Description

Technical Field

[0001] This utility model relates to the field of nylon tube technology, specifically a high-strength automotive vacuum nylon tube. Background Technology

[0002] Nylon tubing is a type of pipe made of nylon material, commonly used in various industrial and engineering applications. Nylon is a synthetic polymer, and due to its excellent abrasion resistance, chemical resistance, and elasticity, nylon tubing is widely used in automotive piping systems. Vacuum nylon tubing refers to tubing used in automotive vacuum systems, which needs to withstand high pressures.

[0003] In the prior art, Chinese Patent No. CN114986994B discloses a nylon tube and its preparation method, belonging to the fields of plastic modification, product processing, and wire harness protection. The nylon tube protected by this invention includes an outer low-temperature toughened modified nylon tube and a rigid modified inner liner nested within the outer low-temperature toughened modified nylon tube. The outer low-temperature toughened modified nylon tube comprises the following raw materials by mass percentage: 75%–94% of a first nylon, 5%–15% of a toughening agent, 0.5%–5% of a water-absorbing agent, and 0.5%–5% of an antifreeze agent. The rigid modified inner liner provides greater rigidity to the nylon tube, while the outer low-temperature toughened modified nylon tube improves the low-temperature impact toughness of the nylon tube. Furthermore, the toughening agent, water-absorbing agent, and antifreeze agent, along with a steaming and water-absorbing process, jointly improve the low-temperature impact toughness of the first nylon, achieving a balance between flexibility and rigidity in the double-layer rigid-flexible structure.

[0004] Based on the above information, it can be seen that the existing technology generally aims to enhance the strength of nylon tubes by improving the formulation of nylon materials. However, in actual use, the strength is always limited due to the inherent limitations of the material itself, and it may be insufficient when facing high-pressure situations such as automotive vacuum systems. Utility Model Content

[0005] The purpose of this invention is to provide a high-strength automotive vacuum nylon tube to solve the problem of limited overall strength mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-strength automotive vacuum nylon tube, comprising a nylon tube body for a vehicle vacuum system:

[0007] The inner wall of the nylon tube body is provided with reinforcing ribs arranged in parallel with it, and explosion-proof rings are installed on the front and rear ends of the nylon tube body and nested therewith. A disassembly and installation mechanism is provided between the explosion-proof rings and the nylon tube body.

[0008] The nylon tube body includes a first substrate, a second substrate, an inner braided layer, an outer braided layer, and an anti-corrosion coating, and the outer braided layer, the second substrate, the inner braided layer, the first substrate, and the anti-corrosion coating are arranged in order from the outside to the inside.

[0009] Preferably, both the first substrate and the second substrate are made of nylon, and the anti-corrosion coating is made of epoxy resin.

[0010] Preferably, the inner braided layer is located between the first substrate and the second substrate, and the inner braided layer is configured as a cross-braided metal wire structure.

[0011] Preferably, the outer braided layer is located on the outermost side of the nylon tube body, and the outer braided layer is configured as a polyester fiber structure with horizontal and vertical braids.

[0012] Preferably, the inner wall of the nylon tube body is fixedly provided with uniformly distributed auxiliary strips, and the auxiliary strips are arranged in a spiral inclined manner.

[0013] Preferably, the disassembly and installation mechanism includes a mounting protrusion fixedly installed on the inner wall of the explosion-proof ring, and the mounting protrusion and the mounting groove formed on the outer surface of the nylon tube body form a sliding disassembly and installation structure, and the mounting groove is located at the top of the front and rear sides of the nylon tube body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: This high-strength automotive vacuum nylon tube adopts a novel structural design, the specific details of which are as follows:

[0015] 1. The main body of the nylon tube is divided into five parts: outer braided layer, second base material, inner braided layer, first base material and anti-corrosion coating. The inner braided layer, made of metal wire, is wrapped between the first base material and the second base material. The tension of the inner braided layer increases the overall strength of the pipe. Combined with the outermost polyester fiber outer braided layer, the overall strength of the pipe is further increased, so that the pipe can adapt to the high-pressure vacuum system in the vehicle.

