[0002] UV-visible-near-infrared spectrophotometer is a high-performance wide-spectrum spectrophotometer, and there are two main series on the market: 5000 and 3000. The instrument adopts the latest materials and processes, and with its excellent mechanical and optical performance and stable and accurate hardware acquisition circuit, the whole machine has reached the international advanced level of similar products. Among them, the 5000 series products are mainly used for the measurement of optical properties of transmission, reflection and diffuse reflection of solid, thin film materials, chemical liquid materials and powder samples, and are mainly used in colleges and universities and scientific research institutes. The 3000 series products are mainly aimed at the architectural glass market, meeting the current market demand for glass materials to measure and verify the optical properties of materials such as light transmittance, reflectance, shading coefficient, heat gain coefficient and solar reflectance, and are mainly used in architectural instrument testing stations and metrology institutes.

[0003] Most of the existing UV-visible-near-infrared spectrophotometer filters are manufactured together and directly spliced ​​before leaving the market, which makes it inconvenient for users to replace and disassemble them. In addition, the angle of the existing UV-visible-near-infrared spectrophotometer filters cannot be adjusted. If the angle of the filter needs to be adjusted, the entire machine needs to be moved, which is very troublesome. Therefore, it is necessary to propose a UV-visible-near-infrared spectrophotometer filter that can solve the above problems. Utility Model Content

[0005] The angle adjustment structure includes a U-shaped frame A, a motor, a rotating shaft, a connecting block A, an electric push rod, a U-shaped frame B, a connecting shaft, and a connecting block B. The U-shaped frame A is connected to the motor, the motor is connected to the rotating shaft, the connecting block A is arranged on the rotating shaft, the connecting block A is connected to the electric push rod, the electric push rod is connected to the U-shaped frame B, the U-shaped frame B is arranged with a connecting shaft, the connecting shaft is arranged with a connecting block B, and the connecting block B can rotate on the connecting shaft.

[0006] Beneficial effects of the utility model:

[0007] The utility model can place the structure at the filter installation location, hold the connecting column and rotate it, so that the thread of the installation ring is screwed down along the installed thread, and the structure is installed. The utility model can disassemble and assemble the filter separately, which greatly facilitates the staff to replace filters of different models and inspect the filters.

[0008] The utility model rotates the motor and the shaft, thereby driving the connecting block A and the components thereon to rotate, and the corresponding electric push rod extends or retracts, thereby compensating for the distance difference generated when the filter is adjusted in angle, thereby adjusting the filter to a suitable angle. The utility model can adjust the angle of the filter without moving the entire machine, which greatly facilitates the use of the staff. BRIEF DESCRIPTION OF THE DRAWINGS
