Technical field
The present invention relates to insulator cap technical field, more particularly to a kind of water proof and dust proof insulator cap.
Background technology
For current practical disc insulator, whether common porcelain or nature of glass dish-type insulator or compound
Suspension insulator, the connection member between its insulator is mainly chapeau de fer and the steel pin that coordinates with it, this part are normalized
Use always.
The content of the invention
Based on technical problem existing for background technology, the present invention proposes a kind of water proof and dust proof insulator cap.
A kind of water proof and dust proof insulator cap proposed by the present invention, including：Lower cap, upper cap, bar portion and umbrella portion；
To be inverted barrel-like structure, upper cap is arranged on lower cap lower cap, is cavity inside upper cap, and its top offers rod aperture,
The notch for connecting its inner chamber and rod aperture is offered on upper cap, the boundary of notch and upper cap leg is up-narrow and down-wide horn shape；
Bar portion is up-narrow and down-wide horn shape, and is matched with notch；Bar portion is provided with external screw thread, and external screw thread is apart from bar portion
The distance of bottom is less than the depth of upper cap inner chamber；Perforation is provided with the middle part of umbrella portion, the internal thread matched with external screw thread is provided with perforation.
Preferably, in addition to limiting plate, limiting plate is arranged on lower cap and in upper cap inner chamber by spring, spring and
Limiting plate is that conducting metal is made.
Preferably, upper cap is fillet structure.
Preferably, lower cap is fillet structure.
Preferably, the upper cap of umbrella portion covering.
Preferably, bar portion bottom is oval calotte, and limiting plate is provided with the groove matched with bar portion bottom.
In the present invention, bar portion can be inserted into upper cap by notch, and the top of bar portion is stretched out from rod aperture；Then, in upper cap
It is interior to move up bar portion, it can prevent bar portion from deviating from from notch.Umbrella portion and bar portion can be connected through a screw thread, and bar portion is being inserted to cap
Afterwards, it is assembled into by umbrella portion in bar portion, one, can be spacing to bar portion progress by umbrella portion, avoid bar portion from moving down；Two, it can lead to
Cross umbrella portion to block rod aperture, avoid rainwater dust etc. from being polluted by rod aperture into upper cap.
Brief description of the drawings
Fig. 1 is a kind of water proof and dust proof insulator cap structural representation proposed by the present invention；
Fig. 2 is upper cap and lower cap schematic diagram；
Fig. 3 is upper cap top view；
Fig. 4 is bar portion schematic diagram.
Embodiment
Reference picture 1, a kind of water proof and dust proof insulator cap proposed by the present invention, including：Lower cap 1, upper cap 2, bar portion 3 and umbrella
Portion 4.
Reference picture 2, Fig. 3, lower cap 1 are inversion barrel-like structure.Upper cap 2 is arranged on lower cap 1, and the upper inside of cap 2 is cavity, its
Top offers rod aperture 21.The notch 22 for connecting its inner chamber and rod aperture 21, notch 22 and the upper leg of cap 2 are offered on upper cap 2
Have a common boundary for up-narrow and down-wide horn shape.Reference picture 4, bar portion 3 is up-narrow and down-wide horn shape, and is matched with notch 22.Such as
This, bar portion 3 can be inserted in upper cap 2 by notch 22, and the top of bar portion 3 is stretched out from rod aperture 21；Then, by bar in upper cap 2
Portion 3 moves up, and can prevent bar portion 3 from deviating from from notch 22.Similarly, the diameter of the bottom of bar portion 3 is set greater than the straight of rod aperture 21
Footpath, can be to prevent bar portion 3 from deviating from from rod aperture 21.
In present embodiment, limiting plate 5 is installed in upper cap 2, limiting plate 5 is arranged on lower cap 1 by spring 6, spring 6
Under normality, limiting plate 5 rises support and multiplies bar portion 3 so that bar portion 3 moves up；Limiting plate 5 is pushed, bar portion can be dismounted by notch 22
3.In present embodiment, the bottom of bar portion 3 is oval calotte, and limiting plate 5 is provided with the groove matched with the bottom of bar portion 3.
In present embodiment, bar portion 3 is provided with external screw thread 31, and distance of the external screw thread 31 apart from the bottom of bar portion 3 is less than upper cap 2
The depth of inner chamber.The middle part of umbrella portion 4 is provided with perforation, is provided with the internal thread matched with external screw thread in perforation, the diameter in umbrella portion 4 is more than bar
The diameter in hole 21.In this way, umbrella portion 4 and bar portion 3 can be connected through a screw thread, after bar portion 3 is inserted into cap 2, assembled by umbrella portion 4
Onto bar portion 3, one, bar portion 3 can be carried out by umbrella portion 4 spacing, avoid bar portion 3 from moving down；Two, can be by umbrella portion 4 to bar
Hole is blocked, and avoids rainwater dust etc. from being polluted by rod aperture 21 into upper cap 2.Specifically, the upper cap 2 of the covering of umbrella portion 4, with
Notch 22 is protected.In present embodiment, spring 6 and limiting plate 5 are that conducting metal is made.
In present embodiment, upper cap 2 is fillet structure, to avoid wedge angle from endangering.Similarly, lower cap 1 is fillet structure.
The foregoing is only a preferred embodiment of the present invention, but protection scope of the present invention be not limited thereto,
Any one skilled in the art the invention discloses technical scope in, technique according to the invention scheme and its
Inventive concept is subject to equivalent substitution or change, should all be included within the scope of the present invention.
