Description

Technical Field

[0001] This utility model relates to the field of hose technology, specifically a composite high-pressure resistant hose. Background Technology

[0002] Rubber hoses are now used in many areas of daily life and production. They are commonly used as water pipes, gas pipes, ventilation pipes, oil pipes, and high-pressure pipes, among others. Rubber hoses possess properties such as physiological inertness, UV resistance, ozone resistance, high and low temperature resistance, high transparency, strong resilience, permanent compression resistance, oil resistance, impact resistance, acid and alkali resistance, wear resistance, flame retardancy, voltage resistance, and electrical conductivity.

[0003] Publication number CN221121375U discloses a high-pressure resistant rubber oil hose, including a rubber hose body with a metal braided mesh inside. Both ends of the hose body have cylindrical connectors, one end of which is threaded to a locking cylinder. The connector and locking cylinder are respectively clamped on the inner and outer sides of the hose body end. Two limiting rings are slidably fitted on the hose body. In this invention, the metal braided mesh inside the hose body wall enhances the high-pressure resistance of the hose body. Simultaneously, the connecting plate, connecting rings, and locking cylinder form a fixed, immovable unit, thus achieving the effect of bending and shaping the hose body after bending.

[0004] The hoses in the above-mentioned comparative documents have generally poor stability, cumbersome and time-consuming installation at the connection points, and poor sealing performance. They also lack a quick-locking structure. Therefore, a composite high-pressure resistant hose was designed here to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a composite high-pressure resistant hose in order to solve the problems of traditional hoses, such as poor stability, cumbersome and time-consuming installation of hose connections, poor sealing performance, and lack of a quick locking structure.

[0006] To achieve the above objectives, the technical solution of this utility model is as follows: a composite high-pressure resistant hose, comprising hoses connected end-to-end, with an annular recessed groove at the connection point of the hoses, and interlocking arc-shaped clamps installed at the connection point of the hoses. A convex ring that mates with the recessed groove is provided on the inner wall of the arc-shaped clamp, an external threaded portion is provided on the outer side of the arc-shaped clamp, and an internal threaded portion is provided on the inner side of the arc-shaped clamp; an external threaded ring is threaded onto the external threaded portion, and an internal threaded ring is threaded onto the internal threaded portion, the internal threaded ring locking the arc-shaped clamps on both sides; the hose comprises inner and outer rubber layers, with a skeleton layer and a composite layer disposed between the rubber layers, the skeleton layer located outside the composite layer.

[0007] As a further improvement of this utility model: locking bosses are provided on both sides of the arc-shaped hoop, and bolts are threaded onto the locking bosses.

[0008] As a further improvement of this utility model, multiple sets of first protrusions are provided on the outer wall of the outer spiral ring.

[0009] As a further improvement of this utility model, multiple sets of second protrusions are provided on the outer wall of the inner thread ring.

[0010] As a further improvement of this utility model, the skeleton layer is woven from metal fiber filaments.

[0011] As a further improvement of this utility model, the composite layer is made of nylon fiber and polyester resin.

[0012] As a further improvement of this utility model, the first and second convex plates are provided with anti-slip patterns.

[0013] This utility model provides a composite high-pressure resistant hose through improvements, which has the following improvements and advantages compared with the prior art:

[0014] This invention utilizes multiple sets of arc-shaped clamps on both sides to quickly connect and fix the hoses. The combination of external and internal threaded rings provides multiple locking mechanisms for the arc-shaped clamps, further improving airtightness and preventing oil leakage. The inclusion of a skeleton layer and a rubber layer ensures the hose's flexibility, allowing it to bend according to actual needs. Simultaneously, metal fiber filaments further protect the hose from cracking due to excessive internal pressure, thus improving overall strength. The simple structure and ease of maintenance further enhance the practicality and stability of this composite high-pressure resistant hose. Attached Figure Description

[0022] This utility model provides an improved composite high-pressure resistant hose, such as... Figures 1-3 As shown, a composite high-pressure resistant hose includes hoses 1 connected end to end. An annular groove 2 is provided at the connection point of the hoses 1. Interlocking arc-shaped clamps 3 are installed at the connection point of the hoses 1. A convex ring 4 that mates with the groove 2 is provided on the inner wall of the arc-shaped clamp 3. An external threaded portion 5 is provided on the outer side of the arc-shaped clamp 3, and an internal threaded portion 6 is provided on the inner side of the arc-shaped clamp 3. An external threaded ring 9 is threaded onto the external threaded portion 5, and an internal threaded ring 10 is threaded onto the internal threaded portion 6. The internal threaded ring 10 locks the arc-shaped clamps 3 on both sides. The hose 1 includes inner and outer rubber layers 13, with a skeleton layer 14 and a composite layer 15 disposed between the rubber layers 13. The skeleton layer 14 is located outside the composite layer 15.

[0023] This invention utilizes multiple sets of arc-shaped clamps 3 on both sides to quickly connect and fix the hoses 1 on both sides. The arc-shaped clamps 3 can be locked in multiple ways with the cooperation of the outer screw ring 9 and the inner screw ring 10, further improving the airtightness and preventing oil leakage. The skeleton layer 14 and the rubber layer 13 ensure the flexibility of the hose 1, allowing it to bend according to actual needs. Simultaneously, the metal fiber filaments further protect the hose 1 from cracking due to excessive internal pressure, thus improving overall strength. This simple structure is easy to maintain, further enhancing the practicality and stability of this composite high-pressure resistant hose.

[0024] See appendix Figure 1 - Appendix Figure 2 The arc-shaped hoop 3 has locking bosses 7 on both sides, and bolts 8 are threaded on the locking bosses 7.

[0025] In this embodiment: a bolt 8 is designed to fix the arc-shaped hoop 3 and to allow the convex ring 4 to fall into the recessed groove 2.

[0026] See appendix Figure 1 Multiple sets of first protrusions 11 are provided on the outer wall of the outer thread ring 9, and multiple sets of second protrusions 12 are provided on the outer wall of the inner thread ring 10.

[0027] In this embodiment: when connecting the hose 1, firstly, the outer threaded ring 9 is fitted onto the hoses 1 on both sides, and then the two sets of arc-shaped clamps 3 are fixed onto the hoses 1 on the same side. Finally, the outer threaded ring 9 fitted onto the hose 1 is tightened onto the external threaded portion 5, and the internal threaded portions 6 on both sides are locked by the inner threaded ring 10.

[0028] See appendix Figure 3 The skeleton layer 14 is woven from metal fiber filaments, and the composite layer 15 is made of nylon fiber and polyester resin.

[0029] In this embodiment, the metal fiber filaments further protect the hose 1 from cracking due to excessive internal pressure, thereby improving its overall strength. The skeleton layer 14 and the adhesive layer 13 ensure the flexibility of the hose 1, allowing it to be bent according to actual needs.

[0030] See appendix Figure 1 The first convex plate 11 and the second convex plate 12 are provided with anti-slip patterns.

[0031] In this embodiment: when the first convex plate 11 and the second convex plate 12 are rotated, in order to increase the friction and avoid accidental slippage, an anti-slip pattern (not shown) is designed.
