[0016] (III) Beneficial Effects
[0017] This utility model provides a portable medical experimental graduated cylinder, which has the following beneficial effects:
[0018] 1. This portable medical laboratory graduated cylinder, through the configuration of a motor, lead screw, slider, and movable plate, allows for easy removal of the graduated cylinder. First, the motor is started to drive the lead screw to rotate, which in turn drives the slider, which is threaded to it, to move linearly along the axial direction of the lead screw. This causes the movable plate to move synchronously. When the movable plate moves upward, it generates an upward thrust on the graduated cylinder, thereby pushing the graduated cylinder upward from the inside of the casing, thus enabling the removal of the graduated cylinder. This allows for faster and more efficient removal and replacement of the graduated cylinder, saving operation time and improving work efficiency.

This portable medical laboratory measuring cylinder, through the arrangement of a T-shaped slider, pressing block, connecting plate, spring, and locking rod, allows for easy removal of the fixing strap when the fixing strap needs to be disassembled. First, press the pressing block to move it into the cavity, causing the connecting plate to move along with it. Simultaneously, the spring is compressed, causing the locking rod to disengage from the round hole of the T-shaped slider. At this point, the T-shaped slider is no longer restricted by the locking rod, allowing it to be removed from the T-shaped groove. This enables the disassembly of the mounting plate and fixing strap connected to the T-shaped slider. By replacing the fixing strap with different sizes according to actual needs, it can adapt to different application scenarios and requirements, exhibiting high versatility and applicability.

The graduated cylinder 2 is connected via the motors 4, lead screw 5, slider 6, and movable plate 7. The setup is such that when the measuring cylinder 2 needs to be removed, the motor 4 is first started to drive the lead screw 5 to rotate, which in turn drives the slider 6, which is threaded to it, to move linearly along the axial direction of the lead screw 5. This causes the movable plate 7 to move synchronously. When the movable plate 7 moves upward, it will generate an upward thrust on the measuring cylinder 2, thereby pushing the measuring cylinder 2 upward from inside the outer shell 1, thus realizing the operation of removing the measuring cylinder 2. This allows for faster and more efficient removal and replacement of the measuring cylinder 2, saving operation time and improving work efficiency. Two fixing blocks 8 are fixedly connected to the surface of the outer shell 1. A T-shaped groove is opened on one side of the fixing block 8, and the inner side of the T-shaped groove...

A connecting plate 11 is fixedly connected to one side of the pressing block 10. A spring 12 is connected between one side of the connecting plate 11 and the inner wall of the cavity. A locking rod 13 is fixedly connected to the other side of the connecting plate 11. A circular hole matching the locking rod 13 is formed on one side of the T-shaped slider 9. The locking rod 13 engages with the inside of the circular hole. A mounting plate 14 is fixedly connected to the top of the T-shaped slider 9. A fixing strap 15 is fixedly connected to the tops of the two mounting plates 14. The T-shaped slider 9 and the pressing block 10... The connection plate 11, spring 12, and locking rod 13 are configured such that when the fixing strap 15 needs to be removed, first press the pressing block 10 to move it into the cavity, which will move the connection plate 11 together and compress the spring 12 at the same time, so that the locking rod 13 disengages from the round hole of the T-shaped slider 9. At this time, the T-shaped slider 9 is no longer restricted by the locking rod 13, and the T-shaped slider 9 can be taken out from the T-shaped slide groove, thereby realizing the disassembly of the mounting plate 14 and the fixing strap 15 connected to the T-shaped slider 9. In actual situations, by replacing the fixing strap 15 with different sizes, it can adapt to different application scenarios and needs, and has high versatility and applicability.
[0029] A limiting block 16 is fixedly connected to the other side of the slider 6. By setting the limiting block 16, the limiting block 16 can ensure that the slider 6 moves in a specific position. A limiting groove adapted to the limiting block 16 is opened on the inner side wall of the outer shell 1. The limiting block 16 is movably connected to the inner side wall of the limiting groove.
[0030] Protective pads 17 are fixedly connected to the inner side wall of the outer shell 1 and the top of the movable plate 7.

[0036] The second step: Next, press the pressing block 10 to move it into the cavity, which will move the connecting plate 11 together and compress the spring 12 at the same time, so that the locking rod 13 disengages from the round hole of the T-shaped slider 9. At this time, the T-shaped slider 9 is no longer restricted by the locking rod 13, and the T-shaped slider 9 can be taken out from the T-shaped slide groove. Then, the mounting plate 14 and the fixing strap 15 connected to the T-shaped slider 9 can be disassembled. By replacing the fixing strap 15 with different sizes according to the actual situation, it can adapt to different application scenarios and needs, and has high versatility and applicability.
