Description

Technical Field

[0001] This utility model relates to the field of vibration reduction technology, and more specifically, to a combined vibration damper. Background Technology

[0002] Vibration dampers are devices used to reduce the noise and vibration amplitude of equipment during operation.

[0003] Chinese invention patent CN108533656A discloses a rubber vibration damper, and its background section describes "the current traditional vibration damper structure and installation method as follows..." Figure 1 and Figure 2 As shown, each product 6 is equipped with four vibration dampers. Each vibration damper includes a rubber damping pad 7, a pressure cap 8, and screws 9. The rubber damping pad 7 has an "I"-shaped structure. The rubber damping pad 7 is first installed on the product, and then it is installed on the mounting base plate using the pressure cap 8 and screws 9. Four through holes are made at the four corners of the mounting base plate for fixing to external machinery. The entire vibration damper described above is not only large in size (mainly due to the presence of the base plate), making installation on the product very cumbersome, but also its vibration damping load cannot be freely combined and adjusted, thus limiting its application range.

[0005] To solve the above-mentioned technical problems, this utility model proposes a combined vibration damper, comprising:

[0008] The device also includes a vibration damping module for connecting the upper mounting frame and the lower mounting frame; characterized in that there are two or more vibration damping modules, which are arranged along the length of the upper mounting frame and the lower mounting frame.

[0009] In the above technical solution, both the upper mounting frame and the lower mounting frame are rectangular frame structures. The upper end of the side plate of the upper mounting frame along its length direction has a first connecting part formed by bending outwards, and the lower end of the side plate of the lower mounting frame along its length direction has a second connecting part formed by bending outwards.

[0010] The vibration damping module is connected at one end to two first connecting parts and at the other end to two second connecting parts.

[0043] The following embodiments will provide a detailed description of a combined vibration damper of this application.

[0044] Example 1:

[0045] like Figures 1-5As shown, in this embodiment, a combined vibration damper includes: an upper mounting frame 1; a lower mounting frame 2; and a vibration damping module 3 for connecting the upper mounting frame 1 and the lower mounting frame 2; wherein, there are two or more vibration damping modules 3, which are arranged along the length direction of the upper mounting frame 1 and the lower mounting frame 2.

[0046] The vibration damping module 3 is a structure used for vibration damping. Since different equipment requires different vibration damping loads, in order to improve the applicability of the vibration damper, the vibration damping module 3 is designed to be able to be added or removed. By adding the vibration damping module 3, the load of the entire vibration damper can be increased, and correspondingly, by removing the vibration damping module 3, the load of the entire vibration damper can be reduced.

[0047] Specifically, both the upper mounting bracket 1 and the lower mounting bracket 2 are configured as rectangular frame structures. The upper end of the side plate of the upper mounting bracket 1 along its length direction has a first connecting part 11 formed by bending outward, and the lower end of the side plate of the lower mounting bracket 2 along its length direction has a second connecting part 21 formed by bending outward.

[0048] The vibration damping module 3 is connected at one end to two first connecting parts 11 and at the other end to two second connecting parts 21.

[0049] By setting the upper mounting bracket 1 and the lower mounting bracket 2 as a rectangular frame structure, the vibration damping module 3 can be installed along the length direction, which is very convenient and practical.

[0050] Example 2:

[0051] This embodiment is a further improvement based on Embodiment 1.

[0052] like Figures 1-5 As shown, in this embodiment, the vibration damping module 3 includes: an upper connecting plate 31 located on the upper port of the upper mounting frame 1, and both ends of the upper connecting plate 31 are respectively connected to two first connecting parts 11; a lower connecting plate 32 located on the lower port of the lower mounting frame 2, and both ends of the lower connecting plate 32 are respectively connected to two second connecting parts 21; and a vibration damping part disposed between the upper connecting plate 31 and the lower connecting plate 32.

