DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] Embodiment 1

[0022] As Figures 1-4 shown, a spliced frame with a 20-fold profile proposed in this embodiment includes a horizontal frame, a plurality of connecting beams 3, and a plurality of connectors 4.

[0023] The horizontal frames are horizontally distributed and arranged in two groups side by side in the vertical direction. The horizontal frame is a rectangular frame structure, including two first cross beams 1 and two second cross beams 2. A total of four connecting beams 3 are vertically arranged, and the first cross beam 1, the second cross beam 2, and the connecting beam 3 are perpendicularly distributed to each other.

[0024] A plurality of connecting beams 3 are distributed between the two groups of horizontal frames. The connecting beams 3 are vertically distributed, and the height of the connecting beams 3 determines the height of the entire frame.

[0025] The first cross beam 1, the second cross beam 2, and the connecting beam 3 are all 20-fold profile structures, and the thickness of the 20-fold profile structure is 2.5 mm. The 20-fold profile is produced by the rolling method on a rolling line. The first cross beam 1, the second cross beam 2, and the connecting beam 3 all have an inner joint surface 11 on the inner side and an outer joint surface 12 on the outer side, and the ends of the first cross beam 1, the second cross beam 2, and the connecting beam 3 have grooves 13.

[0026] A plurality of connectors 4 splice and connect the horizontal frame and the connecting beam 3. Each connector 4 is spliced and connected to a first cross beam 1, a second cross beam 2, and a connecting beam 3. The connector 4 has good versatility during connection and can connect the first cross beam 1, the second cross beam 2, and the connecting beam 3 with different lengths, as long as the end styles of the beams are the same. Of course, among the first cross beam 1, the second cross beam 2, and the connecting beam 3, the lengths of two beams can be equal, or the lengths of all three beams can be equal, and the connector 4 can also be used to connect the beams. The connector 4 has three mutually perpendicular abutting surfaces 401. On each abutting surface 401, there are a plug-in table portion a41, a plug-in table portion b42, and a plug-in table portion c43 that are clamped with the inner joint surface 11, and a plug-in table portion d44 that is clamped with the outer joint surface 12. The beams are installed by the clamping method, and the plug-in table portions can also play a positioning role when installing the beams. There is a clamping table portion 45 on the abutting surface 401 that can be clamped into the inner side of the groove 13. The clamping table portion 45 is used to be clamped into the groove 13 to further improve the stability of the overall structure.

[0027] In this embodiment, the overall structural regularity is accurately clamped and ensured through the splicing method. The plug-in table portion a41, the plug-in table portion b42, the plug-in table portion c43, the plug-in table portion d44, and the clamping table portion 45 on the three abutting surfaces 401 of the connector 4 can perform clamping and positioning during the splicing installation of the first cross beam 1, the second cross beam 2, and the connecting beam 3 with the profile structure form, ensuring the regularity and disassembly convenience of the overall frame structure, and can be assembled on-site according to the use requirements.

Compared with the first embodiment, in this embodiment, the first cross beam 1, the second cross beam 2 and the connecting beam 3 all have two inwardly recessed concave portions 14, and the concave portions 14 are located between the insertion table portion a41 and the insertion table portion c43, and the concave portions 14 are used to enhance the anti-disconnection effect when each profile is connected to the connector 4.

[0030] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited thereto, and various changes can be made without departing from the spirit of the present utility model within the scope of knowledge of those skilled in the art to which the present utility model pertains.
