Technical Field

[0001] This application relates to the field of experimental apparatus technology, and in particular to a lid-opening device. Background Technology

[0002] Centrifugation is a physical technique that uses high-speed rotation to generate centrifugal force, separating different components in a mixture. It is widely used in biology, chemistry, and medicine. Centrifuge tubes, also known as PCR tubes or PE tubes, are commonly used in centrifugation to hold mixtures. To use them, first open the cap, then add the mixture to the tube, close the cap again, and place the prepared centrifuge tube into a centrifuge apparatus for rotation and separation, obtaining the stratified mixture.

[0003] In related technologies, cap openers are generally used to open centrifuge tubes containing stratified materials to reduce potential contamination from manual opening. However, traditional cap openers can only open single tube caps, making their function relatively limited. Opening multiple tube caps requires purchasing a separate multi-row cap opener, resulting in high operating costs. Utility Model Content

[0025] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0026] See Figure 1 and Figure 2This application provides a cover opening device, comprising: a first cover opening member 100, having a connecting pipe cover groove 101 extending along a first direction X of the first cover opening member 100; a second cover opening member 200 connected to the first cover opening member 100, having a plurality of single-pipe cover holes 201 extending along a second direction Z of the first cover opening member 100, the plurality of single-pipe cover holes 201 being spaced apart along the first direction X; wherein the line containing the first direction X is perpendicular to the line containing the second direction Z; and a handheld member 300 connected to the first cover opening member 100 and / or the second cover opening member 200. The connecting pipe cover groove 101 includes a clearance groove 1011 and a receiving groove 1012. The clearance groove 1011 is located outside the first opening member 100 and is used to clear the connecting pipe head. The receiving groove 1012 communicates with the clearance groove 1011 in the second direction Z, and the projected area of ​​the clearance groove 1011 in the second direction Z falls within the projected area of ​​the receiving groove 1012 in the second direction Z. The clearance groove 1011 includes eight arc-shaped surfaces arranged in two rows at intervals. The two opposing arc-shaped surfaces enclose a clearance space for the connecting pipe head to pass through. The first opening member 100 is also provided with a pressing groove 102, which is arranged opposite to the connecting pipe cover groove 101 in the second direction Z. The first opening member 100 and the second opening member 200 are integrally formed. The single-tube cover hole 201 includes a first cover hole 2011 and a second cover hole 2012. The size of the first cover hole 2011 is smaller than the size of the second cover hole 2012, and the first cover hole 2011 is located away from the first cover opening member 100. The single-tube cover hole 201 also includes a third cover hole 2013. The size of the third cover hole 2013 is larger than the size of the second cover hole 2012, and the second cover hole 2012 is located away from the first cover opening member 100.

[0027] This embodiment provides a capping device that effectively avoids human hand contact with centrifuge tubes containing stratified material. This device can open the caps of multi-tube sets using the first capping component 100, open the caps of single tubes using the second capping component 200, and simultaneously open multiple caps of multiple single tubes, offering a wide range of functions. Furthermore, only one capping device is needed to meet multiple usage scenarios, resulting in low operating costs. In addition, a handheld component 300 is provided for the user to hold the capping device, facilitating operation and providing a superior user experience.

[0028] Specifically, the cover opening device is configured as a combination of at least a first cover opening component 100, a second cover opening component 200, and a handheld component 300. The first cover opening component 100 can be a plate-like structure with a pipe cover groove 101 for opening the pipe cover of a multi-connected pipe. The pipe cover groove 101 includes a clearance groove 1011 and a cover receiving groove 1012 stacked and connected vertically. The clearance groove 1011 is generally in the form of a corrugated groove, with eight continuously bent arc-shaped surfaces in the first direction X forming a corrugated wall. There are two sets of corrugated walls, which are opposite to each other and spaced apart, to enclose eight nearly circular clearance holes for clearing eight-connected pipes or six-connected pipes, etc. The cap groove 1012 is generally rectangular in shape, penetrating the first opening member 100 along the first direction X, and communicating with the bottom of the relief groove 1011 in the second direction Z. Furthermore, the relief groove 1011 extends to both sides in the third direction Y to engage the pipe cap, allowing the pipe cap of the multi-connected pipe to be unscrewed when the opening device is flipped. In addition, to enrich the function of the opening device, a clamping groove 102 is provided on the first opening device, which is positioned opposite to the cap groove 1012. Figure 2 As shown, the depth of the compression groove 102 is relatively shallow, only enough to accommodate the thickness of the pipe cap in the second direction Z. In this way, when it is necessary to close the cap, the pipe cap of the multi-pipe or single pipe can be placed in the compression groove 102, and the pipe cap can be pressed down by the cap opening device to avoid contamination of the material inside the multi-pipe or single pipe by human hand contact. The second opening component 200 can be a plate-like structure with multiple single-tube cap holes 201. Each single-tube cap hole 201 can open the cap of one single tube. The single-tube cap hole 201 penetrates the second opening component 200 in the second direction Z. When opening the cap, the single tube is fixed, and then the protruding part of the single tube cap is inserted into the single-tube cap hole 201. Rotating the opening device opens the cap. The single-tube cap holes 201 can be of various models to accommodate single tubes of different sizes, such as 0.2mL, 0.6mL, 1.5mL, etc., increasing the number of single tubes that can be opened. Multiple single-tube cap holes 201 of each model can be provided to open multiple single tubes of the same size simultaneously, saving opening time and improving efficiency. The handheld component 300 can be a plate-like structure or a tubular structure. It is provided on the first opening component 100 or the second opening component 200, or both, to provide a handheld area for the user and improve ease of use.