[0016] Furthermore, reinforcing ribs and auxiliary strips are provided on the inner wall of the nylon tube body. The reinforcing ribs are used to further improve the overall strength, and the spiral structure of the auxiliary strips can give the medium (gas or liquid) a certain rotational force when it flows in the pipe, thereby making the flow smoother.

[0017] 2. Explosion-proof rings are installed at both ends of the nylon pipe body. The explosion-proof rings protect the pipe from excessive pressure at the joint and prevent it from breaking. The explosion-proof rings are installed and removed through the mounting protrusions on their inner walls and the mounting grooves on the outer surface of the nylon pipe body. This allows for the selection of an appropriate number of explosion-proof rings to be installed according to the actual situation. Attached Figure Description

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1: Please refer to Figure 1 and Figure 3 In order to enhance the overall strength of the pipeline, this embodiment provides the following technical solution, specifically disclosing: a nylon tube body 1 for a vehicle vacuum system. The nylon tube body 1 includes a first substrate 101, a second substrate 102, an inner braided layer 103, an outer braided layer 104, and an anti-corrosion coating 105. The outer braided layer 104, the second substrate 102, the inner braided layer 103, the first substrate 101, and the anti-corrosion coating 105 are arranged in an order from the outside to the inside. The first substrate 101 and the second substrate 102 are both made of nylon material, and the anti-corrosion coating 105 is made of epoxy resin material. The inner braided layer 103 is located between the first substrate 101 and the second substrate 102, and the inner braided layer 103 is a horizontally and vertically woven metal wire structure. The outer braided layer 104 is located on the outermost side of the nylon tube body 1, and the outer braided layer 104 is a horizontally and vertically woven polyester fiber structure.

[0026] The first substrate 101, the second substrate 102, the inner braided layer 103 and the outer braided layer 104 are combined together by extrusion or pressing to form the nylon tube body 1. Then, an anti-corrosion coating 105 is uniformly sprayed on the inner surface of the first substrate 101. When the pipe is in use, the tensile effect of the inner braided layer 103 and the outer braided layer 104 is used to improve the overall strength, thereby adapting to the high-pressure vacuum system of automobiles.

[0027] Example 2: Please refer to Figure 2 and Figure 4 In order to maintain the smooth flow of the medium inside the pipeline, this embodiment provides the following technical solution, which specifically discloses: the inner wall of the nylon tube body 1 is provided with reinforcing ribs 2 arranged in parallel with it, and explosion-proof rings 4 are installed on the front and rear ends of the nylon tube body 1 and nested therewith. The inner wall of the nylon tube body 1 is fixedly provided with evenly distributed auxiliary strips 3, and the auxiliary strips 3 are arranged in a spiral inclined manner.

[0028] During pipeline production, the inner wall of the first base material 101 is integrally formed with reinforcing ribs 2 and auxiliary strips 3. The reinforcing ribs 2 are used to increase the overall bending resistance of the nylon pipe body 1. At the same time, the medium flows inside the nylon pipe body 1 and rotates under the action of the auxiliary strips 3 (rotation will have better fluidity), thereby ensuring the smooth flow of the medium.

[0029] Example 3: Please refer to Figure 5 In order to improve the strength of the pipe joint, this embodiment provides the following technical solution, which specifically discloses that: a disassembly and installation mechanism is provided between the explosion-proof ring 4 and the nylon pipe body 1. The disassembly and installation mechanism includes an installation protrusion 5 fixedly installed on the inner wall of the explosion-proof ring 4, and the installation protrusion 5 and the installation groove 6 opened on the outer surface of the nylon pipe body 1 form a sliding disassembly and installation structure, and the installation groove 6 is located at the top of the front and rear sides of the nylon pipe body 1.

[0030] Before connecting the pipeline to the automotive vacuum system, select an appropriate number of explosion-proof rings 4 according to actual needs. Align the mounting protrusions 5 on the inner wall of the explosion-proof rings 4 with the mounting grooves 6 opened on the outer surface of the nylon tube body 1. Then slide the mounting protrusions 5 into the mounting grooves 6 to install the explosion-proof rings 4. Finally, the explosion-proof rings 4 are used to prevent the nylon tube body 1 from cracking at the docking position.
