Description

Technical Field

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

[0002] The phenomenon that charged particles move towards the electrode with the opposite electric charge 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 different 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 component). During preparation, a gel preparation fixture is used to align and correct 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 component. Gel liquid is poured at the open top, and the gel can be obtained after the gel liquid cools.

[0004] However, the gel preparation fixtures in the related art generally can only adapt to a gel - making glass sheet component of one thickness. When gel - making glass sheet components of multiple thicknesses are required, the fixture needs to be replaced, which brings great inconvenience to experimental work. Moreover, the gel preparation fixtures in the related art generally use passive cams or passive inclined plates, relying on the elastic force and friction of the fixture to self - lock to achieve clamping between the gel - making glass sheet components. Due to insufficient elastic force of the fixture and unstable elastic force of the fixture, there are often liquid leakage phenomena caused by the failure to tightly clamp the gel - making glass sheet components. Utility Model Content

[0042] To make the purpose, 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, and should not be construed as a limitation to the present application.

[0043] The following will combine Figures 1-6 to describe the double - slice gel preparation fixture 100 provided by the embodiment of the present application.

[0044] The embodiment of the present application provides a double - slice gel preparation fixture 100, as Figures 1-5 shown, including a base 110, a main frame 120, a sealing assembly 130, a wedge - block locking assembly 140 and a locking component 150.

[0045] The main frame 120 is mounted on the base 110 through an elastic support assembly. The main frame 120 includes two receiving seats 122 and two side plates 126. The two receiving seats 122 are symmetrically arranged front and back, and each of the two receiving seats 122 is provided with a long receiving hole 123 that penetrates up and down for placing the glue-making glass assembly 200. The two side plates 126 are symmetrically arranged left and right, and each side plate 126 is connected between the two receiving seats 122 at the corresponding end.

[0046] There are two sealing assemblies 130, and the two sealing assemblies 130 are respectively detachably connected to the lower part of the base 110 corresponding to the receiving seats 122 for sealing the bottom surface of the glue-making glass assembly 200.

[0047] The wedge locking assembly 140 is installed between the two receiving seats 122 and includes a pressing plate 141, a horizontal shaft 144, side sliders 145, an intermediate slider 147 and a power member. A pressing plate 141 is arranged in parallel on the inner side of each receiving seat 122. A pressing protrusion 142 is arranged on one side of each pressing plate 141 close to the corresponding receiving seat 122, and an operation hole 125 communicating with the receiving hole 123 is formed in the receiving seat 122 corresponding to the pressing protrusion 142. A number of horizontal shafts 144 are connected between the two receiving seats 122 and penetrate through each pressing plate 141. An intermediate slider 147 is connected to the middle position of the inner side of each pressing plate 141, and the inner surface of the side slider 145 is an inclined surface extending inwards and downwards. The intermediate slider 147 is located between the two side sliders 145, and the front and rear two side surfaces of the intermediate slider 147 are slidably connected to the side surfaces of the corresponding side sliders 145. The power member is connected to the intermediate slider 147 to drive the intermediate slider 147 to move downwards or upwards, push the side sliders 145 to drive the pressing plate 141 to move towards or away from the receiving seat 122, and the power member locks the position of the pressing plate 141. Furthermore, the pressing protrusion 142 presses or releases the glue-making glass assembly 200 through the operation hole 125.

[0048] There are two locking components 150, and the two locking components 150 are symmetrically arranged on the outer side of the side plate 126 for overcoming the resistance of the elastic support assembly and locking the relative position between the main frame 120 and the base 110.

[0049] Wherein, feet 112 can be arranged on the bottom surface of the base 110 to provide support for the whole fixture. The main frame 120 maintains a gap with the base 110 through the elastic support assembly, which is convenient for the positioning and installation of the sealing assembly 130. The receiving hole 123 of the receiving seat 122 is convenient for 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 123 and be placed on the surface of the sealing assembly 130. A sealing strip 132 is embedded on the surface of the sealing assembly 130 corresponding to the glue-making glass assembly 200.

