Four wires are clamped at the bottom end of the device body, and a fixing device is provided on the surface of the device body. The fixing device includes two fixing blocks, and one side of the two fixing blocks close to each other is fixed on both sides of the device body. At this time, two magnets will push the rectangular plate due to the reason of opposite-sex repulsion, so that the rectangular plate drives the clamping block to slide, so that the clamping block no longer continues to squeeze the wire. At this time, when pulling the wire to make the wire pass through the round groove on the rectangular block, it plays the role of detaching the wire, thus solving the problem that since there is no device on the frequency converter to fix the wire, these wires are messily hanging on both sides of the frequency converter, and when re-wiring is required, since the cables are hanging and entangled with each other, they are prone to interfere with each other, and the replaced cable will drive other cables and is likely to cause the overall looseness. However, there are still the following problems:

Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0020] Please refer to Figures 1-4, the utility model provides an electrical automation frequency converter, which includes a frequency converter body 1. An installation mechanism 2 is fixedly connected to the back of the frequency converter body 1. The installation mechanism 2 includes side plates 3. A connecting plate 4 is fixedly connected to one side of the side plates 3. Bottom plates 5 and top plates 6 are respectively fixedly connected to the bottom and top of the connecting plate 4. A compression groove 8 is formed inside the top plate 6. A lifting slide plate 9 is slidably connected to the inner cavity of the compression groove 8. A lifting rod 10 is fixedly connected to the top of the lifting slide plate 9. The top of the lifting rod 10 passes through the compression groove 8 and is fixedly connected to a lifting pull knob 11. A return spring 12 is sleeved on the surface of the lifting rod 10. A positioning rod 13 is fixedly connected to the bottom of the lifting slide plate 9. A slot 7 is formed between the bottom plate 5 and the top plate 6. An insertion plate 14 is inserted into the inner cavity of the slot 7. Heat dissipation mechanisms 18 for heat dissipation are inlaid on both sides of the frequency converter body 1. A positioning through groove 15 is formed on the surface of the insertion plate 14. A positioning groove 16 is formed on the top of the bottom plate 5. The bottom of the positioning rod 13 passes through the positioning through groove 15 and is clamped with the positioning groove 16; when the lifting pull knob 11 is pulled upward, the upward movement of the lifting pull knob 11 drives the upward movement of the lifting rod 10, and the upward movement of the lifting rod 10 drives the upward movement of the lifting slide plate 9. On the one hand, the return spring 12 is compressed, and on the other hand, the positioning rod 13 is driven to move into the inner cavity of the compression groove 8. Then, the insertion plate 14 connected to the frequency converter body 1 is inserted into the inner cavity of the slot 7. At this time, the lifting pull knob 11 is released, and the lifting slide plate 9 returns under the action of the return spring 12, driving the return of the positioning rod 13, so that the bottom of the positioning rod 13 passes through the positioning through groove 15 and is clamped with the positioning groove 16, locking and fixing the insertion plate 14, and the installation of the frequency converter body 1 can be completed. When disassembling the frequency converter body 1, only need to pull upward to separate the positioning rod 13 from the slot 7 to disassemble the insertion plate 14 and the frequency converter body 1, without frequently screwing bolts, which is more convenient.

[0021] Refer to Figures 1-4 , further, threaded holes 17 are provided at the four corners of the side plates 3. One end of the insertion plate 14 is fixedly connected to the back of the frequency converter body 1, and the side plates 3 are installed on the surface of the electrification equipment through bolts.

[0022] Refer to Figures 1-4 , further, the heat dissipation mechanism 18 includes a heat dissipation cylinder 19. A threaded sleeve 22 is threadedly connected to one end of the heat dissipation cylinder 19. A filter screen 23 is clamped on the surface of the threaded sleeve 22. A heat dissipation fan 20 is fixedly installed in the inner cavity of the heat dissipation cylinder 19. A temperature control switch 21 is fixedly installed on one side of the heat dissipation fan 20, and the heat dissipation fan 20 is electrically connected to an external power supply through the temperature control switch 21. When the frequency converter body 1 works, heat will be generated inside. When the heat reaches the control range of the temperature control switch 21, the heat dissipation fan 20 works to pump external air into the frequency converter body 1 for heat and cold replacement, thereby dissipating heat from the inside of the frequency converter body 1.

[0023] Refer to Figures 1-4, Further, the return spring 12 is located in the inner cavity of the compression groove 8, and the bottom of the return spring 12 abuts against the top of the lifting slide plate 9 to assist the lifting slide plate 9 in returning to its original position.

[0024] During specific use, first, the side plate 3 is installed on the surface of the electrified equipment through bolts. Then, the lifting knob 11 is pulled upward. The upward movement of the lifting knob 11 drives the upward movement of the lifting rod 10, and the upward movement of the lifting rod 10 drives the upward movement of the lifting slide plate 9. On the one hand, the return spring 12 is compressed, and on the other hand, the positioning rod 13 is driven to move into the inner cavity of the compression groove 8. Then, the plug board 14 connected to the inverter body 1 is inserted into the inner cavity of the slot 7. At this time, the lifting knob 11 is released. The lifting slide plate 9 returns to its original position under the action of the return spring 12, driving the return of the positioning rod 13, so that the bottom of the positioning rod 13 passes through the positioning through groove 15 and is clamped with the positioning groove 16 to lock and fix the plug board 14, and the installation of the inverter body 1 can be completed. When disassembling the inverter body 1, it is only necessary to pull upward to separate the positioning rod 13 from the slot 7 to disassemble the plug board 14 and the inverter body 1, without the need to frequently turn the bolts, which is more convenient. When the inverter body 1 works, heat will be generated inside. When the heat reaches the control range of the temperature control switch 21, the cooling fan 20 works to draw external air into the inverter body 1 for heat exchange, so as to dissipate the heat inside the inverter body 1. The threaded sleeve 22 connected with the filter net 23 is threadedly connected with the heat dissipation cylinder 19 and can be disassembled, which is convenient for replacing and maintaining the filter net 23.
