Abstract

The utility model relates to a tripolar power plug adapter, which consists of a pulling device and which is has the function of pulling. The pulling mechanism consists of an upward prizing plate and an upward pulling plate. The utility model has the function of a socket for a prizing plug and a pressing plug. The utility model settles the problem that pulling of a tripolar plug or adapter sold in the prior market costs great efforts, and is inconvenient and unsafe.

Description

Power supply three-terminal polarized plus plug adapter with the function of pulling out

Technical field: the utility model relates to a kind of power supply three-terminal polarized plus plug adapter that is made of driver-extractor.

Background technology: attaching plug or the adapter sold on the existing market, rise and pull out effort, on the other hand according to socket, another hand unplugg of exerting oneself, the socket that will be fixed on the wall is stirred sometimes, can injure the person if any careless or electric leakage, to the elderly, the disabled person is more inconvenient especially.

Summary of the invention: the purpose of this utility model provides a kind of power supply three-terminal polarized plus plug adapter with the function of pulling out, and solves existing three-terminal polarized plus plug or adapter and works effort, the dangerous and not convenient problem of pulling out.

For achieving the above object, the utility model, power supply three-terminal polarized plus plug adapter with the function of pulling out, form by upper prying plate, upper lifting plate, axle and spring, on the upper lifting plate supporting plate of this adapter, be manufactured with plug pole piece guide rail and socket device by GB GB1002-80 specification requirement, the utility model feature is: by axle and spring upper prying plate and upper lifting plate are coupled together the clip shape structure that is constituted, the front end of upper prying plate has three A, B, C ripping bar, A, C are the both sides across supporting plate, and B is inserted in the rectangular groove of baseplane of supporting plate.

Adopted such structure, after this adapter inserted supply socket, upper prying plate and upper lifting plate had constituted rising to pull out and pinching pressure F of clip ₁, F ₂The active force lever, common clip lever is straight shape, and two active force levers of the utility model: upper prying plate and upper lifting plate are squares, on the vertical socket planar section be called respectively sled pull plate and on carry and pull plate, on the parallel socket planar section be called upper prying plate main body and upper lifting plate supporting plate respectively, be called for short supporting plate.When will rising when pulling out, with the thumb of hand and forefinger firmly one pinch sled pull plate and on carry and pull plate, act on and prize the power F that pulls on the plate ₁, the supporting plate rear is produced goes up sled power.Act on and carry the power F that pulls plate ₂Make on the supporting plate and carry, be produced on the plug pole piece of carrying adapter on the supporting plate and from supply socket, extract under in last sled power and upper lifting force, acting on.Compare with adapter with existing three-terminal polarized plus plug, the utlity model has drawing mechanism thereby rise pull out laborsaving, safe, easy to use.

Description of drawings: Fig. 1 is the upper prying plate component diagram, and Fig. 2 is the upper lifting plate component diagram, and Fig. 3 is the utility model clip shape driver-extractor structure chart.Fig. 4 is the power supply three-terminal polarized plus plug adapter outline drawing with the function of pulling out.

Embodiment: the utility model clip shape structure and operation principle are described in further detail below in conjunction with the drawings and specific embodiments.

Fig. 1 is a upper prying plate, and main body 1 front end has A, B, three ripping bars of C, and last sled is pulled plate 2 and is fixed by bolts on the main body 1.Pedestal 3 is bearing supports of axle 4.Axle 4 is another individual part, and drawing is signal axle 4 and the relative vertically-arranged in pedestal 3 assembling backs herein.Fig. 2 is a upper lifting plate, supporting plate 5 and on carry that to pull plate 6 are disjunctors, and vertical mutually.Pedestal 7 also is the bearing support of axle 4.Three through holes 8 are the holes of passing of plug or adapter pin pole piece.Spring 9 also is individual part, draw be signal spring 9 herein with pedestal 7 assemblings after relative position.

As shown in Figure 3: axle 4 passes the pedestal 3 of upper prying plate, and the pedestal 7 of upper lifting plate and the mesopore of spring 9 couple together upper prying plate and upper lifting plate, and a complete three-terminal polarized plus plug driver-extractor just is assembled.

On upper lifting plate supporting plate 5, be manufactured with plug, socket device, and after being inserted into supply socket, how finished the work of pulling out at driver-extractor?

The front end of upper prying plate shown in Figure 3 has three A, B, C ripping bar, A, C are the both sides across the supporting plate 5 of upper lifting plate, B is inserted in the rectangular groove of baseplane of supporting plate 5, the positive reaction force lever 10 of (A-A analyses and observe) spring 9 acts on respectively on the last plane of pulling plate 6 and upper prying plate main body, do not have external force F1, when F2 adds, under the effect of the positive reaction force of spring, the baseplane of the baseplane of upper prying plate main body and upper lifting plate supporting plate 5 is on same plane.When will rising when pulling out, with the thumb of hand and forefinger firmly one pinch sled pull plate 2 and on carry and pull plate 6, generation external force F ₁, F ₂, F ₁Power passes to three ripping bars of A, B on the upper prying plate main body, C, and A, B, C ripping bar produce the power of pressing down to the socket below the plug, and according to socket, the B ripping bar produces upper lifting plate supporting plate rear and goes up sled power, F simultaneously ₂Power makes on the upper lifting plate supporting plate 5 and carries.Be produced on pin pole piece on the supporting plate 5 in last sled power and upper lifting force, act under and from socket, extract.

Want to produce a kind of function of pulling out power supply three-terminal polarized plus plug adapter that had, as long as specification requirement by GB GB1002-80, plug pole piece guide rail and socket device are produced on the last plane of this driver-extractor upper lifting plate supporting plate 5, just constitute a power supply three-terminal polarized plus plug adapter with the function of pulling out.Using such method also can be produced the three-terminal polarized plus plug with the function of pulling out.

Claims

1. power supply three-terminal polarized plus plug adapter with the function of pulling out, upper lifting plate supporting plate (5) at this adapter upward is manufactured with plug pole piece guide rail and socket device by GB GB1002-80 specification requirement, the utility model feature is, by axle (4) and spring (9) upper prying plate and upper lifting plate are coupled together the clip shape structure that is constituted, the front end of upper prying plate has three A, B, C ripping bar, A, C are the both sides across supporting plate (5), and B is inserted in the rectangular groove of baseplane of supporting plate (5).
