Description

Technical Field

[0001] The utility model relates to the technical field of protein electrophoresis tanks, in particular to a protein electrophoresis tank. Background Art

[0002] The electrophoresis tank is the core part of the gel electrophoresis system. According to the principle of electrophoresis, the gel is placed between two buffer chambers. The electric field connects the two buffer chambers through the gel. The contact between the buffer and the gel can be direct liquid contact or indirect through gel strips or filter paper strips. Tubular gel electrophoresis and vertical plate electrophoresis mostly adopt direct liquid contact.

[0003] The protein electrophoresis tank is used for protein electrolysis experiments. When performing electrolysis, the gel is first placed on both sides of the tank, and the tank and gel are sealed with sealing strips. Then, the raw material to be electrophoresed is added to the slot above the gel, and then the power is turned on to perform the electrophoresis test.

[0004] The gel plates on both sides of the electrophoresis tank are installed by simple plug-in placement, which is prone to loosening, resulting in reduced sealing of the electrophoresis tank; therefore, it does not meet existing needs. In this regard, we propose a protein electrophoresis tank. Utility Model Content

[0005] The utility model aims to provide a protein electrophoresis tank to solve the problem that the gel plates on both sides of the electrophoresis tank proposed in the above background technology are installed by simple plugging and placement, which is easy to become loose, thereby causing the sealing of the electrophoresis tank to decrease.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a protein electrophoresis tank, comprising a collection box, an electrophoresis tank body is placed on the inner side of the collection box, two symmetrical electrophoresis electrodes are fixed on the top of the electrophoresis tank body, the electrophoresis electrodes are connected to a power supply through wires, and rubber plates are inserted on both sides of the electrophoresis tank body, and U-shaped bars are fixed on the outer surfaces of both sides of the electrophoresis tank body, a positioning groove is provided between the U-shaped bar and the electrophoresis tank body, a sealing groove is provided on the inner wall of the positioning groove, a sealing component is installed on the inner side of the positioning groove, the rubber plate is inserted between the U-shaped bar and the electrophoresis tank body and is surrounded by the sealing component, and an extruded sealing sheet is installed between the sealing component and the U-shaped bar.

[0007] Preferably, the sealing component comprises a U-shaped surrounding strip, the U-shaped surrounding strip is attached to the bottom surface and both side surfaces of the rubber plate, and an outer sealing strip and an inner sealing pressure strip are installed on the inner side of the U-shaped surrounding strip.

[0008] Preferably, the outer sealing strip and the inner sealing strip are integrally formed with the U-shaped surrounding strip by injection molding, and the outer sealing strip and the inner sealing strip are divided into two sides of the rubber plate.

[0009] Preferably, a U-shaped sealing clip strip is bonded to the surface of the inner sealing strip facing the electrophoresis tank body, and the U-shaped sealing clip strip is clipped to the inner side of the sealing groove.

[0010] Preferably, the outer sealing strip and the inner sealing strip are both provided with hollow liquid filling chambers, and the liquid filling chambers are filled with pure water.

[0011] Preferably, the spacing between the U-shaped stop bar and the rubber plate, and between the rubber plate and the electrophoresis tank body is less than or equal to the thickness of the outer sealing stop bar and the inner sealing pressure strip.

[0012] Preferably, guide slopes are provided on the inner sides of both ends of the U-shaped guard bar, and the inclination angle of the guide slopes is thirty degrees.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] 1. The utility model inserts the extruded sealing sheet between the U-shaped stop bar and the outer sealing stop bar. When the extruded sealing sheet is inserted between the U-shaped stop bar and the outer sealing stop bar from the top end of the U-shaped stop bar, the extruded sealing sheet will squeeze the outer sealing stop bar toward the rubber plate, and at the same time, the rubber plate will squeeze the inner sealing strip toward the main body of the electrophoresis tank, and the U-shaped sealing clamping strip will be squeezed and deformed in the sealing groove. At this time, the outer sealing stop bar, the inner sealing strip and the U-shaped sealing clamping strip in the force deformation will completely fill the gaps between the extruded sealing sheet and the rubber plate, and between the rubber plate and the main body of the electrophoresis tank, thereby ensuring the overall sealing of the electrophoresis tank when in use;

