[0030] See also Figure 2-4 The buckle assembly 2 includes a slide plate 21, which is slidably installed in the slide plate groove 11. The slide plate 21 can slide freely in the slide plate groove 11. A slider 22 is arranged on the outer wall of the slide plate 21. The slider 22 is arranged in a trapezoidal shape. The slider 22 is slidably installed in the slider groove 13. This trapezoidal design allows the slider 22 to slide more smoothly in the slider groove 13, and can also prevent the slider 22 from falling off from the slider groove 13. A support spring 23 is fixedly connected to the outer wall of the slider 22. The outer wall of the support spring 23 is fixedly connected to the inner wall of the slider groove 13. Its function is to provide a continuous, outward thrust for the slider 22, so that the slider 22 and the slide plate 21 are always kept in the appropriate positions in the slide plate groove 11 and the slider groove 13. A buckle 24 is arranged below the slider 22. Its design allows the buckle 24 to move freely in the buckle groove 12 and can be snapped into the limiting groove 33 on the shell 3. The buckle 24 is movably installed in the buckle groove 12 and can be snapped into the limiting groove 33.

[0031] See also Figure 3-5The clip assembly 4 includes a fixing plate 41, which is fixedly mounted on the inner wall of the shell 3. A limit block 42 is arranged above the fixing plate 41. The outer wall of the limit block 42 is a circular surface. The limit block 42 is arranged above the fixing plate 41, and its outer wall is a circular surface. This design allows the limit block 42 to play a role in positioning and aligning in the clip assembly, ensuring that the upper cover 1 and the shell 3 can be accurately aligned during assembly. A clip base 43 is arranged on the inner wall of the upper cover 1. Connecting rods 44 are fixedly connected to the protrusions on both sides of the clip base 43. The outer wall of the connecting rod 44 is movably connected to a right clamping block 45 and a left clamping block 46. The outer walls of the right clamping block 45 and the left clamping block 46 are both provided with a support plate 48. The outer wall of the support plate 48 is fixedly connected to a tension spring 47. The upper end of the tension spring 47 is fixedly connected to the clip base 43. The function of the tension spring 47 is to provide a clamping force so that the right clamping block 45 and the left clamping block 46 can tightly clamp the limit block 42. When assembling the power adapter, the elastic force of the tension spring 47 causes the clamping block to automatically clamp the limit block to ensure the stability of the connection. The left clamping block 46 and the right clamping block 45 are clamped on the outer wall of the limit block 42 and fit with the outer wall of the limit block 42. This design ensures that the upper cover 1 and the shell 3 can be tightly connected together during assembly and are not easy to loosen or fall off.

[0032] Working principle: First, when the operator assembles the power adapter, the upper cover 1 and the shell 3 are aligned up and down, and then the slide plate 21 is moved in the slide plate groove 11. When the slide plate 21 moves, it drives the slider 22 to move together. When the slider 22 moves in the slider groove 13, it drives the buckle 24 set below to move. At this time, the buckle 24 is aligned with the inside of the limiting groove 33 opened in the shell 3 and inserted. After the insertion is completed, the slide plate 21 is released. The slide plate 21 is reset by the elastic force of the support spring 23 on the slider 22. At this time, the buckle 24 is engaged with the internal groove body of the limiting groove 33, and the limiting groove 33 limits the buckle 24 in the vertical direction, thereby limiting the movement of the upper cover and the shell 3 in the vertical direction.

[0033] Secondly, after the buckle assembly 2 is connected, press the upper cover 1 around so that the left clamp block 46 and the right clamp block 45 installed on the inner wall of the upper cover 1 are pressed against the limit block 42. When pressing, since the limit block 42 is a circular surface, when the left clamp block 46 and the right clamp block 45 are squeezed downward through the center point of the limit block 42, the left clamp block 46 and the right clamp block 45 move to both sides to squeeze the tension spring 47. When moving to the bottom of the limit block 42, the inner walls of the left clamp block 46 and the right clamp block 45 are completely in contact with the limit block 42, and the limit block 42 is pressed downward. Due to the supporting force of the over-tension spring 47, the right clamp block 45 and the left clamp block 46 firmly fix the limit block 42, so that the upper cover 1 and the shell 3 are firmly fixed without being affected by a large external force, and the upper cover 1 and the shell 3 are fixed by arranging a plurality of groups of clip assemblies 4, so as to achieve the simultaneous movement limitation of the lateral movement and vertical movement of the upper cover 1 and the shell 3. When the staff needs to disassemble the interior for inspection, they only need to push the slide plate 22 again and then tilt it upward from the end of the slide plate 22 to open it.
