Easily pull out safety socket
Technical field
The present invention relates to electric power facility field, especially, relate to a kind of power receptacle.
Background technology
Socket is power infrastructures, is the power taking interface of terminal power consumption equipment; Current power receptacle all adopts direct insertion structure, after namely the plug of electrical appliance stretches into jack, directly with in socket, the metal spring leaf that is connected zero live wire contacts; In order to make plug difficult drop-off, must make to closely cooperate between plug and reed; But, just due to closely cooperating between plug and reed, in plug plug process, usually need to take larger strength, especially in the process pulling out plug, in order to avoid plug cord is pulled bad, usually need stingy tight plug body just can pull out plug, and when plug base pin is partly pulled through the pipe, finger in fastening shape is easy to encounter pin by mistake, now, because pin is still in electrical contact with zero live wire, so very likely cause electric shock accidents; As can be seen here, current socket, not only extremely requires great effort in the process pulling out plug, and very dangerous.
Summary of the invention
For the problems referred to above, the object of the present invention is to provide one easily to pull out safety socket, this socket is extremely easy to pull out plug, has higher fail safe.
The technical solution adopted for the present invention to solve the technical problems is: this easily pulls out safety socket and comprises base shell, and the panel of described base shell has at least one pair of jack, and described jack inside is provided with connector; Correspond to each to described jack in described base shell, be respectively equipped with a U-tube road, described panel is vertically run through from the line center of a pair jack corresponding to this U-tube road in the one end in described U-tube road, and the other end in described U-tube road runs through described panel from the grafting areas outside of a pair jack corresponding to this U-tube road; Two ends Feng Youyi the piston respectively in described U-tube road, two pistons are respectively to outer connection piston rod; Time in jack without plug, when the piston rod of wherein submerges described U-tube road completely, another root piston rod stretches out U-tube road completely under the internal pressure effect of U-tube road.
As preferably, under the state that two described pistons are not all subject to external pressure, in described U-tube road, seal the air having 1 standard atmospheric pressure.
As preferably, seal in described U-tube road and have hydraulic oil.
As preferably, the piston rod being in described grafting areas outside is shaped with pressure cap, is beneficial to pressing.
Beneficial effect of the present invention is: when this easily pulls out safety socket use, during to pull out the plug be plugged in jack, only need press the described piston rod of jack grafting areas outside, U-tube road internal pressure then residing for this piston rod increases, impel the piston rod being in two jack line central authorities outwards to eject U-tube road, thus in the center of plug outside ejection plug, make plug very easily be pushed out jack, and without the need to touching plug body with hand, there is higher fail safe.

Embodiment
Below in conjunction with drawings and Examples, the present invention is further described:
In the embodiment shown in Fig. 1, Fig. 2, this easily pulls out safety socket and comprises base shell 1, the panel 11 of described base shell 1 has a pair jack 10,10 ', described jack 10,10 ' inside be provided with connector 12,12 '; This is corresponded to jack 10,10 ' in described base shell 1, be provided with a U-tube road 2, the one end in described U-tube road 2 from this to jack 10,10 ' line center vertically run through described panel 11, the other end in described U-tube road runs through described panel 11 from this to the grafting areas outside of jack 10,10 '; Two ends Feng Youyi the piston 31,32 respectively in described U-tube road 2, two pistons are respectively to outer connection piston rod 311,321; As shown in Figure 1, jack 10,10 ' middle without plug time, when the piston rod of wherein 311 submerges described U-tube road 2 completely, another root piston rod 32 stretches out U-tube road completely under U-tube road 2 internal pressure effect.
Above-mentioned socket, described two pistons 31,32 are not all by under the state of external pressure, and in described U-tube road 2, envelope has the air of 1 standard atmospheric pressure; This can guarantee without under plug inserting state, and the piston rod 311 being in jack grafting region can submerge U-tube road 2 completely.Certainly, when cost allows, also hydraulic oil can be sealed up for safekeeping in described U-tube road 2.
In the present embodiment, the piston rod 321 being in described grafting areas outside is shaped with pressure cap 322, is beneficial to pressing.
Above-mentioned easily pull out safety socket use time, to pull out be plugged on jack 10,10 ' in plug time, only need press the described piston rod 321 of jack grafting areas outside, then this U-tube road 2 internal pressure residing for piston rod 321 increases, impel be in two jacks 10,10 ' piston rod 311 of line central authorities outwards ejects U-tube road 2, thus in the center of plug outside ejection plug, make plug very easily be pushed out jack, and without the need to touching plug body with hand, there is higher fail safe.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
