DETAILED DESCRIPTION

[0019] Embodiment 1

[0020] like Figure 1-Figure 3 As shown, the embodiment provides a 24-fold profile frame that is easy to install, including side frames, connecting beams c3 and connectors 4. The side frames are arranged in two groups horizontally and symmetrically, including two connecting beams a1 distributed horizontally and two connecting beams b2 distributed vertically, and the two connecting beams a1 and the two connecting beams b2 are distributed in a rectangular shape. Four connecting beams c3 are distributed horizontally, and the eight ends of the four connecting beams c3 are respectively oriented toward the eight corners of the two groups of side frames.

[0021] There are eight connectors 4, which are respectively distributed at the eight corners of the two sets of side frames, and each connector 4 is respectively connected with a connecting beam a1, a connecting beam b2 and a connecting beam c3. The eight connectors 4 can connect the four connecting beams a1, the four connecting beams b2 and the four connecting beams c3 into a rectangular structure as the frame of the control cabinet.

[0022] The connecting beam a1, the connecting beam b2 and the connecting beam c3 are all twenty-four fold profiles with high structural strength. The connecting beam a1, the connecting beam b2 and the connecting beam c3 have the same cross-sectional profile. The profiles are roll-formed by a rolling line and the profile thickness is 2.5 mm.

[0023] The connector 4 has three mutually perpendicular abutting surfaces 401, and the connecting beams a1, b2 and c3 are perpendicular to each other. The connector 4 has one inserting platform a41, two inserting platforms b42, two inserting platforms c43, one inserting platform d44 and a plurality of clamping platforms 45 on each abutting surface 401, and the two inserting platforms b42 and the two inserting platforms c43 are symmetrically distributed about the inserting platform a41, so after the connector 4 is connected to the connecting beam, the balance and stability of the connection can be guaranteed.

[0024] The connecting beam a1, the connecting beam b2 and the connecting beam c3 all have an inner clamping surface a11 and an outer clamping surface b12. The clamping surface a11 is clamped on the outer surfaces of the plug-in parts a41, b42 and c43, and the clamping surface b12 is clamped on the inner side surface of the plug-in part d44. That is, the connecting beam can be inserted between the plug-in parts a41, b42, c43 and d44, and the connection reliability is good.

[0025] The ends of the connecting beams a1, b2 and c3 all have a slot 13 for engaging with the platform 45. The ends of the connecting beams are engaged with the platform 45 through the slot 13, further improving the stability of the frame structure after connection.

[0026] The outer ends of the inserting portion a41, the inserting portion b42 and the inserting portion c43 are all chamfered, so when installing the connecting beam, the connecting beam in the form of a profile can be guided by the chamfer and smoothly inserted into the connecting head 4.

[0027] This embodiment can effectively improve the structural strength, deformation resistance, and earthquake resistance, and is easy to install. The adjacent ends of three connecting beams can be connected through a connector 4, and a total of eight connectors 4 are required to firmly connect the twelve connecting beams into a frame structure, which firmly supports the entire control cabinet on the inside of the control cabinet. The frame structure is very convenient to install. When it needs to be transported, it can be transported in the form of parts for easy transportation, and then installed on site at the use site.

[0028] Embodiment 2

[0029] like Figure 1-Figure 3 As shown, the embodiment proposes a 24-fold profile frame that is easy to install. Compared with the first embodiment, in the embodiment, the connecting beam a1, the connecting beam b2 and the connecting beam c3 all have a concave inner convex portion a14 and a concave inner convex portion b15, the inner convex portion a14 is located between the inserting platform portion a41 and the inserting platform portion c43, and the inner convex portion b15 is located between the two inserting platforms c43. By providing the inner convex portion a14 and the inner convex portion b15, the structural strength of the connecting beam in the form of the entire profile structure can be further improved, and the inner convex portion a14 and the inner convex portion b15 can also effectively prevent the disengagement through the inserting platform portion a41 and the inserting platform portion c43.

[0030] The implementation modes of the present invention are described in detail above in conjunction with the accompanying drawings, but the present invention is not limited thereto, and various changes can be made within the knowledge scope of technicians in the relevant technical field without departing from the purpose of the present invention.
