Description

Technical Field

[0001] This utility model relates to the field of sample cup technology, specifically to a metal-capped sample cup. Background Technology

[0002] Sample cups are containers used for storing, transporting, or handling samples. They are widely used in fields such as chemistry, biology, environmental monitoring, and medicine. Sample cups play a crucial role in many experiments and routine tests, and ensuring the stability and validity of samples is one of the keys to experimental success.

[0003] The prior art has the following defects or problems: The prior art disclosed in publication number CN201637600U is a convenient sample cup, which has a cup body and a cup lid that is snapped onto the cup body. The bottom of the cup lid is integrally connected to a sampling spoon that extends into the cup body. The outer wall of the cup body has an elongated groove that is stably fitted into an elongated protrusion that is placed on the upper sample holder of the sample cup.

[0004] The above-mentioned equipment, based on the sampling cup device of this structure, uses a sampling spoon to take samples and place them into the cup. It is simple and convenient, can maintain the original properties of feces for a long time without deterioration, effectively improves the quality of fecal testing, saves time and effort, and utilizes the groove opened in the cup body to stably fit with the convex groove of the sample holder on which the sample cup is placed, improving stability and making it highly practical.

[0005] In the use of the cups described above, the lid is no different from that of traditional sample cups. It does not provide more comprehensive protection for the samples inside the cup, cannot ensure that the samples will not be affected by chemical reactions when stored in the cup for a long time, and cannot guarantee that the cup is completely sealed. This makes the samples inside easily damaged by the external environment.

[0006] Therefore, a metal-capped sample cup is proposed to solve the problems mentioned above. Utility Model Content

[0007] To address the shortcomings of existing technologies, this utility model provides a metal-capped sample cup, which can solve the problems of not providing more comprehensive protection for the sample inside the cup, not being able to ensure that the sample will not be affected by chemical reactions when stored in the cup for a long time, and not being able to guarantee that the cup is completely sealed, making the sample inside easily damaged by the external environment.

[0008] To achieve the above objectives, this utility model provides the following technical solution: It includes a cup body, with a cup mouth ring fixedly connected to the top of the cup body. At least two first limiting blocks are fixedly connected to the outer surface of the cup mouth ring, each of the at least two first limiting blocks having a first limiting opening inside. At least two first locking blocks are fixedly connected to the outer surface of the cup mouth ring. A metal cap is provided at the top of the cup mouth ring, with at least two second locking blocks fixedly connected to the outer surface of the metal cap. Each of the at least two second locking blocks is locked inside the first limiting opening, and the interior of the second limiting opening is locked to the first locking block.

[0009] Preferably, the metal cover has symmetrically formed inner grooves inside, a damper is fixedly connected inside the inner groove, a connecting rod is fixedly connected to the output end of the damper, a support plate is fixedly connected to the top end of the connecting rod, and connecting plates are fixedly connected to opposite sides of the support plates.

[0010] Preferably, a limiting groove is formed inside the connecting plate, a limiting ring is rotatably connected inside the limiting groove, and a connecting ring is fixedly connected inside the limiting ring.

[0011] Preferably, a fixing rod is fixedly connected inside the connecting ring, and a rubber sealing block is fixedly connected to the bottom end of the fixing rod.

[0012] Preferably, the inside of the cup ring has a sealing opening, and the inside of the sealing opening is threadedly connected to the rubber sealing block.

[0013] Preferably, a rotating block is fixedly connected to the top end of the fixing rod, and the fixing rod is inserted inside the connecting plate.

[0014] Preferably, the outer surface of the connecting ring is rotatably connected to the inside of the connecting disc.

[0015] Compared with the prior art, the present invention provides a metal-capped sample cup, which has the following advantages: 1. By incorporating a metal lid, the sample inside the cup is adequately protected, ensuring that the sample will not be affected by chemical reactions during long-term storage. Furthermore, the connection between the lid and the cup is simple, saving the need for multiple rotations and improving convenience.

[0016] 2. By setting a rubber sealing block inside the metal cover, the protection of the internal sample is enhanced, allowing the sample to be stored in a completely sealed environment, extending the sample storage time, and facilitating its widespread use. Attached Figure Description

[0019] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0020] 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.

