Abstract
Description
Technical Field
[0001] The utility model relates to the field of X-ray diffractometers, in particular to a sample table of an X-ray diffractometer. Background Art
[0002] X-ray diffractometer is an instrument used to study the crystal structure, morphology and properties of materials. It uses the interaction between X-rays and crystals to determine the structural parameters and unit cell size of the crystal by measuring the diffraction angle and intensity of X-rays in the crystal. X-ray diffractometer mainly consists of a movable X-ray source, a sample stage for placing the sample to be tested, a detector for receiving X-rays diffracted by the sample, a control circuit for controlling the switch of the X-ray source, and data processing software.
[0003] Among them, for powdered samples, most of them are placed on the surface of a glass slide, and then the glass slide is placed on a sample stage for detection. The sample stage is mostly suspended above the table of the X-ray diffractometer. In order to ensure the stability of the sample, the glass slide needs to be positioned on the sample stage. The existing positioning structure installed on the sample stage can only position a glass slide of one specification. In addition, since the glass slide is thin, in the process of installing and removing the glass slide, not only manual operation of the positioning structure is required, but also the stability of the glass slide needs to be maintained. If the staff does not operate properly, the glass slide is prone to offset and fall, affecting the safety of the sample. Utility Model Content

DETAILED DESCRIPTION
[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0022] Example: Reference Figure 1-3 An X-ray diffractometer sample stage shown in the figure includes a positioning pillar 1, a pair of guide arms 2 are provided on the positioning pillar 1, and a movable connecting arm 3 is provided on the pair of guide arms 2. The ends of the connecting arms 3 exposed in front of the positioning pillar 1 are connected to the positioning arms 4 through a rotating shaft, and the ends of the positioning arms 4 away from the rotating shaft are provided with channels for accommodating the placement of glass slides. The positioning arms 4 are provided with pressure pieces 5 that can contact the glass slides, and the pressure pieces 5 are located on the inner side of the channels.
[0023] The connecting arms 3 are provided with brackets 31, and the brackets 31 are provided with cavities for accommodating glass slides. The glass slides can be placed inside the cavities, and then the positioning arms 4 are controlled to move, and the edges of the glass slides are located inside the channels until the pressure piece 5 is clamped on the glass slides. In this process, the stability of the glass slides is maintained, and the glass slides are prevented from being offset or falling during the operation of the positioning arms 4 and the pressure piece 5, thus protecting the glass slides.
[0024] At the same time, since the angles of the positioning arm 4 and the engagement arm 3 are adjustable, the positioning arm 4 and the pressure member 5 can be adapted to the clamping and positioning operations of glass slides of different specifications. The design of the bracket 31 can also accommodate glass slides of different specifications. Since the position of the engagement arm 3 is adjustable, glass slides of different specifications cannot collide with the surface of the positioning pillar 1.
[0025] like Figure 4 , Figure 5As shown, the positioning arms 4 are provided with channels, and the pressure member 5 is composed of a horizontal plate parallel to the positioning arms 4 and oblique plates at both ends of the horizontal plate body. In a natural state, the horizontal plate is located below the channel, and the oblique plates are symmetrically distributed on the inner side of the channel. In the process of installing and removing the glass slide, the movement of the horizontal plate can be controlled by controlling the movement of the oblique plates, without touching the horizontal plate, effectively avoiding the staff from accidentally touching the glass slide and the powder sample on its surface, thereby ensuring the safety of the glass slide and the sample.
[0026] like Figure 4 , Figure 5 As shown, the positioning arms 4 are each provided with a connecting beam 41, which is located directly above the channel, and the connecting beam 41 is provided with a plurality of first connecting column heads 6 distributed equidistantly, and the cross plate is provided with a plurality of second connecting column heads 7 corresponding to the first connecting column heads 6, and the first connecting column heads 6 and the second connecting column heads 7 are connected by a pressure spring 8. During the installation of the glass slide, as the cross plate rises, the second connecting column heads 7 move toward the first connecting column heads 6 until the pressure spring 8 contracts, leaving space for inserting the glass slide, thereby driving the pressure piece 5 to smoothly clamp the glass slide.
[0027] like Figure 3 As shown, the guide arm 2 is provided with a rotatable limit pin 21, the end of the limit pin 21 is located on the inner side of the guide arm 2, and when the connecting arm 3 moves to a specified extent along the guide arm 2, the end of the limit pin 21 located on the inner side of the guide arm 2 abuts against the connecting arm 3. The stability of the connecting arm 3 is maintained, and the sliding deviation phenomenon of the connecting arm 3 is avoided again, which further ensures the stability of the slide.
[0028] like Figure 3 As shown, in order to identify the movement data of the connecting arm 3, a scale mark 22 is provided on the surface of the guide arm 2, and an indicator bar 32 corresponding to the scale mark 22 is provided on the surface of the connecting arm 3 received in the guide arm 2. The movement data of the connecting arm 3 can be identified by the relative position between the indicator bar 32 and the scale mark 22.
[0029] like Figure 3 As shown, in order to save the installation space of the guide arm 2 and make rational use of the space, a receiving space 11 is opened on the positioning pillar 1 , and the guide arm 2 is located inside the receiving space 11 .
[0030] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
