High-strength steel profile suitable for switch cabinet body frame

Abstract

The utility model discloses a high-strength steel profile suitable for a switch cabinet body frame, and belongs to the technical field of low-voltage switch cabinet body manufacturing. The high-strength steel profile suitable for the switch cabinet body frame comprises a steel profile body and a steel profile connecting plate, a first bent part is arranged on the side face of the steel profile body, and a second bent part is arranged on the side face of the first bent part. According to the high-strength steel sectional material suitable for the switch cabinet body frame, when acting force acts on the interior of the steel sectional material body, the steel sectional material connecting plate is preferentially extruded by the acting force and can resist the corresponding acting force, and due to the fact that the high-strength steel sectional material is used in a switch cabinet, sectional material reinforcing ribs are arranged in the high-strength steel sectional material, and a bent sealing edge and two sealing edges in the steel sectional material body are matched; the acting force is further resisted. The problem of insufficient strength of the standard section bar when the cabinet body is reinforced can be effectively solved, the condition of bearing deformation of the section bar is avoided, and the strength is ensured under the condition that the cost is not greatly increased.

Description

Technical Field

[0001] The utility model relates to the technical field of low-voltage switch cabinet manufacturing, in particular to a high-strength steel profile suitable for a switch cabinet frame. Background Art

[0002] With the development of domestic power distribution technology, there are many kinds of existing steel profiles, the most typical of which are C profiles and 8MF profiles. Profiles of this structure are widely used. The advantages are simple structure, flexible combination, easy installation, and the cost is much lower than aluminum profiles of the same specifications.

[0003] Since the above two commonly used profiles have their own advantages and disadvantages, for example, due to the simple assembly structure, the C profile has poor rigidity and strength after assembly, and the load capacity after assembly into the switch cabinet is limited. Especially after being used in large quantities in the primary distribution equipment, its stability and cabinet strength cannot meet the requirements of high strength and dynamic stability of the switch cabinet during the operation of the distribution cabinet. The strength of the 8MF profile is better than that of the C profile, but the 8MF profile is made of hot-rolled steel plates and needs to be processed by welding, grinding, pickling, phosphating, spraying and other processes. The manufacturing process is complicated and not environmentally friendly, and the use of the C profile will cause the problem of insufficient strength. Utility Model Content

[0004] The utility model aims to solve the problem of insufficient strength when using C-shaped materials in the prior art. To this end, the utility model proposes a high-strength steel profile suitable for the switch cabinet frame, which can ensure strength without significantly increasing costs.

[0005] A high-strength steel profile suitable for a switch cabinet frame comprises a steel profile body and a steel profile connecting plate, wherein a first bending portion is arranged on the side of the steel profile body, a second bending portion is arranged on the side of the first bending portion, a third bending portion is arranged on the bottom of the second bending portion, and the side of the third bending portion is disconnected along its length direction to form a closed edge.

[0006] Furthermore, two groups of the first bending portions are provided, and the two groups of the first bending portions are symmetrically distributed about the central axis of the steel profile body.

[0007] Furthermore, the third bending portion and the closed edge are located between the second bending portion and the steel profile body.

[0008] Furthermore, a first nut passing hole is provided on the steel profile body, a circular connecting hole is provided on the first bent portion, a second nut passing hole is provided on the second bent portion, an auxiliary connecting hole is provided on the third bent portion and the closed edge, a third nut passing hole is provided on the third bent portion and the closed edge, and profile reinforcement ribs are fixedly connected to the tops of both sides of the steel profile connecting plate.

[0009] Furthermore, two groups of second nut passing holes are formed on the second bending portion.

[0010] Furthermore, the third nut passing hole is located at a top side position of the auxiliary connecting hole.

[0011] The difference from the prior art is that the beneficial effects of this application are:

[0012] This high-strength steel profile suitable for the switch cabinet frame, when the force acts on the steel profile body, the steel profile connection plate is first squeezed by the force, which can resist the corresponding force, and because it is used in the switch cabinet, it is equipped with profile reinforcement ribs, and combined with the bent closed edges inside the steel profile body, the two closed edges can further resist the force. It can effectively solve the problem of insufficient strength of standard profiles when strengthening the cabinet, avoid the deformation of the profile under load, and ensure strength without significantly increasing costs.

A first bending portion 200 is provided on the side of the steel profile body 100. Two groups of the first bending portions 200 are provided. The two groups of first bending portions 200 are symmetrically distributed about the central axis of the steel profile body 100. The first bending portion 200 also buffers the applied force to a certain extent. A second bending portion 300 is provided on the side of the first bending portion 200, and a third bending portion 400 is provided at the bottom of the second bending portion 300. The provision of the third bending portion 400 can further buffer the applied force. The side of the third bending portion 400 is disconnected along its length direction to form a closed edge 500. The third bending portion 400 and the closed edge 500 are located between the second bending portion 300 and the steel profile body 100. Because the closed edge 500 is located between the second bending portion 300 and the steel profile body 100, the applied force is further buffered. A through first nut through hole 600 is provided on the steel profile body 100. The aluminum-zinc coated steel plate is used for processing, and a "C" profile module hole is punched on the upper part, which is symmetrical on both sides. The two sides are first folded and flattened, and then the left and right sides are formed after three bends. A through circular connection hole 700 is provided on the first bending portion 200, a through second nut through hole 800 is provided on the second bending portion 300, two groups of second nut through holes 800 are provided on the second bending portion 300, a through auxiliary connection hole 900 is provided on the third bending portion 400 and the closed edge 500, and a through third nut through hole 1000 is provided on the third bending portion 400 and the closed edge 500, and the third nut through hole 1000 is located on the top side of the auxiliary connection hole 900. Through the auxiliary connection hole 900 and the third nut through hole 1000, nuts can be used to fix the third bending part 400 and the closed edge 500, which have a total of four layers. The top of the two sides of the steel profile connecting plate 1200 are fixedly connected with the profile reinforcement ribs 1100, so that the problem of insufficient strength of the standard profile when strengthening the cabinet can be effectively solved, and the deformation of the profile under load can be avoided, and the strength can be guaranteed without significantly increasing the cost.

[0028] When in use, when the force acts on the steel profile body 100, the steel profile connecting plate 1200 is first squeezed by the force, and can resist the corresponding force. Because it is used in the switch cabinet, the profile reinforcement rib 1100 is provided inside, and the two closed edges 500 are combined with the bent closed edge 500 inside the steel profile body 100 to further resist the force. It can effectively solve the problem of insufficient strength of standard profiles when strengthening the cabinet, avoid the deformation of the profile under load, and ensure strength without significantly increasing the cost.
