Description

Technical Field

[0001] This utility model relates to a molecular experimental gel electrophoresis tank that is easy to observe, belonging to the technical field of medical diagnostic auxiliary equipment. Background Technology

[0002] Gel electrophoresis tanks are commonly used molecular experimental equipment in hospitals (especially in laboratory departments, pathology departments, and molecular diagnostic centers). Their core purpose is to assist in disease diagnosis and treatment monitoring by separating biomolecules.

[0003] In gel electrophoresis for molecular experiments, the clarity of observation of molecular bands after electrophoresis directly affects the interpretation of experimental results. Traditional gel electrophoresis tanks have the following problems: the lighting equipment in gel electrophoresis tanks is mostly fixed, and when observing molecular bands after electrophoresis, uneven lighting often results in low brightness in key areas, making observation difficult, and even causing weak bands to be obscured. Summary of the Invention

[0004] The purpose of this invention is to provide a molecular experiment gel electrophoresis tank that is easy to observe, aiming to improve the problem of low clarity in local areas when observing molecular bands after electrophoresis in traditional gel electrophoresis tanks due to low brightness.

[0005] The present invention adopts the following technical solution:

[0006] A molecular experiment gel electrophoresis tank for easy observation includes a gel electrophoresis tank 100 and an observation auxiliary mechanism 200. The lower part of the gel electrophoresis tank 100 has an installation space for installing the observation auxiliary mechanism 200. The observation auxiliary mechanism 200 includes an illumination component 210 installed directly below the gel platform in the gel electrophoresis tank 100. The illumination component 210 includes a lamp body 214. Both ends of the lamp body 214 are slidably connected to slide rails 212, and the two ends of the slide rails 212 are located on both sides below the gel platform in the gel electrophoresis tank 100. One side of the lamp body 214 has a lever 215 that extends out of the corresponding slide rail 212 and is exposed.

[0007] In this technical solution, the user of the molecular experiment gel electrophoresis tank can move the lever 215 to drive the lamp body 214 to slide along the slide rail 212, thereby selectively adjusting the position of the required illumination, thus improving the problem of low clarity in local areas due to low brightness when observing molecular bands after electrophoresis in traditional gel electrophoresis tanks.

[0008] Preferably, the observation auxiliary mechanism 200 further includes a light-transmitting liner 222 with a background color, the liner 222 being disposed between the lamp body 214 and the bottom of the gel platform of the gel electrophoresis tank. The liner 222 solves the problem of insufficient contrast between bands and background caused by the monotonous background of existing molecular experimental gel electrophoresis tanks, especially for bands stained with different staining agents (such as blue, fluorescent, etc.), which are difficult to clearly identify.

[0009] Preferably, the lighting assembly 210 further includes a side frame 211, with both ends of the side frame 211 fixedly connected to both ends of the slide rail 212. Connecting blocks 213 are fixedly connected to both ends of the side frame 211 on the outer side of the slide rail 212. Bolts 213a are threaded through the connecting blocks 213 and abut against pre-drilled holes on the inner wall of the installation space of the gel electrophoresis tank 100. Adjusting the unscrewing length of the bolts 213a allows for adaptation to installation spaces of different sizes. This solves the problem that different models of gel electrophoresis tanks have significant structural differences, and that traditional observation auxiliary devices have poor versatility and are difficult to adapt to electrophoresis tanks of various sizes.

[0010] Furthermore, a rubber anti-slip pad is fixedly connected to the end of the bolt 213a, and the screwing end of the connecting block 213 is embedded in the connecting block 213.

[0011] Preferably, the middle part of the slide rail 212 is hollow, and the two ends of the slide rail 212 are respectively fixedly connected to the slide rods 218. The slide rods 218 pass through the reserved holes at both ends of the lamp body 214 and are slidably connected to the lamp body 214.

[0012] Furthermore, a limiting slider 217 is fixedly connected to one end of the lamp body 214, and the limiting slider 217 is slidably sleeved on a slide rod 218. The other end of the lamp body 214 is fixedly connected to the dial plate 215, and the dial plate 215 is slidably sleeved on another slide rod 218.

[0013] Furthermore, the slide bar 218 is fitted with two springs 219, with a gap between the two springs. The lever 215 or the limiting slider 217 is located in this gap. One end of the spring 219 abuts against the lever 215 or the limiting slider 217, and the other end abuts against the connecting block 213.

[0014] Furthermore, a circular handle is provided on the outer side of the dial 215.

[0015] Preferably, a diffuser plate 216 is provided on the outside of the lamp body 214, and the diffuser plate 216 is arc-shaped.

