Description

Technical Field

[0001] The utility model relates to the technical field of electrophoresis apparatuses, and specifically relates to a conductive wire installation assembly for an electrophoresis apparatus. Background Technique

[0002] An electrophoresis apparatus is an instrument for realizing electrophoresis analysis, generally composed of a power supply, an electrophoresis tank, a detection unit, etc. Electrophoresis refers to the movement of charged particles in an electric field. Different substances have different charges and molecular weights, so they move at different speeds in the electric field. Based on this, qualitative or quantitative analysis of different substances can be carried out.

[0003] When using an electrophoresis apparatus to conduct an electrophoresis experiment, a conductive wire needs to be connected and installed to the electrophoresis tank to form a circuit and apply an electric field. In the connection of the electrophoresis apparatus, usually, the plug of the conductive wire is inserted and installed in the electrophoresis tank, making it more convenient and convenient to use. However, during long-term use, the conductive wire may become loose from the electrophoresis tank, resulting in the loosening or displacement of the conductive wire, which may cause uneven distribution of the electric field, leading to a decrease or inconsistency in the separation effect. Due to the uneven distribution of the electric field, the conditions of each experiment will vary, making it difficult to repeat and compare the experimental results.

[0004] Therefore, those skilled in the art have provided a conductive wire installation assembly for an electrophoresis apparatus to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the utility model is to provide a conductive wire installation assembly for an electrophoresis apparatus to solve the problems raised in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A conductive wire installation assembly for an electrophoresis apparatus includes an electrophoresis apparatus body and a conductive wire. Two groups of limit posts are arranged on the surface of the electrophoresis apparatus body. Slots are formed on the surface of the limit posts. Positive and negative electrode posts are arranged on the surface of the electrophoresis apparatus body, and the electrode posts extend outward through the limit posts. One end of the conductive wire is fixedly connected with a plug. The conductive wire is movably inserted into the slot through the plug. When the plug is inserted into the slot, the conductive wire is electrically connected to the electrode post. A limiting mechanism for limiting the plug is arranged on the surface of the limit post.

[0008] As a further solution of the utility model: The limiting mechanism includes a fixing piece, a limiting groove, an annular groove, an anti-slip rubber ring, a pressing block, a spring cavity, a return spring, a slot, a ball groove and a limiting ball. The fixing piece is slidably connected to the surface of the limit post. The inner side wall of the fixing piece is fixedly connected with the pressing block. A spring cavity is formed between the pressing block and the limit post. The inner side wall of the spring cavity is provided with a return spring.

[0009] As a further solution of the utility model: one end of the limiting column is provided with uniformly arranged ball grooves, and limiting balls are placed on the inner side walls of the ball grooves.

[0010] As a further solution of the utility model: one end of the plug connector is provided with a limiting groove, and the limiting groove is fitted with the limiting ball.

[0011] As a further solution of the utility model: one end of the plug connector is provided with an annular groove, and an anti-friction rubber ring is fixedly connected to the inner side wall of the annular groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] When connecting the conductive wire, the fixing member can be first toggled. The movement of the fixing member drives the movement of the pressing block. The movement of the pressing block compresses the return spring, so that the return spring is in a compressed state. Then the plug connector is directly inserted. After the plug connector is inserted into the slot, the fixing member is released. After the return spring loses pressure, it returns to the initial state. One end of the return spring moves to drive the movement of the pressing block. The movement of the pressing block abuts against the limiting ball, so that the limiting ball sinks into the limiting groove, thereby completing the limitation of the conductive wire, that is, completing the connection between the pole column and the conductive wire. The connection operation of the conductive wire is simple and convenient, and the connection stability is high. By the anti-friction rubber ring abutting against the inner wall of the slot, the sealing effect is guaranteed, ensuring good sealing performance, which can avoid the problem of water splashing to the connection of the pole column during the taking of the gel, resulting in electric leakage, and it is convenient to install and disassemble the conductive wire. When not in use, the conductive wire can be quickly disassembled, which is convenient for use; Description of the Drawings

Embodiment 1

[0019] Referring to Figures 1-3 , this embodiment provides a conductive wire 5 installation assembly for an electrophoresis instrument, including an electrophoresis instrument body 1 and a conductive wire 5. There are two groups of limit posts 2 arranged on the surface of the electrophoresis instrument body 1. A slot 13 is opened on the surface of the limit post 2. A positive and negative pole post 4 is arranged on the surface of the electrophoresis instrument body 1, and the pole post 4 extends outward through the limit post 2. One end of the conductive wire 5 is fixedly connected with a plug connector 6. The conductive wire 5 is movably inserted into the slot 13 through the plug connector 6. When the plug connector 6 is inserted into the slot 13, the conductive wire 5 is electrically connected to the pole post 4. A limiting mechanism for limiting the plug connector 6 is arranged on the surface of the limit post 2. The limiting mechanism includes a fixing member 3, a limiting groove 7, an annular groove 8, an anti-friction rubber ring 9, a pressing block 10, a spring cavity 11, a return spring 12, a slot 13, a ball groove 14, and a limiting ball 15. A fixing member 3 is slidably connected to the surface of the limit post 2. The inner side wall of the fixing member 3 is fixedly connected with a pressing block 10. A spring cavity 11 is formed between the pressing block 10 and the limit post 2. The inner side wall of the spring cavity 11 is provided with a return spring 12. A uniformly arranged ball groove 14 is opened at one end of the limit post 2. A limiting ball 15 is placed on the inner side wall of the ball groove 14. A limiting groove 7 is opened at one end of the plug connector 6, and the limiting groove 7 is fitted with the limiting ball 15. An annular groove 8 is opened at one end of the plug connector 6, and an anti-friction rubber ring 9 is fixedly connected to the inner side wall of the annular groove 8; when connecting the conductive wire 5, the fixing member 3 can be first toggled. The movement of the fixing member 3 drives the movement of the pressing block 10. The movement of the pressing block 10 compresses the return spring 12, making the return spring 12 in a compressed state. Then, the plug connector 6 is directly inserted. After the plug connector 6 is inserted into the slot 13, the fixing member 3 is released. After the return spring 12 loses pressure, it returns to its initial state. One end of the return spring 12 moves to drive the movement of the pressing block 10. The movement of the pressing block 10 abuts against the limiting ball 15, making the limiting ball 15 sink into the limiting groove 7, thereby completing the limitation of the conductive wire 5, that is, completing the connection between the pole post 4 and the conductive wire 5. The connection of the conductive wire 5 is simple and convenient, and the connection stability is high. By the anti-friction rubber ring 9 abutting against the inner wall of the slot 13, the sealing effect is guaranteed, ensuring good sealing performance, which can avoid the problem of water splashing onto the connection of the pole post 4 when taking the gel, resulting in electric leakage, and it is convenient to install and disassemble the conductive wire 5. When not in use, the conductive wire 5 can be quickly disassembled, which is convenient for use.
