Description

Technical Field

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

[0002] Centrifuge tubes are tubular sample containers. When placed in a centrifuge, the suspended microparticles in the centrifuge's high-speed rotation cause them to settle at a certain speed, thus separating them from the solution.

[0003] However, existing centrifuge tubes require multiple tubes to be prepared when centrifuging various samples, which is cumbersome, affects the work efficiency of staff, and does not provide adequate protection for the centrifuge tubes. Therefore, they do not meet the current needs, and we have proposed a new centrifuge tube. Utility Model Content

[0004] The purpose of this invention is to provide a centrifuge tube that solves the problems mentioned in the background art, such as the need to prepare multiple centrifuge tubes when centrifuging various samples, which is cumbersome, affects the work efficiency of staff, and does not provide adequate protection for the centrifuge tubes.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a centrifuge tube, comprising a main body, a counterweight base at the lower end of the main body, a connecting ring on the outer side of the upper end of the main body, positioning rods evenly arranged between the connecting ring and the counterweight base, a rubber block between the positioning rod and the main body, a connecting plate at the upper end of the main body, Velcro on the outer surface of the connecting plate, a cover plate above the connecting plate, a sealing block on the lower surface of the cover plate, a slot on the inner side of the connecting plate, the main body and the slot being connected by threads, a disposable connecting tube on the inner side of the main body, a connecting groove on one side of the slot, positioning blocks evenly arranged on the inner surface of the connecting groove, elastic balls on the upper surface of the positioning blocks, limiting grooves evenly arranged on the inner surface of the upper end of the disposable connecting tube, a positioning groove on the inner surface of the upper end of the disposable connecting tube located between two adjacent limiting grooves, an O-ring seal between the disposable connecting tube and the lower end of the connecting groove, and an anti-slip pad on the lower surface of the counterweight base.

[0006] Preferably, the lower end of the positioning rod is fully fitted with the upper surface of the counterweight base, and the positioning rod and the counterweight base are fixed by screws.

[0007] Preferably, the inner surface of the connecting ring is completely fitted with the outer surface of the main body, and the connecting ring and the main body are fixed by welding.

[0008] Preferably, a sealing ring is provided between the outer surface of the sealing block and the inner surface of the connecting plate.

[0009] Preferably, one side of the positioning block is completely fitted with the inner surface of the connecting groove, and the positioning block is fixed to the inner wall of the connecting groove by welding.

[0010] Preferably, one side of the rubber block is completely attached to the outer surface of the main body, and the rubber block is fixed to the main body by welding.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, by setting a counterweight base under the main body, can ensure that the base at the bottom of the main body lands first when the main body falls, thus reducing wear and tear on the main body during the fall. It also increases the protection of the main body and extends its service life by using the rubber block and positioning rod set on the outside of the main body.

[0013] 2. This utility model uses a limiting groove and a positioning groove set at the upper end of the disposable connecting tube. The positioning block in the connecting groove is inserted into the limiting groove, and then the disposable connecting tube is rotated to connect the positioning block with the positioning groove. At this time, the disposable connecting tube is connected to the connecting plate, and then the connecting plate is connected to the main body. When centrifuging multiple samples, it is not necessary to replace the main body one by one. Only the connecting plate needs to be removed and the disposable connecting tube replaced, which reduces the labor intensity of the staff, improves the work efficiency of the staff, and reduces the cleaning difficulty of the staff.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Please see Figures 1 to 3This utility model provides an embodiment of a centrifuge tube, comprising a main body 7, a counterweight base 8 at the lower end of the main body 7, a connecting ring 4 on the outer side of the upper end of the main body 7, positioning rods 5 evenly arranged between the connecting ring 4 and the counterweight base 8, a rubber block 6 between the positioning rod 5 and the main body 7, a connecting plate 2 at the upper end of the main body 7, Velcro 3 on the outer surface of the connecting plate 2, a cover plate 1 above the connecting plate 2, a sealing block 9 on the lower surface of the cover plate 1, and a slot 10 on the inner side of the connecting plate 2. The main body 7 and the slot 10 are connected by threads. The connection is as follows: a disposable connecting tube 11 is provided on the inner side of the main body 7; a connecting groove 17 is provided on one side of the slot 10; positioning blocks 15 are evenly provided on the inner surface of the connecting groove 17; elastic balls 16 are provided on the upper surface of the positioning blocks 15; limiting grooves 18 are evenly provided on the inner surface of the upper end of the disposable connecting tube 11; a positioning groove 13 is provided on the inner surface of the upper end of the disposable connecting tube 11 between two adjacent limiting grooves 18; an O-ring seal 14 is provided between the lower end of the disposable connecting tube 11 and the connecting groove 17; and an anti-slip pad 12 is provided on the lower surface of the counterweight base 8.

[0020] Furthermore, the lower end of the positioning rod 5 is fully attached to the upper surface of the counterweight base 8, and the positioning rod 5 and the counterweight base 8 are fixed by screws.

[0021] By adopting the above technical solution, the support effect of the positioning rod 5 is increased, and the protection of the main body 7 is improved.

[0022] Furthermore, the inner surface of the connecting ring 4 is completely fitted with the outer surface of the main body 7, and the connecting ring 4 and the main body 7 are fixed by welding.

[0023] By adopting the above technical solution, the connection strength of the connecting ring 4 is increased, and the working strength of the connecting ring 4 is improved.

[0024] Furthermore, a sealing ring is provided between the outer surface of the sealing block 9 and the inner surface of the connecting plate 2.

[0025] By adopting the above technical solution, the sealing performance of the sealing block 9 connection is increased, and the working effect of the sealing block 9 is improved.

[0026] Furthermore, one side of the positioning block 15 is completely fitted with the inner surface of the connecting groove 17, and the positioning block 15 is fixed to the inner wall of the connecting groove 17 by welding.

[0027] By adopting the above technical solution, the robustness of the connection of the positioning block 15 is increased, and the working strength of the positioning block 15 is improved.

Then, the disposable connecting tube 11 is rotated to connect the positioning block 15 with the positioning groove 13. At this time, the disposable connecting tube 11 is connected to the connecting plate 2. Then, the connecting plate 2 is connected to the main body 7. When centrifuging multiple samples, it is not necessary to replace the main body 7 one by one. Only the connecting plate 2 needs to be removed and the disposable connecting tube 11 replaced, which reduces the labor intensity of the staff, improves the work efficiency of the staff, and reduces the cleaning difficulty.
