Description

A kind of rotary waterproof safety uncoupling power extension plate
Technical field
The utility model relates to a kind of power extension plate, especially relates to a kind of power extension plate of the rotary safe uncoupling plug that prevents to seep water.
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, all played not the water-tight effect, can cause inner each parts of socket moist; When energized, be easy to generate short circuit and initiation fire or electric shock accidents.In the prior art simultaneously, need certain strength when pulling the plug out of the socket, because the electrode pins of plug is longer; The stingy firmly plug in place, slit that often causes people to point between plug and socket pulls out outward; When the electrode pins some was exposed at outside the socket, electrode pins also was in the circuit turn-on, and the user is as because of carelessness; Very easy contacting on the electrode pins caused electric shock accidents.
Summary of the invention
The purpose of the utility model is to existing deficiency, provides a kind of simple in structure, can also can not cause short circuit by water leaking-in in the socket aperture, and plug does not need can break away from the power extension plate that connects with pulling to pull out.
The utility model solves the technical scheme that its technical problem adopted: a kind of rotary waterproof safety uncoupling power extension plate, comprise upper shell, lower house, socket unit, uncoupling device, 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 panel embeds on annular table circle suitable with it, and the socket unit top is provided with the uncoupling device, and the uncoupling device is made up of holding piece and supporting plate; Holding piece links to each other with locating piece through the pin of living; The contiguous block of holding piece fork top loose joint is connected with both sides, supporting plate lower surface chute, and the baffle plate of supporting plate one side protrusion is affixed on the adjacent chute in upper shell panel hole aperture mutually, and the jack on the supporting plate face is corresponding with the socket of socket unit; The socket of said socket unit is an in-line otch on the flexible silicon colloid; 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.
The chute width of said supporting plate lower surface chute inner chamber is greater than chute mouth width.
The chute width of said supporting plate lower surface chute inner chamber is greater than chute mouth width.
Said holding piece one end is provided with button, and the button upper end is positioned at the upper shell outside.
Said socket unit panel lower end 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.
The socket flexible silicon colloid of said socket unit is cylindric.
The in-line otch that the socket of the utility model socket unit becomes for the elastic silica gel system is not when plug is gone into socket, because the flexible silicon colloid is a column; Otch is dark; Otch seam fits together tightly, after plug inserts, and otch fit tightly owing to the be squeezed pin of plug; Completely cut off of the infiltration of extraneous moisture, played waterproof action to the power extension intralamellar part.When the pin 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; Even inserting in the socket, foreign matter can not cause electric shock accidents yet; After having only plug to insert the solid folder of electrode, the Rotating socket unit makes the rotating part rotation; 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.When pulling the plug out of the socket, need not to hold plug and carry out drawing; The tilting as long as pressing button, holding piece make progress, the interlock supporting plate holds up; Supporting plate ejects plug; Make plug base pin disengaging electrical connection and make open circuit, prevent that finger from contacting the pin exposed portions serve and causing electric shock accidents, improved the security performance of socket.The utility model advantage: simple in structure, low cost of manufacture, safe waterproof protection against electric shock performance is good.
