[0028] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention will be further described in detail below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0029] In this embodiment, the direction of the fixing frame on the horizontal plane is used as the reference direction for the up and down directions.

[0030] like Figure 1-Figure 3 As shown, a bicycle fixing frame includes a base 10, a rear fork fixing member 20 and a front fork fixing mechanism.

[0031] The front fork fixing mechanism includes a moving rod 31, a rotating device and a front fork fixing member 32. The rotating device includes a connecting block 41, a rotating ring 42, a circular rotating bead 43 and a rotating rod 44. One end of the moving rod 31 is detachably connected to the base 10, and the other end of the moving rod 31 is fixedly connected to the lower end of the connecting block 41. In this embodiment, the base 10 is rectangular, and a connecting portion 11 is provided on the base 10 that is parallel to the length direction of the base 10. A moving groove 311 is provided on the moving rod 31 and arranged along the length direction of the moving rod. A connecting groove 111 is provided on the connecting portion 11, and a through hole connected to the connecting groove 111 is provided on the base 10. The moving rod 31 passes through the through hole and the connecting portion in sequence, and the connecting groove 111 corresponds to the movable groove 311, and the movable rod 31 is fixedly connected to the connecting part 11 through a second fixing member. By setting the movable groove 311 on the movable rod 31, the position of the movable rod 31 connected to the base 10 can be adjusted according to actual usage requirements to adapt to different bicycle fixing requirements; in the present embodiment, the second fixing member includes a block a1 that can be extended into the connecting groove 111 and the movable groove 311 and a second limit block a2 threadedly connected to the block a1. The outer diameter or width of the second limit block a2 is greater than the width of the connecting groove 111. The movable rod 31 is fixed to the base 10 by rotating the second limit block a2. The second fixing member can also be matched with a conventional screw and nut.

[0032] The rotating ring 42 is fixedly connected to the end of the connecting block 41 away from the moving rod 31 through a first fixing member. The connecting block 41 has a rotating groove 411 on the end away from the moving rod 31. The rotating groove 411 is located in the rotating ring 42. The circular rotating bead 43 is partially located in the rotating groove 411 and the circular rotating bead 43 partially extends above the rotating ring 42. One end of the rotating rod 44 is connected to the position where the circular rotating bead 43 is located outside the rotating ring 42. The other end of the rotating rod 44 is connected to the middle position of the length direction of the front fork fixing member. When the first fixing member is loosened, the circular rotating bead 43 can rotate in the rotating ring 42.

[0033] In this embodiment, a movable groove 421 is provided on the inner wall of the rotating ring 42 corresponding to a position close to the connecting block 41, and at least two connecting strips 412 are provided on the connecting block 41. Each connecting strip 412 is inserted into the movable groove 421. The width of the movable groove 421 is greater than the thickness of the connecting strip 412, so that when the first fixing member is loosened, the rotating ring 42 can move up and down, and the inner diameter of the upper end of the rotating ring 42 is smaller than the diameter of the circular rotating bead 43, so that the circular rotating bead 43 can be confined in the rotating ring 42.

[0034] In this embodiment, a threaded hole is provided on the rotating ring 42, and the first fixing member has an external thread section that matches the threaded hole, and one end of the first fixing member is pressed against the outer wall of the rotating groove 411. The first fixing member is connected to the rotating ring 42 by threaded cooperation. The cross-section of the rotating groove 411 is circular, and the outer diameter and inner diameter of the rotating groove 411 gradually increase from one end close to the moving rod 31 to the other end, so that the outer wall of the rotating groove 411 is arranged inclined, and the first fixing member is pressed against the outer wall of the rotating groove 411. When the first fixing member is gradually tightened, the rotating ring 42 gradually moves downward under the drive of the first fixing member. Since the inner diameter of the upper end of the rotating ring 42 is smaller than the outer diameter of the circular rotating bead 43, the circular rotating bead 43 is fixed, and then the front fork fixing member 32 is fixed.

[0035] A fixed platform 422 is provided on the rotating ring 42. The fixed platform 422 is arranged to be inclined gradually from one end close to the connecting block 41 to the other end toward the direction of the circular rotating bead 43. The fixed platform 422 abuts against the circular rotating bead 43, and a gradually shrinking fixed surface is formed by the fixed platform 422, so that the circular rotating bead 43 can be better restricted, thereby preventing the front fork of the bicycle from shaking after being fixed.

[0036] The rear fork fixing member 20 is integrally connected or welded to the base 10, and the rear fork fixing member 20 is arranged opposite to the front fork fixing member 32. The rear fork fixing member 20 is gradually inclined toward the front fork fixing member 32 from one end close to the base 10 to the other end. The front fork fixing member 32 is used to fix the front fork of the bicycle, and the rear fork fixing member 20 is used to fix the rear fork of the bicycle. In this embodiment, a reinforcement portion 12 is further connected to the base 10, and one end of the connecting portion 11 away from the front fork fixing member 32 is connected to the reinforcement portion 12. The reinforcement portion 12 and the connecting portion 11 are arranged perpendicular to each other. The stability of the fixing frame is increased by providing the reinforcement portion 12. The distance between the reinforcement portion 12 and the front fork fixing member 32 is greater than the distance between the reinforcement portion 12 and the rear fork fixing member 20, so that when the bicycle is fixed to the fixing frame, components such as the pressure plate or rear derailleur of the bicycle will not be restricted or rubbed by the reinforcement portion 12.

[0037] As a preferred embodiment of this embodiment, a positioning hole 423 is provided on the end of the rotating ring 42 away from the connecting block 41, and the rotating rod 44 is clamped in the positioning hole 423. By clamping the rotating rod 44 in 423, the front fork fixing member 32 is made more stable, and the rotation angle of the rotating rod 44 is also larger to adapt to the fixing requirements of different bicycles.

[0038] The fixing frame is used as follows: the movable rod 31 is moved to a position suitable for the length of the bicycle and fixed by the second fixing member. The front fork and rear fork of the bicycle are pre-tightened on the front fork fixing member 32 and the rear fork fixing member 20 respectively, but cannot be completely locked to prevent the front fork of the bicycle from deforming during rotation, and the first fixing member is loosened or pulled away from the rotating ring 42 so that the circular rotating ball 43 can rotate in the rotating groove 411, thereby driving the rotating rod 44 and the front fork fixing member 32 to rotate. When the front fork of the bicycle is rotated to the desired angle, that is, after the bicycle handlebar is rotated to be parallel to the length direction of the base 10, the first fixing member is rotated so that the rotating ring 42 fixes the circular rotating ball 43. Finally, the front fork and the rear fork of the bicycle are locked to the corresponding fixing members. At this time, the side of the handlebar away from the front fork, that is, the front side of the handlebar is located inside the base 10. The handlebar does not protrude from the inside of the base 10, which can reduce the probability of the handlebar being hit during transportation, thereby reducing the probability of damage to the bicycle.

[0039] To sum up, the present application connects the front fork fixing part 32 to the rotating rod 44, the rotating rod 44 is connected to the circular rotating bead 43, the circular rotating bead 43 can rotate in the rotating groove 411, and is limited by the rotating ring 42, so that the front fork fixing part can be rotated as needed, and the bicycle handlebar can be rotated to one side of the bicycle front fork, avoiding the bicycle bag protruding on both sides of the bicycle handlebar, reducing the packaging volume, and saving transportation costs.

[0040] The specific implementation methods described above further illustrate the purpose, technical solutions and beneficial effects of the utility model in detail. It should be understood that the above description is only a specific implementation method of the utility model and is not intended to limit the scope of protection of the utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the utility model should be included in the scope of protection of the utility model.
