A kind of butt-ended tube for light fixture bracing frame
Technical field
The utility model relates to field of illuminating lamps, especially a kind of pipe for light fixture bracing frame.
Background technology
At present, the lampshade that common a kind of light fixture comprises light fixture bracing frame and is wrapped in outside bracing frame, normally take the lead and be processed with external screw thread in pipe one end for light fixture bracing frame, when installing lampshade, this externally threaded part will through the mesopore of Lamp shade holder connecting portion, and by the position jack-up Lamp shade holder and strut lampshade of taking the lead of pipe, but there is certain length due to external screw thread top and position of taking the lead, make the length of whole light fixture bracing frame be greater than lampshade length, cause the installation of lampshade to encounter difficulties; For the shortcoming existing for existing light fixture support frame structure, be necessary to make improvement.
Summary of the invention
For addressing the aforementioned drawbacks, the utility model proposes a kind of simple and reasonable for structure, be convenient to produce assembling the butt-ended tube for light fixture bracing frame.
The utility model solves the technical scheme that its technical problem adopts:
For a butt-ended tube for light fixture bracing frame, the one end comprising pipe is provided with tack, and one end that this pipe described is provided with tack is provided with interior pitch thread, and this interior pitch thread is connected and fixed by screwed pipe and Lamp shade holder.
In the utility model, described pipe one or both ends are provided with tack, and this tack size is greater than pipe diameter, for plane or indent or evagination have the shape of gliding surfaces simultaneously.
The beneficial effects of the utility model are: because the utility model have employed the pipe that one end is provided with tack, eliminate the male thread portion of pipe of originally taking the lead, change into and be provided with tack and the interior pitch thread of processing, due to the length without former male-pipe, thus avoid the length of whole light fixture bracing frame to be greater than lampshade length, overcome the difficulty that lampshade is installed.
Accompanying drawing explanation
Below in conjunction with drawings and Examples, the utility model is further illustrated.
Fig. 1 is structural representation of the present utility model, comprises the butt-ended tube of a plane and a convex shape, and one improve before tradition to take the lead pipe;
Fig. 2 adopts light fixture of the present utility model to implement scheme of installation;
Fig. 3 is the A enlarged drawing of Fig. 2;
Fig. 4 is the B enlarged drawing of Fig. 2.
Detailed description of the invention
With reference to Fig. 1, Fig. 2, Fig. 3, Fig. 4, a kind of butt-ended tube for light fixture bracing frame, comprise the pipe that one end is provided with tack (1), one end that this pipe described is provided with tack (1) is provided with interior pitch thread (2), is connected and fixed by screwed pipe (3) and Lamp shade holder (4).
Because the utility model have employed the pipe that one end is provided with tack, the length of whole light fixture bracing frame equals lampshade length, when lampshade is installed, the connecting portion of Lamp shade holder (4) withstands on the tack (1) of light fixture bracing frame i.e. described butt-ended tube, and lampshade is strutted, use screwed pipe (3) through the mesopore of Lamp shade holder (4) connecting portion again, the interior pitch thread (2) being spun on described butt-ended tube tack (1) one end is inner, finally lampshade and light fixture bracing frame is connected and fixed.
Wherein, light fixture bracing frame is formed by connecting by one or more of butt-ended tube and pipe of not taking the lead.
The utility model is skillfully constructed, structure simple, is convenient to produce install, and is a kind of widely used butt-ended tube for light fixture bracing frame.
More than that better enforcement of the present utility model is illustrated, but the invention is not limited to described embodiment, those of ordinary skill in the art also can make all equivalent variations or replacement under the prerequisite without prejudice to the utility model spirit, and these equivalent modification or replacement are all included in the application's claim limited range.