[0016] Furthermore, it also includes a limiting frame 221, which is U-shaped, with a stepped inner edge. The liner 222 is slidably inserted into the step of the limiting frame 221. The lower edge of the outer end of the liner 222 is fixedly connected to an edge 223, and the lower part of the edge 223 is provided with anti-slip texture. Connecting posts 224 are fixedly connected to the four corners of the limiting frame 221, and the bottom of the connecting posts 224 is fixedly connected to the upper part of the end of the slide rail 212.

[0017] The beneficial effects of this utility model are as follows:

[0018] 1) Flexible and adjustable illumination during use: The lamp body 214 in the illumination assembly can be slidably adjusted via the slide rail 212, which can precisely adapt to different gel sizes and lane distributions, allowing the light to be focused on the area to be observed, improving the uniformity of strip illumination, and making even weak strips clearly visible. This improves the problem of low clarity in local areas due to low brightness when observing molecular bands after electrophoresis in traditional gel electrophoresis tanks;

[0019] 2) Customizable background contrast: The backing plate 222 in the auxiliary observation component 220 can be flexibly changed according to the band color (e.g., blue bands with white backing plate, fluorescent bands with black backing plate), greatly improving the contrast between the bands and the background, facilitating quick and accurate band identification. This solves the problem of insufficient contrast between bands and background caused by the monotonous background in existing molecular experimental gel electrophoresis tanks, especially for bands stained with different dyes (e.g., blue, fluorescent, etc.), which are difficult to clearly identify.

[0020] 3) High versatility: By connecting the block 213 and the bolt, the observation auxiliary mechanism can be installed under gel electrophoresis tanks of different sizes, which has wide adaptability and reduces the procurement cost of experimental equipment; it solves the problem that the traditional observation auxiliary device has poor versatility and is difficult to adapt to electrophoresis tanks of various sizes due to the large differences in the structure of different models of gel electrophoresis tanks.

[0021] 4) Easy to operate: The liner can be quickly pulled out and replaced through the limiting frame, the lever of the lamp body is easy to manually adjust the position, and the arc design of the diffuser plate further optimizes the light scattering effect. The overall operation is simple and efficient, which improves the convenience of experimental observation.

[0022] 5) Stable and reliable structure: The elastic limit of the lamp body by the spring and the anti-slip fixation of the connecting block by the rubber anti-slip pad ensure the structural stability of the lighting component during use and avoid the lighting shift caused by vibration during operation or electrophoresis.

Detailed Implementation

[0028] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0029] See Figure 1 A molecular experiment gel electrophoresis tank for easy observation includes a gel electrophoresis tank 100 for conducting experiments and an observation auxiliary mechanism 200. The lower part of the gel electrophoresis tank 100 has an installation space for installing the observation auxiliary mechanism 200.

[0030] See Figure 2 The observation aid 200 includes an illumination assembly 210 installed directly below the gel platform in the gel electrophoresis tank 100.

[0031] See Figure 3 The lighting assembly 210 includes a lamp body 214; both ends of the lamp body 214 are slidably connected to slide rails 212, and the two ends of the slide rails 212 are located on both sides below the gel platform in the gel electrophoresis tank 100; one side of the lamp body 214 has a lever 215 that extends out of the corresponding slide rail 212 and is exposed, which can be combined with an attached... Figure 2 .

[0032] Combination Figure 1 , 2In addition to the above, the observation auxiliary mechanism 200 also includes an auxiliary observation component 220, which includes a liner 222. The liner 222 is located between the lamp body 214 and the bottom of the gel platform of the gel electrophoresis tank 100. In the illumination component 210, the lamp body 214 can be slidably adjusted via a slide rail 212, which can precisely adapt to different gel sizes and lane distributions, so that the light is focused on the area to be observed, improving the uniformity of strip illumination, and even weak strips can be clearly seen. The observation auxiliary mechanism 200 can be integrally molded or modularly assembled during production. The modular design facilitates quick adaptation to different electrophoresis tank specifications, while the integral molding provides stronger structural stability. Both forms can be quickly fixed to the gel electrophoresis tank 100 by screwing on the bolts 213a in the connecting block 213, improving installation efficiency.

[0033] Please see Figure 3 and Figure 4 The lighting assembly 210 also includes a side frame 211, with both ends of the side frame 211 fixedly connected to both ends of the slide rail 212. Connecting blocks 213 are fixedly connected to both ends of the side frame 211 on the outer side of the slide rail 212. Bolts 213a are threaded through the connecting blocks 213 and abut against pre-drilled holes on the inner wall of the installation space of the gel electrophoresis tank 100. Adjusting the unscrewing length of the bolts 213a (not shown in the attached figure) allows for adaptation to different sizes of installation spaces. Rubber anti-slip pads at the bolt ends increase friction with the outer wall of the electrophoresis tank, preventing the observation auxiliary mechanism 200 from sliding during use, ensuring stable lighting and liner positions, and improving the continuity and accuracy of observation.

