A portable frequency converter

Abstract

This utility model discloses a portable frequency converter, relating to the field of frequency converter technology. It includes a base, with the frequency converter body fixedly connected to the top of the base. Four rollers are provided at the bottom of the base, and four through slots are formed inside the base. Each of the four through slots contains a support column, the bottom of which is fixedly connected to the top of the corresponding roller. Protective support components are provided inside each of the four through slots. These protective support covers slide down to the outer surfaces of the support columns and rollers, effectively preventing dust and other impurities from entering the rollers and thus extending their service life. Simultaneously, the anti-slip pad at the bottom of the protective support cover contacts the ground, assisting the rollers in supporting and fixing the base, thereby improving the stability of the base.

Description

Technical Field

[0001] The utility model relates to the technical field of frequency converters, in particular to a movable frequency converter. Background Art

[0002] The frequency converter is an electric power control device that uses frequency conversion technology and microelectronics technology to control the AC motor by changing the frequency of the motor's working power supply. Some existing frequency converters usually have a roller base at the bottom to facilitate the movement of the frequency converter.

[0003] After the existing inverter is moved and placed, the rollers installed on the base support the inverter. Although the traditional rollers have a certain degree of self-locking ability, the stability of the roller support base is still limited. When the inverter is accidentally collided, the base may be easily moved, which may cause damage to the inverter, so that the base cannot be stably placed on the ground, and the stability of the roller base is not strong. Utility Model Content

[0006] Preferably, the protective support assembly includes a protective support cover, the outer surface of the protective support cover is slidably connected to the inner wall of the through groove, the bottom end of the protective support cover is fixedly connected with an anti-slip pad, and the inner wall of the protective support cover is slidably connected to the outer surface of the support column.

[0007] Preferably, a side groove is opened on one side of the protective support cover, and an electric telescopic rod is arranged on the top surface of the inner wall of the through groove, and the output end of the electric telescopic rod is fixedly connected to the top end of the protective support cover.

[0008] Preferably, a limiting groove is provided on one side of the inner wall of the through groove, the inner wall of the limiting groove is slidably connected to a limiting block, and one end of the limiting block is fixedly connected to one end of the protective support cover.

[0009] Preferably, a second thread groove is provided inside the limit block, and there are four protective support assemblies, which are respectively arranged inside the four through grooves.

[0010] Preferably, two first thread grooves are provided on both sides of the base, the inner walls of the four first thread grooves are threadedly connected with adjusting screws, one end of the four adjusting screws are connected to the internal threads of the second thread grooves, and the ends of the four adjusting screws away from the corresponding limit blocks are fixedly connected to a turntable.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] (1) The movable inverter slides down to the outer surface of the support column and the roller through the protective support cover, so that the protective support cover surrounds the outer surface of the support column and the roller, thereby effectively preventing dust and other impurities from entering the interior of the roller, thereby increasing the service life of the roller. At the same time, the anti-slip pad at the bottom of the protective support cover will contact the ground, so that the protective support cover assists the roller to support and fix the base, thereby improving the stability of the base.

[0013] (2) The movable frequency converter is operated by a worker who rotates the turntable, which then drives the adjusting screw to rotate, and then causes the adjusting screw to disengage from the second thread groove, thereby causing the limit block to disengage, thereby causing the limit block, the support column and the roller to disengage at the same time. Then, the roller, the support column and the limit block can be pulled out from the through groove, thereby allowing the roller to be disassembled. The disassembly and assembly method is relatively simple, and a single roller can be easily replaced when it is damaged. BRIEF DESCRIPTION OF THE DRAWINGS
