[0001] This utility model relates to the field of reagent dispensing technology, and in particular to a reagent dispensing device. Background Technology

[0002] In the process of conducting chemical experiments, especially organic chemistry experiments, a large number of organic chemical reagents and solvents are usually required. Most of these organic substances are flammable and explosive, and have varying degrees of toxicity. These are what are commonly referred to as hazardous chemical reagents.

[0003] However, during chemical experiments, it is usually necessary for the experimenter to manually extract chemical reagents. When extracting chemical reagents, if the storage bottle is not fixed and restrained, the storage bottle is easily touched and tipped over by the experimenter, which will cause the reagents inside the storage bottle to spill out and affect the normal progress of the chemical experiment. Utility Model Content

[0004] In view of this, the purpose of this utility model is to provide a reagent dispensing device to solve the problem that the storage bottle is not fixed and limited, and the storage bottle is easily touched and tilted by the experimenter, which leads to the reagent inside the storage bottle spilling out.

[0005] To achieve the above objectives, this utility model provides a reagent dispensing device, comprising a housing and a lifting plate. The housing is equipped with a spacing adjustment structure for driving the lifting plate to move vertically. An inlet pipe is fixedly connected to the bottom end of the housing, a pump is fixedly connected inside the housing, and an outlet pipe is fixedly connected to the outer wall of the housing. The input end of the pump is fixedly connected to the top end of the inlet pipe, and the output end of the pump is fixedly connected to the outlet pipe. A support plate is rotatably connected to the bottom end of the lifting plate, and a positioning mechanism for positioning the support plate is installed on the lifting plate.

[0007] Preferably, a support is fixedly connected to the lead screw, and an insert rod passes through the support. Several slots are provided at the bottom of the mounting plate, the top of the insert rod is located in the corresponding slot, and a fixing plate is fixedly connected to the bottom of the insert rod. The top of the fixing plate and the bottom of the support are connected by a tension spring.

[0008] Preferably, the outer side of the inlet pipe is fitted with a sealing tube, the outer side of the sealing tube is fitted with a threaded sleeve, and the top end of the threaded sleeve is fixedly connected to the bottom of the outer shell. The outer wall of the sealing tube is provided with threads that are compatible with the threaded sleeve.

[0009] Preferably, an anti-slip pad is fixedly connected to the tray.

[0010] Preferably, the positioning mechanism includes a rotating plate rotatably mounted on the bottom end of the lifting plate, a positioning groove adapted to the rotating plate is provided on the support plate, and the two sides of the rotating plate are in contact with the inner walls of the two sides of the positioning groove, an iron plate is fixedly connected to the rotating plate, and a magnet block adapted to the iron plate is fixedly connected to the support plate, and the magnet block is in contact with the iron plate.

[0011] The beneficial effects of this invention are as follows: The experimenter places the storage bottle containing chemical reagents under the outer shell, inserts the inlet tube into the storage bottle, and drives the tray to rotate relative to the lifting plate to make the tray horizontal.

[0022] This specification provides a reagent dispensing device according to one or more embodiments, such as... Figure 1 , Figure 2 and Figure 3As shown, the device includes a housing 1 and a lifting plate 2. The housing 1 is equipped with a spacing adjustment structure for driving the lifting plate 2 to move vertically. An inlet pipe 3 is fixedly connected to the bottom of the housing 1. A pump 4 is fixedly connected inside the housing 1. An outlet pipe 5 is fixedly connected to the outer wall of the housing 1. The input end of the pump 4 is fixedly connected to the top end of the inlet pipe 3, and the output end of the pump 4 is fixedly connected to the outlet pipe 5. A support plate 6 is rotatably connected to the bottom of the lifting plate 2. A positioning mechanism for positioning the support plate 6 is installed on the lifting plate 2. The experimenter places a storage bottle 7 containing chemical reagents under the housing 1, inserts the inlet pipe 3 into the storage bottle 7, and drives the support plate 6 to rotate relative to the lifting plate 2, so that the support plate 6... The plate 6 is in a horizontal position, and the positioning mechanism positions the plate 6. The plate 6 supports the storage bottle 7. The lifting plate 2 is driven to move upward relative to the outer shell 1 through the spacing adjustment structure, so that the plate 6 drags the storage bottle 7 upward synchronously. Finally, the top of the storage bottle 7 and the bottom of the outer shell 1 are tightly attached, thus fixing the storage bottle 7. The outer shell 1 seals the bottle opening of the storage bottle 7 to prevent the reagent inside the storage bottle 7 from spilling out, improving safety. The liquid pump 4 is started, and the liquid pump 4 draws the reagent in the storage bottle 7 into the liquid outlet pipe 5 through the liquid inlet pipe 3. The reagent in the storage bottle 7 can be automatically discharged through the liquid outlet pipe 5, without the need for manual extraction of the reagent in the storage bottle 7, improving convenience and safety.

