[0035] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0036] This application provides a high-impact vibration isolator, which will be described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0037] To address the technical problems of complex internal structure and inconvenient damping force adjustment in existing high-impact vibration isolators, an embodiment of this application provides a high-impact vibration isolator. This is described in detail below.

[0038] like Figure 1 and Figure 2 As shown, a high-impact vibration isolator includes...

[0039] The base has an upper seat 13 and an upper cover 14 at its upper end. The upper seat 13 is located inside the upper cover 14. The upper cover 14 is threaded to the outer wall of the base. A damping mechanism is installed between the upper cover 14 and the upper seat 13.

[0040] The lower end of the support member passes through the upper cover 14, the damping mechanism and the upper seat 13 and extends into the seat cavity of the base. An elastic buffer mechanism is provided between the lower end of the support member and the base, and a buffer pad 45 is provided between the support member and the upper seat 13.

[0041] The damping mechanism includes an upper retaining ring 31, a damping ring 32, and a conical ring 33. The damping ring 32 is located inside the conical ring 33 and sleeved on the outside of the bearing member. The upper retaining ring 31 is located between the damping ring 32 and the upper cover 14. The upper cover 14 adjusts the damping force between itself and the outer wall of the bearing member by squeezing the opening and closing ring through the upper retaining ring 31.

[0042] The damping ring 32, also known as the opening and closing ring, is composed of multiple ring plates that surround the bearing component. When the upper cover 14 presses down on the upper retaining ring 31, the opening and closing ring radially contracts and squeezes the outer wall of the bearing component, increasing friction and thus increasing the damping force when the bearing component moves up and down.

[0043] Specifically, as an optional implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, a first step is formed on the damping ring 32, and a pressure ring 34 is placed in the first step. A second step is formed on the pressure ring 34, and a disc spring 35 is provided between the second step and the upper retaining ring 31.

[0044] The disc spring 35 is designed to compensate for wear caused by vibration and impact. The disc spring 35 also presses against the opening and closing ring to prevent it from loosening. The fit of each step enhances the stability of the entire structure.

[0045] Specifically, as an optional implementation method in this embodiment, such as Figure 1 and Figure 2 As shown, an O-ring 36 is provided on the outside of the cone ring 33, and the damping mechanism contacts the inner wall of the upper cover 14 through the O-ring 36 to reduce lateral impact.

[0046] When the load-bearing component is subjected to lateral impact, an O-ring 36 is added to prevent the cone ring 33 from hitting the upper cover 14. The O-ring 36 is a rubber part, thereby reducing the impact.

[0047] Specifically, as an optional implementation method in this embodiment, such as Figure 1 As shown, the carrier includes

[0048] The cap 21 has a damping ring 32 sleeved on the outside of the cap 21, and the buffer pad 45 is disposed on the outer step at the lower end of the cap 21.

[0049] The lower end of the adjusting bolt 22 is inserted into the cap 21, and the upper end extends out of the cap 21 and is connected to the hexagonal ring 24. The shoulder on the adjusting bolt 22 abuts against the inner step at the upper end of the cap 21, and the cap 21 and the adjusting bolt 22 are locked together by the hexagonal ring 24.

[0050] Adjusting nut 23 is mounted on adjusting bolt 22.

[0051] In this embodiment, the outer wall of the cap 21 and the damping ring 32 are in frictional engagement, and the cap 21, adjusting bolt 22, hexagonal ring 24 and adjusting nut 23 are connected as a whole and move up and down together.

[0052] Specifically, as an optional implementation method in this embodiment, such as Figure 1 As shown, the elastic buffer mechanism includes

[0053] A mesh pad 41 is disposed on the base and located below the adjusting bolt 22, wherein the adjusting bolt 22 makes contact with the mesh pad 41 for buffering.

[0054] The mesh sleeve 42 is disposed on the base and located below the cap 21, wherein the cap 21 and the mesh sleeve 42 provide contact buffering.

[0055] The upper end of the coil spring 43 abuts against the adjusting nut 23, and the lower end abuts against the base;

[0056] The upper end of the cone spring 44 abuts against the lower end of the cap 21, and the lower end abuts against the base.

[0057] When the electrical equipment impacts downward through the load-bearing component, the damping mechanism provides damping force, and then the mesh pad 41, mesh sleeve 42, helical spring 43 and conical spring 44 provide upward elastic force, thereby providing cushioning for the load-bearing component.

[0058] The mesh pad 41 and the mesh sleeve 42 are metal wire mesh pads 41, which are existing technologies and will not be described in detail here.

[0059] Specifically, as an optional implementation method in this embodiment, such as Figure 1 As shown, a cylindrical pin 25 is provided on the adjusting nut 23, and a guide groove is formed inside the cap 21; the guide groove is formed axially in the cap 21.

[0060] One end of the cylindrical pin 25 is inserted into the adjusting nut 23, and the other end of the cylindrical pin 25 is inserted into the guide groove;

[0061] The adjusting nut 23 is restricted to rotate within the cap 21 by the cylindrical pin 25.

[0062] The working height of the helical spring 43 is determined by the position of the adjusting nut 23 on the adjusting bolt 22. After adjusting the position of the adjusting nut 23 according to the actual situation, the cylindrical pin 25 is connected between the adjusting nut 23 and the cap 21 to restrict the adjusting nut 23 to move only up and down.

[0063] Specifically, as an optional implementation method in this embodiment, such as Figure 2 As shown, the base includes a base plate 11 and a seat sleeve 12, with the base plate 11 located inside the seat sleeve 12 and threadedly connected.

[0064] The base plate 11 and the seat sleeve 12 are detachable structures, which facilitates the assembly of the entire vibration isolator and the processing of the base.

[0065] Assembly process of this utility model high-impact vibration isolator:

[0066] First, assemble the carrier component. Then, place the mesh pad 41, mesh sleeve 42, helical spring 43, and conical spring 44 inside the base. Then, insert the carrier component into the base. Next, put the buffer pad 45 on the lower end of the cap 21. Finally, tighten the upper seat 13 on the base.

[0067] Next, install the cone spring 44, damping ring 32, pressure ring 34, disc spring 35, and upper retaining ring 31 on the upper seat 13. Finally, screw on the upper cover 14 and adjust the damping force between the damping ring 32 and the cap 21 through the upper cover 14.

[0068] The high-impact vibration isolator of this invention has redesigned its internal damping and buffering structures. The internal damping structure is simple, eliminating the need for straight and curved springs used in traditional vibration isolators.
