Description

Telescopic combined prism Technical Field The utility model relates to the field of special prisms for surveying and mapping total stations, in particular to a telescopic combined prism. Background The total station, namely the total station type electronic distance meter, is a high-technology measuring instrument integrating light, machine and electricity, and is a surveying instrument system integrating the functions of measuring horizontal angle, vertical angle, distance (inclined distance and flat distance) and height difference. Compared with an optical theodolite, the electronic theodolite changes the optical dial into a photoelectric scanning dial, and replaces manual optical micrometer reading with automatic recording and displaying reading, so that the angle measuring operation is simplified, and reading errors can be avoided. The total station is called because it can complete all the measurement work on the station by setting the instrument at one time. The method is widely applied to the fields of precision engineering measurement or deformation monitoring such as ground large-scale building and underground tunnel construction. The total station generally works by emitting a beam to the prism through a laser or red line emitter and then reflecting back through an inverse prism. The computer inside the total station calculates the coordinates of the target according to the angle and distance of the light rays and stores the data in the memory. By constantly measuring, three-dimensional coordinates of the object in space can be obtained. According to the prism assembly of the total station disclosed in the patent 202322230420.6, the total station comprises a support, a fixed frame is arranged at the upper end of the support, a prism body is arranged in the fixed frame, the prism body is rotationally connected with the fixed frame, a movable platform is arranged on one side of the fixed frame and is connected with a lens seat of the prism body, a collimator is arranged on one side of the movable platform, which is far away from the fixed frame, the axis of the collimator is parallel to the axis of the prism body, and the collimator is detachably and fixedly connected with the movable platform. The prism assembly can enable a measurer at the position of the prism assembly to independently finish the work task of adjusting the angle and the position of the prism, thereby saving the trouble of communicating with the measurer at the total station, effectively improving the measuring working face and further improving the measuring efficiency. But in the use, traditional prism subassembly, when using the total powerstation to measure, because total powerstation and prism position sight are sheltered from, can't accomplish the measurement, simultaneously, because single prism angle is fixed, lead to it to be restricted by measuring range, can not satisfy diversified measurement demand, reduced single prism's suitability. For this reason, new solutions need to be designed to solve. Disclosure of utility model The utility model aims to provide a telescopic combined prism so as to solve the technical problems that when a total station is used for measurement, the vision of the total station and the prism position is blocked, the measurement cannot be completed, meanwhile, the single prism angle is fixed, so that the measured range is limited, the diversified measurement requirements cannot be met, and the applicability of the single prism is reduced. In order to solve the problems, the utility model adopts the following technical means: The utility model provides a telescopic combination prism, includes the inserted bar, and the coaxial structure of top structure of inserted bar has circumference adjustment mechanism, and coaxial rotation installs a plurality of extensible members on the circumference adjustment mechanism, and prism adjusting part is installed to the one end that every extensible member kept away from the inserted bar. Preferably, the circumferential adjusting mechanism comprises a fixed cylinder coaxially arranged at the top end of the inserted link, a plurality of annular grooves extending and arranged along the axial direction are coaxially formed in the surface of the fixed cylinder, a first damping bearing is arranged in the annular grooves, and the telescopic piece is arranged on the outer wall of the first damping bearing.
