Description

A kind of rotary waterproof safety power extension plate
Technical field
The utility model relates to a kind of power extension plate, especially relates to a kind of safety power supply expansion board of rotary waterproof.
Background technology
The power extension plate is the electric equipment products that are used for realizing through the insertion of external plug electrical connection in the daily life, and in use, people run into the environment that water is arranged through regular meeting, or because of carelessness water is sprinkled to the power extension plate the generation that causes the accident.So; The technical staff has developed the power extension plate with water-proof function; These waterproof power extension plates are equipped with waterproof cover outside socket, anti-sealing penetrates in the socket aperture, and some power extension plate is provided with sealing ring outside socket aperture; In the time of in the plug insertion socket hole, make between plug and the socket and play sealing function.In existing these technology, can't really reach the effect of waterproof, if do not build waterproof cover; Or plug and socket contact-making surface imprecision, water resistance has played not effect, all can cause inner each parts of socket moist; When energized, be easy to generate short circuit and initiation fire or electric shock accidents.
Summary of the invention
The purpose of the utility model is to existing deficiency, provides a kind of simple in structure, prevents to get an electric shock, and also can not cause the power extension plate of short circuit in the socket aperture behind the water leaking-in.
The utility model solves the technical scheme that its technical problem adopted: a kind of rotary waterproof safety power extension plate; Comprise upper shell, lower house, socket unit, said upper shell and lower house joint are provided with seal washer, and said upper shell panel is provided with the hole that at least one is used for the mounting receptacle unit; The hole sidewall is provided with annular table circle; Said socket unit cover plate embeds on annular table circle suitable with it, and said upper shell panel is provided with a chute adjacent with the hole mouth, is equipped with the baffle plate that socket unit cover plate one side is protruded on the chute; Said socket unit is provided with the socket of flexible silicon colloid otch; Below the socket unit socket, be provided with the rotating part of the solid folder of connection electrode, rotating part cooperates with Connection Block on the lower house through rotating shaft.
Said socket unit cover plate is equal with the upper shell panel, and the lower end of cover plate is provided with waterproof gasket.
The electrode that the solid folder of said electrode links to each other is struck the post and is passed rotating part and touch with the electrodes conduct sheet on rotation mode and the Connection Block and close, and the electrodes conduct sheet is with external wire and is electrically connected.
The flexible silicon colloid of said socket unit socket is cylindric, and the center is provided with the in-line otch.
Said socket unit is provided with the socket that live wire and zero line two inserted, or socket unit is provided with the socket that live wire, zero line and ground wire three are inserted.
The utility model upper shell and lower house composition surface are provided with sealing ring, and the in-line otch that the socket of socket unit becomes for the elastic silica gel system is not when plug inserts socket; Because the flexible silicon colloid is a column, otch is dark, and the otch seam fits together tightly; After plug inserts; Otch is fitted the electrode slice of plug tightly owing to be squeezed, completely cut off the infiltration of extraneous moisture to the power extension intralamellar part, has played waterproof action.When the electrode slice of plug is inserted into the solid folder of electrode, directly do not contact with the electrodes conduct sheet because the electrode of the solid folder of electrode is struck the post, the solid folder of electrode is not charged; Can not cause electric shock accidents even foreign matter inserts in the socket yet, have only plug to insert the solid folder of electrode after, the Rotating socket unit; Make rotating part rotation, the electrode in the solid folder of rotating part top electrode strike the post with Connection Block on the electrodes conduct sheet touch mutually and close, just make current lead-through; Improve the security performance of socket, prevented the generation of electric shock accidents.The utility model advantage: simple in structure, low cost of manufacture, safe water resistance is good.
