DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1 to Figure 3In an embodiment of the utility model, a positioning device for processing a power distribution switch cabinet comprises two vertical mounting bars 1 vertically mounted in the power distribution switch cabinet, a plurality of mounting holes 2 are vertically and equidistantly opened on the vertical mounting bars 1, and the vertical mounting bars 1 are pre-connected with the horizontal mounting bars 3 through a positioning mechanism;

[0021] The horizontal mounting bar 3 is connected to the mounting plate 6 via a connecting mechanism, and the connecting mechanism is used to fix the mounting plate 6 to the end surface of the horizontal mounting bar 3;

[0022] Connecting holes 4 are provided at both ends of the horizontal mounting bar 3 . The positioning mechanism is connected to the back end of the horizontal mounting bar 3 and aligned with the connecting holes 4 . The positioning mechanism is used to pre-connect the horizontal mounting bar 3 to the front end surface of the vertical mounting bar 1 .

[0023] In this embodiment: when the power distribution switch cabinet is manufactured, at the final stage of the manufacturing process, electrical equipment (such as circuit breakers and other equipment) needs to be installed in the power distribution switch cabinet. First, two vertical mounting bars 1 are symmetrically fixed in the inner cavity of the power distribution switch cabinet, the electrical equipment is fixed to the positive end of the mounting plate 6 on the outside, and the horizontal mounting bar 3 is installed to the back end of the mounting plate 6 through a connecting mechanism;

[0024] After the horizontal mounting bar 3 is fixed, the integrated electrical equipment, mounting plate 6, horizontal mounting bar 3 and vertical mounting bar 1 are connected, and the positioning mechanism is inserted into the mounting hole 2 to realize the positioning engagement of the horizontal mounting bar 3 and the mounting hole 2, and the horizontal mounting bar 3 is pre-positioned. At this time, no assembly personnel are required, and they can continue to hold the integrated electrical equipment, mounting plate 6 and horizontal mounting bar 3 for easy assembly.

[0025] Please refer to Figure 1 , Figure 2 and Figure 3 The positioning mechanism includes a docking ring assembly 9 fixedly connected to the back end of the horizontal mounting bar 3, the docking ring assembly 9 includes an upper docking ring 901 and a lower docking ring 902 symmetrically arranged, and a gap 10 is provided between the upper docking ring 901 and the lower docking ring 902;

[0026] The upper docking ring 901 and the lower docking ring 902 are both formed with a conical surface 11 at one end away from the horizontal mounting bar 3. The diameter of the narrow edge of the conical surface 11 is smaller than the diameter of the mounting hole 2, and the diameter of the wide edge of the conical surface 11 is larger than the diameter of the mounting hole 2.

[0027] In this embodiment: when the positioning mechanism is docked with the mounting hole 2, the narrow end edge of the conical surface 11 is docked with the mounting hole 2. When the narrow surface enters the mounting hole 2, the narrow surface is smaller than the mounting hole 2. As the conical surface 11 is inserted, the diameter of the conical surface 11 entering the mounting hole 2 gradually increases until the conical surface 11 contacts and squeezes the inner wall of the mounting hole 2. At this time, the squeezing force acts on the upper docking ring 901 and the lower docking ring 902, and the upper docking ring 901 and the lower docking ring 902 are squeezed and deformed, and the gap 10 provides an effective deformation space for the upper docking ring 901 and the lower docking ring 902.

[0028] The friction force generated by the squeezing force effectively clamps the upper docking ring 901 and the lower docking ring 902 in the inner cavity of the mounting hole 2. At this time, the assembler does not need to hold the integrated electrical equipment, the mounting plate 6 and the horizontal mounting bar 3, so the operator can tighten the pre-fixed horizontal mounting bar 3 with both hands.

[0029] During the bolting process, the diameter of the bolt inserted between the upper docking ring 901 and the lower docking ring 902 should be smaller than the diameter of the narrow end after deformation. After insertion, the matching nut is tightened, and the end of the bolt and the end of the nut form an extrusion force to achieve bolting and fixing.

[0030] Please refer to Figure 1 and Figure 2 The connection mechanism includes a plurality of docking holes 5 which are opened transversely inside the transverse mounting strip 3 and are equidistantly opened between the two connection holes 4.

[0031] and long slots 7 are provided at the upper and lower ends of the mounting plate 6, and bolts pass through the long slots 7 and are connected to the docking holes 5 and nuts;

[0032] Two symmetrical connecting notches 8 are provided in the middle of the front end surface of the mounting plate 6, and the connecting notches 8 are connected to the electrical equipment through connecting bolts.

[0033] In this embodiment: align and dock the bolt holes or docking blocks on the back of the electrical equipment with the connection slots 8 and effectively fix them (e.g., bolting with bolts and screw holes);

[0034] Then align the docking hole 5 on the horizontal mounting bar 3 with the long slot 7, and keep the protruding lengths of the two ends of the horizontal mounting bar 3 equal, then use bolts to penetrate the long slot 7 and the docking hole 5, and use nuts to tighten them, to complete the installation of the horizontal mounting bar 3 and the mounting plate 6, and realize the integration of the electrical equipment, the mounting plate 6 and the horizontal mounting bar 3, and then fix the integrated electrical equipment, the mounting plate 6 and the horizontal mounting bar 3 on the vertical mounting bar 1.

[0035] What is described above is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
