Description

Technical Field

[0001] The present application relates to the field of reagent tubes, and in particular to an anti-pollution reagent tube. Background Art

[0002] Reagent tubes are commonly used instruments in chemical laboratories. They are used as reaction containers for small amounts of reagents and are used at room temperature or when heated. When testing personnel are sampling patients' bodies, the collected samples are usually placed in reagent tubes for temporary storage.

[0003] Among the existing Chinese utility models, the publication number CN215783468U discloses an anti-pollution test tube for the laboratory. The test tube includes a test tube, the bottom end of which is fixedly connected with a bottom rubber ring, the bottom rubber ring and the upper rubber ring are arranged because the diameter is larger than the test tube, the thickness of the bottom rubber ring is greater than the upper rubber ring, and the bottom rubber ring is heavier. When the test tube falls, the bottom rubber ring will first contact the ground. The setting of the arc portion makes the bottom rubber ring evenly stressed when it touches the ground. When the test tube is buffered, it will not bounce to one side due to uneven stress. Through the top cap, the inner side of the test tube can be pressurized. After the inner side of the test tube is pressurized by the top cap, positive pressure appears on the inner side of the test tube, which can prevent the intrusion of dust and the like during transportation.

[0004] When temporarily storing samples, in order to prevent the samples from being contaminated, a top cap is usually threaded on the top of the reagent tube to seal the reagent tube, such as the anti-contamination test tube mentioned above. However, when the test tube is opened, the top cap and the reagent tube are in a separated state. After sampling, the top cap needs to be screwed on separately to ensure that the reagent tube is sealed. If the top cap is not screwed on in time due to carelessness, the sample in the reagent tube may be contaminated, and even when the reagent tube is tipped over, the sample may spill and pollute the environment.

[0005] Therefore, it is hoped to provide an anti-contamination reagent tube that can be opened and closed, so that while it is convenient to take samples, there is no need to worry about the samples being contaminated and to avoid the staff being careless and causing the reagent tube to be unsealed, causing the samples to spill and pollute the environment.

A support frame 2 and a fixed block 3 are fixedly connected to the outer wall of the reagent tube 1. The fixed block 3 and the support frame 2 are respectively located at the top and bottom of the reagent tube 1. A sliding groove 1 8 and a sliding groove 2 9 are opened on the side wall of the fixed block 3. The fixed block 3 is provided with a sealing structure 4 and a pulling structure 5, and the pulling structure 5 is provided with a pressing structure 6. The outer side of the reagent tube 1 is provided with a snap-on structure 10.

[0032] The inner cavities of the sliding groove 1 8 and the sliding groove 2 9 are communicated with each other.

[0033] The sealing structure 4 includes a sealing plate 401, a sealing gasket 402, a snap-in groove 403 and a snap-in block 404. The sealing plate 401 is slidably connected in the sliding groove 29.

A snap-in block 404 is fixedly connected to the side wall on the other side of the sealing plate 401 and the sealing gasket 402. The snap-in block 404 and the snap-in groove 403 cooperate with each other. The snap-in block 404 on the sealing plate 401 can be snapped into the snap-in groove 403 on another sealing plate 401. The sealing gasket 402 makes the sealing plates 401 sealed and connected to each other.

[0034] The sealing pad 402 is made of rubber, which has a good sealing effect.

[0035] The pulling structure 5 includes a pull rope 501, a sliding sleeve 502, a fixed ring 503 and a spring 504. The spring 504 is fixedly connected between the sealing plate 401 and the sliding groove 29. One end of the pull rope 501 is fixedly connected to the side wall of the sealing plate 401. The other end of the pull rope 501 passes through the sliding groove 18 and is fixedly connected to the sliding sleeve 502. The sliding sleeve 502 is slidably connected to the outer wall of the reagent tube 1. Two fixed rings 503 are fixedly connected to the outer wall of the sliding sleeve 502. When the sliding sleeve 502 is pulled downward, the limit block 1001 slides in the limit groove 7 to limit the rotation of the sliding sleeve 502. The sliding sleeve 502 pulls the pull rope 501 to move, and the pull rope 501 drives the sealing plate 401 to move. The spring 504 is compressed, and the sealing plate 401 retracts into the sliding groove 29.

