[0002] Chemical experiments are experiments in which chemical reactions occur. Test tubes are commonly used instruments in chemical laboratories and are used as reaction containers for small amounts of reagents. After cleaning, test tubes can be placed on test tube racks for easy storage and drying.

[0003] In the process of chemical reagent testing, it is necessary to test a variety of different reagents. During the test, the test tubes are placed on the test rack to wait for the reaction. Due to the uncertainty of the test results, the test reagents may overflow from the test tubes during the test, causing contamination to the table. In order to address this technical problem, this application proposes a test tube support structure for chemical reagent testing. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a test tube support structure for chemical reagent testing. The shield can be snapped onto the inner wall of the limiting ring to shield the test tube opening while leaving gaps for gas flow to ensure the reagent testing environment. When reagent overflows, the shield can block and guide it, allowing the reagent to flow down the outer wall of the test tube and eventually enter the collection tank, thus avoiding contamination or interference with the testing of other reagents.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A test tube holder structure for chemical reagent detection includes a base, a collection groove fixedly connected to the top of the base, a partition fixedly connected to the inner wall of the collection groove, fixing plates fixedly connected to the left and right sides of the top of the base, a first horizontal plate fixedly connected to the front side of one end of the fixing plate, a plurality of support seats provided on the inner wall of the first horizontal plate, a second horizontal plate fixedly connected to the upper side of the first horizontal plate on the front side of one end of the fixing plate, a plurality of limiting rings fixedly connected to the inner wall of the second horizontal plate, a support assembly provided on the rear side of one end of the fixing plate, and an auxiliary assembly provided at the rear end of the fixing plate.

[0007] Furthermore, a water inlet pipe is provided on the left side of the front end of the collection tank, and a small water pump is provided on the outer wall of the water inlet pipe. A drain pipe is provided on the right side of the front end of the collection tank.

[0008] Furthermore, the support assembly includes a fourth horizontal plate fixedly connected to the rear side of the opposite end of the fixed plate, and a third horizontal plate fixedly connected to the upper side of the fourth horizontal plate at the rear side of the opposite end of the fixed plate.

[0009] Furthermore, the top of both the third and fourth horizontal plates are provided with multiple holes, and the inner wall of the hole at the top of the fourth horizontal plate is provided with a limiting block.

[0010] Furthermore, the auxiliary component includes an air outlet fixedly connected to the rear end of the fixed plate, an air supply pipe passing through the rear end of the air outlet, and a fan fixedly connected to the other end of the air supply pipe.

[0011] Furthermore, the bottom end of the fan is fixedly connected to the top of the base, and the air outlet is used to blow air onto the test tube opening at the bottom of the fourth horizontal plate.

[0012] Furthermore, each of the limiting rings has a shielding cover attached to its inner wall, which is used to shield the test tube opening at the top of the third horizontal plate.

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

[0014] 1. In this utility model, the shield can be snapped onto the inner wall of the limiting ring to shield the mouth of the test tube, while leaving gaps for gas flow to ensure the reagent detection environment.

[0021] 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.

[0022] Reference Figure 1-3 An embodiment of this utility model provides a test tube support structure for chemical reagent detection, including a base 1, a collection tank 5 fixedly connected to the top of the base 1, a partition 6 fixedly connected to the inner wall of the collection tank 5, a water inlet pipe 3 passing through the left front end of the collection tank 5, a small water pump 4 being provided on the outer wall of the water inlet pipe 3, a drain pipe 7 passing through the right front end of the collection tank 5, a fixing plate 2 fixedly connected to both the left and right sides of the top of the base 1, a first horizontal plate 8 fixedly connected to the front side of the opposite end of the fixing plate 2, a plurality of support seats 9 being provided on the inner wall of the first horizontal plate 8, a second horizontal plate 10 fixedly connected to the upper side of the first horizontal plate 8 corresponding to the front side of the opposite end of the fixing plate 2, a plurality of limiting rings 17 fixedly connected to the inner wall of the second horizontal plate 10, and a shielding cover 11 being snapped into the inner wall of each limiting ring 17, the shielding cover 11 being used to shield the test tube opening at the top of the third horizontal plate 12;

