Description

Technical Field

[0001] The utility model relates to the technical field of biological experimental instruments, in particular to a sealing device for a rubber plate. Background Art

[0002] In molecular biology experiments, an agarose gel is placed in an electrophoresis tank filled with electrophoresis buffer. DNA is then added to the wells of the agarose gel. Electrodes are inserted at both ends of the tank, and the DNA undergoes directional migration within the agarose gel. This type of experiment is called agarose electrophoresis in biological experiments. Agarose is a powder that undergoes a sol-gel operation to transform its form. This involves adding a certain amount of agarose powder to a heat-resistant container and a certain amount of electrophoresis buffer. The solution is then microwaved to form an agarose solution. The solution is then introduced into a sealed gel-making plate and allowed to cool and solidify into a specific agarose gel.

[0003] Currently, the gel plates need to be sealed manually with tape. Before electrophoresis, the tapes at both ends of the plates need to be torn off before agarose electrophoresis can be performed.

Failure to meet the sealing requirements will lead to the omission of agarose gel solution, affecting the quality of the agarose gel and thus the accuracy of DNA electrophoresis. It is labor-intensive and consumes a large amount of tape consumables. Utility Model Content

[0026] Reference below Figure 1-Figure 2 The sealing device 100 for the glue-making rubber plate according to the embodiment of the present invention is described. The sealing device 100 for the glue-making rubber plate greatly improves the convenience of the glue-making process, is convenient and fast, saves glue-making time, and the sealing device 100 is reusable, reducing material costs.

[0027] like Figure 1-Figure 2 As shown, a sealing device 100 for a rubber plate according to an embodiment of the present invention includes two sealing plates 1 and two telescopic structures 2 .

[0028] The sealing device 100 for a gelatinizing plate of the present invention can be used to prepare agarose gels, other colloids, and other applications requiring a sealed seal for a certain period of time. During the agarose gel preparation process, the gelatinizing plate is generally a rectangular structure with two sealed ends and one open end. The operator seals the open ends with tape to ensure the entire gelatinizing plate is sealed. An agarose solution can then be introduced into the plate, allowed to cool and solidify into an agarose gel of a specific shape, and the tape is then removed to proceed with agarose electrophoresis.

[0029] This method requires manual application and removal of tape, which is cumbersome, slow, and inefficient. The tape must be discarded after use, consuming a large amount of tape and resulting in high costs. Furthermore, the height of the tape seal must meet certain standards. Failure to meet these standards can result in leakage of the agarose gel solution, thereby affecting the quality of the agarose gel and, in turn, the accuracy of DNA electrophoresis. Therefore, the present invention provides a sealing device 100 for a gel-making plate to address this problem.

[0030] In the sealing device 100 for the rubber sheet, the two sealing plates 1 mainly play a sealing role and are used to seal the two open ends of the rubber sheet respectively. The two sealing plates 1 are spaced apart and relatively distributed along a first direction. The first direction can be the front-to-back direction, the left-to-right direction or other directions, so that the two sealing plates 1 can be relatively distributed along the front-to-back direction or the left-to-right direction.

[0031] Reference Attachment Figure 1 As shown, the first direction is Figure 1In the front-to-back direction shown in , the two sealing plates 1 are distributed at a certain distance along the front-to-back direction, one sealing plate 1 is located in the front, and the other sealing plate 1 is located in the back, to correspond to the two front and rear ports of the sealing rubber plate.

[0032] Furthermore, a telescopic structure 2 is connected between one end of the two sealing plates 1 and another sealing plate 1 is connected between the other ends of the two sealing plates 1 to jointly define an accommodating space 31 for accommodating the rubber plate.

