Abstract
The utility model relates to an inclined 'D'-shaped pipe of bus window, wherein the section of the pipe body (1) of the inclined 'D'-shaped pipe is in inclined 'D'-shaped structure, the inclined 'D'-shaped structure contains a long straight edge segment (1-1), a short straight edge segment (1-2), a long beveled edge segment (1-3), a short beveled edge segment (1-4) and an arc segment (1-5), the connection between either two edge segments of the pipe body (1) are arc transitions, a galvanizing layer (2) is coated on the surface of the pipe body (1), and the material of the 'D'-shaped pipe is Q345B. The inclined 'D'-shaped pipe of bus window has lighter weight, high intensity, stronger non-corrodibility, smoothing pipe body surface and elegant shapes.
Description
(1) technical field
The utility model relates to a kind of special-shaped seamless steel pipe, especially relates to a kind of Bus window with oblique " D " shape pipe, belongs to the metallic material technical field.
(2) background technique
At present, seamless steel pipe is widely used in manufacturing structure spare and mechanical parts, as steel scaffold of using in oil drill rocker, truck drive shaft, bicycle frame and the construction etc.Make ring-shaped work pieces with seamless steel pipe, can improve stock utilization, simplify manufacturing process, economical with materials and machining period as rolling bearing lasso, jack cover etc., are extensively made with seamless steel pipe at present.Seamless steel pipe still is various conventional weapon indispensable material, and gun barrel, gun barrel etc. is all wanted steel pipe manufacturing.In these seamless steel pipes, circular pipe can be carried more fluid.In addition, ring cross-section is when bearing inside or outer radial pressure, and is stressed more even, and therefore most seamless steel pipes are pipes.
Yet pipe also has certain narrow limitation:
The shape restriction of pipe makes it can't be used for some particular surroundingss;
Because the moment of inertia of pipe and section modulus are less, its bending resistance and anti-twisting property are relatively poor, and intensity is low;
The weight of pipe itself is bigger, and is bigger to the pressure of its supporting part.
Above a variety of causes has limited the Applicable scope of pipe, does not therefore adopt pipe to be used as structural member or machine part under some particular surroundingss.For example Bus window needs its pipe fitting to have high strength, etch-proof performance, and weight is light, surface smoothing, and shape is attractive in appearance, so just can not use pipe to make.
(3) summary of the invention
In order to overcome above-mentioned deficiency, the utility model provides a kind of Bus window to manage with oblique " D " shape, and this Bus window is lighter with the weight of oblique " D " shape pipe, the intensity height, and Corrosion Protection is strong, and the body surface smoothing, and shape is elegant in appearance.
The purpose of this utility model is achieved in that
A kind of Bus window is managed with oblique " D " shape, tiltedly the section of the body of " D " shape pipe is tiltedly " D " shape structure, tiltedly " D " shape structure includes long straight section, short straight section, long hypotenuse section, short hypotenuse section and arc section, the top of described body and bottom are long straight section, the left side of described body is long hypotenuse section, the two ends of described long hypotenuse section link to each other with the long straight section of top and bottom respectively, the right-hand member of the long straight section at described top links to each other with short hypotenuse section, described short hypotenuse section links to each other with short straight section, the right-hand member of described short straight section links to each other with arc section, the lower end of described arc section links to each other with the long straight section of bottom, be connected to arc transition between each limit section of described body, described body surface is covered with zinc coat, and the described tiltedly material of " D " shape pipe is Q345B.
The beneficial effect that the utlity model has is:
This Bus window is lighter with the weight of oblique " D " shape pipe, the intensity height, and Corrosion Protection is strong, the body surface smoothing, shape is elegant in appearance.
(4) description of drawings
Fig. 1 is the cross-sectional configuration schematic representation of the utility model Bus window with oblique " D " shape pipe.
Wherein: body 1, long straight section 1-1, short straight section 1-2, long hypotenuse section 1-3, short hypotenuse section 1-4, arc section 1-5, zinc coat 2.
(5) embodiment
As Fig. 1, the utility model relates to a kind of Bus window and manages with oblique " D " shape, tiltedly the section of the body 1 of " D " shape pipe is tiltedly " D " shape structure, tiltedly " D " shape structure includes long straight section 1-1, short straight section 1-2, long hypotenuse section 1-3, short hypotenuse section 1-4 and arc section 1-5, the top of described body 1 and bottom are long straight section 1-1, the left side of described body 1 is long hypotenuse section 1-3, the two ends of described long hypotenuse section 1-3 link to each other with the long straight section 1-1 of top and bottom respectively, the right-hand member of the long straight section 1-1 at described top links to each other with short hypotenuse section 1-4, described short hypotenuse section 1-4 links to each other with short straight section 1-2, the right-hand member of described short straight section 1-2 links to each other with arc section 1-5, the lower end of described arc section 1-5 links to each other with the long straight section 1-1 of bottom, be connected to arc transition between described body 1 each limit section, described body 1 surface is covered with zinc coat 2, and the described tiltedly material of " D " shape pipe is Q345B.
Claims (1)
