Description

Technical Field

[0001] This utility model relates to the field of bidirectional sealing ring technology, and in particular to a bidirectional sealing ring. Background Technology

[0002] A bidirectional sealing ring is a ring-shaped sealing element that can achieve sealing in two directions. It is used in hydraulic systems, pneumatic systems, engineering machinery, and automobile manufacturing to prevent fluid from leaking in both directions between relatively moving parts or stationary connection points of equipment, thus ensuring the normal operation and efficiency of the system.

[0003] Traditional bidirectional sealing rings with elastic matrix will age and harden under long-term pressure and frequent temperature changes, resulting in a decline in sealing performance. The bonding strength between the reinforcing skeleton and the elastic matrix is ​​limited, and the two will peel off under equipment vibration or impact loads, further increasing the risk of leakage.

[0004] The current solution is to use composite elastic materials as the matrix and optimize the arrangement of the reinforcing skeleton to improve the aging resistance and structural stability of the sealing ring. However, the sealing ring will still wear out after repeated use of the equipment, and it is inconvenient to disassemble when replacing it, which reduces the maintenance efficiency of the operator. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a bidirectional sealing ring, which aims to improve the problem of inconvenience for operators to maintain and replace the sealing ring after it wears down in the prior art.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a bidirectional sealing ring, including a sealing lip, the outer wall of which is provided with a protective disassembly and assembly mechanism, and the left and right sides of the protective disassembly and assembly mechanism are provided with an installation mechanism, the installation mechanism is used for installing and fixing the sealing ring, and the front and rear sides of the installation mechanism are provided with locking components. The protective disassembly and assembly mechanism includes two housings. The inner walls of the two housings are fixedly installed on the outer wall of the sealing lip. Two limiting plates are fixedly connected to the front and rear sides of the two housings. Limiting grooves are opened in the middle of the multiple limiting plates. A disassembly bolt is threadedly connected to the inside of the right limiting plate. The end of the disassembly bolt is threadedly connected to the inner wall of the left limiting plate. A disassembly nut is threadedly connected to the left end of the outer wall of the disassembly bolt.

[0007] As a further description of the above technical solution: The mounting mechanism includes two rotating rods, the outer walls of which are rotatably connected to the inside of the housing. Connecting rods are fixedly connected to the front and rear sides of the two rotating rods, and a fixing plate is fixedly connected to the top of the connecting rods.

[0008] As a further description of the above technical solution: A metal reinforcing ring is fixedly installed on the inner center of the sealing lip, and the metal reinforcing ring adopts a ring plate design.

[0009] As a further description of the above technical solution: The protective disassembly and assembly mechanism also includes a carbon fiber wear-resistant liner, the bottom end of which is fixedly connected to the inner side of the sealing lip.

[0010] As a further description of the above technical solution: The locking assembly includes two locking plates, with each of the two locking plates fixedly connected to the front and rear sides of the fixed plate on adjacent sides. Each of the two locking plates has a locking groove in the middle, and each of the two locking plates has a locking bolt threaded to its right side. A locking nut is threaded to the left side of each locking bolt.

[0011] As a further description of the above technical solution: A helical spring is fixedly installed on the upper and lower ends of the inner side of the sealing lip, and the adjacent sides of the helical spring are fixedly connected to the upper and lower ends of the carbon fiber wear-resistant liner.

[0012] As a further description of the above technical solution: Two limiting rings are fixedly connected to the upper and lower ends of the sealing lip, and the two limiting rings are symmetrically designed.

[0013] As a further description of the above technical solution: The protective disassembly and assembly mechanism also includes multiple heat dissipation holes, which are respectively formed on the outer wall of the housing.

[0014] This utility model has the following beneficial effects: 1. In this utility model, when disassembling the sealing ring, the outer shell of the disassembly mechanism is protected, a limiting plate is connected, and the disassembly bolt is fixed through the limiting groove. By unscrewing the disassembly nut, the disassembly mechanism is separated from the disassembly bolt, and the fixing of the limiting plate is released, thereby realizing the rapid disassembly of the outer shell, improving maintenance efficiency, and avoiding the problem of cumbersome and time-consuming disassembly of the sealing ring.

