Description

Technical Field

[0001] This utility model relates to the field of culture tube technology, specifically a modular triple cell stimulation culture tube that can be quickly disassembled. Background Technology

[0002] Currently, in the field of cell culture technology, cell stimulation culture tubes are a commonly used experimental tool used to simulate the cell growth environment in vitro and to conduct various stimulation experiments on cells. Traditional cell stimulation culture tubes mostly adopt an integrated design, that is, the culture tube and the cap are fixedly connected and cannot be quickly disassembled. Although this design ensures the sealing of the culture tube to a certain extent, it has many inconveniences in actual use.

[0003] Traditional integrated cell stimulation culture tubes are complex and time-consuming to change culture conditions or clean, failing to meet the needs of rapid and efficient experiments. Secondly, the inability to quickly disassemble the culture tube and cap makes it difficult to observe cell growth or perform other necessary operations during the experiment. Furthermore, traditional cell stimulation culture tubes also have certain defects in terms of sealing, making them prone to air or liquid leakage, which affects the accuracy of experimental results.

[0004] Therefore, we propose a modular triple cell stimulation culture tube that can be quickly disassembled, which not only allows for quick installation of the cap on the top of the culture tube, but also makes disassembly very convenient. Utility Model Content

[0005] The purpose of this invention is to provide a modular triple cell stimulation culture tube that can be quickly disassembled, thus solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a modular triple cell stimulation culture tube that can be quickly disassembled, comprising a culture tube with an open top, a limiting groove on one side of the top of the culture tube, a positioning mechanism inside the limiting groove, a tube cap inserted into the top of the culture tube, an insert block fixedly installed in the middle of the tube cap, a slot in the middle of the insert block, the slot corresponding to the positioning mechanism, and a sealing component installed at the other end of the insert block.

[0007] Optionally, the positioning mechanism includes a limiting block slidably installed in the limiting groove, a wedge block fixedly installed at one end of the side wall of the limiting block, a piston hole communicating through the middle of one side of the limiting groove, a piston rod slidably installed in the piston hole, and a spring sleeved on the outer wall of the piston rod. One end of the piston rod is fixedly installed to the other side wall of the limiting block, and both sides of the spring are fixedly installed to the inner wall of the limiting groove and the side wall of the limiting block, respectively.

[0008] By adopting the above technical solution, the pipe cap can be locked.

[0009] Optionally, a handle is fixedly installed at the other end of the piston rod, and the cross-sectional area of ​​the handle is larger than the cross-sectional area inside the piston hole.

[0010] By adopting the above technical solution, the wedge block can be moved.

[0011] Optionally, the inner wall of the cap fits into the outer wall of the top of the culture tube, and the bottom outer side of the insertion block has an oblique opening, which corresponds to the inclined surface of the wedge block.

[0012] By adopting the above technical solution, the wedge block can be squeezed into the limiting groove.

[0013] Optionally, the sealing assembly includes a connecting rod fixedly installed at the middle of the other end of the insert, a sealing plug fixedly installed at the other end of the connecting rod, grooves formed on both sides of the sealing plug, and sealing rings fitted in the two sets of grooves.

[0014] By adopting the above technical solution, the culture tube can be sealed.

[0015] Optionally, the sealing plug is movably connected to the inner cavity of the culture tube, and both sets of sealing rings are in contact with the inner wall of the culture tube.

[0016] By adopting the above technical solution, the sealing plug can be movably connected to the inner lumen of the culture tube.

[0017] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0018] The technical solution of this application uses an insert block inside the cap to connect to the culture tube. At the same time, the inclined opening at the bottom of the insert block continuously squeezes the wedge block in the positioning mechanism. Since the wedge block is supported by a spring on the piston rod, as the bottom of the insert block continuously squeezes the wedge block, the wedge block will be housed into the limiting groove along the direction of the limiting block slider. When the wedge block and the slot in the middle of the insert block correspond to each other, the wedge block will be squeezed out by the supporting force of the spring, so that the wedge block is limited in the slot, positioning the cap. This ensures that the operator can quickly seal the culture tube after inserting the cap to the top of the culture tube, and the positioning mechanism locks the cap, effectively preventing the cap from opening under external force.

[0019] The sealing plug is movably connected to the inner cavity of the culture tube, and both sets of sealing rings fit against the inner wall of the culture tube. When the tube cap is inserted into the top of the culture tube, the sealing plug at the bottom of the connecting rod will be inserted into the inner wall of the culture tube first. Both sides of the sealing plug are equipped with sealing rings. As the sealing plug is continuously inserted into the inner cavity of the culture tube, the sealing rings will fit tightly against the inner wall of the culture tube, effectively ensuring the airtightness of the culture tube.

