Description

Technical Field

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

[0002] Mechanical vibration can affect the stability and reliability of electronic equipment operation. For example, mechanical vibration can cause the characteristic impedance of PCB microstrip lines to drift, the Q value of inductors to drop sharply after the carrier is vibrated, and the piezoelectric effect caused by mechanical vibration can cause large phase jitter in quartz crystal oscillators.

[0003] Currently widely used vibration isolation solutions, such as silicone granules or foam pads, have limited effectiveness. As high-frequency electronic equipment moves towards the MHz spectrum, the coupling effect of mechanical vibration and electromagnetic signals exhibits exponential amplification. Traditional vibration isolation solutions cannot meet the vibration isolation requirements of high-frequency electronic equipment, significantly impacting its normal operation. Therefore, there is an urgent need to design a vibration isolator with better vibration isolation performance. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings and deficiencies in the prior art and provide a vibration isolator. The vibration isolator adopts a double vibration isolation layer structure, and the two vibration isolation layers are arranged coaxially to buffer vibration energy in a coordinated manner, thereby improving the vibration energy dissipation efficiency and the vibration isolation effect.

[0005] To achieve the above objectives, this utility model is implemented through the following technical solution: a vibration isolator, including a base, a cap, a first vibration isolator layer and a second vibration isolator layer, and positioning components one and two respectively located on both sides of the vibration isolator object; the base is provided with a mounting shaft; the first vibration isolator layer, the first positioning component, the second positioning component, the second vibration isolator layer and the cap are sequentially inserted through the mounting shaft; the cap is also fixed to the mounting shaft.

[0006] The installation method of this vibration isolator is as follows: The vibration isolator has mounting holes. First, the first vibration isolation layer and the first positioning component of the vibration isolator are inserted onto the mounting shaft. Then, the mounting shaft is inserted into the mounting hole of the vibration isolator. Afterward, the second positioning component, the second vibration isolation layer, and the cap are inserted into the mounting shaft, and the cap is fixed to the mounting shaft. This vibration isolator is simple and convenient to install and has good versatility. The vibration isolator adopts a double vibration isolation layer structure, and the two vibration isolation layers are coaxially arranged, located on both sides of the vibration isolator. They work together to buffer vibration energy, improving vibration energy dissipation efficiency and enhancing the vibration isolation effect.

[0007] This vibration isolator can be applied to vibration isolation applications of high-frequency electronic equipment to prevent the stability and reliability of high-frequency electronic equipment from being affected by mechanical vibration; in addition, the vibration isolator can also be applied to other vibration isolation applications.

[0008] Preferably, the seat body is provided with a seat flange on the side near the vibration isolation layer one; the positioning member one is provided with a positioning flange one on the side near the vibration isolation layer one; the seat flange and the positioning flange one together position the vibration isolation layer one; The cap has a cover flange on the side near the second vibration isolation layer; the positioning member has a positioning flange on the side near the second vibration isolation layer; the cover flange and the positioning flange together position the second vibration isolation layer. This arrangement facilitates the positioning of the first vibration isolation layer between the base and the first positioning member, as well as the positioning of the second vibration isolation layer between the cap and the second positioning member.

[0009] Preferably, the sum of the height of the seat flange and the height of the positioning flange is less than the thickness of the vibration isolation layer, so that a gap is left between the seat flange and the positioning flange. The sum of the height of the cover flange and the height of the second positioning flange is less than the thickness of the second vibration isolation layer, so that a gap 2 is left between the cover flange and the second positioning flange. This arrangement can prevent the seat flange from contacting the first positioning flange and the cover flange from contacting the second positioning flange, thus preventing the transmission of vibration and improving the vibration isolation effect.

[0010] Preferably, both the first vibration isolation layer and the second vibration isolation layer refer to vibration isolation layers formed by compression of metal wires.

[0012] Preferably, the bushing hole of bushing one is clearance-fitted with the mounting shaft; the bushing hole of bushing two is clearance-fitted with the mounting shaft.

