Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in detail below in with reference to the accompanying drawings and embodiments.
The utility model discloses a bicycle can be dismantled to single arm, as shown in fig. 1-5, including fore-stock 1, back single arm 2, connecting device 3, rear wheel 4, front fork 6, front wheel 7 and well pipe 8, front wheel 7 passes through front fork 6 and installs on fore-stock 1, rear wheel 4 installs on back single arm 2, fore-stock 1 and back single arm 2 pass through connecting device 3 fixed connection, wherein, connecting device 3 includes two clamp splice 31 and retaining member 32, wherein, clamp splice 31 is L shape, the concave semicircle pipe 311 that establishes on its inboard side edge, two clamp splice 31 concatenations form the installation pipe 33 of well pipe 8 in the installation, clamp splice 31 is fixed through retaining member 32 specific inboard side, two clamp splice 31 are clamp splice 91 and second clamp splice 92 respectively, the top of clamp splice 91 and the interior bottom of second clamp splice 92 laminate, the interior bottom of clamp splice and the laminating of second clamp splice 92, the top of clamp splice and the second clamp splice 92, and the top of two symmetrical bottom of well pipe laminates and forms the installation pipe 33 through the installation pipe 3 and the stability of the installation pipe mounting device of two semicircle pipes 82.
In the above embodiment, the locking members 32 are screws, and at least two locking members are provided on each clamping block 31. this has the advantage that the screws are universal and low cost, and two screw holes are provided on each clamping block 31, which corresponds to fastening devices 3 fixed by four screws, thus further improves the firmness and reliability of the fastening devices 3.
In the above embodiment, the middle tube 8 is installed in the installation tube 33, and the middle tube is fixed in a clamping manner, so that the reliability is greatly reduced, meanwhile, a gap must exist between the two clamping blocks 31, and the installation stability of the front support 1 and the rear single arm 2 is reduced, therefore, the installation and fixation of the middle tube 8 are ensured while the overall stability of the bicycle is ensured, in the embodiment, as shown in fig. 6-8, the bicycle further comprises a C-shaped gasket 34, the outer wall of the C-shaped gasket 34 is of a conical structure, the inner wall of the installation tube 33 is of a conical structure, the C-shaped gasket is arranged in the installation tube, and the middle tube 8 is inserted into the C-shaped gasket 34.