[0050] A pressing plate 141 is arranged on the inner side of each accommodating seat 122. Thus, two pressing plates 141 are arranged between the two accommodating seats 122, and a horizontal shaft 144 can penetrate through the four corners of the two pressing plates 141. The horizontal shaft 144 is slidably connected to the pressing plate 141 and has a guiding effect on the movement of the pressing plate 141.

[0051] It can be understood that the front and rear side surfaces of the middle slider 147 are both in sliding fit with the inner side surfaces of the edge sliders 145. The front and rear side surfaces of the middle slider 147 are inclined downward toward the center, and the inner side surfaces of the edge sliders 145 are inclined downward and inward. When the middle slider 147 moves downward, it can push the edge sliders 145 to move outward, thereby driving the pressing plate 141 to press the glue-making glass assembly 200. Similarly, when the middle slider 147 moves upward, it can push the edge sliders 145 to move inward, thereby driving the pressing plate 141 to release the glue-making glass assembly 200. According to the displacement of the up and down movement of the middle slider 147, the displacement of the outward and inward movement of the edge sliders 145 can be controlled, so as to adapt to the pressing of glue-making glass assemblies 200 with different thicknesses. When the locking power component is locked, the position of the pressing plate 141 is relatively determined, and the glue-making glass assembly 200 is under the action of a stable clamping force, avoiding the phenomenon of liquid leakage.

[0052] Due to the symmetrical arrangement of the two edge sliders 145 and the accommodating seats 122, two groups of glue-making glass assemblies 200 can be clamped simultaneously, realizing the simultaneous preparation of double-sided gels. In some embodiments, only the preparation of one-sided gel is allowed. It should be noted that to ensure the balance of forces on both sides, a glue-making glass assembly 200 or a substitute should also be placed in the accommodating seat 122 where no gel is prepared.

[0053] Through experiments, the embodiments of the present application can be compatible with the thicknesses of any mainstream glue-making glass assemblies 200 within the range of 4.75 mm - 5.5 mm. Even if the thickness error of the glue-making glass assembly 200 is large, gels with any thickness within the range of 0.75 - 1.5 mm can still be made.

[0054] An embodiment of the present application provides a double - sheet gel preparation fixture 100, which includes a base 110, a main frame 120, a sealing component 130, a wedge - block locking component 140, and a locking component 150. When in use, first, two sets of gel - making glass components 200 are respectively placed in the receiving holes 123 of two receiving seats 122, so that the bottom surface of the gel - making glass component 200 abuts against the corresponding sealing component 130; secondly, the power component is operated to press the middle slider 147 downward, the middle slider 147 pushes two side sliders 145 to move outward, the side sliders 145 drive the pressing plate 141 to move towards the gel - making glass component 200, and then the pressing protrusion 142 presses the gel - making glass component 200 tightly. When the locking force meeting the set thickness requirement is reached, the power component is locked to keep the gel - making glass component 200 in the current state; then, the locking component 150 is operated to lock and press the main frame 120 on the sealing component 130, so that the bottom surface of the gel - making glass component 200 is sealed; after that, the gel preparation work can be carried out; finally, after the gel preparation is completed, the power component is operated to loosen the middle slider 147 upward, the two side sliders 145 move inward accordingly, the side sliders 145 drive the pressing plate 141 to move away from the gel - making glass component 200, and then the pressing protrusion 142 loosens the gel - making glass component 200. Moreover, the locking component 150 is operated to make the main frame 120 disengage from the sealing with the sealing component 130 upward, and then the gel - making glass component 200 can be taken out.

[0055] By means of the operation of the power component in the embodiment of the present application, the wedge - block locking component 140 can clamp two gel - making glass components 200 with a single operation, and two gels can be prepared simultaneously. Moreover, by pressing and self - locking the gel - making glass component 200 through the wedge - block locking component 140, the thickness range of the mainstream gel - making glass component 200 can be compatible, the preparation of gels within the mainstream thickness range can be realized, and the active fixture design requirements of stable gel preparation without liquid leakage even in case of wear and other situations during long - term use are met.

