[0019] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4As shown, a switching power supply protection device includes a mounting plate 2, which is fixedly installed on the front end of the switching power supply body 1. An adjustment assembly 3 is rotatably mounted on the mounting plate 2. The adjustment assembly 3 consists of a threaded rod 7, a handle 8, and an anti-detachment plate 9. The handle 8 and the anti-detachment plate 9 are respectively fixedly installed at the upper and lower ends of the threaded rod 7. A first protection assembly 4 is mounted on the threaded rod 7. The first protection assembly 4 consists of a protective housing 10, an internal threaded cylinder 11, and a first arc-shaped rubber sealing gasket 14. The internal threaded cylinder 11 is fixedly installed on the upper side wall of the protective housing 10. There are several first arc-shaped rubber sealing gaskets 14, all of which are fixedly installed on the front side wall of the protective housing 10. A second protection assembly 5 is fixedly installed on the switching power supply body 1. The second protection assembly 5 consists of a protective plate 15 and a second arc-shaped rubber sealing gasket 17. There are several second arc-shaped rubber sealing gaskets 17, all of which are fixedly installed on the second arc-shaped rubber sealing gasket 17. A terminal block 6 is fixedly installed on the switching power supply body 1. A wire is connected to the terminal block 6 on the switching power supply body 1. After connection, the wire can be placed inside the second arc-shaped rubber sealing gasket 17 on the second protection component 5. Then, the adjusting component 3 can be rotated horizontally on the mounting plate 2, causing the first protection component 4 to move downwards, so that the first arc-shaped rubber sealing gasket 14 presses on the wire. At this time, the wire will be clamped and fixed by the first protection component 4 and the second protection component 5. At the same time, the first protection component 4 and the second protection component 5 also protect the terminal 6. Finally, by setting the mounting plate 2 and the second protection component 5 on the main body 1 of the switching power supply, rotating and installing the adjusting component 3 on the mounting plate 2, and setting the first protection component 4 on the adjusting component 3, the first protection component 4 and the second protection component 5 cooperate to protect the terminal 6 and clamp and fix the wire installed on the terminal 6, thereby preventing the terminal 6 from being exposed, thus reducing the risk of electric shock. It can also prevent the terminal 6 from being damaged by collision and prevent the wire installed on the terminal 6 from detaching from the terminal 6 when pulled.

[0020] Furthermore, the mounting plate 2 has a hole, and the mounting plate 2 is located above the terminal 6. The threaded rod 7 on the adjusting assembly 3 is rotatably installed in the hole on the mounting plate 2. The handle 8 is located above the mounting plate 2, and the anti-detachment plate 9 is located below the mounting plate 2. The threaded rod 7 can be rotated horizontally in the hole on the mounting plate 2 through the handle 8. The first protective assembly 4 can be raised and lowered by rotating the threaded rod 7 in the forward or reverse direction.

[0021] Furthermore, a hole is provided on the upper side wall of the protective housing 10, and the internal threaded cylinder 11 is fixedly inserted into the hole on the upper side wall of the protective housing 10.

The internal threaded cylinder 11 and the threaded rod 7 are threadedly connected. The protective housing 10 is blocked by the switching power supply body 1, so when the threaded rod 7 rotates, the first protection component 4 will not rotate with the threaded rod 7. As a result, the first protection component 4 will move up or down with the rotation of the threaded rod 7.

[0022] Furthermore, the protection plate 15 on the second protection component 5 is fixedly installed on the front side of the terminal block 6. The upper end of the protection plate 15 is provided with several second arc-shaped grooves 16. The second arc-shaped rubber sealing gasket 17 is fixedly installed in the second arc-shaped grooves 16.
