[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0027] The utility model provides Figure 1-3 The underground switch cabinet shown includes an outer protective box 1 and an inner cabinet body 2, wherein the inner cabinet body 2 is arranged in the outer protective box 1, the top end of the outer protective box 1 is open, and a lifting assembly is provided between the inner cabinet body 2 and the outer protective box 1, the inner cabinet body 2 can move up and down in the outer protective box 1 through the lifting assembly, and a sealing plate 17 is provided on the top cover of the outer protective box 1, and the length of the sealing plate 17 is greater than the length of the outer protective box 1.

[0028] When installing the underground switch cabinet, first dig a pit on the ground, then install the outer protection box 1 in the pit, and then install the inner cabinet 2. After burying the outer protection box 1 and the inner cabinet 2 underground, an upper cover plate 17 can be installed on the top of the outer protection box 1. The cover plate 17 can be connected to the top of the outer protection box 1 by bolts, and a handle can be installed on the upper end surface of the cover plate 17 to facilitate lifting it away later.

[0029] In a specific embodiment of the present invention, refer to Figure 2-Figure 3 As shown, there are two groups of lifting components, the two groups of lifting components are symmetrically distributed, and each group of lifting components includes:

[0030] Motor 3, which is installed on one side of the bottom of the outer protective box 1, and is a forward and reverse motor;

[0031] A lead screw 4 is installed at the output end of the motor 3;

[0032] The thread block 13 is connected to the outer wall of the inner cabinet 2 and is sleeved on the outside of the lead screw 4 .

[0033] Specifically, by starting the motor 3, the output end of the motor 3 can be used to drive the lead screw 4 to rotate, thereby driving the inner cabinet 2 connected with the threaded block 13 to move upward or downward, which is relatively convenient.

[0034] Furthermore, a vertical bar 7 is fixed to the outer wall of the inner cabinet 2 , a sliding groove 8 is provided on the outer wall of the vertical bar 7 , and a sliding plate 9 is connected to the inner wall of the outer protective box 1 .

[0035] When the inner cabinet body 2 moves upward or downward, the vertical bar 7 with the slide groove 8 can move linearly along the end of the slide plate 9, thereby ensuring the stability of the inner cabinet body 2 moving up and down.

[0036] See also Figure 2-Figure 4 As shown, a plurality of partitions 10 are provided in the inner cabinet body 2 from top to bottom, a plurality of circular grooves 14 are equidistantly provided on the partitions 10 and along the length direction thereof, a strip groove 15 is provided between two adjacent circular grooves 14, and the inner diameter of the circular groove 14 is larger than the width of the strip groove 15, and a movable partition bar 16 that can move along the length of the strip groove 15 is provided in the strip groove 15.

[0037] Among them, see Figure 4 As shown, an embedding groove 18 is formed on the inner side wall of the strip-shaped groove 15 , and the end of the movable partition bar 16 is slidably fitted in the embedding groove 18 .

[0038] Through the above technical solution:

[0039] The wires connecting the upper and lower layers in the switch cabinet can be limited by passing through the circular groove 14 or the strip groove 15, where the area separated by the movable partition bar 16 is the passing area of ​​different wires, which is conducive to zoning processing, and the position of the movable partition bar 16 is adjustable, so that the size of the wiring area can be flexibly adjusted according to needs. Secondly, wires of the same type can be tied together and then bundled in the circular groove 14, which can avoid confusion of the wiring harness and effectively ensure the neatness and order of the wiring harness. Some wires that need to be checked frequently can directly pass through the strip groove 15.

[0040] In addition, see Figure 2 and Figure 3 As shown, a connecting plate 11 is fixed to the bottom end of the inner cabinet 2, a plurality of elastic columns 6 are connected to the lower end surface of the connecting plate 11, a plurality of elastic columns 6 are commonly connected to the bottom ends of the abutment plate 5, and a wavy elastic plate 12 is provided on the lower end surface of the abutment plate 5.

[0041] Through the above technical solution:

[0042] When a failure occurs and causes the inner cabinet 2 to drop, when the bottom end of the inner cabinet 2 contacts the outer protective box 1, the wavy elastic plate 12 first deforms to initially buffer the pressure and disperse the pressure in multiple directions. Then, the plate 5 squeezes the elastic column 6. The elastic force generated by the pressure on the elastic column 6 can further buffer the vertical pressure, thereby improving the protection of the inner cabinet 2 and reducing the occurrence of damage to internal equipment.
