Fig. 1 is a structural view of a water quality testing tube according to an embodiment of the present application. Fig. 2 is a partially enlarged view of a portion a in fig. 1.

The embodiment of the first aspect of the present application provides a test tube 100 for water quality detection, as shown in fig. 1, comprising an outer cylinder 200 and an inner cylinder 300, wherein the outer cylinder 200 is a part directly held by a detection person, and the inner cylinder 300 is a part actually containing water to be detected.

As shown in fig. 1 and 2, the outer cylinder 200 has a first end that is open and a second end that is closed, the second end is generally semi-spherical, and the inner wall of the outer cylinder 200 is provided with a clamping ring 210, and the clamping ring 210 is used for clamping the inner cylinder 300 to prevent the inner cylinder 300 from being largely tilted. The retainer ring 210 is provided with a vent hole 211, the vent hole 211 communicates the upper space and the lower space of the retainer ring 210, and silicone oil (not shown) is stored in the outer cylinder 200. The silicone oil is liquid at normal temperature and has good hydrophobicity.

The first end of the inner cylinder 300 is open, the second end is closed, the second end is generally semi-spherical, the first end of the inner cylinder 300 is provided with a flange 310, the outer wall of the inner cylinder 300 is abutted against the inner wall of the clamping ring 210 and the two can slide relatively to enable the flange 310 to be far away from or close to the first end of the outer cylinder 200, that is, the inner cylinder 300 can be inserted into the outer cylinder 200 and also can be pulled out of the outer cylinder 200. When the flange 310 abuts against the first end of the outer tub 200, the silicone oil contacts the lower surface of the clamp ring 210, that is, the portion of the outer wall of the inner tub 300 below the clamp ring 210 is submerged. Of course, silicone oil may also enter the vent holes 211, submerging the clamp ring 210 a portion as well.

It should be noted that the outer cylinder 200 and the inner cylinder 300 are generally made of transparent glass, which is convenient for observation and detection.

In contrast to the prior art, the water quality testing tube 100 has an outer tube 200 and an inner tube 300, and the inner tube 300 can be inserted into the outer tube 200 and also pulled out from the outer tube 200, and both are separated from each other. The outer cylinder 200 is provided at an inner wall thereof with a clamping ring 210, and the clamping ring 210 is used to clamp the inner cylinder 300. When the inner cylinder 300 is inserted into the outer cylinder 200, the outer wall of the inner cylinder 300 is abutted against the inner wall of the clamping ring 210, air below the clamping ring 210 can be discharged through the vent holes 211, the inner cylinder 300 is contacted with silicon oil along with the continuous insertion of the inner cylinder 300, the oil level of the silicon oil can be continuously raised, and when the flange 310 is abutted against the first end of the outer cylinder 200, the silicon oil is contacted with the lower surface of the clamping ring 210, so that the part of the inner cylinder 300, which is positioned below the clamping ring 210, is completely immersed, and the outer wall of the inner cylinder 300 is stained with the silicon oil. When the outer tube 200 is used, a tester holds the outer tube 200 to sample, and only impurities are adhered to the outer wall of the outer tube 200, and impurities are not adhered to the inner tube 300. After sampling, the inner cylinder 300 is taken out of the outer cylinder 200, a layer of silicon oil film is formed on the outer wall of the inner cylinder 300, and impurities are prevented from adhering to the inner cylinder 300 in the process of taking out detection, so that the influence of the impurities on the detection result is avoided, and the detection accuracy is improved.

In some embodiments, as shown in fig. 2, the upper surface of the clamping ring 210 is flush with the end surface of the first end of the outer cylinder 200, so that the space below the clamping ring 210 is maximized, the length of the silicon oil film formed on the outer wall of the inner cylinder 300 is maximized, and the effect of preventing impurities from adhering is the best.

To reduce the wear of the inner barrel 300 by the retaining ring 210, in some embodiments, the retaining ring 210 is made of a sponge, which is a soft material that causes little wear to the inner barrel 300, which can extend the useful life of the inner barrel 300. Meanwhile, when the silicone oil is in contact with the retaining ring 210, the silicone oil can be immersed into the retaining ring 210 (sponge), so that a silicone oil film can be formed in the process of pulling out the inner barrel 300 more conveniently.

