Description

Technical Field

[0001] The utility model relates to the technical field of nitrite detection equipment, in particular to a nitrite rapid detector. Background Art

[0002] The handheld nitrite detector is a water quality detection instrument that integrates modern biotechnology and optical technology. It can quickly analyze the nitrite content in the sample. The instrument uses a special filter and a professional detection light source, and does not require complicated laboratory operations. It is widely used to monitor the nitrite content in natural water sources such as tap water, river water, lake water, as well as production water sources, wastewater discharge outlets, etc.

[0003] When a water sample is tested by a nitrite detector, a certain amount of water sample is selected and put into a colorimetric bottle, and after adding reagents into the colorimetric bottle, the colorimetric bottle is placed in the detection tank of the nitrite detector, so that the absorbance of the generated rose-red azo compound is measured by the internal spectrophotometer, and according to the proportional relationship between the absorbance and the nitrite content, the nitrite detector can automatically calculate the specific content of nitrite in the water sample. When the existing colorimetric bottle is placed in the detection tank of the nitrite detector for testing, in order to ensure the accuracy of the test data, the entire body of the colorimetric bottle needs to be inserted into the detection tank, so only the bottle cap of the colorimetric bottle is exposed outside. When taking the colorimetric bottle, due to the low height of the bottle cap of some colorimetric bottles, it is easy to cause the fingers to be unable to quickly pinch the colorimetric bottle when taking this type of colorimetric bottle, and it is easy for the fingers and the bottle cap of the colorimetric bottle to slide and separate when extracting the colorimetric bottle, which brings inconvenience to taking the colorimetric bottle.

DETAILED DESCRIPTION

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-Figure 4As shown, the nitrite rapid detector provided by the utility model includes a detector body 1, a charging port 2 is fixedly installed on one side of the detector body 1, a touch screen 3 is fixedly installed on the detector body 1, a sinking groove 4 is opened on the detector body 1 near the touch screen 3, a bottle barrel 5 is fixedly installed on the bottom of the sinking groove 4, a detection mechanism mounting tube 6 is fixedly installed on the outside of the bottle barrel 5, a first mounting groove 7 is opened on one side of the sinking groove 4, a second mounting groove 8 is opened on the bottom of the first mounting groove 7, a sliding hole 18 is opened on the bottom of the second mounting groove 8, a slider 9 is movably installed in the second mounting groove 8, a push rod 10 is fixedly installed on the lower end of the slider 9, one end of the push rod 10 passes through the sliding hole 18 and extends into the detector body 1 and is fixedly installed with a top block 11, a rotating shaft 13 is fixedly installed in the sinking groove 4 above the first mounting groove 7, a top cover 12 is arranged on the rotating shaft 13, a shaft sleeve 14 is fixedly installed on one side of the top cover 12, and the top cover 12 is rotatably connected to the rotating shaft 13 through the shaft sleeve 14.

[0023] like Figure 3 As shown, a push-in slot 19 is provided on the side of the bottle barrel 5 which is away from the detection mechanism mounting tube 6 , and the bottle barrel 5 can store and detect colorimetric bottles, and the opening of the push-in slot 19 provides conditions for the insertion of the ejector block 11 .

[0024] like Figure 2-Figure 4 As shown, guide strips 17 are fixedly installed on both sides of the second mounting groove 8, a sliding hole 18 is provided at the bottom of the second mounting groove 8, a pressure block 20 is fixedly installed on the top of the slider 9, and sliding grooves 21 are provided on both sides of the slider 9. The slider 9 is inserted into the second mounting groove 8, and the sliding grooves 21 are also slidably connected to the corresponding guide strips 17, and the pressure block 20 is placed in the first mounting groove 7. The longitudinal section of the top block 11 is an unequal-sided triangle, and a first pressure portion 15 is fixedly installed at the bottom of the top cover 12, and the bottom of the first pressure portion 15 has a slope, and a second pressure portion 16 is fixedly installed in the middle of one side of the top cover 12. When the top cover 12 is opened, the first pressure portion 15 can be used to apply pressure to the pressure block 20, so that the slider 9, the push rod 10, and the top block 11 are inserted into the bottle tube 5 to lift the colorimetric bottle, thereby facilitating the removal of the colorimetric bottle.

[0025] It should be noted that the utility model is a rapid nitrite detector. After the colorimetric bottle containing the water sample is inserted into the bottle barrel 5, the bottom of the colorimetric bottle will be restricted by the top block 11 and cannot continue to move downward. At this time, there is no need to press down the colorimetric bottle. The top cover 12 can be directly rotated on the shaft 13 with the shaft sleeve 14 as the axis to close it, so that the top cover 12 drives the first pressure-applying part 15 to turn over synchronously and move out of the first mounting groove 7. At this time, conditions are provided for the upward movement of the pressure block 20. When the top cover 12 completely covers the sinking groove 4, the second pressure-applying portion 16 gradually presses the colorimetric bottle downward, so that the colorimetric bottle moves downward in the bottle tube 5 and squeezes the top block 11 to one side, so that the top block 11 drives the push rod 10 to move upward in the sliding hole 18, and makes the top block 11 gradually move out of the top-input through groove 19, so that the top block 11 drives the slider 9 to move upward in the guide bar 17, and synchronously, the slider 9 drives the pressure block 20 to move upward in the first installation groove 7, and the insertion of the colorimetric bottle can be completed;

[0026] Subsequently, the detection mechanism in the detector body 1 can be controlled by the touch screen 3 on the detector body 1 to detect the water sample in the colorimetric bottle. When the detection is completed, the top cover 12 can continue to rotate and open on the shaft 13 with the shaft sleeve 14 as the axis, so that the top cover 12 gradually drives the first pressure-applying part 15 to move into the first mounting groove 7, so that the pressure block 20 is pressed down by the slope at the bottom of the first pressure-applying part 15, and then the pressure block 20 drives the push-in slider 9 to move downward in the first mounting groove 7, and the slider 9 drives the push block 11 to be gradually inserted into the push-in groove 19 through the push rod 10, so that the bottle barrel 5 is pushed up by the slope on one side of the push block 11, so that the bottle barrel 5 can be pushed up to a certain height synchronously when the top cover 12 is opened, thereby facilitating the removal of the colorimetric bottle.

[0027] The above shows and describes the basic principle and main features of the utility model and the advantages of the utility model.