[0015] 2. In this utility model, when installing the sealing ring, a connecting rod connected by a rotating rod is used to connect the fixing plate. The rotation of the rotating rod drives the rotation of the connecting rod, which in turn drives the rotation of the fixing plate. The angle of the fixing plate is adjusted so that it fits with the external device. The fixing plate is fixed by a locking component, thereby realizing the installation of the sealing ring. This avoids the need for additional devices during installation and avoids problems such as fixed installation angle and poor adaptability of the sealing ring. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Reference Figure 1 , Figure 4 and Figure 5 The present invention provides an embodiment of a bidirectional sealing ring, comprising a sealing lip 1, which serves as the core sealing component of the bidirectional sealing ring and achieves a bidirectional sealing function. The outer wall of the sealing lip 1 is provided with a protective disassembly and assembly mechanism 2, which protects the sealing lip 1 and facilitates the disassembly and assembly of the overall structure. The protective disassembly and assembly mechanism 2 is provided with an installation mechanism 3 on both the left and right sides, which cooperates with an external device to achieve the installation and positioning of the sealing ring. The installation mechanism 3 is used for the installation and fixing of the sealing ring. The front and rear sides of the installation mechanism 3 are provided with locking components 304 to enhance the stability of the connection between the installation mechanism 3 and the external device. The protective disassembly mechanism 2 includes two outer shells 201 that wrap around and protect the outer wall of the sealing lip 1. The inner walls of the two outer shells 201 are fixedly installed on the outer wall of the sealing lip 1. Two limiting plates 202 are fixedly connected to the front and rear sides of the two outer shells 201 to provide support for the installation of other components. The middle of the multiple limiting plates 202 is provided with limiting grooves 203 to accommodate and limit the disassembly bolts 204. The internal thread of the right limiting plate 202 is connected to the disassembly bolts 204 to realize the detachable connection between the two limiting plates 202. The end of the disassembly bolts 204 is threaded to the inner wall of the left limiting plate 202. The left end of the outer wall of the disassembly bolts 204 is threaded to the disassembly nut 205 to enhance the tightness of the connection between the disassembly bolts 204 and the left limiting plate 202.

[0020] Specifically, the sealing lip 1, as the core sealing component, achieves a bidirectional sealing function. The two outer shells 201 of the protective disassembly and assembly mechanism 2, fixedly installed on the outer wall of the sealing lip 1, protect it from impurities and external forces, preventing erosion and impact. This also facilitates disassembly. The installation mechanisms 3, located on both the left and right sides of the protective disassembly and assembly mechanism 2, cooperate with external devices to install and fix the entire bidirectional sealing ring in the required position. Locking components 304, located on both the front and rear sides of the installation mechanism 3, secure the installation mechanism 3 to the external device, preventing loosening or displacement of the sealing ring during use and ensuring stable bidirectional sealing. When disassembling the bidirectional sealing ring, the two outer shells 201 of the protective disassembly and assembly mechanism 2 are used to install and fix the sealing ring in the required position. The outer shell 201 of the protective disassembly and assembly mechanism 2, which is fixedly installed on the outer wall of the sealing lip 1, protects the sealing ring. The limiting plate 202, which is fixedly connected to the front and rear sides of the outer shell 201, provides a support for the installation of the disassembly bolt 204. The limiting groove 203 opened in the middle of the limiting plate 202 fixes the position of the disassembly bolt 204 to prevent it from shifting during use. The disassembly bolt 204 is connected to the inner thread of the right limiting plate 202, and its end is connected to the inner wall of the left limiting plate 202. The disassembly nut 205, which is connected to the end of the outer wall of the disassembly bolt 204, enables the connection and disassembly of the disassembly bolt 204 and the limiting plate 202, thereby completing the disassembly operation and realizing convenient replacement of the bidirectional sealing ring.

[0021] Reference Figure 1 , Figure 2 and Figure 6 The installation mechanism 3 includes two rotating rods 301. The outer walls of the two rotating rods 301 are rotatably connected to the inside of the outer shell 201. Connecting rods 302 are fixedly connected to the front and rear sides of the two rotating rods 301. A fixing plate 303 is fixedly connected to the top of the connecting rods 302. A metal reinforcing ring 4 is fixedly installed in the middle of the inner side of the sealing lip 1. The metal reinforcing ring 4 adopts a ring plate design. The protective disassembly and assembly mechanism 2 also includes a carbon fiber wear-resistant liner 5. The bottom end of the carbon fiber wear-resistant liner 5 is fixedly connected to the inner side of the sealing lip 1.

