Abstract

Tripod for permanent positioning of highly sensitive devices characterized by being formed by a vertical tubular mast, carrier at its upper end of the device, which when sliding outside another tube of smaller diameter and fixed to a circular base, allows to position the the desired height the aforementioned apparatus. Characterized also by having a vertical groove in the lower end of the mast, which reaches the edge of the tube equipped with lugs welded to its edges and that compressed by a screw that crosses them close the mouth of the tube reducing its diameter and tighten it on the inner tube fixed to the circular base, thus fixing the desired height of the node. Also characterized by having a base or support base formed by three frames with an isosceles triangle shape of angles 120º 30º and 30º that have the vertex of 120º deformed in arc to adapt to the tube of the circular base and which are joined with screws to said base and each other form an equilateral triangle. Also characterized in that said triangular-shaped frames are formed by angular profiles with the lower wing towards the interior of the triangle forming a receptacle in which cement weights fit. Also characterized by the circular base has three pins or sleeves, screwed inside, distanced from the center of the circle and located in radius at 120º and the cement weights have three through slots, by fitting them to the racks, they pass said sleeves. Also characterized by having a large washer which, located on top of the counterweights and screwed to the three threaded sleeves of the circular base by means of screws with a hollow head that can only be operated with a special key, prevents the removal of the counterweights. Also characterized by having three tensioning bars each formed by two profiles to which nuts of opposite thread direction are welded, to which is screwed an asparagus whose ends are also threaded in opposite directions and whose central part is hexagonal section, constituting a thread tensioner. Also characterized by being said tension rods joined with screws for each of its ends to the vertices of the triangle of the base and to the lugs of a fixed flange to the mast that when actuating its tensioner allow to adjust the verticality of said mast and tightening thoroughly provide great rigidity to the tripod.
