[0016] Embodiments of the present utility model: Figures 1 to 6As shown, an infrared spectrophotometer for oil measurement comprises a main body 1 and a cover 2 which is connected or slidably connected to the main body 1. The cover 2 covers / exposes a colorimetric system area 3 on the main body 1 by rotating or sliding relative to the main body 1. The colorimetric system area 3 has a colorimetric slot 4 for placing a cuvette or a colorimetric tube. This is the prior art and will not be described in detail. The present application provides a closing component in the colorimetric system area 3. The closing component includes a closing member 5 and a spring 6. The spring 6 is the elastic member. The closing member 5 of the present application is slidably connected to the colorimetric system area 3 and connected to the spring 6. The spring 6 is connected to the main body 1. The closing member 5 has an inclined guide surface 11 which cooperates with the bottom of the cuvette or the colorimetric tube. When not in use, the cover 2 is in a position where the colorimetric system area 3 is covered. Figures 4 to 6 As shown, the closing member 5 is in a position to cover the notch of the colorimetric slot 4 under the action of the spring 6. When in use, the cover 2 is rotated to expose the colorimetric system area 3. The cuvette or colorimetric tube first contacts the inclined guide surface 11 of the closing member 5 during the process of moving down to enter the colorimetric slot 4, and the closing member 5 is pushed outward to expose the notch of the colorimetric slot 4, so that the cuvette or colorimetric tube can smoothly enter the colorimetric slot 4. In order to enable the cuvette or colorimetric tube to smoothly push the closing member 5 open, the closing member 5 and the spring 6 can be a pair of oppositely arranged ones, and the cuvette or colorimetric tube moves down from between the two closing members 5, so that the two closing members 5 move back to back to expose the notch of the colorimetric slot 4. It can also be as shown in the figure. Figures 1 to 3 As shown, a fixed blocking member 7 is provided on the opposite side of the closing member 5. When the closing member 5 is in a position covering the notch of the colorimetric slot 4, it contacts the blocking member 7. When the cuvette or colorimetric tube moves down from between the closing member 5 and the blocking member 7 into the colorimetric slot 4, the blocking member 7 limits one side of the cuvette or colorimetric tube, thereby forcing the closing member 5 on the other side to move to expose the notch of the colorimetric slot 4, so that the cuvette or colorimetric tube can smoothly enter the colorimetric slot 4. When the cuvette or colorimetric tube is in the colorimetric slot 4, the closing member 5 compresses the spring 6 during the outward movement, and the spring 6 generates an elastic force that pushes the closing member 5 to return to the initial position covering the notch of the colorimetric slot 4. The cuvette or colorimetric tube is in the colorimetric slot 4, and the closing piece 5 is in a state of clamping the cuvette or colorimetric tube between the closing piece 5 and the blocking piece 7 under the push of the elastic force. When the cuvette or colorimetric tube is taken out of the colorimetric slot 4, the closing piece 5 is reset to the initial position of covering the notch of the colorimetric slot 4 under the push of the elastic force, and the cuvette or colorimetric tube can realize the automatic opening and closing of the notch of the colorimetric slot 4 by plugging and unplugging, effectively preventing liquid from flowing into the colorimetric slot 4. Of course, the closing piece 5 can also be installed at the notch of the colorimetric slot 4 in a rotatable connection manner, and through cooperation with elastic parts such as torsion springs, the automatic opening and closing of the notch of the colorimetric slot 4 can be realized in a rotating form during the plugging and unplugging of the cuvette or colorimetric tube.

[0017] As a preferred embodiment, the closing component has a positioning mechanism that cooperates with the cuvette or colorimetric tube, specifically, the blocking member 7 has a sliding groove or blocking surface that slides with the cuvette or colorimetric tube, and limits the contact in three directions other than the side of the closing member 5, so as to better limit the cuvette or colorimetric tube, so that the cuvette or colorimetric tube can accurately and smoothly enter the colorimetric tank 4.

[0018] As a preferred embodiment, a plurality of supporting feet 8 are spirally connected to the bottom of the main body 1. The supporting feet 8 are located at the four corners of the main body 1. The height can be adjusted by rotating, and the main body can be stably placed on an uneven plane.

[0019] As a preferred embodiment, a handle 9 is provided on the main body 1, and both ends of the handle 9 are respectively connected to the two sides of the main body 1. When carrying the instrument, the handle 9 is rotated to the top of the main body 1, and it is convenient to move by holding the handle 9. When in use, the handle 9 is rotated to one side of the main body 1 without affecting the normal use of the instrument.
