Description

Technical Field

[0001] This utility model relates to the field of plastic test tube technology, specifically a high-sealing plastic test tube. Background Technology

[0002] Plastic test tubes are test tubes made of plastic materials, typically used in laboratories to process small amounts of liquids. The main materials of plastic test tubes include polypropylene and polyethylene, and they are cylindrical in shape, closed at one end and open at the other. They are commonly used for storing and transporting liquids such as medicines and chemical reagents. Disposable plastic test tubes are also used as reaction containers for small amounts of reagents, for collecting small amounts of gas, and for assembling small gas generators. The characteristics of plastic test tubes include high transparency, light weight, environmental friendliness, and odorlessness, and they meet export quality standards. To improve the efficiency of liquid processing in laboratories, a new type of plastic test tube is needed. However, existing plastic test tubes still have the following shortcomings:

[0003] When using existing plastic test tubes, most plastic test tubes rely on a single structure to prevent liquid leakage. This means that different usage environments can easily affect the normal use of the test tubes, leading to liquid contamination or chemical reactions with other liquids. As a result, the practicality of plastic test tubes decreases and their usage efficiency is reduced.

[0004] Therefore, in view of this, we studied and improved the existing structure and its shortcomings, and proposed a high-sealing plastic test tube. Utility Model Content

[0005] The purpose of this invention is to provide a high-sealing plastic test tube to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a high-sealing plastic test tube, comprising a main body, an anti-slip top cover, and a rubber sealing ring. An installation ring is provided at the upper outer end of the main body, and an anti-loss connecting rope is connected to the outside of the installation ring. An anti-slip top cover is installed at the front end of the anti-loss connecting rope. An installation docking block is provided at the lower middle part of the anti-slip top cover. A rubber sealing ring is added to the outer middle part of the installation docking block. A sealing docking groove is opened at the upper inner end of the main body, and a lower installation groove is opened inside the upper inner end of the main body, with a sealing ring connected inside the lower installation groove. An upper installation groove is opened at the lower inner end of the anti-slip top cover. A polyurethane layer is provided inside the main body.

[0007] Furthermore, the internal dimensions of the mounting ring are adapted to the external dimensions of the main body, and the mounting ring is fixedly connected to the main body.

[0008] Furthermore, the outer side of the anti-slip top cover is horizontally distributed with the outer side of the main body, and the anti-slip top cover is connected to the main body via an anti-loss connecting rope.

[0009] Furthermore, the outer side of the anti-slip top cover and the outer side of the mounting docking block are horizontally distributed, and the mounting docking block is fixedly connected to the anti-slip top cover.

[0010] Furthermore, the external dimensions of the mounting docking block are adapted to the internal dimensions of the main body, and the mounting docking block and the main body are embedded in each other.

[0011] Furthermore, the external dimensions of the rubber sealing ring are adapted to the internal dimensions of the sealing groove, and the rubber sealing ring is connected to the main body through the sealing groove.

[0012] Furthermore, the internal dimensions of the lower mounting groove are adapted to the external dimensions of the sealing ring, and the sealing ring is connected to the main body through the lower mounting groove.

[0013] Furthermore, the sealing ring is embedded in the upper mounting groove, and the sealing ring is connected to the anti-slip top cover through the upper mounting groove.

[0014] This invention provides a highly airtight plastic test tube, which has the following advantages:

[0015] 1. This utility model, through the setting of a rubber sealing ring, enables the installation docking block to be fixedly installed in the middle of the lower end of the anti-slip top cover when using a high-sealing plastic test tube. The rubber sealing ring is also fixedly installed in the middle of the outer side of the installation docking block using adhesive. After the installation docking block is installed inside the main tube, the rubber sealing ring and the sealing docking groove are tightly connected. This improves the sealing performance of the installation docking block after use, preventing liquid leakage inside the plastic test tube and further increasing the overall practicality and efficiency of the plastic test tube.

[0016] 2. This utility model, through the addition of a polyurethane layer, enables the sealing ring to be installed on the upper end of the main tube via a lower mounting groove inside the main tube when using a high-sealing plastic test tube. The upper mounting groove, in conjunction with the lower mounting groove, limits the sealing ring, further enhancing the sealing performance after the anti-slip top cover is connected to the main tube. This improves the overall efficiency of the plastic test tube. Furthermore, the polyurethane layer added inside the main tube possesses acid and alkali resistance, corrosion resistance, and high-temperature resistance, thereby improving the high-temperature resistance and other performance characteristics of the plastic test tube, enhancing its overall practicality and efficiency.

