Description

Technical Field

[0001] This utility model relates to the field of pre-embedded grounding equipment in building construction, specifically to an installation device for pre-embedded repeated grounding in walls. Background Technology

[0002] Pre-embedded repeated grounding wires in walls are electrical safety devices installed during the structural construction phase of building electrical work. The core principle is to reconnect the neutral wire of the temporary power system to the grounding electrode at critical locations within the wall (such as near electrical equipment or at wiring bends). This reduces the voltage on the equipment casing in case of leakage, minimizes the risk of electric shock from a broken neutral wire, and provides a strong safety barrier for subsequent electrical use. It is an important protective measure for temporary power supply on construction sites.

[0003] Chinese utility model patent CN222381067U discloses a wall-embedded repeated grounding device, comprising: several distribution boxes, each with a grounding sub-wire for grounding; a grounding busbar, with several grounding sub-wires connected to the grounding busbar via cable connectors; a grounding electrode connected to the grounding end of the grounding busbar; and a leakage-proof structure for protecting the connection between the grounding busbar and the grounding electrode from moisture and leakage. The leakage-proof structure also includes a fixing clamp for connecting the grounding busbar and the grounding electrode; the fixing clamp includes a U-shaped connector and a rotating screw; a threaded hole is provided through one side wall of the U-shaped connector, the rotating screw matches the threaded hole, and one end of the rotating screw abuts against the inner wall of the other side wall of the U-shaped connector to clamp the connection between the grounding busbar and the grounding electrode; the other end of the rotating screw is provided with a handle for driving the radial movement of the rotating screw.

[0004] The above solution uses a fixed clamp to hold the grounding electrode and the grounding busbar. However, the fixed clamp requires turning a screw to tighten or loosen it. The fixed clamp is located inside a small cavity, which makes it difficult to hold the grounding busbar and grounding electrode securely. Furthermore, the limited space after clamping the grounding busbar and grounding electrode makes it difficult to apply force when turning the screw. Utility Model Content

[0005] The purpose of this utility model is to address the shortcomings of the above-mentioned technology by proposing an installation device for pre-embedded repeated grounding in walls, which aims to solve the problems of inconvenience in clamping the grounding busbar and grounding body due to limited space in the accommodating cavity, and inconvenience in applying force to lock the clamping after clamping due to limited space.

[0006] This utility model provides an installation device for pre-embedded repeated grounding in a wall. It is installed in a pre-set receiving cavity 1 in the wall and is used to connect the connection ends of the grounding busbar 11 and the connector 12 located in the receiving cavity. The installation device includes an installation frame 2 set in the receiving cavity. An opening and closing mechanism 3 is connected to one end of the installation frame 2 opposite to the opening side of the receiving cavity 1. The opening and closing mechanism 3 is used to allow the grounding busbar 11 and the connector 12 to enter into the installation frame 2 or separate from the installation frame 2. A clamping mechanism 4 is provided at one end of the installation frame 2 near the opening side of the receiving cavity 1 to clamp the connection ends of the grounding busbar 11 and the connector 12.

[0007] Preferably, the mounting frame 2 includes two symmetrically arranged side plates 21, which are connected by a horizontal plate 22.

The other end of the clamping rod 42 is provided with a insertion hole 421 for connecting a tool that drives the clamping rod 42 to rotate.

[0010] The end of the clamping rod 42 extending toward the connecting body 12 has a sleeve connected to an abutment plate 422. The abutment plate 422 is used to increase the contact area between the clamping rod 42 and the connecting body 12.

[0015] To better understand the structure, functional features, and advantages of this utility model, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings: Example: like Figures 1 to 4As shown, this utility model provides an installation device for pre-embedded repeated grounding in a wall. It is installed in a pre-set receiving cavity 1 in the wall and is used to connect the connection ends of the grounding busbar 11 and the connector 12 located within the receiving cavity. The receiving cavity 1 is a square cavity opened in the wall. After connecting the grounding busbar 11 and the connector 12, it is usually necessary to prevent moisture by spraying adhesive or using a leakage-proof structure. The connector 12 is usually made of galvanized flat steel. The installation device is used to lock the connection ends of the grounding busbar 11 and the connector 12 within the receiving cavity, making them connected. The installation device includes a mounting frame 2 disposed within the receiving cavity. An opening and closing mechanism 3 is connected to one end of the mounting frame 2 opposite to the opening side of the receiving cavity 1. The opening and closing mechanism 3 is used to allow the grounding busbar 11 and the connector 12 to enter into or separate from the mounting frame 2. A clamping mechanism 4 is provided at one end of the mounting frame 2 near the opening side of the receiving cavity 1 to clamp the connection ends of the grounding busbar 11 and the connector 12. When the opening and closing mechanism 3 is opened, the opening is inserted into the receiving cavity 1 with the connector 12 facing it, allowing the grounding busbar 11 and the connector 12 to be placed inside the mounting frame 2. The opening and closing mechanism 3 is then closed, and the clamping mechanism 4 is used to press the connection ends of the grounding busbar 11 and the connector 12 within the mounting frame 2 together, thus connecting them. The opening and closing mechanism 3 can be inserted into the receiving cavity with the connector 12 facing it, facilitating the clamping of the grounding busbar 11 and the connector 12 in confined spaces.

