The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0024] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work shall fall within the scope of protection of this application.

[0025] In the prior art, in order to ensure the life safety of personnel, a signboard with the words "Do not close the switch, someone is working!" is often hung on the operating handle of the disconnected power supply air switch by a rope. However, the operating handle of some power supply air switches is small, and the handle tilts downward after the air switch is disconnected, making it inconvenient to hang the signboard by winding the rope, and since there is no fixing device, the signboard is easily removed from the operating handle of the air switch due to airflow or vibration.

[0026] Therefore, in order to solve the above-mentioned technical problems of the difficulty in hanging the signboard and the unstable hanging of the signboard that is easy to fall off, the embodiment of the present application proposes a hook for the signboard of a secondary power air switch, and the hook is installed on the air switch body to replace the air switch operating handle to hang the retractable signboard. The hook and the base have a reasonable opening, and there is a spherical protrusion on the inner side of the end of the hook part, which can realize the quick hanging of the signboard while preventing the signboard from falling off accidentally. The fitting part allows the hook to fit tightly with the air switch body and is not easy to fall off. The hook has the advantages of simple structure, low cost, and improved work efficiency, and solves the problems of the difficulty in hanging the signboard and the unstable hanging of the signboard that is easy to fall off. Next, the hook for the signboard of the secondary power air switch proposed in the embodiment of the present application is described in detail.

[0027] Please refer to Figure 1 , Figure 1 The schematic diagram of the electric secondary air switch identification plate hook proposed in the embodiment of the present application is shown. The hook is installed on the air switch, and includes a rectangular fitting portion 3, a rectangular base 1 fixed on the rectangular fitting portion 3, and a hook portion 2 fixed to the lower half of the side of the rectangular base 1. A protrusion 5 is provided on the inner side of the end of the hook portion 2, and the angle between the hook portion 2 and the rectangular base 1 is 15°.

[0028] based on Figure 1 Please refer to Figure 2 , Figure 3 and Figure 4 , Figure 2 The top schematic diagram of the electric secondary air switch identification plate hook proposed in the embodiment of the present application is shown. Figure 3 A side view of the electric secondary air switch identification plate hook proposed in an embodiment of the present application is shown. Figure 4 A front schematic diagram of the electric secondary air switch identification plate hook proposed in an embodiment of the present application is shown.

[0029] The electric secondary air switch identification plate hook proposed in the embodiment of the present application is composed of three parts, namely a rectangular fitting part 3, a rectangular base 1 and a hook part 2. The rectangular fitting part 3 fixes the hook to the body of the air switch and can replace the operating handle of the air switch to hang the retractable identification plate.

[0030] The rectangular base 1 serves as a receiving portion of the hook portion 2 and has an included angle of 15° with the hook portion 2 to ensure that the opening between the hook portion 2 and the rectangular base 1 is reasonable.

[0031] A protrusion 5 is provided on the inner side of the end of the hook portion 2 to quickly hang and take out the sign while preventing the sign from accidentally falling off.

[0032] In addition, the overall size of the power secondary air switch identification plate hook proposed in the embodiment of the present application is not restricted, and the size can be adjusted proportionally according to the actual situation.

[0033] The size of the identification plate hook of the power secondary air switch proposed in the embodiment of the present application is controllable and can be applied to all standard air switches. One air switch corresponds to one identification plate hook, and the function of the identification plate prompt will not be affected by changing the hanging method, which complies with industry standards.

[0034] In addition, the embodiments of the present application also have the advantages of simple structure, low cost, and the ability to improve work efficiency to a certain extent.

[0035] In a possible implementation, the rectangular fitting portion 3 uses double-sided nano-traceless adhesive to fix the hook to the air switch body.

[0036] The fitting part is double-sided nano-traceless adhesive, one side of which is attached to the hook base and the other side is attached to the air switch body. Since the double-sided nano-traceless adhesive has the advantage of strong viscosity, the double-sided nano-traceless adhesive is used as the rectangular fitting part 3 so that the hook and the air switch body can fit tightly and are not easy to fall off.

[0037] In a possible implementation, a double-sided nano-traceless adhesive film 4 is provided on the inner side of the end of the double-sided nano-traceless adhesive fixing the air switch body.

[0038] Before the identification plate hook is pasted, the secondary air switch veneer of the double-sided nano-traceless adhesive is pasted with a double-sided nano-traceless adhesive film 4 for protecting the veneer.

[0039] The protrusion 5 is a spherical protrusion or a mushroom-shaped protrusion.

[0040] The spherical protrusion or the mushroom-shaped protrusion can prevent the sign hung on the sign hook from falling off easily, making it more secure and stable.

[0041] In a possible implementation manner, the hook portion 2 and the rectangular base 1 are fixed in an integrally formed manner.

[0042] In a possible implementation manner, the hook portion 2 is in a hook shape.

[0043] In a possible implementation manner, the hook portion 2 and the rectangular base 1 are made of the same material.

[0044] based on Figure 5 , Figure 5 A schematic diagram of the installation of the electric secondary air switch identification plate hook proposed in the embodiment of the present application is shown. The electric secondary air switch identification plate hook proposed in the embodiment of the present application is further explained below.

[0045] The hook is composed of a fitting part, a base, and a hook, wherein the fitting part is a double-sided nano-traceless adhesive, one side of which is attached to the hook base, and the other side is used to attach to the secondary air switch 6; there is a spherical protrusion on the inner side of the end of the hook, such as Figure 3As shown. The spherical protrusion can play a certain role in preventing it from falling off;

[0046] Before the hook is pasted, the secondary air switch 6 of the double-sided nano-traceless adhesive is pasted with a double-sided nano-traceless adhesive film to protect the veneer. The base, hook, and spherical protrusion are integrally formed of the same transparent material, which is beneficial to improve the overall strength of the hook and is easy to produce.

[0047] When in use, the hook is directly attached to a suitable position of the air switch body (without affecting the normal opening and closing of the secondary air switch operating handle 7).

[0048] In summary, the present application discloses a hook for a signboard of a secondary power air switch, which includes a rectangular fitting portion 3, a rectangular base 1 fixed on the rectangular fitting portion 3, and a hook portion 2 fixed to the lower half of the side of the rectangular base 1. A protrusion is provided on the inner side of the end of the hook portion 2, and the angle between the hook portion 2 and the rectangular base 1 is 15°. The hook is installed on the air switch body to replace the air switch operating handle to hang a retractable signboard. The hook and the base have a reasonable opening, and there is a spherical protrusion on the inner side of the end of the hook portion 2, which can realize the quick hanging of the signboard while preventing the signboard from falling off accidentally. The fitting portion allows the hook to fit tightly with the air switch body and is not easy to fall off. The hook has the advantages of simple structure, low cost, and improved work efficiency, and solves the problems of difficult signboard hanging process and unstable signboard hanging and easy to fall off.
