Bundled tube sealing ring

Abstract

The invention discloses a bundled tube sealing ring. The bundled tube sealing ring comprises an elastic cushion, the elastic cushion comprises a first elastic ring and a second elastic ring, the periphery of one end of the first elastic ring and the periphery of one end of the second elastic ring are fixedly connected through a connecting part, a ring of pressurizing layer is fixedly arranged on the inner side of the second elastic ring, and multiple clamping parts are evenly and fixedly arranged on the inner side of a U-shaped groove formed by the first elastic ring, the second elastic ring and the connecting part; each clamping part comprises a first clamping protrusion, a second clamping protrusion and a buffer cushion, wherein the first clamping protrusions are fixedly adhered to the inner side of the first elastic ring, the buffer cushions are arranged to be in an elliptical shape, and the two long-axis ends of each buffer cushion are fixedly connected with the bottom end of the corresponding first clamping protrusion and the bottom end of the corresponding second clamping protrusion. According to the bundled tube sealing ring, the clamping parts are fixedly adhered to the inner side of the first elastic ring and the inner side of the second elastic ring, therefore, connection between the sealing ring and a bundled tube opening is tighter, and an internal sealing environment is guaranteed.

Description

technical field [0001] The invention relates to the technical field of bundle tube sealing rings, in particular to a bundle tube sealing ring. Background technique [0002] Bundle tubes are a collection of a certain number of microtubes, and multiple microtubes are wrapped by HDPE tubes with a thickness of 1-3 mm in the factory, that is, bundle tubes. It's a bit like the honeycomb tubes commonly used in our local telephone pipelines. It is composed of loose microtube units, a microtube bundle and an outer sheath. There is no adhesion between them, and there can be relative displacement. The advantage of bundled tubes is that the density of the tubes is high, and the most microtubes can be accommodated in the effective space. The disadvantage is that the flexibility is poor, the opening of the pipeline is inconvenient (referring to the thick-walled outer sheath), the inner microtube is difficult to diverge, and the impact resistance is also poor, because the microtube unit ...

AI Technical Summary

Problems solved by technology

[0004] 1. The connection between the gasket and the nozzle is not compact enough, and it is easy to slip

[0005] 2. On the inner side of the gasket, due to the large internal space of the tube body and the lack of a limiting structure for the internal material, the internal shaking of the cluster tube during use is relatively large, which is inconvenient to install
