Description

Technical Field

[0001] This utility model relates to the field of frequency converters, and in particular to a waterproof universal frequency converter. Background Technology

[0002] With the continuous improvement of modern industrial automation, frequency converters, as key devices for controlling motor speed and operation, have been widely used in many industries. For example, in manufacturing, frequency converters are used to control the motors of various production equipment to achieve precise speed regulation and energy-saving operation; in public sectors such as water supply and heating, frequency converters are used to regulate the speed of water pumps and fans to meet the flow and pressure requirements under different operating conditions. This widespread application has led to higher market demands for the performance, reliability, and adaptability of frequency converters. However, traditional general-purpose frequency converters have certain shortcomings in terms of waterproof performance. Many industrial applications involve harsh environmental conditions such as humidity, dust, water splashes, and even immersion, such as food processing workshops, sewage treatment facilities, and outdoor construction machinery. In these environments, moisture can easily enter the inside of the frequency converter, leading to problems such as short circuits on circuit boards and corrosion of components.

[0003] In existing frequency converters, some components are secured to the casing using bolts. However, these bolts are prone to aging and rusting after prolonged use, making disassembly very troublesome and affecting user efficiency. Therefore, we propose a waterproof universal frequency converter to solve this problem. Utility Model Content

[0007] Preferably, a first block is slidably connected to the inner side of the fixed cylinder, and one side of the first block is fixedly connected to one side of the third block. A second block is rotatably connected to the inner side of the first block, and a lever is rotatably connected to the outer side of the second block. One side of the lever is movably abutting against the front side of the fixed cylinder.

[0008] Preferably, a first spring is fixedly connected to the inner wall of one side of the circular groove, and the other end of the first spring is fixedly connected to the front side of the third block, and placement grooves are opened on both sides of the inner wall of the inverter body.

[0009] Preferably, each of the two No. 1 bars has a small block fixedly connected to one side, and the inner wall of one side of the inverter body has a groove adapted to the small block. The outer sides of the two small blocks are slidably connected to the inner side of the corresponding groove, and two No. 2 springs are fixedly connected to the inner wall of one side of the inverter body. The other ends of the two No. 2 springs are fixedly connected to one side of the corresponding No. 2 bar.

[0010] Preferably, the inverter body has multiple interfaces on one side.

[0011] Preferably, multiple mounting blocks are fixedly connected to both sides of the inverter body, and threaded holes are opened on the inner side of each of the mounting blocks.

[0012] In this utility model, a waterproof universal frequency converter is provided. By using a mounting block, the user can easily install the device in a suitable position. The user can connect the device to the interface to enable normal operation. The interface can be equipped with a sealing ring to prevent liquid penetration.

[0013] In this utility model, a waterproof universal frequency converter is made of a heat-dissipating material, which facilitates heat dissipation for the internal equipment. When the user needs to open the casing, they can simply turn the lever to rotate it 90 degrees. This causes the second block to rotate, and the first block drives the third block to move horizontally. Subsequently, the fourth block also begins to move horizontally, causing the connecting rod to rotate and the first bar to move horizontally. At this point, the first bar no longer abuts against the second bar, allowing the user to directly remove the casing, which is very convenient. Furthermore, a sealing gasket is provided at the connection between the casing and the frequency converter body, which improves the overall sealing performance of the device.

[0014] This utility model has a reasonable structural design. Through the cooperation between block 1, block 3 and spring 2, the outer shell can be easily fixed to the device, which allows the user to quickly disassemble it, which is very convenient and further improves the user's work efficiency.
