Description
Technical field
The utility model relates to Pop-up plug fields, and in particular to the plug of the Pulling-free plug with bolt position limiting structure
Exempt from draft block.
Background technique
Plug is to cooperate to introduce power supply to the component of electric appliance for same socket.The basic structure of plug include plug body and
Be connected to the inserted sheet (also known as bolt) of plug body, when use be inserted into the jack of socket by inserted sheet after with sleeve be connected to one
It rises and draws power supply.In order to guarantee being reliably connected between sleeve and inserted sheet, sleeve can be designed as with biggish chucking power folder
It holds on inserted sheet, in order to pull the plug out of the socket from mobile socket, needs that a hand pins socket, another hand catches the mode of plug
It is extracted, it is necessary to which two hands operate simultaneously, inconvenient when causing to extract, if chucking power is very big or user's strength is smaller
When, user need on one side exert oneself to pull out outward, while shake plug to both sides and plug can be extracted, will will lead to so slotting
The improper decline of the sleeve chucking power of seat falls off with wall socket.
It is existing exempt to pull out safety plug be also referred to as spring plug, principle is that a telescopic elastic device is arranged between bolt,
Telescopic elastic device is compressed after plug is inserted into socket, is limited in minimum stroke, is led to when needing to pull the plug out of the socket
It crosses and the buttons of plug two sides is set telescopic elastic ejector pin is forced to reset, plug is ejected into socket, this production while reset
Product can make operator easily pull the plug out of the socket, quick separating, without the unplugg when shaking, prevent Danger Electric shock risk when unplugg, protect
It protects people and protects electric appliance, and one-handed performance can easily pull the plug out of the socket, and go to push down socket without another hand, be inserted into and move in plug
In the case where socket, another hand does not push down socket, is that cannot extract plug, for normal person, greatly facilitates
User, for only having for the disabled person of a hand, such product will greatly promote it and operate convenience, become the disable person's
Inevitable choice.
But when being inserted into socket due to plug, bolt must endure as biggish insertion force, therefore have the generation for retreating phenomenon,
Plug bolt when long-time plugs retreats return repeatedly, will cause the reduction of bolt height, and is easy to cause safety accident.
