[0042] The following will detail a shock absorber structure of the present application through the following embodiments.

[0043] Embodiment 1:

[0044] As Figure 1 and Figure 2 shown, in this embodiment, a shock absorber structure includes: an upper top plate 100, on which a first mounting hole is opened; a lower bottom plate 200, on which a second mounting hole is opened; a connecting member 300 for connecting the upper top plate 100 and the lower bottom plate 200; and a shock absorption part disposed between the upper top plate 100 and the lower bottom plate 200;

[0045] Among them, the connecting member 300 is also used to adjust the distance between the upper top plate 100 and the lower bottom plate 200, and further adjust the compression amount of the shock absorption part.

[0046] As described in the background art, the currently common shock absorbers have problems such as low installation strength and inconvenient installation by opening holes in the rubber shock pads and then using bolts to install the rubber shock pads on two objects. Therefore, in this application, first installation holes and second installation holes are respectively opened on the upper top plate 100 and the lower bottom plate 200. The first installation holes are distributed around the upper top plate 100, and the second installation holes are distributed around the lower bottom plate 200. Then, the upper top plate 100 and the lower bottom plate 200 are installed on two objects through bolts, which not only effectively improves the connection strength between the two objects, but also enables the shock absorption part to be replaced according to needs, or can be quickly replaced after the shock absorption part is damaged, which is very convenient.

[0047] The two objects connected to the upper top plate 100 and the lower bottom plate 200 mentioned above are the equipment and the base respectively. When the equipment is running, the vibration force generated by it will act on the upper top plate 100, and then the upper top plate 100 acts on the shock absorption part. The shock absorption part offsets the external force generated by the vibration of the equipment through its own damping performance, thereby achieving the shock absorption effect.

[0048] Specifically, the connecting member 300 includes: an upper pressing plate 310 connected to the upper top plate 100; a lower pressing plate 320 connected to the lower bottom plate 200; and a bolt-nut assembly 330 for connecting the upper pressing plate 310 and the lower pressing plate 320;

[0049] Wherein, the shock absorption part is arranged between the upper pressing plate 310 and the lower pressing plate 320;

[0050] Both sides of the upper pressing plate 310 are bent downward to form upper side baffles 311, and both sides of the lower pressing plate 320 are bent upward to form lower side baffles 321;

[0051] Wherein, the side surface of the shock absorption part abuts against the upper side baffles 311 and the lower side baffles 321.

[0052] By setting the upper pressing plate 310 and the lower pressing plate 320, and then using the two upper side baffles 311 and the two lower side baffles 321 to limit the shock absorption part, the installation strength of the shock absorption part is effectively improved, and even under high-frequency vibration, the shock absorption part is not easily detached.

[0053] In this embodiment, it should be noted that there are ear plates 312 arranged away from the shock absorption part on both the two upper side baffles 311 and the two lower side baffles 321, and bolt holes are opened on each ear plate 312;

[0054] Wherein, the bolt-nut assembly 330 has two groups and connects the upper pressing plate 310 and the lower pressing plate 320 respectively through the bolt holes on the four ear plates 312.

[0055] By providing lugs 312 on the upper baffle 311 and the lower baffle 321, it is convenient to install the bolt and nut assembly 330. The most important thing is that the bolt and nut assembly 330 does not need to act on the damping part. While avoiding direct contact with the damping part, it can tightly lock the upper pressing plate 310 and the lower bottom plate 200

[0056] It should be noted that the upper pressing plate 310 is welded to the upper top plate 100; the lower pressing plate 320 is welded to the lower bottom plate 200. To improve the overall strength.

[0057] It should be noted that the damping part is a rubber pad 400 or a spring, as long as it can play a buffering role and can rebound. In this embodiment, a square rubber pad 400 is used as the damping part.

[0058] In this embodiment, preferably, holes 410 are provided in the rubber pad 400, and damping springs (not visible in the figure) are provided in the holes 410. Under the dual damping of rubber damping and spring damping, the damping effect of the shock absorber structure can be greatly improved.

[0059] In this embodiment, preferably, for the shock absorber structure to be used in different application scenarios, an adhesive layer can be provided at the connection between the rubber pad 400 and the upper pressing plate 310 and the lower pressing plate 320. By providing the adhesive layer, the connection strength of the rubber pad 400 on the upper pressing plate 310 and the lower pressing plate 320 can be further improved.

[0060] In this embodiment, preferably, the bolt and nut assembly 330 includes: a bolt 331; a nut 332, which is matched with the bolt 331; and a rubber washer 333, which is sleeved on the bolt 331;

[0061] Wherein, one end of the rubber washer 333 abuts against the head of the bolt 331, and the other end abuts against the lug 312.

[0062] By additionally providing a rubber washer 333, it is possible to prevent the bolt 331 from directly contacting the lug 312, resulting in the conduction of vibration, so as to further improve the damping effect of the entire shock absorber structure.

[0063] Embodiment Two:

[0064] This embodiment is a further improvement based on Embodiment One.

[0065] As Figure 1 and Figure 2 shown, in this embodiment, notches 110 are provided on the upper top plate 100 and / or the lower bottom plate 200 facing the bolt and nut assembly 330.

[0066] By providing the notch 110, on the one hand, it helps to reduce the weight of the entire shock absorber structure; on the other hand, when the compression amount of the shock absorption part is relatively large, through the notch 110, the end of the bolt-nut assembly 330 can pass through the upper top plate 100 and / or the lower bottom plate 200, avoiding movement interference.

[0067] Embodiment Three:

[0068] This embodiment is a further improvement based on any of the above embodiments.

[0069] As shown in the figure, in this embodiment, fastening nuts 120 are provided on both the first mounting hole and the second mounting hole.

[0070] To facilitate the installation between the upper pressing plate 310, the lower pressing plate 320 and the equipment and the base, fastening nuts 120 are directly welded on the first mounting hole on the upper pressing plate 310 and the second mounting hole on the lower pressing plate 320. The welded fastening nuts 120 will not slip or become loose, so as to improve the installation efficiency of the bolts.

[0071] The various embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations are obvious to those of ordinary skill in the art in the technical field without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, the practical applications, or the improvements to the technologies in the market, or to enable other ordinary skill in the art in the technical field to understand the embodiments disclosed herein.
