Description
Technical field
The utility model relates to electric elements technical field, particularly relates to a kind of inner bracket of power plug and attaching plug.
Background technology
Attaching plug most in the market and socket Main Basis GB GB2099.1-2008, GB2099.3-2008, GB1002-2008, GB1003-2008 are made.There are Single-phase plug and 3-phase plug by single-phase and three-phase classification, wherein can be divided into again single-phase the two poles of the earth plug and single-phase the two poles of the earth grounded plug for Single-phase plug by with or without earth connection.
In live and work at ordinary times, we often can encounter electric equipment (computer, hair-dryer, charger etc.) the plug problem of attaching plug, general attaching plug is substantially no problem when inserting, but some difficulties can be met when extracting: such as often need when extracting to use larger strength, or need to use two hand-liftings simultaneously, specifically, when unplugg, for Mobile electrical source socket (insert row), general needs hand pins socket, another hand firmly pulls out, and for fixing type socket (such as wall socket), best mode is also that a hand pins socket, another hand is exerted oneself unplugg, if singlehanded unplugg, socket is easy to loosen or depart from from wall, and then cause the dangerous things such as short circuit to occur.
Present imagination such as interts a thimble in order to realize can pulling out soon by one hand of attaching plug on attaching plug body, but, our common attaching plug at present, no matter be the two poles of the earth or three poles, its structure is all one substantially, generally on attaching plug, also can not through hole being set, so just need to arrange through hole when making inner bracket of power plug, and existing inner bracket of power plug cannot realizing.
In order to solve the problem, the utility model proposes and a kind ofly can realize the singlehanded inner bracket of power plug and the attaching plug that pull out function soon safely and effectively.
Utility model content
The utility model overcomes above-mentioned the deficiencies in the prior art, proposes a kind ofly can realize the singlehanded inner bracket of power plug and the attaching plug that pull out function soon safely and effectively.
The technical solution of the utility model is achieved in that
A kind of inner bracket of power plug, comprise internal frame body, described internal frame body comprises upper bracket and lower carriage, and lower carriage has the through hole A of a up/down perforation and multiple jack around through hole A; Upper bracket comprises a hollow cylinder A, the outer peripheral edges of hollow cylinder A upper part be fixed with around and perpendicular to the supporting bracket of hollow cylinder A; The metal pin that one end is connected with power line is interspersed with in the jack of lower carriage, then hollow cylinder A is vertically set on lower carriage and the lower end of hollow cylinder A to match with through hole A and be fixedly connected with, the hollow space of hollow cylinder A and through hole A form a through elongated hole, and upper bracket and lower carriage are integrated.
Here structure logical during through hole A lower carriage had and the hollow space of hollow cylinder A make whole internal frame body define, provide the foundation for the one hand realizing plug pulls out function soon, and the structure arranging hollow cylinder A also strengthens the firmness of internal frame body and the internal frame body plug used joined together, hollow cylinder A arranges supporting bracket, both the intensity of internal frame body construction and the intensity of its whole attaching plug used joined together can have been strengthened, also the inner frame in socket handle portion can be served as when realizing one hand and pulling out soon, bear certain power, improve structural strength, extend useful life, it is pointed out that upper bracket that to be first arranged to by internal frame body be separated and lower carriage are the requirements in order to production technology, upper bracket is separated with lower carriage, can first intert on lower carriage by metal pin, is then fixed on lower carriage by upper bracket cooperation, if upper bracket and lower carriage were just made of one before interspersed metal pin, due to supporting bracket, such meeting is arranged so that metal pin is difficult to insert in the jack of lower carriage, unless made the distance between supporting bracket and lower carriage increase the height namely strengthening hollow cylinder A, thus make supporting bracket, can form enough spaces between hollow cylinder A and lower carriage makes metal pin enter, and intert in jack, so, if upper bracket and lower carriage were just made of one before interspersed metal pin, high hollow cylinder A can only be, so not only there is no need, and also improve the amount of materials, improve cost, therefore, internal frame body is arranged to upper bracket and the lower carriage of separation, not only be conducive to the installation of metal pin, but cost-saving needs, and do not affect firmness and the use of internal frame body.
