[0002] In modern society, there are many multifunctional devices that work together to create a living environment suitable for people to live and work. In order to ensure the smooth operation of these functional devices, they are usually installed and fixed in a fixed manner. On the other hand, in order to reduce the impact of vibration and noise generated by these functional devices during operation on the surrounding living environment, corresponding shock absorbers can be equipped to reduce this negative impact. Especially in some places with high requirements for the living environment, the application of shock absorbers is very common. The existing shock absorbers are common shock absorbers, including metal spring shock absorbers and rubber shock absorbers, both of which have their own shortcomings. For rubber shock absorbers, metal parts are usually also contained. The vibration reduction effect is achieved by combining the structure of metal parts and rubber parts. According to the different vibration reduction objects and installation methods, the structure of the rubber shock absorber needs to be changed and designed in a targeted manner so that it can be applied to the corresponding scene environment. Under the premise of simplifying the structure and ensuring the vibration reduction effect of the rubber shock absorber, it is one of the difficulties of the rubber shock absorber to achieve rapid and effective installation of the rubber shock absorber, and the structural design of the existing rubber shock absorber needs to be improved and optimized.

[0022] Example:

[0023] The following is a detailed description of the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0024] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0025] See attached Figure 1-5 As shown, a rubber vibration damper comprises a mounting seat 1, a rubber vibration damper body 2 and a metal part; the rubber vibration damper body 2 is fixed on the mounting seat 1, and a plurality of mounting holes are provided on the mounting seat 1; the metal part is partially embedded in the rubber vibration damper body 2 along the central axis. Specifically, in an embodiment as shown in the accompanying drawings, the metal part is a bolt assembly 3, and the bolt assembly 3 extends toward the upper side of the rubber vibration damper body 2 along the central axis of the rubber vibration damper body 2, and is used to install the equipment unit. This embodiment is a floor-standing rubber vibration damper. When installing, first remove the fixing bolts of the bolt assembly 3 on the rubber vibration damper body 2, then align the mounting holes of the unit bracket with the bolt holes on the vibration damper, tighten the fixing bolts to fix the two together, and then fix the rubber vibration damper together with the unit bracket at the installation position through the mounting seat 1 to complete the vibration damping installation. The use of this rubber vibration damper can effectively prevent the rust of metal parts. The rubber vibration damper itself has a low inherent frequency, a moderate damping ratio, a high lateral stiffness, a low dynamic coefficient, a good vibration isolation effect, a small size and stable performance. It is especially suitable for vibration reduction installation of mechanical equipment such as fans, water pumps, engines and air compressors, and has a significant vibration reduction effect on equipment with impact vibration.

[0026] As a preferred embodiment, see the attached Figure 2 As shown, in this embodiment, the bottom surface of the mounting seat 1 and the upper side surface of the rubber vibration damper 2 are provided with anti-skid patterns 4. The anti-skid patterns 4 on the upper side effectively prevent the relative sliding between the unit bracket and the rubber vibration damper 2, thereby improving the fixing effect on the equipment unit; the anti-skid patterns 4 on the lower side effectively prevent the relative sliding between the rubber vibration damper and the mounting surface (usually the ground), thereby improving the overall installation and fixing effect of the rubber vibration damper and the equipment unit. It is feasible that the mounting seat 1 of this embodiment is also made of rubber material, and is integrally molded and manufactured with the rubber vibration damper 2, thereby simplifying the production and manufacturing process. Of course, the mounting seat 1 and the rubber vibration damper 2 can also be split structures, and the two can be assembled in a detachable connection and fixation manner.

