Description

Technical Field

[0001] This utility model belongs to the field of sealing ring technology, specifically relating to a combined pressure-resistant sealing ring. Background Technology

[0002] Combination seals refer to a type of seal where two or more seals are combined and installed together. This can greatly improve the performance of the seals and, due to the nature of their materials, they have high pressure resistance. They are commonly used in the combination of parts in industries such as automobiles.

[0003] Existing composite pressure-resistant sealing rings still have some defects. Most of them involve fitting one sealing ring onto the arc surface of another, using surface grooves to interlock and install the two components together for use on other metal parts. However, in actual use, it has been found that relying solely on surface grooves to connect the two sealing rings results in poor connection stability. Under strong external pressure, the rings may loosen due to significant deformation, making it difficult to ensure stable fit and affecting the sealing ring's performance and providing reliable protection for the components. Therefore, we propose a composite pressure-resistant sealing ring. Utility Model Content

[0004] The purpose of this invention is to provide a combined pressure-resistant sealing ring to solve the problem of poor stability after assembling two sealing rings as mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a combined pressure-resistant sealing ring, comprising a first sealing ring and a second sealing ring, wherein the second sealing ring is mounted on the top of the first sealing ring, and a protrusion is integrally formed on the bottom of the second sealing ring, and a groove is embedded on the surface of the first sealing ring, wherein the protrusion and the groove are slidably connected, a locking block is fixed on one side of the protrusion, and a buckle is slidably connected on the surface of the locking block, an opening is embedded on the surface of the first sealing ring, and a locking hole is provided on the side wall of the first sealing ring, wherein the buckle and the locking hole are fixed by engaging.

[0006] Preferably, the surface of the card block is provided with a storage groove, and a spring is installed inside the storage groove, with one end of the spring being fixedly connected to the buckle.

[0007] Preferably, the inner wall of the groove is provided with a limiting groove, the card block and the limiting groove are slidably connected, and a baffle is fixed inside the limiting groove.

[0008] Preferably, a limiting plate is fixed inside the limiting groove, and there are four sets of limiting plates and baffles in total.

[0009] Preferably, the bottom of the buckle is provided with an inclined surface, and there are four sets of buckles and buckle holes.

[0010] Compared with the prior art, the beneficial effects of this utility model are: 1. The two sealing rings are fixed by means of protrusions, grooves, locking blocks, buckles, openings and holes. Insert the locking block from the opening, rotate the second sealing ring to move the buckle until the buckle is engaged in the hole to complete the fixation. This effectively improves stability, reduces the risk of falling off, and makes it safer to use.

[0011] 2. The limiting groove can limit the movement of the card block, thereby effectively preventing the two sealing rings from falling off. The baffle can block the card block and control the rotation direction of the second sealing ring. The limiting plate can limit the movement of the card block, thereby ensuring that the buckle is accurately engaged in the card hole. Attached Figure Description

[0014] 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.

[0015] Please see Figure 1-4This utility model provides a technical solution: a combined pressure-resistant sealing ring, including a first sealing ring 1 and a second sealing ring 2. The second sealing ring 2 is installed on the top of the first sealing ring 1, and a protrusion 3 is integrally formed on the bottom of the second sealing ring 2. A groove 4 is embedded on the surface of the first sealing ring 1. The protrusion 3 and the groove 4 are slidably connected. A locking block 5 is fixed on one side of the protrusion 3. A buckle 6 is slidably connected on the surface of the locking block 5. An opening 7 is embedded on the surface of the first sealing ring 1. A locking hole 8 is provided on the side wall of the first sealing ring 1. The buckle 6 and the locking hole 8 are fixed by engaging. The two sealing rings are fixed by the protrusion 3, groove 4, locking block 5, buckle 6, opening 7 and locking hole 8. The locking block 5 is inserted from the opening 7, and the second sealing ring 2 is rotated to move the buckle 6 until the buckle 6 is engaged in the locking hole 8. This effectively improves stability, reduces the risk of falling off, and makes it safer to use.

[0016] Specifically, the surface of the card block 5 is embedded with a storage groove 9, and a spring 10 is installed inside the storage groove 9. One end of the spring 10 is fixedly connected to the buckle 6. The storage groove 9 and the spring 10 are used to control the buckle 6.

[0017] Specifically, the inner wall of the groove 4 is provided with a limiting groove 11, the locking block 5 is slidably connected to the limiting groove 11, and a baffle 12 is fixed inside the limiting groove 11. The limiting groove 11 can limit the locking block 5, thereby effectively preventing the two sealing rings from falling off. The baffle 12 can block the locking block 5 and control the rotation direction of the second sealing ring 2.

[0018] Specifically, a limiting plate 13 is fixed inside the limiting groove 11. There are four sets of limiting plates 13 and baffles 12. The limiting plates 13 can limit the card block 5, thereby ensuring that the buckle 6 is accurately engaged in the card hole 8.

[0019] Specifically, the bottom of the buckle 6 is provided with an inclined surface, and there are four sets of buckles 6 and buckle holes 8. Because the bottom of the buckle 6 is provided with an inclined surface, the buckle block 5 can be easily inserted into the opening 7.

[0020] In this embodiment, when assembling the two sealing rings, the locking block 5 is inserted into the opening 7. The buckle 6 retracts into the receiving groove 9 under the pressure of the inner wall of the opening 7, and at the same time, the spring 10 is compressed. At this time, the second sealing ring 2 is rotated, causing the locking block 5 to slide inside the limiting groove 11. When the locking block 5 slides to the position of the limiting plate 13, the buckle 6 will be locked into the locking hole 8 under the reaction force of the spring 10, thus completing the fixation of the two sealing rings and reducing the risk of them falling off. The limiting groove 11 can limit the locking block 5, thereby effectively preventing the two sealing rings from falling off. The baffle 12 can block the locking block 5 and control the rotation direction of the second sealing ring 2. The limiting plate 13 can limit the locking block 5, thereby ensuring that the buckle 6 is accurately locked into the locking hole 8.

[0021] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
