Directly, second adjusting rod is connect by elongated hole with closed fixture.
Preferred embodiment, the adjusting nut are wing nut.
Preferred embodiment, first adjusting rod and the second adjusting rod are stainless steel screw rod.
The junction of preferred embodiment, the mounting plate and semi-ring connected in star is equipped with stiffener plate.
The utility model compared with prior art, has the following advantages and benefits: one kind of the utility model is more
The universal bottle-holding rack of large-tonnage strain insulator is changed, this bottle-holding rack is lifted insulator chain when replacing insulator, torn open
When unloading and installing insulator, insulator bottle-holding rack can provide good support for insulator, avoid operating personnel high aerial
Manually crawl insulator carries out operation, greatly alleviates the manual labor of operating personnel, improves replacing insulator efficiency.Together
When this bottle-holding rack the distance between two shafts of bracket and two shafts and enclosed can be adjusted according to the outer diameter of insulator
The distance between card, to lift the insulator of different model, improves the versatility used and flexibility of this bottle-holding rack.This axis
Bar uses epoxy resin insulation material, which has light weight, and intensity is high, good insulating, makees convenient for electrification and high-altitude
Industry.
Detailed description of the invention

Specific embodiment
For the purpose of this utility model, technical solution and advantage is more clearly understood, below with reference to embodiment and attached drawing,
The utility model is described in further detail, and the exemplary embodiment and its explanation of the utility model are only used for explaining this
Utility model is not intended to limit the scope of the present invention.
Embodiment
As shown in Figure 1, a kind of universal bottle-holding rack of replacement large-tonnage strain insulator of the utility model, including supports insulative
The bracket of sub- bottom is connected separately with closed fixture at the both ends of bracket, which includes two and be parallel to each other and spaced
Shaft 1, shaft 1 are cylindrical epoxy resins insulation stick.The first tune for adjusting 1 spacing of shaft is connected between two shafts 1
Pole 2, there are two the first adjusting rod 2 is set, two the first adjusting rods 2 are connected to the both ends of two shafts 1.At the both ends of shaft 1
It is respectively equipped with the second adjusting rod 3 connecting with closed fixture, there are four the second adjusting rod 3 is set, four the second adjusting rods 3 are respectively perpendicular
It is mounted on the both ends of two shafts 1.First adjusting rod 2 and the second adjusting rod 3 are stainless steel screw rod, in the first adjusting rod 2 and the
Adjusting nut is connected on two adjusting rods 3, adjusting nut is preferably wing nut.The rotating adjusting nut on the first adjusting rod 2
Spacing between two shafts 1 is adjusted, suitable for not having to the insulator of diameter, spacing is between two shafts 1 to be less than insulator
Outer diameter be advisable;By on the second adjusting rod 3 rotating adjusting nut come adjust two shafts 1 between closed fixture at a distance from,
The spacing of two shafts 1 and closed fixture with the outer circle of insulator with two shafts 1 are tangent is advisable.
Closed fixture includes pedestal 4 and semi-annular cover plates 5, and the middle part of pedestal 4 is equipped with semi-ring connected in star, and the two of semi-ring connected in star
Side is connected with mounting plate, and the junction of mounting plate and semi-ring connected in star is equipped with stiffener plate, offers elongated hole on a mounting board,
