As shown in fig. 1 and 2, the embodiment of the present disclosure provides an insulator 70 fixture, which insulator 70 fixture includes a clasping ring 10, a pressing member 20, and a connecting post 30.

Specifically, the clasping ring 10 is used for connection with the insulator 70; the pressing piece 20 is arranged above the embracing ring 10, and a clamping area for clamping the overhead cable 60 is formed between the pressing piece and the embracing ring 10; the connecting column 30 is arranged between the embracing ring 10 and the compressing piece 20 along the first direction, and one end, far away from the embracing ring 10, of the connecting column 30 penetrates through the compressing piece 20, so that the compressing piece 20 can slide on the connecting column 30 to achieve adjustment of the clamping area.

For example, the connection manner of the clasping ring 10 and the insulator 70 may be a structure of the clasping ring 10 in the prior art and clamped on the insulator 70, and only the clasping ring 10 is required to be mounted on the insulator 70, which is not limited in particular.

Here, it should be noted that the above-mentioned "above" may refer to an upper region of the band 10, and may refer to a front side or a rear side of the pressing member 20 above the band 10, for example: the compressing element 20 is located on the front side above the embracing ring 10, and the rear side portion of the compressing element 20 can still compress the cable 60 located in the clamping area, at this time, the position of the compressing element 20 can be regarded as being located above the embracing ring 10; for example, the pressing member 20 is located at the rear side above the clasping ring 10, and the front side portion of the pressing member 20 can still press the cable 60 located in the clamping area, and the location of the pressing member 20 can be regarded as being located above the clasping ring 10, which is not particularly limited. In this embodiment, preferably, the compressing member 20 is located directly above the clasping ring 10, so that the compressing member 20 can compress the cable 60 to the greatest extent, and the effect of clamping caused by sliding of the cable 60 is avoided.

Illustratively, the two ends of the pressing member 20 are provided with the through holes 22, and the connecting post 30 passes through the through holes 22, so that the pressing member 20 can slide on the connecting post 30, and the size of the clamping area can be adjusted according to the cables 60 with different sizes, so that the clamping device is suitable for the cables 60 with different sizes. In addition, when the pressing member 20 is adjusted to a position where the cable 60 is pressed, a locking member (for example, a nut) is required to be disposed at one end of the connecting post 30 penetrating the pressing member 20, and the pressing member 20 is locked by the locking member, so as to prevent shaking during use and influence the clamping effect.

For example, the holding ring 10, the pressing member 20 and the connecting post 30 may be made of metal or non-metal, which is not limited thereto, but the strength of the material used is required to be ensured to be certain, so that the cable 60 cannot be clamped due to poor strength in the use process can be avoided. The materials of preparation can be further selected according to different regional environments, for example, if the regional environments are often provided with corrosive substances, the holding ring 10, the compressing piece 20 and the connecting post 30 can be made of corrosion-resistant composite materials.

The specific usage method of the insulator 70 fixture of this embodiment is as follows:

fixedly connecting the holding ring 10 to the insulator 70, arranging the pressing piece 20 above the holding ring 10 by using the connecting column 30, positioning the cable 60 to be aerial in a clamping area (an area between the pressing piece 20 and the holding ring 10), and then pressing the pressing piece 20 towards a direction close to the holding ring 10 so as to enable the pressing piece 20 to slide on the connecting column 30, and further changing the clamping area to press the cable 60, thereby completing the installation of the insulator 70 clamp; when the insulator 70 clamp is required to be disassembled, the insulator clamp can be disassembled only by disassembling the pressing piece 20 in the direction away from the holding ring 10 and then disassembling the holding ring 10 from the insulator 70.

The insulator 70 clamp based on the technical characteristics is characterized in that the clamp ring 10 is used for fixing the insulator 70, then the pressing piece 20 is arranged above the clamp ring 10 through the connecting column 30, and the pressing piece 20 can slide on the connecting column 30, so that the size of a clamping area is adjusted, cables 60 with different sizes can be clamped, and the universality is improved; meanwhile, the insulator 70 clamp is simple in structure and convenient to install, standardized operation is achieved, construction quality is guaranteed, and working efficiency and reliability of a power grid line are effectively improved.

As shown in fig. 3, in one embodiment, the clasping ring 10 includes a first ring body 11 and a second ring body 12, and a clasping opening 13 for clasping the insulator 70 is defined between the first ring body 11 and the second ring body 12. Thus, the connection with the insulator 70 can be realized, and the structure is simple, and the disassembly and the assembly are convenient.

As shown in fig. 3, in one embodiment, at least one first mounting hole 11d is formed at both ends of the first ring body 11, at least one second mounting hole 12a is formed at both ends of the second ring body 12, and the connection post 30 passes through the aligned first mounting hole 11d and the second mounting hole 12a. In the case where the first mounting hole 11d is selected to be aligned with a different second mounting hole 12a, the size of the clasping opening 13 can be changed accordingly.

Here, the term "at least one" means one or more than one, and the specific number of settings is required according to the actual situation. For example: if the insulator 70 is used only for the same batch, only one first mounting hole 11d and one second mounting hole 12a may be provided, the first mounting hole 11d on the first ring body 11 and the second mounting hole 12a on the second ring body 12 are aligned, and then the connecting post 30 is used to sequentially pass through the first mounting hole 11d and the second mounting hole 12a, so as to implement cohesion on the insulator 70; if the insulators 70 of different batches need to be used, a plurality of (for example, two or three) first mounting holes 11d and second mounting holes 12a need to be provided, and according to the insulators 70 of different diameters, the first mounting holes 11d are selectively aligned with the second mounting holes 12a of different diameters, so as to realize corresponding adjustment of the clasping openings 13, and satisfy clasping of the insulators 70 of different diameters.

In addition, the arrangement of the first step groove 11e and the second step groove can limit the adjusting positions of the ground connection portion and the second connection portion 11c, and prevent the first connection portion 11b or the second connection portion 11c from being separated and not being capable of realizing cohesion.

In this embodiment, the protecting cover 40 can effectively protect the compressing member 20, the connecting post 30 and the holding ring 10 from unnecessary damage. In addition, the fastening space formed by the arc edge 40a and the protecting cover 40 is utilized to fasten the pressing piece 20, so that the protecting cover 40 can be detachably connected with the pressing piece 20, and the protecting cover 40 can be conveniently detached later. The arrangement of the shield 40 may be determined according to the actual situation, and the shield 40 may be removed if it is not required.

In one embodiment, a grip 50 is provided on the surface of the shield 40 facing away from the band 10.
