Description

Technical Field

[0001] This utility model mainly relates to the field of vibration device technology, specifically to a U-shaped spring insulation structure. Background Technology

[0002] As a mechanical environment testing device, the electric vibration table is mainly used to verify the quality of products under mechanical conditions. With the continuous improvement of people's requirements for product quality, the electric vibration table is now widely used in various fields such as national defense, aviation, aerospace, communications, electronics, automobiles, and home appliances. Currently, the maximum stroke of the conventional vibration test table is 50mm and the maximum speed is 2m / s. However, for some special occasions, such as to verify the functionality and structural integrity of the equipment on or inside the aircraft of carrier-based aircraft when subjected to the impact of catapult takeoff and arrested landing, it has been found that the impact of catapult takeoff and arrested landing has the characteristics of transient, alternating, low frequency, large displacement, and high speed. The electric vibration table is required to have a maximum displacement of 400mm and a maximum speed of 6.5m / s. The ordinary electric vibration table cannot meet the requirements at present.

[0003] During the operation of specific embodiments, the inventors discovered the following defects:

[0004] In the existing technology, the U-shaped spring inside the vibration table is directly fixed to the insulating plate by bolts. The insulating plate is prone to cracking due to long-term vibration, which affects the insulation effect, leads to damage to the vibration device, and results in inaccurate test results, thus affecting product quality.

[0005] It should be noted that the above content falls within the scope of the inventor's technical knowledge. Due to the vast and complex nature of the technical content in this field, the above content of this application does not necessarily constitute prior art. Utility Model Content

[0007] This utility model provides a U-shaped spring insulation structure to solve the technical problems existing in the background art.

[0008] 2. Technical Solution:

[0009] To achieve the above objectives, the technical solution provided by this utility model is as follows: a U-shaped spring insulation structure, including an insulation plate, a water and electricity connector plate fixedly disposed on one side of the insulation plate, a plurality of U-shaped springs disposed on the other side of the water and electricity connector plate away from the insulation plate, a liner plate disposed at one end of the plurality of U-shaped springs away from the water and electricity connector plate, the water and electricity connector plate and the insulation plate being fixedly connected by a plurality of first bolts, the first bolts being covered with insulating bushings, and the liner plate being fixedly connected to the water and electricity connector plate by a plurality of second bolts.

[0010] Furthermore, one end of the U-shaped spring is disposed between the water and electricity connector plate and the liner plate, and the other end of the U-shaped spring away from the liner plate is provided with a U-spring conductive seat and a conductive pad. The U-spring conductive seat is fixed between the U-spring conductive seat and the conductive pad plate by a third bolt.

[0011] Furthermore, the first bolt, the second bolt, and the third bolt are all hexagon socket head cap screws.

[0012] Furthermore, the water and electricity connector plate has a protrusion, and a plurality of the first bolts are respectively disposed at the upper and lower ends of the protrusion. A water inlet is also provided in the middle of the water and electricity connector plate. The water and electricity connector plate, the liner plate, the U-spring conductive seat and the conductive pad are all made of conductive material.

[0013] Furthermore, the lower end of the U-spring conductive base is provided with a U-spring water-passing plate, and the U-spring water-passing plate is provided with a moving coil water inlet pipe. The two ends of the moving coil water inlet pipe are respectively connected to the U-spring water-passing plate and the water-electric connector plate, and the water inlet is connected to the moving coil water inlet pipe.

[0015] 3. Beneficial effects:

[0016] Compared with the prior art, the technical solution provided by this utility model has the following advantages:

[0017] The U-shaped spring insulation structure provided by this utility model has a U-shaped spring fixed to a water and electricity connector plate, which is then connected to an insulation plate. This avoids the U-shaped spring being directly connected to the insulation plate, thus preventing the risk of leakage. When the insulation plate ages and needs to be replaced, there is no need to disassemble the entire U-shaped spring structure, which facilitates maintenance and inspection. This improves the overall insulation effect of the equipment, increases its service life, and reduces assembly requirements, resulting in better insulation and lower equipment risk.
