DETAILED DESCRIPTION

[0045] 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. Obviously, 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.

[0046] Reference Figure 1 -Attached Fig. 9 , an associated inverter mounting assembly, comprising:

[0047] A plurality of static components are arranged in a fixed-size array inside the control box;

[0048] At least two dynamic components are installed on the inverter by bolting;

[0049] The static magnet 1 is a part of the static component, has two magnetic poles, N or S, and is fixedly arranged between the control box;

[0050] The dynamic magnet 2 is a part of the dynamic component, has two magnetic poles, N or S, and is movably arranged between the frequency converter;

[0051] The dynamic magnet 2 can change its positional relationship with the static magnet 1. The first position of the dynamic magnet 2 is before the dynamic magnet 2 and the static magnet 1 are magnetically attracted to each other, and the second position of the dynamic magnet 2 is after the dynamic magnet 2 and the static magnet 1 are magnetically attracted to each other.

[0052] Through the above technical solution, the dynamic component connected to the inverter is installed and connected with the static component in a magnetic way. Since the size of the static components in the control box is fixed and arranged in an array, the static components form a standard in different control boxes, and the inverter can be installed inside the control box through the cooperation of the static components and the dynamic components.

[0053] Static components include:

[0054] The disc 3 is fixedly connected to the inside of the control box;

[0055] The ring 4 is coaxially fixedly connected to the disk 3;

[0056] The static magnet 1 is fixedly arranged in the circular ring 4 .

[0057] Dynamic components include:

[0058] The connecting plate 5 is connected to the frequency converter by bolts;

[0059] A fixing ring 6 is fixedly connected to the connecting plate 5;

[0060] The positioning plate 7 is located in the middle area of ​​the fixing ring 6;

[0061] The plug post 8 is rotatably connected to the positioning plate 7, and its outer diameter is the same as the inner diameter of the ring 4. The dynamic magnet 2 is located in the plug post 8;

[0062] Among them, two connection points are found in the inner circle of the fixing ring 6, the angle between the line segments between the two connection points and the virtual midpoint of the fixing ring 6 is 180°, and the connection points are connected to the positioning plate 7 through the wire 12.

[0063] The positioning disc 7 is symmetrically provided with two winding structures, which are used to wind the wire 12 and always keep the wire 12 in a taut state. The winding structure includes:

[0064] Two extension plates 9 are fixedly connected to the outer ring of the positioning plate 7;

[0065] A fixed shaft 10, fixed between two extension plates 9;

[0066] The sleeve 11 is slidably sleeved outside the fixed shaft 10, and its outer wall is connected to one end of the wire 12;

[0067] The elastic groove 13 is provided inside the sleeve 11;

[0068] The torsion spring 14 is sleeved on the outer wall of the fixed shaft 10 and is located inside the elastic groove 13 , and its two ends are connected to the fixed shaft 10 and the sleeve 11 respectively.

[0069] A receiving groove 15 is provided inside the positioning plate 7, and a rotating shaft 16 is rotatably connected inside the receiving groove 15. The outer wall of the rotating shaft 16 is fixedly sleeved with a first gear 17. The first gear 17 can rotate in the receiving groove 15. One end of the rotating shaft 16 is coaxially fixedly connected to the plug post 8. A second gear 18 is also rotatably connected in the receiving groove 15. The first gear 17 and the second gear 18 are meshingly connected. Part of the second gear 18 is located outside the positioning plate 7. By moving the second gear 18, the rotation of the plug post 8 is transmitted and driven, thereby determining the positional relationship between the dynamic magnet 2 and the static magnet 1.

[0070] A locking structure is provided on the positioning disk 7 to lock the rotation of the sleeve 11, thereby keeping the installed frequency converter stable and free from shaking in the control box.

[0071] The locking structure includes a drive disk 19, which is fixedly connected to one end of the rotating shaft 16. The drive disk 19 has two symmetrical protrusions. The positioning disk 7 elastically slides to set two symmetrical blocks 20. The drive disk 19 rotates to make the protrusions push the blocks 20 toward the direction of the sleeve 11. After being released, the rotation of the sleeve 11 is prevented by friction.

[0072] The clamping block 20 is fixedly connected to the connecting block 21, and the connecting block 21 is fixedly connected to the guide block 22. Both the guide block 22 and the clamping block 20 are arc-shaped. The connecting block 21 is slidably connected to the rectangular frame 23, and the rectangular frame 23 is fixedly connected to the positioning plate 7. A compression spring 24 is arranged on the outer shell of the connecting block 21, and the two ends of the compression spring 24 are respectively connected to the rectangular frame 23 and the guide block 22.

[0073] The locking structure also includes an extension ring 25, the outer ring of the extension ring 25 is fixedly sleeved with a rubber ring 26, the outer ring curvature of the rubber ring 26 is adapted to the inner ring curvature of the clamping block 20, the extension ring 25 is coaxially fixedly connected to the sleeve 11, and the extension plate 9 located between the extension ring 25 and the sleeve 11 is provided with a through hole 27, the diameter of the through hole 27 is the outer diameter of the extension ring 25, and the outer diameter of the extension ring 25 is smaller than the outer diameter of the sleeve 11.

[0074] There are two static magnets 1, which are symmetrically arranged inside the ring 4, and have N and S poles respectively. There are two dynamic magnets 2, which are symmetrically arranged inside the plug 8, and have N and S poles respectively. The static magnet 1 is arranged at an angle. When the static magnet 1 and the dynamic magnet 2 repel each other, the plug 8 can automatically detach from the ring 4, making it convenient and quick to disassemble and assemble the inverter in the control box.

[0075] Working principle:

[0076] The internal mounting surface of the control box has a dense arrangement of static components arranged in a complete array, and the dynamic components are installed on the inverter at the positions where the screw holes originally existed by bolts;

[0077] Determine the position of the inverter in the control box, manually adjust the position of the positioning plate 7 in the inner area of ​​the fixing ring 6, insert the plug 8 into the inner part of the ring 4, and the two are connected by magnetic attraction;

[0078] During magnetic attraction, the plug 8 entering the inside of the circular ring 4 rotates, causing the two protruding parts of the driving disk 19 to squeeze the two guide blocks 22 respectively, further squeezing and contracting the compression spring 24, so that the clamping block 20 approaches the rubber ring 26 and finally contacts the rubber ring 26 to limit the rotation of the sleeve 11, thereby limiting the retraction and release of the wire 12, and stabilizing the position of the positioning disk 7 in the internal area of ​​the fixed ring 6.

[0079] It should be noted that:

[0080] The blank area in the center of the fixing ring 6 can completely accommodate four static components arranged in adjacent arrays;

[0081] The torsion spring 14 located inside the elastic groove 13 is always in a deformed state to keep the wire 12 always in a taut state;

[0082] The compression spring 24 located between the rectangular frame 23 and the guide block 22 relies on its own elastic force to squeeze the driving disk 19, so that the two protruding parts of the driving disk 19 are away from the guide block 22. At this time, the clamping block 20 does not interfere with the rubber ring 26. When the driving disk 19 causes the protruding part to reversely squeeze the guide block 22, the compression spring 24 further contracts. At this time, the clamping block 20 interferes with the rubber ring 26 and the sleeve 11 cannot rotate.

[0083] Reference Fig. 9 If the pin 8 rotates to cause the dynamic magnet 2 and the static magnet 1 to repel each other, it will help the pin 8 to quickly detach from the ring 4.

[0084] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
