Together consult Fig. 3, support 31 can be tabular in certain embodiments, so that the articulated structure between first insulator 32 and second insulator 33 and the support 31 is on same plane.Support 31 comprises rectangular shaped rim 310; Be arranged to parallel interval first vertical pole 311, second vertical pole 312 and the 3rd vertical pole 313 in the rectangular shaped rim 310, and with first vertical pole 311, second vertical pole 312 and the 3rd vertical pole 313 cross bar 314 with frame 310 transversely strengthenings.The upper and lower that the upper and lower of first vertical pole 311 is formed with first interface 3110 and second interface, 3112, the three vertical poles 313 respectively is formed with first interface 3130 and second interface 3132 respectively. First interface 3110,3130 supplies two first bulbs 315 to be placed through wherein respectively, and second interface 3112,3132 supplies two the 3rd bulbs 316 to be placed through wherein respectively.
In certain embodiments, first interface 3110,3130 is a manhole, so that first bulb 315 is when being installed on wherein, and the position relative fixed.The quantity of second interface 3112,3132 is several and is ellipse or Long Circle through hole; These several second interface 3112,3132 is distributed on the length direction of first vertical pole 311 and the 3rd vertical pole 313 compartment of terrain respectively; So that the 3rd bulb 316 can be fixed in the second different interfaces 3112,3132 as required; From the adjusting of the upper-lower position of realizing lead fixed dish 34, and then realize of the adjusting of experiment lead 40 with respect to the position of cage body 20.
In addition,, after the 3rd bulb 316 is fixed in wherein, can also in second interface 3112,3132, move around easily, thereby realize fine setting the upper-lower position of lead fixed dish 34 owing to second interface, 3112,3132 ovalize or Long Circles.In certain embodiments, the length overall of the 3rd bulb 316 can be about 20 centimetres, and the band external thread, blocks in second interface 3112,3132 that can be fixed on support 31 with two nuts.Through the setting nut position, can reach the effect that experiment lead 40 and cage span leave in the fine setting cage body 20, the fine setting scope is between 0 ~ 3 centimetre.Be appreciated that ground, second interface 3112,3132 also can be other strip, can reach the fine setting effect equally.
As shown in Figure 4, lead fixed dish 34 in certain embodiments can be in the form of annular discs, and its diameter is about 90 centimetres, and can to adopt thickness be that 25 millimeters A3 steel plate is processed, and surface of steel plate is antirust through galvanizing.Lead fixed dish 34 can comprise a center through hole 343, four first slotted eyes 344, four second slotted eyes 345 and four the 3rd slotted eyes 346.Center through hole 343 can be used to fixing single experiment lead, with the simulation solid conductor; And first slotted eye 344, second slotted eye 345 and the 3rd slotted eye 346 can be used for fixing many experiment leads with the simulation multiple fission conductor; And can make the experiment lead in the slotted eye shift position; To regulate the spacing of many experiment leads, this spacing range can be 22 centimetres-78 centimetres in certain embodiments.
As shown in Figure 4 again, four first slotted eyes 344 all are strip, and along the radially extension of lead fixed dish 34, these four first slotted eyes 344 are rounded arrayed around the center of lead fixed dish 34.Four second slotted eyes 345 also are strip and along the radially extension of lead fixed dish 34; The length of second slotted eye 345 is less than the length of first slotted eye 344; Four second slotted eyes 345 are the rounded arrayed around the center of lead fixed dish 34 also; But with four first slotted eyes 344,45 degree that stagger, so, second slotted eye 345 can constitute the circular array of one eight slotted eye with first slotted eye 344.Four the 3rd slotted eyes 346 are strip and along the radially extension of lead fixed dish 34; Angle in these four the 3rd slotted eyes 346 and above-mentioned four first slotted eyes 344 between the straight line at two first slotted eyes on two relative positions 344 place is 60 degree, and constitutes the circular array of one six slotted eye with these two first slotted eyes 344.
From the above; Contain center through hole 343 in the lead fixed dish 34 and center on four slotted eye circular array, six slotted eye circular array and the eight slotted eye circular array that are formed centrally in the lead fixed dish 34; Be easy to realize to simulate the situation of single, 2 divisions, 3 divisions, 4 divisions, 6 divisions, 8 split conductors on it; And concrete wire pitch can be regulated, and should use very convenient quick.
Lead fixed dish 34 tops also are formed with two first interfaces 347; The bottom of lead fixed dish 34 also is formed with two second interfaces 348; These two first interfaces 347 are used to supply second bulb 341 to place, and these two second interfaces 348 are used to supply the 4th bulb 342 to place (as shown in Figure 2).Two first interfaces 347 and two second interfaces 348 are uniformly distributed in the periphery of lead fixed dish 34, so that lead fixed dish 34 can remain in the vertical plane under user mode basically.
As shown in Figure 1 again; In use; Two ends of several experiment leads 40 are separately fixed on the lead fixed dish 34 of two wire erection devices 30 of the two opposite sides that are positioned at cage body 20; And the lead fixed dish 34 of giving these two wire erection devices 30 provides first pulling force in opposite directions; Each lead fixed dish 34 also receives first insulator 32, second pulling force obliquely of corresponding lead stringer 30 this moment, the gravity of making a concerted effort to overcome lead fixed dish 34 of first pulling force and second pulling force, and lead fixed dish 34 is hanged.In addition, the existence of second insulator 33 makes lead fixed dish 34 under user mode, can remain on basically in the vertical plane.
The above only is the preferred implementation of the utility model, and the protection domain of the utility model also not only is confined to the foregoing description, and all technical schemes that belongs under the utility model thinking all belong to the protection domain of the utility model.Should be pointed out that for those skilled in the art in several improvement and the retouching that do not break away under the utility model principle prerequisite, these improvement and retouching also should be regarded as the protection domain of the utility model.
