Description

Technical Field

[0001] The utility model belongs to the technical field of sealing rings, and in particular relates to a spring frame sealing ring. Background Art

[0002] The spring skeleton seal is composed of a polymer sealing shell and a corrosion-resistant stainless steel metal spring. The seal is installed in the groove. The spring is compressed to form an outward tension, which causes the sealing lip to fit tightly against the sealing groove. Since the spring permanently provides elastic force to the sealing lip, it can compensate for the wear of the sealing shell and the eccentricity of the mating parts, thereby forming a seal from vacuum to low pressure.

[0003] The spring frame seals currently available on the market have the following problems in actual use:

[0004] 1. In actual use, the traditional spring frame seal ring has no disassembly effect because the spring frame is installed inside the seal ring and limited inside the seal ring. When the spring frame seal ring is under pressure and compressed inward, the spring frame may be deformed. At this time, the entire spring frame seal ring can only be replaced, which is costly to use.

[0005] 2. Most spring skeleton seals are usually packed in plastic bags during transportation or storage. The plastic bags are relatively soft. When the spring skeleton seals are subjected to pressure, they may deform and provide poor protection during use. Utility Model Content

[0006] The utility model aims to provide a spring frame sealing ring to solve the technical problems raised in the background technology.

[0028] In order to better understand the purpose, structure and function of the utility model, a spring skeleton sealing ring of the utility model is further described in detail below in conjunction with the accompanying drawings.

[0029] like Figure 1-5 As shown, a spring skeleton sealing ring of the utility model comprises a sealing ring body 3, a groove 8 is provided at the top of the sealing ring body 3, a spring body 4 is clamped inside the sealing ring body 3, an internal threaded hole 9 is provided inside the groove 8, a second retaining ring 6 is provided inside the groove 8, by installing the second retaining ring 6, the spring body 4 can be limited inside the sealing ring body 3 by using the second retaining ring 6, so that the spring body 4 will not be separated from the outside of the sealing ring body 3, which is very convenient to use, a bolt 7 is installed inside the second retaining ring 6, one end of the bolt 7 is embedded in the internal threaded hole 9, and the bottom of the second retaining ring 6 is attached to the top of the spring body 4, by installing the bolt 7 and providing the internal threaded hole 9, the bolt 7 and the internal threaded hole 9 can provide the second retaining ring 6 with installation and disassembly effects, and then the spring body 4 can be taken out, which is very convenient to use.

[0030] A box body 2 is provided outside the sealing ring body 3, and a blocking column 13 is fixedly connected inside the box body 2. The inner wall of the sealing ring body 3 fits the surface of the blocking column 13. A box cover 1 is installed on the top of the box body 2, and an externally threaded rod 14 is installed on the top of the box cover 1. One end of the externally threaded rod 14 is embedded in the blocking column 13, and a blocking piece 15 is welded to the other end of the externally threaded rod 14. The bottom of the blocking piece 15 fits the top of the box cover 1. By installing the box body 2 and the box cover 1, the box cover 1 and the box body 2 are used to protect the spring skeleton sealing ring, so that the pressure will not be transmitted to the spring skeleton sealing ring, and the protection is strong when used.

[0031] The top of the sealing ring body 3 is fixedly connected to the first retaining ring 5, and the bottom of the first retaining ring 5 is fitted to the spring body 4. The spring body 4 is in a ring-shaped distribution form. By installing the first retaining ring 5, the first retaining ring 5 is used to limit the spring body 4 to ensure the stability of the spring body 4. The stability is relatively strong when in use.

[0032] A card slot 10 is provided at the top of the box body 2, a card slot 10 is internally engaged with a card ring 12, a sealing ring 11 is bonded to the top of the card ring 12, and the top of the sealing ring 11 is attached to the bottom of the box cover 1. By installing the sealing ring 11, the sealing ring 11 is used to seal the gap between the box cover 1 and the box body 2, so that external dust will not enter through the gap between the box body 2 and the box cover 1, and the sealing performance is strong during use.

[0033] A ball head 16 is welded on the top of the baffle 15, and a torsion plate 17 is welded on the surface of the ball head 16. The torsion plate 17 is distributed in a ring shape. By installing the torsion plate 17, when the external threaded rod 14 needs to be rotated, the torsion plate 17 can be used as a force point, which is more convenient and labor-saving when rotating the external threaded rod 14.

[0034] The bolts 7 are distributed in a ring shape, and the internal threaded holes 9 are distributed in a ring shape. Through the distribution pattern of the bolts 7, when the first retaining ring 5 is fixed by the bolts 7, a stable fixing effect can be provided for the first fixing ring, and the stability is relatively strong during use.

[0035] The working principle of the spring skeleton sealing ring: when using the spring skeleton sealing ring, the spring body 4 should be placed inside the sealing ring body 3 first, and then the second retaining ring 6 should be installed inside the groove 8. When installing the second retaining ring 6, the second retaining ring 6 should be directly placed inside the groove 8, and the bolt 7 should be used to penetrate the second retaining ring 6 until one end of the bolt 7 is embedded in the internal threaded hole 9. Then the spring skeleton sealing ring can be used. During use, when the spring body 4 inside it is deformed due to pressure, the bolt 7 can be removed and the second retaining ring 6 can be taken out. At this time, the deformed spring body 4 can be taken out and replaced, and then installed again after replacement. The second retaining ring 6 fixes the spring body 4 inside the sealing ring body 3, and there is no need to replace the spring skeleton sealing ring as a whole, which reduces costs during use. When transporting or storing the spring skeleton sealing ring, the spring skeleton sealing ring can be placed inside the box body 2, and the box cover 1 is installed on the top of the box body 2. At the same time, the external threaded rod 14 is used to penetrate the box cover 1 and the retaining column 13 until the bottom of the retaining plate 15 is attached to the top of the box cover 1 to fix the box cover 1. At this time, when the spring skeleton sealing ring is hit, the box cover 1 and the box body 2 can be used to protect the spring skeleton sealing ring so that the pressure will not be transmitted to the spring skeleton sealing ring, and the protection is strong during use.
