Description

Technical Field

[0001] This utility model relates to the field of generator vibration reduction technology, specifically to vibration damping pads. Background Technology

[0002] During operation, generators experience not only vertical impacts but also horizontal slippage. This necessitates additional securing devices to restrain them, increasing installation complexity and impacting vibration damping. Utility Model Content

[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a shock-absorbing pad to solve the problem of generator slippage in the existing technology.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: A shock-absorbing pad includes: an elastic portion that undergoes elastic deformation under external force, the elastic portion having a first end; the shock-absorbing pad further includes: The first protrusion protrudes from the edge of the first end and together with it forms the first adsorption cavity; At least one second protrusion is disposed in the first adsorption cavity and together with the first end forms a second adsorption cavity; The first adsorption cavity and the second adsorption cavity are arranged to allow gravity to drive them and to interact with objects through suction.

[0005] Furthermore, the first adsorption cavity and the second adsorption cavity face the same side.

[0006] Furthermore, the surface of the first protrusion is flush with or below the surface of the second protrusion.

[0007] Furthermore, the first protrusion surrounds and encloses the first end.

[0008] Furthermore, the first protrusion gradually widens and extends away from the elastic portion.

[0009] Furthermore, the second adsorption cavity is configured as a flared opening.

[0010] Furthermore, the elastic part has a second end, the first end and the second end are arranged opposite to each other, and the second end is provided with at least one fixing post.

[0011] Furthermore, the fixed column is coaxially provided with a stop portion, and the circumferential width of the stop portion gradually narrows from the second end away from it, so as to form a stop opening with the second end.

[0012] Furthermore, the first end is provided with a fixing hole, which is independently provided with the second adsorption cavity, and the fixing hole passes through the first end and the second end.

[0013] Furthermore, the first end is provided with at least one anti-slip part, and the anti-slip part and the second adsorption cavity are provided independently of each other.

[0014] Compared to existing technologies, this invention offers the following advantages: When a generator starts, stops, or experiences load changes, horizontal forces can easily cause slippage. The first and second adsorption cavities, when pressed down by the weight of the equipment, expel the air within, creating negative pressure and effectively preventing generator slippage. Furthermore, placing the first and second adsorption cavities at the elastic portion not only absorbs vibration and impact but also eliminates the need for additional restraint devices, facilitating rapid installation and improving anti-slip and impact resistance stability.

[0017] The present invention will be further described in detail below through specific embodiments: In the embodiments of this utility model, such as Figure 1 As shown, the shock-absorbing pad 100 includes: an elastic portion 2, a first protrusion 3, and at least one second protrusion 4; the elastic portion 2 is capable of elastic deformation under external force and has a first end 201; the first protrusion 3 protrudes from the edge of the first end 201 and forms a first adsorption cavity 301 together with it; the second protrusion 4 is disposed in the first adsorption cavity 301 and forms a second adsorption cavity 401 together with the first end 201; wherein, the first adsorption cavity 301 and the second adsorption cavity 401 are arranged to allow gravity to drive and to interact with objects through suction.

[0018] Specifically, in this embodiment of the invention, the shock-absorbing pad 100 has an elastic part 2, which can convert the vibration of the generator into its own deformation, thereby achieving a shock-absorbing effect. The elastic part 2 can be made of rubber, such as nitrile rubber (NBR), which has oil resistance and fuel resistance suitable for generators, while also having good wear resistance and high mechanical strength, thus achieving an effective shock absorption effect.

[0019] In this embodiment of the utility model, in order to prevent the generator from shifting and to facilitate installation, a first protrusion 3 and a second protrusion 4 are provided at the first end 201 of the elastic part 2.

[0020] Specifically, the first protrusion 3 protrudes from the edge of the first end 201 of the elastic part 2 to form a first adsorption cavity 301, and a second adsorption cavity 401 formed by the second protrusion 4 and the first end 201 is provided within the first adsorption cavity 301. Thus, the first adsorption cavity 301 and the second adsorption cavity 401 enable the damping pad 100 to form a double-cavity structure. When the generator is placed above the damping pad 100, the two adsorption cavities can be compressed by the generator's own weight, creating a negative pressure that forms a negative pressure fixing mode to prevent the generator from slipping. Furthermore, using two independent and nested adsorption cavities provides dual suction protection. Even if one cavity is not properly sealed due to external factors (such as uneven mounting surface or foreign objects), the other adsorption cavity can still provide effective adsorption force, thereby improving the generator's stability. Of course, as... Figure 1 , Figure 2As shown, in this embodiment, multiple second protrusions 4 are provided, and these multiple second protrusions 4 are arranged at equal intervals along the edge path of the first adsorption cavity 301. This allows the multiple second protrusions 4 to form multiple independently arranged second adsorption cavities 401 with the first end 201, thereby employing a multi-cavity structure to further improve the stability of the generator and prevent displacement. Furthermore, the first adsorption cavity 301 and the second adsorption cavity 401 are constructed at the first end 201 of the elastic part 2 and rely on the generator's own gravity to generate negative pressure. No additional fixing device is required for constraint, making the structure simple and easy to install.

