Description

Technical Field

[0001] This utility model relates to the field of frequency converter equipment technology, and more specifically, to a frequency converter handle. Background Technology

[0002] A frequency converter is a power control device that uses frequency conversion technology and microelectronics to control an AC motor by changing the frequency of the power supply. A frequency converter mainly consists of a rectification unit (AC to DC), a filter, an inverter (DC to AC), a braking unit, a drive unit, a detection unit, a microprocessor unit, and a heat dissipation unit. The frequency converter adjusts the voltage and frequency of the output power supply by switching its internal IGBTs, providing the required power voltage according to the actual needs of the motor, thereby achieving energy saving and speed regulation. In addition, frequency converters have many protection functions, such as overcurrent, overvoltage, and overload protection.

[0003] With the continuous improvement of industrial automation, the size of frequency converters has been greatly reduced. However, manual handling is still quite laborious. Therefore, handles are usually fixed on frequency converters to facilitate manual handling and relocation. Currently, handles are usually directly fixed to the frequency converter. After the frequency converter is moved and installed, the handles will affect the aesthetics of the frequency converter. At the same time, due to the influence of the installation location, the handles may also hinder the installation of the frequency converter. Utility Model Content

[0004] The purpose of this invention is to provide a handle for a frequency converter that can be easily disassembled and installed.

[0005] To achieve the above objectives, the technical solution adopted by this utility model is as follows: A frequency converter handle includes a handle body disposed on the upper part of the frequency converter body. The handle body includes an integral grip portion and two plug-in portions. The two plug-in portions are located at the lower ends of both ends of the grip portion. Slots are provided at both ends of the upper part of the frequency converter body. The plug-in portions are inserted into the corresponding slots. A slot is provided at the lower end of the inner side of the slot. A receiving slot penetrating both sides is provided at the lower part of the plug-in portion. A retaining plate is slidably disposed in the receiving slot. An elastic pusher is slidably installed on the upper part of the plug-in portion. The elastic pusher is elastically connected to the retaining plate, and the elastic pusher pushes the retaining plate into the slot through the elastic force.

[0006] Preferably, the upper outer side of the plug-in part is provided with an opening, and both ends of the bottom of the opening are provided with sliding grooves. The sliding grooves are connected to the receiving grooves, and a slider is movably inserted in the sliding grooves. The lower end of the slider is fixedly connected to the card plate, and a sliding plate is fixedly installed between the upper ends of the two sliders. The elastic pusher is elastically connected to the sliding plate.

[0007] Preferably, the elastic pusher includes a baffle and a plurality of springs. The baffle is fixedly installed on the outside of the opening, and one end of each spring is fixedly installed on the inside of the baffle, while the other end of the spring is fixedly connected to the slide plate.

[0008] Preferably, the slide plate has an arc-shaped groove on the side near the slot.

[0009] Preferably, the handle body is made of aluminum alloy.

[0010] Preferably, the surface of the grip portion is provided with anti-slip stripes.

[0011] Compared with the prior art, the advantages of this utility model are:

[0012] The handle of this inverter is easy to install and remove. When it is necessary to remove the handle body, simply insert your fingers into the arc-shaped slots of the two slide plates and pull the slide plates outward. This will disengage the plates from the slots. Then, by applying upward force, the two plug-in parts of the handle body can be removed from the slots, thus completing the disassembly of the lifting body. This avoids the impact of the handle body on the aesthetics of the inverter and the installation process after the inverter is installed. Attached Figure Description

[0020] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.

[0021] See Figures 1-5 As shown, this utility model provides a handle for a frequency converter, including a handle body 2 disposed on the upper part of the frequency converter body 1. The handle body 1 includes an integral grip portion 22 and two plug-in portions 21. The two plug-in portions 21 are located at the lower ends of both ends of the grip portion 22. Slot openings 11 are provided at both ends of the upper part of the frequency converter body 1. The plug-in portions 21 are inserted into the corresponding slot openings 11. A slot 12 is provided at the lower end of the inner side of the slot opening 11. A receiving slot 24 penetrating both sides is provided at the lower part of the plug-in portion 21. A retaining plate 5 is slidably disposed in the receiving slot 24. An elastic pusher 3 is slidably installed on the upper part of the plug-in portion 21. The elastic pusher 3 is elastically connected to the retaining plate 5, and the elastic pusher 3 pushes the retaining plate 5 into the slot 12 through the elastic force, ensuring the stability of the plug-in portion 21 in the slot opening 11.

[0022] In this embodiment, the upper outer side of the plug-in part 21 is provided with an opening 23, and both ends of the bottom of the opening 23 are provided with sliding grooves 25. The sliding grooves 25 are connected to the receiving grooves 24, and a slider 6 is movably inserted in the sliding grooves 25. The lower end of the slider 6 is fixedly connected to the card plate 5. A sliding plate 4 is fixedly installed between the upper ends of the two sliders 6. The elastic pusher 3 is elastically connected to the sliding plate 4.

[0023] In order to ensure that the card plate 5 can be stably locked in the slot 12, in this embodiment, the elastic pusher 3 includes a baffle 31 and multiple springs 32. The baffle 31 is fixedly installed on the outside of the opening 23, and one end of each spring 32 is fixedly installed on the inside of the baffle 31. The other end of the spring 32 is fixedly connected to the slide plate 4. The springs 32 play an elastic role, which can stably press the card plate 5 into the slot 12.

[0024] Furthermore, to facilitate the sliding of the slide plate 4 by the staff, in this embodiment, an arc-shaped buckle groove 41 is provided on the side of the slide plate 4 near the slot 12.

[0025] In this embodiment, the handle body 2 is made of aluminum alloy, which has high structural strength and light weight, and can withstand a large load.

[0026] Furthermore, to enhance the anti-slip properties of the body 2, in this embodiment, the grip portion 22 has anti-slip stripes on its surface.

[0027] The specific operating steps are as follows: When it is necessary to disassemble the handle body 2, simply insert the fingers of both hands into the arc-shaped buckle slots 41 of the two slide plates 4 respectively, and pull the slide plates 4 outward. At this time, the card plate 5 can be disengaged from the card slot 12. Then, by exerting force upward, the two plug-in parts 21 of the handle body 2 can be removed from the slot opening 11, thereby completing the disassembly of the lifting body 2.
