Abstract
Description
Technical Field
[0001] This utility model relates to the field of metal hose technology, and in particular to a novel metal hose. Background Technology
[0002] A flexible metal tube is a type of flexible metal tube that can be bent freely. In everyday life, products such as headphone microphones, lamp stands, and phone stands all have a flexible metal tube in place so that the working end of these products can be bent freely.
[0003] See patent document CN2022200555185, which discloses a flexible metal hose comprising steel wire and iron wire. The steel wire is continuously and equidistantly helically bent to form a helical tubular body, and helical grooves are formed on the outer circumferential side of the helical tubular body. The iron wire is helically wound within the helical grooves. This flexible metal hose can be viewed as the iron wire being screwed into the helical grooves of the steel wire through helical rotation. In practical applications, driven by other external forces, the iron wire can unscrew from the helical steel wire, causing the steel wire to separate from the iron wire. This results in the top or bottom of the flexible metal hose losing its free bending performance, leading to inconvenience in use. Summary of the Invention
[0004] The technical problem to be solved by this utility model is to provide a new type of metal hose, which improves the limiting structure of the metal hose to fix the iron wire relative to the steel wire, thus solving the problem of inconvenience in previous use.
[0005] To address the aforementioned technical problems, this utility model discloses a novel metal flexible hose, comprising steel wire and copper wire. The steel wire is bent in a spiral shape to form a first spiral body, and a spiral groove is formed on the outer peripheral side of the first spiral body. The copper wire is bent in a spiral shape to form a second spiral body, and the second spiral body is screwed into the spiral groove of the first spiral body. The metal flexible hose also includes a soft sheath, which is fitted on the outside of the first spiral body and the outside of the second spiral body. The outer peripheral sides of both the first and second spiral bodies are tightly fitted with the soft sheath.
[0006] The soft sheath is made of plastic.
[0007] The soft sheath is formed on the outer periphery of the first and second helices by injection molding.
[0008] The thickness of the soft sheath is 0.1mm to 2mm.
[0009] The top and / or bottom ends of the wire extend outward to form a hook.
[0010] The copper wire is brass wire.
[0011] The steel wire is made of piano steel.
[0012] The inner wall of the soft sheath is coated with adhesive.
[0013] Compared with the prior art, the present invention has the following advantages: by setting a soft sheath, which is fitted on the outer periphery of the spiral body, the soft sheath limits the first spiral body and the second spiral body, avoiding relative movement between the steel wire and the copper wire, solving the problem of inconvenience in previous use. The overall structure is simple and compact, and easy to mass-produce. In addition, the soft sheath can also play a protective role, preventing the first spiral body or the second spiral body from being scratched. Attached Figure Description

[0017] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention 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 invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] The terms "first," "second," etc., in the specification, claims, and accompanying drawings of this utility model are used to distinguish different objects, not to describe a specific order. Furthermore, the terms "comprising" and "having," and any variations thereof, are intended to cover non-exclusive inclusion. For example, a process, method, apparatus, product, or server that includes a series of steps or units is not limited to the listed steps or units, but may optionally include steps or units not listed, or may optionally include other steps or units inherent to these processes, methods, products, or servers.
[0019] In this document, the term "embodiment" means that a particular feature, structure, or characteristic described in connection with an embodiment may be included in at least one embodiment of the present invention. The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.
[0020] This utility model discloses a specific embodiment of a novel metal flexible hose, please see... Figure 1 and Figure 2 The device comprises a steel wire 1 and a copper wire 2. The steel wire 1 is bent in a spiral shape to form a first spiral 31, and spiral grooves are formed on the outer circumferential surface of the first spiral 31. The copper wire 2 is bent in a spiral shape to form a second spiral 32, and the second spiral 32 is screwed into the spiral grooves of the first spiral 31. It should be noted that the whole consisting of the first spiral 31 and the second spiral 32 is a metal flexible hose structure in the prior art, and both can be produced and wound using existing spring manufacturing methods. In the whole consisting of the two, the copper wire 2 can be rotated out of the first spiral 31 formed by winding the steel wire 1.
[0021] As an improvement, the metal hose also includes a soft sheath 4, which is fitted over the outer side of the first helix 31 and the second helix 32. Preferably, the soft sheath 4 is a plastic sheath, formed on the outer periphery of the first helix 31 and the second helix 32 by injection molding. In other embodiments, the soft sheath 4 can also be made of materials such as fiber fabric, silicone, or composite film, as long as it can achieve a shrinking and tightening effect, thereby ensuring that the outer periphery of both the first helix 31 and the second helix 32 are tightly fitted with the soft sheath 4. Utilizing the structural characteristics of the soft sheath 4, the second helix 32 is fixed relative to the first helix 31, preventing the second helix 32 from shifting relative to the first helix 31.
[0022] In this embodiment, the thickness of the soft sheath 4 is 0.1mm to 2mm. As a preferred option, the thickness of the soft sheath 4 is 1mm. This ensures that the soft sheath 4 has sufficient structural strength and can provide sufficient clamping force to wrap the steel wire 1 and the copper wire 2.
[0023] To facilitate the connection and fixation of the metal flexible hose to external parts, a hook 11 extends outward from the top end of the steel wire 1. In other embodiments, a hook 11 can also be provided at the bottom end of the steel wire 1, which can be selectively provided according to actual needs.
[0024] As a preferred option, copper wire 2 is brass wire 2, and steel wire 1 is piano wire. Brass is an alloy composed of copper and zinc. Brass composed of only copper and zinc is called ordinary brass, while alloys composed of two or more elements are called special brass. Brass has strong wear resistance, which can extend the service life of metal hoses. Piano wire 1 is a high-strength carbon steel spring material that is cold-drawn after lead bath quenching. It is commonly found in round wire form. Piano wire 1 has high tensile strength, elastic limit, and fatigue resistance. Piano wire 1 is mainly used to make dynamic load springs.
[0025] In other embodiments, the soft sheath 4 can also be fixed to the first helix 31 and the second helix 32 by adhesive. Specifically, the inner wall of the soft sheath 4 is coated with adhesive, and the adhesive properties of the adhesive are used to bond and fix it to the first helix 31 and the second helix 32 respectively.
[0026] In this embodiment, the metal flexible hose features a soft sheath 4, which is fitted around the outer periphery of the spiral body. This soft sheath 4 limits the movement of the first spiral body 31 and the second spiral body 32, preventing relative movement between the steel wire 1 and the copper wire 2. This solves the previous problem of inconvenience in use. The overall structure is simple and compact, facilitating mass production. In addition, the soft sheath 4 also provides protection, preventing scratches from the first spiral body 31 or the second spiral body 32. Furthermore, even if the first spiral body 31 or the second spiral body 32 breaks, it will not cause separation between the two ends of the metal flexible hose, as the soft sheath 4 serves as a connector.
[0027] Finally, it should be noted that the novel metal hose disclosed in this utility model embodiment is only a preferred embodiment of this utility model and is only used to illustrate the technical solution of this utility model, not to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of this utility model.
