Detailed Description
To understand the embodiments of the present invention in more detail, please refer to the accompanying drawings, as shown in fig. 1 to 11, which are a structure for adjusting the offset of a front fork of a bicycle, and are disposed at the end of a shoulder arm 11 of a front fork 1, and the structure includes: a hook 2, which is formed by connecting a base 21 to the shoulder arm 11 of the front fork 1 and bending and extending a deviation portion 22, wherein the base 21 and the deviation portion 22 are recessed on the same side so that the hook 2 forms a containing groove 23, the containing groove 23 has a groove opening 234, a first hole 211 communicating with the containing groove 23 is arranged on one side of the base 21 away from the groove opening 234, and a second hole 221 communicating with the containing groove 23 is arranged on one side of the deviation portion 22 away from the groove opening 234; and an offset adjusting block 3 movably disposed in the accommodating cavity 23, wherein a shaft hole 311 penetrates through the offset adjusting block 3, and the offset adjusting block 3 has a first offset state in which the shaft hole 311 corresponds to the first hole 211 and is disposed in the accommodating cavity 23; and the shaft hole 311 corresponds to the second hole 221 and is disposed in the second offset state of the receiving groove 23.
The shaft hole 311 is used for assembling the wheel 8.
The hook 2 of the present invention has different amounts according to different types of front forks, for example, the front fork of the single shoulder arm only has one hook 2 with one deflection adjusting block 3, the front fork 1 of the dual shoulder arm 11 has two hook 2 with two deflection adjusting blocks 3, and the embodiment is exemplified by the front fork 1 of the dual shoulder arm 11.
As shown in fig. 5, 6 and 12, the axle hole 311 of the offset adjustment block 3 corresponds to the first offset state (offset)65 of the first hole 211, and if the offset of the front fork 1 is to be adjusted, the wheel 8 is removed, the offset adjustment block 3 is removed from the receiving groove 23, the offset adjustment block 3 is rotated as shown in fig. 8 until the axle hole 311 is installed back to the receiving groove 23 after the second hole 221, and then the axle hole 311 is switched to the second offset state (offset)44 of the axle hole 311 corresponding to the second hole 221, and the wheel 8 is installed back to the axle hole 311, as shown in fig. 9, 10, 11 and 13, to complete the adjustment of the front fork offset, and by combining the above contents, the front fork of the present invention can be adjusted without actually replacing the entire set of front fork 1, it can be said that the existing problems are thoroughly improved.
As shown in fig. 1 to 13, the misalignment adjusting block 3 includes a connecting portion 31 and a shielding portion 35 connected to each other, the shaft hole 311 is located in the connecting portion 31, wherein when the misalignment adjusting block 3 is in the first misalignment state, the shielding portion 35 shields the outside of the second hole 221, and when the misalignment adjusting block 3 is in the second misalignment state, the shielding portion 35 shields the outside of the first hole 211, which is advantageous in that the shielding portion 35 can shield the holes that cannot be used, so as to prevent the holes 8 from being mistakenly installed when the wheel is installed, thereby having the fool-proof effect and preventing dust from entering the wheel hub through the holes that cannot be used.
As shown in fig. 1 to 13, the receiving slot 23 is elongated, and the offset adjustment block 3 is elongated corresponding to the receiving slot 23, and the shaft hole 31 has to correspond to the first hole 211 or the second hole 221 precisely, so as to avoid affecting the installation of the wheel 8.
The present invention is shown in fig. 2, fig. 3, fig. 5, and fig. 11, wherein the hook 2 has a through hole 24, the through hole 24 is located between the first hole 211 and the second hole 221, a connecting hole 32 is recessed toward one side of the accommodating groove 23 of the deviation adjusting block 3, another connecting member 4 is further provided, the connecting member 4 has a head portion 41 and a body portion 42 connected to each other, the body portion 42 movably penetrates through the through hole 24 and is movably connected to the connecting hole 32, the head portion 41 abuts against the outside of the hook 2, in this embodiment, the connecting member 4 is a screw, and with this structure, the deviation adjusting block 3 can be stably positioned in the accommodating groove 23, and it is very fast and convenient to disassemble the deviation adjusting block 3.
As shown in fig. 6 and 11, the receiving cavity 23 includes a straight section 231 and a tapered section 232 connected in a ring shape, the straight section 231 is connected to the cavity opening 234, the inner wall of the tapered section 232 is tapered from the portion connected to the straight section 231 to the direction away from the cavity opening 234, the shape of the offset adjusting block 3 corresponds to the receiving cavity 23, the portion of the offset adjusting block 3 abutting against the tapered section 232 has an inclined cone 33, the portion of the offset adjusting block 3 abutting against the straight section 231 has a straight surface 34, the straight surface 34 is connected to the inclined cone 33, since the offset adjusting block 3 is the portion that must be assembled with the wheel 8, the offset adjusting block 3 should not shake relative to the receiving cavity 23 during the vehicle traveling, so that the offset adjusting block 3 must be designed to be relatively flat and flat, if the inner wall of the receiving cavity 23 is completely flat, the offset adjusting block 3 is difficult to be placed in the receiving groove 23, and the structure of the embodiment is advantageous in that the tapered portion of the offset adjusting block 3 guides the inclined conical surface 33 by the tapered section 232, so that the offset adjusting block 3 is more easily placed in the receiving groove 23.
As shown in fig. 5 and 9, further comprising a caliper support bracket 5 movably connected to the front fork shoulder arm 11 and facing the same side as the offset portion 22, the caliper support bracket 5 is provided for adjusting the position of the caliper 6 since the offset of the front fork is changed to make it possible to offset the caliper 6 from the disc 7.
The above description is only a preferred embodiment of the present invention, and is not intended to limit the present invention in any way, and all simple modifications, equivalent changes and modifications made by the technical spirit of the present invention to the above embodiments still fall within the scope of the technical solution of the present invention.
