[0001] The utility model belongs to the technical field of bicycles, and more specifically, it particularly relates to a front-end mechanism of a bicycle with quick combination. Background Art

[0002] The assembly process of a bicycle is quite complex and requires a variety of professional tools. For non-professionals or those who are not skilled, this can be a time-consuming and laborious process; in addition, the assembly process of a traditional bicycle requires various professional tools, and multiple complex adjustment steps are also required to correctly assemble the bicycle.

[0003] The existing publication number CN221340934U discloses a front-end mechanism of a bicycle with quick combination. Although it simplifies the structures of the handlebar riser group, the headset group, and the front fork group, and when the handlebar riser group and the headset group are sleeved on the front fork group, through the mutual clamping of the positioning blocks and the front fork group, the assembly of the handlebar riser group, the headset group, and the front fork group is completed while having a guiding effect; therefore, it improves the complexity of requiring professional tools when assembling the front-end mechanism of a traditional bicycle, as well as the problems of requiring calibration and adjustment.

[0004] Based on the above, the inventor found the following problems: However, the structure of this front-end mechanism is still too complex and the material cost is relatively high, resulting in the need for long-term training of the installation workers during installation, increasing the labor cost at the same time. Also, there will be a relatively high error rate during installation, resulting in the front-end mechanism being unable to be used normally after installation.

[0005] Therefore, in view of this, research and improvement are carried out on the existing structure and deficiencies, and a front-end mechanism of a bicycle with quick combination is provided, in order to achieve a more practical and valuable purpose. Summary of the Utility Model

A limiting ring is fixedly installed at the top of the outer wall of the second sleeve rod, and a limiting block for plugging and matching with the limiting hole is fixedly installed at the top of the outer side wall of the elastic rod. Bearings are fixedly installed at the bottom of the second sleeve rod and the top of the first sleeve rod. Hub connecting rods are fixedly installed on both sides at the bottom end of the second sleeve rod, and a connecting hole is penetrated and opened at the bottom of one side of the hub connecting rod.

A plurality of the limiting blocks are provided, and the plurality of limiting blocks are arranged in one-to-one correspondence with the plurality of limiting holes. A first arc-shaped groove is opened on the outer wall of the limiting block.

[0011] Further, a screwdriver blade opening is opened at the top of the rotating block, an external thread is arranged on the outer wall of the rotating block, and an internal thread is arranged at the top of the inner wall of the first sleeve rod, and the internal thread and the external thread are used in a matching manner.

[0025] Embodiment:

[0026] As shown in the attached Figure 1 to the attached Figure 4 shown:

[0027] The utility model provides a bicycle front-end mechanism with quick combination, including a first sleeve rod 1 and a second sleeve rod 2, characterized in that: a handle connecting block 5 is fixedly installed at the top of the first sleeve rod 1, a limiting hole 11 is penetrated and opened on the outer wall of the middle part of the first sleeve rod 1, a rotating block 3 is threadedly connected to the top inside the first sleeve rod 1, a frustum-shaped extrusion block 33 is fixed at the bottom of the rotating block 3, an elastic rod 22 extending into the first sleeve rod 1 is fixed at the top of the second sleeve rod 2. In the natural state, the inner diameter of the elastic rod 22 is larger than the maximum diameter of the extrusion block 33. A limiting ring 21 is fixedly installed at the top of the outer wall of the second sleeve rod 2, and a limiting block 23 for plugging and matching with the limiting hole 11 is fixed at the top of the outer side wall of the elastic rod 22. Bearings 4 are fixed at the bottom of the second sleeve rod 2 and the top of the first sleeve rod 1 respectively. Hub connecting rods 6 are fixed at both sides of the bottom end of the second sleeve rod 2, and a connecting hole 61 is penetrated and opened at the bottom of one side of the hub connecting rod 6.

[0028] Wherein, the inner diameter value of the first sleeve rod 1 is adapted to the outer diameter value of the second sleeve rod 2. The first sleeve rod 1 and the second sleeve rod 2 are respectively inserted from the top and bottom of the connecting hole at the front end of the vehicle frame, and at the same time, the second sleeve rod 2 can be inserted into the first sleeve rod 1.

