Description

Technical Field

[0001] The utility model relates to the field of sample racks, in particular to a sample rack device which can be quickly positioned and installed. Background Art

[0002] Due to the high brightness, high polarization, and high collimation of synchrotron radiation, continuously adjustable monochromatic light can be obtained, and the X-ray beam can be introduced into the atmosphere for analysis. Synchrotron radiation light source excitation X-ray fluorescence analysis has taken X-ray fluorescence analysis to a new level. Under current conditions, when conducting synchrotron radiation X-ray related experiments, experimental samples need to be frequently replaced. The existing sample holder is very clumsy. Each time a sample is changed, the nut must be turned to remove the entire sample holder from the sample stage. This is not only very inconvenient, but also very easy to damage the screw holes on the sample stage, affecting the accuracy of the sample stage. Different samples also require different sample holders for support, and the sample holders also need to be changed frequently. In other cases where it is not necessary to disassemble the sample holder to change samples, the laboratory sample replacement speed is slow, and the replacement requires shutdown, which affects the progress of the experiment. During the experiment, samples can only be observed under a visible light microscope on the laboratory table, and the magnification is very low. When the sample size is at the micron level, the sample morphology cannot be clearly observed, and offline observation is required under a high-power fluorescence microscope. In order to make the observation image under the high-power microscope consistent with the scanning image of the X-ray fluorescence experiment, a high-precision sample holder is required to ensure that the sample can be aligned with the previous sample position under the microscope, which facilitates the microscope to align the light, focus, and quickly capture images. Utility Model Content

[0003] As mentioned in the background, since the current sample rack cannot achieve the requirements of rapid replacement and accurate positioning, a sample rack with high stability, convenient replacement, and rapid positioning is needed.

[0004] A sample rack device capable of rapid positioning and installation includes a sample rack, a support plate, a base plate, a magnetic material, and steel balls; the sample rack is installed on the support plate, the magnetic material is installed on the support plate and the base plate, the steel balls are installed on the base plate, the support plate and the base plate are positioned by the steel balls, and the magnetic material is connected by magnetic attraction.

[0005] In one embodiment of the present application, the sample holder is provided with a through hole for the light beam to pass through, a sample slot for inserting the sample, and threaded holes for fixed installation are provided on the bottom surface of the sample holder. The number of threaded holes is ≥2, and the sample holder can be replaced with different sample holders according to the properties of different samples.

[0006] In one embodiment of the present application, a through hole is punched at the center of the top surface of the support plate, and threaded holes are provided on both sides of the through hole symmetrically with the center of the through hole. The position and number of the threaded holes are consistent with the position and number of the threaded holes on the bottom surface of the sample holder. Holes for installing and fixing magnetic materials are punched on the bottom surface of the support plate. The size of the holes depends on the magnetic material. There are more than or equal to three holes for installing magnetic materials, which are arranged in a circle or a rectangle with the center hole as the center. A V-shaped groove is left on the bottom surface of the support plate for fixing the steel balls.

[0007] In one embodiment of the present application, the top surface of the base plate has holes for fixing magnetic positions, and the number and position of the holes correspond to the holes for magnetic material on the bottom surface of the support plate. The top surface of the base plate has grooves for fixing steel balls, and the holes correspond to the positions of the V-grooves on the bottom surface of the support plate. Through holes are drilled in the four corners of the base plate.

[0015] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0016] In the description of the present invention, it should be noted that, unless otherwise specified or limited, the terms "installed", "connected", and "connected" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection or an indirect connection through an intermediate medium. For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to the specific circumstances. In this embodiment, Figure 2 As an example, the top surface of the support plate and the top surface of the base plate are shown. Figure 3 Shown are the bottom surfaces of the support plate and the bottom surface of the base plate.

[0017] like Figure 1 The illustrated sample holder device allows for rapid positioning and installation. Sample holder 1 can be replaced with a different sample holder 1 depending on the sample. In this embodiment, sample holder 1 is provided with a light hole 102, allowing the light beam along the optical path to pass through the sample and then through light hole 102 without obstructing the light beam's propagation. Sample holder 1 also includes a sample slot 103, which allows the sample to be quickly inserted into and fixedly installed when replacing or placing the sample. Sample slot 103 also stabilizes the sample's position. Sample holder 1 is mounted on a support plate 2.

[0018] like Figure 2 、 Figure 3 The support plate 2 and base plate 4 shown have two threaded holes and a through hole on the top surface of the support plate 2. The positions of the through holes are consistent with the positions of the through holes on the base plate 4. The bottom surface of the support plate 2 also has four holes for installing magnetic material 5. The hole size is determined by the magnetic material 5. The holes for installing the magnetic material 5 are arranged in a circular or rectangular arrangement around the center hole. The bottom surface of the support plate 2 has a V-shaped groove 301 for the steel ball 3 to be fixed. The top surface of the base plate 4 has holes for fixing magnetic positions. The number and position of the holes correspond to the number and position of the holes for the magnetic material 5 on the bottom surface of the support plate 2. The top surface of the base plate 4 has a groove for fixing the steel ball 3. The hole position corresponds to the position of the V-shaped groove 301 on the bottom surface of the support plate 2. The four corners of the base plate 4 have through holes for connecting to other support platforms, such as optical platforms, lifting platforms, and translation platforms. The center of the base plate 4 has a through hole that is consistent in size and position with the center hole of the support plate 2.

[0019] The magnetic material 5 is installed in the magnetic material installation holes 502 reserved on the support plate 2 and the base plate 4 respectively, and the steel balls 3 are installed in the holes reserved on the base plate 4. When in use, the support plate 2 is placed on the base plate 4, and the V-shaped groove 301 on the bottom surface of the support plate 2 and the steel balls 3 installed on the base plate 4 are positioned together, and then the magnetic material 5 is adsorbed and secured, and then it can be used. When replacing, the sample rack 1 can be directly unplugged, and the support plate 2 will also be removed. Then, other sample racks with samples already installed can be installed to complete the replacement work. This can greatly speed up the progress of the experiment. The support plate 2 and the base plate 4 can be changed to a round style according to actual needs. The steel balls 3 can be replaced with balls made of other materials, which are convenient for fixing in the V-shaped groove 301.
