Description

Technical Field

[0001] The utility model relates to the field of biological experiment equipment, in particular to an electrophoresis tank for biological experiments. Background Art

[0002] The electrophoresis tank is a commonly used experimental equipment in professional experiments such as biochemistry, molecular biology, and genetic engineering. It is an important part of the gel electrophoresis system and is used for experimental operations such as separation and identification of biological molecules such as amino acids, proteins, and DNA. During the experiment, the biological molecules are added to the comb-tooth spotting holes on one side of the gel, and the gel is placed between the buffer chambers on both sides of the electrophoresis tank and soaked in the buffer. An electric field is applied between the two buffer chambers, and the biological molecules can move in the gel under the action of the electric field.

[0003] The traditional electrophoresis tank is used to store buffer and gel and use electric field during the experiment. During the experiment, the position of the indicator electrophoresis in the spot hole can only be estimated to estimate the position of the gel electrophoresis of the biomolecule, but the electrophoresis effect, whether the band is clear, whether the shape is regular, the exact position of the band, etc. cannot be directly observed in real time. The only way is to cut off the power to stop the electrophoresis, take out the gel and place it in the UV observation instrument for observation. Not only is the operation cumbersome, but it is also easy to cause the gel to break and contaminate, and it is also easy to pollute the external experimental environment. Summary of the invention

[0026] In the present utility model, see the attached Figures 2 to 7 The relevant structure shown in . Figures 1 to 8 Middle: horizontal support foot 1, buffer chamber 2, electrophoresis comb 3, electrode column 4, safety cover 5, electric wire 6, glue making door 7, gel disc 8, tank body 9, ultraviolet lamp tube 10, metal part 101, pin 11, protective tube 12, round nut 13, left buckle 14, left compression spring 15, right buckle 16, upper end limit part 17, middle hinge part 18, left mounting part 19, right mounting part 20, right compression spring 21, right hinge shaft 22, right hinge hole 23, waterproof rubber ring 24, corrugated tube 25.

[0027] In this embodiment, an electrophoresis tank for biological experiments is mainly composed of horizontal legs 1, tank body 9, gel plate 8, electrophoresis comb 3, gel making door 7, fluorescent ruler, safety cover 5 and electrical wire 6. The safety cover 5 is equipped with an ultraviolet lamp 10, the tank body 9 and the safety cover 5 are respectively made of anti-ultraviolet acrylic or polarized material, the ultraviolet lamp 10 and the safety cover 5 adopt a detachable connection structure, and the pins of the ultraviolet lamp 10 pass through the safety cover 5 and are connected to the external circuit.

[0028] The pin 11 of the ultraviolet lamp 10 is in an L-shaped structure, one end of the pin 11 is plug-connected to the metal part 101 of the ultraviolet lamp 10, and the other end of the pin 11 is connected to the external circuit through the safety cover 5. The ultraviolet lamp 10 is connected to the safety cover 5 through a connecting block structure.

[0029] The connecting end of the pin 11 and the metal part 101 is sleeved with a round nut 13, and the round nut 13 is threadedly connected to the round hole on the waterproof rubber ring; the round nut 13 is provided to facilitate the installation of the pin 11, and is more conducive to the waterproof and steam-proof effect of the metal part 101 of the ultraviolet lamp tube 10. The round nut 11 is connected to one end of the bellows 25, and the bellows 25 is sleeved on the turning part of the pin 11. The other end of the bellows 25 is connected to the bottom of the protective tube 12, and the protective tube 12 is sleeved on the upper part of the pin 11. The connection strength between the protective tube 12 and the pin 11 should be suitable for smooth sliding between the two for easy disassembly. The outer diameter of the protective tube 12 can be bonded to the safety cover 5 with glue, or it can be directly installed without bonding; because the ultraviolet lamp tube 10 is mainly installed on the safety cover 5 by the connection block structure;

[0030] The top of the protective tube 12 passes through the safety cover and extends to the outside of the safety cover 5; the protective tube 12, the bellows 25 and the round nut 13 are made of non-metallic materials, such as PVC materials or rubber materials.

[0031] The metal parts 101 at both ends of the ultraviolet lamp tube 10 are mounted with waterproof rubber rings 24 .

[0032] The waterproof rubber ring 24 can be made longer, and the buckle is clamped on the waterproof rubber ring 24, which is more conducive to protecting the ultraviolet lamp tube 10 during the disassembly and assembly process.

[0033] The ultraviolet lamp tube 10 is connected to the safety cover 5 via a connecting block structure.

