The insulation performance electric property of electric elements insulating cylinder itself must be protected in line system.The shielding is exactly that insulating cylinder goes out
Important electrical equipment in factory's electrical test, fully firm, otherwise influence examination must be contacted with insulating cylinder by being shielded during experiment
Test the accuracy of result.Current shielding contact is not firm, dismounting is inconvenient.
Utility model content
For problems of the prior art, the utility model provides a kind of insulating cylinder electrical test shielding, installation
It is firm, it is convenient for disassembly and assembly.
The technical solution adopted by the utility model to solve its technical problems is that：
A kind of insulating cylinder electrical test shielding, including holder, the holder are connected separately with the first shielding in both sides up and down
Ring and secondary shielding ring, the holder between the first shading ring and secondary shielding ring are set as multiple, and shading ring is processed by aluminum pipe
It forms, bottom plate is equipped on the inside of secondary shielding ring, bottom plate is processed into circular weld by aluminium and is fixed on secondary shielding ring.The bottom
Centrosymmetric mounting hole there are two being set on plate, portion is equipped with the pedestal for connecting input voltage conductor in the soleplate.
Further, it is equipped with threaded hole on the upside of the insulating cylinder, fixing bolt is rotatably installed in threaded hole across mounting hole
It is interior.
Further, it is equipped with upper draw ring on the downside of first shading ring, lower draw ring, institute are equipped on the upside of the secondary shielding ring
It states draw ring with lower draw ring to be connected by the first spring, first spring outwards are equipped with holder, the upper end of the holder
Face is in contact with the first shading ring, secondary shielding ring respectively with lower face, and the holder is equipped with link block, on the link block
It is connected with sliding rail, sliding block is sliding combined on the sliding rail, consolidating for the arc for fixing insulating cylinder is installed on the sliding block
Fixed board is equipped with second spring between sliding block and link block.
Further, the fixed plate moves back and forth along mounting hole realization.
Further, the holder is process by aluminum pipe and is welded on the first shading ring and secondary shielding ring.
The utility model has the beneficial effects that：
The utility model is reasonable for structure, easy to use, and installation is simple, and adjustment surplus is big, shields the contact with insulating cylinder and fills
Point, it is completely embedded, it is fixed, the accuracy of test result is improved, solves problems of the prior art.
Description of the drawings
Fig. 1 is the front view of the utility model；
Fig. 2 is the vertical view of the utility model；
Fig. 3 is the use state diagram of the utility model；
Fig. 4 is the structural schematic diagram of the utility model second embodiment.
In figure：1 first shading ring, 2 secondary shielding rings, 3 holders, 4 bottom plates, 5 pedestals,
6 mounting holes, 7 fixing bolts, 8 insulating cylinders, 91 times draw rings, draw ring on 92,93 first springs, 94 link blocks, 95 slide
Rail, 96 sliding blocks, 97 fixed plates.
Specific implementation mode
As shown in Figure 1 to Figure 3, a kind of insulating cylinder electrical test shielding includes a holder 3, and the holder up and down divide by both sides
It is not connected with the first shading ring 1 and secondary shielding ring 2, the holder between the first shading ring and secondary shielding ring could be provided as
It is multiple.And shading ring is process by aluminum pipe.Holder can be process by aluminum pipe and be welded on the first shading ring and secondary shielding
On ring.
Bottom plate 3 is equipped on the inside of secondary shielding ring, bottom plate can be processed into circular weld by aluminium and is fixed on secondary shielding ring.
Centrosymmetric mounting hole 6 there are two being set on the bottom plate, portion is equipped with pedestal 5 in the soleplate, and pedestal is for connecting input voltage
Conductor.
As shown in figure 3,8 upside of insulating cylinder is equipped with threaded hole, fixing bolt 7 is rotatably installed in threaded hole across mounting hole 6
It is interior.Insulating cylinder is firmly secured to by shielding downside by fixing bolt in this way.
If you need to handle the insulating cylinder of different-diameter, then need to prepare multiple and different shieldings to be installed, it is time-consuming to take
Power, cost are also relatively high.
It is illustrated in figure 4 the structural schematic diagram of second embodiment.Upper draw ring 92 is equipped on the downside of first shading ring, it is described
Lower draw ring 91 is equipped on the upside of secondary shielding ring, the upper draw ring is connected with lower draw ring by the first spring 93, first bullet
93 outside of spring is equipped with holder 3, and the upper surface of the holder 3 connects with the first shading ring, secondary shielding ring respectively with lower face
It touches.
The holder is equipped with link block 94, is connected with sliding rail 95 on the link block, is sliding combined on the sliding rail
Sliding block 96 is equipped with the fixed plate 97 of the arc for fixing insulating cylinder on the sliding block.It is equipped between sliding block and link block
Second spring 97.
Optimization design, the fixed plate can be realized along mounting hole to be moved back and forth.
It is the known technology of those skilled in the art in addition to the technical characteristic described in specification.
