[0031] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. 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.

[0032] Refer to Figures 1 - 3 , an embodiment provided by the present utility model: A highly stable plug-in box for connecting bus ducts, including a bus duct housing 1. First, place the bus duct housing 1 in a suitable position. The front end of the bus duct housing 1 is movably connected to a box body 2. The front end of the box body 2 is detachably connected to a box door, and a handle is fixedly connected to the front end of the box door. Open the box door at the front end of the box body 2, align the front side of the bus duct housing 1 with the rear side of the box body 2. Threaded connections are provided at the four corners inside the rear side of the box body 2 with mounting posts 3, which can pass the mounting posts 3 through the through holes of the bus duct housing 1 and the box body 2. A cavity 4 is provided inside the mounting post 3, and a fixed post 5 is slidably connected to the inner wall of the cavity 4. Rotating plates 6 are rotatably connected to the outer sides of the left and right sides of the bottom of the fixed post 5. Press the two rotating plates 6 inward, and under the pressing of the rotating plates 6, the internal fixed post 5 slides along the inner wall of the cavity 4.

[0033] The bottom of the fixed column 5 is fixedly connected with an extension rod 7. During the sliding process of the fixed column 5, the internal extension rod 7 will be squeezed. The outer part of the extension rod 7 is slidably connected to the inner wall of the cavity 4. The extension rod 7 slides inward to contact the bottom wall of the cavity 4. A first spring 8 is sleeved outside the extension rod 7. When the extension rod 7 moves, the first spring 8 will be compressed by force. One end of the first spring 8 is fixedly connected to the bottom of the fixed column 5, and the other end of the first spring 8 is fixedly connected to the inner wall of the cavity 4. A limiting component is fixedly connected to the outside of the mounting column 3, and the limiting component can limit the fixed column 5.

[0034] The limiting component includes two square sliding grooves 9. The outer part of the rotating plate 6 is rotatably connected to the inner wall of the square sliding grooves 9. The two square sliding grooves 9 are respectively opened on the left and right sides of the mounting column 3. The outer part of the rotating plate 6 is in contact with the inner wall of the box body 2. When the rotating plate 6 coincides with the inner wall of the square sliding groove 9, the square sliding groove 9 can limit the rotating plate 6. When the rotating plate 6 is released, the rotating plate 6 contacts the inner wall of the box body 2. A limiting plate 10 is fixedly connected to the top of the fixed column 5, and the limiting plate 10 can limit the fixed column 5. A locking collar 11 is threadedly connected to the outside of the mounting column 3. By tightening the locking collar 11, the installation of the busbar housing 1 and the box body 2 is completed by using the mounting column 3.

[0035] Refer to Figure 2 、 Figure 4 And Figure 5 , a clamping plate 13 is fixedly connected to the rear side inside the box body 2. A plurality of buffer components are arranged outside the clamping plate 13, and the buffer components can protect the box body 2. The buffer component includes a second connecting rod 15. The other end of the second connecting rod 15 is rotatably connected to a first connecting rod 14. When the box body 2 shakes during use, the first connecting rod 14 and the second connecting rod 15 inside will be squeezed and rotate. The other end of the first connecting rod 14 is rotatably connected to a fixed block 12. The top of the first connecting rod 14 is rotatably connected to a sleeve column 16. The sleeve column 16 can fix a second spring 17. The second spring 17 is fixedly connected to the adjacent sides of the two sleeve columns 16. During the rotation process, the second spring 17 will be pulled and stretched to both sides. Through the elastic property of the second spring 17 itself, one end of the second connecting rod 15 is rotatably connected to the front end of the clamping plate 13, and the shaking between the fixed block 12 and the clamping plate 13 can be absorbed, so as to buffer between the box body 2 and the fixed block 12.

[0036] Working principle: First, place the busbar trunking housing 1 in a suitable position. Then, open the door at the front end of the box body 2. After that, align the front side of the busbar trunking housing 1 with the rear side of the box body 2. Press the rotating plates 6 on both sides inward. Under the pressing of the rotating plates 6, the internal fixing columns 5 slide along the inner wall of the cavity 4. During the sliding process of the fixing columns 5, they will squeeze the internal extension rods 7. The extension rods 7 slide inward and contact the bottom wall of the cavity 4. At the same time, the first spring 8 is compressed under force. When the rotating plates 6 coincide with the inner wall of the square chute 9, the mounting columns 3 can be passed through the through holes of the busbar trunking housing 1 and the box body 2. Then, release the rotating plates 6. The rotating plates 6 contact the inner wall of the box body 2. At this time, tighten the locking collar 11, thereby realizing the installation of the busbar trunking housing 1 and the box body 2 by using the mounting columns 3.

[0037] When the box body 2 shakes during use, the internal connecting rod one 14 and connecting rod two 15 will be squeezed and rotate under force. During the rotation process, the second spring 17 will be pulled and stretched to both sides. Through the elastic characteristics of the second spring 17 itself, the shaking between the fixed block 12 and the clamping plate 13 can be absorbed, so as to buffer between the box body 2 and the fixed block 12.

[0038] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