[0056] In an implementable embodiment, as Figure 4 and Figure 5 shown, the power component includes a bolt 160 and a nut 161. The bolt 160 passes through the middle slider 147 in the vertical direction, and the lower end of the bolt 160 is fixedly connected to the main frame 120. The nut 161 is threadedly connected to the upper end of the bolt 160 and abuts against the middle slider 147.

[0057] Wherein, a through - hole is opened at the center of the middle slider 147, and the bolt 160 passes through the through - hole. The nut 161 is pressed on the upper surface of the middle slider 147, and a wrench convenient for operation can be connected to the nut 161.

[0058] In this way, the bolt 160 remains relatively stationary. When the nut 161 is rotated, the nut 161 rotates up and down along the bolt 160. As a result, the intermediate slider 147 moves up and down accordingly, and the intermediate slider 147 pushes the edge slider 145 to move inwards or outwards, ultimately realizing the loosening or clamping action of the sealant glass assembly 200. Moreover, the threaded connection between the bolt 160 and the nut 161 facilitates the design of controlling the locking force. Exemplarily, when the nut 161 encounters resistance during the tightening process, it can be considered that the pressing protrusion 142 abuts against the sealant glass assembly 200. Furthermore, it can be designed that the nut 161 continues to rotate a set number of turns or an angle to provide a locking force that meets the set requirements.

[0059] In an implementable embodiment, as Figures 4-6 shown, a fixing plate 121 is connected between the two side plates 126. The fixing plate 121 is spaced from the adjacent pressing plate 141, and the lower end of the bolt 160 is fixed to the fixing plate 121.

[0060] In this way, the fixing plate 121 can not only improve the stability of the main frame 120, but also have a limiting effect on the pressing plate 141. At the same time, the fixing plate 121 also provides a fixed installation position for the bolt 160.

[0061] In an implementable embodiment, as Figures 1-3 shown, an elastic limiting piece 146 that bends towards the intermediate slider 147 is provided at the top of the edge slider 145, and the elastic limiting piece 146 abuts against the side surface of the nut 161.

[0062] In this way, the elastic limiting piece 146 can have a limiting effect on the nut 161, improve the friction between the nut 161 and the intermediate slider 147, and improve the stability of the pressing force.

[0063] In an implementable embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the latch assembly 150 includes a support 111, a locking latch 151 and a locking hook 152. The support 111 is arranged on the base 110 outside the side plate 126. The locking hook 152 is fixed to the side plate 126. The locking latch 151 is hinged to the support 111 and is provided with a hanging ring for hook connection with the locking hook 152.

[0064] The hanging ring is hooked to the locking hook 152. When the locking latch 151 is rotated downwards to be pressed, the hanging ring tightens the locking hook 152, causing the side plate 126 to overcome the elastic force of the elastic support assembly and remain relatively fixed to the support 111. When the locking latch 151 is rotated upwards to be loosened, the hanging ring and the locking hook 152 are in a loosened state, causing the side plate 126 to be separated from the support 111 relatively and be supported by the elastic support assembly.

[0065] In this way, when the gel-making glass component 200 is clamped in the horizontal direction, the main frame 120 is driven by the buckle component 150 to move downward and be locked. The bottom surface of the gel-making glass component 200 is sealed by the sealing strip 132 of the sealing component 130, and then the gel preparation work can be carried out. When the gel preparation is completed, the main frame 120 is driven by the buckle component 150 to move upward, and the bottom surface of the gel-making glass component 200 is separated from the sealing of the sealing strip 132. Then, the wedge locking component 140 is operated to release the clamping of the gel-making glass component 200, and the gel-making glass component 200 can be removed.

