Abstract
The invention provides an extensible insulator which comprises a plurality of ceramic sleeves, wherein each ceramic sleeve is provided with a hollow channel, two ends of each ceramic sleeve are respectively provided with an upper end pipe and a lower end pipe, the upper end pipe is provided with an upper channel, the lower end pipe is provided with a lower channel, the upper channel and the lower channel are respectively communicated with two ends of the hollow channel, an elastic rubber ring is arranged in the upper channel and is attached to the inner wall of the upper end pipe, the lower end pipe is inserted into the elastic rubber ring in the upper end pipe of the adjacent ceramic sleeve, and an umbrella skirt structure is arranged outside each ceramic sleeve; this kind of can prolong formula insulator sets up upper end pipe and lower extreme pipe through the tip at ceramic sleeving to can realize that length is adjustable through the grafting of adjacent ceramic sleeving's upper end pipe and lower extreme pipe, can satisfy multiple user demand. This kind of can prolong formula insulator, structural design is reasonable, can realize that length is adjustable, and it is convenient to adjust, and the cost is lower, does benefit to the use.
Description
Technical Field
The invention relates to an extensible insulator.
Background
The insulator is used for supporting and fixing the bus bar and the live conductor and ensuring that the live conductor or the conductor has enough distance and insulation with the ground. Insulators are used to increase the creepage distance and are usually made of glass or ceramic. The length of the existing insulator is fixed at present, the insulator can only be suitable for one length requirement, multiple applications can not be realized, and only single use requirements can be met.
The above-mentioned problems are problems that should be considered and solved in the design process of the insulator.
Disclosure of Invention
The invention aims to provide an extensible insulator which solves the problems that the length of the insulator in the prior art is fixed, the insulator can only be suitable for one length requirement, multiple applications cannot be realized, and only single use requirements can be met.
The technical solution of the invention is as follows:
the utility model provides a can prolong formula insulator, includes a plurality of ceramic sleeving, every ceramic sleeving is equipped with the cavity passageway, every ceramic sleeving's both ends are equipped with upper tube and lower extreme pipe respectively, the upper tube is equipped with the passageway, the lower extreme pipe is equipped with the lower passageway, the both ends of cavity passageway are communicate respectively with the lower passageway to the upper channel, be equipped with the elastic rubber ring in the upper channel, and the elastic rubber ring pastes the inner wall at the upper tube, in the lower extreme pipe inserts the elastic rubber ring in the upper tube of adjacent ceramic sleeving, the ceramic sleeving is equipped with the full skirt structure outward.
Furthermore, the inner wall of the upper end pipe is provided with a plurality of strip-shaped grooves, the adjacent strip-shaped grooves are arranged in parallel, and the strip-shaped grooves are arranged in parallel with the axis of the upper end pipe.
Furthermore, the elastic rubber ring is provided with a strip-shaped convex rib opposite to the strip-shaped groove.
Furthermore, the umbrella skirt structure adopts a structure that large umbrella groups and small umbrella skirts are alternated.
Furthermore, the umbrella skirt structure is made of ceramic or silicon rubber.
The invention has the beneficial effects that: this kind of can prolong formula insulator sets up upper end pipe and lower extreme pipe through the tip at ceramic sleeving to can realize that length is adjustable through the grafting of adjacent ceramic sleeving's upper end pipe and lower extreme pipe, can satisfy multiple user demand. This kind of can prolong formula insulator, structural design is reasonable, can realize that length is adjustable, and it is convenient to adjust, and the cost is lower, does benefit to the use.
Drawings
Fig. 1 is a schematic structural view of an extendable insulator according to an embodiment of the present invention;
wherein: 1-ceramic sleeve, 2-hollow channel, 3-upper end tube, 4-lower end tube, 5-elastic rubber ring, 6-umbrella skirt structure.
Detailed Description
Preferred embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
Examples
The utility model provides a can prolong formula insulator, including a plurality of ceramic bushing 1, every ceramic bushing 1 is equipped with cavity passageway 2, every ceramic bushing 1's both ends are equipped with upper end pipe 3 and lower extreme pipe 4 respectively, upper end pipe 3 is equipped with the passageway, lower extreme pipe 4 is equipped with the lower passageway, the both ends of going up passageway and lower passageway intercommunication cavity passageway 2 respectively, upward be equipped with elastic rubber ring 5 in the passageway, and elastic rubber ring 5 pastes the inner wall at upper end pipe 3, lower extreme pipe 4 inserts in the elastic rubber ring 5 in adjacent ceramic bushing 1's upper end pipe 3, ceramic bushing 1 is equipped with umbrella skirt structure 6 outward.
This kind of can prolong formula insulator sets up upper end pipe 3 and lower extreme pipe 4 through the tip at ceramic bushing 1 to can peg graft through upper end pipe 3 and lower extreme pipe 4 of adjacent ceramic bushing 1, realize that length is adjustable, can satisfy multiple user demand. This kind of can prolong formula insulator, structural design is reasonable, can realize that length is adjustable, and it is convenient to adjust, and the cost is lower, does benefit to the use.
The inner wall of the upper end pipe 3 is provided with a plurality of strip-shaped grooves, the adjacent strip-shaped grooves are arranged in parallel, and the strip-shaped grooves are arranged in parallel with the axis of the upper end pipe 3. The elastic rubber ring 5 is provided with a strip-shaped convex edge opposite to the strip-shaped groove. Through the setting of corresponding of bar groove and bar bead, can increase elastic rubber ring 5's stability, ensure elastic rubber ring 5's location.
The umbrella skirt structure 6 adopts a structure that a large umbrella group and a small umbrella skirt are alternated. The umbrella skirt structure 6 is made of ceramic or silicon rubber and is an umbrella skirt structure 6. The umbrella skirt structure 6 made of silicon rubber can reduce the overall weight of the insulator.
