[0025] Please see Figures 1-8As shown, a bioanalytical device includes an operating table 1. A positioning structure 7 is mounted on the operating table 1, and the positioning structure 7 includes a fixing plate 701. The fixing plate 701 is fixedly connected to the operating table 1. Multiple perforated plates 8 are placed on the operating table 1.

A suction head 4 is installed on the housing 3. An electrophoresis tank 5 is installed on the operating table 1 through the moving structure 6.

[0026] As a technical optimization of this utility model, pull plates 706 are slidably connected inside both the fixed plate 701 and the push plate 712. Multiple limiting rods 705 are fixedly connected to the bottom end of the pull plate 706. Limiting holes 704 are formed on the protrusion 702, and the limiting rods 705 engage with the limiting holes 704. Multiple springs 707 are fixedly connected between the two pull plates 706 and the fixed plate 701 and the push plate 712, respectively. Pull rods 708 are fixedly connected to the pull plates 706. Pull rod 708 is slidably connected to fixed plate 701 and push plate 712 respectively. When placing perforated plate 8, first place the first perforated plate 8 on the operating table 1, so that the side of perforated plate 8 abuts against the end of fixed plate 701. Then pull rod 708, pull rod 708 drives pull plate 706 to slide upward. Pull plate 706 slides and at the same time drives limit rod 705 to no longer engage with limit hole 704 on protrusion 702. At the same time, pull plate 706 drives spring 707 to retract, and then pushes limit plate 703 until limit plate 703 is reached. 703 abuts against the orifice plate 8, and then the other orifice plates 8 are placed in sequence. After all the orifice plates 8 are installed, the pull rod 708 is released, the spring 707 returns to its original position and drives the pull plate 706 and the limiting rod 705 to slide downward, so that the limiting rod 705 engages with the limiting hole 704, thereby preventing the protrusion 702 and the limiting plate 703 from sliding again. Then, the multiple limiting plates 703 on the push plate 712 are adjusted to the same distance as the multiple limiting plates 703 on the fixed plate 701, and the second hydraulic rod 709 is activated. The pressure rod 709 retracts and drives the push rod 710 to move toward the orifice plate 8. The push rod 710 pushes the push plate 712 to slide until the push plate 712 and the limiting plate 703 both abut against the other end of the orifice plate 8, thereby positioning the orifice plate 8 and preventing the suction head 4 from having difficulty picking up samples from the orifice plate 8 when it is tilted during placement. At the same time, multiple orifice plates 8 can be placed on the operating table 1 at the same time through the positioning structure 7, which makes the operation more convenient and efficient. In addition, the push plate 712 can be set to position orifice plates 8 of different widths.

[0027] As a technical optimization of this utility model, a guide rod 711 is fixedly connected to the push plate 712, and the guide rod 711 is slidably connected to the operating table 1; the guide rod 711 has a guiding effect on the push plate 712, making the sliding of the push plate 712 more stable.

[0028] As a technical optimization of this utility model, the driving structure 2 includes a first motor 201, which is mounted on the operating table 1. A first lead screw 202 is fixedly connected to the output shaft of the first motor 201. The first lead screw 202 is rotatably connected to the operating table 1.

A second lead screw 205 is rotatably connected to the first slide rail 204. A second slider 209 is threadedly connected to the second lead screw 205. A housing 3 is fixedly connected to the second slider 209. A first hydraulic rod 210 is installed inside the housing 3. A suction head 4 is installed at the extended end of the first hydraulic rod 210. A second motor 206 is mounted on the first slide rail 204, and a worm gear 206 is fixedly connected to the output shaft of the second motor 206. 7. The worm 207 is rotatably connected to the first slide rail 204. A worm wheel 208 meshes with the worm 207, and the worm wheel 208 is fixedly connected to the second lead screw 205. The first motor 201 is started, which drives the first lead screw 202 to rotate. The first lead screw 202 drives the first slider 203 to slide. The sliding of the first slider 203 simultaneously drives the first slide rail 204 to slide left and right. Then, the second motor 206 is started, which drives the worm 207 to rotate. The worm 207 meshes with the worm wheel 208, causing the worm wheel 208 to drive the second lead screw 205 to rotate. The second lead screw 205 drives the second slider 209 to slide back and forth. The sliding of the second slider 209 simultaneously drives the housing 3 to slide, thereby causing the housing 3 to move the suction head 4. Then, the first hydraulic rod 210 is started, which drives the suction head 4 to extend and perform sample application. The suction head 4 sucks up the sample from the well plate 8 and then applies it to the electrophoresis tank 5.

