Adjust the nut again, that is, each time you install or remove the front wheel, you need two procedures. If the frequency of replacement between installation and disassembly is frequent, it will bring inconvenience to the user. Therefore, the quick release structure still needs to be improved. Need. [20] SUMMARY OF THE INVENTION The main object of the present invention is to provide a quick release structure that increases the displacement distance required for assembly and disassembly, and allows the bicycle rim to be quickly installed or disassembled on the front fork of the bicycle, thereby increasing the use. Convenience. 4 200838761 A secondary object of the present invention is to provide a quick release structure that adjusts the required axial length according to the length of the axles of different rims, thereby making it easier for the user to replace rims of different sizes. In order to achieve the above object, the quick release structure of the present invention comprises an abutting member having a constant hole; a mandrel is inserted through the through hole of the abutting member, and the opposite side of the member is axially moved; An eccentric structure is pivotally disposed on one of the mandrels, and a displacement component is coupled to the other end of the mandrel relative to the handle, and is displaced by a predetermined distance relative to the mandrel; thereby, when the handle is released, the handle is released Thereafter, the displacement assembly displacement creates a gap that allows the 10 bicycle hub of the present invention to be quickly removed from the front of the bicycle to increase ease of use.

Therefore, the diameter of the two end edges of the linking member 43 is larger than the diameter of the positioning groove 435, and the diameter of the positioning groove 435 is larger than the sliding groove. The two positioning members 47 are disposed in the two positioning holes 417 of the distance adjusting member 41, and are coupled to the linking member 43. The sleeve member 49 has a hollow cylindrical shape, and a continuous tooth portion 491 is disposed on the outer side thereof. The _ portion is provided with a ring-shaped retaining portion 498. One of the first positioning concave portion 497 and the second positioning concave portion are spaced apart from each other by a predetermined distance. The second concave portion 497 and the second concave portion 498 are spaced apart from each other. After the sleeve 49 is inserted into the mandrel 2, the adjustment member 47 is a card 1 4y7 or a second depression 498.绖 From the above structure, the operation of the present invention is as follows: 7 200838761 I first 'As shown in the third figure, the two positioning members 47 are located in the linkage positioning groove 435 and the first positioning recess of the sleeve member 49. 497, the shaft member 43 can be rotated by a pressing member. The pressing portion 431 of the linking member 43 is pressed as shown by::, the linking member 43 is moved to make the two positioning members 47. Sliding to the sliding groove 433, at this time, the first positioning concave portion 497 of the sleeve member 49 is slid, and the two linking members 43 can continue to slide inward; finally, as shown in the fifth figure, the: The member 47 is moved to the second positioning recess of the sleeve member 49, and the 43 is received by Na (10) 45, and the second positioning recess is located between the second positioning recess and the positioning groove 435; On the second axis 2. When the position of the linkage member 43 and the elastic member ## is not moved, the positioning of the sleeve member 49 is lightly shifted by a predetermined distance for the called 2G. 15 20 60 of the ginseng", the present invention is installed on the front wheel of the bicycle. The clothes are firstly engaged with the tambourine 6 自行车, between the & 64 'then the mandrel 2 ( Passing through the hub (9), and then mounting the assembly 40 (4) to the 2G thread segment 23 sleeve == portion 491 is connected to the front portion 62; at this time, the pivoting portion adjusts the abutting member 1〇 The distance between the displacement members 4〇 is in accordance with the width of the hub 60; then the handle is moved downwardly, and the eccentric structure is such that the abutting member 1G and the displacement assembly 40 abut the other 62&64, And the belt is fixed 6 〇. Also, when the front wheel is disassembled, as shown in the seventh figure, first: Chuan 'make the urging member 10 and the displacement assembly 4 〇: = linkage member ❿ to move the two positioning members 47 To the sleeve member 8 200838761 62 ^ let the sleeve member 49 move outwards 'the displacement assembly 40 and the gap 4 is generated by 4' so that the hub 60 can be removed from the front wheel. It should be noted that, referring to the sixth figure, when the sleeve abuts the clamp member 47, since the shifting member 41 is slid to the mandrel, the distance adjusting member 41 is also opposite to the f. Forcing the second training member 47, ==吏 inadvertently pressing the linking member 43, nor causing the two positioning members 47 to move, thereby generating a protective effect. Technical Du IcT % (4) seventh figure, when the sleeve is broken After the release of 49, the set of the axe of the set of axe is subjected to the resistance of the latching portion 43 of the distance adjusting member 41, so that the set of the retaining member 49 does not fall off due to loosening. When the front wheel of the same rim is to be more fortunate, the ship member of the position and the member can be sculpted with respect to the screwing position of the mandrel 2 () and the member 1G and the displacement member 4 () The length of the shaft is such that the quick-release structure of 15 20 可 can conform to the axial length of different rims. By the foregoing description, the present invention can be summarized as follows: 1. The quick-release structure of the present invention, by which the displacement assembly 4 The component of the cymbal, the displacement distance of the _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ _ The length of the axle of the different rims, ^ adjusting the position of the spacing member 41 of the displacement assembly 40 relative to the spindle 20 causes the quick release structure to produce different axial lengths for the user The first embodiment is a perspective view of a preferred embodiment of the present invention. The second figure is an exploded perspective view of a preferred embodiment of the present invention. The three figures show a state in which the first positioning position of the 5-displacement assembly is shown in a sectional view of a preferred embodiment of the present invention.
