[0016] (1) By setting a protective layer, a first wear-resistant layer, a second wear-resistant layer and a limiting rod, the first wear-resistant layer inside the protective layer has excellent corrosion resistance, chemical corrosion resistance, oil resistance, heat resistance, as well as the characteristics of hard coating and strong adhesion, which can increase the corrosion resistance of the power cord.

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 The present invention provides an embodiment of a fire-resistant and flame-retardant power cord with a corrosion-resistant structure, comprising a storage box 1, a rotating shaft 2 movably connected inside the storage box 1, a storage shaft 4 fixedly connected outside the rotating shaft 2, baffles 3 fixedly connected to the upper and lower ends of the storage shaft 4, a rubber sleeve 5 wrapped around the outside of the storage shaft 4, a power cord assembly 10 installed inside the rubber sleeve 5, and a protective structure provided outside the rubber sleeve 5 to prevent corrosion of the rubber sleeve 5 and the power cord assembly 10.

[0026] The protective structure includes a protective layer 9, a first wear-resistant layer 15 and a waterproof layer 17. The outer side of the rubber sleeve 5 is provided with a protective layer 9, the inner side of the protective layer 9 is provided with a waterproof layer 17, the outer side of the waterproof layer 17 is coated with a second wear-resistant layer 16, the outer side of the second wear-resistant layer 16 is coated with a first wear-resistant layer 15, and the outer side of the power cord assembly 10 is provided with a shielding layer 13.

[0027] The first wear-resistant layer 15 and the second wear-resistant layer 16 are made of epoxy resin coating and polyurethane coating. The second wear-resistant layer 16 is disposed between the first wear-resistant layer 15 and the waterproof layer 17. A connector 6 is installed at the bottom left side of the rubber sleeve 5 and the power cord assembly 10, and a plug 7 is installed at the top left side of the rubber sleeve 5 and the power cord assembly 10.

[0028] Specifically, such as Figure 1 , Figure 2 and Figure 3 As shown, the first wear-resistant layer 15 inside the protective layer 9 has excellent corrosion resistance, chemical corrosion resistance, oil resistance, heat resistance, and features such as hard coating and strong adhesion, which can increase the corrosion resistance of the power cord. The second wear-resistant layer 16 can not only further increase the corrosion resistance, but also increase the wear resistance of the rubber sleeve 5, thereby increasing the service life of the power cord. The waterproof layer 17 can prevent water from seeping into the interior of the rubber sleeve 5 and affecting the power cord assembly 10.

[0029] A handle 8 is fixedly connected to the top of the rotating shaft 2, a connecting block 20 is fixedly connected to the top of the storage box 1, a pull plate 22 is provided on the left side of the connecting block 20, a limit rod 19 is fixedly connected to the right side of the pull plate 22, a spring 21 is fixedly connected between the pull plate 22 and the connecting block 20, a fixing hole 18 is provided on the outer side wall of the top of the rotating shaft 2, a limit groove 23 is fixedly connected to the left side of the top of the storage box 1, a limit slider 24 is provided inside the limit groove 23, a stop block 25 is fixedly connected to the top of the limit slider 24, multiple sets of fixing holes 18 are provided, the fixing holes 18 are distributed in a ring at equal intervals on the outer side wall of the top of the rotating shaft 2, the spring 21 is provided on the left side outside the limit rod 19, the limit slider 24 slides inside the limit groove 23, and the stop block 25 is provided on one side of the pull plate 22;

[0030] Specifically, such as Figure 1 and Figure 4 As shown, when the power cord needs to be stored, pull plate 22 is pulled. Pull plate 22 pulls limit rod 19 to disengage from fixing hole 18. Then push stop 25 to move to one side of pull plate 22 to limit pull plate 22. After limiting pull plate 22, rotate handle 8. Rotate handle 8 through rotating shaft 2 to drive storage shaft 4 to store the power cord. After storage is completed, pull stop 25 to disengage from one side of pull plate 22, so that pull plate 22 can be unfixed. Spring 21 uses its own elasticity to make limit rod 19 embedded in the fixing hole 18 to limit rotating shaft 2. The length of the power cord exposed can be controlled according to the needs of power cord storage.

[0031] The inner wall of the rubber sleeve 5 is provided with a fire-resistant and flame-retardant layer 14. The inside of the rubber sleeve 5 is filled with a filling sponge 11. The inside of the filling sponge 11 is provided with elastic particles 12. The filling sponge 11 and the elastic particles 12 are arranged between the power cord group 10. There are multiple sets of elastic particles 12.

[0032] Specifically, such as Figure 2 As shown, the filling sponge 11 and elastic particles 12 inside the rubber sleeve 5 can protect the power cord assembly 10 inside the rubber sleeve 5. When the rubber sleeve 5 is squeezed, the filling sponge 11 and elastic particles 12 can protect it. When the pressure is removed, the filling sponge 11 and elastic particles 12 will cause the rubber sleeve 5 to spring back to its original position, thereby preventing the power cord from deforming during use.

[0033] Working Principle: In use, the first wear-resistant layer 15 inside the protective layer 9 of this invention possesses excellent corrosion resistance, chemical corrosion resistance, oil resistance, heat resistance, and features a hard coating and strong adhesion, thus increasing the corrosion resistance of the power cord. The second wear-resistant layer 16 not only further enhances corrosion resistance but also increases the wear resistance of the rubber sleeve 5, thereby extending the service life of the power cord. The waterproof layer 17 prevents water from seeping into the interior of the rubber sleeve 5 and affecting the power cord assembly 10. The filling sponge 11 and elastic particles 12 inside the rubber sleeve 5 protect the power cord assembly 10. When the rubber sleeve 5 is compressed, the filling sponge 11 and elastic particles 12 provide protection; when the pressure is released, the filling sponge 11... The elastic particles 12 cause the rubber sleeve 5 to spring back to its original position, thus preventing the power cord from deforming during use. When the power cord needs to be stored, pull the pull plate 22. The pull plate 22 pulls the limiting rod 19, causing the limiting rod 19 to disengage from the fixing hole 18. Then, push the stop block 25 to move the stop block 25 to one side of the pull plate 22 to limit the pull plate 22. After the pull plate 22 is limited, turn the handle 8. The handle 8 drives the storage shaft 4 through the rotating shaft 2 to store the power cord. After storage is completed, pull the stop block 25 to disengage from one side of the pull plate 22, thus making the pull plate 22 unfixed. The spring 21 uses its own elasticity to make the limiting rod 19 embedded in the fixing hole 18 to limit the rotating shaft 2. The length of the power cord exposed can be controlled according to the needs of power cord storage.

[0034] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
