Summary of the invention
The purpose of this utility model is to overcome the deficiencies in the prior art and provides a kind of easy to use, constitutionally stable adjustable gem refractometer.
Realizing the technical scheme that the utility model object adopts is, a kind of adjustable gem refractometer, at least comprise refractometer main body, the below of refractometer main body is provided with firm banking, firm banking is provided with regulating device, and refractometer main body is installed on above firm banking by regulating device, described regulating device comprises control gear, transmitting gear and more than 1 group screw thread elevating mechanism, the regulation and control groove of one end open is offered in firm banking, the opening of regulation and control groove is positioned at the side of firm banking, the first fixed leg and the second fixed leg is vertically provided with in regulation and control groove, transmitting gear and control gear to be installed in the horizontal direction respectively on the first fixed leg and the second fixed leg and to engage each other, the teeth portion of control gear protrudes from the opening of regulation and control groove, described screw thread elevating mechanism is formed by regulating Rotational Cylindrical and lifting disk, the bottom regulating Rotational Cylindrical is gear shaft, top is screw rod, the bottom of refractometer main body offers diameter and is greater than adjustment rotation column diameter and the lifting groove of lower ending opening, Rotational Cylindrical is regulated to be installed in firm banking by bearing A, the bottom of Rotational Cylindrical is regulated to engage with transmitting gear, top is arranged in lifting groove, lifting disk to be fixed in the opening of lifting groove and to be placed on and regulates the top of Rotational Cylindrical.
Transmitting gear is installed on the first fixed leg by bearing B.
Described lifting disk is the square plate that threaded hole is offered in centre.
Control gear and the second fixed leg clearance fit.
Described regulating device comprises control gear, transmitting gear and 2 groups of screw thread elevating mechanisms, and 2 groups of screw thread elevating mechanisms are symmetrically distributed in transmitting gear both sides.
As shown from the above technical solution, the adjustable gem refractometer that the utility model provides, refractometer main body is installed on above firm banking by regulating device, regulating device comprises control gear, transmitting gear and more than 1 group screw thread elevating mechanism, wherein control gear and transmitting gear put on screw thread elevating mechanism for generation of moment of torsion, screw thread elevating mechanism is used for torque axis to turn to rectilinear motion, because screw thread elevating mechanism is vertically installed, therefore the height adjustment of refractometer main body is realized by transmitting gear transmission, the teeth portion of control gear protrudes from the opening of regulation and control groove, the teeth portion protruding from regulation and control channel opening by stirring control gear can realize the rotation of control gear, this structure can realize the lift adjustment repeatedly of refractometer main body, easy to use, screw thread elevating mechanism is formed by regulating Rotational Cylindrical and lifting disk, the bottom of Rotational Cylindrical is regulated to be gear shaft, to engage with transmitting gear, the top regulating Rotational Cylindrical is screw rod, is arranged in lifting groove and is threaded with lifting disk, lifting disk is fixed in refractometer main body, when regulating Rotational Cylindrical to rotate, lifting disk rises or declines under the effect of screw thread, drives the lifting of refractometer main body.
For ensureing lifting disk and refractometer main body stable connection and not relatively rotating, lifting disk is designed to the square plate that threaded hole is offered in centre, and the corner of square plate limits lifting disk degree of freedom in the horizontal direction; The quantity of screw thread elevating mechanism preferably 2 groups, 2 groups of screw thread elevating mechanisms are symmetrically distributed in the both sides of transmitting gear, guarantee that refractometer main body steadily rises.
Compared with prior art, the observer that the adjustable gem refractometer that the utility model provides is convenient to different height observes, and person's demand can carry out height adjustment according to the observation, use comfortable, simultaneously in adjustment process, refractometer main body can steadily rise, Stability Analysis of Structures.
