Description

Technical Field

[0001] This utility model is a fire hose that is easy to reel in, belonging to the field of fire hoses. Background Technology

[0002] Fire hoses are flexible tubes used to transport high-pressure water or flame-retardant liquids such as foam. Traditional fire hoses have a rubber inner lining and an outer layer covered with woven linen. Advanced fire hoses are made of polymer materials such as polyurethane. Both ends of a fire hose have metal connectors, allowing connection to another hose to extend the distance or to nozzles to increase the liquid spray pressure.

[0003] Existing fire hoses need to be secured with cable ties or ropes after being rolled up. However, before being tied with cable ties or ropes, the hoses are prone to loosening due to their elasticity, which affects the winding and securing process. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a fire hose that is easy to roll up, so as to solve the problem that existing fire hoses need to be fixed with cable ties or ropes after being rolled up. However, before being tied with cable ties or ropes, the hose body has a certain elasticity, which can easily cause it to loosen and affect the rolling and fixing work.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a fire hose that is easy to reel in, comprising a hose body and a hose fastener; the hose fastener is located at the end of the hose body; the hose body includes a flexible magnetic edging and a double-layer tube, wherein the flexible magnetic edging has two symmetrically wrapped around both sides of the double-layer tube, so as to pre-position the double-layer tube by magnetic positioning when the fire hose is reeled in, preventing it from unraveling.

[0006] Furthermore, to improve the overall connection strength, the double-layer tube body includes a braided outer tube and an inner tube fixed inside the outer tube, with connecting edges extending from both sides of the outer tube to be adapted to the flexible magnetic edging.

[0007] Furthermore, in order to perform magnetic positioning during winding, the flexible magnetic edging includes an edging body fixedly attached to the connecting edge and a flexible magnetic strip disposed within the interlayer of the edging body.

[0008] Furthermore, for overall pre-positioning, the flexible magnetic strip is of equal length to the outer tube and the two are parallel to each other.

[0009] Furthermore, in order to improve the magnetic attraction effect, the cross-section of the flexible magnetic strip is a horizontally placed U-shaped structure, with the upper horizontal edges of the U-shaped structure located above the connecting edge and the lower horizontal edges of the U-shaped structure located below the connecting edge.

[0010] Furthermore, to ensure waterproof and corrosion-resistant performance, the outer tube is woven from one or two of polyester, linen, nylon, and PVC.

[0011] Furthermore, to improve waterproof performance, the inner tube is made of rubber or PU material.

[0012] Furthermore, to improve wear resistance, the outer wall of the outer tube is coated with a polyurethane coating.

[0013] The beneficial effects of this utility model are: the flexible magnetic edging in the fire hose is symmetrically wrapped around both sides of the double-layer pipe body, and is automatically attracted and positioned by magnetic force when it is rolled up, avoiding the phenomenon that the fire hose will unravel before it is fixed after being rolled up in the traditional way.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments. Example 1

[0017] Please see Figure 1 , Figure 2 , Figure 3 This utility model provides a technical solution for fire hoses that are easy to reel in: its structure includes a hose body 1 and a hose fastener 2; the hose fastener 2 is located at the end of the hose body 1; the hose body 1 includes a flexible magnetic edging 11 and a double-layer tube 12, the flexible magnetic edging 11 has two symmetrically wrapped around both sides of the double-layer tube 12, so that when the fire hose is reeled in, the double-layer tube 12 is pre-positioned by magnetic positioning to prevent it from unraveling.

[0018] To improve the overall connection strength, the double-layer tube body 12 includes a braided outer tube 121 and an inner tube 122 fixed inside the outer tube 121. Both sides of the outer tube 121 have connecting edges 123 that are adapted to the flexible magnetic edging 11.

[0019] For magnetic positioning during winding, the flexible magnetic edging 11 includes an edging body 111 fixedly attached to the connecting edge 123 and a flexible magnetic strip 112 disposed in the interlayer of the edging body 111. The edging body 111 and the connecting edge 123 are fixedly connected by heat-pressing, which has the function of preventing excessive expansion of the outer tube 121 after being flushed with water. The edging body 111 is made of polyurethane rubber, which has the advantages of wear resistance and tear resistance.

[0020] Among them, the flexible magnetic strip 112 is an existing technology. It is a bendable and cuttable magnetic material with a thickness of 0.5mm-1.2mm, preferably 1mm. While ensuring the magnetic positioning effect, it has strong flexibility to prevent affecting the normal operation of the fire hose.

[0021] For overall positioning, the flexible magnetic strip 112 and the outer tube 121 are of equal length and parallel to each other.

[0022] To improve the magnetic attraction effect, the cross-section of the flexible magnetic strip 112 is a horizontally placed U-shaped structure, with the upper horizontal edge of the U-shaped structure located above the connecting edge 123 and the lower horizontal edge of the U-shaped structure located below the connecting edge 123.

[0023] To ensure waterproof and corrosion-resistant performance, the outer tube 121 is woven from one or two of polyester, linen, nylon, and PVC, with polyester being the preferred material.

[0024] To improve waterproof performance, the inner tube 122 is made of rubber or PU material, preferably rubber. Example 2