[0034] A rubber anti-slip pad (not shown in the attached diagram) is fixedly connected to the end of the bolt inside the connecting block 213. The screwing end of the connecting block 213 is embedded in the connecting block 213. The embedded screwing end design prevents the screwing end from protruding, preventing accidental contact by the operator. At the same time, it makes the overall appearance of the observation auxiliary mechanism 200 more regular, reduces space occupation, and improves operational safety. The middle part of the slide rail 212 is hollow. The two ends of the slide rail 212 are fixedly connected to the slide rods 218 respectively. The two ends of the lamp body 214 are slidably connected to the slide rods 218 respectively. The slide rods 218 provide guidance for the sliding of the lamp body 214. The hollow design of the slide rail 212 can reduce the overall weight and provide space for the wiring of the lamp body 214, so that the wiring is hidden inside the slide rail 212 and avoids the wiring from getting tangled and affecting operation.

[0035] See Figure 3One end of the lamp body 214 is fixedly connected with a limit slider 217, the limit slider 217 is slidably sleeved on one sliding rod 218, the other end of the lamp body 214 is fixedly connected with a toggle plate 215, the toggle plate 215 is slidably sleeved on the other sliding rod 218, and a circular handle is arranged on the outer side of one end of the toggle plate 215 penetrating through the sliding rail 212; the circular handle is convenient for an operator to hold and push the toggle plate 215, so as to realize rapid sliding adjustment of the lamp body 214, meet the lighting requirements of different gel regions, and improve the convenience of operation.

[0036] Two sides of the sliding rod 218 are respectively sleeved with springs 219, and the ends of the springs 219 are respectively abutted against the limit slider 217 and the two sides of the sliding rod 218; the springs 219 can provide elastic buffering and positioning for the lamp body 214, prevent the lamp body 214 from excessive displacement due to inertia during sliding, and can assist the lamp body 214 to reset to the middle after releasing the hand, so as to improve the use experience.

[0037] As shown in Figure 3 , a light diffuser plate 216 is arranged outside the lamp body 214, and the light diffuser plate 216 is arranged in an arc shape; the arc-shaped light diffuser plate 216 can uniformly scatter the light of the lamp body 214 to the surroundings, making the light at the bottom of the gel more uniform, avoiding local strong light or shadows from affecting band observation, and improving band clarity.

[0038] With continued reference to Figure 3 , the auxiliary observation assembly 220 further comprises a limit frame 221, the limit frame 221 is arranged in a U shape, the inner edge of the limit frame 221 is arranged in a step shape, two sides of the liner plate 222 are inserted into the steps of the limit frame 221 in a limited sliding manner, the step design can limit the liner plate 222 in the vertical direction, prevent the liner plate 222 from tilting upward during use, ensure that the liner plate 222 is always located between the lamp body 214 and the gel platform, and guarantee the background contrast effect.

[0039] Referring to Figure 4 , the lower edge of the outer end of the liner plate 222 is fixedly connected with an edge ridge 223, and anti-slip patterns (not shown in the accompanying drawings) are arranged below the edge ridge 223; the anti-slip patterns can increase the friction force when the operator pulls and pushes the liner plate 222, which is convenient for quickly replacing liner plates 222 of different colors to adapt to different stained bands, and improves the flexibility of background contrast. Four corners of the limit frame 221 are respectively fixedly connected with connecting columns 224, and the bottoms of the connecting columns 224 are respectively and fixedly connected to the upper parts of the ends of the sliding rail 212; the connecting columns 224 form a stable connection between the limit frame 221 and the sliding rail 212, ensure that the relative positions of the auxiliary observation assembly 220 and the lighting assembly 210 are fixed, and avoid the observation effect being affected by component displacement.

[0040] In this utility model, the position of the lamp body in the lighting assembly can be slidably adjusted through the sliding rail, which can accurately adapt to different gel sizes and lane distributions, focus the light on the area to be observed, improve the uniformity of band illumination, and make even weak bands clearly visible.

[0041] The above are preferred embodiments of the present utility model. Those skilled in the art can make various changes or improvements based on this. Without departing from the overall concept of the present utility model, these changes or improvements should all fall within the scope of protection claimed by the present utility model.
