Description

Technical Field

[0001] The utility model relates to the technical field of shock absorber manufacturing, and more specifically, to a shock absorber. Background Art

[0002] Most traditional shock absorbers are equipped with compression springs to achieve shock absorption, but due to the limited outer diameter of the compression spring, the shock absorber using a single compression spring cannot achieve a large force-bearing area. If the force-bearing area is to be increased, it is necessary to arrange a certain number of compression springs, but it is easy to cause positional displacement when subjected to force, and the limit position is not infinite, resulting in poor overall effect. Based on this, the utility model proposes a shock absorber. Utility Model Content

[0006] The utility model is further configured as follows: the interval angles between two adjacent first C-shaped spring pieces are equal; and the interval angles between two adjacent second C-shaped spring pieces are equal.

[0007] The utility model is further configured as follows: a retaining ring passing through all the first C-shaped spring pieces and all the second C-shaped spring pieces is provided between the shock-absorbing bottom plate and the shock-absorbing top plate, and a first bracket connected to the shock-absorbing bottom plate and / or the shock-absorbing top plate is provided on the retaining ring.

[0009] The utility model is further configured as follows: an outer stopper is disposed on the back side of each of the first C-shaped spring pieces; and an inner stopper is disposed on the back side of each of the second C-shaped spring pieces.

[0010] In summary, the utility model has the following beneficial effects: the shock absorber involved in the utility model can greatly increase the overall diameter of the shock absorber through the C-shaped spring pieces distributed around it, so as to form a shock absorber with a larger diameter than height, which can be placed for use, has a large force-bearing area, a small overall height, is safe and reliable to use, has complete overall functions, and is highly practical.

Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in the field without creative work are within the scope of protection of the utility model.

[0014] The utility model is further described below in conjunction with the accompanying drawings and preferred embodiments.

[0015] Example 1

[0016] See also Figure 1 and Figure 2 As shown, a shock absorber involved in this embodiment includes a shock absorbing base plate 1 and a shock absorbing top plate 2 arranged above the shock absorbing base plate, and a plurality of first C-shaped spring pieces 3 with openings facing inward and second C-shaped spring pieces 4 with openings facing outward are arranged between the shock absorbing top plate 2 and the shock absorbing base plate 1, and one end of the second C-shaped spring piece 4 and the first C-shaped spring piece 3 are both connected to the shock absorbing base plate 1, and the other end are both connected to the shock absorbing top plate 2.

[0017] Further, any one of the first C-shaped spring pieces 3 is disposed between two adjacent second C-shaped spring pieces 4 ; and any one of the second C-shaped spring pieces 4 is disposed between two adjacent first C-shaped spring pieces 3 .

[0018] Furthermore, the interval angles between two adjacent first C-shaped spring pieces 3 are equal; the interval angles between two adjacent second C-shaped spring pieces 4 are equal.

[0019] In this embodiment, when the end surface of the shock-absorbing top plate 2 is compressed, the first C-shaped spring pieces 3 and the second C-shaped spring pieces 4 arranged around it are compressed to deform, thereby releasing force and achieving a shock-absorbing effect.

[0020] Example 2

[0021] See also Figure 1 and Figure 2 As shown, the shock absorber involved in this embodiment is further configured on the basis of Embodiment 1, wherein a retaining ring 5 passing through all the first C-type spring pieces and all the second C-type spring pieces is provided between the shock absorbing bottom plate 1 and the shock absorbing top plate 2, and the retaining ring 5 is provided with a first bracket 6 connected to the shock absorbing bottom plate and / or the shock absorbing top plate.

[0024] In this embodiment, before the first C-type spring piece 3 is compressed to the limit position, it will collide with the outer baffle 8, thereby achieving the deformation limiting effect on the first C-type spring piece 3, preventing it from losing its reset function due to excessive pressure; before the second C-type spring piece 4 is compressed to the limit position, it will collide with the inner baffle 9, thereby achieving the deformation limiting effect on the second C-type spring piece 4, preventing it from losing its reset function due to excessive pressure.

[0025] The shock absorber involved in the utility model can greatly increase the overall diameter of the shock absorber through the C-shaped spring pieces arranged around it, so as to form a shock absorber with a larger diameter than height, which can be placed for use, has a large force-bearing area, a small overall height, is safe and reliable to use, has complete overall functions, and is highly practical.
