Description

Technical Field

[0001] The utility model relates to the technical field of plugs, in particular to a rotating and retracting structure of a power plug. Background Art

[0002] The connectors of electronic products and the plugs of electrical appliances are called plugs. Household AC power plugs and sockets have male connectors with rod-shaped or copper-plate protrusions, which are physically inserted into female connector-type power sockets with slots or recesses. The size is an important technical requirement related to whether plugs, sockets and converters can be used safely and whether they meet the general interchangeability requirements to avoid misinsertion. Unqualified size will affect user use or cause hidden dangers such as poor contact and misinsertion, which may damage the equipment at the least and cause fire and electric shock accidents at the worst.

[0003] With the development of society and the accelerated pace of life, people travel and tour across regions and countries more and more frequently, and electronic devices such as mobile phones have become indispensable equipment in people's lives. Therefore, in order to ensure that the mobile phone can be used normally during business trips and travels, people will carry a power plug with them. However, in the current market, the existing power plugs have fixed pins, which cannot be retracted into the main body when being carried or not in use, resulting in more space being occupied when carrying, and thus inconvenient to carry. In addition, the fixed pins are also easily hit against other objects during carrying. At this time, the sharp pins are also easy to hurt other objects. In addition, the fixed pins are exposed to the outside for a long time, which will also cause corrosion, scratches, damage, etc., and thus there will be hidden safety hazards in use. Therefore, the utility model proposes a rotating and retracting structure of a power plug to solve the problems existing in the prior art. Utility Model Content

[0004] In view of the above problems, the utility model proposes a rotating and retracting structure of a power plug. The rotating and retracting structure of the power plug rotates a rotating cover to rotate the gear ring, which drives the gear to rotate and drives the screw rod to rotate. The thread action can drive the insulating block to slide on the guide rod, thereby driving the power connector to move, making it easy to extend or retract, avoiding scratches on other objects, and also avoiding corrosion, scratches, damage, etc.

[0005] To achieve the purpose of the utility model, the utility model is implemented by the following technical solutions: a power plug rotation and contraction structure, including a plug socket and a rotating cover, the rotating cover is rotatably arranged at one end of the plug socket, both sides of the plug socket are provided with guide rods, and an insulating block is slidably arranged on the guide rods, one end of the insulating block is provided with an electric connection head, and the electric connection head extends out of the plug socket;
