[0029] Centrifuge tubes are commonly used laboratory instruments in biological and chemical laboratories, widely applied for sample separation, processing, preservation, and transfer. Existing centrifuge tubes are mainly divided into two types: one is the open-cap centrifuge tube, typically used for small tubes of 1.5mL, 2mL, and 0.5mL; the other is the screw-on centrifuge tube, mainly used for larger tubes of 15mL and 50mL. Currently, researchers typically need to use both hands to open centrifuge tubes. That is, one hand holds the centrifuge tube, while the other hand needs to open or screw on the cap. This method is particularly inconvenient in space-constrained environments, such as biosafety cabinets, glove boxes, and fume hoods, where researchers' hand movements are restricted. Existing centrifuge tube opening methods do not consider the need for single-handed operation, leading to reduced experimental efficiency.
[0030] To address the aforementioned technical problems, this utility model proposes a centrifuge tube opener, designed to assist operators in opening centrifuge tubes with one hand, thereby improving experimental efficiency.
[0031] As attached Figure 1 The diagram shown is a schematic representation of the overall structure of a centrifuge tube opener in one embodiment of this utility model; as shown in the attached diagram. Figure 2 As shown, Figure 1 A schematic diagram of the overall structure of the centrifuge tube cap opener from another angle; as attached. Figure 3 As shown, Figure 1 Enlarged view of point A in the middle; as attached. Figure 4 The diagram shown is a schematic representation of the overall structure of the centrifuge tube opener in another embodiment of this utility model; as shown in the attached diagram. Figure 5 As shown, Figure 4 A schematic diagram of the overall structure of the centrifuge tube cap opener from another angle. (See attached diagram) Figures 1-5 As can be seen from the diagram, the centrifuge tube opener includes a fixing part 1 and at least one opening part 2, with the opening part 2 connected to the fixing part 1.
[0032] The fixing part 1 is provided with a fixing member 11, which is used to connect to the wall surface so that the fixing part 1 is fixed to the wall surface. Since the opening part 2 is connected to the fixing part 1, the opening part 2 is also fixed to the wall surface so that the opening part 2 will not move when the operator opens the centrifuge tube, thereby enabling the centrifuge tube to be opened.
[0033] As attached Figure 2 and attachedFigure 5 As shown in the drawings, the cover opening part 2 is provided with a cover opening protrusion 212 and a cover opening groove 221, the cover opening protrusion 212 protrudes upward and is used to assist in prying open the cover of the centrifugal tube, the cover opening groove 221 has a downward opening and is used to assist in unscrewing the cover of the centrifugal tube. When the fixing part 1 is fixed to a wall surface, an operator can hold the centrifugal tube with one hand, place the cover of the centrifugal tube on the cover opening protrusion 212, and then move the centrifugal tube downward to open the cover, or place the cover of the centrifugal tube in the cover opening groove 221, fix the cover of the centrifugal tube by the cover opening groove 221, and then rotate the centrifugal tube to open the cover.
[0034] As can be seen from the above embodiment, the centrifugal tube cover opener can assist an operator in opening the cover of the centrifugal tube with one hand, thereby improving experimental efficiency.
[0035] In some embodiments, the groove wall of the cover opening groove 221 is provided with a rubber pad (not shown in the drawings) or an adhesive (not shown in the drawings), which can increase the friction between the cover of the centrifugal tube and the cover opening groove 221. An operator can place the cover of the centrifugal tube in the cover opening groove 221 to fix it, and then rotate the centrifugal tube to open the cover.
[0036] In some embodiments, the cover opening groove 221 is a regular polygon, and the cover opening groove 221 includes at least five sides. The shape of the regular polygon is close to a circle, which can accommodate a circular cover, and the edges of the polygon can increase the friction between the cover of the centrifugal tube and the cover opening groove 221, so that the cover of the centrifugal tube can be fixed when the centrifugal tube is rotated, thereby preventing the cover of the centrifugal tube from slipping.
[0037] As shown in the drawings, Figure 2 and the drawings, Figure 4 In some embodiments, the cover opening part 2 includes a first sub-cover opening part 21 and a second sub-cover opening part 22 connected to each other, the cover opening protrusion 212 is arranged on the first sub-cover opening part 21, the cover opening groove 221 is arranged on the second sub-cover opening part 22, one end of the first sub-cover opening part 21 is connected to the second sub-cover opening part 22, and the other end is a free end 211, and the cover opening protrusion 212 is located at the free end 211. When the cover of the centrifugal tube is of a pull-off type, an operator can open the cover of the centrifugal tube with one hand by placing the cover of the centrifugal tube against the cover opening protrusion 212 and then pulling the centrifugal tube downward. The cover opening protrusion 212 is located at the free end 211, so that the centrifugal tube is not blocked by other objects when it is pulled downward.
