Description

Technical Field

[0001] The utility model relates to the technical field of ground wires, in particular to an adjustable ground wire. Background Art

[0002] A grounding wire is a conductor used to connect electrical equipment or circuits to the ground. It is usually used for safety purposes to prevent personal injury or fire when electrical equipment leaks or is overloaded. The main function of the grounding wire is to introduce current into the ground so that the charge in the circuit can be safely released. An adjustable grounding wire is a cable used to connect electrical equipment to the ground. The length can be adjusted as needed. This cable is usually used to ensure good grounding of the equipment to prevent static electricity accumulation or electrical failures. It can adapt to grounding requirements at different heights or distances by adjusting the length to ensure an effective grounding connection.

[0003] After the ground wire is connected to the ground, the adjustable ground wire cannot limit the ground connection position, causing the ground wire connection end to be easily pulled, affecting the stability of the connection. Utility Model Content

[0004] The purpose of the utility model is to provide an adjustable grounding wire, which has the advantages of fixing the take-up roller after the grounding wire body on the take-up roller is paid out to a suitable length, and applying a clamping force to the paid-out grounding wire body to prevent the grounding wire from being pulled and becoming loose, thereby solving the problem that the adjustable grounding wire cannot limit the grounding wire.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable grounding wire, including a retaining frame, bearings 2 are embedded and installed on both sides of the retaining frame, and the inner rings of the two bearings 2 are fixedly installed with connecting rods, and the two connecting rods are installed with wire-taking rollers at opposite ends, and the grounding wire body is rolled up on the wire-taking roller, and a connecting plate is installed at one end of the connecting rod on one side of the retaining frame, and two springs are symmetrically installed on the side of the connecting plate opposite to the retaining frame, and movable plates are installed at the ends of the two springs facing away from the connecting plate, and bearings 1 are installed on both sides of the inner part of the retaining frame below the wire-taking roller, and the inner rings of the two bearings 1 are fixedly installed with fixing rods, and the opposite ends of the two fixing rods are welded with fixing plates, and the two fixing plates are provided with screw holes, and the inner walls of the two screw holes are threadedly connected with screws, and clamping rings are installed at the opposite ends of the two screws.

[0006] When using the adjustable grounding wire in the technical solution, the fixing frame is fixed to the ground or the bearing structure through the fixing holes of the fixing frame using bolts and other tools, and the two movable rods are pulled by the handle. The two movable rods drive the two movable plates to leave the sides of the retaining frame, and the two movable plates squeeze the connecting plates through the springs. At the same time, the connecting plates are rotated, and the connecting plates drive the connecting rods to rotate, and the connecting rods drive the take-up rollers to rotate and release the wire. After the grounding wire body is adjusted outward to a suitable length, the handle is released, and the two springs push the two movable plates to contact the sides of the retaining frame to fix the position of the connecting plates. The grounding end of the grounding wire body is passed through the middle of the two clamping rings to connect to the grounding structure, and two hand wheels are used to rotate the two screws. The two screws rotate and move in the screw holes of the two fixing plates, and the two screws push the two clamping rings to move to clamp and fix the grounding wire body.

[0007] Preferably, a movable rod is installed on the side of the two movable plates away from the retaining frame, the connecting plate is symmetrically provided with two movable holes, and the ends of the two movable rods away from the two movable plates pass through the two movable holes respectively. The two movable rods limit the two movable plates and restrict the moving directions of the two movable plates.

[0008] Preferably, a handle is installed at one end of the two movable rods away from the two movable plates. The handle can be used to pull the two movable rods, and the two movable rods drive the two movable plates to move.

[0009] Preferably, hand wheels are installed at the ends of the two screw rods that are away from each other. The two screw rods can be rotated using the two hand wheels.

[0010] Preferably, the outer diameters of the two hand wheels are larger than the inner diameters of the two screw holes. The hand wheels prevent the screw rods from falling out of the screw holes.

[0011] Preferably, a distance is left between the two movable plates and the second bearing on the side of the retainer. When the two movable plates move, they will not interfere with the second bearing and can completely contact the side of the retainer.

[0012] Preferably, a fixing frame is welded at the bottom of the retaining frame, and fixing holes are provided in a rectangular array at the bottom of the fixing frame. The fixing frame is fixed to the ground or the bearing structure by using tools such as bolts through the fixing holes of the fixing frame.

[0013] Preferably, a distance is left between the take-up roller and the bottom end of the inner part of the retaining frame so that the take-up roller will not interfere with the retaining frame when rotating.

[0014] Compared with the prior art, the beneficial effects of the utility model are:

[0015] The utility model provides a spring and a clamping ring, and a connecting plate drives the take-up roller to pay out the wound ground wire body through the connecting plate. After the ground wire body is adjusted to a suitable length, the two springs rely on their own springs to push the two movable plates to contact the side surfaces of the retaining frame, fix the position of the connecting plate, and prevent the take-up roller from rotating. The two screws push the two clamping rings to move and clamp and fix a section of the grounded ground wire body, so that after the ground wire body on the take-up roller is paid out to a suitable length, the take-up roller is fixed, and at the same time a clamping force is applied to the paid-out ground wire body to prevent the ground wire from being pulled and loosened.
