Detailed Description of the Preferred Embodiments

[0015] The technical solutions of this patent will be further described in detail below in conjunction with the specific embodiments.

[0016] As Figures 1-4 shown, the present invention provides a technical solution: an electric heating nickel-chromium alloy wire for physical therapy massage, including an alloy wire body 1, an anti-corrosion insulation layer 5 is coated on the outer circumferential surface of the alloy wire body 1. Due to the anti-corrosion insulation layer 5, the anti-corrosion insulation layer 5 improves the anti-corrosion property of the alloy wire body 1, extends its service life, and reduces its corrosion probability. An inner sheath 6 is provided on the anti-corrosion insulation layer 5, an anti-rotation block 10 is fixedly connected to the inner sheath 6, and the outer sheath 4, the second blocking ring 9 and the first blocking ring 2 are all made of rubber.

[0017] A plurality of first blocking rings 2 are fixedly connected to the inner sheath 6, and the plurality of first blocking rings 2 are equidistantly distributed on the inner sheath 6. A second blocking ring 9 is arranged on one side of the two first blocking rings 2 close to each other. Six anti-rotation grooves 8 are formed in the second blocking ring 9, and six anti-rotation blocks 10 are arranged on one side of the two first blocking rings 2 close to each other. Since the second blocking ring 9 and the anti-rotation blocks 10 are made of plastic, they can play a buffering role and can better protect the alloy wire body 1.

[0018] The number of the second blocking rings 9 is several. An outer sheath 4 is fixedly connected to the several second blocking rings 9. A nylon wear-resistant layer 3 is coated on the outer circumferential surface of the outer sheath 4. Due to the nylon wear-resistant layer 3, the nylon wear-resistant layer 3 makes the outer sheath 4 have good wear resistance, avoiding the phenomenon of damage to the outer sheath 4 after long-term use. A plurality of toughening wires 7 are fixedly connected inside the outer sheath 4. The toughening wires 7 are composed of several strands of ultra-high molecular weight polyethylene fiber filaments. Due to the toughening wires 7, the tensile property of the outer sheath 4 is improved, and then the tensile property of the alloy wire body 1 is improved.

[0019] The working principle of the present utility model is as follows:

[0020] When the outer sheath 4 is sleeved on the inner sheath 6, the second blocking ring 9 is located between the two first blocking rings 2, and the anti-rotation blocks 10 are located inside the anti-rotation grooves 8. The friction between the second blocking ring 9 and the first blocking ring 2 can closely fit the outer sheath 4 and the inner sheath 6. The cooperation of the anti-rotation grooves 8 and the anti-rotation blocks 10 can also prevent the inner sheath 6 and the outer sheath 4 from rotating relative to each other. The outer sheath 4 is exposed to the air and is prone to friction and rupture with objects. The nylon wear-resistant layer 3 makes the outer sheath 4 have good wear resistance.

[0021] In the description of the present utility model, it should be noted that unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood through specific situations.

[0022] The above has described the preferred embodiments of the present patent in detail, but the present patent is not limited to the above embodiments.