It should be noted that, when the inner cylinder 300 is inserted into the outer cylinder 200, the sponge is radially compressed by the inner cylinder 300, so that the thickness of the sponge becomes thinner, and the size of the vent hole 211 also becomes smaller, and in design, it should be ensured that the vent hole 211 on the compressed sponge can still vent, so as to discharge the air under the clamping ring 210.

Fig. 3 is a sectional view of a water quality test tube according to another embodiment of the present application.

In order to facilitate the holding, in some embodiments, as shown in fig. 3, a holding sleeve 220 is disposed on an outer wall of the outer cylinder 200, and the holding sleeve 220 is generally made of rubber, so as to facilitate the holding by the inspector, increase the friction between the outer cylinder 200 and the hand of the inspector, and reduce the risk of the outer cylinder 200 falling off from the hand.

When the inner cylinder 300 is pulled out from the outer cylinder 200, a silicon oil film is formed. After the silicon oil is pulled out for many times, the volume of the silicon oil in the outer cylinder 200 is reduced, and the length of the outer wall of the inner cylinder 300 capable of forming a silicon oil film is also continuously reduced. In some embodiments, as shown in fig. 3, the outer wall of the outer cartridge 200 is provided with a lower limit oil level mark 230 and an upper limit oil level mark 240, the lower limit oil level mark 230 is located below the upper limit oil level mark 240, the lower limit oil level mark 230 is a position where the silicone oil just can contact the clip ring 210 after the inner cartridge 300 is inserted, and the upper limit oil level mark 240 is a position where the silicone oil does not overflow from the outer cartridge 200 after the inner cartridge 300 is inserted. Therefore, when in use, the liquid level of the silicone oil should be ensured to be between the lower limit oil level mark 230 and the upper limit oil level mark 240, so that the outer wall of the inner barrel 300 can form a silicone oil film and the silicone oil is prevented from overflowing from the outer barrel 200.

In some embodiments, the number of the vent holes 211 is multiple, and the plurality of vent holes 211 are uniformly distributed along the circumferential direction of the clamping ring 210, so that the ventilation efficiency is increased, and the air is prevented from being held back during the insertion of the inner barrel 300.

In some embodiments, the wall thickness of the gripping ring 210 is 3mm, so that there is sufficient clearance between the inner wall of the outer barrel 200 and the outer wall of the inner barrel 300 to avoid skew collision. The thickness here means a thickness when the clamp ring 210 is not pressed by the inner cylinder 300, and may be about 2mm after being pressed by the inner cylinder 300, and the size of the vent hole 211 may be reduced accordingly.

In some embodiments, the axial length of the gripping ring 210 is 10mm to 15 mm. Compared with the case that the axial length is less than 10mm, the axial length of the range is longer, the contact area of the clamping ring 210 and the inner cylinder 300 is larger, and the possibility of the inner cylinder 300 being skewed is lower. Compared with the condition that the axial length is larger than 15mm, the axial length in the range is smaller, the manufacturing material of the clamping ring 210 is less, the cost is lower, the friction force between the clamping ring 210 and the inner barrel 300 is also smaller, and the insertion and the extraction of the inner barrel 300 are more convenient.

FIG. 4 is a cross-sectional view of a turbidimeter provided in an embodiment of the present application. An embodiment of the second aspect of the present application provides a turbidity meter 400, as shown in fig. 4, including turbidity meter main body 410 and the test tube 100 for water quality detection of the first aspect, turbidity meter main body 410 is provided with a detection groove 411, a clamping member 412 is provided above detection groove 411, clamping member 412 clamps inner tube 300, and inner tube 300 stretches into in the detection groove 411.

Of course, the turbidimeter body 410 should also include a transmitting end and a receiving end for turbidity detection to measure turbidity by scattering method, which will not be described in detail herein.

Compared with the prior art, when the turbidity meter 400 is used for detecting, the water to be detected in the inner cylinder 300 of the first aspect is detected, the outer wall of the inner cylinder 300 can form a layer of silicon oil film, and the inner cylinder 300 is prevented from adhering impurities in the process of taking out the water to be detected, so that the influence of the impurities on a detection result is avoided, and the detection accuracy is improved.
