In order to improve the sealing performance of the cabinet door with the upper cabinet and the lower cabinet, a rubber strip can be filled between the upper column 1 and the lower column 4 and the cabinet door;

[0037] The upper cabinet includes a top plate 2, four upper columns 1 and three upper side plates 3. The four upper columns 1 are respectively fixed at the four corners of the bottom of the top plate 2, and the three upper side plates 3 are installed between the four upper columns 1 in a U-shaped shape.

[0038] The lower cabinet includes a bottom plate 6, four lower columns 4 and three lower side plates 5. The four lower columns 4 are respectively fixed at the four corners of the top of the bottom plate 6, and the three lower side plates 5 are installed in a U-shape between the four lower columns 4; a plug-in component is arranged on the upper column 1, and a limiting component is arranged on the lower column 4, and the limiting component is used to limit the plug-in component.

[0039] The connector includes two plug-in blocks 13, which are located between the two upper columns 1. A connecting rod 12 is fixed to one side of the plug-in block 13. The end of the connecting rod 12 passes through the interior of the upper column 1 and is fixed to a connecting block 18. Rollers 19 are installed on both sides of the bottom of the connecting block 18. A limiting ring 21 is fixed to the outside of the connecting rod 12 on one side of the upper column 1, and a spring 22 is sleeved between the upper column 1 and the limiting ring 21. The roller 19 is used instead of the connecting block 18 to directly contact the limiting plate 20, which can improve the convenience of moving the connecting block 18.

[0040] A protective tube 11 is fixed on one side of the upper column 1 outside the connecting rod 12 to protect the spring 22 and further improve the structural strength of the connecting rod 12 .

[0041] The limiting member includes two limiting plates 20, and the two limiting plates 20 are symmetrically arranged on the top of the lower column 4, one side of the limiting plate 20 is inclined, the roller 19 contacts the limiting plate 20, the connecting block 18 is a convex structure, and one end of the connecting block 18 is located between the two limiting plates 20; a fixing frame 9 is fixed on the opposite side of the two lower columns 4, a fixing box 10 is fixed between the two fixing frames 9, a guide column 23 is fixed laterally inside the fixing box 10, two slidable connecting plates 15 are symmetrically arranged on the outside of the guide column 23, and a tension spring 24 is arranged on the outside of the guide column 23 between the connecting plate 15 and the fixing box 10, one end of the tension spring 24 is connected to the connecting plate 15, and the other end of the tension spring 24 is connected to the fixing box 10, the top of the connecting plate 15 passes through the top of the fixing box 10, and a rectangular hole for moving the connecting plate 15 is opened on the top of the fixing box 10, and the limiting block 14 is fixed on the top of the connecting plate 15.

[0042] The insert block 13 and the limit block 14 are both triangular structures, and the edges of the insert block 13 and the limit block 14 are both arc-shaped transitions, so that when the insert block 13 descends, it can push the two limit blocks 14 to move toward each other.

[0043] A gear 26 is provided at the middle of the inner bottom of the fixed box 10. The gear 26 is symmetrically meshed with two tooth plates 25 with itself as the center. The two tooth plates 25 are respectively fixed to the two connecting plates 15. The tooth plates 25 are slidably connected to the fixed box 10 through slide rails. An adjusting rod 34 is fixed to the bottom of the gear 26. The bottom end of the adjusting rod 34 extends to the bottom of the fixed box 10 and is installed with an adjusting handle 16. The adjusting rod 34 is rotatably connected to the fixed box 10 through a rotating shaft.

[0044] Through the above technical solution:

[0045] Fix the top plate 2 to the upper column 1 and install the upper side plate 3 between the upper columns 1 to complete the assembly of the upper cabinet;

[0046] Fix the bottom plate 6 to the lower column 4, and install the lower side plate 5 between the lower columns 4 to complete the assembly of the lower cabinet (the above operation method and installation process are the same as those of the conventional low-voltage distribution cabinet, which is the existing technology and will not be described in detail here);

[0047] After the upper cabinet and the lower cabinet are assembled, they can be moved and transported respectively, and then assembled when they arrive at the designated location to form a complete low-voltage power distribution cabinet. Compared with the traditional integrated low-voltage power distribution cabinet, the present invention splits the low-voltage power distribution cabinet into an upper cabinet and a lower cabinet, which is convenient for transportation. The low-voltage power distribution cabinet can be divided into more parts through the connection component part of the upper cabinet and the lower cabinet of the present invention, depending on the actual situation. The present invention is temporarily described using only the upper cabinet and the lower cabinet;

[0048] During the assembly of the low-voltage distribution cabinet, the upper cabinet can be lifted to the top of the lower cabinet, and the upper column 1 is aligned with the lower column 4, and then the upper cabinet is slowly lowered. Figure 5 , Instruction Manual Figure 6 And the instruction manual Figure 7 As shown in the figure, the roller 19 at the bottom of the connecting block 18 will slowly move downward along the oblique edge of the limiting plate 20. Since the limiting plate 20 is in a fixed state, the connecting block 18 will pull the connecting rod 12 to move inside the upper column 1, thereby driving the two inserting blocks 13 to move in opposite directions. At this time, the spring 22 will be gradually compressed.

