Description

Technical Field

[0001] The utility model relates to the technical field of spectral instruments, in particular to an adjustable object carrier for spectral instruments. Background Art

[0002] Spectroscopic instruments include infrared spectrometers, ultraviolet spectrometers, spectrophotometers, etc. In the use of the above-mentioned spectroscopic instruments, it is necessary to illuminate the sample, and by measuring the light reflected from the sample surface, the substance is quantitatively or qualitatively analyzed to find out what elements are contained in the sample. This requires a sample carrier to meet the needs of the spectroscopic instrument for sample analysis.

[0003] However, the current sample carrier cannot effectively adjust the incident light angle of the sample. If the incident light angle needs to be changed, the carrier must be reinstalled, which is not only inefficient but also the adjustment accuracy cannot meet the requirements. Utility Model Content

DETAILED DESCRIPTION

[0020] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments.

[0021] like Figure 1 As shown, an adjustable specimen carrier for a spectroscopic instrument includes a specimen carrier body 1 and a base 2, wherein the specimen carrier body 1 includes a bearing portion 11 and a connecting portion 12, wherein the bearing portion 11 is fixedly connected to the connecting portion 12, and the connecting portion 12 is connected to the base 2 via a spacing adjustment component 3; an angle adjustment slot 4 is formed on the base 2, wherein an angle adjustment member 5 is installed in the angle adjustment slot 4, and the angle adjustment member 5 abuts against a side of the connecting portion 12 near the base 2. The bearing portion 11 and the connecting portion 12 adopt an integrally formed structure, and the forming method may be die casting or the like. In other embodiments, the bearing portion and the connecting portion may also adopt a split structure, such as by bolt connection, connecting member connection, or the like.

[0022] In the present invention, the specific shape of the base is not limited, and the cross-section of the base can be rectangular, square, circular, or elliptical. Similarly, the shape of the connecting portion is not limited, and the cross-section of the connecting portion can be rectangular, square, circular, or elliptical. The connecting portion and the base only need to meet the requirements of the angle adjustment member and the spacing adjustment assembly, so that the carrier body can be adjusted on the base to the desired angle and direction.

[0023] In order to ensure the accuracy and direction of angle adjustment, the angle adjustment groove 4 includes a first groove 41, a second groove 42 and a third groove 43, wherein the first groove 41 is located at the center of the base 2, and the second groove 42 and the third groove 43 are symmetrically distributed on the left and right sides or the front and back sides of the first groove 41.

[0024] Specifically, the angle adjustment member 5 adopts a ball, and the angle adjustment groove 4 adopts a groove with a circular cross section. Among them, if the ball is placed in the first groove 41, when the ball rotates, the four directions of the carrier can be adjusted in front and back, left and right. This is because the first groove 41 is located at the center of the base. When the ball rotates to adjust the carrier, the connection part will not be unbalanced due to the center of gravity shift, so that the angle and direction of the carrier cannot be adjusted. If two balls are placed in the second groove 42 and the third groove 43 respectively, the carrier can be adjusted in the front and back or left and right directions. In this way, although it can only be adjusted in the front and back or left and right directions, and the adjustment in the four directions of front and back, left and right cannot be achieved at once, this method is easier to operate when adjusting, and there is no need to worry about the center of gravity of the connection part being shifted due to improper operation, causing the carrier to tip over.

[0025] In order to adjust the angle of the storage rack in all directions, the spacing adjustment assembly 3 may include a first adjustment member 31, a second adjustment member 32, a third adjustment member 33 and a fourth adjustment member 34, and the distances from the center point of the connecting portion 12 to the first adjustment member 31, the second adjustment member 32, the third adjustment member 33 and the fourth adjustment member 34 are the same.

[0026] Specifically, the first adjusting member 31 , the second adjusting member 32 , the third adjusting member 33 or the fourth adjusting member 34 adopts fastening screws, and threaded holes are provided at corresponding positions of the base 2 .

[0027] In other embodiments, the first adjusting member 31, the second adjusting member 32, the third adjusting member 33 and the fourth adjusting member 34 may also be workpieces such as telescopic rods that can change the distance between the base 2 and the connecting portion 12. Compared with other workpieces, the combination of fastening screws and threaded holes can more accurately adjust the distance between various parts of the base and the connecting portion.

[0028] Since the test sample is placed in the circular hole in the middle of the bearing portion 11 during use, the angle and direction changes of the carrier body 1 are consistent with the angle and direction changes of the test sample. The following is an example of the installation of the ball into the first groove 41. If the carrier body 1 needs to be tilted forward, the first adjustment member 31 and the second adjustment member 32 are loosened according to the required tilt angle, and the third adjustment member 33 and the fourth adjustment member 34 are tightened; if the carrier body 1 needs to be tilted backward, the third adjustment member 33 and the fourth adjustment member 34 are loosened according to the required tilt angle, and the first adjustment member 31 and the second adjustment member 32 are tightened; if the carrier body 1 needs to be tilted to the left, the second adjustment member 32 and the third adjustment member 33 are loosened according to the required tilt angle, and the first adjustment member 31 and the fourth adjustment member 34 are tightened; if the carrier body 1 needs to be tilted to the right, the first adjustment member 31 and the fourth adjustment member 34 are tightened, and the second adjustment member 32 and the third adjustment member 33 are tightened. In the case where the ball bearings are installed in the second groove 42 and the third groove 43 , the adjustment method is similar to the aforementioned adjustment method and will not be described in detail.