[0033] That is, the two telescopic structures 2 are used to connect the two sealing plates 1. Figure 1 As shown, one telescopic structure 2 is connected between the left ends of the two sealing plates 1, and the other telescopic structure 2 is connected between the right ends of the two sealing plates 1, that is, the two telescopic structures 2 are respectively connected between the two ends of the two sealing plates 1, thereby forming a closed rectangular structure together. The closed space inside the structure is the accommodating space 31, which is used to accommodate and seal the glue-making rubber plate. The sealing device 100 is adapted to the shape of the glue-making rubber plate, which is conducive to tightly sealing the glue-making rubber plate, so that the sealing device 100 can be close to the glue-making rubber plate and close the two open ports, thereby improving the sealing effect, and the bottom of the sealing plate 1 is flush with the bottom of the glue-making rubber plate. In this way, when the agarose glue solution is introduced into the glue-making rubber plate, the agarose glue solution can be prevented from leaking out from the gap.

[0034] Furthermore, the sealing plate 1 is retractable relative to the retractable structure 2 along a first direction, and the two sealing plates 1 are moved closer to or farther away from each other to selectively close or open the two ports of the rubber plate.

[0035] That is to say, the two sealing plates 1 can telescopically move in the front-to-back direction relative to the two telescopic structures 2, so as to flexibly adjust the distance between the two sealing plates 1 to achieve the closure or opening of the two ports of the rubber plate, meet user needs, and be compatible with rubber plates of different sizes, with a wide range of applications.

[0036] Reference Attachment Figure 1As shown, when the two sealing plates 1 are shortened relative to the telescopic structure 2 in the front-to-back direction, the two sealing plates 1 approach each other, that is, one sealing plate 1 moves backward and the other sealing plate 1 moves forward, so that the two sealing plates 1 are respectively close to the two ports of the glue-making plate so that the two ports are closed, thereby sealing the glue-making plate. At this time, the agarose glue solution can be introduced into the glue-making plate to prepare agarose glue. When the two sealing plates 1 are extended relative to the telescopic structure 2 in the front-to-back direction, the two sealing plates 1 move away from each other, that is, one sealing plate 1 moves forward and the other sealing plate 1 moves backward, so that the two sealing plates 1 are respectively away from the two ports of the glue-making plate so that the two ports are opened. At this time, the glue-making plate can be removed, so that the glue-making plate is separated from the sealing device 100, and an agarose electrophoresis experiment can be performed. The sealing device 100 can be reused, which is flexible and convenient, reduces material costs, and saves glue-making time.

[0037] It should be noted that the sealing plate 1 can be manually pulled to extend and retract relative to the telescopic structure 2, or it can be automatically pulled to further free up hands, and can be flexibly selected according to actual needs. The retractable distance between the two sealing plates 1 and the height of the sealing plates 1 can be flexibly set according to actual needs. It is understood that the height of the sealing plate 1 should be at least equal to or higher than the port height of the glue-making rubber plate, and preferably higher than the port height of the glue-making rubber plate. In this way, the height of the sealing rubber plate can be higher than the height of the agarose sol, thereby preventing the sealing plate 1 from being too low and causing the agarose solution to leak out.

[0038] According to the sealing device 100 for the glue-making rubber plate in the embodiment of the present invention, the two sealing plates 1 and the two telescopic structures 2 cooperate with each other, so that the two sealing plates 1 can perform telescopic movement to flexibly adjust the distance between the two sealing plates 1, thereby realizing flexible closing and opening of the glue-making rubber plate ports, greatly improving the convenience of the glue-making process, being convenient and quick, saving glue-making time, and the sealing device 100 is reusable, reducing material costs.

[0039] In some embodiments, the end of the sealing plate 1 is provided with a telescopic portion 11 extending along the first direction, the telescopic structure 2 is formed with a telescopic fitting cavity open along the first direction, and at least a portion of the telescopic portion 11 is slidable along the first direction into the telescopic fitting cavity.

