Abstract
The utility model discloses a safe dustproof plug board, comprising an insulating plug board body and a double-pole switch. The double-pole switch is connected with the live wire and the zero wire of a power supply; a rotary cover plate is arranged over the jacks of the plug board body; the cover plate is provided with hollowed-out holes with shapes consistent with the jacks; the hollowed-out holes form a certain angle with corresponding jacks; and the cover plate is provided with an arrowhead sign indicating a rotation direction. The double-pole switch controls the live wire and the zero wire of the power supply, when the double-pole switch is off, the live wire and the zero wire are broken simultaneously, no conducted wire exists in the jacks of the plug board after power is off, in an original state, the hollowed-out holes have a certain angle with the jacks, the jacks are shielded, dust and water are stopped outside, the safety is enhanced, the arrowhead sign indicating the rotation direction is provided on the cover plate, maloperation by a user is prevented, and the service life is raised. The design is ingenious, the plug board is safe and high-efficient, usage is convenient, and popularization is easy.
Description
Technical field
The utility model relates to a kind of electric power plug socket, particularly a kind of safe dustproof power extension socket.
Background technology
In recent years along with the rapid growth of Chinese national economy, living standards of the people improve constantly, and the people require also to promote to quality of life thereupon, and various household electrical appliance have by leaps and bounds been come into every family! The people wash in a pan liquor-saturated among happy life happy and harmoniously, present a slice scene of flourishing life everywhere! The growing growth of country, people's fundamental interests gets a promotion greatly, and negative effect also increases thereupon, and particularly child and misoperation, inserts conductive body and the electric shock accidents that produces happens occasionally.
One end of the single entry switch open-circuit line arranging on tradition insert row, most of office and domestic electric appliance are all the secondary side control appliance switches of transformer now, if the single entry switch pipe on tradition insert row is zero line, live wire causes faint electric discharge when nearer at device interior and earth connection line-spacing so, cause any property loss, especially through the old electric equipment of amateur maintenance and the circuit of amateur finishing.
Utility model content
The utility model object is to address the above problem, provide a kind of security performance good, easy to use, design careful safe dustproof power extension socket.
For achieving the above object, the technical scheme that the utility model adopts is: a kind of safe dustproof power extension socket, the insert row body and the double-pole switch that comprise insulation, described double-pole switch is connected with zero line with the live wire of power supply respectively, the jack top of described insert row body arranges rotating disc type overlay, the hollow hole of corresponding jack shape is set on described overlay, and described hollow hole and corresponding jack are at an angle.
Described overlay below arranges pin, and described pin connects tie point on described insert row by elastomer.
Described elastomer is arranged in the groove of described insert row body top, and described pin front end can move in described groove.
The arrow mark of rotation direction is set on described overlay.
The utility model is controlled described double-pole switch respectively live wire end and the zero line side of power supply, press double-pole switch, live wire and zero line disconnect simultaneously, prevent from still having a wire conducting in the jack of power-off back card/back board body, avoid connection device standby dry running, rotating disc type overlay is set above the jack of described insert row body, the hollow hole of corresponding jack shape is set on described overlay, described hollow hole and corresponding jack are at an angle, described in during initial condition, hollow hole and described jack are at an angle, described jack is blocked, both can prevent that dust and water from entering, avoid the power supply short circuit accident of therefore bringing, improved fail safe, further below described overlay, pin is set, described pin connects tie point on described insert row by elastomer, can realize on book and say that overlay restores to the original state automatically, improved the security performance of described electric power plug socket, and time saving and energy saving in use procedure, described elastomer is arranged in the groove of described insert row body top, described pin front end can move in described groove, operate steadily, avoid occurring uneven twisting and stop the phenomenon that gets stuck, the arrow mark of rotation direction is set on described overlay, being convenient to user is rotated according to the application of force direction of spring, avoid misoperation, improved the useful life of described insert row.The utility model design is ingenious, cost of investment is low, safe and efficient, easy to use, be convenient to generally promote the use of.
accompanying drawing explanation:
Below in conjunction with accompanying drawing, the utility model is further described:
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of the utility model overlay.
Embodiment
