Specific embodiment
Below with reference to the accompanying drawings and in conjunction with the embodiments the utility model is described in detail.It should be noted that not rushing
In the case of prominent, the feature in following embodiment and embodiment can be combined with each other.
Fig. 1~Fig. 2 gives inclined circular tube structure schematic diagram in the photographic goods carbon fiber of the utility model, can by figure
Know, inclined pipe in the photographic goods carbon fiber, including connecting circle 10 and round platform ladder cylinder 20 in section partially, connect partially in section
Circle 1 is connect as isometrical circular arc mutual dislocation of the central angle that the center of circle overlaps less than 180 and passes through fillet and straightway connects shape
Into connection circle, round platform ladder cylinder 20 be three ladders of the head with round platform cylinder.
Connection circle 10 is partially round including the inclined circular arc 11 of upper right, S types knuckle 12, flat inclined connecting line 13 and lower-left partially in section
Arc 14, the inclined circular arc 14 of the inclined circular arc 11 of upper right and lower-left for etc. the isometrical central angle of arc length be less than 180 degree vertical direction it is left respectively
The arc section that side is downward, upward one fixed range of mutual dislocation in the right is formed, the central angle line of the inclined circular arc 11 of upper right it is offline
Section is vertically arranged, and the upper line segment of the central angle line of the inclined circular arc 14 in lower-left is vertically arranged, and S types knuckle 12 is opposite for direction
Isometrical knuckle, it be to connect S types knuckle 12 and the inclined circular arc 14 of the inclined circular arc 11 of upper right or lower-left to put down inclined connecting line 13
Straightway.
The circular arc central angle a of the inclined circular arc 14 of the inclined circular arc 11 of upper right and lower-left is 173 ± 3 degree, above and below upper and lower dislocation distance
Offset distance H is 0.55mm.The flat inclined line length for putting down inclined connecting line 13 is 1mm.
