[0006] Preferably, a cover plate is hinged and rotatably connected above the detection cavity of the main body of the fluorescence quantitative analyzer. A baffle that abuts against the end of one of the arc-shaped masks is fixedly connected to the inner wall of the other arc-shaped mask. An arc-shaped block is fixedly connected to the bottom end of the arc-shaped mask. The arc-shaped block is specifically a T-shaped structure. A T-shaped annular groove that cooperates with the arc-shaped block is opened on the bottom side of the detection cavity of the main body of the fluorescence quantitative analyzer.

[0010] Beneficial effects

[0011] This invention provides a fluorescence quantitative analyzer that facilitates the replacement of the light-absorbing layer. Compared with the prior art, it has the following advantages:

[0012] (1) The fluorescence quantitative analyzer with easy replacement of light-absorbing layer is equipped with a protective component, which includes a first protective cover and a second protective cover. The combined curvature of the two arc-shaped masks is greater than 360°, so that when the detection chamber is closed, the ends of the two arc-shaped masks will intersect each other. The arc-shaped masks are equipped with light-absorbing components. Therefore, if there is a gap when the two arc-shaped masks are locked together, the light-absorbing layer can absorb the light entering, thereby reducing the intensity of the light entering the detection chamber and thus reducing the impact on the detection data.

[0013] (2) The fluorescence quantitative analyzer that facilitates the replacement of the light-absorbing layer has a placement cavity on the arc-shaped mask, in which the light-absorbing component is inserted. The top of the detection cavity in the main body of the fluorescence quantitative analyzer penetrates the main body of the fluorescence quantitative analyzer, and a cover plate is hinged at the penetration point. When it is necessary to replace the light-absorbing component, simply rotate to open the cover plate, rotate the arc-shaped mask to expose the light-absorbing component, and then easily pull out the light-absorbing component.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-4 This utility model provides a technical solution: a fluorescence quantitative analyzer with easy replacement of the light-absorbing layer, including a fluorescence quantitative analyzer body 1. A protective component 2 is rotatably arranged inside the detection cavity of the fluorescence quantitative analyzer body 1. The protective component 2 includes a first protective cover 21 and a second protective cover 22. Both the first protective cover 21 and the second protective cover 22 include an arc-shaped mask 211. The arc of the two arc-shaped masks 211 is greater than 360°. The outer wall of one arc-shaped mask 211 is attached to the inner wall of the other arc-shaped mask 211. A placement cavity 215 is opened at the top of the arc-shaped mask 211. A light-absorbing component 23 is slidably inserted into the placement cavity 215.

[0021] Specifically, by setting up a protective component 2, which includes a first protective cover 21 and a second protective cover 22, the curvature of the two arc-shaped masks 211 is greater than 360°, so that when the detection cavity is closed, the ends of the two arc-shaped masks 211 will intersect each other. A light-absorbing component 23 is set inside the arc-shaped mask 211, so that if there is a gap when the two arc-shaped masks 211 are locked together, the light-absorbing layer can absorb the light entering, thereby reducing the intensity of the light entering the detection cavity and thus reducing the impact on the detection data.

[0022] The curved mask 211 has a placement cavity 215, and the light-absorbing component 23 is inserted into the placement cavity 215. The top of the detection cavity in the main body 1 of the fluorescence quantitative analyzer penetrates the main body 1 of the fluorescence quantitative analyzer, and a cover plate is hinged at the penetration point. When it is necessary to replace the light-absorbing component 23, simply rotate to open the cover plate, rotate the curved mask 211 to expose the light-absorbing component 23, and then you can easily pull out the light-absorbing component 23.

[0023] A cover plate is hinged and rotatably connected above the detection chamber of the main body 1 of the fluorescence quantitative analyzer. A baffle 212 is fixedly connected to the inner wall of another arc-shaped mask 211, which abuts against the end of one of the arc-shaped masks 211. An arc-shaped block 213 is fixedly connected to the bottom end of the arc-shaped mask 211. The arc-shaped block 213 is specifically a T-shaped structure. A T-shaped annular groove 11 that cooperates with the arc-shaped block 213 is opened on the bottom side of the detection chamber of the main body 1 of the fluorescence quantitative analyzer.

[0024] Specifically, the rotation of the cover plate allows the light-absorbing component 23 located on the front of the detection cavity to be exposed when the arc-shaped mask 211 is rotated. The cooperation of the arc-shaped block 213 and the T-shaped annular groove 11 enables the arc-shaped mask 211 to rotate stably, thereby reducing the shaking between them when the arc-shaped mask 211 rotates, thus avoiding or reducing the occurrence of gaps, thereby reducing the intensity of light entering the detection cavity through the gaps.

[0025] The light-absorbing component 23 includes a first light-absorbing layer 231 with an arc-shaped structure. A fixing block 232 that abuts against the top of the arc-shaped mask 211 is fixedly connected to the top of the first light-absorbing layer 231. A rubber block 233 that fits against the side of the arc-shaped mask 211 is fixedly connected to the side of the fixing block 232. A knob 234 is threadedly connected to the side of the rubber block 233. The end of the knob 234 abuts against the side of the arc-shaped mask 211.

[0026] Specifically, the fixing block 232 has an arc-shaped structure to fix the shape of the first light-absorbing layer 231. When the fixing block 232 is pulled, the first light-absorbing layer 231 can be pulled out simultaneously for easy disassembly. The rubber block 233 fits against the side of the arc-shaped mask 211 to increase the friction between them, so that the first light-absorbing layer 231 can be easily disassembled and installed.

[0027] An L-shaped groove 214 is provided at the end of the arc-shaped mask 211. A second light-absorbing layer 24 is slidably inserted into the L-shaped groove 214. The second light-absorbing layer 24 is specifically an L-shaped structure. The bottom end of the first light-absorbing layer 231 and the vertical end of the second light-absorbing layer 24 are intersected.

[0028] Specifically, the horizontal end of the L-shaped groove 214 is located inside the arc-shaped block 213, and the vertical end is located inside the arc-shaped mask 211. This prevents a gap from being left between the bottom end of the first light-absorbing layer 231 and the bottom end of the arc-shaped mask 211 when the first light-absorbing layer 231 is inserted into the arc-shaped mask 211, thus preventing light from entering the detection cavity through the gap between the first light-absorbing layer 231 and the bottom end of the arc-shaped mask 211.

[0029] A locking device 3 is provided on the side of the main body 1 of the fluorescence quantitative analyzer. The locking device 3 includes a fixing bolt 31 that is threadedly connected to the main body 1 of the fluorescence quantitative analyzer. The end of the fixing bolt 31 extends into the detection chamber and abuts against the outer wall of another arc-shaped mask 211.

[0030] Specifically, the locking device 3 fixes another arc-shaped mask 211 during testing, thereby fixing the position of the protective component 2 during testing.
