Description

Technical Field

[0001] This application relates to the technical field of electrophoresis experiment tools, and particularly to a link mechanism gel preparation fixture. Background Art

[0002] The phenomenon that charged particles move towards the electrode with the opposite electric property under the action of an electric field is called electrophoresis. Electrophoresis technology is an important part of molecular biology research and molecular biology experiments. Gel electrophoresis is a commonly used experimental technique for identifying, quantifying, and purifying nucleic acids in molecular biology. It applies an electric field on a gel matrix, and the gel acts as a molecular sieve under the action of the electric field force. Biomolecules (such as nucleic acids and proteins) can be separated through their differential migration rates. Therefore, reliable and fast gel preparation is the primary prerequisite for electrophoresis applications.

[0003] Currently, gels are usually prepared by stacking a planar short glass and a long concave glass with convex strips at both ends (forming a gel-making glass assembly). During preparation, a gel preparation fixture is used to align and align the planar short glass and the long concave glass, and the clamping force is used to make the two ends of the planar short glass closely fit and seal with the convex strips of the long concave glass, and a seal is used to seal the bottom surfaces of the two glass sheets, so that a chamber with five-sided sealing and an open top is formed in the middle of the gel-making glass assembly. Gel liquid is poured at the open top, and the gel can be obtained after the gel liquid cools.

[0004] However, in related technologies, passive cams or wedge-shaped structures are generally used, and the clamping between glass sheets is realized by relying on the elastic force of the fixture. Due to the insufficient elastic force of the fixture and the instability of the elastic force of the fixture, the glass sheets are often not clamped tightly, resulting in liquid leakage. At the same time, since the fixture is required to clamp the glass sheets in two directions, related technologies generally adopt a two-step operation method. First, clamping in one direction is realized, and then clamping in another perpendicular direction is realized. The two clamping operations are prone to problems such as unfixed clamping force and low clamping reliability. The above two disadvantages often lead to liquid leakage, and the gel-making operation fails, bringing great inconvenience to scientific research and production personnel.

[0036] To make the objectives, technical solutions, and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described in more detail below with reference to the accompanying drawings in the embodiments of the present application. It should be noted that the embodiments described in the accompanying drawings are only a part of the embodiments of the present application, rather than all the embodiments. That is, the embodiments described through the accompanying drawings are exemplary and are intended to explain the present application, rather than being construed as a limitation to the present application.

[0037] The following will be combined with Figures 1-5 to describe the link mechanism gel preparation fixture 100 provided by the embodiment of the present application.

[0038] The embodiment of the present application provides a link mechanism gel preparation fixture 100, as Figures 1-4 shown, including a machine base, a sealing frame assembly 120, a pressing link mechanism 130, and a power mechanism.

[0039] The machine base includes a base 110 and a receiving seat 114. The receiving seat 114 is spaced above the base 110, and the receiving seat 114 is provided with a long receiving hole 115 that penetrates up and down for placing the gel-making glass assembly 200.

[0040] The sealing frame assembly 120 is detachably fixed in the gap between the base 110 and the receiving seat 114 for sealing the bottom surface of the glue - making glass assembly 200.

[0041] Four sets of pressing link mechanisms 130 are provided. The four sets of pressing link mechanisms 130 are evenly distributed on two side surfaces at both ends of the receiving seat 114 in the horizontal extension direction. Each pressing link mechanism 130 includes a parallel rod shaft 131, a parallel rod 132, a pressing plate shaft 134, a pressing plate 135, and a guide shaft 137. Operation holes 116 communicating with the receiving holes 115 are provided at the positions of the receiving seat 114 corresponding to the pressing link mechanisms 130. A parallel rod shaft 131 is installed at each of the upper and lower ends of the receiving seat 114 corresponding to the operation holes 116. The parallel rod shaft 131 is parallel to the extension direction of the receiving seat 114 in the horizontal direction. A parallel rod 132 is penetrated on each parallel rod shaft 131. Extension arms 133 extending inwards are provided at both ends of the parallel rod 132. A pressing plate shaft 134 is penetrated between the extension arms 133. The pressing plate 135 is located in the operation hole 116, and a connecting protrusion 136 is provided on the outer side of the pressing plate 135 corresponding to each parallel shaft. The connecting protrusion 136 is penetrated and connected to the corresponding pressing plate shaft 134. A guide shaft 137 extending vertically outwards is connected to the middle of the outer side of the pressing plate 135.

