Description

Technical Field

[0001] The utility model belongs to the technical field of water quality detection, in particular to an online water quality nitrite detector. Background Art

[0002] Nitrite is a salt containing nitrite anions (NO2-). The most common is sodium nitrite, which is a white to light yellow powder or granules with a slightly salty taste and is easily soluble in water. Nitrates and nitrites are widely present in the human environment and are the most common nitrogen-containing compounds in nature. The probability of food poisoning caused by nitrite is relatively high. Ingestion of 0.3 to 0.5 grams of nitrite can cause poisoning, and 3 grams can cause death. In order to detect the nitrite content in food, a detector is required for numerical detection;

[0003] When existing equipment is testing the material in the test tube, the test tube may be displaced due to shaking or touching, resulting in inaccurate subsequent testing results. At the same time, the test tube will be exposed to the outside world during testing, causing dust to enter the test object, requiring re-testing, and complex operations are required to install the test tube that needs to be tested later. Therefore, we proposed an online water quality nitrite detector. Utility Model Content

[0004] The purpose of the utility model is to provide an online water quality nitrite detector. Through the detector, the problem of existing equipment that when testing materials in the test tube, the test tube will be displaced due to shaking or touching, resulting in inaccurate subsequent detection results, and the test tube will be exposed to the outside world during testing, causing dust to enter the inside of the test object, requiring re-testing, and complex operations are required to install the test tube that needs to be tested subsequently.

[0005] In order to solve the above technical problems, the present invention is achieved through the following technical solutions:

[0006] The utility model is an online water quality nitrite detector, comprising a detector, a bottom outer wall of the detector being fixedly connected to a plurality of supporting legs, a top inner wall of the detector being fixedly connected to a display panel, a top inner wall of the detector being fixedly connected to a plurality of operation buttons, a detection cavity being provided on the inner wall of one end of the detector away from the display panel, a plurality of fixing ears being fixedly connected to the top outer wall of the detector, and a fixed shaft being fixedly connected to the center axis of the outer wall of the fixing ear.

[0009] Furthermore, the inner wall of the placement plate is provided with a plurality of placement grooves, the inner walls of the placement grooves are fixedly connected with a plurality of extrusion springs, and the outer walls of the extrusion springs are fixedly connected with a clamping plate.

[0010] Furthermore, the inner wall of the placement plate is provided with a plurality of connection grooves, the inner wall of the connection groove is fixedly connected with a plurality of springs, the outer wall of the spring away from the clamping plate is fixedly connected with a clamping plate, and the clamping plate is fitted with the connection groove.

[0011] Furthermore, the inner wall of the detector is provided with a plurality of slots, the inner wall of the detector is provided with a plurality of movable cavities, and the inner wall of the movable cavity is slidably connected with a push-pull plate.

[0012] Furthermore, a top block is fixedly connected to the outer wall of one end of the push-pull plate close to the clamping plate, and the top block has the same size as the clamping slot. A plurality of springs 2 are fixedly connected to the outer wall of the push-pull plate, and the springs 2 are fixedly connected to the inner wall of the detector.

[0013] The utility model has the following beneficial effects:

[0014] 1. The utility model is provided with a placement slot in the detector. When the equipment needs to be used, the test tube to be tested is placed in the placement slot. When the test tube is placed, the clamping plate will push the clamping plate to both sides. When the clamping plate is pushed, multiple extrusion springs will be compressed. Then, the clamping plate will be pushed due to the rebound force of the multiple extrusion springs to clamp the test tube inside the placement slot. Then, the test tube is pressed down to make the placement plate move downward as a whole. During the movement, multiple compression springs will begin to be squeezed. Then, when the clamping plate is fitted in the clamping slot, it will be quickly popped out by the multiple springs to clamp the clamping plate in the clamping slot, so that the test tube to be tested can be quickly clamped to prevent displacement during detection and inaccurate detection results.

[0015] 2. The utility model is provided with a handle on the dust cover. When the equipment is in use, the handle is pulled to rotate the dust cover, closing the detection chamber as a whole, starting the support legs to detect the material inside through the detection plate, and then after the detection is completed, multiple push-pull plates are moved to slide in the movable cavity to squeeze multiple springs and push the top block to start pushing the clamping plate forward. When the clamping plate is pushed, multiple springs are compressed to slide it into the connecting groove, so that the equipment can be closed when testing the material to prevent dust from entering the material and causing the detection effect to deteriorate, thereby requiring re-testing. At the same time, the test tube can be quickly fitted to the equipment, and the equipment can be quickly reset to prepare for the next test.
