The main body of the inverter is the inverter circuit, and it also includes control, protection, and filtering circuits. An inverter is a DC to AC transformer, which is actually a voltage inversion process with a converter. It is widely used in office equipment, household appliances, or when batteries are needed. Inverters are mainly divided into two categories, one is divided according to the wave string properties, and the other is divided according to the source flow properties. The inverter will generate a lot of heat when in use. In order to increase the service life of the inverter, a fan is needed to dissipate the heat of the inverter. When the fan is installed, it is fixed inside the inverter using a mounting bracket so that the fan can work stably.

[0021] It should be noted that the terms "first", "second", etc. in the specification and claims of the present utility model are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence.

[0022] The terms "including" and "having" and any variations thereof in the specification and claims of the present invention are intended to cover non-exclusive inclusions. For example, a process, method, system, product or apparatus comprising a series of steps or units is not necessarily limited to those steps or units explicitly listed, but may include other steps or units not explicitly listed or inherent to these processes, methods, products or apparatuses.

[0023] like Figure 1-5 An inverter internal fan mounting frame shown includes a mounting plate 1, a power mechanism 5, a holding mechanism 6, a plug-in assembly 7 and a fan 8 are arranged at the rear end of the mounting plate 1, the power mechanism 5 is used to provide power to the holding mechanism 6, and the mounting plate 1 is connected to the fan 8 through the plug-in assembly 7; a circular hole 2 is opened on the front end surface of the mounting plate 1, and a filter screen 3 is fixedly connected to the inside of the circular hole 2, and the filter screen 3 corresponds to the fan 8.

[0024] Specifically, when in use, the mounting plate 1 is fixed inside the inverter, and the fan 8 works to discharge the heat inside the inverter, thereby improving the heat dissipation efficiency of the inverter and being beneficial to increasing the service life of the inverter; when the fan 8 works, the filter 3 can filter the dust in the air, thereby effectively preventing the dust from entering the inside of the inverter; when the fan 8 needs to be removed, the power mechanism 5 is used to provide power to the holding mechanism 6, and the fan 8 can be released under the action of the holding mechanism 6, thereby facilitating the removal of the fan 8; when installing the fan 8, the preliminary installation of the fan 8 can be achieved with the cooperation of the plug-in assembly 7, and then the holding mechanism 6 is pressed, so that the fan 8 can be fixed, making it more convenient to disassemble and assemble the fan 8, which is beneficial to improving the maintenance efficiency of the maintenance workers.

[0025] The plug-in assembly 7 includes a plug-in socket 701 and a plug-in frame 702. The plug-in socket 701 is fixedly connected to the rear end of the mounting plate 1. The plug-in frame 702 is slidably connected inside the plug-in socket 701. The fan 8 is fixedly connected inside the plug-in frame 702. When working, the plug-in frame 702 on the fan 8 is aligned with the plug-in slot of the plug-in socket 701. At this time, it is convenient to install the fan 8 into the plug-in socket 701. With the cooperation of the plug-in socket 701 and the plug-in frame 702, the preliminary installation of the fan 8 can be achieved, which is beneficial for the workers to fix it later.

[0026] The holding mechanism 6 includes a bearing seat 601, a rotating shaft 602, a rotating rod 603 and a pressure plate 604. The bearing seats 601 are fixedly connected to both sides of the rear end of the mounting plate 1. The rotating shaft 602 is rotatably connected inside the bearing seat 601. The end of the rotating shaft 602 close to the fan 8 is fixedly connected to the rotating rod 603, and the end of the rotating rod 603 away from the rotating shaft 602 is fixedly connected to the pressure plate 604. When working, the rotating shaft 602 rotates, which can drive the rotating rod 603 to rotate, and then drive the pressure plate 604 to rotate. When the pressure plate 604 approaches the plug-in frame 702, it is convenient to fix the fan 8. When the pressure plate 604 moves in the direction away from the plug-in frame 702, the fan 8 is released, thereby facilitating the removal of the fan 8.

[0027] The power mechanism 5 includes a threaded rod 501, a handle 502, a movable plate 503, a rack 504 and a gear 505. The threaded rod 501 is rotatably connected to the lower end of the socket 701, and the handle 502 is fixedly connected to the lower end of the threaded rod 501. The movable plate 503 is threadedly connected to the circumferential surface of the threaded rod 501. Racks 504 are fixedly connected to both sides of the upper end of the movable plate 503. The rack 504 is meshed with a gear 505. The gear 505 is fixedly connected to the rotating shaft 602. When working, the handle 502 is rotated. At this time, the movable plate 503 can be driven to move with the cooperation of the threaded rod 501, and then the rack 504 can be driven to move. As the rack 504 moves, the gear 505 can be driven to rotate, and then the rotating shaft 602 can be driven to rotate, so that power can be provided for the holding mechanism 6.

[0028] Both sides of the rear end of the mounting plate 1 are fixedly connected to the limiting grooves 9, the limiting blocks 10 are slidably connected inside the limiting grooves 9, and the limiting blocks 10 are fixedly connected to the rack 504. When working, by setting the limiting grooves 9 and the limiting blocks 10, the movement of the rack 504 can be limited with the cooperation of the limiting grooves 9 and the limiting blocks 10, so that the rack 504 can move smoothly.

[0029] The front end surface of the mounting plate 1 is provided with mounting holes 4, and there are four mounting holes 4, which are evenly distributed at the four corners of the mounting plate 1. During operation, the mounting holes 4 are provided, and the mounting plate 1 can be conveniently fixed inside the inverter under the action of the mounting holes 4.
