Description

The crossbeam of distribution, communication cabinet

Technical field

The skeleton that the utility model relates to distribution, communication cabinet supports, especially a kind of crossbeam for distribution, communication cabinet.

Background technology

The column of distribution, communication cabinet needs crossbeam to be fixed, side plate also needs crossbeam to fix, and the quality of crossbeam directly has influence on quality and the useful life of distribution, communication cabinet, and the two ends of most of crossbeam are empty, for the firmness that increases crossbeam two ends and fixing with column, need by welding, the location-plate of burn-oning at the two ends of crossbeam is corroded and increases aesthetics in order to prevent location-plate, whole crossbeam need to be carried out electroplating processes, cost is high, and is time-consuming, and the feature of environmental protection is poor; And in crossbeam and column assembling process, zinc-plated crossbeam and column (galvanized sheet or aluminizing zine plate) color produces obvious difference.

also having some crossbeams is welding crossbeams, adopt a metallic plate to process by the processing technology of the required hole of punching press and folding, compare with the crossbeam of needs welding, process stabilizing, aesthetics is high, need not to electroplate, cost is low, work simplification, high efficiency, but end socket (need being equivalent to the location-plate at the welding beam two ends) sheet metal thickness at this welding crossbeam two ends is little, be connected with column and use after all easily cause the distortion of end socket, and the beam strength of producing by the processing technology of folding is not high, the curve transition section of crossbeam and end socket is easily broken, in addition, increase the reinforcement difficulty higher on such crossbeam, complex process, also not attractive in appearance.

The utility model content

The technical problems to be solved in the utility model is: based on the problems referred to above, provide a kind of difference that solves crossbeam and other structural member material color, intensity is high, work simplification, the distribution of attractive in appearance, environmental protection, the crossbeam of communication cabinet.

The technical scheme that its technical problem that solves the utility model adopts is: the crossbeam of a kind of distribution, communication cabinet, described crossbeam has base plate, one side of base plate is extended with the first flanging and the second flanging that forms after twice bending, the opposite side of base plate is extended with the 3rd flanging that forms after a bending, the two ends of described crossbeam also have the end socket that connects with column of cabinet body for crossbeam, described end socket forms after extending bending by base plate, also has the enhancing flanging of extension on the edge of described end socket.

In order to strengthen the intensity of end socket, on described end socket corresponding to enhancing flanging and the riveted joint of the first flanging at the first flanging place.

For the curve transition section that prevents crossbeam base plate and end socket in use ruptures, also be suppressed with the enhancing beading at described base plate and end socket curve transition place.

Crossbeam for long in order to prevent bottom deformation, is distributed with at least one place through the reinforcement of compression molding on described base plate.

In order to facilitate being connected of crossbeam and column, also be suppressed with location and positive stop lug boss corresponding to hole on column of cabinet body on described end socket.

The beneficial effects of the utility model are: end socket of the present utility model forms after extending bending by the crossbeam base plate, global formation, work simplification; The enhancing flanging that also has extension on the edge of end socket has strengthened the intensity of end socket, has increased the useful life of crossbeam, this crossbeam end socket place can satisfy requirement of strength, do not need again the soldering in later stage, can not the deface zinc coat, not only attractive in appearance, also environmental protection.

Embodiment

By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, basic structure of the present utility model only is described in a schematic way, so it only show the formation relevant with the utility model.

As shown in Fig. 2～4, the crossbeam of a kind of distribution, communication cabinet, crossbeam 1 has base plate 11, one side of base plate 11 is extended with the first flanging 12 and the second flanging 13 that forms after twice bending, the opposite side of base plate 11 is extended with the 3rd flanging 14 that forms after a bending, the two ends of crossbeam 1 also have the end socket 15 that connects with column of cabinet body for crossbeam 1, and end socket 15 forms after extending bending by base plate 11, also has the enhancing flanging 151 of extension on the edge of end socket 15.

In order to strengthen the intensity of end socket 15, on end socket 15 corresponding to enhancing flanging 151 and first flanging 12 riveted joints at the first flanging 12 places.

For the curve transition section that prevents crossbeam base plate 11 and end socket 15 in use ruptures, also be suppressed with at described base plate 11 and end socket 15 curve transition places and strengthen beading 16.

For long crossbeam 1, in order to prevent base plate 11 distortion, be distributed with at least one place on base plate 11 through the reinforcement 17 of compression molding.

In order to facilitate being connected of crossbeam 1 and column, also be suppressed with location and positive stop lug boss 152 corresponding to hole on column of cabinet body on end socket 15.

The two ends of crossbeam 1 can form the end socket 15 that connects with column of cabinet body by processing technologys such as folding or mold pressings, and simultaneously, the enhancing flanging 151 on end socket 15 also forms by processing technologys such as folding or mold pressings; Corresponding to enhancing flanging 151 and first flanging 12 riveted joints at the first flanging 12 places, for the ease of connecting, strengthen on flanging 151 and have one section elongated portion on end socket 15.

In order to reach the technological requirement of high-strength crossbeam structure, can also pass through multiple pressure technology groove, process bar, the size that perhaps increases and decreases stiffened edge reaches.

Take above-mentioned foundation desirable embodiment of the present utility model as enlightenment, by above-mentioned description, the relevant staff can in the scope that does not depart from this utility model technological thought, carry out various change and modification fully.The technical scope of this utility model is not limited to the content on specification, must determine its technical scope according to the claim scope.
