Embodiment

can be expressly understood the technical spirit and the beneficial effect of the utility model more for the auditor that the makes Patent Office especially public; The applicant general combines accompanying drawing to elaborate with the mode of embodiment below; But the description to embodiment all is not the restriction to the utility model technical scheme, any according to the utility model design done only for pro forma but not substantial equivalent transformation all should be regarded as the technical scheme category of the utility model.

see also Fig. 1, and a kind of sectional type switch cubicle housing comprises base plate 1, side plate 2, column 3 and cabinet door 4, adopt screw thread to interfix between described base plate 1, side plate 2, column 3, the cabinet door 4.The switch cubicle housing is used to hold inner electric elements, and above-mentioned base plate 1, side plate 2, column 3 and cabinet door 4 form the space of a relative closure.

are threaded to typically refer to and adopt cooperating or the cooperation of bolts and nuts of screw and nut, more and then, the fit system of part employing screw and nut, another part then adopts the fit system of bolts and nuts.Certainly adopt the similar part of above-mentioned screw, bolt, nut but its function equivalent also should belong to the scope that the utility model technical scheme is protected.

for example: at first base plate 1 is threaded with four root posts, 3 usefulness, with same thread connecting mode four blocks of side plates 2 is installed on the column 3, the last same mode that is threaded that adopts is installed on cabinet door 4 on the column 3.Location between above-mentioned detachable each parts of mounting means considered is reliable, to avoid occurring alignment error.

please continue to consult Fig. 1 and combine Fig. 2; The described column 3 of the utility model comprises rack body 31, first coupling assembly 32, second coupling assembly 33; Described first coupling assembly 32 is used for base plate 1 fixing, and described second coupling assembly 33 is used for cabinet door 4 fixing.Rack body 31 is a bullion spare, is formed by the sheet metal bending.First coupling assembly 32 is positioned at the end of rack body 31 near base plate 1 one sides, and second coupling assembly 33 is positioned at the end of rack body 31 near cabinet door 4 one sides.

first coupling assembly 32 comprises nested nut 322 and nested screw 323; Nested nut 322 is fixed in the chamber 34 that constitutes with rack body 31 ends; And contact with described chamber 34; Described nested screw 323 and nested nut 322 threaded engagement, and limit nested nut 322.Open Side Down in said chamber 34, and its upper end has the screw hole 3211 that is used for fixing, and described nested nut 322 is fixing with chamber 34 through hold-down screw 321, and screw 321 passes screw hole 3211.Fixing described nested nut 322 is the hollow cone nut, and its inboard offers screw thread, is used for cooperating with nested screw 323, and promptly nested screw 323 is provided with external screw thread, and the external screw thread on the nested screw 323 is corresponding with the internal thread on the nested nut 322.Nested nut 322 is positioned at 34 inside, chamber; And fit with one section sidewall in chamber 34; This kind fit structure makes nested nut 322 can balance the normal force in the certain angle, is convenient to it in lock chamber 321 inner stablizing, and has improved reliability of positioning and installation accuracy too.

When install ; Described base plate 1 is fixing up and down with base plate 1 with nested nut 322 through nested screw 323; Specifically: on base plate 1, offer installing hole 11, on nested screw 323, be provided with step 3231, the size of installing hole 11 matches with step 3231; And the base diameter of nested nut 322 is greater than the diameter of installing hole 11, thereby makes nested screw 323 and the nested nut 322 can be with base plate 1 clamping in the centre.Above-mentioned connection makes base plate 1, nested screw 323 and nested nut 322 become an integral body.After this, through with above-mentioned base plate 1, nested screw 323 and nested nut 322 as in overall fixed to the chamber 34, and be screwed, thereby accomplish the fixed installation of base plate 1 and cabinet post 3.

second coupling assembly 33 comprises a fixing hole 331; Corresponding with fixing hole 331, on cabinet door 4, be provided with cabinet aperture of door 41, above-mentioned fixing hole 331 cooperates with cabinet aperture of door 41; And with screw and nut matching and fixing, thereby cabinet door 4 is fixedly connected with cabinet post 3.

Support 5 is installed on a side of nested screw 323, is used for the installation of switch cubicle
