Resumen
Non-rotating locking system for use in a tribrach platform used as a support for topographic measuring instruments, characterized in that it comprises: - a blocking element between the tribrach (1) and the tribrach adapter (2) which in turn comprises the following parts: - a main body (6) with a frustoconical configuration - a threaded cylindrical part (7) at one end - an initial part or neck (5), cylindrical in shape, incorporating 2 plates (4) that allow to increase the adjustment pressure manually - a frustoconical-shaped hole (8), located on one side of the tribrach (1), into which the blocking element is inserted, the maximum diameter of which coincides with the maximum diameter of the main body of the blocking element (6) - a threaded hole (9), located on one side of the tribrach adapter (2) and arranged to coincide with the frustoconical hole (8), in which the threaded cylindrical part of the blocking element is screwed (7) ).
