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.

In the embodiment, the taper of the C-washer 34 is the same as the taper of the mounting tube 33.

In the embodiment, the inner wall of middle tube 8 and the outer wall of C-shaped washer 34 are respectively provided with transverse lines 35, which increase the friction between middle tube 8 and C-shaped washer 34.

The C-shaped washer 34 may be deformed to be unable to return to its original state when it is used for a long time, so that it is difficult to separate from the middle tube 8. an expansion block 35 is further provided in the installation tube 33, wherein the expansion block 35 only needs to be installed on of the clamping blocks 31. specifically, the expansion block 35 includes a guide portion 351 and an expansion portion 352. the expansion portion 351 has a triangular shape, and a width thereof is larger than a width of a notch when the C-shaped washer 34 is locked and smaller than a width of the notch when the C-shaped washer is released, and the guide portion 351 has a rectangular structure, and when the C-shaped washer 34 is locked, the guide portion 351 is located in the middle of the notch of the C-shaped washer 34, and when the C-shaped washer is released, the middle tube 8 is lifted up, the C-shaped washer 34 is guided by both side edges of the expansion portion 352.

The utility model discloses when using, as shown in fig. 1-8, cooperate the installation with the clamp splice 31 of fore-stock 1 and back single armed 2 for half round pipe 311 makes up the installation pipe 33 that forms well pipe 8 in the installation, sets up C shape packing ring 34 in installation pipe 33, well pipe 8 inserts in the C shape packing ring 34, through pushing down well pipe 8, can realize well locking of pipe 8. When the height of the middle pipe 8 is adjusted, the middle pipe 8 is lifted upwards, and after the height is adjusted, the middle pipe is pressed downwards again and locked. When the bicycle needs to be dismantled for storage, the locking piece 32 only needs to be loosened, and the two clamping blocks 31 are separated.

The above are only preferred embodiments of the present invention, and are not intended to limit the scope of the present invention; the scope of the appended claims should be accorded the broadest interpretation so as to encompass all such modifications and equivalent arrangements as is within the spirit and scope of the present invention.