[0040] Specifically, if Figure 1 As shown, the first direction is Figure 1 In the front-to-back direction shown in the figure, the left and right ends of the sealing plate 1 are respectively provided with telescopic parts 11 extending along the front-to-back direction. The interior of the telescopic structure 2 is a cavity to form a telescopic fitting cavity, and the two ends of the telescopic fitting cavity are open along the front-to-back direction to facilitate connection with the telescopic parts 11 of the two sealing plates 1.

[0041] Among them, the size of the telescopic part 11 should be smaller than the size of the telescopic fitting cavity, so that the part of the telescopic part 11 away from the sealing plate 1 can extend into the telescopic fitting cavity and can slide smoothly in the telescopic fitting cavity along the front and rear directions. In practice, when the telescopic part 11 slides into the telescopic fitting cavity, the distance between the sealing plates 1 is correspondingly reduced, and when the telescopic part 11 slides out of the telescopic fitting cavity, the distance between the sealing plates 1 is correspondingly increased.

[0042] Therefore, the distance between the sealing plates 1 can be adjusted by sliding and retracting the telescopic part 11 in the telescopic fitting cavity, which is flexible and convenient. When in use, the sealing plate 1 can be directly pulled manually to drive the telescopic part 11 to move, thereby adjusting the sliding distance of the telescopic part 11, and then flexibly adjusting the distance between the sealing plates 1 to achieve the closure of different pairs of glue-making rubber plate ports. The operation is convenient and fast, and the glue-making efficiency is improved.

[0043] In some embodiments, the telescopic portion 11 is provided with a telescopic strip 111 , a telescopic guide groove 21 is formed in the telescopic fitting cavity, and the telescopic strip 111 extends into the telescopic guide groove 21 to slidably fit with the telescopic structure 2 .

[0044] Specifically, if Figure 2 As shown, the telescopic portion 11 is provided with a telescopic strip 111 in the direction of the telescopic fitting cavity, and a telescopic guide groove 21 is formed in the telescopic fitting cavity. The telescopic guide groove 21 is used to guide the telescopic strip 111 to slide. The telescopic guide groove 21 and the telescopic strip 111 are both along the first direction, that is, Figure 1 The telescopic strip 111 extends in the front-to-back direction as shown, which facilitates the movement of the telescopic strip 111 in the first direction. The telescopic strip 111 is adapted to the shape of the telescopic guide slot 21, and the length and width of the telescopic guide slot 21 should be slightly larger than the size of the telescopic strip 111, so that the telescopic strip 111 can smoothly extend into the telescopic guide slot 21 and slide smoothly.

[0045] Thus, by extending the telescopic strip 111 into the telescopic guide groove 21 to slide with the telescopic structure 2, stable telescopic movement along the first direction between the two sealing plates 1 is achieved, thereby achieving flexible adjustment of the distance between the two sealing plates 1, so that the two ports of the glue-making rubber plate can be flexibly closed and opened, thereby improving the glue-making efficiency and quality.

[0046] In some embodiments, there are multiple telescopic strips 111, that is, the number of telescopic strips 111 can be set to two, three or even more. Setting multiple telescopic strips 111 can enable the telescopic part 11 to perform telescopic movement under the action of multiple telescopic strips 111 at the same time, so that the force is more uniform, thereby improving the operation reliability and stability of the telescopic part 11.

[0047] The multiple telescopic bars 111 are spaced apart and distributed along the second direction, which is a direction intersecting or perpendicular to the first direction. In this way, the multiple telescopic bars 111 can each move stably without affecting or interfering with each other.

[0048] Furthermore, there are multiple telescopic guide grooves 21, that is, the number of telescopic guide grooves 21 can be set to two, three or even more. The number of telescopic guide grooves 21 should correspond to the number of telescopic strips 111, and the multiple telescopic guide grooves 21 are also spaced apart and distributed along the second direction, corresponding to the positions of the multiple telescopic strips 111. In this way, the multiple telescopic strips 111 can be extended into the multiple telescopic guide grooves 21 one by one, realizing a one-to-one correspondence with the multiple telescopic guide grooves 21, thereby improving the telescopic accuracy and stability of the sealing plate 1.

