Description
Technical field
The present invention relates to the technical field of power supply plug-in unit, specifically is convenient transfer plug.
Background technology
Along with the development of modern society, increasing electric equipment products enter into popular life, and the running of electrical equipment all be unable to do without power supply usually, and plug is as the necessary tool of connecting circuit and power supply, and its application technology is also improving constantly.For now, the socket supporting with plug generally has two sockets and three sockets, therefore, the plug corresponding with socket also is divided into two-pin plug and three-pin plug, as application number is that 200520146156.7 Chinese utility model patent discloses horizontal bipod attaching plug, it has solved existing vertical bipod attaching plug effectively and has easily come off, and big technical problem takes up room.It comprises two conduction latches, the plug body that the last insulation cover plate of relative socket surface and following insulation cover plate are formed, or be injection molded into all-in-one-piece plug body, it is characterized by: the corner of its wire outlet around plug body.And for example application number is that 200420047833.5 Chinese utility model patent discloses the cloudy socket three-pin plug of convex, comprise ground, fire, the cloudy socket of three metals of zero line, be located in three socket apertures 3 of the header body 2 that insulating material constitutes, derive lead-in wire from described socket aperture rear end, the cross section of described header body is a convex shape hierarchic structure; Described socket aperture 3 is arranged as one on top, and bead 1 is established in the header body rear end in left and right each one of bottom, makes with pottery.Though two above-mentioned patents have been made improvement to two-pin plug and three-pin plug respectively, but still there is the problem that two-pin plug and three-pin plug can not be general, be that two-pin plug only can be applicable to two sockets, and three-pin plug also only can be applicable to three sockets, therefore, bother very much in use, the problem that incidental socket of electrical equipment that frequent appearance is bought and indoor socket do not match, perhaps be suitable in a place, but more inapplicable problem behind the adjourn at this moment, often needs to buy wiring board, not only sink money, and use also inconvenient.
Summary of the invention
Technical problem to be solved by this invention is the present situation at prior art, a kind of novel and reasonable structure, compact conformation is provided, can realizes the transfer plug that two-pin plug and three-pin plug are freely changed.
The present invention solves the problems of the technologies described above the technical scheme that is adopted: convenient transfer plug, comprise base and be installed on L utmost point conduction inserted sheet, N utmost point conduction inserted sheet and ground connection conduction inserted sheet on the base, it is characterized in that: L utmost point conduction inserted sheet passes with the bottom correspondence of N utmost point conduction inserted sheet and fixedlys connected first column spinner and second column spinner, and the bottom of first column spinner and second column spinner is all rotated and is inserted on the base; Ground connection conduction inserted sheet is connected with the 3rd column spinner, the first-class radian of the 3rd column spinner perisporium offers the opening that matches with ground connection conduction inserted sheet, the bottom of ground connection conduction inserted sheet is arranged in the opening and through rotational positioning pin and the 3rd column spinner and is hinged, and the lower end apical grafting of ground connection conduction inserted sheet has the ground connection brace that is fixed in the 3rd column spinner.
In order to obtain better technique effect, further technical measures also comprise:
The middle part of the first above-mentioned column spinner, second column spinner and the 3rd column spinner all is shaped on boss, the bottom surface of the downside apical grafting base of boss.
Wherein a kind of more excellent scheme is: the first above-mentioned column spinner, second column spinner and the 3rd column spinner all are the gears that are shaped on tooth on the outer peripheral face of boss; The 3rd column spinner is meshed with second column spinner, and second column spinner is meshed with first column spinner simultaneously.
The number of teeth that is meshed with the 3rd column spinner on the second above-mentioned column spinner is more than the number of teeth that is meshed with first column spinner on second column spinner.
Another kind of more excellent scheme is: the first above-mentioned column spinner, second column spinner and the 3rd column spinner all are the gears that are shaped on tooth on the outer peripheral face of boss; The 3rd column spinner is meshed with first column spinner, and first column spinner is meshed with second column spinner simultaneously.
The number of teeth that is meshed with the 3rd column spinner on the first above-mentioned column spinner is more than the number of teeth that is meshed with second column spinner on first column spinner.
Above-mentioned base is provided with first reference column that matches with first column spinner and second reference column that matches with second column spinner.
Above-mentioned base is provided with the gear fixed head, have on the gear fixed head three respectively with L utmost point conduction inserted sheet, N utmost point conduction inserted sheet and the suitable through hole of ground connection conduction inserted sheet, L utmost point conduction inserted sheet, N utmost point conduction inserted sheet and ground connection conduction inserted sheet pass through hole; Have on the gear fixed head and the suitable notch of the ground connection of inversion state conduction inserted sheet, notch is communicated with ground connection and conducts electricity the through hole that inserted sheet matches.
Compared with prior art, L utmost point conduction inserted sheet bottom embedding hoop of the present invention is on first column spinner, and described N utmost point conduction inserted sheet bottom embedding hoop is on second column spinner; The bottom of first column spinner and second column spinner is all rotated and is inserted on the base; The first-class radian of the 3rd column spinner perisporium offers the opening that matches with ground connection conduction inserted sheet, the bottom of ground connection conduction inserted sheet is arranged in the opening and through rotational positioning pin and the 3rd column spinner and is hinged, and the lower end apical grafting of ground connection conduction inserted sheet has the ground connection brace that is fixed in the 3rd column spinner.Because first column spinner, second column spinner can rotate, therefore, L utmost point conduction inserted sheet and N utmost point conduction inserted sheet can be changed between three-pin plug and two-pin plug two states; And ground connection conduction inserted sheet and the 3rd column spinner are hinged, therefore can topple over and erect around the rotational positioning pin, when needs during from the tripod state exchange to the bipod state, ground connection is conducted electricity inserted sheet to be fallen and promptly can not hinder L utmost point conduction inserted sheet and N utmost point conduction inserted sheet to insert in the socket, when needs during, ground connection is conducted electricity inserted sheet erect and get final product from the bipod state exchange to the tripod state.
