Utility model content
The purpose of this utility model is that it is big can to adjust internal diameter in view of the above problems, provide a kind of transformer high-voltage bushing
It is small, it is easy to use.
In order to achieve the above object, the technical solution adopted in the utility model is：It includes the outer tube and inner tube of U-shaped, described
Inner tube open end is stretched into outer tube, and said inner tube outer wall is contacted with outer tube wall, and setting is spaced on said inner tube opening side end face
There is blind hole, spring is provided in the blind hole, the spring is contacted with adjustment column, and the adjustment column activity interts and stretches out blind
Hole, the adjustment column are respectively arranged with Internal baffle and outer baffle on outer tube, the adjustment column in outer tube inner side and outer side, institute
It states and is provided with threaded block on outer tube blind end, be to be provided with tapped blind hole in threaded block, the tapped blind hole internal thread is connected with
Threaded post, the threaded post end are stretched out threaded block and are fixedly connected with swivel head, and the swivel head is contacted with adjustment column.
Further, limiting plate is provided in the adjustment column, the limiting plate is connect with spring；The blind hole inner wall is set
It is equipped with the only side extended to internal diameter.
Further, empire cloth is connected between the inner wall of said inner tube both sides, the empire cloth stage casing is set in outer tube
On wall.
Further, the outer baffle is adapted with outer tube outer wall, and the Internal baffle is adapted with outer tube wall.
The beneficial effects of the utility model：Rotate swivel head so that threaded post stretches into tapped blind hole, and swivel head is to outer tube
Movement, adjustment column is pressed by swivel head so that and adjustment column stretches into blind hole, under the promotion of outer baffle, outer tube and inner tube institute
The spatial area enclosed reduces；Rotate swivel head so that threaded post to tapped blind hole movement outside, swivel head far from outer tube,
By the elastic force of spring, swivel head is far from outer tube, and under the promotion of Internal baffle, the spatial area that outer tube and inner tube are enclosed increases
Greatly；Pass through, the spatial area transformation that outer tube and inner tube are enclosed, the cable to meet plurality of specifications passes through.
It 1, being capable of the space that is enclosed of sealed outer pipe and inner tube by empire cloth, it is ensured that safe to use.