[0049] In some embodiments, the second direction is perpendicular to the first direction, that is, the sliding direction of each retractable strip 111 is perpendicular to its distribution direction.

[0050] Specifically, if Figure 1 and Figure 2 As shown, the first direction is the front-to-back direction, and the second direction is the left-to-right direction, that is, the second direction is perpendicular to the first direction. The first direction is the direction in which the two sealing plates 1 are spaced apart and relatively distributed, and is also the main direction in which the telescopic structure 2 drives the sealing plate 1 to perform telescopic movement, and is also the sliding movement direction of the multiple telescopic strips 111. The second direction is the direction in which the multiple telescopic strips 111 and the multiple telescopic guide grooves 21 are spaced apart and distributed. Setting these two directions perpendicularly not only improves the accuracy and stability of telescopic expansion, but also enables the sealing device 100 to be more evenly stressed when closing the glue-making rubber plate port, thereby reducing the risk of glue leakage.

[0051] In some embodiments, the telescopic bar 111 is constructed as a driven rack, and a driving gear is provided in the telescopic structure 2. The driving gear engages with the telescopic bar 111 and is suitable for pushing the telescopic bar 111 to slide relative to the telescopic guide slot 21.

[0052] That is to say, the telescopic bar 111 is constructed as a driven rack with evenly arranged teeth on one or both sides, which is engaged with a driving gear (not shown in the figure) so that when the driving gear rotates, it can drive the driven rack to move linearly along the first direction, that is, slide linearly in the telescopic guide groove 21, thereby realizing the extension or retraction of the telescopic bar 111.

[0053] Therefore, the telescopic movement of the sealing plate 1 is achieved by cooperating with the driven rack and the driving gear, which can make the movement of the sealing plate 1 smoother, thereby better controlling the distance between the two sealing plates 1. That is to say, when the distance between the two sealing plates 1 reaches the user's required distance, the sealing plate 1 can remain stable, and the telescopic strip 111 will not continue to slide in the telescopic guide groove 21, thereby avoiding the instability of the sealing plate 1 caused by the telescopic strip 111 slipping in the telescopic guide groove 21, thereby improving the sealing effect of the rubber plate, so that the sealing plate 1 can stably and tightly seal the two ports of the rubber plate.

[0054] In some embodiments, the telescopic structure 2 is further provided with a telescopic motor, the motor shaft of the telescopic motor is connected to the driving gear, and the telescopic motor is used to drive the driving gear to rotate.

[0055] That is, the telescopic motor (not shown in the figure) is a power source, which can provide power to the driving gear to drive the driving gear to rotate. In practice, when the telescopic motor is started, its motor shaft rotates to drive the driving gear to rotate, thereby realizing power transmission from the telescopic motor to the driving gear, and then the rotation of the driving gear can push the telescopic bar 111 to slide relative to the telescopic guide groove 21.

[0056] Therefore, the sealing plate 1 can be automatically extended and retracted by providing a telescopic motor, without the need for manual pushing and pulling of the sealing plate 1, thereby further freeing the hands and providing flexibility and convenience.

[0057] In some embodiments, the telescopic fitting cavity passes through the telescopic structure 2 along the first direction, and the telescopic portions 11 of the two sealing plates 1 extend into the telescopic fitting cavity from two ends thereof, respectively.

[0058] Specifically, if Figure 1 As shown, the first direction is Figure 1 In the front-to-back direction shown in the figure, the telescopic fitting cavity passes through the telescopic structure 2 along the front-to-back direction, and the two ends of the telescopic fitting cavity are respectively open toward the telescopic parts 11 of the two sealing plates 1. In this way, the telescopic parts 11 of the two sealing plates 1 can be respectively extended from the two ends of the telescopic fitting cavity to cooperate with the telescopic guide groove 21, that is, the telescopic parts 11 on the left or right side of the two sealing plates 1 can be simultaneously extended into the telescopic fitting cavity to cooperate with their respective corresponding telescopic guide grooves 21, which improves the compactness of the structure and makes the overall structure of the sealing device 100 simpler and more convenient.

