Further, convenient mobile contact type voltage regulator body structure, also comprises master control knob, and described master control knob is through case lid.
Further, described case lid is provided with handle.So, during the utility model application, also can manually shift by holding handle, it is convenient in the time of further making the utility model application, to shift.
For fear of sedimentating dust in projection of the present utility model, further, the longitudinal section of described projection forms circular-arc.So, dust drops on the upper landing automatically of projection, the cleaning that keeps casing.
Further, the connecting portion of described case lid and casing forms rectangle frame shaped region to the edge of case lid, the inner vented cavity that forms connection box house of case lid, and the region of case lid formation rectangle frame shaped forms the ventilation hole of connecting extraneous and vented cavity.
Compared with prior art, the utlity model has following beneficial effect: on the sidewall of (1) casing of the present utility model left and right, all evagination formation has a plurality of projections, wherein, the bottom of projection forms to have connects box house and extraneous bar shaped ventilation breach, the utility model is different from prior art and directly adopts the mode of hollow out to carry out perforate, but by making after the sidewall evagination of casing the more protruding lower surface bar shaped ventilation breach at evagination, by bar shaped ventilation breach, carry out ventilation and heat, under the effect of blocking of projection, dust is difficult for directly falling in casing, can reduce and enter the dust in casing, improved the cleanliness factor in casing, and then can avoid piling up a large amount of dust in casing and affect the normal work of contact type voltage regulator box house part, guaranteed the pressure regulating performance of contact type voltage regulator, casing of the present utility model lower end is connected with a plurality of rollers, can adopt the mode of rolling to shift to the utility model, and it is convenient to shift.
(2) on casing front/rear end of the present utility model, be equipped with many support columns, wherein, support column upper end is flexibly connected with casing, the level height of support column lower end is lower than the level height of idler wheel bottom, so, under the positioning action of support column, can avoid roller arbitrarily to roll, and rotating support post make its lower end upward in the time need shifting the utility model, and then supported by pair of rollers casing, then by the mode of rolling, the utility model is shifted.
(3) connecting portion of case lid of the present utility model and casing to the edge of case lid forms rectangle frame shaped region, wherein, box house forms the vented cavity of connecting box house, the region that case lid forms rectangle frame shaped forms the ventilation hole that has the connection external world and vented cavity, so, during the utility model application, also can dispel the heat by the ventilating hole ventilation arranging on case lid, and then can improve radiating efficiency; The opening that on case lid, ventilation hole is connected an extraneous side is positioned at case lid bottom, and so, ventilation hole is also difficult for entering dust.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
In accompanying drawing, the corresponding name of Reference numeral is called: 1, casing, 2, case lid, 3, projection, 4, master control knob, 5, vernier knob, 6, display dial, 7, handle, 8, roller, 9, support column, 10, electric cabinet.
Embodiment
Below in conjunction with embodiment and accompanying drawing, the utility model is described in further detail, but execution mode of the present utility model is not limited to this.
