[0002] Variable frequency motor is one of many motors. It has the function of changing the output frequency. Therefore, many industries use variable frequency motors as output sources. Due to the application scenarios, variable frequency motors require additional mounting structures for installation.

[0003] In this regard, China's patent application number: CN202221458368.9 discloses a variable frequency motor that is easy to install and fix, including a mounting frame, a base fixedly connected to the bottom of the mounting frame, a control block movably connected to the middle of the top of the base, a bottom groove is set up inside the base, two support rods are fixedly connected to the side wall of the bottom of the bottom groove, and a linkage rod is rotatably connected to the top of the support rod. One end of the two linkage rods is fixedly connected to a movable support plate, and the end of the linkage rod close to the control block is rotatably connected to a connecting rod, and one side of the movable support plate is fixedly connected to a clamping arc plate. The utility model has the following advantages: the motor is placed in the mounting frame, and the control block can be pressed into the bottom groove by the weight of the motor itself. Through transmission, the movable support plate pushes out the clamping arc plate, and finally the clamping arc plate is tightly clamped on the side walls of the motor on both sides to achieve preliminary connection to the motor, and then the cover is closed, and the pressing plate is pressed on the motor. Through the top force spring, the pressure of the pressing plate can be increased, thereby further improving the stability of the motor after connection, and convenient disassembly and assembly.

[0004] The variable frequency motor is fixed by the cooperation of the clamping arc plate and the pressing plate, but the pressing plate is driven to fit the motor through the top force spring. When the motor vibrates, the pressing plate cannot effectively fix the motor, which will cause the clamping arc plate to fail, thereby affecting the installation of the motor and the user experience.

[0005] Therefore, in order to solve the above problems, a bottom fixing structure of a variable frequency motor is proposed. Utility Model Content
