DETAILED DESCRIPTION
[0014] The present invention is further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention. See also Figures 3 to 7, a buckle-type quick release 20, comprising: an axle rod 21, which is configured as a hollow round rod body so that it has a rod through hole 22 inside, one end of the rod through hole 22 is provided with a first end inner thread segment 221, and the other end is provided with a second end inner thread segment 222, and the side end of the axle rod 21 and the second end inner thread segment 222 is provided with an axial end edge 211; an adjustment rod 23 with an outer thread segment 231, one end of the adjustment rod 23 is provided with a buckle end 232 that can be clamped externally, and the buckle end 232 is provided with a driving hole 233 open to the outside, and the outer thread segment 231 of the adjustment rod 23 is provided with a buckle end 232 that can be clamped externally. 31 is screwed into the first end inner thread segment 221 of the rod through hole 22; a movable sleeve 24 is provided with a sleeve groove 25 inside, so that one end of the movable sleeve 24 forms an opening 241, and the other end is provided with a through hole 26 connected to the sleeve groove 25, the inner diameter of the sleeve groove 25 is larger than the inner diameter of the through hole 26, so that there is a difference edge 27 between the sleeve groove 25 and the through hole 26; and an annular spring 28 is inserted into the sleeve groove 25, and the sleeve groove 25 of the movable sleeve 24 is fitted through the opening 241 on the end of the shaft rod 21 different from the adjustment rod 23, so that one end of the annular spring 28 abuts against the shaft rod 2 1, and the other end thereof abuts against the step edge 27 of the movable sleeve 24; and an eccentric locking assembly 30, which has a quick-release handle 31 that can be eccentrically turned and a locking rod 32 that can be screwed on the inner thread segment 222 of the second end, wherein the locking rod 32 is provided with an outer thread segment 321 at a periphery relatively far from the eccentric locking assembly 30, and a sliding segment 322 at a periphery relatively close to the eccentric locking assembly 30, and a stop flange 323 is provided between the outer thread segment 321 of the locking rod 32 and the sliding segment 322, so that the outer thread segment 321 of the locking rod 32 passes through the movable sleeve 24. The through hole 26 and the annular spring 28 of the movable sleeve 24 are screwed into the second end inner thread segment 222 of the rod through hole 22, and the annular spring 28 is compressed at the same time. At least one side hole 212 is provided on the periphery of the shaft rod 21 at the position corresponding to the sliding segment 322, and connected to the rod through hole 22. A latch member 33 is assembled in the side hole 212 to protrude from the rod through hole 22, and a stop flange 323 of the screw rotation displacement can abut against the edge of the latch member 33, so that the locking rod 32 slides within the range of the sliding segment 322. By means of the above, the buckle-type quick release 20 can adjust the length in both directions to achieve a wider adjustment effect.
[0015] The composition, function and efficacy of the present invention are described in detail as follows: Figures 3 to 8The latch member 33 of the present invention is a countersunk screw, and the side hole 212 is a screw hole with an internal thread. The latch member 33 is screwed into the side hole 212 so that the latch member 33 protrudes from the rod through hole 22 but does not press on the sliding section 322 to avoid hindering the rotation of the locking rod 32, and the stop flange 323 prevents the locking rod 32 from accidentally disengaging from the shaft 21. Furthermore, the locking torque between the first end inner thread segment 221 and the adjusting rod 23 of the present invention is greater than the locking torque between the second end inner thread segment 222 and the locking rod 32. Its function is that when the buckle-type quick release 20 is assembled with the frame 1, the drive hole 233 of the adjusting rod 23 can be inserted into the wrench tool 2 to twist the drive hole 233, so that the shaft rod 21 and the adjusting rod 23 do not rotate relative to each other, but the shaft rod 21 and the locking rod 32 rotate relative to each other. In other words, the adjustment rod 23 is driven to rotate by the wrench tool 2 to adjust the screwing position of the locking rod 32 and change the length of the buckle-type quick release 20; please refer to Figure 8 As shown, the present invention sets the locking torque by coating an anti-loosening coating 29 (for example, using anti-falling rubber coating) on the outer thread