Description

Technical Field

[0001] This utility model belongs to the field of vibration reduction and protection technology, specifically relating to a vibration reduction and protection device for small-load instruments and equipment. Background Technology

[0002] During the use and transportation of precision instruments, experimental equipment, or electronic devices, mechanical vibrations and impacts from the external environment or the device itself are unavoidable. If these vibrations and impact energies are directly transmitted to the equipment, they can cause minor issues such as distorted measurement data and unstable operation, or even serious problems such as damage to internal precision components, structural fatigue, or equipment failure. Some existing vibration damping devices may have problems such as simple structure and insufficient damping dimensions. For example, relying solely on springs or rubber pads for cushioning often makes it difficult to effectively cope with combined vibrations from horizontal, vertical, or even multiple directions simultaneously, and they lack the ability to adaptively adjust to impact loads, resulting in limited protection for small, precise, and valuable instruments and equipment with low loads.

[0003] Chinese Patent Publication No. CN222502523U discloses a vibration damping and protection device for small-load instruments and equipment. The device includes an upper rubber ring and a lower rubber ring positioned below the upper rubber ring. An inner hole is formed at the inner middle position of both the upper and lower rubber rings. A metal tube is connected to the inner hole of the upper rubber ring, and a pressure ring is positioned at the outer lower end of the metal tube. A rubber airbag is positioned inside the inner hole of the lower rubber ring, and an inflation valve is connected to the middle right side of the rubber airbag. An inflation pipe is provided at the connection between the inflation valve and the lower rubber ring. The rubber airbag, as a key vibration damping element in the device, provides an additional buffer layer with its internal gas, absorbing more energy upon impact and effectively reducing vibration transmitted to the instruments and equipment. By adjusting the pressure inside the airbag through the inflation valve, the vibration damping effect can be flexibly adjusted according to different working conditions and load requirements, achieving personalized vibration damping settings.

[0004] However, the aforementioned device has the following problems: during vibration reduction, it relies solely on a single airbag layer structure for buffering, and its internal damping characteristics and support stiffness are relatively fixed, making it difficult to effectively cope with complex and variable vibration spectra. This single structure not only has poor absorption effect on high-frequency fine vibrations, but also is prone to sudden stiffness changes when subjected to large impact loads, resulting in a significant decrease in vibration reduction efficiency and failing to provide comprehensive and reliable vibration protection for precision instruments. Therefore, we propose a vibration reduction and protection device for small-load instruments and equipment. Summary of the Invention

[0005] The purpose of this invention is to provide a vibration damping and protection device for small-load instruments and equipment, which can solve the problems of simple structure and limited vibration damping effect in related technologies.

[0006] The specific technical solution adopted by this utility model is as follows: A vibration damping and protection device for small-load instruments and equipment includes a base plate. A first vibration damping groove is formed at the bottom of the base plate. A first rubber ring is fixedly installed inside the first vibration damping groove. Sliding T-slots are formed at both ends of the top surface of the base plate. Closing blocks are fixedly installed at the ends of the two sets of sliding T-slots. A vibration damping component is provided at one end of the two sets of closing blocks. An airbag assembly is provided along the periphery of the top of the base plate. A connecting ring is provided at the top of the airbag assembly.

[0007] The vibration damping assembly includes a spring disposed at one end of the closing block, a vibration damping T-shaped block disposed at one end of the spring, the vibration damping T-shaped block being slidably connected to the inside of the sliding T-shaped groove, a first vibration damping block disposed at the top of the vibration damping T-shaped block, and a vibration damping rod being rotatably connected inside the first vibration damping block.

[0008] The top of the damping rod is provided with a second damping block, and the top of the two sets of second damping blocks are provided with an extension block. The bottom of the extension block is provided with a compression spring.

[0009] The surface of the compression spring is provided with a telescopic tube, and the bottom of both the telescopic tube and the compression spring are located in the middle of the top surface of the base plate. The top of the extension block is located in the middle of the bottom surface of the connecting ring.

[0010] The airbag assembly includes an airbag layer disposed around the top periphery of the base plate, the top of the airbag layer being disposed around the bottom periphery of the connecting ring, an air inlet being disposed on the surface of the airbag layer, and an air-sealing cap being threadedly connected to the surface of the air inlet.

[0011] The connecting ring has a second vibration damping groove inside, a second rubber ring is provided inside the second vibration damping groove, and a sealing cap is provided on the top of the second vibration damping groove.

[0012] Both sides of the base plate and the connecting ring are provided with threaded plates, and the internal threads of the threaded plates are connected to external screws.

[0013] The technical effects achieved by this utility model are as follows: 1. By setting up the airbag assembly, this utility model can form an adjustable flexible buffer support between the equipment and the base plate using the airbag layer, effectively absorbing and dispersing vibration and impact energy from different directions, thereby significantly improving the vibration reduction and protection effect; at the same time, the cooperation between the air inlet and the air-sealing cover allows the air pressure inside the airbag to be flexibly adjusted according to the actual load, enhancing the device's adaptability to different working conditions, protecting the instruments and equipment from vibration damage, and improving the stability and practicality of the overall structure.