[0042] The power mechanism is connected to each guide shaft 137 to drive the guide shaft 137 to move downwards or upwards synchronously. The guide shaft 137 drives the pressing plate 135 to move downwards or upwards. The parallel rod 132 is restricted by the parallel rod shaft 131 and presses the pressing plate 135 downwards and inwards or releases the pressing plate 135 upwards and outwards through the extension arms 133. And the power mechanism locks the position of the pressing plate 135 to press and clamp the glue - making glass assembly 200 or release the glue - making glass assembly 200.

[0043] Wherein, feet can be provided on the bottom surface of the base 110 to provide support for the whole fixture. The receiving hole 115 of the receiving seat 114 facilitates the taking and placing of the glue - making glass assembly 200, and the lower end of the glue - making glass assembly 200 can pass through the receiving hole 115 and be placed on the surface of the sealing frame assembly 120. A sealing strip 122 is embedded on the surface of the sealing frame assembly 120 corresponding to the glue - making glass assembly 200. One set of pressing link mechanism 130 is provided on each of the two side surfaces at the left and right ends of the glue - making glass assembly 200. Each operation hole 116 extends in the up - down direction of the receiving seat 114.

[0044] In the embodiment of the present application, the extension arm 131 extends in an obliquely upward direction and is connected to the pressing plate shaft 134. It can be understood that the pressing plate shaft 134 is connected to the pressing plate 135 and the parallel rod 132. When the pressing plate 135 moves up and down, the pressing plate shaft 134 drives the parallel rod 132 to move as well. Due to the limitation of the parallel rod shaft 131, the parallel rod 132 can only rotate around the parallel rod shaft 131. Therefore, during the up and down movement of the pressing plate 135, the rotation of the parallel rod 132 causes the extension arm 133 to push the pressing plate 135 to move outward and upward or inward and downward, so that the pressing plate 135 forms a loosening or pressing action on both sides of the gel-making glass assembly 200. Moreover, during the downward pressing process, the gel-making glass assembly 200 is pressed against the sealing strip 122 of the sealing frame assembly 120 by friction to form a seal; during the upward loosening process, the gel-making glass assembly 200 is no longer sealed with the sealing strip 122 and is in a relaxed state as a whole, and the taking-out or inserting operation of the gel-making glass assembly 200 can be performed. Further, the four groups of pressing link mechanisms 130 operate synchronously and symmetrically, with uniform force. And after the pressing plate 135 reaches the preset position, the power mechanism locks the position of the pressing plate 135 to provide stable and reliable pressing and clamping forces.

[0045] The connecting protrusion 136 is provided with a protruding action surface in the middle and recessed guiding surfaces connected to both sides. The action surface and the guiding surfaces are smoothly connected. By the abutting arrangement of the action surface and the guiding surfaces with the outer peripheral surface of the parallel rod 132, the parallel rod 132 can be guided and limited.

[0046] The embodiment of the present application provides a link mechanism gel preparation fixture 100, including a machine base, a sealing frame assembly 120, a pressing link mechanism 130, and a power mechanism. When in use, first, place the gel-making glass assembly 200 in the receiving seat 114 on the machine base, and the bottom surface of the gel-making glass assembly 200 abuts against the sealing frame assembly 120; second, operate the guiding shaft 137 to move downward through the power mechanism. The guiding shaft 137 drives the pressing plate 135 to move downward, and the extension arm 133 of the parallel rod 132 drives the pressing plate shaft 134 to move downward and inward accordingly. Further, the pressing plate 135 presses the gel-making glass assembly 200 downward and inward, so that the side surface of the gel-making glass assembly 200 is pressed, and at the same time the bottom surface is sealed by the sealing frame assembly 120. Lock the power mechanism to keep the gel-making glass assembly 200 in the current state; then, the gel preparation work can be carried out; finally, after the gel preparation is completed, operate the guiding shaft 137 to move upward through the power mechanism. The guiding shaft 137 drives the pressing plate 135 to move upward, and the extension arm 133 of the parallel rod 132 drives the pressing plate shaft 134 to move upward and outward accordingly. Further, the pressing plate 135 loosens the gel-making glass assembly 200 upward and outward, and then the gel-making glass assembly 200 can be taken out.

