Abstract
The utility model discloses a kind of bike metal hollow tube, it comprises single body, is characterized in, at least one section caliber or dwindle or enlarge on the single body, the thickness of pipe or increase or minimizing, part are non-round tube, and integral body is one-body molded also can curved moulding pipe.The difference of the thickness of pipe, caliber, non-pipe moulding can be a place or many places on its single body, so that in suitable place suitable intensity or moulding are arranged.Its crooked part can be a place or many places on the single body, so that have more variability and aesthetic property on the shape visual effect.Can pipe fitting be processed into the pipe fitting with various curve modelings according to different demands, as coil pipe etc.Under lower cost, strengthen local strength, on the shape visual effect, have more variability and aesthetic property.
Description
Technical field
The utility model is relevant with bicycle pipe part, relates to the pipe fitting that constitutes cycle frame, front fork and handle, especially the bike metal hollow tube.
Background technology
For many years, the vehicle frame of the round straight tube moulding of bicycle dullness or annex can't reach the integrated demand of optimal intensity and outward appearance with the functions of use of car load.
In the prior art, when desiring to make its different parts of pipe fitting that constitutes cycle frame, front fork and handle to have different requirement of strength, have and process the thickness that makes tube wall from pipe fitting inside and change and meet the requirements of; Pipe fitting with welding different-thickness, caliber is also arranged, or utilize reinforcing chip to meet the requirements of.
Above-mentioned two kinds of methods, not only manufacturing procedure complexity, tooling cost height, and can be because of the variation intensity of welding, and make bicycle pipe part can't reach stable quality, more do not have variability and aesthetic property in the pipe fitting moulding.
Summary of the invention
The purpose of this utility model is to provide a kind of improved bike metal hollow tube, with external process and whole integrated mode, the cast variation of single body part is reached to have different demand intensities and whole curved moulding pipe, to strengthen the aesthetic feeling of vehicle modeling.
The purpose of this utility model is achieved in that
The bike metal hollow tube, it comprises body, its substantive distinguishing features is: at least one section caliber or dwindle or enlarge on the described body, the thickness of pipe or increase or minimizing, the part is non-round tube, whole one-body molded also can curved moulding pipe.
Above-mentioned bike metal hollow tube, wherein, thickness of pipe difference is a place or many places on the described body.
Above-mentioned bike metal hollow tube, wherein, the caliber difference is a place or many places on the described single body.
Above-mentioned bike metal hollow tube, wherein, non-round tube part is a place or many places on the described single body.
Above-mentioned bike metal hollow tube, wherein, its crooked part is a place or many places on the described single body.
Bike metal hollow tube of the present utility model makes it compared with prior art owing to adopted above-mentioned technical scheme, has following advantage and good effect:
Because the utility model bike metal hollow tube is reached single its local different demand intensities of body with outside process variations moulding, and it is whole one-body molded, therefore, not only tooling cost is low, the pipe fitting stay in grade, also can pipe fitting be processed into the pipe fitting with various curve modelings, as coil pipe etc. according to different demands.
Description of drawings
By the description of a following embodiment to the utility model bike metal hollow tube, can further understand purpose of the present invention, specific structural features and advantage in conjunction with its accompanying drawing.Wherein, accompanying drawing is:
Fig. 1 is the perspective view of the utility model bike metal hollow tube;
Fig. 2 is the metamorphosis scheme drawing in the utility model bike metal hollow tube course of processing.
The specific embodiment
Referring to Fig. 1, cooperate referring to Fig. 2, shown in the figure the utility model bike metal hollow tube, it comprises single body 1, at least one section caliber or dwindle or enlarge the thickness of pipe or increase or minimizing on its single body 1, the part is non-round tube, and integral body is one-body molded also can curved moulding pipe.
Wherein, the difference of its caliber, the thickness of pipe, non-pipe moulding can be a place or many places on the single body 1, so that in suitable place suitable intensity or moulding are arranged.
Its crooked part can be a place or many places on the body 1, so that have more variability and aesthetic property on the shape visual effect.
The utility model is that the pipe material at a suitable caliber dwindles its caliber through external process, increases and reach the thickness of pipe, to increase its intensity; Clap flat to increase the intensity that it is subjected to force direction; Bend increasing its elasticity and moulding, its one machine-shaping not only reaches and has intensity, variation and attractive in appearance and its cost is lower concurrently.Make processing characteristics that processing mode and one shape the pipe material and use any one part so get it, but not vehicle frame only to bicycle, front fork, and reach the value added of car load.
The bicycle quality function is if reach, can add whole moulded again, just more can increase its value added, can pipe fitting be processed into pipe fitting according to different demands with various curve modelings, coil pipe of the present utility model is an example wherein, because of adding sinuousness, just more increase its value added.
