Description

Technical Field

[0001] The utility model relates to the technical field of ground wire connection accessories, in particular to a mobile grounding box. Background Art

[0002] A ground wire is a wire that is connected to the ground, the outer shell, or a reference potential of zero in an electrical system or electronic device. Generally, on an electrical appliance, the ground wire is connected to the outer shell to prevent electric shock accidents caused by the electrification of the outer shell due to internal insulation damage of the appliance. The ground wire is the abbreviation of the grounding device. The ground wire is further divided into working grounding and safety grounding. The protective grounding adopted to prevent people from getting an electric shock when using household appliances and office electronic devices is a kind of safety grounding wire. However, when the existing on-site operation equipment is grounded, it is necessary to drive iron pins into the ground, one for each equipment. This not only damages the road surface and has a large workload, but also has the risk of piercing water pipes and cables. Therefore, an auxiliary tool for ground wire connection is needed to avoid driving iron pins frequently and damaging the road surface. Content of the Utility Model

[0003] Aiming at the deficiencies of the prior art, the utility model provides a mobile grounding box to solve the problems that when the existing equipment is grounded, it is necessary to drive iron pins into the ground, one for each equipment, which not only damages the road surface and has a large workload, but also has the risk of piercing water pipes and cables.

[0004] To achieve the above purposes, the utility model is realized through the following technical solutions: A mobile grounding box includes a box body with an opening at the front side. Inside the box body, there are several U-shaped copper bars. The several copper bars are connected in series with each other, and one of the two ends of one of them is connected with a ground wire. At the top of the copper bar, there are several equally spaced connection holes. On both sides of the box body, there are retractable support legs.

[0005] Preferably, on both sides of the box body, there is a winding component for winding the ground wire. The winding component includes a bracket fixedly connected to the side plate of the box body. The bracket is provided with a horizontal transmission rod through a fixed bearing. Both ends of the transmission rod are fixedly connected with winding wheels. The ground wire is wound on the winding wheels; a rotating handle is arranged on the winding wheels.

[0006] Preferably, fixing grooves and traction grooves are respectively formed at both ends of the winding wheel. The end of the transmission rod is inserted and fixed in the fixing groove. A through hole communicating with the arc surface of the winding wheel is formed inside the traction groove. One end of the grounding wire is fixedly connected to both ends of the copper bar through an adapter piece. The other end of the grounding wire sequentially passes through the traction groove and the through hole and is wound around the surface of the winding wheel. As a preferred embodiment, the part of the grounding wire passing through the through hole is fixed inside the through hole by means of adhesion or screw fixation, thereby preventing the winding wheel from pulling the grounding wire off the adapter piece. At the same time, the distance from the position fixed in the through hole to the position of the adapter piece is long enough. When the winding wheel rotates, it will drive the grounding wire in the traction groove to rotate. When the grounding wire is long enough, it can relieve the self-twisting degree of the grounding wire and prevent it from being pulled off the adapter piece due to twisting. A fixing clip is provided at the end of the grounding wire away from the adapter piece. With such a setting, when the winding wheel rotates, the traction groove can be used to make the grounding wire pass through the through hole from the central axis position of the winding wheel and wind around the surface of the winding wheel. Then, when the winding wheel rotates, one end of the grounding wire close to the adapter piece rotates in the traction groove, preventing the grounding wire at this end from winding around the winding wheel and facilitating the storage of the other end of the grounding wire.

[0007] Preferably, two storage grooves penetrating the bottom of the box body are respectively formed on both sides of the box body. The bottom of the storage groove is provided with support legs through a movable connection shaft. Two positioning holes are arranged on the support legs, and the two positioning holes are distributed on both sides of the movable connection shaft. With such a setting, the support legs can rotate around the movable connection shaft through the movable connection shaft. At the same time, by respectively inserting and matching the bolts with the two positioning holes, the support legs can be fixed at the bottom of the storage groove or the box body.

[0008] Preferably, a rubber layer is arranged inside the box body. By arranging the rubber layer, the equipment wiring terminals inside the box body can be isolated from the surface of the box body, preventing current from passing through the surface of the box body and improving safety performance.

[0009] Preferably, a handle is arranged on the top of the box body. By arranging the handle, it is convenient to lift and carry the box body.

[0010] Preferably, a movable door is installed at the front opening of the box body. A plurality of wire troughs are formed on the movable door, and the wire troughs respectively correspond and cooperate with the winding wheel and the connection hole. By arranging the wire troughs, it is convenient for the grounding wire and the grounding wire of the equipment to be drawn out of the box body.

[0011] The utility model provides a mobile grounding box, which has the following beneficial effects:

[0012] 1. The utility model connects the grounding wire to the grounding flat iron through a copper bar, and then connects the copper bar to the grounding wire of the equipment, avoiding driving iron pins one by one for multiple operating equipment, avoiding road damage, and avoiding the risk of piercing pipelines and cables. At the same time, the workload is greatly reduced, and manpower and material resources are saved.

[0013] 2. The utility model can quickly wind up the grounding wire through the winding component, avoiding the grounding wire being randomly wound together and making the interior of the device neater. BRIEF DESCRIPTION OF THE DRAWINGS

[0025] During specific use, connect the grounding wire 4 to the grounding flat iron, then connect the copper bar 2 to the grounding wire 4 of the equipment. Thus, the working equipment is connected to the grounding flat iron through the copper bar 2, realizing the grounding work of the working equipment, avoiding the need to drive iron rods one by one for multiple working equipment, avoiding road damage, and avoiding the risk of piercing pipelines. At the same time, the workload is greatly reduced, saving manpower and material resources.

[0026] Embodiment 2

[0027] Please refer to Figures 3 - 4 , on the outer side of the box body 1, there is a winding component 5 for winding the grounding wire 4. The winding component 5 includes a bracket fixedly connected to the side plate of the box body 1. The bracket is installed with a horizontal transmission rod through a fixed bearing.
