[0026] Reference Figure 1 This embodiment provides a box bottom shell with a reinforced structure, including a load-bearing component 1, which includes a bottom shell 11;

[0027] The fixing component 2 includes a support column 21 disposed inside the bottom shell 11 and a fixing column 22 disposed above the support column 21;

[0028] Mounting assembly 3 includes a mounting block 31 located inside the bottom shell 11 and a positioning post 32 located inside the bottom shell 11.

[0029] The sealing assembly 4 includes a sealing strip 43 disposed above the bottom shell 11;

[0030] 5, including a middle frame 51 located above the bottom shell 11.

[0031] The supporting component 1 also includes a baffle 111 disposed above the bottom shell 11, a heat dissipation groove 112 disposed on the outer side of the bottom shell 11, and a pad 12 disposed below the bottom shell 11.

[0032] The heat dissipation slots 112 are arranged around the bottom shell 11.

[0033] The bottom shell 11 is made of high-strength engineering plastic injection molding and has heat dissipation grooves 112 around it, which in turn dissipate heat from the inside of the meter box.

[0034] The base shell 11 is supported by evenly distributed support columns 21 on its inner perimeter, with fixed columns 22 connected above the support columns 21. The middle frame 51 is fixedly connected to the base shell 11 via connecting columns 52, forming an overall reinforced structure.

[0035] The sealing strip 43 is installed in the bearing groove 41 above the bottom shell to ensure waterproof performance.

[0036] Usage process: During installation, first fix each component in the bottom shell 11 with the mounting block 31 and positioning post 32, install the sealing strip 43 into the bearing groove 41, and finally install and fix the middle frame 51, connecting post 52 and bottom shell 11 with bolts 13. Finally, install the top cover and ensure that the sealing strip 43 is pressed tightly, thereby improving the overall strength and impact resistance of the meter box and effectively coping with extreme weather conditions.

[0037] Example 2, refer to Figures 1-3 This is the second embodiment of the present invention. Unlike the previous embodiment, it also includes a fixing component 2, which further includes a fixing hole 221 located inside the fixing post 22. A spiral groove is provided inside the fixing hole 221, and a bolt 13 is installed in the spiral groove. The support posts 21 are arranged in an array around the inner perimeter of the bottom shell 11.

[0038] The spiral groove inside the fixing hole 221 is designed as a double thread, which improves the fixing strength and seismic performance of the bolt 13. At the same time, the number of arc-shaped support plates on the outside of the positioning column 32 is increased to 6, providing a more uniform distribution of support force.

[0039] Usage: When installing in areas with strong winds, use bolt 13 in conjunction with the threaded hole. By embedding bolt 13 into the threaded hole, the connection between the bottom shell 11 and the middle frame 51 is more secure, ensuring the stability of the meter box under extreme weather conditions.

[0040] Example 3, referring to Figures 1-3 This is the third embodiment of the present invention. Unlike the previous embodiment, it also includes a sealing component 4, which includes a bearing groove 41 above the bottom shell 11 and positioning blocks 42 disposed on the bearing groove 41. The positioning blocks 42 are arranged in an array at the four corners of the bearing groove 41.

[0041] The positioning block 42 enables the sealing strip 43 to be accurately positioned at the four corners of the bearing groove 41 and to fit together.

[0042] Usage process: First, place the sealing strip 43 into the bearing groove 41, then attach the middle frame 51 to the sealing strip 43, then connect the middle frame 51 to the bottom shell 11 with bolts 13, and press the sealing strip 43 to ensure waterproof performance.

[0043] Example 4, refer to Figures 1-3 This is the third embodiment of the present utility model. Unlike the previous embodiment, it also includes an installation component 3, which includes an installation groove 311 located inside the installation block 31 and a positioning groove 321 located inside the positioning post 32. An arc-shaped support plate is provided on the outer side of the positioning post 32, and the arc-shaped support plate is arranged in a circumferential array on the outer side of the positioning post 32.

[0044] 5 also includes a positioning hole 511 opened on the inner side of the middle frame 51, a connecting post 52 is provided on the inner side of the middle frame 51, and a connecting groove 521 is provided on the inner side of the connecting post 52.

[0045] It also includes an isolation component 6, which includes a support plate 61 disposed on the middle frame 51. One end of the support plate 61 is provided with a connecting protrusion, and the connecting protrusion has a limit groove.

[0046] A horizontal partition 62 is provided above the bottom shell 11. A horizontal groove 621 is provided at one end of the horizontal partition 62. A convex plate 622 is provided above the horizontal partition 62. The convex plate 622 is trapezoidal in shape. Limiting plates 63 are provided on both sides of the horizontal partition 62.

[0047] The transverse groove 621 provided below the transverse partition 62 provides space for the installation of electronic components, preventing it from affecting the internal layout of the meter box.

[0048] Usage process: After the bottom shell 11 is installed with the middle frame 51, align the limiting plate 63 on one side of the transverse partition 62 with the limiting groove on the connecting protrusion at one end of the support plate 61, and press the transverse partition 62 down until the transverse partition 62 contacts the bottom of the bottom shell 11. This allows the electronic components such as switches in the meter box to be installed in separate areas to avoid mutual interference, facilitate identification and operation, and prevent accidental contact during operation or maintenance, thus reducing the risk of electric shock.

[0049] Finally, it should be noted that the methods and devices described in detail above are merely embodiments, and those skilled in the art can modify these embodiments in different ways as long as they do not depart from the scope of this utility model.
