Description

Technical Field

[0001] This utility model relates to the field of dripping device technology, specifically a dripping device for bactericide experiments. Background Technology

[0002] In sterilization experiments, the disinfectant dropper is a specialized device used in the laboratory to precisely control the amount of disinfectant added and the operating conditions.

[0003] The current drip apparatus used in disinfectant experiments poses significant safety hazards. The device adopts a "bottom-mounted" design, requiring the experimenter to place the petri dish directly below the dripper for sample addition. When the experimenter repeatedly adjusts the position of the petri dish, the operator's hand will periodically enter the projection range of the dripping area. During the dripping process, the disinfectant will splash onto the experimenter's limbs, and residual liquid from the device may also accidentally drip onto the experimenter's limbs, exposing the experimenter to the risk of chemical burns or toxic exposure.

[0004] Therefore, a dripping device for bactericide experiments is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a dripper for bactericide experiments to solve the problems mentioned in the background art. To achieve the above objective, this utility model provides the following technical solution: A dripper for bactericide experiments includes an operating table. A support column is welded to the top of the operating table. A rotating rod is rotatably sleeved on the outside of the support column. A clamping assembly is welded around the rotating rod. A second fixing plate is fixedly sleeved on the outside of the support column. A liquid storage tank is fixedly sleeved inside the second fixing plate. A flow control valve is connected to the bottom of the liquid storage tank. A first fixing plate is rotatably sleeved on the outside of the support column. A support slide rod is slidably sleeved inside the first fixing plate. A sealing cover is installed at the bottom end of the support slide rod through a bearing. A limit assembly is installed on one side of the operating table.

[0006] Preferably, the bottom of the operating table is welded with four support legs, and the four support legs are located at the four corners of the bottom of the operating table.

[0007] Preferably, the sealing cap is connected to the top of the liquid storage tank by a threaded engagement, and a limit plate is welded to the top of the support column.

[0008] Preferably, the clamping assembly includes a base welded to one side of the rotating rod, and a support plate is welded to each of the two sides of the top of the base, and two positioning slots are provided on the top of the operating table.

[0009] Preferably, two first spring slide rods are slidably installed inside the support plate, and a clamping plate is welded to one side of each of the two first spring slide rods.

[0010] Preferably, the limiting component includes a mounting groove formed on one side of the operating table, and a plurality of second spring slide rods are fixed inside the mounting groove.

[0011] Preferably, a sliding plate is slidably sleeved on the outer side of a plurality of second spring slide rods, and a control plate is welded to one side of the sliding plate, the control plate extending out of the interior of the mounting groove.

[0012] Preferably, a limiting baffle is welded to each of the two sides of the top of the skateboard, and the limiting baffle is used in conjunction with the positioning groove.

[0013] Compared with the prior art, this utility model provides a dripping device for bactericide experiments, which has the following beneficial effects:

[0014] Multiple petri dishes are clamped above multiple bases. After the current petri dish completes the sterilization experiment, the current base is released by the control limiting component. Since the rotating rod is sleeved on the outside of the support column, the experimenter can rotate the rod by moving other bases, thereby moving the next petri dish fixed above the base to below the volume control valve for the drip experiment. During this process, the experimenter's limbs can be prevented from entering the drip area, thus preventing the sterilizing agent from dripping onto the experimenter's limbs and improving the protection of the experimenter.

[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. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Example 1: See Figure 1 — Figure 5 A disinfectant dripper for testing includes an operating table 1. A support column 3 is welded to the top of the operating table 1. A rotating rod 13 is rotatably sleeved on the outside of the support column 3. A clamping assembly 10 is welded to each of the four sides of the rotating rod 13. A second fixing plate 9 is fixedly sleeved on the outside of the support column 3. A liquid storage tank 8 is fixedly sleeved inside the second fixing plate 9. A flow control valve 2 is connected to the bottom of the liquid storage tank 8. A first fixing plate 5 is rotatably sleeved on the outside of the support column 3. A support slide rod 6 is slidably sleeved inside the first fixing plate 5. A sealing cover 7 is installed at the bottom end of the support slide rod 6 through a bearing. A limit assembly 11 is installed on one side of the operating table 1.

[0023] The clamping assembly 10 includes a base 1001 welded to one side of the rotating rod 13, and a support plate 1004 is welded to each of the two sides of the top of the base 1001. Two positioning slots 1005 are opened on the top of the operating table 1.

