Abstract
The invention relates to a fast combined connection type grounding grid. The fast combined connection type grounding grid includes grounding strips and grounding adapting connectors which are connected with together through screw threads; the grounding strips can be connected with the grounding adapting connectors fast in a dug grounding grid groove; except two ends of each grounding strip, the whole middle part of the grounding strip is rolled to form a flat bar, and the two ends of the grounding strip are squeezed to form round rods; the round rods at two ends of each grounding strips are directly rolled so as to form two opposite screw threads, wherein one screw thread winds leftwards, and the other screw thread winds rightwards; and two joints of each cross-shaped or special-shaped grounding adapting connector at one linear direction are machined into two leftwards-winding screw threads, and two joins of the grounding adapting connector along the other linear direction are machined into two rightwards-winding screw threads. When the grounding grid is installed, the grounding strip can be rotated, so that two grounding adapting connectors at two ends of the grounding strip can be rotated and tightly screwed on the grounding strip simultaneously, and other grounding strips and grounding adapting connectors are connected in the same manner, and therefore, the whole grounding grid can be formed. With the above technical scheme of the invention adopted, the fast combined connection type grounding grid has the advantages of simple structure, reliable connection, convenient installation and operation, easiness in quality management control and control, large contact area with the ground, low grounding resistance and reliable and stable operation.
