[0049] To make the objectives, technical solutions and advantages of the present utility model clearer, the following will clearly and completely describe the technical solutions of the present utility model in combination with specific embodiments of the present utility model and the corresponding drawings. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts belong to the scope of protection of the present utility model.

[0050] A multi-position electrophoresis tank body according to an embodiment of the present application, as Figures 1 - 6 shown, it includes: a tank body main body 1, the tank body main body 1 has a cavity, and at least two electrophoresis positions 12 adapted to the gel rack assembly 2 are formed in the cavity. A convex portion 13 is provided between two adjacent electrophoresis positions 12. The convex portion 13 is detachably connected in the cavity, or the convex portion 13 is integrally formed with the cavity, so that an independent space is formed between two adjacent electrophoresis positions 12; an observation space is formed between the outside of the convex portion 13 and the tank body main body 1, and the observation space is in a hollowed-out shape, which is convenient for directly observing the electrophoresis state of the two inner gel plates 24, improving the experimental efficiency; in this embodiment, the convex portion 13 has a first preset height, and the first preset height is not lower than the position of the anode outlet 241 of the gel plate 24 of the gel rack assembly 2; the first preset height is not higher than the top end of the gel plate 24 of the gel rack assembly 2. If the height is too high, materials will be wasted.

[0051] Designed in this way, firstly, it ensures that the gel plate 24 in the middle position of the gel rack assembly 2 can be directly observed. Secondly, a convex portion 13 is added between two adjacent electrophoresis positions 12. When using electrophoresis on one side, only the buffer solution needs to be added on the corresponding side, without filling the buffer solution in both electrophoresis positions 12, which can greatly save the buffer solution. Refrigerating substances such as ice cubes can be added to the electrophoresis position 12 on the other side, which can reduce the temperature of the buffer solution, facilitate heat dissipation, and improve the electrophoresis quality. It should be noted that, for the convenience of observation, the multi-position electrophoresis tank body is made of a light-colored material as a whole, such as a transparent material.

[0052] In addition, the top of the convex portion 13 is in a platform shape, which is convenient for placing heat-dissipating substances such as ice cubes.

[0053] In one embodiment, as Figure 5 shown, a preset angle A is formed between two adjacent electrophoresis positions 12, and the convex portion 13 is located in the area where the preset angle A is located. The preset angle A is 5-90 degrees; preferably, the preset angle A is 5 degrees, 10 degrees, 30 degrees, 40 degrees or 50 degrees. On the premise of meeting the functions, the best direct observation of the gel plate 24 in the middle position of the gel rack assembly 2 can be achieved.

[0054] In one embodiment, as Figures 1 - 2 and Figure 6As shown, a recessed groove 14 is formed on one side of the convex portion 13. There is a preset distance between the bottom of the recessed groove 14 and the bottom of the cavity, and the preset distance is not lower than the position of the anodic outlet 241 of the rubber plate 24 of the rubber rack assembly 2. It should be noted that the rubber plate 24 and the anodic outlet 241 are prior arts. For example, the glass slide assembly and the lateral opening groove disclosed in the publication number CN108490059A, the glass slide assembly corresponds to the rubber plate 24, and the lateral opening groove corresponds to the anodic outlet 241. Designed in this way, to ensure that the positive conductive part of the rubber rack assembly 2 is in conduction with the buffer liquid in the electrophoresis position 12, that is, the buffer liquid here should ensure that the positive conductive part can be covered. While reducing the buffer liquid in two adjacent electrophoresis positions 12, it is also convenient for the buffer liquid in two adjacent electrophoresis positions 12 to be filled in time. This situation is used when electrophoresis work is carried out in two adjacent electrophoresis positions 12; it can also be used as a heat dissipation space to facilitate heat dissipation during electrophoresis work.

[0055] In one embodiment, as Figures 1 - 2 and Figure 6 shown, the left and right side walls of the cavity are respectively recessed inward to form protruding portions 15, and the protruding portions 15 are close to the rubber plate 24 of the corresponding rubber rack assembly 2; the space protruding from the protruding portions 15 can also play a role in reducing the buffer liquid. At the same time, the outside of the protruding portions 15 can also be used as a handling and lifting part during handling; in addition, the space protruding from the protruding portions 15 is closer to the position of the rubber plate 24 of the rubber rack assembly 2, so that the experimenter can clearly see the real-time electrophoresis process and electrophoresis results of the rubber plate 24. In this embodiment, the left and right sides of the cavity are the two sides parallel to the rubber plate 24 of the rubber rack assembly 2 arranged in the electrophoresis position 12, as Figures 7 - 8 shown.

[0056] Furthermore, the side wall of the convex portion 13 is arranged parallel to the rubber plate 24 of the rubber rack assembly 2 to achieve a better observation effect. It should be noted that, for the convenience of processing, in this embodiment, the convex portion 13, the protruding portion 15 and the groove body 1 are integrally formed and have the same thickness.

[0057] In one embodiment, as Figures 1 - 2 shown, bearing platforms 16 are respectively formed on the front and rear sides of the cavity. During use, the bracket of the rubber rack assembly 2 is matched with the bearing platforms 16. In this embodiment, the front and rear sides of the cavity are the two sides perpendicular to the aforementioned rubber plate 24, as Figures 7 - 8 shown.

