Background technology
Lighting of the prior art is installed on the ceiling mostly, whole room is thrown light on, and when people need read the books newspaper or write thing, utilize the lighting on the ceiling to throw light on, and is easy to generate projection, and influence is used.And when utilizing desk lamp to throw light on, then need desk lamp is placed on the desktop, can take the desktop place first, can produce inconvenience to the user first, touched down easily on the ground, damage light fixture.Light fixture is placed on the ground then needs very long connecting rod, and on the one hand, long connecting rod takies too big space in the time of can causing packing, and on the other hand, long connecting rod also can bring inconvenience to connecting power line, connects so extremely use split instead
Summary of the invention
Use inconvenience at lighting in the above-mentioned prior art of mentioning, it is big to take up room during production, the shortcoming of making troubles to manufacturing, the utility model provides a kind of standard lamp adapter, utilize the utility model that a plurality of support bars are linked together, can prolong standard lamp support bar length, and economical with materials, conveniently connect power line.
The technical scheme that its technical problem that solves the utility model adopts is: a kind of standard lamp adapter, adapter is divided into intermediate transit head and end adapter, the end adapter is located at standard lamp support bar one end, the intermediate transit head is used to connect two sections support bars, its structure is: end adapter and intermediate transit head are columnar structured, the outside is provided with connecting thread, inner for connecting the hollow-core construction that power line is used, the end adapter outside one end is provided with connecting thread, the other end is no screw thread light face, the outer two ends of intermediate transit head are provided with connecting thread, and middle is no screw thread light face.
The technical scheme that its technical problem that solves the utility model adopts further comprises:
Described adapter connecting thread and do not have the outer electrodeposited coating that is provided with colors such as bronze, bronze, nickel sand in the facial position of screw thread light.
Described adapter adopts hard plastic injection molding to process.
Described end adapter internal layer can be provided with to install uses internal thread.
Described end adapter internal layer is provided with the internal thread restriction protrusion.
Described end adapter internal layer is provided with the internal thread extension plate.
Described adapter internal layer is provided with the projection of spacing usefulness.
The beneficial effects of the utility model are: the utility model can be simplified the production process of standard lamp, conveniently connects power line, and production technology is simple, saves production cost.
The utility model is described in further detail below in conjunction with the drawings and specific embodiments.

Embodiment
Present embodiment is the utility model preferred implementation, and other all its principle is identical with basic structure and present embodiment or approximate, all within the utility model protection range.
In the present embodiment, adopt rigid plastics to process, after the machine-shaping, can be coated with ornamental ornament materials in the adapter outside by injection molding machine typing injection moulding, available spray paint or the mode of baking vanish scribbles decorative paint in the above, or utilize mode such as plating to be provided with electroplated decoration coating etc. in the above.Its concrete machining shape is as described below:
Referring to accompanying drawing, Fig. 1 to Fig. 6 is the utility model end adapter cross-sectional view.The end adapter is a cylindrical shape, and the centre is a hollow-core construction, connects power lead etc. with convenient portion within it.The outside end of end adapter is provided with external screw thread and is used to connect the standard lamp support bar, the other end is provided with ornamental no screw thread ornamental area, and no screw thread light face is circular, and its edge can be axially vertical with adapter, also can be axially angled with adapter, as 30 degree, 45 degree.End adapter inside can be provided with internal thread, also can not establish, when the end adapter is used for the standard lamp support bar top, internal thread can not established in its inside, when adapter was used for standard lamp support bar centre position, internal thread need be established in its inside, to connect the ramuscule strut above the convenient end adapter.When end adapter wall was thin, the wall setting of internal thread place was thicker, can be designed to steppedly, when the internal thread thickened wall is thin in the axial direction, in order to increase its useful life and quality of connection, can design the internal thread extension plate, was used to reinforce the connection of internal thread.In order to limit end adapter and the interconnective distance of support bar, be provided with the spacing projection of using in the inboard relevant position of end adapter.