[0059] In some embodiments, each telescopic structure 2 is provided with a driving member, and the driving member is used to drive the sealing plate 1 to extend and retract relative to the telescopic structure 2 .

[0060] That is to say, both telescopic structures 2 are provided with a driving member, which can provide power to drive the two sealing plates 1 to perform telescopic movement relative to the two telescopic structures 2, thereby flexibly changing the distance between the two sealing plates 1 to achieve sealing of the rubber plate and meet the user's rubber making requirements.

[0061] The driving member can be electric, pneumatic, hydraulic or other types of driving devices, which can be flexibly selected according to actual conditions.

[0062] In some embodiments, the two telescopic structures 2 are symmetrically distributed.

[0063] That is, the two telescopic structures 2 are identical and symmetrically connected at the two ends of the two sealing plates 1. The symmetrical distribution of the two telescopic structures 2 not only enhances the stability of the sealing device 100, but also enables the two sealing plates 1 to maintain balance during movement, avoiding tilting and inconsistent distances between the two ends of the two sealing plates 1, resulting in a gap at one end, etc., thereby avoiding affecting the sealing effect of the rubber plate and preventing solution leakage.

[0064] In other embodiments, the two sealing plates 1 are symmetrically distributed.

[0065] That is, the two sealing plates 1 are identical and symmetrically distributed along the front-to-back direction, which further enhances the balance and stability of the sealing device 100 and helps improve the sealing effect. Figure 1 As shown, two sealing plates 1 symmetrically distributed along the front-to-back direction and two telescopic structures 2 symmetrically distributed along the left-to-right direction together form a rectangular body, the front and back sides of which can be tightly attached to the two ends of the rubber plate to tightly seal the two ports.

[0066] Of course, the sealing device 100 can also be set to other structural shapes. As long as the telescopic effect of the telescopic structure 2 is used to adjust the distance between the sealing plates 1 to achieve the closing or opening of the rubber plate port, it is within the protection scope of the present invention.

[0067] The following are steps for preparing agarose electrophoresis gel using the sealing device 100 for preparing agarose electrophoresis gel of the present invention:

[0068] (1) Seal the rubber sheet, that is, seal the two ports of the rubber sheet, and leave the other two ports unsealed and open. At the same time, place the sealing device 100 in its initial state, that is, when the distance between the two sealing plates 1 is the smallest and in a contracted state. Then, place the two open ports of the rubber sheet on one side of the two sealing plates 1, stretch the two sealing plates 1 so that the distance between the two sealing plates 1 increases until it is greater than the distance between the two open ports of the rubber sheet, and then place the rubber sheet in the sealing device 100. Then, push the two sealing plates 1 in the opposite direction so that the two sealing plates 1 move toward each other until the two sealing plates 1 contact the rubber sheet to seal the two open ports. At this time, the sealing device 100 and the rubber sheet together form a closed space.

[0069] (2) Then, the agarose gel solution is introduced into the gel-making rubber plate with the sealing device 100 installed, and the gel is left to stand and wait until the agarose gel solution cools down to solid agarose gel, and then the comb can be carefully pulled out.

[0070] (3) Then, the two sealing plates 1 are gently stretched to a distance beyond the two ports of the rubber plate, so that the two ports of the rubber plate are in an open state. At the same time, the stretched state of the sealing device 100 is kept unchanged, and the sealing device 100 is vertically lifted above the rubber plate to separate the sealing device 100 from the rubber plate. Then, the sealing device 100 can be restored to its original state again.

[0071] (4) The surface of the sealing device 100 is then cleaned and waits for reuse.