[0013] Preferably, the first vibration isolation layer and the second vibration isolation layer are respectively provided with through holes for passing through the mounting shaft; the through holes are transitionally fitted with the mounting shaft.

[0014] Positioning components one and two, which are in direct contact with the vibration-isolated object, are not in direct contact with the base and mounting shaft. Instead, they are positioned through vibration isolation layers one and two, which greatly reduces the transmission of external mechanical vibration to positioning components one and two, thereby improving the vibration isolation effect.

[0015] Preferably, the cap is threadedly connected to the mounting shaft for locking and fixing. The threaded connection between the cap and the mounting shaft allows for adjustment of the locking depth to accommodate various vibration isolation objects of different sizes.

[0016] Preferably, the cap and / or base has a through hole for disassembly and assembly. This through hole allows a tool to be inserted to rotate the cap or base, thereby disassembling and assembling the vibration isolator, further improving the ease of disassembly and assembly, and simplifying the structure and reducing the size of the vibration isolator.

This utility model vibration isolator can be used with various vibration isolation objects of different sizes, and has good versatility; 3. In this utility model vibration isolator, the positioning component one and positioning component two do not directly contact the base body and the mounting shaft, but are positioned by the vibration isolation layer one and vibration isolation layer two, which greatly reduces the transmission of external mechanical vibration to the positioning component one and positioning component two, thereby reducing the transmission of mechanical vibration to the vibration isolation object in contact with the positioning component one and positioning component two, and effectively improving the vibration isolation effect.

[0021] Specifically, both vibration isolation layer 1 2 and vibration isolation layer 2 5 preferably refer to vibration isolation layers formed by compression of metal wire (e.g., stainless steel wire).

[0022] A seat flange 9 is provided on the side of the seat 1 near the vibration isolation layer 2; a positioning flange 1 is provided on the side of the positioning member 3 near the vibration isolation layer 2; the seat flange 9 and the positioning flange 1 together position the vibration isolation layer 2; the sum of the height of the seat flange 9 and the height of the positioning flange 1 is less than the thickness of the vibration isolation layer 2, so that a gap 1 is left between the seat flange 9 and the positioning flange 1.

[0023] The cap 6 has a cap flange on the side near the vibration isolation layer 5; the positioning member 4 has a positioning flange 11 on the side near the vibration isolation layer 5; the cap flange and the positioning flange 11 together position the vibration isolation layer 5; the sum of the height of the cap flange and the height of the positioning flange 11 is less than the thickness of the vibration isolation layer 5, so that a gap 2 is left between the cap flange and the positioning flange 11.

[0024] This arrangement facilitates the positioning of the vibration isolation layer 1 2 between the base 1 and the positioning component 1 3, and the positioning of the vibration isolation layer 2 5 between the cap 6 and the positioning component 2 4; it also prevents the base flange 9 from contacting the positioning flange 1 and the cap flange from contacting the positioning flange 2 11, thus preventing the transmission of vibration and improving the vibration isolation effect.

[0025] Positioning component 3 is provided with bushing 10, and positioning component 3 passes through bushing 10 and is installed on mounting shaft 8; the sleeve hole of bushing 10 is clearance-fitted with mounting shaft 8.

[0027] Positioning component 3 and positioning component 4, which are in direct contact with the vibration isolation object, are not in direct contact with the base 1 and the mounting shaft 8. Instead, they are positioned through vibration isolation layer 2 and vibration isolation layer 5, which greatly reduces the transmission of external mechanical vibration to positioning component 3 and positioning component 4, thereby improving the vibration isolation effect.

[0028] The cap 6 is threaded to the mounting shaft 8 for locking and fixing. The cap 6 and the mounting shaft 8 are threaded together, and the locking depth can be adjusted to match various vibration isolation objects of different sizes.

The vibration isolator adopts a double vibration isolation layer structure, and the two vibration isolation layers are arranged coaxially. The two vibration isolation layers are located on both sides of the vibration isolation object, which work together to buffer vibration energy, improve vibration energy dissipation efficiency, and improve vibration isolation effect.
