[0020] The embodiments of the present invention are described in detail below. Examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, but should not be construed as limiting the present invention.

Figure 3 This is a cross-sectional view of the entire utility model. Figure 4 This is a cross-sectional view of the auxiliary limiting structure of this utility model.
[0022] This utility model discloses a microbial culture preservation tube for laboratory use, comprising a tube body 101, multiple ceramic beads 102, and a sealing assembly. The sealing assembly includes a sealing cap 103, a sealing element 104, a threaded cap 105, an external threaded ring 106, two mating parts 107, an assembly ring 108, and two auxiliary limiting structures 109. Each auxiliary limiting structure 109 includes a limiting frame 110 and two fasteners 111. The sealing element 104 includes a plug ring 112, an expansion ring 113, and a sealing ring 114. The docking component 107 includes a connecting part 115 and a docking block 116. The fastener 111 includes an operating screw 117 and a limiting pin 118. The sealing assembly also includes a lifting ring 119 and an anti-slip skin 120. The aforementioned solution solves the problem that in existing bacterial culture preservation tubes, since the top cover is closed and sealed with the tube body 101 by rotation, if an error occurs during operation and causes the top cover to rotate, it will loosen with the tube body 101, thereby affecting the sealing effect of the tube body 101.
[0023] In this specific embodiment, a plurality of ceramic beads 102 are respectively located inside the tube body 101. The tube body 101 is used to store nutrient solution, and the ceramic beads 102 are used to store microbial strains. The method of using the ceramic beads 102 is described in the patent document with publication number CN201962287U, and will not be elaborated here.
[0024] The sealing cap 103 is located on one side of the tube body 101; the sealing element 104 is disposed on one side of the sealing cap 103; the threaded cap 105 is rotatably connected to the sealing cap 103 and is located on one side of the sealing cap 103; the external threaded ring 106 is fixedly connected to the tube body 101 and is located on one side of the tube body 101; two mating parts 107 are respectively disposed on both sides of the sealing cap 103; the assembly ring 108 is fixedly connected to the tube body 101 and is located on one side of the tube body 101; two auxiliary limiting structures 109 are respectively located on both sides of the assembly ring 108; the limiting frame 110 is fixedly connected to the assembly ring 108 and is located on one side of the assembly ring 108; two fasteners 111 are respectively disposed on one side of the limiting frame 110; the tube body 101 is used to store nutrient solution; and multiple ceramic beads 102 are used to store microorganisms. The bacterial culture is prepared, and then the sealing cap 103 is placed on top of the tube body 101. The threaded cap 105 is twisted to connect with the external threaded ring 106 on the tube body 101, causing the sealing element 104 on the sealing cap 103 to be inserted into the inner wall of the tube body 101 to seal the tube body 101. The two connecting parts 107 are respectively inserted into the limiting frames 110 on both sides of the tube body 101. After the connecting parts 107 are inserted, the fasteners 111 are used to further fix the connecting parts 107, thereby increasing the tightness of the closure between the sealing cap 103 and the tube body 101. This solves the problem that in existing bacterial culture preservation tubes, since the top cap is closed and sealed with the tube body 101 by rotation, if an error occurs during operation and the top cap rotates, it will loosen with the tube body 101, thus affecting the sealing effect of the tube body 101.
[0025] Secondly, the insertion ring 112 is fixedly connected to the sealing cap 103 and is located on one side of the sealing cap 103; the expansion ring 113 is fixedly connected to the insertion ring 112 and is located on one side of the insertion ring 112; the sealing ring 114 is fixedly connected to the expansion ring 113 and is located on one side of the expansion ring 113. The insertion ring 112 is used to insert into the tube body 101. The expansion force of the expansion ring 113 makes the sealing ring 114 fit tightly against the inner wall of the tube body 101, increasing the sealing performance between the sealing cap 103 and the tube body 101.
[0026] Furthermore, the connecting part 115 is fixedly connected to the sealing cover 103 and is located on one side of the sealing cover 103; the docking block 116 is fixedly connected to the connecting part 115 and is located on one side of the connecting part 115. The connecting part 115 is used to support the assembly of the docking block 116, and the docking block 116 is used to be inserted into the limiting frame 110.
[0027] In addition, the operating screw 117 is threadedly connected to the limiting frame 110 and is located on one side of the limiting frame 110; the limiting pin 118 is fixedly connected to the operating screw 117 and is located on one side of the operating screw 117. When the docking block 116 is inserted into the limiting frame 110, the operating screw 117 is twisted to drive the limiting pin 118 into the docking block 116, thereby completing the fixing of the docking block 116.
[0028] Furthermore, the lifting ring 119 is fixedly connected to the sealing cover 103 and is located on one side of the sealing cover 103; the anti-slip skin 120 is fixedly connected to the lifting ring 119 and is located on one side of the lifting ring 119. The lifting ring 119 and the anti-slip skin 120 are used to make it more convenient to operate the sealing cover 103 or lift the entire device.
[0029] In using this invention, the tube body 101 is used to store nutrient solution, and the multiple ceramic beads 102 are used to store microbial inoculum. Then, the sealing cap 103 is placed above the tube body 101, and the threaded cap 105 is twisted to connect with the external threaded ring 106 on the tube body 101. This causes the insertion ring 112 on the sealing cap 103 to insert into the inner wall of the tube body 101. The expansion force of the expansion ring 113, combined with the expansion force of the expansion ring 113, causes the sealing ring 114 to tightly adhere to the inner wall of the tube body 101, increasing the sealing performance between the sealing cap 103 and the tube body 101. Furthermore, the two connecting blocks 116 are... Do not insert the connecting block 116 into the limiting frames 110 on both sides of the tube body 101. After the connecting block 116 is inserted into the limiting frame 110, turn the operating screw 117 to drive the limiting pin 118 into the connecting block 116, thereby fixing the connecting block 116 and increasing the tightness of the sealing cap 103 and the tube body 101. This solves the problem that in existing bacterial culture preservation tubes, since the top cap is closed and sealed with the tube body 101 by rotation, if an error occurs during operation and the top cap rotates, it will loosen with the tube body 101, thus affecting the sealing effect of the tube body 101.

Those skilled in the art can understand that all or part of the processes for implementing the above embodiments and equivalent changes made in accordance with the claims of this application still fall within the scope of this application.