[0014] 2. By setting up vibration damping components, this utility model can utilize the synergistic effect of springs and compression springs to provide elastic buffering in both horizontal and vertical directions, effectively absorbing and dissipating impact and vibration energy from multiple directions. The cooperation between the damping rod and the damping block further transforms rigid impact into controllable rotation and deformation, thereby significantly reducing the amplitude and acceleration transmitted to the instruments and equipment. This achieves multi-level and multi-directional vibration damping protection, ensuring the stable operation and safety of the equipment under complex working conditions. Attached Figure Description

[0017] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0018] like Figure 1-5As shown, a vibration damping and protection device for small-load instruments and equipment includes a base plate 1. A first vibration damping groove is formed at the bottom of the base plate 1, and a first rubber ring 2 is fixedly installed inside the first vibration damping groove. Sliding T-slots 3 are formed at both ends of the top surface of the base plate 1. Closing blocks 4 are fixedly installed at the ends of both sets of sliding T-slots 3. A vibration damping component 5 is provided at one end of each set of closing blocks 4. An airbag assembly 6 is provided along the periphery of the top of the base plate 1, and a connecting ring 7 is provided at the top of the airbag assembly 6. The vibration damping component 5 includes a spring 501 located at one end of the closing block 4. A vibration damping T-block 502 is provided at one end of the spring 501. The vibration damping T-block 502 is slidably connected to the inside of the sliding T-slot 3. A first vibration damping block 503 is provided at the top of the vibration damping T-block 502, and a vibration damping rod 504 is rotatably connected inside the first vibration damping block 503. A second damping block 505 is provided at the top of the damping rod 504. An extension block 506 is provided at the top of both sets of second damping blocks 505. A compression spring 507 is provided at the bottom of the extension block 506. A telescopic tube 508 is provided on the surface of the compression spring 507. The bottoms of the telescopic tube 508 and the compression spring 507 are both located in the middle of the top surface of the base plate 1. The top of the extension block 506 is located in the middle of the bottom surface of the connecting ring 7. Through the setting of the damping component 5, the synergistic effect of the spring 501 and the compression spring 507 can provide elastic buffering in both horizontal and vertical directions, effectively absorbing and dissipating impact and vibration energy from multiple directions. The cooperation between the damping rod 504 and the two sets of damping blocks further transforms rigid impact into controllable rotation and deformation, thereby significantly reducing the amplitude and acceleration transmitted to the instrument and equipment. This achieves multi-level and multi-directional vibration protection, ensuring the stable operation and safety of the equipment under complex working conditions. The airbag assembly 6 includes an airbag layer 601 disposed around the top periphery of the base plate 1. The top of the airbag layer 601 is located around the bottom periphery of the connecting ring 7. An air inlet 602 is provided on the surface of the airbag layer 601, and a sealing cover 603 is threadedly connected to the surface of the air inlet 602. The surface of the sealing cover 603 is provided with multiple sets of threaded strips, which facilitates the increase of friction between the operator's hand and the sealing cover 603 for easier turning. Through the setting of the airbag assembly 6, the airbag layer 601 can form an adjustable flexible buffer support between the equipment and the base plate 1, effectively absorbing and dispersing vibration and impact energy from different directions, thereby significantly improving the vibration reduction and protection effect. At the same time, the cooperation between the air inlet 602 and the sealing cover 603 allows the air pressure inside the airbag to be flexibly adjusted according to the actual load, enhancing the adaptability of the device to different working conditions, protecting the instrument and equipment from vibration damage, and improving the stability and practicality of the overall structure. The connecting ring 7 has a second vibration damping groove 8 inside, and a second rubber ring 9 is installed inside the second vibration damping groove 8. A sealing cap 10 is installed on the top of the second vibration damping groove 8. Threaded plates 11 are provided on both sides of the base plate 1 and the connecting ring 7. External screws are threaded into the internal parts of the threaded plates 11. The external screws and threaded plates 11 facilitate the connection of the device to external equipment.

[0019] The working principle of the device is as follows: First, the first damping groove at the bottom of the device and its internal rubber ring will contact the mounting base, forming the first barrier to absorb and weaken the initial high-frequency micro-amplitude vibration from the bottom. Next, the core damping component 5 begins to play a leading role: In the horizontal direction, the damping T-block 502 in the sliding T-slot 3 can adaptively slide slightly under the push of the spring 501 to buffer lateral impact; in the vertical direction, the upper compression spring 507, in conjunction with the telescopic tube 508, is compressed or extended, effectively absorbing and dissipating most of the vertical impact energy. Simultaneously, the rotating connection design between the damping rod 504 and the damping block cleverly converts some of the rigid impact into rotational kinetic energy, further smoothing the vibration. The airbag assembly 6 surrounding the device works synchronously. The air pressure inside it forms a wrap-around flexible damping field, which not only helps to bear part of the load, but also effectively suppresses displacement and sway in all directions. It also generates a coupling effect with the core vibration reduction mechanism, and together they gradually transform the violent and destructive mechanical impact and vibration into controllable and gentle kinetic and deformation energy within the system, ultimately ensuring that the protected precision instruments and equipment operate stably in a stable and isolated environment.

[0020] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
