Description

Technical Field

[0001] This utility model relates to the field of centrifuge tube technology, specifically a centrifuge tube with enhanced sealing performance. Background Technology

[0002] Centrifuge tubes are a type of small-volume test tube commonly used in laboratories. They are typically used for centrifugation, sample storage, and fluid replacement. Centrifuge tubes are also frequently used for sample preservation and transportation. Choosing the right centrifuge tube material and capacity can ensure that samples are not damaged or contaminated during preservation and transportation.

[0003] Current centrifuge tubes generally consist of a tube body and a plug inserted into the inner wall of the tube body. The plug has an edge on its surface, and the user can pull the plug out of the inner wall of the tube body by pinching the edge. However, during the transportation of centrifuge tubes, if an external force hits the edge, it may pull the plug out of the inner wall of the tube body, thereby causing leakage of the contents of the tube body. Therefore, a new type of centrifuge tube with enhanced sealing is needed to solve the above problems. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that when transporting centrifuge tubes, if an external force hits the edge of the centrifuge tube plug surface, the plug may be pulled out of the inner wall of the tube, causing leakage of the contents inside the tube. This utility model provides a centrifuge tube.

[0005] To achieve the above objectives, this utility model specifically adopts the following technical solution:

[0006] A centrifuge tube with enhanced sealing includes: a storage tube with a plug disposed above the storage tube, and a limiting unit for limiting the position of the plug on the inner wall of the storage tube, wherein a pinching tab is slidably inserted into the surface of the plug.

[0007] Furthermore, the storage tube includes a main body, and the surface of the main body is provided with a graduated groove.

[0008] Furthermore, the limiting unit includes two limiting rings disposed at the bottom of the plug, and limiting protrusions are provided on the surface and inner wall of the main body, with the two limiting protrusions slidably inserted into the surfaces of the two limiting rings respectively.

[0009] Furthermore, the surface of the plug is provided with a slot, the pinching piece is slidably inserted into the inner wall of the slot and a rubber block is fixedly installed on its surface, the inner wall of the slot is provided with a through groove, and the rubber block is slidably inserted into the inner wall of the through groove.

[0010] Furthermore, an elastic sheet is fixedly installed on the surface of the plug, and the other end of the elastic sheet is fixedly installed on the surface of the main tube.

[0011] Furthermore, one end of the pinching piece is provided with a hook.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. In this utility model, a plug is set above the storage tube. During use, the user needs to restrict the plug to the inner wall of the storage tube using a limiting unit. When the plug needs to be removed later, the user can pinch the pinching piece to pull the plug out of the storage tube. When transporting the storage tube, the user can insert the pinching piece back into the plug before transporting the storage tube. During subsequent transportation, because the pinching piece has been retracted into the plug, foreign objects cannot hit the surface of the pinching piece and drive the plug away from the storage tube, thus avoiding leakage of the contents of the main tube.

[0014] 2. In this utility model, a slot is opened on the surface of the plug, and the pinch piece is slidably inserted into the inner wall of the slot. A through groove is opened on the inner wall of the slot. When in use, the user slides the rubber block fixedly installed on the surface of the pinch piece, so that the rubber block slides on the inner wall of the through groove, which can quickly drive the pinch piece to slide on the inner wall of the slot.

[0020] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings.

[0021] This embodiment provides a centrifuge tube, primarily designed to address the problem that during centrifuge tube transportation, if an external force impacts the edge of the centrifuge tube plug, it may be dislodged from the inner wall of the tube, causing leakage of the contents. The following technical solution is provided in conjunction with... Figures 1-4 Please provide a detailed explanation:

[0022] A centrifuge tube with enhanced sealing includes: a storage tube 1 with a plug 2 at the top. During use, the user needs to use a limiting unit 3 to restrict the plug 2 to the inner wall of the storage tube 1. When it is necessary to open the plug 2 later, the user can pinch a sliding pry piece 4 inserted into the inner wall of the storage tube 1 to pull the plug 2 out. Simultaneously, during transportation of the storage tube 1, the pry piece 4 can be inserted back into the storage tube 1. Even if a foreign object impacts the layered surface, the plug 2 will not be pulled out from the inner wall of the storage tube 1. The main component of the storage tube 1 is: a main tube body 11 with graduated grooves 12 on its surface, which the user can... The object is placed on the inner wall of the main body 11, and the amount of the object inside the main body 11 is determined by the scale groove 12. The main components of the limiting unit 3 are: two limiting protrusions 32 respectively set on the surface and inner wall of the main body 11. In use, the user can slide the two limiting rings 31, which are both set on the inner wall of the plug 2, into the inner wall of the main body 11 and slide them onto the surface of the main body 11, so that the two limiting protrusions 32 slide into the surface of the two limiting rings 31, thereby limiting the plug 2 above the main body 11. It should be noted that the material of the two limiting rings 31 is elastic material.

[0023] By setting a plug 2 above the storage tube 1, the user needs to restrict the plug 2 to the inner wall of the storage tube 1 using the limiting unit 3. When the plug 2 needs to be removed later, the user can pinch the pinching piece 4 to pull the plug 2 out of the storage tube 1. When transporting the storage tube 1, the user can insert the pinching piece 4 back into the plug 2 before transporting the storage tube 1. During subsequent transportation, because the pinching piece 4 has been retracted into the plug 2, foreign objects cannot hit the surface of the pinching piece 4 and drive the plug 2 away from the storage tube 1, thus avoiding leakage of objects inside the main body 11.

[0024] By opening a slot 5 on the surface of the plug 2, the pinch piece 4 is slidably inserted into the inner wall of the slot 5, and a through groove 7 is provided on the inner wall of the slot 5. When in use, the user slides the rubber block 6 fixedly installed on the surface of the pinch piece 4, so that the rubber block 6 slides on the inner wall of the through groove 7, which can quickly drive the pinch piece 4 to slide on the inner wall of the slot 5.

[0025] like Figure 3As shown, in some embodiments, a slot 5 is provided on the surface of the plug 2, and the pinch piece 4 is slidably inserted into the inner wall of the slot 5. In use, the user presses the rubber block 6 fixedly installed on the surface of the pinch piece 4, so that the rubber block 6 slides on the inner wall of the through groove 7 opened in the inner wall of the slot 5, thereby driving the pinch piece 4 on the inner wall of the slot 5. Since both the pinch piece 4 and the rubber block 6 are made of rubber, both the pinch piece 4 and the rubber block 6 can remain stationary on the inner walls of the slot 5 and the through groove 7. It should be noted that a hook 9 is provided at one end of the pinch piece 4. When the user pinches the pinch piece 4, his / her fingers will touch the surface of the hook 9, which makes it easier to pull the pinch piece 4.

[0026] like Figure 2 and Figure 3 As shown, in some embodiments, an elastic piece 8 is fixedly installed on the surface of the plug 2, and the other end of the elastic piece 8 is fixedly installed on the surface of the main tube 11. Therefore, when the user pulls the plug 2 out from the inner wall of the main tube 11, it will be on one side of the main tube 11 and will not fall off.

[0027] The working process of this utility model is as follows:

[0028] First, the user needs to pinch the pinching piece 4, pull the plug 2, and pull it out of the inner wall of the main body 11. Then, place an object inside the main body 11 and judge the amount of the object inside the main body 11 through the scale groove 12.

[0029] Secondly, when transporting this device, the user needs to insert the pinch piece 4 back into the inner wall of the slot 5. During subsequent transportation, no foreign objects will hit the surface of the pinch piece 4, thereby causing the plug 2 to fall off the inner wall of the main body 11 and causing foreign objects to leak. When it is necessary to remove the object inside the main body 11, the user needs to press the rubber block 6 to make the pinch piece 4 slide on the inner wall of the slot 5, so that the pinch piece 4 is exposed from the inner wall of the slot 5. Then the user can pinch the pinch piece 4 and pull the plug 2.

[0030] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