[0066] Of course, in some embodiments, the wedge locking component 140 can also be operated first to release the clamping of the gel-making glass component 200, and then the relative fixation of the main frame 120 and the support 111 by the buckle component 150 can be released.

[0067] In other embodiments, other structures with the same function, such as elbow clamps, can also be used to realize the relative fixation and separation of the main frame 120 and the base 110.

[0068] In an implementable embodiment, as Figure 1 、 Figure 3 and Figure 4 shown, the elastic support component includes a vertical pin 170 and a spring (not shown). The vertical pin 170 is installed on the base 110, and the upper end of the vertical pin 170 has a limiting platform. The main frame 120 is provided with a collar 127, and the collar 127 is sleeved on the vertical pin 170 and is limited below the limiting platform. The spring is sleeved on the outer periphery of the vertical pin 170 and abuts between the collar 127 and the base 110.

[0069] Among them, four vertical pins 170 can be evenly distributed between the main frame 120 and the base 110. When the buckle component 150 is pulled downward, the main frame 120 can move downward perpendicular to the base 110 under the guidance of the vertical pin 170, and the main frame 120 overcomes the elastic force of the spring to lock the relative position with the base 110. When the buckle component 150 is pulled upward, under the elastic reset force of the spring, the main frame 120 can move upward perpendicular to the base 110 under the guidance of the vertical pin 170 and be supported by the spring.

[0070] In an implementable embodiment, a slide bar extending along the sliding direction is provided on the intermediate slider 147, and a sliding groove extending along the sliding direction is provided on the edge slider 145, and the slide bar and the sliding groove are matched and installed.

[0071] Alternatively, a sliding groove extending along the sliding direction is provided on the intermediate slider 147, and a slide bar extending along the sliding direction is provided on the edge slider 145, and the slide bar and the sliding groove are matched and installed.

[0072] In this way, with the cooperation of the sliding bar and the sliding groove, the middle slider 147 and the edge slider 145 can better achieve the driving force along the inclined plane and avoid misaligned movement.

[0073] In an implementable embodiment, as Figure 1 and Figure 5 shown, pressing protrusions 142 are provided at both the left and right ends of each pressing plate 141, and two operation holes 125 are correspondingly provided at both the left and right ends of each receiving seat 122.

[0074] In this way, the pressing plate 141 can apply forces symmetrically to the left and right on the rubber-making glass assembly 200, and the force is balanced.

[0075] The pressing protrusion 142 has a surface parallel to the rubber-making glass assembly 200, and the surface of the pressing protrusion 142 is grooved and a non-slip gasket 143 is embedded therein.

[0076] In this way, the non-slip gasket 143 is used to increase the friction between the pressing plate 141 and the rubber-making glass assembly 200, and the stability of the clamping force is improved.

[0077] In an implementable embodiment, as Figure 1 and Figure 5 shown, the sealing assembly 130 is installed in a preset limiting groove of the base 110. The sealing assembly 130 includes a sealing box 131 with an open upper part, and a sealing strip 132 embedded in the sealing box 131.

[0078] Among them, in some embodiments, the left and right sides of the sealing box 131 can also be provided with openings for the convenience of taking and placing the sealing strip 132.

[0079] The sealing box 131 and the base 110 can be connected by screws, snap connections or magnetic attraction, which is convenient for the detachable positioning and installation of the sealing assembly 130 and the base 110.

[0080] In an implementable embodiment, as Figure 1 、 Figure 5 and Figure 6 shown, an observation hole 124 for facilitating the observation of the rubber-making situation is opened in the middle of the receiving seat 122.

[0081] In this way, it is convenient for scientific research and production personnel to observe and record during the rubber-making process.

[0082] It should be noted that unless otherwise clearly specified and limited, in the description of this application, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, or an indirect connection through an intermediate medium. It can be the internal communication of two components or the interaction relationship between two components. For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific situations.

[0083] The orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings. It is only for the convenience of describing the present application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation.