[0049] As the upper cabinet slowly descends, the two plug blocks 13 will also squeeze the two limit blocks 14 during the back-and-forth movement, causing the two limit blocks 14 to move toward each other. When the upper cabinet and the lower cabinet are assembled in place (that is, when the highest surface of the plug block 13 moves to the lowest surface of the limit block 14), at this time, since the sides of the two limit blocks 14 are no longer squeezed by the plug blocks 13, the limit blocks 14 will be pulled back to the initial position under the action of the tension spring 24, and the bottom of the limit block 14 will limit the top of the plug block 13 (as shown in the attached manual). Figure 5 ), thereby preventing the insertion block 13 from moving upward, thereby preventing the upper cabinet from separating from the lower cabinet;

[0050] When the assembled low-voltage distribution cabinet needs to be disassembled again, the adjusting handle 16 can be rotated to make the gear 26 drive the tooth plate 25 to move, and then drive the two connecting plates 15 to move toward each other, so that the limit block 14 is moved away from the top of the plug block 13. At the same time, the upper cabinet is lifted from the top of the lower cabinet so that the low-voltage distribution cabinet can be moved again; after the upper cabinet is separated from the lower cabinet, the connecting block 18 can be reset under the action of the spring 22 and the limit ring 21, so that the two plug blocks 13 can be restored to their initial positions, so that when the upper cabinet is combined with the lower cabinet again, the plug block 13 can still squeeze the limit block 14.

[0051] Embodiment 2:

[0052] The present invention provides as Figure 8-Figure 12 shown

[0053] The sealing assembly includes a connecting frame 8 in a C shape and four clamping frames 27 fixed at the corners of the connecting frame 8. The four clamping frames 27 are respectively located at the tops of the four lower vertical columns 4, and the clamping frames 27 are sleeved outside the limiting plate 20. Upper grooves 32 and lower grooves 33 are respectively formed at the inner top and inner bottom of the connecting frame 8. The bottom end of the upper side plate 3 is located in the upper groove 32, and the top end of the lower side plate 5 is located in the lower groove 33.

[0054] An upper airbag 28 is fixed inside the upper groove 32, and a lower airbag 29 is fixed inside the lower groove 33. After the upper airbag 28 and the lower airbag 29 are unfolded, they are both inflated airbags connected end to end.

[0055] Two gas cylinders 17 are arranged on one side of the connecting frame 8. The two gas cylinders 17 are respectively located on the sides of the two connecting plates 15. One of the gas cylinders 17 is communicated with the upper airbag 28 through a pipeline, and the other gas cylinder 17 is communicated with the lower airbag 29 through a pipeline. A piston 30 is arranged inside the gas cylinder 17, and a push rod 31 is fixed on one side of the piston 30. The end of the push rod 31 is in contact with the connecting plate 15.

[0056] Through the above technical solution:

[0057] Before the upper cabinet body and the lower cabinet body are assembled, the four clamping frames 27 are respectively placed on the four lower vertical columns 4 correspondingly. The bottom of the limiting plate 20 can be used to limit the clamping frames 27, thereby avoiding loosening of the clamping frames 27 and the connecting frame 8;

[0058] During the assembly process of the upper cabinet body and the lower cabinet body, the upper side plate 3 in the upper cabinet body will gradually extend into the upper groove 32 inside the connecting frame 8, and the lower side plate 5 in the lower cabinet body will gradually extend into the lower groove 33 inside the connecting frame 8. During this process, since the two limiting blocks 14 and the two connecting plates 15 move towards each other as a whole, the push rod 31 will move towards the outside of the gas cylinder 17 (the gas inside the gas cylinder 17 will actively expand outward to drive the push rod 31 to move), thereby reducing the pressure inside the upper airbag 28 and the lower airbag 29 to facilitate the entry of the upper side plate 3 and the lower side plate 5;

[0059] After the upper cabinet body and the lower cabinet body are assembled (that is, the bottom of the limiting block 14 limits the top of the inserting block 13), the tension spring 24 will pull the limiting block 14 back to the initial position again, thereby driving the piston 30 by the push rod 31 to be extruded into the gas cylinder 17, so that the upper airbag 28 and the lower airbag 29 expand, thereby squeezing and sealing the upper side plate 3 and the lower side plate 5, and at the same time, the strength of the connection between the upper cabinet body and the lower cabinet body can be further improved.

[0060] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