[0036] The side wall of the sliding sleeve 502 is provided with two limiting grooves 7, a second clamping groove 11 and a fourth sliding groove 12.

[0037] The inner cavities of the limiting groove 7, the second clamping groove 11 and the fourth sliding groove 12 are connected.

[0038] The clamping structure 10 includes a limit block 1001, a spring three 1002, a sliding groove three 1003 and a clamping block two 1004. The limit block 1001 is fixedly connected to the outer walls on the left and right sides of the reagent tube 1. The side wall of the limit block 1001 is provided with a sliding groove three 1003.

[0040] The pressing structure 6 includes a pressing block 601, a spring 602 and a pressing rod 603. The pressing rod 603 is slidably connected in the sliding groove 12. One end of the pressing rod 603 is fixedly connected to the arc-shaped pressing block 601. The spring 602 is fixedly connected between the pressing block 601 and the sliding sleeve 502. When the pressing block 601 is pinched inward, the pressing block 601 approaches the sliding sleeve 502, the spring 602 is compressed, and the pressing rod 603 moves inward to press the clamping block 1004.

[0041] When the utility model is in use, when placing the reagent tube 1, the support frame 2 is supported on the desktop, so that the reagent tube 1 can be better erected on the desktop. When opening the test tube, the finger can be inserted into the fixing ring 503, and the pressing block 601 is pinched inwardly. The pressing block 601 is close to the sliding sleeve 502, and the spring 602 is compressed, and the pressing rod 603 moves inward, pressing the clamping block 1004, and the clamping block 1004 retracts into the sliding groove 1003, and the sliding sleeve 502 is no longer restricted. 2. Pull the sliding sleeve 502 downward, the limit block 1001 slides in the limit groove 7, which can limit the rotation of the sliding sleeve 502. The sliding sleeve 502 pulls the pull rope 501 to move, and the pull rope 501 drives the blocking plate 401 to move. The spring 1 504 is compressed, and the blocking plate 401 retracts into the sliding groove 2 9, no longer blocking the top of the reagent tube 1, so that the top of the reagent tube 1 can be opened. The tester can inject the sample into the reagent tube 1 or take the sample from the reagent tube 1, and withdraw his hand from the fixing ring 503. The sliding sleeve 502 is no longer subjected to tension, and the spring 1 504 is expanded to push the blocking plate 401 to re-seal the top of the reagent tube 1. The clamping block 1 404 on the blocking plate 401 is clamped into the clamping groove 1 403 on another blocking plate 401. The sealing gasket 402 makes the blocking plates 401 sealed and connected to each other, and the top of the reagent tube 1 is re-sealed to prevent the sample in the reagent tube 1 from being contaminated by the outside. , the pressing block 601 is no longer pressed, the spring 2 602 expands and pushes the pressing rod 603 to retract into the sliding groove 4 12. As the sliding sleeve 502 rises, until the clamping groove 2 11 is facing the clamping block 2 1004, the spring 3 1002 expands and pushes the clamping block 2 1004 to clamp into the clamping groove 2 11 again, fixing the sliding sleeve 502 to prevent the sliding sleeve 502 from sliding easily, causing the sealing plate 401 to open, causing the sample to be contaminated.

[0042] The benefits of this application are:

[0043] 1. The present application has a reasonable structure. By pulling the sliding sleeve downward, the sealing plate can be retracted into the sliding groove 2 and no longer blocks the top of the reagent tube, so that the top of the reagent tube is opened. When the hand is pulled out of the fixed ring, the sliding sleeve is no longer subjected to tension, and the sealing plate bounces back and re-seals the top of the reagent tube, making it easy to open and close the reagent tube. While it is convenient to take samples, there is no need to worry about the samples being contaminated.

[0044] 2. The structure of the present application is reasonable. When the reagent tube is not in use, the reagent tube will automatically close by simply releasing the hand. The staff does not need to manually take out and close the reagent tube, which can prevent the staff from being careless for a moment, resulting in the reagent tube not being blocked, causing the sample to spill and pollute the environment.

[0045] 3. The present application has a reasonable structure. The second clamping block is clamped into the second clamping groove to fix the sliding sleeve, thereby preventing the sliding sleeve from sliding easily, causing the sealing plate to open and causing the sample to be contaminated.
