Abstract
Description
Technical Field
[0001] This utility model belongs to the field of water quality testing technology, and specifically relates to a water quality testing sample tube and an anti-tipping structure. Background Technology
[0002] Water sample tubes are small containers used to collect, preserve, and transport water samples for chemical, physical, or biological analysis. They are typically made of glass or plastic, and the choice of material must consider its inertness to different contaminants and whether it will affect the test results. In laboratory water sample testing, the sample tubes are first removed from the storage tank and then placed into the analyzer. This process involves testing multiple sets of sample tubes, requiring frequent tube changes. During these changes, the used tubes are temporarily placed on the worktable, where occasional collisions or accidental contact can cause them to tip over. Two possibilities arise when a sample tube tipps: either it rolls to the ground and breaks (if it's made of glass), or the vibration may loosen the seal, causing solution leakage. Therefore, a new structure is proposed to address these issues. Utility Model Content
[0003] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a water quality testing sample tube and an anti-tipping structure to solve the problems mentioned in the background technology.
[0004] This utility model is achieved through the following technical solution: a water quality testing sample tube and an anti-tipping structure, comprising: an anti-tipping component, wherein the anti-tipping component includes a placement tube for docking with a stabilizing component, and the top of the placement tube is provided with an insertion port for inserting the sample tube body;
[0005] The insertion port has four sets of positioning grooves on its outer side. The stabilizing component includes a knob for sealing the top of the sample tube body. A fixing plate is provided below the knob. Four sets of positioning rods for docking with the positioning grooves are provided at the four corners of the bottom of the fixing plate.
[0006] In a preferred embodiment, a base is provided below the placement tube, and an anti-slip pad is glued to the bottom of the base. A weight-increasing ring for lowering the center of gravity of the anti-tipping component is embedded in the inner side of the bottom of the base. The bottom of the anti-slip pad has anti-slip patterns, which are composed of several sets of square protrusions, thus greatly increasing the friction of the base. The weight-increasing ring is located above the base and together with the base, greatly lowers the center of gravity of the anti-tipping component, thereby significantly improving the anti-tipping performance of the sample tube body.
[0007] In a preferred embodiment, the radius of the insertion port matches the radius of the sample tube body, and the depth below the insertion port matches the height of the sample tube body.
[0008] In a preferred embodiment, the four sets of positioning slots are equidistantly distributed with the center of the insertion port as the base point, and the distance between the four sets of positioning slots is the same as the distance between the four sets of positioning rods.
[0009] In a preferred embodiment, the radius and height of the positioning rod match the radius and depth of the positioning groove. A magnetic button is embedded in the bottom of the positioning rod. The lower inner side of the positioning groove is made of iron. The four sets of positioning rods are connected to the four sets of positioning grooves and are fixed by the four sets of magnetic buttons. The sample tube body is suspended and installed inside the placement tube. The limiting effect of the four sets of positioning rods prevents the sample tube body from shaking inside the placement tube, thus greatly increasing the stability of the sample tube body.
[0010] In a preferred embodiment, the positioning rod and the fixing plate are an integral structure, the fixing plate is a disc-shaped structure, and the radius of the fixing plate is greater than the radius of the sample tube body.
[0011] In a preferred embodiment, a threaded tube is provided at the center of the bottom of the fixing plate, the threaded tube has threads on the outside, a sealing ring for sealing the top of the sample tube body is glued to the outside of the threaded tube, and a knob for rotating the threaded tube is provided on the top of the fixing plate.
[0012] In a preferred embodiment, the top of the sample tube body is provided with a screw interface, and the inner side of the screw interface is provided with an internal thread groove that matches the thread specification. The radius length of the threaded tube matches the radius length of the screw interface, and the height of the threaded tube matches the depth of the screw interface.
[0013] After adopting the above technical solution, the beneficial effects of this utility model are as follows: 1. By setting an anti-tipping component, which includes a placement tube and a stabilizing component, the stabilizing component includes a fixing plate and a threaded tube. The threaded tube below the fixing plate is threadedly connected to the screw interface at the top of the sample tube body, so that the top of the sample tube body is tightly pressed against the bottom of the sealing ring above the threaded tube, sealing the top of the sample tube body. Then, the sample tube body and the fixing plate are picked up, and the four sets of positioning rods below the fixing plate are inserted into the four sets of positioning grooves at the top of the placement tube, so that the magnetic button at the bottom of the positioning rod is attracted and fixed to the bottom of the positioning groove. At the same time, the bottom of the sample tube body passes through the insertion port and is placed inside the placement tube. Due to the positioning effect of the four sets of positioning rods and positioning grooves, the sample tube body is suspended inside the placement tube, thus significantly improving the protection effect of the sample tube body.
