Description

Technical Field

[0001] This application relates to the field of lightning protection grounding technology, and in particular to a pre-embedded grounding structure. Background Technology

[0002] Currently, grounding structures are typically required in facilities such as factories and residential buildings to facilitate quick connection of equipment to the grounding wire. Traditional grounding structures usually expose the grounding conductor outside the building, which not only affects aesthetics but also makes it difficult to protect the grounding point, causing inconvenience for subsequent equipment grounding. Furthermore, it poses a tripping hazard to pedestrians.

[0003] For example, the utility model patent with announcement number CN207149717U discloses a wall-mounted concealed grounding terminal box and an anti-static grounding terminal box. Although the housing is embedded in the wall, the grounding terminal, i.e. the grounding lead-out conductor, is exposed outside the wall and protected by the terminal cap. However, the grounding terminal exposed outside the wall will make the wall surface uneven, affecting the aesthetics, and cannot provide comprehensive protection for the grounding terminal exposed outside the housing. In addition, it is easy to collide with moving people or equipment, posing a safety hazard. Utility Model Content

[0004] Therefore, it is necessary to provide a pre-embedded grounding structure, the specific technical solution of which is as follows.

[0005] An embedded grounding structure includes:

[0006] An embedded component includes a sleeve and a leveling plate, wherein the leveling plate is connected to the end of the sleeve; a supporting lug is connected to the inner wall of the sleeve.

[0007] A grounding terminal includes a terminal body and an end plate connected to the end of the terminal body; the terminal body is provided with a grounding hole for connecting to external equipment;

[0008] A pad abuts against a supporting ear plate; the pad is provided with a through hole for accommodating the terminal body;

[0009] A pressure plate is connected to a pad plate, and the pad plate and the pressure plate clamp the end plate; the pressure plate is provided with an exposure hole to expose the grounding hole; the height of the pressure plate does not exceed the outer surface of the leveling plate.

[0010] Specifically, the sleeve is embedded in the building, and the leveling plate is flush with the building surface.

[0011] Specifically, the sleeve has a retaining plate on its side, which extends outward along the radial direction of the sleeve.

[0012] Specifically, the sleeve end face is provided with a bearing portion, and the bearing portion and the leveling plate form a stepped shape; the pressure plate presses on the bearing portion.

[0013] Specifically, it also includes a cover plate that covers the pressure plate.

[0014] Specifically, the outer diameter of the pressure plate is smaller than the inner diameter of the finding plate, so that an annular gap is formed between the pressure plate and the finding plate; the cover plate includes a top plate and a surrounding plate, the top plate covers the pressure plate, and the surrounding plate is inserted into the annular gap.

[0015] Specifically, the pressure plate is bolted to the bearing part.

[0016] Specifically, the pad and the pressure plate are connected by a first connecting bolt, and the support ear plate is provided with a positioning hole to accommodate the passage of the first connecting bolt.

[0017] Specifically, a limiting plate is provided between the terminal body and the end plate; the pad is provided with a limiting groove to accommodate the passage of the limiting plate.

[0018] Specifically, the grounding hole is a threaded hole.

[0019] Beneficial effects: The pre-embedded grounding structure provided by this utility model ensures that the leveling plate is level with the building surface during pre-embedding, and the grounding terminal is located inside the pre-embedded part. It is connected to the external equipment to be grounded through the grounding hole, so that there is no protrusion on the building surface, which not only ensures the aesthetics of the building surface, but also avoids the grounding terminal from colliding with moving personnel or equipment, eliminating safety hazards; in addition, all the grounding terminals are located inside the pre-embedded part, which also forms a comprehensive protection for the grounding terminals.

[0039] Example

[0040] Reference Figure 1 As shown, this embodiment provides a pre-embedded grounding structure, which includes an embedded part 1, a grounding terminal 2, a pad 3, and a pressure plate 4. (Refer to...) Figure 4 As shown, the embedded part 1 includes a sleeve 11 and a leveling plate 12. The leveling plate 12 is connected to the end of the sleeve 11. When the embedded part 1 is embedded, the surface of the leveling plate 12 is leveled with the surface of the building. The sleeve 11 has two opposingly arranged support lugs 13 connected inside.

[0041] Reference Figure 5As shown, the grounding terminal 2 includes a terminal body 21 and an end plate 22 connected to the end of the terminal body 21. The outer diameter of the end plate 22 is larger than the outer diameter of the terminal body 21. The terminal body 21 is provided with a grounding hole 23 for connecting to external equipment. In use, the terminal body 21 is connected to a grounding wire, the grounding wire is spirally wound inside the sleeve 11, and the external equipment is inserted into the grounding hole 23, thereby forming a ground.

