Abstract

The utility model discloses a corner connector for connecting a transverse beam, a vertical beam and a column sectional bar on the corner of a cabinet frame, wherein two mutually orthogonal side surfaces of a square axle of the corner connector extend from a transverse beam connection part and a vertical beam connection part, and a column connection part is vertically arranged on the rear part of the square axle. The frame sectional bars such as the column, the transverse beam and the vertical beams are internally supported by the solid connection parts of the corner connector, and then positioned and supported by step surfaces, and locked, welded and reinforced by fasteners, so as to connect and fix the frame corners. Compared with the prior art of only using the welding way as the connection way of the sectional bar, the corner connector not only facilitates the manufacture and installation, but also greatly improves the connection strength, reliability and safety of the device.

Background technology

The regulator cubicle cabinet adopts section bar to assemble usually; When adopting common sixteen fold section bar to carry out the cabinet assembling; In the bight of cabinet, i.e. three intersection point places of orthogonal coordinates of forming of the crossbeam of base, longeron and column section bar, its common fit is to adopt like the disclosed structure of patent " CN 97199815-has the switch cubicle of a framework "; Promptly at first the end face of crossbeam, longeron is cut into 45 degree oblique angles, it is corresponding with column section bar cross sectional shape that punching out goes out otch; Earlier crossbeam and longeron quadrature are spliced to form base, and then column vertically is placed on incision welds.Though this structure need not used extra corner connector; But the processing capacity to crossbeam, longeron is bigger; And dimensional accuracy is relatively stricter, also need anchor clamps to position in the welding process, thereby the scene that is difficult in makes; And the cabinet size that assembles is very big, has increased cost of transportation and complexity.And in the actual use, when whole rack full load load was very big, higher cabinet column was very big at the moment of torsion that the foot pad produces, thereby thin pad is easy to destroy, and damaged thereby cabinet takes place.

The utility model content

The applicant adopts welding manner to connect crossbeam, longeron and column to above-mentioned existing regulator cubicle cabinet in the bight; Not only processing capacity is big; And be welded to connect shortcomings such as poor performance; A kind of Corner Link rational in infrastructure is provided, thereby can carries out three connection easily and fast, and reliability is effectively improved.

The technical scheme that the utility model adopted is following:

A kind of Corner Link; Be used to connect crossbeam, longeron and the column section bar in cabinet body frame bight; Crossbeam connecting portion and longeron connecting portion are extended in the mutually orthogonal two sides of the square shaft body of Corner Link, and the shape of crossbeam connecting portion and longeron connecting portion is corresponding with the shape and the size of the medial surface of crossbeam and longeron respectively; The end face of square shaft body is higher than the end face and the bottom surface of crossbeam connecting portion and longeron connecting portion, has formed vertical step; The rear portion of square shaft body is provided with middle deck; On middle deck, vertically be provided with the column connecting portion; The column connecting portion is corresponding with the medial surface shape and the size of column, and the size of middle deck is slightly larger than the bed-plate dimension of column connecting portion; And there is the gap between column connecting portion and the square shaft body, formed horizontal bench.

Further improvement as technique scheme: the water proof sheet is arranged on the square shaft body side surface, is the both wings of inclination certain angle.

Side at each connecting portion is provided with screwed hole.

The beneficial effect of the utility model is following:

The utility model utilizes frame section bars such as each solid connecting portion column of Corner Link, horizontal longeron to carry out inner support; Utilize the location and the support of each step surface implementation framework section bar; Again through securing member locking and reinforcement of weld, formed connection to the framework bight with fixing; Compare with prior art in only depend on the connected mode of fabricated structural shape sheet material, not only made things convenient for and made and install, and improved bonding strength greatly, increased the reliability and security of equipment.

Embodiment

Below in conjunction with accompanying drawing, the embodiment of the utility model is described.

Like Fig. 1, shown in Figure 2; The described Corner Link 9 of the utility model extends crossbeam connecting portion 1 and longeron connecting portion 2 in the mutually orthogonal two sides of square shaft body 5; Crossbeam connecting portion 1 is corresponding with the shape and the size of the medial surface of longeron 12 with crossbeam 11 respectively with the shape of longeron connecting portion 2; The end face of square shaft body 5 is higher than the end face and the bottom surface of crossbeam connecting portion 1 and longeron connecting portion 2, thereby has formed vertical step 4.After installation, like Fig. 3, shown in Figure 4, vertically step 4 connects with the end face of crossbeam 11 with longeron 12, thereby realizes the location.

Like Fig. 1, shown in Figure 2; The rear portion of square shaft body 5 is provided with middle deck 8, on middle deck 8, vertically is provided with column connecting portion 3, and column connecting portion 3 is corresponding with the medial surface shape and the size of column 10; The size of middle deck 8; Be slightly larger than the bed-plate dimension of column connecting portion 3, and have the gap between column connecting portion 3 and the square shaft body 5, thereby formed horizontal bench 7.After installation, like Fig. 3, shown in Figure 4, the end face of column 10 is carried on the horizontal bench 7, has realized location and supporting.In the side of each connecting portion, also be provided with screwed hole, the installing hole that after assembling, can utilize securing member to pass the section bar side is fixed.

Water proof sheet 6 is arranged on square shaft body 5 sides, for the both wings of inclination certain angle, after installation; Water proof sheet 6 is connected with the water proof bar of crossbeam or longeron mutually, thereby can guide current, makes it import the drainage in cabinet bight; It is inner to prevent that current from flowing into cabinet, causes the electrical safety accident.

The 14 fold-type materials that the column 10 of the utility model can adopt the applicant to research and develop also can use sixteen fold section bar commonly used or other section bars, and the shape that only need change column connecting portion 3 according to the inside dimensions of column section bar flexibly gets final product.Equally, crossbeam 11 and longeron 12 also can adopt the section bar of plurality of specifications.

The column 10 of the utility model, crossbeam 11 only need directly block when getting the raw materials ready with longeron 12 and get final product, and end face is a vertical cross-section, and need not be cut into the oblique angle, also need not cut out otch, have saved the workload of section bar processing greatly.Rely on the vertical step 4 and horizontal bench 7 of Corner Link 9 simultaneously, can realize Primary Location to section bar easily, improved installation effectiveness greatly.Thereby utilize the cabinet of the utility model assembling, and in transportation, can disassemble and be part independently, assemble fast at the scene, reduced the difficulty and the cost of transportation.

After cabinet body frame is put up in preliminary assembling; Soldering is carried out in the junction; Like Fig. 5, shown in Figure 6, the utility model forms first weld part 13, second weld part 14, the 3rd weld part 15 and the 4th weld part 16 between each frame section bar (crossbeam 11, longeron 12 and column 10), between section bar and Corner Link 9, weld; The 4th weld part 16 that these weld parts are especially vertical; Weld strength is very good, can improve the antitorque apart from ability of column greatly, prevents that solder joint is destroyed.
