Description

Technical Field

[0001] This utility model relates to the field of screening instrument technology, and in particular to a rapid screening instrument for genetically modified soybean components. Background Technology

[0002] Soybeans, as one of the world's most important oilseed crops and protein sources, account for a very high proportion in the planting and trade sectors. However, the safety, environmental impact, and market regulation of genetically modified crops have always been a major concern. As a core detection tool, the rapid screening instrument for genetically modified soybean components is extremely important in regulating industrial development, maintaining market fairness, and ensuring food security. It is an indispensable piece of technical equipment in the modern agricultural industrial system.

[0003] When researchers use a traditional rapid screening instrument for genetically modified soybean components, the soybean sample to be tested must first be processed and placed into a test tube. The test tube containing the sample is then placed in the rack inside the screening instrument. When using thinner test tubes, a large gap exists between the test tube and the wall of the rack, causing the test tube to tip over or shift, thus affecting the accuracy of the test. To accommodate thinner test tubes, the entire rack needs to be replaced. However, the racks inside existing screening instruments are mostly one-piece structures, and replacing the entire rack increases operating costs. Therefore, a rapid screening instrument for genetically modified soybean components is needed to solve these problems. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a rapid screening instrument for genetically modified soybean components.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: A rapid screening instrument for genetically modified soybean components includes a screening instrument body. A cover plate is hinged to one side of the top of the screening instrument body, and a handle is fixedly connected to one side of the cover plate. A cavity is opened at the top of the screening instrument body, and a placement rack is provided inside the cavity. A placement plate is provided at the top of the placement rack, and several placement slots are opened through the top of the placement plate. Slots are opened on both sides of the top of the placement rack, and inserts are fixedly connected to both sides of the placement plate. The inserts are adapted to the slots.

[0006] By adopting the above technical solution, and by setting up a placement rack, placement plate, placement groove, insert block and slot, it is easy for experimental personnel to disassemble and replace the placement plate. When experimental personnel need to use thinner test tubes for transgenic detection, they only need to take out and replace the placement plate.

[0007] Preferably, slots are provided on both sides of the top of the placement rack, a connecting rod is fixedly connected inside the slot, a slider is slidably sleeved on the outside of the connecting rod, and a locking plate is provided on the top of the slider.

[0008] By adopting the above technical solution, and by setting a slot, connecting rod, locking plate and slider, the locking plate can be pushed to the top of the insert to lock the placement plate and prevent the insert from falling out of the slot.

[0009] Preferably, a spring is fixedly connected to one side of the slider, one end of the spring is fixedly connected to one side of the inner wall of the slot, and the spring is sleeved on the outside of the connecting rod.

[0010] By adopting the above technical solution and setting a spring, when it is necessary to further lock the placement plate, the spring rebound potential energy causes the locking plate to move quickly to the top of the insertion block, thereby quickly locking the placement plate. This eliminates the need for the experimenter to manually push the locking plate to the top of the insertion block, saving the experimenter's operation time.

[0011] Preferably, a circular groove is formed at the bottom of the inner wall of the placement rack, a lead screw is rotatably connected inside the circular groove, a damping bearing is installed inside the circular groove, the lead screw is rotatably connected to the circular groove through the damping bearing, a support plate is slidably connected to the inner side of the placement rack, the support plate is threaded onto the outer side of the lead screw, and a knob is fixedly connected to the top of the lead screw.

[0012] By adopting the above technical solution, and by setting up a circular groove, damping bearing, lead screw, and support plate, test tubes of different specifications and lengths can be supported. By setting up a knob, the experimenter's hand is prevented from being scratched by direct contact with the sharp part of the lead screw.

[0013] Preferably, the top of the locking plate is threaded with an internal hexagon screw, and the top of the slider has a threaded hole. The locking plate is connected to the slider by the internal hexagon screw.

[0014] By adopting the above technical solution and setting an internal hexagon screw, when a foreign object is stuck in the slot or spring and the slider cannot slide, the experimenter can use a tool to unscrew and remove the internal hexagon screw, so that the locking plate is separated from the slider, and the locking plate located on the top of the insert can be removed to facilitate the replacement of the placement plate.

[0015] Preferably, the cover plate has a groove on its front side, and a sealing gasket is fixedly connected inside the groove. The sealing gasket is made of rubber.

[0016] By adopting the above technical solution and setting a sealing gasket, the gap between the cover and the top of the screening instrument can be reduced when the cover is closed, effectively preventing external dust from entering the screening instrument during the genetically modified detection process.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. By setting up a placement rack, placement plate, slot, connecting rod, slider, locking plate, and spring, when the experimenter needs to use thinner test tubes for transgenic detection experiments, they only need to push the locking plate, take out the original placement rack, and replace it with a placement plate with a placement slot that is compatible with thinner test tubes. There is no need to replace the entire test tube rack, thus reducing the cost of use.

[0018] 2. By setting a lead screw, knob, and support plate, turning the knob can adjust the support plate up and down according to the length of the test tube, thereby stably supporting test tubes of different lengths and improving the stability of the test tubes when placed.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0022] Reference Figure 1 and Figure 2A rapid screening instrument for genetically modified soybean components includes a screening instrument body 1, model number TW-ZJY1. A cover plate 2 is hinged to one side of the top of the screening instrument body 1. A handle 3 is fixedly connected to one side of the cover plate 2. The handle 3 is covered with rubber material on the outside for easy gripping by the experimenter. A groove is opened on the front of the cover plate 2, and a sealing gasket is fixedly connected inside the groove. The sealing gasket is made of rubber material. When the cover plate 2 is closed, the sealing gasket is located between the cover plate 2 and the screening instrument body 1, which can prevent dust in the air from entering through the gap between the cover plate 2 and the screening instrument body 1.

