Description

Technical Field

[0001] The utility model relates to the technical field of frequency converter clamping devices, in particular to an adjustable frequency converter clamping structure. Background Technique

[0002] A frequency converter is a power control device that applies frequency conversion technology and microelectronics technology to control an AC motor by changing the frequency of the motor's working power supply. The frequency converter mainly consists of a rectifier (AC to DC), a filter, an inverter (DC to AC), a braking unit, a drive unit, a detection unit, a microprocessing unit, etc. The frequency converter adjusts the voltage and frequency of the output power supply by the on-off of the internal IGBT, provides the required power supply voltage according to the actual needs of the motor, and thus achieves the purpose of energy saving and speed regulation. In addition, the frequency converter also has many protection functions, such as overcurrent, overvoltage, overload protection, etc. Existing frequency converters are generally fixed by screws, which are inconvenient to disassemble. When overhauling, the screws need to be removed, and the installation surface is easily damaged during reinstallation. Therefore, a frequency converter clamping structure is needed.

[0003] A patent of Chinese Patent Application CN220570451U discloses a PLC frequency converter clamping structure, including two first mounting plates. Second mounting plates are fixedly provided at the lower ends of one sides of the two first mounting plates. A PLC frequency converter body is arranged between the second mounting plates. Convex blocks are fixed on both sides of the PLC frequency converter body. Threaded rods are arranged on one sides of the two first mounting plates. The two threaded rods are respectively in threaded connection with the convex blocks. In the utility model, the first mounting plate, the second mounting plate, the convex block, the threaded rod, the transmission component, the driving gear, the driven gear, and the rotating shaft are provided. The first mounting plate is fixed on the wall surface by screws. The PLC frequency converter body is placed between the two second mounting plates. One end of the threaded rod is inserted into the convex block. The driven gear rotates to drive the driving gear to rotate. Then one threaded rod rotates, and the transmission component makes the two threaded rods rotate simultaneously. The threaded rod rotates to drive the PLC frequency converter body to gradually move until it fits the first mounting plate, completing the installation.

[0004] However, the existing clamping structure is inconvenient to adjust during use to adapt to the installation of frequency converter bodies of different sizes, and the structure cannot meet more usage requirements, resulting in insufficient practicability of the clamping structure. Therefore, an adjustable frequency converter clamping structure is proposed for the above problems. Content of the Utility Model
