[0026] The specific structure and working process of the irregular sample clamping device of the present application will be described below. Figures 1 to 3 The specific structure and working process of the irregular sample clamping device of the present application will be described below.

[0027] One embodiment of the present application provides an irregular sample clamping device, referring to Figure 1 As shown in the figure, it comprises a sample preparation base plate 1, a support sleeve 2 and a clamping piece 3, the sample preparation base plate 1 is used for placing the irregular sample to be measured; the support sleeve 2 is placed on the sample preparation base plate 1, and the irregular sample to be measured is located in the support sleeve 2; the clamping piece 3 is detachably connected to the support sleeve 2, the clamping piece 3 comprises a fixed clamping part and a movable clamping part, and is suitable for moving towards the fixed clamping part through the movable clamping part to clamp the irregular sample to be measured.

[0028] The clamping device for the irregular sample of the embodiment can be used for sample preparation and clamping of the sample during X-ray diffraction instrument testing of the irregular sample. Specifically, the sample preparation base plate 1 is placed on a flat table top. The sample preparation base plate 1 is a flat stainless steel sheet and is placed at the bottom of the device during sample preparation, thereby assisting the device to be flipped after sample preparation is completed. The irregular sample to be tested is placed on the sample preparation base plate 1 with the testing surface facing downward. According to the shape of the irregular sample to be tested, a suitable clamping position is determined (the clamping position is generally selected to be a symmetrical part of the circumferential direction of the irregular sample to be tested). According to the height of the clamping position of the irregular sample to be tested, a support sleeve 2 with a suitable height is selected, and a clamping piece 3 is connected to the support sleeve 2 at a height corresponding to the clamping position of the irregular sample to be tested. The support sleeve 2 is sleeved around the irregular sample to be tested, and the movable clamping part and the fixed clamping part of the clamping piece 3 are used to clamp the irregular sample to be tested. After the above steps are completed, the sample preparation base plate 1 and the support sleeve 2 are buckled and flipped by 180°, so that the testing surface of the irregular sample to be tested is in an upward state. Then, the whole device is placed in the X-ray diffraction instrument, and the sample preparation base plate 1 is removed, and the testing can be started. After being clamped by the clamping device of the embodiment, the testing surface of the irregular sample to be tested can be located at the center of the clamping device, which meets the requirements of the X-ray diffraction instrument for the horizontal position of the sample. The XRD sample clamping of the irregular material can be conveniently and quickly realized, the standard degree of the sample preparation process is improved, and human error is reduced.

[0029] In some embodiments of the clamping device for the irregular sample of the utility model, the support sleeve 2 comprises a plurality of detachable standard height sleeves. The upper end and the lower end of each standard height sleeve are provided with a buckling structure to realize detachable connection of adjacent two standard height sleeves through the buckling structure. The clamping piece 3 is detachably connected between two adjacent standard height sleeves.

[0030] It can be understood that the support sleeve 2 in the embodiment is formed by buckling a plurality of detachable standard height sleeves through the buckling structure, thereby forming a detachable splicing structure. The standard height sleeve can be used for adjusting the position of the sample testing surface to be at the standard testing height required by the XRD equipment, thereby facilitating standardized testing. According to the clamping height of the sample, a standard height sleeve with a suitable number of layers is selected to be buckled and spliced, thereby forming a suitable clamping height of the sample. Then, the clamping piece 3 is connected to the sample for clamping, and another standard height sleeve with a suitable number of layers is selected to be connected to the clamping piece 3, thereby forming the final support height of the sample. By adjusting the position of the clamping piece 3 in different layers of the support sleeve 2, testing of samples with different sizes can be realized.

[0031] It should be understood that, Figure 1The schematic clamping piece 3 is on the sample preparation base plate 1, and no other standard height sleeve is arranged between the clamping piece 3 and the sample preparation base plate 1, and the clamping piece 3 can generally be used for clamping a sample with a relatively small size; in actual cases, when the sample has a relatively large size, different numbers of standard height sleeves are buckled above and below the clamping piece 3, the height of the standard height sleeve below the clamping piece 3 is the distance from the sample clamping part to the test surface, and the height of the standard height sleeve above the clamping piece 3 plus the height of the standard height sleeve below the clamping piece 3 is the height of the test surface of the sample in the X-ray diffractometer.

[0032] Further, in another embodiment of the irregular sample clamping device of the utility model, the clamping piece 3 further comprises a connecting ring 31 for supporting and fixing the fixed clamping part and the movable clamping part, and the upper ring surface and the lower ring surface of the connecting ring 31 are also provided with buckling structures suitable for detachable connection with the buckling structures of the standard height sleeve.

