It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0021] Example One

[0022] An inverter cover clamping assembly 100, such as Figures 1-2 As shown, it includes an upper cover slot 1 installed on the upper cover 6 of the external inverter 200, a snap base 2 installed on the bottom frame 7 of the inverter 200, a bottom snap 3 and a flat round head screw 4 installed on the snap base 2, the snap base 2 includes a connecting bottom surface 21 and a mounting column 22, the mounting column 22 is provided with a mounting through hole (not shown in the figure), one end of the bottom snap 3 is a snap head 31 for snapping into the upper cover slot 1, and the other end of the bottom snap 3 is a threaded hole column 32, the threaded hole column 32 is installed in alignment with the mounting through hole, and the flat round head screw 4 passes through the mounting through hole and is locked into the threaded hole column 32.

[0023] As described above, the inverter upper cover clamping assembly 100 of this embodiment is installed on the external inverter 200. Specifically, the upper cover clamping slot 1 is installed on the upper cover 6 of the inverter 200, and the clamping base 2 is installed on the bottom frame 7 of the inverter 200. The clamping base 2 includes a connecting bottom surface 21 for installation on the bottom frame 7, and a mounting column 22 for installing the bottom clamp 3 and the flat round head screw 4. The mounting column 22 is provided with a mounting through hole.

[0024] The bottom clip 3 includes a clip head 31 and a threaded post 32. The threaded post 32 has a threaded hole aligned with the mounting hole. A flat-head screw 4 is inserted through the other end of the mounting hole and securely installed in the threaded post 32. The clip head 31 is used to snap into the upper cover slot 1. Therefore, the inverter upper cover snap assembly 100 of this embodiment allows the upper cover 6 to be conveniently snapped onto the clip head 31 of the bottom frame 7, thereby firmly attaching the upper cover 6 to the ground frame and enhancing the overall integrity and aesthetics of the inverter 200.

[0025] Example Two

[0026] Also includes a spring 5, such as Figures 1-2 As shown, the spring 5 is installed on the outer periphery of the threaded hole column 32, one end of the spring 5 abuts against the buckle head 31, and the other end of the spring 5 abuts against the outer edge of the mounting through hole.

[0027] As described above, the spring 5 is sleeved onto the outer periphery of the threaded post 32. Therefore, one end of the spring 5 abuts the snap head 31 connected to the threaded post 32, while the other end of the spring 5 abuts the outer edge of the mounting hole. It is understood that after the truss head screw 4 is securely mounted on the threaded post 32, there is a margin in the mounting hole, allowing the truss head screw 4 to move axially. With the spring 5 sleeved onto the outer periphery of the threaded post 32, the force of the spring 5 causes the threaded post 32 to move axially, thereby also allowing the snap head 31 to move axially along the threaded post 32. In other words, the snap head 31 is retractably engaged with the upper cover slot 1. This makes the closing of the upper cover 6 on the bottom frame 7 more convenient and secure.

[0028] Example Three

[0029] The top of the mounting post 22 is provided with a positioning pin 23. Figures 1-2 As shown, the upper cover slot 1 is provided with a positioning hole 11 corresponding to the positioning pin 23 .

[0030] As mentioned above, the positioning pin 23 and the positioning hole 11 are used for mutual positioning, so that the engagement between the buckle head 31 and the upper cover slot 1 can be made more accurate.

[0031] Example Four

[0033] As mentioned above, the connecting bottom surface 21 is tightly mounted on the top wall 71 of the bottom frame 7 of the external inverter 200, and the two mounting holes 24 on the connecting bottom surface 21 are used for mounting on the top wall 71. It can be understood that the connecting bottom surface 21 can be mounted on the top wall 71 of the bottom frame 7 by passing bolts through the two mounting holes 24, so that the installation of the snap base 2 on the bottom frame 7 is more stable.

[0034] Example Five

[0035] like Figures 1-2 As shown, the mounting post 22 is provided with a receiving cavity 25 for receiving the bottom buckle 3 .

[0036] The accommodating cavity 25 on the mounting column 22 is used for accommodating and mounting the bottom buckle 3. It can be understood that, in order to be clamped on the upper cover slot 1, part of the buckle head 31 is exposed from the accommodating cavity 25.

[0037] Example Six

[0038] As shown in Figures 1-3 , the upper cover slot 1 is tightly mounted on the inner side wall of the upper cover 6 of the inverter 200. The upper cover slot 1 is provided with a buckle hole 12 corresponding to the buckle head 31. Two connecting holes 13 for tightly mounting on the inner side wall are arranged on both sides of the buckle hole 12.

[0039] The bottom edge of the buckle hole 12 is provided with an arc-shaped chamfer (not shown in the figure).

[0040] The buckle head 31 is provided with a buckle chamfer 33 corresponding to the arc-shaped chamfer.

[0041] The buckle hole 12 is used for clamping the buckle head 31, so that the upper cover 6 and the bottom frame 7 are stably mounted. The connecting hole 13 is used for mounting the upper cover slot 1 on the inner side wall of the externally connected upper cover 6 by bolts. The buckle chamfer 33 of the buckle head 31 is pushed to move backward along the axial direction of the threaded hole column 32 to overcome the force of the spring 5 due to the downward pressure force of the arc-shaped chamfer of the buckle hole 12. When the buckle head 31 is clamped into the buckle hole 12, the buckle head 31 is completely clamped into the buckle hole 12 due to the force of the spring 5, so that the upper cover 6 can be stably mounted on the bottom frame 7.

[0042] Example Seven

[0043] An inverter 200, as shown in Figures 1-5 , comprises the inverter upper cover 6 clamping assembly 100 of any one of embodiments one to seven.
