[0026] In the present embodiment: to solve the technical problems existing in the prior art, as disclosed in the background art above, "the existing variable frequency cabinet often works with multiple groups of variable frequency cabinets simultaneously, lacks corresponding connecting structures between the cabinet bodies, has low stability, and is prone to tipping under the influence of external forces, thereby affecting the normal operation", in combination with use, this problem is obviously a real problem and is relatively difficult to solve. In view of this, to solve the above-mentioned problems, the guide foot 2 and the lifting plate 3 are added on this basis.

[0027] Further:

[0028] As shown in the figure: Figure 1 - Figure 6 As shown in the figure:

[0029] In combination with the above content: the variable frequency cabinet body 1 further comprises a guide foot 2, a lifting plate 3, a spring 4, a rack 5, a stabilizing plate 6, a gear 7, a threaded rotating shaft 8, a directional block 9, a screw sleeve 10, an adjusting sleeve 11, a positioning piece 12, a plug-in plate 13, and a plug-in groove 14.

[0030] One side surface of the variable frequency cabinet body 1 is fixedly installed with the guide foot 2 which is slidingly connected with the lifting plate 3, the surface of the guide foot 2 is further sleeved with the spring 4, and the two ends of the spring 4 are respectively fixedly connected with the lifting plate 3 and the surface of the variable frequency cabinet body 1, one side of the lifting plate 3 is further fixedly connected with one end of the rack 5, the rack 5 is slidingly connected with the stable plate 6 which is fixedly installed on the inner surface of the variable frequency cabinet body 1, and the rack 5 is further meshingly connected with one side of the gear 7, the surface of the gear 7 is fixedly installed with the threaded rotating shaft 8 which is rotationally connected with the variable frequency cabinet body 1, the surface of the threaded rotating shaft 8 is threadedly connected with the screw sleeve 10 which is rotationally connected with the adjusting sleeve 11, and the end of the threaded rotating shaft 8 away from the gear 7 is further fixedly installed with the directional block 9 which is slidingly connected with the inner surface of the adjusting sleeve 11, one end of the adjusting sleeve 11 is further fixedly installed with the positioning piece 12 which is abuttingly connected with the surface of the variable frequency cabinet body 1, the side surface of the positioning piece 12 away from the adjusting sleeve 11 is further fixedly connected with the plug plate 13, and the plug plate 13 is slidingly connected with the plug groove 14, and the plug groove 14 is opened on the other side surface of the variable frequency cabinet body 1.

[0031] In this embodiment: when the frequency conversion cabinet 1 needs to be spliced with the frequency conversion cabinet 1, the lifting plate 3 can be inserted into the bottom of the lifting plate 3 by a forklift or a belt sling and the like, and the frequency conversion cabinet 1 is lifted or hoisted, at this time, the plug plate 13 is in a horizontal state, and the spring 4 is in a relaxed state. When hoisted, the lifting plate 3 is first subjected to external force to produce sliding between the lifting plate 3 and the guide foot 2, and the lifting plate 3 and the frequency conversion cabinet 1 will compress the spring 4 arranged between them. At the same time, the lifting plate 3 will push the rack 5 and the stable plate 6 to produce sliding between them, and the rack 5 and the gear 7 will produce meshing and drive the threaded rotating shaft 8 and the frequency conversion cabinet 1 to rotate. With the gradual lifting of the lifting plate 3, the lifting plate 3 will be attached to the bottom surface of the frequency conversion cabinet 1, and the spring 4 will also be contracted to the extreme value. The gear 7 and the threaded rotating shaft 8 drive the adjusting sleeve 11, the positioning piece 12 and the plug plate 13 to rotate by 90 degrees, and the plug plate 13 is in a vertical state. At this time, the upward force can be continuously applied to the lifting plate 3 and the frequency conversion cabinet 1, and the frequency conversion cabinet 1 will be gradually lifted off the ground. Then the frequency conversion cabinet 1 can be transferred to the side of the frequency conversion cabinet 1 provided with the slot 14 and the two frequency conversion cabinets 1 are in a parallel state. Then the frequency conversion cabinet 1 in the lifting state can be moved horizontally to the position of the slot 14. At this time, the plug plate 13 in the vertical state can be smoothly inserted into each slot 14 until the positioning piece 12 and the surface of the frequency conversion cabinet 1 are attached. Finally, the hoisted frequency conversion cabinet 1 can be slowly lowered, and at this time the plug plate 13 will be lowered synchronously inside the slot 14 until the bottom of the frequency conversion cabinet 1 contacts the ground. When the external device and the lifting plate 3 are separated, the lifting plate 3 will slide again between the guide foot 2 and be reset under the pushing of the spring 4. The rack 5 will also drive the gear 7, the threaded rotating shaft 8, the plug plate 13 and the like to rotate by 90 degrees in the opposite direction under the pulling force of the lifting plate 3. The plug plate 13 rotating in the slot 14 will be difficult to separate from the slot 14, thereby ensuring the tightness of the connection between the frequency conversion cabinet 1 and the frequency conversion cabinet 1.

[0032] When the frequency conversion cabinet 1 has high heat dissipation requirements and sufficient heat dissipation space is required between the frequency conversion cabinets 1, the threaded sleeve 10 arranged on the surface of the threaded rotating shaft 8 can be rotated before the frequency conversion cabinet 1 is lifted. The threaded rotating shaft 8 will produce threaded rotation between the threaded sleeve 10, and the threaded sleeve 10 will produce rotation between the adjusting sleeve 11 and push the adjusting sleeve 11 and the plug plate 13 away from the surface of the frequency conversion cabinet 1. The directional block 9 arranged at the end of the threaded rotating shaft 8 inside the adjusting sleeve 11 will slide along the inner surface of the adjusting sleeve 11 to ensure that the angle of the plug plate 13 will not change under the rotation of the threaded rotating shaft 8 and the threaded sleeve 10. When the position of each plug plate 13 from the frequency conversion cabinet 1 is adjusted to the appropriate position, the frequency conversion cabinet 1 can be spliced.