[0016] As another embodiment, such as Figure 2 and Figure 3 As shown, the mounting frame 2 of this application includes two symmetrically arranged side plates 21, which are connected by a horizontal plate 22. The side plates 21 extend from the opening side of the receiving cavity 1 towards the inner wall directly opposite the opening side of the receiving cavity 1. One of the side plates 21 is rotatably connected to an opening and closing mechanism 3 at one end near the inner wall of the back side of the receiving cavity 1. A clamping mechanism 4 is connected to the center of the horizontal plate 22. This application divides the inner walls of the receiving cavity 1 into opening sides, with the surface directly opposite the opening side being the inner wall of the back side. The other four surfaces are the two side walls, the top wall, and the bottom wall, respectively. Therefore, the side plate 21 is perpendicular to the inner wall of the back side of the receiving cavity 1, and the horizontal plate 22 and the side plate 21 are connected by welding. The opening and closing mechanism 3 is rotatably connected to one of the side plates 21, and the clamping mechanism 4 is connected to the center of the horizontal plate 22.

[0017] The opening and closing mechanism 3 includes a rotating rod 31. A collar 32 is provided on the side wall of one side plate 21, and one end of the rotating rod 31 is fitted into the collar 32. A slot 211 is provided on the top wall of the other side plate 21, and the end of the rotating rod 31 away from the collar 32 is movably engaged in the slot 211. A swing assembly 33 for assisting the rotation of the rotating rod 31 is connected to the end of the rotating rod 31 away from the slot 211. The middle of the rotating rod is bent to match the shape of the grounding busbar. The collar 32 is horizontal with the side plate 21 and welded to the side of the side plate 21 away from the horizontal plate 22. Alternatively, the collar 32 could be welded to the side of the side plate 21 closer to the horizontal plate 22; however, this application uses a location away from the horizontal plate 22 for easier installation of the swing assembly 33. When it is necessary to place the grounding busbar 11 and the connector 12 into the mounting frame 2 for connection, rotate the rotating rod 31 to open the side of the mounting frame 2 that first extends into the receiving cavity, making it convenient to place the grounding busbar 11 and the connector 12 into the mounting frame 2. Then, rotate the rotating rod 31 in the opposite direction so that the end away from the collar 32 falls into the slot 211. Since the clamping mechanism 4 will push the grounding busbar 11 and the connector 12 towards one side of the rotating rod 31, the rotating rod 31 will not fall out of the slot 211. The middle bend of the rotating rod 31 is because the grounding busbar 11 is a cylinder, so the middle bend can hold the grounding busbar 11 in place at the bend to prevent the grounding busbar 11 from losing contact with the connector 12 when it is shaken.

[0018] The swing assembly 33 includes a swing rod 331. A plurality of connecting blocks 332 are disposed near the end of the swing rod 331 extending out of a collar 32. A plurality of connecting grooves 333 are formed at the end of the swing rod 331 near the swing rod 331, and the connecting blocks 332 are movably inserted into the connecting grooves 333. The end of the swing rod 331 away from the rotating rod 31 is bent. The connecting blocks 332 are welded to the end of the rotating rod 31 away from the retaining groove 211. Multiple connecting blocks 332 can be used; this application uses two symmetrical ones. The sum of the height of the two connecting blocks 332 and the diameter of the swing rod 331 is greater than the inner diameter of the collar 32 to prevent the rotating rod 31 from disengaging from the collar 32. The connecting grooves 333 of the swing rod 331 can hold the connecting blocks 332, so that the rotating rod 331 can rotate when the swing rod 331 rotates. The end of the swing rod 331 away from the rotating rod 31 is bent. This bend can be a multi-bend. This application adopts an L-shaped design for the swing rod 331, which facilitates the rotation of the rotating rod 31 and reduces the space occupied during rotation. The swing rod 331 can also be directly welded to the rotating rod 31. This application provides a connecting block 332 and a connecting groove 333 for welding. When rotating the rotating rod 31, the swing rod 331 can be rotated multiple times to rotate the rotating rod 331 to 90 degrees until the grounding busbar 11 and the connector 12 are both located within the mounting frame 2. This design facilitates use in confined spaces when the grounding busbar 11 and the connector 12 are off-center from the receiving cavity 1.

[0019] As another embodiment, such as Figures 2 to 4 As shown, the clamping mechanism 4 of this application includes a sleeve 41 disposed at the center of the horizontal plate 22. The inner wall of the sleeve 41 is threaded. A clamping rod 42 is inserted into the sleeve 41. The outer wall of the clamping rod 42 is threaded to engage with the threaded inner wall of the sleeve 41. One end of the clamping rod 42 can pass through the sleeve 41 and abut against the connecting body 12. The other end of the clamping rod 42 is provided with a insertion hole 421 for connecting a tool that drives the clamping rod 42 to rotate.

[0020] The end of the clamping rod 42 extending toward the connecting body 12 has a sleeve connected to an abutment plate 422. The abutment plate 422 is used to increase the contact area between the clamping rod 42 and the connecting body 12.

[0021] The insertion hole 421 in this application adopts a prismatic inner wall. In addition, the end of the clamping rod 42 near the opening of the receiving cavity 1 is also prismatic, which facilitates the tightening of tools such as open-end wrenches and adjustable wrenches. When tightening, it is easier to apply force outside the receiving cavity 1 than when tightening inside the receiving cavity 1.

[0022] The above description is merely a preferred embodiment of this utility model and does not constitute any limitation on this utility model. Any person skilled in the art can make many possible variations and modifications to the technical solution of this utility model, or modify it into equivalent embodiments, without departing from the scope of the technical solution of this utility model. Therefore, any modifications, equivalent changes, and alterations made to the above embodiments based on the technology of this utility model without departing from the scope of the technical solution of this utility model shall fall within the protection scope of this technical solution.