[0029] As a technical optimization of this utility model, the movable structure 6 includes a second slide rail 601. Two second slide rails 601 are fixedly connected to the operating table 1. A stop block 603 is slidably connected to the second slide rail 601. An electrophoresis tank 5 is installed on the stop block 603. A suction head box 9 is installed on the operating table 1. A common connecting rod 604 is fixedly connected between the two stop blocks 603. The connecting rod 604 abuts against the connecting block 602. Pulling the handle of the electrophoresis tank 5 causes the electrophoresis tank 5 to move the stop block 603 in the second slide rail 603. Slide the second slide rail 601 until the connecting rod 604 abuts against the connecting block 602 to prevent the electrophoresis tank 5 and the stop block 603 from slipping off the second slide rail 601. Then, place the buffer solution and gel plate into the electrophoresis tank 5 in sequence. Next, push the handle of the electrophoresis tank 5 to make the electrophoresis tank 5 and the stop block 603 slide until the other side of the electrophoresis tank 5 abuts against the end of the second slide rail 601. Thus, the cooperation of the second slide rail 601 and the stop block 603 plays a good role in positioning the electrophoresis tank 5 and prevents the electrophoresis tank 5 from being tilted, which would affect the sample loading work.

[0030] In use, this invention first pulls the handle of the electrophoresis tank 5, causing the stop 603 to slide on the second slide rail 601 until the connecting rod 604 abuts against the connecting block 602, preventing the electrophoresis tank 5 and the stop 603 from slipping off the second slide rail 601. Then, the buffer solution and gel plate are placed into the electrophoresis tank 5 in sequence. Next, the handle of the electrophoresis tank 5 is pushed, causing the electrophoresis tank 5 and the stop 603 to slide until the other side of the electrophoresis tank 5 abuts against the end of the second slide rail 601. Thus, the cooperation of the second slide rail 601 and the stop 603 provides good positioning for the electrophoresis tank 5, preventing the electrophoresis tank 5 from being tilted and affecting the sample loading work. When placing the well plate 8, the first well plate 8 is first placed on the operating table 1, so that the side of the well plate 8 is flush with the fixing plate. The end of 701 contacts the contact point, then pull rod 708 is pulled. Pull rod 708 drives pull plate 706 to slide upward. As pull plate 706 slides, it causes limit rod 705 to no longer engage with limit hole 704 on protrusion 702. At the same time, pull plate 706 drives spring 707 to retract, then pushes limit plate 703 until limit plate 703 contacts hole plate 8. Then, other hole plates 8 are placed in sequence. After all hole plates 8 are installed, pull rod 708 is released. Spring 707 returns to its original position and drives pull plate 706 and limit rod 705 to slide downward, so that limit rod 705 engages with limit hole 704, thus preventing protrusion 702 and limit plate 703 from sliding further. Then, the multiple limit plates 703 on push plate 712 are adjusted to be aligned with the multiple limit plates on fixed plate 701. With the same spacing between the positioning plates 703, the second hydraulic rod 709 is activated. The second hydraulic rod 709 retracts and drives the push rod 710 to move towards the orifice plate 8. The push rod 710 pushes the push plate 712 to slide until both the push plate 712 and the limiting plate 703 abut against the other end of the orifice plate 8, thereby positioning the orifice plate 8 and preventing the suction head 4 from having difficulty picking up samples from the orifice plate 8 due to tilting when placed. At the same time, the positioning structure 7 allows multiple orifice plates 8 to be placed on the operating table 1 simultaneously, making the operation more convenient and efficient. The push plate 712 can also be used to position orifice plates 8 of different widths. The guide rod 711 guides the push plate 712, making the sliding of the push plate 712 more stable. The first motor 201 is activated, and the first motor 201 drives the second hydraulic rod 712 to move towards the orifice plate 8. When the lead screw 202 rotates, the first lead screw 202 drives the first slider 203 to slide. The sliding of the first slider 203 simultaneously drives the first slide rail 204 to slide left and right. Then, the second motor 206 is started, and the second motor 206 drives the worm gear 207 to rotate. The worm gear 207 meshes and transmits power to the worm wheel 208, causing the worm wheel 208 to drive the second lead screw 205 to rotate. The second lead screw 205 drives the second slider 209 to slide back and forth. The sliding of the second slider 209 simultaneously drives the housing 3 to slide, thereby causing the housing 3 to move the suction head 4. Then, the first hydraulic rod 210 is started, and the first hydraulic rod 210 drives the suction head 4 to extend for sample application. The suction head 4 sucks up the sample from the well plate 8 and then applies it to the electrophoresis tank 5. The suction head box 9 is designed to facilitate the placement of the suction head 4.
