Description

Technical Field

[0001] This utility model relates to the field of rubber sealing joint technology, specifically to an anti-flexibility rubber sealing component. Background Technology

[0002] Flexible rubber joints (also known as vibration dampers or flexible joints) are pipe connection devices made of fabric-reinforced rubber and metal flanges through a vulcanization process. They are mainly used in engineering fields such as chemical, construction, and water supply and drainage. The products achieve vibration isolation and noise reduction through elastic deformation, and compensate for axial expansion and displacement of pipelines caused by temperature changes, vibration or settlement.

[0003] Existing rubber sealing joints, such as the rubber joint disclosed in publication number CN221237357U, have the advantage of significantly reducing vibration and noise when external liquid flows into or out of such a rubber joint. However, the part of the rubber joint that is subjected to periodic bending or deformation is not easy to thicken, and the inner and outer ends are not easy to effectively reinforce, which makes its flexural resistance poor. Therefore, we propose a flexural resistance rubber sealing component. Utility Model Content

[0004] This utility model aims to solve one of the technical problems existing in the prior art or related technologies.

[0005] Therefore, the technical solution adopted by this utility model is as follows:

[0006] A flexural rubber sealing assembly includes: a sealing joint and a reinforcing assembly; the sealing joint includes a rubber sealing sleeve and flanges that are movably installed at both ends of the rubber sealing sleeve; the reinforcing assembly includes a thickened portion provided in the middle of the rubber sealing sleeve, a steel wire skeleton fixedly provided inside the rubber sealing sleeve, multiple sets of inner rubber reinforcing ribs arranged and fixedly provided at the inner end of the thickened portion, multiple sets of outer rubber reinforcing ribs arranged and fixedly provided at the inner and outer ends of the thickened portion, and a protective sleeve fixedly installed at the inner end of the flange.

[0007] Preferably, each of the inner rubber reinforcing ribs is also fixedly provided with an inner reinforcing steel wire.

[0008] Preferably, each of the outer rubber reinforcing ribs is also fixedly provided with an outer reinforcing steel wire.

[0009] Preferably, both ends of the rubber sealing sleeve are provided with a bayonet, and one end of the flange is fixedly provided with a convex ring, and the convex ring and the bayonet are matched.

[0010] Preferably, both ends of the rubber sealing sleeve are provided with round holes, and one end of the flange is provided with fixed posts, and the fixed posts and round holes are matched.

[0011] Preferably, each of the protective sleeves has a movably installed rubber sealing sleeve at its outer end.

[0012] By adopting the above technical solution, the beneficial effects achieved by this utility model are as follows:

[0013] 1. In this utility model, the thickened part and steel wire skeleton provided in the middle and inside of the rubber sealing sleeve, as well as the inner rubber reinforcing ribs, outer rubber reinforcing ribs, inner reinforcing steel wires and outer reinforcing steel wires arranged and installed at the inner and outer ends of the thickened part, can significantly strengthen the middle part and the inner and outer sides of the middle part of the rubber sealing sleeve to resist periodic bending or deformation during use, thereby significantly improving the flexural resistance of the rubber sealing sleeve during use. The protective sleeves installed at both ends of the rubber sealing sleeve at the inner end of the flange can protect the two ends of the rubber sealing sleeve, so that the middle part of the rubber sealing sleeve mainly bears the periodic bending or deformation, thereby reducing the damage to the two ends of the rubber sealing sleeve.

[0014] 2. In this utility model, the convex ring at the upper end of the flange and the fixing post can also be engaged in the snap-fit ​​and round hole at both ends of the rubber sealing sleeve to improve the connection stability between the flange and the rubber sealing sleeve and prevent the rubber sealing sleeve from detaching during use.