[0022] Specifically, during the installation of the sealing ring, the two rotating rods 301 of the installation mechanism 3, which are rotatably connected inside the housing 201, drive the entire installation mechanism 3 to rotate, adjusting the installation angle. The connecting rods 302, which are fixedly connected to both the front and rear sides of the rotating rods 301, connect to the fixing plate 303, transmitting the rotation of the rotating rods 301 to the fixing plate 303. The fixing plate 303, which is fixedly connected to the top of the connecting rods 302, contacts the external device and achieves connection and fixation, improving the adaptability of the installation. The metal reinforcing ring 4, which is fixedly installed in the middle of the inner side of the sealing lip 1, adopts a ring plate design to enhance the overall rigidity of the sealing ring and prevent excessive deformation during high-frequency movement. The carbon fiber wear-resistant gasket 5 of the protective disassembly and assembly mechanism 2, which is fixedly connected to the inner side of the sealing lip 1, reduces the wear between the inner side of the sealing lip 1 and the contact parts, extending the service life of the sealing lip 1.

[0023] Reference Figure 1 , Figure 2 and Figure 3 The locking assembly 304 includes two locking plates 3041. The adjacent sides of the two locking plates 3041 are fixedly connected to the front and rear sides of the fixing plate 303. The middle of the two locking plates 3041 is provided with a locking groove 3044. The right side of the two locking plates 3041 is threaded with a locking bolt 3042, and the left side of the locking bolt 3042 is threaded with a locking nut 3043.

[0024] Specifically, the locking plate 3041 of the locking assembly 304, which is fixedly connected to both the front and rear sides of the fixing plate 303, forms an integral structure with the fixing plate 303, providing a stable foundation for the locking operation. The locking groove 3044 in the middle of the locking plate 3041 fixes the position of the locking bolt 3042. The locking bolt 3042, which is threaded on the right side of the locking plate 3041, passes through the right locking plate 3041 and extends to the left side, locking the two locking plates 3041. The locking nut 3043, which is threaded on the left side of the locking bolt 3042, fixes the locking bolt 3042, thereby locking the fixing plate 303 and fixing it to the external device, thus ensuring the stability of the entire bidirectional sealing ring after installation.

[0025] Reference Figure 2 , Figure 3 and Figure 4 A helical spring 6 is fixedly installed on the upper and lower ends of the inner side of the sealing lip 1. The adjacent side of the helical spring 6 is fixedly connected to the upper and lower ends of the carbon fiber wear-resistant liner 5. Two limit rings 7 are fixedly connected to the upper and lower ends of the sealing lip 1. The two limit rings 7 are symmetrically designed. The protective disassembly and assembly mechanism 2 also includes multiple heat dissipation holes 8, which are respectively opened on the outer wall of the outer shell 201.

[0026] Specifically, the elasticity of the helical springs 6, which are fixedly installed at both the upper and lower ends of the inner side of the sealing lip 1, continuously applies pressure to the sealing lip 1, ensuring that the sealing lip 1 always fits tightly against the surface of the external device and ensuring a sealing effect. The two limiting rings 7, which are fixedly connected at both the upper and lower ends of the sealing lip 1, limit the axial displacement of the sealing ring on the external device and ensure a stable sealing position. The heat generated by friction is dissipated through the multiple heat dissipation holes 8 opened on the outer wall of the housing 201, preventing heat accumulation from affecting the performance of the sealing lip 1.

[0027] Working principle: When using the device, the sealing lip 1 is connected to the external device. Simultaneously, the carbon fiber wear-resistant gasket 5 reduces wear on the inner side of the sealing lip 1, extending its service life. The housing 201 protects the sealing lip 1, and the heat dissipation holes 8 inside the housing 201 dissipate heat generated during friction, preventing performance degradation due to overheating. The locking assembly 304 secures the mounting mechanism 3, installing the sealing ring onto the external device. The limiting ring 7 restricts axial displacement of the sealing ring, ensuring a stable sealing position. When using a sealing ring, the rigidity of the sealing lip 1 is enhanced by a metal reinforcing ring 4 to prevent excessive deformation and failure of the sealing lip 1 during high-frequency movement. The elastic pressure provided by the helical spring 6 ensures that the sealing lip 1 always fits against the sealing surface, improving the reliability of the seal. After the sealing operation is completed, the sealing ring can be quickly disassembled by the protective disassembly and assembly mechanism 2. During disassembly, the limit plate 202 is quickly separated by the threaded engagement of the disassembly bolt 204 and the disassembly nut 205, thereby disassembling the outer shell 201 and the sealing ring, which facilitates the replacement and maintenance of the sealing ring. Furthermore, during the installation of the sealing ring, the angle of the fixing plate 303 is adjusted by rotating the rotating rod 301. The locking plate 3041 is fixed by the threaded engagement of the locking bolt 3042 and the locking nut 3043 of the locking assembly 304, thereby fixing the fixing plate 303, so that it fits the external device better, improving the adaptability of the sealing ring and completing the installation operation.
