Description

Technical Field

[0001] The utility model relates to the technical field of electrothermal films, and more specifically, to a nano-scale graphene electrothermal film. Background Art

[0002] The graphene electrothermal film is a new type of electrothermal material with many unique advantages and characteristics. First of all, the graphene electrothermal film has extremely high electrical conductivity, which enables it to quickly conduct electric energy, thereby achieving an efficient heating effect. Secondly, the graphene electrothermal film can uniformly heat the entire surface, making the heating effect more uniform and avoiding the problems of local overheating or uneven temperature that may occur in traditional heating methods.

[0003] In addition, the graphene electrothermal film also has the characteristics of a thin design and can be flexibly applied to objects with various curved surfaces and sizes, which provides more possibilities for the design and manufacture of electrothermal products. At the same time, the graphene electrothermal film also has low energy consumption and high energy conversion efficiency, and can provide sufficient heating effect at a low power, thus achieving the goal of energy conservation and environmental protection.

[0004] However, the graphene electrothermal film in the prior art consists of a base material, graphene nanosheets, a conductive material, an insulating film, and a plug. The plug is connected to the graphene nanosheets and sealed by clay and insulating tape. However, in the actual use process, the sealing method only using clay and insulating tape cannot withstand the tensile force applied to the plug wire, and is prone to problems such as loosening or even detachment of the connection due to pulling, which poses a certain safety hazard. In view of this, we propose a nano-scale graphene electrothermal film. Summary of the Utility Model

[0005] The purpose of the utility model is to overcome the deficiencies of the prior art, meet the actual needs, and provide a nano-scale graphene electrothermal film to solve the technical problem that the current graphene electrothermal film is mostly sealed by clay and insulating tape, and in the actual use process, the sealing method only using clay and insulating tape cannot withstand the tensile force applied to the plug wire, and is prone to problems such as loosening or even detachment of the connection due to pulling, which poses a certain safety hazard.

[0006] To solve the above technical problems, the utility model provides the following technical solution: a nano-scale graphene electrothermal film, including a heating component and a connection component arranged on the heating component;

[0007] The connecting component includes a C-shaped clamp. One side of the C-shaped clamp is provided with a cavity, and a cavity groove is provided in the C-shaped clamp. An anti-disengagement mechanism is rotatably arranged between the top and bottom of the cavity groove. One side of the C-shaped clamp is provided with a through hole passing through the cavity groove, and the through hole is communicated with the cavity. A wire passing through the anti-disengagement mechanism is movably arranged in the through hole, and the locking action of the wire is realized through the anti-disengagement mechanism;

[0008] The anti-disengagement mechanism includes two shaft rods. Both shaft rods are rotatably arranged between the top and bottom of the cavity groove. Cam wheels are rotatably arranged on the outer edge surfaces of both shaft rods. Locking grooves for arranging the wire are provided on the outer edge surfaces of both cam wheels.

[0009] In the utility model, the wire is clamped by two cam wheels. When the wire is pulled, the two cam wheels arranged on the two shaft rods will be driven to rotate synchronously, so as to reduce the distance between the two cam wheels, thereby completing the clamping and positioning of the wire, avoiding the problems of connection loosening or even disconnection caused by pulling, and eliminating potential safety hazards.

[0010] Preferably, the heating component includes a base body. A graphene nanosheet is arranged at the center of the base body, and a plurality of installation grooves are equidistantly arranged at the top and bottom of the base body.

[0011] Preferably, conductive bars are fixedly arranged in a plurality of the installation grooves, and insulating layers covering the plurality of conductive bars are arranged on both sides of the graphene nanosheet, and the insulating layers are abutted against the inner side of the base body.

[0012] Preferably, an opening for arranging the C-shaped clamp is provided on one side of the base body, and the graphene nanosheet and the two insulating layers are jointly arranged in the cavity.

[0013] Preferably, a plurality of round holes communicating with the cavity are equidistantly arranged at the top and bottom of the C-shaped clamp, and a locking nail is jointly arranged in two opposite round holes. Grooves are formed at the top and bottom of the locking nail under pressure.

[0014] Preferably, a plurality of through holes one for the locking nail to pass through are equidistantly arranged on one side of the graphene nanosheet, and a plurality of through holes two for the locking nail to pass through are equidistantly arranged on one side of the two insulating layers.

[0015] Compared with the prior art, the beneficial effects of the utility model are:

[0016] 1. The utility model realizes the locking of the wire through the anti - detachment mechanism arranged in the upper cavity of the C - type clamp. When the wire is pulled, it will synchronously drive the rotation of two cams arranged on two shaft rods, thereby reducing the distance between the two cams, and thus completing the clamping and positioning of the wire to avoid the problem of loosening or even detachment of the connection caused by pulling, eliminating potential safety hazards.

[0017] 2. The utility model also fixes the C - type clamp on the graphene nanosheet and two insulating layers through multiple locking nails. During fixation, the locking nails are passed through the through - hole one on the graphene nanosheet and the two insulating layers and the through - hole two, and a tool is used to apply pressure to the locking nails from both sides, thereby forming grooves at both ends of the locking nails, realizing the fixation of the locking nails in the C - type clamp, and thus realizing the fixation of the C - type clamp on the graphene nanosheet and the two insulating layers, and completing the connection to avoid the problem of detachment under tension.