[0023] Specifically, the test tube to be tested can be placed on the support seat 9 on the first horizontal plate 8, and the upper side of the outer wall of the test tube is limited by the limiting ring 17 on the second horizontal plate 10, so that the test tube can be kept vertical and the possibility of reagent overflowing the test tube in case of accidental detection can be reduced. The shield 11 can be snapped into the inner wall of the limiting ring 17 to shield the mouth of the test tube, while leaving gaps for gas flow to ensure the reagent detection environment. When reagent overflows, the shield 11 can shield and guide it, so that the reagent flows down the outer wall of the test tube and finally enters the collection tank 5. After being mixed with clean water through the water inlet pipe 3, it is discharged through the drain pipe 7 for treatment. The baffle 6 installed on the collection tank 5 can prevent foreign objects from falling into the collection tank 5 and causing blockage of the drain pipe 7, which would affect the liquid discharge.

[0024] A support assembly is provided on the rear side of one end of the fixed plate 2. The support assembly includes a fourth horizontal plate 13 fixedly connected to the rear side of one end of the fixed plate 2. A third horizontal plate 12 is fixedly connected to the upper side of the fourth horizontal plate 13 on the rear side of one end of the fixed plate 2. Multiple holes are opened at the top of the third horizontal plate 12 and the fourth horizontal plate 13. Limiting blocks are provided on the inner wall of the holes opened at the top of the fourth horizontal plate 13. An auxiliary assembly is provided at the rear end of the fixed plate 2. The auxiliary assembly includes an air outlet 14 fixedly connected to the rear end of the fixed plate 2. An air supply pipe 15 passes through the rear end of the air outlet 14. A fan 16 is fixedly connected to the other end of the air supply pipe 15. The bottom end of the fan 16 is fixedly connected to the top of the base 1. The air outlet 14 is used to blow air to the test tube opening at the bottom of the fourth horizontal plate 13.

[0025] Specifically, after cleaning, the test tube can be inverted between the third horizontal plate 12 and the fourth horizontal plate 13, so that the residual liquid on the inner wall of the test tube moves towards the mouth of the test tube under the action of gravity and falls into the collection tank 5. At the same time, the fan 16 can deliver air through the air supply pipe 15 to blow out from the air outlet 14, blowing the mouth of the inverted test tube, accelerating the gas flow rate at the mouth of the tube, thereby reducing the pressure at the mouth of the tube, accelerating the gas exchange rate between the inside of the tube and the outside, thereby accelerating the discharge of the residual liquid from the test tube and improving the drying efficiency of the test tube.

[0026] Working principle: During use, the operator inserts the test tube into the second horizontal plate 10, so that the bottom of the test tube contacts the support seat 9 on the first horizontal plate 8. With the help of the limiting ring 17 inside the second horizontal plate 10, the test tube remains vertical, allowing the chemical reagent inside to react. During this process, the operator can attach the shield 11 to the limiting ring 17 corresponding to the test tube, thus shielding the test tube opening. If a violent reaction occurs inside the test tube, any overflowing reagent or foam will be blocked by the shield 11, preventing it from accumulating on the second horizontal plate 10 and affecting the detection of reagents in adjacent test tubes. The reagent blocked by the shield 11 will flow downwards along the test tube wall and then through the first horizontal plate 8. The reagents drip into the collection tank 5 through the holes on plate 8. At this time, the small water pump 4 on the water inlet pipe 3 can be turned on to introduce clean water into the collection tank 5, so that the reagent mixed with clean water can be discharged from the drain pipe 7 more quickly. After the test is completed, the test tube can be inserted upside down into the third horizontal plate 12, so that the mouth of the test tube is stuck on the limiting block in the hole at the top of the fourth horizontal plate 13. At this time, the residual water inside the test tube will slide down under the action of gravity. During this process, the fan 16 can be turned on to draw in the outside air, which is sent to the air outlet 14 through the air supply pipe 15 to form wind force, which blows at the mouth of the test tube. According to Bernoulli's principle, the gas flow rate at the mouth of the test tube is accelerated, so that the pressure inside the test tube is greater than that at the mouth of the test tube, which accelerates the air inside the test tube to flow out and thus accelerates the discharge of residual water.

[0027] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
