Description

Technical Field

[0001] The utility model belongs to the field of sealing ring fixing devices, in particular to a steel skeleton rubber sealing ring fixing device. Background Art

[0002] The sealing rings used in the current steel skeleton structure need to be fixed in order to improve the sealing effect of the sealing ring. The traditional sealing method is to perform pressure sealing through the pressure between the rubber sealing ring and the pipe, which causes the sealing effect of the rubber sealing ring to decrease easily due to the deformation of the pipe and the use time, and the long-term sealing effect cannot be guaranteed. During the sealing process, thermal expansion and contraction will occur with the temperature change. The thermal expansion and contraction will make the material of the sealing ring reach the fatigue limit, thereby causing its recovery ability to deteriorate and resulting in sealing failure. Once the current single-layer seal fails, leakage will occur, and the service life of this single-layer seal will be relatively short. Utility Model Content

[0003] The utility model provides a steel frame rubber sealing ring fixing device with good sealing effect and convenient sealing, which is particularly suitable for fixing rubber sealing rings of steel frame structures. The technical problem to be solved is that the service life of the current single-layer sealing ring is relatively low.

[0004] The technical solution adopted by the utility model is:

[0005] A steel frame rubber sealing ring fixing device, comprising a fixing device, the fixing device comprising an outer set, an outer fixing part and an inner fixing part, the outer set is sleeved on the outside of the outer fixing part, the outer set is fixedly connected to the outer fixing part, the outer fixing part is sleeved on the outside of the inner fixing part, the outer fixing part is fixedly connected to the inner fixing part, a gap is left between the two ends of the outer fixing part and the two ends of the inner fixing part, and one outer set is arranged at each end of the outer fixing part;

[0006] The outer set consists of an upper set and a lower set, and the upper set is fixedly connected to the lower set.

[0007] Furthermore, an annular protrusion is arranged outwardly from the middle of the outer surface of the external fixing member, and an annular protrusion is arranged outwardly from the outer surface of one end of the outer sleeve member close to the protrusion in the middle of the outer surface of the external fixing member, and threaded through holes are arranged on the protrusions on the outer wall of the external fixing member and the outer wall of the outer sleeve member, and the external fixing member is fixedly connected to the outer sleeve members at both ends.

[0008] Furthermore, the outer walls of the upper and lower kits of the outer kit are both provided with connecting ears, the centers of the connecting ears are provided with threaded through holes, and the connecting ears of the upper and lower kits are the same in number and size.

[0009] Furthermore, an annular protrusion is arranged at the center of the inner wall of the external fixing member, a thread is arranged at the annular protrusion, and a thread is arranged on the outer wall of the external fixing member.

[0010] Furthermore, a raised annular boss is provided at the middle position of the outer side wall of the inner fixing member, and a thread is provided at the raised portion of the annular boss.

The outer set, the outer fixing and the inner fixing are used for connection, the outer fixing and the inner fixing are used for clamping and sealing, and the outer set is used for clamping and fixing, which overcomes the problem of leakage in the current single-layer seal once the sealing ring fails. As a result, after the inner sealing ring or the outer sealing ring fails, the other sealing ring can still play a sealing effect. By utilizing the different lifespans of the double-layer sealing ring, the sealing effect can still be guaranteed even if one of the sealing rings fails. At the same time, the cooperation of the double-layer sealing ring prolongs the sealing life.

[0016] 2. The use of inner and outer sealing rings to seal inside and outside the pipe overcomes the problems of unstable and low life of traditional single-layer sealing, thereby improving the sealing effect. The seals on both sides do not affect each other, and the failure of a single seal will not affect the other. BRIEF DESCRIPTION OF THE DRAWINGS
