Detailed Description

In the following description, numerous specific details are set forth in order to provide a more thorough understanding of the present invention. It will be apparent, however, to one skilled in the art, that the present invention may be practiced without one or more of these specific details. In other instances, well-known features have not been described in order to avoid obscuring the present invention.

In order to enable the bicycle front fork to have a good shock absorption effect, as shown in fig. 1 and 2, a stroke tube 11 is connected in each of two outer tubes 1 in a sliding manner, a fork bridge 19 is fixedly welded between the two outer tubes 1, a positioning block 2 is fixedly connected to the surface of the stroke tube 11, a supporting column 12 is fixedly connected to the bottom wall of an inner cavity of the outer tube 1, a first strong magnet 13 is fixedly connected to the top of the supporting column 12, a buffer spring 14 is placed in the outer tube 1, a connecting column 15 is fixedly connected to the top wall of the inner cavity of the stroke tube 11, a second strong magnet 16 is fixedly connected to the bottom of the connecting column 15, the magnetism of opposite surfaces of the first strong magnet 13 and the second strong magnet 16 is the same, the first strong magnet 13 and the second strong magnet 16 can repel each other, when the bicycle is subjected to shock absorption, the stroke tube 11 slides in the outer tube 1, the stroke tube 11 extrudes the buffer spring 14, and the first strong magnet 13 and the second strong magnet 16 repel each other, reduce 11 decurrent impact forces of stroke pipe to reach absorbing work purpose, make things convenient for stroke pipe 11 to reset simultaneously after the shock attenuation, the lower half outer wall fixedly connected with spacing ring 18 of stroke pipe 11, and the guide way 17 that supplies spacing ring 18 to remove is seted up to the inner wall of outer tube 1, avoids stroke pipe 11 slippage from outer tube 1.

In order to adjust the height of the handlebar according to the height and the use habit of a user and ensure the stability of the bicycle in the turning process, as shown in fig. 1, fig. 2 and fig. 4, a support sleeve 21 is welded and fixed on the surface of a positioning block 2, an adjusting column 22 is slidably connected in the support sleeve 21, a handle is installed at the top of the adjusting column 22, an adjusting ring 23 is sleeved on the outer wall of the lower half part of the support sleeve 21, a connecting block 25 is fixedly connected between the adjusting column 22 and the adjusting ring 23, moving grooves 24 for the connecting block 25 to move are formed in the outer walls of the two sides of the support sleeve 21, the height of the adjusting column 22 can be adjusted by adjusting the position of the adjusting ring 23 outside the support sleeve 21, so that the handle is adjusted to a proper height according to the use habit of the user, thereby ensuring that the user has a better riding experience, a threaded hole is formed in the outer wall of one side of the adjusting ring 23, and a fixing bolt 26 is screwed into the threaded hole of the adjusting ring 23, and the position of the adjusting ring 23 is fixed by tightening the fixing bolt 26.

The first outer wall of supporting sleeve 21 rotates through the bearing and is connected with fixed block 3, fixed block 3 and frame welded fastening, one side outer wall welded fastening of fixed block 3 has connecting plate 31, one side outer wall that fixed block 3 was kept away from to connecting plate 31 has storage basket 32 through the bolt fastening, when the bicycle turned, the handle drove supporting sleeve 21 through adjusting post 22 and rotates, supporting sleeve 21 takes place to rotate for fixed block 3, avoid storage basket 32 to take place to rotate with the wheel simultaneously, avoid storage basket 32's weight direct action on the front wheel, thereby guarantee the stability of bicycle turn in-process.

The working principle is as follows:

when the reinforced loading bicycle front fork is used, the bicycle front fork and a frame are installed, the position of the adjusting ring 23 outside the supporting sleeve 21 is adjusted, the height of the adjusting column 22 is adjusted, the handle is adjusted to a proper height according to the use habit of a user, and then the fixing bolt 26 is screwed down, so that the position of the adjusting ring 23 is fixed;

when the in-process that the bicycle went produced vibrations, stroke pipe 11 slides in outer tube 1, stroke pipe 11 extrudees buffer spring 14, strong magnet 13 and two 16 mutual repulsion of strong magnet simultaneously, reduce the decurrent impact force of stroke pipe 11, thereby reach absorbing work purpose, when the bicycle turns, the handle drives the support sleeve 21 through adjusting post 22 and rotates, thereby adjust the angle of front wheel, support sleeve 21 takes place to rotate for fixed block 3, avoid storing basket 32 to take place to rotate with the wheel simultaneously, avoid storing basket 32's weight direct action on the front wheel, thereby guarantee the stability of bicycle turning in-process.

Finally, it should be noted that: the foregoing is merely a preferred embodiment of the present invention and is not intended to limit the scope of the invention.
