On the base of the sample table, a device consisting of a joystick, an arm rod, a positioning pin, a sample fixing clip and an inner hexagonal bolt is arranged. Mechanical clamping device. Turn the joystick to drive the arm to rotate around the positioning pin, and at the same time drive the sample on the positioning pin to move, so that the sample can be bent laterally to achieve the purpose of dynamic change.

Description

The device used for XRD sample stage can make the sample bend laterally

Technical field:

The utility model relates to a device for XRD that can dynamically change a sample, in particular to the field of preparation and research and development of a sample platform that can make the sample bend laterally. the

Background technique:

XRD is a common measurement device for scientific research and teaching. The sample is fixed on the existing ordinary sample stage and placed in the monochromator. The sample can be placed on the sample stage, and the sample cannot be bent laterally, and the deformation operation of the sample cannot be realized, and the sample is often required in the experiment. The change of lateral bending can achieve the best effect, and if the lateral bending operation is directly performed on the sample during the experiment, it often affects the progress of the experiment. This is the weak point that existing technology exists. the

Invention content:

The purpose of this utility model is to provide a device with lateral bending function and simple structure to solve the shortcomings of the prior art. This device can not only realize the purpose of dynamic change of samples, but also has low cost and strong practicability. the

The technical solution adopted by the utility model to solve the technical problem is: a device for laterally bending the sample on the XRD sample stage, including a sample stage base, a joystick, an arm lever, a positioning pin, a sample fixing clip and an inner hexagon bolt. In this device, the joystick is threadedly connected to the wall of the sample stage, and is connected flexibly with the arm; the fixed end of the arm is connected to the wall of the sample stage with a positioning pin; one of the positioning pins is fixed on the upper sample fixing clip, and the other two One is fixed on the positioning pins on both sides of the boom. When the joystick is turned, it drives the arm to rotate around the positioning pin, and at the same time drives the sample on the positioning pin on the arm to move, so as to achieve the purpose of lateral bending of the sample. the

The beneficial effect of the utility model is that the lateral bending of the sample can be carried out and dynamic changes can be realized. In addition, the sample stage only includes a mechanical clamping part, and has a simple structure, low cost and strong practicability. the