[0058] In one embodiment, as Figures 1 - 3 shown, a limiting unit 17 is formed on the bearing platform 16 of the cavity. The limiting unit 17 is matched with the rubber rack assembly 2, so that when the rubber rack assembly 2 works in the corresponding electrophoresis position 12, it is not easy to shift.

[0059] Specifically, as Figure 2 and Figure 3As shown in the figure, the limiting unit 17 includes a limiting body 171 connected to the tank body 1. The bottom of the limiting body 171 is connected to the bearing platform 16, and a guide block 172 extends from one side. The bottom of the guide block 172 is integrated with the bearing platform 16. The guide block 172 is inclined to facilitate the sliding of the bracket 21 of the rubber rack assembly 2 onto the bearing platform 16. On the top of the limiting body 171, a limiting block 174 is formed on the side opposite to the guide block 172. A limiting groove is formed between the limiting block 174 and the limiting body 171 for limiting the bracket 21 of the rubber rack assembly 2. The mounting groove 211 on the bracket 21 of the rubber rack assembly 2 enters from the top member formed by the limiting body 171 and the limiting block 174. Under the combined action of the guide block 172 and the limiting groove, the bracket 21 of the rubber rack assembly 2 is limited, achieving the limiting effect and ensuring the stability of the rubber rack assembly 2 during operation. The length of the guide block 172 is greater than the length of the limiting block 174. The length of the mounting groove 211 is greater than the length between the limiting body 171 and the limiting block 174, and the length of the mounting groove 211 is the same as the length between the limiting body 171 and the guide block 172. When taking it out, it slides out from the guide block 172 and finally is taken out from between the limiting body 171 and the limiting block 174. With such a design, the rubber rack assembly 2 is limited in all directions (up, down, left, and right), and the effect is good.

[0060] An electrophoresis tank according to an embodiment of the present application, as Figures 8 - 12 shown, includes: the multi-gel electrophoresis tank body as described above and at least one rubber rack assembly 2. The rubber rack assembly 2 is disposed in the corresponding electrophoresis position 12. It should be noted that the rubber rack assembly 2 includes a bracket 21. Corresponding rubber plates 24 are respectively connected to both sides of the bracket 21. A preset space is formed between the bracket 21 and the rubber plates 24 for filling buffer solution. A positive electrode 22 and a negative electrode 23 are connected to the bracket 21 for respectively connecting to the positive and negative poles of the power supply. A positive electrode conducting member is connected to the positive electrode 22, and the other end of the positive electrode conducting member is located at the bottom of the bracket 21. The other end of the positive electrode conducting member is used for conducting electricity with the buffer solution in the electrophoresis position 12. A negative electrode conducting member is connected to the negative electrode 23, and the other end of the negative electrode conducting member conducts electricity with the buffer solution in the liquid storage cavity formed by the rubber rack assembly 2 and the rubber plates 24.

[0061] The positive electrode 22 and the negative electrode 23 form an electric field between the buffer solution in the liquid storage cavity formed by the rubber rack assembly 2 and the rubber plates 24 and the buffer solution in the electrophoresis position 12 through the negative electrode conducting member and the positive electrode conducting member, promoting the movement of charged ions in the buffer solution in the gel to complete the electrophoresis experiment. This is the prior art, such as the working principle of the rubber rack assembly disclosed in the publication number CN108490059A, which will not be elaborated here.

[0062] In one embodiment, as Figure 7 and Figure 9As shown, it also includes a slot cover 3, which is connected to the slot body 1, and the slot cover 3 covers the cavity inside; there is a preset interval between the top of the raised portion 13 and the slot cover 3, and the preset interval can increase the heat dissipation space; the top of the raised portion 13 is platform-shaped and heat dissipation materials, such as ice cubes, can be stored between the preset interval; one or more limiting connection parts 31 are provided on the slot cover 3, and the limiting connection parts 31 are long strip holes, and a limiting guide part 32 that matches the limiting connection part 31 is formed on the slot body 1, and the limiting guide part 32 is a guide protrusion, and in order to facilitate guiding, the end of the guide protrusion is chamfered.

[0063] In one embodiment, if Figure 9 As shown, a gripping portion 33 is formed on the side of the slot cover 3 for easy gripping.

[0064] In one embodiment, if Figure 9 As shown, the slot cover 3 is provided with a clearance hole 34 for the electrode of the glue rack assembly 2 to make way.

[0065] When the tank cover 3 is connected to the tank body of the multi-position electrophoresis tank, the positive electrode 22 and the negative electrode 23 match the corresponding clearance holes 34 .

[0066] It should be noted that, according to the requirements of the actual experiment, the positive electrode of each group of the glue rack assembly is connected to the positive electrode of the power supply, and the negative electrode of each group of the glue rack assembly is connected to the negative electrode of the power supply;

[0067] Or the positive electrodes of multiple groups of gel rack components are connected in series and then connected to the positive electrode of the power supply, and the negative electrodes of multiple groups of gel rack components are connected in series and then connected to the power supply; to realize multiple groups of electrophoresis experiments, the connection of positive electrodes and negative electrodes is a prior art and will not be repeated here, such as Figures 13 - 15 shown.
