Pressing type=2: Most of the sides are equipped with spring elements to generate the restoring force of the oil pressure. When riding the environment, the elevation angle of the gentle slope of the shock absorber is adjusted moderately: in case of riding on the uphill section, ? Increase - backward ===== [New content] e ^ force 疋 only use the housing spring to achieve the buffer stroke before the shock, it will affect the _ after the balance, the spring expansion ratio ^, 疋Therefore, if you can provide the buffer stroke of the 矜 / / + T adjustment (4) shock absorber without changing, it can help the R rider to change the county function. Main 2 = ί for - an adjustable stroke of the bicycle before the shock and structure, and outside the tube between them, 'sexual device * to generate buffer shock absorbers - upper adjustment rod ... shock absorber module, the suspension model The set is composed of a fine elastic spring, a spring fixed block, an adjusting block 盥5 M335457, and an adjustment rod; wherein the upper adjusting rod is coupled to the top of the compression spring by a spring fixing block, and the bottom of the compression spring is coupled with a Adjusting the block fastening joint, the adjusting block has a central screw hole for the lower adjusting rod to screw through the sleeve, and the bottom end is fixedly locked with the bottom of the outer fork tube; thereby, the shock absorber module is above and below After the end is connected with the knob at the upper edge of the inner fork sleeve and the bottom end of the outer fork tube, the rotation knob can be connected to the compression spring, and the bottom is fastened and the adjustment block is locked at the bottom end of the outer fork tube. Under the adjustment rod, the upper and lower displacements are made, so that the buffer stroke between the inner and outer fork tubes can be adjusted without changing the expansion ratio of the compression magazine. In order to make the above features and advantages of the present invention more obvious and understandable, a preferred embodiment will be described below, and the composition of the present invention and the functions achieved by the present invention will be described in detail as follows: Embodiments First, please refer to the first figure. This is a bicycle suspension front fork structure with adjustable stroke. It is mainly used in the suspension fork 1 〇 one of which is elastic-fitted to produce the shock absorber inside and outside. An adjustable stroke shock absorber 20 is disposed between the forks 1 1 and 1 2 . Please refer to the second diagram. The suspension module 20 includes: an upper adjustment rod 2 1 coupled to a compression spring At the top of 2 2, there is a convex ring gear 2 1 0 between the rod bodies, and the rod portion on the convex ring gear 2 1 0 can be extended to a top sleeve seat 30 fixed to the inner fork tube 11 and the knob 4 0 is locked, and the rod portion under the convex ring block 2 1 0 is a screw body 2 1 1 ; a compression spring 2 2, the top portion of which is formed into a tapered shape and is placed in a close-up manner. The constricted end 2 2 0 The bottom part is a short section of the tight end 22 1 ; a spring fixing block 2 3 is fastened to the top of the compression spring 2 2 6 M335457 end 2 2 〇 connected with the upper adjustment rod 2 1 Fixed, having a conical body with a central hole 203, which can be placed on the screw body 2 1 1 of the upper adjustment rod 2 1 and can be fastened and fixed to the compression spring 2 2 by a nut 24 The end of the 2 2 〇; an adjustment block 25, is placed in the tight end 2 2 1 of the bottom of the compression spring 2 2 'there has a central screw hole 2 5 〇, the bottom end and a protrusion, a bad 2 5 1 abuts against the bottom of the compression spring 2 2 , and the side of the retaining ring 2 5 1 is set to be a groove 2 2 2 for arranging a 0 ring 2 6 ; the adjustment lever 27 is an upper half The pole formed with the threaded section is screwed and sleeved with the adjusting block 25, and the bottom end is locked and fixed to the bottom of the outer fork tube i2, and the top end of the threaded rod of the threaded section is provided with a small section of the control. The sleeve end 271 is provided for a spacer 28, and the sleeve is provided with a radial through hole 27.2; the spacer 28' is located at the adjustment block of the compression spring 22. The inner side of the 25 is fixedly coupled with the sleeve end 2 71 of the lower adjustment rod 27, and has a pair of sockets 2 71 through the hole 2 7 2 of the jack 2 8 〇, which can be used for inspection. Its positioning is inserted. For the purpose of constructing the components of the preferred embodiment of the present invention, an overview of the relationship between the locations and the positions of the components is discussed; and then, (4) is read as the desired effect statement to be achieved as follows. Referring to the second and fourth figures, since the creation pressure portion forms the constricted end 2 2 0, it is available for $敕~ early top w. Upper listening #2 1 is fixed with the conical body, and the bottom of the conical spring 2 2 is tightly closed. 2 21 can be fastened with the adjustment block 25, and the adjustment block 2 5 is 7 M335457 core screw hole 2 5 〇The lower adjustment rod 2 7 is screwed together, so after the adjustment rod 27 and the outer fork tube 12 are locked and fixed, the compression spring 22 can be adjusted by the knob 40 connected with the upper adjustment rod 2 1 The compression spring 22 can be displaced up and down on the lower adjustment lever 27 by the adjustment block 25 which is fastened at its bottom portion. Advantageously, the top end of the lower adjustment lever 27 can be coupled to a pad. • 2 9 ′ can prevent the adjustment lever 27 from coming off the adjustment block 25 . " Furthermore, the adjusting block 25 of the bottom of the compression magazine 2 2 and the bottom end of the inner fork tube 1 1 can be sealed by a positioning block 5 掣, and the positioning block 50 is provided with a ring The groove 5 1 is provided for a buffer ring 6 〇. The shock absorbing module 2 组成 composed of the above components, because the upper and lower adjusting rods 2 1 and the lower adjusting rod 27 can be connected with the inner fork tube 1 1 , the knob 3 at the upper edge of the upper fork 3 and the outer fork The bottom end of the tube 1 2 is fixedly connected, so that when the knob 4 is turned, the compression spring 2 2 of the suspension module 2 can be locked to the outer fork tube 1 by the adjusting block 25 fastened by the bottom 4 The lower end of the adjusting rod 2 7 is vertically displaced, so that the suspension module 2 can adjust the inner and outer fork tubes 丄 and 丄 2 doors without changing the compression ratio of the compression spring 2 2 Those who buffer the strokes LI and L2 (as shown in the third and fourth figures).曰之•, In summary, this creation has its excellent progress in the same kind of products, while at the same time traversing domestic and foreign technical information about such structures, Wen ^ did not find the same structure exists In the first place, the creation of a new type of patent element has been submitted in accordance with the law.