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] like Figures 1 to 3 As shown, a high-sealing plastic test tube includes a main body 1, an anti-slip top cover 4, and a rubber sealing ring 6. An installation ring 2 is provided at the upper outer end of the main body 1, and an anti-loss connecting rope 3 is connected to the outside of the installation ring 2. The anti-slip top cover 4 is installed at the front end of the anti-loss connecting rope 3. An installation docking block 5 is provided at the lower middle of the anti-slip top cover 4, and a rubber sealing ring 6 is added to the middle of the outer side of the installation docking block 5. A sealing docking groove 7 is opened at the upper inner end of the main body 1. The internal dimensions of the installation ring 2 are adapted to the external dimensions of the main body 1, and the installation ring 2 is fixedly connected to the main body 1. The outer side of the anti-slip top cover 4 is horizontally distributed with the outer side of the main body 1, and the anti-slip top cover 4 is connected to the main body 1 via the anti-loss connecting rope 3. The outer side of the anti-slip top cover 4 is horizontally distributed with the outer side of the installation docking block 5, and the installation docking block 5 is fixedly connected to the anti-slip top cover 4. The external dimensions of the installation docking block 5 are similar to those of the main body 1. The internal dimensions of the main body 1 are compatible, and the mounting docking block 5 is embeddedly connected to the main body 1. The external dimensions of the rubber sealing ring 6 are compatible with the internal dimensions of the sealing docking groove 7, and the rubber sealing ring 6 is connected to the main body 1 through the sealing docking groove 7. The mounting docking block 5 is fixedly installed in the middle of the lower end of the anti-slip top cover 4 with adhesive, and the rubber sealing ring 6 is fixedly installed in the middle of the outer end of the mounting docking block 5 with adhesive. The external dimensions of the rubber sealing ring 6 are compatible with the internal dimensions of the sealing docking groove 7 opened at the upper end of the main body 1. At the same time, after the mounting docking block 5 is installed into the main body 1, the rubber sealing ring 6 and the sealing docking groove 7 are tightly connected. Thus, the rubber sealing ring 6 and the sealing docking groove 7 improve the sealing performance of the mounting docking block 5 after use, thereby preventing liquid from leaking inside the plastic test tube and further increasing the overall practicality and efficiency of the plastic test tube.

[0023] like Figures 1 to 3As shown, a lower mounting groove 8 is provided inside the upper end of the main pipe body 1, and a sealing ring 9 is connected inside the lower mounting groove 8. An upper mounting groove 10 is provided inside the lower end of the anti-slip top cover 4. A polyurethane layer 11 is provided inside the main pipe body 1. The internal dimensions of the lower mounting groove 8 are adapted to the external dimensions of the sealing ring 9, and the sealing ring 9 is connected to the main pipe body 1 through the lower mounting groove 8. The sealing ring 9 and the upper mounting groove 10 are embedded in each other, and the sealing ring 9 is connected to the anti-slip top cover 4 through the upper mounting groove 10. The sealing ring 9 is installed on the main pipe body 1 through the lower mounting groove 8 provided inside the upper end of the main pipe body 1. At the same time, the external dimensions of the sealing ring 9 are adapted to the internal dimensions of the upper mounting groove 10 opened at the lower end of the anti-slip top cover 4. Thus, the upper mounting groove 8 cooperates with the lower mounting groove 10 to limit the sealing ring 9, and the sealing ring 9 is used to further improve the sealing performance after the anti-slip top cover 4 and the main body 1 are connected and installed, thereby improving the overall efficiency of the plastic test tube. Meanwhile, the polyurethane layer 11 added inside the main body 1 has the properties of acid and alkali resistance, corrosion resistance and high temperature resistance, thereby improving the high temperature resistance and other performance of the plastic test tube, and improving the overall practicality and efficiency of the plastic test tube.

[0024] In summary, when using this high-sealing plastic test tube, the mounting ring 2 is first fixed to the upper part of the main tube body 1 with adhesive. Simultaneously, the anti-loss connecting rope 3 is fixed to the outside of the mounting ring 2 using heat fusion, and the front end of the anti-loss connecting rope 3 is connected to the anti-slip top cover 4 via heat fusion, thus preventing the anti-slip top cover 4 from being lost. The mounting docking block 5 is then fixed to the lower middle part of the anti-slip top cover 4 with adhesive, and the rubber sealing ring 6 is fixed to the outer middle of the mounting docking block 5 with adhesive. After the mounting docking block 5 is installed inside the main tube body 1, the rubber sealing ring 6 is tightly connected to the sealing docking groove 7, thereby ensuring the high-sealing performance of the test tube. The sealing ring 6, in conjunction with the sealing groove 7, enhances the sealing performance of the installation and connection block 5 after use. Then, the sealing ring 9 is installed on the upper end of the main body 1 through the lower installation groove 8 opened inside the main body 1. At the same time, the upper installation groove 8, in conjunction with the lower installation groove 10, limits the sealing ring 9 and further enhances the sealing performance of the anti-slip top cover 4 after it is installed with the main body 1, thereby improving the overall efficiency of the plastic test tube. Meanwhile, the polyurethane layer 11 added inside the main body 1 has the properties of acid and alkali resistance, corrosion resistance, and high temperature resistance, thereby improving the high temperature resistance and other performance characteristics of the plastic test tube, and improving the overall practicality and efficiency of the plastic test tube.
