Detailed description of the invention
Below in conjunction with accompanying drawing, this utility model is described in further detail.
This specific embodiment is only to explanation of the present utility model; it is not to restriction of the present utility model; the present embodiment can be made after reading this specification by those skilled in the art as required does not has the amendment of creative contribution, but as long as all being protected by Patent Law in right of the present utility model.
The electric instrument of high-tension switch cabinet, as it is shown in figure 1, it includes meter body 1 and fixed mechanism 2.Meter body 1 includes fore shell 13 and back cover 14, and back cover 14 is connected two-by-two by four blocks of side plates 11 and is spliced.The surrounding outwardly convex 15 of fore shell 13 is the most spacing and be exposed on high-tension switch cabinet secondary chamber door-plate.
Having intersection 12 everywhere, intersection 12 on back cover 14 is all the arcwall face processed through rounding.Fixed mechanism 2 has four to be separately positioned on the intersection 12 that side plate 11 is connected with side plate 11, is connected fixing to meter body 1 and high-tension switch cabinet secondary chamber door-plate.As in figure 2 it is shown, fixed mechanism 2 includes the arcuate guide portion 21 slided along intersection 12 arcwall face and is separately positioned on the fixed part 22 of arcuate guide portion 21 both sides.Arcuate guide portion 21 is a block-shaped spigot surface consistent with arcwall face.Two fixed parts 22 are integrally manufactured with arcuate guide portion 21 to be formed.Each fixed part 22 include joint face 24 and the end from joint face 24 be inclined upwardly extend fixed strip 25.Joint face 24 is connected on each self-corresponding side plate 11 respectively；Being provided with slide block 4 on the lower surface of every piece of joint face 24, slide block 4 is positioned at the chute 5 being opened on side plate 11, and fixed mechanism 2 is slided along chute 5 by slide block 4.Each fixed mechanism 2 has two fixed strips 25, and fixed strip 25 is combined with joint face 24 and is formed with inclination angle, and the angle at this inclination angle is at 5-30 degree.This inclination angle processes through rounding；Avoid stress concentration on this inclination angle, cause fixed strip 25 to rupture.Having a space between fixed strip 25 and joint face 24, this space is as the relief area 26 of compensator or trimmer pressure.When electric instrument or high-voltage switch gear are by external force, mutually extruding between fixed strip 25 and door-plate, the be squeezed effect of power of fixed strip 25 deforms to relief area 26；Fixed strip 25 decomposes the active force to fixed mechanism 2 by deformation simultaneously；Avoid it excessive impaired because of stress.
Connecting in arcuate guide portion 21 has engaging portion 23, fixed mechanism 2 to be fixed with fastener snapping on arcwall face by engaging portion 23 with meter body 1.Offering one domatic 13 on arcwall face, fastener is helical rack 3, and some helical racks 3 are arranged on domatic 13.Engaging portion 23 includes the contiguous block 27 being fixed on arcuate guide portion 21 and from the downward-sloping extension in the end of contiguous block 27 fastener 28 being bent up being converted into " v " type, and the bottom of fastener 28 is provided with helical rack 3.The incline direction of the helical rack 3 on domatic 13 is the most contrary with helical rack 3 incline direction on fastener 28, and both can be interlocked.The fastener 28 of engaging portion 23 is arranged to the benefit of " v " type structure: fastener 28 has the position being folded upward at, it is easy to finger stretch into engaging portion 23 upwards to lift and disengage it from, disconnect and the connection of helical rack 3, then fixed mechanism 2 is exited along the wall of intersection 12.
During installation, fixed mechanism 2 is entered along chute 5 by slide block 4, and the helical rack 3 bottom fastener 28 is engaged with helical rack 3 phase on side plate 11 intersection 12 domatic 13, it is achieved fixed mechanism 2 and the snapping of meter body 1；Having the fixed mechanism 2 of perpendicular type on four angles of meter body 1, the left and right two ends of every block of side plate 11 have fixed strip 25 to fix；With the monolateral fixed structure of the opposite sides plate 11 of prior art, the intensity of Corner Strapped structure of the present utility model is better, stability is more increased.During dismounting, only need to disengage it from the position that is folded upward at of finger jack-up fastener 28, disconnect and the connection of domatic 13 helical racks 3, just can easily fixed mechanism 2 be exited；Whole unloading process is the most convenient.
This utility model fixed mechanism 2 and meter body 1, in addition to the connected mode being mutually twisted by helical rack 3, also have another kind of fixing connected mode: save the helical rack 3 in engaging portion 23 and domatic 13；On the inwall of arcuate guide portion 21, directly offer an installing hole, spring and dop be set in installing hole, dop be shaped as hemispherical.The hole clipping coordinated with dop is offered on domatic 13.Fixed mechanism 2 is achieved a fixed connection with hole clipping clamping by dop with meter body 1.During dismounting, arcuate guide portion 21 is exerted a force, make the position of dop indentation installing hole removal hole clipping, disconnect and just can realize dismounting.