[0021] Example: Please see Figure 1 - Figure 4 The metal-capped sample cup in this embodiment includes a cup body 1. A cup mouth ring 2 is fixedly connected to the top of the cup body 1. At least two first limiting blocks 3 are fixedly connected to the outer surface of the cup mouth ring 2. A first limiting opening 4 is opened inside the at least two first limiting blocks 3. At least two first locking blocks 5 are fixedly connected to the outer surface of the cup mouth ring 2. The top of the cup ring 2 is provided with a metal cover 6. At least two second locking blocks 7 are fixedly connected to the outer surface of the metal cover 6. At least two second locking blocks 7 are locked inside the first limiting port 4. At least two second limiting blocks 8 are fixedly connected to the outer surface of the metal cover 6. At least two second limiting ports 9 are opened inside the at least two second limiting blocks 8. The inside of the second limiting ports 9 is locked to the first locking block 5.

[0022] In this process, after the sample is placed inside the cup body 1, the metal cap 6 is manually removed and snapped onto the top of the cup mouth ring 2. Then, the metal cap 6 is rotated so that the second limiting block 8 rotates on the outer surface of the cup mouth ring 2, snapping the first locking block 5 into the inside of the second limiting port 9, and snapping the second locking block 7 into the inside of the first limiting port 4. This makes the metal cap 6 and the cup mouth ring 2 fit tightly together. The cooperation between the first limiting block 3 and the first limiting port 4 makes the second locking block 7 snap into the inside of the first limiting port 4.

[0023] The metal cover 6 has symmetrically arranged inner grooves 10 inside. A damper 11 is fixedly connected inside the inner groove 10. A connecting rod 12 is fixedly connected to the output end of the damper 11. A support plate 13 is fixedly connected to the top of the connecting rod 12. A connecting plate 14 is fixedly connected to the opposite side of the support plate 13. A limit groove 15 is opened inside the connecting plate 14. A limit ring 16 is rotatably connected inside the limit groove 15. A connecting ring 17 is fixedly connected inside the limit ring 16. A fixing rod 18 is fixedly connected inside the connecting ring 17. A rubber sealing block 19 is fixedly connected to the bottom end of the fixing rod 18. A sealing port 20 is opened inside the cup ring 2. The inside of the sealing port 20 is threadedly connected to the rubber sealing block 19. A rotating block 21 is fixedly connected to the top of the fixing rod 18. The fixing rod 18 is inserted into the inside of the connecting plate 14, and the outer surface of the connecting ring 17 is rotatably connected to the inside of the connecting plate 14.

[0024] The rotating block 21 drives the connecting plate 14 and the support plate 13 to move downwards. The support plate 13 pushes the connecting rod 12, and the damper 11 inside the inner groove 10 generates a damping effect. The rotating block 21 drives the connecting ring 17 to push the fixing rod 18 and the rubber sealing block 19 into the sealing port 20. Then, the rotating block 21 is rotated, which drives the connecting ring 17 and the limiting ring 16 to rotate inside the limiting groove 15. The limiting ring 16 provides a certain limiting effect on the connecting ring 17, maintaining the stability of the connecting ring 17. At the same time, the connecting ring 17 drives the fixing rod 18 and the rubber sealing block 19 to rotate inside the sealing port 20, fixing them in the sealing port 20 in the form of threads.

[0025] The working principle of the above embodiment is as follows: In the overall structure, the damper 11 is an existing mechanism of model TS93. During use, it is locked by pressing and rebounded by pressing again, so that the output end can be extended for quick fixation according to the length of the connecting rod 12. The limiting ring 16 rotates in the limiting groove 15, which has a certain limiting effect on the connecting ring 17, maintains the stability of the connecting ring 17, and prevents the connecting ring 17 from shifting inside. Through the threaded cooperation between the rubber sealing block 19 and the sealing port 20, a sealed space is formed inside the cup body 1, which can extend the survival time of the sample inside.

[0026] The installation, connection, or setting methods disclosed in this embodiment are all common mechanical connection methods. As long as they can achieve their beneficial effects, they can be implemented. Therefore, this embodiment will not elaborate on their specific structural composition and working principle.

[0027] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