[0042] Continue to refer to Figure 1 As shown, the pad 3 abuts against the supporting ear plate 13, and the supporting ear plate 13 supports the pad 3. The pad 3 has a through hole 31 for accommodating the terminal body 21, the diameter of which is smaller than the outer diameter of the end plate 22, so that the end plate 22 presses on the pad 3. The pressure plate 4 presses on the end plate 22, and the pressure plate 4 is connected to the pad 3, so that the pad 3 and the pressure plate 4 clamp the end plate 22, thereby forming a whole with the pad 3, the grounding terminal 2, and the pressure plate 4. Figure 3 As shown, in actual construction, the pad 3, grounding terminal 2, and pressure plate 4 are usually connected together to form a whole before use. The pressure plate 4 is provided with an exposure hole 41 that exposes the grounding hole 23, that is, the diameter of the exposure hole 41 is larger than the diameter of the grounding hole 23, which facilitates the connection of external equipment to the grounding hole 23. The horizontal height of the pressure plate 4 exceeds the outer surface of the leveling plate 12, that is, the pressure plate 4 is completely located inside the embedded part 1, to avoid the pressure plate 4 protruding outward from the leveling plate 12, which would affect the aesthetics of the building surface and avoid safety hazards.

[0043] The embedded grounding structure provided in this embodiment is leveled with the building surface during the pre-embedding process. The grounding terminal 2 is located inside the embedded part 1 and is connected to the external equipment to be grounded through the grounding hole 23. This ensures that there are no protrusions on the building surface, thus guaranteeing the aesthetics of the building surface and preventing the grounding terminal 2 from colliding with moving personnel or equipment, eliminating safety hazards. In addition, all the grounding terminals 2 are located inside the embedded part 1, which also provides comprehensive protection for the grounding terminals 2.

[0044] Specifically, the pre-embedded sleeve 11 is pre-embedded inside the building, and the leveling plate 12 is flush with the building surface, thereby ensuring the aesthetics of the building surface.

[0045] Specifically, the sleeve 11 is provided with a retaining plate 14 on its side, which extends outward from the sleeve 11 along the radial direction of the tower. By providing the retaining plate 14, the sleeve 11 is tightly integrated with the building after being embedded, preventing the sleeve 11 from rotating and separating from the building.

[0046] Specifically, refer to Figure 4As shown, the sleeve 11 has a bearing portion 15 at its end, forming a stepped shape between the bearing portion 15 and the leveling plate 12. The pressure plate 4 presses on the bearing portion 15, increasing the bearing strength of the pressure plate 4 and preventing it from being entirely compressed by the supporting ear plate 13. This ensures that the pressure plate 4 maintains structural reliability even under certain external pressure. Additionally, a connecting threaded hole 16 can be provided on the bearing portion 15, allowing the pressure plate 4 to be bolted to the bearing portion 15 using a second connecting bolt. This prevents relative movement or rotation between the grounding terminal 2 and the embedded part 1, ensuring the stability of the grounding terminal 2 after installation.

[0047] Specifically, continue to refer to Figure 1 As shown, the embedded grounding structure also includes a cover plate 5. The cover plate 5 covers the pressure plate 4, and when the grounding terminal 2 is not connected to the equipment, the cover plate 5 protects the grounding terminal 2. (Refer to...) Figure 6 As shown, the outer diameter of the pressure plate 4 is smaller than the inner diameter of the leveling plate 12, forming an annular gap 17 between the pressure plate 4 and the leveling plate 12. The cover plate 5 includes a top plate 51 and a surrounding plate 52. The top plate 51 covers the pressure plate 4, and the surrounding plate 52 is inserted into the annular gap 17. This facilitates the placement of the cover plate 5 and prevents displacement. It also ensures that the cover plate 5 is flush with the building surface, thus guaranteeing the aesthetics of the building surface. When it is necessary to remove the cover plate 5, a flathead screwdriver or a metal sheet can be inserted into the gap between the end plate 22 and the leveling plate 12 to pry the cover plate 5 out.

[0048] Specifically, the pad 3 and the pressure plate 4 are provided with corresponding connecting holes, and the support ear plate 13 is provided with a positioning hole 18 aligned with the connecting hole. The pad 3 and the pressure plate 4 are connected by a first connecting bolt. During installation, the first connecting bolt is aligned with the positioning hole 18 and then inserted into the positioning hole 18 to facilitate the positioning of the pad 3, the pressure plate 4 and the support ear plate 13.

[0049] Specifically, continue to refer to Figure 5 As shown, a limiting plate 24 is provided between the terminal body 21 and the end plate 22; the pad 3 is provided with a limiting groove 32 to accommodate the limiting plate 24. The limiting groove 32 is used to restrict the rotation of the terminal body 21 and ensure the stability of the terminal body 21 after installation.

[0050] Specifically, the grounding hole 23 is a threaded hole, which connects the external device to the grounding terminal 2 by thread, thereby ensuring the stability of the connection.

[0051] How to use:

[0052] Embedded part 1 is embedded into the building, and leveling plate 12 is made level with the building surface. A spiral grounding wire is arranged inside sleeve 11. The connected pad 3, grounding terminal 2, and pressure plate 4 are placed on support ear plate 13, and the first connecting bolt is positioned by passing through positioning hole 18; the pressure plate 4 and bearing part 15 are connected by second connecting bolt. Finally, cover plate 5 is put on. When grounding is required, cover plate 5 is removed to connect the equipment to grounding hole 23 on grounding terminal 2 to form grounding.

[0053] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0054] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
