[0025] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings.

[0026] Example 1: As shown in the attached document Figure 1 To be continued Figure 3 As shown, a unit operation warning device suitable for a single warned device includes a housing 1 and a mounting component 2.

[0027] The housing 1 includes a base plate 3, a first side plate 4, and a second side plate 5. The housing 1 is at least partially transparent. The base plate 3, first side plate 4, and second side plate 5 are all approximately rectangular, thus each has a first side edge and a second side edge. The first side edge of the first side plate 4 connects to the first side edge of the base plate 3, and the first side edge of the second side plate 5 connects to the second side edge of the base plate 3. The first side plate 4 and the second side plate 5 are located on the same side of the base plate 3, and the surface direction of both the first side plate 4 and the second side plate 5 is not parallel to the surface direction of the base plate 3. The surface direction of the first side plate 4 forms an acute angle with the surface direction of the base plate 3; the surface direction of the second side plate 5 also forms an acute angle with the surface direction of the base plate 3. The first side plate 4 and the base plate 3, as well as the second side plate 5 and the base plate 3, are connected by an arc-shaped transition structure. A space for accommodating the warning device is formed between the first side plate 4, the second side plate 5, and the base plate 3.

[0028] Mounting component 2 includes a first mounting plate 6 and a second mounting plate 7. One edge of the first mounting plate 6 is connected to the second edge of the first side plate 4, and one edge of the second mounting plate 7 is connected to the second edge of the second side plate 5. The surface direction of the first mounting plate 6 is not parallel to the surface direction of the first side plate 4, and the surface direction of the second mounting plate 7 is not parallel to the surface direction of the second side plate 5. The surface directions of both the first mounting plate 6 and the second mounting plate 7 are parallel to the surface direction of the base plate 3. A first magnet 8 is provided on the first mounting plate 6, and a second magnet 9 is provided on the second mounting plate 7. The base plate 3 and the first mounting plate 6 are located on opposite sides of the first side plate 4, and the base plate 3 and the second mounting plate 7 are located on opposite sides of the second side plate 5. The first side plate 4 and the first mounting plate 6, and the second side plate 5 and the second mounting plate 7 are also connected by an arc-shaped transition structure. The arc-shaped structure between the first side plate 4 and the first mounting plate 6 has different connection radii on both sides of the first side plate 4, and the arc-shaped structure between the second side plate 5 and the second mounting plate 7 has different connection radii on both sides of the second side plate 5. The thickness of the first mounting plate 6 and the second mounting plate 7 are both greater than the thickness of the base plate 3, the first side plate 4, and the second side plate 5.

[0029] A first mounting groove can be formed on the first mounting plate 6, and a second mounting groove can be formed on the second mounting plate 7, so that the first magnet 8 is embedded in the first mounting groove and the second magnet is embedded in the second mounting groove. The opening direction of the first mounting groove and the opening direction of the second mounting groove both face the direction of the base plate 3. In this embodiment, the bottom surface of the first mounting groove and the bottom surface of the second mounting groove are both circular, and the first magnet 8 and the second magnet 9 are both cylindrical magnets. After the first magnet 8 and the second magnet 9 are respectively embedded in the first mounting groove and the second mounting groove, the surface of the first magnet 8 is flush with the opening of the first mounting groove, and the surface of the second magnet 9 is flush with the opening of the second mounting groove. The first magnet 8 and the second magnet 9 are both neodymium iron boron magnets.

[0030] The aforementioned unit operation warning device, including the housing 1 and the mounting component 2, is integrally molded from a non-conductive plastic with a certain degree of elasticity, making the entire device transparent. In addition, the base plate 3 of the housing 1 has a silkscreen printing position for printing warning messages (such as "Equipment in operation" or "Do not close the switch, people are working").

[0031] This work warning device is installed outside the individual device being warned during operation. On the one hand, it expands the scope of application, not only applicable to air switches, but also to other devices on a flat panel, such as buttons with indicator lights. For devices that can be clamped, it can be installed using clips, while for those that cannot be clamped or whose panel cannot be opened, it can be installed using magnetic adsorption, making it easier to use. On the other hand, its transparent material allows operators to easily observe the status of the device being warned (the open / closed state of the air switch or the on / off state of the button with an indicator light, etc.), thus facilitating construction.

[0032] Example 2: As shown in the attached document Figure 4 To be continued Figure 6 As shown, a multi-position work warning device applicable to at least two warned devices is disclosed. Its main difference from Embodiment 1 is the increased width of the device. Furthermore, both the first and second mounting slots are rectangular slots, with their length direction aligned with the width direction of the device. The first magnet 8 and the second magnet 9 are also rectangular magnets, and their surfaces, after being embedded in the first and second mounting slots respectively, are slightly lower than the surfaces of the first mounting plate 6 and the second mounting plate 7.

[0033] The work warning device of this utility model can cover all working scenarios such as secondary screens, terminal boxes, and distribution boxes, and is compatible with multiple brands of air switches, meeting the principles of safety, practicality, and controllability.

[0034] The above embodiments are only for illustrating the technical concept and features of this utility model, and are intended to enable those skilled in the art to understand the content of this utility model and implement it accordingly. They should not be construed as limiting the scope of protection of this utility model. All equivalent changes or modifications made in accordance with the spirit and essence of this utility model should be included within the scope of protection of this utility model.