[0038] As shown in the drawings, Figure 3As shown, in some embodiments, the top of the cover opening protrusion 212 is provided with an edge 2121, the cover opening protrusion 212 comprises a first constituting surface 2122 and a second constituting surface 2123, and the first constituting surface 2122 and the second constituting surface 2123 intersect at the top of the cover opening protrusion 212 to form the edge 2121. The edge 2121 is easy to abut against the cover of the centrifugal tube, preventing the cover from slipping off the cover opening protrusion 212 when the centrifugal tube is pulled downward.
[0039] In some embodiments, the first constituting surface 2122 is parallel to the height direction, and the distance between the first constituting surface 2122 and the second cover opening part 22 is farther than the distance between the second constituting surface 2123 and the second cover opening part 22. When the centrifugal tube is pulled downward, the centrifugal tube is pulled downward along the height direction, and the design that the first constituting surface 2122 is parallel to the height direction can prevent the centrifugal tube from colliding with the first constituting surface 2122. Similarly, when the centrifugal tube is pulled downward, the design that the distance between the first constituting surface 2122 and the second cover opening part 22 is farther can prevent the centrifugal tube from colliding with the second cover opening part 22.
[0040] In some embodiments, the included angle between the second constituting surface 2123 and the first constituting surface 2122 is an acute angle, and the acute angle is easier to hook the cover of the centrifugal tube, preventing the cover from slipping off the cover opening protrusion 212 when the centrifugal tube is pulled downward.
[0041] In some embodiments, the thickness of the first cover opening part 21 in the height direction is smaller than the thickness of the second cover opening part 22 in the height direction. The second cover opening part needs to be hollowed out to form the cover opening groove 221, and the cover opening groove 221 needs a certain groove depth to fix the cover of the centrifugal tube. The thickness of the first cover opening part 21 can withstand the force of the centrifugal tube being pulled downward, so the thickness of the first cover opening part 21 can be designed to be smaller than the thickness of the second cover opening part 22, which can save the material of the first cover opening part 21 and will not affect the structural stability of the centrifugal tube opener.
[0042] As shown in the accompanying drawings, Figures 4-5 In some embodiments, the number of cover opening parts 2 is two, and the two cover opening parts 2 assist in opening the covers of centrifugal tubes of different models. The sizes of the covers of centrifugal tubes are different for different models of centrifugal tubes, and in order to assist in opening the covers of centrifugal tubes of multiple different models, the number of cover opening parts 2 can be designed to be two.
[0043] In some embodiments, one end of one of the two cover opening parts 2 is connected to the fixed part 1, and the other end is connected to the other cover opening part 2, that is, the two cover opening parts 2 and the fixed part 1 are connected in sequence, which can make the centrifugal tube opener smaller in size, and the two cover opening parts 2 do not affect each other when opening the covers.
[0044] The uncovering protrusions 212 of the two uncovering parts 2 are located at different heights, and the bottom surfaces of the second sub-uncovering parts 22 of the two uncovering parts 2 are located at different heights, so that the positions of the first sub-uncovering parts 21 and the second sub-uncovering parts 22 of the two uncovering parts 2 are staggered, and the two uncovering parts 2 do not affect each other when uncovering.
[0045] As shown in the accompanying drawings, Figure 1 In some embodiments, the fixing part 1 comprises parallel first and second surfaces 12 and 13, the uncovering part 2 is connected to the first surface 12, and the second surface 13 is provided with a fixing member 11, which comprises at least one of a magnet, an adhesive, a buckle, and a threaded fastener. The fixing member 11 is used to connect to a wall surface. For example, the fixing member 11 is a magnet, and the wall surface is a metal iron. The magnet and the metal iron are connected under the action of a magnetic force, and the magnet and the metal iron are detachable, facilitating the disassembly and connection of the fixing part 1 and the wall surface. The wall surface can be a wall surface of a biological safety cabinet, a glove box, or a fume hood.
[0046] The above description is only the preferred embodiment of the present application, and is not intended to limit the present application. Any modification, equivalent replacement, and improvement within the spirit and principle of the present application shall be included in the protection scope of the present application.