[0027] In some other embodiments, see the attached Figure 3-4 As shown, the rubber vibration damper also includes a hanger 5, and the mounting seat 1, the rubber vibration damper 2 and the bolt assembly 3 are installed on the inner bottom of the hanger 5, and the top of the hanger 5 is provided with a hanging bolt 6. In this embodiment, the bolt assembly 3 extends along the central axis of the rubber vibration damper 2 to the upper and lower sides of the rubber vibration damper 2, wherein the lower side is used as the mounting end for hanging the equipment unit, that is, this embodiment is actually a hanging type rubber vibration damper. The rubber vibration damper is installed on the hanger rod of the ceiling wall through the hanging bolt 6, and the equipment unit that needs to be hung (such as a fan coil unit, an air duct, etc.) can be installed on the hanger 5 through the bolt assembly 3 on the lower side of the rubber vibration damper 2. After hanging, the vibration of the equipment unit during operation is effectively attenuated by the vibration damping buffer of the rubber vibration damper 2, thereby achieving the effect of vibration reduction and noise reduction. The open structure design of the hanger 5 and the rubber vibration damper 2 has a simple structure and is convenient for intuitive observation and operation adjustment during installation, so that the equipment unit can be hoisted in the best state, which is not only beneficial to improving the vibration reduction and silencing effect, reducing noise and vibration pollution to the surrounding environment, but also beneficial to extending the service life of the equipment unit and the vibration damper.

[0028] In this embodiment, the hanging bolt 6 includes a damping rubber block 7 for forming a series structure with the rubber vibration damper 2 to improve the damping coefficient. Specifically, the damping rubber block 7 is a rubber ring block with a large thickness, which is sleeved on the outside of the hanging bolt 6. Since the central axes of the hanging bolt 6, the rubber vibration damper 2, the bolt assembly 3 and the damping rubber block 7 are all on the same straight line in this embodiment, a series structure in spatial orientation is formed. When the equipment unit is correctly hoisted on the rubber vibration damper, when the equipment unit is running and vibrates, the rubber vibration damper 2 and the damping rubber block 7 are simultaneously subjected to forces in the same direction. Both will deform due to their own material characteristics, and attenuate the vibration generated by the equipment unit, achieving the effect of vibration reduction and noise reduction. The damping coefficient of the series structure formed by the rubber vibration damper 2 and the damping rubber block 7 in this embodiment is relatively large, which can achieve better vibration reduction and noise reduction effects.

[0029] It should be noted that the hanger 5 of the present utility model can be used as shown in the attached Figure 3 The closed annular frame structure shown in the figure can also be used as shown in the attached figure. Figure 4 The semi-enclosed annular frame structure with the disconnected gap 8 is easier to process and produce, and the hangers 5 of rubber shock absorbers of different models can be flexibly set according to the models and functional requirements of the rubber shock absorbers.

[0030] The installation and use operation process of the rubber vibration damper of this embodiment is as follows: first remove the top hanging bolt 6 to align its fixing bolt hole with the hanging rod mounting hole, and then connect and fix the two together through the hanging bolt 6, that is, first fix the rubber vibration damper to the ceiling through the hanging rod; remove the fixing nut of the bottom bolt assembly 3, align the screw rod with the mounting hole of the equipment unit and then tighten the fixing nut again, that is, hang the equipment unit on the rubber vibration damper through the bolt assembly 3, and complete the hanging of the equipment unit. After hanging, judge whether the equipment unit is installed in place by the compression amount of the rubber vibration damping body 2 and whether it is offset, so as to ensure the correct use of the rubber vibration damper and achieve the vibration reduction and noise reduction effect.

[0031] In some other embodiments, see the attached Figure 5 As shown, the metal part includes a cover body portion 9 extending from top to bottom, and the cover body portion 9 is sleeved on the outer side of the rubber vibration damper 2, that is, in this embodiment, the rubber vibration damper 2 is covered by the metal part, so that the rubber vibration damper of this embodiment has a good anti-shear function, and the overall product structure height can be made lower, thereby reducing the installation height and further improving the applicability of the rubber vibration damper.

[0032] The above only describes the preferred embodiments of the utility model, which should not be construed as limiting the claims. The utility model is not limited to the above embodiments, and its specific structure is allowed to be changed. In short, all changes made within the protection scope of the independent claims of the utility model are within the protection scope of the utility model.