[0023] Reference Figures 1-3 The screening instrument body 1 has a cavity at the top, and a placement rack 4 is placed inside the cavity. A placement plate 5 is placed on the top of the placement rack 4. Several placement slots 6 are opened through the top of the placement plate 5. Slots are opened on both sides of the top of the placement rack 4. Insert blocks 16 are fixedly connected to both sides of the placement plate 5. The insert blocks 16 are adapted to the slots. When the experimenter needs to replace the placement plate 5, he only needs to pick up the placement plate 5. The placement plate 5 drives the insert blocks 16 to move, so that the insert blocks 16 are separated from the slots. This can realize the quick replacement of the placement plate 5. The operation is convenient and fast.

[0024] Reference Figures 1-3 The bottom of the inner wall of the placement rack 4 has a circular groove. A lead screw 13 is rotatably connected inside the groove. A damping bearing is installed inside the groove. The lead screw 13 is rotatably connected to the groove through the damping bearing. A support plate 12 is slidably connected to the inner side of the placement rack 4. The support plate 12 is threaded onto the outside of the lead screw 13. A knob 14 is fixedly connected to the top of the lead screw 13. When the experimenter needs to use the support plate 12 to support the test tube, he only needs to turn the knob 14. The rotation of the knob 14 drives the lead screw 13 to rotate. The rotation of the lead screw 13 drives the support plate 12 to rise. When the top of the support plate 12 reaches the height that can contact the bottom of the test tube, the knob 14 is stopped. At this time, the support plate 12 stably supports the test tube.

[0025] Reference Figures 1-4 The top of the placement frame 4 has slots 7 on both sides, and a connecting rod 8 is fixedly connected inside the slots 7. A slider 9 is slidably sleeved on the outside of the connecting rod 8. A locking plate 10 is provided on the top of the slider 9. An internal hexagon screw 15 is threaded through the top of the locking plate 10. A threaded hole is provided on the top of the slider 9. The locking plate 10 is connected to the slider 9 through the internal hexagon screw 15. When a foreign object is stuck in the slots 7 or the spring 11, making it impossible for the slider 9 to slide with the locking plate 10, and it is necessary to release the lock on the placement plate 5, the internal hexagon screw 15 can be unscrewed with a tool to separate the bottom of the locking plate 10 from the slider 9. At this time, the locking state of the placement plate 5 is released, which adds another locking method to the placement plate 5 and improves the flexibility of the screening instrument.

[0026] Reference Figures 1-4A spring 11 is fixedly connected to one side of the slider 9. One end of the spring 11 is fixedly connected to one side of the inner wall of the slot 7. The spring 11 is sleeved on the outside of the connecting rod 8. When the placement plate 5 needs to be replaced, the two locking plates 10 are pushed to move away from each other. The locking plates 10 drive the hexagonal screw 15 and the slider 9 to move. When the slider 9 moves, it squeezes the spring 11. The placement plate 5 is taken out and replaced. The inserts 16 on both sides of the replaced placement plate 5 are inserted into the slots. The locking plates 10 are stopped, and the spring 11 rebounds. The rebound of the spring 11 drives the slider 9, the hexagonal screw 15 and the locking plates 10 to move quickly until the slider 9 contacts the side of the inner wall of the slot 7 close to the placement plate 5. At this time, the slider 9 and the locking plates 10 stop moving. The bottom of the locking plates 10 contacts the top of the inserts 16, so that the replaced placement plate 5 can be quickly locked.

[0027] In this invention, the working principle is as follows: When the experimenter needs to change test tubes of different sizes for transgenic testing, the placement rack 4 is taken out of the cavity and placed on the experimental table. At this time, the position of the support plate 12 is adjusted according to the length of the test tube. First, the knob 14 is turned. The rotation of the knob 14 drives the lead screw 13 to rotate, and the rotation of the lead screw 13 drives the support plate 12 to rise. When the top of the support plate 12 reaches the height that can contact the bottom of the test tube, the knob 14 is stopped, and the two locking plates 10 are pushed to move in a direction away from each other. The locking plates 10 drive the internal hexagon screw 15 to move, and the internal hexagon screw 15 drives the slider 9 to move. When the slider 9 moves in the slot 7, it squeezes the spring 11, and the spring 11 is in a compressed state. As the locking plates 10 are continuously pushed, the bottom of the locking plates 10 and the insert block 1... Separate the top of plate 6. Remove the original placement plate 5 and replace it with a placement plate 5 that can accommodate test tubes of another size. Insert the inserts 16 on both sides of the replaced placement plate 5 into the slots. Stop pushing and release the locking plate 10. The spring 11 will spring back from its compressed state. The spring 11 will cause the slider 9 to move quickly in the slot 7. The rapid movement of the slider 9 will cause the hexagonal screw 15 to move quickly. The rapid movement of the hexagonal screw 15 will cause the locking plate 10 to move quickly until the slider 9 contacts the side of the inner wall of the slot 7 closest to the placement plate 5. The slider 9 and the locking plate 10 will then stop moving. The bottom of the locking plate 10 will contact the top of the insert 16. Place the test tube to be tested in the placement slot 6 and place the placement rack 4 in the cavity. Close the cover plate 2. The genetically modified components can then be detected using the screening instrument body 1.
