Background technology
At present, indoor power supply device is mostly socket.There are many kinds of sockets, including the metope being fixed on indoor wall
Socket.At present, application is more widely five hole wall jacks, as shown in Figure 1, the five holes wall jack is suitable for including one group
The two poles of the earth jack of the round plug of the two poles of the earth flat plug or the two poles of the earth and one group of three pole jack for being suitable for three pole flat plugs.Jack
The sleeve of the built-in inserted sheet grafting on plug, sleeve are connected with corresponding zero curve, firewire or ground wire.It it should be evident that should
Five spring hole scokets can only at most be inserted into a three-terminal polarized plus plug and a two-wire plug simultaneously, remaining after three pole jacks are occupied
The two poles of the earth jack can not be inserted into three-terminal polarized plus plug, and after the two poles of the earth jack is occupied, remaining three pole jack can not be inserted into the two poles of the earth plug.
With society and scientific and technological progress, miscellaneous electric equipment products are used more and more in production and life, such as：
Refrigerator, TV, washing machine, desktop computer etc..With increasing for electric equipment products, in daily life, often there are following situations：
The attaching plug for treating the electric appliance of electricity consumption is three pole flat plugs, but only one group two surplus on five spring hole scokets near the electrical appliance
Pole jack causes three pole flat plugs that can not be inserted on five spring hole scoket, goes on five spring hole scokets of distant place with can only seeking something far and wide when it is within reach
Find three pole jacks；Or treat that the attaching plug of the electric appliance of electricity consumption is the two poles of the earth plug, but five holes near the electrical appliance are inserted
One group of three pole jack is only remained on seat, causes the two poles of the earth plug that can not be inserted on five spring hole scoket, goes to distant place with can only seeking something far and wide when it is within reach
The two poles of the earth jack is found on five spring hole scokets；Above-mentioned two situations, it is very common in daily life, expose the use of five spring hole scoket
The defects of inconvenient.
Therefore, how to provide a kind of for electric installation so that it is extremely slotting that this supplies any one group of jack of electric installation that can be inserted into three
Head can be inserted into the two poles of the earth plug again, can avoid the defects of above-mentioned, improve the ease of use for electric installation, be current this field skill
The technical issues of art personnel's urgent need to resolve.

One bronze medal bearing, the second bronze medal bearing and third copper bearing so that level-one rotation housing can around Step Shaft longitudinal center line from
By rotating, so as to drive the three pole plugging hole component rotations formed comprising two rotary jacks and an earth polar jack, and protect
Door be integrally fixed on pedestal, be stationary, and set in protection door it is jagged so that level-one rotation housing rotation
During turning, two rotary jacks on partition board and an earth polar jack are turned under the non-barbed portion in protection door in the middle
Fang Shi can cause two on middle partition board rotary jacks to be blocked with an earth polar jack, and the inserted sheet of attaching plug can not be inserted into,
The object for the small volume that other foreign matter or children are held can not be also inserted into, so as to avoid the generation of children from getting electric shock phenomenon,
When two rotary jacks on partition board and an earth polar jack turn to the lower section of the barbed portion in protection door in the middle, it can cause
Two rotary jacks on middle partition board are exposed with an earth polar jack, and the inserted sheet of attaching plug can be smoothly inserted into, and are continued real
Now supply the function of supplying power of electric installation.

Tail is connected to form a triangle, the perpendicular bisector of the triangle is then done through each intersection point, the intersection point of three perpendicular bisectors is B
Point；It explains herein, in view of the seldom polarity column type plug of domestic appliance plug, and mostly it is the two poles of the earth flat plug, therefore the present invention
The jack that flat type inserted sheet 25 is for insertion into for the earth polar jack 6 on electric installation and rotary jack 7 of offer, opening are one
A rectangle；
Self-locking body 15 in the monopole plugging hole component is set to the inside of the two level rotation housing 14 and is set to institute
On the inner surface for stating the upper wall surface of two level rotation housing 14, and spaced apart the top for being located at the sleeve 17, it is described
Self-locking body 15 includes self-locking plate 1501 and fixed plate 1502, and the self-locking plate 1501 is separated by a certain distance composition with fixed plate 1502
One for being oriented to the space of self-locking inserted sheet 25, the self-locking plate 1501 and on long broad side surface close to the fixed plate 1502
There are one the inclined-plane for being used for self-locking, the two sides friendships of the extended surface on the inclined-plane and the long broad side surface of the inserted sheet 25 being inserted into for tool
Line passes through the width direction of the inserted sheet 25, the spacing between the inclined-plane and the long broad side surface of the corresponding inserted sheet 25
Gradually increase from top to bottom, the minimum spacing between the inclined-plane and the long broad side surface of the corresponding inserted sheet 25 are less than described
Maximum spacing between the long broad side surface of the diameter of self-lock rod 16, the inclined-plane and the corresponding inserted sheet 25 be more than it is described from
The diameter of locking bar 16；Herein, by above-mentioned inclined-plane, self-lock rod 16 and be inserted into after inserted sheet 25 in itself come realize inserted sheet 25 from
Lock function after inserted sheet 25 is inserted into sleeve 17, lifts, due to self-lock rod 16 by promoting unlock rod 10, and then by solution lock ring 9
Axial both ends are overlapped in the open slot 903 of solution lock ring 9, at this point, self-lock rod 16 can rise with the rising of solution lock ring 9, and
It is finally clamped between inclined-plane and the long broad side surface of inserted sheet 25, so as to fulfill auto-lock function, prevents inserted sheet 25 unintentional non-artificial
Ground is pulled from above-mentioned jack；If not promoting unlock rod 10, when inserted sheet 25 moves upwards under external force, can drive certainly
Locking bar 16 rises together so that self-lock rod 16 is finally clamped between inclined-plane and the long broad side surface of inserted sheet 25, so as to fulfill self-locking
Function prevents inserted sheet 25 is unintentional from being pulled from above-mentioned jack non-artificially；When needing to extract inserted sheet 25 from above-mentioned jack
When, being unlocked by pressing bar 10 first promotes to solve lock ring 9 and moves down, since the axial both ends of self-lock rod 16 are overlapped on the opening of solution lock ring 9
In slot 903, at this point, self-lock rod 16 can moving down and move down, and finally destroy above-mentioned gripping orientation with solution lock ring 9, so as to
It realizes unlocking function, successfully extracts inserted sheet 25；Above-mentioned self-locking body 15, self-lock rod 16, solution lock ring 9 and unlock rod 10 are
Electrically insulating plastic material part；