[0024] Example 1:

[0025] Combination Figure 1-4 As shown, this utility model provides an anti-flexibility rubber sealing assembly, comprising: a sealing joint 100 and a reinforcing assembly 200; the sealing joint 100 includes a rubber sealing sleeve 101 and a flange 102 movably mounted at both ends of the rubber sealing sleeve 101; the reinforcing assembly 200 includes a thickened portion 201 provided in the middle of the rubber sealing sleeve 101, a steel wire skeleton 202 fixedly provided inside the rubber sealing sleeve 101, multiple sets of inner rubber reinforcing ribs 203 arranged and fixedly provided at the inner end of the thickened portion 201, multiple sets of outer rubber reinforcing ribs 204 arranged and fixedly provided at the inner and outer ends of the thickened portion 201, and a protective anti-flexibility rubber seal fixedly mounted at the inner end of the flange 102. The protective sleeve 205 has an inner reinforcing steel wire 206 fixedly installed inside the inner rubber reinforcing rib 203, and an outer reinforcing steel wire 207 fixedly installed inside the outer rubber reinforcing rib 204. The rubber sealing sleeve 101 has a bayonet 208 at both ends. The flange 102 has a convex ring 209 fixedly installed at one end, and the convex ring 209 matches the bayonet 208. The rubber sealing sleeve 101 has round holes 210 arranged at both ends. The flange 102 has a fixing post 211 arranged and fixedly installed at one end, and the fixing post 211 matches the round hole 210. The outer end of the rubber sealing sleeve 101 is movably installed on the protective sleeve 205.

[0026] Specifically, the flexible rubber joint is a pipe connection device made of fabric-reinforced rubber and metal flanges through a vulcanization process. The product achieves vibration isolation and noise reduction through elastic deformation, and compensates for axial expansion and displacement caused by temperature changes, vibration, or settlement of the pipeline. The thickened portion 201 and steel wire skeleton 202 in the middle and inside of the rubber sealing sleeve 101 of this sealing joint 100, along with the inner rubber reinforcing ribs 203, outer rubber reinforcing ribs 204, inner reinforcing steel wire 206, and outer reinforcing steel wire 207 arranged at the inner and outer ends of the thickened portion 201, significantly reinforce the middle and both inner and outer sides of the rubber sealing sleeve 101 to resist periodic stresses during use. The protective sleeves 205 installed at both ends of the rubber sealing sleeve 101 inside the flange 102 can protect the two ends of the rubber sealing sleeve 101, so that the middle part of the rubber sealing sleeve 101 mainly bears the periodic bending or deformation, thereby reducing the damage to the two ends of the rubber sealing sleeve 101. At the same time, the convex ring 209 and the fixing post 211 at the upper end of the flange 102 can also be engaged in the bayonet 208 and the round hole 210 at both ends of the rubber sealing sleeve 101 to improve the connection stability between the flange 102 and the rubber sealing sleeve 101 and prevent the rubber sealing sleeve 101 from detaching during use.

[0027] Working principle and usage process of this utility model:

[0028] After the sealing joint 100 is installed, the flanges 102 at both ends can be fitted onto both ends of the rubber sealing sleeve 101 through the inner protective sleeve 205, providing protection for both ends of the rubber sealing sleeve 101. The thickened part 201 in the middle of the rubber sealing sleeve 101, together with the steel wire skeleton 202 inside the rubber sealing sleeve 101, the inner rubber reinforcing ribs 203 and inner reinforcing steel wires 206 arranged at the inner end of the thickened part 201, and the outer rubber reinforcing ribs 204 and outer reinforcing steel wires 206 arranged at the outer end of the thickened part 201, can also provide protection for both ends of the rubber sealing sleeve 101. 07 can significantly enhance the strength, elasticity, and sealing performance of the middle part of the rubber sealing sleeve 101, thereby maintaining elastic recovery and sealing performance during periodic bending or deformation of the thickened part 201, and thus enhancing the flexural resistance of the rubber sealing sleeve 101 during use. The convex ring 209 and fixing post 211 provided on the flange 102 can also engage with the bayonet 208 and round hole 210 at both ends of the rubber sealing sleeve 101, thereby improving the stability of the connection between the rubber sealing sleeve 101 and the flange 102 during use.