segment 231 of the adjustment rod 23. The area and thickness of the anti-loosening coating 29 can be used to change different locking torque settings, so that the adjustment rod 23 increases its friction, thereby preventing loosening or disengagement, and preventing water from penetrating. When the length of the buckle-type quick release 20 is to be adjusted, first, the user holds the shaft 21, fits the drive hole 233 of the adjustment rod 23 with the wrench tool 2, and turns the adjustment rod 23 to make it rotate relative to the shaft 21 (such as Figure 6 As shown in the figure, if the adjusting rod 23 is driven to rotate clockwise, the adjusting rod 23 is screwed into the first end inner thread segment 221 to shorten the length of the buckle type quick release 20. If the adjusting rod 23 is driven to rotate counterclockwise, the adjusting rod 23 is screwed out of the first end inner thread segment 221 to increase the length of the buckle type quick release 20. In order to prevent the shaft rod 21 from deviating excessively from one side, the user then holds the quick release handle 31 and fits the driving hole 233 of the adjusting rod 23 with the wrench tool 2. Since the anti-loosening coating 29 is coated on the outer thread segment 231 of the adjusting rod 23 to increase the locking torque, when the wrench tool 2 is turned, the adjusting rod 23 rotates synchronously with the shaft rod 21, so that the shaft rod 21 and the locking rod 32 rotate relative to each other (as shown in the figure). Figure 7As shown in the figure, if the shaft 21 is driven to rotate clockwise, the locking rod 32 is screwed into the second end inner thread segment 222 to shorten the length of the buckle type quick release 20, and at the same time, the eccentric locking assembly 30 presses against the movable sleeve 24 and the annular spring 28 to displace the movable sleeve 24 toward the shaft 21; if the shaft 21 is driven to rotate counterclockwise, the locking rod 32 is screwed out of the second end inner thread segment 222 to increase the length of the buckle type quick release 20, and at the same time, the annular spring 28 elastically restores and supports the movable sleeve 24 and the eccentric locking assembly 30 to displace the movable sleeve 24 away from the shaft 21, so that the movable sleeve 24 and the eccentric locking assembly 30 are kept without a gap; in this way, the two ends of the shaft 21 of the buckle type quick release 20 can be evenly shortened or lengthened. After adjusting the length through the above steps, the bicycle can be assembled on the bicycle frame 1 to fix the wheel axle. After assembly, if it is found that the buckle-type quick release 20 does not completely match the use length of the bicycle frame 1, the user can insert the wrench tool 2 into the driving hole 233 of the adjustment rod 23 outside the bicycle frame 1 to turn the adjustment rod 23, so that the shaft rod 21 and the locking rod 32 can rotate relative to each other, thereby fine-tuning the buckle-type quick release 20 to match the use length of the bicycle frame 1.
[0016] Through the above embodiments, the advantages of the present invention are as follows: Since the widths of bicycle frames 1 of different brands and models are different, the present invention can adjust the length of the adjustment rod 23 and the locking rod 32 at both ends, so that the buckle-type quick release 20 can adapt to more types of bicycle frames 1, thereby improving its applicability.
[0017] The buckle-type quick release 20 can be used to adjust the length at both ends. The length can be adjusted by rotating the adjustment rod 23 or the locking rod 32 without replacing the shaft rod or other parts, making it easy to adjust and more convenient and quick to use.
[0018] The adjusting rod 23 and the locking rod 32 are used to evenly shorten or lengthen the two ends of the shaft rod 21 to ensure that the shaft rod 21 does not deviate when assembled to the bicycle frame 1, thereby achieving a more stable bicycle and smoother rotation of the wheel axle.
[0019] The buckle-type quick release 20 with adjustable length at both ends has a longer service life, because when the bicycle needs to be replaced, only the length of the shaft rod 21 needs to be adjusted to continue using it, without replacing the entire buckle-type quick release 20, and the maintenance cost is lower.
[0020] The above-described embodiments are only preferred embodiments for fully illustrating the present invention, and the protection scope of the present invention is not limited thereto. Equivalent substitutions or changes made by those skilled in the art based on the present invention are within the protection scope of the present invention. The protection scope of the present invention shall be subject to the claims.
