[0002] The osmotic pressure molar concentration meter is designed based on the principle of freezing point depression. It usually consists of a refrigeration system, a thermistor for measuring current or potential difference, and an oscillator. During the measurement, the measuring probe is immersed in the center of the test solution.

[0003] However, when the existing equipment is used, since the mouth of the test bottle is open, although the test is generally carried out in a laboratory, there are still impurities, particulate matter (materials or instruments used in the laboratory may produce particulate matter, such as glass fragments, plastic particles, etc.) and volatile chemical reagents in the air in the laboratory. These objects enter the interior of the test bottle and may affect the internal environment of the test bottle, thereby affecting the test results. Therefore, there are certain deficiencies. In view of this, we propose an osmotic pressure molar concentration measuring device. Utility Model Content

[0007] Preferably, the upper end of the threaded rod rotates to penetrate the upper surface of the mounting plate, the inner wall of the groove is fixedly connected with a motor, the output end of the motor is fixedly connected to the threaded rod, and the outer surface of the threaded rod is threadedly sleeved with a displacement plate.

[0008] Preferably, the right side of the displacement plate is slidably sleeved on the outer surface of the limiting rod, and a detection probe is provided on the lower surface of the displacement plate.

[0009] Preferably, an L-shaped plate is provided on the left surface of the displacement plate, teeth are provided on the right surface of the L-shaped plate, and an outer gear cylinder is rotatably connected to the inner wall of the groove.

[0012] Preferably, two push rods are fixedly connected to the right side surface of the tooth plate, and the right ends of the two push rods are in contact with the left side surfaces of the two second protrusions.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] (1) In the osmotic pressure molar concentration determination device, when conducting a test, the test bottle is placed inside the storage groove, and then the second protrusion is pushed to move by the driving assembly. When the second protrusion moves, it will synchronously drive the dust cover to move, and when the dust cover moves, it will synchronously drive the L-shaped rod to move. When the L-shaped rod moves, the reset disk is slidably connected to the L-shaped rod, and there is a spring pushing the reset disk. Therefore, when the L-shaped rod moves, the reset disk will not move. When the reset disk slides to contact the inner wall of the sliding groove, it will be driven by the L-shaped rod. At this time, the spring will be compressed by the reset disk, and at this time, the dust cover will move to open the test bottle. Through the above structure, the test bottle can be in a sealed state before the test, so dust cannot enter the interior of the test bottle, avoiding dust from affecting the test results.

[0015] (2) The osmotic pressure molar concentration measuring device drives the threaded rod to rotate by a motor. Since the movement trajectory of the displacement plate is restricted, when the threaded rod rotates, it will simultaneously drive the displacement plate to move in the vertical direction. When the displacement plate moves, it will simultaneously drive the detection probe to descend, and use the L-shaped plate to drive the teeth to move. After the teeth move, they drive the outer gear cylinder to rotate. When the outer gear cylinder rotates, it drives the tooth plate to move horizontally. When the tooth plate moves, the push rod pushes the second protrusion to move. Through the above structure, when performing detection, it only needs to control the detection probe to descend. During the descent, the dust cover will automatically open without the need for additional operation by the staff. In addition, the dust cover can be automatically reset when the detection probe rises after the detection. BRIEF DESCRIPTION OF THE DRAWINGS

The inner wall of the groove 2 is provided with a driving assembly. When testing is carried out, the test bottle 4 is placed inside the storage groove 3, and then the driving assembly is used to push the second protrusion 11 to move. When the second protrusion 11 moves, it will synchronously drive the dust cover 5 to move. When the dust cover 5 moves, it will synchronously drive the L-shaped rod 6 to move. When the L-shaped rod 6 moves, the reset disk 8 is slidably connected to the L-shaped rod 6, and there is a spring 10 pushing the reset disk 8. Therefore, when the L-shaped rod 6 moves, the reset disk 8 will not move. When the reset disk 8 slides to contact the inner wall of the sliding groove 7, it will be driven by the L-shaped rod 6. At this time, the spring 10 will be compressed with the help of the reset disk 8, and at this time, the dust cover 5 will open the test bottle 4 after the movement. Through the above structure, the test bottle 4 can be in a sealed state before testing, so dust cannot enter the interior of the test bottle 4, thereby preventing dust from affecting the test results.

[0026] Furthermore, the driving assembly includes four mounting plates 12, and the four mounting plates 12 are fixedly connected to the inner wall of the groove 2. A limit rod 13 is fixedly connected between the two mounting plates 12 on the right side, and a threaded rod 14 is rotatably connected between the two mounting plates 12 on the left side. The upper end of the threaded rod 14 rotates through the upper surface of the mounting plate 12. A motor 15 is fixedly connected to the inner wall of the groove 2, and the output end of the motor 15 is fixedly connected to the threaded rod 14. A displacement plate 16 is threadedly sleeved on the outer surface of the threaded rod 14.

The inner wall of the groove 2 is rotatably connected with an outer gear cylinder 19, and the bottom wall of the groove 2 is fixedly connected with a limit block 20.

The lower surface of the L-shaped plate 17 slides through the interior of the detection platform 1, and the right side surface of the toothed plate 21 is fixedly connected with two push rods 22. The right ends of the two push rods 22 are in contact with the left side surfaces of the two second protrusions 11, and the threaded rod 14 is driven to rotate by the motor 15. Since the movement trajectory of the displacement plate 16 is restricted, the displacement plate 16 will be synchronously driven to move in the vertical direction when the threaded rod 14 rotates. When the displacement plate 16 moves, the detection probe will be synchronously driven to descend, and the L-shaped plate 17 is used to drive the teeth 18 to move. After the teeth 18 move, the outer gear cylinder 19 is driven to rotate. When the outer gear cylinder 19 rotates, the toothed plate 21 is driven to move horizontally. When the toothed plate 21 moves, the push rod 22 is used to push the second protrusion 11 to move.

During the descent, the dust cover 5 will be automatically opened without the need for additional operation by the staff, and the dust cover 5 can be automatically reset when the detection probe is raised after the detection.

[0027] Working principle: When conducting a test, place the test bottle 4 inside the storage groove 3, and then use the driving component to push the second protrusion 11 to move. When the second protrusion 11 moves, it will synchronously drive the dust cover 5 to move. When the dust cover 5 moves, it will synchronously drive the L-shaped rod 6 to move. When the L-shaped rod 6 moves, the reset disk 8 is slidably connected to the L-shaped rod 6, and there is a spring 10 pushing the reset disk 8. Therefore, when the L-shaped rod 6 moves, the reset disk 8 will not move. When the reset disk 8 slides to contact the inner wall of the sliding groove 7, it will be driven by the L-shaped rod 6, and the spring will be compressed with the help of the reset disk 8. 10, and at this time, the dust cover 5 moves to open the detection bottle 4, and the threaded rod 14 is driven to rotate by the motor 15. Since the movement trajectory of the displacement plate 16 is restricted, when the threaded rod 14 rotates, it will synchronously drive the displacement plate 16 to move in the vertical direction. When the displacement plate 16 moves, it will synchronously drive the detection probe to descend, and use the L-shaped plate 17 to drive the teeth 18 to move. After the teeth 18 move, they drive the outer gear cylinder 19 to rotate. When the outer gear cylinder 19 rotates, it drives the tooth plate 21 to move horizontally.
