Description

Technical Field

[0001] This utility model belongs to the field of sealing ring technology, specifically a metal sealing ring structure. Background Technology

[0002] Sealing rings are generally classified into O-rings, rectangular rings, U-rings, Y-rings, XY-rings, etc. The choice of sealing ring material is of great significance to its sealing performance and service life. The performance of the material directly affects the performance of the sealing ring. Metal sealing rings are generally sealing rings that combine metal and rubber. The metal serves as the core of the sealing ring and has advantages such as high sealing strength, good effect, and reusability.

[0003] Patent CN219549582U discloses a metal C-type sealing ring, comprising an outer sealing ring and an inner sealing ring. The inner sealing ring is threadedly connected to the outer sealing ring. An outer groove is formed through the outer sealing ring, and an inner groove is formed through the outer sealing ring within the outer groove. A secondary groove is formed through the inner sealing ring. The inner sealing ring is threadedly connected to the outer sealing ring, and the opening edge of the inner sealing ring is tightly sealed to the inner wall of the outer sealing ring, thus forming a seal. When the assembled sealing ring is fitted onto the object to be sealed, since the inner sealing ring is placed inside the outer sealing ring and the inner groove is placed inside the outer groove, the secondary ring is placed inside the rubber ring, and the rubber ring is placed inside the ring. At this time, the top walls of the secondary ring, the rubber ring, and the ring are in close contact with the surface of the object. Thus, the combined action of the secondary ring, the rubber ring, and the ring prevents leakage and improves the overall sealing performance of the component.

[0004] While the aforementioned device can improve the overall sealing performance of the components, the sealing ring needs to be replaced after prolonged use. However, since the sealing ring is embedded in the metal ring, it is not easy to remove, making the replacement process cumbersome and reducing ease of use. Therefore, we provide a metal sealing ring structure to solve these problems. Utility Model Content

[0023] 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.

[0024] like Figures 1 to 8As shown, this utility model provides a metal sealing ring structure, including a metal ring 1, with a sealing ring 4 sleeved inside the metal ring 1. The upper and lower surfaces of the sealing ring 4 can contact and seal the upper and lower surfaces of the metal ring 1, thereby ensuring the sealing effect between the two shaft connecting parts. A notch 3 is provided on one side of the metal ring 1, and a positioning block 2 is engaged with the metal ring 1 through the notch 3. After the positioning block 2 is engaged in the notch 3, it can form a whole with the metal ring 1. Both the positioning block 2 and the inner ring of the metal ring 1 have inner grooves 7. A protruding rubber ring 6 is fixedly connected to the inner wall of the sealing ring 4, and the protruding rubber ring 6 is inserted into the inner groove 7. The arrangement of the protruding rubber ring 6 and the inner groove 7 ensures the stability of the sealing ring 4 after being sleeved, preventing its deformation. The positioning block 2 is provided with a function for engaging with the metal ring 1. The positioning mechanism connected to the protruding rubber ring 6 facilitates the fixing of the sealing rubber ring 4 onto the positioning block 2. In specific operation, simply squeeze the two sides of the sealing rubber ring 4 towards the center, then pull the positioning block 2 outward to separate the sealing rubber ring 4 from the metal ring 1. Then release the positioning between the sealing rubber ring 4 and the positioning block 2 to re-fix the new sealing rubber ring 4 onto the positioning block 2. When the sealing rubber ring 4 is fitted onto the metal ring 1, simply squeeze the two sides of the sealing rubber ring 4 towards the center, then insert the sealing rubber ring 4 directly into the center of the metal ring 1, and then snap the positioning block 2 into the notch 3. This ensures that the sealing rubber ring 4 can be securely fitted onto the metal ring 1 and the positioning block 2, making the installation and removal of the sealing rubber ring 4 more flexible and convenient.

[0025] like Figure 3 , Figure 4 , Figure 7 and Figure 8 As shown, the positioning mechanism includes a mounting groove 9, which is formed on the positioning block 2. The positioning block 2 has a positioning hole 11 in its inner ring. A positioning shaft 8 is inserted into the mounting groove 9, and the bottom end of the positioning shaft 8 passes through the raised rubber ring 6 and is inserted into the positioning hole 11. With the above structure, it is easy to connect the sealing rubber ring 4 and the positioning block 2, which is convenient for the sealing rubber ring 4 to be fitted onto or removed from the metal ring 1. In specific operation, simply insert the raised rubber ring 6 into the inner groove 7 of the inner ring of the positioning block 2, and then insert the positioning shaft 8 into the raised rubber ring 6 through the mounting groove 9, so that the positioning block 2 and the sealing rubber ring 4 become one.

[0026] like Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, there are several positioning shafts 8 and positioning holes 11. A top plate 13 is provided in the mounting groove 9, and the top of each positioning shaft 8 is connected to the top plate 13. With the setting of several positioning shafts 8, positioning holes 11 and top plate 13, each positioning shaft 8 can be pulled out and separated from the raised rubber ring 6 by simply pulling the top plate 13, and it also ensures that the raised rubber ring 6 can be more firmly fixed in the inner ring of the positioning block 2.

[0027] like Figure 3 and Figure 7 As shown, elastic locking rods 10 are fixedly connected to both sides of the positioning block 2. Two locking grooves adapted to the elastic locking rods 10 are opened on the inner wall of the notch 3. With the setting of the elastic locking rods 10, the contact tightness between the positioning block 2 and the metal ring 1 can be strengthened, and the positioning block 2 can be prevented from detaching from the metal ring 1 at will.

[0028] like Figure 1 and Figure 2 As shown, several contact rings 5 ​​are fixedly connected to the upper and lower surfaces of the sealing ring 4. The contact rings 5 ​​enhance the contact sealing between the two shaft connectors and the sealing ring 4.

[0029] like Figure 5 and Figure 8 As shown, the inner ring of the sealing ring 4 is convex, which can squeeze between the two shaft connectors to ensure the sealing performance of the sealing ring 4 to the shaft connectors. The sealing ring 4 also has a buffer cavity 12 inside. The buffer cavity 12 can buffer the inner ring of the sealing ring 4, effectively reducing the severe wear of the sealing ring 4 and ensuring that the sealing ring 4 can be used stably on the metal ring 1.

[0030] The working principle and usage process of this utility model are as follows: When it is necessary to remove the sealing ring 4 from the metal ring 1, simply squeeze the two sides of the sealing ring 4 towards the center, and then pull the positioning block 2 outward to separate the sealing ring 4 from the metal ring 1. Then, flip open the sealing ring 4 above the positioning block 2 and pull out the positioning shaft 8 from the mounting groove 9 to separate the sealing ring 4 from the positioning block 2. Then, fix the new sealing ring 4 onto the positioning block 2 through the protruding ring 6 and the positioning shaft 8. When the sealing ring 4 is fitted onto the metal ring 1, simply squeeze the two sides of the sealing ring 4 towards the center, and then insert the sealing ring 4 directly into the center of the metal ring 1, so that the protruding ring 6 is inserted into the inner groove 7 to position the sealing ring 4. Finally, snap the positioning block 2 into the notch 3, thereby ensuring that the sealing ring 4 can be securely fitted onto the metal ring 1. The method of removing and installing the sealing ring 4 is more flexible and convenient.
