-shaped mounting base 1 includes a first U-shaped steel plate 1-1 for mounting on the square tube frame of the expansion box and a grooved bending plate 1-2 disposed on the first U-shaped steel plate 1-1. The opening direction of the grooved bending plate 1-2 is opposite to the opening direction of the first U-shaped steel plate 1-1. The U-shaped connecting plate 2-1 is provided with a U-shaped protrusion 2-2 for mounting on the grooved bending plate 1-2.

[0026] like Figure 4 and Figure 5 As shown, in this embodiment, the second U-shaped mounting base 3 includes a second U-shaped steel plate 3-1 for mounting on the frame of the square tube of the expansion box and an L-shaped bent plate 3-2 disposed on the second U-shaped steel plate 3-1. The opening direction of the U-shaped mounting plate 4-1 is downward or upward, and a rectangular block 4-2 is disposed on the bottom surface of the web of the U-shaped mounting plate 4-1.

[0027] like Figure 5 and Figure 6As shown, during actual installation, since the U-shaped mounting plate 4-1 needs to be mounted on the end of the vertical square tube frame 6 or the horizontal square tube frame 7, the rectangular block 4-2 needs to be able to be inserted into the square hole of the vertical square tube frame 6 or the horizontal square tube frame 7. That is, the periphery of the rectangular block 4-2 needs to reserve an insertion space that matches the wall thickness of the vertical square tube frame 6 or the wall thickness of the horizontal square tube frame 7.

[0028] like Figures 2 to 6 As shown, in this embodiment, the inner surfaces of the two side plates of the grooved bending plate 1-2 and the bottom surface of the horizontal plate of the L-shaped bending plate 3-2 are provided with first mounting holes 8. The two end faces of the U-shaped protrusion 2-2 and the web of the U-shaped clamping plate 4-1 are provided with second mounting holes 9. The second mounting holes 9 on the web of the U-shaped clamping plate 4-1 extend into the rectangular block 4-2. The fixed end of the spring rotating shaft 5 is installed in the second mounting hole 9, and the telescopic end of the spring rotating shaft 5 is installed in the first mounting hole 8.

[0029] In this embodiment, both the first mounting hole 8 and the second mounting hole 9 are blind holes. The two side plates of the grooved bending plate 1-2 and the horizontal plate of the L-shaped bending plate 3-2 are provided with disassembly holes 10 arranged coaxially with the first mounting hole 8.

[0030] In actual use, when it is necessary to disassemble the spring pivot shaft 5, insert a steel wire or steel needle into the disassembly hole 10 to squeeze the telescopic end of the spring pivot shaft 5, so that the telescopic end of the spring pivot shaft 5 is disassembled from the first mounting hole 8. Disassembly is convenient, easy to operate, and saves time and effort.

[0031] The above description is merely a preferred embodiment of the present utility model and does not constitute any limitation on the present utility model. Any simple modifications, alterations, or equivalent structural changes made to the above embodiments based on the technical essence of the present utility model shall still fall within the protection scope of the present utility model.
