Description

Technical Field

[0001] This utility model relates to the field of spring shock absorber technology, and in particular to spring shock absorbers. Background Technology

[0002] According to Chinese Patent No. CN218844955U, this utility model relates to a spring shock absorber, which includes a support plate and a chassis. Three sets of connecting components connect the support plate and the chassis. A shock-absorbing spring is connected in the middle between the support plate and the chassis. A limiting structure is provided inside the shock-absorbing spring. Each set of connecting components includes a first universal ball, which is fixed to the bottom of the support plate by a connecting post. A second universal ball sleeve is fixed to the top of the chassis. A second universal ball is movably connected inside the second universal ball sleeve. An outer sleeve is fixed to the top of the second universal ball. The entire spring shock absorber has a reasonable structure, ingenious design, and flexible use. By utilizing the connecting components in the shock-absorbing structure, the entire shock absorber can adapt to shock-absorbing paths with different tilt angles and meet different usage requirements. At the same time, the shock-absorbing structure is relatively stable. Combined with the two-stage buffer structure at the bottom, the shock-absorbing effect of the entire spring shock absorber is better, and it has strong practicality.

[0003] The aforementioned prior art and related documents have the following technical problems:

[0004] 1. Spring shock absorbers commonly found in the current market cannot adapt to equipment with different vibration characteristics. Utility Model Content

[0013] Beneficial effects

[0014] In this invention, a central spring and a top cover are installed inside the outer shell, and a damping oil tank is also located inside the outer shell. The central spring resonates and absorbs vibration energy, while the damping oil diffuses the vibration energy to reduce high-frequency vibration. The preload of the central spring is achieved through bolts and a pressure plate. By changing the preload, it can adapt to equipment with different vibration characteristics. The central spring's ability to resonate and absorb vibration energy, combined with the damping oil in the damping oil tank to diffuse the vibration energy, significantly reduces high-frequency vibration, making the equipment run more smoothly and reducing vibration damage. Furthermore, by adjusting the preload of the central spring through bolts and a pressure plate, it can be adjusted according to the vibration characteristics of different equipment, thereby providing a more precise and effective vibration reduction effect and enhancing the adaptability of the shock absorber to different working conditions.

[0021] To make the technical means, creative features, and achieved objectives and effects of this utility model easier to understand, the present utility model is further described below with reference to specific embodiments and accompanying drawings. However, the following embodiments are merely preferred embodiments of this utility model and not all of them. Other embodiments obtained by those skilled in the art based on the embodiments described in the implementation plan without creative effort are all within the protection scope of this utility model.

[0022] The specific embodiments of this utility model are described below with reference to the accompanying drawings. Specific Implementation Example 1:

[0024] Reference Figure 1-4 The spring shock absorber includes a housing 1, a threaded interface 8 on the top of the housing 1, a top cover 9 on the top of the housing 1 connected to the top of the housing 1, a front cover 2 with six positioning bolts 11 at the bottom and threadedly connected to the housing 1 via the positioning bolts 11, a sealing cover 3 at the bottom of the front cover 2 and snap-fitted to the front cover 2, a pressure adjusting bolt 7 inside the housing 1, a central spring 6 on one side of the pressure adjusting bolt 7 and fitted together with the pressure adjusting bolt 7, a spring pressure plate 5 on one side of the pressure adjusting bolt 7 and slidingly connected to the pressure adjusting bolt 7, a groove on the upper surface of the spring pressure plate 5, the bottom of the central spring 6 extending into the groove, a limiting block 10 on one side of the pressure adjusting bolt 7 and passing through the limiting block 10, the limiting block 10 and the pressure adjusting bolt 7 fitted together, and the pressure adjusting bolt 7 located at the center of the central spring 6, a front cover 2 at the bottom of the housing 1, and a damping oil tank 4 inside the housing 1.

[0025] A central spring 6 and a top cover 9 are installed inside the outer casing 1, and a damping oil tank 4 is also installed inside the outer casing 1. This allows the central spring 6 to resonate and absorb vibration energy, while the damping oil diffuses the vibration energy to reduce high-frequency vibration. The preload of the central spring 6 is achieved through bolts and a pressure plate. By changing the preload, it can adapt to equipment with different vibration characteristics. The central spring 6 can resonate and absorb vibration energy, and together with the damping oil in the damping oil tank 4, it can diffuse the vibration energy, significantly reducing high-frequency vibration, making the equipment run more smoothly, and reducing the damage of vibration to the equipment. At the same time, the preload of the central spring 6 can be adjusted by adjusting the positioning bolts 11 and the pressure plate, which can be adjusted according to the vibration characteristics of different equipment, thereby providing a more precise and effective shock absorption effect and enhancing the adaptability of the shock absorber to different working conditions.

[0026] The central spring 6 resonates. When external vibrations are transmitted to the spring damper, they contain vibrations of various frequencies. If a certain frequency component is equal to or very close to the natural frequency of the central spring, the central spring 6 will begin to absorb this vibration energy and resonate, thus efficiently absorbing the vibration energy. The damping oil in the damping oil tank 4 can effectively diffuse the vibration energy. The two work together to significantly reduce high-frequency vibrations, ensure the smooth operation of the equipment, and greatly reduce the damage caused by vibration to the equipment. Furthermore, the preload of the central spring 6 can be precisely adjusted with the help of the positioning bolt 11 and the spring pressure plate 5, thus perfectly adapting to the vibration characteristics of different equipment and providing extremely precise and effective damping for different working conditions. This greatly enhances the adaptability and reliability of the damper in various complex usage scenarios. Specific Implementation Example 2:

[0028] Reference Figure 1-4 The sealing cap 3 and the front cover 2 are connected by threads, which makes it easier to replace the damping oil in the damping oil tank 4 during use. This makes it more convenient and practical to add oil to the damping oil tank 4.

[0029] In summary:

[0030] The device employs a central spring 6 and a top cover 9 located inside the outer casing 1, with a damping oil tank 4 inside the casing 1. This allows the central spring 6 to resonate and absorb vibration energy, while the damping oil diffuses the vibration energy to reduce high-frequency vibrations. The preload of the central spring 6 is achieved through bolts and a pressure plate. By changing the preload, it can adapt to equipment with different vibration characteristics. The central spring 6 can resonate and absorb vibration energy, and in conjunction with the damping oil in the damping oil tank 4, it can diffuse the vibration energy, significantly reducing high-frequency vibrations, making the equipment run more smoothly, and reducing vibration damage to the equipment. At the same time, the preload of the central spring 6 can be adjusted by using the positioning bolts 11 and the pressure plate to adjust according to the vibration characteristics of different equipment, thereby providing a more precise and effective vibration reduction effect and enhancing the adaptability of the shock absorber to different working conditions.