[0029] Wherein, a plurality of limiting holes 11 are provided, and the plurality of limiting holes 11 are arranged at equal circumferential intervals. A plurality of limiting blocks 23 are provided, and the plurality of limiting blocks 23 are arranged in one-to-one correspondence with the plurality of limiting holes 11. A first arc-shaped groove 24 is opened on the outer wall of the limiting block 23. When the second sleeve rod 2 enters the first sleeve rod 1, when the first sleeve rod 1 touches the limiting ring 21, at this time, the limiting block 23 and the limiting hole 11 are on the same horizontal plane. By rotating the first sleeve rod 1 and the second sleeve rod 2 to rotate the limiting block 23 into the limiting hole 11, the opened first arc-shaped groove 24 enables the elastic rod 22 to contract towards the inside of the second sleeve rod 2 when the second sleeve rod 2 enters the first sleeve rod 1. After the limiting block 23 is aligned with the limiting hole 11, the elastic rod 22 releases elastic potential energy to pop the limiting block 23 into the limiting hole 11.

[0030] Wherein, a screwdriver blade opening 31 is opened at the top of the rotating block 3, an external thread 32 is arranged on the outer wall of the rotating block 3, an internal thread 12 is arranged at the top of the inner wall of the first sleeve rod 1, and the internal thread 12 and the external thread 32 are used in combination. By using a screwdriver to align with the screwdriver blade opening 31 and rotate, the rotating block 3 rotates inside the first sleeve rod 1, driving the extrusion block 33 to move downward.

[0031] Wherein, the maximum diameter value of the extrusion block 33 is smaller than the inner diameter value of the first sleeve rod 1, and the frustum-shaped extrusion block 33 can better extrude one side of the inner wall of the elastic rod 22.

[0032] Among them, a through hole 51 is opened through the bottom end of the handle connecting block 5, and the central axis of the through hole 51 and the central axis of the rotating block 3 are arranged in a colinear manner, so that the connecting block 5 can be directly formed during welding production in advance, and can be installed through the through hole 51 during installation.

[0033] Among them, the outer walls of the two bearings 4 on the opposite side are each provided with a second arc groove 41. The second arc groove 41 allows the bearing 4 to better enter the connecting hole at the front end of the frame, and the first set of rods 1 and the second set of rods 2 are supported by the bearings 4, so that when the handle is turned to drive the handle connecting block 5 to rotate, the first set of rods 1 and the second set of rods 2 will not rub against the front end of the frame.

[0034] The specific usage and function of this embodiment are as follows:

[0035] In the present invention, the first set of rods 1 and the second set of rods 2 are firstly inserted from the top and bottom of the connection hole at the front end of the frame, respectively, and the second set of rods 2 can be inserted into the first set of rods 1 at the same time. When the first set of rods 1 touches the limiting ring 21, the limiting block 23 and the limiting hole 11 are located at the same horizontal plane. The limiting block 23 is rotated into the limiting hole 11 by rotating the first set of rods 1 and the second set of rods 2. The first arc groove 24 is provided so that when the second set of rods 2 enters the first set of rods 1, the elastic rod 22 contracts toward the inside of the second set of rods 2. After the limiting block 23 is aligned with the limiting hole 11, the elastic rod 22 releases the elastic potential energy to bounce the limiting block 23 into The limiting hole 11 is then rotated by aligning a screwdriver with the screwdriver blade 31, and the rotating block 3 is rotated inside the first set of rods 1, driving the extrusion block 33 to move downward. The truncated cone-shaped extrusion block 33 can better squeeze one side of the inner wall of the elastic rod 22, limit the elastic rod 22 and the limiting block 23, and prevent the elastic rod 22 from jumping during riding. The second arc groove 41 is set so that the bearing 4 can better enter the connecting hole at the front end of the frame, and the first set of rods 1 and the second set of rods 2 are supported by the bearing 4, so that when the handlebar is turned to drive the handlebar connecting block 5 to rotate during riding, the first set of rods 1 and the second set of rods 2 will not rub against the front end of the frame.

[0036] The embodiments of the present invention are provided for the purpose of illustration and description, and are not intended to be exhaustive or to limit the present invention to the disclosed forms. Many modifications and variations will be apparent to those of ordinary skill in the art.
