Description

Folding conversion power plug

Technical Field

The utility model relates to a power plug, concretely relates to can be at two holes and three foldable power plug of hole socket free conversion.

Background

The standards of different countries are different, and the plugs and the sockets used are different, so that the problem that the plugs and the sockets are not matched when the electric appliances are used is frequently encountered in daily life. The plug and socket commonly used by people are divided into two-pin (hole) and three-pin (hole), and usually the two-pin plug is matched with the two-hole socket, and the three-pin plug is matched with the three-hole socket. However, in life, only a three-hole socket is used when a two-pin plug is used, or only a two-hole socket is used when a three-pin plug is used. In this regard, two pin plugs have been invented with pins that are angularly rotatable to accommodate use with only three-pin receptacles. At present, a safety socket is popularized and used in a large quantity, three jacks of the socket are all shielded by separation blades, and when a plug pin is inserted into a third hole corresponding to a ground wire, the separation blades of the other two jacks can be opened simultaneously. Variable angle two-prong plugs are also not available for use with such sockets. Furthermore, almost all current three-prong plugs cannot directly use a two-hole socket. This brings inconvenience to the temporary use of the electric appliances in our daily life and work.

Disclosure of Invention

The utility model discloses the technical problem that will solve is: in view of the above problems, a folding conversion power plug usable with both a two-hole outlet and a three-hole outlet is provided.

The technical solution of the utility model is that: folding conversion power plug, participate in including casing and two variable angles, two variable angles are participated in and are fixed in the casing and can change the angle of self in order to adapt to the angle of waiting to insert the socket hole through gear connection, still include a collapsible participating in that corresponds the ground wire, collapsible participating in includes grafting section and axle linkage section, and grafting section and axle linkage section are L shape and link together, the casing is opened respectively on preceding terminal surface and the upper and lower face adjacent with preceding terminal surface and is used for accomodating the groove of accomodating of collapsible participating in, and collapsible participating in rotationally connects through a minor axis in axle linkage section the groove department of accomodating of casing for collapsible participating in its grafting section corresponds the jack of ground wire with three hole sockets when opening corresponding, folding the participating in of folding can accomodate in the groove.

The technical effects of the utility model are that: the socket has the advantages of simple structure, reasonable design and convenient use, and can be freely converted and used between two-hole or three-hole sockets.

Detailed Description

As shown in fig. 1, 2 and 3, the folding conversion power plug comprises a housing 1 and two variable angle pins 2, wherein the two variable angle pins 2 are fixed in the housing 1 and connected through a gear 3 to change the angle of the pins to adapt to the angle of the socket holes to be inserted, and a foldable pin 4 corresponding to the ground, the foldable pin 4 comprises an inserting section 5 and a shaft connecting section 6, the inserting section 5 and the shaft connecting section 6 are connected together in an L shape, the housing 1 is provided with a front end face and a receiving groove 7 for receiving the foldable pin 4 on the upper and lower surfaces adjacent to the front end face, the foldable pins 4 are rotatably connected to the receiving grooves 7 of the housing 1 at the shaft connecting sections through a short shaft 8, so that the plug section 5 of the foldable plug pin 4 corresponds to the corresponding ground wire jack of the three-jack socket when the foldable plug pin 4 is opened, and the foldable plug pin 4 can be accommodated into the accommodating groove 7 after being folded.

The shaft connecting section 6 of the foldable pin 4 is provided with a locking clamping block 9 protruding towards the side, a shaft hole connected with the short shaft 8 on the foldable pin 4 is a long hole, the accommodating groove 7 of the shell 1 is respectively provided with a locking bayonet 10 and an accommodating bayonet 11 corresponding to the locking clamping block 9 on the upper surface and the front end surface, the foldable pin 4 can be embedded into the locking bayonet 10 by pressing down after being opened to achieve the purpose of locking, and the locking clamping block 9 of the foldable pin 4 is enabled to correspond to the accommodating bayonet 11 after being folded to play a role of not obstructing the accommodation.

The outer corner of the connection between the plug-in section 5 and the shaft connecting section 6 of the foldable pin 4 is provided with a protrusion 12 which is convenient to open, and the foldable pin 4 can be opened by applying force to the protrusion 12.

The foldable pin 4 is connected with a corresponding ground wire of an electric appliance through a spring leaf 13, the spring leaf 13 is fixed in the shell 1, one end of the spring leaf is provided with a wire connecting part 14, and the other end of the spring leaf is in contact and electric connection with the unfolded foldable pin 4.

The shell 1 comprises an inner shell 15 and an outer shell 16, wherein the variable angle pins 2 and the foldable pins 4 are fixed on the inner shell 15, and the outer shell 16 is covered outside the inner shell.

The spring piece connected with the foldable pin can be embedded into the shell or connected and fixed with the shell through a screw. Interior casing and shell body all can make the structure of two halves, interior casing is equipped with the inlay card groove and the shaft hole of connecting three participating in, the back has been placed to three participating in, the casing just can make and participate in fixedly in lock two halves, two half shell bodies then can be through the screw from the periphery fix at interior casing periphery (the spring leaf needs corresponding buckling in order to dodge out the screw), also can be fixed outside the inner shell body through the veneer connection, but need set up the window of being convenient for the wiring alone (can refer to the connection structure of current plug, structure commonly used).
