New description: [New technical field] This is a kind of nylon spiral tube, especially a spiral type wave tube. A metal mesh coating is cross-woven on the outer circumference of the pipe diameter by stainless steel wire, which is used for mechanical piping. It can prevent high temperature iron filings, high temperature resistance, explosion proof, static electricity, and electromagnetic wave interference. [Prior Art] It is found that the traditional wave tube structure is excellent in flexibility, and the pipe and piping are easy. It has become the main electrical wiring line to replace the PVC pipe. The conventional wave tube is shown in Figure 5, for example. (A) and (B) are general plastic extrusion molding tubes, the main feature of which is that the wall of the wave tube is composed of a plurality of angular or semi-circular ring-shaped irregularities, and inside the pipe diameter and The outer circumferences are respectively formed with a plurality of angular or semi-circular undulating surfaces, and the angular or semi-circular irregularities are parallel to each other instead of the spiral continuous undulating surface. Further, Fig. (C) is a general metal spiral tube which is mainly formed by winding a continuous strip-shaped thin metal crucible into a spiral shape, so that a plurality of spiral continuous undulating surfaces are formed on the inner side and the outer circumference of the pipe diameter, respectively. The above-mentioned conventional plastic extrusion molding tube has the characteristics of flexibility, but for special purposes such as mechanical piping, it does not have the functions of anti-pressure, anti-iron filings high temperature, explosion-proof, anti-electromagnetic interference, etc.; It is easy for the skilled person to think about woven a metal coating on the outer circumference of the pipe diameter of the general plastic extrusion molding tube or to solve the above problems, but the non-spiral wave tubes cannot be applied to the currently used box joints. The distribution box is connected, and the box connector suitable for its construction must be separately developed, so the considerable development cost and time of the M294153 is required. In addition, the conventional metal spiral pipe is used for mechanical piping. Although it has the functions of preventing high temperature, explosion-proof, and electromagnetic wave interference of iron filings, it cannot be waterproof and pressure-resistant. At the same time, the winding forming structure is cut off during installation and cutting. Retraction makes the installation difficult, and sharp edges are formed on the slit, which can cut the hand and the insulating skin of the cable. [New content] The main purpose of this creation is to provide a metal woven mesh covered nylon spiral tube, which can be used for mechanical piping to prevent high temperature iron filings, high temperature resistance, explosion proof, static conduction, electromagnetic wave interference resistance, tensile strength and tensile strength. . In order to achieve the above and other objects, the present invention relates to a nylon woven tube coated with a metal woven mesh, which comprises a spiral wave tube extruded from a plasticized substrate such as nylon, on the inner diameter surface of the spiral wave tube. And a continuous spiral groove is formed on the outer diameter surface, and a metal mesh coating layer is cross-woven on the outer circumference of the spiral wave tube by a plurality of stainless steel wires. In this way, in addition to the flexibility of the spiral tube, the stainless steel mesh coating layer has an outer layer of isolation layer, so that the internal insulation effect is good when used for mechanical piping, and the external can prevent high temperature iron filings and resistance. High temperature, explosion-proof, static electricity, anti-electromagnetic interference, anti-tension and tensile strength, and the product is light weight and easy to handle. According to the spiral tube of the present invention, when used for mechanical piping, the slit of any cross section can be connected to the connecting hole of the wiring box by a special metal-made plastic tube-shaped box joint made of metal or plastic. There is no need to develop a special special box connector, and it can improve the shortcomings of the traditional metal wave tube incision and the sharp incision will cut the hand. This is another purpose of the creation. The present invention will be further described with reference to the embodiments. This embodiment is only a preferred example and is not intended to limit the scope of implementation of the present invention. Get the best understanding. First, referring to Fig. 1, the nylon spiral tube 1 coated with the metal woven mesh basically comprises a spiral wave tube 10 formed by extruding a plasticized substrate such as nylon, that is, the spiral wave tube 10 Inner diameter surface and outer diameter • On the surface, a continuous spiral groove l〇a, 10b is formed, and a metal mesh is cross-woven on the outer circumference of the spiral wave tube 1 by a plurality of stainless steel wires. Layer 11. In addition to greatly increasing the flexibility of the spiral tube 1, the stainless steel mesh coating layer 11 has an outer layer of isolation layer, so that it is used for mechanical piping, and the internal insulation effect is good, and the external surface can prevent high temperature iron filings and resistance. High temperature, explosion-proof, static electricity, anti-electromagnetic interference, anti-tension and tensile strength, and can improve the shortcomings of the traditional metal wave tube incision will be inward and sharp cut will cut hands. * Please refer to Figures 2 and 3 again. When the spiral tube 1 according to the present invention is used for mechanical piping, the slit of any cross section can be passed through a box joint such as a box joint 2 for a conventional metal wave tube. To be connected in the connection hole of the wiring box (not further explained because this creation does not involve the improvement of this part), as shown in the figure is a metal box joint 2, which includes a box end 2a and a a pipe end 2b, wherein the inner side of the pipe end 2b receives an inner bushing 20, and one end of the inner bushing 20 is formed with an annular flange portion 20a corresponding to the inner diameter of the spiral tube 1 And a M294153 notch portion 20b is formed on one side of the flange portion 20a, and the notch portion 20b can be inserted into the groove l〇a of the inner diameter of the spiral tube 1 by rotating the inner liner 20, and the ring is made at the same time. The flange 20a is engaged with the groove l〇a (as shown in FIG. 3), and then the end of the spiral tube 1 is fixed by the inner liner 21 and the nut portion 22. In the tube end 2b of the cartridge joint 2. As shown in Fig. 4, the nylon spiral tube 1 covered by the metal woven mesh is combined with another conventional plastic box joint 2'. As shown in the figure, the box joint 2' includes a box end. 2a and a tube end 2b, an inner bushing 30 is formed inside the pipe end 2b#, and the inner bushing 30 is composed of an inner liner 31 and an outer liner 32. A receiving space 3 3 is formed between the two, and a groove 31a corresponding to the inner diameter of the inner diameter of the spiral tube 1 is formed on the outer circumference of the inner tube 3 1 , and the inner bush 30 can be rotated. The end portion of the spiral tube 1 is received in the receiving space 33, and the screw bud 31a of the inner tube 31 is engaged in the groove 10a of the inner diameter of the spiral tube 1, but by a nut portion 2 2 The end of the spiral tube is fixed in the tube end 2b of the cartridge joint 2. * The above are only the preferred embodiments of this creation, and are not limited to the scope of this creation, that is, the equivalent changes and modifications made without departing from the scope of the patent application should remain within the scope of this creation. In summary, the nylon spiral tube covered by the created metal woven mesh is used for mechanical piping. In addition to the greatly increased flexibility, the outer layer of the stainless steel mesh has a layer of insulation, which not only has good internal insulation effect, but also prevents external heat.
