High pressure resistant PVC hose with reinforcing rib

Abstract

This utility model provides a high-pressure resistant PVC hose with reinforcing ribs, relating to the technical field of PVC hose structures. It addresses the problem that most hoses improve pressure resistance by increasing wall thickness, but the reinforcing structure is often poorly distributed, posing safety hazards. The hose includes an inner layer, a reinforcing sleeve, and a protective outer tube. The inner layer has a connecting groove on its outer side and a guide ring fixedly installed on its inner side. The reinforcing sleeve is fixedly fitted onto the outer side of the inner layer, and a bearing groove is formed on its inner side, with reinforcing ribs fixedly installed therein. The protective outer tube has an assembly groove on its inner side, with reinforcing ribs fixedly installed therein. The bending structure of the reinforcing ribs provides traction and tightening protection for the inner layer, reinforcing sleeve, and protective outer tube when they expand to a certain extent under pressure. The protective outer tube, in conjunction with the reinforcing ribs, further traction and tightens protection for the inner layer, reinforcing sleeve, and protective outer tube when they expand further.

Description

Technical Field

[0001] This utility model belongs to the technical field of PVC hose structure, and more specifically, it relates to a high-pressure resistant PVC hose with reinforcing ribs. Background Technology

[0002] PVC hoses are widely used in many fields such as industrial production and daily life because of their advantages such as low production cost, easy processing and molding, good flexibility and chemical stability. They are used in scenarios such as industrial water, oil transportation, sewage treatment, wind power generation, garden watering, and furniture cleaning.

[0003] Based on the above, some existing PVC hoses improve their pressure resistance by increasing the wall thickness. However, this not only increases the weight and cost of the hose, but also reduces its flexibility, making it inconvenient to install and use. In addition, the reinforcing structure is often poorly distributed, failing to fully enhance the hose's pressure resistance, resulting in uneven pressure resistance at different parts of the hose and posing safety hazards. Utility Model Content

[0004] To address the aforementioned technical problems, this utility model provides a high-pressure resistant PVC hose with reinforcing ribs. This addresses the issue that while some existing PVC hoses improve pressure resistance by increasing wall thickness, this not only increases the hose's weight and cost but also reduces its flexibility, making installation and use inconvenient. Furthermore, the reinforcing structure is often poorly distributed, failing to fully enhance the hose's pressure resistance and resulting in uneven pressure resistance at different points, posing safety hazards.

[0005] This utility model of a high-pressure resistant PVC hose with reinforcing ribs is achieved through the following specific technical means:

[0006] The core components of a reinforced high-pressure PVC hose include the following: an inner hose, a reinforcing sleeve, and a protective outer tube.

[0007] The inner flexible tube has a connecting groove on its outer side and a guide ring fixedly installed on its inner side; characterized in that the reinforcing sleeve is fixedly sleeved on the outer side of the inner flexible tube, the reinforcing sleeve has a connecting groove on its inner side and a bearing groove on its inner side, and a reinforcing rib is fixedly installed on its inner side; the protective outer tube is fixedly sleeved on the outer side of the reinforcing sleeve, the protective outer tube has an assembly groove on its inner side, and a reinforcing rib is fixedly installed on its inner side.

[0008] Furthermore, the outer side of the inner flexible tube is provided with a fitting groove, which is connected to the inner support groove.

[0009] Furthermore, a positioning support groove is provided on the outer side of the reinforcing sleeve, and the positioning support groove is connected to the assembly inner groove.

[0010] Furthermore, the outer side of the protective outer tube is also provided with anti-slip grooves.

[0011] The high-pressure resistant PVC hose with reinforcing ribs provided by this utility model has the following beneficial effects:

[0012] This utility model achieves the following optimization effects by incorporating an inner flexible tube, a reinforcing sleeve, and a protective outer tube:

[0013] First, a precise fit between the connecting outer groove and the connecting sleeve groove constructs a three-layer nested load-bearing system consisting of an inner flexible hose, a reinforcing sleeve, and a protective outer tube. This creates a stable mechanical transmission path between the components, effectively dispersing the pressure within the pipe. Second, the built-in guide inner ring precisely constrains the fluid delivery path, optimizing fluid dynamics to reduce local pressure concentration in the inner flexible hose and improve pressure resistance. Third, an innovatively designed bending reinforcing rib and reinforcement rib form a dual-stage elastic constraint mechanism. When the inner flexible hose expands to a critical point due to pressure, it automatically tightens the constraint, absorbing pressure energy through elastic deformation and preventing excessive expansion of the pipe. Fourth, the synergistic effect of the protective outer tube and reinforcement ribs maintains the overall structural rigidity while providing dynamic buffer protection for the internal components, ultimately achieving full-cycle pressure protection for the pipe system, significantly extending its service life and improving delivery safety.

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples.

[0026] Example 1: As Figures 1 to 4 As shown, the high-pressure resistant PVC hose with reinforcing ribs provided by this utility model includes an inner hose 1, a reinforcing sleeve 2, and a protective outer tube 3;

[0027] The inner flexible tube 1 has a connecting outer groove 101 on its outer side and a guide inner ring 103 fixedly installed on its inner side; characterized in that the reinforcing sleeve 2 is fixedly sleeved on the outer side of the inner flexible tube 1, the reinforcing sleeve 2 has a connecting sleeve groove 202 on its inner side and a bearing inner groove 203 on its inner side, and a reinforcing rib 204 is fixedly installed on its inner side; the protective outer tube 3 is fixedly sleeved on the outer side of the reinforcing sleeve 2, the protective outer tube 3 has an assembly inner groove 302 on its inner side, and a reinforcing rib 303 is fixedly installed on its inner side.

[0028] Example 2: Figures 2 to 4 As shown, the outer side of the inner flexible hose 1 is provided with a fitting groove 102, which is connected to the inner support groove 203; the outer side of the reinforcing sleeve 2 is provided with a positioning support groove 201, which is connected to the assembly inner groove 302; the outer side of the protective outer tube 3 is provided with an anti-slip groove 301; the inner flexible hose 1 used for transportation can be protected by the reinforcing sleeve 2 and the protective outer tube 3.

[0029] The specific usage and function of this embodiment are as follows: In use, the inner hose 1 is fixedly fitted onto the reinforcing sleeve 2 by connecting the outer groove 101 and cooperating with the connecting sleeve groove 202. The reinforcing sleeve 2 is fixedly fitted onto the protective outer tube 3 for support. The reinforcing sleeve 2 and the protective outer tube 3 together provide support and protection for the inner hose 1 during transport. The guide inner ring 103 guides and strengthens the transport of the inner hose 1, reducing the pressure on the inner hose 1. At the same time, the bending structure of the reinforcing rib 204 pulls and tightens the inner hose 1, reinforcing sleeve 2, and protective outer tube 3 when they expand to a certain extent under pressure. The protective outer tube 3, together with the reinforcing rib 303, further pulls and tightens the inner hose 1, reinforcing sleeve 2, and protective outer tube 3 during expansion, preventing damage to the inner hose 1, reinforcing sleeve 2, and protective outer tube 3 due to the pressure generated by the transported materials.