[0025] Please see Figure 1-3 This utility model provides a technical solution: a modular triple cell stimulation culture tube 1 that can be quickly disassembled, including a culture tube 1 with an open top. A limiting groove 2 is formed on one side of the top of the culture tube 1, and a positioning mechanism is located inside the limiting groove 2. A tube cap 11 is inserted and installed at the top of the culture tube 1. An insert block 12 is fixedly installed in the middle of the tube cap 11. A slot 13 is formed in the middle of the insert block 12, and the slot 13 corresponds to the positioning mechanism. A sealing component is installed at the other end of the insert block 12 for positioning. The mechanism includes a limiting block 21 that is slidably installed in the limiting groove 2, a wedge block 22 that is fixedly installed at one end of the side wall of the limiting block 21, a piston hole 23 that is opened in the middle of one side of the limiting groove 2, a piston rod 24 that is slidably installed in the piston hole 23, and a spring 25 that is sleeved on the outer wall of the piston rod 24. One end of the piston rod 24 is fixedly installed to the other side wall of the limiting block 21, and both sides of the spring 25 are fixedly installed to the inner wall of the limiting groove 2 and the side wall of the limiting block 21, respectively, which can lock the cap 11.

[0026] The cap 11 is inserted into the culture tube 1 via the insert block 12 inside. Simultaneously, the inclined opening 14 at the bottom of the insert block 12 continuously presses the wedge block 22 in the positioning mechanism. Since the wedge block 22 is supported by the spring 25 on the piston rod 24, as the bottom of the insert block 12 continuously presses against the wedge block 22, the wedge block 22 will be retracted into the limiting groove 2 along the direction of the slider of the limiting block 21. When the wedge block 22 and the slot 13 in the middle of the insert block 12 correspond to each other, the wedge block 22 will be squeezed out by the supporting force of the spring 25, so that the wedge block 22 is limited in the slot 13, positioning the cap 11. This ensures that after the operator inserts the cap 11 into the top of the culture tube 1, the culture tube 1 can be quickly sealed, and the cap 11 is locked by the positioning mechanism, effectively preventing the cap 11 from opening under external force.

[0027] In this technical solution, the sealing assembly includes a connecting rod 3 fixedly installed at the middle of the other end of the insert block 12, a sealing plug 31 fixedly installed at the other end of the connecting rod 3, grooves opened on both sides of the sealing plug 31, and sealing rings 32 sleeved in the two sets of grooves, which can seal the culture tube 1. The sealing plug 31 is movably connected to the inner cavity of the culture tube 1, and the two sets of sealing rings 32 are mutually fitted with the inner wall of the culture tube 1, so that the sealing plug 31 can be movably connected to the inner cavity of the culture tube 1.

[0028] When the cap 11 is inserted into the top of the culture tube 1, the sealing plug 31 at the bottom of the connecting rod 3 will be inserted into the inner wall of the culture tube 1 first. With sealing rings 32 installed on both sides of the sealing plug 31, as the sealing plug 31 is continuously inserted into the inner cavity of the culture tube 1, the sealing rings 32 will fit tightly against the inner wall of the culture tube 1, effectively ensuring the airtightness of the culture tube 1.

[0029] In this technical solution, the inner wall of the cap 11 fits into the outer wall of the top of the culture tube 1, and the bottom outer side of the insert 12 is provided with a bevel 14, which corresponds to the bevel of the wedge block 22, so that the wedge block 22 can be squeezed into the limiting groove 2.

[0030] When the bottom of the insert block 12 continuously presses against the wedge block 22, the inclined opening 14 at the bottom of the insert block 12 will continuously press against the inclined side of the wedge block 22, making it easier for the wedge block 22 to be pressed into the limiting groove 2.

[0031] In this technical solution, a handle 26 is fixedly installed at the other end of the piston rod 24. The cross-sectional area of ​​the handle 26 is larger than the cross-sectional area inside the piston hole 23, which can push the wedge block 22 to move.

[0032] When the operator needs to open the cap 11, he can first hold the handle 26 and push it outward to squeeze the wedge block 22 into the limiting groove 2, so that the wedge block 22 cannot lock the cap 11, making it easy to remove the cap 11 from the end of the culture tube 1.

[0033] In use, after the culture tube 1 contains the specified cells, the operator needs to seal the culture tube 1 and insert the cap 11 into the top of the culture tube 1, so that the insert block 12 inside the cap 11 is inserted into the culture tube 1. At the same time, the inclined opening 14 at the bottom of the insert block 12 will continuously squeeze the wedge block 22 in the positioning mechanism. Since the wedge block 22 is supported by the spring 25 on the piston rod 24, as the bottom of the insert block 12 continuously squeezes the wedge block 22, the wedge block 22 will be retracted into the limiting groove 2 along the direction of the slider of the limiting block 21. When the wedge block 22 and the slot 13 in the middle of the insert block 12 correspond to each other, the wedge block 22 will be squeezed out by the supporting force of the spring 25, so that the wedge block 22 is limited in the slot 13. The cap 11 is positioned to ensure that the operator can quickly seal the culture tube 1 after inserting the cap 11 into the top of the culture tube 1. The positioning mechanism locks the cap 11 in place, effectively preventing the cap 11 from opening under external force. At the same time, the sealing plug 31 is movably connected to the inner cavity of the culture tube 1, and both sets of sealing rings 32 are in close contact with the inner wall of the culture tube 1. When the cap 11 is inserted into the top of the culture tube 1, the sealing plug 31 at the bottom of the connecting rod 3 will be inserted into the inner wall of the culture tube 1 first. With sealing rings 32 installed on both sides of the sealing plug 31, as the sealing plug 31 is continuously inserted into the inner cavity of the culture tube 1, the sealing rings 32 will be tightly fitted to the inner wall of the culture tube 1, effectively ensuring the sealing of the culture tube 1.
