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.

[0018] like Figure 1-Figure 6 A horizontal spectrophotometer shown in the figure includes a shell 1 and an optical structure component arranged in the shell 1, a support boss seat 2 is arranged on the rear side of the lower end of the shell 1, and a measuring port 3 is arranged on the front side of the support boss seat 2. The optical structure component includes a reflector 4, a lens barrel 5, a spectrometer 6 and an integrating sphere 7. The reflector 4, the lens barrel 5 and the spectrometer 6 are arranged in sequence from front to back, the integrating sphere 7 is arranged on the lower side of the reflector 4, the measuring port 3 is arranged on the lower side of the reflector 4, a support base 8 is arranged on the lower side of the support boss seat 2, and an adjustable support device with adjustable support height is arranged on the support base 8.

[0019] The horizontal spectrophotometer of the present invention firstly uses a reflector 4 to set the spectrometer 6 and the integrating sphere 7 at 90 degrees, thereby achieving the compression of the height of the whole machine, making the whole optical structure component in a horizontal state, thereby reasonably utilizing the internal space of the shell 1, making the appearance of the whole machine more compact, and facilitating user operation.

[0020] In addition, by providing an adjustable support device with adjustable support height on the support base 8, the support height can be adjusted according to the different thicknesses of the detection object 100, so that when the whole machine is supported on the workbench, the measuring port 3 can be tightly attached to the surface of the detection object 100, thereby improving the accuracy and effect of the detection and measurement.

[0021] See also Figure 3-Figure 5 As shown, the adjustable support device includes a support foot assembly arranged on the support base 8 with a front-to-rear interval and an adjustment drive assembly arranged between the two support foot assemblies, the support foot assembly includes a horizontal axis 21 extending along the left-right direction, and support cam feet 22 are arranged on the left and right ends of the horizontal axis 21. The support cam feet 22 can follow the rotation of the horizontal axis 21 and swing outward from the lower side of the support base 8, and the adjustment drive assembly is used to drive the horizontal axis 21 to rotate.

[0022] 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 front and rear transverse axes 21, a gear 32 is on the transverse axis 21, and sliding frames 33 are slid forward and backward on both sides of the front and rear of the elliptical cam 31, and racks 34 that can mesh with the gear 32 are arranged on the two sliding frames 33, and a tension spring 35 is connected between the two sliding frames 33, and the sliding frame 33 is kept against and fitted against the outer wall of the elliptical cam 31 by the action of the tension spring 35.

[0024] When the support cam foot 22 is not swung outward and is located in the support base 8, the support base 8 and the measuring port 3 are almost on the same horizontal plane, and the test can be convenient for measuring thinner objects. Figure 6 As shown), by driving the rotating shaft 42 to rotate, the worm 43 cooperates 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 the racks 34 are driven to move outward through the sliding frames 33. The racks 34 are meshed with the gears 32, thereby driving the horizontal axis 21 to rotate. The rotation of the horizontal axis 21 drives one end of the supporting cam foot 22 to swing outward, and the whole machine is supported by the supporting cam foot 22. Therefore, when the measuring port 3 is attached to the surface of the detection object 100, the supporting cam foot 22 can also be supported on the workbench, so that the whole machine can be measured in a balanced state, thereby improving the accuracy and effect of the detection and measurement.
