Description of the new model: [Technical field to which the new model belongs] The original creative department-a kind of shock absorber ', especially a designer for the rear shock absorber which is specially used to connect between the rear frame and the rear frame. T Gang [Previous Technology] In the field of bicycle design, based on improving the comfort of the bicycle and riding, some bicycle frames are designed as ^ car power moon dagger and the rear frame connected to the rear end of the front frame -A rear shock absorber is installed between the front section and the rear section to cushion shock. X-frame bicycle rear shock absorber (30) material 1, which is not shown in the figure 'its system includes a telescopically variable cavity 1 and a spring (3 2), wherein the suspension rod (3 (3 axis The tube and the shaft part connected to the end of the shaft tube and capable of relatively telescopic movement. The shaft officer and the shaft are each provided with a retaining ring, of which the design on the shaft tube is adjusted in position, and the spring (3 2) Department: 1 Steel wire can be spirally straightened with the same outer diameter :: / The elastically shrinkable suspension rod (Kawakami, for the shaft tube and: the rod can extend ^ φ, ϋ ,, _ one of 4¾% clip "Hold this", so that the rear shock absorber (30 〇) can be dreamed, following its front and rear section of the frame, and can provide self :: ==, Rishou, using a telescopic shock absorber The purpose of damping springs is to reduce the effect of daylight, and achieve the design of the front and rear shock absorbers. Although the structure design of the rear shock absorber can be achieved, there is no == salty earthquake purpose. The spring set on the suspension rod uses the elastic steel wire with a round cross-section because of the righteousness, and is designed as a straight cylindrical body with a spiral circumference of equal diameter M270987, as shown in the eighth figure Because the spring (3 2) of the rear shock absorber (3 0) has a predetermined length (L) of the number of pre-rolled and broken loads, the distance between the two adjacent coils is too small, so that the spring The compressible shock-absorbing stroke (d) is short, which makes it not enough to achieve a better ideal state. At the same time, the spring also has the disadvantage of poor elastic fatigue resistance. [New content] "The main point of this creation The purpose is to provide-bicycle rear shock absorbers. I hope to take this 6 measures to improve the shortcomings of the spring suspension and poor elastic fatigue resistance of the existing rear shock absorbers. The proposed technical solution is that the bicycle rear shock absorber includes a suspension rod which can be telescopically changed in length and a set of springs arranged on the cymbal suspension rod. The spring is a shape composed of elastic steel wires spirally wound for several turns. The spring system has a large outer diameter in the middle section and a tapered outer diameter toward both ends in the axial direction. The design of the shock absorber after the creation is based on the design of the front opening technology, compared with the existing after the front opening. The characteristics of this shock absorber include at least: After creation, the shock absorber uses its spring to have a larger outer diameter in the middle section and gradually reduce the outer diameter toward both ends in the axial direction, so that the smaller diameter ring in the elastic ring can be compressed and placed in the larger The inner position of the circle of the circle diameter further increases the compressible shock-absorbing stroke of the elastic yellow 'to improve the anti-fatigue performance of the spring and make it effective: increase the shock absorption performance of the shock absorber; except for this creation, The shock absorber can also use a spring-shaped body with a smaller outer diameter at the middle section and a smaller outer diameter at the two ends to also present a rough and personalized appearance. M270987 [Embodiment] The rear shock absorber of this creative bicycle (such as the first The specific implementation design of a shown in Figures 2 and 2 is to reduce the length of the suspension rod (:; the embodiment 'which mainly includes-elastic ... on the stretchable ... and-set on the suspension rod (the suspension The vibrating rod (10) includes a shaft tube (1 i), a surname * 7 α, 1 1), and can be relatively telescopically connected to the shaft.

In this embodiment, the cross section of the spring (20) t steel wire is circular. The spring (20) has a larger outer diameter of the main middle ring portion (2i) and has a tapered outer diameter toward the spiral shaft ring portion (22). The shape structure design, when it is assembled on the bicycle, the rear shock absorber (!) Can be connected with the suspension rod (work 0): the shaft (1 2) and the shaft tube (ii) at both ends respectively to move in the bicycle , Connect the front and rear frames (2) (3) (as shown in the fourth picture) '), So that when people ride a bicycle with the rear shock absorber, they can borrow the retractable suspension rod (1 0) and the rear shock absorber (1) when crossing the uneven road through 6 M270987. The compression and pressure relief effect of the compressible spring (20) achieves the purpose of damping (as shown in the third figure), so that the bicycle has good riding comfort.

When being compressed, the smaller ring diameter (2 2 is in the middle of the larger ring diameter (2 1).) (3) The shock-absorbing stroke of the spring (3 2) is increased by increasing the shock-absorbing stroke (D) which can be compressed between the adjacent two turns (20) of the spring (20). In addition, it can reduce the weight and so on, which can cushion the shock absorption performance; In addition, the spring-shaped body with a smaller outer diameter and a smaller outer diameter at both ends after creation creates a rough and personalized visual effect.
