[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0020] like Figure 1-4 As shown, the utility model provides a technical solution: a bending-resistant power cord, comprising a power cord body 6, the outer ends of the power cord body 6 are respectively installed with a protective shell 1 and a protective shell 2 3, the side end of the protective shell 1 is fixedly connected with a plurality of plug boards 101, the side end of the protective shell 2 3 is provided with a plurality of slots 301, the top of each slot 301 is provided with a plug hole 302, each slot 301 is adapted to each plug board 101, each plug board 101 is provided with a mounting groove 102, each mounting groove 102 is provided with a limiting mechanism for fixing the protective shell 2 3, the bottom end of the protective shell 1 is fixedly connected with a spiral protective sleeve 4, the bottom end of the protective shell 2 3 is provided with a fixing mechanism for fixing the power cord, During implementation, the protective shell 1 and the protective shell 2 3 are fixedly installed on the side end of the power cord body 6 near the plug position through the limiting mechanism, so as to effectively protect the position that is easy to bend and break, so that it is not easy to bend and break, and the bending resistance of the power cord body 6 is improved. By wrapping the spiral protective sleeve 4 around the outer end of the power cord body 6 in circles, the outer end of the power cord body 6 can be protected, and the bending resistance of the power cord body 6 is improved, thereby improving the protection effect of the power cord body 6, making it difficult for the connection between the plug and the power cord to bend and break, so that the conductor inside the power cord is not easily exposed at the outer end, so that the power cord is not easily damaged, reducing the danger of household appliances during use.

[0021] As an implementation method in this embodiment, Figure 1 and Figure 3As shown, the limiting mechanism includes a spring 2, which is fixedly connected to the inner bottom end of the mounting groove 102, and the top of the spring 2 is fixedly connected to a rectangular plate 201, and the top of the rectangular plate 201 is fixedly connected to a plug rod 202, each plug hole 302 is adapted to each plug rod 202, and the side end of the rectangular plate 201 is fixedly connected to a pull plate 203, and the pull plate 203 extends through the mounting groove 102 to the outer end of the plug plate 101. In practice, by sleeves of the protective shell 1 and the protective shell 2 3 on the side end of the power cord body 6 near the plug position, by pulling each pull plate 203, the rectangular plate 201 is pressed against the spring 2 to shrink. The rectangular plate 201 can drive the plug rod 202 to move toward the inside of the installation groove 102. When the plug rod 202 no longer limits the insertion hole 302, each plug plate 101 is inserted into each slot 301 accordingly. After the pull plate 203 is released, the spring 2 will push the rectangular plate 201 to drive the plug rod 202 to rebound, so that the plug rod 202 is inserted into the insertion hole 302, thereby fixing the side end of the power cord body 6 near the plug position between the protective shell 1 and the protective shell 2 3, effectively protecting the position that is prone to bending and breaking, making it less likely to bend and break, and improving the bending resistance of the power cord body 6.

[0022] As an implementation method in this embodiment, Figure 2 and Figure 4 As shown, the fixing mechanism includes a straight plate 1 5, which is rotatably arranged at the bottom end of the protective shell 2 3, and a plurality of straight plates 2 501 are rotatably arranged at the bottom end of the straight plate 1 5, and an oblique groove 502 is provided between the side end of the straight plate 1 5 and the side end of the straight plate 2 501, and an oblique groove 502 is provided between the side ends of every two adjacent straight plates 2 501, and a fixing sleeve 503 is fixedly connected to the side end of one of the straight plates 2 501, and an arc groove 504 is provided between the side end of the straight plate 1 5 and the side ends of the plurality of straight plates 2 501. In implementation, when the power cord body 6 needs to maintain stronger bending resistance, the spiral protective sleeve 4 is circled around the oblique groove 502 and the outer end of the power cord body 6 so that the spiral The protective cover 4 binds a plurality of straight plates 501 and a power cord body 6 together. When the spiral protective cover 4 is wrapped in the inclined groove 502, it is difficult for the adjacent straight plates 501 to rotate, so that the power cord body 6 is in a straight state and is not easy to bend, so that it is convenient to fix the power cord body 6 on the wall, and it is not easy to collapse, bend or break, thereby improving the protection effect of the power cord body 6, making it difficult for the connection between the plug and the power cord to bend or break, so that the conductor inside the power cord is not easy to be exposed at the outer end, so that the power cord is not easy to be damaged, thereby reducing the danger of household appliances during use.

[0023] Working principle: by putting the protective shell 1 and the protective shell 2 3 on the side end of the power cord body 6 near the plug position, by pulling each pull plate 203, the rectangular plate 201 is pressed against the spring 2 to shrink, and the rectangular plate 201 can drive the plug rod 202 to move toward the inside of the installation groove 102. When the plug rod 202 no longer limits the insertion hole 302, each plug plate 101 is correspondingly inserted into each slot 301. After releasing the pull plate 203, the spring 2 will push the rectangular plate 201 to drive the plug rod 202 to rebound, so that the plug rod 202 is inserted into the insertion hole 302, so that the protective shell 1 and the protective shell 2 3 are fixed at the side end of the power cord body 6 near the plug position, The position that is prone to bending and breaking is effectively protected, making it less likely to bend and break, thereby improving the bending resistance of the power cord body 6. Then, the outer end of the power cord body 6 can be protected by wrapping the spiral protective sleeve 4 around the outer end of the power cord body 6. At this time, the fixed sleeve 503 is clamped on the outer end of the power cord. Since the straight plate 1 5 and the plurality of straight plates 2 501 are rotatably arranged, the power cord body 6 is protected by the spiral protective sleeve 4 at this time. The power cord body 6 can still be flexibly swung, and the flexibility is retained while the bending resistance of the power cord body 6 is improved by the spiral protective sleeve 4. Therefore, it is convenient for people to flexibly adjust the installation direction and position of the power cord body 6.

[0024] When the power cord body 6 needs to maintain stronger bending resistance, the spiral protective sleeve 4 is wrapped around the inclined groove 502 and the outer end of the power cord body 6 in circles, so that the spiral protective sleeve 4 binds the plurality of straight plates 2 501 and the power cord body 6 together. When the spiral protective sleeve 4 is wrapped in the inclined groove 502, it is difficult for the adjacent straight plates 2 501 to rotate, so that the power cord body 6 is in a straight state and is not easy to bend, so that it is convenient to fix the power cord body 6 on the wall, and it is not easy to collapse, bend or break, thereby improving the protection effect of the power cord body 6, making it difficult for the connection between the plug and the power cord to be bent or broken, so that the conductor inside the power cord is not easy to be exposed at the outer end, so that the power cord is not easy to be damaged, thereby reducing the danger of household appliances during use.

[0025] The above embodiments are only used to illustrate the technical solution of the present invention, but not to limit it.
