[0038] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0039] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0040] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0041] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0042] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0043] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0044] like Figures 1-3 As shown, this embodiment provides a protective device 100, including a product body 10. The product body 10 is provided with a display device or adjustment device, such as a potentiometer, indicator light, display screen, switch, etc. Because most of these devices are fragile and cannot withstand too much impact, and the product body 10 may be used in a relatively harsh environment, the devices on the product body 10 are easily damaged by other objects.

[0045] To address the aforementioned issues, the protective device 100 also includes a protective cover 20, which is hinged to the product body 10. The protective cover 20 is used to protect the components on the product body 10, preventing them from being struck by other objects and improving the service life of the product body 10.

[0046] During use, the protective cover 20 will flip and close under the action of gravity. The operator needs to open the protective cover 20 with one hand and operate the device on the product body 10 with the other hand, which is inconvenient.

[0047] To solve the above problems, such as Figures 1-7As shown, the product body 10 provided in this embodiment is provided with a connecting groove 11, and a shaft 12 is provided on the side wall of the connecting groove 11. The protective cover 20 includes a protective cover 21 and a connecting part 22 provided on the protective cover 21. The connecting part 22 has an insertion hole 221. The connecting part 22 is disposed in the connecting groove 11, and the shaft 12 is disposed in the insertion hole 221. The protective cover 21 can rotate around the axis of the shaft 12, so that the protective cover 21 can switch between a first position of closing the product body 10 and a second position of opening the product body 10. The shaft 12 is interference-fitted with the insertion hole 221, and / or the connecting part 22 is interference-fitted with the side wall of the connecting groove 11. With the above configuration, the protective cover 21 can overcome its own weight and hover relative to the product body 10, avoiding the protective cover 21 from flipping and closing under the action of gravity. No additional parts are required, the structure is simple, the processing cost is low, and the assembly efficiency is high, so as to facilitate the operation of the components on the product body 10 by the operator and improve the user's operating convenience.

[0048] like Figure 4 As shown, the connecting part 22 has a trapezoidal structure, and the connecting groove 11 has an inverted trapezoidal structure that matches the connecting part 22, so as to improve the stability of the sidewalls of the connecting part 22 and the connecting groove 11 and prevent loosening or falling off.

[0049] Optionally, the connecting part 22 is provided with a first guide slope 223 on the side facing the insertion shaft 12, and / or the insertion shaft 12 is provided with a second guide slope 121 on the side facing the connecting part 22. The connecting part 22 can slide along the first guide slope 223 and the second guide slope 121 so that the insertion shaft 12 can be inserted into the insertion hole 221, which facilitates the quick assembly and disassembly of the protective cover 21 and the product body 10.

[0050] Optionally, the connecting part 22 is provided with a relief groove 222. During the assembly process of the insertion shaft 12 and the insertion hole 221, the connecting part 22 will undergo elastic deformation. By providing the relief groove 222, the connecting part 22 is provided with deformation space.

[0051] Optionally, there are two connecting parts 22, which are disposed at both ends of the top of the protective cover 21 so that the protective cover 21 is subjected to force evenly.

[0052] Optionally, the protective cover 21 is made of plastic. Plastic products are lightweight. The friction generated by the interference fit between the connecting part 22 and the side wall of the connecting groove 11 allows the protective cover 21 to be suspended when flipped. Users can open the protective cover 21 to adjust the components on the product body 10 at a small angle. After adjustment, the protective cover 21 can be flipped to the first position of closing the product body 10 with a small force.

[0053] Optionally, the protective cover 21 is made of a transparent material, allowing the status of the devices on the product body 10 to be observed without opening the protective cover 21, making it convenient to use.

[0054] Optionally, the protective cover 21 is provided with a hand grip groove 211, which provides an operating point for the operator to grip and apply force with their fingers to easily open or close the protective cover 21.

[0055] Optionally, the groove wall of the hand strap groove 211 is provided with a flexible material. The flexible material can reduce direct contact between the hand and the edge of the protective cover 21 and prevent the hand from being scratched by the sharp edge of the protective cover 21.

[0056] like Figure 8 As shown, the connecting part 22 is provided with a rounded corner part 224. The rounded corner part 224 can be interference-fitted with the bottom wall of the connecting groove 11 to form an interference area. The interference area requires a large force to flip the protective cover 21, which can prevent the protective cover 21 from closing due to accidental collisions, vibrations or other factors when the product body 10 is disassembled, repaired or adjusted, thereby avoiding affecting maintenance or user operation.

[0057] like Figure 9 As shown, the protective cover 21 can rotate a preset angle D relative to the product body 10 in the interference area. A larger force is required to flip the protective cover 21 in the interference area, while a smaller force can be used to flip the protective cover 21 in other areas, which is convenient for user operation.

[0058] This embodiment also provides a welding machine, which includes the welding machine and the aforementioned protective device 100. The product body 10 is mounted on the welding machine body, and the protective cover 20 provides protection for the components on the product body 10. In this embodiment, the product body 10 is a display and operation device, which is equipped with a potentiometer, indicator lights, a display screen, a selector switch, etc.

[0059] In other embodiments, the product body 10 can also be a welding mask, electronic product, socket, etc., and the protective cover 20 provides protection for the welding mask, electronic product, socket, etc.
