Description

Technical Field

[0001] This utility model relates to the field of mechanical installation buffer structures, and in particular to a vibration-damping foot pad device. Background Technology

[0002] In the existing equipment installation process, in order to reduce the impact of vibration generated by the operation of mechanical equipment on the ground and the equipment itself, anti-vibration pads are usually installed at the bottom of the equipment.

[0003] Common shock-absorbing pad structures often feature a flat bottom design, with the cushioning structure typically consisting of simple rubber blocks or elastic layers. However, these structures are prone to instability over long-term use, especially under heavy dynamic loads or continuous vibrations, where the cushioning effect gradually weakens, leading to reduced equipment operational stability.

[0004] Furthermore, the contact distance between the bottom of existing shock-absorbing pads and the ground is relatively small, which cannot effectively disperse the vertical pressure and vibration impact from the equipment, further affecting the cushioning performance. Especially when the ground is uneven or the center of gravity of the equipment is shifted, these pads are more prone to shifting or localized wear, reducing their service life. Utility Model Content

[0005] To address the shortcomings of existing technologies, the purpose of this invention is to provide a shock-absorbing foot pad device. This foot pad device offers better cushioning performance and higher stability.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A vibration-damping foot pad device includes: a connecting part, a transition section, a reinforcing section, and a base; the connecting part is cylindrical, with a receiving groove at its center for mounting equipment feet, and an axial through hole in the receiving groove for installing fasteners; the transition section is located below the connecting part, and its outer contour is an arc-shaped curved surface structure that tapers towards the center; the reinforcing section is located below the transition section, is cylindrical, and its outer diameter is basically the same as the outer diameter of the connecting part; the transition section and the reinforcing section have cylindrical buffer grooves; the base is located below the reinforcing section, and has a downwardly expanding bowl-shaped structure, forming a buffer cavity communicating with the buffer grooves; the connecting part, transition section, reinforcing section, and base are integrally formed.

[0008] Furthermore, the foot pad device is made of natural rubber with a rubber content of 55%.

[0009] Furthermore, the height of the buffer cavity is 18cm to 22cm.

[0010] Furthermore, the bottom diameter of the buffer cavity is 54cm to 66cm.

[0011] Furthermore, the inner surface of the base is a continuous arc-shaped curved surface, and its bottom center thickness is greater than its edge thickness.

[0012] Furthermore, the axial through hole connects to the cylindrical buffer groove.

[0013] The aforementioned vibration-damping foot pad device forms a stable multi-layered buffer structure through the integrated design of the connecting part, transition section, reinforcing section and bowl-shaped base. Combined with the cylindrical buffer grooves in the transition section and reinforcing section and the buffer cavity at the bottom, it effectively improves the device's shock resistance and buffering capacity. In particular, the outward-expanding bowl-shaped structure of the base increases the contact distance with the ground, enhances the stability of the overall structure, and solves the problems of poor buffering and unstable support of existing foot pads.

[0015] Figure 2 This is a cross-sectional view of the anti-vibration foot pad device provided according to this utility model. Detailed Implementation

[0016] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and 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.

[0017] like Figure 1 and Figure 2 As shown, this application provides a vibration-damping foot pad device, which includes: a connecting part 1, a transition section 2, a reinforcing section 3, and a base 5.

[0018] Specifically, the connecting part 1 is cylindrical, with a central receiving groove 11 for mounting the equipment feet. The receiving groove 11 contains an axial through hole 12 for installing fasteners. The transition section 2 is located below the connecting part 1, and its outer contour is an arc-shaped curved surface structure that tapers towards the center, effectively dispersing stress and improving the overall structural flexibility. The reinforcing section 3 is located below the transition section 2, and is cylindrical, with an outer diameter approximately the same as that of the connecting part 1. The reinforcing section 3 increases the structural thickness of the buffer area, improving the overall structural strength. Cylindrical buffer grooves 4 are provided within the transition section 2 and the reinforcing section 3, providing buffer space for the deformation of the transition section 2. The base 5 is located below the reinforcing section 3, and has a downwardly expanding bowl-shaped structure, forming a buffer cavity 6 that communicates with the buffer groove 4. The connecting part 1, transition section 2, reinforcing section 3, and base 5 are integrally formed.

[0019] Through the above-described design, the foot pad device forms a multi-level buffer system in transition section 2 and reinforcing section 3, exhibiting excellent buffering response under vertical loads and vibration impacts. This effectively suppresses equipment jumping and offset, significantly improving equipment operational stability. Simultaneously, the bowl-shaped base 5 increases the contact distance with the ground, maintaining high stability even on uneven ground or when the equipment's center of gravity shifts, preventing slippage or wear. The integrated, one-piece molding design enhances overall strength, preventing loosening or damage caused by structural splicing, thereby extending the device's service life.

[0020] The foot pads are made of natural rubber with a rubber content of 55%. Compared to ordinary rubber or composite materials, natural rubber with a 55% rubber content has a strong adhesion to smooth surfaces, making it less prone to slippage. At the same time, this material exhibits superior elasticity, cushioning performance, and service life. Furthermore, its uniform material structure allows it to maintain a stable deformation response under repeated loads, significantly improving the cushioning stability and fatigue life of the shock-absorbing foot pads, effectively reducing wear and tear on the pad structure during equipment operation.

[0021] The height of the buffer cavity 6 ranges from 18cm to 22cm to provide a wide range of energy absorption capacity, effectively improving the device's buffering response to strong vibrations or continuous impacts. Simultaneously, these structural parameters allow the foot pad device to adapt to different equipment loads, maintaining good buffering performance while avoiding structural stress concentration caused by insufficient compression stroke, thereby extending its service life.

[0022] The bottom diameter of the buffer chamber 6 ranges from 54cm to 66cm, which, compared to traditional small-sized foot pads, can better distribute the impact force and uneven load during the operation of heavy-duty equipment, significantly improving overall cushioning performance and service life. This range of designs achieves stability while maintaining a compact structure, adapting to different installation spaces.

[0023] like Figure 2 As shown, the inner surface of base 5 is a continuous arc-shaped curved surface, with its center thickness greater than its edge thickness. By setting a structural gradient with a thicker center and thinner edges, the pressure resistance and cushioning performance of the foot pads can be significantly improved without increasing the overall size. This thickness difference gives base 5 the ability to provide zoned cushioning, enabling the device to maintain good stability and energy absorption capacity under various load modes.

[0024] The axial through hole 12 connects to the cylindrical buffer groove 4, which not only realizes the mechanical connection function, but also guides the load transmission path to the buffer area in a reasonable way, thereby improving the buffering efficiency and structural coordination.

[0025] The above description of embodiments of the present invention, through which those skilled in the art are able to implement or use the present invention, will be readily apparent to those skilled in the art. Various modifications to these embodiments will be readily apparent to those skilled in the art. The general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not to be limited to the embodiments shown herein, but is to be accorded the widest scope consistent with the principles and novelty disclosed herein.
