[0002] Inverter remote controllers can be divided into digital and analog types according to different communication signals, and wired and wireless types according to different communication media. Different communication protocols also have corresponding products. Inverter remote controllers are intelligent instruments that realize remote operation of inverters. They remotely control the start, stop, acceleration, deceleration, forward and reverse rotation of the inverter through the RS485 network, and display the operating status information such as the operating frequency and speed of the inverter in real time. They are generally installed in a box for use.

[0003] The existing frequency converter is generally fixed in the box by bolt installation. Although it can achieve the purpose of limiting the installation of the frequency converter, in actual use, when the frequency converter needs to be replaced or repaired, it needs to be disassembled. The existing installation method is time-consuming during disassembly and assembly, and the frequency converter cannot be quickly disassembled and assembled. Therefore, there is an urgent need to improve the technology of the frequency converter structure that is easy to install to improve this equipment. Utility Model Content

[0026] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention; it is obvious that the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention.

[0027] Example:

[0028] See also Figure 1-5 A variable frequency controller that is easy to install includes a variable frequency controller 1. A box body 2 is provided on the outside of the variable frequency controller 1. The box body 2 is fixed with a mounting seat 3 by bolts corresponding to the position of the variable frequency controller 1.

[0029] A mounting block 4 is fixed to the position of the frequency conversion controller 1 corresponding to the mounting base 3. A mounting groove 5 is formed at one end of the mounting base 3 close to the mounting block 4. An opening groove 6 is formed inside the mounting block 4. Two symmetrical clamping blocks 7 are slidably connected to the inner wall of the opening groove 6. A spring 8 is fixedly connected between the two clamping blocks 7.

[0030] The mounting block 4 is provided with pressure rod grooves 9 on both lateral sides near the opening groove 6, and a pressure rod 10 is slidably connected inside the pressure rod groove 9. One end of the pressure rod 10 near the opening groove 6 is connected to a transmission frame 11, and two symmetrical grooves 12 are provided in the transmission frame 11. The position of the card block 7 corresponding to the groove 12 is connected to a transmission rod 13, and the position of the mounting seat 3 corresponding to the card block 7 is provided with a card slot 14.

[0031] When installing the frequency converter 1, the frequency converter 1 can drive the mounting block 4 to be directly inserted into the mounting seat 3, so that one end of the curved surface of the card block 7 is squeezed, thereby overcoming the elastic force of the spring 8 and retracting into the open groove 6. When the card block 7 is aligned with the card slot 14, the restoring elastic force generated by the spring 8 drives the card block 7 to be inserted into the card slot 14, and the installation of the frequency converter 1 can be completed. When disassembly is required, the pressure rods 10 on both sides of the mounting block 4 can be squeezed at the same time, and the card block 7 can be driven out of the card slot 14 through the transmission mechanism of the figure-eight transmission frame 11 and the transmission rod 13, thereby completing the disassembly operation of the frequency converter 1, thereby achieving the purpose of quickly disassembling and assembling the frequency converter 1.

[0032] See also Figure 3-5 The end of the block 7 close to the mounting seat 3 is a smooth curved surface, and the height of the curved surface of the block 7 gradually increases from the side away from the mounting groove 5 to the side close to the mounting groove 5. By setting the end of the block 7 close to the mounting seat 3 to a smooth curved surface, when the frequency converter 1 drives the mounting block 4 to be inserted into the mounting seat 3, one end of the curved surface of the block 7 can be against the mounting seat 3. Due to the design of the curved surface of the block 7, the block 7 can be gradually squeezed into the open groove 6 to avoid hindering the movement of the mounting block 4. The cross-sections of the pressure rod groove 9 and the pressure rod 10 are adaptive rectangles, and the pressure rods 10 are symmetrically arranged on both sides of the mounting block 4. By setting the cross-sections of the pressure rod groove 9 and the pressure rod 10 to adaptive rectangles, the pressure rod 10 can only move back and forth laterally in the pressure rod groove 9, avoiding the movement direction of the transmission frame 11 from deviating.

[0033] See also Figure 4-5 The cross-section of the pressure rod 10 is an eight-shaped shape. The two grooves 12 on the transmission frame 11 are respectively located at the two bifurcated parts of the eight-shaped transmission frame 11. The cross-section of the transmission rod 13 is circular, and the corners of the groove 12 are arc-shaped transitions. The sizes of the transmission rod 13 and the groove 12 are consistent. The card groove 14 is connected to the mounting groove 5, and the contact between the card groove 14 and the card block 7 is provided with a polishing layer.

[0034] By squeezing the two pressure rods 10 at the same time, the pressure rod 10 can drive the transmission frame 11 to move toward the open groove 6. The transmission rod 13 is located in the groove 12 on the transmission frame 11. The cross-section of the transmission frame 11 is an eight-shaped. When the transmission frame 11 moves, the position of the groove 12 thereon can be changed, while the transmission rod 13 can only move up and down. Therefore, when the transmission frame 11 moves, the transmission rod 13 can be driven to move longitudinally, thereby driving the card block 7 to move out of the card slot 14.

[0035] Working principle: When using this variable frequency controller that is easy to install, first, when installing the variable frequency controller 1, the variable frequency controller 1 can drive the mounting block 4 to be directly inserted into the mounting seat 3, so that one end of the curved surface of the clamping block 7 is squeezed, thereby overcoming the elastic force of the spring 8 and shrinking into the open groove 6. When the clamping block 7 is aligned with the clamping slot 14, the restoring elastic force generated by the spring 8 drives the clamping block 7 to be inserted into the clamping slot 14, and the installation of the variable frequency controller 1 is completed;

[0036] When disassembly is required, the pressure rods 10 on both sides of the mounting block 4 can be squeezed at the same time, and the pressure rods 10 drive the eight-shaped transmission frame 11 to move. The transmission rod 13 is located in the groove 12 on the transmission frame 11, and the cross-section of the transmission frame 11 is eight-shaped. When the transmission frame 11 moves, the position of the groove 12 on it can be changed, and the transmission rod 13 can only move up and down. Therefore, when the transmission frame 11 moves, the transmission rod 13 can be driven to move longitudinally, thereby driving the card block 7 to move out of the card slot 14, and the disassembly operation of the frequency converter 1 can be completed, thereby achieving the purpose of quick disassembly and assembly of the frequency converter 1, simple operation, and convenient use.

[0037] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
