Description

Technical Field

[0001] The present invention relates to the technical field of spectrophotometers, and particularly to a horizontal spectrophotometer. Background Art

[0002] A spectrophotometer is a measurement product that brings a colorimeter with excellent performance and convenient use to the market in a portable and compact manner. A portable spectrophotometer is a measurement product that brings a colorimeter with excellent performance and convenient use to the market in a portable and compact manner. It can be used for color measurement in industries such as automotive, new materials, new energy, plastics, leather, hardware, textiles, food, pharmaceutical R & D, and aviation. It is designed based on the spectroscopic principle, and the color separation colorimeter has high precision and increasing versatility. Since it can measure the reflectance curve at each wavelength, it is suitable for complex color analysis.

[0003] However, the existing spectrophotometers still have the following technical defects: 1. Their overall mass is relatively large, and it is very inconvenient to hold and operate them through the handle during testing; 2. Since the measurement port is flush with the base of the spectrophotometer, the measurement port needs to be pressed tightly against the surface of the object to be detected for measurement. Therefore, when the overall thickness of some detected objects is relatively thick, the base of the spectrophotometer cannot contact the workbench, resulting in the imbalance of the spectrophotometer, causing a gap between the measurement port and the detected object, and further affecting the measurement accuracy and effect. Summary of the Invention

[0004] The present invention aims to solve at least one of the problems existing in the related art to a certain extent. For this purpose, the present invention provides a horizontal spectrophotometer.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A horizontal spectrophotometer includes a housing and an optical structure assembly disposed inside the housing. A support boss seat is provided at the rear side of the lower end of the housing, and a measurement port is provided at the front side of the support boss seat. The optical structure assembly includes a reflecting mirror, a lens barrel, a spectrometer, and an integrating sphere.

[0025] The following specific implementation content provides multiple different embodiments or examples for implementing the present invention. Of course, these are only embodiments or examples and are not intended to be restrictive. Additionally, repeated reference numerals may be used in different embodiments, such as repeated numbers and / or letters. These repetitions are for the purpose of simply and clearly describing the present invention and do not represent a specific relationship between the different embodiments and / or structures discussed.

[0026] As Figures 1-6 shown, a horizontal spectrocolorimeter includes a housing 1 and an optical structure assembly disposed inside the housing 1. A support boss seat 2 is provided at the rear side of the lower end of the housing 1, and a measurement port 3 is provided at the front side of the support boss seat 2. The optical structure assembly includes a reflecting mirror 4, a lens barrel 5, a spectrometer 6, and an integrating sphere 7. The reflecting mirror 4, the lens barrel 5, and the spectrometer 6 are arranged in sequence from front to back. The integrating sphere 7 is disposed below the reflecting mirror 4, and the measurement port 3 is disposed below the reflecting mirror 4. A support base 8 is provided below the support boss seat 2, and an adjustable support device with adjustable support height is provided on the support base 8.

[0027] The horizontal spectrocolorimeter of the present invention first arranges the spectrometer 6 and the integrating sphere 7 at a 90° angle by using a reflecting mirror 4, so as to compress the overall height of the machine, make the entire optical structure assembly in a horizontal state, make rational use of the internal space of the housing 1, make the overall shape of the machine more compact, and facilitate the operation of the user.

[0028] In addition, an adjustable support device with adjustable support height is arranged on the support base 8, so that the support height can be adjusted according to the detection object 100 with different thicknesses. When the whole machine is supported on the workbench, the measurement port 3 is closely attached to the surface of the detection object 100, thereby improving the accuracy and effect of detection and measurement.

[0029] See Figures 3-5 As shown, the adjustable support device includes support foot assemblies arranged at intervals front and rear on the support base 8 and an adjustment drive assembly arranged between the two support foot assemblies. The support foot assembly includes a horizontal shaft 21 extending in the left-right direction. Support cam feet 22 are arranged at both the left and right ends of the horizontal shaft 21. The support cam feet 22 can swing out of the lower side of the support base 8 following the rotation of the horizontal shaft 21. The adjustment drive assembly is used to drive the horizontal shaft 21 to rotate.

[0030] Furthermore, the adjustment drive assembly includes an elliptical cam 31 rotatably arranged on the support base 8. The elliptical cam 31 is located between the two horizontal shafts 21 front and rear. A gear 32 is arranged on the horizontal shaft 21. Sliding frames 33 slide back and forth on both the front and rear sides of the elliptical cam 31. Rack bars 34 capable of meshing with the gear 32 are arranged on both the sliding frames 33. A tension spring 35 is connected between the two sliding frames 33. The sliding frames 33 are kept in abutting contact with the outer wall of the elliptical cam 31 under the action of the tension spring 35.

[0031] Furthermore, a worm gear 41 is arranged on the central axis of the elliptical cam 31. A rotating shaft 42 is rotatably installed on one side of the support base 8. A worm 43 capable of meshing with the worm gear 41 is arranged on the rotating shaft 42.

[0032] When the support cam feet 22 do not swing out and are located inside the support base 8, the support base 8 and the measurement port 3 are almost on the same horizontal plane, which is convenient for measuring objects with relatively thin thicknesses. When measuring a thicker detection object 100 (such as Figure 6As shown in the figure, by driving the rotation of the drive shaft 42, the worm 43 is engaged with the worm wheel 41 to rotate the elliptical cam 31. The rotation of the elliptical cam 31 pushes the sliding frames 33 on both sides, and drives the rack 34 to move outwards through the sliding frames 33. The rack 34 is engaged with the gear 32, thereby driving the rotation of the horizontal shaft 21. The rotation of the horizontal shaft 21 drives one end of the support cam foot 22 to swing outwards, and the whole machine is supported by the support cam foot 22. Thus, when the measurement port 3 is attached to the surface of the test object 100, the support cam foot 22 can also support on the workbench, enabling the whole machine to perform measurements in a balanced state, and improving the accuracy and effect of detection and measurement.

[0033] To facilitate the rotation of the drive shaft 42, one end of the worm 43 extends to the outside of the support base 8, and a knob 51 is fixedly provided.

[0034] Furthermore, an arc-shaped limit groove 61 is provided on the elliptical cam 31, and a limit post 62 is provided on the support base 8. The limit post 62 is arranged in the arc-shaped limit groove 61, so as to avoid excessive rotation of the elliptical cam 31 and improve the stability during operation.

[0035] In the horizontal spectrocolorimeter of the present invention, a battery compartment 71 and a battery cover 72 for covering the battery compartment 71 are provided on the support boss seat 2, and the support base 8 is arranged on the battery cover 72. By arranging the battery compartment 71 on the support boss seat 2, the space is reasonably utilized.

[0036] In the horizontal spectrocolorimeter of the present invention, concave recesses 81 are connected to the front side and the left and right sides of the housing 1, and an inclined portion 92 that inclines forward is provided at the rear side of the upper end of the housing 1; through the settings of the recesses 81 and the inclined portion 92, it is convenient for the operator to hold the instrument for operation, greatly improving the convenience.

[0037] To improve the aesthetics of the whole machine, decorative pieces are provided on the inner walls of the recesses 81.

Those skilled in the art should understand that the present invention is not limited by the above embodiments.
