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.

[0024] Specific implementation examples are given below.

[0025] Please see Figures 1-5This utility model provides an assembled metal elliptical ring gasket, including an inner ring 1; the outer wall of the inner ring 1 is wound with a metal sealing material 2, the outer wall of the metal sealing material 2 contacts a first outer ring strip 3, the end of the first outer ring strip 3 contacts a second outer ring strip 4, the end of the first outer ring strip 3 has an insertion groove 31, the end of the second outer ring strip 4 has a rectangular groove 41, a connecting component is provided in the middle of the insertion groove 31, the connecting component includes an insertion block 51, the insertion block 51 is inserted into the middle of the insertion groove 31, and a rectangular shell 52 is fixed to the end of the insertion block 51, the rectangular shell 52 is inserted into the rectangular groove 41. In the middle of the rectangular shell 52, a connecting plate 58 is slidably connected. A limiting block 53 is fixedly connected to the top of the end of the connecting plate 58. The limiting block 53 is slidably connected to the top of the rectangular shell 52. A limiting groove 42 is opened in the middle of the rectangular groove 41. The top of the limiting block 53 is inserted into the middle of the limiting groove 42. A rectangular strip 56 is fixedly connected to the top of the other end of the connecting plate 58. The rectangular strip 56 is slidably connected to the top of the insertion block 51. During operation, when assembling the metal elliptical ring, the metal sealing material 2 can be wrapped around the outer wall of the inner ring 1 using equipment. Then, multiple sets of first outer ring strips 3 are... The second outer ring 4 is fitted onto the outer wall of the metal sealing material 2. During the special process, the distance between multiple sets of first outer ring 3 and second outer ring 4 can be adjusted. Simply push the push block 5, which will move the rectangular bar 56. The rectangular bar 56 will move the connecting plate 58. While the connecting plate 58 is compressing the spring 59, it will also move the limiting block 53 until the limiting block 53 disengages from the middle of the limiting groove 42. At this point, the first outer ring 3 can be pulled to change the connection distance between it and the second outer ring 4 until the limiting block 53 coincides with another set of limiting grooves 42. Then, the push block 5 can be released, and the spring 59 will release. 9 will push the connecting plate 58 to reset through its own elasticity, and the limiting block 53 will also reset accordingly and be inserted into the middle of the limiting groove 42. In this way, when the first outer ring 3 and the second outer ring 4 are connected together, the distance between them will change. The elliptical ring formed by multiple sets of first outer ring 3 and second outer ring 4 can be easily fitted onto the outside of the metal sealing material 2. After the fitting is completed, push the first outer ring 3 or the second outer ring 4 to make them merge. In this way, it can be fixedly stuck on the outer wall of the metal sealing material 2 without the need for workers to install it by hammering with tools, which improves convenience.

[0026] Furthermore, such as Figures 3-4As shown, a bolt 54 is threadedly connected to the side wall of the end of the first outer ring 3. A threaded hole 55 is provided on the side wall of the insertion block 51. The end of the bolt 54 is threaded into the middle of the threaded hole 55. A convex groove 32 is provided on the side wall of the end of the first outer ring 3. The other end of the bolt 54 contacts the middle of the convex groove 32. During operation, if wear occurs after the first outer ring 3 and the second outer ring 4 have been used for a period of time, and replacement of the first outer ring 3 or the second outer ring 4 is required, a tool can be used to rotate the bolt 54 to disengage it. Press the push block 5 to release the limit block 53 in the middle of the threaded hole 55, and pull the rectangular shell 52 out of the rectangular groove 41. Then, push the rectangular shell 52 to move the plug block 51 so that it is disengaged from the middle of the plug groove 31. In this way, the first outer ring 3 or the second outer ring 4 can be replaced. During installation, simply insert the plug block 51 completely into the middle of the plug groove 31, and then turn the bolt 54 to insert it into the middle of the threaded hole 55. In this way, when replacing the outer ring, it is not necessary to replace the whole ring, which reduces the replacement cost.

[0027] Furthermore, such as Figure 5 As shown, a spring 59 is fixedly connected to the bottom of the connecting plate 58. The bottom of the spring 59 is fixedly connected to the middle of the rectangular shell 52. When working, the spring 59 has a certain elasticity, which ensures that the connecting plate 58 will not squeeze the spring 59 and drive the limiting block 53 to move without pushing the push block 5, thus ensuring the stability of the limiting block 53.