[0033] Further more:

[0034] In an optional embodiment, rectangular slots are provided on both sides of the lower surface of the frequency converter cabinet 1, and the rectangular slots are matched with the position of the lifting plate 3.

[0035] In this embodiment, the slot below the inverter cabinet 1 provides good operating space when the external device lifts the inverter cabinet 1 by the lifting plate 3, providing effective space conditions for the movement of the lifting plate 3. At the same time, the lifting plate 3 located at the bottom is concealed and is not easily affected by external factors. It can also prevent displacement after the inverter cabinet 1 and the connection between the inverter cabinet 1 and the slot 14 are formed, and can keep the connection between the plug plate 13 and the slot 14 stable.

[0036] Furthermore:

[0037] In an optional embodiment, the surface of the lifting plate 3 is also provided with through holes that match the guide legs 2.

[0038] In this embodiment, the through holes on the surface of the lifting plate 3 allow the lifting plate 3 to slide and move with the guide leg 2 when it is lifted, thereby providing a stable power foundation for the movement of the rack 5 and the rotation of the gear 7.

[0039] Furthermore:

[0040] In an optional embodiment, the tooth blocks continuously arranged on the surface of gear 7 have an angle of 90 degrees.

[0041] In this embodiment, the toothed blocks arranged in a continuous 90-degree pattern can only form a 90-degree rotation angle when the rack 5 drives the gear 7 to rotate, so that the insert plate 13 can change before and after entering the slot 14, thereby connecting the frequency converter cabinet 1 and the frequency converter cabinets 1 together.

[0042] Furthermore:

[0043] In an optional embodiment, there are four sets of gear 7, threaded shaft 8, directional block 9, threaded sleeve 10, adjusting sleeve 11, positioning plate 12 and insert plate 13, and the four sets are arranged in parallel to each other, and the slot 14 is opened in a position corresponding to it.

[0044] In this embodiment, a total of four sets of gears 7, threaded shafts 8, and insert plates 13 are provided to enable a more robust connection between the frequency converter cabinet 1 and the frequency converter cabinet 1 when they are spliced ​​together, thereby making the overall stability higher and the connection more stable.

[0045] Furthermore:

[0046] In an optional embodiment, the orientation block 9 is cuboid in shape, and the inner surface of the adjusting sleeve 11 is provided with a rectangular groove that matches the orientation block 9.

[0047] In this embodiment: the cuboid-shaped orientation block 9 and the groove starting from the inner surface of the adjusting sleeve 11 can drive the positioning piece 12 and the plug plate 13 to rotate synchronously when the gear 7 and the threaded rotating shaft 8 rotate, and can ensure that the angle of the positioning piece 12 and the plug plate 13 does not change when the distance between the positioning piece 12 and the plug plate 13 and the frequency conversion cabinet 1 lengthens, thereby being beneficial to the stability of the butt joint between the plug plate 13 and the plug groove 14.

[0048] The working principle and use process of the utility model: when it is needed to splice the frequency conversion cabinet 1 and the frequency conversion cabinet 1, the lifting plate 3 can be inserted into the bottom of the lifting plate 3 through a forklift or a belt sling and the like, the frequency conversion cabinet 1 is lifted or hoisted, at this time, the plug plate 13 is in a horizontal state, and the spring 4 is in an expanded state, when hoisting, the lifting plate 3 is first subjected to external power to make it slide between the guide foot 2, the lifting plate 3 and the frequency conversion cabinet 1 compress the spring 4 arranged between them, and the lifting plate 3 will push the rack 5 and the stabilizing plate 6 to slide in the process of gradually lifting, the rack 5 and the gear 7 are engaged and drive the threaded rotating shaft 8 and the frequency conversion cabinet 1 to rotate, with the gradual lifting of the lifting plate 3, the lifting plate 3 will be attached to the bottom surface of the frequency conversion cabinet 1, the spring 4 will also be contracted to the extreme value, the gear 7 and the threaded rotating shaft 8 drive the adjusting sleeve 11, the positioning piece 12 and the plug plate 13 to rotate by 90 degrees, and the plug plate 13 is in a vertical state, at this time, the upward force can be continuously applied to the lifting plate 3 and the frequency conversion cabinet 1, and the frequency conversion cabinet 1 will be gradually lifted off the ground, then the frequency conversion cabinet 1 can be transferred to the side of the frequency conversion cabinet 1 provided with the plug groove 14 and make the two frequency conversion cabinets 1 in a parallel state, then the frequency conversion cabinet 1 in the lifting state can be moved horizontally to the position of the plug groove 14, at this time, the plug plate 13 in the vertical state can be smoothly inserted into each plug groove 14 until the positioning piece 12 and the surface of the frequency conversion cabinet 1 are attached, finally, the frequency conversion cabinet 1 being hoisted can be slowly lowered, and at this time, the plug plate 13 will be lowered synchronously in the plug groove 14 until the bottom of the frequency conversion cabinet 1 contacts the ground, when the external device and the lifting plate 3 are separated, the lifting plate 3 will slide again between the guide foot 2 and be reset under the pushing of the spring 4, the rack 5 will also drive the gear 7, the threaded rotating shaft 8, the plug plate 13 and the like to rotate reversely by 90 degrees under the pulling force of the lifting plate 3, and the plug plate 13 rotating in the plug groove 14 will be difficult to separate from the plug groove 14, thereby being capable of ensuring the tightness of the connection between the frequency conversion cabinet 1 and the frequency conversion cabinet 1.
