Description

Technical Field

[0001] This utility model relates to the field of aerospace engineering technology, specifically a sealing ring with good sealing effect. Background Technology

[0002] Aircraft seals are widely used, from hydraulic systems to pneumatic systems, from engines to landing gear. They are ubiquitous, ensuring the sealing of each system and preventing fluid leakage and the intrusion of external contaminants. Although aircraft seals are seemingly small components, they play a vital role in the safety and performance of aircraft.

[0003] According to the announcement number CN221762605U, entitled "A seal with good sealing effect, including a sealing ring body", the research and analysis found that although the sealing ring body has the advantages of better sealing effect and slower aging, it also has the following disadvantages to a certain extent.

[0004] For example, sealing rings often lack a tensioning structure, making it impossible to tension and seal the sealing ring. Gaps can easily form between the sealing ring and the connecting parts, making it impossible to accurately fill and adapt to various tiny gaps between the sealing surfaces, thus affecting the sealing effect of the sealing ring. Utility Model Content

[0005] The purpose of this invention is to provide a sealing ring with good sealing effect, which has the advantages of improving the elastic deformation ability of the sealing ring and adapting to the deformation of the sealing surface, and maintaining the stability of the sealing effect.

[0008] The adjustment mechanism includes a cavity, which is formed on the inner wall of the sealing ring body. A support plate is movably connected to the inner wall of the cavity. A support rod and a return spring are fixedly installed on one side of the support plate. One end of the support rod passes through the sealing ring body and is fixedly installed with a sealing inner ring.

[0009] Preferably, the surface of the connecting plate is provided with a threaded groove, and one end of the bolt passes through the threaded groove and is threadedly connected to the inner wall of the threaded groove.

[0010] Preferably, the end of the return spring away from the support plate is fixedly connected to the inner wall of the cavity, and the return spring is movably sleeved on the surface of the support rod.

[0011] Preferably, the support rod and the inner sealing ring are in movable contact with the inner wall of the sealing ring body, and the number of support rods is several.

[0012] Preferably, the surface of the sealing ring body is provided with an installation groove, and a pressure ridge is embedded in the inner wall of the installation groove, and the pressure ridge is fixedly installed on the inner wall of the outer shell.

[0013] Preferably, the connecting plates are in movable contact on opposite sides, and the connecting plates are located on both sides of the outer casing.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0015] 1. This utility model utilizes the combination of a cavity, a support plate, a support rod, a return spring, and a sealing inner ring. The sealing ring is made of a highly elastic material and can undergo elastic deformation under system pressure, tightly fitting the sealing surface. It can adapt to minor deformations under different working conditions, such as vibration and impact, ensuring the stability and durability of the sealing effect.

[0016] 2. This utility model adopts a modular design that is easy to disassemble and replace through the cooperation of threaded grooves, mounting grooves, pressure ridges, outer shell, connecting plate and bolts. The addition of structural elements such as pressure ridges and bolts to the design improves the structural strength of the outer shell and enhances the overall structural performance.

[0022] Please see Figures 1-4 A sealing ring with good sealing effect includes a sealing ring body 1, a shell 2 is provided on the surface of the sealing ring body 1, a connecting plate 3 is welded to the surface of the shell 2, a bolt 4 is provided through the surface of the connecting plate 3, and an adjustment mechanism 5 is provided on the inner wall of the sealing ring body 1.

[0023] The adjusting mechanism 5 includes a cavity 6, which is opened in the inner wall of the sealing ring body 1. A support plate 7 is movably connected to the inner wall of the cavity 6. A support rod 8 and a return spring 9 are fixedly installed on one side of the support plate 7. One end of the support rod 8 passes through the sealing ring body 1 and is fixedly installed with a sealing inner ring 10.

[0024] Please see Figure 1 and Figure 3 The surface of the connecting plate 3 is provided with a threaded groove 11. One end of the bolt 4 passes through the threaded groove 11 and is threadedly connected to the inner wall of the threaded groove 11. By setting the threaded groove 11, the basic method of connection and fixation is realized, and the components can be tightly connected together.

[0025] Please see Figure 4 The end of the return spring 9 away from the support plate 7 is fixedly connected to the inner wall of the cavity 6. The return spring 9 is movably sleeved on the surface of the support rod 8. By setting the return spring 9, the equipment or device can be restored to the initial position or state after the external force is removed.

[0026] Please see Figure 2 and Figure 4 The support rod 8 and the inner sealing ring 10 are in movable contact with the inner wall of the sealing ring body 1, respectively. There are several support rods 8. By setting the support rods 8, the support, fixation and connection functions are provided, and the connection between different components is realized.

[0027] Please see Figure 2 and Figure 3 The surface of the sealing ring body 1 is provided with an installation groove 12, and a pressure ridge 13 is inlaid in the inner wall of the installation groove 12. The pressure ridge 13 is fixedly installed in the inner wall of the outer shell 2. By setting the installation groove 12, stable and precise guidance and support are provided to ensure that the moving parts in the equipment can be placed according to the predetermined trajectory.

[0028] Please see Figure 3 The connecting plates 3 are in active contact on opposite sides. The connecting plates 3 are located on both sides of the outer shell 2. By setting the connecting plates 3, the load-bearing capacity and stability of the structure are enhanced, the load is distributed, and the overall durability is improved.

[0029] When in use, the user first installs the sealing ring body 1 on the equipment. The inner sealing ring 10 will be squeezed, causing its material to deform. This pushes the support rod 8 to stretch the return spring 9 through the support plate 7. The greater the tension on the return spring 9, the more the rebound force generated by the multiple sets of return springs 9 inside will buffer, limit, and strengthen the inner sealing ring 10. This makes the inner sealing ring 10 on the inside of the sealing ring body 1 fit more tightly with the equipment mating surface, resulting in a better sealing effect.

[0030] Under lateral pressure and other loads, the pressure ridge 13 does not shift. It is individually installed to the position corresponding to the mounting groove 12 on one side, so that the outer shell 2 is completely fastened to the surface of the sealing ring body 1. The connecting plates 3 are attached to each other. Then, the bolt 4 is rotated to engage with the threaded groove 11 on the surface of the connecting plate 3, thereby assembling and locking the outer shell 2, improving the external protection of the sealing ring body 1. With the compression of the inner lining pressure ridge 13, the sealing ring body 1 is compressed and sealed, ensuring the stability and durability of the sealing effect.

[0031] In summary, this sealing ring with good sealing effect solves the problem of not being able to form a tight sealing interface and thus failing to meet the requirements of high-efficiency sealing and long-term durability through the cooperation of the sealing ring body 1, the outer shell 2, the connecting plate 3, the bolt 4 and the adjusting mechanism 5.
