[0002] Electronic engineering, also known as "low-voltage technology" or "information technology," can be further subdivided into electrical measurement technology, adjustment technology, and electronic technology. Electronic engineering is a subcategory of electrical engineering and is an engineering discipline oriented towards the field of electronics. Today, its research scope has expanded beyond the field of electronics. The application forms of electronic engineering cover electric equipment and various electric switches that utilize control technology, measurement technology, adjustment technology, computer technology, and even information technology. Modern electronic engineering often needs to process massive amounts of information and data, forcing machines to be connected to external power supplies to ensure power supply.

[0003] Regarding the aforementioned technologies, the inventors believe the following shortcomings exist: Currently, in the field of electronic engineering, the use of numerous high-power-consuming devices is commonplace, and these devices often require external power supplies to provide a stable power supply. However, in practice, we often see external power supplies placed haphazardly without dedicated protective measures, which not only increases the risk of electric shock but also makes the power cords susceptible to damage.

[0021] To facilitate understanding of this utility model, a more comprehensive description will be provided below with reference to the accompanying drawings. The drawings show typical embodiments of this utility model.

[0022] Example 1:

[0023] like Figure 1-4 As shown, an external power supply protection cover of this utility model includes a mounting plate 1. A protection component 2 is provided on the top surface of the mounting plate 1, and a limiting component 3 is provided inside the protection component 2. The protection component 2 includes a protective box 201 provided on the top surface of the mounting plate 1. A box door 202 is installed on the top surface of the protective box 201 via a hinge, and a groove 203 is opened on the surface of the protective box 201. A concave plate 204 is fixed inside the protective box 201, and a bearing 205 is fixedly installed on the inner wall of the concave plate 204. A lead screw 206 is fixedly installed inside the bearing 205, and a nut seat 207 is sleeved on the surface of the lead screw 206. A connecting plate 208 is fixed on the top surface of the nut seat 207, and a threaded post 209 is fixed on the top surface of the connecting plate 208. A limiting nut 210 is sleeved on the surface of the threaded post 209.

[0024] like Figure 1-4 As shown, the surface of the threaded column 209 is movably connected to the limiting plate 211, and a rectangular block 212 is fixed on the bottom surface of the limiting plate 211, and a square groove 213 is opened on the top surface of the concave plate 204.

[0025] like Figure 1-4 As shown, the surface of the nut seat 207 fits against the inner wall of the square groove 213, and the concave plate 204 is fixed to the protective box 201 by bolts.

[0026] like Figure 1-4As shown, the surface of the mounting plate 1 is provided with a threaded hole 214, and the inside of the threaded hole 214 is provided with a limiting bolt 215. The surface of the limiting bolt 215 is provided with a corner block 216, and the inner wall of the protective box 201 is fixed with a square plate 217.

[0027] In practice, the protective component 2 is equipped with a protective box 201 and a concave plate 204 inside, which can protect the external power supply. When it is necessary to limit the external power supply, the lead screw 206 can drive the nut seat 207 and the connecting plate 208 to slide. The connecting plate 208 can drive the threaded column 209 and the limiting plate 211 to slide, so that the limiting plate 211 contacts the surface of the external power supply, thereby limiting the external power supply. By turning the limiting nut 210 and sliding the limiting plate 211, the limiting plate 211 can be separated from the threaded column 209, which makes it convenient to replace the limiting plate 211 with different shapes.

[0028] Example 2:

[0029] like Figure 1-4 As shown, based on Embodiment 1, this utility model provides a technical solution: the limiting component 3 includes a sleeve 301 fixed to the inner wall of the protective box 201, and an annular groove 302 is provided on the side surface of the sleeve 301, a sliding groove 303 is provided on the surface of the sleeve 301, a spring 304 is provided inside the sleeve 301, a protrusion 305 is movably connected inside the sleeve 301, and a sliding post 306 is fixed on the surface of the protrusion 305.

[0030] like Figure 1-4 As shown, the limiting component 3 also includes a U-shaped block 307 fixed inside the protective box 201, and a bearing 308 is fixed on the side surface of the U-shaped block 307. A rotating column 309 is fixed inside the bearing 308, and a connecting cable 310 is fixed on the surface of the rotating column 309. The connecting cable 310 forms a fixed structure with the protruding column 305 by bolts.

[0031] like Figure 1-4 As shown, the surface of the sliding post 306 is in contact with the inner wall of the sliding groove 303, and the side surface of the protruding post 305 is in contact with the inner wall of the spring 304.

[0032] During implementation, when it is necessary to disassemble the protective box 201, the rotating column 309 is rotated, which drives the connecting cable 310. The connecting cable 310 drives the protruding column 305 and the sliding column 306 to slide, thereby separating the protruding column 305 from the corner block 216 and sliding the protective box 201, thus separating the protective box 201 from the mounting plate 1.

[0033] The advantages of this technical solution in practical applications include, but are not limited to, the following:

[0034] 1. The protective component 2 is equipped with a protective box 201 and a recessed plate 204. The protective box 201 and the box door 202 can protect the external power supply. When the operator rotates the lead screw 206, the lead screw 206 can drive the nut seat 207 and the connecting plate 208 to slide. The connecting plate 208 can drive the limit plate 211 to slide, thereby facilitating the limitation of the external power supply.

[0035] 2. By providing a sleeve 301 and a rotating column 309 inside the limiting component 3, when the user rotates the rotating column 309, the rotating column 309 can drive the connecting cable 310 to slide, thereby causing the connecting cable 310 to drive the protruding column 305 to slide, thus separating the protruding column 305 from the corner block 216.

[0036] In this technical solution, the protective component 2 has a protective box 201 and a concave plate 204 inside, which can protect the external power supply. When it is necessary to limit the external power supply, the lead screw 206 can drive the nut seat 207 and the connecting plate 208 to slide. The connecting plate 208 can drive the threaded post 209 and the limiting plate 211 to slide, so that the limiting plate 211 contacts the surface of the external power supply, thereby limiting the external power supply. By turning the limiting nut 210, the limiting plate 211 can be slid and separated from the threaded post 209, which is convenient for replacing the limiting plate 211 of different shapes. When it is necessary to disassemble the protective box 201, the rotating post 309 is rotated. The rotating post 309 drives the connecting cable 310, which drives the protruding post 305 and the sliding post 306 to slide, thereby separating the protruding post 305 from the corner block 216. By sliding the protective box 201, the protective box 201 can be separated from the mounting plate 1.