[0014] 2. By setting a base and a weight-increasing ring, the base has an anti-slip pad glued to the bottom with anti-slip texture. The anti-slip pad is in direct contact with the workbench surface, thus increasing the friction between the base and the workbench surface. A weight-increasing ring is embedded in the upper inner side of the base. The base and weight-increasing ring lower the overall center of gravity of the anti-tipping component. Therefore, compared with placing the sample tube body directly on the workbench, the anti-tipping component protects the sample tube body and greatly improves the anti-tipping performance of the sample tube body.

[0024] 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 one aspect of the present utility model, and not all aspects. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present utility model.
[0025] Please see Figures 1 to 5 A water quality testing sample tube and an anti-tipping structure, comprising: an anti-tipping component, the anti-tipping component including a placement tube 100 for docking with a stabilizing component 200, the top of the placement tube 100 having an insertion port 101 for inserting the sample tube body 300;
[0026] Four sets of positioning grooves 102 are provided on the outside of the insertion port 101. The stabilizing component 200 includes a knob 230 for sealing the top of the sample tube body 300. A fixing plate 210 is provided below the knob 230. Four sets of positioning rods 220 for docking with the positioning grooves 102 are provided at the four corners of the bottom of the fixing plate 210.
[0027] A base 110 is provided below the placement tube 100. An anti-slip pad 111 is glued to the bottom of the base 110. A weight-increasing ring 120 for lowering the center of gravity of the anti-tipping component is embedded in the inner side of the bottom of the base 110. The bottom of the anti-slip pad 111 has anti-slip texture, which is composed of several sets of square protrusions, thus greatly increasing the friction of the base 110. The weight-increasing ring 120 is located above the base 110 and together with the base 110, it greatly lowers the center of gravity of the anti-tipping component, thereby significantly improving the anti-tipping performance of the sample tube body 300.
[0028] The radius of the insertion port 101 matches the radius of the sample tube body 300, and the depth below the insertion port 101 matches the height of the sample tube body 300.
[0029] The four sets of positioning grooves 102 are equidistantly distributed with the center of the insertion port 101 as the base point, and the distance between the four sets of positioning grooves 102 is the same as the distance between the four sets of positioning rods 220.
[0030] The radius and height of the positioning rod 220 match the radius and depth of the positioning groove 102. A magnetic button is embedded in the bottom of the positioning rod 220. The lower inner side of the positioning groove 102 is made of iron. The four sets of positioning rods 220 are connected to the four sets of positioning grooves 102 and are fixed by the four sets of magnetic buttons. The sample tube body 300 is suspended and installed inside the placement tube 100. The limiting effect of the four sets of positioning rods 220 prevents the sample tube body 300 from shaking inside the placement tube 100, thus greatly increasing the stability of the sample tube body 300.
[0031] The positioning rod 220 and the fixing plate 210 are an integral structure. The fixing plate 210 is a disc-shaped structure, and the radius of the fixing plate 210 is greater than the radius of the sample tube body 300.
[0032] The fixing plate 210 has a threaded tube 240 at the bottom center, and the threaded tube 240 has threads on the outside. A sealing ring 241 for sealing the top of the sample tube body 300 is glued to the upper outside of the threaded tube 240. The fixing plate 210 has a knob 230 for rotating the threaded tube 240.
[0033] The sample tube body 300 has a screw interface 310 at the top. The screw interface 310 has an internal thread groove that matches the thread specification. The radius of the threaded tube 240 matches the radius of the screw interface 310, and the height of the threaded tube 240 matches the depth of the screw interface 310.
