Abstract
The utility model discloses a two-pole socket structure with a protective door. A protective door mechanism comprises the protective door which is formed by folding the same member correspondingly, wherein a base pin bracket with a base pin through hole is connected under the protective door, and rotary mechanisms which are matched with each other are arranged at the bottom of the protective door and the upper part of the base pin bracket; the protective door is formed in the way that two same members are matched with a circular hole by circular shafts arranged on the two same members, and the two same members are matched with a restoring spring to be assembled together. When a single pole is inserted into the two-pole socket structure, the protective door can not be opened. When the two poles are inserted in the two-pole socket structure, the restoring spring is extruded by the thrust force to make the two members of the protective door separated from eat other, and the base pin can be inserted. The protective door structure not only can be used in a two-oblate socket with a small space, but also can be widely applied to other sockets with two base pins. Thereby, the utility model improves the safety of the socket in the using process.

Existing safety socket with electroshock-proof function adopts the structure of shutter more, and the structure of shutter is divided built-in shutter and two kinds of structures of external shutter.China's ZL96107072.2 patent " safety socket " discloses a kind of fail safe socket, comprises parts compositions such as socket panel, roof door, push rod, push rod spring, conducting strip, support, stand spring, contact, binding post, connector and housing.It designs between binding post and connector one " switch ", this switch is by push rod that is provided with in the housing of socket and roof door, cooperate the support driven and on the conducting strip change in displacement realize its break-make, promptly by with the fine motion of the pin insert action interlock of plug or contact switch with connector and power connection.This structure will be passed through the UNICOM that push rod roof door interlock sensitive switch could be realized plug and socket; though can reach the purpose of safeguard protection; but set up link gear; make the structure relative complex; the switch cost increases greatly, and along with the increasing of access times, and accurately being difficult to of link gear guarantees; thereby have influence on the action of sensitive switch, also can reduce the useful life of switch.
The utility model content
Technical problem to be solved in the utility model provides a kind of simple in structure, safe the two poles of the earth socket.
The utility model is achieved through the following technical solutions:
Design a kind of the two poles of the earth socket, comprise socket surface lid and bottom seat, cover is provided with pin holes, is provided with binding post in the base, is provided with shutter mechanism between cover and base.Shutter mechanism comprises the shutter that identical components is combined to form, and is connected with the pin bracket of pin through hole under the shutter, and the shutter bottom is provided with the rotating mechanism that cooperatively interacts with pin bracket top.
Described two-phase cooperates butt joint with member by the axis hole that is provided with on the adjacent surface, is provided with the door shape groove of projection in the middle of the member bottom, is provided with bowst girder between the grooved pin bracket two pin through holes, and door shape groove and bowst girder form the matched in clearance structure.The pin through hole is corresponding with pin holes size on the cover in the pin bracket.
The middle part of each member is a vertical plane, the vertical plane both sides are set to the inclined-plane, vertical plane one side is provided with the circular shaft of protrusion on one side, another side is provided with and the circular hole that can match with the circular shaft of another member with the circular shaft antimere, the vertical plane outside is provided with circular shrinkage hole, be provided with boss in the shrinkage pool, the shrinkage pool boss is provided with back-moving spring.
Shutter is fixed in the cover by back-moving spring, and bottom, described cover two sides is provided with spring secures rail to sleeper, and chassis outer side is provided with the lock buckling groove that matches with spring secures rail to sleeper.
The utility model has following remarkable result compared with prior art:
The socket protective door mechanism of installing in two pole sockets provided by the utility model; self-locking structure is reliable; delicate structure; be directly installed in the socket surface lid; this shutter structure not only can be applied in the two oblate sockets in little space; also can promote the use of in the socket of other two utmost points pin configuration, improve the fail safe of socket use.

Fig. 2 is the structural representation of shutter 2 among Fig. 1;
Fig. 3 is the structural representation that shutter cooperates with pin bracket.
Embodiment
The utility model is described in further detail by embodiment below in conjunction with accompanying drawing.
A kind of the two poles of the earth socket; comprise socket cover 1 and base 5; cover is provided with pin holes; be provided with binding post 4 in the base; between cover and base, be provided with shutter mechanism; shutter mechanism comprises the shutter 2 that identical components is combined to form, and is connected with the pin bracket 3 of pin through hole under the shutter, and the shutter bottom is provided with the rotating mechanism that cooperatively interacts with pin bracket top.
The socket protective door comprises two identical members 21; the member middle part is a vertical plane; the vertical plane both sides are set to inclined-plane 26; vertical plane one side is provided with the circular shaft 22 of protrusion on one side; another side is provided with and the circular hole 23 that can match with the circular shaft of another member with the circular shaft antimere; the vertical plane outside is provided with circular shrinkage hole 24, is provided with boss 241 in the shrinkage pool, and boss is used to locate the back-moving spring of installing in the shrinkage pool 25.
Two members cooperate butt joint by circular shaft with circular hole after, the inclined-plane on two member both sides cooperates formation V-arrangement face 261.The socket protective door is connected between two walls of socket cover by the back-moving spring 25 that is provided with in the outside shrinkage pool 24 by member.
