Abstract
Description
Technical Field
[0001] This utility model relates to the field of silicon core tube technology, and in particular to a high-rigidity, high-toughness, and anti-aging HDPE silicon core tube connector. Background Technology
[0002] Silicon core pipe is a new type of composite pipe with an inner wall containing a silica-based solid lubricant. It offers good sealing performance, resistance to chemical corrosion, and low engineering costs. HDPE silicon core pipe, also known as silicon pipe, is a type of composite pipe with an inner wall containing a silica-based solid lubricant. Its main raw material is high-density polyethylene, and the core layer is made of silica, a solid lubricant with the lowest coefficient of friction. It is widely used in fiber optic cable communication network systems for highways, railways, etc. HDPE silicon core pipes are typically connected using HDPE silicon core pipe joints.
[0003] During the laying of HDPE silicon core pipes, unpredictable forces often cause difficulties, and workers dare not pull them too hard, as this can easily damage the HDPE silicon core pipe joints. Furthermore, when encountering severe cold weather, the HDPE silicon core pipe joints are prone to freezing cracks and aging due to the lack of insulation, thus affecting the service life of the HDPE silicon core pipe joints. Utility Model Content
[0004] The technical problem to be solved by this utility model is to provide a high-rigidity, high-toughness, and anti-aging HDPE silicon core pipe joint, in order to solve the problems mentioned in the background art, such as the joint being easily damaged by stretching, freezing cracking, and aging.
[0005] To solve the above-mentioned technical problems, the technical solution of this utility model is as follows:
[0006] A high-rigidity, high-toughness, and anti-aging HDPE silicon core tube connector includes a connector body. The connector body includes a plug connection part and a silicon core tube connection part integrally connected to the plug connection part. The plug connection part has an internal thread on its inner side. Both the plug connection part and the silicon core tube connection part have an anti-aging mechanism on their inner sides. The anti-aging mechanism includes a heat insulation part and a heat insulation layer inside. The silicon core tube connection part also has an anti-tensile mechanism on its inner side. The anti-tensile mechanism is composed of a steel wire ring, a steel wire mesh, and a filler part.
[0007] Preferably, the insulation part includes an insulation layer, support columns and an adhesive layer, the support columns are equidistantly distributed in the insulation layer, and the adhesive layer is connected to the insulation layer and the heat insulation layer respectively.
[0008] Preferably, the interior of the filling portion includes a rubber layer and a reinforcing filling layer, the rubber layer covering the outside of the steel wire ring, and the reinforcing filling layer filling the space between the rubber layer and the steel wire ring.
[0009] Preferably, the wire mesh covers the outside of the rubber layer, and the surface of the wire mesh is fixedly connected to the heat insulation layer.
[0010] Preferably, the insulation layer is made of polyurethane insulation material.
[0011] Preferably, the heat insulation layer is made of glass fiber material.
[0012] By adopting the above technical solution, the high-rigidity, high-toughness, and anti-aging HDPE silicon core pipe joint provided by this utility model has the following beneficial effects:
[0013] 1. By incorporating an anti-tensile mechanism, the overall strength of the plug connection and the silicon core tube connection is enhanced, increasing the tensile load resistance of the HDPE silicon core tube joint. The wire mesh is a ring-shaped mesh formed by the interlacing of horizontal and vertical steel wires. Under the action of the wire mesh, it can not only support the silicon core tube connection but also effectively improve the tensile strength of the silicon core tube connection, thus realizing the tensile load resistance function of the HDPE silicon core tube joint. This avoids damage to the HDPE silicon core tube joint due to tension during use, improves the overall rigidity and toughness, and facilitates subsequent construction.
[0014] 2. By incorporating an anti-aging mechanism, the HDPE silicon core pipe joint can be insulated and protected against freezing under the action of the insulation part and the heat insulation layer, avoiding freezing cracks and aging. This achieves the insulation and anti-freezing function of the HDPE silicon core pipe joint, thereby extending its service life. Attached Figure Description

Detailed Implementation
[0019] The specific embodiments of this utility model will be further described below with reference to the accompanying drawings. It should be noted that these descriptions are for the purpose of aiding understanding of this utility model, but do not constitute a limitation thereof. Furthermore, the technical features involved in the various embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0021] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this utility model, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.
[0022] like Figure 1-3 As shown, the high-rigidity, high-toughness, and anti-aging HDPE silicon core tube connector includes a connector body 1. The connector body 1 includes a plug connection part 2 and a silicon core tube connection part 3 integrally connected to the plug connection part 2. The plug connection part 2 has an internal thread 4 on its inner side. Both the plug connection part 2 and the silicon core tube connection part 3 have an anti-aging mechanism 5 on their inner sides. The anti-aging mechanism 5 contains a heat insulation part 6 and a heat insulation layer 7. The silicon core tube connection part 3 also has a tensile strength mechanism 8 on its inner side. The tensile strength mechanism 8 consists of a steel wire ring 9, a steel wire mesh 10, and a filling part 11. It is understood that the heat insulation layer 7 is made of glass fiber material.
[0023] Specifically, the insulation section 6 includes an insulation layer 12, support columns 13, and an adhesive layer 14. The support columns 13 are equidistantly distributed within the insulation layer 12, and the adhesive layer 14 is connected to both the insulation layer 12 and the heat insulation layer 7. It is understood that the insulation layer 12 is made of polyurethane insulation material.
[0024] Specifically, the interior of the filling part 11 includes a rubber layer 15 and a reinforcing filling layer 16. The rubber layer 15 covers the outside of the steel wire ring 9, the reinforcing filling layer 16 fills the space between the rubber layer 15 and the steel wire ring 9, the steel wire mesh 10 covers the outside of the rubber layer 15, and the surface of the steel wire mesh 10 is fixedly connected to the heat insulation layer 7.
[0025] Understandably, this utility model has a reasonable design and unique structure. By setting up an anti-tensile mechanism 8, the overall strength of the plug connection part 2 and the silicon core tube connection part 3 can be enhanced, and the tensile load of the HDPE silicon core tube joint can be improved. The wire mesh 10 is a ring-shaped mesh formed by the cross-shaped horizontal and vertical wires. Under the action of the wire mesh 10, it can not only support the silicon core tube connection part 3, but also effectively improve the tensile strength of the silicon core tube connection part 3, realizing the tensile load function of the HDPE silicon core tube joint. This avoids the phenomenon of damage caused by tension during the use of the HDPE silicon core tube joint, improves the overall rigidity and toughness, and facilitates subsequent construction. By setting up an anti-aging mechanism 5, under the action of the insulation part 6 and the heat insulation layer 7, the HDPE silicon core tube joint can be insulated and protected against freezing, avoiding freezing cracks and aging. This realizes the heat insulation and anti-freezing function of the HDPE silicon core tube joint, thereby extending the service life of the HDPE silicon core tube joint.