[0047] In the embodiment of the present application, with the active operation of the power mechanism, the pressing link mechanism 130 is operated once, and the clamping action in the horizontal direction and the pressing action in the vertical direction of the glue-making glass assembly 200 can be realized simultaneously, forming an effective seal on the side and bottom surfaces of the glue-making glass assembly 200, and avoiding the problem of unstable acting force caused by two operations. Moreover, after the position of the pressing plate 135 is determined, its position can be locked, making the clamping force reliable and stable. Even in case of wear during long-term use, the gel preparation can still be stably carried out, avoiding the phenomenon of liquid leakage, facilitating the operation of scientific research and production personnel, and improving the success rate of the glue-making operation.

[0048] In an implementable embodiment, as Figure 1 、 Figure 2 and Figure 4 shown, the power mechanism includes two power link mechanisms 140. One set of power link mechanisms 140 is provided at each of the two ends of the horizontal extension direction of the receiving seat 114, and each power link mechanism 140 is used to drive the two pressing link mechanisms 130 at the same end of the receiving seat 114.

[0049] In this way, both the pressing link mechanism 130 and the power link mechanism 140 are symmetrically arranged, and the power link mechanism 140 can be symmetrically operated from both ends and both sides of the receiving seat 114, facilitating the application of force, and the pressing link mechanisms 130 at the same end move synchronously, and the glue-making glass assembly 200 is uniformly stressed.

[0050] In an implementable embodiment, as Figure 1 、 Figure 2 、 Figure 4 and Figure 5 shown, the power link mechanism 140 includes a wrench shaft 141, a wrench 142 and two guide arms 143. The wrench shaft 141 is connected to the middle part of the side surface of the receiving seat 114, and the extending direction of the wrench shaft 141 is perpendicular to the extending direction of the receiving seat 114. The wrench 142 is sleeved on the middle part of the wrench shaft 141, the wrench 142 extends upward, and the upper part of the wrench 142 is connected with a driving member for driving the wrench 142 to move horizontally closer to or away from the receiving seat 114. The two guide arms 143 are sleeved on both sides of the wrench shaft 141 and are connected to the wrench 142. Both of the two guide arms 143 extend towards the center of the receiving seat 114, and guide holes 144 for passing through the guide shaft 137 are formed on both of the two guide arms 143. The guide holes 144 are strip-shaped holes.

[0051] In this way, using the lever principle, through the horizontal swing of the upper wrench 142, the up-and-down swing of the lower guide arms 143 is formed, and then transmitted to the pressing link mechanism 130, so that the guide shaft 137 moves up and down, and finally the clamping action in the horizontal direction and the pressing action in the vertical direction of the glue-making glass assembly 200 are formed, thereby sealing the glue-making glass assembly 200 in two directions.

[0052] In an implementable embodiment, as Figure 5 shown, the driving member includes a bolt 145, a nut 146 and a return spring (not shown). One end of the bolt 145 is fixedly connected to a position of the receiving seat 114 corresponding to the upper part of the wrench 142, and the other end of the bolt 145 passes through a through hole preset in the upper part of the wrench 142. The nut 146 is located on the side of the wrench 142 away from the receiving seat 114 and is threadedly connected to the bolt 145. The return spring is sleeved around the outer periphery of the bolt 145 and abuts between the wrench 142 and the receiving seat 114.

[0053] In this way, since the bolt 145 is fixed on the receiving seat 114, by rotating the nuts 146 on both sides, the nuts 146 on both sides drive the upper parts of the wrenches 142 on both sides to move synchronously inward and outward in the horizontal direction, and then push the wrenches 142 and the guide arms 143 to rotate around the wrench shaft 141, so that the guide arms 143 and the guide holes 144 on the guide arms 143 move synchronously in the up and down direction.

