The telescopic component includes a plurality of telescopic cylinders 12 fixedly arranged at the bottom of the inner wall of the buried box 1 and a spring 13 and a telescopic rod 14 inside the telescopic cylinder 12. The top of the telescopic cylinder 12 is an open structure, and the telescopic rod 14 is inserted into the top opening of the telescopic cylinder 12. The upper and lower ends of the spring 13 respectively resist the telescopic rod 14 and the telescopic cylinder 12, and a movable plate 9 is fixed on the top of the telescopic rod 14.

[0037] In this embodiment, the underground box 1 is an overall square structure. The underground box 1 is composed of a box body and a boss. The box body is located inside the ground, and the boss is located outside the ground and fits with the ground. The boss is annularly fixed at the outer edge of the upper end surface of the buried box 1. The telescopic component provided inside the buried box 1 can adjust the height of the control switch body 6. The telescopic component adopts multiple components arranged at the bottom of the movable plate 9 and the inner wall of the buried box 1. The telescopic components are arranged horizontally or vertically inside the buried box 1. Multiple telescopic components are arranged at intervals, and multiple telescopic components are symmetrically arranged around the center of the buried box 1. The telescopic component is composed of a telescopic cylinder 12 and a spring 13 and a telescopic rod 14 inside the telescopic cylinder 12. The top of the spring 13 is connected to the telescopic rod 14, and when the control switch body 6 is inside the buried box 1, the spring 13 is in a compressed state. After opening the sealing cover 2, the spring 13 is retracted to push the control switch body 6 out of the buried box 1 to the outside, which is convenient for the staff to use.

[0038] On the basis of the above embodiment, in this embodiment, a screw hole is opened on the upper end surface of the movable plate 9, a mounting block is fixed on the lower end surface of the control switch body 6, a bolt 8 is inserted into the upper end surface of the mounting block, and the bottom of the bolt 8 is inserted into the screw hole.

[0039] In this embodiment, when the control switch body 6 needs to be installed, the control switch body 6 is installed on the mounting plate 7, and the mounting plate 7 is installed on the movable plate 9 by bolts 8, so that the height of the control switch body 6 can be adjusted by the telescopic assembly, which is convenient for installation and can also be easily disassembled when disassembly is required.

[0043] In this embodiment, the sealing cover 2 is used to seal the opening of the buried box 1. The convex structure can seal the opening of the buried box 1 twice. The larger end of the sealing cover 2 is directly larger than the buried box 1 and covers the opening of the buried box 1 as a whole to prevent rainwater from entering the interior of the buried box 1. The sealing member adopts a rubber structure to further prevent rainwater from entering the interior of the buried box 1.

[0044] On the basis of the above-mentioned embodiment, in this embodiment, the upper end surface of the buried box 1 is connected with a hook 3 through a damping hinge, the hook 3 is located on one side of the sealing cover 2, and the other end of the hook 3 is attached to the upper end surface of the sealing cover 2.

[0045] In this embodiment, one end of the hook 3 is connected by a damping hinge so that the hook 3 can rotate, and the other end is pressed on the upper end surface of the sealing cover 2. Under the action of the damping hinge, the hook 3 has a force to press the sealing cover 2 to prevent the sealing cover 2 from moving.

[0046] Based on the above embodiments, in this embodiment, the lower end surface of the sealing cover 2 is connected to a pressing rod 4 via a damping hinge, the lower end surface of the pressing rod 4 is connected to a pressing block 5 via a damping hinge, and the lower end surface of the pressing block 5 is in contact with the control switch body 6.

[0047] In this embodiment, the pressing rod 4 and the pressing block 5 on the lower end surface of the sealing cover 2 press the control switch body 6 to prevent the control switch body 6 from moving.

[0048] On the basis of the above-mentioned embodiment, in this embodiment, a wiring hole is opened on one side of the underground box 1, and the wires of the control switch body 6 are arranged inside the wiring hole.

[0049] When using the utility model: after opening the sealing cover 2, the compressed spring 13 is extended and retracted to push the movable rod, and the movable rod pushes the movable plate 9, so that the movable plate 9 drives the control switch body 6 to move upward, so that the control switch body 6 moves from the inside of the buried box 1 to the outside. After use, when closing the sealing cover 2, the pressing rod 4 on the sealing cover 2 drives the pressing block 5 to press the control switch body 6, so that the control switch body 6 returns to the initial position.
