[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Example 1: Reference Figure 1-5An underground distribution box is shown, comprising a box body 1. A protective frame 11 is slidably connected to the inner wall of the box body 1. The protective frame 11 is hollow and lightweight. A sliding assembly is provided inside the box body 1. The sliding assembly includes multiple placement slots on the top and bottom sides of both sides of the inner wall of the box body 1, providing positions for the installation and placement of other components. Protrusions 12 are provided on the inner side of the placement slots. The multiple protrusions 12 are made of rubber. Multiple slots 13 that fit the protrusions 12 are provided on the top and bottom sides of the outer side of the protective frame 11. The slots 13 cooperate with the protrusions 12 to ensure that the protective frame 11 can be fixed in a suitable position when needed. A pair of sliders 20 are fixedly connected to the outer side of the protective frame 11. The sliders 20 facilitate the sliding operation of the protective frame 11 inside the box body 1, making its sliding smoother. A sliding groove 15 that fits the sliders 20 is provided on the outer side of the box body 1. 5 provides a sliding track for the slider 20, ensuring the directionality and stability of the sliding of the protective frame 11. A cover plate 2 is provided on the top of the protective frame 11, which can protect the electrical components inside the protective frame 11 and prevent dust, water and other impurities from entering. A pair of fixing blocks 5 are fixedly connected to the outside of the box 1. The fixing blocks 5 are used to fix and support other components. A fixing cylinder 6 is fixedly connected to the outside of the fixing blocks 5. The fixing cylinder 6 passes through the fixing blocks 5 and provides an installation base for subsequent components. It is hollow and convenient for the installation and operation of internal components. A rotating rod 7 is provided on the inside of the fixing cylinder 6. The rotating rod 7 can be adjusted to its position inside the fixing cylinder 6 by rotation. The inner wall of the fixing cylinder 6 is provided with internal threads, and the outer side of the rotating rod 7 is provided with external threads. The fixing cylinder 6 and the rotating rod 7 are threaded together. This threaded connection method can realize the precise movement of the rotating rod 7 inside the fixing cylinder 6. A drill bit 8 is fixedly connected to the outside of the fixing cylinder 6. The drill bit 8 can fix the distribution box to the ground or other installation positions to realize underground installation. A positioning device is fixedly connected to the bottom of the inner wall of the fixing cylinder 6. Block 16, the positioning block 16 provides positioning and support for other components. The end of the spring 17 away from the positioning block 16 is fixedly connected to the tilting block 18. When the tilting block 18 is subjected to a certain external force or the squeezing of the component, it can move and adjust accordingly under the action of the spring 17. The outer side of the multiple tilting blocks 18 is fixedly connected to the extension block 19. The outer side of the fixed cylinder 6 is provided with a slot 14 that matches the extension block 19. The slot 14 provides space and path for the movement of the extension block 19, ensuring that the extension block 19 can operate normally.

[0025] Example 2: Reference Figure 1-5Based on the same concept as Embodiment 1 above, this embodiment further proposes that multiple connecting blocks 9 be provided on the outer side of the housing 1. These connecting blocks 9 can be used to connect other components or structures, expanding the function and application scenarios of the housing 1. Limiting bolts 10 are provided on the outer side of each connecting block 9. Both the housing 1 and the connecting blocks 9 have threaded holes adapted to the limiting bolts 10. Through the cooperation of the limiting bolts 10 and the threaded holes, the connecting blocks 9 can be stably fixed to the housing 1, preventing loosening or displacement, ensuring the reliability and stability of the connection, and making the connection between the housing 1 and external components more reliable. For secure installation, a pair of handles 3 are fixedly connected to the top of the cover plate 2. The handles 3 facilitate the user's opening, closing, or handling of the cover plate 2, making it convenient for inspection, maintenance, or retrieval of items inside the box 1. The top of the cover plate 2 is equipped with bolts 4, and both the cover plate 2 and the box 1 have threaded holes that match the bolts 4. The cooperation between the bolts 4 and the threaded holes can secure the cover plate 2 tightly to the box 1, effectively preventing the cover plate 2 from being opened accidentally and sealing the box 1. This prevents dust, impurities, etc. from entering the box 1 and also ensures the safety and stability of the items inside the box 1.

[0026] The working principle of this utility model is as follows: When the box 1 is buried, the box 1 drives the fixing block 5, fixing cylinder 6, and drill bit 8 into the ground. Twisting the rotating rod 7 and the fixing cylinder 6 causes the threads to move downwards. The downward movement of the rotating rod 7 presses against the inclined surface of the inclined block 18, causing the inclined block 18 to move the extension block 19 outwards, thus locking the extension block 19 into the ground. This ensures that the fixing cylinder 6 is stably locked in the ground, making the placement of the box 1 more stable. When inspecting the distribution box, the limit bolt 10 is unscrewed to release the... Limit the cover plate 2, drag the handle 3 to lift the cover plate 2, the cover plate 2 drives the protective frame 11 to move upward, the protective frame 11 squeezes and deforms the protrusion 12, release the limit on the protective frame 11, so that the protrusion 12 on the top of the box 1 engages with the slot 13 at the bottom of the protective frame 11, limit the protective frame 11, unscrew the bolt 4, release the connection between the cover plate 2 and the protective frame 11, so that when the cover plate 2 is removed, the protective frame 11 shields the box 1, preventing soil clods from sliding into the box 1.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