[0033] In some specific examples, the buckling structure comprises a groove on one end surface of the standard height sleeve / connecting ring 31 and a protrusion on the other end surface of the standard height sleeve / connecting ring 31, and the protrusion and the groove are suitable for adaptive plug-in connection. The male and female buckling structures formed by the protrusion and the groove are suitable for detachable connection of the standard height sleeve with the connecting ring 31 and the adjacent two layers of standard height sleeves.

[0034] In some embodiments of the irregular sample clamping device of the utility model, a fixed clamping column is fixed in the connecting ring 31 to form the fixed clamping part; the movable clamping part is hinged to the connecting ring 31, and a movable clamping column is fixed to the position of the movable clamping part in the connecting ring 31, and the movable clamping column is suitable for moving towards the fixed clamping column to clamp the irregular sample to be tested.

[0035] It can be understood that the connecting ring 31 and the support sleeve 2 have the same inner diameter and are connected to form an integral whole, and the fixed clamping part and the movable clamping part in the connecting ring 31 are used for clamping the sample, and the sample is clamped by the fixed clamping column and the movable clamping column. In one specific example of the irregular sample clamping device of the utility model, as shown in Figure 2 The fixed clamping column comprises a first clamping column 32 and a second clamping column 33, and the movable clamping column comprises a third clamping column 34, and the first clamping column 32, the second clamping column 33 and the third clamping column 34 are uniformly distributed in a circumferential direction around the center of the connecting ring 31. The first clamping column 32 and the second clamping column 33 are fixed and immovable, and the third clamping column 34 moves towards the first clamping column 32 and the second clamping column 33 along with the movable clamping part, and the three clamping columns stably clamp the sample at the center position of the support sleeve 2.

[0036] Further, the end of the fixed clamping column and the movable clamping column is sleeved with a silica gel sleeve, the silica gel sleeve can increase the friction of the end of the fixed clamping column and the movable clamping column, facilitate clamping smooth samples, and the silica gel sleeve has a certain elastic buffering function, so that the sample is not easily damaged by the clamping column. It should be understood that the fixed clamping column and the movable clamping column should be outside the test scanning range when finally performing the XRD equipment test, and the test effect is not affected.

[0037] In some specific examples of the clamping device for irregular samples of the utility model, referring to the figure, it can be understood that the fixed handle 35 and the movable clamping handle 36 are arranged, and the spring sheet 37 is arranged between the part of the movable clamping handle 36 outside the connecting ring 31 and the fixed handle 35, and the movable clamping handle 36 is fixed with the movable clamping column in the part inside the connecting ring 31.

[0038] Continuing to refer to Figure 2 It can be understood that the fixed handle 35 and the movable clamping handle 36 are arranged, and the spring sheet 37 is arranged, the clamping piece 3 remains the clamping state in the non-use state, the fixed handle 35 and the movable clamping handle 36 can be held by one hand when used, so that the spring sheet 37 is extruded and deformed, the clamping piece 3 is in the open state, the irregular sample is between the fixed clamping column and the movable clamping column, the fixed handle 35 and the movable clamping handle 36 are released, and the fixed clamping column and the movable clamping column can complete the clamping of the irregular sample under the reset of the spring sheet 37.

[0039] Specifically, in some specific examples of the clamping device for irregular samples of the utility model, referring to Figure 3 It can be understood that the fixed handle 35 and the movable clamping handle 36 are arranged, and the spring sheet 37 is arranged, the clamping piece 3 remains the clamping state in the non-use state, the fixed handle 35 and the movable clamping handle 36 can be held by one hand when used, so that the spring sheet 37 is extruded and deformed, the clamping piece 3 is in the open state, the irregular sample is between the fixed clamping column and the movable clamping column, the fixed handle 35 and the movable clamping handle 36 are released, and the fixed clamping column and the movable clamping column can complete the clamping of the irregular sample under the reset of the spring sheet 37.

[0040] In combination with Figure 2 And Figure 3As shown, it can be understood that the movable clamping handle 36 in the example is in a "V" shape, and is divided into a clamping rod 361 inside the connecting ring 31 and an adjusting rod 362 outside the connecting ring 31 by a position where the connecting ring 31 is hinged. In a non-use state, the clamping rod 361 and the fixed handle 35 are in a line, at which time the spring sheet 37 is in a natural state, and the clamping piece 3 is in a clamped state. When the clamping piece 3 needs to be used to clamp a sample, the fixed handle 35 and the adjusting rod 362 are held, the spring sheet 37 is extruded, the clamping rod 361 and the adjusting rod 362 rotate around the hinged shaft on the connecting ring 31, the movable clamping column on the clamping rod 361 starts to move away from the fixed clamping column, so that the clamping piece 3 is in an open state, and the irregular sample is placed between the fixed clamping column and the movable clamping column, the fixed handle 35 and the clamping rod 361 are released, and the fixed clamping column and the movable clamping column complete clamping of the irregular sample under the reset of the spring sheet 37.
