[specific embodiment]
In specification sheets, the shape of bicycle folding mechanism, size can not done special restriction, can suitably adjust according to actual needs.
In specification sheets, the explanation of all direction, be only to narrate and help reader understanding the present invention for more convenient, rather than restriction the present invention, particularly can not be interpreted as the restriction that position, orientation are applied the present invention, because if narration conversely, position, orientation also will be opposite.
In specification sheets, the making material of bicycle folding mechanism can not done special restriction, can select metal or non-metallic material to make, the tubing that aluminum commonly used or steel material are made when selecting metallic material.
Below in conjunction with accompanying drawing, by the specific embodiment of the present invention is further described, make technical scheme of the present invention and beneficial effect thereof clearer, clear and definite.
Refer to shown in Figure 1ly, it,, for a kind of bicycle folding mechanism that preferred embodiments of the present invention provides, comprises the main body spider, and described main body spider comprises the first armed lever 1, the second armed lever 2 and the 3rd armed lever 3; Described the second armed lever 2 is installed in the top of described the first armed lever 2 by socket join structure 4, described the 3rd armed lever 3 is divided into lower branch arm 31 and upper branch arm 32, described lower branch arm 32 removably is assembled in described upper branch arm 32 by adapter 5, changes unfolding between state and deployed condition with this bicycle folding mechanism.
As shown in Figure 2, the concrete structure of socket join structure 4, it comprises the sleeve pipe 41 that is fixed in described the second armed lever 2, is positioned at the damper element 42 of all sleeve pipes 41.The below of described socket join structure 4 is provided with anti-pivoted arm 6, and top is provided with swivel nut 7, and described anti-pivoted arm 6 and described swivel nut 7 are all established Locking Device 71.
As shown in Figure 3 and Figure 4, the concrete structure of adapter 5, it comprises the joint 1 that is fixed in described lower branch arm 31, the joint 2 52 that is fixed in described upper branch arm 32, and the adapter sleeve 53 that is connected in described joint 1 and described joint 2 52.Joint 1 and the affixed form of joint 2 52 can select to adopt the mode of welding, the outer surface thread section 511 that joint 1 is provided with and spline 512, described joint 2 52 is provided with the spline 521 for accommodating described spline 512, and described adapter sleeve 53 is provided with internal thread segment 531; It is fixing that described adapter sleeve 53 is bolted in described joint 1.Spline 512 and spline 521 coordinate stressed face width, and Stability Analysis of Structures is not easy loosening phenomenon, effectively improves the problem of cyclery regularity oftimekeeping and vibration.
