Abstract
The utility model discloses a low-voltage switch framework which belongs to the technical field of low-voltage switch cabinets, comprising a first sectional material which is vertically arranged and a second sectional material which is horizontally arranged, wherein the first sectional material and the second sectional material form two rectangular frame bodies in an enclosing way. The four top points of the two frame bodies are connected through a third sectional material. First connectors are arranged on the top points of the frame bodies. The first connector comprises three extending parts which are vertical to one another, and the ends of the three extending parts are fixed together. First through holes are formed in the extending parts; second through holes are formed in the fist sectional material, the second sectional material and the third sectional material; and bolts are connected with nuts after passing through the first through holes and the second through holes. Compared with the original welding and fixing methods, the sectional materials for forming the frame bodies are connected together through the bolts and the nuts, so that the operation is convenient, and the technical requirements on workers are low.
Description
Technical field
The utility model belongs to the low-tension switch cabinet technical field, especially relates to a kind of low tension switch framework.
Background technology
Low-tension switch cabinet is applicable to industries such as power plant, oil, chemical industry, metallurgy, weaving, skyscraper, as the usefulness of transmission of electricity, distribution and electric energy conversion.
Low-tension switch cabinet mainly comprises cabinet and the components and parts composition that is arranged in the cabinet, and cabinet is generally rectangular shape, all is provided with iron sheet on six faces of cabinet.Because the volume of cabinet is generally all bigger,,, iron sheet is fixed on forms cabinet on the framework again so generally all be to constitute framework through section bar so depend merely on the shape that iron sheet can't support cabinet.
The method that traditional section bar constitutes framework mainly is to utilize welding that section bar is formed framework, welds this mode, inconvenient operation, and also very high to workman's specification requirement, therefore be necessary to improve.
Summary of the invention
The utility model provides a kind of low tension switch framework to deficiency of the prior art, need not welding, and is easy to operate, lower to workman's specification requirement.
For solving the problems of the technologies described above; The utility model is able to solve through following technical proposals: a kind of low tension switch framework; Comprise first section bar of vertical layout and second section bar of transverse arrangement of turbo, said first section bar and said second section bar surround two rectangular frameworks, and the place, four summits of two said frameworks links to each other through the 3rd section bar; The place, summit of said framework is provided with first connector; Said first connector comprises three orthogonal extensions, and an end of three said extensions is fixed together, and said extension is provided with first through hole; The two ends of said first section bar, said second section bar and said the 3rd section bar are provided with second through hole, and bolt passes said first through hole and is connected with nut later with said second through hole.
In the technique scheme, preferred, the shape of cross section of said first section bar, said second section bar and said the 3rd section bar all is " L " shape, and the shape of cross section of said extension is " L " shape.
In the technique scheme; Preferably; Also comprise second connector, said second connector comprises brace, and the two ends of said brace are provided with third through-hole; The centre position of said brace is fixed with two orthogonal said extensions, and plane, two said extension places is vertical with said brace.
The beneficial effect of the utility model is: the section bar of forming framework links together through screw bolt and nut, compares the original fixing mode of employing welding, and is easy to operate, low to workman's specification requirement.

Fig. 2 is the schematic perspective view of first section bar.
Fig. 3 is the sketch map of first connector.
Fig. 4 is the sketch map of second connector.
Embodiment
Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail: referring to Fig. 1 to Fig. 4; A kind of low tension switch framework comprises first section bar 2,3 of vertical layout, second section bar 1 of transverse arrangement of turbo; The 3rd section bar 4, the first connector heads 5 and second connector 6.First connector, 5 first connectors 5 comprise three orthogonal extensions 8, and an end of three said extensions 8 is fixed together, and all form first through hole 81 on each extension 8. First section bar 2,3; The two ends of second section bar 1 and the 3rd section bar 4 are provided with second through hole 71; Bolt passes first through hole 81 and is connected with nut with second through hole 71 back, and first connector 5 and first section bar, 2,3, the second section bars 1 and the 3rd section bar 4 are fixed together.Second connector 6, said second connector 6 comprises brace 9, and the two ends of brace 9 form third through-hole 91, and it is vertical with said brace 9 that the centre position of brace 9 is fixed with plane, 8, two extension 8 places of two orthogonal extensions.The lower end of upper end first section bar 2 of brace 9 links to each other through screw bolt and nut, and the lower end of brace 9 links to each other through screw bolt and nut with first section bar 2, and two extensions 8 on second connector 6 link to each other with the end of second section bar 1 with the 3rd section bar 4 respectively.Adopt connector and the bolt and nut section bar that is connected to form framework, compare welding manner in the past, easy to operate, low to workman's specification requirement, and practiced thrift electric energy greatly, reduced assembly cost.In order to gain in strength, first section bar, 2,3, the second section bars 1 that the utility model adopts and the shape of cross section of the 3rd section bar 4 all are " L " shape, and the shape of cross section of extension 8 also is " L " shape.
