[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Please see Figures 1 to 4 This utility model provides a technical solution: an inverter that is easy to maintain, including an inverter housing 1 and cover plates 2 installed at both ends of the inverter housing 1. Four rectangularly distributed pins 3 are fixedly connected to the side wall of the cover plate 2. The side wall of the inverter housing 1 has a socket 101. The end of the pin 3 is inserted into the socket 101. The pin 3 is a cylindrical pin structure and the socket 101 is a round hole structure. A support block 6 is fixedly connected to the side wall of the inverter housing 1. An elastic telescopic component 5 is fixedly connected to the top of the support block 6. A stop block 4 is fixedly connected to the upper end of the elastic telescopic component 5. The end of the stop block 4 abuts against the cover plate 2.

[0023] When it is necessary to separate the cover plate 2 from the inverter housing 1, pull the traction bar 8 upward to move the stop block 4 upward, and then pull the cover plate 2 in a horizontal direction away from the inverter housing 1 to separate the cover plate 2 from the inverter housing 1, thus achieving the purpose of disassembly. This disassembly method is faster and more convenient, saves time, and significantly improves the efficiency of maintenance and repair.

[0024] When the traction bar 8 is released, the elastic telescopic component 5 will pull the stop block 4 down, causing the stop block 4 to move to the front side of the cover plate 2, thereby limiting the cover plate 2 and preventing the cover plate 2 from separating from the inverter housing 1, thus achieving the purpose of quick installation and fixing.

[0025] Furthermore, the elastic telescopic component 5 includes a fixed sleeve 501 fixed to the top of the support block 6 and a limiting rod 503 movably inserted inside the fixed sleeve 501. The upper end of the limiting rod 503 is fixedly connected to the stop block 4, and a spring 502 is fixedly connected between the bottom end of the limiting rod 503 and the inner bottom wall of the fixed sleeve 501.

[0026] The limiting rod 503 has a round rod-shaped structure, and the fixed sleeve 501 has a circular cavity inside to accommodate the insertion of the limiting rod 503.

[0027] When the traction bar 8 is released, the spring 502 will release its elastic force, pulling the limit rod 503 down. The limit rod 503 will drive the stop block 4 down, causing the stop block 4 to move to one side of the cover plate 2, thereby limiting the cover plate 2 and preventing the cover plate 2 from separating from the inverter housing 1, thus achieving the purpose of quick installation and fixing.

[0028] To facilitate simultaneous traction of the two stops 4, this application also includes a traction bar 8 located above the inverter housing 1 and plugs 9 fixed at both ends of the traction bar 8. A slot 401 is provided at the top of the stop 4, and the lower end of the plug 9 is inserted into the slot 401. A screw hole 402 is provided on the side wall of the slot 401, and a bolt 10 is threaded into the screw hole 402. The end of the bolt 10 abuts against the stop 4.

[0029] When it is necessary to connect the traction bar 8 to the two stops 4, insert the plug 9 at the end of the traction bar 8 into the slot 401, and then screw the bolt 10 into the screw hole 402 so that the threaded end of the bolt 10 abuts against the plug 9 to achieve locking, thus achieving the purpose of installing the traction bar 8.

[0030] A bottom strip 7 is fixedly connected to the side wall of the inverter housing 1 near the bottom. The side wall of the bottom strip 7 has an opening 701. By setting fasteners inside the opening 701, the bottom strip 7 is fixedly installed on other equipment, thus achieving the purpose of installing the inverter.