[0034] The connecting block structure is placed on the safety cover 5, and is provided with an upper end limiting portion 21, an intermediate hinged portion 18 and an installation portion. The upper end limiting portion 21 is located on the upper surface of the safety cover 5, and the intermediate hinged portion 18 and the installation portion extend into the safety cover 5 respectively. A buckle is installed on the intermediate hinged portion 18, and the buckle is connected to the installation portion through a compression spring.

[0035] The mounting parts are symmetrically arranged in two parts: a left mounting part 19 and a right mounting part 20; the middle hinge part 18 is provided with two symmetrically arranged semicircular buckles: a left buckle 14 and a right buckle 16, and the two semicircular buckles are respectively connected to the respective adjacent mounting parts through compression springs; the left buckle 14 is connected to the left mounting part 19 through a left compression spring 15, and the right buckle 16 is connected to the right mounting part 20 through a right compression spring 21. Taking the structure of the right buckle 16 as an example, the right hinge shaft 22 on the right buckle 16 is placed in the right hinge hole 23 of the middle hinge part 18.

[0036] The right buckle 14 is in contact and movable connection with the outer circumference of the right half of the ultraviolet lamp 16; the left buckle 14 is also in contact and movable connection with the outer circumference of the left half of the ultraviolet lamp 16; whether it is the left buckle 14 or the right buckle 16, the part of the ultraviolet lamp 16 supported by the extended end of the buckle needs to exceed the radius of the lamp in the horizontal direction; Figure 5 As shown in , the ultraviolet lamp tube 16 is supported more stably.

[0037] The safety cover 5 is provided with a first hole 501, a second hole 502 and a third hole 503, which are respectively adapted to the structures of the left mounting part 19, the middle hinge part 18 and the right mounting part 20 in the connecting block structure, which is more conducive to the stable installation of the connecting block structure. It is also possible to adopt a structure in which the aforementioned three mounting holes are merged into one mounting hole.

[0038] The design principle of the utility model is as follows: a small ultraviolet lamp tube 10 is added inside the electrophoresis tank, the power supply of the ultraviolet lamp tube 10 is provided by the power supply of the electrophoresis instrument, and the electrophoresis tank is made of anti-ultraviolet acrylic material or polarized material, so as to realize real-time observation of the electrophoresis process during the electrophoresis process and ensure the safety of the experimenters.

[0039] The drawings in this embodiment are described by taking a horizontal electrophoresis tank as an example. Figure 1 The improvement on the basis of the prior art expressed is mainly in the structure of the safety cover 5 and the ultraviolet lamp 10 installed thereon. The ultraviolet lamp 10 is installed on the lower side of the safety cover 5, and the ultraviolet light emitted by the ultraviolet lamp 10 can irradiate the gel inside the electrophoresis tank. The pin 11 of the ultraviolet lamp 10 passes upward through the safety cover 5 and extends outside the safety cover 5. The power supply of the electrophoresis instrument increases one or more power output groups to supply power to the ultraviolet lamp 10 (the number of ultraviolet power supply groups can be the same as the number of power supply groups of the electrophoresis tank). Since the service life of the ultraviolet lamp 10 is much shorter than the service life of the power supply and the electrophoresis tank of the electrophoresis apparatus, the ultraviolet lamp 10 is made to be detachable and replaceable. When the ultraviolet lamp 10 needs to be replaced, the left buckle 14 and the right buckle 16 only need to overcome the pressure of the left compression spring 15 and the right compression spring 21 respectively, and the left and right buckles 14 and 16 are separated from the ultraviolet lamp 10, and then the pin 11 is pushed downward to disengage the pin 11 from the protective tube 12, so that the ultraviolet lamp 10 can be detached from the safety cover 5, and the ultraviolet lamp 10 can be removed from the safety cover 5.

[0040] In order to ensure the safety of the experimenters, the tank body 8 and the safety cover 5 are made of anti-ultraviolet acrylic or polarized material to prevent the ultraviolet rays inside the electrophoresis tank from passing through the electrophoresis tank and radiating into the external environment.

[0041] The structure of the vertical electrophoresis tank is similar to that of the horizontal electrophoresis tank, which is not described in detail here; the ultraviolet lamp tube 10 can also be installed on the inner side of the safety cover 5, and the pin 11 of the ultraviolet lamp tube 10 is extended upward through the safety cover 5 to the outside to connect to the power supply.

[0042] The present invention is not limited to the contents listed in the above embodiments, and any structural equivalent replacement made within the protection scope of the present invention shall be deemed to be within the protection scope of the present invention.
