Description

Technical Field

[0001] This utility model relates to the field of power cord technology, and in particular to a cut-resistant power cord. Background Technology

[0002] A power cord is a power transmission device used for charging or conducting electricity in electrical appliances. It is now widely used in various scenarios and can be adapted to different devices by using different plug terminals. It has the advantages of being easy to use and having a wide range of applications.

[0003] Currently, many traditional power cords only have a single-structure rubber outer sheath. In actual use, due to the usage environment and external factors, the outer sheath is easily cut by external force, resulting in the internal core wires being exposed and failing to provide effective protection, thus posing certain safety hazards. Therefore, there is an urgent need for a cut-resistant power cord. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a cut-resistant power cord.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A cut-resistant power cord includes a power cord core wire, and the outer side of the power cord core wire is sequentially connected to a separator layer, an asbestos layer, a metal mesh layer, a cut-resistant inner sheath layer, a polyester fiber layer, and a cut-resistant outer sheath layer.

[0007] The outer wall of the cut-resistant inner sleeve is provided with a ring array of multiple hard rubber protrusions, each of which fits into the groove of the inner wall of the cut-resistant outer sleeve, and the outer wall of the cut-resistant outer sleeve is provided with a ring array of multiple hard rubber arc-shaped protrusions.

[0008] The hard rubber arc-shaped protrusion has a hole in the middle, and a thin metal wire is embedded in the hole.

[0009] Furthermore, in a preferred configuration, an inner protective sleeve is provided on the outer side of the power cord core.

[0010] Furthermore, in a preferred configuration, the separator layer is wrapped around the outer wall of the power cord core.

[0011] In addition, a preferred structure is that a polyester fiber layer is connected between the cut-resistant inner sleeve and the cut-resistant outer sleeve, and the polyester fiber layer is embedded in the groove by a hard rubber protrusion.

[0012] Furthermore, in a preferred configuration, the hard rubber arc-shaped protrusion is flat and protrudes beyond the outer surface of the cut-resistant outer sheath.

[0013] The beneficial effects of this utility model are as follows:

[0014] In this invention, the power cord core wire is reinforced by an asbestos layer, a metal mesh layer, and cut-resistant inner and outer sheaths to improve overall cut resistance. The cut-resistant inner and outer sheaths are tightly connected by hard rubber protrusions and grooves. Flat, hard rubber arc-shaped protrusions are provided on the outer side of the cut-resistant outer sheath to provide cut resistance, and fine metal wires are provided inside to enhance cut resistance. This effectively improves the overall cut resistance of the cord and ensures the cord's service life and stability. Attached Figure Description

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] Reference Figure 1-3 A cut-resistant power cord includes a power cord core wire 1, and a separator layer 2, an asbestos layer 3, a metal mesh layer 4, a cut-resistant inner sheath layer 5, a polyester fiber layer 6, and a cut-resistant outer sheath layer 7 are sequentially connected to the outside of the power cord core wire 1.

[0021] Among them, the asbestos layer 3 has excellent properties such as high tensile strength, high flexibility, resistance to chemical and thermal erosion, and electrical insulation. It can effectively improve the overall strength and toughness of the power cord to resist external mechanical damage. In addition, the asbestos fibers can disperse and absorb external cutting or tearing forces, thereby preventing the material from breaking.

[0022] Furthermore, the outer wall of the cut-resistant inner sleeve 5 is provided with a ring array of multiple hard rubber protrusions 51, each hard rubber protrusion 51 is matched with the groove 72 of the inner wall of the cut-resistant outer sleeve 7, and multiple hard rubber arc-shaped protrusions 71 are provided in the ring array on the outer wall of the cut-resistant outer sleeve 7.

[0023] Furthermore, a hole is vertically opened through the middle of the hard rubber arc-shaped protrusion 71, and a fine metal wire 73 is embedded in the hole. The fine metal wire 73 has a certain cut resistance. Even if the hard rubber arc-shaped protrusion 71 is cut, the fine metal wire 73 inside can still play a highly efficient cut resistance role.

[0024] Furthermore, an inner protective sleeve 11 is provided on the outside of the power cord core wire 1. The inner protective sleeve 11 plays a basic protective role and is a necessary protective layer for the core wire, which is a standard feature.

[0025] Furthermore, the separator layer 2 is wrapped around the outer wall of the power cord core wire 1.

[0026] Furthermore, a polyester fiber layer 6 is connected between the cut-resistant inner sleeve layer 5 and the cut-resistant outer sleeve layer 7. The polyester fiber layer 6 is embedded in the groove 72 by a hard rubber protrusion 51. The cut-resistant inner sleeve layer 5 and the cut-resistant outer sleeve layer 7 are tightly connected to each other, so that the polyester fiber layer 6 and the cut-resistant inner sleeve layer 5 and the cut-resistant outer sleeve layer 7 form a high-strength, cut-resistant whole.

[0027] Furthermore, the hard rubber arc-shaped protrusion 71 is flat and protrudes from the outer wall surface of the cut-resistant outer jacket 7. The protruding hard rubber arc-shaped protrusion 71 can effectively block external mechanical damage and to a certain extent prevent it from directly damaging the cut-resistant outer jacket 7 body.

[0028] In this embodiment, when the power cord body is subjected to external force, the raised hard rubber arc-shaped protrusion 71 provided on the outer side of the cut-resistant outer jacket 7 preferentially bears the mechanical cutting damage, thus avoiding direct damage to the cut-resistant outer jacket 7 body.

[0029] At the same time, even after the hard rubber arc-shaped protrusion 71 is cut, the fine metal wire 73 inside it can still provide efficient cut resistance.

[0030] Furthermore, a polyester fiber layer 6 is connected to the inner side of the cut-resistant outer jacket layer 7. The polyester fiber layer 6 has excellent properties such as high strength, wear resistance, and chemical corrosion resistance. When the thread is subjected to external cutting or tearing forces, the polyester fiber can absorb and disperse these forces, and at the same time, it works with the cut-resistant inner jacket layer 5 to form a cut-resistant layer with high integrity and high strength.

[0031] Among them, the outer wall of the cut-resistant inner sleeve layer 5 is still provided with a raised hard rubber strip 51. The hard rubber strip 51 fits into the groove 72 to improve the tightness of the connection, and the setting of the strip can provide a protective effect after the outer structure is damaged.

[0032] In this invention, the power cord core 1 is enhanced in overall cut resistance by an asbestos layer 3, a metal mesh layer 4, and cut-resistant inner and outer sheaths. The cut-resistant inner sheath 5 and the cut-resistant outer sheath 7 are tightly connected by a hard rubber protrusion 51 and a groove 72. A flat, hard rubber arc-shaped protrusion 71 is provided on the outside of the cut-resistant outer sheath 7 to provide cut resistance, and a fine metal wire 73 is provided inside to enhance cut resistance. This effectively improves the overall cut resistance of the cord and ensures the cord's service life and stability.

[0033] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