[0053] The vibration damping unit includes: an upper mounting plate 33 disposed at the bottom of the upper connecting plate 31; a lower mounting plate 34 disposed at the top of the lower connecting plate 32; a vibration damping block 35 disposed between the upper mounting plate 33 and the lower mounting plate 34; and a connector for connecting the upper mounting plate 33 and the lower mounting plate 34.

[0054] By adopting the above structure, the vibration damping module 3 is not only simple in structure and easy to install, but also has high strength and good load resistance.

[0055] In this embodiment, the connector includes: an upper pressure plate 36 connected to an upper mounting plate 33, with both sides of the upper pressure plate 36 bent downwards to form an upper baffle; a lower pressure plate 37 connected to a lower mounting plate 34, with both sides of the lower pressure plate 37 bent upwards to form a lower baffle; and a bolt and nut assembly 38, which has two sets and connects the upper baffle and the lower baffle on the same side respectively.

[0056] The side of the damping block 35 rests against the upper baffle and the lower baffle.

[0057] By setting an upper pressure plate 36 and a lower pressure plate 37, and then using two upper side baffles and two lower side baffles to limit the vibration damping part, the installation strength of the vibration damping part is effectively improved, and the vibration damping part is not easy to fall off even under high frequency vibration.

[0058] It should be noted that both upper and lower baffles have ear plates positioned away from the vibration damping section. Each ear plate has bolt holes, and the two sets of bolt and nut assemblies 38 connect the upper pressure plate 36 and the lower pressure plate 37 through the bolt holes on the four ear plates. The ear plates on the upper and lower baffles facilitate the installation of the bolt and nut assemblies 38. Most importantly, the bolt and nut assemblies 38 do not need to act on the vibration damping section, thus avoiding direct contact while effectively locking the upper pressure plate 36 and the lower pressure plate 37.

[0059] It should be noted that the upper pressure plate 36 is welded to the upper connecting plate 31; the lower pressure plate 37 is welded to the lower connecting plate to improve the overall strength.

[0060] It should be noted that the damping block 35 is made of elastic material. Specifically, it can be a rubber pad or a spring, as long as it can provide cushioning and rebound. In this embodiment, a square rubber pad is used as the damping block 35.

[0061] In this embodiment, the lower half of the upper mounting bracket 1 is optimized to surround the upper half of the lower mounting bracket 2. This allows each side plate to wrap around the vibration damping module 3, providing protection and dust prevention, and preventing scratches from external objects.

[0062] Example 3:

[0063] This embodiment is a further improvement based on Embodiment 2.

[0064] like Figures 1-5 As shown, in this embodiment, the first connecting part 11 has a plurality of first mounting holes 12 that are equally spaced along its length direction; the second connecting part 21 has a plurality of second mounting holes 22 that are equally spaced along its length direction.

[0065] The upper connecting plate 31 is adjustablely mounted on the upper mounting bracket 1 through the first mounting hole 12; the lower connecting plate 32 is adjustablely mounted on the lower mounting bracket 2 through the second mounting hole 22.

[0066] By providing the first mounting hole 12 and the second mounting hole 22, the vibration damping module 3 can be freely adjusted in position according to the site conditions. Specifically, the vibration damping module 3 is first assembled (the specific number to be assembled is as needed, such as 2, 3, 4, etc.), with the upper connecting plate 31 of the vibration damping module 3 not installed temporarily. Then, the lower mounting bracket 2 is placed on each vibration damping module 3, followed by the upper mounting bracket 1 being placed on the lower mounting bracket 2. Subsequently, the position of the assembled vibration damping module 3 is adjusted, and then the second connecting part 21 on the lower mounting bracket 2 is connected to the lower connecting plate 32 with bolts. Finally, the upper connecting plate 31 is installed on the upper mounting plate 33, and the upper connecting plate 31 is connected to the first connecting part 11 on the upper mounting bracket 1 with bolts.

[0067] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, nor are they limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments. The terminology used herein is chosen to best explain the principles, practical application, or improvement of the technology in the market, or to enable others skilled in the art to understand the embodiments disclosed herein.
