Description

A disposable flip-top sampling tube Technical Field

[0001] This utility model relates to the field of sampling tube technology, and in particular to a disposable flip-top sampling tube. Background Technology

[0002] A sampling tube is a tube used to collect collected samples, allowing for proper classification and collection of the samples for subsequent testing.

[0003] For example, a disposable flip-top sampling tube with publication number "CN220767002U" solves the problem that existing disposable flip-top sampling tubes cannot store two different samples that need to be collected simultaneously. It allows for the appropriate collection and storage of different types of samples through a first sampling tube and a second sampling tube. The second sampling tube can be slid into and locked with the first sampling tube for simultaneous storage, facilitating separation and classification. However, existing disposable flip-top sampling tubes reduce the user experience. In addition, the process of opening the cap at the top of the sampling tube requires pulling the cap off the sampling tube, which requires storing the cap. If the lower part of the cap is contaminated, it will affect the quality of the inside of the sampling tube. Summary of the Invention

[0004] This invention aims to solve the problems existing in the prior art by providing a disposable flip-top sampling tube that eliminates the need for storing the cap, reduces contamination at the bottom of the cap, and improves the quality of the sample inside the tube.

[0005] The technical solution adopted by this utility model to solve its technical problem is as follows:

[0006] Design a disposable flip-top sampling tube, including a sampling tube and a circular groove. The inner wall of the sampling tube is machined with a circular groove, and the outer wall of the sampling tube is machined with anti-slip texture. The inner wall of the circular groove abuts against a silicone ring, and the outer wall of the silicone ring is fixedly connected to the circular ring. The outer wall of the circular ring is connected to an installation mechanism.

[0007] Further improvements include the installation mechanism comprising an installation ring, the lower end of which is fixedly connected to a circular ring, the inner wall of which is machined with a groove, and the outer wall of which is rotatably connected to a circular sleeve.

[0008] Further improvements include a fixed connection between the outer wall of the circular sleeve and the plastic strip, with a sealing mechanism connected to the end of the plastic strip.

[0009] Further improvements include a cover, the outer wall of which is fixedly connected to a plastic strip, the lower edge of which is fixedly connected to a locking block, and the lower end of which is fixedly connected to a sealing plug.

[0010] Further improvements include a fixed connection between the outer wall of the cover and the protrusion.

[0011] Further improvements include a fixed connection between the outer wall of the sampling tube and the label.

[0012] The beneficial effects of this utility model are as follows: By pushing the protrusion left and right with the thumb, the cover and plastic strip are rotated. The locking block at the bottom of the cover slides into the slot to the maximum and minimum ends. The locking block will disengage from or lock into the slot, opening and closing the cover with the mounting ring at the top of the sampling tube. The sealing plug at the bottom of the cover will enter the mounting ring and be pulled out or detached. This eliminates the need to store the cover, reduces contamination at the bottom of the cover, and improves the quality inside the sampling tube. Attached Figure Description

[0021] The present invention will be further described below with reference to the accompanying drawings:

[0022] Example 1:

[0023] Referring to Figures 1-7: In this embodiment, a disposable flip-top sampling tube includes a sampling tube 1 and a circular groove 2. The inner wall of the sampling tube 1 is machined with a circular groove 2, and the outer wall of the sampling tube 1 is machined with anti-slip texture 3. The inner wall of the circular groove 2 abuts against a silicone ring 4, and the outer wall of the silicone ring 4 is fixedly connected to a circular ring 5. An installation mechanism 6 is connected to the outer wall of the circular ring 5.

[0024] The mounting mechanism 6 includes a mounting ring 601, which is fitted onto the mounting ring 601 by a sleeve 603 to achieve the mounting effect between the cover 801 and the mounting ring 601. The lower end of the mounting ring 601 is fixedly connected to the ring 5. The inner wall of the mounting ring 601 is machined with a groove 602, and the outer wall of the mounting ring 601 is rotatably connected to the sleeve 603.

[0025] Pushing the protrusion 9 left and right with your thumb causes the cover 801 and plastic strip 7 to rotate. The locking block 802 at the lower end of the cover 801 slides into the slot 602 to its maximum and minimum positions. The locking block 802 will disengage from or lock into the slot 602, opening and closing the cover 801 with the mounting ring 601 at the upper end of the sampling tube 1. The sealing plug 803 at the lower end of the cover 801 will enter the mounting ring 601 and be pulled out or detached. This eliminates the need to store the cover, reduces contamination at the lower end of the cover, and improves the quality of the contents inside the sampling tube.

[0026] The outer wall of the round sleeve 603 is fixedly connected to the plastic strip 7. The end of the plastic strip 7 is connected to a sealing mechanism 8, which is clamped from the slot 602 by the locking block 802 to achieve sealing of the opening between the sealing plug 803 at the lower end of the cover 801 and the mounting ring 601. The sealing mechanism 8 includes the cover 801, the outer wall of the cover 801 is fixedly connected to the plastic strip 7, the edge at the lower end of the cover 801 is fixedly connected to the locking block 802, and the lower end of the cover 801 is fixedly connected to the sealing plug 803.

[0027] The outer wall of the cover 801 is fixedly connected to the protrusion 9, and the outer wall of the sampling tube 1 is fixedly connected to the label 10.

[0028] Working principle:

[0029] The sampling tube 1 is inserted into the circular ring 5, and the outer wall of the circular ring 5 and the silicone ring 4 are pressed tightly against the circular groove 2, thus sealing the sampling tube 1 and the circular ring 5. Simultaneously, the protrusion 9 is pushed, causing the cover 801 and the plastic strip 7 to rotate, and the circular sleeve 603 on the plastic strip 7 rotates on the mounting ring 601. This causes the locking block 802 at the lower end of the cover 801 to slide into the groove 602 to its minimum position, locking the lower end of the locking block 802 into the groove 602. The sealing plug 803 at the lower end of the cover 801 then enters the mounting ring 601, achieving a seal on the mounting ring 601. Similarly, the upper end of the sampling tube 1 also needs to be sealed. When the end is opened, the reverse push of the protrusion 9 causes the cover 801 and plastic strip 7 to rotate, and the circular sleeve 603 on the plastic strip 7 rotates on the mounting ring 601. After the locking block 802 at the lower end of the cover 801 slides into the slot 602 to the maximum end, the locking block 802 will disengage from the slot 602. When the plastic strip 7 applies upward pressure with the circular sleeve 603 as the fulcrum, the cover 801 at the upper end of the plastic strip 7 will automatically pop open, and the sealing plug 803 at the lower end of the cover 801 will enter the mounting ring 601 and be pulled out, so that the upper end of the sampling tube 1 is in an open state, which can be used to collect liquid.
