Embodiment
As shown in figure 1, the company that the utility model includes insulation board 3 and one end is fixedly connected with one end of the insulation board 3
Fitting 2, the other end of the insulation board 3 are provided with the link 4 for connecting tension-resistant porcelain bottle wire, the connector 2 it is another
End is provided with hook 1, and the hook 1 includes being used for the hook part 1-2 for connecting cross-arm and the rotation with the connector 2 rotation connection
Transfer part 1-1, the rotating part 1-1 are fixedly connected with the hook part 1-2, and the other end of the connector 2 is provided with for preventing
The limited block 2-1 that only the rotating part 1-1 rotates to the opening direction of the hook part 1-2.
During actual use, hung over by hook 1 on cross-arm, turnbuckle or fixing-line device are connected by link 4, by tension-resistant porcelain bottle
The load transfer of carrying is on replacing instrument, so as to install new tension-resistant porcelain bottle, it is not necessary to workmen frequently in cross-arm and
Shift position between tension-resistant porcelain bottle wire.
As shown in Figure 1, Figure 2 and Figure 4, in the present embodiment, it is provided with the rotating part 1-1 for the another of the connector 2
The rotating gravure 1-4 that one end penetrates, the other end globoidal structure spherical in shape of the connector 2, the limited block 2-1 be provided with
The cambered surface that the surface configuration of connector 2 matches.
During actual use, limited block 2-1 is arranged on the openend of hook 1, and limited block 2-1 vertical section is that a line is arc
The triangle of shape, and arc matches with the surface configuration of connector 2.Hook 1 and connector 2 are rotatablely connected by bearing pin,
Due to the other end of connector 2 globoidal structure spherical in shape, hook 1 can without hindrance rotation up and down by axle of bearing pin.By even
The other end of fitting 2 sets limited block 2-1, because limited block 2-1 is to the support force of hook 1, the gravity of hook 1 can be overcome to make
With so that hook 1 can not rotate to the opening direction of hook 1 under gravity, it is achieved that the spacing work(to hook 1
Can, the opening direction of hook 1 is ensure that, so that hook 1 is easily hung on cross-arm.
As shown in figures 1 and 3, in the present embodiment, two hangers 4-1, two hangers 4- are provided with the link 4
1 one end with the insulation board 3 is rotatablely connected.
During actual use, the rotation connection of link 4 and insulation board 3 is realized by hangers 4-1, when link 4 carries strain insulator porcelain
During bottle wire tension, because extraneous stressing conditions are complicated, therefore link 4 rotates with the difference of extraneous stress, prevent due to
The direction of tension-resistant porcelain bottle wire tension and the direction of cross-arm pulling force are not on one wire so that instrument force unbalance is changed, from
And phenomena such as causing replacing instrument to be damaged.
Shown in Fig. 4, in the present embodiment, in addition to be opened in the hook part 1-2 ends screwed hole 1-3 and with the spiral shell
Pit 1-3 coordinates and for fixing the screw of the cross-arm.
During actual use, when hook 1 hang on cross-arm after, can by hook 1 inner side tightening screw method, from
And cross-arm is fixed on hook 1, prevent that the situation that extraneous factor causes cross-arm to be slipped from hook 1 from occurring, security is good, can
By property height.
Shown in Fig. 2, in the present embodiment, the connector 2 is cross connecting piece.
During actual use, insulation board 3 is connected to the both ends of connector 2 with hook 1, and insulation board 3 and connector 2 pass through
Screw is fastenedly connected, and hook 1 and connector 2 are rotatablely connected by bearing pin.
In the present embodiment, the connector 2 and limited block 2-1 are structure as a whole.
It is suspended on when it is implemented, workmen stands in tension-resistant porcelain bottle side of wire, insulation board 3 hand-held first by linking up with 1
On cross-arm, due to limited block 2-1 effect so that hook 1 can not rotate to the opening direction of hook 1, ensure that opening for hook 1
Mouth direction, so that hook 1 is easily hung on cross-arm, then passes through link 4, and be fastenedly connected by tension-resistant porcelain bottle wire
On link 4, link 4 rotates with the difference of extraneous stress, prevents due to the direction of tension-resistant porcelain bottle wire tension and cross-arm drawing
The direction of power is not on one wire so that instrument force unbalance is changed, phenomena such as so as to cause replacing instrument to be damaged.Peace
After the completion of dress, tension-resistant porcelain bottle wire is tensed by turnbuckle, by originally by the load transfer that tension-resistant porcelain bottle carries to replacing instrument
On, because hook 1 is rotatablely connected with connector 2, therefore in the presence of load pulling force, hook 1 and cross-arm in vertical state, from
And increase grasping force of the replacing instrument to cross-arm.Then the tension-resistant porcelain bottle more renewed, after installation, workmen is from link 4
On pull down tension-resistant porcelain bottle wire, then hold insulation board 3 and unloaded linking up with 1 from cross-arm, dismantlement work is in tension-resistant porcelain bottle wire
Side can complete, it is not necessary to the workmen frequently shift position between cross-arm and tension-resistant porcelain bottle wire, both alleviate work
Intensity, the potential safety hazard of short circuit is prevented again.
It is described above, only it is embodiment of the present utility model, not the utility model is imposed any restrictions, it is every according to this
Any simple modification, change and the equivalent structure change that utility model technical spirit is made to above example, still fall within
In the protection domain of technical solutions of the utility model.
