Detailed description of the invention
Below in conjunction with drawings and Examples, the invention will be further described.
As shown in Figure 1, the identical apparatus of the present invention of structure are housed in the both sides of bicycle rear main shaft, apparatus of the present invention comprise ten hexagon adapter shaft 8, ten hexagon locating bushs 6, orienting sleeve 5, toe board 1, right connecting panel 2 and left connecting panel 3; Ten hexagon adapter shaft 8 overcoats have ten centers, hexagon locating bush 6, ten hexagon adapter shaft 8 one end to be provided with axle internal thread hole 10, and axle internal thread hole 10 connects bicycle rear main shaft, as shown in Figure 5; Ten hexagon locating bushs 6 are stepped shaft, as shown in Figure 6, small end is near the side of axle internal thread hole 10, and large side wall has external threading hole 11, and external threading hole 11 is built with the positioning threads latch 9 for being fixedly connected with ten hexagon locating bushs 6 by ten hexagon adapter shafts 8; As shown in Figure 7 and Figure 8, the large end top of ten hexagon locating bushs 6 is fixed with limiting stopper 7, and on the small end of ten hexagon locating bushs 6, cover has orienting sleeve 5, and orienting sleeve 5 connects toe board 1 by back flap hinge fitting, and during use, toe board 1 is placed on limiting stopper 7.
As shown in figures 1 and 3, ten hexagon adapter shaft 8 outer peripheral faces and ten hexagon locating bush 6 inner peripheral surfaces are ten hexagon posts and cooperatively interact and are set with.
As shown in Figure 1 to 4, back flap hinge fitting comprises projection, right connecting panel 2 and the left connecting panel 3 that orienting sleeve 5 side is fixed with, the both sides of projection are hinged with right connecting panel 2, left connecting panel 3 respectively by connection rotating shaft 4, and left connecting panel 3 is all fixedly connected with toe board 1 with right connecting panel 2.
As shown in Figures 2 and 3, positioning threads latch 9 is tightened through external threading hole 11 lateral wall being connected to ten hexagon adapter shafts 8, makes to interfix between ten hexagon adapter shafts 8 and ten hexagon locating bushs 6.
Specific embodiment of the invention working process is as follows:
Ten hexagon adapter shaft 8 one end are installed on the main shaft of bicycle rear by ten hexagon adapter shaft internal thread holes 10, the axle horizontal direction of ten hexagon locating bush 6 small ends along ten hexagon adapter shafts 8 is installed, during installation, limiting stopper 7 position of ten hexagon locating bushs 6 as far as possible upward, limiting stopper 7 can ensure that toe board 1 keeps level attitude as far as possible, ten hexagon locating bushs 6 are fixed on ten hexagon adapter shafts 8 by ten hexagon locating bush tapped bore 11 by positioning threads latch 9, orienting sleeve 5 can rotate around ten hexagon locating bush 6 main shafts, toe board 1 is connected to left connecting panel 3 and right connecting panel 2, toe board 1 can do an angle of 90 degrees degree around connection rotating shaft 4 and rotate.
During normal use, directly over orienting sleeve 5 raised position rotates to, toe board 1 forwards level attitude to around connection rotating shaft 4, toe board 1 is near on the upside of limiting stopper 7, orienting sleeve 5 does according to limiting stopper 7 actual position and rotates adjustment, and drive toe board 1 to rotate, toe board 1 and limiting stopper 7 are fully fitted.