[0024] Two first spring slide rods 1003 are slidably installed inside the support plate 1004, and a clamping plate 1002 is welded to one side of the two first spring slide rods 1003.

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 5As shown, during the experiment, the petri dish can be clamped above multiple bases 1001. By pulling the two clamps 1002 above the base 1001 relative to each other, the distance between the two clamps 1002 is widened. Then, the petri dish is placed inside the two clamps 1002. The first spring slide rod 1003 supports the two clamps 1002 to clamp the sides of the petri dish. After the current petri dish completes the sterilization experiment, the current base 1001 is released by controlling the limiting component 11. Since the rotating rod 13 is rotated and sleeved on the outside of the support column 3, the experimenter can rotate the rotating rod 13 by moving other bases 1001, thereby moving the next petri dish fixed above the base 1001 to below the volume control valve 2 for the drip experiment. During this process, the experimenter's limbs can be prevented from entering the drip area, thus preventing the sterilizing agent from dripping onto the experimenter's limbs, thereby improving the protection of the experimenter.

[0026] Example 2: Four support legs 12 are welded to the bottom of the operating table 1, and the four support legs 12 are located at the four corners of the bottom of the operating table 1. The sealing cover 7 is connected to the top of the liquid storage tank 8 by thread engagement. The top of the support column 3 is welded with a limit plate 4. The limit component 11 includes an installation groove 1101 opened on one side of the operating table 1. Multiple second spring slide rods 1105 are fixed inside the installation groove 1101. A slide plate 1104 is slidably sleeved on the outside of the multiple second spring slide rods 1105. A control plate 1102 is welded to one side of the slide plate 1104. The control plate 1102 extends out of the interior of the installation groove 1101. A limit baffle 1103 is welded to both sides of the top of the slide plate 1104. The limit baffle 1103 is used in conjunction with the positioning groove 1005.

[0027] Specifically, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the four support legs 12 welded to the top of the operating table 1 ensure that the entire device is stably placed on the experimental table. Since the sealing cover 7 and the liquid storage tank 8 are connected by a threaded engagement, and the top of the sealing cover 7 is rotatably installed with the bottom end of the support slide rod 6, the sealing cover 7 and the liquid storage tank 8 can be disassembled by rotating the sealing cover 7. Because the first fixing plate 5 is rotatably sleeved on the outside of the limiting plate 4, when the sealing cover 7 is removed, moving the first fixing plate 5 can move the sealing cover 7 away from the top of the liquid storage tank 8, thus facilitating the observation and filling of the liquid stored inside the liquid storage tank 8 by the experimental personnel. Two positioning grooves 1 are provided on the top of the operating table 1. 005, and the positioning groove 1005 is provided with a limiting baffle 1103. The two limiting baffles 1103 can limit the base 1001 located between the two limiting baffles 1103, thereby preventing the rotation of the rotating rod 13 from causing the culture dish below the volume control valve 2 to shift position. The experimenter presses down the control plate 1102 to drive the slide plate 1104 to slide down along the installation direction of the second spring slide rod 1105, thereby storing the limiting baffle 1103 into the installation groove 1101, so that the limiting baffle 1103 is disengaged from the positioning groove 1005. At this time, the rotating rod 13 can be rotated to change the culture dish.

[0028] Working principle: The petri dish is clamped above multiple bases 1001. By pulling the two clamping plates 1002 above the bases 1001 relative to each other, the distance between the two clamping plates 1002 is widened. Then, the petri dish is placed inside the two clamping plates 1002. The first spring slide rod 1003 supports the two clamping plates 1002 to clamp the sides of the petri dish. Since the top of the operating table 1 has two positioning slots 1005, and the positioning slots 1005 are equipped with limiting baffles 1103, the bases 1001 located between the two limiting baffles 1103 can be limited. This prevents the petri dish below the volume control valve 2 from shifting due to the rotation of the rotating rod 13. Then, the volume control valve 2 is opened, and the disinfectant stored in the storage tank 8 drips into the petri dish through the volume control valve 2. After the current petri dish has completed the sterilization experiment, the experimenter presses down on the control plate 1102 to drive the slide plate 1104 to slide down along the installation direction of the second spring slide rod 1105, thereby storing the limiting baffle 1103 into the installation groove 1101, so that the limiting baffle 1103 is disengaged from the positioning groove 1005. At this time, the rotating rod 13 can be rotated to change the petri dish.
