Change-over plug

Technical Field

The utility model relates to an electrical equipment, in particular to changeover plug.

Background

The conversion plug is used for converting a certain plug into another plug (such as a telephone power plug, a USB charging plug and a computer power plug, and the universal plug is used for interchanging power plugs of various countries and the like). The universal power plug is characterized in that different power plugs of different countries or a power plug of a certain country are converted into a power plug of another country or a plurality of countries, and the power plug of the plurality of countries or the power plug of the certain country can be plugged into a socket of another country, so that the plugs of different countries can be communicated with each other in different countries around the world, and the problem that electric appliances of different countries around the world can be used in other countries is solved. The power utilization plugs in the world comprise a Chinese standard, an American standard, an European standard, a British standard and a south Africa standard, different socket standards are often adopted in different regions, inconvenience is brought to people who often go abroad, and electronic equipment such as mobile phones and notebook computers is difficult to charge.

Chinese patent with publication number CN208986252U discloses a rotary travel conversion plug with a lamp, which comprises an upper cover, an L/N pole clamping piece and a lower cover, wherein the upper cover and the lower cover are buckled together to form a buckling position assembly, the L/N pole clamping piece is arranged inside the lower cover, a through hole is formed in the bottom of the lower cover, a UL copper pin is arranged inside the lower cover, and the lower end of the UL copper pin penetrates through the through hole and extends to the lower part of the lower cover.

Set up the jack in the above-mentioned patent on covering, the plug passes through the jack and inserts to the inside and the contact of L/N utmost point clamping piece of upper cover to realize switching on of circuit. Because there is not any safety device between jack and the utmost point clamping piece of L/N in above-mentioned patent, if the infant inserts the jack and contacts with utmost point clamping piece of L/N in the while playing finger, can cause personal safety accident, has very big potential safety hazard.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing a change over plug, this change over plug can avoid the potential safety hazard that exists.

The above technical purpose of the present invention can be achieved by the following technical solutions: the utility model provides a changeover plug, includes the shell and sets up in the upper cover of shell, the inside installation cavity that forms of shell and upper cover, be equipped with electrically conductive piece in the installation cavity, be equipped with the copper foot of being connected with electrically conductive piece electricity on the shell, the upper cover just is equipped with the jack of intercommunication installation cavity corresponding to the position of electrically conductive piece, the position that is located jack and electrically conductive piece in the installation cavity forms a smooth chamber, it is provided with portable to jack and electrically conductive emergency exit between the two in the smooth intracavity to slide, be equipped with the emergency exit that resets to jack and electrically conductive piece between the two in the smooth intracavity.

Through adopting above-mentioned technical scheme, the plug injects the jack and exerts great effort to the emergency exit that sets up between jack and electrically conductive piece to the drive emergency exit slides in sliding chamber, makes the emergency exit slide to the orthographic projection position of keeping away from the jack, just so can realize the contact of plug and electrically conductive piece, makes the circuit switch on. When the plug is pulled out from the jack, the safety door loses the blockage of the plug, the safety door resets to the position between the jack and the conductive piece under the action of the resetting piece, so that the fingers of the infant can be blocked by the safety door when stretching into the jack, the contact between the fingers of the infant and the conductive piece is prevented, and the potential safety hazard is avoided.

Further setting the following steps: reset the piece and include reset spring, reset spring sets up between emergency exit and installation cavity inner wall and is used for driving the emergency exit and slides, one side and the installation cavity inner wall of emergency exit back to reset spring offset, works as when emergency exit offsets with installation cavity inner wall, the emergency exit is located between electrically conductive and the jack.

Through adopting above-mentioned technical scheme, reset spring drive emergency exit offsets in the inner wall of installation cavity, prescribes a limit to the position of emergency exit, and offsets in the emergency exit of installation cavity inner wall just to be located between jack and the electrically conductive piece, and such setting up simple structure and convenient equipment, the processing cost is low.

Further setting the following steps: the safety door comprises a first safety door and a second safety door, wherein the number of the safety doors is two, the first safety door and the second safety door are respectively arranged, an anti-single-plug bolt capable of sliding back and forth between the first safety door and the second safety door is arranged in the installation cavity, a driving spring for driving the anti-single-plug bolt to move towards the first safety door is arranged between the anti-single-plug bolt and the installation cavity, a first linkage component for driving the anti-single-plug bolt to move towards the second safety door is arranged between the first safety door and the anti-single-plug bolt, and a first limiting component for limiting the anti-single-plug bolt to move towards the second safety door and a second limiting component for limiting the second safety door to slide are formed between the second safety door and the anti-single-plug bolt;

when the first safety door drives the anti-single-plug bolt to move towards the second safety door through the first linkage member, the first limiting member limits the anti-single-plug bolt to move towards the second safety door, and when the second safety door moves towards the anti-single-plug bolt, the second limiting member limits the second safety door to move towards the anti-single-plug bolt;

when the first safety door and the second safety door synchronously move towards the anti-single-plug bolt and the first linkage component is not triggered to act, the second limiting component limits the second safety door, and the first limiting component does not limit the anti-single-plug bolt;
