[0027] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0028] Example:

[0029] like Figure 1-4 As shown, this embodiment provides an ultramicro spectrophotometer with a protective mechanism, including an ultramicro spectrophotometer body 1; a movable seat 2, which is arranged in the ultramicro spectrophotometer body 1 and is used for adjusting the position of the detection test tube; a pull rod 3, which is arranged on the movable seat 2 and is used to pull the movable seat 2 to adjust the position of the movable seat 2; a test tube sleeve 4, which is arranged above the movable seat 2 and is used for plugging the detection test tube; a protective component 5, which is arranged on the ultramicro spectrophotometer body 1 and is used to prevent dust from entering the ultramicro spectrophotometer body 1 and protecting the detection test tube to prevent the sample from overflowing when the detection test tube is pulled; an operation button 6, which is arranged on the ultramicro spectrophotometer body 1 and is used for operating the ultramicro spectrophotometer body 1; a button protective cover 7, which is arranged on the operation button 6 and is used to protect the operation button 6; a cleaning component 8, which is arranged on the ultramicro spectrophotometer body 1 and the protective component 5, and is used for cleaning and collecting dust;

[0030] Open the protective assembly 5, insert the test tube to be tested into the test tube sleeve 4, and then close the protective assembly 5. Pull the movable seat 2 by the pull rod 3 to adjust the position of the test tube so that the test tube is irradiated with light waves of different wavelengths. When the test tube is pulled, the protective assembly 5 rests on the opening of the test tube to prevent the test liquid in the test tube from overflowing and causing contamination in the ultra-micro spectrophotometer body 1. When the ultra-micro spectrophotometer body 1 is not in use, the protective assembly 5 covers the ultra-micro spectrophotometer body 1. , which can prevent dust from entering the ultra-micro spectrophotometer body 1. When the protection component 5 is opened, the cleaning component 8 will clean and collect the dust accumulated on the surface of the protection component 5. When the ultra-micro spectrophotometer body 1 is operated, the button protection cover 7 can protect the control button 6. When the pressing force is too large, the button protection cover 7 rests on the surface of the ultra-micro spectrophotometer body 1, preventing the control button 6 from malfunctioning and being damaged due to excessive pressing force, and at the same time preventing the control button 6 from being scratched by fingernails during operation.

[0031] In one embodiment, the protective assembly 5 includes a movable member 51 disposed above the movable base 2, the test tube sleeve 4 is mounted on the movable member 51, a spring 52 is mounted on the movable base 2, the other end of the spring 52 is mounted on the bottom of the movable member 51, and a protective plate 53 is slidably mounted on the ultra-micro spectrophotometer body 1, the protective plate 53 is provided with a curved surface 54, and a liquid absorbing pad 55 is mounted on the protective plate 53;

[0032] When the ultra-micro spectrophotometer body 1 needs to be protected from dust and the test tube needs to be protected from overflow, the protective plate 53 is moved rightward. When the curved surface 54 on the protective plate 53 contacts the top of the test tube, the test tube is moved downward by the action of the curved surface 54. The downward movement of the test tube also drives the movable member 51 downward. At this time, the protective plate 53 is also compressed. When the protective plate 53 is continued to be moved, the opening of the test tube is pressed against the liquid absorbing pad 55. When the test tube is pulled, the liquid in the test tube is prevented from overflowing. On the other hand, the protective plate 53 covers the ultra-micro spectrophotometer body 1, which also prevents dust from entering the ultra-micro spectrophotometer body 1.

[0033] In one embodiment, specifically, the protection assembly 5 further includes a damper 56 mounted on the movable seat 2 , a pressing block 57 is mounted on the movable member 51 , and the top end of the damper 56 is mounted on the pressing block 57 ;

[0034] When the test tube needs to be taken out, the protective plate 53 is pulled open. Under the action of the damper 56, the pressing block 57 will drive the movable part 51 to rise slowly, thereby driving the test tube to rise slowly, preventing the test tube from directly popping up and causing liquid overflow.

[0035] In one embodiment, specifically, the protection assembly 5 further includes a first guide groove 58 provided on the ultra-micro spectrophotometer body 1, a second guide groove 59 being provided on the inner wall of the first guide groove 58, a first guide block 510 being mounted on the protection plate 53, a second guide block 511 being mounted on the first guide block 510, a shift block 512 being mounted on the second guide block 511, the first guide block 510 being slidably mounted in the first guide groove 58, and the second guide block 511 being slidably mounted in the second guide groove 59;

[0036] The first guide groove 58 can guide the movement of the protective plate 53. The operator can pinch the shift block 512 and move the second guide block 511 and the first guide block 510 by shifting the shift block 512, thereby driving the protective plate 53 to move and open or close the protective plate 53. The second guide groove 59 can guide the movement of the second guide block 511.

[0037] In one embodiment, the protective assembly 5 further includes an insertion rod 513 mounted on the protective plate 53. A slot 514 is provided on the ultra-micro spectrophotometer body 1. The insertion rod 513 fits into the slot 514. A magnet block 515 is installed in the slot 514. An iron block 516 is installed on the insertion rod 513.

[0038] When the protection plate 53 needs to be positioned, the protection plate 53 moves to the right, which drives the insertion rod 513 into the slot 514. At this time, the magnet block 515 is attracted to the iron block 516, which can play a role in positioning the protection plate 53.

[0039] In one embodiment, specifically, the cleaning assembly 8 includes an elastic strip 81 mounted on the ultra-micro spectrophotometer body 1 , a cleaning wipe 82 is mounted on the elastic strip 81 , and a collection box 83 is provided in the ultra-micro spectrophotometer body 1 ;

[0040] When the dust accumulated on the surface of the protective plate 53 needs to be cleaned, the protective plate 53 moves to the right and the cleaning wipe 82 on the elastic strip 81 wipes the surface of the protective plate 53, and the dust generated by wiping falls into the collection box 83 for collection.

[0041] Working principle: When in use, the operator can pinch the dial block 512 and lift the elastic strip 81 and the cleaning wipe 82 upwards, and by dialing the dial block 512, the second guide block 511 and the first guide block 510 are moved to move the protective plate 53 to the left, and the test tube to be tested is inserted into the test tube sleeve 4, and then the protective plate 53 is moved to the right. When the arc surface 54 on the protective plate 53 contacts the top of the test tube, the test tube is driven to move downward under the action of the arc surface 54, and the downward movement of the test tube drives the movable part 51 to move downward. At this time, the protective plate 53 is also compressed, and the protective plate 53 is continued to be moved. At this time, the opening of the test tube is against the liquid absorbing pad 55. When pulling the test tube, the movable seat 2 is pulled by the pull rod 3 to adjust the position of the test tube so that the test tube Irradiation with light waves of different wavelengths can prevent the liquid in the test tube from overflowing. On the other hand, the protective plate 53 covering the ultra-micro spectrophotometer body 1 can also prevent dust from entering the ultra-micro spectrophotometer body 1. On the other hand, when the protective plate 53 moves to the right, the elastic strip 81 and the cleaning wipe 82 are loosened, and the cleaning wipe 82 on the elastic strip 81 will wipe the surface of the protective plate 53. The dust generated by wiping will fall into the collection box 83 for collection. When the ultra-micro spectrophotometer body 1 is operated, the button protective cover 7 can protect the control button 6. When the pressing force is too great, the button protective cover 7 rests on the surface of the ultra-micro spectrophotometer body 1 to prevent the control button 6 from malfunctioning and being damaged due to excessive pressing force, and at the same time, it can prevent the control button 6 from being scratched by fingernails during operation.
