Embodiment
The invention will now be described in further detail with reference to the accompanying drawings.
Fig. 1 to Fig. 7 schematically shows the travelling power conversion plug extension according to one embodiment of the present invention.
As shown in Fig. 1~Fig. 7, the travelling power conversion plug extension is integrally in cylindrical, including four plug (English mark plugs
41st, American Standard plug 42, Europe superscript plug 43 and Australia's mark plug 44), and accommodate the shell 10 of plug.
The axially disposed external chute 11 for having an open at one end on the overall cylindrical shape of shell 10, shell 10.Each
It is both provided with extending to the operation pin 60 of outside on plug inside shell 10.Plug can along external chute 11 in active position and
Moved back and forth between inoperative position.Shell 10 is rotated relative to plug.Active position is being electrically connected with external power supply for plug
Position, inoperative position is the position inside plug retraction shell 10.
Rotational shell 10, makes the position of the operation pin 60 for the plug that the position alignment of external chute 11 needs to use, pulls behaviour
Making pin 60 makes operation pin 60 be moved along external chute 11, drives plug to be moved to active position, the inserted link of plug is stretched from shell.
When the inserted link of a plug stretches out shell 10, other plugs are kept off in inoperative position by the lateral edge of shell 10, are made
Inserted link cannot stretch out, and so both be easy to use, and security is also higher.
The inner casing 20 for accommodating plug is additionally provided with shell 10.It is axially disposed on inner casing 20 to have internal chute 23.Each
Plug is both provided with corresponding internal chute 23, and the length of internal chute 23 can be set according to the stroke of corresponding plug.Plug can
To be moved back and forth along corresponding internal chute 23 between live end 231 and invalid end 232.The live end 231 of internal chute 23 and invalid
The width at end 232 is more than the width in the stage casing of internal chute 23.Operation pin 60 extends to outer through internal chute 23 inside inner casing 20
Portion, operation pin 60 is connected by elastomeric element (not shown) with plug；Operation pin 60 rear portion is sequentially provided with neck 61 and stopper 62,
The width of neck 61 is less than the width in the stage casing of internal chute 23, and the width of stopper 62, which is more than the width in the stage casing of internal chute 23 and is less than, to be had
Imitate the width at end 231 and invalid end 232.
As shown in fig. 6, the position of the operation pin 60 of the plug needed to use when the position alignment of external chute 11, is pressed inward
Pin 60 is operated, the stopper 60 of operation pin 60 departs from the invalid end 232 of internal chute 23, then will operate pin 60 toward effectively along internal chute 23
End 231 is pulled, and plug is moved to active position.Operation pin 60 is unclamped, because operation pin 60 is by elastomeric element and plug
Connection, in the presence of elastomeric element, operation pin 60 is pushed up outward.Because the width of live end 231 and invalid end 232 is more than
The stage casing of internal chute 23, the stopper 62 of operation pin 60 is stuck in the live end of internal chute 23.This set makes plug in no external force
When acting on operation pin 60, active position or inoperative position can be stably positioned in, it is ensured that Electrical Safety.
