Description

Technical Field

[0001] This utility model relates to the field of spectrophotometer technology, and in particular to a fixed angle measuring device for a spectrophotometer. Background Technology

[0002] A spectrophotometer is an instrument that determines the concentration of a substance or performs component analysis by measuring the degree to which the substance absorbs light of different wavelengths. A spectrophotometer mainly consists of a light source, a monochromator, a sample cell, a detector, and a data processing system.

[0003] A search revealed Chinese Patent Publication No. CN218782190U, which discloses a fixed angle measuring device for a spectrophotometer. The device includes a base with a longitudinally arranged support seat dividing the base into a first measurement area and a second measurement area. When the product to be measured is placed in either the first or second measurement area and rests against the support seat to form a product placement cavity, a measuring optical path is arranged parallel to the base and corresponding to the product placement cavity. The light transmission direction of the measuring optical path forms a light incident angle of 0°, 30°, 35°, or 45° with the normal to the product to be measured. In this invention, the measuring optical path continuously enters the product placement cavity at an angle parallel to the base, ensuring a fixed light transmission direction and a unique angle. By placing the product to be measured in the corresponding angle-fixed slot within the first or second measurement area, the light incident angle between the normal to the product and the light transmission direction of the measuring optical path is adjusted, thereby accurately measuring the spectroscopic angle of the product.

[0004] The above-mentioned device has the following defects: the upper fixed frame can only detect specific values. When it is necessary to detect the use of the spectrophotometer at multiple deflection angles, it cannot meet the requirements of large-range deflection angle detection, which makes the device have a large limitation on the range of deflection angle detection. Therefore, a fixed angle measuring device for spectrophotometer is proposed to solve the above problems. Utility Model Content

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Reference Figure 1 - Figure 2 This utility model provides an embodiment of a fixed angle measuring device for a spectrophotometer, comprising a base plate 1, which supports the device. A motor 2 is fixedly connected to the axis of the front surface of the base plate 1, and a reciprocating lead screw 3 is fixedly connected to the output shaft of the motor 2. The operator drives the reciprocating lead screw 3 to rotate by starting the motor 2. The rotation of the reciprocating lead screw 3, in conjunction with the groove on the upper surface of the base plate 1, achieves the adjustment of the device in the forward and backward direction, improving the convenience of device adjustment and use. An adjustment component 4 is provided on the upper surface of the base plate 1, and an angle deflection component 5 is provided on the upper side of the adjustment component 4.

[0025] Reference Figure 2 - Figure 4When multiple changes in the fixed angle of the equipment need to be detected, the deflection assembly 5 is activated. The deflection assembly 5 includes a support frame 55, which is hinged to the inner wall of the deflection seat 57 via a rotating column 54. After the detection equipment is installed through the groove of the support frame 55, the operator manually contacts the fixing nut 52. The rotating column 54 is fixedly connected to the lower side of the front surface of the support frame 55. The front surface of the protractor 51 has a positioning groove 53. By adjusting the support frame 55, the support frame 55 can be rotated and adjusted in the deflection seat 57 under the action of the rotating column 54. The front end of the rotating column 54 is connected to the protractor 51. The angle is obtained during the deflection rotation through the protractor 51, improving the equipment's deflection adjustment capabilities. To ensure accuracy during adjustment, the rear end of the rotating column 54 is hinged to an angle bracket 57. The lower surface of the angle bracket 57 is fixedly connected to the upper surface of the sliding frame 45. The front surface of the support frame 55, near the upper side of the rotating column 54, is fixedly connected to a positioning column 56. After the angle adjustment of the support frame 55 is completed, the movement of the positioning column 56 in the positioning groove 53 ends. The positioning column 56 is limited and fixed by the fixing nut 52 in conjunction with the positioning groove 53. The outer arc surface of the outer wall of the positioning column 56 is detachably connected to the fixing nut 52, so that the support frame 55 is in a fixed state after the angle adjustment is completed. This improves the accuracy and convenience of the equipment angle calibration, realizes the fixed detection function of the equipment under any angle, and expands the applicable range of the equipment angle adjustment.

[0026] Reference Figure 2 - Figure 4 When the angle component 5 needs to be moved and adjusted, the adjustment component 4 is activated. The adjustment component 4 includes a mounting plate 41, which is slidably connected to the groove on the upper surface of the base plate 1 via a movable seat 43. The movable seat 43 is fixedly connected to the lower surface of the mounting plate 41. The rotation of the reciprocating screw 3 is controlled by the rotation of the motor 2. The inner wall groove of the movable seat 43 is threadedly connected to the outer wall thread of the reciprocating screw 3. The rotation of the reciprocating screw 3 drives the movable seat 43 to rotate, realizing the adjustment of the equipment in the front and back direction. Two sets of sliding grooves 42 are opened on the upper surface of the mounting plate 41. An electric telescopic rod 44 is fixedly connected to the right end of the upper surface of the mounting plate 41. The operator controls the electric telescopic rod 44. A sliding frame 45 is fixedly connected to the left end of the electric telescopic rod 44. The lower surface of the sliding frame 45 is slidably connected to the inner wall of the sliding groove 42, so that the electric telescopic rod 44 moves and the sliding frame 45 is adjusted horizontally in the sliding groove 42, which improves the convenience of the operator in adjusting the equipment displacement and enhances the convenience of the equipment adjustment process.

[0027] Working principle: When multiple changes in the fixed angle of the equipment need to be detected, the deflection component 5 is activated. After the detection equipment is installed through the groove of the support frame 55, the operator manually contacts the fixing nut 52. By adjusting the support frame 55, the support frame 55 rotates in the deflection seat 57 under the action of the rotating column 54. The angle is obtained during the deflection rotation through the protractor 51, which improves the accuracy of the equipment when adjusting the deflection angle. When the deflection angle of the support frame 55 is adjusted, the movement of the positioning column 56 in the positioning groove 53 ends. The fixing nut 52, in conjunction with the positioning groove 53, limits and fixes the positioning column 56, so that the support frame 55 is in the deflection position. After the angle adjustment is completed, it is in a fixed state, which improves the accuracy and convenience of the equipment's angle calibration, realizes the fixed detection function of the equipment under any angle, and expands the applicable range of the equipment's angle adjustment. When it is necessary to move and adjust the angle component 5, the adjustment component 4 is activated, and the operator controls the electric telescopic rod 44, so that the electric telescopic rod 44 moves the sliding frame 45 in the slide groove 42 to adjust left and right in the horizontal direction. The rotation of the motor 2 controls the rotation of the reciprocating screw 3, and the rotation of the reciprocating screw 3 drives the moving seat 43 to rotate, realizing the adjustment of the equipment in the front and back direction, improving the convenience of the operator to adjust the equipment displacement, and enhancing the convenience of the equipment adjustment process.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
