Description

Technical Field

[0001] This utility model relates to the field of grounding protection technology, specifically an electrical installation grounding protection device. Background Technology

[0002] Grounding protection refers to a protective wiring method that reliably connects the metal parts of electrical appliances (i.e., the metal structural parts insulated from the live parts) that are normally not energized but may become energized after the insulation material is damaged or under other circumstances, to a grounding electrode using a conductor.

[0003] Electrical equipment generates vibrations during operation, and prolonged use may cause the bolts or joints at the grounding wire connection to loosen. A loose grounding wire may result in unreliable grounding, failing to effectively conduct current to the ground. When equipment malfunctions, it cannot provide sufficient grounding protection, increasing the risk of electric shock or fire and posing a safety hazard.

[0004] Therefore, those skilled in the art have provided an electrical installation grounding protection device to solve the problems mentioned in the background art. Utility Model Content

The wire harness installation mechanism is provided on the inner side wall of the electrical box, and the wire harness fixing mechanism is provided at the bottom of the electrical box. Fixed boxes are fixedly connected to both the left and right ends of the support base. Each fixed box has a cavity, and a movable plate is slidably connected to each cavity. A threaded rod is fixedly connected to the top of each movable plate, and the threaded rod passes through the fixed box and is threadedly connected to the fixed box. Two sets of fixing spikes are fixedly connected to the bottom of each movable plate.

[0008] As a further embodiment of this utility model: the front end of the electrical box is hinged with a door, and a fixing block is fixedly connected to the inner wall of one end of the electrical box. Magnetic grooves are provided on both the left and right ends of the fixing block. Insertion magnetic blocks are magnetically engaged in the magnetic grooves. Insertion blocks are fixedly connected to the upper ends of the two sets of insertion magnetic blocks. Wire grooves are provided in both the insertion blocks and the fixing blocks.

[0009] As a further scheme of the utility model: the inside bottom end of the electrical box is embedded with a fixing disc, limit grooves are formed at the central position of the fixing disc and the central position of the supporting seat, two groups of limit grooves are arranged in coincidence, a driven gear is rotatably connected to the central position of the inside of the fixing disc, a driving gear is rotatably connected to one end of the driven gear, and a micro motor is fixedly connected to the upper end of the driving gear and fixedly connected to the inner wall of the fixing disc at the other end.

[0010] As a further scheme of the utility model: a plurality of clamping grooves are formed in the driven gear, clamping rods are slidably clamped in the clamping grooves, hinged arc-shaped rods are hinged to the ends of the clamping rods, abutting blocks are hinged to the other ends of the hinged arc-shaped rods, the abutting blocks are slidably connected with the limit grooves of the fixing disc and slidably connected with adjacent abutting blocks.

[0011] As a further scheme of the utility model: the magnetic attraction groove and the plug-in magnetic attraction block are arranged to be magnetically attracted to each other.

[0012] As a further scheme of the utility model: the driven gear is engaged with the driving gear.

[0013] Compared with the prior art, the utility model has the advantages that:

[0014] Because the wire harness mounting mechanism is arranged, the fixed thorn is firmly fixed to the ground by the horizontal movement of the threaded rod and the downward pushing of the moving plate, so that the displacement or shaking of the supporting seat and the electrical box caused by external force impact or vibration during use is effectively prevented, and the loosening of the grounding wire is avoided.

[0015] The first end of the grounding wire is firmly fixed by the magnetic attraction force between the magnetic attraction groove and the plug-in magnetic attraction block, so that the loosening or separation of the grounding wire from the ground due to vibration or external force is avoided, and the stability of the grounding wire is improved.

[0016] Because the wire harness fixing mechanism is arranged, the transmission of the micro motor driving the driving gear and the driven gear enables the clamping rod to move in the clamping groove, and the hinged arc-shaped rod and the abutting blocks at the ends thereof can be fixed to the grounding wire according to the limit and arc-shaped stroke of the clamping groove, so that the grounding wire is stably fixed at the fixed position for a long time, the loosening or separation of the grounding wire from the ground due to shaking is prevented, the reliability of grounding is ensured, the electrical safety problem caused by poor grounding is avoided, and the safety hidden danger caused by the separation of the grounding wire from the electrical box or the ground after a long time of use of the equipment is ensured.
