[0028] Reference Figure 1 As shown, this utility model provides a technical solution: an easy-to-maintain frequency converter receiving device, including a frequency converter receiver body 1, an operating shell 2 mounted on the surface of the frequency converter receiver body 1, and a disassembly device 3 on the surface of the frequency converter receiver body 1, achieving the effect of convenient maintenance of the frequency converter receiver body 1. This avoids the situation where the frequency converter receiver body 1 is difficult to disassemble and maintain when the operator needs to maintain it, which would make it difficult to maintain the frequency converter receiver body 1 in good operating condition, and thus cause the frequency converter receiver body 1 to malfunction and become inoperable during use, thereby improving the practicality of the device. The operating shell 2 is provided with a protective device 4, which achieves the effect of protecting the display screen on the operating shell 2, avoiding the situation where the display screen on the operating shell 2 is damaged or has a distorted screen due to collision with debris, thus making it difficult for the operator to see the frequency converter received data, thereby improving the practicality of the device.

[0029] The following section will explain the specific design and function of the disassembly device 3 and the protective device 4.

[0030] Reference Figure 2 , Figure 3As shown in this embodiment: the disassembly device 3 includes two short rods 301, which are fixedly connected to the surface of the inverter receiver body 1. A screw plate 304 is fixedly connected to the ends of the two short rods 301 that are far apart from each other. A push plate 302 is fixedly connected to the arc surface of each of the two short rods 301. A limiting rod 305 is slidably inserted into the push plate 302. A circular plate 307 is fixedly connected to one end of the limiting rod 305. A limiting groove 308 is formed on the surface of the operating housing 2. A spring 306 is sleeved on the arc surface of the limiting rod 305. The two ends of the spring 306 are fixedly connected to the push plate 302 and the circular plate 307, respectively. Next, the circular plate 307 is released, and the rebound force of the spring 306 drives the circular plate 307. The circular plate 307 drives the limiting rod 305 to slide within the push plate 302 until the limiting rod 305 is inserted into the limiting groove 308. This achieves a stable connection of the limiting rod 305, preventing shaking caused by external factors from causing the limiting rod 305 to detach from the operating housing 2 and improving the stability of the device. The arc surface of the short rod 301 is rotatably connected to a rotating ring 303. The surface of the rotating ring 303 is fixedly connected to the push plate 302. The surface of the frequency converter receiver body 1 is provided with a recycling groove 309. The limiting rod 305 is pulled out from the limiting groove 308, and then the rotating ring 303 is rotated to drive the push plate 302 to rotate on the arc surface of the short rod 301. The push plate 302 drives the limiting rod 305, and the limiting rod 305 drives the circular plate 307 until the limiting rod 305 is perpendicular to the recycling groove 309. Then the circular plate 307 is pushed, and the circular plate 307 drives the limiting rod 305 to slide within the push plate 302 until the limiting rod 305 is inserted into the recycling groove 309. This achieves the effect of rotating and recycling the limiting rod 305, avoiding the shaking caused during disassembly, which would cause the limiting rod 305 to slide back and forth within the push plate 302, thus preventing... When the operator needs to continuously pull the limit rod 305, a positioning plate 310 is fixedly connected to the surface of the inverter receiver body 1. The size of the limit rod 305 is adapted to the size of the limit groove 308. Rotating the rotating ring 303 drives the push plate 302 to rotate on the arc surface of the short rod 301. The push plate 302 drives the limit rod 305, and the limit rod 305 drives the circular plate 307 until the limit rod 305 touches the positioning plate 310, thus achieving the effect of quickly positioning the limit rod 305. This allows the operator to quickly maintain the inverter receiver body 1, thereby speeding up the operation of the inverter receiver body 1.

[0031] Reference Figure 4 , Figure 5As shown, specifically, the protective device 4 includes a connecting block 41, which is fixedly connected to the surface of the operating housing 2. A connecting rod 42 is fixedly connected inside the connecting block 41, and support plates 43 are fixedly connected to both ends of the connecting rod 42. A rotating rod 44 is fixedly connected to one side of the two support plates 43 that are close to each other. A protective cover 46 is rotatably connected to the arc surface of the rotating rod 44. A fixing hole is opened on the surface of the protective cover 46. A support frame 47 is fixedly connected to one side of the support plate 43. A fixing rod 48 is slidably inserted into the support frame 47. A baffle 49 is fixedly connected to the arc surface of the fixing rod 48. The size of the fixing rod 48 is adapted to the size of the fixing hole on the surface of the protective cover 46. By pulling the fixing rod 48, it slides inside the support frame 47. The baffle 49 is moved until it contacts the support frame 47, thus blocking the fixed rod 48 and preventing it from falling off the support frame 47 due to shaking caused by external factors. This would prevent the fixed rod 48 from being damaged and unusable. The arc surface of the rotating rod 44 is fitted with a torsion spring 45, and the two ends of the torsion spring 45 are fixedly connected to the support plate 43 and the protective cover 46, respectively. When the protective cover 46 is released, the torque of the torsion spring 45 drives the protective cover 46 to rotate on the arc surface of the rotating rod 44 until the protective cover 46 is completely in contact with the operating shell 2, thus achieving the effect of automatically opening the protective cover 46. This reduces the number of operation steps for the operator, increases the work efficiency of the operator, and improves the convenience of the device.

[0032] Working principle: When maintenance is required, the limiting rod 305 is pulled out of the limiting groove 308. Then, the rotating ring 303 is rotated, causing the push plate 302 to rotate on the arc surface of the short rod 301. The push plate 302 drives the limiting rod 305, which in turn drives the circular plate 307 until the limiting rod 305 touches the positioning plate 310. Then, the circular plate 307 is pushed, causing the limiting rod 305 to slide within the push plate 302 until the limiting rod 305 is inserted into the recycling groove 309. When maintenance is complete, the limiting rod 305 is pulled out of the recycling groove 309. Then, the rotating ring 303 is rotated, causing the push plate 302 to rotate on the arc surface of the short rod 301. The push plate 302 drives the limiting rod... 305. The limiting rod 305 drives the circular plate 307 until the limiting rod 305 is perpendicular to the limiting groove 308. The circular plate 307 is released, and the rebound force of the spring 306 drives the circular plate 307. The circular plate 307 drives the limiting rod 305 to slide within the push plate 302 until the limiting rod 305 is inserted into the limiting groove 308. This achieves the effect of convenient maintenance of the frequency converter receiver body 1, avoiding the situation where the frequency converter receiver body 1 is difficult to disassemble and maintain when the staff needs to maintain it, which would make it difficult to maintain the frequency converter receiver body 1 in good operating condition, and thus cause the frequency converter receiver body 1 to malfunction and fail to operate. This improves the practicality of the device.

[0033] When the screen on the inverter receiver body 1 is used, push the protective cover 46 to rotate on the arc surface of the rotating rod 44 until the protective cover 46 is fully opened. Then push the fixing rod 48 to slide in the support frame 47 until the fixing rod 48 is inserted into the fixing hole on the surface of the protective cover 46. When the screen on the inverter receiver body 1 is not used, pull the fixing rod 48 to slide in the support frame 47. The fixing rod 48 drives the baffle 49 until the baffle 49 touches the support frame 47. The torque of the torsion spring 45 drives the protective cover 46 to rotate on the arc surface of the rotating rod 44 until the protective cover 46 is completely attached to the operating housing 2. This achieves the effect of protecting the display screen on the operating housing 2. It avoids damage or screen distortion caused by the display screen on the operating housing 2 colliding with debris, which would make it difficult for the operator to see the inverter received data. This improves the practicality of the device.