[0029] In one example, the single-tube cap holes 201 can be arranged with increasing diameters in the direction close to the first opening member 100. In this way, by placing the smallest single-tube cap hole 201, which is the most difficult to operate, on the outermost side, the difficulty of alignment for the user can be reduced, the difficulty of opening the cap can be reduced, and the efficiency of opening the cap can be improved.

[0030] In one example, to facilitate manufacturing and improve the overall aesthetics of the lid-opening device, the first lid-opening component 100 and the second lid-opening component 200 can be integrally molded. This eliminates gaps at the connection point, resulting in a more aesthetically pleasing appearance and a longer service life.

[0031] It should be explained that the first direction X can refer to the length direction of the first cover 100, the second direction Z can refer to the thickness direction of the first cover 100, and the third direction Y can refer to the width direction of the first cover 100.

[0032] like Figure 1 and Figure 2 As shown, in one possible implementation, the second cover member 200 includes an upper perforated plate 210 and a lower perforated plate 220 that is spaced apart from the upper perforated plate 210 in the second direction Z. A plurality of single-tube cap holes 201 located on the upper perforated plate 210 correspond one-to-one with a plurality of single-tube cap holes 201 located on the lower perforated plate 220.

[0033] In this embodiment, a clamping cap opening structure is provided. The second cap opening member 200 is configured to include at least an upper perforated plate 210 and a lower perforated plate 220. The upper perforated plate 210 has a plurality of single-tube cap holes 201, and the lower perforated plate 220 has a corresponding plurality of single-tube cap holes 201. The two perforated plates are spaced apart in the second direction Z to at least reserve the radial dimension of the tube head, thereby forming a clamping plate structure on one side of the first cap opening member 100. This clamping plate structure can improve the stability and reliability of single-tube cap opening. When opening the cap, the single tube is inserted into the gap between the upper perforated plate 210 and the lower perforated plate 220, and the tube cap protrusion of the single tube extends into the single-tube cap hole 201 corresponding to one of the perforated plates. The other perforated plate abuts against the outer wall of the tube body. The cap opening device is rotated. At this time, the tube body of the single tube is fixed by the perforated plate, and the tube cap of the single tube is driven and opened by the other perforated plate, making the entire cap opening process more reliable.

[0034] In one possible implementation, the handle 300 is located on the side of the first opening member 100 away from the second opening member 200, and the length of the handle 300 in the first direction X is equal to the length of the first opening member 100 in the first direction X. Figure 1 or Figure 2 As shown; or, the handle 300 is disposed on the side of the second opening member 200 away from the first opening member 100, and the length of the handle 300 in the first direction X is equal to the length of the second opening member 200 in the first direction X. The handle 300 can be bonded or welded to the end of the first opening member 100 or the second opening member 200, or it can be integrally formed with the first opening member 100 or the second opening member 200. This example forms a long plate-type opening device by setting the handle 300 as a plate-like structure extending along the first direction X, resulting in a better opening effect.

[0035] In one example, such as Figure 1 and Figure 2 As shown, a clearance hole 301 can be provided on the handheld component 300. The clearance hole 301 penetrates the handheld component 300 in the second direction Z to provide handheld space for the user and make it convenient for the user to pick up the item.

[0036] In one possible implementation, a handle 300 is disposed on the side edge of the first opening member 100 and the second opening member 200. The length of the handle 300 in the third direction Y of the first opening member 100 is equal to the total length of the first opening member 100 and the second opening member 200 in the third direction Y; wherein the line containing the third direction Y is perpendicular to the line containing the first direction X and the line containing the second direction Z. The handle 300 can be bonded or welded to the end of the first opening member 100 or the second opening member 200. In this example, the handle 300 is provided with a plate-like structure extending in the third direction Y, forming a near-rectangular plate-like opening device, which is beneficial for saving storage space.
