Description

Technical Field

[0001] This utility model belongs to the field of hose technology, and in particular relates to a spiral hose. Background Technology

[0002] Spiral-reinforced flexible hoses on the market have smooth inner walls, but they are usually less flexible and the larger ribs result in a smaller inner diameter for the same outer diameter. A smaller inner diameter affects wind resistance. If the ribs are made thinner, the hose's resistance to negative pressure decreases, making it prone to flattening when bent. Steel wire hoses are more flexible and have smaller ribs, but their inner walls have spiral grooves and are not smooth, making them more prone to accumulating dust and dirt.

[0003] Furthermore, different scenarios have different requirements for the cross-sectional shape of the hose. The shape of the hose varies depending on the scenario, but currently most hoses are circular, with limited functionality and poor applicability.

[0004] One Chinese patent, CN2206396Y, describes a reinforced pressure-resistant plastic pipe. Its structure consists of circumferential reinforcing ribs on the outer wall of the plastic pipe, spaced axially around the pipe body. These ribs, made of metal or non-metal wires with significantly higher strength than the plastic pipe itself, are the main load-bearing components. The metal wires are covered with an anti-corrosion layer. The key feature is that the ribs are integrated with the pipe body via an adhesive layer, and the pipe body with the ribs is covered with a fiber-reinforced thermosetting plastic protective layer. However, this structure cannot be manufactured with different cross-sections to meet specific needs, resulting in poor applicability.

[0005] A fully plastic telescopic tube (CN219300494U) includes a plastic outer skin and plastic reinforcing bars. The plastic reinforcing bars are located inside the plastic outer skin. Adjacent plastic outer skins are spirally wound and interconnected to form a telescopic tube. When there is no adhesive force between the plastic outer skin and the plastic reinforcing bars, the telescopic tube may further include a plastic reinforcing bar co-extruded layer. The plastic reinforcing bar co-extruded layer wraps around the plastic reinforcing bars, and the plastic outer skin surrounds the outer wall of the plastic reinforcing bar co-extruded layer. The outer skin of the plastic outer skin is inclined outward. In this utility model, the telescopic tube is made entirely of plastic. Compared with steel wire composite telescopic tubes, the fully plastic telescopic tube is lighter in weight for the same outer diameter, approximately 30% to 45% lighter. Because there are no steel wires, its extension and contraction are more gentle and unrestricted, requiring less force. Since there are no steel wires, the all-plastic material is more conducive to recycling and reuse, reducing environmental pollution. However, the inner wall of this flexible tube structure is not smooth, making it prone to dust and stain accumulation. Utility Model Content

[0006] The purpose of this utility model is to address the different requirements for the cross-sectional shape of hoses in different scenarios. The shape of the hose varies in different scenarios, but most hoses are currently circular, with limited functionality and poor applicability. Therefore, a spiral hose is proposed.

[0007] To achieve the above objectives, this utility model adopts the following technical solution: a spiral flexible hose.

[0008] The device includes a tubing with a connecting rib structure. The connecting rib structure is wound synchronously with the tubing, so that the inner wall forms a flexible tube of different shapes, and the outer wall forms a spiral rib wound around the flexible tube.

[0009] As a further description of the above technical solution:

[0010] The connecting rib structure includes a plastic rib and a metal wire, with the metal wire located inside the plastic rib.

[0011] As a further description of the above technical solution:

[0012] The tube has several protruding structures, and the connecting rib is located between two of the protruding structures.

[0013] As a further description of the above technical solution:

[0014] The cross-section of the hose can be rectangular, elliptical, round at both ends with a rectangular middle section, or round at both ends with an elliptical middle section, but is not limited to the above shapes.

[0015] In summary, due to the adoption of the above technical solution, the beneficial effects of this utility model are:

[0016] 1. In this utility model, by providing a connecting rib structure on the tube skin, the inner wall of the tube skin is formed into a flexible tube after being wound, and a spiral rib is formed on the outer wall of the flexible tube. The connecting rib structure includes plastic ribs and metal wires, with the metal wires located inside the plastic ribs. This structure can produce flexible tubes with various irregular cross-sections according to requirements through the cooperation of the connecting ribs and the tube skin. The irregular shapes include rectangular, elliptical, rectangular with round ends and rectangular with middle, and elliptical with round ends and elliptical with middle, but are not limited to the above shapes, thus improving applicability. The tube skin gives the flexible tube the function of being wound into various shapes, and the connecting rib structure assists in supporting the formation of the flexible tube after winding, making it less prone to deformation.

[0017] 2. In this utility model, several protruding structures are provided on the tube skin, and the connecting rib structure is connected between two protruding structures. This structure enables the formed hose to have a certain compression and bending function, thereby improving the flexibility of the formed hose.

[0018] 4. In this utility model, after adding metal wires inside the plastic ribs, the cross-section of the tube can be extruded into various shapes without springing back, such as rectangle, ellipse, rectangle with round ends and middle, ellipse with round ends and middle, etc. (the shape is not limited to these). When the tube is made into an irregular shape, the height of the accessories at the bend of the floor brush tube can be reduced, thereby reducing the overall height of the floor brush. In this way, it can clean narrower areas in the environment and effectively improve the applicability of the product.

[0019] 5. In this utility model, by setting a connecting rib structure, the metal wire inside the plastic rib improves the hose's resistance to negative pressure. Attached Figure Description
