TECHNICAL FIELD

[0001] The present application relates to the field of optical detection equipment, in particular to a sample stage clamp of an X-ray diffractometer. BACKGROUND

[0002] X-ray diffraction utilizes the diffraction phenomenon of X-rays in crystals to obtain the characteristics of the X-ray signal after diffraction, and obtains the diffraction pattern after processing. By performing X-ray diffraction on a material, analyzing the diffraction pattern, and obtaining information such as the composition of the material, the structure or morphology of the atoms or molecules inside the material, etc.

[0003] The X-ray diffractometer is such that the X-ray beam is irradiated on the sample through the soller slit, the divergence slit, the sample stage is located at the center of the goniometer, based on the reflection geometry θs-θd, the X-ray beam occurs diffraction phenomenon in a specific direction when the Bragg's law is satisfied, and finally the collected diffraction pattern is displayed on the analysis software through the data processing system after passing through the anti-scattering slit, the soller slit, the receiving slit and the X-ray detector.

[0004] The traditional diffractometer includes an internal hollow body, a sample stage, an X-ray generator and a detector arranged in the body, and a clamp for clamping a slide, and the detection sample is placed on the slide.

[0005] The existing clamp mostly adopts bolt clamping, but the tightening of the bolt is usually realized manually by workers, and the thickness of the slide is thin and fragile, so the slide is easily broken when the worker tightens it too hard, and the detection sample will also scatter in the body, which has obvious defects. CONTENT OF THE INVENTION

[0006] In order to improve the problem that the slide may be broken due to excessive force when clamping the slide, the present application provides a sample stage clamp of an X-ray diffractometer.

[0008] The sample stage clamp of the X-ray diffractometer includes a boss arranged on the inner side wall of the body, and a resilient sheet arranged below the boss in the body, one end of the resilient sheet is used to clamp the slide against the lower surface of the boss, and the other end is arranged on the inner side wall of the body.

[0009] By adopting the above technical scheme, when installing, the worker manually bends the resilient sheet downward, and then inserts the slide between the resilient sheet and the boss. After releasing the resilient sheet, the resilient sheet restores the deformation, so as to clamp the slide against the boss. The boss and the resilient sheet cooperate to clamp the slide, the clamping process is convenient, and the clamping force of the resilient sheet on the slide remains constant, which reduces the possibility of damage of the slide due to excessive force.

[0010] Optionally, the elastic sheet is attached with an elastic layer at the position for abutting against the slide glass.

[0011] By adopting the technical scheme, the elastic layer changes the rigid contact between the elastic sheet and the slide glass into flexible contact, thereby protecting the slide glass.

[0012] Optionally, one end of the elastic sheet is attached with a pull rope relative to the slide glass, and the bottom end of the pull rope is attached with a pull head.

[0013] By adopting the technical scheme, the worker can conveniently deform the elastic sheet through the pull rope.

[0014] Optionally, the pull rope is an elastic rope.

[0015] By adopting the technical scheme, since the pull rope itself has elasticity, the deformation degree of the elastic sheet when the worker pulls the pull rope is reduced, thereby reducing the impact of the elastic sheet on the slide glass.

[0016] Optionally, a vertical slide rail strip is arranged on the inner wall of the machine body, a lifting block is slidably arranged on the slide rail strip, the cross sections of the slide rail strip and the lifting block in sliding fit are dovetail-shaped, the elastic sheet is bolted to the lifting block, and a fastening bolt for abutting against the slide rail strip is threadedly connected to the lifting block.

[0017] By adopting the technical scheme, when the thickness of the slide glass to be abutted against changes, the worker adjusts the height of the lifting block and locks the height of the lifting block through the fastening bolt, and then re-adjusts the abutting force of the elastic sheet on the slide glass to a proper size.

[0018] Optionally, polytetrafluoroethylene is coated on the lifting block and the slide rail strip.

[0019] By adopting the technical scheme, the friction coefficient of the polytetrafluoroethylene is small, thereby improving the smoothness of the lifting block in the lifting movement on the slide rail strip.

[0020] Optionally, a fixing block is arranged on the inner wall of the machine body relative to the position below the lifting block, a vertical jack is threadedly connected to the fixing block, the top end of the jack is supported on the bottom of the lifting block, a hollow micro-adjustment knob is rotatably sleeved on the bottom end of the jack, a first ratchet wheel is arranged on the bottom end of the jack, a second ratchet wheel is connected to the inner end face of the micro-adjustment knob away from the lifting block through a compression spring, and the first ratchet wheel is engaged with the second ratchet wheel.

[0021] By adopting the technical scheme, when the pressing height of the elastic sheet is adjusted, the worker first rotates the jacking rod, so that the elastic sheet quickly approaches the boss. After approaching the boss, the fine adjustment knob is rotated, the second ratchet wheel drives the first ratchet wheel to rotate synchronously, the jacking rod rotates and gradually rises, until the elastic sheet presses the glass sheet on the boss, the first ratchet wheel remains stationary, and the second ratchet wheel continues to rotate. At this time, the first ratchet wheel collides with the second ratchet wheel, and the worker will hear the sound of "click, click". At this time, the height of the elastic sheet is adjusted to the right position, and the pressing force is appropriate. The worker manually tightens the fastening bolt.

[0022] Optionally, the outer side wall of the fine adjustment knob is provided with anti-skid lines.

[0023] By adopting the technical scheme, the anti-skid lines can reduce the possibility of slipping when the worker manually rotates the fine adjustment knob.

[0024] In summary, the present application has at least one of the following beneficial technical effects:

[0025] 1. When installing, the worker manually bends the elastic sheet downward, and then inserts the glass sheet between the elastic sheet and the boss. After releasing the elastic sheet, the elastic sheet restores the deformation, so as to press the glass sheet on the boss. In this way, the boss cooperates with the elastic sheet to realize clamping of the glass sheet. The clamping process is convenient to operate, and the pressing force of the elastic sheet on the glass sheet remains constant, reducing the possibility of damage to the glass sheet due to excessive force.

[0026] 2. When the thickness of the pressed glass sheet changes, the worker adjusts the height of the lifting block and locks the height of the lifting block through the fastening bolt, so as to re-adjust the pressing force of the elastic sheet on the glass sheet to an appropriate size.

[0027] 3. When the pressing height of the elastic sheet is adjusted, the worker first rotates the jacking rod, so that the elastic sheet quickly approaches the boss. After approaching the boss, the fine adjustment knob is rotated, the second ratchet wheel drives the first ratchet wheel to rotate synchronously, the jacking rod rotates and gradually rises, until the elastic sheet presses the glass sheet on the boss, the first ratchet wheel remains stationary, and the second ratchet wheel continues to rotate. At this time, the first ratchet wheel collides with the second ratchet wheel, and the worker will hear the sound of "click, click". At this time, the height of the elastic sheet is adjusted to the right position, and the pressing force is appropriate. The worker manually tightens the fastening bolt. BRIEF DESCRIPTION OF DRAWINGS
