[0020] Example 1

[0021] like Figures 1-3 As shown in the figure, the splicing disconnect switch base proposed in this embodiment includes two first mounting side plates 1, two second mounting side plates 2, a rectangular frame 5, and two top inclined plates 3.

[0022] Two first mounting side plates 1 are symmetrically arranged, and a mounting base 101 is vertically connected to the bottom end of the first mounting side plate 1; two second mounting side plates 2 are arranged side by side between the two first mounting side plates 1; two top inclined plates 3 are symmetrically arranged at the top ends of the two first mounting side plates 1, and L-shaped limiting blocks 7 are connected to both ends of the bottom surface of the top inclined plates 3. Multiple second limiting holes 11 are opened at the top ends of the two first mounting side plates 1 for the ends of the L-shaped limiting blocks 7 to be inserted; both ends of the top of the first mounting side plate 1 are provided with inclined surfaces, and the slope of the inclined surfaces on both sides is the same as the slope of the corresponding top inclined plate 3.

[0023] Multiple first limiting blocks 8 are connected to the rectangular frame 5. Multiple U-shaped pieces 6 are provided on the inner walls of both the first mounting side plate 1 and the second mounting side plate 2 for the first limiting blocks 8 to engage. In the installed state, the rectangular frame 5 is located below the multiple U-shaped pieces 6. Two sets of limiting components are symmetrically installed on the rectangular frame 5. The limiting components include a slider 15, a second limiting block 91, two third limiting blocks 92, and two connecting rods 14. The second limiting block 91 movably passes through the end of the rectangular frame 5. The second mounting side plate 2 has a first limiting hole 10 for the second limiting block 91 to engage. The slider 15 is located inside the rectangular frame 5 and connected to the second limiting block 91. The third limiting block 92 moves through the two sides of the rectangular frame 5 adjacent to the two first mounting side plates 1. The two ends of the first mounting side plates 1 are provided with third limiting holes 16 for the third limiting block 92 to be inserted. The two connecting rods 14 are rotatably connected to the two third limiting blocks 92 respectively. The other end of the two connecting rods 14 is rotatably connected to the slider 15. The rectangular frame 5 is equipped with a driving assembly for driving the sliders 15 on both sides to move closer or further apart. The driving assembly includes a bidirectional lead screw 12 and a knob 13. The bidirectional lead screw 12 is rotatably installed inside the rectangular frame 5. The two sliders 15 are threadedly connected to the bidirectional lead screw 12. The knob 13 is installed in the middle of the bidirectional lead screw 12.

[0024] The working principle of this technical solution is as follows:

[0025] First stage of assembly: The two first mounting side plates 1 are placed symmetrically on a plane. The inclined surfaces at both ends of the top of the first mounting side plate 1 provide good guidance and adaptation for the subsequent installation of the top inclined plate 3, while the mounting base 101 connected vertically at its bottom provides stable support for the entire base. It should be noted that the mounting base 101 also has mounting holes. Then, the top inclined plate 3 is installed. During installation, the end of the L-shaped limiting block 7 at one end of the top inclined plate 3 is carefully inserted into the inside of the second limiting hole 11 of one side of the first mounting side plate 1. This completes the initial connection between the top inclined plate 3 and one side of the first mounting side plate 1. Then, the top inclined plate 3 on the other side is installed in the same way. This cooperation between the L-shaped limiting block 7 and the second limiting hole 11 achieves a stable connection between the top inclined plate 3 and the first mounting side plate 1, while also ensuring the symmetry and stability of the entire structure.

[0026] Installation of rectangular frame 5: After the top inclined plate 3 is installed, the entire device is inverted. At this time, the two second mounting side plates 2 are placed at both ends between the two first mounting side plates 1. The second mounting side plates 2 play a connecting and reinforcing role in the entire base structure, making the overall structure of the base more stable. Then, the rectangular frame 5 is installed. The side of the rectangular frame 5 with the first limiting block 8 faces the first mounting side plate 1 and the second mounting side plate 2, so that the multiple first limiting blocks 8 are inserted into the inside of the multiple U-shaped parts 6 respectively. This cooperation between the first limiting block 8 and the U-shaped parts 6 realizes the horizontal limiting of the first mounting side plate 1 and the second mounting side plate 2, ensuring the stability of the rectangular frame 5 in the horizontal direction.

[0027] Final locking stage: Two sets of limiting components are symmetrically installed on the rectangular frame 5. When limiting the second mounting side plate 2 and the first mounting side plate 1 in the vertical direction, the operator turns the knob 13, which drives the bidirectional lead screw 12 to rotate. The rotation will cause the two sliders 15 to move away from each other. The sliders 15 are connected to the second limiting block 91. As the sliders 15 move, the end of the second limiting block 91 is inserted into the first limiting hole 10 opened on the second mounting side plate 2, realizing the vertical limiting of the second mounting side plate 2. At the same time, the movement of the sliders 15 drives the two third limiting blocks 92 to move through the two connecting rods 14. The first mounting side plate 1 has third limiting holes 16 opened at both ends. The third limiting blocks 92 are inserted into the third limiting holes 16, completing the vertical limiting of the first mounting side plate 1. This method of driving the limiting components through the driving components realizes the all-round limiting of all parts of the entire spliced ​​disconnect switch base, ensuring the stability of the base structure. After completing all the above installation steps, the device is inverted again to restore the original state.

[0028] In summary, the various components in this technical solution are tightly connected together through a clever limiting structure. This splicing design has obvious advantages over the traditional method of using a large number of fasteners. It not only facilitates installation and disassembly, improving operational efficiency, but also makes it more convenient for later maintenance and component replacement.

[0029] Example 2

[0030] like Figure 1 and Figure 2 As shown, the splicing disconnect switch base proposed in this embodiment, compared with the first embodiment, further includes an intermediate top plate 4, which is parallel to the rectangular frame 5. The top of the first mounting side plate 1 is provided with a horizontal part parallel to the intermediate top plate 4. Both ends of the bottom surface of the intermediate top plate 4 are connected with L-shaped limiting blocks 7. The upper ends of the two first mounting side plates 1 are also provided with a number of second limiting holes 11.

[0031] Sealing strips 41 are connected to both sides of the middle top plate 4, and the two sealing strips 41 cover the gaps on both sides of the middle top plate 4 respectively.

[0032] In this embodiment, an intermediate top plate 4 is also added. The intermediate top plate 4 is parallel to the rectangular frame 5. Before the device is inverted, the intermediate top plate 4 needs to be installed. The two ends of the bottom surface of the intermediate top plate 4 are also connected with L-shaped limiting blocks 7. The L-shaped limiting blocks 7 at both ends of the intermediate top plate 4 are respectively inserted into the inner side of the second limiting holes 11 of the first mounting side plates 1 on both sides, thereby completing the limiting of the intermediate top plate 4. The sealing strips 41 connected to both sides of the intermediate top plate 4 can cover the gaps on both sides of the intermediate top plate 4, playing a role in sealing and protection. After inversion, the intermediate top plate 4 is in contact with the plane of the table, which enhances the stability of the placement of the disconnect switch base.

Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