[0034] Example 1: Please refer to Figures 1 to 5 In actual use, the placement tube 100 and the base 110 are integrated as a whole. The placement tube 100, the base 110, and the stabilizing component 200 together form an anti-tipping component. First, the base 110 is placed on the workbench so that the bottom of the anti-slip pad 111 glued to the bottom of the base 110 contacts the surface of the workbench. The bottom of the anti-slip pad 111 has anti-slip texture, which is composed of several sets of square protrusions. This greatly increases the friction between the base 110 and the workbench. A weight-increasing ring 120 is embedded in the inner side of the upper part of the base 110. The weight-increasing ring 120 is made of stainless steel. The weight-increasing ring 120 can lower the center of gravity of the anti-tipping component. Therefore, the lower center of gravity can significantly increase the anti-tipping performance of the sample tube body 300.
[0035] The stabilizing component 200 works in conjunction with the sample tube body 300. The threaded tube 240 below the fixing plate 210 is inserted downward into the inner side of the screw interface 310 above the sample tube body 300. A water-separating membrane is glued to the outer side of the threaded tube 240 and the outer side of the sealing ring 241 above the threaded tube 240 to prevent water from coming into contact with the threaded tube 240 and the sealing ring 241, which would cause changes in the water composition and affect the test results. Rotating the knob 230 on the top of the fixing plate 210 causes the threaded tube 240 to be threadedly connected to the inner side of the screw interface 310. As the threaded tube 240 rotates and descends at the screw interface 310, the top of the sample tube body 300 and the bottom of the sealing ring 241 come into tight contact, thereby achieving a good sealing and leak-proof effect on the top of the sample tube body 300.
[0036] After installation, lift the sample tube body 300 and the stabilizing component 200, and insert the four sets of positioning rods 220 at the bottom of the fixing plate 210 downwards into the four sets of positioning slots 102 at the top of the placement tube 100. Magnetic buttons are embedded in the bottom of the positioning rods 220. When the positioning rods 220 are inserted downwards into the bottom of the positioning slots 102, the magnetic buttons are attracted and fixed to the bottom of the iron positioning slots 102. At the same time, the sample tube body 300 is inserted downwards into the placement tube 100 through the insertion port 101. Therefore, through the interlocking connection of the four sets of positioning rods 220 and the four sets of positioning slots 102, the sample tube body 300 can be placed inside the placement tube 100, and the sample tube body 300 is suspended below the insertion port 101, greatly increasing the safety and stability of the sample tube body 300. Compared with placing the sample tube body 300 directly on the worktable, this greatly improves the anti-tipping performance of the sample tube body 300.
[0037] Example 2: Please refer to Figures 1 to 5 In actual use, the placement tube 100 and the base 110 are provided as a set, and the number of stabilizing components 200 is the same as the number of sample tube bodies 300. The stabilizing components 200 replace the original top cover of the sample tube body 300 and are directly screwed onto the sample tube body 300. In actual use, the researcher first places the base 110 and the placement tube 100 on the workbench, close to the water quality analyzer and at a certain distance. When conducting water quality testing, the sample tube body 300 is directly taken out from the storage cabinet and inserted into the detection port of the water quality analyzer. It should be noted that the horizontal height of the bottom of the positioning rod 220 is greater than the horizontal height of the bottom of the screw interface 310. Therefore, when the stabilizing components 200 are installed on the top of the sample tube body 300, the four sets of positioning rods 220 will not obstruct the sample tube body 300 from being inserted into the detection port, that is, it will not affect the normal detection work of the sample tube body 300.
[0038] After a set of sample tube bodies 300 has been tested, the sample tube body 300 is removed from the testing port and inserted into the placement tube 100. The sample tube body 300 is then suspended inside the placement tube 100 by the interlocking connection between four sets of positioning rods 220 and the positioning groove 102, as well as magnetic fixation. Because the bottom of the base 110 is glued with an anti-slip pad 111, and a weight-increasing ring 120 is embedded above the base 110, the center of gravity of the anti-tipping component and the sample tube body 300 is significantly reduced, thus demonstrating… This design increases the anti-tipping performance of the sample tube body 300. After placement, another set of sample tube bodies 300 with the same specifications but different internal water quality is taken out and placed inside the detection port for testing. Then, the sample tube body 300 inside the placement tube 100 is taken out and placed back in the marked area inside the storage cabinet to distinguish it from the sample tube body 300 that has not been tested. This process is repeated, which greatly increases the stability of the sample tube body 300 during replacement and prevents the sample tube body 300 from tipping over and breaking or leaking liquid during replacement.
[0039] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. 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.