[0015] 2. The utility model utilizes the pure water filled inside the outer sealing strip and the inner sealing strip to make the outer sealing strip and the inner sealing strip have good elastic deformation ability, so that the outer sealing strip and the inner sealing strip can fill the gap between the rubber plate and the electrophoresis tank body and the extruded sealing sheet while ensuring that the rubber plate will not loosen without external force interference, thereby avoiding the loosening of the rubber plate and the reduction of the electrophoresis tank seal.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] like Figures 1 to 4 As shown, a protein electrophoresis tank comprises a collecting box 1, an electrophoresis tank body 2 is placed inside the collecting box 1, two symmetrical electrophoresis electrodes 6 are fixed on the top of the electrophoresis tank body 2, the electrophoresis electrodes 6 are connected to a power supply through wires, gel plates 5 are inserted on both sides of the electrophoresis tank body 2, U-shaped bars 3 are fixed on the outer surfaces of both sides of the electrophoresis tank body 2, a positioning groove 8 is provided between the U-shaped bar 3 and the electrophoresis tank body 2, a sealing groove 9 is provided on the inner wall of the positioning groove 8, a sealing component 7 is installed inside the positioning groove 8, the gel plate 5 is inserted between the U-shaped bar 3 and the electrophoresis tank body 2 and is surrounded by the sealing component 7, an extruded sealing sheet 4 is installed between the sealing component 7 and the U-shaped bar 3, and the sealing component 7 is used to seal and fill the gap between the gel plate 5 and the electrophoresis tank body 2 and the U-shaped bar 3 to ensure that the liquid inside the electrophoresis tank body 2 will not leak out during electrophoresis.

[0024] The sealing component 7 includes a U-shaped surrounding strip 71, which is attached to the bottom surface and both side surfaces of the rubber plate 5. An outer sealing strip 72 and an inner sealing strip 73 are installed on the inner side of the U-shaped surrounding strip 71. The outer sealing strip 72 and the inner sealing strip 73 are integrally injection molded with the U-shaped surrounding strip 71. The outer sealing strip 72 and the inner sealing strip 73 are divided into two sides of the rubber plate 5. The surface of the inner sealing strip 73 facing the electrophoresis tank body 2 is adhered with a U-shaped sealing clamping strip 74, which is clamped on the inner side of the sealing groove 9. The rubber plate 5 is wrapped on three sides by the U-shaped surrounding strip 71, the outer sealing strip 72 and the inner sealing strip 73, and the gap between the rubber plate 5 and the electrophoresis tank body 2 and the U-shaped strip 3 is filled, and it is ensured that the rubber plate 5 will not loosen during electrophoresis.

[0025] The outer sealing strip 72 and the inner sealing strip 73 are both provided with a hollow liquid filling chamber 75, and the liquid filling chamber 75 is filled with pure water. The liquid filling chamber 75 is filled with pure water so that the outer sealing strip 72 and the inner sealing strip 73 have good elasticity. When squeezed, the outer sealing strip 72 and the inner sealing strip 73 can deform to fit the surface of the extruded object and fill the gap.

[0026] like Figure 1 and Figure 5 As shown, the spacing between the U-shaped baffle 3 and the rubber plate 5, and between the rubber plate 5 and the electrophoresis tank body 2 is less than or equal to the thickness of the outer sealing baffle 72 and the inner sealing bead 73. Guide slopes 10 are provided on the inner sides of both ends of the U-shaped baffle 3. The inclination angle of the guide slope 10 is thirty degrees, ensuring that when the extruded sealing sheet 4 is inserted between the rubber plate 5 and the U-shaped baffle 3, the outer sealing baffle 72 can be squeezed toward the rubber plate 5, and the inner sealing bead 73 can be squeezed toward the electrophoresis tank body 2. At the same time, the U-shaped sealing clamping strip 74 will completely enter the sealing groove 9 and completely fill the internal gap of the sealing groove 9, thereby ensuring the overall sealing of the electrophoresis tank when in use.

[0027] Working principle: First, the staff will clamp the U-shaped sealing clamping strip 74 on the inner side of the sealing groove 9 for compression, and fit the inner sealing strip 73 and the U-shaped surrounding strip 71 to the inner wall of the positioning groove 8. Then, the staff will insert the rubber sheet 5 between the outer sealing strip 72 and the inner sealing strip 73, and push the inserted rubber sheet 5 downward so that the bottom end of the rubber sheet 5 is completely fitted with the U-shaped surrounding strip 71. Next, the staff will insert the extruded sealing sheet 4 between the U-shaped strip 3 and the outer sealing strip 72, and insert the extruded sealing sheet 4 from the top of the U-shaped strip 3 into the U-shaped strip 3 and the outer sealing strip 72. When the sealing strip 72 is between the retaining strips 72, the extruded sealing sheet 4 will squeeze the outer sealing strip 72 toward the rubber plate 5, and the rubber plate 5 will squeeze the inner sealing strip 73 toward the electrophoresis tank body 2, and the U-shaped sealing card strip 74 will be squeezed and deformed in the sealing groove 9. At this time, the outer sealing strip 72, the inner sealing strip 73 and the U-shaped sealing card strip 74 in the force deformation will completely fill the gaps between the extruded sealing sheet 4 and the rubber plate 5, and between the rubber plate 5 and the electrophoresis tank body 2, thereby ensuring the overall sealing of the electrophoresis tank when in use, and the rubber plate 5 will not loosen or shake during the electrophoresis operation.

[0028] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or essential features of the present invention. Therefore, the embodiments should be regarded as exemplary and non-restrictive from any point of view, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present invention.
