According to an embodiment of the present disclosure, there is provided a handlebar and fork locking structure, as shown in fig. 1 to 7, the handlebar 1 and fork 2 locking structure including:
the handlebar vertical pipe comprises a handlebar vertical pipe 10, wherein a first plane 11 is arranged on the inner wall of one side of the bottom of the handlebar vertical pipe 10, and two first through holes 12 are coaxially arranged on the pipe wall of the handlebar vertical pipe 10.
The bicycle handlebar stand pipe comprises a front fork stand pipe 20, wherein a second plane is arranged on the outer wall of one side of the top of the front fork stand pipe 20, 21 two second through holes 22 are coaxially arranged on the pipe wall of the front fork stand pipe 20, the bottom of a handlebar stand pipe 10 is sleeved on the top of the front fork stand pipe 20, the first plane 11 abuts against the second plane 21, and the first through hole 12 is coaxial with the second through holes 22.
A fastener penetrating the first through hole 12 and the second through hole 22 to connect the handlebar stem 10 with the front fork stem 20.
In this embodiment, the first plane 11 on the inner wall of the handle stem 10 on the bottom side abuts against the second plane 21 on the outer wall of the front fork stem 20 on the top side, so as to form a locking structure in the circumferential direction of the front fork stem 20 and the handle stem 10, thereby effectively avoiding the problem of looseness between the front fork 2 and the handle 1, reducing the need for maintenance, and reducing the maintenance cost.
The handlebar stem 10 and the front fork stem 20 are both tubular structures. The handlebar stem 10 is sleeved on the front fork stem 20 and connected by a fastener. The two first through holes 12 and the two second through holes 22 are coaxially arranged, and the two second through holes 22 are located between the two first through holes 12. The fastener connects the handle stem 10 and the front fork stem 20 by penetrating the first through hole 12 and the second through hole 22.
The first plane 11 on the inner wall of the handle stem 10 abuts against the second plane 21 on the outer wall of the front fork stem 20, so that the handle stem 10 and the front fork stem 20 which are sleeved together can be limited to rotate in the circumferential direction.
For example, in the case of long-term use, the front fork 2 needs to be rotated by the handlebar 1 to complete the steering operation. The matching structure of the first plane 11 and the second plane 21 can limit the rotation of the handle stem 10 relative to the front fork stem 20, and effectively avoid the looseness between the handle bar 1 and the front fork 2. The firmness degree of the locking structure of the handlebar and the front fork is improved, and the maintenance cost is reduced.
In one embodiment, two first planes 11 are disposed on the inner wall of the handlebar stem 10 on the bottom side, and two second planes 21 are disposed on the outer wall of the front fork stem 20 on the top side, wherein the first planes 11 are in one-to-one correspondence with and abut against the second planes 21.
In this embodiment, the two first planes 11 correspond one-to-one to the two second planes 21 to form the restriction of the circumferential rotation at two positions. This can increase the restriction of the circumferential rotation, and further avoid the problem of the rotation of the handle stem 10 with respect to the front fork stem 20. The locking structure of the handlebar stem 10 and the front fork stem 20 is firmer, so that the repair required for loosening between the handlebar 1 and the front fork 2 is reduced, and the maintenance cost is reduced.
In one embodiment, as shown in fig. 2, 5, and 6, a locking groove 13 is formed on the handlebar stem 10, the locking groove 13 extends to the bottom of the handlebar stem 10, and the locking groove 13 is clear of the first through hole 12.
The handle stem 10 is sleeved on the front fork stem 20, and the handle stem 10 and the front fork stem 20 are connected together by a fastener. When the handle stem 10 is connected to the front fork stem 20 by the fastener, the fastener presses the handle stem 10 toward the front fork stem 20.
The locking groove 13 provides a gap to the handlebar stem 10 itself, and the locking groove 13 provides a compression space for the handlebar stem 10. The fastener can press the handle stem 10 to narrow the locking groove 13 to reduce the inner diameter of the handle stem 10. This enables the handlebar stem 10 to be more conformable to the front fork stem 20 to form a more firm connection structure.
Optionally, two locking grooves 13 are disposed on the handlebar stem 10, and the two locking grooves 13 are located at two axial sides of the first through hole 12.
In this embodiment, two locking grooves 13 are located at both sides of the first through hole 12 in the axial direction, so that the two locking grooves 13 are spaced apart from the two first through holes 12. When the fastening member is connected to the handlebar stem 10 and the front fork stem 20, the outer wall of the handlebar stem 10 is pressed from the positions of the two first through holes 12. The two locking grooves 13 can provide a space for the outer wall of the handlebar stem 10 to be capable of being squeezed at two axial sides of the first through hole 12, so that the outer wall of the handlebar stem 10 is uniformly deformed at two axial sides of the first through hole 12.
In one embodiment, as shown in fig. 3 and 6, two third planes 14 are disposed on the outer wall of the handlebar stem 10, and each of the first through holes 12 is located in one of the third planes 14.
In this embodiment, the third plane 14 provides a planar structure on the outer wall of the handlebar stem 10. After the fastening member is inserted into the first through hole 12, a limit is formed on the outer wall of the handlebar stem 10, so that the fastening member can be more easily matched with the outer wall of the handlebar stem 10, and the fastening effect of the fastening member is improved.
In one embodiment, as shown in fig. 2, the fastener comprises a bolt 15 and a nut 16, and the shaft of the bolt 15 penetrates the first through hole 12 and the second through hole 22 and is matched with the nut 16.
In this embodiment, the handlebar stem 10 is coupled to the front fork stem 20 by the bolt 15 and nut 16 mating. The bolt 15 and the nut 16 are simple in structure and low in cost. The two first through holes 12 and the two second through holes 22 are coaxially arranged to form a structure of a connection hole through which the bolt 15 penetrates. The head of the bolt 15 is restricted outside the outer wall on the side of one first through hole 12, and the shaft of the bolt 15 protrudes outside the outer wall on the side of the other first through hole 12 and engages with the nut 16.
For example, the head of the bolt 15 is located on one of the third planes 14, and the nut 16 is located on the other third plane 14.
In one embodiment, the nut 16 is fixed to the outer wall of the handlebar stem 10, and the nut 16 is located on the outer wall on the side of one of the first through holes 12, and is coaxially disposed with the first through hole.
In this embodiment, the nut 16 is fixed to the outer wall of the handlebar stem 10. When the bolt 15 is used for connection, the bolt 15 can be matched with the nut 16 only by penetrating the bolt 15 from the other first through hole 12 and rotating. This makes it easier to fit the bolt 15 and the nut 16, and reduces the difficulty in connecting the handle stem 10 to the front fork stem 20.
For example, the nut 16 is welded to the outer wall of the handlebar stem 10 on the side where one of the first through holes 12 is located.
In one embodiment, as shown in FIG. 2, the fastener further comprises a spring washer 17, wherein the spring washer 17 is sleeved on the shaft of the bolt 15 and is located between the head of the bolt 15 and the handlebar stem 10.
In this embodiment, the spring washer 17 is arranged at the head position of the bolt 15, and the spring washer 17 is arranged between the outer wall of the handlebar stem 10 and the head of the bolt 15, so that the structure of the bolt 15 matched with the nut 16 can be firmer.
For example, the spring washer 17 is located on a third plane 14. The bolt 15 is inserted from the first through hole 12 on the third plane 14.