[0023] In embodiments of this utility model, such as Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the spacing adjustment structure includes a mounting plate 16 fixedly installed on the outer wall of the housing 1. A lead screw 8 is rotatably connected to the bottom of the mounting plate 16. A threaded groove 9 and a sliding groove 10 are respectively opened on the top of the lifting plate 2. The bottom end of the lead screw 8 is located in the threaded groove 9. A sliding plate 11 is slidably installed in the sliding groove 10, and the top end of the sliding plate 11 is fixedly connected to the mounting plate 16. A support part 12 is fixedly connected to the lead screw 8. An insert rod 13 passes through the support part 12. Several slots 17 are opened at the bottom of the mounting plate 16. The top end of the insert rod 13 is located in the corresponding slot 17. A fixed plate 14 is fixedly connected to the bottom end of the insert rod 13. The top end of the fixed plate 14 and the bottom end of the support part 12 are connected by a tension spring 15. A sealing tube 18 is slidably sleeved on the outside of the liquid inlet pipe 3. A threaded sleeve 19 is sleeved on the outside of the sealing tube 18, and the top end of the threaded sleeve 19 is fixedly connected to the bottom of the housing 1. The outer wall of the sealing tube 18 is provided with threads that are compatible with the threaded sleeve 19. The experimenter drives the fixed plate 14 to move downwards, causing the top of the insertion rod 13 to disengage from the slot 17, thus releasing the restriction on the position of the lead screw 8. The tension spring 15 is in a stretched state. The experimenter drives the support part 12 and the lead screw 8 to rotate, so that the lead screw 8 drives the lifting plate 2 to move vertically relative to the mounting plate 16 and the outer shell 1, and the slide groove 10 slides relative to the sliding plate 11. When it is not necessary to adjust the height of the lifting plate 2, the experimenter releases the fixed plate 14, and the tension spring 15 drives the fixed plate 14 and the insertion rod 13 to move upwards, so that the top of the insertion rod 13 is inserted into the corresponding slot 17, thus fixing the lead screw 8 relative to the mounting plate 16 and the outer shell 1. Before the experiment begins, the experimenter drives the sealing tube 18 to rotate relative to the threaded sleeve 19, so that the sealing tube 18 slides relative to the liquid inlet tube 3, thereby adjusting the distance between the bottom end of the sealing tube 18 and the outer shell 1, and adjusting the initial height of the bottom end of the sealing tube 18 according to the specifications of the storage bottle 7.

[0024] In embodiments of this utility model, such as Figure 1 , Figure 2 and Figure 5As shown, an anti-slip pad 20 is fixedly connected to the tray 6. The positioning mechanism includes a rotating plate 21 rotatably mounted on the bottom end of the lifting plate 2. The tray 6 has a positioning groove 22 adapted to the rotating plate 21, and the two sides of the rotating plate 21 are in contact with the inner walls of the two sides of the positioning groove 22. An iron plate 23 is fixedly connected to the rotating plate 21, and a magnet block 24 adapted to the iron plate 23 is fixedly connected to the tray 6, and the magnet block 24 is in contact with the iron plate 23. When the storage bottle 7 is fixed between the tray 6 and the outer shell 1, the bottom of the storage bottle 7 is in contact with the top of the anti-slip pad 20. Through the design of the anti-slip pad 20, the slippage of the storage bottle 7 is reduced. The bottom end of the rotating plate 21 is located in the positioning groove 22, which limits the position of the tray 6 relative to the horizontal direction of the tray 6. This prevents the tray 6 from rotating and wobbling relative to the lifting plate 2. The magnet 24 and the iron plate 23 are magnetically attracted to each other. The design of the iron plate 23 and the magnet 24 prevents the rotating plate 21 from rotating and wobbling relative to the tray 6 due to non-human factors. The experimenter drives the rotating plate 21 and the iron plate 23 to rotate so that the bottom end of the rotating plate 21 is no longer located in the positioning groove 22 and the iron plate 23 is no longer magnetically attracted to the magnet 24. This releases the limitation on the position of the tray 6, and the tray 6 can then rotate relative to the lifting plate 2.