[0028] Furthermore, such as Figure 4 As shown, a sealing groove 43 is provided at the end of the second outer ring 4, and a first sealing strip 33 is fixedly connected to the end of the first outer ring 3. The first sealing strip 33 contacts the middle of the sealing groove 43. During operation, when the first outer ring 3 and the second outer ring 4 are combined, the first sealing strip 33 will be inserted into the middle of the sealing groove 43 to ensure the sealing of the connection between the first outer ring 3 and the second outer ring 4.

[0029] Furthermore, such as Figures 4-5 As shown, a push block 5 is fixedly connected to the top of the rectangular strip 56. The outer wall of the push block 5 contacts the middle of the insertion groove 31. A second sealing strip 57 is fixedly connected to the side wall of the push block 5. The second sealing strip 57 contacts the middle of the sealing groove 43. During operation, the second sealing strip 57 and the first sealing strip 33 are combined to fill the middle of the sealing groove 43, thereby further ensuring the sealing performance of the connection end between the first outer ring strip 3 and the second outer ring strip 4.

[0030] Furthermore, such as Figures 4-5As shown, the top of the limiting block 53 is set as an inclined surface. During operation, the inclined surface ensures that when the first outer ring 3 and the second outer ring 4 are combined, only pushing is required, which improves convenience.

[0031] Furthermore, such as Figures 1-3 As shown, multiple sets of the connecting components, insertion grooves 31, convex grooves 32, and first sealing strips 33 are provided, and multiple sets of connecting components, insertion grooves 31, convex grooves 32, and first sealing strips 33 are located at the other end of the second outer ring strip 4. Multiple sets of rectangular grooves 41, limiting grooves 42, and sealing grooves 43 are provided, and multiple sets of rectangular grooves 41, limiting grooves 42, and sealing grooves 43 are located at the other end of the first outer ring strip 3. During operation, the multiple sets of connecting components, insertion grooves 31, convex grooves 32, and first sealing strips 33, along with the multiple sets of rectangular grooves 41, limiting grooves 42, and sealing grooves 43, enable quick assembly, disassembly, and adjustment between the multiple sets of first outer ring strips 3 and second outer ring strips 4, improving convenience.

[0032] Working principle: When assembling the metal elliptical ring, the equipment can be used to wrap the metal sealing material 2 around the outer wall of the inner ring 1. Then, multiple sets of first outer ring strips 3 and second outer ring strips 4 are fitted onto the outer wall of the metal sealing material 2. During the process, the distance between the multiple sets of first outer ring strips 3 and second outer ring strips 4 can be adjusted. Simply push the push block 5, which will drive the rectangular strip 56 to move. The rectangular strip 56 will drive the connecting plate 58 to move. While the connecting plate 58 is compressing the spring 59, it will drive the limiting block 53 to move until the limiting block 53 is disengaged from the middle of the limiting groove 42. At this time, the first outer ring strip 3 can be pulled to change the connection distance between it and the second outer ring strip 4 until the limit is reached. When block 53 aligns with another set of limiting grooves 42, push block 5 can be released. At this time, spring 59 will push connecting plate 58 to reset through its own elasticity, and limiting block 53 will also reset and insert into the middle of limiting groove 42. In this way, while ensuring that the first outer ring 3 and the second outer ring 4 are connected together, the distance between them will change. The elliptical ring formed by multiple sets of first outer ring 3 and second outer ring 4 can be easily fitted onto the outside of metal sealing material 2. After fitting, push the first outer ring 3 or the second outer ring 4 to make them merge. In this way, it can be fixedly stuck on the outer wall of metal sealing material 2 without the need for workers to use tools to hammer it, which improves convenience.

[0033] If the first outer ring 3 and the second outer ring 4 wear out after a period of use and need to be replaced, a tool can be used to rotate the bolt 54 to disengage it from the center of the threaded hole 55. The push block 5 is then pressed to release the limiting block 53, and the rectangular shell 52 is pulled out of the rectangular groove 41. Subsequently, the rectangular shell 52 can be pushed to move the plug block 51, disengaging it from the center of the plug groove 31. This allows the first outer ring 3 or the second outer ring 4 to be replaced. During installation, the plug block 51 is fully inserted into the center of the plug groove 31, and then the bolt 54 is rotated to insert it into the center of the threaded hole 55. This eliminates the need to replace the entire outer ring, reducing replacement costs.

[0034] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
