The appearance of the phrase in various locations in the specification does not necessarily refer to the same embodiment, nor is it an independent or alternative embodiment that is mutually exclusive with other embodiments. It is explicitly and implicitly understood by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0020] The utility model embodiment provides a sealing ring which is easy to disassemble, such as Figure 1-3 As shown, the seal ring that is easy to disassemble includes: a seal ring body 1, a first annular cavity 2 is formed on the seal ring body 1, and a plurality of through holes 5 are formed on the top inner wall of the first annular cavity 2; an annular block 3 fixedly mounted on the inner wall of the first annular cavity 2, and a second annular cavity 4 is formed on the annular block 3; and a plurality of tightening mechanisms mounted on the annular block 3 for tightening the seal ring body 1.

[0021] In this embodiment, the core component includes a sealing ring body 1, on which a first annular cavity 2 is cleverly opened, and a plurality of through holes 5 are provided on the top inner wall of the first annular cavity 2, which provide convenience for subsequent disassembly operations. In addition, an annular block 3 is fixedly installed on the inner wall of the first annular cavity 2, and a second annular cavity 4 is further opened on the annular block 3. This design not only enhances the structural stability of the sealing ring, but also provides a basis for the subsequent installation of a tightening mechanism. More importantly, the utility model installs a plurality of tightening mechanisms on the annular block 3, which can realize the tightening of the sealing ring body 1, and ensure the sealing between the filling nozzle and the container mouth when filling with liquid nitrogen. When disassembly is required, the sealing ring body 1 can be easily removed from the equipment by operating these tightening mechanisms, thereby avoiding the damage problem that may occur during the disassembly of the traditional sealing ring.

[0022] In a further preferred embodiment of the utility model, the tensioning mechanism includes: a screw sleeve 6 slidably mounted on the annular block 3; a screw rod 7 rotatably mounted on the inner wall of the second annular cavity 4, the screw rod 7 being threadedly connected to the screw sleeve 6; a pressure strip 8 welded on the screw sleeve 6, one side of the pressure strip 8 being fixedly connected to the inner wall of the first annular cavity 2; a rotating shaft 9 rotatably mounted on the inner wall of the top of the second annular cavity 4, the top end of the rotating shaft 9 extending to the interior of the through hole 5; a first bevel gear 10 fixedly mounted on the rotating shaft 9; a second bevel gear 11 fixedly mounted on the screw rod 7, the second bevel gear 11 being meshed with the first bevel gear 10.

[0023] In this embodiment, the tensioning mechanism mainly includes a screw sleeve 6, a screw rod 7, a pressure strip 8, a rotating shaft 9, a first bevel gear 10 and a second bevel gear 11. The screw sleeve 6 is slidably mounted on the annular block 3, and the screw rod 7 is rotatably mounted on the inner wall of the second annular cavity 4 and is threadedly connected with the screw sleeve 6. This design enables the screw sleeve 6 to move along its axial direction when the screw rod 7 rotates, and the screw sleeve 6 will drive the pressure strip 8 to move, thereby achieving the compression or loosening of the sealing ring body 1. This design is not only simple in structure, but also can effectively ensure the sealing effect. More cleverly, the utility model also introduces The combination of the rotating shaft 9, the first bevel gear 10 and the second bevel gear 11, the rotating shaft 9 is rotatably mounted on the top inner wall of the second annular cavity 4, and its top end extends to the inside of the through hole 5, which is convenient for external operation. The first bevel gear 10 is fixedly sleeved on the rotating shaft 9, and the second bevel gear 11 is fixedly sleeved on the screw 7, and the two are meshed with each other. In this way, when the rotating shaft 9 is rotated, the first bevel gear 10 will drive the second bevel gear 11 to rotate, and then drive the screw 7 to rotate. This design makes the operation of the tensioning mechanism more convenient. The user only needs to rotate the rotating shaft 9 to tighten or loosen the sealing ring.

[0024] In a further preferred embodiment of the present invention, a plurality of slide bars 12 are slidably mounted on the annular block 3 , and one end of the plurality of slide bars 12 is fixedly connected to one side of the plurality of pressure strips 8 .

[0025] In this embodiment, the provision of the slide bar 12 ensures the stability and linearity of the pressure strip 8 during movement, effectively preventing the pressure strip 8 from being offset or twisted during movement, thereby further ensuring smooth disassembly of the sealing ring body 1.

[0026] In a further preferred embodiment of the present invention, round blocks 13 are fixedly mounted on the top ends of the plurality of rotating shafts 9 , and diamond-shaped grooves 14 are formed on the top ends of the plurality of round blocks 13 .

[0027] In this embodiment, the design of the diamond-shaped groove 14 allows an operator to insert a special tool (such as a screwdriver, etc.) into the groove, thereby making it easier to rotate the round block 13 and the rotating shaft 9.

[0028] In a further preferred embodiment of the present invention, a plurality of sealing teeth 15 are arranged on the inner side of the sealing ring body 1, and the plurality of sealing teeth 15 are all arranged in a ring shape.

[0029] In this embodiment, the provision of the sealing teeth 15 can effectively fill the tiny gap between the filling nozzle and the container mouth, thereby preventing leakage of liquid nitrogen during the filling process. Since the sealing teeth 15 adopt an annular design, they can be evenly distributed on the inner side of the sealing ring body to form a complete sealing ring, further enhancing the sealing effect. In addition, the sealing teeth 15 can also increase the friction between the sealing ring and the filling nozzle, making the sealing ring less likely to fall off or shift when subjected to external force, thereby ensuring the stability and safety of the filling process.

[0030] In a further preferred embodiment of the present invention, the thickness of the sealing ring body 1 is not less than 1 cm, and the sealing ring body 1 is made of rubber.

[0031] In this embodiment, the thickness of the sealing ring body 1 is set to be no less than 1 cm. This design choice is based on the needs in practical applications. A thicker sealing ring body 1 can provide better sealing performance and structural stability, and effectively resist the influence of external forces and temperature changes on the sealing ring. At the same time, sufficient thickness can also ensure that the sealing ring is not easily deformed or damaged during the disassembly process, thereby extending its service life. In addition, we have selected rubber as the material of the sealing ring body 1. The rubber material has good elasticity and wear resistance, and can adapt to the sealing requirements between filling nozzles and container mouths of different shapes and sizes. At the same time, the rubber material also has certain corrosion resistance and low temperature resistance, and can maintain a stable working state in harsh environments such as liquid nitrogen filling.

[0032] In a further preferred embodiment of the present invention, the slide bar 12 is configured to be cylindrical, and the plurality of round blocks 13 are all made of stainless steel.

[0033] In this embodiment, the plurality of round blocks 13 are all made of stainless steel, which has excellent corrosion resistance and wear resistance and can maintain long-term stability and durability in harsh working environments.

[0034] In summary, compared with the related art, the seal ring provided by the utility model, which is easy to disassemble, realizes a more efficient and convenient disassembly operation as a whole, while ensuring excellent sealing performance and structural stability. Through the design of the tension mechanism, the disassembly process of the seal ring body 1 is simpler, reducing the difficulty of operation and the risk of damage to the seal ring body 1. In addition, the thickness and material selection of the seal ring body 1 further enhance the durability and practicality of the seal ring body 1. Therefore, the seal ring body 1 of the utility model has significant application advantages in occasions such as liquid nitrogen filling machines that require efficient and stable sealing, and can save maintenance costs for enterprises.