[0054] The upward movement transmitted through the guide arm 143 and its guide hole 144 is converted by the pressing link mechanism 130 into a clamping and loosening movement of the glue-making glass assembly 200, and a self-locking can be formed during clamping to prevent the loosening between the glue-making glass assemblies 200. In this way, the side surfaces on both sides of the glue-making glass assembly 200 are tightly pressed together, and the lower part is tightly pressed against the sealing strip 122 in the sealing frame assembly 120, so as to form a leak-proof sealing space in the middle of the glue-making glass assembly 200 for gel preparation. Similarly, the downward movement transmitted through the guide arm 143 and its guide hole 144 is the relaxation movement of the glue-making glass assembly 200.

[0055] In an implementable embodiment, as Figure 1 , Figure 2 and Figure 4 shown, one end of the guide arm 143 connected to the wrench 142 extends in the up and down direction and is fixed to the position of the wrench 142 away from the receiving seat 114 by screws. One end of the guide arm 143 connected to the guide shaft 137 extends in the horizontal direction, and the guide hole 144 extends in the horizontal direction.

[0056] In this way, during the rotation of the outer end of the guide arm 143 around the wrench shaft 141 with the wrench 142, the inner end of the guide arm 143 will not interfere with the parallel rod 132, and the horizontally extending guide hole 144 can not only adapt to the up and down movement of the pressing plate 135, but also has a moving space in the left and right directions.

[0057] In an implementable embodiment, as Figure 3 shown, an anti-slip gasket 138 is embedded on the side of the pressing plate 135 close to the receiving seat 114.

[0058] In this way, the anti-slip gasket 138 is used to increase the friction between the pressing plate 135 and the rubber-making glass assembly 200, and improve the stability of the clamping force.

[0059] In an implementable embodiment, as Figure 1 、 Figure 2 and Figure 4 shown, an observation hole 117 for facilitating the observation of the rubber-making situation is provided at the middle position of the accommodation seat 114.

[0060] In this way, it is convenient for scientific research and production personnel to observe and record during the rubber-making process.

[0061] In an implementable embodiment, as Figures 1-4 shown, two pedestals 112 are provided on the base 110, and the accommodation seat 114 is connected above the two pedestals 112.

[0062] A limiting plate 113 parallel to the accommodation seat 114 is connected to one side of the two pedestals 112, and a guiding slideway 111 is provided between the other sides of the two pedestals 112. The sealing frame assembly 120 is detachably fixed to the lower part of the accommodation seat 114 along the guiding slideway 111.

[0063] In this way, the accommodation seat 114 can be stably fixed on the base 110, and a space for the sealing frame assembly 120 to enter and exit is reserved between the accommodation seat 114 and the base 110. The sealing frame assembly 120 slides into the gap between the base 110 and the accommodation seat 114 through the guiding slideway 111 and is limited by the limiting plate 113.

[0064] In an implementable embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the sealing frame assembly 120 includes a sealing box 121 and a sealing strip 122. The upper part of the sealing box 121 is open and is embedded with the sealing strip 122. A first magnet is embedded in the lower part of the sealing box 121, and a second magnet is embedded in the guiding slideway 111 at a position corresponding to the lower part of the accommodation seat 114. The first magnet and the second magnet are magnetically attracted.

[0065] Among them, in some embodiments, the left and right sides of the sealing box 121 can also be open, which is convenient for the taking and placing of the sealing strip 122.

[0066] The sealing box 121 is magnetically attracted to the base 110, which is convenient for the detachable positioning and installation of the sealing frame assembly 120 and the base 110. Of course, the sealing frame assembly 120 and the base 110 can also be detachably connected by other means, such as snap connection, screw connection, etc.

[0067] In an implementable embodiment, as Figure 1 shown, a handle 123 for facilitating operation is provided on the side of the sealing box 121 away from the limiting plate 113.

[0068] In this way, the handle 123 can be pulled in and out of the sealing box 121 through the guiding slideway 111, which is convenient for operation.
