Technical Field
[0001] The invention belongs to the technical field of grounding clamps, and in particular relates to a replaceable grounding clamp assembly structure. Background Art
[0002] Although the energy of static electricity is not large, it is easy to discharge due to its high voltage. When a charged body approaches an uncharged body or an object with low static potential, if the potential difference reaches more than 300V, spark discharge will occur. If the spark energy has reached the minimum ignition energy of the surrounding combustibles, and the concentration of the combustibles in the air reaches the explosion limit, combustion or explosion will occur immediately. In the fields of petrochemicals, medicine, paints, and coatings, in order to eliminate the hazards of static electricity accumulation generated during the storage and transportation of flammable and explosive liquids, different types of static electricity grounding clamps are needed, equipped with different connecting cables, to ground securely to release static electricity and ensure safe operation. A high-strength alloy ejector is set at the top of the static electricity grounding clamp to break paint and remove rust, ensuring reliable grounding of the vehicle body and container; the clamp body has a built-in constant force spring, and the elastic force remains unchanged after 30,000 pinchings, ensuring sufficient clamping force. Ensure that the clamp can maintain low resistance contact with the equipment and ensure that the clamp can be firmly connected to the vibration equipment without slipping.
[0003] When a power outage or circuit maintenance is carried out, it is necessary to perform the operation of hanging a ground wire, the purpose of which is to connect the equipment to the earth with a temporary ground wire, introduce current into the ground, avoid current accumulation inside the equipment, and thus reduce the occurrence of equipment failures.

When in use, the screw rod 23 moves vertically up and down during rotation. When the screw rod 23 moves upward, it drives the first guide protrusion, the second guide protrusion and the third guide protrusion to move upward in the front guide groove 26, the right guide groove 27 and the rear guide groove respectively, so as to realize stable and smooth movement of the lower clamp 25.
[0034] For better effect, the upper surface of the lower clamp 25 is provided with an arc-shaped opening, and a plurality of lower convex strips 28 are fixedly provided on the upper surface of the arc-shaped opening. The lower clamp 25 comprises a middle part, a front convex part 29 is fixedly provided at the front end of the middle part, and a rear convex part is fixedly provided at the rear end of the middle part; the first guide protrusion is fixedly connected to the rear side wall of the front convex part 29, the second guide protrusion is fixedly connected to the left side wall of the middle part, and the third guide protrusion is fixedly connected to the front side wall of the rear convex part.
