Description

Waterproof socket of multiaspect grafting square

Technical Field

The invention relates to the technical field of household appliances, in particular to a multi-surface plug-in square waterproof socket.

Background

The socket is also called a power socket or a switch socket, and the socket is a socket into which one or more circuit wiring can be inserted, various wiring can be inserted through the socket, so that the socket is convenient to be connected with other circuits, and the connection and disconnection between a circuit and a copper piece are realized to finally achieve the connection and disconnection of the partial circuit.

The patent of bulletin number CN204464615U, CN2696167Y discloses a waterproof socket module and combination formula wall body switch socket, including socket main body and rotatory apron, socket main body on set up circular recess, rotatory apron is rotatable installs on the opening of circular recess, socket main body's circular recess in set up elastic component, elastic component's one end is fixed, the other end is used in rotatory apron, elastic component is out of shape when power plug inserts, elastic component acts on rotatory apron and makes it reset after power plug extracts, though this utility model is waterproof, but when needs connect power plug, need a hand to rotate rotatory apron, another hand is taken power plug and just can insert, the operation is comparatively troublesome, and this socket can only be fixed in the wall body, can not remove at will, looks in addition. In addition, the conventional patent document CN207021421U adopts a rotatable locking mechanism which can be accommodated in the protective cover and can be used for switching the use state of the socket through the rotation locking mechanism, but in the structure, the socket can be connected and used only on one side, so the pluggable space is small, the practicability is not strong, the sucker of the socket in CN207353622U extends out of a overlong length and needs to be attracted and matched by a magnet when the protective cover rotates, the waterproof effect of the socket is limited, and the sealing and waterproof effect can be realized only by using a rubber material, but the rubber material, such as a rubber sleeve, makes the damping of the rotating part on two sides of the sleeve difficult to adjust, the rotation is not flexible enough, and a pre-pressure or a pre-pressure structure needs to be applied when the socket is assembled, and a precise hole opening.
