[0020] Clearly, the described embodiments are merely a part of the embodiments of the present application, but not all the embodiments. Based on the embodiments of the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the protection scope of the present application.
[0021] Please refer to Figures 1-4 The utility model provides the following technical scheme: a DC power cord with anti-winding function, including line body 1, one end of line body 1 is connected with first connector 2, the other end of line body 1 is connected with second connector 3, and four elastic strips 4 are embedded on the outer wall of line body 1 at equal intervals.
[0022] Line body 1, first connector 2 and second connector 3 constitute the DC power cord related in the technical scheme.
[0023] A group of tightening rings 5 are sleeved on the outer wall of the four elastic strips 4 at equal intervals, and the tightening rings 5 are made of flexible rubber material.
[0024] Preferably, four installation grooves 11 are formed on the outer wall of line body 1 at equal intervals, and a group of clamping blocks 12 are installed on the inner wall of the installation grooves 11 at equal intervals.
[0025] A group of embedded grooves 41 are formed at the bottom of the elastic strip 4 at equal intervals, and a group of limiting grooves 42 are formed on the surface of the elastic strip 4 at equal intervals.
[0026] The embedded groove 41 is matched in size with the clamping block 12, and the number of the embedded grooves 41 is matched with the number of the clamping blocks 12.
[0027] In specific use, the embedded groove 41 and the clamping block 12 are connected in interference, and the clamping block 12 is made of flexible rubber material, so that when the elastic strip 4 is installed in the installation groove 11, a preliminary fixed structure is formed.
[0028] Preferably, four convex strips 51 are installed on the inner wall of the tightening ring 5 at equal intervals, and the outer wall on the other side of each convex strip 51 is in arc structure.
[0029] Each tightening ring 5 is clamped with the limiting groove 42 on the elastic strip 4 through the four convex strips 51.
[0030] In specific use, the four elastic strips 4 are installed in the corresponding installation grooves 11, and the embedded groove 41 at the bottom of the elastic strip 4 is accurately clamped with the clamping block 12 on the inner wall of the installation groove 11.
[0031] When the four elastic strips 4 are successfully installed according to the established steps, the next step is to set the tightening ring 5 on the four elastic strips 4 and the outer wall of the wire body 1. Once the tightening ring 5 is completely installed in place, the four elastic strips 4 are effectively fixed on the wire body 1.
[0032] In actual use, the wire body 1 often faces various complex environments and challenges, and at this time, the elastic strips 4 can flexibly adapt to various deformations by virtue of their elastic properties, continuously providing the necessary support force for the wire body 1 to ensure that it always maintains a good vertical state. This feature greatly reduces the risk of the wire body 1 being entangled or twisted due to external forces or its own weight, effectively extending the service life of the wire body 1 and improving overall work efficiency and safety.
