[0036] The following will further describe the present application in detail Figures 1-4 in conjunction with the accompanying drawings.

[0037] Please refer to Figures 1-4 , an aluminum row connection structure for a frequency converter, which includes a main body module 100 and a connection module 200. The main body module 100 includes a mounting plate assembly 110, and a frequency converter housing 120 is provided on the mounting plate assembly 110. The connection module 200 is arranged between the frequency converter housing 120 and the mounting plate assembly 110. The connection module 200 includes an aluminum row mounting assembly 210 provided on the mounting plate assembly 110. A housing limiting assembly 220 is arranged between the frequency converter housing 120 and the mounting plate assembly 110, and an opening and closing assembly 230 is provided at the bottom of the frequency converter housing 120.

[0038] Through the setting of the aluminum row mounting assembly 210, it is convenient to install and fix the aluminum row. Through the setting of the housing limiting assembly 220, the frequency converter housing 120 can be installed after the aluminum row is installed and the frequency converter housing 120 can be limited, improving the practicability of this structure. Through the setting of the opening and closing assembly 230, the bottom of the frequency converter housing 120 can be opened and closed, so as to facilitate the installation of the frequency converter housing 120 after the aluminum row is installed.

[0039] The mounting plate assembly 110 includes a mounting plate body 111. Mounting pins 112 are threadedly connected to the four corners of the mounting plate body 111, and all four mounting pins 112 extend to the outside of the mounting plate body 111. The aluminum busbar mounting assembly 210 includes an L-shaped block 211 fixedly connected to one side of the mounting plate body 111. The inner side of the L-shaped block 211 is movably clamped with an aluminum busbar body 212. The aluminum busbar mounting assembly 210 further includes a plurality of first fixing pins 213 that are all threadedly connected to the other side of the mounting plate body 111, and all the plurality of first fixing pins 213 extend into the aluminum busbar body 212. The housing limiting assembly 220 includes a limiting frame 221 fixedly connected to one side of the mounting plate body 111 and located outside the aluminum busbar body 212. An n-shaped frame 222 is slidably clamped inside the limiting frame 221. One side of the n-shaped frame 222 is fixedly connected to the frequency converter housing 120. A plurality of second fixing pins 223 are threadedly connected to the other side of the frequency converter housing 120, and all the plurality of second fixing pins 223 extend into the n-shaped frame 222. The main body module 100 further includes a notch 130 opened at the bottom of the frequency converter housing 120.

[0040] By sliding the aluminum busbar body 212 into the inner side of the L-shaped block 211, and then threadedly connecting the first fixing pins 213 into the mounting plate body 111 and extending them into the aluminum busbar body 212, the aluminum busbar body 212 can be fixed. Then, the n-shaped frame 222 is slidably connected into the limiting frame 221, enabling the aluminum busbar body 212 to move to the inner side of the frequency converter housing 120 through the notch 130. Then, the second fixing pins 223 are threadedly connected into the mounting plate body 111 and extend into the n-shaped frame 222, thereby being able to fix the n-shaped frame 222, and further realizing the fixation of the frequency converter housing 120, making the overall structure able to limit and install the frequency converter housing 120 after installing the aluminum busbar, making the overall installation stable and improving the practicability.

[0041] The opening and closing assembly 230 includes two hinges 231 both arranged at the bottom of the frequency converter housing 120.

[0042] The iron opening and closing plate 232 is rotated by the hinge 231 to be opened, so that the magnet block 234 can be separated from the iron opening and closing plate 232. When the iron opening and closing plate 232 needs to be closed, the iron opening and closing plate 232 is rotated in the reverse direction by the hinge 231 so that the iron opening and closing plate 232 can be magnetically connected to the magnet block 234 again.

[0043] The implementation principle of the embodiment of this application is as follows: When the aluminum row body 212 needs to be installed, first slide and snap the aluminum row body 212 inside the L-shaped block 211, and then thread the first fixing pin 213 into the inside of the mounting plate body 111 and extend it into the inside of the aluminum row body 212, so as to be able to fix the aluminum row body 212. Then, rotate and open the iron opening and closing plate 232 through the hinge 231, so that the iron opening and closing plate 232 can be separated from the magnetic block 234, thereby avoiding the iron opening and closing plate 232 from blocking the notch 130. Then, move the frequency converter housing 120 to drive the n-shaped frame 222 to slide and snap inside the limit frame 221, so that the aluminum row body 212 can enter the inside of the frequency converter housing 120 through the notch 130, thereby facilitating the limit installation of the frequency converter housing 120. Then, thread the second fixing pin 223 into the inside of the mounting plate body 111 and extend it into the inside of the n-shaped frame 222, and then it can fix the n-shaped frame 222, thus realizing the fixation of the frequency converter housing 120. Then, rotate the iron opening and closing plate 232 in the reverse direction through the hinge 231 to close it, so that the iron opening and closing plate 232 can be magnetically connected to the magnetic block 234 again, thereby completing the installation of the aluminum row body 212. Through the setting of the mounting pin 112, it is convenient to mount the mounting plate body 111 on the frequency converter.

[0044] The above are all the preferred embodiments of this application, and the protection scope of this application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the protection scope of this application.