[0021] This embodiment utilizes the vibration generated by the generator during operation and its own gravity to compress the adsorption cavity, creating negative pressure and generating an interaction force, thereby reducing the vibration amplitude and displacement of the generator during operation and increasing the service life of the generator.

[0022] like Figures 1-3 As shown, in one embodiment, the first adsorption cavity 301 and the second adsorption cavity 401 face the same side. Specifically, in order to form a double adsorption cavity structure so that both can work together at the mounting surface, this embodiment makes the first adsorption cavity 301 and the second adsorption cavity 401 face the same side. Under the action of the generator's own gravity, the two adsorption cavities can be squeezed simultaneously, and the two adsorption cavities will generate negative pressure and adsorb onto the mounting surface, thereby improving the stability of the generator.

[0023] like Figure 3 As shown, in one embodiment, the surface of the first protrusion 3 is flush with or below the surface of the second protrusion 4. Specifically, when the two surfaces are flush, the first adsorption cavity 301 and the second adsorption cavity 401 can simultaneously contact the mounting surface and form a negative pressure, providing double the adsorption force. Conversely, when the two surfaces are staggered, i.e., the surface of the first protrusion 3 is below the surface of the second protrusion 4, a double-layer sequential adsorption structure can be formed. This structure is not only suitable for uneven mounting surfaces, but also ensures that at least one adsorption cavity can preferentially and reliably adsorb onto the mounting surface, or that more areas can be in contact with the mounting surface through different degrees of compression adsorption of the two adsorption cavities, thereby maximizing the effective contact area and adsorption force.

[0024] like Figure 1 , Figure 2 As shown, the first protrusion 3 surrounds and encloses the first end 201 to form a stable negative pressure under gravity, so that the first protrusion 3 and the first end 201 can be jointly constructed to form a first suction cup structure. Preferably, as shown... Figure 3 As shown, the first protrusion 3 gradually widens and extends away from the elastic portion 2. Figure 3As shown, the second adsorption cavity 401 is configured as a flared opening to form a second suction cup structure.

[0025] like Figure 1 , Figure 3 , Figure 4 As shown, in one embodiment, the elastic part 2 has a second end 202, the first end 201 and the second end 202 are arranged opposite to each other, and the second end 202 is provided with at least one fixing post 5. Specifically, in order to install the elastic part 2 to the base plate 8, this embodiment provides a fixing post 5 at the second end 202 of the elastic part 2, so that the shock-absorbing pad 100 is installed to the base plate 8 by means of plug-in connection. Figure 4 As shown, in order to improve the installation stability of the shock-absorbing pad 100, four fixing posts 5 are provided at the second end 202 of the elastic part 2 in this embodiment; in other embodiments, the number of fixing posts 5 may also be other, and is not limited here.

[0026] Furthermore, such as Figure 3 , Figure 4 As shown, in one embodiment, the fixing column 5 is coaxially provided with a stop portion 501. From the second end 202 away from it, the circumferential width of the stop portion 501 gradually narrows to form a stop opening 502 with the second end 202. Specifically, to prevent the shock-absorbing pad 100 from falling off, this embodiment provides a stop portion 501 coaxially with the fixing column 5. This stop portion 501 has an overall conical structure, and its large-diameter end is spaced apart from the second end 202, with both forming a stop opening 502. Figure 5 , Figure 6 As shown, the shock-absorbing pad 100 is installed on the base plate 8, and then the fixing post 5 is inserted into the corresponding hole of the base plate 8. Finally, the base plate 8 is locked into the stop 502, and the rotation or displacement of the shock-absorbing pad 100 can be restricted by the action of multiple stop 502s.

[0027] Furthermore, such as Figures 1-4 As shown, in one embodiment, the first end 201 is provided with a fixing hole 6. The fixing hole 6 and the second adsorption cavity 401 are independently provided, and the fixing hole 6 penetrates through the first end 201 and the second end 202. Specifically, this is to install the shock-absorbing pad 100 to the outer shell and to prevent the shock-absorbing pad 100 from rotating. In this embodiment, a fixing hole 6 is provided, which is located at the center of the elastic part 2 and can penetrate through its first end 201 and second end 202. A metal bushing is provided inside the fixing hole 6, which can be fixed to the outer shell by bolts.

[0028] like Figure 1 , Figure 2As shown, in one embodiment, the first end 201 is provided with at least one anti-slip part 7, and the anti-slip part 7 and the second adsorption cavity 401 are independently provided. Specifically, in order to increase the contact friction between the first end 201 and the mounting surface, this embodiment provides an anti-slip part 7 at the first end 201, which can play an anti-slip role.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
