Among these steps, post-collection processing and storage of samples are crucial for ensuring the accuracy and reliability of test results.

[0003] Currently, samples are typically stored in storage tubes. Conventional storage tubes are usually made of glass or plastic and are typically simple, straight, sealed tubes with caps for sealing.

[0004] However, in actual use, the caps of conventional sample storage tubes are usually simple screw caps or plug caps. When subjected to frequent opening and closing, vibration during transportation, or changes in ambient temperature and pressure, such structures are prone to sealing failure, which can lead to sample leakage and affect the reliability of sample storage and the accuracy of subsequent testing. Utility Model Content

[0005] This utility model provides an environmental monitoring sample storage tube. Through the cooperation of a threaded ring, a threaded groove, and a sealing plug, it can provide a stable seal at the connection between the tube cap and the tube neck. The setting of the slot and the compression ring can cause the sealing ring to deform and fit tightly against the surface of the sealing plug, achieving a double sealing effect and preventing sample leakage. This solves the problem mentioned in the background art that the traditional sample storage tube has poor sealing performance, which leads to easy sample leakage and affects its storage reliability and detection accuracy.

[0028] Example:

[0029] Reference Figures 1-4An environmental monitoring sample storage tube includes a tube body 1 and a neck 2 fixedly connected to the tube body 1. A cap 3 is provided on the neck 2. The tube also includes a sealing plug 4 rotatably connected to the bottom end of the cap 3. The cap 3 is detachably installed on the neck 2. A threaded ring 8 is fixedly connected to the bottom end of the cap 3. A threaded groove 9 is formed at the top of the neck 2, and the threaded ring 8 is threaded into the threaded groove 9. When the cap 3 is connected to the neck 2, the sealing plug 4 is inserted into the neck 2 and tightly adheres to its inner wall. The upper half of the sealing plug 4 is cylindrical, and the lower half is frustum-shaped. This design serves as a guide, facilitating the insertion of the sealing plug 4 into the neck 2. The diameter of the upper half of the sealing plug 4 is slightly larger than the inner diameter of the neck 2, ensuring a tight seal. 4. An interference fit between the tube neck 2 and the tube cap 3; a sealing ring 5 is set inside the tube neck 2, and a groove 51 is opened inside the tube neck 2. The sealing ring 5 is fixedly connected inside the groove 51. An extrusion member is set at the bottom of the tube cap 3. The extrusion member is used to deform the sealing ring 5 and make it fit tightly against the surface of the sealing plug 4. The sealing ring 5 and the sealing plug 4 are both made of rubber or silicone. The above materials have good plasticity and elasticity and can play a good sealing role. The extrusion member includes an extrusion ring 7, which is fixedly connected to the bottom end of the tube cap 3. A slot 6 is opened on the sealing ring 5. When the tube cap 3 is connected to the tube neck 2, the extrusion ring 7 is inserted into the slot 6. The cross-sectional shape of the extrusion ring 7 is conical so that it can be inserted into the slot 6, so that the sealing ring 5 gradually expands.

[0030] Specifically, in use, first connect the tube cap 3 to the tube neck 2, allowing the sealing plug 4 to be inserted into the tube neck 2 and pressed against its inner wall. Then, by rotating the tube cap 3, the threaded ring 8 is threaded into the threaded groove 9, allowing the sealing plug 4 to be inserted more tightly, providing a stable seal at the connection between the tube cap 3 and the tube neck 2, thus effectively preventing sample leakage from the tube body 1. During installation, the compression ring 7 is inserted into the slot 6 and gradually increases the compression on its inner wall, causing the sealing ring 5 to deform and gradually expand. At this time, the contact pressure between the sealing ring 5 and the inner wall of the slot 51 and the outer wall surface of the sealing plug 4 increases dramatically, and they fit tightly together, achieving a double sealing effect. This greatly improves the sealing reliability of the sample storage tube, avoids sealing failure due to external forces, eliminates sample leakage, and thus ensures the reliability of sample storage and the accuracy of subsequent testing.

[0031] Of course, in other embodiments, the tube cap 3 is provided with a plurality of anti-slip strips 10, and the plurality of anti-slip strips 10 are arranged at equal intervals on the circumferential surface of the tube cap 3. The number of anti-slip strips 10 is 40-100, and the sample storage tube is preferably 80. A label area 11 is provided on the outer wall of the tube body 1.

[0032] Specifically, the anti-slip strip 10 can be used to increase the friction of the tube cap 3 surface, making it easier for users to apply force to rotate it. The label area 11 can be used to attach information sticky notes related to the sample, so that users can manage the sample tube in a variety of ways.
