Technical Field

[0001] This utility model belongs to the technical field of machine foot rubber ring structure, and particularly relates to a machine foot rubber ring. Background Technology

[0002] Mechanical equipment inevitably experiences vibrations of varying degrees during operation, which can easily cause damage. Rubber rings on machine feet are typically used to reduce the impact of mechanical vibrations on the normal operation of machines, structures, or instruments.

[0003] The existing rubber rings on machine feet have poor cushioning and load-bearing capacity. Under long-term operation of mechanical equipment, the rubber rings on the machine feet will be damaged, which will seriously affect their performance. Utility Model Content

[0004] The purpose of this utility model is to provide a rubber ring for machine feet to solve the technical problems mentioned in the background art.

[0005] To achieve the above objectives, the specific technical solution of this utility model is as follows: A machine foot rubber ring includes an upper rubber ring and a lower rubber ring located below the upper rubber ring. The inner cavities of the upper and lower rubber rings are filled with nylon cores, and gaskets are fitted on the top and bottom of the upper rubber ring and the lower rubber ring, respectively. A shell is fitted on the outer side of the upper and lower rubber rings, and the outer wall of the gasket contacts the inner wall of the shell. The upper and lower rubber rings are connected by a damping pad. An installation head is provided at the top of the upper rubber ring, and a threaded groove is provided in the middle of the upper surface of the installation head. Multiple rectangular openings are provided on the side walls of the upper and lower rubber rings in a circumferential array, and a buffer ring is provided in each rectangular opening.

[0006] Preferably, the bottom of the outer casing is provided with an anti-slip and wear-resistant pad.

[0007] Preferably, the outer diameter of the gasket is larger than the outer diameters of the upper and lower rubber rings, and the outer diameter of the gasket is equal to the inner diameter of the outer shell.

[0008] Preferably, the inner wall of the outer shell is provided with four limiting strips arranged in a circumferential array, and the side wall of the gasket is provided with four limiting openings that correspond one-to-one with the limiting strips, and the limiting openings are slidably connected to the limiting strips.

[0009] Preferably, the outer diameter of the damping pad is smaller than the outer diameters of the upper and lower rubber rings.

[0010] Preferably, the outer diameter of the mounting head is equal to or less than the outer diameter of the upper rubber ring, and the upper surface of the outer shell is flush with the upper surface of the upper rubber ring.

[0011] The rubber ring for machine feet of this utility model has the following advantages:

[0012] 1. This utility model, through the design of the outer shell, positions the upper and lower rubber rings in the center inside the shell, ensuring a uniform load distribution within the shell and effectively reducing wear. Furthermore, the outer shell encloses the upper and lower rubber rings, preventing direct contact with the external environment and extending their service life. The damping pads further enhance the shock absorption of the machine foot rubber rings, while also increasing their load-bearing capacity, significantly improving their service life and practicality.

[0013] 2. The rectangular opening and buffer ring of this utility model enable the rubber ring to have a strong load-bearing capacity and shock absorption effect, and provide contraction space for the upper and lower rubber rings, which can effectively prevent the rubber ring from breaking due to the limited contraction space.

[0014] 3. By installing gaskets on both the upper and lower rubber rings, the upper and lower rubber rings are axially reinforced, ensuring uniform load distribution across the entire machine foot rubber ring. This also enhances the load-bearing capacity of the machine foot rubber ring and prevents direct contact between the upper and lower rubber rings and the outer casing, thus avoiding damage to the upper and lower rubber rings.

[0026] To better understand the purpose, structure, and function of this utility model, the following description, in conjunction with the accompanying drawings, provides a more detailed account of a machine foot rubber ring according to this utility model.

[0027] like Figure 1-4As shown, this utility model discloses a machine foot rubber ring, including an upper rubber ring 7 and a lower rubber ring 8 located below the upper rubber ring 7. The inner cavities of the upper rubber ring 7 and the lower rubber ring 8 are filled with a nylon inner core 13. The nylon inner core 13 enhances the rigidity of the upper rubber ring 7 and the lower rubber ring 8. A gasket 6 is fitted on the top of the upper rubber ring 7 and the bottom of the lower rubber ring 8. A shell 1 is fitted on the outer side of the upper rubber ring 7 and the lower rubber ring 8. The outer wall of the gasket 6 contacts the inner wall of the shell 1. The shell 1 positions the upper rubber ring 7 and the lower rubber ring 8 in the center inside the shell 1, so that the load on the upper rubber ring 7 and the lower rubber ring 8 is evenly distributed inside the shell 1, which can effectively reduce wear. The shell 1 also wraps around the upper rubber ring 7 and the lower rubber ring 8, preventing them from directly contacting the outside world and extending their service life. The bottom of the outer casing 1 is provided with an anti-slip and wear-resistant pad 2. The anti-slip and wear-resistant pad 2 can increase the wear resistance and friction between the bottom of the outer casing 1 and the ground, and has a good anti-slip effect. The outer diameter of the pad 6 is larger than the outer diameter of the upper rubber ring 7 and the lower rubber ring 8, and the outer diameter of the pad 6 is equal to the inner diameter of the outer casing 1. By fitting the pad 6 on both the upper rubber ring 7 and the lower rubber ring 8, the upper rubber ring 7 and the lower rubber ring 8 are axially reinforced, ensuring that the load distribution of the entire machine foot rubber ring is uniform, while enhancing the load-bearing capacity of the machine foot rubber ring, and avoiding direct contact between the upper rubber ring 7 and the lower rubber ring 8 and the outer casing 1, which would cause damage to the upper rubber ring 7 and the lower rubber ring 8. The inner wall of the outer shell 1 is provided with four limiting strips 5 arranged in a circular array, and the side wall of the gasket 6 is provided with four limiting ports 9 that correspond one-to-one with the limiting strips 5. The limiting ports 9 are slidably connected to the limiting strips 5. Through the cooperation between the limiting strips 5 and the limiting ports 9, the gasket 6 and the outer shell 1 are well limited, which can effectively prevent the gasket 6 from rotating inside the outer shell 1.

[0028] The upper rubber ring 7 and the lower rubber ring 8 are connected by a damping pad 12. The outer diameter of the damping pad 12 is smaller than the outer diameters of the upper rubber ring 7 and the lower rubber ring 8. The damping pad 12 improves the shock absorption effect of the rubber ring of the machine foot, while also increasing its load-bearing strength, greatly improving its service life and practicality. The top of the upper rubber ring 7 is provided with a mounting head 3. The upper surface of the mounting head 3 has a threaded groove 4 in the middle. The outer diameter of the mounting head 3 is equal to or smaller than the outer diameter of the upper rubber ring 7, and the upper surface of the outer shell 1 is flush with the upper surface of the upper rubber ring 7. The mounting head 3 is connected and fixed to the machine foot through the threaded groove 4. The sidewalls of the upper rubber ring 7 and the lower rubber ring 8 are provided with multiple rectangular openings 10 arranged in a circumferential array, and each rectangular opening 10 is provided with a buffer ring 11. Through the arrangement of the rectangular openings 10 and the buffer rings 11, the rubber rings have strong load-bearing capacity and shock absorption effect, and provide contraction space for the upper rubber ring 7 and the lower rubber ring 8, which can effectively prevent the rubber rings from breaking due to the limited contraction space.
